A multicomponent family support intervention in intensive care units: study protocol for a multicenter cluster-randomized trial (FICUS Trial)

Multicomponent family support intervention in intensive care units: statistical analysis plan for the cluster-randomized controlled FICUS trial

The FICUS trial is a cluster-randomized superiority trial to determine the effectiveness of a nurse-led, interprofessional family support intervention (FSI) on the quality of care, family management and individual mental health of family members of critically ill patients, compared to usual care. This paper describes the statistical analysis plan of the FICUS trial. The primary outcome is quality of family care, assessed by the Family Satisfaction in ICU Questionnaire (FS-ICU-24R) at patient discharge from the ICU. Several secondary outcomes are additionally assessed 3, 6, and 12 months thereafter. Sixteen clusters (ICUs) were randomly assigned 1:1 to FSI or usual care using minimization (8 per treatment). The target sample size is 56 patients per cluster (896 in total). Recruitment has been completed in January 2024. The follow-up of the last participant will be completed in early 2025. The primary and secondary outcomes will be analyzed by linear mixed-effects models (LMM). The main model for the primary outcome will include a random intercept per cluster with treatment (FSI vs. usual care) as the only explanatory variable due to the relatively small number of clusters. In addition, covariate-adjusted analyses will be conducted, including two cluster-level characteristics used in the minimization as well as participant-level characteristics. Moreover, a number of subgroup analyses by cluster- and participant-level characteristics are pre-specified.Trial registration ClinicalTrials.gov NCT05280691 . Registered on February 20, 2022.

Tailored implementation of the FICUS multicomponent family support intervention in adult intensive care units: findings from a mixed methods contextual analysis

BACKGROUND

The Family in Intensive Care UnitS (FICUS) trial investigates the clinical effectiveness of a multicomponent, nurse-led interprofessional family support intervention (FSI) and explores its implementation in intensive care units (ICUs). The local context of each ICU strongly influences intervention performance in practice. To promote FSI uptake and to reduce variation in intervention delivery, we aimed to develop tailored implementation strategies.

METHODS

A mixed method contextual analysis guided by the Consolidated Framework for Implementation Research (CFIR) was performed from March to June 2022 on eight ICUs assigned to the intervention group. ICU key clinical partners were asked to complete a questionnaire on CFIR inner setting measures (i.e., organizational culture, resources, learning climate and leadership engagement) and the Organizational Readiness for Implementing Change (ORIC) scale prior to group interviews, which were held to discuss barriers and facilitators to FSI implementation. Descriptive analysis and pragmatic rapid thematic analysis were used. Then, tailored implementation strategies were developed for each ICU.

RESULTS

In total, 33 key clinical partners returned the questionnaire and 40 attended eight group interviews. Results showed a supportive environment, with CFIR inner setting and ORIC measures each rated above 3 (scale: 1 low-5 high value), with leadership engagement scoring highest (median 4.00, IQR 0.38). Interview data showed that the ICU teams were highly motivated and committed to implementing the FSI. They reported limited resources, new interprofessional information exchange, and role adoption of nurses as challenging.

CONCLUSION

We found that important pre-conditions for FSI implementation, such as leadership support, a supportive team culture, and a good learning climate were present. Some aspects, such as available resources, interprofessional collaboration and family nurses' role adoption were of concern and needed attention. An initial set of implementation strategies were relevant to all ICUs, but some additions and adaptation to local needs were required. Multi-component interventions are challenging to implement within complex systems, such as ICUs. This pragmatic, theory-guided, mixed methods contextual analysis demonstrated high readiness and commitment to FSI implementation in the context of a clinical trial and enabled the specification of a tailored, multifaceted implementation strategy.

Supporting families of patients who die in adult intensive care: A scoping review of interventions

BACKGROUND

Families who perceive themselves as prepared for an impending death experience reduced psychological burden during bereavement. Understanding which interventions promote death preparedness in families during end-of-life care in intensive care will inform future intervention development and may help limit the burden of psychological symptoms associated with bereavement.

AIM

To identify and characterise interventions that help prepare families for the possibility of death in intensive care, incorporating barriers to intervention implementation, outcome variables and instruments used.

DESIGN

Scoping review using Joanna Briggs methodology, prospectively registered and reported using relevant guidelines.

DATA SOURCES

A systematic search of six databases from 2007 to 2023 for randomised controlled trials evaluating interventions that prepared families of intensive care patients for the possibility of death. Citations were screened against the inclusion criteria and extracted by two reviewers independently.

RESULTS

Seven trials met eligibility criteria. Interventions were classified: decision support, psychoeducation, information provision. Psychoeducation involving physician-led family conference, emotional support and written information reduced symptoms of anxiety, depression, prolonged grief, and post-traumatic stress in families during bereavement. Anxiety, depression, and post-traumatic stress were assessed most frequently. Barriers and facilitators to intervention implementation were seldom reported.

CONCLUSION

This review provides a conceptual framework of interventions to prepare families for death in intensive care, while highlighting a gap in rigorously conducted empirical research in this area. Future research should focus on theoretically informed, family-clinician communication, and explore the benefits of integrating existing multidisciplinary palliative care guidelines to deliver family conference within intensive care.

IMPLICATIONS FOR CLINICAL PRACTICE

Intensive care clinicians should consider innovative communication strategies to build family-clinician connectedness in remote pandemic conditions. To prepare families for an impending death, mnemonic guided physician-led family conference and printed information could be implemented to prepare families for death, dying and bereavement. Mnemonic guided emotional support during dying and family conference after death may also assist families seeking closure.

Implementation of a multicomponent family support intervention in adult intensive care units: study protocol for an embedded mixed-methods multiple case study (FICUS implementation study)

BACKGROUND

The implementation of complex interventions is considered challenging, particularly in multi-site clinical trials and dynamic clinical settings. This study protocol is part of the family intensive care units (FICUS) hybrid effectiveness-implementation study. It aims to understand the integration of a multicomponent family support intervention in the real-world context of adult intensive care units (ICUs). Specifically, the study will assess implementation processes and outcomes of the study intervention, including fidelity, and will enable explanation of the clinical effectiveness outcomes of the trial.

METHODS AND ANALYSIS

This mixed-methods multiple case study is guided by two implementation theories, the Normalisation Process Theory and the Consolidated Framework for Implementation Research. Participants are key clinical partners and healthcare professionals of eight ICUs allocated to the intervention group of the FICUS trial in the German-speaking part of Switzerland. Data will be collected at four timepoints over the 18-month active implementation and delivery phase using qualitative (small group interviews, observation, focus group interviews) and quantitative data collection methods (surveys, logs). Descriptive statistics and parametric and non-parametric tests will be used according to data distribution to analyse within and between cluster differences, similarities and factors associated with fidelity and the level of integration over time. Qualitative data will be analysed using a pragmatic rapid analysis approach and content analysis.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Cantonal Ethics Committee of Zurich BASEC ID 2021-02300 (8 February 2022). Study findings will provide insights into implementation and its contribution to intervention outcomes, enabling understanding of the usefulness of applied implementation strategies and highlighting main barriers that need to be addressed for scaling the intervention to other healthcare contexts. Findings will be disseminated in peer-reviewed journals and conferences.

Psychometric Properties of the Portuguese Version of the Iceland-Family Perceived Support Questionnaire in Parents of Children and Adolescents with Chronic Condition

The support from nurses perceived by family members of children with chronic conditions has been shown to be a protective factor at different levels in a family's health. As such, nurses need to have instruments that assess this perception to increase the quality of the care provided to those families. This methodological study aimed to analyze the psychometric properties of the Portuguese translation of the Iceland-Family Perceived Support Questionnaire (ICE-FPSQ) in parents of children/adolescents with chronic conditions. The ICE-FPSQ was administered to 237 parents recruited from the day hospital and outpatient services of four hospitals in Northern Portugal. Cronbach's alpha reliability coefficients for the Total Scale, Cognitive Support, and Emotional Support subscales were excellent (α = 0.96, α = 0.93, α = 0.96, respectively). Reasonable fit indexes were found by confirmatory factor analysis (χ²/df = 2.799; CFI = 0.960; PCFI = 0.791, and RMSEA = 0.087), indicating a good model fit to the original structure. The ICE-FPSQ is a valid and reliable instrument to measure perceived support.
