The purpose of this study was to investigate the prevalence of preexisting atrial fibrillation (AF) in patients with MRSA-BSI during a three-year period and the impact of preexisting AF on MRSA-BSI outcomes. Methods. This was a retrospective analysis performed using the National Inpatient Sample (NIS) over a three-year period (2016, 2017, 2018) for patients with MRSA-BSI as a principal diagnosis with and without preexisting AF. The primary outcome was mortality with secondary outcomes of acute coronary syndrome, cardiac arrest, cardiogenic shock, endocarditis, respiratory failure, acute kidney injury, length of stay, hospital cost, and patient charge. A univariate and multivariable logistic regression analysis estimated clinical outcomes. Results. Preexisting AF in patients with MRSA-BSI significantly increased the primary outcome of the study, mortality (1.67% vs. 0.66%, <jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>p<\/a:mi>\n                        <a:mo>=<\/a:mo>\n                        <a:mn>0.030<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>) with an adjusted odds ratio (AOR) of 1.98 (95% CI, 1.1\u20133.7).

Conclusions. Preexisting AF is a significant risk factor for mortality in patients admitted for MRSA-BSI and increases risk for cardiac arrest, respiratory failure, and ACS. Considerations should focus on early treatment and source control, especially with AF given the mortality risk, increased hospitalization cost, and prolonged LOS.<\/jats:p>","DOI":"10.1155\/2022\/8965888","type":"journal-article","created":{"date-parts":[[2022,7,19]],"date-time":"2022-07-19T22:35:05Z","timestamp":1658270105000},"page":"1-9","source":"Crossref","is-referenced-by-count":0,"title":["Preexisting Atrial Fibrillation Associated with Higher Mortality in Patients with Methicillin-Resistant Staphylococcus aureus Bloodstream Infections: Analysis of the National Inpatient Sample"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6869-9717","authenticated-orcid":true,"given":"Timothy","family":"McCann","sequence":"first","affiliation":[{"name":"Internal Medicine Department, TriHealth-Good Samaritan Hospital, 375 Dixmyth Avenue, Cincinnati 45220, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7498-9569","authenticated-orcid":true,"given":"Michael","family":"Fatuyi","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, TriHealth-Good Samaritan Hospital, 375 Dixmyth Avenue, Cincinnati 45220, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9164-4976","authenticated-orcid":true,"given":"Neha","family":"Patel","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, TriHealth-Good Samaritan Hospital, 375 Dixmyth Avenue, Cincinnati 45220, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deepali B.","family":"Sharath","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, TriHealth-Good Samaritan Hospital, 375 Dixmyth Avenue, Cincinnati 45220, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anar S.","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, TriHealth-Good Samaritan Hospital, 3219 Clifton Avenue, Cincinnati 45220, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccc.2013.03.008"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.3947\/ic.2017.49.2.158"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1001\/jama.298.15.1763"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkr076"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-016-1563-6"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm6809e1"},{"volume-title":"Antibiotic Resistance and Patient Safety Portal Methicillin-Resistant Staphylococcus aureus","year":"2021","author":"Centers for Disease Control and Prevention","key":"7"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijid.2017.05.010"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkq373"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkt016"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.jinf.2010.09.029"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/j.jinf.2008.11.003"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-021-05763-y"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1186\/s13756-017-0193-0"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciu410"},{"volume-title":"Methicillin Resistant Staphylococcus aureus","year":"2022","author":"A.
