Medium Range Theory of the Nursing Diagnosis Aspiration Risk in Critical Patients.
Nursing Theory; Respiratory Aspiration; Intensive Care Unit; Critical Care.
Midrange theory of nursing diagnoses in specific populations allows establishing causal relationships between its elements. Thus, this study aims to develop a mid-range theory of the nursing diagnosis of risk of aspiration in critically ill patients. This is a methodological study, based on the theoretical references of Roy and Lopes e Silva. It will be operationalized in 5 steps. The first step will consist of developing a scoping review on the subject and will follow the structure recommended by the international PRISMA guide. The research question was formulated according to the PCC mnemonic, in which the P (population) is- patients; C (concept) - Risk of aspiration; C (context) - Intensive Care Unit. It will use the descriptors Patients, Respiratory Aspiration and Intensive care unit/critical care. Studies published in the last 10 years that address the subject will be included. Duplicate studies and in the format of editorials, letters to the editor, opinion articles, reflection studies and books are excluded. The second step will consist of defining the main concepts of mid-range theory (essential attributes and clinical background) and their operational definitions. In the third step, a pictogram will be developed. In the fourth stage, the propositions of the theory will be built. In the fifth step, causal relationships and evidence for practice will be established. Data will be organized into tables and figures. Thus, it is expected, from the mid-range theory of the nursing diagnosis developed aspiration risk, to identify the causal relationships between the risk factors observed in patients hospitalized in the intensive care unit and how they influence this phenomenon and thus contribute to the advancement of nursing knowledge in this area.
