Rheumatoid Arthritis Does Not Negatively Impact Outcomes of Patients Admitted for Atrial Fibrillation

Abstract

This study aimed to compare the outcomes of patients primarily admitted for atrial fibrillation (AF) with and without a secondary diagnosis of rheumatoid arthritis (RA). The primary outcome of interest was inpatient mortality. Hospital length of stay (LOS), total hospital charges, and odds of undergoing ablation and pharmacologic cardioversion were the secondary outcomes of interest.

Psoriasis Is Associated With an Increased Risk of Hospitalization for Systemic Lupus Erythematosus: Analysis of the National Inpatient Sample Database

“…Hence, we waived institutional review board approval. This section is similar to prior NIS papers [14][15][16][17][18][19].…”

“…The NIS is under the jurisdiction of the Agency for Healthcare Research and Quality [14]. NIS is the largest inpatient national database in the US [15,16]. Discharges are weighted to maintain national representation [17].…”

Protein-Energy Malnutrition Increases Mortality in Patients Hospitalized With Bacterial Pneumonia: A Retrospective Nationwide Database Analysis

“…These were obtained from prior related studies reviewed and included variables from the validated pneumonia severity index [16]. A univariate screen was done to further confirm these factors affected outcomes with variables having a p-value less than 0.2 included in the multivariate analysis [17][18][19][20]. The threshold for statistical significance was 0.05.…”

Obesity Impacts Mortality and Rate of Revascularizations Among Patients With Acute Myocardial Infarction: An Analysis of the National Inpatient Sample

“…It approximates a 20% stratified sample of discharges from US community hospitals, excluding rehabilitation and long-term acute care hospitals [ 17 , 18 ]. This dataset is weighted to obtain national estimates [ 19 , 20 ]. Both the 2016 and 2017 database are coded using the International Classification of Diseases, Tenth Revision, Clinical Modification/Procedure Coding System (ICD-10-CM/PCS) [ 21 , 22 ].…”
