Abstract Objective To evaluate the quality of neonatal inherited metabolic diseases screening in Chaoyang District, Beijing Municipality from 2012 to 2021, so as to provide insights into improvements in the screening quality and efficiency of neonatal inherited metabolic diseases. Methods Data pertaining to screening of neonatal inherited metabolic disease in Chaoyang District from 2012 to 2021 were captured from Beijing Center for Neonatal Disease Screening. The percentage of screening, eligible rate of blood smears collection, re-examination rate of suspected cases, and definitive diagnosis of congenital hypothyroidism (CH), phenylketonuria (PKU) and congenital adrenal hyperplasia (CAH) were analyzed to evaluate the quality of neonatal inherited metabolic diseases screening in Chaoyang District. Results There were 484 002 live neonates in Chaoyang District from 2012 to 2021, and 481 395 neonates were screened for inherited metabolic diseases, with a screening rate of 99.46% and 99.71% eligible rate of blood smears collection. A total of 4 305 suspected positive cases were screened, including 4 148 cases recalled for re-examinations, with a 96.35% re-examination rate of suspected cases, and the re-examination rates of CH, PKU and CAH were 96.37%, 96.79% and 95.65%, respectively. Totally 482 neonates were definitively diagnosed with inherited metabolic diseases, with an overall incidence rate of 1/999, and the incidence rates of CH (307 cases), hyperthyrotropinemia (103 cases), PKU (66 cases) and CAH (6 cases) were 1/1 568, 1/4 674, 1/7 294 and 1/20 233, respectively. Conclusions The screening rate and re-examination rate of neonatal inherited metabolic diseases was both more than 95% in Chaoyang District from 2012 to 2021. Improving the management of neonatal inherited metabolic diseases screening and the recall of suspected cases is required.
