The World Health Organization (WHO) declared the coronavirus (COVID-19) pandemic on 11 March 2020 (1). This was followed by near total disruption of all sectors, including the health sector, that will have lasting impact. The WHO further warns that COVID-19 will be here for a long time. Without a known cure, preventive measures such as travel restrictions, social distancing and isolation have had obvious and hidden consequences, including disrupting access to and continuity of health care. Many countries suspended surgical services especially for elective cases (2), and access to surgical care has been a challenge (3). In sub-Saharan Africa, published guidelines to enhance the preparedness of health systems to provide essential surgical, obstetric and anesthetic services have recommended several steps aimed at reducing the risk of transmission to patients and staff, and optimizing scarce resources (3). Many surgical training programs have also been suspended. Although COVID-19 is not a surgical condition, surgery is one of the essential health services affected by the pandemic, and the surgical fraternity must adapt to the “new normal” to ensure continuity of care.
In this issue, the Annals of African Surgery presents articles on innovating and contextualizing methods (5) and materials (6,7) for surgical practice in the African context. The use of locally available banana leaf dressing (BLD) for skin grafts (6) is a good example of innovative local solutions to mitigate logistical and other challenges for imported supplies presented by COVID-19 restrictions. Although the African continent has been proportionately less affected than Europe and the Americas (4), the pandemic now places the traditional practice of medicine under the lens, and calls for innovation in the way we teach and practice surgery. Already burdened by a severe shortage of surgical workforce and weak health systems, Africa now faces worsened access to essential surgical care (9). The traditional clinical setup of surgeon–patient and surgeon–student face-to-face interactions and team practice are no longer safe and must be reassessed. Innovation, flexibility and quick adaptation of new approaches are needed for optimum safe surgical care and training, ensuring increased protection of the patient and the surgical team.
The COVID-19 virus is spread through aerosols released from an infected person’s airway when talking, laughing, coughing or sneezing. The risk of transmission is higher when individuals are less than two meters apart, or when the aerosols contaminate surfaces. This is in addition to the risk of transmission by asymptomatic patients (10).
COVID-19 provides opportunity for high-quality research in several aspects of surgical care and training. Being a new disease, there are many unknowns, and time is of the essence. Its impact on surgical care and training and the predicted long-term presence and effects call for research using various designs, methods and materials to quickly address current and future challenges to surgical health systems. The African and global surgical fraternity needs context-specific research addressing efficiency and sustainability of interventions to ensure continuity of surgical care and training during COVID-19 and future pandemics.
I propose possible research areas showing the nature of unknowns presenting as opportunities for research in surgery.
Access to care
The traditional approach to surgical care from the surgical outpatient clinics to wards and theatres has depended on person-to-person/face-to-face contact between surgeon and patient. With the new requirement for social distancing and travel restrictions in place, surgery as we know it is no longer tenable; many surgical outpatient clinics have registered decreased numbers either by design or as a consequence of the wider restrictions. This calls for research into alternative ways of delivering surgical care such as self-care, mHealth and blended care, while exploring aspects such as feasibility and cost-effectiveness. Self-care is already gaining traction as an intervention in improving patient-centered care and access to essential health, especially for sexual and reproductive health and mental health (11). Self-care in surgery has been shown to improve preoperative and postoperative performance of surgical patients (12,13). The use of mobile technology (mHealth) through call centers, helplines, emergency toll-free telephone services, telemedicine and other software for consultation, patient monitoring and treatment follow-up are only growing in Africa and have not been well studied in surgery, yet they could provide a new way of increasing access and improving care (14).
Ward, clinic and theatre set up and safety
Surgical theatres are closed environments and often depend on air-conditioning. The surgical team is made up of several members, each offering a specific service for surgery to succeed. The coronavirus has been shown to spread faster in air-conditioned, closed and congested spaces, and it is now recommended to switch off air-conditioning in theatre (15,16,17). In addition, ventilation systems are in direct contact with the patients’ airways and many procedures such as intubations, suction and endoscopy generate aerosols (18). Although the use of PPE is common in the surgical environment, the COVID-19 transmission risk may demand additional standardized operating procedures. Research is needed to inform the optimal setup and modifications necessary to ensure safety of the theatre environment.
Patient triage and selection
The provision of emergency surgical care requires intimate contact and every minute counts, posing a higher risk of infection transmission. Guidelines on how to improve surgeon and patient safety in this setting are needed, for example, guidelines on how to conduct patient triage and selection, use of PPE, disinfecting spaces, objects, and equipment, and the composition of the emergency surgical teams.
The COVID-19 positive patient
The management of the COVID-19 positive surgical patient still presents a dilemma. Various surgical societies and authorities have issued recommendations and guidelines on how to organize surgical services, prevent transmission and optimize use of the available s
