title: Depression and suicidal behaviors in Medicare primary care patients under age 65.
abstract: OBJECTIVE
  To examine suicidal behavior and depression prevalence among a group of Medicare patients under age 65 with functional impairment and recent significant health care services use.
  
  
  METHODS
  An observational study of baseline characteristics of participants in a randomized controlled trial.
  
  
  METHODS
  A Medicare demonstration (N=1,605) that enrolled primary care patients in 8 counties in New York, 6 counties in West Virginia, and 5 counties in Ohio.
  
  
  METHODS
  All demonstration participants under age 65 (n=164). Participants were required to have impairment in at least 2 activities of daily living or 3 instrumental activities of daily living, and to have had recent significant health care use.
  
  
  METHODS
  None.
  
  
  RESULTS
  The Paykel questionnaire for suicidal ideation and attempts, the Mini-international Neuropsychiatric Interview Major Depressive Episode module, and the 15-item Geriatric Depression Scale were administered at baseline; 14.8% of the patients indicated suicidal ideation during the past year, 4.9% reported a suicide attempt during that time, 25.9% indicated at least 1 lifetime suicide attempt, 34.6% had a major depressive episode in the last month, and 58.3% had clinically significant depressive symptoms during the previous week.
  
  
  CONCLUSIONS
  These levels of suicidal ideation and behaviors and of depression are far higher than those found in studies of nonelderly American adults, and may indicate the need for routine screening in this population.
