Measuring the "triple aim" in transition care: a systematic review.

BACKGROUND AND OBJECTIVES Without adequate support, adolescents transitioning from the pediatric to the adult health care system are at increased risk for poor health outcomes. Numerous interventions attempt to improve this transition, yet few comprehensively evaluate efficacy. To advance evaluation methods and ultimately the quality of transition services, it is necessary to understand the current state of health care transition measurement. This study examines and categorizes transition measures by using the "Triple Aim" framework of experience of care, population health, and cost of care. METHODS Ovid Medline and the Cumulative Index to Nursing and Allied Health Literature were searched for articles published between 1995 and 2013. Two reviewers independently screened studies and included those that evaluated the impact of a health care transition intervention. Measures were subsequently classified according to population health, experience of care, and costs of care. RESULTS Of the 2282 studies initially identified, 33 met inclusion criteria. Population health measures were used in 27 studies, with disease-specific measures collected most frequently. Fifteen studies measured cost, most often service utilization. Eight studies measured experience of care, with satisfaction assessed most commonly. Only 3 studies examined all 3 domains of the "Triple Aim." Transition interventions described in the gray literature were not reviewed. CONCLUSIONS Transition programs are inconsistently evaluated in terms of their impact on population health, patient experience, and cost. To demonstrate improvement in the transition from pediatric to adult health care, a more robust and consistent set of measures is needed.
