Thematic analysis identified that most patients were not aware of their condition until medical check-up; physician referral was the main reason for trial participation, and patients had high expectations regardless of previous acupuncture experiences. Patients tended to depend on their physicians' opinions because they felt helpless of their condition. No one questioned their assigned treatment groups and generally believed acupuncture treatment was different for cardiovascular diseases. A few patients expressed disappointment in the strict and rigid protocols, in which most practitioners refrained from explaining their acupuncture procedures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>For cardiovascular patients their physician's advice was one of the biggest reasons for enrolling in the acupuncture trial therefore relying on standard recruitment methods may not be effective. Fortunately both real and sham acupuncture groups in our sample were receiving treatment as intended, but in the future, designing a more pragmatic trial (better reflecting clinical settings, expanding the inclusion criteria and using more treatment points) will allow researchers to better explore the comprehensive effects of acupuncture. The findings of this study will allow researchers to improve the currently ongoing ACU-AF trial and to further help interpretation of main trial outcomes once the trial is completed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Trial registration number:<\/jats:title><jats:p><jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"https:\/\/clinicaltrials.gov\/ct2\/show\/NCT02110537?term=acupuncture+atrial+fibrillation&amp;rank=1\" ext-link-type=\"uri\">NCT02110537.<\/jats:ext-link><\/jats:p><\/jats:sec>","DOI":"10.1136\/bmjopen-2016-013180","type":"journal-article","created":{"date-parts":[[2017,2,4]],"date-time":"2017-02-04T01:25:34Z","timestamp":1486171534000},"page":"e013180","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":10,"title":["Close look at the experiences of patients enrolled in a clinical trial of acupuncture treatment for atrial fibrillation in Korea: a qualitative study nested within a randomised controlled trial"],"prefix":"10.1136","volume":"7","author":[{"given":"Seung Min Kathy","family":"Lee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3300-5556","authenticated-orcid":false,"given":"Jungtae","family":"Leem","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun Hyeong","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kang Hyun","family":"Yoon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong Shin","family":"Woo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung Myung","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin-Bae","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weon","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanghoon","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2017,2,3]]},"reference":[{"key":"2024051611144378000_7.2.e013180.1","doi-asserted-by":"publisher","DOI":"10.2147\/CLEP.S47385"},{"key":"2024051611144378000_7.2.e013180.2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehm358"},{"key":"2024051611144378000_7.2.e013180.3","doi-asserted-by":"crossref","first-page":"e71","DOI":"10.4070\/kcj.2016.46.4.515","article-title":"Incidence and risk factors for atrial fibrillation in Korea: the National Health Insurance Service Database (2002\u20132010)","volume":"46","author":"Son","year":"2016","journal-title":"Korean Circ J"},{"key":"2024051611144378000_7.2.e013180.4","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.22.8.983"},{"key":"2024051611144378000_7.2.e013180.5","doi-asserted-by":"crossref","first-page":"5","DOI":"10.1016\/j.amjmed.2005.10.057","article-title":"Quality of life in patients with atrial fibrillation: a systematic review","volume":"119","author":"Thrall","year":"2006","journal-title":"Am J Med"},{"key":"2024051611144378000_7.2.e013180.6","unstructured":"United Nations, Department of Economic and Social Affairs, Population Division (2015).
