Abstract
BACKGROUND: Respiratory complications are the leading cause of morbidity in patients undergoing tracheobronchoplasty, yet risk stratification systems on this population are insufficient. We investigated the association between frailty and risk of major respiratory complications after tracheobronchoplasty. METHODS: A retrospective review was made of 161 consecutive tracheobronchoplasties (October 2002 to September 2016). A frailty index was developed by the deficit-accumulation approach comprising 26 multidomain preoperative variables. The main outcome was a composite endpoint of major respiratory complications within 30 days of surgery. Odds ratio (OR) and 95% confidence interval (CI) were estimated using logistic regression. RESULTS: The cohort consisted of 103 women (64%), median age of 58 years (interquartile range, 51 to 66) and median FI of 0.25 (interquartile range, 0.1 to 0.3). Forty-eight patients (30%) had respiratory complications, the most common being respiratory failure (n = 27, 16.8%) and pneumonia (n = 25, 15.5%). Severe frailty (frailty index ≥0.33) was strongly associated with major respiratory complications (73.8% versus 2.5%; OR 58.8, 95% CI: 9.6 to 358.3). The association with severe frailty appeared stronger for respiratory failure (47.6% versus 2.5%; OR 30, 95% CI: 4.7 to 189.9) than for pneumonia (40.5% versus 0%; OR 35.2. 95% CI: 2.0 to 599.8). Further adjustment for intraoperative crystalloid volume or forced expiratory volume in 1 second moderately attenuated the association between frailty with major respiratory complications (OR 17.4. 95% CI: 2.0 to 150.8), respiratory failure (OR 13.1, 95% CI: 1.7 to 95.8), and pneumonia (OR 20.1, 95% CI: 1.1 to 341.8). CONCLUSIONS: Frailty, as indicated by frailty index, was associated with major respiratory complications, particularly respiratory failure after tracheobronchoplasty. Preoperative identification of frailty may help guide decision making for patients considering this effective, although arduous procedure.
