The CATALYTIC tool to assess feasibility of implementing evidence-based interventions for cardiovascular diseases in 46 low- and middle-income countries: survey outcomes and tool reliability testing

Overall, the CATALYTIC tool with 12 reliable survey items can help researchers and implementers elucidate perceptions of contextual factors influencing the feasibility of CVD-related EBI in LMIC. The survey items reflect respondents' practical focus in resource-limited settings and can inform intervention design by addressing existing needs and barriers. The tool's integration of contextual factors into the assessment of feasibility can help overcome the inadequacy of existing instruments by providing more tailored and conceptually clear assessments of feasibility.
