Intervention fidelity in Qigong randomized controlled trials: A method review

Intervention Fidelity to VITAL Start (Video Intervention to Inspire Treatment Adherence for Life) in a Randomized Controlled Trial Among Women Living With HIV in Malawi

BACKGROUND.

Intervention effectiveness in a randomized controlled trial is attributed to intervention fidelity. Measuring fidelity has increasing significance to intervention research and validity. The purpose of this article is to describe a systematic assessment of intervention fidelity for VITAL Start (Video intervention to Inspire Treatment Adherence for Life)-a 27-minute video-based intervention designed to improve antiretroviral therapy adherence among pregnant and breastfeeding women.

METHOD.

Research Assistants (RAs) delivered VITAL Start to participants after enrolment. The VITAL Start intervention had three components: a pre-video orientation, video viewing, and post-video counseling. Fidelity assessments using checklists comprised self (RA assessment) and observer (Research Officers, also known as ROs) assessment. Four fidelity domains (adherence, dose, quality of delivery, and participant responsiveness) were evaluated. Score scale ranges were 0 to 29 adherence, 0 to 3 dose, 0 to 48 quality of delivery and 0 to 8 participant responsiveness. Fidelity scores were calculated. Descriptive statistics summarizing the scores were performed.

RESULTS.

In total, eight RAs delivered 379 VITAL Start sessions to 379 participants. Four ROs observed and assessed 43 (11%) intervention sessions. The mean scores were 28 (SD = 1.3) for adherence, 3 (SD = 0) for dose, 40 (SD = 8.6) for quality of delivery, and 10.4 (SD = 1.3) for participant responsiveness.

CONCLUSION.

Overall, the RAs successfully delivered the VITAL Start intervention with high fidelity. Intervention fidelity monitoring should be an important element of randomized control trial design of specific interventions to ensure having reliable study results.

Simple Sitting Baduanjin mind-body exercise: randomized controlled trial protocol for advanced cancer patients with the fatigue-sleep disturbance symptom cluster

BACKGROUND

Advanced cancer patients commonly suffer from a fatigue-sleep disturbance symptom cluster. Baduanjin is considered a promising mind-body exercise for relieving the fatigue-sleep disturbance symptom cluster. However, few studies have investigated a tailored Baduanjin for advanced cancer patients. The proposed study will create an optimized Baduanjin exercise program to adapt to advanced cancer patients and evaluate the effect of a Simple Sitting Baduanjin (SSBDJ) mind-body exercise on the fatigue-sleep disturbance symptom cluster among advanced cancer patients.

METHODS

The study will be a prospective, assessor-blinded, two-arm, randomized controlled trial, involving a 12-week intervention and 4-week follow-up. A total of 108 advanced cancer patients experiencing the fatigue-sleep disturbance symptom cluster will be recruited from two tertiary general hospitals in China. Participants will be randomized to an experimental group (n = 54) or a control group (n = 54). The experimental group will receive a 12-week SSBDJ intervention plus the usual care, and the control group will receive only the usual care. Outcomes including fatigue-sleep disturbance symptom cluster, fatigue, sleep disturbance, and quality of life will be measured before the intervention, at the 4th, 8th, and 12th weeks of the intervention, and 4 weeks after the intervention. The intention-to-treat principle and a generalized estimating equation will be used to analyze data.

DISCUSSION

This study may produce a new Baduanjin exercise prescription that is user-friendly, simple to execute, more targeted, and adaptable. If proven effective, this approach may be integrated into routine cancer care to manage the fatigue-sleep disturbance symptom cluster and improve QOL in advanced cancer patients.

A pilot randomized clinical trial examining the effects of Qigong on inflammatory status and sleep quality in people with Parkinson's disease

BACKGROUND

Neuroinflammation contributes to degeneration of neurons in people with Parkinson's disease (PD). The concentrations of inflammatory cytokines, IL-1β, IL-6, and TNF-α, are often increased in people with PD and are associated with various non-motor symptoms. Qigong exercise is a mind-body practice which has been used as a rehabilitation intervention for people with PD. A previous study showed a strong association between sleep quality and inflammatory status. This study investigated the effect of Qigong on inflammatory status in people with PD and explored potential relationships between inflammatory status and sleep quality in this population.

METHODS

The study was a randomized controlled trial. A total of 17 participants completed the 12-week intervention (Qigong (n = 8), sham Qigong (n = 9)). Questionnaires were utilized to assess non-motor symptoms, including sleep quality. Inflammatory cytokines were measured by a high sensitivity antibody-based multiplex assay.

RESULTS

After the 12-week intervention, a decreasing trend in the concentrations of IL-1β and IL-6 was found in the Qigong group. Moderate to strong correlations were found between changes in IL-1β concentrations and sleep quality.

CONCLUSION

Inflammation is an important aspect of PD. This study explored the inflammatory status after a mind-body exercise. Further studies need to extend our findings to confirm the effect of Qigong in people with PD.

Benefits of Qigong as an integrative and complementary practice for health: a systematic review

Objective:

to analyze, in the literature, evidence about the benefits of the integrative and complementary practice of Qigong with regard to the health of adults and the elderly.

Method:

a systematic review by searching for studies in the PubMed, CINAHL, LILACS, EMBASE and Cochrane Library databases. Randomized and non-randomized clinical trials were included; in Portuguese, English and Spanish; from 2008 to 2018. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses strategy was adopted, as well as the recommendation of the Cochrane Collaboration for assessing the risk of bias in the clinical trials analyzed.

Results:

28 studies were selected that indicated the benefit of the practice to the target audience, which can be used for numerous health conditions, such as: cancer; fibromyalgia; Parkinson’s disease; Chronic Obstructive Pulmonary Disease; Burnout; stress; social isolation; chronic low back pain; cervical pain; buzz; osteoarthritis; fatigue; depression; and cardiovascular diseases. However, there was a great risk of bias in terms of the blinding of the research studies.

Conclusion:

the practice of Qigong produces positive results on health, mainly in the medium and long term. This study contributes to the advancement in the use of integrative and complementary practices in nursing, since it brings together the scientific production in the area from the best research results available.

Can Qigong improve non-motor symptoms in people with Parkinson's disease - A pilot randomized controlled trial?

Non-motor symptoms (NMS) including sleep disorders, anxiety, depression, fatigue, and cognitive decline can significantly impact quality of life in people with PD. Qigong exercise is a mind-body exercise that shows a wide range of benefits in various medical conditions. The purpose of this study was to investigate the effect of Qigong exercise on NMS with a focus on sleep quality. Seventeen participants completed a 12-week intervention of Qigong (n = 8) or sham Qigong (n = 9). Disease severity, anxiety and depression levels, fatigue, cognition, quality of life, and other NMS of the participants were evaluated prior to the intervention and at the end of the 12-week intervention. After the intervention, both Qigong and sham-Qigong group showed significant improvement in sleep quality (p < 0.05) and overall NMS (p < 0.05). No significant difference was found between groups. Qigong exercise has the potential as a rehabilitation method for people with PD, specifically alleviating NMS in PD. However, this finding needs to be carefully considered due to the small sample size and potentially low intervention fidelity of this study.

Move-It: A Cluster-Randomised Digital Worksite Exercise Intervention in China: Outcome and Process Evaluation

We evaluate the outcomes and processes of a video and web-based worksite exercise intervention for sedentary office workers in China, in a 2-arm cluster-randomised wait-list control trial (n = 282: intervention (INT) n = 196 and wait-list control (WLC) n = 86). Eligible clusters were two sites of a major organisation in China randomly allocated to each group (INT: Guangzhou; WLC: Beijing); eligible participants were site employees (n = 690). A theoretically informed digital workplace intervention (Move-It) involving a 10 min Qigong exercise session (video demonstration via website) was delivered twice a day at set break times during the working day for 12 consecutive weeks. Individual-level outcomes were assessed. Participants' physical activity increased significantly from baseline to post-intervention similarly in both the intervention and the control group. There was a significantly smaller increase in weekday sitting hours in intervention than controls (by 4.66 h/week), and work performance increased only in the control group. Process evaluation (including six focus groups) was conducted using the RE-AIM (reach, effectiveness, adoption, implementation and maintenance) framework. The intervention had wide reach and was successfully marketed to all employees with good uptake. The participatory approach increased perceived organisational support and enhanced adoption. The intervention was implemented broadly as planned. Qigong worksite exercise intervention can be successfully delivered to sedentary office workers in China using video and web-based platforms. It may increase physical activity and does not adversely affect perceived work performance. The study highlights the complexity of conducting health promotion research in real-world organisational settings.
