Abstract
Two hours of travel time specified by the World Health Organization (WHO) to access quality health services is among the most important criteria for the Universal Health Coverage. However, locations of health facilities (HF) in many developing countries fail to realise this target due to a lack of appropriate models considering the local environment. This work used the central-place theory to explore locations of HF in Kishapu and their accessibility status based on two means of transport in the AccessMod tool: walking only and the combination of walking-and-motor devices. The results of the walking scenario indicated that the travel times to the health centres and hospitals exceeded 2 h, and a direct relationship existed between the facility level and the travel time spent to access it. The combined transport (walking and motorized) showed that dispensaries are easily accessible (14.5 min) compared to health centres (42.8 min) and hospitals (67.3 min). To address the challenge, we have developed a model revealing optimal sites with quick access for HF construction and improvement using Multi-Criteria-Evaluation and Analytical-Hierarchy Process methods weighting five criteria including distance from settlements (44% weight), roads (26% weight), existing health facilities (16% weight), rivers (9% weight) and railway (5% weight). A test of the model with both means of transport shows that at all places proposed to be optimal allow patitents to travel in less than 2 h, indicating that the proposed model can effectively and efficiently solve the challenge of allocating HF in society.
