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.
