Telephone-Delivered Interventions for Suicide Prevention in Schizophrenia and Related Disorders: A Systematic Review

Abstract

Introduction Suicide is a health concern among individuals diagnosed with schizophrenia. Telehealth technology has become an emerging intervention that may afford opportunities for reaching this at-risk group. Consideration of the implementation of telehealth systems in the treatment of patients diagnosed with schizophrenia and suicidal behavior calls for a review of the evidence. Objectives The present aim was to explore the literature on the effectiveness of suicide prevention telephone delivered interventions among patients with schizophrenia and related disorders. Methods The bibliographic search was performed in the electronic databases PubMed, PsycInfo, Scopus, and Web of Science following PRISMA guidelines. Two reviewers independently conduct screenings, data extraction and methodological quality assessment. A total of 352 articles were retrieved, of which five studies met the eligibility criteria. Results Based on the limited data available, the use of modalities involving telephone contacts appears to be feasible in patients with schizophrenia and suicidal behaviors. In addition, preliminary evidence suggests this system appears to reduce suicidal ideation. Conclusions The current data presented here reflect an early stage of effectiveness of telephone-delivered interventions targeted at suicide prevention in patients with schizophrenia. Further research is needed to design evidence-based future interventions and to determine whether this approach can improve patient outcomes.
