The study sample was stratified into 4 groups (White, Black, Hispanic, and other races). Baseline characteristics, procedural complications, and key in-hospital outcomes were then assessed. We also analyzed the independent association of race\/ethnicity with key in-hospital outcomes including major complications, prolonged hospital stay, and increased hospitalization cost.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              A total of 34\u2009960 Watchman recipients were included in the final analysis. Black and Hispanic patients had higher prevalence of heart failure, hypertension, obesity, and renal failure when compared with White patients. The crude rate of overall procedural complications was also higher in Blacks, Hispanics, and patients of other race when compared with White patients (15.2%, 12.4%, and 14.1% versus 9.9%;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.01). After multivariable adjustment, compared with White patients, Blacks, Hispanics, and patients of other race experienced a higher likelihood of a major complication from the procedure (adjusted odds ratio, 1.223 [95% CI, 0.986\u20131.517], 1.296 [95% CI, 1.075\u20131.561], and 1.924 [95% CI, 1.569\u20132.360], respectively) and prolonged length of stay &gt;1 day (adjusted odds ratio, 1.631 [95% CI, 1.431\u20131.859], 1.239 [95% CI, 1.110\u20131.383], and 1.619 [95% CI, 1.403\u20131.869], respectively).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>Non-White patients undergoing Watchman implantation had higher prevalence of key comorbidities and also experienced increased Watchman-related adverse events including procedural complications and prolonged length of stay, even after adjustment for potential confounders.
