Insights
The European Society of Cardiology (ESC) 0-hour/1-hour (0/1-h) algorithm for chest pain triage is effective and reduces healthcare costs. This guideline improves risk stratification and economic efficiency in managing patients with chest pain.
Area of Science:
- Cardiology
- Health Economics
Background:
- The European Society of Cardiology (ESC) recommends a 0-hour/1-hour (0/1-h) rule-out and rule-in algorithm using high-sensitivity cardiac troponin assays for chest pain patient triage.
- Implementing this guideline has potential economic implications for healthcare systems.
Purpose of the Study:
- To investigate the economic impact and cost-effectiveness of the ESC 0/1-h algorithm in Japan.
- To evaluate the algorithm's efficiency in risk stratification and cost reduction for chest pain presentations.
Main Methods:
- A post hoc cost-effectiveness analysis (DROP-ACS study) using deidentified electronic medical records from two Japanese diagnostic centers.
- Comparison of patient care using the 0/1-h algorithm (Hospital A) versus point-of-care testing (Hospital B).
- Clinical outcome assessed: all-cause mortality or myocardial infarction within 30 days.
Main Results:
- Hospital A (0/1-h algorithm) demonstrated high sensitivity (100%) and specificity (95.0%) for the clinical outcome.
- Hospital B (point-of-care testing) showed lower sensitivity (92.9%) and specificity (89.8%).
- Implementing the 0/1-h algorithm in Hospital B could decrease urgent coronary angiograms by 50% and reduce medical costs by approximately JPY 4 million.
Conclusions:
- The ESC 0/1-h algorithm is an efficient strategy for risk stratification in patients with chest pain.
- Adoption of the 0/1-h algorithm can lead to significant reductions in medical costs.
Background:
This study investigated the economic impact of the European Society of Cardiology (ESC) clinical practice guideline recommendation of using the 0-h/1-h rule-out and rule-in algorithm with high-sensitivity cardiac troponin assays (0/1-h algorithm) to triage patients presenting with chest pain.
Methods And Results:
This post hoc cost-effectiveness evaluation (DROP-ACS; UMIN000030668) used deidentified electronic medical records from health insurance claims from 2 diagnostic centers in Japan. A cost-effectiveness analysis was conducted with 472 patients with care provided following the 0/1-h algorithm (Hospital A) and 427 patients following point-of-care testing (Hospital B). The clinical outcome of interest was all-cause mortality or subsequent myocardial infarction within 30 days of the index presentation. The sensitivity and specificity for the clinical outcome were 100% (95% confidence interval [CI] 91.1-100%) and 95.0% (95% CI 94.3-95.0%), respectively, in Hospital A and 92.9% (95% CI 69.6-98.7%) and 89.8% (95% CI 89.0-90.0%), respectively, in Hospital B. If the diagnostic accuracy of the 0/1-h algorithm was implemented in Hospital B, it is expected that the number of urgent (<24-h) coronary angiograms would decrease by 50%. Incorporating this assumption, implementing the 0/1-h algorithm could potentially reduce medical costs by JPY4,033,874 (95% CI JPY3,440,346-4,627,402) in Hospital B (JPY9,447 per patient; 95% CI JPY 8,057-10,837 per patient).
Conclusions:
The ESC 0/1-h algorithm was efficient for risk stratification and for reducing medical costs.
