Importance: Patient safety is a US national priority, yet lacks a comprehensive assessment of progress over the past decade.Objective: To determine the change in the rate of adverse events in hospitalized patients.Design, Setting, and Participants: This serial cross-sectional study used data from the Medicare Patient Safety Monitoring System from 2010 to 2019 to assess in-hospital adverse events in patients. The study included 244 542 adult patients hospitalized in 3156 US acute care hospitals across 4 condition groups from 2010 through 2019: acute myocardial infarction (17%), heart failure (17%), pneumonia (21%), and major surgical procedures (22%); and patients hospitalized from 2012 through 2019 for all other conditions (22%).Exposures: Adults aged 18 years or older hospitalized during each included calendar year.Main Outcomes and Measures: Information on adverse events (abstracted from medical records) included 21 measures across 4 adverse event domains: adverse drug events, hospital-acquired infections, adverse events after a procedure, and general adverse events (hospital-acquired pressure ulcers and falls). The outcomes were the total change over time for the observed and risk-adjusted adverse event rates in the subpopulations.Results: The study sample included 190 286 hospital discharges combined in the 4 condition-based groups of acute myocardial infarction, heart failure, pneumonia, and major surgical procedures (mean age, 68.0 [SD, 15.9] years; 52.6% were female) and 54 256 hospital discharges for the group including all other conditions (mean age, 57.7 [SD, 20.7] years; 59.8% were female) from 3156 acute care hospitals across the US. From 2010 to 2019, the total change was from 218 to 139 adverse events per 1000 discharges for acute myocardial infarction, from 168 to 116 adverse events per 1000 discharges for heart failure, from 195 to 119 adverse events per 1000 discharges for pneumonia, and from 204 to 130 adverse events per 1000 discharges for major surgical procedures. From 2012 to 2019, the rate of adverse events for all other conditions remained unchanged at 70 adverse events per 1000 discharges. After adjustment for patient and hospital characteristics, the annual change represented by relative risk in all adverse events per 1000 discharges was 0.94 (95% CI, 0.93-0.94) for acute myocardial infarction, 0.95 (95% CI, 0.94-0.96) for heart failure, 0.94 (95% CI, 0.93-0.95) for pneumonia, 0.93 (95% CI, 0.92-0.94) for major surgical procedures, and 0.97 (95% CI, 0.96-0.99) for all other conditions. The risk-adjusted adverse event rates declined significantly in all patient groups for adverse drug events, hospital-acquired infections, and general adverse events. For patients in the major surgical procedures group, the risk-adjusted rates of events after a procedure declined significantly.Conclusions and Relevance: In the US between 2010 and 2019, there was a significant decrease in the rates of adverse events abstracted from medical records for patients admitted for acute myocardial infarction, heart failure, pneumonia, and major surgical procedures and there was a significant decrease in the adjusted rates of adverse events between 2012 and 2019 for all other conditions. Further research is needed to understand the extent to which these trends represent a change in patient safety. [ABSTRACT FROM AUTHOR]

Importance: The elimination of racial and ethnic differences in health status and health care access is a US goal, but it is unclear whether the country has made progress over the last 2 decades.Objective: To determine 20-year trends in the racial and ethnic differences in self-reported measures of health status and health care access and affordability among adults in the US.Design, Setting, and Participants: Serial cross-sectional study of National Health Interview Survey data, 1999-2018, that included 596 355 adults.Exposures: Self-reported race, ethnicity, and income level.Main Outcomes and Measures: Rates and racial and ethnic differences in self-reported health status and health care access and affordability.Results: The study included 596 355 adults (mean [SE] age, 46.2 [0.07] years, 51.8% [SE, 0.10] women), of whom 4.7% were Asian, 11.8% were Black, 13.8% were Latino/Hispanic, and 69.7% were White. The estimated percentages of people with low income were 28.2%, 46.1%, 51.5%, and 23.9% among Asian, Black, Latino/Hispanic, and White individuals, respectively. Black individuals with low income had the highest estimated prevalence of poor or fair health status (29.1% [95% CI, 26.5%-31.7%] in 1999 and 24.9% [95% CI, 21.8%-28.3%] in 2018), while White individuals with middle and high income had the lowest (6.4% [95% CI, 5.9%-6.8%] in 1999 and 6.3% [95% CI, 5.8%-6.7%] in 2018). Black individuals had a significantly higher estimated prevalence of poor or fair health status than White individuals in 1999, regardless of income strata (P < .001 for the overall and low-income groups; P = .03 for middle and high-income group). From 1999 to 2018, racial and ethnic gaps in poor or fair health status did not change significantly, with or without income stratification, except for a significant decrease in the difference between White and Black individuals with low income (-6.7 percentage points [95% CI, -11.3 to -2.0]; P = .005); the difference in 2018 was no longer statistically significant (P = .13). Black and White individuals had the highest levels of self-reported functional limitations, which increased significantly among all groups over time. There were significant reductions in the racial and ethnic differences in some self-reported measures of health care access, but not affordability, with and without income stratification.Conclusions and Relevance: In a serial cross-sectional survey study of US adults from 1999 to 2018, racial and ethnic differences in self-reported health status, access, and affordability improved in some subgroups, but largely persisted.

Importance: Current guidelines recommend ticagrelor as the preferred P2Y12 platelet inhibitor for patients with acute coronary syndrome (ACS), primarily based on a single large randomized clinical trial. The benefits and risks associated with ticagrelor vs clopidogrel in routine practice merits attention.Objective: To determine the association of ticagrelor vs clopidogrel with ischemic and hemorrhagic events in patients undergoing percutaneous coronary intervention (PCI) for ACS in clinical practice.Design, Setting, and Participants: A retrospective cohort study of patients with ACS who underwent PCI and received ticagrelor or clopidogrel was conducted using 2 United States electronic health record-based databases and 1 nationwide South Korean database from November 2011 to March 2019. Patients were matched using a large-scale propensity score algorithm, and the date of final follow-up was March 2019.Exposures: Ticagrelor vs clopidogrel.Main Outcomes and Measures: The primary end point was net adverse clinical events (NACE) at 12 months, composed of ischemic events (recurrent myocardial infarction, revascularization, or ischemic stroke) and hemorrhagic events (hemorrhagic stroke or gastrointestinal bleeding). Secondary outcomes included NACE or mortality, all-cause mortality, ischemic events, hemorrhagic events, individual components of the primary outcome, and dyspnea at 12 months. The database-level hazard ratios (HRs) were pooled to calculate summary HRs by random-effects meta-analysis.Results: After propensity score matching among 31 290 propensity-matched pairs (median age group, 60-64 years; 29.3% women), 95.5% of patients took aspirin together with ticagrelor or clopidogrel. The 1-year risk of NACE was not significantly different between ticagrelor and clopidogrel (15.1% [3484/23 116 person-years] vs 14.6% [3290/22 587 person-years]; summary HR, 1.05 [95% CI, 1.00-1.10]; P = .06). There was also no significant difference in the risk of all-cause mortality (2.0% for ticagrelor vs 2.1% for clopidogrel; summary HR, 0.97 [95% CI, 0.81-1.16]; P = .74) or ischemic events (13.5% for ticagrelor vs 13.4% for clopidogrel; summary HR, 1.03 [95% CI, 0.98-1.08]; P = .32). The risks of hemorrhagic events (2.1% for ticagrelor vs 1.6% for clopidogrel; summary HR, 1.35 [95% CI, 1.13-1.61]; P = .001) and dyspnea (27.3% for ticagrelor vs 22.6% for clopidogrel; summary HR, 1.21 [95% CI, 1.17-1.26]; P < .001) were significantly higher in the ticagrelor group.Conclusions and Relevance: Among patients with ACS who underwent PCI in routine clinical practice, ticagrelor, compared with clopidogrel, was not associated with significant difference in the risk of NACE at 12 months. Because the possibility of unmeasured confounders cannot be excluded, further research is needed to determine whether ticagrelor is more effective than clopidogrel in this setting.

Importance: Publicly available data sets hold much potential, but their unique design may require specific analytic approaches.Objective: To determine adherence to appropriate research practices for a frequently used large public database, the National Inpatient Sample (NIS) of the Agency for Healthcare Research and Quality (AHRQ).Design, Setting, and Participants: In this observational study of the 1082 studies published using the NIS from January 2015 through December 2016, a representative sample of 120 studies was systematically evaluated for adherence to practices required by AHRQ for the design and conduct of research using the NIS.Exposures: None.Main Outcomes and Measures: All studies were evaluated on 7 required research practices based on AHRQ's recommendations and compiled under 3 domains: (1) data interpretation (interpreting data as hospitalization records rather than unique patients); (2) research design (avoiding use in performing state-, hospital-, and physician-level assessments where inappropriate; not using nonspecific administrative secondary diagnosis codes to study in-hospital events); and (3) data analysis (accounting for complex survey design of the NIS and changes in data structure over time).Results: Of 120 published studies, 85% (n = 102) did not adhere to 1 or more required practices and 62% (n = 74) did not adhere to 2 or more required practices. An estimated 925 (95% CI, 852-998) NIS publications did not adhere to 1 or more required practices and 696 (95% CI, 596-796) NIS publications did not adhere to 2 or more required practices. A total of 79 sampled studies (68.3% [95% CI, 59.3%-77.3%]) among the 1082 NIS studies screened for eligibility did not account for the effects of sampling error, clustering, and stratification; 62 (54.4% [95% CI, 44.7%-64.0%]) extrapolated nonspecific secondary diagnoses to infer in-hospital events; 45 (40.4% [95% CI, 30.9%-50.0%]) miscategorized hospitalizations as individual patients; 10 (7.1% [95% CI, 2.1%-12.1%]) performed state-level analyses; and 3 (2.9% [95% CI, 0.0%-6.2%]) reported physician-level volume estimates. Of 27 studies (weighted; 218 studies [95% CI, 134-303]) spanning periods of major changes in the data structure of the NIS, 21 (79.7% [95% CI, 62.5%-97.0%]) did not account for the changes. Among the 24 studies published in journals with an impact factor of 10 or greater, 16 (67%) did not adhere to 1 or more practices, and 9 (38%) did not adhere to 2 or more practices.Conclusions and Relevance: In this study of 120 recent publications that used data from the NIS, the majority did not adhere to required practices. Further research is needed to identify strategies to improve the quality of research using the NIS and assess whether there are similar problems with use of other publicly available data sets.

Importance: The Affordable Care Act has led to US national reductions in hospital 30-day readmission rates for heart failure (HF), acute myocardial infarction (AMI), and pneumonia. Whether readmission reductions have had the unintended consequence of increasing mortality after hospitalization is unknown.Objective: To examine the correlation of paired trends in hospital 30-day readmission rates and hospital 30-day mortality rates after discharge.Design, Setting, and Participants: Retrospective study of Medicare fee-for-service beneficiaries aged 65 years or older hospitalized with HF, AMI, or pneumonia from January 1, 2008, through December 31, 2014.Exposure: Thirty-day risk-adjusted readmission rate (RARR).Main Outcomes and Measures: Thirty-day RARRs and 30-day risk-adjusted mortality rates (RAMRs) after discharge were calculated for each condition in each month at each hospital in 2008 through 2014. Monthly trends in each hospital's 30-day RARRs and 30-day RAMRs after discharge were examined for each condition. The weighted Pearson correlation coefficient was calculated for hospitals' paired monthly trends in 30-day RARRs and 30-day RAMRs after discharge for each condition.Results: In 2008 through 2014, 2 962 554 hospitalizations for HF, 1 229 939 for AMI, and 2 544 530 for pneumonia were identified at 5016, 4772, and 5057 hospitals, respectively. In January 2008, mean hospital 30-day RARRs and 30-day RAMRs after discharge were 24.6% and 8.4% for HF, 19.3% and 7.6% for AMI, and 18.3% and 8.5% for pneumonia. Hospital 30-day RARRs declined in the aggregate across hospitals from 2008 through 2014; monthly changes in RARRs were -0.053% (95% CI, -0.055% to -0.051%) for HF, -0.044% (95% CI, -0.047% to -0.041%) for AMI, and -0.033% (95% CI, -0.035% to -0.031%) for pneumonia. In contrast, monthly aggregate changes across hospitals in hospital 30-day RAMRs after discharge varied by condition: HF, 0.008% (95% CI, 0.007% to 0.010%); AMI, -0.003% (95% CI, -0.005% to -0.001%); and pneumonia, 0.001% (95% CI, -0.001% to 0.003%). However, correlation coefficients in hospitals' paired monthly changes in 30-day RARRs and 30-day RAMRs after discharge were weakly positive: HF, 0.066 (95% CI, 0.036 to 0.096); AMI, 0.067 (95% CI, 0.027 to 0.106); and pneumonia, 0.108 (95% CI, 0.079 to 0.137). Findings were similar in secondary analyses, including with alternate definitions of hospital mortality.Conclusions and Relevance: Among Medicare fee-for-service beneficiaries hospitalized for heart failure, acute myocardial infarction, or pneumonia, reductions in hospital 30-day readmission rates were weakly but significantly correlated with reductions in hospital 30-day mortality rates after discharge. These findings do not support increasing postdischarge mortality related to reducing hospital readmissions. [ABSTRACT FROM AUTHOR]

Importance: Postmarket safety events of novel pharmaceuticals and biologics occur when new safety risks are identified after initial regulatory approval of these therapeutics. These safety events can change how novel therapeutics are used in clinical practice and inform patient and clinician decision making.Objectives: To characterize the frequency of postmarket safety events among novel therapeutics approved by the US Food and Drug Administration (FDA), and to examine whether any novel therapeutic characteristics known at the time of FDA approval were associated with increased risk.Design and Setting: Cohort study of all novel therapeutics approved by the FDA between January 1, 2001, and December 31, 2010, followed up through February 28, 2017.Exposures: Novel therapeutic characteristics known at the time of FDA approval, including drug class, therapeutic area, priority review, accelerated approval, orphan status, near-regulatory deadline approval, and regulatory review time.Main Outcomes and Measures: A composite of (1) withdrawals due to safety concerns, (2) FDA issuance of incremental boxed warnings added in the postmarket period, and (3) FDA issuance of safety communications.Results: From 2001 through 2010, the FDA approved 222 novel therapeutics (183 pharmaceuticals and 39 biologics). There were 123 new postmarket safety events (3 withdrawals, 61 boxed warnings, and 59 safety communications) during a median follow-up period of 11.7 years (interquartile range [IQR], 8.7-13.8 years), affecting 71 (32.0%) of the novel therapeutics. The median time from approval to first postmarket safety event was 4.2 years (IQR, 2.5-6.0 years), and the proportion of novel therapeutics affected by a postmarket safety event at 10 years was 30.8% (95% CI, 25.1%-37.5%). In multivariable analysis, postmarket safety events were statistically significantly more frequent among biologics (incidence rate ratio [IRR] = 1.93; 95% CI, 1.06-3.52; P = .03), therapeutics indicated for the treatment of psychiatric disease (IRR = 3.78; 95% CI, 1.77-8.06; P < .001), those receiving accelerated approval (IRR = 2.20; 95% CI, 1.15-4.21; P = .02), and those with near-regulatory deadline approval (IRR = 1.90; 95% CI, 1.19-3.05; P = .008); events were statistically significantly less frequent among those with regulatory review times less than 200 days (IRR = 0.46; 95% CI, 0.24-0.87; P = .02).Conclusions and Relevance: Among 222 novel therapeutics approved by the FDA from 2001 through 2010, 32% were affected by a postmarket safety event. Biologics, psychiatric therapeutics, and accelerated and near-regulatory deadline approval were statistically significantly associated with higher rates of events, highlighting the need for continuous monitoring of the safety of novel therapeutics throughout their life cycle.

Importance: Readmission rates declined after announcement of the Hospital Readmission Reduction Program (HRRP), which penalizes hospitals for excess readmissions for acute myocardial infarction (AMI), heart failure (HF), and pneumonia.Objective: To compare trends in readmission rates for target and nontarget conditions, stratified by hospital penalty status.Design, Setting, and Participants: Retrospective cohort study of Medicare fee-for-service beneficiaries older than 64 years discharged between January 1, 2008, and June 30, 2015, from 2214 penalty hospitals and 1283 nonpenalty hospitals. Difference-interrupted time-series models were used to compare trends in readmission rates by condition and penalty status.Exposure: Hospital penalty status or target condition under the HRRP.Main Outcomes and Measures: Thirty-day risk adjusted, all-cause unplanned readmission rates for target and nontarget conditions.Results: The study included 48 137 102 hospitalizations of 20 351 161 Medicare beneficiaries. In January 2008, the mean readmission rates for AMI, HF, pneumonia, and nontarget conditions were 21.9%, 27.5%, 20.1%, and 18.4%, respectively, at hospitals later subject to financial penalties and 18.7%, 24.2%, 17.4%, and 15.7% at hospitals not subject to penalties. Between January 2008 and March 2010, prior to HRRP announcement, readmission rates were stable across hospitals (except AMI at nonpenalty hospitals). Following announcement of HRRP (March 2010), readmission rates for both target and nontarget conditions declined significantly faster for patients at hospitals later subject to financial penalties compared with those at nonpenalized hospitals (for AMI, additional decrease of -1.24 [95% CI, -1.84 to -0.65] percentage points per year relative to nonpenalty discharges; for HF, -1.25 [95% CI, -1.64 to -0.86]; for pneumonia, -1.37 [95% CI, -1.80 to -0.95]; and for nontarget conditions, -0.27 [95% CI, -0.38 to -0.17]; P < .001 for all). For penalty hospitals, readmission rates for target conditions declined significantly faster compared with nontarget conditions (for AMI, additional decline of -0.49 [95% CI, -0.81 to -0.16] percentage points per year relative to nontarget conditions [P = .004]; for HF, -0.90 [95% CI, -1.18 to -0.62; P < .001]; and for pneumonia, -0.57 [95% CI, -0.92 to -0.23; P < .001]). In contrast, among nonpenalty hospitals, readmissions for target conditions declined similarly or more slowly compared with nontarget conditions (for AMI, additional increase of 0.48 [95% CI, 0.01-0.95] percentage points per year [P = .05]; for HF, 0.08 [95% CI, -0.30 to 0.46; P = .67]; for pneumonia, 0.53 [95% CI, 0.13-0.93; P = .01]). After HRRP implementation in October 2012, the rate of change for readmission rates plateaued (P < .05 for all except pneumonia at nonpenalty hospitals), with the greatest relative change observed among hospitals subject to financial penalty.Conclusions and Relevance: Medicare fee-for-service patients at hospitals subject to penalties under the HRRP had greater reductions in readmission rates compared with those at nonpenalized hospitals. Changes were greater for target vs nontarget conditions for patients at the penalized hospitals but not at the other hospitals. [ABSTRACT FROM AUTHOR]

Importance: Little contemporary information is available about comparative performance between Veterans Affairs (VA) and non-VA hospitals, particularly related to mortality and readmission rates, 2 important outcomes of care.Objective: To assess and compare mortality and readmission rates among men in VA and non-VA hospitals.Design, Setting, and Participants: Cross-sectional analysis involving male Medicare fee-for-service beneficiaries aged 65 years or older hospitalized between 2010 and 2013 in VA and non-VA acute care hospitals for acute myocardial infarction (AMI), heart failure (HF), or pneumonia using the Medicare Standard Analytic Files and Enrollment Database together with VA administrative claims data. To avoid confounding geographic effects with health care system effects, we studied VA and non-VA hospitals within the same metropolitan statistical area (MSA).Exposures: Hospitalization in a VA or non-VA hospital in MSAs that contained at least 1 VA and non-VA hospital.Main Outcomes and Measures: For each condition, 30-day risk-standardized mortality rates and risk-standardized readmission rates for VA and non-VA hospitals. Mean aggregated within-MSA differences in mortality and readmission rates were also assessed.Results: We studied 104 VA and 1513 non-VA hospitals, with each condition-outcome analysis cohort for VA and non-VA hospitals containing at least 7900 patients (men; ≥65 years), in 92 MSAs. Mortality rates were lower in VA hospitals than non-VA hospitals for AMI (13.5% vs 13.7%, P = .02; -0.2 percentage-point difference) and HF (11.4% vs 11.9%, P = .008; -0.5 percentage-point difference), but higher for pneumonia (12.6% vs 12.2%, P = .045; 0.4 percentage-point difference). In contrast, readmission rates were higher in VA hospitals for all 3 conditions (AMI, 17.8% vs 17.2%, 0.6 percentage-point difference; HF, 24.7% vs 23.5%, 1.2 percentage-point difference; pneumonia, 19.4% vs 18.7%, 0.7 percentage-point difference, all P < .001). In within-MSA comparisons, VA hospitals had lower mortality rates for AMI (percentage-point difference, -0.22; 95% CI, -0.40 to -0.04) and HF (-0.63; 95% CI, -0.95 to -0.31), and mortality rates for pneumonia were not significantly different (-0.03; 95% CI, -0.46 to 0.40); however, VA hospitals had higher readmission rates for AMI (0.62; 95% CI, 0.48 to 0.75), HF (0.97; 95% CI, 0.59 to 1.34), or pneumonia (0.66; 95% CI, 0.41 to 0.91).Conclusions and Relevance: Among older men with AMI, HF, or pneumonia, hospitalization at VA hospitals, compared with hospitalization at non-VA hospitals, was associated with lower 30-day risk-standardized all-cause mortality rates for AMI and HF, and higher 30-day risk-standardized all-cause readmission rates for all 3 conditions, both nationally and within similar geographic areas, although absolute differences between these outcomes at VA and non-VA hospitals were small.

IMPORTANCE In a period of dynamic change in health care technology, delivery, and behaviors, tracking trends in health and health care can provide a perspective on what is being achieved. OBJECTIVE To comprehensively describe national trends in mortality, hospitalizations, and expenditures in the Medicare fee-for-service population between 1999 and 2013. DESIGN, SETTING, AND PARTICIPANTS Serial cross-sectional analysis of Medicare beneficiaries aged 65 years or older between 1999 and 2013 using Medicare denominator and inpatient files. MAIN OUTCOMES AND MEASURES For all Medicare beneficiaries, trends in all-cause mortality; for fee-for-service beneficiaries, trends in all-cause hospitalization and hospitalization-associated outcomes and expenditures. Geographic variation, stratified by key demographic groups, and changes in the intensity of care for fee-for-service beneficiaries in the last 1, 3, and 6 months of life were also assessed. RESULTS The sample consisted of 68 374 904 unique Medicare beneficiaries (fee-for-service and Medicare Advantage). All-cause mortality for all Medicare beneficiaries declined from 5.30% in 1999 to 4.45% in 2013 (difference, 0.85 percentage points; 95% CI, 0.83-0.87). Among fee-for-service beneficiaries (n = 60 056 069), the total number of hospitalizations per 100 000 person-years decreased from 35 274 to 26 930 (difference, 8344; 95% CI, 8315-8374). Mean inflation-adjusted inpatient expenditures per Medicare fee-for-service beneficiary declined from $3290 to $2801 (difference, $489; 95% CI, $487-$490). Among fee-for-service beneficiaries in the last 6 months of life, the number of hospitalizations decreased from 131.1 to 102.9 per 100 deaths (difference, 28.2; 95% CI, 27.9-28.4). The percentage of beneficiaries with 1 or more hospitalizations decreased from 70.5 to 56.8 per 100 deaths (difference, 13.7; 95% CI, 13.5-13.8), while the inflation-adjusted inpatient expenditure per death increased from $15 312 in 1999 to $17 423 in 2009 and then decreased to $13 388 in 2013. Findings were consistent across geographic and demographic groups. CONCLUSIONS AND RELEVANCE Among Medicare fee-for-service beneficiaries aged 65 years or older, all-cause mortality rates, hospitalization rates, and expenditures per beneficiary decreased from 1999 to 2013. In the last 6 months of life, total hospitalizations and inpatient expenditures decreased in recent years. [ABSTRACT FROM AUTHOR]

The article focuses on a study regarding the evaluation of readmission and timing among Medicare beneficiaries who are readmitted for heart failure (HF), acute myocardial infarction (MI) and pneumonia. It mentions that hospital readmissions report poor health care facility and states that the U.S. Centers for Medicare and Medicaid Services (CMS) has started public reporting of outcomes for improving the hospital care quality. The study reveals that 30-day readmissions were frequent throughout the month after rehospitalization for HF, MI and pneumonia. It also presents statistics which depict the readmission of patients.

The article discusses a study which examined changes in the rate of hospitalization due to heart failure (HF) and one-year mortality rate in fee-for-service Medicare beneficiaries in the U.S. from 1998 to 2008. HF hospitalization and mortality rates were analyzed nationally and by state or territory. The study found that the age, sex and race-adjusted HF hospitalization rate decreased to 2007 per 100,000 person-years in 2008 from 2845 in 1998. The lowest rate of decline was observed in African American men. Risk-adjusted one-year mortality dropped to 29.6% in 2008 compared with 31.7% in 1999. The study showed an increase in some comorbidities such as hypertension and renal dysfunction in patients hospitalized for HF.

The article discusses a study on outcomes of carotid stenting based on operator experience in the U.S. from 2005 to 2007. The study evaluated the link between outcomes and two variables of operator experience, namely, annual volume and experience at the time of the procedure among new operators who performed carotid stenting for the first time following a national coverage decision by the Centers for Medicare & Medicaid Services (CMS). Administrative data collected from fee-for-service Medicare beneficiaries aged 65 years old and above was used under the study. Higher 30-day mortality was observed among patients treated by operators with lower annual volumes and patients treated early during a new operator's experience.

The article discusses a study which investigated trends in and economic implications of the use of fibrates in the U.S. and Canada. The researchers also examined the relationship between differences in the availability and use of brand-name versus generic formulations of fenofibrate in both countries. The population-level, observational cohort study utilized IMS Health data from both countries between January 2002 and December 2009. It was found that there has been an increase in prescriptions for fibrates in the U.S., while prescriptions in Canada remained stable.

The article focuses on a study which evaluated the association between automated external defibrillators (AEDs) use and survival for in-hospital cardiac arrest. The researchers examined 11,695 hospitalized patients who experienced cardiac arrests between January 1, 2000 to August 26, 2008 at U.S. hospitals following the introduction of AEDs on general and hospital wards. Study results indicated that hospitalized patients with cardiac arrest and use of AED were not associated with improved survival.

The article discusses a study which described the temporal changes in length of stay, discharge disposition, and short-term outcomes among older U.S. patients hospitalized for heart failure. The observational study examined 6,955,461 Medicare fee-for-service hospitalizations for heart failure between 1993 and 2006. The researchers found that the mean length of stay decreased from 8.81 days to 6.33 days between 1993 and 2006. The importance of examining an episode of acute care during a standardized period of assessment is also highlighted by the study.

The article offers information on a study which determined the link between lack of health insurance and financial concerns about accessing care among those with health insurance, and the time from symptom onset to hospital presentation during acute myocardial infarction (AMI). Data analyzed by researchers were from a registry of AMI patients enrolled between April 11, 2005 and December 31, 2008 at 24 U.S. hospitals. Medical records were utilized to determine insurance information, while information on financial concerns was taken from structured interviews. A detailed discussion on the research findings is presented.

The article focuses on a study which was designed to characterize the attitudes, experiences and training expectations of general surgery residents in the U.S. The study included a survey of all general surgery residents and was conducted after the American Board of Surgery In-Training Examination. Most of the study subjects claimed that they are satisfied with training and supportive peer relationships. However, there are residents who reported unmet needs and apprehensions related to training and careers. Study authors concluded that the attitude, experiences and training expectations of general surgery residents reflect high levels of satisfaction.

The article focuses on an observational study which estimated hospital-level 30-day risk-standardized mortality rates (RSMRs) for patients discharged with acute myocardial infarction (AMI). Administrative data and a validated risk model were used to evaluate 3,195,672 discharges in 2,755,370 patients discharged from nonfederal acute care hospitals in the U.S. between January 1, 1995 to December 31, 2006. A significant decrease was observed in the risk-standardized hospital mortality rate for Medicare patients discharged with AMI, as well as between-hospital variation.

The article presents the results of a statistical study which used the Surveillance, Epidemiology and End Results Medicare database to determine the impact of increased Medicare coverage for colonoscopy screening on the early detection of colon cancer among patients over age 67. The medical information of over 44,000 patients was included in the sample. Medicare's reimbursement policy was widened in 1998, and again in 2001. The expanded coverage was found to have increased the use of colonoscopies, and clearly improved the subjects' chances for early diagnosis of proximal colon lesions. Details of the methodology and results are provided.

The article discusses the underrepresentation of chronic renal disease in randomized controlled trials of cardiovascular disease. Nine million people in the United States population have chronic kidney disease. And of these many have cardiovascular disease (CVD), specifically coronary artery disease and chronic congestive heart failure. Recent studies suggest that renal disease independently portends increased morbidity and mortality in CVD. Because renal disease is so prevalent in CVD and the pathophysiologic processes so different from those with normal renal functions, it is important to have data on the subgroup of renal diseases. Patients with renal diseases must not be excluded, but included in CVD trials which need to be designated for this population of chronic renal patients.

Comments on the push for regional treatment centers for patients with acute coronary syndromes. Planning for regionalized care begun by the State of Maryland; Presentation of concerns for this approach to patient care and possible unintended consequences; Arguments for the benefits of the ACS centers, which are based on studies with notable limitations; Lack of clear consensus on the specific nature of ACS regionalization; Risks to patients; Concerns about how the direct admission of ACS patients will be handled; Economic implications; Concern that regionalization may be the end of quality care at non-ACS facilities; Conclusion and belief there is not enough data to support the value of these centers at this time.

Context Nonwhite patients experience significantly longer times to fibrinolytic therapy (door-to-drug times) and percutaneous coronary intervention (door-to-balloon times) than white patients, raising concerns of health care disparities, but the reasons for these patterns are poorly understood. Objectives To estimate race/ethnicity differences in door-to-drug and door-to-balloon times for patients receiving primary reperfusion for ST-segment elevation myocardial infarction; to examine how sociodemographic factors, insurance status, clinical characteristics, and hospital features mediate racial/ethnic differences. Design, Setting, and Patients Retrospective, observational study using admission and treatment data from the National Registry of Myocardial Infarction (NRMI) for a US cohort of patients with ST-segment elevation myocardial infarction or left bundle-branch block and receiving reperfusion therapy. Patients (73,032 receiving fibrinolytic therapy; 37,143 receiving primary percutaneous coronary intervention) were admitted from January 1, 1999, through December 31, 2002, to hospitals participating in NRMI 3 and 4. Main Outcome Measure Minutes between hospital arrival and acute reperfusion therapy. Results Door-to-drug times were significantly longer for patients identified as African American/black (41.1 minutes), Hispanic (36.1 minutes), and Asian/Pacific Islander (37.4 minutes), compared with patients identified as white (33.8 minutes) (P<.01 for all). Door-to-balloon times for patients identified as African American/black (122.3 minutes) or Hispanic (114.8 minutes) were significantly longer than for patients identified as white (103.4 minutes) (P<.001 for both). Racial/ethnic differences were still significant but were substantially reduced after accounting for differences in mean times to treatment for the hospitals in which patients were treated; significant racial/ethnic differences persisted after further adjustment for sociodemographic characte...

Context: According to package inserts, metformin is contraindicated in diabetic patients receiving drug treatment for heart failure therapy, and thiazolidinediones are not recommended in diabetic patients with symptoms of advanced heart failure. Little is known about patterns of use of these antihyperglycemic drugs in diabetic patients with heart failure. Objective: To determine the proportions of patients hospitalized with heart failure and concomitant diabetes treated with metformin or thiazolidinediones. Design: Serial cross-sectional measurements using data from retrospective medical record abstraction. Setting: Nongovernmental acute care hospitals in the United States. Patients: Two nationally representative samples of Medicare beneficiaries hospitalized with the primary diagnosis of heart failure and concomitant diabetes between April 1998 and March 1999 and between July 2000 and June 2001. Main Outcome Measures: The prescription of either metformin or a thiazolidinedione at hospital discharge. Results: In the 1998-1999 sample (n = 12 505), 7.1% of patients were discharged with a prescription for metformin, 7.2% with a prescription for a thiazolidinedione, and 13.5% with a prescription for either drug. In the 2000-2001 sample (n = 13 158), metformin use increased to 11.2%, thiazolidinedione use to 16.1%, and use of either drug to 24.4% (P<.001 for all comparisons). Similar increases were seen among patients of all age groups, all races, and both sexes. Conclusions: The use of metformin and thiazolidinediones is common and has increased rapidly in Medicare beneficiaries with diabetes and heart failure in direct contrast with explicit warnings against this practice by the Food and Drug Administration. Further studies to establish the safety and effectiveness of this practice are needed to ensure optimal care of patients with diabetes and heart failure. [ABSTRACT FROM AUTHOR]

The article focuses on the option of shared decision making offered to patients instead of the earlier conventional consent procedures, particularly for hip replacement and knee osteoarthritis. It discusses how the physician reviews the options, also informing the patients about the risks involved in the treatment option. It also talks about the legislative route by Washington State encouraging shared decision making.

The article discusses the need to revitalize reasonable-patient standards for informed consent through shared decision making. Topics include policy initiatives to advance informed consent with the reasonable-patient standard, informed consent and high-value patient-centered care, and the importance of implementing value-based payment models that recognize high-quality informed consent practices.

The author reflects on the implications of patient centeredness in medical care in the U.S. He cites the definition of patient centeredness according to the Institute of Medicine (IOM), along with how patient-centered care could be achieved. He ponders the possible oppositions to the implementation of patient-centered care in the U.S., including patient anxiety and the advent of issues about informed consent. The author argues that patient-centered care could provide patients with more informed decision making capacity.

A reply is presented to a response to the authors' article "Association of Admission to Veterans Affairs Hospitals vs non-Veterans Affairs Hospitals With Mortality and Readmission Rates Among Older Men Hospitalized With Acute Myocardial Infarction, Heart Failure, or Pneumonia."

Presents a reply to a letter to the editor of "The Journal of the American Medical Association" regarding acute coronary syndromes and regionalization of care. Discussion of an article by Rathore and colleagues found in a previous issue of the journal.

The article discusses a proposal to conduct an external review of data related to research on the safety and efficacy of bone morphogenetic protein-2 (BMP-2). A spinal fusion product called Infuse Bone Graft from Medtronic Inc. contains recombinant BMP-2, which was approved by the U.S. Food and Drug Administration (FDA) for single level anterior interbody lumbar fusion in 2002. Skepticism towards the product is said to have increased as its use increased. There were conflict-of-interest issues raised in different periodicals such as the "Milwaukee Journal Sentinel" and "The Spine Journal." Professor Harlan M. Krumholz of Yale University School of Medicine in New Haven, Connecticut conceptualized the external review, which is being supported by Medtronic.
