Clinical Trial Summary

A pilot feasibility study of a small randomized controlled trial (RCT) comparing a video-conferencing cognitive behavioral coping skills (VC-CBCS) group to standard of care (SC) for symptomatic patients previously diagnosed with chronic hepatitis C to evaluate feasibility, patient satisfaction and differences in symptoms, quality of life and liver markers.

Description:

This is a pilot feasibility study of a small randomized controlled trial (RCT) to evaluate a cognitive behavioral coping skills (CBCS) delivered via videoconferencing, referred to as the "VC-CBCS" compared to standard of care (SC). The study included a representative sample of 32 symptomatic patients who have/had chronic hepatitis C. Patients (n=32) were randomized in a 1:3 ratio to (1) standard of care (SC) or (2) to participate in 14, two hour VC-CBCS sessions. Four groups of patients were randomized and consisted of 7-9 patients each. The groups were as follows:

• Group 1: 7 patients with 5 randomized to VC-CBCS and 2 to SC;

• Group 2: 9 patients with 7 randomized to VC-CBCS and 2 to SC;

• Groups 3 and 4: 8 patients each with 6 randomized to VC-CBCS and 2 to SC each group.

Each wave of VC-CBCS patients formed a group to join the Group Facilitator via a WebEx platform on a weekly basis using iPads from their homes. The telehealth intervention provided group-based education, skills and practices involving stress management, coping with symptoms, and support for healthy lifestyle changes. The researchers examined: (1) the feasibility of delivering a group intervention via telehealth technology remotely using iPads, (2) participant satisfaction with the intervention, and (3) whether differences are observed in several outcomes between the two conditions on quality of life, physical and mental symptoms, and liver markers. Participants completed patient-reported outcome (PRO) surveys at four time points during the study, with main outcomes being change from pre-intervention to post-intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Salivary Cortisol Area Under the Curve With Respect to Ground (AUC-G)	Participants in both conditions collected saliva samples at Baseline (T1) and Week 14 (T4). Participants were instructed to collect four saliva samples at each timepoint; 1) immediately upon awakening 2) 30 minutes after awakening 3) late afternoon 4) before bedtime. The mean AUC-G was then obtained at T1 and T4. Mean AUC-G scores could range from 0.195 to 2.29.	Baseline (T1), Week 14 (T4)
Other	Participant Satisfaction With VC-CBCS Telehealth Session Mean Score	After intervention week 1 and week 14, participants in the VC-CBCS intervention completed a 15-item acceptability/satisfaction survey about their satisfaction with using telehealth sessions. Items were scored on a scale from 1= strongly disagree to 5=strongly agree. The average Total Telehealth Satisfaction score from week 1 and week 14 was created, which ranged from 1 to 5 with higher scores indicating greater satisfaction. A previously developed Telehealth Patient Satisfaction Questionnaire was modified for this study.	Baseline (T1) to Week 14 (T4)
Primary	Percentage of Patients Consented Versus Approached	One feasibility measure was to evaluate the percentage of patients consented compared to those approached for participation in the study.	Six Months
Primary	Percentage of Participants Consented Versus Randomized	One feasibility measure was to evaluate the percentage of participants randomized for the study compared to those consented.	Six Months
Primary	Percentage of Standard of Care Condition Participants Retained vs Enrolled	Percentage of standard of care condition participants retained in the study compared to those enrolled. Retention is defined as participants who submitted PRO assessments up through T4 (end of study).	Six Months
Primary	Percentage of VC-CBCS Intervention Condition Participants Retained vs Enrolled	Percentage of VC-CBCS Intervention participants retained in the study compared to those enrolled. Retention is defined as participants who completed at least 3 intervention sessions.	Six Months
Primary	Percentage of Surveys Completed by Participants Who Completed the Study	Percentage of surveys over time completed by participants who completed the study. Surveys included 12 patient-reported primary and secondary outcome measures. Completion was defined as submission of each of the 12 surveys at Time 1 (T1) through Time 4 (T4).	Baseline (T1) to Week 14 (T4)
Primary	Global Health Status Physical Health Mean T-Score	The Patient Reported Outcome Measurement Information System (PROMIS) Global Health Status measure is a 10-item short form that was used to measure an individual's physical, mental, and social health. Item responses range from 5 = None to 1 = Very Severe. The adult PROMIS Global Health measure produces two scores: Physical Health and Mental Health. The raw scores are converted into a T-score. T-Score distributions are standardized such that a 50 represents the average (mean) for the US general population, and the standard deviation around that mean is 10 points. The minimum and maximum T-scores ranged from 16.2 to 67.7. Higher T- scores indicate more of that construct, for example, a T-score=60 is 1 standard deviation better (more healthy) than the general population.	Baseline (T1), Week 14 (T4)
Primary	Global Health Status Mental Health Mean T-Score	The PROMIS Global Health Status measure is a 10-item short form that was used to measure an individual's physical, mental, and social health.

T-Score distributions are standardized such that a 50 represents the average (mean) for the US general population, and the standard deviation around that mean is 10 points. The minimum and maximum T-scores ranged from 21.2 to 67.7.
