Variation among cleft centres in the use of secondary surgery for children with cleft palate: a retrospective cohort study
Abstract
To test whether cleft centres vary in their use of secondary cleft palate surgery, also known as revision palate surgery, and if so to identify modifiable hospital- and surgeon-factors that are associated with use of secondary surgery. Retrospective cohort study. Forty-three paediatric hospitals across the United States. Children with cleft lip and palate who underwent primary cleft palate repair from 1999 to 2013. Time from primary cleft palate repair to secondary palate surgery. We identified 4,939 children who underwent primary cleft palate repair. At ten years after primary palate repair, 44% of children had undergone secondary palate surgery. Significant variation existed among hospitals (p<0.001); the proportion of children undergoing secondary surgery by 10 years ranged from 9% to 77% across hospitals. After adjusting for patient demographics, primary palate repair before nine months of age was associated with an increased hazard of secondary palate surgery (initial hazard ratio 6.74, 95% CI 5.30-8.73). Postoperative antibiotics, surgeon procedure volume, and hospital procedure volume were not associated with time to secondary surgery (p>0.05). Of the outcome variation attributable to hospitals and surgeons, between-hosp...Continue Reading
