Estimated prevalence of people with learning disabilities: template for general practice

BACKGROUND In 2001, a white paper set out a commitment to ensure that people with a learning disability receive equal access to health services, with an expectation that general practices would have identified all people with a learning disability registered with the practice by June 2004.

AIM To outline the development of a template to create practice-based registers of people with learning disabilities in general practice.

DESIGN OF STUDY The study was prospective, employing a template to identify patients in general practice with a learning disability. The study used capture-recapture methodology to estimate the prevalence of learning disability in the population.

SETTING General practices in Leeds.

METHOD A template was developed that uses Read code searches of practices' electronic medical records, along with practice knowledge to identify patients who have a learning disability.

RESULTS The tool was piloted in 30 general practices in Leeds and validated against a city-wide database of people with learning disability. There was a wide variation between the practices in terms of how many people were identified, with the average being 0.4% of the practice population. Combined with validation from the city-wide database, this increased to 0.7%.

CONCLUSION The template provides a valuable tool for general practices to begin developing a practice-based register of patients with a learning disability. This is particularly timely in view of the revised General Medical Services contract Quality and Outcomes Framework indicator, stimulating practices to produce a register of patients with learning disability. Use of a common definition for learning disability is needed to improve consistency in identification across practices
