PURPOSE.
To determine the extent possible of developing an unequivocal formulation of a conceptual, structural, and contextual definition of “patient outcomes,” and the possibility of coming to an agreement on the criteria for classification of patient outcomes.
METHODS.
An international Delphi survey of 33 experts.
FINDINGS.
A conceptual, structural, and contextual definition of patient outcomes and priorities for the characteristics of patient outcome classification.
CONCLUSIONS.
The authors recommend the unequivocalness of nursing terminology, not only for reasons of effectiveness and efficiency, but also to clarify the nursing vocabulary for epistemological reasons.
