We searched all ED encounters potentially due to anaphylaxis after vaccination, between 1 January 2010 and 31 December 2018, using ICD\u201010\u2010CM codes T80.5, T80.6, T88.1, T88.6, and T78.2. Health records of potential cases were examined to determine if they met the Brighton Collaboration (BC) criteria for anaphylaxis. We calculated the PPV to evaluate the accuracy of the selected ICD\u201010\u2010CM codes in predicting anaphylaxis due to vaccination.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 69 health records identified and reviewed, 29 (42.2%) met the criteria for anaphylaxis regardless of the cause, and 24.6% (17\/69) of records were confirmed as anaphylaxis triggered by vaccination (low positive predictive value). However, of the 23 records identified using ICD\u201010\u2010CM code T80.5, 22 were classified as anaphylaxis cases regardless of the cause, and 12 were anaphylaxis due to vaccination cases giving PPV of 95.7% and 52.2%, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Given that there is no specific ICD\u201010\u2010CM code for anaphylaxis due to vaccination, ICD\u201010\u2010CM code T80.5 may be suitable to monitor anaphylaxis due to vaccination in the ED setting. The current study was conducted at a single centre and needs to be confirmed by future multicentre studies.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pds.4877","type":"journal-article","created":{"date-parts":[[2019,8,23]],"date-time":"2019-08-23T08:33:00Z","timestamp":1566549180000},"page":"1353-1360","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Positive predictive value of ICD\u201010 codes to detect anaphylaxis due to vaccination: A validation study"],"prefix":"10.1002","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0010-9845","authenticated-orcid":false,"given":"Yonatan Moges","family":"Mesfin","sequence":"first","affiliation":[{"name":"Monash Centre for Health Research and Implementation, School of Public Health and Preventive Medicine Monash University  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Allen C.","family":"Cheng","sequence":"additional","affiliation":[{"name":"Infection Prevention and Healthcare Epidemiology Unit Alfred Health  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aimy H.L.","family":"Tran","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Victoria Australia"},{"name":"The Ritchie Centre Hudson Institute of Medical Research  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jim","family":"Buttery","sequence":"additional","affiliation":[{"name":"Monash Centre for Health Research and Implementation, School of Public Health and Preventive Medicine Monash University  Melbourne Victoria Australia"},{"name":"Monash Children Hospital Monash Health  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,8,23]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1359-6446(04)03234-9"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1538-5442(01)70025-9"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.2008.143081"},{"issue":"3","key":"e_1_2_11_5_1","first-page":"E377","article-title":"Surveillance of adverse events following immunisation in Australia annual report, 2014","volume":"40","author":"Dey A","year":"2016","journal-title":"Commun Dis Intell Q Rep"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjgh-2018-001065"},{"key":"e_1_2_11_7_1","doi-asserted-by":"crossref","unstructured":"MesfinYM ChengAC LawrieJock et al.Use of routinely collected electronic health care data for post\u2010licensure vaccine safety signal detection: a systematic review Unpublished.2019.","DOI":"10.1136\/bmjgh-2018-001065"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2014.02.044"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1136\/archdischild-2017-312941"},{"key":"e_1_2_11_10_1","unstructured":"World Health Organization.ICD\u201010: International statistical classification of diseases and related health problems: World Health Organization.2004."},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.112.4.815"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2007.02.064"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaci.2015.07.048"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/pds.3505"},{"key":"e_1_2_11_15_1","unstructured":"Monash Health Innovate Reconciliation Action Plan (2016\u20102018).
