      Prominent publications by Harlan M Krumholz

      KOL-Index: 24469

      IMPORTANCE: To better guide strategies intended to reduce high rates of 30-day readmission after hospitalization for heart failure (HF), acute myocardial infarction (MI), or pneumonia, further information is needed about readmission diagnoses, readmission timing, and the relationship of both to patient age, sex, and race.

      OBJECTIVE: To examine readmission diagnoses and timing among Medicare beneficiaries readmitted within 30 days after hospitalization for HF, acute MI, or ...

      KOL-Index: 21465

      Importance: Acute myocardial infarction (AMI) complicated by cardiogenic shock is associated with substantial morbidity and mortality. Although intravascular microaxial left ventricular assist devices (LVADs) provide greater hemodynamic support as compared with intra-aortic balloon pumps (IABPs), little is known about clinical outcomes associated with intravascular microaxial LVAD use in clinical practice.

      Objective: To examine outcomes among patients undergoing percutaneous coronary ...

      BACKGROUND: Hypertension is common in China and its prevalence is rising, yet it remains inadequately controlled. Few studies have the capacity to characterise the epidemiology and management of hypertension across many heterogeneous subgroups. We did a study of the prevalence, awareness, treatment, and control of hypertension in China and assessed their variations across many subpopulations.

      METHODS: We made use of data generated in the China Patient-Centered Evaluative Assessment of ...

      OBJECTIVE: To characterize the absolute risks for older patients of readmission to hospital and death in the year after hospitalization for heart failure, acute myocardial infarction, or pneumonia.

      DESIGN: Retrospective cohort study.

      SETTING: 4767 hospitals caring for Medicare fee for service beneficiaries in the United States, 2008-10.

      PARTICIPANTS: More than 3 million Medicare fee for service beneficiaries, aged 65 years or more, surviving hospitalization for heart failure, acute ...

      KOL-Index: 19935

      Importance: The US Hospital Readmissions Reduction Program (HRRP) was associated with reduced readmissions among Medicare beneficiaries hospitalized for acute myocardial infarction (AMI), heart failure (HF), and pneumonia. It is important to assess whether there has been a signal for concomitant harm with an increase in mortality.

      Objective: To evaluate whether the announcement or the implementation of HRRP was associated with an increase in either in-hospital or 30-day postdischarge ...

      KOL-Index: 19886

      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 ...

      CONTEXT: Medicare's reimbursement policy was changed in 1998 to provide coverage for screening colonoscopies for patients with increased colon cancer risk, and expanded further in 2001 to cover screening colonoscopies for all individuals.

      OBJECTIVE: To determine whether the Medicare reimbursement policy changes were associated with an increase in either colonoscopy use or early stage colon cancer diagnosis.

      DESIGN, SETTING, AND PARTICIPANTS: Patients in the Surveillance, Epidemiology, ...

      BACKGROUND: Ezetimibe lowers low-density lipoprotein cholesterol, but current lipid-lowering guidelines in the United States and Canada do not recommend it as a first option for either primary or secondary prevention. We sought to describe the adoption of ezetimibe relative to that of other lipid-lowering agents and compare its use in the two countries.

      METHODS: We conducted a population-level, cohort study using data from January 2002 to December 2006, provided by IMS Health, to ...

      IMPORTANCE: The Centers for Medicare & Medicaid Services publicly reports hospital 30-day, all-cause, risk-standardized mortality rates (RSMRs) and 30-day, all-cause, risk-standardized readmission rates (RSRRs) for acute myocardial infarction, heart failure, and pneumonia. The evaluation of hospital performance as measured by RSMRs and RSRRs has not been well characterized.

      OBJECTIVE: To determine the relationship between hospital RSMRs and RSRRs overall and within subgroups defined by ...

      KOL-Index: 19500

      OBJECTIVE: To examine the effect of the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) hypertension guidelines on the prevalence of hypertension and eligibility for initiation and intensification of treatment in nationally representative populations from the United States and China.

      DESIGN: Observational assessment of nationally representative data.

      SETTING: US National Health and Nutrition Examination Survey (NHANES) for the most recent two cycles (2013-14, ...

      Importance: Although studies have described differences in hospital outcomes by patient race and socioeconomic status, it is not clear whether such disparities are driven by hospitals themselves or by broader systemic effects.

      Objective: To determine patterns of racial and socioeconomic disparities in outcomes within and between hospitals for patients with acute myocardial infarction, heart failure, and pneumonia.

      Design, Setting, and Participants: Retrospective cohort study initiated ...

      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: ...

      KOL-Index: 19006

      IMPORTANCE: The increasing intensity of diabetes mellitus management over the past decade may have resulted in lower rates of hyperglycemic emergencies but higher rates of hospital admissions for hypoglycemia among older adults. Trends in these hospitalizations and subsequent outcomes are not known.

      OBJECTIVE: To characterize changes in hyperglycemia and hypoglycemia hospitalization rates and subsequent mortality and readmission rates among older adults in the United States over a ...

      KOL-Index: 18893

      OBJECTIVES: To examine the association between income inequality and the risk of mortality and readmission within 30 days of hospitalization.

      DESIGN: Retrospective cohort study of Medicare beneficiaries in the United States. Hierarchical, logistic regression models were developed to estimate the association between income inequality (measured at the US state level) and a patient's risk of mortality and readmission, while sequentially controlling for patient, hospital, other state, and ...

      BACKGROUND: Despite the importance of ST-segment elevation myocardial infarction (STEMI) in China, no nationally representative studies have characterised the clinical profiles, management, and outcomes of this cardiac event during the past decade. We aimed to assess trends in characteristics, treatment, and outcomes for patients with STEMI in China between 2001 and 2011.

      METHODS: In a retrospective analysis of hospital records, we used a two-stage random sampling design to create a ...
