Are testers also admitters? Comparing emergency physician resource utilization and admitting practices.

Area of Science:

• Emergency Medicine
• Health Services Research
• Physician Practice Patterns

Background:

• Physician practice patterns in emergency departments (EDs) exhibit significant variability.
• Understanding the drivers of this variability, such as resource utilization and admission decisions, is crucial for healthcare efficiency.

Purpose of the Study:

• To investigate the relationship between individual emergency physician resource utilization and patient admission rates.
• To quantify the association between the use of diagnostic and therapeutic resources and the likelihood of patient admission.

Main Methods:

• A retrospective observational study was conducted in two EDs.
• Observed-to-expected (O/E) ratios for resource utilization (IVs, labs, imaging) and admission rates were calculated for each physician.
• Correlations between resource utilization O/E ratios and admission rate O/E ratios were analyzed.

Main Results:

• Statistically significant positive correlations were found between physician resource utilization and admission rates.
• Physicians with higher resource utilization demonstrated higher admission rates, and vice versa.
• A clear trend indicated that increased use of ED resources was associated with increased patient admissions.

Conclusions:

• Emergency physician resource utilization and patient admission rates are positively correlated.
• Physicians utilizing more ED resources tend to admit a higher proportion of their patients.
• These findings contribute to the understanding of physician-specific variability in emergency care.
