Background and objectives: The population of patients with kidney failure in the United States using home dialysis modalities is growing rapidly. Unlike for in-center hemodialysis, there is no patient-reported experience measure for assessment of patient experience of care for peritoneal dialysis or home hemodialysis. We sought to develop and establish content validity of a patient-reported experience measure for patients undergoing home dialysis using a mixed methods multiple stakeholder approach.
Design, setting, participants, & measurements: We conducted a structured literature review, followed by concept elicitation focus groups and interviews among 65 participants, including 21 patients on home dialysis, 33 home dialysis nurses, three patient care partners, and eight nephrologists. We generated a list of candidate items for possible measure inclusion and conducted a national prioritization exercise among 91 patients on home dialysis and 39 providers using a web-based platform. We drafted the Home Dialysis Care Experience instrument and conducted cognitive debriefing interviews to evaluate item interpretability, order, and structure. We iteratively refined the measure on the basis of interview findings.
Results: The literature review and concept elicitation phases supported 15 domains of home dialysis care experience in six areas: communication and education of patients, concern and helpfulness of the care team, proficiency of the care team, patient-centered care, care coordination, and amenities and environment. Focus groups results showed that domains of highest importance for measure inclusion were patient education and communication, care coordination, and personalization of care. Prioritization exercise results confirmed focus group findings. Cognitive debriefing indicated that the final measure was easily understood and supported content validity.
Conclusions: The Home Dialysis Care Experience instrument is a 26-item patient-reported experience measure for use in peritoneal dialysis and home hemodialysis. The Home Dialysis Care Experience instrument represents the first rigorously developed and content-valid English-language instrument for assessment of patient-reported experience of care in home dialysis.
