Un modelo de áreas pequeñas para la estimación de la frecuencia de consumo de Bazuco al interior de las Unidades de Planeamiento Zonal de Bogotá

Abstract

Health care for people who abuse psychoactive substances involves a significant logistical and operational deployment by the Bogota District Health Secretariat (SDS) to ensure the Epidemiological Field Intervention (IEC) of consumers. To address this situation, the SDS has set up the Epidemiological Surveillance Subsystem for the Abusive Consumption of Psychoactive Substances (VESPA). This subsystem provides technical assistance to those who present abusive consumption of Psychoactive Substances (PAS) and who have been attended in the first instance by the Primary Data Generating Units (UPGD) or Reporting Unit (UI). These facilities are specialized centers for drug dependence care. This study seeks to guarantee temporary estimates of the total number of users in each Zonal Planning Unit (UPZ) through a small area model (Fay Herriot spatial) that allows the SDS to focus attention and surveillance of this phenomenon according to the geographic concentration of the estimated cases, taking into account that the UPGDs do not provide total coverage in the District and neither are all the cases that should be attended captured.
