Targeting Patient and Health System Barriers To Improve Rates of Hemodialysis Initiation with an Arteriovenous Access.

BACKGROUND: Guidelines recommend pre-emptive creation of arteriovenous (AV) access. However, <20% of US patients initiate hemodialysis (HD) with a functional AV access. We implemented a quality improvement (QI) program to improve pre-HD vascular access care. METHODS: After conducting qualitative research with key informants, we implemented a 7-month vascular access support QI program at Geisinger Health. The program targeted patient and health system barriers to AV access through education, needs assessment, peer support, care navigation, and electronic supports. We performed pre-, intra-, and postprogram stakeholder interviews to identify program barriers and facilitators and to assess acceptability. In a research substudy, we compared pre- and postprogram self-efficacy, knowledge, and confidence navigating vascular access care. RESULTS: There were 37 patient and 32 clinician/personnel participants. Of the 37 patients, 34 (92%) completed vascular access-specific education, 33 (89%) underwent needs assessment, eight (22%) engaged with peer mentors, 21 (57%) had vein mapping, 18 (49%) had an initial surgical appointment, 15 (40%) underwent AV access surgery, and six (16%) started HD during the 7-month program. Qualitative findings demonstrated program acceptability to participants and suggested that education provision and emotional barrier identification were important to engaging patients in vascular access care. Research findings showed pre- to postprogram improvements in patient self-efficacy (28.1-30.8, P=0.05) and knowledge (4.9-6.9, P=0.004), and trends toward improvements in confidence among patients (8.0-8.7, P=0.2) and providers (7.5-7.8, P=0.1). CONCLUSIONS: Our intervention targeting patient and health system barriers improved patient vascular access knowledge and self-efficacy.
