Statistical analysis of publicly funded cluster randomised controlled trials: a review of the National Institute for Health Research Journals Library

BACKGROUND

In cluster randomised controlled trials (cRCTs), groups of individuals (rather than individuals) are randomised to minimise the risk of contamination and/or efficiently use limited resources or solve logistic and administrative problems. A major concern in the primary analysis of cRCT is the use of appropriate statistical methods to account for correlation among outcomes from a particular group/cluster. This review aimed to investigate the statistical methods used in practice for analysing the primary outcomes in publicly funded cluster randomised controlled trials, adherence to the CONSORT (Consolidated Standards of Reporting Trials) reporting guidelines for cRCTs and the recruitment abilities of the cluster trials design.

METHODS

We manually searched the United Kingdom's National Institute for Health Research (NIHR) online Journals Library, from 1 January 1997 to 15 July 2021 chronologically for reports of cRCTs. Information on the statistical methods used in the primary analyses was extracted. One reviewer conducted the search and extraction while the two other independent reviewers supervised and validated 25% of the total trials reviewed.

RESULTS

A total of 1942 reports, published online in the NIHR Journals Library were screened for eligibility, 118 reports of cRCTs met the initial inclusion criteria, of these 79 reports containing the results of 86 trials with 100 primary outcomes analysed were finally included. Two primary outcomes were analysed at the cluster-level using a generalized linear model. At the individual-level, the generalized linear mixed model was the most used statistical method (80%, 80/100), followed by regression with robust standard errors (7%) then generalized estimating equations (6%). Ninety-five percent (95/100) of the primary outcomes in the trials were analysed with appropriate statistical methods that accounted for clustering while 5% were not. The mean observed intracluster correlation coefficient (ICC) was 0.06 (SD, 0.12; range, - 0.02 to 0.63), and the median value was 0.02 (IQR, 0.001-0.060), although 42% of the observed ICCs for the analysed primary outcomes were not reported.

CONCLUSIONS

In practice, most of the publicly funded cluster trials adjusted for clustering using appropriate statistical method(s), with most of the primary analyses done at the individual level using generalized linear mixed models. However, the inadequate analysis and poor reporting of cluster trials published in the UK is still happening in recent times, despite the availability of the CONSORT reporting guidelines for cluster trials published over a decade ago.

A Systematic Review of the Characteristics and Efficacy of Recovery Training for Mental Health Staff: Implications for Supported Accommodation Services

Evidence suggests a link between recovery-oriented practise and service user outcomes in supported accommodation settings. Current clinical guidelines recommend recovery training for supported accommodation staff, however evidence relating to the effectiveness of this type of training is unclear. This review aimed to describe and compare the characteristics and efficacy of existing recovery training packages for mental health staff. The appropriateness and applicability of the interventions was considered in relation to UK supported accommodation services. Initial search processes returned 830 papers. After duplicate removal, inclusion and exclusion criteria were applied to 489 papers, leaving a final sample of seven papers. Data were reviewed using a narrative synthesis approach. The reviewed papers showed variation in the aims, frequency, and duration of the training interventions, although all included content consistent with the five-domains of the CHIME model. All interventions used direct, in-person teaching, and prioritised interactive, experiential learning, however a number were limited by the absence of feedback, the use of one-off, rather than repeated/follow-up sessions, and a reliance on classroom-based, rather than in-vivo, training. There was limited evidence to suggest a consistent effect of training on staff or service user outcomes, and there was no clear association between the delivery and design characteristics of the interventions and reported outcomes. In considering the development of recovery training for supported accommodation staff, little guidance can be taken from the reviewed literature. Any training package must be developed with consideration of the unique contextual and organisational characteristics of these services. The authors recommend viewing training as one component of a broader goal of service transformation.

Factors associated with family functioning among people with a diagnosis of schizophrenia and primary family caregivers

WHAT IS KNOWN ON THE SUBJECT?: Families act not only as the primary support for people with a diagnosis of schizophrenia but also as partners in the healthcare system. Families who have members with mental disorders, particularly schizophrenia, experience challenges in family functioning. Research on families in relation to schizophrenia primarily focuses on the determinants that affect family functioning from primary family caregivers' perspectives. WHAT DOES THE PAPER ADD TO EXISTING KNOWLEDGE?: This report provides evidence that there is a concordance between family functioning and inpatient psychiatric rehabilitation facilities for the patient-caregiver dyad; both care-receivers and primary family caregivers considered family functioning as poor. Care-receivers with lower education levels, increased number of previous hospitalizations and poor quality of family-centred care experienced unhealthy family functioning. Primary family caregivers and care-receivers with higher education levels, lower suicidality and greater quality of family-centred care experienced healthier family functioning. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Understanding the degree of family functioning, particularly its concordance and correlates as perceived by patients and primary family caregivers, may serve as a platform for inculcating assessment of family functioning to achieve holistic patient care. Open dialogue in family-focused care planning is essential to facilitate collaborative partnerships and improve family functioning among people with a diagnosis of schizophrenia and their primary family caregivers. Further research on culturally relevant, evidence-based family interventions to enhance the functioning of affected families is warranted, especially for families with members in inpatient psychiatric rehabilitation facilities. ABSTRACT: Introduction Families provide frontline caregiving support for people with a diagnosis of schizophrenia. However, research primarily addresses correlates of family functioning from primary family caregivers' perspectives. Aim To examine perceived family functioning, particularly its concordance within patient-caregiver dyads and associated factors in families of people living with schizophrenia. Methods A cross-sectional, descriptive correlational design was used. A total of 133 dyads of patients and primary family caregivers from inpatient psychiatric rehabilitation services participated. Descriptive statistics, independent-sample t test, one-way ANOVA, Pearson's correlation coefficients, intraclass correlation coefficient and stepwise multiple linear regression analyses were applied. Results Family functioning was perceived as impaired by patient-caregiver dyads, and there existed a concordance in this regard. Patients' and family caregivers' education levels, patients' suicidality, number of previous hospitalizations and quality of family-centred care correlated with patients' and primary family caregivers' family functioning. Discussion Findings highlight the importance of patient- and family-reported family functioning with implications to address individual and collective concerns. Implications for Practice Evidence-based family interventions are crucial for assisting vulnerable families in promoting family functioning. Mental health nurses should facilitate collaboration and open dialogue concerning perspectives of patients and families to improve delivery of comprehensive mental health care.

A Systematic Review and Meta-analysis of Recovery Educational Interventions for Mental Health Professionals

The history of mental health care has been marked by various struggles in maintaining the dignity of service users. Some reform movements have started to use educational strategies aimed at the beliefs and attitudes of professionals, as well as changing the way that practice is carried out. This paper intends to systematically review and synthesize studies assessing awareness and training activities for mental health professionals covering aspects related to recovery, empowerment, and in general, rights-based care to achieve full citizenship of mental health services users. We reviewed 26 articles and were able to include 14 of them in meta-analytic calculations. Our results at the qualitative level show an evolution of the literature towards better quality designs and focus on aspects related to the impact and maintenance of the effects of these training activities. Meta-analytic calculations found high heterogeneity but no risk of biases and low-to moderate effect sizes with a statistically significant impact on beliefs and attitudes but not on practices. The importance of this information in improving and advancing these educational activities is addressed.

Co-production of "nature walks for wellbeing" public health intervention for people with severe mental illness: use of theory and practical know-how

Background

Interventions need to be developed in a timely and relatively low-cost manner in order to respond to, and quickly address, major public health concerns. We aimed to quickly develop an intervention to support people with severe mental ill-health, that is systematic, well founded both in theory and evidence, without the support of significant funding or resource. In this article we aim to open and elucidate the contents of the ‘black box’ of intervention development.

Methods

A multidisciplinary team of seven academics and health practitioners, together with service user input, developed an intervention in 2018 by scoping the literature, face-to-face meetings, email and telephone. Researcher fieldnotes were analysed to describe how the intervention was developed in four iterative steps.

Results

In step 1 and 2, scoping the literature showed that, a) people with severe mental illness have high mortality risk in part due to high levels of sedentary behaviour and low levels of exercise; b) barriers to being active include mood, stress, body weight, money, lack of programmes and facilities and stigma c) ‘nature walks’ has potential as an intervention to address the problem. In Step 3, the team agreed what needed to be included in the intervention so it addressed the “five ways to mental wellbeing” i.e., help people to connect, be active, take notice, keep learning and give. The intervention was mapped to key behavioural change concepts such as, personal relevance, relapse prevention, self-efficacy. In Step 4, the team worked out how best to implement the intervention. The intervention would be delivered over 12 weeks by members of the hospital team and community walk volunteers. Participants would receive a nature walks booklet and text messages.

Conclusions

We developed a theoretically-informed, evidence-based nature walks programme in a timely and relatively low-cost manner relevant in an era of growing mental illness and funding austerity. Further research is required to test if the intervention is effective and if this approach to intervention development works.
