Summary

The post-discharge suicide risk among psychiatric patients is significantly higher than it among patients with other diseases and general population. The brief contact interventions (BCIs) are recommended to decrease the risk in areas with limited mental health service resource like China, however the best frequency to implement BCIs is unknown. This implementation study aims to 1) to develop an intervention strategy against post-discharge suicide based on BCIs for Chinese psychiatric patients; 2) to determine the best frequency of BCIs based on Sequential Multiple Assignment Randomized Trial; 3) to evaluate the effectiveness of the intervention strategy and explore its implementability based on the Implementation Outcome Framework (IOF). Based on the community-based participatory research (CBPR) approach, this study will invite psychiatric patients and family members, psychiatrist and nurses, community mental health workers and social workers as the community team to develop a post-discharge suicide intervention strategy. The study will recruit patients with psychotic symptoms and with major depressive disorder discharged from Shenzhen Kangning Hospital (SKH) in a Sequential Multiple Assignment Randomized Trial (SMART) to determine the best frequency for implementing BCIs and to evaluate the effectiveness. Participants will be randomized into two intervention groups to receive BCIs at different frequencies. Follow-ups to evaluate participants' suicide risk are scheduled at 1, 3, 6 and 12 months after discharge. The re-randomization will be applied at 3 months after discharge. With the Intent-to-treat (ITT) approach, generalized estimating equation (GEE) and survival analysis (SA) will be applied to compare the effectiveness among groups and to explore factors associated with suicide risk. Meanwhile, this study will collect qualitative and quantitative information on implementation and service outcomes from the community team.

Brief contact intervention

The BCI in this study is a series of structured messages, and messages will be delivered to participants by pushing feeds through WeChat and an iOS/Android application developed for this study. If participants did not use smartphones, messages will be delivered by mobile text messages or by phone calls. Though the final details are yet to be determined by the CBPR study, the investigators expect to structure messages into six components including introduction, greetings for previous complains, mental health promotion, encouragement, and coping strategies, remind of treatment and subsequent visit, and crisis intervention resource. Noted, the same messages will also be sent to patients' LHSs.
