'Hybrid Survey' approach to non-communicable disease surveillance in the US-Affiliated Pacific Islands.

ABSTRACT

In 2010 the US-Affiliated Pacific Islands (USAPI) declared a regional state of health emergency due to the epidemic of non-communicable disease (NCD) and an NCD monitoring and surveillance framework was developed that includes adult NCD risk factor and disease prevalence indicators to be collected every 5 years using a population-based survey. On evaluation of existing data from adult population-based NCD surveys, it was found that there was a lack of valid, available and consistently collected data. Therefore, a new model was developed to combine various indicators and survey tools from different partner agencies into one survey. After the report was endorsed by local health leadership, a dissemination workshop was conducted. In 2015 (baseline for Hybrid Survey implementation), three out of nine jurisdictions (33.3%) had completed a population-based survey in the past 5 years. Four (44.4%) had no adult prevalence data at all, two (22.2%) had data sets from their surveys and four (44.4%) had at least two surveys ever collected that could be used for comparison. As of 2020, all nine jurisdictions have, or are in the process of completing an adult population-based survey. Eight (88.9%) have data sets from their surveys, and five (55.6%) have at least two surveys collected that can be used for comparison. This Hybrid Survey model has helped to improve adult NCD surveillance in the USAPI by more efficiently using limited resources. This model could be considered in other small island nations, or rural areas where adult NCD surveillance is challenging.
