University of KwaZulu-Natal, Durban.Introduction Severe Acute Respiratory Syndrome Corona Virus 2 (SARS COV 2) is the virus responsible for the COVID -19 (C19) pandemic. South Africa (SA) experienced multiple periods of increased transmission during which tertiary, regional and central hospitals were overwhelmed, resulting in a low acceptance rate of referrals from district hospitals (DHs). Thus, many severely ill, complex patients were managed at DHs while awaiting an Intensive Care Unit (ICU) bed. This study aims to describe mortality trends in a comparative analysis of the first three C19 waves at Wentworth Hospital (WWH). Literature Review Known risk factors for mortality are older age; male sex; Black African, Coloured and Indian compared to white race; admission in the public sector; comorbid diseases and obesity. Waves 2 and 3 had higher mortality rates compared to wave 1. Methods The study is a single-centre retrospective analysis of WWH’s clinical records and included all patients infected with C19 (based on clinical, biochemical or radiological features suggestive of infection) who were admitted and subsequently demised in-hospital during the defined waves. Data was collected using a pre-piloted data extraction tool. Demographic and presenting features of the patients along with investigations and management strategies were compared by the primary investigator across the three waves. Results Wave one, two and three yielded case fatality rates of 14.5%, 27.6% and 6.3%, respectively, and crude fatality rates of 16.7%, 33.0% and 12.2%, respectively. Black Africans were less likely to demise during the third wave (odds ratio (OR) 0.54; 95% confidence interval (CI) 0.31 to 0.94). Obesity was most prevalent in the second wave (OR 1.87; CI 1.01 to 3.46). Patients in the second wave had clinical frailty scores of less than five (OR 2.51; CI 1.56 to 4.03). Severe ground glass appearance on chest radiographs was most common during the second wave (OR 2.37; CI 1.49 to 3.77). Conclusion The beta variant dominated the second wave and was the most virulent, as highlighted by the highest case- and crude fatality rates. This study identified the need to understand if case fatality 2 rates and mortality trends at a DH were significantly higher than those at regional or tertiary hospitals. It is hoped that this study will provide clinical and hospital managers, and provincial and national healthcare policy makers with insight into challenges faced in the health system in the public health sector and allow implementation of improved public health and planning strategies for future pandemics.South African Family Practice JournalType 2 Diabetes MellitusCovid 19Thesishttps://doi.org/10.29086/10413/22731
