Prospective and Explicit Clinical Validation of the Ottawa Heart Failure Risk Scale, With and Without Use of Quantitative NT‐proBNP
Why the study?
Does the Ottawa Heart Failure Risk Scale (OHFRS) improve sensitivity for predicting serious adverse events in acute heart failure patients in the emergency department compared to actual practice?
Population
1,100 patients with acute heart failure evaluated in the emergency department, mean age 77.7 years.
Comparison
Ottawa Heart Failure Risk Scale score > 1 as an… vs Actual clinical practice
Design
Cohort
Follow-up
30 days

Implication
OHFRS may aid ED disposition for acute HF with high sensitivity; leaves open impact on admissions and need for implementation trials.
Structured PICO

P
Population
1,100 patients with acute heart failure evaluated in the emergency department, mean age 77.7 years.
I
Intervention
Ottawa Heart Failure Risk Scale (OHFRS) score > 1 as an admission threshold, with and without quantitative NT-proBNP
C
Comparator
Actual clinical practice
O
Outcome
Serious adverse event (SAE) defined as death within 30 days, admission to monitored unit, intubation, noninvasive ventilation, myocardial infarction, or relapse resulting in hospital admission within 14 dayscomposite
The Ottawa Heart Failure Risk Scale is highly sensitive for predicting serious adverse events in ED patients with acute heart failure, especially when combined with NT-proBNP, though it may increase admission rates.
