Virtually all elective surgical services around the world suffered some form of shutdown due to the COVID-19 pandemic1. Now, patients and surgeons are desperately looking to re-start services. Efforts to re-start after the first waves faced multifactorial challenges, including patient safety and ensuring enough staff along the whole patient pathway to support operating theatre availablity.2,3

The impact of the reduction in surgical capacity is likely to be staggering. Initial estimates of 28 million cancelled operations likely escalated to 50 million towards Autumn 2020, and may now be in excess of 100 million. That is only one part of the story, since the many undiagnosed patients with surgical conditions sitting in the community over the last 12 months may never make it to a surgeon or waiting list. Without adequate surgical capacity, there will be a major global decline in population health due to the burden of a full range of inadequately treated non-communicable diseases. 

There is no single factor or solution that will enable surgery to re-start at scale, quickly. There is no single set of solutions that will work across every region. Since every single hospital around the world functions differently, context specific and whole system solutions are needed. 

Vaccination will hopefully provide solutions to the current pandemic, although the global rollout is occurring at different paces globally, meaning surgical recoveries will differ. Cultural challenges across countries are adding to this variation. Unlike acute major incidents which disable elective surgical but are quickly over (e.g. major trauma or bombings), this pandemic has exposed specific, longer-term weaknesses of current systems. Post-pandemic planning will now happen across all spectrums of society. Surgeons need to lead efforts to create resilient elective surgical services that are pandemic resistant for the future, advocating for hospital and political awareness. 

The COVIDSurg collaborative has taken a data driven approach to supporting safe surgery, and for 2021-2022 will provide further data to support re-starts globally. Data is needed across the whole system and patient pathway, that includes referrals, preoperative selection, perioperative testing and safety, postoperative risk reduction, and structural organisation of hospitals4–6

Learning from other non-medical disciplines, surgeons have little barometer of how secure their elective surgical services are compared to everyone else’s. COVIDSurg will deliver a validated Elective Surgery Resilience Index in the first half of 2021, allowing surgeons to test their systems and identify areas for immediate strengthening. 

Re-starting surgery safely will be a complex interplay of these multiple factors. Not all resources will be available across all regions, and in some resource limited settings, surgery is at risk of being seen as a burden. To further support the re-start, an easily accessible, digital, online toolkit is needed that will provide key take-home messages and downloadable pathways for surgical teams to take and adapt. This will include the ability to self-certify individual department and hospital level of COVID Secure Surgery. This will provide the building blocks to provide ring-fenced, pandemic secure surgery by 2030.

The epicentre of the SARS-CoV2 outbreak has been shifting from place to place, hitting many countries in the world. The feelings of angst, distress and desperation have also spread along with the virus among healthcare workers (HCW). It is hard to forget the early voices from the frontline HCW, the rapidly worsening situation during the escalating phase,1which seems to be occurring again in countries that are being hit by the second wave.2

The early working experience originally narrated by an Italian doctor Daniele Macchini. English translation by Silvia Stringhini on twitter.

Surgeons’ fear of getting infected by SARS-CoV-2 and developing COVID-19, as well as the change of their daily surgical practice, has been described since the early stage of the pandemic.3 Despite the varying rates of infected people among countries, surgeons have experienced globally a common angst about the virus due to their high-risk job. 

China, as the first country facing the virus, had limited previous knowledge and experience about COVID-19 to refer to. The HCW were immediately frightened by what they witnessed: emergency rooms filled with patients infected by an unfamiliar type of virus, followed by overwhelmed intensive care units. Since the escalation of the epidemic in Wuhan was so rapid, most elective surgeries in China were cancelled and not resumed until mid-March 2020.4 The fear of the unknown had forced most hospitals to stop surgical practice, leading to a serious backlog of surgical patients. Due to lack of staff, many surgeons were frequently re-employed to work in intensive care unit or fever clinic, causing a feeling of inadequacy to work in a medical area for which they were not trained. During the post-epidemic period, the mental stress among surgical staff persisted due to the extensive surgical backlog and the additional work involved in ensuring a safe environment for newly hospitalized patients through creation of selective safe routes and adequate personal protective equipment (PPE) adoption.5

Surgeons in Europe have probably suffered even worse situations. Fear of getting infected has led HCW to feel a threat to their life because of their work. In the early phase, a vascular surgeon from the UK spoke out about such dreads, and acknowledged the importance of looking after surgeon’s mental well-being.6 Otolaryngology-ENT, and maxillofacial specialties were regarded as those at highest risk, therefore, a team from the Head and Neck Unit of the Royal Marsden NHS Foundation Trust and Lewisham Child and Adolescent Mental Health Services analysed the impact of COVID-19 on the mental health of surgeons. The fear of contracting the virus and transmitting to family members represented important factors affecting mental health of HCW during the pandemic.7 Many HCW were self-isolating from their family and many decided to left their homes, while others moved into their garages and basements.8, 9

In US, where the pandemic hit in the summer, surgeons also expressed their angst during work. Shortage of PPE and lack of a coordinated pandemic plan from the central government further exacerbated the fear. During the early phase of the pandemic, surgeons from US declared “guilt and fear are to some extent pervasive in medical practice”, “any provider during this time that says they aren’t impacted is not being truthful with themselves”.10, 11

Another key element that has generated stress among doctors has been the uncertainty of how to treat a completely unknown disease. Data were lacking and indications were changing frequently, causing confusion and misinformation. An explicative example is given by guidelines on use of surgical masks: WHO and many governments initially banned the use of adequate PPE in hospital daily practice when dealing with asymptomatic people, due to lack of scientific evidence and lack of stock of PPE.

Surveys among HCW have become a fast and effective way to provide updated data to guide medical choices during this unprecedented time.12, 13 A survey from Mexico investigated personal feelings among 150 vascular surgeons; with ten short but detailed questions, the results of the survey showed that the greatest fear was to infect their families. More than half of the respondents thought that PPE supply was inadequate and 61% of the respondents did not agree with the way government and the Health secretary have handled the pandemic.14

Another regional survey from a tertiary academic centre in Singapore investigated psychological health condition among 45 surgical providers during the pandemic. The results revealed that 77.8% of respondents were experiencing fear of contracting COVID-19, and 88.9% reported fear of spreading the virus to their families. Doctors in training suffered worse mental health condition than other colleagues;15 a national survey explored factors associated mental health disorders among 1001 young surgical residents and fellows in France, finding that enough PPE supply and sufficient training on preventing COVID-19 could decrease the possibility of developing anxiety, depression and insomnia.16During early April 2020, the S-COVID Collaborative conducted a global survey among surgeons from 71 countries, revealing that the fear of getting infected by COVID-19 or infecting others was indeed very common among the respondents from all over the world. Furthermore, the analysis showed that shortage of surgical masks, dissatisfaction towards hospital’s preventive measures and experiencing in-hospital infections were associated with surgeon’s fear.17

Indeed, factors associated with surgeons’ fear, elicited from the above global survey, are preventable. Since comprehensive meta-analysis and reviews have clarified the effectiveness of face masks,18 and additional supply strategies have been established,19 the shortage of face masks and other PPE could be fully managed. Another action which could reduce anxiety and stress of the HCW would be intensive SARS-CoV-2 screening. In Wuhan, universal screening for all 10 million residents was completed in May. “The physical lockdown on the city was lifted on April 8, and after the testing campaign was finished, the psychological lockdown on Wuhan people has also been lifted.” Such universal screening would also reassure the surgeons as well as other HCW.20, 21

Unfortunately, before the normal life and work could be resumed (even if known as “new normality”), the second wave of the pandemic started. Sentiments of fear, angst, anxiety are likely to impact heavily citizens and HCW. The surgical staff is already facing heavier workload due to the backlog of surgical patients during the pandemic – which might be even worse, as many did not have enough time to recover from the first wave. If one takes into account that more than 28 million elective surgeries have been cancelled or postponed worldwide,22 the resulting picture is extremely worrisome. Besides the upcoming enormous workload, asymptomatic COVID-19 patients are still acting as threats for hospitals, making the daily work of surgeons harder than usual.23

It is well acknowledged that surgeons are always working under great pressure, burnout due to work is a common finding among surgeons.24 However, the pandemic has generated an unprecedented situation, in which HCW are being overwhelmed by their angst and fears. Medical litigations are also likely to increase in the next months, adding to HCW sense of uncertainty and inappropriateness.25 It is mandatory that the public opinion, the press and social media contribute to offer a balanced and realistic overview of the conditions in which HCW are being forced to work; and that societies and entities collaborate to create strategies to prevent such conditions,26 and to help HCW who are struggling, left alone.

Guest post: Mental health and BRCA

Exploring psychological consequences for BRCA+ women in the post-Covid era

Whilst the global female population has a 12.5% overall lifetime risk of developing breast cancer and a 1.3% risk of ovarian cancer (Howlader et al), the risk for those with a pathogenic BRCA1 or BRCA2 mutation is 60-70% and 10-20% respectively (van Egdom et al). BRCA1 mutation carriers have a particularly high incidence of triple-negative breast cancer (TNBC) (Greenup et al) for which treatment options are more limited and always include chemotherapy (Bianchini et alCollignon et al). 

In the NHS, asymptomatic women with at least a 10% estimated chance of having a BRCA mutation are offered testing (NICE).  Knowing you are at high risk of breast cancer and the increased likelihood of TNBC is a well-documented  cause of anxiety (Wenzel et al) and many women describe having a BRCA gene mutation as living with a ‘ticking time bomb’. Bilateral mastectomy with or without reconstruction is the only proven method of drastically decreasing risk and can improve quality of life (McCarthy et al) and decrease anxiety (Rebbeck et al) for correctly selected cases, despite its potential negative outcomes (Gahm et al). 

The strongest predictor for choosing to undergo risk reducing mastectomy is having a first or second degree relative die from breast cancer (Singh et al), a factor associated with fear, anxiety and vulnerability to this disease.  Most women choosing it have clear and long-considered reasoning and have been prepared for it through well-established pathways guided by genetic counsellors, specialised surgeons and nurses.  It is however, classified as elective surgery. As such, waiting lists for risk reducing mastectomies are impacted by other healthcare challenges and needs. 

Being on NHS waiting lists causes anxiety across all specialities (Carr et al). With an estimated 10 million people on NHS waiting lists in the post-COVID era, levels of health-related anxiety within the population are anticipated to significantly increase. For BRCA mutation carriers, the prevailing fear is that they will develop breast cancer whilst on the waiting list.  This reality is related to the length of time on the waiting list and represents potential conversion of a risk reducing scenario to one of chemotherapy and cancer surgery, often with other treatments, and all the life changing and life threatening implications of cancer diagnosis.   

In pre-COVID times, there was a 18 week target time from referral to treatment for risk reducing mastectomy (UK GOV). Due to COVID, the majority of elective surgery has been put on hold and Breast Units now anticipate at least a 2-year waiting list for non-cancer surgery, such as risk reducing mastectomies, delayed reconstructions, and revisional surgery. Prioritisation is a difficult necessity.

In addition, breast screening services ceased or were significantly curtailed as a result of COVID related restrictions, and this adds to an already complex situation for BRCA mutation carriers.  Not only may they now get breast cancer whilst on the waiting list, but they are denied the reassurance afforded by negative screening, or potentially a diagnosis may be delayed (Maringe et al). 

Combining pre-existing anxieties of being a BRCA mutation carrier, new waiting list anxieties, and wider COVID general health anxieties, the post-COVID era has the potential to see significant levels of psychological burden in this population, which could negatively impact mental health and quality of life. Providing additional psychological support is likely to be the short-term solution, though this is also resource limited. In reality the collateral impact of pandemic related consequences for healthcare in this particular group may not be realised for some time. 

Plain English Summary: How the first COVID‐19 wave affected UK vascular services

Global overall mean service reductions, worldwide response, and service reduction scores in the UK and the Americas
Global overall mean service reductions, worldwide response, and service reduction scores in the UK and the Americas

The COVID-19 pandemic has impacted healthcare around the world. Patients who have vascular disease (problems with their arteries or veins), are at high-risk of having complications if they develop COVID-19. This is because patients with vascular disease usually have many medical problems. Some of them are also elderly and might be frail. We do not know how the COVID-19 pandemic might have affected the care of patients with vascular disease. 

The COVER study is an international study trying to assess how the COVID-19 pandemic changed the medical care of patients with vascular disease. The first part of the COVER study was an internet survey. In this survey, doctors and healthcare professionals were asked questions (every week) about the care of vascular patients at their hospital. The results were published in this article.

The results showed that the COVID‐19 pandemic had a major impact on vascular services worldwide. Most of the 249 hospitals taking part from 53 countries, reported big reductions in numbers of operations performed and the types of services they could offer to patients with vascular disease. Almost half of the hospitals stopped doing routine scans to detect artery problems and a third had to stop all clinics in the height of the pandemic. There were major changes in the resources available to treat blocked leg arteries. Most non-urgent operations, especially for vein problems, were cancelled.

In the months during recovery from the pandemic peaks, there will be a big backlog of patients with vascular disease needing surgery or review by vascular specialists.

A COVID challenge

One of the consequences of COVID-19 has been greater attention on the risks of infection to clinicians. Much has been made of the need for personal protective equipment, including FFP3 masks, visors, and respirator hoods. Unfortunately these can also impact on communication. This can be due to muffled speech, or loss of ability to read lips. This is important in an operating theatre, where clear communication is critical.

Experience suggests that surgeons probably use some gestures to aid communication when operating. The use of sign language in clinical settings has been previously addressed in the literature, mainly as a proposal to manage increased noise levels in the OR. Sign language has also been suggested as an alternative to handle language differences in surgical team members of varied nationalities, as well as to improve action response within a procedure.

A new sign-language?

To reduce verbal communication that may be limited by impaired speech or hearing, the authors have proposed a surgery-specific sign language. The vocabulary consists of technical information that is easy to learn and replicate and allows fluent communication in the OR. These are summarised in the video above.

Key questions in the diagnosis and management of appendicitis

questions about treatment of appendicitis

Salomone Di Saverio (@salo75) Consultant General and Colorectal Surgeon, Professor of Surgery, University of Insubria, Regione Lombardia, Italy;

Key questions in the diagnosis and management of appendicitis

Throughout my surgical training, decision making and risk prediction in patients with a clinical suspicion of appendicitis has been a prominent challenge. The accurate diagnosis of appendicitis should lead to improved healthcare provision to the patient, however there is still debate amongst the use of tools and imaging to assist this. The appropriate use of antibiotics to manage appendicitis, and the use of operative techniques to remove the appendix, have recently become a global debate.

Diagnosis of appendicitis

I have personally found the diagnosis of appendicitis to be challenging, with presenting history and examination of patients with right iliac fossa pain variable and often confounded. Clinical risk scores have recently been investigated through prospective international collaborative studies.1 The Alvarado score was one of the earliest scores demonstrating efficacy in appendicitis diagnosis when confirmed to histopathological diagnosis leading to its widespread uptake.2 However, this been superseded by the Appendicitis Inflammatory Response score (AIRS) in males and Adult Appendicitis Score (AAS) in females which have demonstrated improved performance in a pragmatic clinical setting.1

I have often been taught that appendicitis is a diagnosis made on clinical judgement alone and I feel this has become one of the most prominent dogmas present in surgical practice. The use of AIRS and AAS have been recognised to decrease negative appendicectomy rates in low-risk groups and reduce the need for imaging.1,3 I believe that the use of risk scoring should be taught to all surgical trainees routinely as a standard work up for the assessment of right iliac fossa pain.

Recent news reports have disseminated to the public that “Thousands of young women have their appendix removed unnecessarily”4 and although this may represent the appropriate conservative approach to imaging in females, it emphasises that we cannot justify ignoring the diagnostic tools at our disposal. Point of care ultrasound is recommended by the World Society of Emergency Surgery for decision making as a first point of call in both adults and children, however operator variability is noted.3

In my experience, and as per the general consensus of the departments I have worked in, ultrasound imaging is often useful in female patients to identify any ovarian cause of right iliac fossa pain and inconclusive for appendicitis. However, I can envision the use of ultrasound as part of clinical-radiological scores to enhance the sensitivity of diagnosis and could assist in avoiding radiation exposure through CT scan, which remains a pertinent research question.

Non-operative and operative management of appendicitis

Mirroring teachings in the diagnosis of appendicitis, in my experience it is taught that there is only one definitive management plan for simple appendicitis – an emergency appendicectomy. When considering modern sources of evidence, my belief is that the UK national normal appendicectomy rate (NAR) of around 20% is too high, when compared to countries such as Switzerland where the NAR has been found to be around 6%.5 The high NAR in the UK was again picked up by British media outlets who published headlines such as ‘Unnecessary appendix surgery performed on thousands in UK’.4

Antibiotic-first strategy has been found to be safe and effective in selected patients with uncomplicated acute appendicitis however, the risk of recurrence has been suggested to be up to 39% after 5 years.3 A 2019 meta-analytical review of 20 studies (7 prospective RCTs, 8 prospective cohort studies, 4 retrospective cohort studies and 1 quasirandomised study) investigated outcomes in non-operative management with antibiotics in appendicitis with an overall moderate quality of evidence when regarding complications and treatment efficacy.6 Overall antibiotic therapy achieved a significantly lower post-intervention complication rate including postoperative abscesses, surgical site infections, incisional hernias, obstructive symptoms, and other general operative complications at 5 years compared to index event surgery.6 However, there was a lower complication free treatment success rate and a non-significantly higher rate of complicated appendicitis with delayed surgery in patients receiving initial antibiotic therapy.6

I feel that the stratifying of patients by risk and utilisation of outpatient surgical ambulatory units with repeated history taking, observations, and blood tests could be effective in reducing the NAR in the UK with or without imaging. Accurate diagnostic imaging in the form of a CT scan could reduce the UK’s NAR further, improving patient outcomes, surgical planning, and healthcare service provision at an organisational level. This may outweigh the impact of radiation exposure of a CT abdomen scan which has been well described by Aneel Bhangu the lead director of the RIFT/West Midlands Collaborative as giving “the same radiation as flying to New York”.4 T

his is a risk which I believe many would not be concerned about when travelling. This view is in opposition to that of the recently updated World Society of Emergency Surgery guidelines which suggest that CT imaging may be avoided prior to laparoscopic operation, but it should be noted that there was debate regarding this within the writing committee.3

I believe that more care must be taken in patients with suspected appendicitis to undertake a discussion around imaging use, operative management, and non-operative management which is unbiased and evidence based. Those opting for conservative management should be warned of the possibility of failure and misdiagnosis of complicated appendicitis. In my training so far, conservative management has been discussed in those judged to be low-risk however this does not come without the risk of the on call surgeon’s bias seeping into conversation. Further research should be undertaken to identify precisely which cohort of patients are optimal for non-operative outpatient management.

Appendicitis and COVID-19

Recent research into risk scoring in appendicitis has demonstrated a clear benefit in stratifying patients into risk categories to guide management plans.1,3 As highlighted I believe that all patients presenting with right iliac fossa pain should undergo scoring, by either AIRS or AAS. It has been suggested that due to local population characteristics and health systems, risk scores should be validated locally prior to routine adoption.7 It has further been emphasised that risk score models should not replace clinical judgement and should be used as an adjunct to enhance decision making.8

In the current COVID-19 pandemic the use of non‐operative management has been suggested to be increased for acute surgical conditions such as appendicitis9 and this has been the experience of my department. The evidence at present suggests that this is safe and feasible, and therefore the COVID-19 pandemic presents a unique period for investigation.10 It could be a valuable endeavour for all centres to perform local analyses of the impact of conservative management on patients presenting with right iliac fossa pain in the COVID-19 period.

This is also being undertaken on a national level in the COVID- HAREM Study: Had Appendicitis and Resolved/Recurred Emergency Morbidity/Mortality. Locally, one year clinical outcomes could be measured for those diagnosed with appendicitis pre-COVID and during the COVID period. Finally, with the restoration of normal patient pathways post-COVID, risk scoring could be introduced to local departments with a pre-COVID / post-COVID comparison to allow for the clear demonstration of any benefit to the patient.

Background:

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the virus responsible for the 2019 Coronavirus Disease (COVID-19). The main route of transmission is through droplets and close contact.1,2 As a result of their mass, droplets spread in space is limited to 1-2 meters from the source of production. Aerosolized particles, on the other hand, are smaller in size (0.3 to 100 micrometers) and have been documented to linger in the air longer than droplets and travel up to hundreds of meters before settling on a surface.3 The role of aerosolized particles in the spread of SARS-CoV-2 in the community has yet to be proven, however, their presence in the hospital setting has been of greater concern.4–6

The earliest documentation of infection coming out of Wuhan, China showed that 40 out of the first 138 (29%) people infected by SARS-CoV-2 were healthcare workers.7 In an effort to help minimize the spread of SARS-CoV-2, several hospitals have published their approach to the surgical management of infected or suspected COVID-19 patients. A recent PubMed search for “COVID-19” and ”surgery” yielded 224 results, of which 13 papers proposed detailed precautions when surgically managing a COVID-19 positive or suspected patient. From setup to post-operative management, this review will draw from the suggestions of these papers and outline some of the most commonly mentioned precautions. As many institutions have never experienced such a dramatic shift from their day-to-day operations, this document may provide useful information with regards to safe practice.

Studies referenced in this review.

The Role of Hospital Management:

The majority of COVID-19 infected or suspected patients will not require surgical intervention throughout the course of their disease. Therefore, mainstream procedures and precautions focus on the management of respiratory distress, proper isolation of patients, safety of ICU personnel and emergency department organization.8 Senior surgeons should be heavily involved in the supervision of focused training and the development and update of protocols.9 All personnel should be familiarized with specific procedures related to 1) COVID-19 patient transport to the operating room (OR) 2) intra-operative, and 3) post-operative care.

Pre-Operative Precautions

A predesignated route should be the shortest possible distance from isolation to the OR. It should be cleared by security, use isolated elevators and have minimal contact with others.10 A recent study by van Doremalen et al. found that the survival time of SARS-CoV-2 on plastic and steel surfaces such as elevator buttons can last as long as 72 hours, thus supporting the notion of using separate lifts and routes for patient transportation.4

With Regards to operating theatres, all studies suggested the use of negative pressure environment to reduce the dissemination of viral particles.1,5,11–21 Van Doremalen et al. also found that in aerosolized form, SARS-CoV-2 can remain viable for up to three hours.4 Applicably, the use of a high frequency (25/hour) air exchange can significantly reduce viral load within the OR.17 All drugs and equipment should be prepared before the start of surgery to limit movement of staff in and out of the OR.17 Anaesthetic drugs should be placed on a tray to limit contact and potential contamination of the drug trolley. Hand washing and glove change should be performed in any case were additional supplies must be accessed from the trolley.20 Monitors, ultrasound machines and other devices that are difficult to disinfect, should be covered by transparent plastic wrap to decrease the risk of contamination.17

Personal Protective Equipment

Of the 13 studies reviewed, all recommended the use of eye protection in the form of goggles or a face shield as well as a filtered face-piece respirator (N95).1,5,11–21 Five out of 13 studies recommended the use of powered air purifying respirators (PAPRs)(protection factor of 25-1000) as a superior alternative to N95 respirators (protection factor of 10).1,11,17,18,20,22 In addition to the higher protection factor, PAPRs provide eye protection and unlike the N95 respirator, do not require fit testing.18,17 Finally, five out of 13 studies suggested the use of double gloves during intubation and/or surgery.12,17–19,23 Forrester et al. also recommended the implementation of a buddy system during donning and doffing to identify any breaches in protection which can be decontaminating using alcohol spray.5

Intra-Operative Precautions: Anaesthesia and Surgical Smoke

Five of the 13 papers analyzed were sent to anaesthesiology journals and focused mainly on the minimalization of viral aerosolization during induction of anaesthesia and extubation.1,15,17,19,20 Some suggestions include the use of shortest acting drugs at lowest possible dose, avoidance of awake intubation and aggressive post-operative antiemetic prophylaxis to avoid aerosol production during emesis.1,17 Four studies recommended that pre-assessment, induction and post-operative anaesthesia recovery should all take place within the procedure room.12,17,19,20 Patient documentation should be done electronically, if possible, on a tablet or iPad, which can be disinfected after handling.17

Previous studies have demonstrated that ultrasonic scalpels and electrocautery equipment produce surgical smoke or plume, capable of transmitting active viruses in aerosolized form.24–26 The risk of SARS-CoV-2 aerosolization via electrical surgical equipment has not yet been shown, however, several sources recommend the implementation of appropriate precautions. A recent publication by Zheng et al. suggested that the aerosol formed during laparoscopic surgery accumulates in the abdominal cavity.14 Sudden release of trocar valves and deflation of pneumoperitoneum may expose the healthcare team to aerosolized viral particles.21 Therefore, some collegiate bodies suggest the use of laparoscopy, only in select cases where clinical benefit to the patient substantially exceeds the risk of potential viral transmission to the environment and OR staff.27

Other committees indicate that the evidence of such viral transmission during minimally invasive surgery is weak, but nevertheless proper safety measures are recommended. The Society of Gastrointestinal and Endoscopic Surgeons (SAGES) and the American College of Surgeons recommend the liberal use of suction devices and smoke evacuators to limit surgical smoke release into the OR.14,16 Gas filtration systems such as the ultralow particulate air filter (ULPA) might potentially achieve COVID-19 purification of the surgical plume, but this has still to be confirmed.28

Post-Operative Precautions

When doffing PPE, the first pair of gloves must be removed first, followed by the surgical gown, shoe covers, cap and goggles. The face mask must then be removed by the ear laces, taking care not to touch the external side. The second pair of gloves must be removed last.29 Upon leaving the operating theatre, all staff should take a whole-body shower before changing into clean scrubs and returning to their clinical duties.12,16,17,20

With regards to disinfection, the United States Environmental Protection Agency (EPA) has created a list of products for use against SARS-CoV-2.30 The most commonly mentioned protocols suggest the use of sodium hypochlorite, chlorine containing disinfectant, wipes that contain quaternary ammonium and alcohol, hydrogen peroxide vaporization, and ultraviolet (UV-C) light (for inactivation of aerosolized viruses).15,17,19,20,31

A major constraint reported by several centers is the shortage of PPE such as masks and gowns. Dr. Peter Tsai, the inventor of the N95 respirator, has made several suggestions regarding the re-usability of his equipment. The first recommendation is air drying for 3-4 days.32 Alternatively, masks can be oven dried for 30 minutes at 70oC.32,33 More recently, a study out of Duke University evaluated the utilization of hydrogen peroxide vapor to decontaminate N95 respirators. This validation study concluded that N95 respirators still met performance requirements even after 50 disinfections.34 It is important to note, however, that these recommendations are constantly changing and it is of utmost importance that healthcare professionals regularly assess the most up-to-date guidelines regarding N95 re-usability and the disinfection process.

Conclusions:

The conclusions drawn from the present literature are limited by the novelty of this disease. Most of the studies presented in this review were viewpoints and recommendations based on personal experience. Due to limited experience of single institutions, efforts should be made to increase international collaboration in the era of this unprecedented pandemic. Specific data on the risk of infection among surgeons has not yet been documented, however, this should not undermine the importance of strong occupational safety. The included studies suggest a need to develop a universal, effective and affordable protocol for perioperative management of COVID-19 patients to ensure surgical staff wellbeing.

Background

The COVID-19 pandemic poses an acute threat to human health that is unprecedented in our lifetimes. Many health systems still continue to grapple with the volume of critically ill patients suffering from the virus.. The impacts of this crisis on surgical systems are being felt worldwide by patients and surgical providers. The estimated 30% of the global burden of disease caused by surgical conditions does not pause during a pandemic.1 Each year, 16.9 million people die due to surgically treatable conditions,2 and 15.2 million new cancers are diagnosed, 80% of which will require surgery.3 The magnitude and immediacy of the threat from COVID-19 has led many jurisdictions to cancel elective surgery to preserve precious hospital and critical care beds and limit nosocomial spread of the virus. As local trajectories of the pandemic become clear, surgeons and policymakers need to determine an optimal approach to meet population-level surgical needs to avoid additional pandemic-related morbidity and mortality.

Surgical systems are logistically demanding and interconnected networks of services: adaptation to the realities of limited operating theater availability is therefore complex. Human resources will also be threatened;4 safeguarding healthcare workers despite finite availability of personal protective equipment further adds to service delivery challenges. High-volume surgical systems must have the flexibility to systematically scale back provision of surgical care in a way that makes optimal use of resources while minimizing impacts on patients, providers, and systems. Looking at structured ways to operationalize sudden reductions in resources quickly, all countries can learn from existing principles and frameworks in the global surgery literature. Indeed, in addition to advocating for the health and economic benefits of investment in surgical systems,2 the global surgery literature recognizes and addresses the challenge of working under constraint. 

Prioritization of Surgical Services 

Surgical societies have provided guidance to surgeons as to which procedures are essential during this crisis.5,6 Such determinations are based on acuity, complexity, and population burden of disease. In a “must do, should do, can do” procedural framework,2 most surgeons have found themselves limited to providing only the first category: high value procedures (i.e. some cancer surgery) where long-term outcomes may hinge on timely surgical intervention, and urgent life- or limb-saving procedures. Should-do procedures are important but not vital procedures that may be amenable to a temporary workaround and still add value in the long run. Finally, can-do procedures are ones that are often desirable but not necessary—they could be deprioritized first with a relatively smaller impact on patient outcomes. These categories ought to be reassessed as resources change, but this framework can support discussions at the system, institution, and service levels. Non-operative management of traditionally surgical conditions (eg. antibiotics for uncomplicated appendicitis or endoscopic management of an early-stage esophageal cancer) may also aid in resource conservation. Finally, trauma prevention campaigns can be implemented or scaled up to minimize the need for emergency surgery.7  

Mitigating Harm from Delays to Care 

Globally, increased delays in access to surgical care are likely. Breaking these delays down into their three constituent components may help to mitigate them.2,8 First, is the delay in seeking care. With travel restrictions or residential lockdowns, the threshold to seek answers to concerns unrelated to the pandemic will increase. Creating easy access to primary care and surgical expertise, via telehealth for example, will give populations a venue to triage health concerns. Barriers to telehealth including finance, technical considerations, and confidentiality should be addressed collectively by providers, payers, government, and regulatory colleges. Second, the delay in reaching care at an appropriate center where diagnostics and therapeutics can be applied is less amenable to a technological solution. Maintaining separate health facilities as designated non-COVID-19 centers is one strategy to allow surgical work to continue or resume shortly after the pandemic peaks. As the pandemic progresses, the number of non-COVID-19 centres are reduced proportional to need as more patients present with viral illness, expanding again once the pandemic’s initial peak has passed. Finally, mitigating the delay in receiving surgical care requires adaptive waitlist management at the hospital level when progressively narrower bottlenecks in operating room time are encountered. Managing staffing constraints and pandemic-related supply chain disruptions will be critical to ensure that the appropriate personnel and disposables are available to use operating theaters as efficiently as possible.

Stuff, staff, space, and systems and the perils of reopening

Governments are struggling to balance the devastating economic consequences of ongoing stay-at-home orders with the risk of an overwhelming second wave of infections.9 While the optimal timing and strategy for reopening the economy remain unclear, strategies to mitigate the hazard of disease resurgence include widespread testing, serological surveys to better understand community-level exposure, staged relaxation of distancing measures, and bolstering hospital capacity to manage potential new cases. What these strategies all require are staff, stuff, space, and systems, an alliterative list of necessities for global health delivery coined by Dr. Paul Farmer.10

When public health officials deem it safe to resume some elective surgery, surgical leaders can also use this model to ensure that surgery again becomes available. Staff may need to be remarshaled from deployments to other acute care services; ensuring their mental and physical health during a period of significant stress will be critical. Stuff includes not only robust supplies of the necessary personal protective equipment to safely assess, operate on, and provide postoperative care for patients, but also medications and other operating room disposables that may become scarce due to supply chain disruptions. Space implies not only physical operating room space, but also appropriate spacing between postoperative patients, ideally in individual rooms, to prevent outbreaks of COVID-19 on wards. Finally, systems are required to ensure that care pathways for infected and uninfected patients are developed, staff are trained in their implementation, and their logistics are feasible.

Integrating surgery and other acute care services into global health security

Global health security (GHS) implies global collaboration to ensure that all health systems are prepared to manage public health threats and emergencies. Historically, the GHS discourse has been focused on infectious diseases as the primary public health threat born of globalization.11 The Global Health Security Agenda is a growing community of nations and organizations formed in 2014 to respond to infectious disease threats.12 By strengthening public health systems and stopping outbreaks at their point of origin, the GHSA aimed to decrease the risk of global pandemic disease. When it comes to a pandemic, the aphorism that prevention is better than cure is true. But it is an aphorism that historically excluded surgery from the global health discourse—why invest in surgery when some surgical disease is preventable?

The Lancet Commission on Global Surgery demonstrated the scale of human suffering that results when prevention is preached to the exclusion of treatment, with five billion individuals unable to access safe, affordable surgical care when needed.2 Not all surgical disease is preventable, and not every pandemic is stopped. GHS must evolve to include health services like critical care and surgery to plan for effective treatment of patients after a pandemic has emerged. If plans to address global critical care needs were in place before COVID-19, would countries have better mobilized to support beleaguered hospitals in China, Italy, or New York? If countries had anticipated the impacts of a pandemic on surgical care, would the cancellation of all elective surgery have been necessary? While these counterfactuals are unknowable, what is clear is that health services leaders must sit at the global health security table alongside infectious disease epidemiologists and public health professionals.

Summary

COVID-19 has reached almost every country on earth, and many surgical systems have already responded to the challenges it poses. The choices made in surgical system design, both historically and recently, will determine patient outcomes in the coming weeks and months. The shock to surgical systems will not be a short one—until the majority of the population has been exposed to the virus via vaccine or illness,13 the virus will pose a unique barrier to accessing safe surgical care.

Now more than ever, we must emphasize interdisciplinary collaboration, knowledge exchange, and health equity in order to maximize the efficiency of surgical access in all jurisdictions.14 Global surgery frameworks can support adaptation to rapid shifts in resource availability. More importantly, they can be used to plan the post-pandemic delivery of surgical services, serve to reconceive routine surgical care delivery systems, and plan resource scaling strategies to build more flexibility into surgical delivery in the future.

National surgical crisis planning must become part of the health systems lexicon. Mitigating acute threats to surgical systems including natural disasters, economic downturns, workforce declines, supply chain disruptions, military conflicts, and pandemic disease is not optional: our patients’ lives depend on it.

Surgery in a pandemic

Policies and public health efforts have not addressed the impact of pandemics on the provision of surgical services and the effects on health-related outcomes on surgical patients. This also applies to the response to Coronavirus disease 2019 (COVID-19). There hasn’t been any related research or analysis despite the impact of the pandemic so far. Understanding the effects of COVID-19 on patients undergoing surgery along with the effects of this pandemic on the provision of surgical services is a fundamental step to understanding the various different effects of a healthcare emergency of that magnitude and to implement policies from the lessons learned.

Impact on surgical patients

Undoubtedly despite the global focus to encounter the pandemic itself and the need to improve provision of services and treatments related to the immediate effects of COVID-19, with intensive care playing a major role, there are still millions of patients who will need surgical treatment. Major focus should be the provision of emergency surgical care, cancer surgery and transplant surgery. There is little or no knowledge on the outcomes of surgical patients with COVID-19 related disease.

Low quality data from a case series of patients who underwent cardiac surgery and acquired Middle East Respiratory Syndrome-Coronavirus (MERS-CoV) did show very high mortality of 83.33% (1). This has major direct implications on the management of emergency surgical patients during the pandemic as well as on the ongoing provision of organ transplantation and cancer related operations. Whether major cancer surgery and organ transplantation should be delayed and for how long, in view of the possible worse outcomes during the pandemic is one of the issues that should be investigated.

Impact on surgical services

We also need to address the effects of the current pandemic on surgical services provision. It is an unprecedented situation that has already changed the way surgeons and health systems worldwide are offering surgical services. There is also very low quality evidence available from the 2003 Hong Kong Severe Acute Respiratory Syndrome (SARS) epidemic that showed significant reduction in the colorectal surgical caseload that had a major negative impact on waiting times and training (2). Although it’s certain that the impact of the current COVID-19 pandemic will be of unprecedented severity, it’s actual consequences and the implications on resources, staff allocation and training are still uncertain. Understanding the effect of the pandemic would also inform future global policy around cancer and transplantation surgery during pandemics, and the provision of surgical services in general.

A new project

There is an urgent need to understand the outcomes of COVID-19 infected patients who undergo surgery. To address the above issues we designed CovidSurg, an international group of surgeons and anaesthetists, with representation from Canada, China, Germany, Hong Kong, Italy, Korea, Singapore, Spain, United Kingdom, and the United States. Our aim is to capture real-world data and share international experience that will inform the management of this complex group of patients who undergo surgery throughout the COVID-19 pandemic, improving their clinical care and to understand the effects of the pandemic on the provision of surgical services.

Prioritising Surgical Treatment in Coronavirus Pandemic “Salford Score”

Prof Gordon Carlson CBE FRCS

Background

In light of the need to assess priorities of surgical treatment in a resource-limited environment, NHS England have set out clinical priorities for cancer surgery. However, these priorities do not take into account the vulnerability of the patient to excess morbidity and mortality in the event of Covid-19 infection. It seems evident that, particularly when undertaking elective surgery, the vulnerability of a patient to Covid-19 related morbidity and mortality might be equally important to considerations of the timing of surgery as the underlying disease for which surgery is proposed.

The resource allocation system currently in use at Salford Royal NHS Foundation Trust (which has since been adopted throughout other hospitals at Northern care Alliance) takes both of these factors into account, by producing a score based upon the need to prioritise treatment on purely disease related grounds and also the vulnerability of the patient to Covid-19. The aim is to generate a score which can be used to determine the overall surgical treatment priority of a group of patients, possibly from different surgical subspecialties, when surgical resources have become limited as a result of the Covid-19 pandemic. The score allows different groups of surgeons and hospital management to objectively determine how temporarily limited resources might be allocated. It is meant to help guide collective discussions, not to be a rigid indicator of those patients for whom surgical treatment should be deferred, and it should be used to support, not to replace MDT discussions.

Cancer Surgery Priority

The NHS England Suggested Priority for Cancer surgery is summarised in table 1 below.

PriorityDescription
Priority level 1a• Emergency: operation needed within 24 hours to save life
Priority level 1b• Urgent:operation needed with 72 hours
Based on: urgent/emergency surgery for life threatening conditions such as obstruction, bleeding and regional and/or localised infection permanent injury/clinical harm from progression of conditions such as spinal cord compression
Priority level 2Elective surgery with the expectation of cure, prioritised according to:
• Surgery within 4 weeks to save life/progression of disease beyond operability.
Based on:urgency of symptoms, complications such as local compressive symptoms, biological priority (expected growth rate) of individual cancers

NB. Local complications may be temporarily controlled, for example with stents if surgery is deferred and /or interventional radiology.
Priority level 3Elective surgery can be delayed for 10-12weeks with no predicted negative outcome.
Table 1: NHS England Suggested Priority for Cancer surgery

However we could make resource allocation easier if we devised a simple, objective and consistent way of summarising the two variables which influence decision making – clinical treatment priority and risk of COVID-related adverse outcome, into one numerical score;

The “Salford Score” simplifies this to:

  • Priority 1a = score (P)1
  • Priority 1b = score (P)2
  • Priority 2 = score (P)3
  • Priority 3 = score (P)4

Vulnerability

A second component of this relates to vulnerability of the patient in case of a COVID infection (see table 2).

Vulnerability scoreOutcome in case of COVID infection
Vulnerability level 1• Unlikely to have excess mortality (compared to a completely fit individual < 70 years old) in the event of Covid infection
Vulnerability level 2• Likely to have significant excess mortality compared to a completely fit individual < 70 years old in the event of Covid-19 infection, but would ordinarily receive invasive ventilation in that eventuality
Vulnerability level 3• Extremely likely to succumb to Covid-19 infection and would not ordinarily receive invasive ventilation in that eventuality
Table 2: Vulnerability score

Salford Score

A resource allocation score of PxV, is then calculated so that a fit patient at high risk of imminent death of underlying disease (P1or 2) and unlikely to have excess Covid mortality (V1) would score 1 or 2 (and get urgent surgical treatment), whereas a patient with a non-immediately life threatening condition (P4) for which surgical treatment could be safely be delayed for 12 weeks and who would not, as a result of severe pre-existing medical comorbidity, be intubated etc. should they develop Covid and respiratory failure (V3) would score 12 and we would not proceed to offer surgery until the current resource position changes.
