PURPOSE/OBJECTIVE:The current loss to follow-up rate after failed newborn hearing screening (NBHS) is 34.4%. Previous studies have found that lack of parental and primary care provider (PCP) awareness of NBHS results are significant contributors to loss to follow-up. The objective of this study was to identify factors associated with parental and PCP awareness of NBHS results. MATERIALS AND METHODS/METHODS:Retrospective cohort study. A survey asking about demographics and knowledge of NBHS testing and results was offered to parents in the waiting room of an urban pediatric primary care office. Included were biological parents ≥18 years of age of children ≤10 years of age born in Pennsylvania. Each child's chart was reviewed for PCP documentation of NBHS results. The odds of knowing NBHS results were evaluated using logistic regression. RESULTS:The survey was completed by 304 parents. 74.0% were aware of their child's NBHS results. Child age ≥1 year old (OR: 0.49, 95%CI[0.29, 0.82], P = 0.007) and Hispanic ethnicity (OR: 0.38, 95%CI[0.16, 0.89], P = 0.03) were associated with decreased odds of a parent knowing NBHS results. In addition, fewer fathers knew the results of their child's NBHS compared with mothers (OR: 0.33, 95%CI[0.18, 0.62], P < 0.001). However, parental awareness was not associated with birthing facility or insurance type. 222 charts were reviewed for NBHS documentation, revealing PCP awareness in 95.5% of cases and no associations with any of the factors examined. CONCLUSIONS:Factors associated with parents not knowing NBHS results included being the parent of an older child, Hispanic, or the father.

OBJECTIVE:Routine plain film radiographs are often obtained to confirm proper placement of electrode after pediatric cochlear implant surgery. Objective is to evaluate necessity of routine radiographs in pediatric cochlear implant cases. STUDY DESIGN/METHODS:Retrospective review. SETTING/METHODS:Two tertiary care academic centers. SUBJECTS AND METHODS/METHODS:Review of all children that underwent cochlear implantation from January 2003 thru June 2015. Exclusions include patients without intraoperative evoked compound action potential (ECAP) data or radiographs and patients undergoing revision surgeries. RESULTS:235 pediatric patients underwent 371 cochlear implants. ECAP measurements were not available in two cases and were excluded from study. Radiographs were obtained in 35/369 cases due to intraoperative concern and four had abnormal findings. All four cases underwent change in management. One other patient had an x-ray because of difficult insertion and abnormal ECAP. Radiograph was normal; however, incision was opened and electrodes inserted further. Overall, 5/369 cases had changes in management intraoperatively. In all five cases, abnormalities were suspected by clinician judgment or abnormal ECAP measurements. Routine radiographs were completed in 349/369 cases and one was abnormal. This patient had known partial insertion due to cochlear fibrosis from meningitis and abnormal radiograph did not result in change in management. CONCLUSION/CONCLUSIONS:Clinician suspicion and/or abnormal ECAP prompted suspicion for abnormal electrode placement prior to evaluation with radiograph in all cases in which change in management occurred. Intraoperative radiographs may be valuable in setting of clinical suspicion. Routine radiographs do not result in change in management and are, therefore, unnecessary.
