Decision analysis as a tool to support an analytical pattern-of-reasoning.

Abstract

Decision analysis is offered as a tool to aid nurses' decision-making in complex and troublesome situations where there are mutually exclusive actions and time is available for deliberation. Decision analysis can be formal or informal. Formal decision analysis provides a structure for representing the decision situation and a mathematical procedure for prescribing the alternative action that is most consistent with what is known and what one values. Informal decision analysis uses the concepts and sometimes the structure of decision analysis, but usually does not include the mathematical calculations. In the present paper, the authors illustrate how formal and informal decision analysis might be used by nurses to: (i) enhance their own decision-making; (ii) assist patients or family caregivers with decision-making and; (iii) promote informed health care policy development. Finally, the advantages and limitations of decision analysis are discussed.
