Objective: Examine how patient-clinician information engagement (PCIE) may operate through feeling informed to influence patients' treatment decision satisfaction (TDS).
Methods: Randomly drawn sample (N=2013) from Pennsylvania Cancer Registry, comprised of breast, prostate and colon cancer patients completed mail surveys in the Fall of 2006 (response rate=64%) and Fall of 2007. Of 2013 baseline respondents, 85% agreed to participate in follow-up survey (N=1703). Of those who agreed, 76% (N=1293) completed follow-up surveys. The sample was split between males and females. The majority of participants were White, over the age of 50, married, and with a high school degree. Most reported having been diagnosed with in situ and local cancer.
Results: PCIE was related to concurrent TDS (beta=.06) and feeling informed (beta=.15), after confounder adjustments. A mediation analysis was consistent with PCIE affecting TDS through feeling informed. Baseline PCIE predicted feeling informed (beta=.04) measured 1 year later, after adjustments for baseline feeling informed and other confounders. Feeling informed was related to concurrent TDS (beta=.35) after confounder adjustment and follow-up TDS (beta=.13) after baseline TDS and confounder adjustment.
Conclusion: Results suggest PCIE affects TDS in part through patients' feeling informed.
Practice implications: PCIE may be important in determining patients' level of feeling informed and TDS.
