To test the feasibility and acceptability of a newly developed model of neonatal nurse-controlled analgesia to manage pain in the post-operative infant.
The study utilised a single-centre two-arm parallel, unblinded randomised controlled external pilot trial design.
The pilot trial was conducted in a surgical neonatal tertiary intensive care unit in Brisbane, Australia. Eligible infants were randomised to receive either post-operative pain management care via a model of neonatal nurse-controlled analgesia or standard care. Feasibility and acceptability were the primary outcomes. Seven feasibility outcomes were assessed by a traffic light system to delineate progression to a larger trial. Acceptability and clinical utility of the model of care by staff were assessed by feedback from an anonymous questionnaire that was administered at the completion of the trial period. Secondary outcomes included parental attitudes and perceptions of post-operative pain management to help establish primary outcomes for a larger randomised controlled trial.
Overall staff found the formalised model beneficial for managing post-operative pain but found the complexity of the model and ability to titrate analgesia based only on documented pain scores barriers requiring further consideration. Three of the seven feasibility outcomes failed to reach ‘greenlight’ targets to progress to a larger trial with adherence to the model, and the proportion of eligible infants not recruited was allocated a ‘redlight’. Secondary outcomes were comparable and support future study.
This pilot feasibility study has shown that a model of neonatal nurse-controlled analgesia can be safely implemented and utilised in the post-operative care of the surgical neonate. Further exploration of the barriers to model adherence and recruitment is warranted before a future larger trial is undertaken.
Though not all primary outcomes reached an acceptable range for further progression, this pilot feasibility study provided invaluable learning and has provided direction for future research into the provision of a family integrated and responsive model of analgesia.

The incidence of anal carcinoma is increasing, with the current gold standard treatment being chemoradiotherapy. There is currently a wide range in the radiotherapy dose used internationally which may lead to overtreatment of early-stage disease and potential undertreatment of locally advanced disease.
PLATO is an integrated umbrella trial protocol which consists of three trials focused on assessing risk-adapted use of adjuvant low-dose chemoradiotherapy in anal margin tumours (ACT3), reduced-dose chemoradiotherapy in early anal carcinoma (ACT4) and dose-escalated chemoradiotherapy in locally advanced anal carcinoma (ACT5), given with standard concurrent chemotherapy.
The primary endpoints of PLATO are locoregional failure (LRF)-free rate for ACT3 and ACT4 and LRF-free survival for ACT5. Secondary objectives include acute and late toxicities, colostomy-free survival and patient-reported outcome measures. ACT3 will recruit 90 participants: participants with removed anal tumours with margins ≤1 mm will receive lower dose chemoradiotherapy, while participants with anal tumours with margins >1 mm will be observed. ACT4 will recruit 162 participants, randomised on a 1:2 basis to receive either standard-dose intensity modulated radiotherapy (IMRT) in combination with chemotherapy or reduced-dose IMRT in combination with chemotherapy. ACT5 will recruit 459 participants, randomised on a 1:1:1 basis to receive either standard-dose IMRT in combination with chemotherapy, or one of two increased-dose experimental arms of IMRT with synchronous integrated boost in combination with chemotherapy.
This study has been approved by Yorkshire & The Humber – Bradford Leeds Research Ethics Committee (ref: 16/YH/0157, IRAS: 204585), July 2016. Results will be disseminated via national and international conferences, peer-reviewed journal articles and social media. A plain English report will be shared with the study participants, patients’ organisations and media.
