title: Suicide after hospitalization in the elderly: a population based study of suicides in Northern Finland between 1988-2003.
abstract: OBJECTIVE
  Elderly people commit suicide more often than people under the age of 65. An elevated risk is also attached to depression and other axis I psychiatric disorders. However, little is known about the preferred suicide method, effect of primary psychiatric diagnosis, and length of time between discharge from psychiatric hospitalization and suicide. The lack of information is most apparent in the oldest old (individuals over 75 years).
  
  
  METHODS
  On the basis of forensic examinations, data on suicide rates were separately examined for the 50-64, 65-74 and over 75 year-olds (Total n=564) with regard to suicide method, history of psychiatric hospitalization and primary diagnoses gathered from the Finnish Hospital Discharge Register. Study population consisted of all suicides committed between 1988 and 2003 in the province of Oulu in Northern Finland.
  
  
  RESULTS
  Of the oldest old, females had more frequent hospitalizations than males in connection with psychiatric disorders (61% vs 23%), of which depression was the most common (39% vs 14%). In this age group, 42% committed suicide within 3 months after being discharged from hospital and 83% used a violent method. Both elderly males and females were less often under the influence of alcohol, but used more often violent methods than middle-aged persons.
  
  
  CONCLUSIONS
  Suicide rates within the first 3 months following discharge from hospital in the 65-74 and the over 75 year olds were substantial and should influence post-hospitalization treatment strategies. To reduce the risk of suicides in elderly patients discharged from hospital, close post-hospitalization supervision combined with proper psychoactive medication and psychotherapy, are possible interventions.
