Treatment Adherence Research

Treatment Adherence Research - CPCEDigital health strategies, such as eHealth and social media, offer multiple platforms to actively engage families in discussion and activities with one another and the clinical team.  CPCE's treatment adherence research studies both these applications to determine their potential to increase patient treatment adherence, as well as their potential to cause harm from data shared in social media.

Currently, the research aims to:

  • better understand patient medication use and side effects

  • integrate mobile applications and software with pediatric practice

  • bring high-risk families together to provide mutual support

  • achieve valuable and measurable health outcomes

We are using a range of methods, including qualitative, informatics, and natural language processing (or text mining), as well as clinical trials.

Asthma Treatment Adherence

For this project, we study the patterns of use of controller medications for children with high risk, urban asthma in order to implement timely interventions that target the causes of lapsed patterns of controller medication use.  

Prior studies estimate average rates of adherence with prescribed controller regimens to be approximately 50 percent. Rates are lower in urban minority children, but average rates don’t provide information on how children take their medication over time and when and why these behaviors may change.  

Using electronic medication monitoring and group-based modeling, we mapped trajectories of medication use over time to find common patterns. We found distinct patterns of medication use (lapsed, periodic, sustained) among children with the highest ED and hospital use in a local Medicaid managed care population. In a feasibility study, asthma control scores improved over 3 months of an intervention involving outreach by a community health worker that was triggered by electronic adherence alerts.   

A follow-up study is underway evaluating adherence to controller medications in the months following asthma hospitalization and the efficacy of text-messaging based reminder system in enhancing adherence.

What’s Next in Treatment Adherence Research

CPCE researchers have the following active research projects underway:

iAPP: integrating Apps in Pediatric Practice -- Researchers are developing a process to integrate evidence-based and clinically evaluated health apps for families into pediatric care at CHOP in order to improve patient outcomes.

Grow2Gether – Researchers are developing a peer-based social media intervention to promote healthy growth from infancy.

Mining The Twittersphere -- Researchers are using crowdsourcing techniques on Twitter to solicit and find information about pediatric medication side effects.

Funding: CHOP Healthy Weight Program, CHOP Department of Pediatrics, Leonard Davis Institute at University of Pennsylvania

Please contact Alexander Fiks, MD, MSCE, CPCE associate director, associate medical director of the Pediatric Research Consortium, and an Urban Care pediatrician at CHOP, for more information about these research projects.
