A system for preventing internal fistula needle dislodgement: Delphi study and pilot evaluation

Abstract

AbstractAimTo establish a scoring system for risk assessment (SSRA) for internal fistula needle dislodgement (IND) in hemodialysis (HD) patients.MethodsThe SSRA was constructed based on literature search, medical history review, expert consultations, expert meeting (Delphi study), and analytic hierarchy process. Then, a pilot test was conducted at our hospital between August 1, 2020, and July 30, 2021. Consecutive patients requiring HD were included and randomly assigned to experimental and control groups (1:1 ratio). Control group was treated with the routine procedures, while the experimental group was treated with strengthened nursing measures based on the individual risk assessed by SSRA. Finally, the incidence of IND was compared between the two groups.ResultsFor the Delphi study, 16 experts in dialysis nursing in Zhejiang, Shanghai, Guangzhou, and Qinghai were included. The final draft of the SSRA included three first‐level indices, 11 second‐level indices, and 26 third‐level indices. A total of 218 HD patients were included. The IND rate in the experimental group was significantly lower than that in the control group (p < .01).ConclusionWe established a scientific, reliable, and feasible SSRA for timely identification of HD patients with high risk of IND and the corresponding nursing procedures to prevent IND.
