Randomized Controlled Trial
Decision aid influences on factors associated with patient empowerment prior to cancer treatment decision making.
Despite progress, models that incorporate antecedent and mediating factors associated with shared decision making (SDM)-related outcomes remain limited. An experimental study tests patient decision aid (DA) effects on a network of antecedents and mediators associated with patient empowerment prior to a medical decision-making consultation regarding cancer treatment. ⋯ Evidence from this research indicates that experiencing a DA prior to treatment decision making affects patient empowerment through a network that includes desire for information, life satisfaction, and multiple mediators. The studies also demonstrate the role that theory-based, multigroup structural equation modeling (SEM) can play in increasing understanding of DA effects. Such understanding is critical to improving SDM between patients and their physicians.

Linking patient-reported back pain outcomes with health utility measures is valuable for informing economic evaluations. ⋯ An empirical algorithm predicting EQ-5D weights from RMDQ scores provides a currently unavailable link for conducting economic evaluations in low back pain studies.
