Why the study?

Does routine pulse checking improve the detection of atrial fibrillation in patients with non-cardioembolic stroke during rehabilitation?

Key Points

Evaluate potential explanations for why routine pulse checking during stroke rehabilitation failed to detect atrial fibrillation in the ESCORT study despite patients possessing elevated arrhythmia risk.
Analyzed findings from the ESCORT study involving 158 inpatients undergoing rehabilitation for non-cardioembolic stroke over a median observation period of 179 days.
Reviewed screening protocols where therapists checked pulse for 15 seconds before, during, and after rehabilitation, triggering electrocardiogram confirmation if irregular pulse or tachycardia was noted.
Compared patient demographics and estimated incident atrial fibrillation risks against general population screening data and the Suita study risk score.
Zero cases of tachycardia or atrial fibrillation were detected among the 158 patients during rehabilitation, even among the four patients who experienced recurrent stroke events.
The projected development of atrial fibrillation over a 6-month period was estimated at 0.125% based on population incidence (2.5/1,000 person-years), rendering zero detections unsurprising in 158 patients monitored for a median of 179 days.
Patients had a median age of 77 years (interquartile range, 71-84) and Suita risk scores between 9 and 20 points, corresponding to an estimated 10-year incident atrial fibrillation risk between 7% and 27%.

Structured PICO

Does routine pulse checking improve the detection of atrial fibrillation in patients with non-cardioembolic stroke during rehabilitation?

P

Population

158 older adults (median age 77) with non-cardioembolic stroke undergoing in-patient rehabilitation, followed for a median of 179 days.

E

Exposure

Pulse checking before, during, and after rehabilitation, followed by an ECG if an irregular pulse or tachycardia was detected.

O

Outcome

Detection of new-onset atrial fibrillation.

Limitations

Small sample size
Short observation period (median 179 days)
Checking pulse for only 15 seconds may underestimate paroxysmal atrial fibrillation
Unknown rate of embolic stroke of undetermined source (ESUS)
small sample size
short observation period
simple pulse checking method
unknown ESUS rate

Implication

Despite the negative findings of the ESCORT study, routine pulse checking during rehabilitation remains a recommended, low-cost strategy for detecting incident atrial fibrillation in patients with non-cardioembolic stroke.
