Methodologic issues in pediatric outcomes research

Abstract

Clinicians, health services researchers, and third-party payers, among others, are justifiably interested in the outcomes of pediatric medical care and are, therefore, supportive of research in this area. Pediatric populations pose some unique methodologic challenges for health services researchers. To date, however, many of the approaches, models, and techniques used in pediatric outcomes research have been imported uncritically from experience with adult populations. As a result, some of the most interesting and salient aspects of pediatric outcomes research have yet to be fully developed. These include the following: 1) the problems posed by the dynamics of childhood development, 2) an emphasis on health supervision, 3) the need to see children within the context of a family system and to appreciate the interrelatedness of child health domains, 4) the measurement of the effects of interventions that span sectors, and 5) the paucity of available data sources. This article reviews these problematic areas and argues for a broad conceptual definition of pediatric health, a systems approach to assessing outcomes, and increased interdisciplinary collaboration.
