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.

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.

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.

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.

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.

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.

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.

Associations between state-level severe maternal morbidity and other perinatal indicators.
This study used the HCUP State Inpatient Databases (HCUP-SID) to determine the correlation between state-level severe maternal morbidity (SMM) rates and perinatal indicators. HCUP-SID was analyzed from 2017 to 2019 using revised code sets for 20 indicators excluding blood transfusions. Perinatal indicators used included prepregnancy hypertension, prepregnancy diabetes, prepregnancy obesity, low-risk cesarean delivery, preterm birth, infant mortality, and maternal mortality. HCUP-SID data for 10,542,942 maternal deliveries and 11,394,752 live births from the National Vital Statistics System (NVSS) were aggregated for state-level analysis. SMM rates were significantly correlated with 2 of the 7 perinatal indicators: prepregnancy hypertension and low-risk cesarean deliveries. All other perinatal indicators were significantly associated with at least 4 of 7 other indicators, and most correlations were higher in magnitude. Maternity mortality rates were highest in the southeast.

Trends in severe maternal morbidity in the US across the transition to ICD-10-CM/PCS from 2012-2019.
This study evaluated national and state trends in severe maternal morbidity (SMM) rates from 2012 to 2019, and potential disruptions associated with the transition to International Classification of Diseases, 10th Revision, Clinical Modification and Procedure Coding System (ICD-10-CM/PCS) in October 2015. This repeated cross-sectional analysis examined delivery hospitalizations in the HCUP’s National Inpatient Sample and State Inpatient Databases. There were almost 6 million delivery hospitalizations in the national sample representing a weighted total of 29.8 million deliveries with a mean maternal age of 28.6 years. SMM rates increased from 69.5 per 10,000 deliveries to 79.7 per 10,000 in 2019 without a significant change across the ICD-10-CM/PCS transition. OF 20 SMM indicators, rates for 10 indicators increased while 3 significantly decreased with 5 of those changes associated with the ICD-10-CM/PCS transition. Acute kidney failure had the largest increase, from 6.4 to 15.3 per 10,000 delivery hospitalizations, with no change associated with ICD transition. Disseminated intravascular coagulation had the largest decrease from 31.3 to 21.2 per 10,000, with a significant drop associated with ICD transition. State SMM rates significantly decreased for 1 state and significantly increased for 21 states from 2012 to 2019 and with varying associations with ICD transition.

Severity of hospitalizations from SARS-CoV-2 vs influenza and respiratory syncytial virus infection in children aged 5 to 11 years in 11 US states.
By the time emergency use authorization had been granted for the Pfizer-BioNTech vaccine in October 2021 in children aged 5 to 11 years, there had been 1.8 million diagnoses of SARS-CoV-2 infection, 8,000 hospitalizations, and 143 deaths in that age group. Very little has been reported on the severity of those hospitalizations relative to the influenza virus and respiratory syncytial virus (RSV) which are the most common childhood viruses. The purpose of this study was to compare hospitalizations of children aged 5 to 11 for SARS-CoV-2 infection and multisystem inflammatory system in children (MIS-C, a sequela of COVID-19 disease) with the hospitalizations of children aged 5 to 11 years who were infected with influenza and RSV. The researchers utilized inpatient data from the Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project from the first 11 states with complete first-quarter data as of October 2021, representing 24% of the US population of children aged 5 to 11 years. The researchers examined 46 complications in 7 body systems, total care costs and charges, and data on race and ethnicity. The resulting cross-sectional study included patient data from a total of 2,269 children. The study found that COVID-19 hospitalizations occurred at the rate of 10.8 per 100,000 children, while Influenza and RSV were rare during the first quarter of 2021 with 23 total hospital discharges combined. However, in 2017, which researchers also measured for data on influenza and RSV, influenza and RSV had 17.0 and 6.2 hospitalizations per 100,000 children, respectively. Inpatient death for all viruses was rare. MIS-C had the highest rates of cardiovascular, hematologic, and gastrointestinal complications. Children with RSV ha the highest rate of respiratory complications. Children with COVID-19 (without MISC-C) had the highest rate of neurologic complications, whereas children with influenza had the highest rate of muscoskeletal complications. Children with MIS-C had the longest median length of stay at a median cost of $23,585 per stay compared to children with influenza with a median length of stay of 2 days and a cost of $5,200.

Preeclampsia predicts risk of hospitalization for heart failure with preserved ejection fraction.
Preeclampsia is associated with increased risk of future heart failure (HF), but the relationship between preeclampsia and HF subtypes are not well-established. The objective of this analysis was to identify the risk of HF with preserved ejection fraction (HFpEF) following a delivery complicated by preeclampsia/eclampsia. The investigators concluded that preeclampsia/eclampsia was an independent risk factor for future hospitalizations for HFpEF.

The inpatient burden and comorbidities of pyoderma gangrenosum in adults in the United States.
The objective of this study was to determine the prevalence, predictors, outcomes, and costs of hospitalization for pyoderma gangrenosum (PG) in United States adults. Data from the 2002-2012 National Inpatient Sample were analyzed. Findings showed that PG admissions were more likely at teaching and medium or large hospitals. The majority of inpatients with PG were classified with minor or moderate likelihood of dying, but moderate and major loss of function. PG was associated with numerous other health disorders. This study demonstrated a substantial and increasing inpatient burden of PG in the United States, with considerable disability and mortality risk, multiple comorbid health disorders, and costs.

Super fragmented: a nationally representative cross-sectional study exploring the fragmentation of inpatient care among super-utilizers.
Researchers sought to determine the prevalence of super-utilizers who receive fragmented care across different hospitals and to describe associated risks, costs, and health outcomes. Using HCUP data, they found that inpatient care fragmentation was common among super-utilizers and disproportionately affected vulnerable populations. It was associated with high yearly costs and a decreased probability of correctly identifying super-utilizers.

Neonatal abstinence syndrome and maternal opioid-Related diagnoses in the US, 2010-2017.
This study analyzed trends in neonatal abstinence syndrome (NAS) and maternal opioid-Related diagnosis (MOD) in the United States from 2010 to 2017. A cross-sectional analysis was done of the HCUP National Inpatient Sample and State Inpatient Database from 2010 through 2017. Diagnoses of NAS and MOD were found using the ICD-10, CM codes. Significant increases occurred in rates of NAS, from 4.0 to 7.3 per birth hospitalizations and MOD, from 3.5 to 8.2 per 1000 delivery hospitalizations. A census of 47 state databases in 2017 found a large range of NAS rates – from 1.3 per 1000 birth hospitalizations in Nebraska to 53.5 per 1000 hospitalizations in West Virginia with the same ranges found for MOD rates. In all states except Nebraska and Vermont which only had significant MOD increases, NAS and MOD rates rose significantly from 2010 to 2017.

Association of prurigo nodularis and lichen simplex chronicus with hospitalization for mental health disorders in US adults.
Prurigo nodularis (PN) and lichen simplex chronicus (LSC) are debilitating chronic pruritic diseases that can lead to and be exacerbated by psychosocial distress. However, little is known about the mental health (MH) comorbidities of PN/LSC. In this study, the investigators sought to evaluate the likelihood and cost-burden of MH comorbidities and emergencies associated with PN/LSC.

Geriatric syndrome risk factors among hospitalized postacute Medicare patients.
The purpose of this study was to assess the association of geriatric syndrome risk factors with postacute utilization among hospitalized Medicare patients (both Medicare Advantage [MA] and fee-for-service [FFS] cohorts) and to examine patterns of postacute care for MA and FFS cohorts with high geriatric syndrome risk. The investigators found that geriatric syndrome risk factors not only play a role in postacute care and inpatient utilization in MA and FFS cohorts but also explain different utilizations between MA and FFS cohorts.

Disparities in United States hospitalizations for serious infections in patients with and without opioid use disorder: a nationwide observational study.
This study examined the differences in patients with and without opioid use disorder (OUD) who were hospitalized for serious infections focusing on infective endocarditis, epidural abscess, septic arthritis or osteomyelitis. The authors used the 2016 National Inpatient Sample to examine differences in length of stay (LOS), discharge disposition, and charges. Patients with OUD had a lower probability of discharge at any given LOS, and lower odds of discharge to home with higher odds of discharge to a post-acute care facility. There were no significant differences in average total hospital charges.

Inpatient morbidity and mortality of measles in the United States.
This study examined measles hospitalizations from 2002-2006 using the Nationwide Inpatient Sample to assess complications and mortality. There were 1,018 measles hospitalizations during that time period. Measles and comorbidities were defined using ICD-9-CM or ICD-10-CM codes. Measles were associated with higher odds of gastrointestinal, hematologic, infection, neurologic, ophthalmologic, pulmonary and renal complications, with the strongest association observed with encephalitis. Thirty-four deaths were recorded with higher inpatient mortality for measles patients than those without measles.

Association of acute kidney injury with readmissions after hospitalization for acute exacerbation of chronic obstructive pulmonary disease: a population-based study.
This study examined the association between acute kidney injury (AKI) and readmission with hospitalization for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Retrospective, population-based cohort data was used from the HCUP State Inpatient Databases from seven states (Arkansas, California, Florida, Iowa, Nebraska, New York, and Utah) from 2010 through 2013. A total of 356,990 patients were identified as hospitalized for AECOPD. Median age was 71 years and 41.9% were male. Of those 7% had a concurrent diagnosis of AKI. Patients with AKI were found to have a significantly higher risk of 30-day all-cause readmission compared to those without AKI as well as a significantly higher risk of 90-day all-cause readmission, particularly for non-respiratory reasons. These reasons included sepsis, acute renal failure, and congestive heart failure.

Trend of surgery for orbital cellulitis: an analysis of state inpatient databases.
This study examined trends in surgery for orbital cellulitis from 2008 to 2015. Retrospective data was extracted from AHRQ’s State Inpatient Databases (SIDs) and patients with an ICD9-CM diagnosis code for orbital cellulitis were identified from Arkansas, Florida, Iowa, Maryland, Nebraska, New York and Wisconsin. The number of hospitalizations declined from a high of 1,574 down to 865 in 2014. The number of surgeries ranged from 103 to 154 from 2008 to 2015. For children, surgery was associated with age, ophthalmologic cormobidity, and conjunctival edema. For adults - male gender, private insurance, optic neuritis, and cranial nervs III/VI/VI palsy were associated with surgery.

Association of obstructive sleep apnea with severity of patients hospitalized for acute asthma. Ann Allergy Asthma Immunol 2020 Feb;124(2):165-70.e4. doi: 10.1016/j.anai.2019.11.002.
Researchers investigated the association of obstructive sleep apnea (OSA) with acute asthma severity in a retrospective cohort study that used State Inpatient Databases from eight geographically diverse states. Outcomes examined were markers of acute severity such as mechanical ventilation use, hospital length of stay, and in-hospital mortality. The researchers found that, among patients hospitalized for acute asthma, OSA was associated with a higher risk of noninvasive positive pressure ventilation use and longer length of stay compared with those without OSA.

Trends in US physician diagnosis of child physical abuse and neglect injuries, 2006-2014.
The purpose of this study was to determine if US child physical abuse and neglect injury rates changed from 2006 to 2014, whether definitive diagnoses of physical abuse and neglect were used more often over time, and what patient factors influenced definitive physical maltreatment diagnoses. The investigators found that definitive diagnoses of physical abuse and neglect increased over the study period and were associated with hospital volume and patient characteristics which may reflect provider experience and possible bias.

Hospitalizations associated with respiratory syncytial virus and influenza in children, including children diagnosed with asthma.
This study examined hospitalization rates in children associated with respiratory syncytial virus (RSV) and influenza, including children with asthma. HCUP hospitalization data and additional data to estimate RSV and influenza-associated hospitalization with a respiratory cause was analyzed in different subpopulations of US children between 2003 and 2010. Annual rates of RSV-associated hospitalization was highest in infants and young children, and declined rapidly with age. Influenza hospitalizations also were highest in young children and declined by age 12-17 years. Higher rates of RSV-related and influenza hospitalization in the youngest children with a prior diagnosis of asthma was also found.
