Data Collection
The data of the original cohort were collected from an instrument based on the defining characteristics of IBP, IAC, and IGE, as described in NANDA International terminology (NANDA-I) (Herdman & Kamitsuru, 2014) and in the relevant literature on pulmonary evaluation (Jarvis, 2011, Potter and Perry, 2012). Operational definitions were created for each defining characteristic studied, and the data were collected by members of a research group on nursing diagnoses who had previously completed to an eight-hour training for review and standardization of the diagnostic procedures used in respiratory evaluation.
