Timely transportation for emergency care is critical for stroke patients, and thus accessibility to stroke centers is important. This study identified populations with travel times less than 15, 30, 45, and 60 minutes in the Mid-Atlantic states using network analysis. It found that the Mid-Atlantic had around 85% of total population travel more than 30 minutes to arrive at a stroke center (25% between 30 to 45 minutes, 58% between 45 to 60 minutes, and 1.0% more than 60 minutes). In terms of state-level travel time of the elderly population, 16% of the elderly population in Delaware travels between 30 minutes to 45 minutes and 16% travels between 45 minutes and 60 minutes. In New Jersey, New York, and Pennsylvania, 24% of the elderly population travels between 30 to 45 minutes to stroke centers on average (21% in NJ, 25% in NY, and 26% in PA). Moreover, 60% of the elderly population in these states travels between 45 minutes and 60 minutes on average (65% in NJ, 60% in NY, and 56% in PA). Notably, 2% of the elderly population in New York (70,207) takes more than an hour and 0.3% in Pennsylvania (6,141). New York presents the most need for new stroke centers having the largest population among states in this study and the largest number of the elderly populations with travel time more than an hour. This study result indicates the need of designating new stroke centers and allocating resources in areas with more susceptible populations.
