Community Health Worker-Led Intervention to Increase Cardiac Rehabilitation Participation

Proportion enrolled in the H2H among those eligible and approached, and Proportion who complete 4 H2H sessions or enroll in CR

Questionnaire:

Scores on questionnaire to assess satisfaction. Questions are rated on a Likert scale from 1 (not at all) 5 extremely. There are 6 questions in the rating of the overall program with a total score range 6-30. Acceptability cutoff will be proportion of participants with score ≥ 18. There are 4 questions on the H2H coaching sessions and CHW. The maximum and minimum scores are 4 and 20 respectively. Acceptability cutoff will be proportion of participants with scores ≥ 12.

A semi-structured interview will be conducted by the research team about the H2H Program overall, and about the coaching sessions with the CHW, to determine the participants' perceptions of the degree to which the intervention was engaging, feasible, acceptable and useful. Recommendations for improving the H2H Program will be solicited. The interviews will take approximately 30-45 minutes. The interviews will be transcribed and analyzed for themes and codes

Change in Cardiac Rehab Barriers Scale: 21-item questionnaire that assesses participants perceptions of barriers to CR. Each item is rated on a 5-point Likert Scale, with 1 indicating strong disagreement and 5 indicating strong agreement. This is a validated scale. Score range 21- 105. Higher scores indicate greater barriers to patient enrollment or participation in a CR program.

13-item questionnaire that assess participant's knowledge, skills, and confidence in managing their own health and healthcare. It is a validated patient related outcome measure. Each item rated on 4-point scale (1 strongly disagree to 4 strongly agree, with additional "not applicable" option). Score range is 13-52. Then, this score is transformed to a scale with a theoretical range 0-100, based on calibration tables, with higher Patient activation measure 13 (PAM13) scores indicating higher patient activation

(Preliminary Efficacy) Total number of CR sessions attended. This can range from 0 to 36.

(Process Measures of Content Delivery) Number of CHW sessions contacts, where content is delivered, extra contacts, numbers of contacts attempted, number of contacts completed

(Process Measures of Content Delivery) Duration of coaching session

(Process Measures of Content Delivery) Number of CHW sessions contacts attempted

(Process Measures of Content Delivery) Number of CHW sessions contacts completed

Change in mean score on the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Scale

PROMIS is a 10-item questionnaire that measures a person's global physical and mental health. This is a validated scale.

Uses a 5-point Likert scale for most items, with a pain intensity item scored on a 0-10 scale (then recoded to a 5-point scale), to assess physical, mental, and social health, producing Global Mental and Physical Health scores.

The score range for the PROMIS Global Health scales is 0- 100. Higher scores are better.

Change in mean score on the Patient Health Questionnaire (PHQ)-8

8-item scale that measures depressive symptoms over the past two weeks.

Each of the eight items on the PHQ-8 is scored on a scale of 0 to 3, with 0 representing "not at all" and 3 representing "nearly every day"

The total score is calculated by adding up the scores from each of the eight items, resulting in a possible score range of 0 to 24

A score of 5-9 indicates mild depressive symptoms, 10-14 moderate, 15-19 moderately severe, and 20-24 severe.

Change in mean score on the Generalized Anxiety Disorder (GAD7)

GAD7 is a 7-item scale those measures anxiety symptoms over the past few days, from not at all to nearly every day.

Each of the 7 items is scored from 0 to 3, with higher scores indicating greater severity of anxiety symptoms

A score of 5-9 indicates mild anxiety, 10-14 moderate, 15-19 moderately severe, and 20-21 severe anxiety

The Generalized Anxiety Disorder-7 (GAD-7) scale has a maximum score range of 0- 21.

Change in mean score on the Perceived Stress Scale (PSS10).

PSS-10: The PSS-10 is a 10-item questionnaire where each item is scored on a 5-point Likert scale (0 = never, 4 = very often).

The score range on the Perceived Stress Scale (PSS) is 0-40, with higher scores indicating greater perceived stress.

Change in total score on the Telephone Assessment of Physical Activity (TAPA)

9-item questionnaire that asks the frequency, intensity, and duration of physical activity. This is a validated scale.

Each question has a 'Yes' or 'No' option. The total score of the first seven items is out of 7; participants choose which question corresponds to their activity level. Any score less than 6 is considered suboptimal. Strength training and flexibility are scored separately (strength training = 1, flexibility = 2, both = 3)
