The fifth step of the process, outcome evaluation, attempts to interpret the results and evaluate the outcomes of the applied evidence (intervention). Outcome measures may be psychosocial (quality of life, improved patient perception of care, reduction in depressive and anxiety symptoms), physiologic (improved health, reduced complications), or functional improvement. Evaluation of the process and the results may occur through peer assessment, audit, or even self reflection. Depending on the type of outcomes achieved, it may be possible to compare the outcomes of a study with similar outcomes on a local, regional, national, or international level.
