Background: African countries with limited healthcare capacity are particularly vulnerable to the novel coronavirus. The pandemic has left health systems short on resources to safely manage patients and protect health care workers. South Africa is still battling the epidemic of HIV/AIDS and tuberculosis which have had their programme/services interrupted due to the effects of the pandemic. Lessons learned from the HIV/AIDS and TB programme have shown that South Africans delay seeking health services when a new disease presents itself.
Objective: The study sought to investigate the risk factors for COVID-19 inpatients' mortality within 24-hours of hospital admission in Public health facilities in Limpopo Province, South Africa.
Methods: The study used retrospective secondary data obtained from the 1 067 clinical records of patients admitted between March 2020 and June 2021 by the Limpopo Department of Health (LDoH). A multivariable logistic regression model, both adjusted and unadjusted, was used to assess the risk factors associated with COVID-19 mortality within 24 hours of admission.
Results: This study, which was conducted in Limpopo public hospitals, discovered that 411 (40%) of COVID-19 patients died within 24-hours of admission. The majority of the patients were 60 years or older, mostly of female gender and had co-morbidities. In terms of vital signs, most had body temperatures less than 38°C. Our study findings revealed that COVID-19 patients who present with fever and shortness of breath are 1.8 and 2.5 times more likely to die within 24-hours of admission to the hospital, than patients without fever and normal respiratory rate . Hypertension was independently associated with mortality in COVID-19 patients within 24-hours of admission, with a high odds ratio for hypertensive patients (OR = 1.451; 95% CI = 1.013; 2.078) compared to non-hypertensive patients.
Conclusion: Assessing demographic and clinical risk factors for COVID-19 mortality within 24-hours of admission aids in understanding and prioritising patients with severe COVID-19 and hypertension. Finally, this will provide guidelines for planning and optimising the use of LDoH healthcare resources and also aid in public awareness endeavours.
