ABSTRACT

BACKGROUND: Assessing patient fitness prior to high-risk operations is becoming increasingly vital in cardiothoracic surgery. Physical activity (PA) and frailty measures are powerful perioperative tools, albeit underused in clinical practice. This study aimed to assess the influence of patient frailty on PA postsurgery and other short-term outcomes. METHODS: Eighty patients undergoing a variety of cardiac surgical procedures (coronary revascularisation, valve repair/replacement, or combination) were recruited to participate. The Reported Edmonton Frailty Scale was used to measure preoperative frailty. As objective measures of PA, participants wore a wrist accelerometer device for 14 days prior to their operation and early in the postoperative period for 30 days. RESULTS: A global reduction in PA was observed in the early postoperative period. Frailty was a significant predictor of reduced light (coefficient -2.23, 95% CI -4.21 to -0.25, P = .028) and moderate activity (coefficient -1.85, 95% CI -2.99 to -0.70, P = .002) postoperatively. Neither frailty nor preoperative PA were predictors of postoperative composite complications. Both frailty (coefficient 0.134, 95% CI 0.106-0.162, P < .001) and PA scores (P < .05) were strong predictors of length of hospital stay (coefficient 1.76, 95% CI 0.003-3.524, P = .05). Furthermore, patients who stayed in hospital longer were more likely to suffer early postoperative complications (stroke, renal failure, reoperation, pacemaker) if they were frail (P < .0001) compared to non-frail patients (P = .607). CONCLUSIONS: This study highlights the predictive ability of objective frailty scoring and PA measurement for outcomes after cardiac surgery. This has important implications for surgical risk stratification and personalized postoperative planning.
