Mandatory Health Care Provider Counseling For Parents Led To A Decline In Vaccine Exemptions In California

Sep. 10, 2018

Malia Jones, Alison M. Buttenheim, Daniel Salmon, and Saad B. Omer

ABSTRACT [FROM JOURNAL] 

Receipt of childhood vaccinations in the US has been declining, and outbreaks of preventable infectious diseases have become more common. In response, in 2014 California implemented a policy change for exemptions from mandatory vaccines for school enrollment. Data on fifteen successive cohorts of kindergarteners enrolled in public and private schools between school years 2001–02 and 2015–16 were analyzed for changes in vaccination trends. The results show an increase in the prevalence and clustering of vaccine exemptions from 2001–02 through 2013–14,...

Using Behavioral Economics to Encourage Parent Behavior Change: Opportunities to Improve Clinical Effectiveness

Sep. 10, 2018

ABSTRACT [FROM JOURNAL]

Pediatric clinical practice often involves improving child health by changing parents' behavior. Strategies from behavioral economics - a field that leverages predictable patterns in human decision-making to overcome barriers to behavior change - can improve health outcomes in adults. Though more research is needed, the application of these approaches to parent behavior change in pediatric settings has the potential to improve the clinical effectiveness of child healthcare. We review the foundational concepts of behavioral economics and identify the unique...

Catherine C. McDonald, Erin Kennedy, Linda Fleisher, and Mark R. Zonfrillo

Abstract [from journal]

Suboptimal compliance with child restraint system (CRS) recommendations can increase risk for injury or death in a motor vehicle crash. The purpose of this study was to examine scenarios associated with incomplete CRS use and non-use in children ages 4⁻10 years. We used a cross-sectional online survey with a convenience sample of parent/caregivers from the United States, age ≥18 years, with a child age 4⁻10 years in their home, who could read and spoke English, and drove child ≥6 times in previous three months. We used descriptive statistics and Mann-

Regional Differences in the Impact of the “Stand Your Ground” Law in Florida

Sep. 5, 2018

Benjamin Ukert, Douglas J. Wiebe, David K. Humphreys

Abstract [from journal]

In October 2005, Florida relaxed restrictions on the use of lethal force in self-defense with the Florida stand your ground law (SYG). We examined whether and how the impact of the Florida SYG varied based on the demographic and economic conditions of each of its counties. Using data from the Florida Universal Crime Reports on homicides and firearm homicides from 1999 to 2014, we found that the impact differed significantly by county urbanization, unemployment, and pre-law homicide rates. The largest increases in homicide and firearm homicide occurred

Association of Hospital Participation in a Medicare Bundled Payment Program With Volume and Case Mix of Lower Extremity Joint Replacement Episodes

Sep. 5, 2018

Abstract [from journal]

Importance: Medicare’s Bundled Payments for Care Improvement (BPCI) initiative for lower extremity joint replacement (LEJR) surgery has been associated with a reduction in episode spending and stable-to-improved quality. However, BPCI may create unintended effects by prompting participating hospitals to increase the overall volume of episodes paid for by Medicare, which could potentially eliminate program-related savings or prompt them to shift case mix to lower-risk patients.

Objective: To evaluate...

Mergers and Marginal Costs: New Evidence on Hospital Buyer Power

Aug. 21, 2018

Abstract [from journal]

We estimate the effects of horizontal mergers on marginal cost efficiencies – an ubiquitous merger justification – using data containing supply purchase orders from a large sample of US hospitals 2009-2015. The data provide a level of detail that has been difficult to observe previously, and a variety of product categories that allows us to examine economic mechanisms underlying “buyer power.” We find that merger target hospitals save on average $176 thousand (or 1.5 percent) annually, driven by geographically local efficiencies in price negotiations for...
