Summary

The Acute Care Surgery (ACS) paradigm unites emergency general surgery, trauma management and critical care into a single, dedicated service line available 24 hours a day. Initially conceived to address delays and fragmentation in urgent surgical care, ACS models typically feature attending surgeons relieved of elective duties, continuous in-house resident coverage and reserved operating‐room capacity. Implementation has been highly variable across regions, with some centres embedding critical care within the ACS unit while others maintain separate intensive care structures. Evaluations of ACS services consistently demonstrate reductions in time to theatre, fewer after-hours procedures, improved surgeon work–life balance and stable elective schedules. Outcome measures extend beyond timeliness to encompass length of stay, complication rates and patient throughput. Concurrently, the formal recognition of ACS as a subspecialty has spurred the development of consensus guidelines, quality metrics and tiered regional networks. These advances underscore the global relevance of ACS models in optimising resource use, standardising emergency surgical care and enhancing both patient and provider experience.

About these summaries

This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
