Abstract

Background: Stroke ranks as the second leading cause of mortality worldwide, following ischemic heart disease, and is expected to maintain this position through 2030. This neurological ailment is profoundly impactful, imposing a significant burden on health and the economy. In 2019 alone, it was responsible for 6.6 million fatalities and the loss of 143 million disability-adjusted life years (DALYs) across the globe.

Objectives: This study highlighted the prevalence and pattern of admission mortality among acute stroke patients managed over 9 years in a private tertiary hospital in Abakaliki, Nigeria.

Methodology: This was a retrospective hospital-based study conducted at a tertiary hospital in Abakaliki, Nigeria from January 2014 to December 2022. Relevant data were extracted from the patients' case notes and the sociodemographic, clinical and laboratory parameters of acute stroke survivors were compared with those of their dead counterparts.

Results: Out of the 172 (males - 57%; females - 43%) patients that fulfilled the inclusion criteria, 53 (30.81%) had haemorrhagic stroke while 119 (69.19%) had ischaemic stroke. The overall admission mortality rate was 15.12%, and it was more common in patients with haemorrhagic stroke, advancing age, severe hypertension, severe stroke, impairment of consciousness, renal dysfunction, hypernatremia, neutrophilic leucocytosis, and short admission duration.

Conclusions: High mortality rates are linked to acute stroke admissions, particularly in cases involving haemorrhagic stroke, increasing age, severe hypertension, substantial stroke severity, impaired consciousness, renal dysfunction, hypernatremia, neutrophilic leukocytosis, and brief admission duration.
