he Centers for Disease Control and Prevention 1 estimates that a quarter of adults in the United States report having a mental illness at any given time and about half will experience mental illness during their lifetime. In the wake of the Connecticut school shooting and other recent mass shootings, policy makers and the public have called for increased access to mental health services. 2 For example, President Obama's "Now Is the Time" proposal, released in January 2013, called for better mental health services, including programs to identify diagnosable mental health problems early so that patients can be referred for treatment, and increased training of mental health professionals. 2 Psychiatrists play an important role in the diagnosis and treatment of patients with mental illnesses particularly because of their training and ability to prescribe medications. 3 One issue that advocates for increased mental health access have neglected to explore is limited access owing to psychiatrists' refusal to accept insurance. 4 In previous studies, we and others have shown that overall physician acceptance rates for private noncapitated insurance was high but declining modestly in recent years. [5][6][7] Little is known about specialty differences in insurance acceptance rates, but prior reports suggest that nonacceptance of insurance may be particularly high for psychiatrists.IMPORTANCE There have been recent calls for increased access to mental health services, but access may be limited owing to psychiatrist refusal to accept insurance.OBJECTIVE To describe recent trends in acceptance of insurance by psychiatrists compared with physicians in other specialties.
DESIGN, SETTING, AND PARTICIPANTSWe used data from a national survey of office-based physicians in the United States to calculate rates of acceptance of private noncapitated insurance, Medicare, and Medicaid by psychiatrists vs physicians in other specialties and to compare characteristics of psychiatrists who accepted insurance and those who did not.
MAIN OUTCOMES AND MEASURESOur main outcome variables were physician acceptance of new patients with private noncapitated insurance, Medicare, or Medicaid. Our main independent variables were physician specialty and year groupings
