Suboptimal Diagnostic Decisions In Hospitalized Patients with Fever: A Prospective Record Review with Physician...

Area of Science:

• Medical diagnostics
• Patient safety
• Clinical decision-making

Background:

• The complexity of medical diagnosis can lead to suboptimal decision-making.
• The relationship between suboptimal diagnostic decisions, diagnostic error, and diagnostic discrepancy is not well understood.

Purpose of the Study:

• To investigate the relationship between suboptimal diagnostic decisions and other measures of diagnostic safety, including diagnostic error and diagnostic discrepancy.
• To explore the overlap and distinctions between these concepts in hospitalized patients.

Main Methods:

• Prospective study of 53 hospitalized patients with fever.
• Independent physician review of medical records to identify suboptimal decisions and errors.
• Physician interviews to understand decision-making processes.
• Utilized established tools for categorization of diagnostic safety measures.

Main Results:

• 71.7% of cases initially showed suboptimal diagnostic decisions, reduced to 54.7% after interviews.
• A higher number of suboptimal decisions correlated with increased diagnostic error and discrepancy.
• No significant association was found between diagnostic error and diagnostic discrepancy.
• Most suboptimal decisions were human-related, occurring during patient assessment and testing.

Conclusions:

• Suboptimal diagnostic decisions are linked to higher rates of diagnostic error and discrepancy.
• These diagnostic safety measures represent distinct concepts with limited overlap.
• Future research should integrate physician interviews to capture contextual factors influencing diagnostic safety.
