Abstract
Social disconnectedness contributes to adverse health outcomes, yet how patterns of change in social disconnectedness are associated with healthcare utilization and costs in Singapore remains underexplored. Data from a longitudinal population health survey were linked with an institutional administrative database. Four patterns of change in social disconnectedness were derived from social isolation (Lubben Social Network Scale-6) and loneliness (three-item UCLA Loneliness Scale) statuses measured at two annual waves. Healthcare utilization and cost outcomes were extracted for 1- and 3-year (cumulative) after wave 2. Participant characteristics at wave 1 formed the baseline and were compared using Chi-square or Kruskal-Wallis tests. The associations between change patterns and subsequent healthcare utilization and costs were respectively examined using two-step hurdle models, adjusting for covariates. Persistent social disconnectedness (16.9% out of 1182 participants) was associated with increased odds of hospitalizations and emergency department (ED) visits and costs, and polyclinic visits, at both follow-ups, compared to participants who remained socially connected (56.7%). Participants who became socially connected (15.2%) exhibited higher odds of hospitalization at 3-year follow-up and higher odds of ED visits and costs at both follow-ups. Among public healthcare users, promoting social connectedness may help reduce costly hospitalizations and ease resource strains on polyclinic services.
