We aimed to enhance the emergency general surgical service in our high-volume centre in order to reduce four-hour target breaches, to expedite senior decision making and to avoid unnecessary admissions. The aggregation of marginal gains theory was applied. A dual consultant on-call system was established by the incremental employment of five emergency general surgeons with a specialist interest in colorectal or oesophagogastric surgery. A surgical ambulatory care unit, which combines consultant-led clinical review with dedicated next-day radiology slots, and a dedicated working week half-day gastrointestinal urgent theatre session were instituted to facilitate ambulatory care pathways. The presence of two consultant surgeons being on call during weekday working hours decreased the four-hour target breaches and allowed consultant presence in the surgical ambulatory care clinic and the gastrointestinal urgent theatre list. Of 1371 surgical ambulatory care clinic appointments within 30 months, 1135 (82.7%) avoided a hospital admission, corresponding to savings of £309,752 . The coordinated functioning of the surgical ambulatory care clinic and the gastrointestinal urgent theatre list resulted in statistically significantly reduced hospital stays for patients operated for abscess drainage (gastrointestinal urgent theatre median 11 hours (interquartile range 3, 38) compared with emergency median 31 hours (interquartile range 24, 53), < 0.001) or diagnostic laparoscopy/appendicectomy (gastrointestinal urgent theatre median 52 hours (interquartile range 41, 71) compared with emergency median 61 hours (interquartile range 43, 99), = 0.005). Overnight surgery was reduced with only surgery that was absolutely necessary occurring out of hours. The expansion of the 'traditional' on-call surgical team, the establishment of the surgical ambulatory care clinic and the gastrointestinal urgent theatre list led to marginal gains with a reduction in unnecessary inpatient stays, expedited decision making and improved financial efficiency.
