Elimination of the Out-of-Pocket Charge for Children's Primary Care Visits: An Application of Value-Based Insurance Design.

OBJECTIVE: To evaluate the impact of a value-based insurance design for primary care among children. STUDY DESIGN: A retrospective analysis of health care claims data on 25 950 children (<18 years of age) was conducted. Individuals were enrolled in a large employer's health plans when zero out-of-pocket cost for primary care physician visits was implemented. A rigorous propensity score matching process was used to generate a control group of equal size from a database of other employer-sponsored insurees. Multivariate difference-in-differences models estimated the effect of zero out-of-pocket cost on 21 health services and cost outcomes 24 months after intervention. RESULTS: Zero out-of-pocket cost for primary care was associated with significant increases (P < .01) in primary care physician visits (+32 per 100 children), as well as decreases in emergency department (-5 per 100 children) and specialist physician visits (-12 per 100 children). The number of prescription drug fills also declined (-20 per 100 children), yet medication adherence for 3 chronic conditions was unaffected. The receipt of well child visits and 4 recommended vaccinations were all significantly (P < .05) greater under the new plan design feature. Employer costs for primary care increased significantly (P < .01) in association with greater utilization ($29 per child), but specialist visit costs declined (-$12 per child) and total health care costs per child did not exhibit a statistically significant increase. CONCLUSION: This novel application of value-based insurance design warrants broader deployment and assessment of its longer term outcomes. As with recommended preventive services, policymakers should consider exempting primary care from health insurance cost-sharing.

Financial Incentives, Workplace Wellness Program Participation, and Utilization of Health Care Services and Spending.

This paper analyzes data from a large employer that enhanced financial incentives to encourage participation in its workplace wellness programs. It examines, first, the effect of financial incentives on wellness program participation, and second, it estimates the impact of wellness program participation on utilization of health care services and spending. The Patient Protection and Affordable Care Act of 2010 (PPACA) allows employers to provide financial incentives of as much as 30 percent of the total cost of coverage when tied to participation in a wellness program. Participation in health risk assessments (HRAs) increased by 50 percentage points among members of unions that bargained in the incentive, and increased 22 percentage points among non-union employees. Participation in the biometric screening program increased 55 percentage points when financial incentives were provided. Biometric screenings led to an average increase of 0.31 annual prescription drug fills, with related spending higher by $56 per member per year. Otherwise, no significant effects of participation in HRAs or biometric screenings on utilization of health care services and spending were found. The largest increase in medication utilization as a result of biometric screening was for statins, which are widely used to treat high cholesterol. This therapeutic class accounted for one-sixth of the overall increase in prescription drug utilization. Second were antidepressants, followed by ACE inhibitors (for hypertension), and thyroid hormones (for hypothyroidism). Biometric screening also led to significantly higher utilization of biologic response modifiers and immunosuppressants. These specialty medications are used to treat autoimmune diseases, such as rheumatoid arthritis and multiple sclerosis, and are relatively expensive compared with non-specialty medications. The added spending associated with the combined increase in fills of 0.02 was $27 per member per year--about one-half of the overall increase in prescription drug spending from those who participated in biometric screenings.

Consumer-directed health plans reduce the long-term use of outpatient physician visits and prescription drugs.

Consumer-directed health plans (CDHPs) are designed to make employees more cost- and health-conscious by exposing them more directly to the costs of their care, which should lower demand for care and, in turn, control premium growth. These features have made consumer-directed plans increasingly attractive to employers. We explored effects of consumer-directed health plans on health care and preventive care use, using data from two large employers-one that adopted a CDHP in 2007 and another with no CDHP. Our study had mixed results relative to expectations. After four years under the CDHP, there were 0.26 fewer physician office visits per enrollee per year and 0.85 fewer prescriptions filled, but there were 0.018 more emergency department visits. Also, the likelihood of receiving recommended cancer screenings was lower under the CDHP after one year and, even after recovering somewhat, still lower than baseline at the study's conclusion. If CDHPs succeed in getting people to make more cost-sensitive decisions, plan sponsors will have to design plans to incentivize primary care and prevention and educate members about what the plan covers.

Medication utilization and adherence in a health savings account-eligible plan.

OBJECTIVES: To evaluate the impact of a consumerdirected health plan with a health savings account (CDHP-HSA) on utilization of and adherence to medications among individuals with chronic disease. STUDY DESIGN: Pre-post comparison study with matched control group (difference-in-differences analysis). METHODS: Data on workers and dependents with 1 or more of 5 chronic conditions--hypertension, dyslipidemia, diabetes, asthma/chronic obstructive pulmonary disease (COPD), and depression--were obtained from an employer that fully replaced its preferred provider organizations (PPOs) with a CDHP-HSA in 2007. A control group of participants from an employer that maintained its PPO throughout the 3-year study period (2006-2008) was created by matching on preperiod (2006) individual characteristics. Difference-in-differences estimates of the impact of the CDHP-HSA were derived by chronic condition for number of prescriptions, proportion of days covered (PDC), and an indicator for a PDC of 0.80 or higher. RESULTS: During the first year after implementation, enrollees with hypertension, dyslipidemia, and diabetes had significantly less medication utilization (by 1-2 prescriptions) and lower adherence rates (by 0.05-0.09 in PDC; 0.04-0.13 in the proportion adherent). These reductions abated, yet remained, after 2 years among hypertension and dyslipidemia patients. The PDC was significantly lower in patients with depression by 0.07 and 0.05 after 1 and 2 years under the new plan, respectively. No statistically significant impacts were detected on enrollees with asthma/COPD. CONCLUSIONS: A CDHP-HSA full replacement was associated with reduced adherence for 4 of 5 conditions. If this reduced adherence is sustained, it could adversely impact productivity and medical costs.

Sources of health insurance and characteristics of the uninsured: analysis of the March 2012 Current Population Survey.

HEALTH COVERAGE RATE INCREASED, UNINSURED DOWN: The percentage of the nonelderly population (under age 65) with health insurance coverage increased to 82 percent in 2011, notable since increases in health insurance coverage have been recorded in only five years since 1994. EMPLOYMENT-BASED COVERAGE REMAINS DOMINANT SOURCE OF HEALTH COVERAGE, BUT CONTINUES TO ERODE: Employment-based health benefits remain the most common form of health coverage in the United States, though it represents a declining share. In 2011, 58.4 percent of the nonelderly population had employment-based health benefits, down from the peak of 69.3 percent in 2000, during the 1994-2011 period. PUBLIC PROGRAM COVERAGE IS EXPANDING: Public program health coverage expanded as a percentage of the population in 2011, accounting for 22.5 percent of the nonelderly population. Enrollment in Medicaid and the State Children's Health Insurance Program (S-CHIP) also increased to a combined 46.9 million in 2011, covering 17.6 percent of the nonelderly population, significantly above the 10.2 percent level of 1999. INDIVIDUAL COVERAGE STABLE: The percentage represented by individually purchased health coverage was unchanged in 2011 and has basically hovered in the 6-7 percent range since 1994. WHAT TO EXPECT IN 2012: The unemployment rate in 2012 has been about 8 percent since the beginning of the year, and remains high amidst a still-sluggish economy. As a result, the nation is likely to see a corresponding erosion of employment-based health benefits when the data for 2012 are released next year. Until the economy gains enough strength to have a substantial impact on the labor market, a rebound in employment-based coverage is unlikely.

Private health insurance exchanges and defined contribution health plans: is it déjà vu all over again?

This issue brief examines issues related to private health insurance exchanges, possible structures of an exchange, funding, as well as the pros, cons, and uncertainties to employers of adopting them. A summary of recent surveys on employer attitudes are examined, as are some changes that employers have made to other benefits that might serve as historical precedents for a move to some type of defined contribution health benefits approach.
