Educational or Behavioural Interventions to Improve Long-Term Haemodialysis Vascular Access Self-Management: A Systematic Review.

Only seven studies were found, and they were very different in design, participants, interventions and outcome measures, so the review could not combine them statistically. Most studies were quasiexperimental; the two randomised trials did not report blinding, allocation concealment or intention-to-treat analysis. Several studies had no control group, and most education was mixed with broader dialysis teaching, so the contribution of vascular access education alone cannot be separated. Samples were small and not powered to detect differences, and follow-up periods varied from one month to one year. Outcome measures were mostly general self-management scales; only one instrument was specific for vascular access self-management, and improvements were often reported as broad statements rather than specific behaviours. Only English-language studies from a ten-year search period were included, so relevant studies may have been missed.

The authors declared no conflicts of interest.

Do not read this as proof that a specific dialysis education programme works. Most studies embedded vascular access teaching in broader dialysis education, many had no control group or were not powered, and the review could not combine the results, so the evidence supports giving education but not choosing one format.
