The relationship between area deprivation and contact with community intellectual disability psychiatry

BackgroundPeople with intellectual disabilities (ID) have high rates of psychiatric illness and are known to live in more deprived areas than the general population. This study investigated the relationship between area deprivation and contact with ID psychiatry. MethodPsychiatric case notes and electronic records were used to identify all patients who had face-to-face contact with community ID psychiatric services over 1 year in the North East Community Health Partnership of Greater Glasgow and Clyde (estimated population 177867). The Scottish Index of Multiple Deprivation (SIMD) were determined for the patient sample and for the general population living in the same area. ResultsBetween 1 June 2012 and 1 June 2013, 184 patients were seen by ID psychiatry over a total of 553 contacts, with valid SIMD data for 179 patients and 543 contacts. Fifty-two per cent of patients (n=93) lived in the most deprived SIMD decile, and 90.5% (n=152) in the lowest 5 deciles. Compared with the general population, there were significantly more patients than expected living in the most deprived decile (Fisher's Exact test, P=0.009) and in the most deprived 5 deciles (Fisher's Exact test, P=0.001). The median number of contacts was 2 (interquartile range=1-3). There was no significant association between the number of contacts and SIMD decile. Forty-eight point one per cent (n=261) of all contacts were with patients living in the most deprived decile and 88.6% (n=481) in the most deprived 5 deciles. This was significantly more than expected compared with general population data (Fisher's Exact test, P=0.008 and Fisher's Exact test, P0.001). ConclusionsIn the area under study, contact with ID psychiatry was greater in more deprived areas. Given the high psychiatric morbidity of people with ID, if services do not adjust for deprivation, this may lead to further discrimination in an already disadvantaged population.
