The San Francisco Syncope Rule vs physician judgment and decision making

Area of Science:

• Emergency Medicine
• Clinical Decision Making
• Cardiology

Background:

• Syncope is a common presentation in emergency departments, often leading to significant morbidity and healthcare costs.
• Accurate risk stratification is crucial for appropriate patient management and resource allocation.

Purpose of the Study:

• To compare the diagnostic accuracy of the San Francisco Syncope Rule (SFSR) against physician judgment and decision-making in predicting serious outcomes in syncope patients.
• To evaluate the potential of the SFSR to reduce hospital admissions for low-risk syncope patients.

Main Methods:

• A prospective cohort study involving 684 syncope visits.
• Physicians assessed patients and predicted the likelihood of serious outcomes.
• Patients were followed for 7 days to identify serious outcomes; receiver operating characteristic (ROC) curve analysis was used.

Main Results:

• The SFSR demonstrated a higher area under the ROC curve (0.92) compared to physician judgment (0.89) and physician decision-making (0.83).
• Physicians admitted 28% of low-risk patients, with a median stay of 1 day.
• The SFSR could potentially decrease admissions by 10% in low-risk patients while identifying all serious outcomes.

Conclusions:

• Physician judgment is effective but often leads to over-admission of low-risk syncope patients.
• The SFSR exhibits superior performance to current physician practices and can aid in optimizing syncope patient management.
• Implementing the SFSR may lead to more efficient healthcare resource utilization.
