Despite availability of guidelines for nearly a decade and more recent comparative effectiveness research (CER) evidence, the health care system has been slow to adopt recommended practices. Although pediatric health care providers often cite barriers such as limited time, skill, and resources, a frequently overlooked barrier is the lack of data systems to efficiently and accurately assess guideline implementation and to improve quality of care for childhood obesity. Health information technology (HIT) offers potential for accelerating the adoption of CER evidence regarding childhood obesity screening and management, for establishing treatment benchmarks, and for supporting patients and their clinical teams in care improvement. Incorporation of HIT may be especially effective if augmented by outreach to parents and children.
