Devising and delivering the UK's first nurse-led cardiac catheter laboratory radial access programme

Traditionally, radial artery access (RAA) has been an exclusively 'physician-delivered' service, but with adequate training, nurse-led arterial cannulation can become widely adopted. In this clinical audit, senior nursing practitioners with at least two years of catheter lab experience, were offered RAA training. In phase 1 of training, two nurses were initially familiarised with a well-structured training protocol. Each of the two nurses carried out the first 50 RAA procedures under supervision on elective patients. In phase 2, candidates independently performed 100 procedures. The success and complication rates of these procedures were evaluated prior to their sign-off as competent. The procedural efficacy of nurses was compared with medical registrars of the department to assess the measures of patient satisfaction and time elapsed prior to the insertion of sheath. During the first 100 directly observed RAA procedures, nurse 1 and nurse 2 achieved success rates of 84% (42/50 procedures) and 86% (43/50 procedures), respectively. During the second phase, nurse 1 achieved a success rate of 82% (82/100 procedures), whereas nurse 2 achieved a success rate of 97% (97/100 procedures). Overall, a success rate of 88% was achieved in the first 300 patients. No significant complications were noted. In contrast to medical registrars, nurse-led cannulation was associated with a greater extent of patient satisfaction, reduced pain intensity (p<0.001), and decreased patient-on-table to sheath insertion intervals (p<0.001). During embedding of the programme, the two nursing practitioners trained additional nurses. Of the five nurses that subsequently entered into training, two have successfully completed both training phases while a further three have completed phase 1. To date, an overall success rate of 91.1% (1,307/1,435 procedures) has been documented. In conclusion, a nurse-led RAA program is feasible, with satisfactory success rates, no significant complications, and improved rates of patient satisfaction.
