Mortality of patients hospitalized in the Rheumatology Department of the Bogodogo University Hospital, Burkina Faso: frequency and associated factors

---

Résumé

Context and objective. Little is known regarding the predictors of mortality in rheumatic patients. The aim of the present study was to determine the frequency and factors associated with death in patients hospitalized in the Rheumatology Department of the Bogodogo University Hospital. Methods. This was a retrospective descriptive and analytical study from January 2023 to June 2023. Patients admitted to the hospital were followed. The variables of interest were death, duration of progression of symptoms before hospitalization and duration of hospitalization. Survival function was estimated using the Kaplan-Meier method. Cox regression analysis was used to model the factors associated with death. This analysis provided the adjusted hazard ratios. Results. One hundred and three patients were included in the study, and 13 patients died, representing a death frequency of 12.62%. The 120-day survival rate was 71.30%, based on the duration of symptoms before hospitalization. The median survival rate was 45.60% according to the duration of hospitalization. Factors associated with death according to the duration of symptoms before hospitalization were the presence of arterial hypertension (HR=8.43; IC95% [1.96-36.2]; p=0.004), the presence of infectious pathology (HR=6.93; IC95% [1.79-34.81]; p=0.010), and the presence of tumor pathology (HR=9.78; IC95% [2.93-43.68]; p=0.004). Factors associated with death according to length of hospitalization were the presence of diabetes mellitus (HR=7.24; IC95% [1.31-40.1]; p=0.023), a motor deficit (HR=7.11; IC95% [1.07-47.0]; p=0. 042), infectious pathology (HR=2.01; IC95% [1.11-15.69]; p=0.002), tumor pathology (HR=13.70; IC95% [3.9-77.44]; p<0.001), and microcrystalline pathology (HR=2.94; IC95% [1.44-18.74]; p=0.031).Conclusion. The mortality rate in the Rheumatology Department is significant and varies according to the duration of symptoms and length of hospitalization, as well as the associated factors.Received: November 6th, 2024Accepted: April 2nd, 2025
