Insights
Stroke incidence is rapidly increasing in Bahrain
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- Stroke incidence in Bahrain has nearly doubled over 16 years, disproportionately affecting the Bahraini population.
- The Bahraini stroke demographic is younger and presents with higher rates of diabetes, hypertension, and hyperlipidemia compared to Western populations.
- An aging population combined with prevalent risk factors indicates a significant future increase in stroke cases.
Purpose of the Study:
- To analyze the current trends and risk factors associated with stroke incidence in Bahrain.
- To evaluate the quality of stroke care and risk factor management in Bahrain.
- To identify areas for improvement in stroke prevention and treatment.
Main Methods:
- Retrospective analysis of stroke incidence and patient demographics in Bahrain.
- Comparison of Bahraini stroke patient data with Western cohorts.
- Assessment of hospital-based stroke care practices, including diagnostic imaging, medication, and acute treatment protocols.
Main Results:
- Stroke incidence in Bahraini nationals is significantly higher (110/100,000) than in non-Bahrainis (27/100,000).
- Bahraini stroke patients are, on average, 10 years younger than their Western counterparts, with high comorbidity rates (Diabetes 54%, Hypertension 75%, Hyperlipidemia 34%).
- While timely diagnostics (88% scanned within 24h) and aspirin administration (86% within 48h for non-hemorrhagic stroke) were common, no patients received thrombolysis or were admitted to a stroke unit.
Conclusions:
- Urgent implementation of evidence-based strategies is crucial to mitigate the rising stroke burden in Bahrain.
- Improving primary care for risk factor management and establishing stroke units with thrombolysis capabilities in secondary care are essential.
- Targeted interventions addressing high-risk factors in the Bahraini population are needed to prevent a worsening 'ticking time bomb' scenario.
Abstract:
The incidence of stroke in Bahrain is rising in the Bahraini population and has nearly doubled over the last 16 years, while the incidence in the non-Bahraini population has not changed. Incidence of stroke in the Bahraini population (110/100,000) is now much greater than in the non-Bahraini population (27/100,000). The Bahraini stroke population is 10 years younger than Western comparators with a much higher prevalence of many of the risk factors for stroke, including diabetes (54%), hypertension (75%) and hyperlipidemia (34%). The combination of an ageing Bahraini population alongside a high prevalence of risk factors suggests a 'ticking time bomb' that is likely to see a continuing rise in the incidence of stroke. The quality of risk factor prevention and hospital-based stroke care is therefore crucial in Bahrain. While 88% of patients were scanned within 24 h and 86% with non-haemorrhagic strokes were commenced on aspirin within 48 h, none of the patients received thrombolysis or were admitted to a stroke unit. Improvement of stroke outcomes in Bahrain could be achieved through implementation of evidence-based measures, including improved risk factor management in primary care and stroke units and thrombolysis in secondary care.
