Evidence of content validity of the "Blood Transfusion Reaction" (code 0700) nursing outcome from the nursing outcomes classification.

Abstract

Objective: The objective of study was to present evidence of the content validity of conceptual and operational definitions of the "Blood Transfusion Reaction (code 0700)" nursing outcome from the Nursing Outcomes Classification (NOC).

Method: A methodological study was implemented in four phases. The first phase consisted of a narrative literature review in which the main indicators related to blood transfusion were identified: 25 new indicators that were not present in NOC, in addition to 14 existing indicators, for a total of 39 to be studied. In the second phase, conceptual and operational definitions, and magnitude of NOC indicators were developed. The third phase consisted of analysis of evidence of content validity of conceptual and operational definitions of indicators, through assessment by experts. In the fourth phase, a pilot test was applied to 40 electronic medical records of patients who received blood components and presented with a transfusion reaction.

Results: A total of 27 articles were analyzed and served as support to develop conceptual and operational definitions, and magnitude of indicators, considered for the outcome under study. It was assessed by a group of 10 experts, requiring three rounds to reach the established critical content validity ratio in which four of these indicators were excluded, leaving 35 indicators in the final version. A pilot test on 40 records revealed the presence of 13 indicators, of which six were present in the classification.

Conclusion: The conceptual and operational definitions and magnitude developed for the "Blood Transfusion Reaction (code 0700)" nursing outcome demonstrated adequate evidence of content validity in the 21 indicators found in the literature, along with 14 indicators already present in NOC, and 13 of these indicators were present in patients receiving blood components who presented a transfusion reaction.

Implications for practice: Nurses can use this nursing outcome as a clinical assessment tool for monitoring blood transfusion recipients' clinical signs.
