Trends in treatment costs of U.S. emergency department visits.
In recent years, emergency department (ED) spending has been increasing more than in other areas of health care. Few studies have focused on changes in ED treatment costs. The purpose of this study was to analyze recent increases in emergency department treatment costs to highlight possibilities for reducing the growth of overall hospital costs. The researchers used data from the Healthcare Cost and Utilization Project (HCUP) and applied Cost-to-Charge Ratios for ED Files to the HCUP Nationwide Emergency Department Sample for 2012 through 2019. The study found that ED treatment costs experienced a 5.4% annual growth rate, increasing from $54 billion to $88 billion, with higher treatment cost per visit responsible for 4.4 of those percentage points. The researchers concluded that the study provides valuable information for decision- and policy-makers by bringing attention to components of the healthcare delivery system with the highest increasing costs as well as trends in overall ED costs.

Combined impact of medicare's hospital pay for performance programs on quality and safety outcomes is mixed.
The authors examined the combined impact of Medicare's pay for performance (P4P) programs on clinical areas and populations targeted by the programs, as well as those outside their focus. Using HCUP data, and consistent with previous studies for individual programs, they detected minimal, if any, effect of Medicare's hospital P4P programs on quality and safety. They recommended a redesigning of the P4P programs before continuing to expand them.

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 and distribution of in-hospital mortality among pregnant and postpartum individuals by pregnancy period.
The purpose of this study was to examine long-term trends in inpatient death rates among pregnant and postpartum individuals and proportion of deaths by pregnancy period (antenatal, delivery, and postpartum). The researchers examined patterns of inpatient mortality during pregnancy-associated hospitalizations utilizing data from the National Inpatient Sample for 1994 to 2015 and 2017 to 2019. The study found that between 1994 and 2015, among 84,181,338 hospitalizations an estimated 12,654 inpatient deaths occurred among pregnant and postpartum individuals with a mean age of 29.37. Inpatient deaths during delivery hospitalizations decreased from 10.6 deaths per 100 000 delivery hospitalizations to 4.7 deaths per 100 000 delivery hospitalizations between 1994 to 1995 and 2014 to 2015. The rate of inpatient deaths in antenatal and postpartum periods remained unchanged between 1994 to 1995 and 2014 to 2015. The researchers concluded that resources directed toward improving quality of care at obstetric delivery have been associated with decreased rates of severe morbidity and may be associated with decreased mortality, but additional efforts need to be directed toward antenatal and postpartum hospitalizations.

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.

Incorporating harms into the weighting of the revised Agency for Healthcare Research and Quality Patient Safety for Selected Indicators Composite (Patient Safety Indicator 90).
The purpose of this study was to reweight AHRQ’s Patient Safety for Selected Indicators Composite (Patient Safety Indicator 90) from weights based solely on the frequency of component Patient Safety Indicators (PSIs) to those that incorporate excess harm reflecting patients' preferences for outcome-related health states. Findings showed that including harms in the weighting scheme changed individual component weights from the original frequency-based weighting. In the reweighted composite, PSIs 11, 13, and 12 contributed the greatest harm. The investigators concluded that reformulation of PSI 90 with harm-based weights is feasible and results in satisfactory reliability and discrimination.

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.

Quality of care for gallstone pancreatitis-the impact of the acute care surgery model and hospital-level operative resources.
This study aimed to determine the influence of structure and process related to operating room access on achieving index cholecystectomy for gallstone pancreatitis. In 2015, 2811 US hospitals on acute care surgery practices were surveyed, including infrastructure for operative access, with 1690 hospitals (60%) responding. The authors identified patients ≥ 18 years who were admitted with gallstone pancreatitis. Over the study period, 5656 patients were admitted with gallstone pancreatitis, and 70% had an index cholecystectomy. High-performing hospitals had an index cholecystectomy rate of 84.1%, compared to 58.5% at low-performing hospitals. High-performing hospitals were associated with teaching, and access to dedicated daytime operative resources.

Association of county-level availability of pediatricians with emergency department visits.
This study examined whether children in counties with more pediatricians had fewer emergency department (ED) visits. The authors conducted a cross-sectional study of all ED visits among children younger than 18 years from 6 states. Each additional pediatrician per 1000 children was associated with a 13.7% decrease in ED visits in the state-adjusted model. In the full model however, there was no association. Other factors such as presence of an urgent care facility, high socioeconomic status, urban status and higher proportions of White race and nonpublic insurance were also associated with decreased ED visit rates.

Association of Medicaid expansion under the Affordable Care Act with access to elective spine surgical care.
This study's goal was to evaluate the impact of Medicaid expansion under the Affordable Care Act on the volume and payer mix of elective spine surgery in the United States. The authors evaluated elective spinal surgeries performed in the U.S. from 2011 to 2016 and included 10 states with expanded Medicaid access and 4 states that did not. They identified 218,648 surgical procedures performed in 10 Medicaid expansion states and 118,693 procedures performed in 4 nonexpansion states. Medicaid expansion was associated with a 17% increase in mean hospital spine surgical volume and a 23% increase in Medicaid volume. Privately insured surgical volumes did not change significantly. This increase indicated improved access to care.

Contributors to disparities in postpartum readmission rates between safety-net and non-safety-net hospitals: a decomposition analysis.
The authors assessed how patient, hospital, and community characteristics explain the safety-net hospital (SNH)/non-SNH disparity in postpartum readmission rates. Using HCUP data, they found that higher postpartum readmission rates at SNHs versus non-SNHs were largely due to differences in the patient mix rather than hospital factors. They recommended hospital initiatives to reduce the risk of postpartum readmissions among SNH patients. They concluded that improving factors that contribute to the disparity, including underlying health conditions and health inequities associated with race, will require enduring investments in public health.

Association of socioeconomic characteristics with where children receive emergency care.
This study’s objective was to characterize national associations of neighborhood income and insurance type for children with the characteristics of emergency departments (EDs) from which they receive care. The authors conducted a cross-sectional study of ED visits by children from 2014 to 2017 using the Nationwide Emergency Department Sample. Emergency department characteristics were characterized by pediatric volume category. There was a total of 107.6 million ED visits from 2014 to 2017. Children outside of the wealthiest neighborhood income quartile had lower proportions of visits to high-volume pediatric EDs and greater proportions of visits to low-volume pediatric EDs than children in the wealthiest quartile. Publicly insured children were modestly more likely to visit higher-volume pediatric EDs than privately insurance and uninsured children. This association appears to be principally driven by urban-rural differences in access to pediatric emergency care.

General surgeon involvement in the care of patients designated with an American Association for the Surgery of Trauma-endorsed ICD-10-CM emergency general surgery diagnosis code in Wisconsin.
The authors sought to: (1) translate previously-developed ICD-9-CM diagnosis codes representing emergency general surgery (EGS) conditions to ICD-10-CM codes and (2) determine the national burden of and assess surgeon involvement across EGS conditions. They found that, of the seven most common EGS diagnoses, surgeon involvement was highest for appendicitis and biliary tract disease. For the other five most common conditions, surgeons were involved in roughly 20% of patient care episodes.

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.

Effects of hurricanes on emergency department utilization: an analysis across 7 US storms.
This study examines changes in emergency department (ED) utilization for residents of 344 counties after the occurrence of 7 US hurricanes between 2005 and 2016. Using HCUP data, findings showed that the overall population rate of weekly ED visits changed little post-hurricane, but rates by disease categories and age demonstrated varying results. ED utilization rates for respiratory disorders exhibited the largest post-hurricane increase, especially 2-3 weeks following the hurricane. The change in population rates by disease categories and age tended to be higher for people residing in counties closer to the hurricane path.

Emergency department visits for suicidal ideation and self-harm in rural and urban youths.
The authors sought to compare emergency department (ED) visit rates for suicidal ideation and/or self-harm among youth by urban-rural location of residence. Data was taken from the Nationwide Emergency Department Sample. They found that, compared with youths living in urban areas, youths living in rural areas had higher ED visit rates for self-harm, including self-inflicted firearm injuries. The researchers recommended preventive approaches for self-harm based in community and ED settings in order to help address these differences.

Access to obstetric, behavioral health, and surgical inpatient services after hospital mergers in rural areas.
This study examined the influence of rural hospital mergers on changes to inpatient service lines at hospitals and within their catchment areas. The authors used hospital discharge data from 32 HCUP Inpatient Databases from 2007 to 2018. They found that merged hospitals were more likely than independent hospitals to eliminate maternal/neonatal and surgical care. They also found that while the number of mental/substance use disorder-related stays decreased or remained stable at merged hospitals and their catchment areas, it increased for unaffiliated hospitals and their catchment areas. This indicates a potential unmet need in the communities of rural hospitals postmerger.

Methods for estimating the cost of treat-and-release emergency department visits.
The objective of this study was to evaluate and compare approaches to estimating the service delivery cost of emergency department (ED) visits from total charge data only. The investigators concluded that when cost-center-level charge detail for ED visits is unavailable, alternative methods relying on total ED charges can estimate ED service costs for patient and hospital segments.

Association of obstructive sleep apnea with all-cause readmissions after hospitalization for asthma exacerbation in adults aged 18-54 years: a population-based study, 2010-2013.
The authors sought to investigate associations between obstructive sleep apnea (OSA) and readmission risk after hospitalization for asthma exacerbation using data from State Inpatient Databases from seven U.S. states. They found that, overall, OSA was associated with a significantly higher incident rate of all-cause readmission. Additionally, OSA was associated with higher incident rates of readmissions for five major diseases: asthma, COPD, respiratory failure, pneumonia, and congestive heart failure, compared to non-OSA.

Quality of care before and after mergers and acquisitions of rural hospitals.
Researchers sought to examine changes in quality of care for patients at rural hospitals that merged compared with those that remained independent. Using HCUP data, they found that rural hospital mergers were associated with better mortality outcomes for acute myocardial infarction, heart failure, stroke, gastrointestinal hemorrhage, hip fracture, and pneumonia. They concluded that their finding is important to enhancing rural health care and reducing urban-rural disparities in quality of care.

Neonatal abstinence syndrome and maternal opioid-related diagnoses: analysis of ICD-10-CM transition, 2013-2017.
Researchers sought to evaluate whether the transition from ICD-9-CM to ICD-10-CM may have affected surveillance on rates of neonatal abstinence syndrome (NAS), maternal opioid use disorder (OUD), and opioid-related diagnoses. Using HCUP data, they found that the ICD-10-CM transition did not appear to affect NAS. However, coding of maternal OUD alone may not capture the same population across the transition, potentially confounding the interpretation of trend data spanning this time period.

The impact of urgent care centers on nonemergent emergency department visits.
This study looked at the impact of urgent care centers on nonemergency emergency department (ED) use. Secondary data from a novel urgent care center database, linked to the HCUP State Emergency Department Databases (SEDD) from six states was used. Data from ZIP codes with no urgent care centers served as a control group compared to areas with local urgent care centers. Having an open urgent care center in a ZIP code reduced the total number of ED visits by residents by 17.2% largely due to visits for less urgent conditions. The effect was concentrated in areas with hospitals with the longest ED wait times. The total number of uninsured visits to the ED were reduced by 21% and for Medicaid visits by 29.1%.

Patient insurance status is associated with care received after transfer among pediatric patients in the emergency department.
The objective of this study was to determine whether frequency of interfacility transfer varied by insurance status among pediatric emergency department (ED) patients. Secondarily, the investigators tested for an association between insurance status and odds of transfer with discharge from the second ED without observation or admission. The investigators concluded that among ED-to-ED transfers, pediatric patients with public or without insurance were more often kept for observation or admission at the second hospital after transfer.
