Legalization of medical marijuana has been one of the most controversial areas of state policy change over the past twenty years. However, little is known about whether medical marijuana is being used clinically to any significant degree. Using data on all prescriptions filled by Medicare Part D enrollees from 2010 to 2013, we found that the use of prescription drugs for which marijuana could serve as a clinical alternative fell significantly, once a medical marijuana law was implemented. National overall reductions in Medicare program and enrollee spending when states implemented medical marijuana laws were estimated to be $165.2 million per year in 2013. The availability of medical marijuana has a significant effect on prescribing patterns and spending in Medicare Part D.

The United States has poorer child health outcomes than other wealthy nations despite greater per capita spending on health care for children. To better understand this phenomenon, we examined mortality trends for the US and nineteen comparator nations in the Organization for Economic Cooperation and Development for children ages 0-19 from 1961 to 2010 using publicly available data. While child mortality progressively declined across all countries, mortality in the US has been higher than in peer nations since the 1980s. From 2001 to 2010 the risk of death in the US was 76 percent greater for infants and 57 percent greater for children ages 1-19. During this decade, children ages 15-19 were eighty-two times more likely to die from gun homicide in the US. Over the fifty-year study period, the lagging US performance amounted to over 600,000 excess deaths. Policy interventions should focus on infants and on children ages 15-19, the two age groups with the greatest disparities, by addressing perinatal causes of death, automobile accidents, and assaults by firearm.

Much has been written about the relationship between high medical expenses and the likelihood of filing for bankruptcy, but the relationship between receiving a cancer diagnosis and filing for bankruptcy is less well understood. We estimated the incidence and relative risk of bankruptcy for people age twenty-one or older diagnosed with cancer compared to people the same age without cancer by conducting a retrospective cohort analysis that used a variety of medical, personal, legal, and bankruptcy sources covering the Western District of Washington State in US Bankruptcy Court for the period 1995-2009. We found that cancer patients were 2.65 times more likely to go bankrupt than people without cancer. Younger cancer patients had 2-5 times higher rates of bankruptcy than cancer patients age sixty-five or older, which indicates that Medicare and Social Security may mitigate bankruptcy risk for the older group. The findings suggest that employers and governments may have a policy role to play in creating programs and incentives that could help people cover expenses in the first year following a cancer diagnosis.

We examined the impact of California’s early Medicaid expansion under the Affordable Care Act on the use of payday loans, a form of high-interest borrowing used by low- and middle-income Americans. Using a data set for the period 2009-13 (roughly twenty-four months before and twenty-four months after the 2011-12 Medicaid expansion) that covered the universe of payday loans from five large payday lenders with locations around the United States, we used a difference-in-differences research design to assess the effect of the expansion on payday borrowing, comparing trends in early-expansion counties in California to those in counties nationwide that did not expand early. The early Medicaid expansion was associated with an 11 percent reduction in the number of loans taken out each month. It also reduced the number of unique borrowers each month and the amount of payday loan debt. We were unable to determine precisely how and for whom the expansion reduced payday borrowing, since to our knowledge, no data exist that directly link payday lending to insurance status. Nonetheless, our results suggest that Medicaid reduced the demand for high-interest loans and improved the financial health of American families.

Firearm-related deaths are the third leading cause of injury-related deaths in the United States. Yet limited data exist on contemporary epidemiological trends and risk factors for firearm-related injuries. Using data from the Nationwide Emergency Department Sample, we report epidemiological trends and quantify the clinical and financial burden associated with emergency department (ED) visits for firearm-related injuries. We identified 150,930 patients-representing a weighted total of 704,916 patients nationally-who presented alive to the ED in the period 2006-14 with firearm-related injuries. Such injuries were approximately nine times more common among male than female patients and highest among males ages 20-24. Of the patients who presented alive to the ED, 37.2 percent were admitted to inpatient care, while 8.3 percent died during their ED visit or inpatient admission. The mean per person ED and inpatient charges were $5,254 and $95,887, respectively, resulting in an annual financial burden of approximately $2.8 billion in ED and inpatient charges. Although future research is warranted to better understand firearm-related injuries, policy makers might consider implementing universal background checks for firearm purchases and limiting access to firearms for people with a history of violence or previous convictions to reduce the clinical and financial burden associated with these injuries.

Mexico implemented a 1 peso per liter excise tax on sugar-sweetened beverages on January 1, 2014, and a previous study found a 6 percent reduction in purchases of taxed beverages in 2014. In this study we estimated changes in beverage purchases for 2014 and 2015. We used store purchase data for 6,645 households from January 2012 to December 2015. Changes in purchases of taxed and untaxed beverages in the study period were estimated using two models, which compared 2014 and 2015 purchases with predicted (counterfactual) purchases based on trends in 2012-13. Purchases of taxed beverages decreased 5.5 percent in 2014 and 9.7 percent in 2015, yielding an average reduction of 7.6 percent over the study period. Households at the lowest socioeconomic level had the largest decreases in purchases of taxed beverages in both years. Purchases of untaxed beverage increased 2.1 percent in the study period. Findings from Mexico may encourage other countries to use fiscal policies to reduce consumption of unhealthy beverages along with other interventions to reduce the burden of chronic disease.

Populationwide mammography screening has been associated with a substantial rise in false-positive mammography findings and breast cancer overdiagnosis. However, there is a lack of current data on the associated costs in the United States. We present costs due to false-positive mammograms and breast cancer overdiagnoses among women ages 40-59, based on expenditure data from a major US health care insurance plan for 702,154 women in the years 2011-13. The average expenditures for each false-positive mammogram, invasive breast cancer, and ductal carcinoma in situ in the twelve months following diagnosis were $852, $51,837 and $12,369, respectively. This translates to a national cost of $4 billion each year. The costs associated with false-positive mammograms and breast cancer overdiagnoses appear to be much higher than previously documented. Screening has the potential to save lives. However, the economic impact of false-positive mammography results and breast cancer overdiagnoses must be considered in the debate about the appropriate populations for screening.

Each year US physician practices in four common specialties spend, on average, 785 hours per physician and more than $15.4 billion dealing with the reporting of quality measures. While much is to be gained from quality measurement, the current system is unnecessarily costly, and greater effort is needed to standardize measures and make them easier to report.

Many immigrants in the United States are working-age taxpayers; few are elderly beneficiaries of Medicare. This demographic profile suggests that immigrants may be disproportionately subsidizing the Medicare Trust Fund, which supports payments to hospitals and institutions under Medicare Part A. For immigrants and others, we tabulated Trust Fund contributions and withdrawals (that is, Trust Fund expenditures on their behalf) using multiple years of data from the Current Population Survey and the Medical Expenditure Panel Survey. In 2009 immigrants made 14.7 percent of Trust Fund contributions but accounted for only 7.9 percent of its expenditures-a net surplus of $13.8 billion. In contrast, US-born people generated a $30.9 billion deficit. Immigrants generated surpluses of $11.1-$17.2 billion per year between 2002 and 2009, resulting in a cumulative surplus of $115.2 billion. Most of the surplus from immigrants was contributed by noncitizens and was a result of the high proportion of working-age taxpayers in this group. Policies that restrict immigration may deplete Medicare’s financial resources.

Recent closures of rural obstetric units and entire hospitals have exacerbated concerns about access to care for more than twenty-eight million women of reproductive age living in rural America. Yet the extent of recent obstetric unit closures has not yet been measured. Using national data, we found that 9 percent of rural counties experienced the loss of all hospital obstetric services in the period 2004-14. In addition, another 45 percent of rural US counties had no hospital obstetric services at all during the study period. That left more than half of all rural US counties without hospital obstetric services. Counties with fewer obstetricians and family physicians per women of reproductive age and per capita, respectively; a higher percentage of non-Hispanic black women of reproductive age; and lower median household incomes and those in states with more restrictive Medicaid income eligibility thresholds for pregnant women had higher odds of lacking hospital obstetric services. The same types of counties were also more likely to experience the loss of obstetric services, which highlights the challenge of providing adequate geographic access to obstetric care in vulnerable and underserved rural communities.
