Understanding Patient Perspectives Toward Shared Decision Making in Patients with Pulmonary Hypertension.

Clinical guidelines for pulmonary hypertension (PH) recommend shared decision making (SDM) and individualized treatment. However, patient perspectives on PH treatment goals, preference toward a decision-making style of treatment, and adoption of SDM remain unclear. This cross-sectional questionnaire-based study assessed the patients' preferred and actual participation role in treatment decision-making, rated on 5 scales (ranging from passive [patients leave all decisions to physicians] to active [patients make the decision after physicians show patients several options]) and evaluated the concordance between preferred and actual participation roles. The important factors underlying patients' perspectives in treatment decision-making (i.e., prognosis; symptom, financial, family, and social burdens; patient values; and physician recommendation) were evaluated. Univariate logistic regression analysis was performed to determine the patients with a positive preference toward "physician recommendation" in treatment decision-making. Among 130 patients with PH (median age: 58 years, mean pulmonary arterial pressure: 23 mmHg, 27.7% male), 59.2% preferred that "physicians make the decision regarding treatment after showing patients therapeutic options (i.e., intermediate between passive and active roles)." The patient-preferred and actual participation roles in decision-making had moderate agreement (Cohen's kappa=0.46). The most important factor in treatment decisions was "symptom burden reduction" (93.8%). While 85.0% of patients chose "physician recommendation" as an important factor, 49.6% chose "alignment with my values." The determinants of patients who chose "physician recommendation" were less severe hemodynamics and better functional capacity. In conclusion, PH patients preferred that the "physicians make the decision after showing patients therapeutic options" and prioritized physician recommendation over their values.
