Low ses, x-fittt 2.0, was offered free of charge to participants, and included 12 weeks of intensive guidance and sports sessions, and 21 months of aftercare. as the impact of care-pa initiatives on healthcare utilisation has not yet been studied, our research question was: ‘what is the impact of participation in a care-pa initiative on the healthcare utilisation of citizens with a low ses?’. methods we studied the healthcare utilisation of 44 former participants of x-fittt 2.0, focussing on general practitioner care, pharmaceutical care, hospital care, paramedical care, medical aids and mental healthcare. we compared utilisation intensity (number of healthcare claims) during the two years before participation in x-fittt 2.0 (period 1) with utilisation intensity during the two years after initial participation (period 2) using paired t-tests. results as expected, utilisation intensity increased significantly for paramedical care for non-chronic disorders after participation. no differences in utilisation intensity were observed for the other healthcare categories. furthermore, although it was not the core focus of this study, our results show that people with a low ses tend to have higher healthcare utilisation than those with a higher ses. conclusions this exploratory study, which is unique for its use of healthcare claims data for participants of a care-pa initiative, shows a statistically significant increase in utilisation intensity for paramedical care (supplementary healthcare insurance for non-chronic conditions) in period 2 compared with period 1, as expected. this increase is likely caused by a greater utilisation intensity for physiotherapy, which covers respec- tively 95% and 92% of the paramedical healthcare claims of the supplementary healthcare insurance in periods 1 and 2. the design of our study can be used as a template for future
