title: Epidemiology of mental and behavioral disorders among the elderly: based on data of hospitalized patients in Thailand 2010.
abstract: BACKGROUND
  To date, only small, selected groups of elderly hospitalized with mental and behavioral disorders (EHMBD) have been studied. Since no national epidemiological studies have been published, the recent advent of universal healthcare in Thailand makes doing such a study timely for improving the medical curricula and service provision.
  
  
  OBJECTIVE
  To analyze the epidemiology of the EHMBD in the year 2010 of Thailand.
  
  
  METHODS
  The data analyzed were gathered from Medical Expense Reimbursement forms submitted for the fiscal year 2010. The particular focus of this research was on elderly inpatient aged 60 years and over with ICD-10 (for 2010) diagnosis: F00-F99 Mental and Behavioral Disorders. The authors extracted and analyzed the number of in-patient department (IPD) admissions, psychiatric diagnoses, length of hospital stays, hospital charges and mortality rate. Data were analyzed using SPSS 17 for Windows.
  
  
  RESULTS
  In 2010, EHMBD accounted for 11,418 admissions which was 1.56 admission per 1000 elderly people or 13.9% of overall admission (19 years and over). Of the 11,418 admission, 44 died (0.39%). The mean in-patient charges/admission in Thai Baht (SD) for the EHMBD with any F00-F99 diagnosis was 12,896 (51,659). The average range of stay was 8.3 +/- 22.2 days. The leading diagnosed clusters of behavioral and mental disorders were organic mental disorders (F00-F09: 23.8%), neurotic, stress-related and somatoform disorders (F40-F48: 21.1%); and mental and behavioral disorders due to use of alcohol (F10: 20.3%). Alcohol use disorders among the elderly resulted in four times more men being hospitalized than women. Regarding the F30-F39 cluster mood (affective) disorders, the prevalence of depressive episodes increased with age and bipolar affective disorder decreased with age.
  
  
  CONCLUSIONS
  The prevalence of hospitalization among the elderly with mental and behavioral disorders was about one-eighth that of all admission of adult from 19 years old. Death was an uncommon result. The most common psychiatric diagnoses were organic mental disorders, neurotic, stress-related and somatoform disorders and mental and behavioral disorders due to use of alcohol.
