Epidemiology of Morbidity and Mortality of COVID-19 Patients During the Period of June 2020-September 2021 in Sulianti Saroso Infectious Disease Hospital, Indonesia.

Abstract

Objectives: The increasing mortality rate of COVID-19 has remained an international public health concern. Limited studies on clinical treatment and morbidity in hospital settings are available in Indonesia. This present study aims to analyse demographic characteristics, clinical signs and treatment in COVID-19 patients and their association to the mortality case in Sulianti Saroso Infectious Disease Hospital.

Methods: The study applied a retrospective cohort approach to all COVID-19 inpatients confirmed by polymerase chain reaction (PCR) testing in Sulianti Saroso Infectious Disease Hospital from 1 June 2020 to 30 September 2021. Overall survival rates until the end of the study were calculated using the Kaplan-Meier method and compared using the log-rank test. A Cox regression model was used to evaluate the crude and adjusted hazard ratios for associated factors.

Results: We collected 1,970 inpatient data that met our inclusion and exclusion criteria. Most of them were 19 years old-59 years old (73.2%) and male (52.6%), and 966 (49%) patients had comorbidities. Approximately 63.9%, 89.2%, 89.8%, 82%, and 14.1% of the patients had ferritin levels ≤ 800, received antiviral treatment, were treated in non-intensive wards, had a moderate or mild clinical stage and did not survive, respectively. In the adjusted analysis, mortality was associated with sex (hazard ratio [HR]: 1.12; 95% CI: 1.02, 1.23), presence of comorbidity (HR: 1.19; 95% CI: 1.08, 1.30) and favipiravir (FPV) plus azithromycin treatment (HR: 1.21; 95% CI: 1.06,1.39). FPV treatment (HR: 1.35; 95% CI: 1.04, 1.75) was associated with higher mortality.

Conclusion: Tailored approaches to treatment, considering individual risk factors and comorbidities, are crucial in improving patient outcomes.
