RESUMEN
Introduction: there is a paucity of data on the epidemiology of COVID-19 infection in Cameroon with a few studies limited to big urban cities. The objective of this study was to describe the clinical characteristics and outcomes of hospitalized patients with COVID-19 at the Buea Regional Hospital, in the South West region of Cameroon. Methods: this was a retrospective cross-sectional study. The medical records of hospitalized patients with COVID-19 were reviewed from 2020 to 2021. Hospitalized patients with laboratory-confirmed COVID-19 were included. Binary logistic regression was used to identify factors associated with mortality. Results: two hundred and ten (210) patients were included in this cohort. There were 114 (54.7%) men. The mean age was 60±17.1 years. The common co-morbidities were hypertension (46.7%), diabetes mellitus (31%), and HIV infection (5.7%). The most common symptoms were dyspnea (93.3%), fatigue (93.8%), cough (77.6%), and fever (71.4%). The median oxygen saturation was 85% and the median respiratory rate was 24 cycles per minute. More than 80% had crackles on lung examination. Death occurred in 57 (27.1%) patients. In binary logistic regression, the factors independently associated with mortality were heart failure (aOR: 6.7, p=0.034), SBP < 100 mmHg (aOR: 8.1, p<0.001), RR > 24 cpm (aOR: 3, p=0.016), SaO2<90% (aOR: 6.2, p=0.031), blood glucose > 150mg/dL (aOR: 3.3, p=0.02), and CRP > 50 mg/L (aOR: 3.3, p=0.036). For every 1 mg/dL rise in blood glucose, the odds of death increased by 1% (p=0.011). For every 1 mg/L rise in the C-reactive protein (CRP), the odds of death increased by 1% (p=0.054). Conclusion: over half of hospitalized patients with laboratory-confirmed COVID-19 infection in the South West Region of Cameroon were males. Hypertension and diabetes were common co-morbidities. More than a quarter of these patients died. Furthermore, having heart failure, low systolic blood pressure (SBP), low oxygen saturation, elevated respiratory rate, high CRP and blood glucose levels on admission were associated with poor prognosis.
