Follow-up after a failed newborn hearing screen: a quality improvement study.

OBJECTIVE: Universal newborn hearing screening (UNHS) has been implemented for several decades to screen for congenital hearing loss; however, the lost to follow-up (LFU) rate for newborns with a failed screen is nearly 50%. Many studies have examined risk factors rendering infants susceptible to being LFU, but there are no quality improvement studies using evidence-based practice that aim to improve follow-up rates. This study utilized a nurse practitioner (NP) to provide a teaching intervention to educate parents on recommended follow-up after a failed hearing screen, including the Healthy People 2020 objectives. METHODS: Seventeen newborn/mother couplets were recruited to participate in a multi-site quality improvement project over a six week period prior to hospital discharge. At the bedside with the NP, mothers completed a demographic survey and were provided education on Georgia's UNHS Program and recommended follow-up based on the Healthy People 2020 objectives. An appointment with the hospital's audiologist was given to the mother in writing. A retrospective chart review was performed three months after the newborn's birth to document follow-up with audiology or to see if the infant was lost to follow-up for audiologic evaluation (LFUAE). RESULTS: Of the 17 newborns enrolled, 14 had adequate follow-up with audiology within three months of birth. Hospital A showed statistical significance with one newborn that was LFUAE when compared to the nation LFU rate (n=12, p=0.01). Prior to project intervention, Hospital B had a 70% LFUAE rate; however, its post intervention LFUAE rate decreased to 40% (n=5). Statistical significance was unable to be obtained due to small sample size. Two mothers reported smoking during pregnancy and both of their newborns were LFUAE. CONCLUSIONS: This project suggests that education by the NP prior to hospital discharge was statistically significant at Hospital A. Health care providers should actively engage in educating parents regarding expected follow-up guidelines and incorporating the Healthy People 2020 objectives. Further studies are needed that can also examine the six month follow-up with pediatric otolaryngology for hearing aid fitting and early intervention.

Battery swallow-induced tracheoesophageal fistula in a pediatric patient.

Tracheoesophageal fistula (TEF) is an abnormal connection between the trachea and esophagus. Rare acquired TEF arises from trauma, caustic fluids ingestion, and iatrogenic injuries (ventilation, esophageal atresia repair, radiation, or tracheal/esophageal stents). We discuss the diagnosis, anesthetic management, and surgical correction of battery swallow-induced TEF, not previously reported in the pediatric anesthesia and otorhinolaryngology literatures.

Prenatal ultrasound exposure and association with postnatal hearing outcomes.

OBJECTIVE: Prenatal ultrasound exams have become increasingly frequent. Although no serious adverse effects are known, the public health implications would be enormous should adverse effects on auditory development be shown. This study looks to establish a possible correlation between hearing loss and increased prenatal ultrasound exposure. DESIGN: Retrospective cohort analysis. SETTING: Tertiary academic referral center. METHODS: A retrospective review of 100 children undergoing newborn hearing screening was conducted. Extensive data collection was performed, and this data was analyzed for a potential correlation between failure of newborn hearing screening and increased prenatal ultrasound exposure, as well as for a potential correlation of other variables with hearing loss. MAIN OUTCOME MEASURES: Postnatal hearing outcomes. RESULTS: A higher number of both total and 3rd trimester ultrasound exams as well as a younger gestational age at birth were all found to be significantly associated with a higher likelihood of passing the newborn hearing screen (p<0.001 for each). No other factors were found to reach statistical significance. CONCLUSIONS: Our results show that there is no correlation between a higher level of prenatal ultrasound exposure and hearing loss. Indeed, infants who had more prenatal ultrasounds in the third trimester were more likely to pass their screening hearing exams. The finding that children receiving more prenatal ultrasounds have a higher likelihood of passing newborn hearing screens serves as an excellent reminder of the classic statistics rule that correlation does not imply causation.
