Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Concordance between the recommended medical actions based on the Cardio Explorer risk class and the medical (diagnostic) procedure, both assessed during the intervention phase. The Cardio Explorer risk class is determined for each patient at one point throughout individual treatment (application of the Cardio Explorer). The medical (diagnostic) procedure determined by the GP is assessed at the end of treatment for each patient using a self-developed questionnaire (electronic Case Report Form). | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The GPs’ ratings on the benefit of facilitation of risk assessment are measured using a self-developed questionnaire at the end of treatment for each patient (electronic Case Report Form). Ratings on the benefit of the risk assessment derived from qualitative interviews with GPs at the end of the intervention phase are considered as well. 2. The confidence among GPs in the risk assessment of the Cardio Explorer measured using a self-developed questionnaire at the end of treatment for each patient (electronic Case Report Form) during the intervention phase 3. GPs' good usability and practicality (usefulness, ease of use, ease of learning and satisfaction) of the Cardio Explorer measured using the standardized USE questionnaire (Usefulness, Satisfaction and Ease of use) at the end of the intervention phase. Subjective ratings (advantages and disadvantages) regarding the implementation of the Cardio Explorer derived from qualitative interviews are considered. 4. The effects on the indication for diagnostic procedures measured via the type and number of diagnostic procedures based on claims data during the follow-up period. In addition, the subjective ratings of the GPs on the reduction of unnecessary diagnostic procedures derived from qualitative interviews at the end of the intervention phase are considered. 5. The effects on the demand for treatment by cardiologists are measured by the number of patient visits to cardiologists based on claims data (follow-up period) as well as subjective ratings among GPs derived from qualitative interviews at the end of the intervention phase. | — |
