ABSTRACT

The study was aimed at the geospatial analysis of Primary Health Care facilities in Warri Metropolis. The study adopted GIS methodology to carry out the study. The objectives included design of a spatial database, acquisition of both primary and secondary datasets, creation of a spatial database and spatial analyses were carried out to generate results for a Decision Support System. Spatial database was designed and created. Vector data model was adopted for the study where the Primary Health Centres were represented as points, the roads as polylines while the buildings footprints, water bodies, swamps and the boundary of the study area were represented as area (polygon) shapes. The results generated showed that there were Twenty Eight PHCs within the study area with fourteen each in Uvwie and Warri South Local Governments. The distribution pattern exhibited by the PHCs was random without any clustering or dispersal. The Nearest Neighbour Ratio according to the summary is 1.062096 while the z-score and p-score were respectively given as 0.628596 and 0.529613. The study also showed that forty one thousand, one hundred and sixty seven (41,167) buildings were adequately served by the PHCs within the study area. This represents 94.87% of total buildings (43,393) in the study area while those outside the buffer zones were 2226 buildings representing 5.13% of the total and can attend a primary health centre closest to them. The study was concluded having achieved the aim and the objectives and recommendations made in line with the findings.
