Suboptimal Diagnostic Decisions In Hospitalized Patients with Fever: A Prospective Record Review with Physician
Background:
The medical diagnostic process is vulnerable to suboptimal decision-making (that is, decisions with any deviation from an optimal diagnostic process) due to its complex nature. It is unknown how these suboptimal diagnostic decisions and other measures of diagnostic safety (diagnostic error, diagnostic discrepancy) relate to each other.
Methods:
The authors prospectively included a convenience sample of 53 hospitalized patients with fever between February and May 2023. After discharge, independent internal medicine physicians reviewed their medical records to identify suboptimal diagnostic decisions and diagnostic errors. When such suboptimal decisions were observed, involved physicians were interviewed about the thought processes behind these decisions. Established tools and taxonomies were used to identify and categorize suboptimal diagnostic decisions, diagnostic errors, and diagnostic discrepancies.
Results:
The authors initially identified a total of 110 suboptimal diagnostic decisions in 38 of 53 cases (71.7%). After the physician interviews, 29 cases with suboptimal decisions remained (54.7%), with a total of 72 suboptimal diagnostic decisions across those cases (median of 2 suboptimal decisions per case; interquartile range 1-4). Cases with a higher number of suboptimal diagnostic decisions had significantly higher rates of diagnostic error and diagnostic discrepancy. No significant association between diagnostic error and diagnostic discrepancy were found. Almost all suboptimal decisions were human, and most took place during assessment of the patient and diagnostic testing.
Conclusion:
Cases with more suboptimal diagnostic decisions were associated with higher rates of diagnostic error and diagnostic discrepancy, but the level of overlap between the three was relatively low, suggesting that these reflect different concepts of diagnostic safety and should be treated as such. Future research should incorporate physician interviews to enrich understanding and account for contextual factors.
Insights
Suboptimal diagnostic decisions in hospitalized patients correlate with increased diagnostic error and discrepancy. However, these measures of diagnostic safety appear distinct and require separate consideration in future research.
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.
