The annual rates of hospitalization for the primary diagnosis of RA decreased from 76.54 admissions per 1 million in 2000 to 29.96 per 1 million in 2014 (<jats:italic>P<\/jats:italic> trend &lt; 0.0001). The hospital mortality rate declined from 0.70% to 0.41% (<jats:italic>P<\/jats:italic> trend &lt; 0.0001) in this group. With a primary or nonprimary diagnosis of RA, the mortality rate ranged between 1.95 and 2.87 (<jats:italic>P<\/jats:italic> trend 0.08). For a nonprimary diagnosis of RA, we noted that the proportion of hospitalizations with a diagnosis of myocardial infarction (6.4% in 2000 to 4.6% in 2014; <jats:italic>P<\/jats:italic> &lt; 0.001) significantly decreased, but the absolute number of hospitalizations significantly increased. In contrast, the proportion and the absolute number of hospitalizations with any diagnosis of sepsis, congestive heart failure, lung disease, and urinary tract infection increased significantly. We also noted a significant increase in the actual rate and proportions for hospitalizations for hip and knee arthroplasty. Among in\u2010hospital deaths when RA was a nonprimary diagnosis, the most common primary diagnosis was pneumonia (12.5 %) in 2000, whereas sepsis accounted for the most deaths in 2014 (31.4%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We observed that hospitalization rates and in\u2010hospital mortality rates in patients with RA have changed significantly over the past 15 years.<\/jats:p><\/jats:sec>","DOI":"10.1002\/acr2.11200","type":"journal-article","created":{"date-parts":[[2020,11,20]],"date-time":"2020-11-20T16:27:09Z","timestamp":1605889629000},"page":"715-724","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Trends in Hospitalization Rates, Major Causes of Hospitalization, and In\u2010Hospital Mortality in Rheumatoid Arthritis in the United States From 2000 to 2014"],"prefix":"10.1002","volume":"2","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4863-5585","authenticated-orcid":false,"given":"Priyanka","family":"Iyer","sequence":"first","affiliation":[{"name":"University of California at Irvine Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yubo","family":"Gao","sequence":"additional","affiliation":[{"name":"Iowa City Veteran\u2019s Affairs Medical Center, and University of Iowa Iowa City Iowa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth H.","family":"Field","sequence":"additional","affiliation":[{"name":"Iowa City Veteran\u2019s Affairs Medical Center, and University of Iowa Iowa City Iowa"},{"name":"University of Iowa Iowa City"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8907-8976","authenticated-orcid":false,"given":"Jeffrey R.","family":"Curtis","sequence":"additional","affiliation":[{"name":"University of Alabama at Birmingham"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles F.","family":"Lynch","sequence":"additional","affiliation":[{"name":"University of Iowa Iowa City"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary","family":"Vaughan\u2010Sarrazin","sequence":"additional","affiliation":[{"name":"Iowa City Veteran\u2019s Affairs Medical Center, and University of Iowa Iowa City Iowa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1460-1117","authenticated-orcid":false,"given":"Namrata","family":"Singh","sequence":"additional","affiliation":[{"name":"University of Washington Seattle"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,11,20]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2018.13103"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.23177"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mayocp.2014.12.009"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/BOR.0000000000000389"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s41927-018-0014-y"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00296-016-3638-5"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.10419"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.509"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.22553"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.22642"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.22296"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.23328"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.3899\/jrheum.170001"},{"key":"e_1_2_8_15_1","article-title":"Rheumatoid arthritis vs osteoarthritis: comparison of demographics and trends of joint replacement data from the nationwide inpatient sample","volume":"47","author":"Kurdi AJ","year":"2018","journal-title":"Am J Orthop (Belle Mead NJ)"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.21984"},{"key":"e_1_2_8_17_1","first-page":"143","article-title":"The healthcare cost and utilization project: an overview","volume":"5","author":"Steiner C","year":"2002","journal-title":"Eff Clin Pract"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.berh.2004.05.002"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00296-015-3351-9"},{"key":"e_1_2_8_20_1","unstructured":"Healthcare Cost and Utilization Project.Nationwide inpatient sample redesign: final report.2014.
