About Surgery During COVID-19


Some operations must go ahead during the pandemic and its recovery period. The CovidSurg group is a team of surgeons and researchers working together to understand how we can protect surgical patients from infection with COVID-19 and keep surgery as safe as possible.

The CovidSurg data has shown that extra breathing complications occur in patients who are infected with COVID-19 around the time of their operation and for these patients there is an increased risk of dying.

The risk of dying is associated with patient characteristics and different types of surgery. This includes a higher risk of dying for male patients, those age over 70 years and those with existing medical problems. Surgery for cancer and major surgery or emergency operations also carry higher risks. The CovidSurg team are still working to understand more about predicting risk so that surgeons and patients can make the best choices together for every patient.

If you are preparing to undergo surgery during the pandemic, the hospital team and surgeon will have considered the risks and will adjust care to keep you safe.

The resources on this page provide information about:

  • The effects of COVID-19 on surgical patients.
  • What the hospital is doing to keep you safe.
  • What you can do to stay safe.

Patient Resources


The CovidSurg Patient Information Booklets have been created to help patients and their families understand the risks of having an operation during the COVID-19 pandemic. We explain how surgical services will care for you during the pandemic and how we can work together to keep you safe.

 

Our research team have created these resources with the help of a Patient Advisory Group convened through Bowel Research UK‘s People and Research Together network. This work has attracted the attention of the BMJ and won an award for its patient Engagement and Impact.

CovidSurg Research

Covid Surg - CovidSurg

The NIHR Global Health Research Unit on Global Surgery


Improving surgical outcomes through collaborative research

CovidSurg is a platform of studies aiming to explore the impact of COVID-19 in surgical patients and services. Our studies are designed and delivered by an international collaborating group of surgeons and anaesthetists which reached more than 80 countries.

CovidSurge Item Research

COVIDSURG


Improving surgical outcomes through collaborative research

Patients diagnosed with COVID-19 who need surgery are a challenging group. Capturing real-world data and sharing international experience will inform the management of this complex group of patients who undergo surgery throughout the COVID-19 pandemic, improving their clinical care.

Primary aim

  • To determine 30-day mortality in patients with COVID-19 infection who undergo surgery. This will inform future risk stratification, decision making, and patient consent.

CovidSurg Cancer Research

COVIDSURG - CANCER


Improving surgical outcomes through collaborative research

Any centre performing elective cancer surgery affected by COVID-19 could participate in this study. Investigators could choose one or more cancer types from their centre from which to upload data. This study could be performed prospectively, retrospectively or using a mixed model, dependent on the phase of COVID-19 infection in that team’s hospital.

Primary aim

  • To evaluate the 30-day postoperative pulmonary complication rate following elective cancer surgery during the COVID-19 pandemic.

CovidSurg Week Research

COVIDSURG WEEK


Improving surgical outcomes through collaborative research

CovidSurg Week is an international multi-centre prospective cohort study in which patients from all specialities undergoing a surgical procedure done in an operating theatre could be included (any SARS-CoV 2 status).

Primary aim

  • To determine the optimal timing for surgery following SARS-CoV-2 infection.

CovidSurg Omicron

COVIDSURG 3 - OMICRON


Improving surgical outcomes through collaborative research

With the emergence of the Omicron SARS-CoV-2 variant of concern, there is currently little evidence regarding disease severity in both vaccinated and unvaccinated patients (including in surgical patients), nor is there data to guide patient risk stratification during Omicron COVID-19 waves.

This new study aims to provide renewed rapid data to guide global practice during Omicron COVID-19 waves.

CovidSurg-3 has two separate components:

  • Patient-level component: Collection of outcome data for patients with peri-operative SARS-CoV-2.
  • Hospital-level component: Collection of aggregated case-mix data. Hospitals in countries with low community SARS-CoV-2 infection rates can contribute towards this component.

Primary aim

  • To determine 30-day mortality in patients with peri-operative SARS-CoV-2 infection. This will inform future risk stratification, decision making, and patient consent.

Improving surgical outcomes through collaborative research

The GlobalSurg Collaborative was established to represent practicing surgeons from all around the world. We conduct collaborative international research into surgical outcomes by fostering local, national and international research networks.

 

The GlobalSurg network now includes over 5000 clinicians in more than 100 countries. The ethos is inclusive and collaborative: our international cohort studies are open to all collaborators, including medical students, clinical officers, doctors, nurses and researchers. Any hospital, anywhere in the world, treating patients that meet study inclusion criteria are eligible to take part.

GlobalSurg 1GlobalSurg 2GlobalSurg 3

Our international cohort studies are relevant, prospectively-run, and high quality.  We aim to give grass-root surgeons the opportunity to participate in major research projects. Each study is designed to ensure easy delivery by local surgeons and researchers, and will not require any additional resources or funding.

Working in teams of up to 3, collaborators collect data on their own patients for a defined period of time, usually 2 or 4 weeks within the study timeframe, and submit to our secure, online database. Every researcher who contributes data into a cohort study will be a Pubmed-citable collaborator on all publications arising from each study;  which will be published under one main name – GlobalSurg – to represent our group effort. See our publications page for more information.

Through three international cohort studies, GlobalSurg collaborators have collected data on >40,000 patients in more than 80 countries examining outcomes after emergency abdominal surgery (GlobalSurg 1), surgical site infection rates (GlobalSurg 2) and outcomes after surgery for breast, gastric and colon cancer patients (GlobalSurg 3).

Rwanda Hub

NIHR Global Health Research Unit on Global Surgery @Rwanda Hub


The Global Surgery Unit began its relationship with Rwanda through the creation on the National Hub at the University of Rwanda, Kigali. The development of the national programme has resulted in the orchestration of several surgical trials carried out between 12 spokes across Rwanda, in addition to the primary Hub location in Kigali.

The Rwanda Hub resides over the recruiting, training, and management of the spoke hospitals. Furthermore, the Hub encourages and involves local surgeons, medical students, public bodies and community, in the promotion of quality surgical care and access in Rwanda.

Nigeria Hub

NIHR Global Health Research Unit on Global Surgery @Nigeria Hub

The NIHR hub in Nigeria is located at College of Medicine University of Lagos and Lagos University Teaching Hospital (CMUL/LUTH)


The NIHR GSU hub in Nigeria is located at the College of Medicine, University of Lagos/Lagos University Teaching Hospital (CMUL/LUTH).

The University of Lagos is a leading Nigerian institution, dedicated to quality teaching, learning, research, and community service. The University records outstanding research breakthroughs as her research culture is fostered through supports for research collaborations, conferences, symposiums, etc. The University is also committed to the healthy living of the populace through involvement in various health researches such as that of GlobalSurg in improving the surgical outcomes of patients. With the high number of deaths due to very limited access to quality health care in Nigeria, and the common knowledge of post-surgery complications responsible for a large proportion of morbidity and mortality; the importance of the GlobalSurg research in Nigeria cannot be over-emphasized.

The Nigeria Hub is led by Prof. Adesoji Ademuyiwa, a Professor of Paediatric Surgery at the Faculty of Clinical Sciences, College of Medicine University of Lagos, and Head of Paediatric Surgery Unit, Lagos University Teaching Hospital. He is being assisted by Prof. Adewale Adisa of the Obafemi Awolowo University Teaching Hospital Complex (OAUTHC), a Professor of Surgery at College of Health Sviences, Obafemi Awolowo University, Ile Ife, Osun State.  The Hub administration is overseen by Emmanuel Williams, the National Hub Manager. He is responsible for the day to day running of the hub and delivers support to the spoke hospitals within Nigeria. He is supported by Adeola Orowale who is also the National Finance Officer.

The Hub’s Senior Research Nurse and Project Officer, Chinelo Mgbemena, supports the research projects in Nigeria. She is assisted by Moyosoluwa Ojo, the Research Nurse/Community Engagement and Involvement (CEI) Officer. Christianah Oyegbola, the National Data Manager, manages the research data of the hub and spoke hospitals.

The Nigeria Hub is currently supporting 26 spoke hospitals from Colleges of Medicine, Teaching Hospitals, District Hospitals, and Federal Medical Centres across Nigeria.

Ghana Hub

NIHR Global Health Research Unit on Global Surgery @Ghana Hub

TThe Ghana Hub is hosted by the School of Medicine, University for Development Studies, Tamale, and the Tamale Teaching Hospital, Tamale.


Tamale Teaching Hospital is the tertiary referral centre for the Northern part of Ghana. It serves the five northern regions of Ghana (Northern Region, Savanah Region, North East Region, Upper East Region, and Upper West Region) with a total population of 5,203,838. The School of Medicine, University for Development Studies, and Tamale Teaching Hospital are sited in the Tamale metropolis. The metropolis has an estimated population of 612,000.

The northern regions of Ghana have 23% urban with the rest of the population in scattered rural communities. The poverty incidence amongst these regions of Northern Ghana is high. Most of the districts in the northern part of Ghana have poverty incidence higher than the national average. Healthcare in Northern Ghana as compared to the rest of the country is deprived. Inadequate health professionals coupled with poor health infrastructure has deprived the northern sector of needed healthcare.

Establishing the NIHR-Global Surgery Unit, Ghana Hub in Tamale comes to add up to strengthening the healthcare infrastructure in northern Ghana. In a unique way, the north which is seen as deprived in many ways is a lead in networking the entire nation in surgical research.
