TIMI Risk Score predicts early readmission

Aim To assess if the TIMI Risk Score could predict early readmission. Participants 869 consecutive admissions to a Scottish district general hospital with suspected acute coronary syndrome. Methods 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. Results 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). Conclusion 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.
