Modifying a generic postoperative recovery profile instrument to an instrument specifically targeting coronary artery...

Patients may suffer from a wide range of postoperative symptoms after coronary artery bypass grafting. In-depth knowledge of the recovery process is a prerequisite for nursing interventions. However, we found no specific instrument covering the entire range and duration of postoperative symptoms related to this procedure. We therefore modified and extended the 19 items, generic Postoperative Recovery Profile questionnaire for the specific evaluation of the recovery after coronary artery bypass grafting. We here report on the development process of the new questionnaire. Procedure-specific symptoms were identified by a literature review and by experts. The content validity was assessed by healthcare professionals (n = 15), inpatients (n = 12) and outpatients (n = 4). A test run was done with inpatients (n = 10), which was followed by a test-retest reliability evaluation with inpatients (n = 24). We identified 15 new symptoms in the literature review and six in the content validity assessment. Only three of the 35 items had an acceptable content validity index, but all 35 items in the test run were reported by at least two patients. The questionnaire took 4-9 minutes to complete and was considered easy to use. The final instrument used in the reliability test included 22 new items, and 25 of the 35 items were satisfactory stable. To conclude, we developed a 35 items, procedure-specific questionnaire that was easy to use and may aid systematic assessment of the recovery after coronary artery bypass grafting.
