Identifying high-quality bariatric surgery centers: hospital volume or risk-adjusted outcomes?
Risk-adjusted morbidity is much better than hospital volume at predicting future performance with bariatric surgery. Rather than focusing on volume, accreditation and centers of excellence programs should focus more on directly measuring outcomes.
Experimental evidence to evaluate the benefits and risks in preterm infants of early discharge from hospital with home gavage feeding compared with later discharge upon attainment of full sucking feeds is limited to the results of one small quasi-randomised controlled trial. High quality trials with concealed allocation, complete follow-up of all randomised infants and adequate sample size are needed before practice recommendations can be made.
