Association of Interstage Home Monitoring With Mortality, Readmissions, and Weight Gain A Multicenter Study from the National Pediatric Cardiology Quality Improvement Collaborative

Background— Daily home monitoring of oxygen saturation and weight has been reported to improve outcomes for patients with single-ventricle heart disease during the period between stage I palliation and stage II palliation. However, these studies have been limited to single institutions and used historical control subjects. Our objective was to determine the association of various interstage home monitoring strategies with outcomes using a multicenter cohort with contemporary control subjects. Methods and Results— We performed a retrospective cohort study using prospectively collected data from the National Pediatric Cardiology Quality Improvement Collaborative from 2008 to 2012. We compared interstage mortality, unscheduled readmissions, and change in weight-for-age Z score for various home monitoring strategies of oxygen saturation (n=494) or weight (n=472), adjusting for sex, syndrome, tricuspid regurgitation, arch obstruction, and shunt type. Overall interstage mortality was 8.1%, and 47% had ≥1 unscheduled readmission. We did not find any associations of home oxygen saturation or weight monitoring with mortality or readmission. Although there was no difference in weight-for-age Z score for daily (0.33±0.12) versus weekly (0.34±0.18, P=0.98) weight monitoring, daily home weight monitoring was superior to no home weight monitoring (−0.15±0.18; P<0.01). Conclusions— Home weight monitoring is associated with improved weight gain during the interstage period, but we did not find any benefits in other clinical outcomes for either home oxygen saturation monitoring or home weight monitoring.

Transcatheter Versus Surgical Closure of Atrial Septal Defects in Children: A Value Comparison.

OBJECTIVES The purpose of this study was to determine whether a transcatheter procedure or surgical closure offers a better value proposition for atrial septal defect (ASD) closure. BACKGROUND Secundum ASDs are common congenital heart defects with both transcatheter and surgical treatment options. Although both options have been shown to have excellent results in children, the relative value of the 2 procedures is unclear. METHODS Using data from the Pediatric Hospital Information System for 2004 to 2012, we compared the value of transcatheter versus surgical ASD closure for children ages 1 to 17 years, with value being defined as outcomes relative to costs. Total charges for procedure-related encounters were converted to costs using hospital-specific cost-to-charge ratios, and all costs were adjusted for inflation to reflect 2012 dollars. RESULTS There were 4,606 transcatheter procedures and 3,159 surgeries at 35 childrens hospitals. Those undergoing transcatheter closure were more likely to be older (5.6 years vs. 4.5 years, p < 0.0001). There was no mortality in either group. Children with a surgical procedure had a longer length of stay (4.0 days vs. 1.5 days, p < 0.0001), were more likely to have an infection (odds ratio: 3.73, p < 0.0001) or procedural complication (odds ratio: 6.66, p < 0.0001). Costs for transcatheter procedure encounters were lower than costs for surgical encounters (mean of

25,359, p < 0.0001). CONCLUSIONS Both transcatheter and surgical ASD closure had excellent short-term outcomes, but transcatheter procedures had lower lengths of stay, rates of infection, and complications, resulting in lower overall costs. For children who are eligible, transcatheter ASD closure provides better short-term value than surgery.

Association of Interstage Home Monitoring With Mortality, Readmissions, and Weight Gain

Secundum atrial septal defects (ASDs) are common congenital heart defects with both transcatheter and surgical treatment options. While both options have been shown to have excellent results in children, the relative value of the two procedures is unknown. The purpose of this study was to determine

Association of Interstage Home Monitoring With Mortality, Readmissions, and Weight GainCLINICAL PERSPECTIVE

BACKGROUND It is unclear whether cryoablation or radiofrequency ablation offers better value for treating atrioventricular nodal re-entrant tachycardia in children. We aimed to compare the value of these procedures for treating atrioventricular nodal re-entrant tachycardia in children, with value being outcomes relative to costs. METHODS We performed a retrospective cohort study of all atrioventricular nodal re-entrant tachycardia ablations for children (age⩽18 years) from July, 2009 to June, 2011 at our institution. Costs included fixed costs, miscellaneous hospital costs, and labour costs, and key outcomes were acute and long-term success (6 months) of the ablations. We conducted T-tests and regression analyses to investigate the associations between the ablation procedure type and the cost and success of the ablations. RESULTS Of 96 unique cases performed by three paediatric electrophysiologists, 48 were cryoablation only, 42 radiofrequency ablation only, and six were a combination. Acute success was 100% for the cryoablation only and radiofrequency ablation only cases and 83% for the combination cases. There were no notable adverse events. The average total cost was

10,967 for combination cases (p=0.51 for cryoablation only versus radiofrequency ablation only). The long-term success rate was 79.1% for cryoablation only, 92.8% for radiofrequency ablation only, and 66.7% for the combination (p=0.01 for cryoablation only versus radiofrequency ablation only), but long-term success varied notably by provider. CONCLUSIONS Cryoablation and radiofrequency ablation offer similar value in the short term for the treatment of atrioventricular nodal re-entrant tachycardia in children. Differences in long-term success may vary substantially by physician, and thus may lead to differences in long-term value.
