Because no real\u2010world surveillance system exists to monitor their long\u2010term safety, claims data are often used for this purpose. The extent to which adverse events identified with claims data can be reasonably attributed to a specific medical device is uncertain.\n <\/jats:p>\n <\/jats:sec>\n \n Methods and Results<\/jats:title>\n \n We used deterministic matching to link the NCDR (National Cardiovascular Data Registry) Cath\n PCI<\/jats:styled-content>\n Registry to Medicare fee\u2010for\u2010service claims for patients aged \u226565\u00a0years who underwent\n PCI<\/jats:styled-content>\n with drug\u2010eluting stents (\n DESs<\/jats:styled-content>\n ) between July 1, 2009 and December 31, 2013. We identified subsequent\n PCI<\/jats:styled-content>\n s within 1\u00a0year of the index procedure in Medicare claims as potential safety events. We linked these subsequent\n PCI<\/jats:styled-content>\n s back to the\n NCDR<\/jats:styled-content>\n Cath\n PCI<\/jats:styled-content>\n Registry to ascertain how often the revascularization could be reasonably attributed to the same coronary artery as the index\n PCI<\/jats:styled-content>\n (ie, target vessel revascularization). Of 415\u00a0306\n DES<\/jats:styled-content>\n placements in 368\u00a0194 patients, 33\u00a0174 repeat\n PCI<\/jats:styled-content>\n s were identified in Medicare claims within 1\u00a0year. Of these, 28\u00a0632 (86.3%) could be linked back to the\n NCDR<\/jats:styled-content>\n Cath\n PCI<\/jats:styled-content>\n Registry; 16\u00a0942 (51.1% of repeat\n PCI<\/jats:styled-content>\n s) were target vessel revascularizations. Of these, 8544 (50.4%) were within a previously placed\n DES<\/jats:styled-content>\n : 7652 for in\u2010stent restenosis and 1341 for stent thrombosis. Of 16\u00a0176 patients with a claim for acute myocardial infarction in the follow\u2010up period, 4446 (27.5%) were attributed to the same coronary artery in which the\n DES<\/jats:styled-content>\n was implanted during the index\n PCI<\/jats:styled-content>\n (ie, target vessel myocardial infarction). Of 24\u00a0288 patients whose death was identified in claims data, 278 (1.1%) were attributed to the same coronary artery in which the\n DES<\/jats:styled-content>\n was implanted during the index\n PCI<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n Most repeat\n PCI<\/jats:styled-content>\n s following\n DES<\/jats:styled-content>\n stent implantation identified in longitudinal claims data could be linked to real\u2010world registry data, but only half could be reasonably attributed to the same coronary artery as the index procedure. Attribution among those with acute myocardial infarction or who died was even less frequent. Safety signals identified using claims data alone will require more in\u2010depth examination to accurately assess stent safety.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1161\/jaha.119.013606","type":"journal-article","created":{"date-parts":[[2020,2,16]],"date-time":"2020-02-16T10:00:27Z","timestamp":1581847227000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":16,"title":["Attribution of Adverse Events Following Coronary Stent Placement Identified Using Administrative Claims Data"],"prefix":"10.1161","volume":"9","author":[{"given":"Sanket S.","family":"Dhruva","sequence":"first","affiliation":[{"name":"University of California, San Francisco, School of Medicine and San Francisco Veterans Affairs Healthcare System San Francisco CA"},{"name":"National Clinician Scholars Program Yale School of Medicine New Haven CT"},{"name":"Center for Outcomes Research and Evaluation Yale\u2013New Haven Hospital New Haven CT"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig S.","family":"Parzynski","sequence":"additional","affiliation":[{"name":"Center for Outcomes Research and Evaluation Yale\u2013New Haven Hospital New Haven CT"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ginger M.","family":"Gamble","sequence":"additional","affiliation":[{"name":"Center for Outcomes Research and Evaluation Yale\u2013New Haven Hospital New Haven CT"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeptha P.","family":"Curtis","sequence":"additional","affiliation":[{"name":"Center for Outcomes Research and Evaluation Yale\u2013New Haven Hospital New Haven CT"},{"name":"Section\u00a0of Cardiovascular Medicine Department of Medicine, and National Clinician Scholars Program Yale School of Medicine New Haven CT"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nihar R.","family":"Desai","sequence":"additional","affiliation":[{"name":"Center for Outcomes Research and Evaluation Yale\u2013New Haven Hospital New Haven CT"},{"name":"Section\u00a0of Cardiovascular Medicine Department of Medicine, and National Clinician Scholars Program Yale School of Medicine New Haven CT"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert W.","family":"Yeh","sequence":"additional","affiliation":[{"name":"Richard A. and Susan F.
