Background: Data regarding the temporal trends, outcomes, and predictors of in-hospital mortality after pericardiocentesis are limited. Methods: The National Inpatient Sample database was used to extract hospitalizations of patients who underwent pericardiocentesis from January 2007 to September 2015. We examined the rates of in-hospital mortality, its predictors, and the temporal trends of pericardiocentesis utilization in the United States during the study period. We also examined trends and outcomes of pericardiocentesis associated with different cardiovascular procedures. Results: A total of 96,377 hospitalizations with pericardiocentesis were examined. The number of pericardiocentesis procedures performed trended up significantly between 2007 and 2015 (p trend <.001), and this increase was observed predominantly in patients with unstable conditions. In-hospital mortality after pericardiocentesis decreased over time (14.6% in 2007 vs. 12.0% in 2015, p trend <.001), but remained higher than that after surgical pericardial intervention (13.1 vs. 8.9%, p value <.0001), predominantly attributable to a higher patient risk profile. Rates of in-hospital mortality were not statistically different between the procedural cohort and the nonprocedural cohort, 13.5 versus 13.0%, p value =.051. After multivariable adjustment, structural heart interventions (odds ratio [OR] 2.86; 95% confidence interval [CI] 2.35–3.49), bacterial and/or infective endocarditis (OR 2.09; 95% CI 1.72–2.54) and active neoplasms (OR 1.72; 95% CI 1.6–1.85) were independently associated with increased in-hospital mortality in pericardiocentesis patients. Conclusion: In this nationwide analysis, the number of pericardiocentesis procedures increased significantly over time. Structural interventions, endocarditis, and active neoplasms were associated with increased in-hospital mortality after pericardiocentesis.
