Participant Flow

Implementation was facilitated through the Wake Forest National Cancer Institute Community Oncology Research Program (NCORP), developed to increase community participation in cancer trials. Forty-six participants were accrued between July 30 2015 and June 11 2019 (0.99 participants/month).

In this feasibility study, participants were stratified by baseline self-reported dyspnea score and randomized to a 12-week high-dose or low-dose device-guided breathing intervention versus a usual breathing control group with equal probability, using variable length permuted block randomization. All participants enrolled were randomized and included in analyses.

PRIMARY outcome

Timeframe: 12 weeks

Population: Adherence data used visits up to withdrawal or study completion. Includes 5 participants missing all breathing visits. Excludes 2 participants that withdrew at baseline and have no available data.

Adherence will be calculated as the actual amount of time the device is used divided by the prescribed time. Successful adherence will be defined as use of the device ≥80% of the time assigned.

PRIMARY outcome

Timeframe: Time from study opening to study close ~46.42 months

Population: Participants were accrued between July 30 2015 and June 11 2019 for a total of 46.42 months.

The accrual rate will be calculated as the number of patients accrued to the study divided by the number of months of accrual.

SECONDARY outcome

Timeframe: 12 weeks

Population: All data was utilized.

To obtain preliminary data on the variability and efficacy of two doses of a device-guided breathing intervention versus a usual breathing control group for reducing anxiety. This is a 14-item self-report measure of cognitive and behavioral symptoms of anxiety and depression; clinically significant symptoms are indicated by a score of greater than or equal to 8 with a range from 0 to 42. Higher scores indicate more anxiety.
