  • Fully participating practices had >50% of their patients with ID with a health check by end of 2010. Non-participating practices had <25% of their patients with ID with a health check by end of 2012. Ninety-five practices did not meet either criteria and were excluded from the comparison.

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

  • †This represents the within-practice post-health check change in admissions between the fully participating practices versus the non-participating practices estimated from the conditional Poisson model.

  • ‡For definition of ambulatory care sensitive conditions, please refer to e-table 1.

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

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