Abstract
INTRODUCTION: There is a lack of distinct and measurable outcomes in psychiatric and/or mental health nursing which negatively impacts guiding clinical practice, assessing evidence-based nursing interventions, ensuring future-proof nursing education and establishing visibility as a profession and discipline. Psychiatric and/or mental health nursing struggle to demonstrate patient-reported outcomes to assess the effectiveness of their practice. A systematic review that summarising patient-reported outcomes, associated factors, measured nursing care/interventions and used measurement scales of psychiatric and/or mental health nursing in the adult population in acute, intensive and forensic psychiatric wards in hospitals will capture important information on how care can be improved by better understanding what matters and what is important to patients themselves. This review can contribute to the design, planning, delivery and assessment of the quality of current and future nursing care METHODS AND ANALYSIS: This protocol follows the Cochrane methodological guidance on systematic reviews of interventions and The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol. The search strategy will be identified by consultations with clinical and methodological experts and by exploring the literature. The databases Ovid MEDLINE, CINAHL, EMBASE, APA PsychARTICLES, Web of Science and Scopus will be searched for all published studies. Studies will be screened and selected with criteria described in the population, intervention, control and outcomes format after a pilot test by two researchers. Studies will be screened in two stages: (1) title and abstract screening and (2) full-text screening. Data extraction and the quality assessment based on the Johanna Briggs Institute guidelines will be conducted by two researchers. Data will be presented in a narrative synthesis. ETHICS AND DISSEMINATION: No ethical approval is needed since all data are already publicly accessible. The results of this work will be published in a peer-reviewed scientific journal.
