An Emergency Department-Initiated Intervention to Lower Relapse Risk after Attempted Suicide.
Suicide & Life-threatening Behavior 2019 Februrary 15
OBJECTIVE: According to randomized trials, contact after a suicide attempt lowers relapse risk. However, effectiveness studies based on real clinical data can provide additional external validity.
METHOD: We conducted an observational study to determine if an emergency department (ED)-initiated intervention for suicide attempt risk reduction, consisting on scheduling a single added appointment within 7 days after discharge following a suicide attempt, can reduce the risk of relapse. The study included 1,775 patients who had been treated at a general hospital ED due to a suicide attempt. The principal outcome measure was ED return after a new attempt. We obtained Kaplan-Meier survival functions and used Cox proportional hazard regression models to estimate unadjusted and adjusted risks of relapse by treatment phase. Covariates included: age, gender, history of suicide attempts, history of psychiatric disorders, concurrent alcohol/drug abuse, number of attempts during follow-up, admission as an inpatient and family support.
RESULTS: A total of 497 (22.5%) attempts were followed by a relapse. Subjects exposed to the studied intervention had a lower risk of relapse after a suicide attempt, with a 24% adjusted risk reduction estimate.
CONCLUSION: Our real-world results suggest that an additional early appointment, scheduled before discharging suicide attempters, reduces suicide reattempt risk.
