Description: Statement of the problem. The purpose of this qualitative study was to describe how expert, pediatric, critical care nurses make decisions during critical incidents in a pediatric intensive care unit. The research questions were: (1) What are the diagnostic reasoning behaviors of the expert nurse in a pediatric intensive care setting? (2) What cognitive processes do expert, pediatric critical care nurses use to generate effective diagnoses? (3) Do expert, pediatric critical care nurses use similar reasoning behaviors that have been described in other settings? (4) Do expert pediatric critical care nurses' reasoning behaviors fit the skill acquisition model proposed by Elstein et al. (1978)? (5) Do expert, pediatric critical care nurses' reasoning behaviors fit the skill acquisition model proposed by Dreyfus (1986)? (6) Can the diagnostic reasoning behaviors of expert, pediatric critical care nurses be described using both the Elstein and the Dreyfus model? (7) To what extent do variables such as length of time caring for the patient influence diagnostic reasoning strategies of expert, pediatric critical care nurses?.

Procedure and methods. The researcher observed four expert, pediatric, critical-care nurse subjects during critical incidents in the intensive care unit. Detailed notes of the subjects' actions, verbalizations, and patient monitor readings were taken. Following each shift, the subject was interviewed regarding decision making during the shift. The interviews were tape recorded, transcribed to text, and the content categorized. The data generated 8 major categories and 23 subcategories. Frequency counts and percentages of the major categories and subcategories were calculated for each subject and the total group.

Results. The 4 major categories with the highest percentage of themes coded for the subjects were: deciding and understanding the patient problem (22%), gathering information about the patient (18%), interacting with the staff (18%), and deciding what to do (15%). The five subcategories with the highest percentage of themes were: gathering cues about the patient (13%), activating hypotheses about the patient (12%), similarity recognition (11%), doctor-nurse interaction (9%), and sense of salience (9%).

Conclusions. The conclusion is that expert, pediatric, critical nurses use aspects of both the analytical Elstein model of diagnostic reasoning and the Dreyfus model of skill acquisition in their decision making. The study's results support the need for a new decision making model in nursing. An additional finding was that doctor-nurse interaction is an important variable affecting nurses' decision making.
