Background: Stroke is one of the most common noncommunicable diseases, with significant public health implications both globally and in Malaysia. The aim of this study was to evaluate post-stroke survivability as well as the major drug classes prescribed for hospitalized stroke patients.
Methods: A 5-year retrospective study was carried out on the survival of stroke patients admitted to Hospital Seberang Jaya, a main stroke center in the state of Penang, Malaysia. Patients admitted for stroke were first identified using the local stroke registry database, and their medical records were then accessed for data collection, which included demographic information, comorbid conditions, and medications prescribed during admission.
Results: The Kaplan-Meier overall survivability analysis performed indicated 50.5% survival for the duration of 10 days (p < 0.001) post-stroke. Ten-day survivability differences (p < 0.05) were observed for the categories of type of stroke (ischemic stroke (60.9%) and hemorrhagic stroke (14.1%)); stroke episodes (first (61.1%) and recurrent (39.6%)); anti-platelets (prescribed (46.2%) and not prescribed (41.5%)); statins (prescribed (68.7%) and not prescribed (28.1%)); anti-hypertensive (prescribed (65.4%) and not prescribed (45.9%)); and anti-infectives (prescribed (42.5%) and not prescribed (59.6%)) respectively. Higher risks of mortality were observed among patients with hemorrhagic stroke (HR: 10.61, p = 0.004); with 3 or more comorbidities (HR:6.60, p = 0.020); and not prescribed with statins and anti-diabetic. Patients prescribed anti-infectives, on the other hand, had a higher risk of mortality when compared to patients who did not receive anti-infectives (HR: 13.10, p = 0.019). The major drug classes prescribed for stroke patients were antiplatelet drugs (86.7%), statins (84.4%), and protein pump inhibitors (75.6%).
Conclusion: The findings of the study are intended to encourage more non-stroke hospitals in Malaysia to increase their efforts in treating stroke patients, as early treatment can help reduce the severity of the stroke. With the incorporation of evidence-based data, this study also contributes to local data for comparison and improves the implementation of regularly prescribed stroke medication.
