Among subjects on IS, the presence of comorbidities warranting vaccination was associated with higher likelihood of H1N1 immunization (62.5% versus 35.8%; P=0.022) but not of seasonal influenza vaccination (25.0% versus 17.2%; P=0.392). Among patients without comorbidities warranting vaccination, IS was associated with a decreased likelihood of vaccination against seasonal influenza (17.2% versus 30.7%; P=0.036) but not H1N1 (35.8% versus 41.3%; P=0.46). The frequency of H1N1 vaccination was significantly higher among patients who visited a general practitioner at least once yearly (45.7% versus 20%; P=0.0027), with a similar trend for seasonal influenza vaccination (27.1% versus 12.5%; P=0.073). Among 91 patients on IS who declined vaccination, 39.6% reported fear of immediate side effects, 29.7% reported concerns about developing serious medical complications, 15.4% reported concerns about activating IBD and 15.4% were not aware that vaccination was indicated.<\/jats:p><jats:p>CONCLUSIONS: Current strategies for vaccinating IBD patients on IS are inadequate. Primary care provider education, incentive programs and regular primary care contact may improve immunization uptake.<\/jats:p>","DOI":"10.1155\/2012\/158362","type":"journal-article","created":{"date-parts":[[2016,3,15]],"date-time":"2016-03-15T03:50:08Z","timestamp":1458013808000},"page":"593-596","source":"Crossref","is-referenced-by-count":20,"title":["An Audit of Influenza Vaccination Status in Adults with Inflammatory Bowel Disease"],"prefix":"10.1155","volume":"26","author":[{"given":"Neeraj","family":"Narula","sequence":"first","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, and Farncombe Family Digestive Health Research Institute, McMaster University, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amit S","family":"Dhillon","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, and Farncombe Family Digestive Health Research Institute, McMaster University, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Usha","family":"Chauhan","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, and Farncombe Family Digestive Health Research Institute, McMaster University, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John K","family":"Marshall","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, and Farncombe Family Digestive Health Research Institute, McMaster University, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"98","container-title":["Canadian Journal of Gastroenterology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2012\/158362.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2012\/158362.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,23]],"date-time":"2016-08-23T03:36:25Z","timestamp":1471923385000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cjgh\/2012\/158362\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2012]]}},"alternative-id":["158362"],"URL":"https:\/\/doi.org\/10.1155\/2012\/158362","relation":{},"ISSN":["0835-7900"],"issn-type":[{"value":"0835-7900","type":"print"}],"subject":[],"published":{"date-parts":[[2012]]}}}
