The design included a 6-week run-in time. Following this there were alternating 1-week intervention and control periods. The intervention group received a communication strategy describing the potential harms of unnecessary imaging for low back pain, shown on a 55\u201d LCD screen positioned in the ED waiting room. The communication strategy was designed by a creative innovation agency and included five digital posters and a patient leaflet. The control group received standard messaging for the waiting room at the time, shown on the same 55\u201d LCD screen, and access to the patient leaflet. The primary outcome was the number and proportion of people presenting to ED with low back pain who received at least one lumbar imaging test, measured using routinely collected ED data. Secondary patient-reported outcomes (patient satisfaction and awareness of campaign messages) were collected from a sample of people presenting for any condition who responded to a text-message-based survey.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>For the imaging outcome, 337 people presenting to ED with low back pain were included over a 4-month period (intervention n\u2009=\u200999; control n\u2009=\u2009238). All had available data on lumbar imaging. Use of lumbar imaging was 25% in those exposed to the communication strategy [95% confidence interval (CI)\u2009=\u200918% to 35%] compared with 29% in those exposed to the standard waiting room messaging [95% CI\u2009=\u200923% to 35%; odds ratio (OR)\u2009=\u20090.83, 95% CI\u2009=\u20090.49 to 1.41]. For the patient-reported outcomes, 349 patients presenting to ED for any condition responded to the survey (intervention n\u2009=\u2009170; control n\u2009=\u2009179; response rate\u2009=\u200933%). There was uncertain evidence that the intervention increased awareness of the communication strategy leaflet (OR\u2009=\u20092.00, 95% CI\u2009=\u20090.90 to 4.47). Other measures did not suggest between-group differences in patient satisfaction or awareness of the campaign messages.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>A communication strategy displayed in the ED waiting room may slightly reduce the proportion of patients with low back pain who receive lumbar imaging, although there is uncertainty due to imprecision. The campaign did not appear to increase awareness of campaign messages or affect patient satisfaction in a sample of patients presenting to the ED for any reason. Larger studies should investigate whether simple, low-cost waiting room communication strategies can raise awareness of unnecessary healthcare and influence health-care quality.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Trial registration<\/jats:title>\n                  <jats:p>ACTRN12620000300976, 05\/03\/2020<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/intqhc\/mzab129","type":"journal-article","created":{"date-parts":[[2021,9,8]],"date-time":"2021-09-08T11:23:15Z","timestamp":1631100195000},"source":"Crossref","is-referenced-by-count":8,"title":["Effect of a waiting room communication strategy on imaging rates and awareness of public health messages for low back pain"],"prefix":"10.1093","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0919-8813","authenticated-orcid":false,"given":"Sweekriti","family":"Sharma","sequence":"first","affiliation":[{"name":"Institute for Musculoskeletal Health, The University of Sydney and Sydney Local Health District, New South Wales 2050, Australia"},{"name":"School of Public Health, The University of Sydney, New South Wales 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrian C","family":"Traeger","sequence":"additional","affiliation":[{"name":"Institute for Musculoskeletal Health, The University of Sydney and Sydney Local Health District, New South Wales 2050, Australia"},{"name":"School of Public Health, The University of Sydney, New South Wales 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elise","family":"Tcharkhedian","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, Liverpool Hospital, Sydney, NSW 2170, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul M","family":"Middleton","sequence":"additional","affiliation":[{"name":"South Western Emergency Research Institute, Liverpool Hospital, Liverpool, NSW 2170, Australia"},{"name":"Discipline of Emergency Medicine, University of Sydney, Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6611-8229","authenticated-orcid":false,"given":"Louise","family":"Cullen","sequence":"additional","affiliation":[{"name":"Emergency and Trauma Center, Royal Brisbane and Women\u2019s Hospital, University of Queensland, Brisbane, QLD 4029, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chris G","family":"Maher","sequence":"additional","affiliation":[{"name":"Institute for Musculoskeletal Health, The University of Sydney and Sydney Local Health District, New South Wales 2050, Australia"},{"name":"School of Public Health, The University of Sydney, New South Wales 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,10,8]]},"reference":[{"key":"2022030513192697800_R1","doi-asserted-by":"crossref","first-page":"478","DOI":"10.7326\/0003-4819-147-7-200710020-00006","article-title":"Diagnosis and treatment of low back pain: a joint clinical practice guideline from the American College of Physicians and the American Pain Society","volume":"147","author":"Chou","year":"2007","journal-title":"Ann Intern Med"},{"key":"2022030513192697800_R2","doi-asserted-by":"crossref","first-page":"642","DOI":"10.1136\/bjsports-2018-100087","article-title":"How common is imaging for low back pain in primary and emergency care?
