Hospital-Based Pediatric Quality Improvement Interventions and Health Disparities: A Scoping Review of the Literature

Quality improvement (QI) has the potential to reduce health disparities through multiple mechanisms, including by standardizing care and addressing social barriers to health. National organizations require that hospital systems integrate equity into quality efforts, but effective approaches remain unclear. We aimed to examine the association of hospital-based pediatric QI interventions and racial and ethnic, language, and socioeconomic disparities in health outcomes.

Quantitative studies from January 1, 2000 to December 11, 2023 reporting the effects of pediatric hospital-based QI were selected from PubMed and Embase. Studies were excluded if outcomes were not stratified by race and ethnicity, language, or socioeconomic status. Studies were reviewed in duplicate for inclusion and by 1 author for data extraction.

A total of 22 studies were included. Most studies (n = 19, 86%) revealed preexisting disparities, and 68% of those (n = 13) found disparities reductions post-intervention. Studies with disparity-focused objectives or interventions more commonly found reduced disparities than studies of general QI (85% vs 33%). Hospital-based process standardization was associated with reduced disparities in provider practices. Most interventions associated with reduced disparities in patient-facing outcomes involved community/ambulatory partnership. Limitations included potential exclusion of relevant studies, topic heterogenity, and risk of bias.

Although the authors of few published hospital-based QI initiatives assessed their equity effect, intentionally designed QI studies were associated with reduced disparities. Interventions focused on care standardization may reduce disparities in care quality, although multilevel interventions are likely needed to affect the health care structures that influence more significant patient outcomes.
