Increasing Adherence to Pulmonary Rehabilitation After COPD Related Hospitalizations (Study 2)

The number of subjects who completed PR through 3 months

The Chronic Respiratory Questionnaire (CRQ) is a validated tool that is completed by participants at baseline and 3 months, measuring health-related quality of life. This questionnaire measures both physical and emotional aspects of chronic respiratory disease. We reported the difference between baseline and 3 months on the CRQ emotional summary scores (comprised of the summation of the mastery and emotional domains of CRQ divided by 2) and the physical summary score (comprised of the summation of the dyspnea and fatigue domains of the CRQ divided by 2). Summary scores as well as the original domains , all have a range of 1 to 7 points, with a higher number being a better health-related quality of life. 0.5 points is the minimal clinically important difference for this tool. Then, for the interpretation of CRQ results: a difference>0.5 is considered clinically meaningful

The EuroQol (EQ-5D) is a 5-item questionnaire that assesses health-related quality of life over five different dimensions of health: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. It also includes a Visual Analogue Scale (VAS) for self-related heath. Each dimension uses a 5-level Likert scale (1 = no problems, 5 = extreme problems), ensuring nuanced data collection. The VAS ranges from 0 (worst imaginable health) to 100 (best imaginable health). Scores are calculated for each dimension with total scores ranging from 1 (no problems) to 5 (extreme problems), with higher scores indicating a worse outcome. The score from the VAS portion of the questionnaire ranges from 0 (worst imaginable health) to 100 (best imaginable health), with higher scores indicating a better outcome.

The number of subjects who had at least one Emergency Department visit from baseline to 3 months.

The number of subjects who had at least one hospitalization from baseline to 3 months.

Measured using the Self-Management Ability Scale-30 item questionnaire to assess ability and function. The SMAS consists of 30 items on four- and five-point Likert scales. Total score ranging from 0 to 100 with higher score indicating a higher function and ability, better outcome.

Participants wore an Actigraph Activity Monitor for one week to measure daily steps.

Participants wore an Actigraph Activity Monitor for one week to measure daily time spent doing sedentary (low energy expenditure) and non-sedentary (high energy expenditure) activities.

The Duke-UNC Functional Social Support Questionnaire is an 8-item questionnaire that measures the amount of social support and availability of help from family and friends. The answers range from 1 "Much less than I would like" to 5 " As much as I would like". The scores from all 8 questions are summed (maximum 40) and then divided by 8 to get an average score. The higher the average score, the greater the perceived social support.
