A single-centre observational cohort study to evaluate volume and severity of emergency general surgery admissions during the COVID-19 pandemic: is there a "lockdown" effect?

Abstract Introduction The COVID-19 pandemic has led to changes in NHS surgical service provision, including reduced elective surgical and endoscopic activity, with only essential emergency surgery being undertaken. This, combined with the government-imposed lockdown, may have impacted on patient attendance, severity of surgical disease, and outcomes. The aim of this study was to investigate a possible ‘lockdown’ effect on the volume and severity of surgical admissions and their outcomes. Methods Two separate cohorts of adult emergency general surgery inpatient admissions 30 days immediately before (16th February 2020 to 15th March 2020), and after UK government advice (16th March 2020 to 15th April 2020). Data were collected relating to patient characteristics, severity of disease, clinical outcomes, and compared between these groups. Results Following lockdown, a significant reduction in median daily admissions from 7 to 3 per day (p Conclusion There appears to be a “lockdown” effect on general surgical admissions with a profound impact; fewer surgical admissions, more acutely unwell surgical patients, and an increase in all cause 30-day mortality. Patients should be advised to present promptly with gastrointestinal symptoms, and this should be reinforced for future lockdowns during the pandemic.
