Feasibility and Acceptability of Using an Evidence-Based Tai Chi Intervention for Managing the Fatigue–Sleep Disturbance–Depression Symptom Cluster in Breast Cancer Patients

TL;DR

This study shows that Tai Chi is a feasible and acceptable non-drug method for managing fatigue, sleep issues, and depression in breast cancer patients.

Contribution

The study demonstrates the feasibility and acceptability of an evidence-based Tai Chi intervention for managing a specific symptom cluster in breast cancer patients.

Findings

The Tai Chi intervention had a high recruitment rate (79.1%) and retention rate (95.8%) over six months.

Participants reported minor and manageable side effects, with high adherence (86.8%) to the Tai Chi protocol.

Qualitative feedback indicated that Tai Chi was perceived as convenient, low-intensity, and beneficial for symptom management.

Abstract

Objective: To explore the feasibility and acceptability of using an evidence-based Tai Chi intervention to manage the fatigue–sleep disturbance–depression symptom cluster (FSDSC) in female breast cancer patients. Methods: This study reported the feasibility outcomes of a pilot randomized controlled trial (RCT), along with a nested qualitative process evaluation. Seventy-two female breast cancer patients experiencing the FSDSC were randomized into either a Tai Chi group or a control group. The Tai Chi group received an eight-week Tai Chi intervention consisting of two one-hour sessions per week, along with routine care, while the control group received routine care only. The feasibility and acceptability of the study procedure and Tai Chi intervention protocol were assessed by measuring recruitment, referral, retention and drop-out rates, questionnaire completion rates (including the Brief Fatigue Inventory [BFI], Pittsburgh Sleep Quality Index [PSQI], Hospital Anxiety and Depression Scale-Depression [HADS-D], and Functional Assessment of Cancer Therapy-Breast [FACT-B]), intervention adherence, and safety outcomes. The nested qualitative process evaluation consisted of semi-structured interviews conducted among 22 participants to further explore their experiences of participating in this study and practicing Tai Chi. Descriptive data analysis was employed to present the feasibility and acceptability outcomes. Content analysis was employed to analyze the data from the qualitative process evaluation. Results: A total of 72 breast cancer patients were successfully recruited over six months, with a recruitment rate of 79.1%, retention rate of 95.8%, and dropout rate of 4.2%. No missing data was found in the BFI, PSQI, or HADS-D. However, a notable number of missing values were found in the FACT-B, particularly for items related to sexual satisfaction. The Tai Chi intervention demonstrated a high level of feasibility, with an average adherence rate of 86.8%. Only eight participants reported minor discomforts, such as minor musculoskeletal discomfort and dizziness, but they were transient and manageable after stopping Tai Chi practice. Semi-structured interviews with 22 participants highlighted that Tai Chi was experienced to be generally convenient, energy-saving, and low intensity for FSDSC management. Participants also felt that the study questionnaires were comprehensible and straightforward. Many interviewees from the Tai Chi group reported perceiving favorable effects on FSDSC management, as well as overall functional health and well-being. Conclusions: The evidence-based Tai Chi intervention proved feasible, safe, and convenient as a non-pharmacological intervention for managing FSDSC in breast cancer patients. Future large-scale studies are needed to evaluate Tai Chi’s definite effects on improving FSDSC among breast cancer patients.
