A 25\u2010question electronic survey on couch overrides and tolerances was sent to full members of the American Association of Physicists in Medicine (AAPM). The first part of the survey asked participants if table overrides were allowed at their institution, who was allowed to perform these overrides, and if imaging was required with overrides. The second part of the survey asked individuals to provide table tolerance data for the following treatment sites: brain\/head and neck (H&amp;N), lung, breast, abdomen\/pelvis and prostate. Each site was further divided into IMRT\/VMAT and 3D conformal techniques. Spaces for free\u2010text were provided, allowing respondents to enter any table tolerance data they were unable to specify under the treatment sites listed. A total of 361 individuals responded, of which approximately half participated in the couch tolerances portion of the survey. Overall, 86% of respondents\u2019 institutions allow couch tolerance overrides at treatment. Therapists were the most common staff members permitted to perform overrides, followed by physicists, dosimetrists, and physicians, respectively. Of the institutions allowing overrides, 34% reported overriding daily. More than half of the centers document the override and\/or require a setup image to radiographically verify the treatment site. With respect to table tolerances, SRS\/SBRT table tolerances were the tightest, while clinical setup table tolerances were the largest. There were minimal statistically significant differences between IMRT\/VMAT and 3D conformal table tolerances. Our results demonstrated that table overrides are relatively common in radiotherapy despite being a potential safety concern. Institutions should review their override policy and table tolerance values in light of the practices of other institutions. Careful attention to these matters is crucial in ensuring the safe and accurate delivery of radiotherapy.<\/jats:p><jats:p>PACS number(s): 87.55.N\u2010, 87.55.Qr, 87.55.T\u2010<\/jats:p>","DOI":"10.1120\/jacmp.v17i6.6261","type":"journal-article","created":{"date-parts":[[2017,2,28]],"date-time":"2017-02-28T00:58:12Z","timestamp":1488243492000},"page":"405-420","source":"Crossref","is-referenced-by-count":7,"title":["A survey on table tolerances and couch overrides in radiotherapy"],"prefix":"10.1002","volume":"17","author":[{"given":"Bonnie","family":"Chinsky","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology Loyola University Medical Center  Maywood IL USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rakesh","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology Loyola University Medical Center  Maywood IL USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joshua","family":"Panfil","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology Loyola University Medical Center  Maywood IL USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Murat","family":"Surucu","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology Loyola University Medical Center  Maywood IL USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John C.","family":"Roeske","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology Loyola University Medical Center  Maywood IL USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,11,8]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"A1","article-title":"Radiation offers new cures, and ways to do harm","volume":"23","author":"Bogdanich W","year":"2010","journal-title":"NewYork Times."},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2012.10.015"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2012.04.036"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2013.02.003"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1200\/JOP.2011.000237"},{"key":"e_1_2_8_7_1","volume-title":"The checklist manifesto: how to get things right","author":"Gawande A","year":"2010"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacr.2011.07.014"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/jjco\/hyn112"},{"key":"e_1_2_8_10_1","volume-title":"Safety is no accident: a framework for quality radiation oncology and care","author":"Zietman AL","year":"2012"},{"key":"e_1_2_8_11_1","volume-title":"ASTRO and AAPM announce launch of RO\u2010ILS: Radiation Oncology Incident Learning System","author":"Kirkwood M","year":"2014"},{"issue":"3","key":"e_1_2_8_12_1","first-page":"87","article-title":"Errors in radiation therapy","volume":"6","author":"Commonwealth of Pennsylvania Patient Safety Authority","year":"2009","journal-title":"Pennsylvania Patient Safety Advisory."},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1120\/jacmp.v10i4.2864"}],"container-title":["Journal of Applied Clinical Medical Physics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1120%2Fjacmp.v17i6.6261","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1120%2Fjacmp.v17i6.6261","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/aapm.onlinelibrary.wiley.com\/doi\/pdf\/10.1120\/jacmp.v17i6.6261","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,7]],"date-time":"2023-10-07T01:13:06Z","timestamp":1696641186000},"score":1,"resource":{"primary":{"URL":"https:\/\/aapm.onlinelibrary.wiley.com\/doi\/10.1120\/jacmp.v17i6.6261"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,11]]},"references-count":12,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2016,11]]}},"alternative-id":["10.1120\/jacmp.v17i6.6261"],"URL":"https:\/\/doi.org\/10.1120\/jacmp.v17i6.6261","archive":["Portico"],"relation":{},"ISSN":["1526-9914","1526-9914"],"issn-type":[{"value":"1526-9914","type":"print"},{"value":"1526-9914","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,11]]}}}
