BACKGROUND: The elderly have the highest suicide rates in US. The elderly have the highest suicide rates in US. Old white males are at the greatest risk. Old white males are at the greatest risk. Late life suicide victims typically see their primary care physicians in the month prior to death. Late life suicide victims typically see their primary care physicians in the month prior to death. The majority of older suicide victims have had their first depressive episode in late life. The majority of older suicide victims have had their first depressive episode in late life. Although effective treatments exit, depression is often not detected or treated by the primary care physician. Although effective treatments exit, depression is often not detected or treated by the primary care physician.

Summary of PROSPECT Data on Sampling and Screening 4/1/02 81,185 patient appointments -- 16,704 sampled for CESD screening -- 16,704 sampled for CESD screening 54.2% were eligible and completed screening 54.2% were eligible and completed screening 27.6% refused screening 27.6% refused screening 7.5% were ineligible 7.5% were ineligible Of 9,136 CESD’s completed, 1,107(11.4%) screened positive. Patients who screened positive plus a 5% sample of screened negative patients were invited to participate in the study. In addition to the sampled patients, 68 patients who were not sampled were invited to participate in the study.

Summary of PROSPECT Data on Assessments 4/1/02 1,276 sampled and referred patients have completed baseline assessment. By using a high cut off score on the CESD(>20),PROSPECT was able to optimize its specificity(.925). 428(33.5%) met SCID/DSM-IV criteria for major depression 256(20.1%) had treatable minor depression

PROSPECT Enrollment Data Total enrollment: 1276 subjects, including 874 white and 347 black 889 women and 365 men Of 1313 patients who signed consent, 329(25.1%) terminated from all participation in the study(including 28 prior to completing the baseline interview). Mortality: 49 PROSPECT subjects have died, 1 by suicide (gun shot) and 48 by natural causes Psychiatric hospitalization: 11 Refusal of further participation: 133 Treatment discontinuation due to supervening medical problems or dementia: 332

PROSPECT Hypothesis Testing HYPOTHESIS: Compared to usual care, PROSPECT intervention is associated at four months follow-up with a greater reduction in depression, defined by 50% reduction in HDRS scores(“response”) and by absolute change in HDRS scores. TESTING: Mixed effect logistic regression and binary models for binary and continuous outcomes; Radon effects corresponded to the primary care practice

PROSPECT 4-Month Outcomes Overall, and at each site, the response rate was greater in intervention versus usual care practices(41.1% versus 27.4%) in unadjusted (p<.028) and adjusted (p<.024) analyses. Overall, and at each site, the response rate was greater in intervention versus usual care practices(41.1% versus 27.4%) in unadjusted (p<.028) and adjusted (p<.024) analyses. Factors that were also significantly associated with response included baseline diagnosis (MDD versus minor), gender, and study site. Factors that were also significantly associated with response included baseline diagnosis (MDD versus minor), gender, and study site. The PROSPECT intervention was associated with a significantly greater decrease in HDRS scores(-7.3 vs – 3.7) in both unadjusted (p<.001) and adjusted (p<.001) analyses.
