RESUMEN
BACKGROUND: A decrease in the incidence of Kawasaki disease during the COVID-19 pandemic has been reported globally. Yet, previous US studies utilized patient populations of limited size and geographic scope, leaving a knowledge gap regarding the national trend. Employing a large sample size will increase the generalizability of the results and allow for more detailed analyses. METHODS: The observational study using the 2016-2020 National (Nationwide) Inpatient Sample examined changes in the Kawasaki disease hospitalization rate in pediatric patients during the COVID-19 pandemic. Sensitivity analyses examined hospitalizations between October and December each year, as the code for multisystem inflammatory syndrome in children was implemented in October 2020. RESULTS: In total, 24,505 hospitalizations with Kawasaki disease diagnoses were examined. Hospitalization rates were 65.1 and 53.8 per 1,000,000 pediatric population during the prepandemic and pandemic periods, respectively. Sensitivity analyses showed an overall decrease of 36.1%, with larger decreases for patients 1-4 years old (49.6%), males (40.0%), Asians or Pacific Islanders (57.9%) and patients in the South (47.5%), compared with their counterparts. Associations of the pandemic period with longer lengths of stay and higher daily costs were detected (adjusted mean ratio 1.11; P < 0.01 for length of stay, and adjusted mean ratio 1.33, P < 0.01 for costs). CONCLUSIONS: A decrease in the incidence of Kawasaki disease during the COVID-19 pandemic was observed nationwide in the United States. Contrary to a report from Japan, we did not observe a relationship between population density and a decrease in Kawasaki disease hospitalization. More detailed analyses in targeted geographical areas may provide further insights.

We evaluated the association between implementation of state-mandated pulse oximetry screening (POS) and rates of emergency hospitalizations among infants with Critical Congenital Heart Disease (CCHD) and assessed differences in that association across race/ethnicity. We hypothesized that emergency hospitalizations among infants with CCHD decreased after implementation of mandated POS and that the reduction was larger among racial and ethnic minorities compared to non-Hispanic Whites. We utilized statewide inpatient databases from Arizona, California, Kentucky, New Jersey, New York, and Washington State (2010-2014). A difference-in-differences model with negative binomial regression was used. We identified patients with CCHD whose hospitalizations between three days and three months of life were coded as "emergency" or "urgent" or occurred through the emergency department. Numbers of emergency hospitalizations aggregated by month and state were used as outcomes. The intervention variable was an implementation of state-mandated POS. Difference in association across race/ethnicity was evaluated with interaction terms between the binary variable indicating the mandatory policy period and each race/ethnicity group. The model was adjusted for state-specific variables, such as percent of female infants and percent of private insurance. We identified 9,147 CCHD emergency hospitalizations. Among non-Hispanic Whites, there was a 22% (Confidence Interval [CI] 6%-36%) decline in CCHD emergency hospitalizations after implementation of mandated POS, on average. This decline was 65% less among non-Hispanic Blacks compared to non-Hispanic Whites. Our study detected an attenuated association with decreased number of emergency hospitalizations among Black compared to White infants. Further research is needed to clarify this disparity.

OBJECTIVE: Our objective was to gauge adherence to nationally endorsed protocols in implementation of pulse oximetry (POx) screening for critical congenital heart disease (CCHD) in infants after mandate by all states and to assess associated characteristics. STUDY DESIGN: Between March and October 2019, an online questionnaire was administered to nurse supervisors who oversee personnel conducting POx screening. The questionnaire used eight questions regarding performance and interpretation of screening protocols to measure policy consistency, which is adherence to nationally endorsed protocols for POx screening developed by professional medical societies. Multilevel linear regression models evaluated associations between policy consistency and characteristics of hospitals and individuals, state of hospital location, early versus late mandate adopters, and state reporting requirements. RESULTS: Responses from 189 nurse supervisors spanning 38 states were analyzed. Only 17% received maximum points indicating full policy consistency, and 24% selected all four options for potential hypoxia that require a repeat screen. Notably, 33% did not recognize ≤90% SpO2 as an immediate failed screen and 31% responded that an infant with SpO2 of 89% in one extremity will be rescreened by nurses in an hour rather than receiving an immediate physician referral. Lower policy consistency was associated with lack of state reporting mandates (beta = -1.23 p = 0.01) and early adoption by states (beta = -1.01, p < 0.01). CONCLUSION: When presented with SpO2 screening values on a questionnaire, a low percentage of nurse supervisors selected responses that demonstrated adherence to nationally endorsed protocols for CCHD screening. Most notably, almost one-third of respondents did not recognize ≤90% SpO2 as a failed screen that requires immediate physician follow-up. In addition, states without reporting mandates and early adopter states were associated with low policy consistency. Implementing state reporting requirements might increase policy consistency, but some inconsistency may be the result of unique protocols in early adopter states that differ from nationally endorsed protocols. KEY POINTS: · Low adherence to nationally endorsed protocols.. · Inconsistent physician follow-up to hypoxia.. · Reporting improved consistency with national policy..
RESUMEN
INTRODUCTION: The purpose of this study was to examine the association between prior emergency department (ED) visit or hospitalization and subsequent suicide attempt among homeless youth aged 10-17 years old. METHODS: With New York statewide databases, a case-control design was conducted. Cases and controls were homeless patients with an ED visit or hospitalization due to suicide attempt (cases) or appendicitis (controls) between April and December. We examined ED and inpatient records for 90 days prior to the visit for suicide attempt or appendicitis. The primary exposure variable was prior healthcare utilization for any reason other than the following four reasons: mental health disorder, substance use, self-harm, and other injuries. Multivariable logistic regression models, with year fixed effect and hospital random effect, were used. RESULTS: A total of 335 cases and 742 controls were identified. Cases had lower odds of prior healthcare utilization for any reason other than the four reasons listed above. (adjusted Odds Ratio [aOR]: 0.53, p-value = 0.03). CONCLUSIONS: The association between prior healthcare utilization and decreased risk of suicide attempt among homeless youth may be due to comprehensive care provided during healthcare utilization. It may also reflect the presence of a social network that provided a protective effect.

OBJECTIVE: To assess differences in rates of postpartum hospitalisations among homeless women compared with non-homeless women. DESIGN: Cross-sectional secondary analysis of readmissions and emergency department (ED) utilisation among postpartum women using hierarchical regression models adjusted for age, race/ethnicity, insurance type during delivery, delivery length of stay, maternal comorbidity index score, other pregnancy complications, neonatal complications, caesarean delivery, year fixed effect and a birth hospital random effect. SETTING: New York statewide inpatient and emergency department databases (2009-2014). PARTICIPANTS: 82 820 and 1 026 965 postpartum homeless and non-homeless women, respectively. MAIN OUTCOME MEASURES: Postpartum readmissions (primary outcome) and postpartum ED visits (secondary outcome) within 6 weeks after discharge date from delivery hospitalisation. RESULTS: Homeless women had lower rates of both postpartum readmissions (risk-adjusted rates: 1.4% vs 1.6%; adjusted OR (aOR) 0.87, 95% CI 0.75 to 1.00, p=0.048) and ED visits than non-homeless women (risk-adjusted rates: 8.1% vs 9.5%; aOR 0.83, 95% CI 0.77 to 0.90, p<0.001). A sensitivity analysis stratifying the non-homeless population by income quartile revealed significantly lower hospitalisation rates of homeless women compared with housed women in the lowest income quartile. These results were surprising due to the trend of postpartum hospitalisation rates increasing as income levels decreased. CONCLUSIONS: Two factors likely led to lower rates of hospital readmissions among homeless women. First, barriers including lack of transportation, payment or childcare could have impeded access to postpartum inpatient and emergency care. Second, given New York State's extensive safety net, discharge planning such as respite and sober living housing may have provided access to outpatient care and quality of life, preventing adverse health events. Additional research using outpatient data and patient perspectives is needed to recognise how the factors affect postpartum health among homeless women. These findings could aid in lowering readmissions of the housed postpartum population.

OBJECTIVE: Substance abuse, particularly among homeless youths, is a significant public health challenge in the United States. Detailed data about health care utilization resulting from this preventable behavior remain sparse. This study aimed to compare health care utilization rates related to substance abuse among homeless and nonhomeless youths. METHODS: A secondary data analysis evaluated records of homeless and nonhomeless patients under age 25 with a primary diagnosis of substance abuse, identified in 2013 and 2014 New York Statewide Inpatient and Emergency Department (ED) Databases. Outcomes included ED visit rate, hospitalization rate, in-hospital mortality, cost, length of stay (LOS), intensive care unit (ICU) utilization, and revisit or readmission rate. Multivariable regression models with a year fixed effect and facility random effect were used to evaluate the association between homelessness and each outcome. RESULTS: A total of 68,867 cases included hospitalization or an ED visit related to substance abuse (68,118 nonhomeless and 749 homeless cases). Rates of ED visits related to substance abuse were 9.38 and 4.96, while rates of hospitalizations related to substance abuse were 10.53 and 1.01 per 1,000 homeless and nonhomeless youths, respectively. Homeless patients were more likely to utilize and revisit the ICU, be hospitalized or readmitted, incur higher costs, and have longer LOS than nonhomeless youths (all p<0.01). CONCLUSIONS: The hospitalization and ED visit rates related to substance abuse were 10 and two times higher among homeless youths compared with nonhomeless youths, respectively. Detailed observation is needed to clarify whether homeless youths receive high-quality care for substance abuse when necessary.

Suicide remains the leading cause of death among homeless youth. We assessed differences in health-care utilization between homeless and nonhomeless youth presenting to the emergency department or hospital after a suicide attempt. New York Statewide Inpatient and Emergency Department Databases (2009-2014) were used to identify homeless and nonhomeless youth aged 10-17 who utilized health-care services following a suicide attempt. To evaluate associations with homelessness, we used logistic regression models for use of violent means, intensive care unit utilization, log-transformed linear regression models for hospitalization cost, and negative binomial regression models for length of stay. All models adjusted for individual characteristics with a hospital random effect and year fixed effect. We identified 18,026 suicide attempts with health-care utilization rates of 347.2 (95% confidence interval (CI): 317.5, 377.0) and 67.3 (95% CI: 66.3, 68.3) per 100,000 person-years for homeless and nonhomeless youth, respectively. Length of stay for homeless youth was statistically longer than that for nonhomeless youth (incidence rate ratio = 1.53, 95% CI: 1.32, 1.77). All homeless youth who visited the emergency department after a suicide attempt were subsequently hospitalized. This could suggest a higher acuity upon presentation among homeless youth compared with nonhomeless youth. Interventions tailored to homeless youth should be developed.

OBJECTIVE: To evaluate the impact of state-mandated policies for pulse oximetry screening on healthcare utilisation, with a focus on use of echocardiograms. DATA SOURCES/STUDY SETTING: Healthcare Cost and Utilisation Project, Statewide Inpatient Databases from 2008 to 2014 from six states. METHODS: We defined pre- and post-mandate cohorts based on dates when pulse oximetry became mandated in each state. Linear segmented regression models for interrupted time series assessed associations between implementation of the screening and changes in rate of newborns with Critical CHD-negative echocardiogram results. We also evaluated the changes in rate of newborns who underwent echocardiogram but were not diagnosed with any health issues that could cause hypoxemia. RESULTS: We identified 5967 critical CHD-negative echocardiograms (2847 and 3120 in the pre- and post-mandate periods, respectively). Our models detected a statistically significant increasing trend in rate of critical CHD-negative echocardiograms in the pre-mandate period (Incidence Rate Ratio: 1.08, p = 0.02), but did not detect any statistical differences in changes between pre- and post-mandate periods (Incidence Rate Ratio: 0.93, p = 0.14). Among non-Whites, an increasing trend of Critical CHD-negative echocardiogram during the pre-mandate period was detected (Incidence Rate Ratio 1.12, p < 0.01) and was attenuated during the post-mandate period (Incidence Rate Ratio 0.89, p = 0.02). Similar results were observed in the sensitivity analyses among both Whites and non-Whites. CONCLUSIONS: Results suggest that mandatory state screening policies are associated with reductions in false-positive screening rates for hypoxemic conditions, with reductions primarily attributed to trends among non-Whites.

OBJECTIVE: This study aims to describe differences in health care utilization between homeless and nonhomeless minors with diabetes. RESEARCH DESIGN AND METHODS: Data from the Healthcare Cost and Utilization Project's Statewide Inpatient Database from New York for years 2009-2014 were examined to identify pediatric patients <18 years old with diabetes. Outcomes of interest included hospitalization rate, in-hospital mortality, admission through the emergency department (ED), diabetic ketoacidosis (DKA), hospitalization cost, and length of stay (LOS). Other variables of interest included age-group, race/ethnicity, insurance type, and year. Multivariate logistic regression models were used for in-hospital mortality, admission through ED, and DKA. Log-transformed linear regression models were used for hospitalization cost, and negative binomial regression models were used for LOS. RESULTS: A total of 643 homeless and 10,559 nonhomeless patients were identified. The hospitalization rate was higher among homeless minors, with 3.64 per 1,000 homeless population compared with 0.38 per 1,000 in the nonhomeless population. A statistically significant higher readmission rate was detected among homeless minors (20.4% among homeless and 14.1% among nonhomeless, P < 0.01). Lower rates of DKA (odds ratio 0.75, P = 0.02), lower hospitalization costs (point estimate 0.88, P < 0.01), and longer LOS (incidence rate ratio 1.20, P < 0.01) were detected among homeless minors compared with nonhomeless minors. CONCLUSIONS: This study found that among minors with diabetes, those who are homeless experience a higher hospitalization rate than the nonhomeless. Housing instability, among other environmental factors, may be targeted for intervention to improve health outcomes.

BACKGROUND AND OBJECTIVES: Asthma is widely prevalent among US children, particularly in homeless children, who often lack proper medication storage or the ability to avoid environmental triggers. In this study, we assess asthma-attributed health care use among homeless youth. We hypothesize that asthma hospitalization rates, symptom severity, and admission through the emergency department (ED) will be higher among homeless youth compared with nonhomeless youth. METHODS: This secondary data analysis identified homeless and nonhomeless pediatric patients (<18 years old) with a primary diagnosis of asthma from New York statewide inpatient databases between 2009 and 2014. Hospitalization rate, readmission rate, admission through the ED, ventilation use, ICU admittance, hospitalization cost, and length of stay were measured. RESULTS: We identified 71 837 asthma hospitalizations, yielding 73.8 and 2.3 hospitalizations per 1000 homeless and nonhomeless children, respectively. Hospitalization rates varied by nonhomeless income quartile, with low-income children experiencing higher rates (5.4) of hospitalization. Readmissions accounted for 16.0% of homeless and 12.5% of nonhomeless hospitalizations. Compared with nonhomeless patients, homeless patients were more likely to be admitted from the ED (odds ratio 1.96; 95% confidence interval: 1.82-2.12; P < .01), and among patients >5 years old, homeless patients were more likely to receive ventilation (odds ratio 1.45; 95% confidence interval: 1.01-2.09; P = .04). No significant differences were observed in ICU admittance, cost, or length of stay. CONCLUSIONS: Homeless youth experience an asthma hospitalization rate 31 times higher than nonhomeless youth, with higher rates of readmission. Homeless youth live under uniquely challenging circumstances. Tailored asthma control strategies and educational intervention could greatly reduce hospitalizations.

This study investigated patient characteristics in paediatric hospitalisations for hypertrophic cardiomyopathy. We used Nationwide Inpatient Sample, which is the largest all-payer inpatient database in the United States, yielding nationally representative estimates, from 2001 to 2014. ICD-9-CM diagnostic codes identified hospitalisations for patients with hypertrophic cardiomyopathy and <18 years. Outcomes included yearly rate of hospitalisation, death, admission via emergency department, and need for surgery. Predictors of interest were age groups (<1, 1-9, and ⩾10 y/o), sex, and race/ethnicity. Logistic regression modelled associations, adjusted by patient- and hospital-level variables. With 2302 weighted hospitalisations, hospitalisation rates were 0.22 per 100,000 children/year, with higher rates for <1 y/o (0.42) and ⩾10 y/o (0.31). Male-to-female ratios were more prominent in the oldest age group; 2.7:1 in ⩾10 y/o versus less than 1.7:1 for <10 y/o. In-hospital mortality was 1.5%, with highest mortality rates among the <1 y/o (6.3%). Children ⩾10 y/o had 5.59 times higher risk of admission from the emergency department than 1-9 y/o age group. Both ⩾10 and <1 y/o age groups had lower risk of surgical intervention compared to the 1-9 y/o group with odds ratio 0.56 and 0.26, respectively. Black children had higher risk of admission from the emergency department than White children with odds ratio 2.78. A relation between age group and sex was observed, with sex-based differences in prevalence and treatment of hypertrophic cardiomyopathy becoming more pronounced with age. Further studies are needed to clarify mechanisms behind age and racial disparity in hospitalisation, especially admission source.

OBJECTIVE: Regionalization directs patients to high-volume hospitals for specialized care. We investigated regionalization trends and outcomes in pediatric cardiac surgery. DATA SOURCES/STUDY SETTING: Statewide inpatient data from eleven states between 2000 and 2012. STUDY DESIGN: Mortality, length of stay (LOS), and cost were assessed using multivariable hierarchical regression with state and year fixed effects. Primary predictor was hospital case-volume, categorized into low-, medium-, and high-volume tertiles. DATA COLLECTION/EXTRACTION METHODS: We used Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1) to select pediatric cardiac surgery discharges. PRINCIPAL FINDINGS: In total, 2841 (8.5 percent), 8348 (25.1 percent), and 22 099 (66.4 percent) patients underwent heart surgeries in low-, medium-, and high-volume hospitals. Mortality decreased over time, but remained higher in low- and medium-volume hospitals. High-volume hospitals had lower odds of mortality and cost than low-volume hospitals (odds ratio [OR] 0.59, P < 0.01, and relative risk [RR] 0.91, P < 0.01, respectively). LOS was longer for high- and medium-volume hospitals, compared to low-volume hospitals (high-volume: RR 1.18, P < 0.01; medium-volume: RR 1.05, P < 0.01). CONCLUSIONS: Regionalization reduced mortality and cost, indicating fewer complications, but paradoxically increased LOS. Further research is needed to explore the full impact on health care utilization.

BACKGROUND: Anaphylaxis is a severe and potentially fatal allergic response. Early-life exposure to rural environments may help protect against allergic reaction. This study assesses urban/rural differences by age and race/ethnicity in emergency department (ED) pediatric visit rates for food-induced anaphylaxis. METHODS: This observational study examined 2009-2014 inpatient and ED data from New York and Florida, using ICD-9-CM diagnostic code (995.6) to identify food-induced anaphylaxis cases <18 y/o. Primary predictor of interest was urban/rural setting, with race/ethnicity and age also evaluated. Associations between ED visit rates and urban/rural setting were evaluated by multivariable hierarchical negative binomial regression with state and year fixed effects. RESULTS: ED visit rates (per 100,000) for food-induced anaphylaxis were 12.31 and 4.60 in urban and rural settings, respectively. Rates were highest among Blacks (15.26) younger urban children (17.29) and older rural children (6.99). Compared to rural, urban children had significantly higher anaphalaxis ED visit rates (IRR 2.77). CONCLUSIONS: Food-induced anaphylaxis ED visit rates were highest among younger urban children and Black children, with a notable contrast in age distribution between urban and rural rates. Higher urban rates may be attributed to Hygiene Hypothesis, though racial, economic and emergency care access disparities may also influence these outcomes.

The purpose of the study is to examine (1) nationally representative incidence rates of Emergency Department (ED) visits due to sudden cardiac arrest (SCA) in pediatric and young adult populations, (2) basic characteristics of the ED visits with SCA, and (3) patient and hospital factors associated with survival after SCA. We used the Nationwide Emergency Department Sample from 2006 to 2013. ICD-9-CM diagnostic codes identified ED visits due to SCA for patients ≤ 30 years old. Outcomes included yearly incidence of ED visits for SCA, and survival to hospital discharge. Predictors of interest were age groups, sex, and SCA case volume. A logistic regression model adjusted by patient- and hospital-level variables was used. Stratified analyses of age by (< 12 and ≥ 12 years old) were performed to explore the effect of pubertal development on SCA. With 71,881 ED visits due to SCA, the total incidence rate was 6.9 per 100,000 population, with a mortality rate of 89.6% and male/female ratio of 1.7. With the adjusted regression models, there were no differences in survival rate by sex; however, when stratified at 12 years old, males were less likely to survive than females above 12 years old (odds ratio [OR] 0.71, P < 0.01), but not under 12 years old. No statistically significant differences in survival rates between low- and high-SCA volume EDs were detected (OR 1.03, P = 0.77). Data showed no benefit of regionalized care for post-SCA in ≤ 30-year-old populations. With further examination of the differences between sexes, new management strategies for SCA cases can be developed.
