目的:探讨分析新生儿听力筛查中假阳性的发生率和干预措施。方法:采用瞬态耳声发射技术(TEOAE)对2007年1～12月在唐山市妇幼保健院产科出生的4439例新生儿进行听力普遍筛查。初筛时间为生后2天,未通过者42天复筛,两次均未通过者生后3个月行听力学综合评估,并跟踪随访。结果:初筛4439例,通过4278例,通过率96.37%,复筛161例,通过129例,进入诊断程序32例,最后确诊听力损失6例,发病率0.14%。初筛假阳性率2.91%,整个筛查程序假阳性率0.58%。结论:重视假阳性率的产生原因并积极避免,提高新生儿听力筛查的质控水平。
Objective: To analyze the incidence of false positives in newborn hearing screening and intervention measures. Methods: Transient Otoacoustic Emission (TEOAE) was used to screen 4439 newborn babies born in Tangshan Maternity and Child Health Hospital from January 2007 to December 2007. The screening time was 2 days after birth, those who failed to pass the screening for 42 days, the two who did not pass 3 months after birth to perform comprehensive audiological evaluation, and follow-up. Results: 4439 cases were initially screened, 4278 cases passed, 96.37% passed, 161 cases screened, and 129 cases entered the diagnostic procedure in 32 cases. The final hearing loss was confirmed in 6 cases and the incidence rate was 0.14%. The false positive rate of primary screening was 2.91%, the false positive rate of the whole screening procedure was 0.58%. Conclusion: Pay attention to the causes of false positive rate and avoid it actively, and improve the quality control of newborn hearing screening.
