Table 3 Reach, Effectiveness, Adoption and Implementation (RE-AIM) framework indicators
Domain | Indicators | Source | Data Collection Tool |
|---|---|---|---|
Reach | Participation rate | Participants & Disease management system | Enrolled couples /all couples being contacted |
Representativeness | Enrolled couples / all eligible couples registered in the system | ||
Effectiveness | Health outcomes | Participants | HbA1c, Quality of life, BMI, WC, blood pressure, fasting glucose & lipid profile; management and healthy behaviors (exercise, diet) |
Adoption | Number of health workers who prefer couple-based over individual-based interventions | Community health workers | Qualitative interview and survey of community health workers |
Implementation | Treatment fidelity | Randomly selected taped sessions | 10% of taped sessions randomly selected and reviewed by an expert panel, against the full detailed intervention manuals for adherence and quality. |
Participant involvement | Participants | Course registration forms recording attendance rate | |
Participant satisfaction | Participants | Satisfaction questionnaire on the program, from 1 (strongly disagree) to 4 (strongly agree). | |
Incremental cost- effectiveness ratio (ICER) of the intervention and control arms | Participants | ICER = ∆C/∆E = (Cintervention − Ccontrol)/ (Eintervention – Econtrol); C is the program and labor costs; E is effectiveness defined as the percentage of patients whose HbA1c is lower than 7% | |
Maintenance | Effectiveness over 1Â year | Participants | Same as effectiveness. |
