Objective: Concerns of increased time consumption and of the impact on clinical decisions may restrain doctors from shared decision making (SDM). This paper evaluates consultation length and decisions made when using an in-consult patient decision aid (PtDA).Methods: This prospective cohort study compared an unexposed cohort with a cohort exposed to SDM and a PtDA in two preference-sensitive decision situations: invasive lung cancer diagnostics and adjuvant treatment for early breast cancer. Outcome measures were consultation length and decisions made.Results: The study included 261 consultations, 115 were in the SDM-exposed cohort. Consultations were inconsiderably longer in the SDM cohort; 2 min, 11 s (p = 0.2217) for lung cancer diagnostics and 3 min, 57 s (p = 0.1128) for adjuvant breast cancer treatment. In lung cancer diagnostics, consultation length became more uniform and decisions tended to become conservative after introduction of SDM. For adjuvant breast cancer, slightly more patients in the SDM cohort chose to decline treatment.Conclusion: Shared decision making did not take significantly longer time and led to slightly more conservative decisions.Practice Implications: SDM may be implemented without considerable impact on consultation length. The impact on clinical decisions depends mainly on the clinical situation. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to describe the impact on patient-reported outcomes of introducing Shared Decision Making (SDM) and a Patient Decision Aid (PtDA) in the initial process of lung cancer diagnostics.Methods: We conducted a prospective cohort study, where a control cohort was consulted according to usual clinical practice. After introducing SDM through a PtDA and training of the staff, the SDM cohort was enrolled in the study. All patients completed four questionnaires: the Decisional Conflict Scale (DCS) before and after the consultation, the CollaboRATE scale after the consultation, and the Decision Regret Scale (DRS).Results: Patients exposed to SDM and a PtDA had significantly improved DCS scores after the consultation compared to the control group (a difference of 10.26, p = 0.0128) and significantly lower DRS scores (a difference of 8.98, p = 0.0197). Of the 82 control patients and 52 SDM patients 29% and 54%, respectively, gave the maximum score on the CollaboRATE scale (Pearson's chi2 8.0946, p = 0.004).Conclusion: The use of SDM and a PtDA had significant positive impact on patient-reported outcomes.Practice Implications: Our results may encourage the increased uptake of SDM in the initial process of lung cancer diagnostics.
