Operational Definition of the Concept of Success in Peripheral Intravenous Catheterization in Hospitalized Children.

The objective of this study was to operationally define the concept of success in peripheral intravenous catheterization in children considering the Walker and Avant model. This is a methodological study, carried out through the following steps: concept selection, the definition of the analysis objective, identification of possible uses of the concept, determination of critical or essential attributes, construction of a model and opposite case, and identification of antecedents and consequences. The study was carried out based on a search in international databases from January to March 2021. The sample consisted of 47 studies conducted in 17 countries between 2008 and 2021. Five attributes, 20 antecedents, 10 consequences, and an empirical reference of the studied concept were identified. Also, 2 cases, model and opposite, were elaborated, and an operational definition of the concept was developed. The Walker and Avant method enabled the operationalization of the concept of success of peripheral intravenous catheterization in children based on attributes, antecedents and consequents, and model and opposite cases.
