Abstract 15131: National Rates and Trends of Tobacco and Substance Use Disorders Among Atrial Fibrillation Hospitalizations in the United States


 Introduction:
 Atrial Fibrillation (AF) has been associated with various behavioral risk factors such as tobacco, alcohol, and/or substance abuse.
 
 
 Hypothesis:
 The main objective is to describe the national trends and burden of tobacco and substance abuse in AF hospitalizations.
 
 
 Methods:
 The National Inpatient Sample database from 2007 to 2015 was utilized and the hospitalizations with AF were identified using the international classification of disease, Ninth Revision, Clinical Modification (ICD-9-CM) code 427.31 in the primary diagnosis column. They were stratified into without abuse, tobacco use disorder (TUD), substance use disorder (SUD), alcohol use disorder (AUD), and drug use disorder (DUD). We used the Jonckheere-Terpstra trend test to analyze the trend in this study.
 
 
 Results:
 Out of 3,631,507 AF hospitalizations, 852,110 (23.46%) had TUD, 1851,170 (5.1%) had SUD, 155,681 (4.29%) had AUD and 42,667 (1.17%) had DUD. The trends of all increased substantially during the study period
 (Figure)
 . The prevalence of TUD, SUD, AUD, and DUD was substantially increased across all age groups, races, and gender during the study period. Female sex was associated with lower odds TUD (0.57 (0.56-0.57), P-value <0.001), SUD (0.27 (0.26-0.27), P-value <0.001), AUD (0.22 (0.22-0.22), P-value <0.001), and DUD (0.51 (0.5-0.52), P-value <0.001). Among AF hospitalizations, the black race was associated with higher odds of SUD (1.12 (1.1-1.14), P-value <0.001), and DUD(1.42 (1.38-1.47), P-value <0.001). The younger age group (18-35 years), male, Medicare/Medicaid as primary insurance, and lower socioeconomic status were associated with increased risk of both TUD and SUDs.
 
 
 Conclusions:
 Tobacco and substance use disorder among hospitalized AF patients in the US mainly affects males, younger individuals, white more than black, and those of lower socioeconomic status which demands the development of preventive strategies to address multilevel influences.
