Abstract

Objective: Hospitalisation for hypertension continues to rise in Ghana. It has been revealed that in Ghana, patients hospitalised for hypertension spend between 1 and 91 days on admission. This study therefore sought to estimate the hospital length of stay (LoS) of hypertensive patients and individual or health-related factors that may influence the hospitalisation duration in Ghana.

Methods: We employed a retrospective study design that used routinely collected health data on hospitalised hypertensive patients in Ghana from the District Health Information Management System database between 2012 and 2017 to model LoS using survival analysis. The cumulative incidence function for discharge stratified by sex was computed. To investigate the factors that influence hospitalisation duration, multivariable Cox regression was used.

Results: Out of a total of 106 372 hypertension admissions, about 72 581 (68.2%) were women. The mean age of the patients was 55.3 (SD=17.5) years. Overall, the median LoS was 3 days with almost 90% of all patients being discharged by the 10th day of admission. Patients admitted in Volta region (HR: 0.89, p<0.001) and Eastern region (HR: 0.96, p=0.002) experienced late discharge as compared with patients admitted in Greater Accra. It was revealed that women (HR: 1.09, p<0.001) were discharged earlier than men. However, having a surgical procedure (HR: 1.07, p<0.001) and having comorbidities such as diabetes (HR: 0.76, p<0.001) and cardiovascular diseases other than hypertension (HR: 0.77, p<0.001) increased the LoS of patients.

Conclusion: This study provides the first comprehensive assessment of factors influencing hospitalisation duration of admissions due to hypertension in Ghana. Female sex, all regions except Volta region and Eastern region, experienced early discharge. However, patients with a surgical intervention and comorbidity experienced late discharge.
