Input: We identified two eligible studies, both comparing nurse-led POA with POA led by non-specialist doctors, with a total of 2469 participants. One study was randomized and the other quasi-randomized. Blinding of staff and participants to allocation was not possible. In both studies, all participants were additionally assessed by a specialist doctor (anaesthetist in training), who acted as the reference standard. In neither study did participants proceed from assessment by nurse or junior doctor to surgery. Neither study reported on cancellations of surgery, gain in participant information or knowledge or perioperative complications. Reported outcomes focused on the accuracy of the assessment. One study undertook qualitative assessment of participant satisfaction with the two forms of POA in a small number of non-randomly selected participants (42 participant interviews), and both groups of participants expressed high levels of satisfaction with the care received. This study also examined economic modelling of costs of the POA as performed by the nurse and by the non-specialist doctor based on the completeness of the assessment as noted in the study and found no difference in cost. Currently, no evidence is available from RCTs to allow assessment of whether nurse-led POA leads to an increase or a decrease in cancellations or perioperative complications or in knowledge or satisfaction among surgical participants. One study, which was set in the UK, reported equivalent costs from economic models. Nurse-led POA is now widespread, and it is not clear whether future RCTs of this POA strategy are feasible. A diagnostic test accuracy review may provide useful information.
Output:

In February 2013, we searched medical databases to look for controlled trials of participants who had undergone surgery and had been randomly assigned to nurse- or doctor-led preoperative assessment (POA). We found two trials, one randomized and one quasi-randomized. Both studies were conducted in the UK and compared POA performed by the nurse with POA performed by the non-specialist doctor. One studied 1874 adult participants who were undergoing elective surgery, and the other studied 595 children who were undergoing day surgery. Neither study reported on cancellations of surgery, gain in participant information or knowledge or perioperative complications. Reported outcomes focused on the accuracy of the assessment. As there is currently no evidence from trials concerning the impact of nurse-led POA on patient outcomes, we are unable to make any recommendations for practice on the basis of this review.
