Shared-Decision-Making Experiences in Breast Cancer Care with and without Patient Participation in Multidisciplinary Tumor Conferences: A Mixed-Methods-Study.

PURPOSE

This study aimed (1) to analyze patients' perceived shared decision-making (SDM) experiences over 4 weeks between patients participating or not in multidisciplinary tumor conferences (MTCs) and (2) to analyze the association of patients' active participation in and organizational variables of MTCs with patients' perceived SDM experience directly after MTC.

PATIENTS AND METHODS

From the N=317 patients, this observational study included patient surveys, observations, and audio transcripts from MTCs with (N=82) and without (N=145) patient participation in six breast and gynecologic cancer centers. We performed t tests for within- and between-group comparisons and linear regression with "patients' perceived SDM experiences in MTC" as the dependent variable.

RESULTS

Patients' perceived SDM experiences increased at 4 weeks after MTC (p<0.001) with lower perceived SDM experiences for participating versus nonparticipating patients (p<0.001). Linear regression showed that the organizational variable "round table seating arrangement" was significantly associated with higher perceived SDM experiences compared with a theater or U-shape arrangement (beta=-0.38, p=0.043; beta=-0.69, p=0.010) directly after MTC.

CONCLUSION

Results provide first insights into patients' perceived SDM experiences in MTCs. SDM in MTCs is associated with organizational variables of MTCs. A round table seating arrangement in MTCs with patient participation seems important for patients' perceived SDM experiences. The relatively low perceived SDM experiences of participating patients directly after MTC indicates room for improvement, eg concerning patient-centered communication.
