Synopsis: 

The trend of accelerating population ageing worldwide heralds new challenges for healthcare policy makers tasked to identify and meet population health and social service (HASS) needs. This thesis therefore aims to develop a HASS need based population segmentation tool which assists policy makers responsible for evaluating and developing HASS interventions designed to meet population needs. A systematic review was first conducted to determine if suitable tools exist and can be adopted for use in a Singapore context. As no suitable tools were found from the systematic review, work on developing and validating a novel instrument known as the Simple Segmentation Tool (SST) commenced. Prospective validation studies of the SST in the inpatient, outpatient and community settings demonstrated inter-rater reliability, convergent validity and predictive validity of the instrument for adverse medical outcomes. Next, normative health and social services for SST defined population segments were created through group consensus of an expert panel. The defined norms were then incorporated into an algorithm which produces indicated health and social services based on SST patient profiles, thus matching services to needs. The SST is therefore ready for use by policy makers interested to assess and segment populations based on HASS needs.
