What factors influence the average length of stay among stroke patients in a Nigerian tertiary hospital?

Introduction: Increased emphasis is being laid on ensuring that health resources are efficiently utilized, especially in resource-constrained settings such as in Nigeria. One of the main indices of how efficiently a health institution is being run is Length of Stay (LOS), which is likely to be higher in chronic diseases such as stroke and diabetes. Stroke is a chronic disease that is currently on the rise in Low and Middle income countries (LMICs) who are also characterized by constraint of health resources. This study seeks to determine the LOS of stroke patients as well as factors that affect it.

Methods: A retrospective analysis of health records of stroke victims admitted into the medical wards of the University College Hospital, Ibadan between January 2012 and December 2014 was conducted. Data on sociodemographic information, comorbidities and risk factors were extracted while LOS was calculated by counting the number of days the patient was admitted. Analysis was carried to using SPSS.

Results: A total of 143 records were used in the final analysis with 53.1% of them being males and having a mean age of 61.5 ± 14.2 years. More than half (53.8%) of the cases were ischemic strokes. The average length of stay was 13.7 ± 8.9 days while bivariate analysis showed that a greater proportion of cases who consumed alcohol, had diabetes and hypertension had LOS of over 7 days than those who did not. However, these differences in proportions were not statistically significant (0.310<<0.883).

Conclusion: LOS of stroke patients in Nigeria was shown to be prolonged especially when compared to similar settings in West Africa. The high prevalence of some of the risk factors of stroke such as diabetes mellitus indicates that policy and advocacy to drive changes in lifestyle are necessary to reduce the incidence of stroke and its consequent burden on health systems.
