On a daily basis, clinicians make decisions regarding therapies to result
in the best outcome for their patients. These decisions should be based on the
evidence in the literature, indicating a therapy will cause the best outcome.
To facilitate this, many professional societies and scientific journals have
published technical and scientific reviews, as well as evidence-based
standards of care focused on many issues of nutrition support practice. This
paper provides an overview of how these reviews and standards of care are
derived to promote both the understanding of what they can and cannot do to
enhance clinical practice.
