Abstract
Introduction Core surgical training programmes are associated with a high risk of burnout. This study aimed to assess the influence of a novel enhanced stress-resilience training (ESRT) course delivered at the start of core surgical training in a single UK statutory education body. Method All newly appointed core surgical trainees (CSTs) were invited to participate in a 5-week ESRT course teaching mindfulness-based exercises to develop tools to deal with stress at work and burnout. The primary aim was to assess the feasibility of this course; secondary outcomes were to assess degree of burnout measured using Maslach Burnout Inventory (MBI) scoring. Results Of 43 boot camp attendees, 38 trainees completed questionnaires, with 24 choosing to participate in ESRT (63.2 per cent; male 13, female 11, median age 28 years). Qualitative data reflected challenges delivering ESRT because of arduous and inflexible clinical on-call rotas, time pressures related to academic curriculum demands and the concurrent COVID-19 pandemic (10 of 24 drop-out). Despite these challenges, 22 (91.7 per cent) considered the course valuable and there was unanimous support for programme development. Of the 14 trainees who completed the ESRT course, nine (64.3 per cent) continued to use the techniques in daily clinical work. Burnout was identified in 23 trainees (60.5 per cent) with no evident difference in baseline MBI scores between participants (median 4 (range 0–11) versus 5 (1–11), P = 0.770). High stress states were significantly less likely, and mindfulness significantly higher in the intervention group (P < 0.010); MBI scores were comparable before and after ESRT in the intervention cohort (P = 0.630, median 4 (range 0–11) versus 4 (1–10)). Discussion Despite arduous emergency COVID rotas ESRT was feasible and, combined with protected time for trainees to engage, deserves further research to determine medium-term efficacy.

Abstract
INTRODUCTION Gastrointestinal recovery describes the restoration of normal bowel function in patients with bowel disease. This may be prolonged in two common clinical settings: postoperative ileus and small bowel obstruction. Improving gastrointestinal recovery is a research priority but researchers are limited by variation in outcome reporting across clinical studies. This protocol describes the development of core outcome sets for gastrointestinal recovery in the contexts of postoperative ileus and small bowel obstruction. METHOD An international Steering Group consisting of patient and clinician representatives has been established. As overlap between clinical contexts is anticipated, both outcome sets will be co-developed and may be combined to form a common output with disease-specific domains. The development process will comprise three phases, including definition of outcomes relevant to postoperative ileus and small bowel obstruction from systematic literature reviews and nominal-group stakeholder discussions; online-facilitated Delphi surveys via international networks; and a consensus meeting to ratify the final output. A nested study will explore if the development of overlapping outcome sets can be rationalized. DISSEMINATION AND IMPLEMENTATION The final output will be registered with the Core Outcome Measures in Effectiveness Trials initiative. A multi-faceted, quality improvement campaign for the reporting of gastrointestinal recovery in clinical studies will be launched, targeting international professional and patient groups, charitable organizations and editorial committees. Success will be explored via an updated systematic review of outcomes 5 years after registration of the core outcome set.

Abstract
OBJECTIVES The variable-flow flow driver (FD; EME) and continuous-flow bubble (Fisher-Paykel) continuous positive airway pressure (CPAP) systems are widely used. As these differ in cost and technical requirements, determining comparative efficacy is important particularly where resources are limited. DESIGN We performed a randomised, controlled, equivalence trial of CPAP systems. We specified the margin of equivalence as 2 days. We analysed binary variables by logistical regression adjusted for gestation, and log transformed continuous variables by multiple linear regression adjusted for gestation, sex and antenatal steroids. SETTING A neonatal unit with no blood gas analyser or surfactant availability and limited X-ray and laboratory facilities PATIENTS Neonates <37 weeks of gestation. INTERVENTIONS We provided CPAP at delivery followed by randomisation to FD or bubble (B). OUTCOMES Primary outcome included total days receiving CPAP; secondary outcomes included days receiving CPAP, supplemental oxygen, ventilation, death, pneumothorax and nasal excoriation. RESULTS We randomised 125 infants (B 66, FD 59). Differences in infant outcomes on B and FD were not statistically significant. The median (range) for CPAP days for survivors was B 0.8 (0.04 to 17.5), FD 0.5 (0.04 to 5.3). B:FD (95% CI) ratios were CPAP days 1.3 (0.9 to 2.1), CPAP plus supplementary oxygen days 1.2 (0.7 to 1.9). B:FD (95% CI) ORs were death 2.3 (0.2 to 28), ventilation 2.1 (0.5 to 9), nasal excoriation 1.2 (0.2 to 8) and pneumothorax 2.4 (0.2 to 26). CONCLUSIONS In a resource-limited setting we found B CPAP equivalent to FD CPAP in the total number of days receiving CPAP within a margin of 2 days. TRIAL REGISTRATION NUMBER ISRCTN22578364.
