Do renal access coordinators make a difference? What is the evidence?

Background
Since the introduction of the renal access coordinator (RAC) role into Australia there have been only anecdotal examples of associated improvements in patient outcome and service delivery and scant published quantitative extant evidence exists.

Aim
To review the literature related to the impact of RACs on dialysis patient outcomes and associated service delivery, gauge the level of evidence available and identify gaps in the literature.

Method
A three stage Joanna Briggs Institute (JBI) systematic review process was used to collect and synthesise data. The review considered studies that explored and measured the RAC role in the adult haemodialysis context. All quantitative study designs were considered. Due to lack of homogeneity a narrative synthesis was undertaken.

Results
Five studies met the inclusion criteria for the review. All studies included multidisciplinary teams with variable emphasis on the RAC role. Four pre post intervention cohort studies measured incident and/or prevalent AVF, AVG and CVC rates in the haemodialysis population and the quality assurance report measured differences in patency rates between AVF and AVG and associated hospital length of stay. All discussed the role of central coordination as a contributor to the success of vascular access care.

Conclusion
The available reports do suggest an association between RACs and improved patient outcomes. These improved patient outcomes were apparent in an increase in incident and prevalent AVFs, and a decrease in the incidence and prevalence of CVCs. Both associations are correlated with a reduction in infection rates, length of hospital stay and healthcare costs
