Minimum Travel Distance Among Publicly Insured Infants with Severe Congenital Heart Disease: Potential Impact of In-state Restrictions

Child Opportunity Index and Pediatric Extracorporeal Membrane Oxygenation Outcomes; the Role of Diagnostic Category

OBJECTIVES

To study the impact of social determinants of health (SDoH) on pediatric extracorporeal membrane oxygenation (ECMO) outcomes.

DESIGN, SETTING, AND PATIENTS

Retrospective study of children (< 18 yr) supported on ECMO (October 1, 2015 to March 1, 2021) using Pediatric Health Information System (44 U.S. children's hospitals). Patients were divided into five diagnostic categories: neonatal cardiac, pediatric cardiac, neonatal respiratory, pediatric respiratory, and sepsis. SDoH included the Child Opportunity Index (COI; higher indicates social advantage), race, ethnicity, payer, and U.S. region. Children without COI were excluded. Diagnostic category-specific clinical variables related to baseline health and illness severity were collected.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Children supported on ECMO experienced a 33% in-hospital mortality (2863/8710). Overall, children with lower COI, "other" race, Hispanic ethnicity, public insurance and from South or West regions had greater mortality. Associations between SDoH and ECMO outcomes differed between diagnostic cohorts. Bivariate analyses found that only pediatric cardiac patients had an association between COI or race and mortality. Multivariable logistic regression analyses examined relationships between SDoH, clinical variables and mortality within diagnostic categories. Pediatric cardiac patients had 5% increased odds of death (95% CI, 1.01-1.09) for every 10-point decrement in COI, while Hispanic ethnicity was associated with higher survival (adjusted odds ratio [aOR] 0.72 [0.57-0.89]). Children with heart disease from the highest COI quintile had less cardiac-surgical complexity and earlier cannulation. Independent associations with mortality were observed in sepsis for Black race (aOR 1.62 [1.06-2.47]) and other payer in pediatric respiratory patients (aOR 1.94 [1.23-3.06]).

CONCLUSIONS

SDoH are statistically associated with pediatric ECMO outcomes; however, associations differ between diagnostic categories. Influence of COI was observed only in cardiac patients while payer, race, and ethnicity results varied. Further research should investigate differences between diagnostic cohorts and age groups to understand drivers of inequitable outcomes.

Child Health Needs and the Pediatric Cardiology Workforce: 2020-2040

This article evaluates the pediatric cardiology (PC) workforce and forecasts its future supply. Produced as part of a supplement in Pediatrics, this effort represents a collaboration among the American Board of Pediatrics Foundation, the University of North Carolina at Chapel Hill's Carolina Health Workforce Research Center, the Strategic Modeling and Analysis Ltd., and members of the pediatric subspecialty community. PC is a complex subspecialty including care from fetal life through adulthood and in practice settings that range from the outpatient clinic to procedural settings to the cardiac ICU. Complex subdisciplines include imaging, electrophysiology, heart failure, and interventional and critical care. Using American Board of Pediatrics data, US Census Bureau data, and data from the modeling project, projections were created to model the subspecialty workforce through 2040. Across all modeling scenarios considered, there is considerable projected growth in the supply of pediatric cardiologists by 2040. However, there is significant regional variation in the projected supply of trainees relative to demand in terms of local population growth, with evidence of a likely mismatch between areas surrounding training centers versus areas of greatest workforce need. In addition, this article highlights areas for future focus, including efforts to attract more residents to the subspecialty in general, particularly underrepresented minority members; increased support, more part-time career options, and improved academic career advancement for women in PC; and the development of better "real-time" workforce data to guide trainees and training programs in decisions regarding sub-subspecialty job availability.

Association Between Prenatal Diagnosis and Age at Surgery for Noncritical and Critical Congenital Heart Defects

BACKGROUND

The relationship between the prenatal diagnosis of congenital heart defects (CHDs) and age at CHD surgery is poorly understood, despite the known relationships between age at surgery and long-term outcomes. The objective of this study was to determine the associations between prenatal diagnosis of CHD and age at surgery, and whether these associations differ for critical and noncritical CHDs.

METHODS

This is a cohort analysis of patients aged 0 to 9 years who received their initial cardiac surgery at Ann & Robert H. Lurie Children's Hospital of Chicago between 2015 and 2021 with prenatal diagnosis as the exposure variable. All data were obtained from the locally maintained Society of Thoracic Surgeons Congenital Heart Surgery Database at Lurie Children's Hospital. We used multivariable fixed effects regression models to estimate the strength of the association of prenatal diagnosis with age at surgery among patients with critical (surgery ≤60 days) and noncritical (surgery >60 days) CHDs.

RESULTS

Of 1131 individuals who met inclusion criteria, 532 (47%) had a prenatal diagnosis, 428 (38%) had critical CHDs, 533 (47%) were female, and the median age at surgery was 119 days (interquartile range, 11-309 days). After controlling for demographics, comorbidities, and surgical complexity, the mean age at surgery was significantly younger in those with prenatally versus postnatally diagnosed critical CHD (7.1 days sooner, P<0.001) and noncritical CHDs (atrial septal defects [12.4 months sooner, P=0.037], ventricular septal defects [6.0 months sooner, P<0.003], and noncritical coarctation of the aorta [1.8 months sooner, P=0.010]).

CONCLUSIONS

Younger age at CHD surgery, which is associated with postsurgical neurodevelopmental and physical outcomes, is significantly associated with prenatal CHD diagnosis. This relationship was identified for both critical and noncritical CHDs.

The effect of geographic origin and destination on congenital heart disease outcomes: a retrospective cohort study

BACKGROUND

Congenital heart disease (CHD) is a common and significant birth defect, frequently requiring surgical intervention. For beneficiaries of the Department of Defense, a new diagnosis of CHD may occur while living at rural duty stations. Choice of tertiary care center becomes a function of geography, referring provider recommendations, and patient preference.

METHODS

Using billing data from the Military Health System over a 5-year period, outcomes for beneficiaries age < 10 years undergoing CHD surgery were compared by patient origin (rural versus urban residence) and the distance to treatment (patient's home and the treating tertiary care center). These beneficiaries include children of active duty, activated reserves, and federally activated National Guard service members. Analysis of the outcomes were adjusted for procedure complexity risk. Treatment centers were further stratified by annual case volume and whether they publicly reported results in the society of thoracic surgery (STS) outcomes database.

RESULTS

While increasing distance was associated with the cost of admission, there was no associated risk of inpatient mortality, one year mortality, or increased length of stay. Likewise, rural origination was not significantly associated with target outcomes. Patients traveled farther for STS-reporting centers (STS-pr), particularly high-volume centers. Such high-volume centers (> 50 high complexity cases annually) demonstrated decreased one year mortality, but increased cost and length of stay.

CONCLUSIONS

Together, these findings contribute to the national conversation of rural community medicine versus regionalized subspecialty care; separation of patients between rural areas and more urban locations for initial CHD surgical care does not increase their mortality risk. In fact, traveling to high volume centers may have an associated mortality benefit.

Geographic access to care and pediatric surgical outcomes

INTRODUCTION

Rurality and distance traveled for healthcare are associated with worse pediatric health indicators.

METHODS

We retrospectively analyzed patients ages 0-21 at a quaternary pediatric surgical facility with a large rural catchment area between 1/1/2016-12/31/2020. Patient addresses were designated as metropolitan or non-metropolitan. 60- and 120-min driving rings from our institution were calculated. Logistic regression assessed the effect of rurality and distance traveled for care on postoperative mortality and serious adverse events (SAE).

RESULTS

Among 56,655 patients, 84.3% were from metropolitan areas, 8.4% from non-metropolitan areas, and 7.3% could not be geocoded. 64% were within 60-min driving and 80% within 120-min. On univariable regression, patients living >120-min experienced 59% (95% CI: 1.09, 2.30) increased odds of mortality and 97% (95% CI: 1.84, 2.12) increased odds of SAE compared to those <60-min. Non-metropolitan patients experienced 38% (95% CI: 1.26, 1.52) increased odds of a serious postoperative event compared to metropolitan patients.

DISCUSSION

Efforts to improve geographic access to pediatric care are needed to mitigate the impact of rurality and travel time on inequitable surgical outcomes.

Hocus POCUS! Parental Quantification of Left-Ventricular Ejection Fraction Using Point of Care Ultrasound: Fiction or Reality?

Point of care ultrasound has become increasingly utilized in pediatric settings. The assessment of cardiac function is one such implementation of this. This study aimed to determine the feasibility of parents in acquiring images to assess function using a handheld ultrasound probe and the correlation of fractional shortening measurements by handheld ultrasound with hospital acquired echocardiography. This was a single-center prospective study of parents of pediatric patients admitted to the hospital. Parents underwent a 25-min education session on how to use the handheld ultrasound probe and then were asked to acquire a parasternal short-axis and apical four-chamber image on their own. Acquired images were reviewed by two physicians to determine adequacy of images to assess systolic cardiac function subjectively and objectively. Fractional shortening was measured using parent-acquired images and then compared to recent hospital acquired fractional shortening. A total of 25 parents of 21 patients enrolled and completed the study. Of the enrolled parents, 96% of both parasternal short-axis and apical four-chamber images acquired were deemed appropriate for subjective assessment of systolic function. Inter-reader variability of fractional shortening was moderate between two readers. Correlation of fractional shortening measured from parent-acquired images versus hospital acquired images was moderate. Parents were able to successfully obtain a parasternal short-axis and apical four-chamber image adequate to assess function and quantify fractional shortening after a 25-min education session. This pilot data demonstrate that further exploration of parent-performed point of care cardiac assessment may be warranted.

Addressing Social Determinants of Health and Mitigating Health Disparities Across the Lifespan in Congenital Heart Disease: A Scientific Statement From the American Heart Association

Despite the overall improvement in life expectancy of patients living with congenital heart disease (congenital HD), disparities in morbidity and mortality remain throughout the lifespan. Longstanding systemic inequities, disparities in the social determinants of health, and the inability to obtain quality lifelong care contribute to poorer outcomes. To work toward health equity in populations with congenital HD, we must recognize the existence and strategize the elimination of inequities in overall congenital HD morbidity and mortality, disparate health care access, and overall quality of health services in the context of varying social determinants of health, systemic inequities, and structural racism. This requires critically examining multilevel contributions that continue to facilitate health inequities in the natural history and consequences of congenital HD. In this scientific statement, we focus on population, systemic, institutional, and individual‐level contributions to health inequities from prenatal to adult congenital HD care. We review opportunities and strategies for improvement in lifelong congenital HD care based on current public health and scientific evidence, surgical data, experiences from other patient populations, and recognition of implicit bias and microaggressions. Furthermore, we review directions and goals for both quantitative and qualitative research approaches to understanding and mitigating health inequities in congenital HD care. Finally, we assess ways to improve the diversity of the congenital HD workforce as well as ethical guidance on addressing social determinants of health in the context of clinical care and research.

Health and Poverty of Rural Children: An Under-Researched and Under-Resourced Vulnerable Population

Nearly 1 in 5 children in the United States live in rural areas. Rural children experience health and health care disparities compared to their urban peers and represent a unique and vulnerable pediatric patient population. Important disparities exist in all-cause mortality, suicide, firearm-related unintentional injury, and obesity. Rural children experience decreased availability and accessibility of primary care and specialty care (especially mental health care) due to a decreased number of health care providers as well as geographical and transportation-related barriers. Other geographic and socioeconomic determinants, especially concerning poverty and substandard housing conditions, are likely important contributors to the observed health disparities. Increased funding for research focused on rural populations is needed to provide innovative solutions for the unique health needs of rural children. Policy changes positioned to correct the trajectory of poor health among children should consider the needs of rural children as an under-researched and under-resourced vulnerable population.

Back Transfer of Infants with Tracheostomies: A Regional Center Experience

We describe our center's experience with the back transfer of infants following tracheostomies. We conducted a retrospective cohort study of infants transferred to pediatric critical care units of our regional center with conditions originating in the neonatal period who underwent tracheostomy during the hospitalization within their first year of life between 2006 and 2017. Recovering patients are discharged home or transferred back to the referring hospitals. We evaluated patient characteristics, destination of discharge and type of pulmonary support at discharge, and mechanical ventilation (MV) or tracheotomy masks (TM). Of the 139 included patients, 72% were transferred to the neonatal intensive care unit, 21% to the pediatric cardiothoracic unit, and 7% to the pediatric intensive care unit. Their median gestational age was 35 weeks. They were admitted at a median 22 days of life and lived at a median distance of 56 miles from our center. Furthermore, 34 infants (24%) were back transferred closer to their homes (23 with MV and 11 with TM), and 84 (60%) were discharged home (53 on MV and 31 on TM). Twenty-one patients (15%) died in the hospital (before discharge or transfer). Back transferred patients on MV had a significantly shorter duration between tracheostomy and transfer compared with those discharged home from our center: MV (median = 22 vs. 103 days, p < 0.0001) and TM (median = 13 vs. 35 days, p < 0.0001). Back transfer of infants with tracheostomies closer to their homes was associated with a significantly shorter hospitalization and more efficient use of the subspecialized resources at the RC.

Social determinants of health and outcomes for children and adults with congenital heart disease: a systematic review

BACKGROUND

Social determinants of health (SDH) can substantially impact health outcomes. A systematic review, however, has never been conducted on associations of SDH with congenital heart disease (CHD) outcomes. The aim, therefore, was to conduct such a systematic review.

METHODS

Seven databases were searched through May 2020 to identify articles on SDH associations with CHD. SDH examined included poverty, uninsurance, housing instability, parental educational attainment, immigration status, food insecurity, and transportation barriers. Studies were independently selected and coded by two researchers based on the PICO statement.

RESULTS

The search generated 3992 citations; 88 were included in the final database. SDH were significantly associated with a lower likelihood of fetal CHD diagnosis, higher CHD incidence and prevalence, increased infant mortality, adverse post-surgical outcomes (including hospital readmission and death), decreased healthcare access (including missed appointments, no shows, and loss to follow-up), impaired neurodevelopmental outcomes (including IQ and school performance) and quality of life, and adverse outcomes for adults with CHD (including endocarditis, hospitalization, and death).

CONCLUSIONS

SDH are associated with a wide range of adverse outcomes for fetuses, children, and adults with CHD. SDH screening and referral to appropriate services has the potential to improve outcomes for CHD patients across the lifespan.

IMPACT

Social determinants of health (SDH) are associated with a wide range of adverse outcomes for fetuses, children, and adults with congenital heart disease (CHD). This is the first systematic review (to our knowledge) on associations of SDH with congenital heart disease CHD outcomes. SDH screening and referral to appropriate services has the potential to improve outcomes for CHD patients across the lifespan.
