Herd Behavior in Medicine: Examples From COVID-19.

Area of Science:

• Medical practice and public health
• Behavioral science in healthcare
• Pandemic response strategies

Background:

• Herd behavior, defined as group conduct without individual thought, was observed in healthcare settings.
• Wilfred Trotter first coined the term in 1914, highlighting its long-standing presence.
• The coronavirus disease 2019 (COVID-19) pandemic provided recent examples of this phenomenon.

Discussion:

• The editorial examines herd behavior's impact on the healthcare industry, using COVID-19 interventions as case studies.
• Initial pandemic interventions, including personal protective equipment (PPE), fever clinics, and telemedicine, were sometimes adopted without thorough evaluation.
• Some interventions proved ineffective or only beneficial for specific patient groups, necessitating critical assessment.

Key Insights:

• Herd behavior can lead to the widespread adoption of unproven or suboptimal medical interventions.
• The rapid, uncritical implementation of non-medical interventions like PPE and telemedicine during COVID-19 illustrates this effect.
• A critical need exists for rigorous evaluation of medical evidence, especially during public health crises.

Outlook:

• Certain beneficial interventions adopted during the pandemic, such as telemedicine, are likely to persist.
• The editorial advocates for a shift towards evidence-based decision-making to mitigate the risks of herd behavior in future pandemics.
• Strengthening critical appraisal skills within the medical community is essential for navigating complex health challenges.
