Designed to help social service agencies achieve a comprehensive system of care for chemically dependent pregnant and postpartum women and their drug-exposed children, the model described in this report was developed by a panel of 12 experts in the field of perinatal addiction and drug exposure in infants. The report begins with an overview of general issues central to the discussion of a model of care, and then addresses 10 major themes applicable to all service areas. These themes include coordination of services, staff training and support, cultural sensitivity, access to services, and research needs. A narrative description of the proposed model of care is then presented. The description focuses on five categories: (1) prevention and health education; (2) outreach; (3) health and psychosocial screening and assessment; (4) direct services, including health care, social services, alcohol and drug treatment and recovery services, specific services for drug-exposed children, and services for partners and family members; and (5) case management. Seven appendices make up the greater part of this report. They include: a list of panel participants; a blank and completed matrix describing stages of service delivery, from prepregnancy to 3 years postnatal; descriptions of special populations, including women and children with HIV, and women in jails; a checklist of services; assessment instruments; and a glossary of terms.
