Evaluation of a multilevel implementation program for timeout and shared decision making in breast cancer care: a mixed methods study among 11 hospital teams.

Objective: Evaluation of a multilevel implementation program on shared decision making (SDM) for breast cancer clinicians.

Methods: The program was based on the 'Measurement Instrument for Determinants of Innovations-model' (MIDI). Key factors for effective implementation were included. Eleven breast cancer teams selected from two geographical areas participated; first six surgery teams and second five systemic therapy teams. A mixed method evaluation was carried out at the end of each period: Descriptive statistics were used for surveys and thematic content analysis for semi-structured interviews.

Results: Twenty-eight clinicians returned the questionnaire (42%). Clinicians (96%) endorse that SDM is relevant to breast cancer care. The program supported adoption of SDM in their practice. Limited financial means, time constraints and concurrent activities were frequently reported barriers. Interviews (n = 21) showed that using a 4-step SDM model - when reinforced by practical examples, handy cards, feedback and training - helped to internalize SDM theory. Clinicians experienced positive results for their patients and themselves. Task re-assignment and flexible outpatient planning reinforce sustainable change. Patient involvement was valued.

Conclusion: Our program supported breast cancer clinicians to adopt SDM.

Practice Implications: To implement SDM, multilevel approaches are needed that reinforce intrinsic motivation by demonstrating benefits for patients and clinicians.
