Abstract

The study attempts to evaluate the hospital 30-day risk-standardized mortality rates (RSMRs) for those patients that have been discharged with acute myocardial infarction (AMI). The results indicate that there was a significant decrease in hospital mortality rate for patients with AMI.

Abstract

Registry studies have suggested improvements in door-to-balloon times, but a national assessment of the trends in door-to-balloon times is lacking. Moreover, we do not know whether improvements in door-to-balloon times were shared equally among patient and hospital groups.This analysis includes all patients reported by hospitals to the Centers for MedicareMedicaid Services for inclusion in the time to percutaneous coronary intervention (acute myocardial infarction-8) inpatient measure from January 1, 2005, through September 30, 2010. For each calendar year, we summarized the characteristics of patients reported for the measure, including the number and percentage in each group, the median time to primary percutaneous coronary intervention, and the percentage with time to primary percutaneous coronary intervention within 75 minutes and within 90 minutes. Door-to-balloon time declined from a median of 96 minutes in the year ending December 31, 2005, to a median of 64 minutes in the 3 quarters ending September 30, 2010. There were corresponding increases in the percentage of patients who had times90 minutes (44.2% to 91.4%) and75 minutes (27.3% to 70.4%). The declines in median times were greatest among groups that had the highest median times during the first period: patients75 years of age (median decline, 38 minutes), women (35 minutes), and blacks (42 minutes).National progress has been achieved in the timeliness of treatment of patients with ST-segment-elevation myocardial infarction who undergo primary percutaneous coronary intervention.

Abstract

Objective:One approach to reduce health care spending and improve coordination of care is to pay for an episode of care rather than individual services. Anchoring these episodes around an index hospitalization is sensible because hospitalizations are a leading contributor to rising healthcare costs and an index admission provides a clear time to begin the episode. Understanding which care settings are responsible for a greater proportion of expenditures can inform efforts to improve efficiencies in the care provided. Our objectives were to: 1) characterize total episode payments for two conditions and 2) examine the care settings accounting for the highest proportions of the 30-day episode of care payment.

Abstract

Background: While diabetes is a major issue for the aging U.S. population, few studies have described the recent trends in both preventive care practices and complications among the Medicare population with diabetes. Using the Medicare Quality Monitoring System (MQMS), this 2004 study describes these trends from 1992 to 2001 and how these rates vary across demographic subgroups. Methods: Outcomes include age- and gender-adjusted rates of 15 indicators associated with diabetes care from 1992 to 2001, the absolute change in rates from 1992 to 2001, and 2001 rates by demographic subgroups. The data were cross-sectional samples of Medicare beneficiaries with diabetes from 1992 to 2001 from the Medicare 5% Standard Analytic Files. Results: Use of preventive care practices rose from 1992 to 2001: 45 percentage points for HbA1c tests, 51 for lipid tests, 8 for eye exams, and 38 for self-monitoring of glucose levels (all p<0.05). Rates for short-term and some long-term complications of diabetes (e.g., lower-extremity amputations and cardiovascular conditions) fell from 1992 to 2001 (p<0.05). However, rates of other long-term complications such as nephropathy, blindness, and retinopathy rose during the period (p<0.05). Nonwhites and beneficiaries aged <65 and >85 exhibited consistently higher complication rates and lower use of preventive services. Conclusions: The Medicare program has seen some significant improvement in preventive care practices and significant declines in lower-limb amputations and cardiovascular conditions. However, rates for other long-term complications have increased, with evidence of subgroup disparities. The MQMS results provide an early warning for policymakers to focus on the diabetes care provided to some vulnerable subgroups. [Copyright &y& Elsevier]
