The relationship between task complexity and decision-making consistency

Area of Science:

• Nursing
• Decision Science

Background:

• Clinical decision-making is complex.
• Assessing decision consistency is crucial for patient safety.

Purpose of the Study:

• To investigate the relationship between task complexity and decision-making consistency in nurses.
• To evaluate nurses' clinical decisions against a normative decision model.

Main Methods:

• A stratified random sample of 101 medical-surgical nurses participated.
• The Decision Analytic Questionnaire (DAQ) was used to assess decision-making.
• Probit analysis was employed to model decision-maker profiles.

Main Results:

• Nurses' decisions aligned with the normative model.
• Agreement decreased as task complexity increased (p < .005).
• Decision consistency was task-specific and required more predictors with increased complexity.

Conclusions:

• Task complexity significantly impacts nurses' decision-making consistency.
• The normative decision model provides a benchmark for evaluating clinical judgment.
• Further research is needed to identify predictors of consistency in complex tasks.
