Impact of a rural preventive care outreach program on children's health.

A "treatment-control" research design incorporating a modified "tracer disease" methodology for measuring health outcomes has been applied to the evaluation of a rural pediatric outreach preventive health care program in Appalachia. The primary research objective was to assess the general level of effectiveness of the health services provided by the program in preventing and/or reducing illness due to common childhood diseases among children receiving these services, when compared to similar (i.e., "matched") children receiving standard pediatric outpatient care but without such outreach services. The research findings indicate that prevalence rates for the selected tracer diseases were generally comparable among program children and their controls. However, evidence of effective identification and treatment of an increased prevalence of iron deficiency anemia by the program was demonstrated. Comparison of the program and control children on their sociocultural characteristics also suggests that the comparable health outcomes for the two groups may have been achieved in the case of the program children despite their somewhat disadvantaged socioeconomic and environmental circumstances relative to the controls; and apparently with lower outpatient services utilization and lower overall costs.
