One-year follow-up of patients undergoing elective cardiac surgery assessed with the Comprehensive Assessment of Frailty test and its simplified form

Assessment of perioperative risk of elderly patients in cardiac surgery is demanding. Most of the commonly used cardiac surgery risk scores over-or underestimate individual risk. Therefore, we recently developed a 'frailty score', the comprehensive assessment of frailty (CAF) score that showed a good prediction of 30-day mortality. The aim of the study was to evaluate the ability of the new score predicting one-year outcome. CAF was preoperatively applied to 400 patients ≥ 74 years that were admitted to cardiac surgery between September 2008 and January 2010. For 213 of these patients one-year follow-up was assessed by telephone interview until April 2010. One hundred and ten male and 103 female patients were included. Twenty-five percent underwent isolated coronary revascularization, 35% isolated valve procedures and 26% underwent combined procedures. One-year mortality was 12.2%. Patients who died within one year had a median frailty score of 16 [5;33] compared to 11 [3;33] to the one-year survivors (P=0.001). A new, easily applicable score ('Frailty predicts death One yeaR after Elective Cardiac Surgery Test') was built out of the basic score and showed a promising ability to predict one-year mortality. CAF is a new additional tool to assess prognosis of elderly patients before cardiac surgical interventions. The 'CAF' score facilitates prediction of mid-term outcome of high-risk elderly patients.
