There were no significant changes to ED durations during nurse strikes (-1.7%, 95% CI -1.5% to 4.7%). Changes in emergency inpatient occupancy explained a proportion of the change in average ED durations (resident doctor 10.4%, consultants 53.3%, combined doctors 5.4% and paramedics 14.3%). The impact of strikes on ED attendance volumes was mixed. The net effect of these changes explained 1.5%, 16.8% and 28.8% of the change in average ED durations observed during residents, combined doctor and paramedic strikes, respectively. During the residents\u2019 strikes, patients were more likely to receive treatments in ED (adjusted incident risk ratio 1.013, 95% CI 1.008\u20131.018), but less likely to be admitted (adjusted odds ratio 0.963, 95% CI 0.946\u20130.980). Efforts to meet the 4-h target intensified during the resident, consultant and combined doctors strike, but reduced during the nurse and paramedic strikes. This explained 2.7% and 17.1% of the changes in average ED durations observed during the resident and consultant strikes, respectively. There were substantial reductions in many forms of planned hospital care during the resident, consultant and combined doctor strikes, but these did not contribute to the observed reductions in ED durations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Industrial action \u2013 particularly by resident and consultant doctors \u2013 was associated with shorter ED stays, partly mediated by greater emergency bed availability, lower demand and intensified throughput efforts. However, much of the reduction during resident strikes remained unexplained, suggesting unmeasured operational or behavioural adaptations. Substantial reductions in planned care did not significantly affect ED performance.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/01410768261461989","type":"journal-article","created":{"date-parts":[[2026,8,10]],"date-time":"2026-08-10T06:55:13Z","timestamp":1786344913000},"page":"190-204","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Industrial action and emergency department attendances in England, 2022\u20132024: a retrospective multicentre causal mediation analysis"],"prefix":"10.1177","volume":"119","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3332-0866","authenticated-orcid":false,"given":"Steven","family":"Wyatt","sequence":"first","affiliation":[{"name":"The Strategy Unit, Birmingham, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0987-4268","authenticated-orcid":false,"given":"Mohammed A.","family":"Mohammed","sequence":"additional","affiliation":[{"name":"The Strategy Unit, Birmingham, England, UK"},{"name":"University of Bradford, Bradford, England, UK"},{"name":"Cardiff Business School, University of Cardiff, Cardiff, Wales, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Clarke","sequence":"additional","affiliation":[{"name":"The Health Foundation, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4939-0575","authenticated-orcid":false,"given":"Marta","family":"Garcia-Fi\u00f1ana","sequence":"additional","affiliation":[{"name":"Institute of Population Health, University of Liverpool, Liverpool, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3392-1650","authenticated-orcid":false,"given":"Iain","family":"Buchan","sequence":"additional","affiliation":[{"name":"University of Liverpool, Liverpool, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,9]]},"reference":[{"key":"e_1_3_4_2_2","unstructured":"Peterson F.
