Identification of Critical Congenital Heart Disease in Vermont: The Role of Universal Pulse Oximetry Screening in a Rural State.

OBJECTIVE: Pulse oximetry screening (POS) is becoming the standard of care in screening for critical congenital heart disease (CCHD). Our objective was to characterize the historical diagnostic pattern in a rural tertiary care children's hospital and explore how universal POS might affect morbidity, mortality, and care delivery. PATIENTS AND METHODS: We identified patients <6 months of age in the Vermont Children's Hospital echocardiogram database with CCHD diagnosed between 2002 and 2011. Charts were reviewed to characterize timing of diagnosis, course, and outcome. The medical examiner was consulted to identify deaths due to undetected CCHD during the study period. RESULTS: Of 60 329 live births, 73 (0.12 %) were diagnosed with CCHD. Of these, 31 (42%) were diagnosed prenatally, 34 (47%) were diagnosed by clinical examination in the nursery, 7 (9.6%) were diagnosed after nursery discharge, and 1 (1.4%) was born at home. The 8 patients not diagnosed by prenatal ultrasound or in the nursery were considered cases of undetected CCHD. Three had normal oxygen saturation (>95%) at diagnosis. Three presented with cardiovascular compromise. None died and all were well at the most recent follow-up. Review of autopsy reports from patients <6 months found no deaths from undetected CCHD during the study period. CONCLUSIONS: Over a 10-year period at our institution, universal POS could have identified 5 patients with undetected CCHD, possibly avoiding the need for resuscitation in 3. Examination of local diagnostic data may affect the cost/benefit considerations of universal POS initiatives in a setting of limited healthcare resources.

Dual growing rod technique followed for three to eleven years until final fusion: the effect of frequency of lengthening.

STUDY DESIGN: Retrospective case review of children completing dual growing rod treatment at our institutions. Patients had a minimum of 2 years follow-up. OBJECTIVE: To identify the factors influencing dual growing rod treatment outcome followed to final fusion. SUMMARY OF BACKGROUND DATA: Published reports on dual growing rod technique results for early onset scoliosis demonstrate it to be safe and effective in curve correction and maintenance as well as in allowing spinal growth. METHODS: Between 1990 and 2003, 13 patients with no previous surgery and noncongenital curves underwent final fusion. All had preoperative curve progression over 10 degrees after unsuccessful nonoperative treatment. There were 10 females and 3 males. Average age was 6.6 +/- 2.9 years at initial surgery. There were 3 idiopathic, 1 nonspine congenital anomaly, and 9 syndromic patients. Analysis included age at initial surgery and final fusion, number and frequency of lengthenings, and complications. Radiographic evaluation included changes in Cobb angle, T1-S1 length, and instrumentation length over the treatment period. RESULTS: Cobb angle improved from 81.0 +/- 23 degrees to 35.8 +/- 15 degrees postinitial and 27.7 +/- 17 degrees after final fusion. Average number of lengthenings was 5.2 +/- 3 at an interval of 9.4 +/- 5 months. T1-S1 length increased from 24.4 +/- 3.4 to 29.3 +/- 3.6 cm postinitial and 35.0 +/- 3.7 cm postfinal fusion. Average growth was 1.46 +/- 0.66 cm/year. Those lengthened at
