Long-Term Impact of Community Psychiatric Care on Quality of Life amongst People Living with Schizophrenia: A Systematic Review

Abstract

The review examines the long-term impact of community psychiatric care on improving the quality of life of people with schizophrenia. It addresses the global burden of this disorder and the need for effective community-based care strategies. A systematic literature search was conducted in databases such as CINAHL, Medline, Web of Science, Sage and ScienceDirect, with the search lasting until March 2024 and following the PRISMA guidelines. The inclusion criteria targeted studies that addressed the long-term effects of community mental health care for people aged 18 years and older with schizophrenia and included both quantitative and qualitative research designs. Studies unrelated to the research question or with significant methodological flaws were excluded. The risk of bias was assessed using GRADE and GRADECERqual, in addition to critical appraisal using the Joanna Briggs Institute (JBI) checklists. Independent screening and data extraction was performed, with results summarised by thematic analysis. In total, 11 studies met the inclusion criteria and included cross-sectional, cohort, qualitative and randomised controlled trial designs. The results showed that community psychiatric care significantly improves the quality of life, well-being and social integration of people with schizophrenia. Effective interventions identified include psychoeducation, cognitive behavioural therapy, social skills training and individualised care plans. However, challenges such as limited resources, labour shortages and social stigma, particularly in low-income neighbourhoods, were also identified. This study highlights the importance of continuous, personalised, multidisciplinary community-based care for sustainable mental health outcomes. Further research is recommended to investigate the long-term impact and strategies to overcome implementation challenges.
