Longer travel time to healthcare facilities may negatively affect health outcomes [1]. This is particularly crucial if patients are children and need immediate care. The lack of access and distance to health care have been cited as major factors contributing to under-5 mortality and minimal healthcare utilization respectively [2]. A good or reliable access (≤ 60 minutes of travel time) to a healthcare facility is considered crucial for families with children [2]. Access to health facilities, however, is impacted by certain factors such as presence or lack of facilities [3], quality of existing transport infrastructure [4], and availability of a vehicle [4, 5]. In an emergency, for example, the availability of a vehicle plays a critical role, especially in rural and remote areas with lower access to different forms of transportation and often at longer distances from a hospital [6]. The purpose of this study is twofold. First, is to represent geographical accessibility to children’s hospitals by calculating and mapping the 60-minute travel time service areas for individual children’s hospitals in Texas. Spatial or geographical accessibility refers to physical accessibility and is often measured based on driving distance/time using a geographic information system (GIS). Second, is to model the hospital bedpatient ratio for each service area. This study uses the number of hospital beds as a proxy variable of resource availability, considered a primary indicator of healthcare resources in the literature [7].
