Description: The purpose of this investigation was to generate a substantive theory of clinical reasoning among nurses who care for confused older patients in the hospital. Analysis was undertaken to discover factors which lead to the failure to detect and manage acute confusional states in this patient population. A Grounded Dimensional Analysis approach to inquiry and analysis was employed.

A purposive sample of 20 registered nurses with at least two years of acute care experience was interviewed. Interviews were semi-structured according to a theoretical sampling technique and were tape-recorded. Data were transcribed and then analyzed according to the techniques of dimensional analysis in which conceptualization emerges from the data to specify and define the context and consequences of phenomena.

Results of the analysis revealed that nurses who work with the elderly in acute care settings have different philosophical orientations towards basic health in aging. These orientations serve as perspectives which influence their thinking and action. Perspectives condition the ways in which older people are judged and are ultimately dealt with in the clinical arena by nurses.

Three philosophical orientations were identified. They were referred to as: (1) Decline Perspective, (2) Vulnerable Perspective, and (3) Healthful Perspective. According to these perspectives, nursing views about aged health vary along a continuum ranging from a notion of aging health as decremental to aging health as intact. Corresponding patterns of clinical reasoning were reflective of these contrasting notions.

The three patterns of clinical nursing reasoning differed relative to the nature of observations made, the meaning attached to these observations, and to the nursing actions taken. Findings from this study suggest that nurses who use the Decline Perspective when making clinical judgments are least likely to identify acute confusional states in older patients. Those nurses who reason from the Healthful Perspective are most apt to differentiate between acute and chronic confusions. Lastly, the outcome of decisions made by nurses who use the Vulnerable Perspective are difficult to predict because of the ambiguity which pervades all aspects of their clinical reasoning.

Since the three reasoning patterns identified are more particular than the general model of clinical judgment traditionally described, the results from this dissertation study provide a more complete understanding of the processes and nuances involved in nursing decision-making related to a specific clinical situation. Predictions about the quality of nursing care provided to older confused patients can be made based upon these findings.
