| Pre-health check | Post-health check | Change in IRR (95% CI) vs age-sex-practice matched controls† | |||||
|---|---|---|---|---|---|---|---|
| Outcome | Total admissions | Annual rate/1000 | Total admissions | Annual rate/1000 | Period IRR* (95% CI) | ||
| Patients with ID with health check (n=7487) | All emergency admissions | 1673 | 145.7 | 3840 | 173.2 | 1.22 (1.11 to 1.34) | 0.96 (0.87 to 1.07) |
| Emergency ACSCs only‡ | 602 | 52.4 | 1314 | 59.3 | 1.11 (0.95 to 1.29) | 0.82 (0.69 to 0.99) | |
| All elective admissions§ | 1328 | 115.9 | 2703 | 122.4 | 1.11 (1.01 to 1.21) | 0.96 (0.87 to 1.06) | |
| Patients with ID without health check but assigned a random index date (n=6922) | All emergency admissions | 1836 | 186.0 | 4263 | 212.2 | 1.20 (1.09 to 1.32) | 1.05 (0.94 to 1.17) |

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.

§Excludes patients with abnormally high elective rates (average >6/year).
ACSC, ambulatory care sensitive condition; ID, intellectual disability; IRR, incident rate ratio.
