The present study aimed to clarify nursing knowledge required of newly graduated nurses in intensive care units (ICUs). Data were collected by interviewing 12 specialists comprising doctors, nurses practicing in ICUs, and teachers at nursing schools. The interview transcripts were analyzed by text mining.
The results showed that the most frequently cited word regarding nursing knowledge required in ICUs was "patient", followed by "respirator", "drug", "breath", "basis", "somatic normal", "circulation", "heart", "blood pressure", "electrocardiogram", "somatic aberration", "dissection physiology", and "post-operation". Furthermore, a strong association was identified between the words "patient", "respirator", and "circulation". Using principal component analysis and cluster analysis (K-Means), these data were classified into the following five categories: "Basic knowledge required to detect early signs of somatic disorders through monitoring"; " Basic knowledge required to objectively assess patients based on their recovery processes"; "Basic knowledge about the mechanism of disease"; "Basic knowledge required to predict secondary complications from current information"; and "Basic knowledge about postoperative nursing care".
These categories reflect specific nursing knowledge required to care for patients in ICUs, who often require mechanical ventilation.
