Background: This study examined the long-term preventive effects of a case management service on suicide reattempts, and clarified the factors related to suicide reattempts.
Methods: We 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.
Results: We 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).
Conclusion: Case 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.
