Five year dementia registry in Thailand: Regional distribution, etiologies, and outcome of dementia

Abstract Background There is a lack of epidemiological knowledge about whether individuals with dementia receive the same quality of diagnostics and treatment. Method We explored the ICD10 National Health Security Office (NHSO) in‐patient record of dementia in Thailand. We analyzed the prevalence, etiologies, regional distribution, and outcome of dementia in Thailand during 2015‐2019. We reviewed a cross‐sectional cohort study based on data from the NHSO. Result Studied in‐patients diagnosed with dementia between 2015 and 2019 (n = 29,895; 40,981 visits) 17,058(57.1%) were female. 3,665(12.3%); 11,638(38.9%); 8,845(29.6%); 1,814(6.1%); 1,418(4.7%); and 2,515(8.4%) were in the northern, central, northeast, eastern, western, and southern part of Thailand respectively. Among 29,895 dementia cases, 15.4%, 18.7%, 20.2%, 24.1%, and 21.6% were prevalence cases in 2015, 2016, 2017, 2018, and 2019 (registered up to 30 th September where was the end of fiscal year) respectively. 16.1% were single, 68.5% were married, 6.6% were divorced, and 8.9% had other marital status. 85% aged 65 and over. Mean age of these cohort was 75.42(sd = 11.97) years old. The etiologies registered as dementia were as followed: 9.3% had AD, 0.2% had bvFTD, 9.3% ha VaD, 2.1% had other degenerative dementia, 77.4% ha unspecified dementia, and 1.8% had cognitive impairment due to metabolic and physiological condition. During these 5 years, 59.3% were dead. Mean duration of admission were 9.84(sd = 19.84) days. Mean cost of expense during admission were 31,521.79(sd = 80,647.68) Baht. Conclusion The dementia registry offers the surrogate clinical best practice and patient outcomes. The importance and significance in having dementia data cannot be undervalued.
