Acceptability of a multilevel intervention to improve blood pressure control among patients with chronic kidney disease in a public health care delivery system.

backgroundThe Kidney Awareness Registry and Education (KARE) trial examined the impact of a multilevel intervention on blood pressure control among patients with chronic kidney disease (CKD) in a public health care delivery system. KARE consisted of a clinic-based intervention (a primary care CKD registry with point-of-care provider notifications and quarterly feedback related to CKD management) and a patient-directed intervention [a CKD self-management support (CKD-SMS) program that included low literacy educational materials, automated telephone-administered self-management modules and telephone health coaching]. We explored the acceptability of these interventions among end users.

methodsAt trial conclusion, we surveyed 39 primary care providers (PCPs) to identify preferences about components of the clinic intervention, conducted two focus groups among non-PCP staff to elicit in-depth attitudes and experiences with operationalizing the team-based CKD registry, and conducted eight focus groups with English- and Spanish-speaking patients to hear about their experiences with the CKD-SMS program. Focus group transcripts were analyzed using thematic analysis. Self-reported participation and data from the automated telephone program were used to evaluate patient engagement.

resultsMost PCPs (94%) believed that the point-of-care notifications benefited clinic workflow and agreed that quarterly feedback enhanced their ability to identify (89.5%) and manage (73.7%) CKD. Staff confirmed usefulness of point-of-care notifications. Patients suggested the automated telephone system was impersonal, though easy to use; that frequent automated calls were helpful to reinforce self-management behaviors; and that telephone health coaching was convenient. Nearly 40% of patients completed >80% of automated phone calls, 95% participated in calls with their health coach and 77% created at least one action plan.

conclusionsA CKD registry is acceptable to primary care health care teams and has potential to enhance identification and management of CKD in primary care. Low-income patients appreciated and engaged with a telephone-based CKD-SMS program, demonstrating its potential for increasing awareness and health engagement among populations with CKD within a public health care delivery system.
