  • Mean follow-up time was—patients with ID with a health check: 560 days (pre), 1081 (post). Patients with ID without a health check: 521 days (pre), 1059 (post).

  • *This represents the within-person change in admission post-health check compared with pre-health check estimated from the conditional Poisson model.

  • †This represents the within-person post-health check change in admissions between the patients with ID and their respective controls (n=46 408 for patients with ID with health check, n=47 622 for patients with ID without health check) estimated from the conditional Poisson model.

  • ‡For definition of ambulatory care sensitive conditions please refer to e-table 4.

  • §Excludes patients with abnormally high elective rates (average >6/year).

  • ACSC, ambulatory care sensitive condition; ID, intellectual disability; IRR, incident rate ratio.
