Project Overview +

The goal of this study is to understand how older and emerging-older adult patients and their physicians perceive shared decision-making (SDM), and how SDM, as perceived by patients, impacts adherence to recommended colorectal cancer screening.

Aims +

Aim 1. Develop definitions of SDM from the perspectives of older adult patients, emerging-older adult patients, and primary care physicians.

Aim 2. Determine whether the occurrence of patient-defined SDM is associated with adherence to physician- recommended colorectal cancer screening.

Participants +

Patients and primary care physicians from the Virginia Commonwealth University Health System and audio-recordings of patient health examinations at the Henry Ford Health System. 

Intervention +

  • Each patient and physician participates in an individual semi-structured interview lasting approximately 45 to 60 minutes.
  • Patient interviews consists of: having the patient recall a discussion about colorectal cancer screening, indicate how the decision was made using the modified Control Preferences Scale, and explain what happened during the visit to cause the perception.
  • Physicians are asked to: recall a recent colorectal cancer screening discussion with a patient, indicate perceptions of how the screening decision was made, discuss why the decision was perceived in this way, and share if and how they try to foster SDM and how they think patients perceive SDM.
  • Data from coded transcriptions of audio recordings of health examinations at the Henry Ford Health System are used to model the relationship between patient-defined SDM and colorectal cancer screening.
