Data quality methods through remote source data verification auditing: results from the Congenital Cardiac Research Collaborative.

BACKGROUND: Multicentre research databases can provide insights into healthcare processes to improve outcomes and make practice recommendations for novel approaches. Effective audits can establish a framework for reporting research efforts, ensuring accurate reporting, and spearheading quality improvement. Although a variety of data auditing models and standards exist, barriers to effective auditing including costs, regulatory requirements, travel, and design complexity must be considered. MATERIALS AND METHODS: The Congenital Cardiac Research Collaborative conducted a virtual data training initiative and remote source data verification audit on a retrospective multicentre dataset. CCRC investigators across nine institutions were trained to extract and enter data into a robust dataset on patients with tetralogy of Fallot who required neonatal intervention. Centres provided de-identified source files for a randomised 10% patient sample audit. Key auditing variables, discrepancy types, and severity levels were analysed across two study groups, primary repair and staged repair. RESULTS: Of the total 572 study patients, data from 58 patients (31 staged repairs and 27 primary repairs) were source data verified. Amongst the 1790 variables audited, 45 discrepancies were discovered, resulting in an overall accuracy rate of 97.5%. High accuracy rates were consistent across all CCRC institutions ranging from 94.6% to 99.4% and were reported for both minor (1.5%) and major discrepancies type classifications (1.1%). CONCLUSION: Findings indicate that implementing a virtual multicentre training initiative and remote source data verification audit can identify data quality concerns and produce a reliable, high-quality dataset. Remote auditing capacity is especially important during the current COVID-19 pandemic.

Treatment of attention deficit/hyperactivity disorder in children with CHD.

INTRODUCTION: The prevalence of attention deficit/hyperactivity disorder in the general population is common and is now diagnosed in 4%-12% of children. Children with CHD have been shown to be at increased risk for attention deficit/hyperactivity disorder. Case reports have led to concern regarding the use of attention deficit/hyperactivity disorder medications in children with underlying CHD. We hypothesised that medical therapy for patients with CHD and attention deficit/hyperactivity disorder is safe. METHODS: A single-centre, retrospective chart review was performed evaluating for adverse events in patients aged 4-21 years with CHD who received attention deficit/hyperactivity disorder therapy over a 5-year span. Inclusion criteria were a diagnosis of CHD and concomitant medical therapy with amphetamines, methylphenidate, or atomoxetine. Patients with trivial or spontaneously resolved CHD were excluded from analysis. RESULTS: In 831 patients with CHD who received stimulants with a mean age of 12.9 years, there was only one adverse cardiovascular event identified. Using sensitivity analysis, our median follow-up time was 686 days and a prevalence rate of 0.21% of adverse events. This episode consisted of increased frequency of supraventricular tachycardia in a patient who had this condition prior to initiation of medical therapy; the condition improved with discontinuation of attention deficit/hyperactivity disorder therapy. CONCLUSION: The incidence of significant adverse cardiovascular events in our population was similar to the prevalence of supraventricular tachycardia in the general population. Our single-centre experience demonstrated no increased risk in adverse events related to medical therapy for children with attention deficit/hyperactivity disorder and underlying CHD. Further population-based studies are indicated to validate these findings.

Accuracy of subjective vesicoureteral reflux timing assessment: supporting new voiding cystourethrogram guidelines.

BACKGROUND: Bladder volume at the onset of vesicoureteral reflux (VUR) is an important prognostic indicator of spontaneous resolution and the risk of pyelonephritis. OBJECTIVE: We aim to determine whether pediatric urologists and pediatric radiologists can accurately estimate the timing of reflux by examining voiding cystourethrogram (VCUG) images without prior knowledge of the instilled contrast volume. MATERIALS AND METHODS: Total bladder volume and the volume at the time of reflux were collected from VCUG reports to determine the volume at the onset of VUR. Thirty-nine patients were sorted into three groups: early-/mid-filling reflux, late-filling and voiding only. Thirty-nine images were shown to three pediatric urologists and two pediatric radiologists in a blinded fashion and they were then asked to estimate VUR timing based on the above categories. A weighted kappa statistic was calculated to assess rater agreement with the gold standard volume-based report of VUR timing. RESULTS: The mean patient age at VCUG was 3.1±2.9 months, the median VUR was grade 3, and 20 patients were female. Overall agreement among all five raters was moderate (k=0.43, 95% confidence interval [CI] 0.36-0.50). Individual agreement between rater and gold standard was slight to moderate with kappa values ranging from 0.13 to 0.43. CONCLUSION: Pediatric radiologists and urologists are unable to accurately and reliably characterize VUR timing on fluoroscopic VCUG. These findings support the recently published American Academy of Pediatrics protocol recommending the routine recording of bladder volume at the onset of VUR as a standard component of all VCUGs to assist in a more accurate assessment of the likelihood of resolution and risk of recurrent urinary tract infections.

Radiologic Imaging in Trauma Patients with Cervical Spine Immobilization at a Pediatric Trauma Center.

BACKGROUND: Pediatric trauma patients with cervical spine (CS) immobilization using a cervical collar often require procedural sedation (PS) for radiologic imaging. The limited ability to perform airway maneuvers while CS immobilized with a cervical collar is a concern for emergency department (ED) staff providing PS. OBJECTIVE: To describe the use of PS and analgesia for radiologic imaging acquisition in pediatric trauma patients with CS immobilization. METHODS: Retrospective medical record review of all trauma patients with CS immobilization at a high-volume pediatric trauma center was performed. Patient demographics, imaging modality, PS success, sedative and analgesia medications, and adverse events were analyzed. Patients intubated prior to arrival to the ED were excluded. RESULTS: A total of 1417 patients with 1898 imaging encounters met our inclusion criteria. A total of 398 patients required more than one radiographic imaging procedure. The median age was 8 years (range 3.8-12.75 years). Computed tomography of the head was used in 974 of the 1898 patients (51.3%). A total of 956 of the 1898 patients (50.4%) required sedatives or analgesics for their radiographic imaging, with 875 (91.5%) requiring a single sedative or analgesic agent, and 81 (8.5%) requiring more than one medication. Airway obstruction was the most common adverse event, occurring in 5 of 956 patients (0.3%). All imaging procedures were successfully completed. CONCLUSION: Only 50% of CS immobilized, nonintubated patients required a single sedative or analgesic medication for their radiologic imaging. Procedural success was high, with few adverse events.
