[Spatial variation of hypertension treatment coverage in the municipality of Santiago, Chile].

One of the tasks of primary health care is to achieve adequate treatment coverage for patients with arterial hypertension. The aim of this study was to analyze the spatial variation of hypertension treatment coverage in the municipality of Santiago de Chile in 2014, evaluating its relationship with the distance to primary health care establishments and socioeconomic factors using georeferencing techniques and global and geographically weighted Poisson regression models. According to the results, arterial hypertension treatment coverage shows spatial dependence, given that its relationship with the presence of older adults, the proportion of population enrolled, socioeconomic status and the distance to primary health care establishments varied spatially. It is concluded that in order to improve hypertension coverage it is necessary to consider different local realities, a process that can be facilitated by the application of spatial analysis techniques.
