Immigrant Patients with Dementia and Memory Impairment in Primary Health Care in Norway: A National Registry Study

摘要

Background: Immigrants comprise a growing proportion of the elderly population. However, knowledge about the diagnosis and management of dementia and memory impairment among immigrants is scarce in Norway and elsewhere. Aims: To compare proportions of Norwegians and immigrants aged >= 50 years with a diagnosis of dementia or memory impairment in primary health care and to study the demographic characteristics, utilization of primary health care services and pharmacological treatment of Norwegians and immigrants with either of the two diagnoses in 2008. Method: This is a registry-based study using linked data at the individual level from 4 national Norwegian registers. Results: A significantly lower proportion of immigrants, especially those from other than high-income countries, had a diagnosis of dementia or memory impairment. Among patients with such diagnoses, anti-dementia medication was purchased 20-50% more often by Norwegians than by immigrants, although the differences remained significant only for immigrants from other than high-income countries after adjustment for several variables. Conclusion: The lower proportions of immigrants with a dementia diagnosis and lower proportions of patients receiving treatment might indicate a lower prevalence or milder forms of dementia among immigrants. However, the cultural validity of the assessment tools, linguistic barriers and challenges for general practitioners should be further investigated. (C) 2015 S. Karger AG, Basel
