Patients' Journey to Medication Adherence (2018-2019)

Background

In the U.S., about half of the 3.2 billion prescriptions dispensed annually are not taken as instructed, leading to 125,000 preventable deaths and wasted medical expenditure amounting to $290 billion a year.

Medication nonadherence is a prevalent issue worldwide and across all socioeconomic groups, yet existing intervention programs have been only moderately effective, and long-term results are often less than satisfactory. Improving patient adherence is critical in raising healthcare quality, leveling health disparities and containing costs for the individuals and the health system. The issue requires more public attention and further research to understand and target the motivators and barriers influencing people’s decisions and actions.

Project Description

This Bass Connections project aims to provide richer insights into patient psychology and cognition, in order to help bridge the gaps in clinical research for more optimal medication adherence and improved health outcomes.

The project has three focus areas: 

  • Uncovering patients’ insights and thought processes regarding illness, treatment and relationship with physicians. The team will investigate how patients cope with the externalities of having to manage a prescribed regimen, their involvement in shared decision-making and attitudes about nonadherence, such as self-rationalization, frustration and desired autonomy.
  • Examining health equity and cultural differences in self-perceptions and value of medication. Qualitative results gathered during the 2017-18 project will help shape a large scale international comparative study—one survey will be conducted in the U.S. with a parallel survey in Asia.
  • Implementing a longitudinal study to capture the fluctuations of patients’ feelings and behavior related to medication and how these factors influence adherence over time.

The results will help strengthen identification tools for noncompliance risk screening and in designing future intervention programs, providing evidence and recommendations for medical professionals, policymakers and researchers as well as health-related industries.

Anticipated Outcomes

Preliminary results used for grant proposals; study findings disseminated through group-authored conference presentation(s) and peer-reviewed publication(s)

Student Opportunities

In addition to regular group meetings and discussions, faculty and graduate student(s) will provide individual mentoring sessions. Student team members are encouraged to develop sub-projects of their interest (individually or in pairs) and take turns leading discussions and tasks. Faculty will help identify opportunities for conference presentations and journal submissions for the team.

Students will gain valuable experience involved in many stages of research: from literature review (utilizing PubMed and EndNote), formulating research questions, developing screener and designing survey, IRB procedure, collecting and analyzing both qualitative and quantitative data (learning NVivo/Atlas and SAS/SPSS), to interpreting findings and writing manuscripts. They will work collaboratively and independently on different elements to practice management/leadership and teamwork skills.

Field experts and executives from the relevant industries and public agencies will be invited to share their knowledge and contribute to the multifaceted learning of the team, affording unique professional networking opportunities for the students. The team will also discuss policy implications regarding healthcare quality, insurance payment system, pharmaceutical innovation and pricing as well as government welfare models.

Students may pursue opportunities to travel in the summer (potentially with the support of DukeEngage) to investigate the impacts of healthcare systems and policies on patient behavior and medication outcome around the U.S. or abroad.

The team will likely be comprised of 3-4 undergraduates and 2 graduate students or postdocs (may include but not limited to pre-health, public policy, economics, psychology, sociology, global health, nursing, business, medicine, statistics). Ph.D. students with strong research experience are welcome to apply and serve as project manager to help coordinate research logistics as well as assisting mentoring undergraduates. Postdocs, third-year medical students and staff statisticians are welcome to join the team, too.

Cross-level and peer evaluations will be performed periodically to ensure group learning and project progress. Students will be evaluated on their initiatives, acquisition and application of research skills, efforts and commitment to teamwork and contribution to collective learning.

Duke undergraduates and graduate students can apply for this project team beginning on January 24. The priority deadline is February 16 at 5:00 p.m.

Timing

Summer 2018 – Summer 2019  

  • Summer 2018: (off campus) Continuing students are encouraged to revise their individual papers or collaborate on the team paper to get ready for journal submission; may elect to do an internship domestically or overseas to shadow and investigate the impacts of healthcare system and policies on medical practice and patient behavior (faculty will help identify sponsor organizations and local mentors). New students will start background research and literature review; complete online IRB training modules.
  • Fall 2018: Team building, group training on research methodology and data analysis software; continue literature review; mini lectures by invited field experts (throughout the year); collectively design participant screener, interview discussion guide and survey; complete IRB proposal; start longitudinal studies; first stage of data analysis and drafting manuscript; on campus or conference presentation of preliminary findings
  • Spring 2019: Continue longitudinal study; conduct international study, compare results; second stage of data analysis; collaboratively write manuscript; external grant proposal
  • Summer 2019: Manuscript revision for journal submission; students may travel domestically or overseas to examine the effects of care delivery models and public policies on health outcomes (optional with support from DukeEngage or other funding)
