# The ROUTT-B (Reduce Over-Utilized Tests and Treatments in Bronchiolitis) Study: Developing a Roadmap for De-Implementation

## Abstract

PROJECT SUMMARY
The overarching goal of this proposal is to use bronchiolitis as a case study to advance the science of de-
implementation by identifying strategies and processes for reducing over-testing and over-treatment in
bronchiolitis that can later be broadly adapted to varied contexts and disease processes. The challenge in
bronchiolitis is that providing high-quality, evidenced-based care requires a “less is more” approach as the non-
recommended, outdated, and potentially harmful tests and treatments that most admitted patients receive do
not have replacements. Therefore, bronchiolitis which is the most common cause of hospitalization among
infants, is an ideal condition to study de-implementation.
 In her set of projects, Dr. Tyler proposes the innovative application of dissemination and
implementation (D&I) science to the unique problem of de-implementation. Within a learning health system
called PEDSnet, Dr. Tyler will use the PRISM D&I model as a guide to: 1) use qualitative methods to define
contextual factors influencing over-utilization in bronchiolitis from the perspective of healthcare providers,
parents, and healthcare organizations, 2) develop a set of pragmatic, feasible, and effective de-implementation
strategies for bronchiolitis that includes guidance on how to adapt the strategies to local contexts, and 3)
conduct a pilot study to determine the feasibility, acceptability, and de-implementation effectiveness of the de-
implementation strategies. As one of the first explorations of contextual factors fostering overuse or enabling
successful de-implementation, this study is expected to generate valuable knowledge relevant to de-
implementation across diseases and healthcare settings. The results will provide pilot data for a large-scale,
pragmatic, randomized-controlled trial of the de-implementation strategies so that ineffective and potentially
harmful medical practices are reduced.
 The applicant, Amy Tyler, MD, MSCS is excellently prepared to complete the proposed research, given
her past training and experience. To build upon this experience and progress toward her long-term career
goals, Dr. Tyler seeks to use this career development award to achieve investigative independence and
advance scientific understanding of effective and generalizable methods for de-implementing potentially
harmful tests and treatments. This work will promote guideline concordant, high quality, acute care for pediatric
patients, an AHRQ priority population. Dr. Tyler has assembled an internationally-recognized mentorship team
with expertise directly related to her training goals in dissemination and implementation science (D&I) (Drs.
Dempsey and Glasgow), qualitative research (Drs. Dempsey and Holtrop), and pragmatic clinical trials (Drs.
Dempsey and Glasgow). She will conduct the proposed research in the collaborative environment of the
University of Colorado Anschutz Medical Campus supported by the Adult and Child Consortium for Health
