  • *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.

  • †Has been classed as having severe or profound ID by the GP or has two or more of the following in addition to an ID diagnosis: epilepsy, cerebral palsy or significant mobility problem (wheelchair use or greater problem), severe visual impairment, severe hearing impairment, a continence problem, or use of PEG feeding.

  • ID, intellectual disability; IRR, incidence rate ratio; GP, general practitioner; PEG, percutaneous endoscopic gastrostomy.
