Systematic biases in group decision-making: implications for patient safety

Area of Science:

• Healthcare Management
• Organizational Psychology
• Decision Science

Background:

• Modern healthcare relies heavily on group decision-making.
• Imperfect group decisions can lead to clinical and organizational errors, harming patients.
• Historical health scandals underscore the risks associated with group decision-making failures.

Purpose of the Study:

• To explore how systematic biases in group decision-making can threaten patient safety in healthcare.
• To identify specific biases: groupthink, social loafing, group polarization, and escalation of commitment.
• To propose organizational strategies to mitigate these adverse effects.

Main Methods:

• Drawing on theories from organization studies and decision science.
• Analyzing four systematic group biases: groupthink, social loafing, group polarization, and escalation of commitment.
• Describing antecedents, impact on patient safety, and remedial strategies for each bias.

Main Results:

• Groupthink, social loafing, group polarization, and escalation of commitment can impair group decisions regarding patient safety.
• Each bias has identifiable antecedents and can lead to adverse patient outcomes.
• Potential organizational strategies exist to reduce the impact of these biases.

Conclusions:

• Systematic biases in group decision-making pose a significant threat to patient safety in healthcare.
• Addressing these biases requires understanding their origins and implementing targeted organizational interventions.
• Further research is needed in this neglected area of patient safety.
