Abstract
Objective: To determine the impact of a referral protocol for very low birth weight (VLBW) infants and document the incidence rate of late onset hearing loss.
Study design: Retrospective study (2003-2015) of post-discharge hearing outcomes and risk factors in the VLBW infant population, before and after the institution of a standardized follow-up program. Risk factors were compared between cases and matched controls.
Results: Late onset hearing loss detection increased from 2.2 per 100 VLBW infants to 6.9 per 100 post standardization. The follow-up compliance rate nearly doubled. The age at diagnosis decreased from 31 to 12 months postnatal age. The detection of conductive loss increased four-fold, while sensorineural hearing loss remained unchanged.
Conclusion: A significant proportion late onset hearing loss in VLBW infants is conductive, which can negatively impact speech and language development. A standardized process is essential for early detection and optimal outcomes.
期刊介绍：
The Journal of Perinatology provides members of the perinatal/neonatal healthcare team with original information pertinent to improving maternal/fetal and neonatal care. We publish peer-reviewed clinical research articles, state-of-the art reviews, comments, quality improvement reports, and letters to the editor. Articles published in the Journal of Perinatology embrace the full scope of the specialty, including clinical, professional, political, administrative and educational aspects. The Journal also explores legal and ethical issues, neonatal technology and product development.
The Journal’s audience includes all those that participate in perinatal/neonatal care, including, but not limited to neonatologists, perinatologists, perinatal epidemiologists, pediatricians and pediatric subspecialists, surgeons, neonatal and perinatal nurses, respiratory therapists, pharmacists, social workers, dieticians, speech and hearing experts, other allied health professionals, as well as subspecialists who participate in patient care including radiologists, laboratory medicine and pathologists.
