Methodological Issues in Measuring Restrictive Care Practices (Mechanical/physical restraint, Chemical restraint and Seclusion) in Adult Mental Health Inpatient Units: A Systematic Review of Recent Literature

AimsTo identify and characterise the approaches and instruments used in recent literature to measure the prevalence of restrictive care practices in adult mental health inpatient units. Additionally, it sought to summarise the reported psychometric properties, including reliability and validity of these measures.MethodsA systematic review of recent litratures was conducted using Scopus, MEDLINE, CINAHL, PsycINFO, Web of Science and Embase databases to identify studies published from 1 January 2010 to 11 October 2023. A total of 128 studies measuring the use of restrictive care practices were included. Data on measurement methods were extracted from each study and summarised to compare how consistently these practices have been measured across studies and how authors consistently reported the reliability and validity of these measurment approaches. All findings were reported following the PRISMA 2020 checklist.ResultsThere were significant variations in how the prevalence of restrictive care practices was measured, and the reliability and validity of these measurements were unclear for most studies. Only 11 studies reported inter/intra-rater reliability. Key variations were observed in data sources utilised, how and by whom the data were collected, the timing and total duration of data collection during patient admission, how and by whom data were extracted from secondary sources, measurement instruments and the reported reliability and validity of measures.ConclusionsMethodological inconsistencies about the measurements approaches of restricitve care practices would introduduce potential random and/or systematic biases on the reported data which may obscure the the true prevalance these practices. This hinder the ability to acurately assess the effectiveness of reduction strategies and understand the naturally occuring practices. Establishing a standardised set of reliable measures is crucial for enabling valid comparisons for the rates of restricitve car epractice use across settings and countries, which could enhance the ongoing monitoring and reduction of these practices.Relevance to the Clinical PracticeThe absence of standardised defintions and measurement approaches for restrictive care practices challenges the global effort to reduce their use. Without reliable and common measures, clinicians and researchers often face challenges in documening RCP incidents accurately, compromising efforts to improve care quality and support a recovery-oriented approach. Such measurment errors would mislead decission-maker which would furhter contribute to the inconsistency the the implementation of these practices.Patient or Public ContributionNo patient or public contribution.Trial RegistrationPROSPERO: CRD:42022335167;
