title: Inconsistencies in patient perceptions and observer ratings of shared decision making: the case of colorectal cancer screening.
abstract: OBJECTIVE
  To compare patient-reported and observer-rated shared decision making (SDM) use for colorectal cancer (CRC) screening and evaluate patient, physician and patient-reported relational communication factors associated with patient-reported use of shared CRC screening decisions.
  
  
  METHODS
  Study physicians are salaried primary care providers. Patients are insured, aged 50-80 and due for CRC screening. Audio-recordings from 363 primary care visits were observer-coded for elements of SDM. A post-visit patient survey assessed patient-reported decision-making processes and relational communication during visit. Association of patient-reported SDM with observer-rated elements of SDM, as well as patient, physician and relational communication factors were evaluated using generalized estimating equations.
  
  
  RESULTS
  70% of patients preferred SDM for preventive health decisions, 47% of patients reported use of a SDM process, and only one of the screening discussions included all four elements of SDM per observer ratings. Patient report of SDM use was not associated with observer-rated elements of SDM, but was significantly associated with female physician gender and patient-reported relational communication.
  
  
  CONCLUSIONS
  Inconsistencies exist between patient reports and observer ratings of SDM for CRC screening.
  
  
  CONCLUSIONS
  Future studies are needed to understand whether SDM that is patient-reported, observer-rated or both are associated with informed and value-concordant CRC screening decisions.
