A SMART design to optimize treatment strategies for patient and family caregiver outcomes

Study protocol of a sequential, multiple assignment, randomised trial using an adaptive intervention to reduce loneliness among Chinese older adults in Hong Kong

BACKGROUND

Loneliness is a prevalent and alarming issue among older adults that requires effective interventions. While randomised controlled trials have been commonly undertaken to explore reduction in loneliness, there is a growing recognition that a comprehensive treatment strategy involving multiple interventions may yield better outcomes. Therefore, this study aims to develop and identify a two-stage adaptive intervention that combines telephone-delivered behavioural activation (Tele-BA) and mindfulness techniques (Tele-MF) to reduce loneliness in older adults in Hong Kong.

METHODS

A Sequential, Multiple Assignment, Randomised Trial (SMART) design will be adopted. 244 lonely older adults will be recruited from the community and randomly assigned to either one of the 4-week two-stage, embedded adaptive interventions involving different sequences and dosages of Tele-BA and Tele-MF (eg, 4 weeks of Tele-BA followed by booster sessions for responders or 4 weeks of Tele-BA followed by 4 weeks of Tele-BA with motivational component or 4 weeks of Tele-MF for non-responders) based on a set of decision rules. The primary outcome will be loneliness measured by the Revised University of California Los Angeles (UCLA) Loneliness Scale. Secondary outcomes, such as De Jong Gierveld Loneliness Scale, perceived stress, sleep quality and depressive and anxiety symptoms, will be assessed. Adhering to the intention-to-treat principles, the data will be analysed using linear mixed models. The findings may have implications for the development of psychosocial adaptive interventions involving BA and MF to reduce loneliness and improve well-being among older adults in Hong Kong using the SMART design.

ETHICS AND DISSEMINATION

Ethical approval was obtained by the Human Research Ethics Committee at The Education University of Hong Kong (reference: 2022-2023-0117). The findings from this study will be presented in academic conferences and submitted for publication.

Randomized Clinical Trial of a Self-care and Communication Intervention for Parents of Adolescent/Young Adults Undergoing High-Risk Cancer Treatment: A Report From the Children's Oncology Group

BACKGROUND

Parents of adolescents and young adults (AYAs) with cancer offer primary support to their children and often experience their own high levels of distress, affecting parent-AYA communication and quality of life.

OBJECTIVE

To reduce parent distress and improve communication during high-risk cancer treatment, we examined efficacy of a self-care and communication intervention for parents and indirect benefit for AYAs receiving a therapeutic music video (TMV) intervention.

METHODS

In this study, we conducted a multisite, randomized controlled trial with AYAs and parents enrolled as dyads (n = 110). Parents were randomized to intervention or low-dose control; all AYAs received TMV. Data collection occurred at baseline, 2 weeks post intervention (T2), and 90 days post intervention (T3).

RESULTS

There were no significant between-group differences on primary outcomes for parents or AYAs. We did find significant differences favoring the parent intervention group on parenting confidence at T2 and marginally better outcomes for family adaptability/cohesion at T3. Both groups exhibited significant within-group improvement for parent distress (state anxiety, T3; perceived stress, T2 and T3; mood, T3), state anxiety (T2) intervention only, and family strengths control group only. Qualitative data demonstrate the parent intervention raised self-awareness and parent confidence in the short term.

CONCLUSION

Parents found their intervention helpful. Absence of significant results may be due to short intervention duration, need for tailored content, underpowered sample, and potential indirect parent benefit from AYA participation in TMV. The parent intervention did not provide an indirect benefit for AYAs.

IMPLICATIONS FOR NURSING

Parents identified their own need for communication and support from nurses. Nurses can optimize AYA care by attending to parent needs through supportive listening and encouraging self-care.

Sequential multiple assignment randomized trial studies should report all key components: a systematic review

OBJECTIVE

Sequential Multiple Assignment Randomised Trial (SMART) designs allow multiple randomisations of participants; this allows assessment of stage-specific questions (individual randomisations) and adaptive interventions (i.e. treatment strategies). We assessed the quality of reporting of the information required to design SMART studies.

STUDY DESIGN AND SETTING

We systematically searched four databases (PubMed, Ovid, Web of Science and Scopus) for all trial reports, protocols, reviews, and methodological papers which mentioned SMART designs up to June 15, 2020.

RESULTS

Of the 157 selected records, 12 (7.64%) were trial reports, 24 (15.29%) were study protocols, 91 (58%) were methodological papers, and 30 (19.1%) were review papers. All these trials were powered using stage-specific aims. Only four (33.33%) of these trials reported parameters required for sample size calculations. A small number of the trials (16.67 %) were interested in determining the best embedded adaptive interventions. Most of the trials did not report information about multiple testing adjustment. Furthermore, most of records reported designs that were mainly focused on stage-specific aims.

CONCLUSIONS

Some features of SMART designs are seldomly reported and/or used. Furthermore, studies using this design tend to not adequately report information about all the design parameters, limiting their transparency and interpretability.

A SMART design to determine the optimal treatment of chronic pain among military personnel

Chronic pain is a leading cause of disability among active duty service members in the U.S. armed forces. Standard rehabilitative care and complementary and integrative health therapies are used for chronic pain rehabilitation. However, the optimal sequence and duration of these therapies has yet to be determined. This article describes a sequential multiple assignment randomized trial (SMART) protocol being used to identify the optimal components and sequence of standard rehabilitative care and complementary and integrative health therapies for reducing pain impact and improving other patient outcomes. Active duty service members referred to Madigan Army Medical Center for treatment of chronic pain are being recruited to the Determinants of the Optimal Dose and Sequence of Functional Restoration and Integrative Therapies study. Study participants are randomized to either standard rehabilitative care (physical and occupational therapy and psychoeducation) or complementary and integrative health therapies (chiropractic, acupuncture, yoga and psychoeducation). Those participants who do not respond to the first 3 weeks of treatment are randomized to receive an additional 3 weeks of either (1) the alternative treatment or (2) the first-stage treatment plus the alternative treatment. This study will also determine factors associated with treatment response that can support clinical decision making, such as baseline fitness, pain catastrophizing, kinesiophobia, post-traumatic stress, pain self-efficacy, and biological indicators. The information gained from this research will be applicable to all integrative chronic pain rehabilitation programs throughout the U.S. Department of Defense and the U.S. Department of Veterans Affairs, and the broader rehabilitation community.

Past is prologue: how to advance caregiver interventions

OBJECTIVES

Research on caregiving interventions has increased substantially in recent years. Although many promising approaches have been tested, results are often modest. The goal of this paper is to identify conceptual and methodological issues that could lead to better treatment outcome.

METHOD

A critical review of the literature on interventions for caregivers of persons with dementia.

RESULTS

A fundamental issue in caregiver interventions is what are appropriate goals for treatment and what outcome measures should be used to address those goals. There also needs to be more testing of the mechanisms by which treatment leads to improvement. Intervention studies should also more regularly examine fidelity of treatment implementation.

CONCLUSION

Recommendations are made for improving the design of future trials through better attention to the heterogeneity of the caregiving population, improved conceptualization of goals and the use of innovative designs that accommodate differences in caregivers' needs and resources.

A training program for nurse scientists to promote intervention translation

BACKGROUND

To reduce the burden of chronic illness, prevention and management interventions must be efficacious, adopted and implemented with fidelity, and reach those at greatest risk. Yet, many research-tested interventions are slow to translate into practice.

PURPOSE

This paper describes how The University of North Carolina at Chapel Hill School of Nursing's NINR-funded institutional pre- and postdoctoral research-training program is addressing the imperative to speed knowledge translation across the research cycle.

METHODS

The training emphasizes six research methods ("catalysts") to speed translation: stakeholder engagement, patient-centered outcomes, intervention optimization and sequential multiple randomized trials (SMART), pragmatic trials, mixed methods approaches, and dissemination and implementation science strategies. Catalysts are integrated into required coursework, biweekly scientific and integrative seminars, and experiential research training. Trainee and program success is evaluated based on benchmarks applicable to all PhD program students, supplemented by indicators specific to the catalysts. Trainees must also demonstrate proficiency in at least two of the six catalysts in their scholarly products. Proficiency is assessed through their works in progress presentations and peer reviews at T32 integrative seminars.

DISCUSSION

While maintaining the emphasis on theory-based interventions, we have integrated six catalysts into our ongoing research training to expedite the dynamic process of intervention development, testing, dissemination and implementation.

CONCLUSIONS

Through a variety of training activities, our research training focused on theory-based interventions and the six catalysts will generate future nurse scientists who speed translation of theory-based interventions into practice to maximize health outcomes for patients, families, communities and populations affected by chronic illness.

Using SMART design to improve symptom management among cancer patients: A study protocol

In this in-progress sequential multiple assignment randomized trial (SMART), dyads of solid tumor cancer patients and their caregivers are initially randomized to 4 weeks of reflexology or meditative (mindfulness) practices provided by/with their caregiver in the patient's home or to a control group. After 4 weeks, intervention group dyads in which patients do not show improvement in fatigue (non-responders) are re-randomized to either receive additional time with the same therapy during weeks 5-8 or to add the other therapy. The aims are (1) to compare reflexology and meditative practices groups during weeks 1-4 on patients' fatigue severity, summed symptom inventory score, depressive symptoms, and anxiety, so as to determine the relative effectiveness of these therapies and the characteristics of responders and non-responders to each therapy. (2) Among reflexology non-responders based on fatigue score at week 4, to determine patient symptom outcomes when meditative practices are added during weeks 5-8, versus continuing with reflexology alone. (3) Among meditative practices non-responders based on fatigue score at week 4, to determine patient symptom outcomes when reflexology is added during weeks 5-8, versus continuing with meditative practices alone. (4) To compare improvements in patient symptom outcomes among the three groups created by the first randomization. (5) To explore which dyadic characteristics are associated with optimal patient symptom outcomes, to determine tailoring variables for decision rules of future interventions. The trial has a target of 331 dyads post-attrition and has 150 dyads enrolled. We are overcoming challenges with dyadic recruitment and retention while maintaining fidelity.

Mind-Body Therapies in Individuals With Dementia: An Integrative Review

Mind-body therapies frequently derive from Eastern philosophies and are becoming increasingly popular. These therapies, such as meditation, yoga, tai chi, qigong, biofield therapies, and guided imagery, have many reported benefits for improving symptoms and physiological measures associated with various chronic diseases. However, clinical research data concerning the effectiveness of these practices in individuals with dementia have not been evaluated using a synthesis approach. Thus, an integrative review was conducted to evaluate studies examining the efficacy of mind-body therapies as supportive care modalities for management of symptoms experienced by individuals with dementia. Findings from the studies reviewed support the clinical efficacy of mind-body practices in improving behavioral and psychological symptoms exhibited by individuals with dementia.
