Hospital Length of Stay and Related Factors for COVID-19 Inpatients Among the Four Southern Regions Under the Proposed Southern Business Unit of Saudi Arabia

Abstract

Objective To assess the length of stay (LoS) variation for COVID-19 inpatients among the four regions of the Southern Business Unit (SBU). Methods This is a comparative retrospective study of the LoS of COVID-19 inpatients in the four regions of the SBU in the KSA. Data was collected from the Ministry of Health (MoH) in all hospitals in the SBU. Participants were all patients admitted with confirmed COVID-19 between March 2020 and February 2021. Variables included region (variable of interest), demographics, comorbidities, and complications. Multilinear regression was performed to control for any factors that might have had an association with LoS. Results The mean LoS of the total sample was 10 days and Bisha (the reference) was 7 days. Compared to Bisha, LoS in Jazan was 34% longer, in Najran 62% longer, and Aseer 40% longer. We observed that other factors also had an association with LoS, compared to Bisha, compared to the references, Saudi patients had a 15% shorter stay; admission to ICU increased LoS by 57%; patients who died during hospitalization had a 39% shorter LoS; the complications from COVID-19 of acute kidney injury and ARDS increased LoS by 22% and 48% respectively. Conclusion After statistically controlling for confounders, this study reveals that LoS was significantly impacted by region in the SBU in the KSA. We recommend that further study be conducted to illuminate the underlying causes of this variation which may be organizational or structural to ensure high quality of care, access to care, and equity of resources throughout all regions of the SBU in accordance with the new Model of Care in Vision 2030.

Length of Stay Analysis of COVID-19 Intensive Care Unit Admissions Using Count Regression and Hurdle Regression Models: A Study in a Tertiary Hospital, Cape Town, South Africa

“…Similar studies elsewhere also identified diabetes mellitus (23.6%), hypertension (22.5%), and cardiovascular disease (3.7%) as common comorbidities in COVID-19 patients (Alimohamadi et al, 2022). However, comparative retrospective studies in Saudi Arabia have shown that comorbidities had no statistically significant correlation with LoS (Alharbi et al, 2022). The study also showed that important clinical biomarkers in COVID-19 patients included creatinine, D-dimer, NT-proBNP and TropT.…”

The pattern of emergency department length of stay in Saudi Arabia: an epidemiological Nationwide analyses of secondary surveillance data

“…Considering that the outcome in this analysis was the overall LOS, further analyses of the more detailed KPIs collected through the Ada'a program, namely, door to doctor, doctor to decision, and decision to disposition, in addition to this overall KPI, will provide the necessary information to develop tools/policies for improvement. We also recommend measuring ED LOS at the cluster level of the business units, as proposed by the new model of care introduced in the healthcare transformation plan of Vision 2030, and at the regional level of the 13 administrative regions of Saudi Arabia (55,56). With highly varying socioeconomic levels among regions, we expected to find regional differences due to these variations.…”

Relationship Between Smoking and the COVID-19 Infection Outcome Among Hospitalized Patients

“…The results of the present study also suggested that the average length of stay upon admission was 6 days (range: 1-68) for inpatients due to a positive COVID-19 test. The average length of stay in studies in Brazil and Saudi Arabia was 10 ± 8 (33) and 10 days, respectively (37). Another study reported the length of hospital stay for deadly cases in the USA, Italy, and Germany was 2-10, 1-6, and 5-19 days, respectively (38).…”
