Abstract

Background: Data on the rate of dementia is essential for planning and developing appropriate services at the national level. Objective: We report the prevalence and incidence of dementia, based on electronic health records available for the whole population. Methods: This national dementia dataset was established as a part of the National Program to Address Alzheimer's and Other Types of Dementia. Data from medical health records for all persons aged 45+ in Israel, for 2016, were extracted from the databases of the four health maintenance organizations. Dementia cases were identified based on either recorded dementia diagnosis, through International Classification of Diseases (ICD-9 and ICD-10) or dispensation of anti-dementia drugs. The date of first diagnosis was determined by the earliest recording. Results: A total of 65,951 persons with dementia, aged 45+, were identified from electronic health data. Based on both ICD codes and anti-dementia drugs, the prevalence rates of dementia among individuals aged 45+ and 65+ in 2016 were 2.5%and 6.4%, respectively, and the incidence rates were 0.49%and 1.3%, respectively. Based on ICD codes alone, the prevalence rates of dementia among individuals aged 45+ and 65+ in 2016 were 2.1%and 5.4%respectively, and the incidence rates were 0.36%and 0.96%respectively. The rates were higher among females compared to males and paradoxically lower in lower socioeconomic status compared to higher statuses. Conclusion: This data collection reflects the present access of dementia patients to medical care resources and provides the basis for service planning and future dementia policies.
