Figure 7. Three types of evaluations assessing the results of implementing PSPs Assessing the Evidence for Context-Sensitive Effectiveness and Safety 1. Effectiveness QuestionsIs the study PSP more effective than usual care?Is the study PSP more effective in reducing patient harm than an alternate approach?2. Implementation Experience QuestionsWhat changes occur in the clinical or economic performance of the study organization/organizational unit during/after implementation of the study PSP?What changes occur in staff/clinician culture/attitudes during/after implementation?3.
