ObjectivesThere are significant pressures on resident medical rotas on intensive care. We have evaluated the safety and feasibility of nurse practitioners (NPs) delivering first-line care on an intensive care unit with all doctors becoming non-resident. Previously, resident doctors on a 1:8 full-shift rota supported by NPs delivered first-line care to patients after cardiac surgery. Subsequently, junior doctors changed to a 1:5 non-resident rota and NPs onto a 1:7 full-shift rota provided first-line care.MethodsA single centre before-and-after service evaluation on cardiac intensive care.Key Measures For Improvementmortality rates, surgical trainee attendance in theatre and cost before and after the change. After-hour calls by NPs to doctors and subsequent actions were also audited after the change.ResultsThe overall mortality rates in the 12 months before the change were 2.8 and 2.2% in the 12 months after (P = 0.43). The median [range] logistic EuroSCORE was 5.3 [0.9-84] before and 5.0 [0.9-85] after the change (P = 0.16). After accounting for the risk profile, the odds ratio for death after the change relative to before was 0.83, 95% confidence interval 0.41-1.69. Before the change, a surgical trainee attended theatre 467 of 702 (68%) cases. This increased to 539 of 677 (80%) cases after the change (P < 0.001). The annual cost of staffing the junior doctor and NP programme before the change was £933 344 and £764 691 after. In the year after the change, 192 after-hour calls were made to doctors. In 57% of cases telephone advice sufficed and doctors attended in 43%.ConclusionsWith adequate training and appropriate support, resident NPs can provide a safe, sustainable alternative to traditional staffing models of cardiac intensive care. Training opportunities for junior surgeons increased and costs were reduced.
