BackgroundThis study examined the long-term preventive effects of a case management service on suicide reattempts, and clarified the factors related to suicide reattempts.MethodsWe reviewed the medical records of suicide attempters who visited the emergency department of Ulsan University Hospital from August 28, 2013 to July 31, 2017. A 4-week case management service was provided to consenting participants, either face-to-face or by telephone. Using survival analysis, we analyzed differences in the time to the next emergency department visit for a suicide attempt according to whether participants completed the case management service. We also assessed which characteristics of participants were associated with suicide reattempts.ResultsWe found no overall difference in time to suicide reattempt between case-managed participants and controls over the entire observation period (median period: 19 months). However, in the first 24 weeks after the initial suicide attempt, the case-managed group showed a longer time to reattempt than did the control group (log-rank test = 4.243; P = 0.039). A higher risk of reattempt was found among participants with the medical benefit type of health insurance compared to those with national health insurance (hazard ratio [HR], 5.134; P < 0.001) and among participants aged 20-39 compared to those aged ≥ 60 (HR, 3.502; P = 0.05).ConclusionCase management had only short-term benefits (within 24 weeks of initial suicide attempt). Risk factors for suicide reattempts were having a medical benefit health insurance and being aged 20-39 years.
