Our aim was to analyze patterns and risks of hospitalizations in a large cohort of hemodialysis patients treated in 22 outpatient clinics all over Saudi Arabia (KSA).


The study included all patients admitted at Davita-KSA clinics to continue hemodialysis treatment during the period from October 2014 to December 2018. Overall and cause-specific hospitalization rates were calculated by dividing the number of hospitalizations by the cumulative period of follow-up. Logistic regression was performed to identify factors predisposing to hospitalization.


3508 patients were included (1897 males, 1611 females) with a mean age of 52.5 ± 16.9 years. During a cumulative follow-up period of 5584 years, 1576 hospitalizations were recorded in 26.1% of included patients, 38.7% of them had repeated admissions. Infectious causes, including those related to vascular access, accounted for 34.1% of all recorded hospital admissions vs. 18.8% for cardiovascular complications.
The overall hospitalization rate was of 28.2 % patient-years with an annual duration of 3.4 days per patient. Infectious complications, not related to vascular access, accounted for the highest cause with an annual rate of 6.73 % vs. 5.32% for cardiovascular causes and 4.83% for hospitalizations attributed to vascular access creation and complications.
The median length of hospital stays 11.5 days (range: 2-244 days) with an annual rate of 3.39 days per patient. This rate ranged from 0.05 for hospitalizations related to vascular access to 0.70 and 0. for infectious causes.
Predictors of hospitalization were: Female gender (RR: 1.34, 95%; CI: 1.15-1.56), Age ≥ 65 years (RR: 1.32, 95% CI: 1.11-1.58); time on dialysis (RR: 1.44 per year, 95% CI: 1.34-1.55) diabetic nephropathy (RR: 1.61, 95% CI: 1.38-1.89), and Catheter as vascular access (RR: 1.38, 95% CI: 1.17-1.63)). Among all these factors, Diabetic nephropathy predisposed to a prolonged hospital stay.


Infectious complications were the leading cause of hospitalization among our hemodialysis patients and resulted in the longest hospital stay. Female gender, Age ≥ 65 years, Diabetic nephropathy, Catheter as vascular access and, time on dialysis were found as predisposing to hospitalization but only diabetic nephropathy is associated with prolonged hospitalization.
