Identification and treatment of mental and substance use conditions - Health plans strategies

Background: Mental health and substance use conditions are under-recognized and under-treated. Private health plans may be able to affect the extent of screening and, thus, identification of enrollees who need treatment. Objectives: The goals of this study were to determine strategies used by health plans to identify mental health and substance use conditions; and describe the characteristics of health plans associated with use of these strategies. Methods: In 2003, we conducted a nationally representative survey of private health plans regarding behavioral health services. A total of 368 health plans (83% response rate) provided information about their managed care products: health maintenance organization (HMO), point-of-service (POS), or preferred provider organization (PPO) products (812 in total). Measures: We asked whether plans verify primary care providers' screening for mental health or substance use conditions, screen outside of primary care, and distribute practice guidelines. We characterized each product in terms of "carve-out" to a specialty behavioral health vendor, tax status, and region and market area population. Results: Thirty-four percent of products verify primary care providers' screening for mental health, but only 8% verify alcohol or drug screening. Outside of primary care, 31% conduct screening through the mail, phone, or internet. Depression guidelines are distributed to primary care providers by 78% of managed care products: alcohol or drug guidelines are distributed by 33%. In multivariate analyses, specialty contracting was positively associated, and PPO product type was negatively associated with these strategies. Conclusions: Most health plans use multiple strategies to improve identification of behavioral health conditions, but use of such strategies was greater for mental health than for substance use conditions.
