Hub-and-Spoke Stroke System: Enhancing Acute Ischemic Stroke Care in the Philippines

The Hub-and-Spoke stroke system seeks to enhance the efficiency of stroke care by establishing a cohesive network between healthcare facilities providing quality stroke care to patients. This study endeavors to evaluate the effectiveness and characterize the outcomes of acute ischemic stroke patients treated within the Hub-and-Spoke hospital system over 2 years. The assessment focused on thrombolysis rates, mortality, and disability at 3-month follow-up.

We conducted a retrospective single-center review to assess the service delivery and outcomes of acute ischemic stroke patients within the Hub-and-Spoke framework which was implemented in Q3 2021. The Hub-and-Spoke model aimed to provide appropriate neurological care for stroke patients, growing from four to eight spoke hospitals in 2 years.

The study consisted of 132 stroke patients transferred to the hub hospital, and 42 (31.8%) of them had acute ischemic stroke. Among these 42 ischemic stroke patients, 76% of them were candidates for thrombolysis with a mean NIHSS of 12 (6-22). Among the subset of 32 patients eligible for intervention within the specified time window, a total of 23 individuals, constituting 72% received r-TPA. Regarding patients administered r-TPA, 91.2% demonstrated favorable functional outcomes with an mRS score of 0-1, while 8.7% exhibited a score of 2-3. Among those not given r-TPA, the mean NIHSS was 17 (ranging from 2 to 32). Their functional outcomes after 3 months revealed 52.5% with an mRS score of 0-1, 16% with a score of 2-3, 21.2% with a score of 4-5, and 10.5% with an mRS score of 6.

Hub-and-Spoke networks represent a crucial advancement in stroke treatment, particularly for facilities lacking the capacity to manage strokes effectively. By leveraging added expertise and reducing the time from onset to diagnosis to treatment, these networks have significantly enhanced patient care. This enhancement is particularly evident in the increased rate of thrombolysis, resulting in reduced morbidity and prevention of mortality.
