The Association of the Childhood Opportunity Index on Pediatric Readmissions and Emergency Department Revisits

Examining Patient- and Community-Level Factors Associated with Pediatric Mental Healthcare Access Within a Patient Navigation Program

In 2021, national leaders in the United States declared a "national youth mental health crisis." Still, only 1-in-4 children receive adequate mental healthcare access. Patient Navigator Programs (PNPs) can improve children's referral-to-connection to mental health services. We examined patient- and community-level factors associated with pediatric mental healthcare access. Pediatric Support Services (PSS) is a PNP that triages mental and behavioral health referrals within a large health system in a southeastern state. This study analyzes PSS data from September 2017-March 2023 and Child Opportunity Index 2.0 state-normed zip-code level data to assess social drivers of health estimates. Structural equation modeling was conducted between patient- and community-level factors and connection to mental health services. Overall, 62.7% of children connected to mental health services since PSS' inception. Regardless of SDOH, as children get older, they are more likely to connect with mental health services (β = .053, SE = .010, p < .001). Children with greater number of referral needs are more likely to connect with mental health services (β = .034, SE = .011, p = .002). Further, children who live in communities with higher opportunity levels are more likely to connect with mental health services (β = .016, SE = .008, p = .040), suggesting that children who live in low-income communities experience more barriers to mental healthcare. Social drivers may inform referral practices and tiered navigation support for optimal mental healthcare access among children. Further research should demonstrate the effectiveness of PNPs integrated within healthcare and community-based settings.

Association Between the COI and Excess Health Care Utilization and Costs for ACSC

BACKGROUND AND OBJECTIVES

The authors of previous work have associated the Childhood Opportunity Index (COI) with increased hospitalizations for ambulatory care sensitive conditions (ACSC). The burden of this inequity on the health care system is unknown. We sought to understand health care resource expenditure in terms of excess hospitalizations, hospital days, and cost.

METHODS

We performed a retrospective cross-sectional study of the Pediatric Health Information Systems database, including inpatient hospitalizations between January 1, 2016 and December 31, 2022 for children <18 years of age. We compared ACSC hospitalizations, mortality, and cost across COI strata.

RESULTS

We identified 2 870 121 hospitalizations among 1 969 934 children, of which 44.5% (1 277 568/2 870 121) were for ACSCs. A total of 49.1% (331 083/674 548) of hospitalizations in the very low stratum were potentially preventable, compared with 39.7% (222 037/559 003) in the very high stratum (P < .001). After adjustment, lower COI was associated with higher odds of potentially preventable hospitalization (odds ratio 1.18, 95% confidence interval [CI] 1.17-1.19). Compared with the very high COI stratum, there were a total of 137 550 (95% CI 134 582-140 517) excess hospitalizations across all other strata, resulting in an excess cost of $1.3 billion (95% CI $1.28-1.35 billion). Compared with the very high COI stratum, there were 813 (95% CI 758-871) excess deaths, with >95% from the very low and low COI strata.

CONCLUSIONS

Children with lower neighborhood opportunity have increased risk of ACSC hospitalizations. The COI may identify communities in which targeted intervention could reduce health care utilization and costs.

Getting to the bottom of why children with spina bifida use the emergency department: A qualitative analysis of parent and stakeholder perspectives

BACKGROUND

Children with Spina Bifida (SB) have considerable healthcare utilization, including Emergency Department use (EDU). We aimed to elicit reasons for EDU using qualitative analysis of interviews with both patient-caregiver dyads and stakeholders.

METHODS

A cohort of children with SB followed at our institution between 2016 and 2020 was identified and patient and clinical characteristics abstracted. Purposeful sampling by age and degree of past EDU was performed. Semi-structured interviews of dyads were performed using iteratively revised interview guides. Spanish-language interviews were conducted by a native Spanish speaker and transcripts professionally translated. Supplemental interviews with stakeholders, namely knowledgeable healthcare professionals, were also conducted. A qualitative framework approach was used for analysis, including open followed by closed independent coding with calculation of inter-rater reliability. A final interpretation of coding reports assessing convergence, divergence, and variation in themes across participant characteristics.

RESULTS

116 families (4 Spanish-speaking) and 7 stakeholders were interviewed. Sampling yielded a heterogenous cohort for EDU (56% with 0-10, 44% with >10 visits) and age (25% 0-4, 44% 5-11, 31% > 11 years). IRR was optimal (κ = 0.9). Themes in perceived reasons for EDU were 1) desire for "one-stop-shop" care, 2) an emergent medical problem, 3) providers' instructions, 4) negative past healthcare experience, 5) intrinsic caregiver moderators, and 6) temporospatial influences. Themes 1, 2, and 5 predominated in dyads, whereas themes 6, 3, and 5 were most common in stakeholders. Stakeholders focused largely on negative institutional and patient characteristics. Among dyads only, theme #1 was disproportionately emphasized by Spanish-speaking patients.

DISCUSSION

Families desired access to coordinated expert care, testing and imaging. The ED offers this for children with SB, regardless of clinical acuity. This may be especially valued by families with inherent challenges to navigating the healthcare system. Negative experiences in community clinical settings, healthcare provider recommendations and intrinsic parental factors were themes that seemed to contribute to seeking this "one-stop-shop" type of care. Care coordination may reduce ED reliance, but themes for the interviews suggest a systems-based efforts should weave in the community care setting.

CONCLUSIONS

For both stakeholders and caregivers, the ED represented a valued form of immediate access to multispecialty, expert care and testing in the context of perceived lack of timely, coordinated outpatient care. This may be moderated by intrinsic caregiver factors and negative past experiences. Although stakeholders discussed ideas that fit into patient-caregiver themes, the also uniquely focused on systems-based and patient-caregiver limitations.

Lower opportunity ZIP code is associated with worse outcomes after listing in pediatric heart transplantation

BACKGROUND

The Child Opportunity Index (COI) comprehensively measures children's social determinants of health. We describe association between COI and outcomes after listing for heart transplantation.

METHODS

We conducted a retrospective review of the United Network for Organ Sharing (UNOS) database for U.S. children listed for heart transplant between 2012 and 2020. ZIP codes were utilized to assign COI. Primary outcome was survival from time of listing. Secondary outcomes included waitlist survival, 1-year post-transplant survival, and conditional 1-year post-transplant survival. Cox regression was performed adjusting for payor, age, race, diagnosis, and support at listing for all outcomes except waitlist survival, for which Fine-Gray competing risk analysis was performed.

RESULTS

Of 5,723 children listed, 109 were excluded due to missing ZIP codes. Race/ethnicity and payor were associated with COI (p < 0.001). Patients living in very low COI ZIP codes compared to all others had increased mortality from time of listing (HR 1.16, CI 1.03-1.32, p = 0.02) with 1-, 5-, and 9-year survival of 79.3% vs 82.2%, 66.5% vs 73.0%, and 53.6% vs 64.7% respectively, were more likely to be removed from the waitlist due to death or being too sick (subdistribution HR 1.26, 95% CI 1.10-1.42), and had increased mortality conditional on one-year post-transplant survival (HR 1.38, 1.09-1.74, p = 0.008) with 1-, 3-, and 5- year survival of 94.7% vs 97.3%, 87.0% vs 93.1%, and 78.6% vs 86.9%.

CONCLUSIONS

Children living in lower opportunity ZIP codes had poorer survival from time of listing, poorer waitlist survival, and poorer conditional one-year post-transplant survival.

The Childhood Opportunity Index's Association with Adverse Pregnancy and Newborn Outcomes in Nulliparous Persons

OBJECTIVE

 The objective of the study was to determine if using a novel measure of social determinants of health, the Childhood Opportunity Index (COI), at the time of delivery was associated with development of adverse pregnancy outcomes (APO) in nulliparous pregnant persons.

STUDY DESIGN

 Data were extracted from the 779 participants from a single nuMoM2b (Nulliparous Pregnancy Outcomes Study: monitoring mothers-to-be) study site, a prospective cohort study designed to identify contributors to APOs. Residential address information at delivery was linked to the location's COI. The overall composite and component scores in education, health and environmental, and socioeconomic indices were recorded. APOs of interest included preterm birth, hypertensive disorders of pregnancy, small for gestational age at birth, stillbirth, and gestational diabetes. Participant characteristics were compared by COI category and the association of COI with APOs was analyzed by logistic regression, controlling for age and self-reported race/ethnicity.

RESULTS

 The overall COI distribution was very low (45%), low (17%), moderate (10%), high (15%), and very high (13%). A total of 329 (43.5%) participants experienced at least one APO. Overall COI was associated with developing an APO (p = 0.02). Each component score was also associated with developing APOs and with race/ethnicity (p < 0.05). Compared with higher COI categories, an overall low or very low categorized location was independently associated with developing an APO (odds ratio: 1.636, 95% confidence interval: 1.16-2.31). Adjusting for gestational age at birth, those in lower COI areas had newborns with lower birth weight, birth length, and head circumference (estimate [95% confidence interval] birth weight: -0.0005 g [-0.0008 to -0.0001]; length: -0.065 cm [-0.124 to -0.0091]; head circumference: -0.123 cm [-0.208 to -0.045]). COI was not associated with other newborn outcomes.

CONCLUSION

 COI, a marker for social determinants of health, is independently associated with APOs. The COI may be a tool for risk stratification for pregnant people to help with APO-reducing strategies.

KEY POINTS

· The COI is a neighborhood-level marker for social determinants of health.. · The COI at time of delivery is associated with APO and newborn birth weight, length, and head circumference.. · The COI may be usable in pregnancy clinics to help identify resource needs to optimize outcomes for pregnant individuals and newborns..

The Child Opportunity Index 2.0 and Disparities in Pediatric Cardiorespiratory Fitness

OBJECTIVE

To evaluate the effect of neighborhood-level characteristics on cardiorespiratory fitness (CRF) via peak oxygen consumption (VO2peak) for healthy pediatric patients.

STUDY DESIGN

The institutional cardiopulmonary exercise testing (CPET) database was analyzed retrospectively. All patients aged ≤ 18 years without a diagnosis of cardiac disease and with a maximal effort CPET were included. Patients were divided into three self-identified racial categories: White, Black, and Latinx. The Child Opportunity Index (COI) 2.0 was used to analyze social determinants of health. CRF was evaluated based on COI quintiles and race. Assessment of the effect of COI on racial disparities in CRF was performed using ANCOVA.

RESULTS

A total of 1753 CPETs met inclusion criteria. The mean VO2peak was 42.1 ± 9.8 mL/kg/min. The VO2peak increased from 39.1 ± 9.6 mL/kg/min for patients in the very low opportunity cohort to 43.9 ± 9.4 mL/kg/min for patients in the very high opportunity cohort. White patients had higher percent predicted VO2peak compared with both Black and Latinx patients (P < .01 for both comparisons). The racial differences in CRF were no longer significant when adjusting for COI.

CONCLUSION

In a large pediatric cohort, COI was associated with CRF. Racial disparities in CRF are reduced when accounting for modifiable risk factors.

Childhood opportunity and appropriate use of child safety restraints in motor vehicle collisions

Objectives

Safety restraints reduce injuries from motor vehicle collisions (MVCs) but are often improperly applied or not used. The Childhood Opportunity Index (COI) reflects social determinants of health and its study in pediatric trauma is limited. We hypothesized that MVC patients from low-opportunity neighborhoods are less likely to be appropriately restrained.

Methods

A retrospective cross-sectional study was performed on children/adolescents ≤18 years old in MVCs between January 1, 2011 and December 31, 2021. Patients were identified from the Children's Hospital Los Angeles trauma registry. The outcome was safety restraint use (appropriately restrained, not appropriately restrained). COI levels by home zip codes were stratified as very low, low, moderate, high, and very high. Multivariable regression controlling for age identified factors associated with safety restraint use.

Results

Of 337 patients, 73.9% were appropriately restrained and 26.1% were not appropriately restrained. Compared with appropriately restrained patients, more not appropriately restrained patients were from low-COI (26.1% vs 20.9%), high-COI (14.8% vs 10.8%) and very high-COI (10.2% vs 3.6%) neighborhoods. Multivariable analysis demonstrated no significant associations in appropriate restraint use and COI. There was a non-significant trend that children/adolescents from moderate-COI neighborhoods were more likely than those from very low-COI neighborhoods to be appropriately restrained (OR=1.82, 95% CI 0.78, 4.28).

Conclusion

Injury prevention initiatives focused on safety restraints should target families of children from all neighborhood types.

Social Care Education and Training Among US Pediatric Emergency Medicine Fellowship Programs

OBJECTIVE

The aim of the study is to assess the association of social determinants of health (SDOH) education and social needs training on pediatric emergency medicine (PEM) physician perception and practices of social care.

METHODS

Data were derived from the 2021 National Social Care Practices Survey of PEM program directors (PDs) and fellows. Ordinal and binary logistic regression modeling were completed for educational/training factors and social care perspective and practice outcomes.

RESULTS

A national sample of 44 PDs (49% response rate) and 109 fellows (28%) participated. A minority of fellows received SDOH education and social needs training during fellowship. Fellows and PDs with SDOH education had a 3.1 odds (95% confidence interval CI, 1.4-6.9) of screening for social needs, with 4.4 odds among fellows (95% CI, 1.2-20.7). Those with social needs training were more comfortable assessing social risk, with 2.4 odds overall (95% CI, 1.2-4.7) and 3.1 odds among fellows (95% CI, 1.4-6.7). They also had 2.4 odds overall (95% CI, 1.1-4.9) of screening for social needs, with a 2.9 odds among fellows (95% CI, 1.3-6.8).

CONCLUSIONS

Social care education and training appear to be associated with comfort assessing social risk and social needs screening tendency among both PEM PDs and fellows. Key areas for educational interventions are identified among PEM fellows, who are uniquely positioned as clinical leaders and patient advocates.

Altered Symptom Perception in Children With Asthma Is Associated With Poor Childhood Opportunity and Adverse Outcomes

BACKGROUND

Effective asthma self-management requires that children recognize their asthma symptoms when they occur. However, some children have altered symptom perception, which impairs their ability to respond to their asthma symptoms in a timely manner.

OBJECTIVE

To characterize the prevalence and features of altered symptom perception in children aged 5 to 18 years. We hypothesized that children with altered symptom perception would have more features of uncontrolled asthma, more health inequity, and poorer longitudinal asthma outcomes over 12 months.

METHODS

Children (N = 371) completed an outpatient research visit for clinical characterization. Altered symptom perception was defined by discordance between child responses on the 6-item Asthma Control Questionnaire and medical provider-elicited symptoms. Electronic medical records were reviewed for 12 months for the occurrence of an asthma exacerbation treated with systemic corticosteroids and an asthma exacerbation prompting an emergency department visit.

RESULTS

Approximately 15% of children had altered symptom perception and their asthma features were similar to those of children with uncontrolled asthma. Children with altered symptom perception were uniquely distinguished by non-White race and more severe prior exacerbations. These children also resided in ZIP codes with the poorest childhood opportunity (ie, poorest education, health and environmental features, and socioeconomic features). Outcomes of children with altered symptom perception were equally disparate with approximately 2-fold higher odds of a future exacerbation and approximately 3-fold higher odds of an emergency department visit for asthma.

CONCLUSIONS

Altered symptom perception is present in a small but significant number of children with asthma and is related to poorer childhood opportunity and other health inequities that require additional intervention.

Child Opportunity Index and Pediatric Intensive Care Outcomes: A Multicenter Retrospective Study in the United States

OBJECTIVES

To evaluate for associations between a child's neighborhood, as categorized by Child Opportunity Index (COI 2.0), and 1) PICU mortality, 2) severity of illness at PICU admission, and 3) PICU length of stay (LOS).

DESIGN

Retrospective cohort study.

SETTING

Fifteen PICUs in the United States.

PATIENTS

Children younger than 18 years admitted from 2019 to 2020, excluding those after cardiac procedures. Nationally-normed COI category (very low, low, moderate, high, very high) was determined for each admission by census tract, and clinical features were obtained from the Virtual Pediatric Systems LLC (Los Angeles, CA) data from each site.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Among 33,901 index PICU admissions during the time period, median patient age was 4.9 years and PICU mortality was 2.1%. There was a higher percentage of admissions from the very low COI category (27.3%) than other COI categories (17.2-19.5%, p < 0.0001). Patient admissions from the high and very high COI categories had a lower median Pediatric Index of Mortality 3 risk of mortality (0.70) than those from the very low, low, and moderate COI groups (0.71) ( p < 0.001). PICU mortality was lowest in the very high (1.7%) and high (1.9%) COI groups and highest in the moderate group (2.5%), followed by very low (2.3%) and low (2.2%) ( p = 0.001 across categories). Median PICU LOS was between 1.37 and 1.50 days in all COI categories. Multivariable regression revealed adjusted odds of PICU mortality of 1.30 (95% CI, 0.94-1.79; p = 0.11) for children from a very low versus very high COI neighborhood, with an odds ratio [OR] of 0.996 (95% CI, 0.993-1.00; p = 0.05) for mortality for COI as an ordinal value from 0 to 100. Children without insurance coverage had an OR for mortality of 3.58 (95% CI, 2.46-5.20; p < 0.0001) as compared with those with commercial insurance.

CONCLUSIONS

Children admitted to a cohort of U.S. PICUs were often from very low COI neighborhoods. Children from very high COI neighborhoods had the lowest risk of mortality and observed mortality; however, odds of mortality were not statistically different by COI category in a multivariable model. Children without insurance coverage had significantly higher odds of PICU mortality regardless of neighborhood.

The Child Opportunity Index 2.0 and exacerbation-prone asthma in a cohort of urban children

RATIONALE

Social determinants of health underlie disparities in asthma. However, the effects of individual determinants likely interact, so a summary metric may better capture their impact. The Child Opportunity Index 2.0 (COI) is one such tool, yet its association with exacerbation-prone (EP) asthma is unknown.

OBJECTIVE

To investigate the association between the COI and EP asthma and clinical measures of asthma severity in children.

METHODS

We analyzed data from two prospective observational pediatric asthma cohorts (n = 193). Children were classified as EP (≥1 exacerbation in the past 12 months) or exacerbation-null (no exacerbations in the past 5 years). Spirometry, exhaled nitric oxide, IgE, and Composite Asthma Severity Index (CASI) were obtained. The association between COI and EP status was assessed with logistic regression. We fit linear and logistic regression models to test the association between COI and each clinical measure.

RESULTS

A 20-point COI decrease conferred 40% higher odds of EP asthma (OR 1.4; 95%CI 1.1-1.76). The effect was similar when adjusted for age and sex (OR 1.38, 95%CI 1.1-1.75) but was attenuated with additional adjustment for race and ethnicity (OR 1.19, 95%CI 0.92-1.54). A similar effect was seen for the Social/Economic and Education COI domains but not the Health/Environment Domain. A 20-point COI decrease was associated with an increase in CASI of 0.34. COI was not associated with other clinical measures.

CONCLUSIONS

Lower COI was associated with greater odds of EP asthma. This highlights the potential use of the COI to understand neighborhood-level risk and identify community targets to reduce asthma disparities.

Discharge Time of Day and 30-day Hospital Reutilization at an Academic Children's Hospital

BACKGROUND

Pediatric hospital discharge is a complex process. Although morning discharges are operationally preferred, little is known about the association between discharge time of day and discharge outcomes. We assessed whether children discharged from the hospital in the evening have a higher 30-day hospital reutilization rate than those discharged in the morning or afternoon.

METHODS

We conducted a retrospective cohort study on discharges from a children's hospital between July 2016 and December 2019. The cohort was divided into morning, afternoon, and evening discharges. Multivariable modified least-squares regression was used to compare 30-day all-cause hospital reutilization rates between morning, afternoon, and evening discharges while adjusting for demographic and clinical characteristics.

RESULTS

Among 24 994 hospital discharges, 6103 (24.4%) were in the morning, 13 786 (55.2%) were in the afternoon, and 5105 (20.4%) were in the evening. The unadjusted 30-day hospital reutilization rates were 14.1% in children discharged in the morning, 18.2% in children discharged in the afternoon, and 19.3% in children discharged in the evening. The adjusted 30-day hospital reutilization rate was lowest in the morning (6.1%, 95% confidence interval [CI] 4.1%-8.2%), followed by afternoon (9.0%, 95% CI 7.0%-11.0%) and evening discharges (10.1%, 95% CI 8.0%-12.3%). Morning discharge had a significantly lower adjusted 30-day all-cause hospital reutilization rate compared with evening discharge (P < .001), whereas afternoon and evening discharges were not significantly different (P = .06).

CONCLUSIONS

The adjusted 30-day all-cause hospital reutilization rate was higher for evening discharges compared with morning discharges, whereas the rate was not significantly different between afternoon and evening discharges.

Prognostic utility of a novel risk prediction model of 1-year mortality in patients surviving to discharge after surgery for congenital or acquired heart disease

OBJECTIVE

We sought to develop a novel risk prediction model of 1-year mortality after congenital heart surgery that accounts for clinical, anatomic, echocardiographic, and socioeconomic factors.

METHODS

This was a single-center, retrospective review of consecutive index operations for congenital or acquired heart disease, from January 2011 to January 2021, among patients with known survival status at 1 year after discharge from the index hospitalization. The primary outcome was postdischarge mortality at 1 year. Variables of interest included age, prematurity, noncardiac anomalies or syndromes, the Childhood Opportunity Index, primary procedure, major adverse postoperative complications, and the Residual Lesion Score. Logistic regression was used to develop a weighted risk score for the primary outcome. Internal validation using a bootstrap-resampling approach was performed.

RESULTS

Of 10,412 consecutive operations for congenital or acquired heart disease, 8808 (84.6%) cases met entry criteria, including survival to discharge. There were 190 (2.2%) deaths at 1 year postdischarge. A weighted risk score was formulated on the basis of the variables in the final risk prediction model, which included all aforementioned risk factors of interest. This model had a C-statistic of 0.82 (95% confidence interval, 0.80-0.85). The median risk score was 6 (interquartile range, 4-8) points. Patients were categorized as low (score 0-5), medium (score 6-10), high (score 11-15), or very high (score 16-20) risk. The expected probability of mortality was 0.4% ± 0.2%, 2.0% ± 1.1%, 10.1% ± 5.0%, and 36.6% ± 9.6% for low-risk, medium-risk, high-risk, and very high-risk patients, respectively.

CONCLUSIONS

A risk prediction model of 1-year mortality may guide prognostication and follow-up of patients after discharge after surgery for congenital or acquired heart disease.

Impact of Social Determinants of Health on Adolescent Idiopathic Scoliosis Curve Severity

INTRODUCTION

Social determinants of health have been shown to influence the health and outcomes of pediatric patients. Adolescent idiopathic scoliosis (AIS) may be particularly sensitive to such factors as early diagnosis and treatment can obviate the need for surgical intervention. The purpose of this study was to analyze the effect that social determinants of health have on the severity of AIS at presentation and at the time of surgery.

METHODS

A retrospective review was conducted for consecutive patients who underwent posterior spinal fusion for AIS from 2020 to 2022. Demographic data was collected, while insurance status (private vs. public) and childhood opportunity index (COI) categories (LOW vs. HIGH) were used as a proxy for socioeconomic status. Curve magnitude at the initial presentation and at the latest preoperative visit were recorded with a threshold of 25 to 40 degrees considered within the bracing range. Univariate and multivariate analysis was done to compare differences between subgroups as appropriate.

RESULTS

A total of 180 patients with mean initial and preoperative major curve angles of 48 and 60 degrees were included. Statistically significant differences in race and insurance types were appreciated, with the LOW COI group having a higher proportion of underrepresented minority and publicly insured patients than the HIGH COI group ( P <0.001). Patients within the LOW COI group presented with an initial curve that was, on average, 6 degrees more severe than those within the HIGH group ( P =0.009) and a preoperative curve that was 4 degrees larger than those within the HIGH group ( P =0.015). Similarly, only 13% of patients within the LOW COI group presented with curves within the bracing threshold, compared with 31% in the HIGH COI group ( P =0.009).

CONCLUSION

Socioeconomic status plays a significant role in the severity of AIS. Specifically, patients with lower COI tend to present with curve magnitudes beyond what is responsive to nonsurgical treatment, leading to larger curves at the time of surgery. Future work should focus on addressing social inequalities to optimize the treatment and outcomes of AIS patients.

Association of neighborhood opportunity and pediatric hospitalization rates in the United States

We examined associations between a validated, multidimensional measure of social determinants of health and population-based hospitalization rates among children <18 years across 18 states from the 2017 Healthcare Cost and Utilization Project State Inpatient Databases and the US Census. The exposure was ZIP code-level Child Opportunity Index (COI), a composite measure of neighborhood resources and conditions that matter for children's health. The cohort included 614,823 hospitalizations among a population of 29,244,065 children (21.02 hospitalizations per 1000). Adjusted hospitalization rates decreased significantly and in a stepwise fashion as COI increased (p < .001 for each), from 26.56 per 1000 (95% confidence interval [CI] 26.41-26.71) in very low COI areas to 14.76 per 1000 (95% CI 14.66-14.87) in very high COI areas (incidence rate ratio 1.8; 95% CI 1.78-1.81). Decreasing neighborhood opportunity was associated with increasing hospitalization rates among children in 18 US states. These data underscore the importance of social context and community-engaged solutions for health systems aiming to eliminate care inequities.

Lead and delinquency rates; A spatio-temporal perspective

Juvenile delinquency has significant social costs for perpetrators, victims, and communities. To understand the distribution of delinquency offenses this study considers the spatial clustering of juvenile delinquency with lead, race, and neighborhood deprivation using a longitudinal ecological design (N = 4390) and a hierarchical model implemented in a Bayesian methodology that allows space-time interaction. The results show lead exposure is positively related to delinquency offense rates, and over time delinquency rates have become more concentrated in areas with higher levels of lead exposure and shares of Black or African American residents. The study emphasizes the isolation of neighborhoods with social problems and the importance of monitoring patterns of lead and crime at local levels as communities implement lead exposure mitigation programs.

Association of the Child Opportunity Index and Inpatient Illness Severity in the United States, 2018-2019

OBJECTIVE

Children residing in impoverished neighborhoods have reduced access to health care resources. Our objective was to identify potential associations between Child Opportunity Index (COI), a composite score of neighborhood characteristics, and inpatient severity of illness and clinical trajectory among United States (US) children.

METHODS

This retrospective cohort study assessed data using the Pediatric Health Information System Registry from 2018 to 2019. Primary exposure variable was COI level (range: very low [CO1 1], low [COI 2], moderate [COI 3], high [COI 4], and very high [COI 5]). Markers of inpatient clinical severity included index mortality, Pediatric Intensive Care Unit (PICU) admission, invasive mechanical ventilation (IMV), and hospital length of stay (LOS). Subgroup analysis of COI and clinical outcome variation by United States Census Geographic Regions was conducted. Adjusted regression analysis was utilized to understand associations between COI and inpatient clinical severity outcomes.

RESULTS

Of the 132,130 encounters, 44% resided in very low or low COI neighborhoods. In adjusted models, very low COI was associated with increased mortality (aOR: 1.35, 95% CI: 1.05-1.74, P = .018), PICU admission (aOR: 1.06, 95% CI: 1.02-1.11, P = 0.014), IMV (aOR: 1.12, 95% CI: 1.04-1.21, P = .002), and higher hospital LOS (P = .045). Regional variation by COI depicted the East North Central region having the highest rate of mortality (20.5%), P < .001, and PICU admissions (23%), P = .014.

CONCLUSIONS

Our multicenter, retrospective study highlights the interaction between neighborhood-level deprivation and worsened health disparities, indicating a need for prospective study.

Social Drivers of Health and Pediatric Extracorporeal Membrane Oxygenation Outcomes

BACKGROUND

Relationships between social drivers of health (SDoH) and pediatric health outcomes are highly complex with substantial inconsistencies in studies examining SDoH and extracorporeal membrane oxygenation (ECMO) outcomes. To add to this literature with emerging novel SDoH measures, and to address calls for institutional accountability, we examined associations between SDoH and pediatric ECMO outcomes.

METHODS

This single-center retrospective cohort study included children (<18 years) supported on ECMO (2012-2021). SDoH included Child Opportunity Index (COI), race, ethnicity, payer, interpreter requirement, urbanicity, and travel-time to hospital. COI is a multidimensional estimation of SDoH incorporating traditional (eg, income) and novel (eg, healthy food access) neighborhood attributes ([range 0-100] higher indicates healthier child development). Outcomes included in-hospital mortality, ECMO run duration, and length of stay (LOS).

RESULTS

540 children on ECMO (96%) had a calculable COI. In-hospital mortality was 44% with median run duration of 125 hours and ICU LOS 29 days. Overall, 334 (62%) had cardiac disease, 92 (17%) neonatal respiratory failure, 93 (17%) pediatric respiratory failure, and 21 (4%) sepsis. Median COI was 64 (interquartile range 32-81), 323 (60%) had public insurance, 174 (34%) were from underrepresented racial groups, 57 (11%) required interpreters, 270 (54%) had urban residence, and median travel-time was 89 minutes. SDoH including COI were not statistically associated with outcomes in univariate or multivariate analysis.

CONCLUSIONS

We observed no significant difference in pediatric ECMO outcomes according to SDoH. Further research is warranted to better understand drivers of inequitable health outcomes in children, and potential protective mechanisms.

Cumulative Health Vulnerabilities Among Adolescents by Age and Neighborhood Opportunity

BACKGROUND AND OBJECTIVES

Early detection of health vulnerabilities in adolescents is integral to promoting healthy behaviors into adulthood. Our objective was to quantify the prevalence of health vulnerabilities among adolescents and examine differences by age and neighborhood opportunity.

METHODS

In a cross-sectional analysis of electronic health record data for adolescents aged 13 to 18 years with preventive visits in a large pediatric primary care network between September 2021 and September 2022, we examined 5 health vulnerabilities: Tobacco use, substance use, firearm access, condomless intercourse, and depressive symptoms. Health vulnerabilities were assessed via self-reported adolescent health questionnaire and the validated Patient Health Questionnaire-Modified. Prevalence of health vulnerabilities were calculated alone and in combination, and compared by age and by quintile of neighborhood Child Opportunity Index (COI) score. Multivariable logistic regression estimated associations of neighborhood COI with reporting ≥2 health vulnerabilities.

RESULTS

Among 40 197 adolescents (57.7% aged 13-15 years, 66.3% living in "high"/"very high" COI neighborhoods), 29.7% reported at least 1 health vulnerability and 7.9% reported ≥2 vulnerabilities. Cumulative health vulnerabilities were more prevalent among older adolescents and adolescents from lower opportunity neighborhoods. In adjusted models, lower COI was associated with 65% higher odds of having ≥2 vulnerabilities (odds ratio 1.65, 95% confidence interval 1.43-1.91) compared with adolescents from the highest COI quintile.

CONCLUSIONS

Understanding the relationship between health vulnerabilities and neighborhood opportunities among adolescents may allow pediatric primary care providers and health systems to offer more tailored community support services and transdiagnostic specialized care navigation to address the health needs of teens with multiple vulnerabilities.

Variation over Time in Child and Neighborhood Characteristics Associated with COVID-19

Introduction

To examine the associations between child and neighborhood characteristics and incidence of COVID-19 infection during the first 19 months of the pandemic.

Study Design

We utilized individual electronic health record data and corresponding census tract characteristics for pediatric SARS-CoV-2 cases (age <18 years) from March 23, 2020 to September 30, 2021 with molecular tests resulted at a children's health system in Colorado. We compared associations between individual SARS-CoV-2 cases and census tract SARS-CoV-2 positivity rates over three time periods (TP1: March-September 2020; TP2: October 2020-March 2021; TP3: April-September 2021) using multinomial logistic regression for individual associations and negative binomial regression for census tract associations.

Results

We included 7498 pediatric SARS-CoV-2 cases and data from 711 corresponding census tracts. Spanish preferred health care language was associated with SARS-CoV-2 positivity for TP1 (odds ratio [OR] 4.9, 95% confidence interval [CI] 3.7-6.5) and TP2 (OR 2.01, 95% CI 1.6-2.6) compared with TP3. Other non-English preferred health care language was associated with SARS-CoV-2 positivity in TP1 (OR 2.4, 95% CI 1.4-4.2). Increasing percentage internationally born in a census tract was associated with SARS-CoV-2 positivity for TP1 (multivariable incident rate ratio [IRR]=1.040, p<0.0001), TP2 (multivariable IRR=1.028, p<0.0001), and in all TP combined (multivariable IRR=1.024, p<0.0001).

Discussion

Our study is notable for the identification of COVID-19 disparities among children in immigrant families and communities, particularly early in the pandemic. Addressing disparities for immigrant communities requires targeted investments in public health infrastructure.

Disparities in Receipt of Guideline-adherent Blood Pressure Screening: An Observational Examination of Electronic Health Record Data from a Massachusetts Healthcare System

OBJECTIVE

To describe the prevalence of blood pressure (BP) screening according to the 2017 American Academy of Pediatrics (AAP) guidelines and differences according to social vulnerability indicators.

STUDY DESIGN

We extracted electronic health record data from January 1, 2018, through December 31, 2018, from the largest healthcare system in Central Massachusetts. Outpatient visits for children aged 3-17 years without a prior hypertension diagnosis were included. Adherence was defined by the American Academy of Pediatrics guideline (≥1 BP screening for children with a body mass index [BMI] of <95th percentile) and at every encounter for children with a BMI of ≥95th percentile). Independent variables included social vulnerability indicators at the patient level (insurance type, language, Child Opportunity Index, race/ethnicity) and clinic level (location, Medicaid population). Covariates included child's age, sex, and BMI status, and clinic specialty, patient panel size, and number of healthcare providers. We used direct estimation to calculate prevalence estimates and multivariable mixed effects logistic regression to determine the odds of receiving guideline-adherent BP screening.

RESULTS

Our sample comprised 19 695 children (median age, 11 years; 48% female) from 7 pediatric and 20 family medicine clinics. The prevalence of guideline-adherent BP screening was 89%. In our adjusted model, children with a BMI of ≥95th percentile, with public insurance, and who were patients at clinics with larger Medicaid populations and larger patient panels had a lower odds of receiving guideline-adherent BP screening.

CONCLUSIONS

Despite overall high adherence to BP screening guidelines, patient- and clinic-level disparities were identified.

Neighborhood deprivation and childhood opportunity indices are associated with violent injury among children in Los Angeles County

BACKGROUND

Previous research has demonstrated mixed relationships between individual neighborhood socioeconomic factors and incidences of violence, such as poverty level, population density, and income inequality. We used the Childhood Opportunity Index and Area Disadvantage Index to evaluate the relationship between neighborhood characteristics and the number of incidents of violence among children across the zip codes of Los Angeles (LA) County.

METHODS

We performed a retrospective cross-sectional study of children younger than 18 years from 2017 to 2019 who were entered in the LA County Trauma and Emergency Medicine Information System registry with violent mechanisms of injury, including gunshot, stabbing, or assault. Mechanisms classified as self-inflicted injuries were excluded from the study. The number of incidences of violent mechanism per 100,000 persons younger than 18 years for each zip code was calculated using population data from the US Census American Community Survey 5-Year estimates from 2019. The incidences of violence per capita younger than 18 years for each zip code was compared with the zip code Area Deprivation Index and Childhood Opportunity Index using logistic regression models.

RESULTS

There were 6,791 trauma activations in LA County over the study period, 12.8% (n = 866) of which were due to violence. The mean prevalence of pediatric violent mechanism of injury per zip code was 4 cases per 100,000 persons younger than 18 years. Most injuries were the result of firearms (n = 345 [60.4%]) and occurred among Hispanic/Latino children (n = 362 [57.1%]). There were significantly greater rates of violent injury among children from highest disadvantage (odds ratio, 8.84) and lowest opportunity (odds ratio, 42.48) zip codes.

CONCLUSION

Children living in high disadvantage or low opportunity zip codes had greater rates of violent injury. Further study of neighborhood factors is needed to develop targeted effective interventions to reduce violent injuries among children living in low opportunity areas.

Neighborhood Childhood Opportunity, Race/Ethnicity, and Surgical Outcomes in Children With Congenital Heart Disease

BACKGROUND

Racial and ethnic disparities in outcomes for children with congenital heart disease (CHD) coexist with disparities in educational, environmental, and economic opportunity.

OBJECTIVES

We sought to determine the associations between childhood opportunity, race/ethnicity, and pediatric CHD surgery outcomes.

METHODS

Pediatric Health Information System encounters aged <18 years from 2016 to 2022 with International Classification of Diseases-10th edition codes for CHD and cardiac surgery were linked to ZIP code-level Childhood Opportunity Index (COI), a score of neighborhood educational, environmental, and socioeconomic conditions. The associations of race/ethnicity and COI with in-hospital surgical death were modeled with generalized estimating equations and formal mediation analysis. Neonatal survival after discharge was modeled by Cox proportional hazards.

RESULTS

Of 54,666 encounters at 47 centers, non-Hispanic Black (Black) (OR: 1.20; P = 0.01), Asian (OR: 1.75; P < 0.001), and Other (OR: 1.50; P < 0.001) groups had increased adjusted mortality vs non-Hispanic Whites. The lowest COI quintile had increased in-hospital mortality in unadjusted and partially adjusted models (OR: 1.29; P = 0.004), but not fully adjusted models (OR: 1.14; P = 0.13). COI partially mediated the effect of race/ethnicity on in-hospital mortality between 2.6% (P = 0.64) and 16.8% (P = 0.029), depending on model specification. In neonatal multivariable survival analysis (n = 13,987; median follow-up: 0.70 years), the lowest COI quintile had poorer survival (HR: 1.21; P = 0.04).

CONCLUSIONS

Children in the lowest COI quintile are at risk for poor outcomes after CHD surgery. Disproportionally increased mortality in Black, Asian, and Other populations may be partially mediated by COI. Targeted investment in low COI neighborhoods may improve outcomes after hospital discharge. Identification of unmeasured factors to explain persistent risk attributed to race/ethnicity is an important area of future exploration.

Measures of Neighborhood Opportunity and Adherence to Recommended Pediatric Primary Care

Importance

Neighborhood conditions are known to broadly impact child health. Research to date has not examined the association of the Childhood Opportunity Index (COI), a multidimensional indicator of neighborhood environment conditions, specifically with pediatric primary care outcomes.

Objective

To determine the association of neighborhood opportunity measured by the COI with health metrics commonly captured clinically in pediatric primary care, reflecting both access to preventive care and child well-being.

Design, Setting, and Participants

This cross-sectional observational study used electronic health record data from a large pediatric primary care network in the northeastern US. Participants included patients aged 0 to 19 years who were active in the primary care network between November 2020 and November 2022. Data were analyzed in December 2022.

Exposure

Census tract-level COI overall score (in quintiles).

Main Outcomes and Measures

Outcomes included up-to-date preventive care and immunization status and presence of obesity, adolescent depression and suicidality, and maternal depression and suicidality. Multivariable mixed-effects logistic regressions estimated associations of these outcomes with COI quintiles, adjusted for age, sex, race and ethnicity, and insurance type.

Results

Among 338 277 patients (mean [SD] age, 9.8 [5.9] years; 165 223 female [48.8%]; 158 054 [46.7%] non-Hispanic White, 209 482 [61.9%] commercially insured), 81 739 (24.2%) and 130 361 (38.5%) lived in neighborhoods of very low and very high COI, respectively. Living in very high COI neighborhoods (vs very low COI) was associated with higher odds of being up-to-date on preventive visits (odds ratio [OR], 1.40; 95% CI, 1.32-1.48) and immunizations (OR, 1.77; 95% CI, 1.58-2.00), and with lower odds of obesity (OR, 0.55; 95% CI, 0.52-0.58), adolescent depression (OR, 0.78; 95% CI, 0.72-0.84) and suicidality (OR, 0.79; 95% CI, 0.73-0.85), and maternal depression (OR, 0.78; 95% CI, 0.72-0.86) and suicidality (OR, 0.71; 95% CI, 0.61-0.83).

Conclusions and Relevance

This cross-sectional study of electronic health record data found that neighborhood opportunity was associated with multiple pediatric primary care outcomes. Understanding these associations can help health systems identify neighborhoods that need additional support and advocate for and develop partnerships with community groups to promote child well-being. The findings underscore the importance of improving access to preventive care in low COI communities.

Racial and Ethnic Differences in Insurer Classification of Nonemergent Pediatric Emergency Department Visits

Importance

Government and commercial health insurers have recently enacted policies to discourage nonemergent emergency department (ED) visits by reducing or denying claims for such visits using retrospective claims algorithms. Low-income Black and Hispanic pediatric patients often experience worse access to primary care services necessary for preventing some ED visits, raising concerns about the uneven impact of these policies.

Objective

To estimate potential racial and ethnic disparities in outcomes of Medicaid policies for reducing ED professional reimbursement based on a retrospective diagnosis-based claims algorithm.

Design, Setting, and Participants

This simulation study used a retrospective cohort of pediatric ED visits (aged 0-18 years) for Medicaid-insured children and adolescents appearing in the Market Scan Medicaid database between January 1, 2016, and December 31, 2019. Visits missing date of birth, race and ethnicity, professional claims data, and Current Procedural Terminology codes of billing level of complexity were excluded, as were visits that result in admission. Data were analyzed from October 2021 to June 2022.

Main Outcomes and Measures

Proportion of ED visits algorithmically classified as nonemergent and simulated per-visit professional reimbursement after applying a current reimbursement reduction policy for potentially nonemergent ED visits. Rates were calculated overall and compared by race and ethnicity.

Results

The sample included 8 471 386 unique ED visits (43.0% by patients aged 4-12 years; 39.6% Black, 7.7% Hispanic, and 48.7% White), of which 47.7% were algorithmically identified as potentially nonemergent and subject to reimbursement reduction, resulting in a 37% reduction in ED professional reimbursement across the study cohort. More visits by Black (50.3%) and Hispanic (49.0%) children were algorithmically identified as nonemergent when compared with visits by White children (45.3%; P < .001). Modeling the impact of the reimbursement reductions across the cohort resulted in expected per-visit reimbursement that was 6% lower for visits by Black children and 3% lower for visits by Hispanic children relative to visits by White children.

Conclusions and Relevance

In this simulation study of over 8 million unique ED visits, algorithmic approaches for classifying pediatric ED visits that used diagnosis codes identified proportionately more visits by Black and Hispanic children as nonemergent. Insurers applying financial adjustments based on these algorithmic outputs risk creating uneven reimbursement policies across racial and ethnic groups.

Discordance between Subjective and Objective Assessments of Activity after Pediatric Appendectomy

BACKGROUND

Physical activity recovery after pediatric surgery can be assessed using objective measures such as step counts, but practice currently relies on subjective assessment by proxy. It is unclear how subjective and objective assessments of activity relate. We compared caregiver assessment of return to normal physical activity after pediatric appendectomy to step count recovery measured by a Fitbit.

METHODS

Pediatric patients who underwent appendectomy were recruited between 2020 and 2022 to be monitored for 21 d with a Fitbit. Patients were grouped by the postoperative day (POD) (7, 14, or 21) their caregiver first reported their activity was "back to normal." Objective return to normal step count was estimated for each group by modeling the inflection point from increasing steps to a plateau. These measures were determined discordant if the subjective report remained outside the modeled 95% confidence interval (CI) for the day the group plateaued.

RESULTS

Thirty-nine simple appendicitis and 40 complicated appendicitis patients were recruited. Among simple appendicitis patients, daily steps plateaued on POD 10.8 (95% CI 7.4-14.3), POD 14.0 (95% CI 11.0-17.1), and POD 11.1 (95% CI 6.9-15.3) for the day 7, day 14, and day 21 groups, respectively. Complicated appendicitis groups plateaued on POD 12.8 (95% CI 8.7-16.9), POD 15.2 (95% CI 11.1-19.3), and POD 16.7 (95% CI 12.3-21.0), respectively. Significant discordance was observed between subjective and objective assessments for the day 7 and day 14 simple groups and for the day 7 complicated group.

CONCLUSIONS

There was significant discordance between caregiver and accelerometer-assessed activity recovery after pediatric surgery. Development of objective measures of recovery could help standardize assessment of children's recovery after surgery.

Children with severe sepsis: relationship between community level income and morbidity and mortality

BACKGROUND

Health disparities surrounding pediatric severe sepsis outcomes remains unclear. We aimed to measure the relationship between indicators of socioeconomic status and mortality, hospital length of stay (LOS), and readmission rates among children hospitalized with severe sepsis.

METHODS

Children 0-18 years old, hospitalized with severe sepsis in the Nationwide Readmissions Database (2016-2018) were included. The primary exposure was median household income by ZIP Code of residence, divided into quartiles.

RESULTS

We identified 15,214 index pediatric severe sepsis hospitalizations. There was no difference in hospital mortality rate or readmission rate across income quartiles. Among survivors, patients in Q1 (lowest income) had a 2 day longer LOS compared to those in Q4 (Median 10 days [IQR 4-21] vs 8 days [IQR 4-18]; p < 0.0001). However, there was no difference after adjusting for multiple covariates.

CONCLUSIONS

Children living in Q1 had a 2 day longer LOS versus their peers in Q4. This was not significant on multivariable analysis, suggesting income quartile is not driving this difference. As pediatric severe sepsis remains an important source of morbidity and mortality in critically ill children, more sensitive metrics of socioeconomic status may better elucidate any disparities.

IMPACT

Children with severe sepsis living in the lowest income ZIP Codes may have longer hospital stays compared to peers in higher income communities. More precise metrics of socioeconomic status are needed to better understand health disparities in pediatric severe sepsis.

Distribution of Emergency Department Encounters and Subsequent Hospital Admissions for Children by Child Opportunity Index

OBJECTIVE

To evaluate differences in emergency department (ED) utilization and subsequent admission among children by Child Opportunity Index (COI).

METHODS

We performed a cross-sectional study of pediatric (<18 years) encounters to 194 EDs in Illinois from 2016 to 2020. Each encounter was assigned to quntiles of COI 2.0 by postal code. We described the difference in the percent of encounters between lower (Very Low and Low) and higher (Very High and High) COI overall and among diagnoses with overrepresentation from lower COI groups. We evaluated the association of diagnosis with COI in ordinal models adjusted for demographics.

RESULTS

There were 4,653,026 eligible ED encounters classified by COI as Very Low (28.6%), Low (24.8%), Moderate (20.3%), High (15.6%), and Very High (10.8%) (difference between low and high COI encounters 27.0%). Diagnoses with the greatest difference between low and high COI were eye infection, upper respiratory tract infections, and cough. The COI distribution for children admitted from the ED (n = 140,298) was 29.1% Very Low, 19.3% Low, 18.2% Moderate, 17.7% High, and 15.7% Very High (percent difference 15.1%). Diagnoses with the greatest differences between low and high COI among admitted patients were sickle cell crisis, asthma, and influenza. All ED diagnoses and 7/12 admission diagnoses were associated with lower COI in multivariable ordinal models.

CONCLUSIONS

Children from lower COI areas are overrepresented in ED and inpatient encounters overall and within certain diagnosis groups. Further research is required to examine how health outcomes may be influenced by the structural and contextual characteristics of a child's neighborhood.

Contemporary Socioeconomic and Childhood Opportunity Disparities in Congenital Heart Surgery

BACKGROUND

While singular measures of socioeconomic status have been associated with outcomes after surgery for congenital heart disease, the multifaceted pathways through which a child's environment impacts similar outcomes remain incompletely characterized. We sought to evaluate the association between childhood opportunity level and adverse outcomes after congenital heart surgery.

METHODS

Data from patients undergoing congenital cardiac surgery from January 2011 to January 2020 at a quaternary referral center were retrospectively reviewed. Outcomes of interest included predischarge (early) mortality or transplant, postoperative hospital length-of-stay, inpatient cost of hospitalization, postdischarge (late) mortality or transplant, and late unplanned reintervention. The primary predictor was a US census tract-based, nationally-normed composite metric of contemporary child neighborhood opportunity comprising 29 indicators across 3 domains (education, health and environment, and socioeconomic), categorized as very low, low, moderate, high, and very high. Associations between childhood opportunity level and outcomes were evaluated using logistic regression (early mortality), generalized linear (length-of-stay and cost), Cox proportional hazards (late mortality), or competing risk (late reintervention) models, adjusting for baseline patient-related factors, case complexity, and residual lesion severity.

RESULTS

Of 6133 patients meeting entry criteria, the median age was 2.0 years (interquartile range, 3.6 months-8.3 years). There were 124 (2.0%) early deaths or transplants, the median postoperative length-of-stay was 7 days (interquartile range, 5-13 days), and the median inpatient cost was $76 000 (interquartile range, $50 000-130 000). No significant association between childhood opportunity level and early mortality or transplant was observed (P=0.21). On multivariable analysis, children with very low and low opportunity had significantly longer length-of-stay and incurred higher costs compared with those with very high opportunity (all P<0.05). Of 6009 transplant-free survivors of hospital discharge, there were 175 (2.9%) late deaths or transplants, and 1008 (16.8%) reinterventions at up to 10.5 years of follow-up. Patients with very low opportunity had a significantly greater adjusted risk of late death or transplant (hazard ratio, 1.7 [95% CI, 1.1-2.6]; P=0.030) and reintervention (subdistribution hazard ratio, 1.9 [95% CI, 1.5-2.3]; P<0.001), versus those with very high opportunity.

CONCLUSIONS

Childhood opportunity level is independently associated with adverse outcomes after congenital heart surgery. Children from resource-limited settings thus constitute an especially high-risk cohort that warrants closer surveillance and tailored interventions.
