The incidence and prognosis of NIV failure in patients with AHF are not well characterized.\n                    <jats:bold>METHODS:<\/jats:bold>\n                    Using the National In-Patient Sample (NIS), we conducted a retrospective cohort study of subjects hospitalized with AHF between 2008 and 2014 who were treated with NIV within 24 h of hospital admission. We determined predictors of NIV failure and determined the association between NIV failure and in-hospital mortality using Cox proportional hazard models.\n                    <jats:bold>RESULTS:<\/jats:bold>\n                    Of 279,534 subjects hospitalized with AHF and treated with NIV, 4,257 (1.52%) failed NIV and required intubation. Cardiogenic shock (odds ratio 8.79, 95% CI 6.89\u201311.2) and in-hospital arrest (odds ratio 24.9, 95% CI 18.71\u201333.14) were associated with NIV failure. In-hospital mortality was 26.5% for NIV failure compared to 5.6% for those without NIV (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt; .001). After adjustment for demographics, comorbidities, cardiogenic shock, and in-hospital arrest, NIV failure was associated with nearly a 2-fold risk of in-hospital mortality (odds ratio 1.95, 95% CI 1.59\u20132.40).\n                    <jats:bold>CONCLUSIONS:<\/jats:bold>\n                    Intubation after initial NIV treatment was required in 1.5% of subjects hospitalized with AHF and treated with NIV, and was associated with high in-hospital mortality. These findings can guide future prospective interventional trials and quality improvement ventures.\n                  <\/jats:p>","DOI":"10.4187\/respcare.07661","type":"journal-article","created":{"date-parts":[[2020,5,12]],"date-time":"2020-05-12T13:12:06Z","timestamp":1589289126000},"page":"1527-1533","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Incidence, Predictors, and Outcomes of Failure of Noninvasive Ventilation in Acute Heart Failure Hospitalization"],"prefix":"10.1177","volume":"65","author":[{"given":"Thomas S","family":"Metkus","sequence":"first","affiliation":[{"name":"Division of Cardiology, Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, Maryland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P Elliott","family":"Miller","sequence":"additional","affiliation":[{"name":"Section of Cardiovascular Medicine, Yale University School of Medicine, New Haven, Connecticut."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R Scott","family":"Stephens","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, Maryland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven P","family":"Schulman","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, Maryland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaker M","family":"Eid","sequence":"additional","affiliation":[{"name":"Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, Maryland."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,5,12]]},"reference":[{"issue":"1","key":"e_1_3_2_2_2","first-page":"72","article-title":"Utilization and outcomes of early respiratory support in 6.5 million acute heart failure hospitalizations","volume":"6","author":"Metkus TS","year":"2019","unstructured":"Metkus TS, , Stephens RS, , Schulman S, , Hsu S, , Morrow DA, , Eid SM.
