A child health assessment and screening program, staffed by volunteers, has evaluated approximately 5,000 children in a general pediatric clinic. A sample of 500 children was studied to determine characteristics of the population served, quality of the work of the volunteers and the number of new problems identified. Use of well-trained volunteers, provided with adequate supervision and follow-up physical examination of the children, identified many new problems at minimal cost and proved an effective means of expanding quality health care.
