The decreasing effectiveness of antimicrobial agents is a global public health threat, yet risk factors for community-acquired antimicrobial resistance (CA-AMR) in low-income settings have not been clearly elucidated. Our aim was to identify risk factors for CA-AMR with extended-spectrum β-lactamase (ESBL)–producing organisms among urban-dwelling women in India. We collected microbiological and survey data in an observational study of primigravidae women in a public hospital in Hyderabad, India.
ACA Marketplace Premiums and Competition Among Hospitals and Physician Practices
In this study published in the American Journal of Managed Care, the authors found that premiums for ACA Marketplace plans were higher in rating areas in which physician, hospital, and insurance markets were less competitive.
Robust relationship between air quality and infant mortality in Africa
Poor air quality is thought to be an important mortality risk factor globally, but there is little direct evidence from the developing world on how mortality risk varies with changing exposure to ambient particulate matter. Current global estimates apply exposure-response relationships that have been derived mostly from wealthy, mid-latitude countries to spatial population data, and these estimates remain unvalidated across large portions of the globe.
Does Diversity Matter for Health? Experimental Evidence from Oakland
Learning on the Job: Evidence from Physicians in Training
Abstract: Learning on the job creates a tradeoff in team decisions: Workers with less knowledge have less to contribute to team decisions, but experiential learning may require that trainees also have a stake in decisions to learn. This paper studies learning and influence in team decisions among physicians trainees. Exploiting a discontinuity in relative experience, I find reduced-form evidence of influence due to seniority between trainees.
Industry Input in Policymaking: Evidence from Medicare
Abstract: In setting prices for physician services, Medicare solicits input from a committee that evaluates proposals from industry. We investigate whether this arrangement leads to prices biased toward the interests of committee members. We find that increasing a measure of affiliation between the committee and proposers by one standard deviation increases prices by 10%, demonstrating a pathway for regulatory capture. We then evaluate the effect of affiliation on the quality of information used in price-setting.
Is Single Payer the Answer for the US Health Care System?
The recent challenges to the Affordable Care Act (ACA), which has increased the number of individuals with health insurance in the United States but has had little effect on cost, has revived the debate about a single-payer health care system.
Drug Companies’ Liability for the Opioid Epidemic
The opioid epidemic has claimed more than 300,000 lives in the United States since 20001
Family Planning and Fertility Behavior: Evidence from Twentieth Century Malaysia
There is longstanding debate about the contribution of family planning programs to fertility decline. Studying the staggered introduction of family planning across Malaysia during the 1960s and 1970s, we find modest responses in fertility behavior. Higher (but not lower) parity birth hazards declined by one-quarter—but imply only a 5 percent decline in the overall annual probability of birth. Age at marriage rose by 0.48 years, but birth spacing conditional on this did not otherwise change.
Relationship between season of birth, temperature exposure, and later life wellbeing
We study how exposure to extreme temperatures in early periods of child development is related to adult economic outcomes measured 30 y later. Our analysis uses administrative earnings records for over 12 million individuals born in the United States between 1969 and 1977, linked to fine-scale, daily weather data and location and date of birth.
Marketplace Plans Provide Risk Protection, But Actuarial Values Overstate Realized Coverage For Most Enrollees
The Affordable Care Act (ACA) has increased the number of Americans with health insurance. Yet many policy makers and consumers have questioned the value of Marketplace plan coverage because of the generally high levels of cost sharing. We simulated out-of-pocket spending for bronze, silver, or gold Marketplace plans (those having actuarial values of 60 percent, 70 percent, and 80 percent, respectively).
Characteristics Associated With Decreased or Increased Mortality Risk From Glycemic Therapy Among Patients With Type 2 Diabetes and High Cardiovascular Risk: Machine Learning Analysis of the ACCORD Trial
Validation of Risk Equations for Complications of Type 2 Diabetes (RECODe) Using Individual Participant Data From Diverse Longitudinal Cohorts in the U.S.
PCSK9 Inhibitors Economics and Policy
Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors substantially reduce low-density lipoprotein cholesterol, but it is presently unclear whether they also reduce mortality. The list prices of PCSK9 inhibitors in the United States (>$14,500 per year) are >100× higher than generic statins, and only a small fraction of their higher cost is likely to be recovered by prevention of cardiovascular events.
Supplemental Nutrition Assistance Program (SNAP) Participation and Health Care Expenditures Among Low-Income Adults
Objective
To determine whether the Supplemental Nutrition Assistance Program (SNAP), which addresses food insecurity, can reduce health care expenditures.
Drug-Free Interventions to Reduce Pain or Opioid Consumption After Total Knee Arthroplasty A Systematic Review and Meta-analysis
To systematically review and meta-analyze evidence of nonpharmacological interventions for postoperative pain management after total knee arthroplasty.
Social Isolation and Medicare Spending: Among Older Adults, Objective Isolation Increases Expenditures While Loneliness Does Not
Objective: The purpose of this study was to evaluate the impact of objective isolation and loneliness on Medicare spending and outcomes. Method: We linked Health and Retirement Study data to Medicare claims to analyze objective isolation (scaled composite of
Family Ruptures, Stress, and the Mental Health of the Next Generation
This paper studies how in utero exposure to maternal stress from family ruptures affects later mental health. We find that prenatal exposure to the death of a maternal relative increases take-up of ADHD medications during childhood and anti-anxiety and depression medications in adulthood. Further, family ruptures during pregnancy depress birth outcomes and raise the risk of perinatal complications necessitating hospitalization. Our results suggest large welfare gains from preventing fetal stress from family ruptures and possibly from economically induced stressors such as unemployment.
High Levels Of Capitation Payments Needed To Shift Primary Care Toward Proactive Team And Nonvisit Care
Tuskegee and the Health of Black Men
For forty years, the Tuskegee Study of Untreated Syphilis in the Negro Male passively monitored hundreds of adult black males with syphilis despite the availability of effective treatment.
Childhood Illness and the Gender Gap in Adolescent Education in Low- and Middle-Income Countries
Achieving gender equality in education is an important development goal. We tested the hypothesis that the gender gap in adolescent education is accentuated by illnesses among young children in the household.
The Evolving Story of Overlapping Surgery
In December 2015, a Boston Globe investigation of Massachusetts General Hospital (MGH) sparked investigations into concurrent and overlapping surgery. Overlapping surgery refers to operations performed by the same primary surgeon such that the start of one surgery overlaps with the end of another. A qualified practitioner finishes noncritical aspects of the first operation while the primary surgeon moves to the next operation.
Implementation science for ambulatory care safety: a novel method to develop context-sensitive interventions to reduce quality gaps in monitoring high-risk patients.
Missed evidence-based monitoring in high-risk conditions (e.g., cancer) leads to delayed diagnosis. Current technological solutions fail to close this safety gap. In response, we aim to demonstrate a novel method to identify common vulnerabilities across clinics and generate attributes for context-flexible population-level monitoring solutions for widespread implementation to improve quality.
Ten years after the financial crisis: The long reach of austerity and its global impacts on health
The global financial crisis starting in 2007 prompted national governments around the world, and notably many within the European Union, to implement austerity measures. Similar to structural adjustment programs (SAPs) implemented throughout the developing world since the 1980s, much of the pressure to adopt and enforce austerity measures has been levied by global financial institutions such as the IMF.
Malaria control adds to the evidence for health aid effectiveness
The new United States administration’s first budget proposal, previewed in March and released in May, 2017, includes deep cuts to foreign aid, cycling this thorny issue back into the American limelight.
