Association of neighborhood opportunity and pediatric hospitalization rates in the United States.
This study 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. 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, which measures at 21.02 hospitalizations per 1000. Adjusted hospitalization rates decreased significantly and in a stepwise fashion as COI increased, from 26.56 per 1000 in very low COI areas to 14.76 per 1000 in very high COI areas (incidence rate ratio 1.8). Decreasing neighborhood opportunity was associated with increasing hospitalization rates among children in the study.

Burden of serious harms from diagnostic error in the USA.
Americans who experience serious harm from misdiagnosis annually. Serious harm is defined as permanent morbidity or morality. This cross-sectional analysis used nationally representative observational data. The authors estimated annual incident vascular events and infections from 21.5 million (M) sampled US hospital discharges (2012-2014). US-based cancer registries were used to find annual new cancers. They derived diagnostic errors and serious harms by multiplying by literature-based rates for disease-specific incidences for 15 major vascular events, infections and cancers ('Big Three' categories). Extrapolating to all diseases (including non-'Big Three' dangerous disease categories), they estimated total serious harms annually in the USA to be 795,000 (plausible range 598,000-1,023,000). Using more conservative assumptions they estimated 549,000 serious harms. These results were compatible with setting-specific serious harm estimates from inpatient, emergency department and ambulatory care. Fifteen dangerous diseases accounted for 50.7% of total serious harms and the top 5 (stroke, sepsis, pneumonia, venous thromboembolism and lung cancer) accounted for 38.7%.

Secondary undertriage of pediatric trauma patients across the United States emergency departments.
The term “Undertriage” refers to the treatment of patients at facilities lacking in the equipment needed to treat the patient's injuries appropriately. The purpose of this retrospective cohort study was to assess the relationship between patient and hospital characteristics and secondary undertriage in children after major trauma. The researchers utilized the 2019 Nationwide Emergency Department Sample and included patients aged less than 18 years of age if they presented to a Level 3 or non-trauma center (NTC) and were diagnosed with a traumatic injury with an injury severity score of greater than 15 based on International Classification of Diseases 10 codes. The study found that of 6,572 weighted patients, 15% were undertriaged. Undertriage was significantly associated with older age, metropolitan location, and major abdominal injuries. After multivariable adjustment, secondary undertriage was significantly associated with patients aged 6-10 years of age compared to patients aged 15-17 years, penetrating injury, major chest injury, and presentation at a teaching hospital.

COVID-19 admission rates and changes in US hospital inpatient and intensive care unit occupancy.
The objective of this cross-sectional study was to measure the relationship between COVID-19 admission rates and hospital occupancy in different US areas at different time periods during 2020. Data were taken from the HCUP State Inpatient Databases for patients in nonfederal acute care hospitals. The results showed that hospital occupancy decreased during weeks with low COVID-19 admissions and increased during weeks with high COVID-19 admissions; the largest changes occurred early in the pandemic. The authors concluded that their findings suggest that COVID-19 surges strained intensive care unit capacity and were associated with decreases in the number of surgical patients. These occupancy fluctuations may have affected quality of care and hospital finances.

Effects of the COVID-19 early pandemic on delivery outcomes among women with and without COVID-19 at birth.
This AHRQ-authored paper examined the early pandemic-related changes in birth outcomes for pregnant women with and without a COVID-19 diagnosis at delivery. They compared four delivery outcomes-preterm delivery (PTD), severe maternal morbidity (SMM), stillbirth, and cesarean birth-between 2017 and 2019 (prepandemic) and between April and December 2020 (early pandemic) using interrupted time series models on 11.8 million deliveries, stratified by COVID-19 infection status at birth with entropy weighting for historical controls, from the HCUP across 43 states and the District of Columbia. Relative to 2017-2019, women without COVID-19 at delivery in 2020 had lower odds of PTD (OR = 0.93) and SMM (OR = 0.88) but increased odds of stillbirth (OR = 1.04). COVID-19 deliveries had an excess of each outcome, by factors of 1.07-1.46 for outcomes except SMM at 4.21. The effect for SMM was more pronounced for Asian/Pacific Islander non-Hispanic (API; OR = 10.51) and Hispanic (OR = 5.09) pregnant women than for White non-Hispanic (OR = 3.28) women.

Estimating state-specific population-based hospitalization rates from in-state hospital discharge data.
The purpose of this study was to develop weights to estimate state population-based hospitalization rates for all residents of a state using only data from in-state hospitals. The researchers utilized Agency for Healthcare Research and Quality, Healthcare Cost and Utilization Project (HCUP), State Inpatient Databases (SID), for data from 2018-2019, including 47 states plus Washington D.C. and excluding residents treated in other states. SID were based on administrative billing records collected by hospitals, shared with statewide data organizations, and provided to HCUP. The study found that of 34,186,766 discharged patients in 2018, 4.2% were movers. A greater share of movers (vs. stayers) lived in state border and rural counties; a lower share had discharges billed to Medicaid or were hospitalized for maternal/neonatal services. The difference between 2019 observed and estimated total discharges for all included states and D.C. was 9,402. The researchers reported an overestimation of discharges with an expected payer of Medicaid, from the lowest income communities, and for maternal/neonatal care. The researchers reported an underestimation of discharges with an expected payer of private insurance, from the highest income communities, and with injury diagnoses and surgical services. Estimates for the majority of subsets were reported to be not within a 95% confidence interval, attributed to factors such as hospital closures/openings, shifting consumer preferences, and other issues impossible to account for.

Pediatric hospitalization trends at children's and general hospitals, 2000-2019.
The purpose of this study was to examine whether pediatric inpatient care has been redistributed from general hospitals into children’s hospitals (CHs). The researchers utilized the AHRQ Kids’ Inpatient Database (KID) to identify inpatient nonbirth discharges for children younger than 18 years from 2000 to 2019. The study included 14.758,391 discharges and found that annual inpatient discharges decreased by 26.5% from 2000 to 2019, while the percentage of total national discharges from CHs increased significantly, from 58.9% in 2000 to 81.8% in 2019. Discharges from freestanding CHs increased from 19.3% to 34.2%, those at non-freestanding CHs increased from 39.6% to 47.6%, and percentage of discharges from non-CHs decreased from 41.1%. An increase in inter-facility transfer (IFT) accompanied the changes in the distribution of pediatric discharges. In 2000, 6.1% of total discharges were transferred from one facility to another before discharge; in 2019, 18.8% experienced an IFT. Of children experiencing an IFT in 2019, 88.0% were transferred to a CH.

Association of intellectual disability with delayed presentation and worse outcomes in emergency general surgery.
Individuals with intellectual disabilities may be at higher risk of delayed presentation and worse outcomes for emergency general surgery (EGS) conditions. The purpose of this study was to explore the relationship between intellectual disability and both severity of disease and clinical outcomes in patients presenting with typical EGS conditions. The study found that of 1,317,572 adult EGS admissions, 0.38% of patients had an ICD-9/-10 code consistent with current intellectual disability. EGS patients with intellectual disabilities had 31% greater odds of more severe disease at presentation when compared with neurotypical patients. Intellectual disability was also related with a higher likelihood of complications and mortality, longer lengths of stay, lower rate of discharge to home, and higher inpatient costs.

Critical revisits among children after emergency department discharge.
This retrospective study’s objectives were to determine the rate of critical emergency department (ED) revisits among children discharged from the ED and to identify factors associated with critical revisits. Using the HCUP State ED Databases (SEDD) and State Inpatient Databases (SID), researchers examined data from six states, including patients under 21 years old. The findings indicated that critical ED revisits after discharge were uncommon and patient death within three days of ED discharge were rare; patients with complex chronic conditions were more likely to have a critical ED revisit. The researchers concluded that future research should focus on understanding higher risk among patients with asthma or a history of complex chronic conditions.

Association of hospital discharge against medical advice and coded housing instability in the US.
This study examined the relationship between discharge type and housing instability, then identified primary reasons for hospitalization among self-discharged patients with housing instability. This cross-sectional, retrospective study analyzed the National Inpatient Sample between January 2017 and December 2019, available from the Agency for Healthcare Research and Quality’s Healthcare Cost and Utilization Project. Among 85,402,831 hospitalizations analyzed, 1.6% resulted in self-discharge. Compared to admissions with planned discharges, self-discharges were more likely to have coded housing instability. Among hospitalizations resulting in self-discharge, admissions with coded housing instability were more likely to result in self-discharge than those without coded housing instability. Relationships between housing instability and self-discharges were found among major medical conditions: septicemia, acute myocardial infarction, and respiratory failure. Alcohol-related disorders and opioid-related disorders were among the highest self-discharge volumes, but relationships were minimal.

Socioeconomic factors are associated with severity of hospitalization in pediatric lupus: an analysis of the 2016 Kids' Inpatient Database.
This study’s goal was to investigate the relationship of income level and other socioeconomic factors with length of stay (LOS) in the hospital and severe lupus features using the 2016 Kids' Inpatient Database (KID). The cohort included children aged 2-20 identified with lupus hospitalization in the 2016 KID using International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) codes (M32). A total of 3,367 unweighted lupus hospitalizations were identified. Income level was found to be a statistically significant predictor of increased LOS in the hospital for those in the lowest income quartile. Black race, "other" race, and public insurance were also associated with severe lupus features.

Impact of Medicaid expansion on outcomes after abdominal aortic aneurysm repair.
Researchers sought to assess the association between Medicaid expansion and outcomes after abdominal aortic aneurysm repair using HCUP State Inpatient Databases data from 14 states. They examined data on 8995 adult patients under age 65 from both non-expansion states and Medicaid expansion states. The results indicated that Medicaid expansion was associated with decreased in-hospital mortality after abdominal aortic aneurysm repair among all patients, particularly among patients who were either on Medicaid or were uninsured. The researchers concluded that these results provided support for improved access to care for patients undergoing abdominal aortic aneurysm repair through Medicaid expansion.

Racial and ethnic disparities among patients hospitalized for acute cholangitis in the United States.
Researchers used HCUP NIS data to analyze hospitalizations from 2009-18 to determine whether race/ethnicity is associated with hospitalization outcomes among patients admitted with acute cholangitis. Their analysis included patients aged 18 or older who were hospitalized with an ICD9/10 diagnosis of cholangitis. Results indicated that black patients had higher in-hospital mortality rates, were associated with fewer and delayed endoscopic retrograde cholangiopancreatography (ERCP) procedures, and had longer length of stay. The researchers concluded that future studies with more granular social determinants of health data should explore underlying reasons for these disparities to develop interventions aimed at reducing racial disparities in outcomes among patients with acute cholangitis.

Temporal trends in postoperative and ventilator-associated pneumonia in the United States.
The purpose of this retrospective cohort study was to assess change in rates of postoperative pneumonia and ventilator-associated pneumonia among patients hospitalized in the United States during 2009-2019. The study found that among 58,618 patients undergoing major surgical procedures between 2009 and 2019, the observed rate of postoperative pneumonia from 2009-2011 was 1.9% and decreased to 1.3% during 2017-2019. The adjusted annual risk each year, compared to the prior year, was 0.94. Among 4,007 patients hospitalized for any of the 4 conditions at risk for ventilator-associated pneumonia during 2009-2019, the researchers did not detect a significant change in observed or adjusted rates. Observed rates clustered around 10%, and adjusted annual risk compared to the prior year was 0.99.

The Impact of the Affordable Care Act Insurance Expansions on Opioid-Related Emergency Department Visits.
The authors leveraged ACA coverage expansions, including Medicaid expansion and Marketplaces, to study the impact of health insurance on opioid-related emergency department (ED) visits. They used ZIP-code–level ED utilization data from HCUP’s State Inpatient Databases (SID) and State Emergency Department Databases (SEDD) for 29 states. They found evidence of a dose-response relationship between pre-ACA uninsured and changes in ED visit rates in both expansion and non-expansion states: areas with higher uninsured rates prior to ACA saw larger reductions in opioid-related ED visits after the ACA took effect. The authors concluded that these findings suggest that increased insurance coverage may to help mitigate the opioid crisis.

Association of homelessness with emergency department use among children in New York.
This research letter describes a cross-sectional study that was conducted to evaluate the association of homelessness with emergency department (ED) use among children in New York. The study used the HCUP State Emergency Department Database and State Inpatient Database for New York including children 18 years and younger with an ED visit between 2014 and 2018. The primary outcome was frequent ED use, defined as 4 or more visits per calendar year. The authors determined visit incident rates for all children for ambulatory care-sensitive conditions (asthma, diabetes, gastroenteritis, urinary tract infection), injuries and poisonings, and mental health problems based on ICD-9 and ICD-10 codes. Frequent ED use was more common among children experiencing homelessness, occurring in 22.1% vs 4.3% of children who were housed. Children experiencing homelessness had higher incidences of asthma, diabetes, urinary tract infections, and mental health problems and lower incidences of injuries and poisonings, which lead to higher admission rates overall (42.1% vs 0.7%) and to ICUs (4.1% vs 0.7%). Admission rates were higher across all diagnoses and to ICUs for asthma, gastroenteritis, and injuries and poisonings. ED usage rates were highest for homeless children aged 12-17 (40.2% of all children).

The association of missed nursing care with very low birthweight infant outcomes.
This study examined the association of missed nursing care and health outcomes of very low birthweight (VLBW) infants in neonatal intensive care units (NICUs). The authors used 2016 hospital administrative discharge abstracts for VLBW newborns (n = 7,595) and NICU registered nurse survey responses (n = 6,963) from the National Database of Nursing Quality Indicators. Mortality, morbidity, and length of stay (LOS) was examined in 190 sample hospitals from 19 states in all regions. There was a significant association between higher odds of bloodstream infection and longer LOS, but not mortality or severe intraventricular hemorrhage and missed nursing care.

Sociodemographic differences of hospitalization and associations of resource utilization for failure to thrive.
The objective of this study was to examine sociodemographic differences between elective and nonelective admissions for failure to thrive. Researchers investigated associations between admission type and hospital resource utilization, including length of stay and feeding tube placement. The study included data on children less than 2 years old with failure to thrive in the Kids' Inpatient Database. The findings showed differences by race and ethnicity, income, and insurance type, among other factors. Nonelective admissions had higher proportions of infants who were Black, Hispanic, and of lower-income, and were associated with longer lengths of stay. The researchers concluded that future research is needed to elucidate drivers of these differences, particularly those related to racial and ethnic disparities and structural racism.

This study evaluated regional center transfer rates, turndown rates, and outcomes for Black vs White patients presenting with ruptured abdominal aortic aneurysms (rAAAs) in two large databases. All rAAA repairs in the Vascular Quality Initiative from 2003 to 2020 was used. The authors used the National Inpatient Sample from 2004 to 2015 to examine turndown rates for repair. They identified 4935 patients with rAAAs in the Vascular Quality Initiative (6.2% Black) and 48,489 in the National Inpatient Sample (6.0% Black). Transfer rates were high; however, Black patients were significantly less likely to undergo transfer before repair compared with White patients (49% Black vs 62% White). No significant differences were found in perioperative mortality or complications. However, Black patients were significantly more likely to be turned down for repair (37% vs 28%). This difference was mostly found to be due to insurance status. Patients with private insurance had undergone surgery at a similar rate. However, among patients with Medicare or Medicaid/self-pay, Black patients were less likely than were White patients to undergo repair (Medicare, 64% vs 72%; Medicaid/self-pay, 43% vs 61%). Medicaid/self-pay patients were less likely to undergo repair than were patients of the same race with either Medicare or private insurance.

Complications, adverse drug events, high costs, and disparities in multisystem inflammatory syndrome in children vs COVID-19.
This cross-sectional study’s goal was to determine outcomes from multisystem inflammatory syndrome in children (MIS-C) after COVID-19. Outcomes examined were 50 complications, adverse medication events, costs, and the Social Vulnerability Index. An analysis was conducted using data from the 2021 HCUP in individuals younger than 21 years from 31 states. There were 4107 individuals hospitalized with MIS-C (median age 9 years, 59.5% male, 38.1% White) and 23,686 hospitalizations for COVID-19 without MIS-C (median age 15 years, 54.5% female, 44.1% White). Hospitalization rate for MIS-C was 1.48 per 100,000 children, ranging from 0.97 hospitalizations per 100 for White and 1.99 hospitalizations per 100 for Black children. Outcomes were worse when organ dysfunction increased from 2 to 8 organs, with deaths increasing from less than 1% to 5.8% for MIS-C, and 1% to 17.2% for COVID-19. Median length of stay increased from 4 to 8 days for MIS-C, and 3 to 16 days for COVID-19. Median costs for MIS-C increased from $16,225 to $53 359 and from $6474 to $98,643 for COVID-19. The percentage of MIS-C cases in Black children doubled from 16.2% to 31.7% as organ dysfunction increased, remaining unchanged with COVID-19.

Medicaid expansion led to reductions in postpartum hospitalizations.
The purpose of this study was to assess whether the Medicaid expansions of the Affordable Care Act (ACA) affected rates of postpartum hospitalization. The researchers compared states that did and did not expand Medicaid under the ACA as they related to changes in hospitalizations among birthing people with a Medicaid-financed delivery. The study found a 17% reduction in hospitalizations during the first 60 days postpartum associated with the Medicaid expansions, and evidence of a lesser decrease in hospitalizations between 61 days and 6 months postpartum. The researchers concluded that Medicaid coverage expansion under the ACA resulted in improved postpartum health for low-income birthing people.

Racial and ethnic disparities in preventable hospitalizations and ED visits five years after ACA Medicaid expansions,.
This AHRQ-authored paper examined whether the 2014 Affordable Care Act (ACA) Medicaid expansions mitigated existing racial or ethnic disparities in preventable hospitalizations and emergency department (ED) visits. The authors used inpatient data from twenty-nine states and ED data from twenty-six states for the period 2011 to 2018. They found that Medicaid expansions decreased disparities in preventable hospitalizations and ED visits between non-Hispanic Black and White nonelderly adults by 10 percent or more. There were no significant effects on disparities between Hispanic and non-Hispanic White nonelderly adults. Their findings highlight sustained improvements in community-level care for non-Hispanic Black populations, but also suggest access barriers experienced by Hispanic adults that need to be addressed beyond Medicaid eligibility expansion.

Intermediate or intensive care unit admission across race and ethnicity.
This study’s aim was to assess the association between race and ethnicity and admission to intermediate (IMCUs) or intensive care units (ICUs) among hospitalized patients. Florida hospital discharge data from the State Inpatient Database was used to assess the relationship between race (White, Black, Other) and Hispanic ethnicity and IMCU or ICU admission. After controlling for demographics and comorbidities, the prevalence of IMCU or ICU admission was higher among non-Hispanic Blacks and non-Hispanic patients of other races compared with non-Hispanic Whites. The prevalence of IMCU or ICU use was lower among Hispanic Whites and Hispanics of other races compared with non-Hispanic Whites after controlling for other demographic characteristics and comorbidities.

Severe maternal morbidity and mortality risk at the intersection of rurality, race and ethnicity, and Medicaid.
Using maternal discharge records from childbirth hospitalizations in the HCUP National Inpatient Sample, 2007-15, researchers examined differences in rates of severe maternal morbidity and mortality by rural or urban geography, race and ethnicity, and clinical factors among Medicaid-funded births and privately insured hospital births. The highest rate of severe maternal morbidity and mortality occurred among rural Indigenous Medicaid-funded births; births among Black rural and urban residents and among Hispanic urban residents also experienced elevated rates. The researchers concluded that heightened rates of severe maternal morbidity and mortality among Medicaid-funded births indicate an opportunity for state and federal policy responses to address the maternal health challenges faced by Medicaid beneficiaries, including Black, Indigenous, and rural residents

New evidence on geographic disparities in United States hospital capacity.
The purpose of this study was to describe hospital capacity across the United States. The researchers combined American Hospital Association Survey, Hospital Compare, and American Community Survey data with the 2017 near-census of U.S. hospital inpatient discharges from the Healthcare Cost and Utilization Project (HCUP). The study found that 0.11 more beds per 1000 population were supplied to zip codes where Non-Hispanic individuals live than zip codes where non-Hispanic White individuals live. However, the hospitals supplying this capacity have 0.36 fewer staff per bed and perform worse on many care quality measures. Zip codes in the most urban parts of America have the least hospital capacity (2.11 beds per 1000 persons) from across the rural-urban continuum. While more rural areas have higher capacity levels, urban areas have advantages in staff and capital per bed. The researchers did not find systematic differences in care quality between rural and urban areas. The study concluded that lower hospital care quality and resource intensity plays a key role in racial, ethnic, and income disparities in hospital care related outcomes.
