TIMI Risk Score predicts early readmission

To assess if the TIMI Risk Score could predict early readmission.

869 consecutive admissions to a Scottish district general hospital with suspected acute coronary syndrome.

A computerised clinical information system was interrogated to verify readmission. Area under the receiver operator characteristic curve and chi-square test for trend between TIMI Risk Score and readmission rate were calculated.

Median follow up was 73 days. There was a strong association between TIMI Risk Score and readmission rate (chi-square test for trend, p<0.001), with an area under the receiver operator characteristic curve of 0.60 (95% C.I. 0.55-0.65).

The TIMI Risk Score can predict readmission. This study reinforces its utility as a tool for identifying patients more likely to benefit from aggressive intervention.
