ObjectivesFibromyalgia syndrome (FMS) is a chronic disorder defined by widespread muscle pain and multiple tender points. The objectives of this study were to estimate prevalence of comorbidities, healthcare resources utilization, and costs associated with FMS. MethodsA retrospective cohort study was conducted using data from the Quebec provincial health plans (RAMQ) for a random sample of patients with diagnoses of FMS and a control cohort of patients without FMS, matched for age and gender. Prevalence of comorbidities was estimated. Healthcare resources consumed by FMS and non-FMS patients were identified in terms of visits to physicians, physicians interventions, pain-related medications, nonpain-related medications, and hospitalizations. ResultsA total of 16,010 patients with 2 diagnoses of FMS were identified, and control patients were randomly selected with a ratio of 1:1. Incidence of most comorbidities was significantly higher in the FMS group and the chronic disease score (3.8 vs. 2.8; ANOVA P <0.001). The proportion of patients with at least 1 comorbidity was 87.4% in the FMS group and 60.1% in the control group (χ2P<0.001). The annual number of visits to physician and physicians interventions was 25.1 for FMS and 14.8 for non-FMS patients. The amount paid by the RAMQ was significantly higher for patients with FMS (

OBJECTIVES This study sought to estimate the economic impact of same-day home discharge compared with overnight hospitalization after transradial percutaneous coronary intervention (PCI). BACKGROUND Same-day home discharge after transradial PCI and a bolus-only abciximab regimen was found to be clinically noninferior to the abciximab standard therapy and overnight hospitalization in patients with various forms of acute coronary syndromes. METHODS In the EASY (Early Discharge After Transradial Stenting of Coronary Arteries) trial, 1,005 patients were randomized after a bolus of abciximab and uncomplicated transradial coronary stenting, either to same-day home discharge and no infusion (outpatient group) or to overnight hospitalization and 12-h abciximab infusion (overnight-stay group). We estimated post-PCI health care cost (in Canadian dollars) of trial subjects and short-term economic impact of same-day home discharge. As randomization was done after the procedure, outcomes were similar, and PCI resource use showed minimal and nonsignificant differences, a post-PCI cost-minimization analysis was conducted. Detailed per-patient information of health care resources used immediately after PCI up to 30 days was collected. RESULTS Mean post-PCI hospital stay was 8.9 h for outpatients versus 26.5 h for overnight-stay patients (p < 0.001). At 30-day follow-up, the mean cumulative medical cost per outpatient was
