Improving health care attention in remote population poses a challenge for professionals and policy-makers. In those areas, geographical location and high altitude together with the lack of appropriate infrastructure and communication represent life-threatening conditions for people preventing them to reach health outcomes. They constitute a challenge for primary health attention (PHA) everyday activities carried out by community health workers (CHW) also. Public policies need to be informed by data and insights coming from ethnographic research for better understand local practices and ecological factors affecting people?s access and effective use of health services. Moreover, it is necessary to include CMH and professionals? perspectives. Healthcare practices performed by the population of Molinos? district (Salta Province) has been studied from an ethnographic point of view. We described the micro level of people?s cultural and socioeconomic organization, and its impact on people?s interactions with the healthcare system. In that framework, knowledge, decision-making criteria and itineraries materialized in cognitive maps produced by CHW as key actors in PHA became of interest. Based on the results obtained so far, we designed university extension projects in order to improve CHW?s management, sharing and storage of accurate geospatial, demographic, sociocultural and epidemiological data by introducing technological innovations. A mixed methods approach combining interviews, surveys, participatory mapping, and workshops were used.
