Introduction: Antiarrhythmic drugs (AADs) are commonly used for the treatment of newly diagnosed symptomatic atrial fibrillation (AF), however initial AAD choice, duration of therapy, rates of discontinuation, and factors associated with a durable response to therapy are poorly understood. This study assesses the initial choice and duration of antiarrhythmic drug therapy in the first 2 years after diagnosis of AF in a younger, commercially insured population.
Methods: A large nationally representative sample of patients age 20-64 was studied using the IBM MarketScan Database.
Background: Radiofrequency catheter ablation is an effective treatment to alleviate symptoms and reduce recurrent implantable cardioverter-defibrillator (ICD/CRT-D) shocks in patients with ventricular tachycardia (VT).
Objective: To assess the characteristics and outcomes (complications, inpatient readmissions) of commercially insured patients in the USA undergoing ablation for ischaemic or non-ischaemic VT.
Methods: Patients aged 18-64 years with a primary diagnosis of VT who underwent ablation between 2006 and 2015 were identified using the IBM MarketScan Commercial Database.
Objectives: This study identified factors associated with risk for cardiac perforation in the setting of atrial fibrillation (AF) ablation in contemporary clinical practice.
Background: Cardiac perforation is an uncommon but potentially fatal complication of AF ablation. An improved understanding of factors associated with cardiac perforation could facilitate improvements in procedural safety.
Introduction: This study evaluated trends related to breast reconstruction and the factors associated with reconstruction.
Methods: Women with breast cancer aged 19 to 64 years who underwent a mastectomy procedure between July 1, 2011, and September 30, 2014, were identified from the MarketScan Commercial Claims and Encounters Database. The first date of surgical procedure during this period was defined as the index date.
Introduction: Video-assisted thoracic surgery (VATS) lung resections are complex procedures with a critical role played by endoscopic staplers in the transection of vessels, bronchi, and lung tissue. This retrospective, observational study compared hospital resource use, costs, and complications of VATS lobectomy procedures for whom powered versus manual endoscopic surgical staplers were used.
Methods: Patients ≥ 18 years of age undergoing elective VATS lobectomy during an inpatient admission from January 1, 2012 to September 30, 2016 were identified from the Premier Healthcare Database (first admission = index admission).
Objectives: To determine hospital resource utilization, associated costs and the risk of complications during hospitalization for four types of surgical resections and to estimate the incremental burden among patients with cancer compared to those without cancer.
Methods: Patients (≥18 years old) were identified from the Premier Research Database of US hospitals if they had any of the following types of elective surgical resections between 1/2008 and 12/2014: lung lobectomy, lower anterior resection of the rectum (LAR), liver wedge resection, or total hysterectomy. Cancer status was determined based on ICD-9-CM diagnosis codes.
Aims: To compare economic and clinical outcomes between patients undergoing laparoscopic Roux-en-Y gastric bypass (LRY) or laparoscopic sleeve gastrectomy (LSG) with use of powered vs manual endoscopic surgical staplers.
Materials And Methods: Patients (aged ≥21 years) who underwent LRY or LSG during a hospital admission (January 1, 2012-September 30, 2015) were identified from the Premier Perspective Hospital Database. Use of powered vs manual staplers was identified from hospital administrative billing records.
