Medical and psychiatric conditions of alcohol and drug treatment patients in an HMO: comparison with matched controls.

BACKGROUND: Substance abuse and health problems seem to be inextricably related. Yet, prior research on the health conditions related to substance abuse is largely focused on alcohol and is from patients treated in publicly funded programs, inpatients, and the general population. METHODS: This study compares the prevalence of medical and psychiatric conditions among 747 substance abuse patients and 3690 demographically matched controls from the same health maintenance organization, and examines whether any heightened prevalence for substance abuse patients (relative to controls) varies according to demographic subgroups and type of substance. RESULTS: Approximately one third of the conditions examined were more common among substance abuse patients than among matched controls, and many of these conditions were among the most costly. We also found that pain-related diagnoses, including arthritis, headache, and lower back pain, were more prevalent among such patients, particularly those dependent on narcotic analgesics. CONCLUSIONS: Our findings point to the importance of examining comorbid medical conditions and substance abuse in both primary and specialty care. Our findings regarding pain-related diagnoses among patients dependent on narcotic analgesics highlight the need for linkages between primary care and substance abuse treatment. Moreover, optimal treatment of many common medical disorders may require identification, intervention, and treatment of an underlying substance abuse disorder.

Services integration and cost-effectiveness.

Alcohol treatment services are increasingly combined with other health and social services to address the needs of multiple-problem clients. Hence, it has been of growing policy interest to find the most effective and the most cost-effective ways of linking these services. This symposium presents some recent studies in this area. The small but growing body of studies in this area has great potential to inform public policy debates.

Utilization and cost impact of integrating substance abuse treatment and primary care.

OBJECTIVE: To examine the impact of integrating medical and substance abuse treatment on health care utilization and cost. RESEARCH DESIGN: Randomized clinical trial assigning patients to one of two treatment modalities: an Integrated Care model where primary health care is provided along with substance abuse treatment within the unit and an Independent Care model where medical care is provided in the HMO's primary care clinics independently from substance abuse treatment. SUBJECTS: Adult patients entering treatment at the outpatient Chemical Dependency Recovery Program in Kaiser Sacramento. MEASURES: Medical utilization and cost for 12 months pretreatment and 12 months after treatment entry. RESULTS: For the full, randomized cohort, there were no statistically significant differences between the two treatment groups over time. However, among the subset of patients with substance abuse related medical conditions (SAMC), Integrated Care patients had significant decreases in hospitalization rates (P = 0.04), inpatient days (P = 0.05) and ER use (P = 0.02). Total medical costs per member-month declined from 431.12 US dollars to 200.03 US dollars (P = 0.02). Among SAMC Independent Care patients, there was a downward trend in inpatient days (P = 0.08) and ER costs (P = 0.05) but no statistically significant decrease in total medical cost. CONCLUSIONS: (Non)findings for the full sample suggest that integrating substance abuse treatment with primary care, may not be necessary or appropriate for all patients. However, it may be beneficial to refer patients with substance abuse related medical conditions to a provider also trained in addiction medicine. There appear to be large cost impacts of providing integrated care for such patients.

Medicaid patients in a private health maintenance organization: patterns of chemical dependency treatment.

Although many Medicaid beneficiaries receive health care through commercial health maintenance organizations (HMOs), the impact of private managed care on low-income individuals seeking treatment for substance abuse has rarely been studied. This study examined treatment patterns of 234 Medicaid recipients who presented for care at an HMO between 1995 and 1997. After adjustment for demographic factors and duration of health plan membership, the Medicaid patients returned to start treatment after intake less often (odds ratio = 0.60) and dropped out of treatment sooner (median = 14 versus 28 days) than non-Medicaid patients. While many Medicaid patients received significant amounts of substance abuse treatment, further research is needed to explain the observed treatment gap and to identify areas where HMOs can improve services for some of their most vulnerable members.
