(P-137) Predictors of Length of Stay, Mortality and Outcomes Among Hospitalised COVID-19 Patients In saudi Arabia

Background: COVID-19 pandemic is a major strain on health and economic systems, with rapidly increasing
demand for in patients’ facilities.

Objectives: This study aimed to identify the predictors of mortality and length hospital of stay in COVID-19 patients.

Methods: A retrospective cross-sectional study was conducted at Al-Noor Specialist Hospital in
Mecca, Saudi Arabia. All patients had a confirmed COVID-19 diagnosis by a real-time polymerase
chain reaction (PCR). Descriptive statistics were used to describe patients’ demographic
characteristics, laboratory findings, and clinical outcomes. Logistic/linear regression analysis was
used to identify predictors of death and length of stay at the hospital.

Results: The mean age was 48.0 years (SD: 15.6 years). More than half of the patients (68.5%; n=
292) were males. The median duration of stay at the hospital was 6.0 days (IQR: 300 – 10:00) The
prevalence rate of VTE among the patients was 3.0% (n= 21). In the logistic regression analysis, Age
(OR: 1.06; 1.04 – 1.08), low Oxygen saturation SPO2 (OR: 2.63; 1.46 – 4.73), D.dimer > 0.5 (OR:
8.47; 4.48 – 16.01), ESR > 10 mm/h (OR: 2.89; 1.53 – 5.42), Ferritin > 400mcg/L (OR: 3.89; 2.19 –
6.91), and Procalcitonin > 0.5ug/L (OR: 5.58; 1.66 – 18.77) were associated with a higher risk of death
among patients with COVID-19. Patients with pneumonia (OR: 2.35; 1.19 – 4.61), and patients with
VTE (OR: 17.54; 6.90 – 44.61) were at higher risk of death due to COVID-19.

Conclusions: Hospitalised COVID-19 patients have multiple negative consequences in terms of their
laboratory findings, signs and symptoms. Age and chronic conditions have significant impact on the
mortality rate and the length of hospital stay among COVID-19 patients.
