BACKGROUND. The COVID-19 pandemic has had a significant impact on healthcare systems globally as most countries were not equipped to deal with the outbreak. To avoid complete collapse of intensive care units (ICUs) and health systems as a whole, containment measures had to be instituted. In South Africa (SA), the biggest intervention was the government-regulated national lockdown instituted in March 2020. OBJECTIVE. To evaluate the effects of the implemented lockdown and institutional guidelines on the admission rate and profile of non-COVID-19 patients in a regional and tertiary level ICU in Pietermaritzburg, KwaZulu-Natal Province, SA. METHODS. A retrospective analysis of all non-COVID-19 admissions to Harry Gwala and Greys hospitals was performed over an 8-month period (1 December 2019 - 31 July 2020), which included 4 months prior to lockdown implementation and 4 months post lockdown. RESULTS. There were a total of 678 non-COVID-19 admissions over the 8-month period. The majority of the admissions were at Greys Hospital (52.4%; n=355) and the rest at Harry Gwala Hospital (47.6%; n=323). A change in spectrum of patients admitted was noted, with a significant decrease in trauma and burns admissions post lockdown implementation (from 34.2 - 24.6%; p=0.006). Conversely, there was a notable increase in non-COVID-19 medical admissions after lockdown regulations were implemented (20.1 - 31.3%; p<0.001). We hypothesised that this was due to the gap left by trauma patients in an already overburdened system. CONCLUSIONS. Despite the implementation of a national lockdown and multiple institutional directives, there was no significant decrease in the total number of non-COVID-19 admissions to ICUs. There was, however, a notable change in spectrum of patients admitted, which may reflect a bias towards trauma admissions in the pre COVID-19 era.
