Influence of Education and Income on Receipt of Dementia Care in Sweden.

Abstract Objective To explore the dementia diagnostic process and drug prescription for persons with dementia (PWD) with different socioeconomic status (SES). Design Register-based cohort study. Setting and Participants This study included 74,414 PWD aged ≥65 years from the Swedish Dementia Register (2007–2018). Their data were linked with the Swedish Longitudinal Integrated Database for Health Insurance and Labor Market Studies (2006–2017) to acquire the SES information 1 year before dementia diagnosis. Methods Education and income—2 traditional SES indicators—were divided into 5 levels. Outcomes comprised the dementia diagnostic examinations, types of dementia diagnosis, diagnostic unit, and prescription of antidementia drugs. Binary logistic regression was performed to evaluate socioeconomic inequalities. Results Compared to PWD with the lowest educational level, PWD with the highest educational level had a higher probability of receiving the basic diagnostic workup [odds ratio (OR) 1.19, 95% confidence interval (CI) 1.10-1.29], clock test (OR 1.12, 95% CI 1.02-1.24) and neuroimaging (OR 1.23, 95% CI 1.09-1.39). Compared with PWD in the lowest income quintile, PWD in the highest income quintile presented a higher chance of receiving the basic diagnostic workup (OR 1.35, 95% CI 1.26-1.46), clock test (OR 1.40, 95% CI 1.28-1.52), blood analysis (OR 1.21, 95% CI 1.06-1.39), Mini-Mental State Examination (OR 1.47, 95% CI 1.26-1.70), and neuroimaging (OR 1.30, 95% CI 1.18-1.44). PWD with higher education or income had a higher likelihood of obtaining a specified dementia diagnosis or being diagnosed at a memory clinic. SES presented no association with prescription of antidementia medication, except for the association between education and the use of memantine. Conclusions and Implications Higher education or income was significantly associated with higher chance of receiving dementia diagnostic examinations, a specified dementia diagnosis, being diagnosed at a memory clinic, and using memantine. Socioeconomic inequalities in dementia diagnostic process and prescription of memantine occurred among PWD with different education or income levels.
