We evaluated an approach using secondary bacterial culture (SBC) to contend with residual risk of bacterial contamination.<\/jats:p><\/jats:sec><jats:sec><jats:title>STUDY DESIGN AND METHODS<\/jats:title><jats:p>Phased implementation of SBC was initiated in October 2016 for platelets (all apheresis collected) received at our institution from the blood donor center (Day 3 post collection). Platelet products were sampled aseptically (5 mL inoculated into an aerobic bottle [BacT\/ALERT BPA, BioMerieux, Inc.]) by the blood bank staff upon receipt, using a sterile connection device and sampling kit. The platelet sample was inoculated into an aerobic blood culture bottle and incubated at 35\u00b0C for 3 days. The cost of SBC was calculated on the basis of consumables and labor costs at time of implementation.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>In the 13 months following implementation (October 6, 2016, to November 30, 2017), 23,044\/24,653 (93.47%) platelet products underwent SBC. A total of eight positive cultures were detected (incidence 1 in 2881 platelet products), seven of which were positive within 24 hours of SBC. Coagulase negative <jats:italic>Staphyloccus<\/jats:italic> spp. were identified in four cases. Five of the eight cases were probable true positive (repeat reactive) and interdicted (cost per averted case was US$77,935). The remaining three cases were indeterminate. No septic transfusion reactions were reported during the observation period.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>We demonstrate the feasibility of SBC of apheresis platelets to mitigate bacterial risk. SBC is lower cost than alternative measures (e.g., pathogen reduction and point\u2010of\u2010release testing) and can be integrated into workflow at hospital transfusion services.<\/jats:p><\/jats:sec>","DOI":"10.1111\/trf.14618","type":"journal-article","created":{"date-parts":[[2018,4,2]],"date-time":"2018-04-02T04:49:04Z","timestamp":1522644544000},"page":"1647-1653","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Implementation of secondary bacterial culture testing of platelets to mitigate residual risk of septic transfusion reactions"],"prefix":"10.1111","volume":"58","author":[{"given":"Evan M.","family":"Bloch","sequence":"first","affiliation":[{"name":"Department of Pathology, Transfusion Medicine Division Johns Hopkins University Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christi E.","family":"Marshall","sequence":"additional","affiliation":[{"name":"Department of Pathology, Transfusion Medicine Division Johns Hopkins University Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joan S.","family":"Boyd","sequence":"additional","affiliation":[{"name":"Department of Pathology, Transfusion Medicine Division Johns Hopkins University Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Shifflett","sequence":"additional","affiliation":[{"name":"Department of Pathology, Transfusion Medicine Division Johns Hopkins University Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaron A.R.","family":"Tobian","sequence":"additional","affiliation":[{"name":"Department of Pathology, Transfusion Medicine Division Johns Hopkins University Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric A.","family":"Gehrie","sequence":"additional","affiliation":[{"name":"Department of Pathology, Transfusion Medicine Division Johns Hopkins University Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul M.","family":"Ness","sequence":"additional","affiliation":[{"name":"Department of Pathology, Transfusion Medicine Division Johns Hopkins University Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,4]]},"reference":[{"key":"e_1_2_7_2_1","volume-title":"Fatalities reported to FDA following blood collection and transfusion annual summary for FY2015","author":"FDA","year":"2015"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.2001.41121493.x"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tmrv.2003.10.002"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0042-9007.2004.00404.x"},{"key":"e_1_2_7_6_1","first-page":"9","article-title":"Platelet concentrates: reducing the risk of transfusion\u2010transmitted bacterial infections","volume":"2","author":"Korte DM","year":"2014","journal-title":"Int J Clin Transf Med"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1537-2995.2007.01132.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.14202"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1086\/529143"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2015-07-655944"},{"key":"e_1_2_7_11_1","unstructured":"FDA\u2010CBER.Bacterial risk control strategies for blood collection establishments and transfusion services to enhance the safety and availability of platelets for transfusion.2016[cited 2018 Mar 16].
