Clinical decision aids for chest pain in the emergency department: identifying low-risk patients

Area of Science:

• Emergency Medicine
• Cardiology
• Clinical Decision Support

Background:

• Chest pain is a common emergency department complaint, with acute coronary syndrome (ACS) posing significant morbidity and mortality risks.
• Atypical ACS presentations and extensive workups contribute to diagnostic challenges and healthcare costs.
• Effective risk stratification is essential for timely diagnosis and appropriate patient management.

Purpose of the Study:

• To review and compare various chest pain decision aids for risk-stratifying patients in the emergency department.
• To evaluate the performance of different decision aids in identifying acute coronary syndrome (ACS) and low-risk patients.
• To guide healthcare providers in selecting the most suitable decision aid for their clinical practice.

Main Methods:

• Review of established and contemporary chest pain decision aids, including TIMI, GRACE, ASPECT, ADAPT, NACPR, and HEART scores.
• Analysis of the development and validation of these tools in both diagnosed and undifferentiated chest pain populations.
• Comparative assessment of the merits and limitations of each decision aid.

Main Results:

• Early prognostic aids like TIMI and GRACE scores were adapted for undifferentiated chest pain.
• Newer tools such as ASPECT, ADAPT, NACPR, and HEART scores show improved performance in undifferentiated chest pain.
• Each decision aid offers distinct advantages and disadvantages for clinical application.

Conclusions:

• Selecting the appropriate chest pain decision aid is critical for optimizing ACS diagnosis and patient care in the emergency department.
• Decision aids that accurately identify ACS and effectively stratify low-risk patients can streamline workups and reduce unnecessary testing.
• Understanding the relative merits and limitations of various tools empowers providers to tailor diagnostic strategies to their specific clinical setting.
