OBJECTIVES. The purpose of this study was to develop a model, using the epidemiologic tool of attributable risk, for estimating the cost of substance abuse to Medicaid. METHODS. Based on prior substance-use and morbidity research, population attributable risks for substance abuse-related diseases were calculated. (These risks measure the proportion of total disease cases attributable to smoking, drinking, and drug use.) The risks for each disease were applied to Medicaid hospital discharges and days on the 1991 National Hospital Discharge Survey that had these diseases as primary diagnoses. The cost of these substance abuse-related days were added to Medicaid hospital costs for direct treatment of substance abuse. RESULTS. More than 60 medical conditions involving 1100 diagnoses were identified, at least in part, as attributable to substance abuse. Factoring these substance abuse-related conditions into hospital costs, 1 out of 5 Medicaid hospital days, or 4 million days, were spent on substance abuse-related care in 1991. In 1994, this would account for almost $8 billion in Medicaid expenditures. CONCLUSIONS. The use of tobacco, alcohol, and drugs contributes significantly to hospital costs. To address rising costs, substance abuse treatment and prevention should be an integral part of any health care reform effort.

ABSTRACT:The New Jersey Individual Health Coverage Program (IHCP) was implemented in 1993; key provisions included pure community rating and guaranteed issue/renewal of coverage. Despite positive early evaluations, the IHCP appears to be heading for collapse. Using unique administrative and survey data, we examined trends in IHCP enrollment and premiums. We found the stability of the IHCP to be fragile in light of improving opportunities for job-related health insurance. We also found that it is retaining high-risk enrollees. Institutional realities and the difficulty of identifying a control group preclude attributing causality to the plan's pure community rating and open enrollment provisions.

This study assesses trends in telehealth use in Maine-a rural state with comprehensive telehealth policies-across payers, services, and rurality, and identifies barriers and facilitators to the adoption and use of telehealth services.Methods: Using a mixed-methods approach, researchers analyzed data from Maine's All Payer Claims Database (2008Database ( -2016 and key informant interviews with health care organization leaders to examine telehealth use and explore factors impacting telehealth adoption and implementation.Findings: Despite a 14-fold increase in the use of telehealth over the 9-year study period, use remains low-0.28% of individuals used telehealth services in 2016 compared with 0.02% in 2008. Services provided via telehealth varied by rurality; speech language pathology (SLP) was the most common type of service among rural residents, while psychiatric services were most common among urban residents. Medicaid was the primary payer for over 70% of telehealth claims in both rural and urban areas of the state, driving the increase of telehealth claims over time. Issues challenging organizations seeking to deploy telehealth included provider resistance, staff turnover, provider shortages, and lack of broadband. Key informants identified inadequate and inconsistent reimbursement as barriers to comprehensive, systematic billing for telehealth services, resulting in underrepresentation of telehealth services in claims data. Conclusions:Claims covered by Medicaid account for much of the observed expansion of telehealth use in Maine. Telehealth appears to be improving access to behavioral health and SLP services. Provider shortages, broadband, and Medicare and commercial coverage policies limit the use of telehealth services in rural areas.
