Background: Access to healthcare can be defined as opportunity or ease for patients to come to the services, while accessibility can be defined as the potential or ease for certain health services or health facilities to be reach and utilized by the patients. Spatial accessibility is assessment of accessibility determinant which can be segregated according to geographical location. The aim of this manuscript is to identify spatial accessibility assessments methods used in the primary healthcare accessibility studies within rural population setting and integration with its determinants. Materials and Methods:Scoping systematic review was done using public domain search engine. Keywords used for article search are Spatial Accessibility; Geographical Accessibility; Primary Health Care; Primary Care; Rural; Non-Urban and Remote. All articles within 15 years of publication were included with the exclusion criteria of review article, research methodology protocol and non-English articles. After screening, 10 final articles were eligible for qualitative synthesis. Content analysis was carried out, then synthesized into location of study, purpose of the study, method of spatial accessibility assessment and accessibility determinants. Result:Most of the studies in this review used gravity method (floating catchment method), three studies using physician population ratio and one study used travel impedance. Travel impedance and physician population ratio were described descriptively, which later were correlated with utilization and mortality. Several aspatial factors were also been associated with spatial accessibility through correlation, integration through formula calculation, aggregation in index and overlaying through geographical information system.Conclusion: Development of geographical information system has made more studies to use floating catchment method as a tool to assess spatial accessibility. Alteration to existing floating catchment method to allow researcher to address limitation for its predecessor. Recent development also integrates spatial accessibility with aspatial factor and its determinants. This knowledge will facilitate policy maker to improve the accessibility by overcoming the barriers.

Introduction: A huge number of Orang Asli population live in isolated area within peninsular Malaysia. Their lack of proper road and remoteness made their access to healthcare services difficult. Batang Padang has the 22800 Orang Asli reside in the district. Primary healthcare services have been provided to this population through static clinic and mobile clinic.Objective: This study was done to determine distance of primary healthcare from Orang Asli village and their correlation with primary healthcare utilization.Methods: A cross sectional study using Geographical Information System was done using spatial data from various sources for mapping and spatial analysis. Network analysis using ArcGIS software was used to determine the distance while Spearman correlation was used to determine association between distance and primary healthcare utilization.Result: Most of Orang Asli villages located not far from main road. Mean distance from Orang Asli village to nearest primary healthcare clinic is 5.87 kilometers. Mean duration taken for Orang Asli to come to the primary healthcare clinic is either 4.71 minutes by land transportation or 70.42 minutes by walking. Orang Asli villages located in the center of the district around Bandar Tapah have short distance to primary healthcare and the distance increase as the villages located away from the center. There is significant correlation between network distance with Orang Asli attendance to clinic (r 0.203) and MMR vaccination (r 0.230). There is also significant correlation between walking duration with Orang Asli attendance to primary healthcare (r 0.178) and MMR vaccination (r 0.227).Conclusion: As the distance and duration increase for Orang Asli to get to primary healthcare, there is increase need of primary healthcare services. Planning of primary healthcare for Orang Asli should consider the distance from these villages to primary healthcare services.International Journal of Human and Health Sciences Supplementary Issue: 2019 Page: 46
