Abstract

To determine trends and impact on outcomes of atrial fibrillation (AF) in patients with pre-existing major depressive disorder(MDD). While post-AF MDD has been extensively studied, contemporary studies including temporal trends on impact of pre-AF MDD on AF and post-AF outcomes are lacking. We used Nationwide Inpatient Sample (NIS) from Healthcare Cost and Utilization Project (HCUP) from 2002 to 2012. We identified AF and MDD as primary and secondary diagnosis respectively using validated International Classification of Diseases, 9th Revision, and Clinical Modification (ICD9CM) codes, and used Cochrane-Armitage trend test and multivariate regression to generate adjusted odds ratios (aOR). We analyzed total of 3,887,827 AF hospital admissions from 2002 to 2012 of which 6.78% had MDD. Proportion of hospitalizations with MDD increased from 4.93% to 14.19% (P-trend<0.001). Utilization of atrial cardioversion was lower in patients with MDD (34.37% vs. 40.52%, P<0.001). In-hospital mortality was significantly lower in patients with MDD (aOR0.749; 95% CI 0.664–0.846; P<0.001) but discharge to specialty care was higher (aOR 1.695; 95%CI 1.650–1.741; P<0.001). In addition, median length of hospitalization (2.5 vs. 2.13 days; P<0.001) and median cost of hospitalization (28,246 vs. 22,663; P<0.001) was higher in hospitalizations with MDD. Our study displayed an increasing proportion of patients with MDD admitted due to AF in the last decade with lower mortality but higher morbidity post-AF. In addition, there was significantly less utilization of atrial cardioversion in this population along with higher median length and cost of hospitalization. There is a need to explore the reasons behind this disparity in outcomes and atrial cardioversion utilization in order to improve post-AF outcomes in this vulnerable population.
