Adverse technical events in home hemodialysis

Area of Science:

• Nephrology
• Patient Safety
• Medical Technology

Background:

• Home hemodialysis offers clinical benefits but requires patients to manage complex procedures.
• Ensuring patient safety through adverse event reporting is crucial for home hemodialysis.
• This study focuses on technical adverse events in a large home hemodialysis cohort.

Purpose of the Study:

• To describe the incidence and nature of adverse technical events in home hemodialysis patients.
• To identify common causes of adverse events in home hemodialysis.
• To assess the rate of severe adverse events requiring intervention.

Main Methods:

• Retrospective cohort study design.
• Analysis of consecutive home hemodialysis patients from 1999-2011.
• Evaluation of adverse event rates per access type and per dialysis treatment.

Main Results:

• The study included 202 patients with 757 patient-years of follow-up.
• Adverse event rates varied by vascular access type (fistula, graft, catheter).
• Needle dislodgement and air embolism were the most common events; severe events were rare (0.009/patient-year).

Conclusions:

• Serious adverse technical events in home hemodialysis are uncommon.
• Patient retraining and periodic vascular access audits are recommended strategies for prevention.
• Under-reporting of non-severe events by patients may occur.
