Changes made to the CROQ instrument or administration of it
| Type of change | CROQv13 | NHS Coronary Revascularisation PROMs Pilot |
|---|---|---|
| Textual changes | – | Owing to changes in clinical practice over time, PCI is now often performed via the radial artery rather than the femoral artery in the groin. Textual changes were necessary for all items in the CROQ-PCI adverse effects scale. |
| Assessment point | Validated for use with patients at pre-coronary and 3-months post-coronary revascularisation. | The postrevascularisation assessment point (Q2) was changed to 6 months postrevascularisation. |
| Method of administration | Prerevascularisation and postrevascularisation versions were administered by postal survey. | Prerevascularisation questionnaires were administered in the clinical setting by staff with assistance provided as required. The reason for requiring assistance will have varied, for example, some patients might not have been able to read English and others might just have needed help interpreting a single item. |
| Setting | Prerevascularisation and postrevascularisation versions administered by postal survey to patients’ home addresses. This enabled patients to complete the questionnaires at leisure and privately outside of the clinical setting. | Prerevascularisation questionnaires were administered in the clinical setting with assistance provided by staff for those requiring it. |
| Sampling frame | English speaking patients undergoing elective coronary revascularisation procedures at three hospitals in the UK. | Patients undergoing elective procedures at 11 hospitals in the UK with a potentially different case mix severity and demographic profile. Patients speaking all languages were offered the prerevascularisation questionnaire by staff in the clinical setting. Staff offered to assist patients, for example, by reading the questions to patients and explaining the meaning and a telephone translation service was available on request. |
