Association of insurance gains and losses with access to prescription drugs.
The researchers used longitudinal data to assess the effects of insurance gains and losses on prescription drug access. Their findings that unmet need for prescription drugs declined among initially uninsured adults who gained coverage and doubled among initially insured adults who lost coverage provide longitudinal evidence that having and maintaining health insurance is a key protection against unmet need for prescription drugs in a nationally representative sample.

Estimating the effect of health insurance on personal prescription drug importation.
Personal prescription drug importation occurs in the United States because of the high cost of U.S. medicines and lower cost of foreign equivalents. The investigators used inverse probability weighted marginal structural models and data on 87,494 individuals from the 2011-2013 National Health Interview Survey to estimate the marginal association between no health insurance and importation within U.S. subpopulations.

Impact of a value-based formulary in three chronic disease cohorts.
This study assessed the impact of a value based formulary (VBF) on medication adherence and patient and health plan expenditures on 3 chronic disease states: diabetes, hypertension, and hyperlipidemia. The investigators measured medication expenditures from member, health plan, and member-plus-health plan (overall) perspectives and medication adherence as proportion of days covered. They conducted an exploratory analysis of medication utilization classifying medications according to whether co-payments moved up or down in the year following VBF implementation.
