Meta-analysis of longitudinal cohort studies of suicide risk assessment among psychiatric patients: heterogeneity in results and lack of improvement over time

摘要: OBJECTIVE: It is widely assumed that the clinical care of psychiatric patients can be guided by estimates suicide risk and using patient characteristics to define a group high-risk patients. However, statistical strength reliability categorization unknown. Our objective was investigate odds in compared lower-risk categories rates groups. METHOD: We located longitudinal cohort studies where or people who had made attempts were stratified into groups for with mortality as outcome searching peer reviewed publications indexed PubMed PsychINFO. Electronic searches supplemented hand included relevant review articles. Two authors independently extracted data regarding effect size, study population design from 53 samples risk-assessed reported 37 studies. RESULTS: The pooled among calculated random effects meta-analysis 4.84 (95% Confidence Interval (CI) 3.79-6.20). Between-study heterogeneity very high (I2 = 93.3). There no evidence more recent greater than older Over an average follow up period 63 months proportion suicides 5.5% 0.9% meta-analytically derived sensitivity specificity 56% 79% respectively. publication bias favour inflated CONCLUSIONS: categorizations based on presence multiple factors does not greatly exceed association between individual suicide. A statistically strong reliable method usefully distinguish remains elusive. Language: en
