| Summary: | Knowing the typical length of hospital stay of COVID-19 patients and which factors affecting the stay time is important for hospital management. 3184 COVID-19 patients from the Tokat State Hospital collected from were examined on arrival to the hospital and were either treated as inpatients, or as outpatients. By using simple, conditional and cause-specific Cox proportional-hazard regressions for competing risk, we examined factors impacting hospital stay time, both overall and by taking into account patient’s age or survival status and contribution from a factor to the rate of event of mortality, and to the event of discharge. Surviving ICU patients have longer hospital stay time than non-surviving ICU patients, which is longer than non-ICU patients. Older age is correlated with a longer hospital stay. Increased C-reactive protein (CRP), decreased hemoglobin (HGB) and calcium levels are associated with longer hospital stay, independent from the contribution from surviving status. Almost all factors we collected contribute to a faster/slower mortality or discharge rate. We also observed that glucose is more important than HbA1C or diabetes status in its influence on hospital stay time. This information could be used for a better hospital bed management.
