Abstract
OBJECTIVES: To investigate and compare the extent of shared decision making (SDM) in orthodontics from the perspective of patients, clinicians and independent observers. DESIGN: A cross-sectional, observational study. SETTING: NHS teaching hospital. PARTICIPANTS: A total of 31 adult patients and their treating clinicians were included in the study. METHODS: The extent of SDM in new patient orthodontic consultations was measured using three versions of a validated instrument: the self-administered patient dyadic-OPTION scale; the self-administered clinician dyadic-OPTION scale; and an independent observer-rated OPTION12 scale. Patients and clinicians completed the 12-item dyadic-OPTION questionnaire independently at the end of the consultation to rate their perceived levels of SDM. The consultations were also audio-recorded and two calibrated raters independently rated the extent of SDM in these consultations using the OPTION12 scale. RESULTS: There was excellent inter-rater reliability between the two independent raters using the OPTION12 scale (intraclass correlation coefficient (ICC) = 0.909). The mean patient, clinician and independent observer OPTION scores for SDM were 90.4% (SD 9.1%, range 70.8% to 100%), 76.2% (SD 8.95%, range 62.5% to 95.8%) and 42.6% (SD 17.4%, range 13.5% to 68.8%), respectively. There was no significant correlation between the OPTION scores for the three groups (ICC = -0.323). CONCLUSIONS: The results showed that generally high levels of SDM were perceived by patients and clinicians but lower levels of SDM were scored by the independent observers. However, it could be argued that the patient's perception of SDM is the most important measure as it is their care that is affected by their involvement.
