Timeliness of acute stroke care and predictors of delays in three referral hospitals in Douala, Cameroon: a multicenter cross-sectional study
This multicenter cross-sectional study of 126 patients in Douala, Cameroon, reveals substantial delays in acute stroke care across prehospital arrival, neurological assessment, and imaging, with delays primarily driven by patients' failure to recognize stroke symptoms as urgent and their initial presentation at non-specialized healthcare facilities.

Stroke is a sudden medical emergency where blood flow to part of the brain is blocked or a blood vessel bursts, causing brain cells to die. Because the brain controls everything from movement to speech, the damage can be permanent and life-altering. The medical community has long known that time is the most critical factor in treating this condition. The faster a patient receives care, the more brain tissue can be saved. This principle has led to the development of specific treatments that can dissolve clots or mechanically remove them, but these therapies only work if given within a narrow window of time, usually a few hours after symptoms first appear. In many parts of the world, getting a patient to a hospital quickly enough to use these treatments remains a significant challenge, often due to a lack of awareness about what a stroke looks like or difficulties in reaching specialized medical centers.
In a recent study, researchers investigated how long it takes for stroke patients to receive care in Douala, Cameroon, and what causes the delays. The team looked at 126 adults who had been admitted to three major referral hospitals in the city with confirmed strokes. They tracked the journey of each patient through three specific stages: the time from when symptoms started until the patient arrived at the hospital, the time from arrival until a neurologist examined them, and the time from arrival until a brain scan was completed. The researchers defined a delay as arriving at the hospital more than four and a half hours after symptoms began, waiting more than an hour to see a specialist, or waiting more than twenty-five minutes for a scan.
The results revealed that delays were widespread at every stage of the process. The typical patient arrived at the hospital more than sixteen hours after their symptoms first started, meaning the vast majority missed the critical window for the most effective emergency treatments. Once inside the hospital, the wait for a specialist was also long; nearly ninety percent of patients waited more than an hour to be seen by a neurologist. Similarly, most patients waited longer than the recommended twenty-five minutes to get their first brain scan. The study found that the type of hospital a patient first visited and how they perceived their own symptoms were the main reasons for the long wait to get to the hospital. Patients who did not realize their symptoms were an emergency, or who first went to a clinic without a neurology department, were significantly more likely to arrive late.
Inside the hospital, the type of brain scan used influenced how quickly a specialist could evaluate the patient. Those who underwent magnetic resonance imaging, a detailed scan that takes longer to perform, waited significantly longer to see a neurologist compared to those who received a standard computed tomography scan. Additionally, patients with ischemic strokes, caused by a blockage, waited longer for their imaging than those with hemorrhagic strokes, which are caused by bleeding. The researchers concluded that the biggest hurdles to saving brain tissue in this region are not just the distance to the hospital, but the failure to recognize the urgency of the symptoms and the tendency to seek help at facilities that cannot provide immediate, specialized care. These findings highlight that improving stroke outcomes requires not just better hospitals, but also better education for the public and clearer pathways to get patients directly to the right experts.
