OBJECTIVE: To assess the impact of a Massachusetts Medicaid policy change (the Children's Behavioral Health Initiative; CBHI, which required and reimbursed behavioral health [BH] screening with standardized tools at well child visits and developed intensive home- and community-based BH services) on primary care practice examining the relationship of BH screening to subsequent BH service utilization. STUDY DESIGN: Using a repeated cross-sectional design, our 2010 and 2012 Medicaid study populations each included 2000 children/adolescents under the age of 21 years. For each year, the population was randomly selected and stratified into 4 age groups, with 500 members selected per group. Two data sources were used: medical records and Medicaid claims. RESULTS: The CBHI had a large impact on formal BH screening and treatment utilization among children/adolescents enrolled in Medicaid. Screening increased substantially (73%: 2010; 74%: 2012) since the baseline/premandate period (2007) when only 4% of well child visits included a formal screen. BH utilization increased among those formally screened but decreased among those with informal assessments. CONCLUSIONS: CBHI implementation transformed the relationship between primary care and BH services. Changes in regulation and payment resulted in widespread BH screening in Massachusetts primary care practices caring for children/adolescents on Medicaid.

OBJECTIVE: To determine whether the medical-legal advocacy screening questionnaire (MASQ), a simple 10-item questionnaire, is able to screen families in a primary care setting for possible referral to legal services more effectively than the clinical interview alone. METHODS: Family Advocates of Central Massachusetts (FACM) is a medical-legal collaboration that assists low-income families with legal issues that affect child health. A convenience sample of parents seen at each of 5 medical practices associated with FACM was recruited to complete the MASQ prior to a routine child health care visit. Physicians blinded to the result assessed family need for referral to FACM after their usual clinical encounter. The sensitivity and specificity of both the MASQ and provider assessment were calculated. RESULTS: Two hundred fifty-five parents from 5 practices participated in the study. The MASQ identified 85 patients in need of legal services. Prior to reviewing the MASQ, the primary care providers identified 35 families in need of referral to the FACM. After completion of both the MASQ and the medical encounter, 37 families agreed to referral. The MASQ had sensitivity of 0.81 and specificity of 0.75 in predicting program referral. Provider assessment had sensitivity of 0.65 and specificity of 0.95 of predicting program referral. CONCLUSIONS: Routine use of the MASQ would likely identify more patients in pediatric practices who would accept referral to legal assistance than reliance on provider impression alone after a routine clinical encounter.
