BACKGROUND Relapse prevention is an important objective in the management of serious mental illness (SMI). While community mental health nurses (CMHN) might be well-placed to support people with SMI in averting relapse, no systematic reviews have examined this association. AIM To review the evidence from studies reporting an association between CMHN exposure and hospitalisation of persons living with SMI (a proxy for relapse). METHODS Searches were undertaken in ten bibliographic databases and two clinical trial registries. We included studies of patients with SMI, where CMHN was the exposure, and the outcome was relapse (i.e. readmission to a psychiatric inpatient facility). Quality assessment of included studies was completed using two risk-of-bias measures. RESULTS Two studies met the inclusion criteria. Studies were rated as being of low-moderate methodological quality. There was insufficient evidence to conclude that community mental health nursing reduced the risk of admission to psychiatric inpatient facilities. CONCLUSIONS The review found no evidence that CMHN was associated with higher or lower odds of admission to psychiatric inpatient facilities among patients with SMI. The findings of the review point to a need for further research to investigate the impact of CMHN exposure and relapse in people with SMI. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42017058694.

社区精神卫生护理与重度精神疾病患者住院之间的关联：系统评价。

背景技术预防复发是严重精神疾病（SMI）管理中的重要目标。虽然社区心理健康护士（CMHN）可以很好地支持SMI患者避免复发，但尚无系统的评论来检查这种关联。目的回顾研究报告的证据，这些研究报告了CMHN暴露与SMI患者（复发的代表）的住院之间的关联。方法在十个书目数据库和两个临床试验注册中心进行检索。我们纳入了对SMI患者的研究，其中CMHN是暴露的，其结果是复发（即再次入住精神病院）。纳入研究的质量评估使用两种偏倚风险衡量方法完成。结果两项研究符合纳入标准。研究被认为是低中等的方法论质量。没有足够的证据可以得出结论，社区精神卫生护理减少了进入精神科住院设施的风险。结论该评论没有发现CMHN与SMI患者入院精神病院的几率较高或较低有关。审查的结果表明，需要进一步研究以调查CMHN暴露和SMI患者复发的影响。系统审查注册PROSPERO CRD42017058694。结论该评论没有发现CMHN与SMI患者入院精神病院的几率较高或较低有关。审查的结果表明需要进一步研究以调查CMHN暴露和SMI患者复发的影响。系统审查注册PROSPERO CRD42017058694。结论该评论没有发现CMHN与SMI患者入院精神病院的几率较高或较低有关。审查的结果表明需要进一步研究以调查CMHN暴露和SMI患者复发的影响。系统审查注册PROSPERO CRD42017058694。
