Problem: Obstetrician-gynecologists are the principal health care providers for women during pregnancy and the perinatal period. The Collaborative Ambulatory Research Network (CARN) project assesses the clinical care patterns and educational needs of health care providers to women in order to support efforts to improve health care for mothers and their children. Study findings are disseminated within ACOG to inform the College's educational efforts, and are published in peer reviewed journals. Goals and Objectives: The goals of the CARN project are: 1) Assess the opinions, knowledge, clinical practice, and educational needs of physicians regarding areas of clinical medicine relevant to maternal and child health. 2) Assess the efficacy of ACOG clinical practice guidelines. 3) Inform and support ACOG educational efforts. 4) Disseminate results of the CARN studies to as broad an audience as possible. 5) Monitor the training, recruitment, and retention of health care professionals into maternal and child health, especially under-represented minorities. 6) Assess patient perceptions of care provided by physicians 7) Encourage interaction among different health care professionals, researchers, and policy analysts to study critical issues in maternal and child health. 8) Train and mentor students and young researchers. Methodology: The CARN is the only existing national collective of practicing obstetrician-gynecologists who have been recruited to participate in survey studies. CARN study questionnaires are designed to generate descriptive data pertaining to: obstetrician-gynecologists' practice patterns, clinical experiences, basic knowledge, professional training, access to resource materials, and educational needs. CARN studies are often developed in conjunction with the production or revision of ACOG clinical practice guidelines in order to assess the extent to which ACOG Fellows are aware of and following recommended best practices. The CARN project also supports workshops and symposia, production of review articles, and the training of students. Coordination: Survey studies are constructed with consultation with ACOG Fellows, the Child and Maternal Health Branch of HRSA, other federal agencies, and US universities and research institutions. CARN-sponsored workshops are another means by which the CARN project interacts and coordinates with the broader community of maternal and child health researchers and policy makers. Evaluation: The results from survey studies are published in peer reviewed journals. Periodically, review articles outlining the important findings of multiple CARN studies are produced. This serves the purpose of disseminating the information regarding current practice patterns in obstetrics and gynecology as widely as possible among obstetrician-gynecologists and health care policy researchers and decision makers. Annotation: The Collaborative Ambulatory Research Network (CARN) assesses the clinical care patterns and educational needs of health care providers by conducting studies on a wide range of critical topics related to women's health. The results of CARN studies inform health care providers and medical education efforts.
