Objectives: Exacerbations account for the greatest proportion of costs associated with chronic obstructive pulmonary disease (COPD). Here we aimed to evaluate, from the US payer perspective, the costs associated with moderate and severe COPD exacerbation events for patients treated with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) compared with FF/VI or UMEC/VI.
Study Design: This post hoc, within-trial economic analysis used data derived from the InforMing the PAthway of COPD Treatment (IMPACT) study (NCT02164513).
Background: Patients with chronic obstructive pulmonary disease (COPD) often have multiple underlying comorbidities, which may lead to increased health care resource utilization (HCRU) and costs.
Objective: To describe the comorbidity profiles of COPD patients and examine the associations between the presence of comorbidities and HCRU or health care costs.
Methods: A retrospective cohort study utilizing data from a large US national health plan with a predominantly Medicare population was conducted.
Background: Arteriovenous fistula (AVF) use is reported to differ among racial and gender groups. We sought to identify risk factors associated with incident AVF and whether racial and gender differences in AVF use persist after controlling for these factors.
Methods: We evaluated 28,712 incident adult hemodialysis patients (age ≥ 18) from five ESRD networks starting dialysis between June 1, 2005 and May 31, 2006.
Background: Patients receiving long-term hemodialysis have a yearly mortality rate of 15% to 20%.
Objective: To determine whether attaining clinical performance measures for hemodialysis care is associated with favorable 12-month mortality and hospitalization rates.
Design: Cohort study.
