ABSTRACT
Objective
to construct a middle range theory for developing the excessive fluid volume risk diagnostic proposition in patients undergoing hemodialysis.
Method
this is a methodological study, developed for the theoretical-causal validity of a nursing diagnosis. The study was carried out in four stages: study selection, identification of the main concepts of the theory, pictogram construction and proposition elaboration. These steps were operationalized through an integrative literature review, with a sample of 82 articles selected from the Web of Science, PubMed, CINAHL, Scopus and Science Direct databases.
Results
the data extracted from the sample articles enabled identifying five essential terms to define excessive fluid volume risk. Furthermore, 31 etiological factors of excessive fluid volume risk were identified, in addition to a pictogram and 12 propositions.
Conclusion and implications for practice
the construction of a middle-range theory focused on excessive fluid volume risk in patients undergoing hemodialysis refines terminology and expands the understanding of nursing phenomena. Thus, the data from this research will provide clear and robust knowledge for the conduct of nurses’ actions in clinical practice.
