A standardized emergency department order set decreases admission rates and in-patient length of stay for adults patients with sickle cell disease.
The purpose of this 3-year prospective analysis study was to assess a quality improvement project to standardize Emergency Department (ED) care for patients presenting with pain associated with sickle cell disease (SCD). IN 2019 the researchers implemented an ED order set in to improve care and provide adequate management of analgesia. The primary outcome was the overall hospital admission rate for patients after the intervention, and the secondary outcome measures included ED disposition, rate of return to the ED within 72 hours, ED pain scores at admission and discharge, ED treatment time, in-patient length of stay, non-opioid medication use, and opioid medication use. The study found an overall 67% reduction in the hospital admission rate after implementation of the order set and a significant decrease in the percentage admission rate month over month. Time to the first non-opioid analgesic decreased by 71 minutes and there was no change in time to the first opioid medication. The rate of return to the ED within 72 hours did not change and the ED elopement rate did not change. There were significant increases in the prescribing of orally administered acetaminophen, celecoxib, and tizanidine, and intravenous ketamine and ketorolac. ED pain scores at discharge did not change for hospital-admitted and non-admitted patients. The possible reduction in costs was $193,440 during the 12-month observation period, and the average cost per visit decreased by $792. The researchers concluded that the ED order set decreased the rate of hospital admissions and the timeliness of analgesia administration without having a negative impact on the pain of the patients.

Disparities in adverse event reporting for hospitalized children.
The authors compared the adverse event (AE) rate identified by voluntary event reporting (VER) with that identified using the Global Assessment of Pediatric Patient Safety (GAPPS) between hospitalized children by weight category, race, and English proficiency. In the population studied, they identified 288 total AEs, 270 by the GAPPS and 18 by VER. They found a disparity in AE reporting for children with limited English proficiency, with fewer AEs by VER compared with no difference in AEs by GAPPS. They identified no disparities by weight category or race. They concluded that voluntary event reporting may systematically underreport AEs in hospitalized children with limited English proficiency.

Association of Early Physician Follow-up With Readmission Among Patients Hospitalized for Acute Myocardial Infarction, Congestive Heart Failure, or Chronic Obstructive Pulmonary Disease.
Investigators assessed whether hospitalized patients with early physician follow-up after discharge had lower rates of overall and condition-specific readmissions within 30 days and 90 days of discharge. Studying adults in Ontario, Canada, with first admission for acute myocardial infarction, congestive heart failure, or chronic obstructive pulmonary disease, the findings suggested that early follow-up in conjunction with a comprehensive transitional care strategy for hospitalized patients with medically complex conditions coupled with ongoing effective chronic disease management may be associated with reduced 90-day readmissions.

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.

Comorbidities associated with hospitalization and progression among adolescents with symptomatic coronavirus disease 2019.
This study’s objective was to identify subgroups likely to benefit from monoclonal antibody and antiviral therapy to treat COVID-19 by evaluating the relationship between comorbidities and hospitalization among US adolescents aged 12-17 with symptomatic coronavirus disease 2019 (COVID-19). The authors used the Pediatric COVID-19 US registry to identify patients who met their inclusion criteria of comorbidities including obesity, chronic kidney disease (CKD), diabetes, immunosuppressive disease or treatment, sickle cell disease (SCD), heart disease, neurologic disease/neurodevelopmental disorders, and pulmonary disease (excluding patients with mild asthma). Out of 1877 total patients included 284 (15%) were hospitalized within 28 days of their COVID-19 diagnosis. The following comorbidities were associated with increased odds of hospitalization: SCD, immunocompromising condition, obesity, diabetes, neurologic disease, and pulmonary disease (excluding mild asthma).

Development of a novel emergency department quality measure to reduce very low-risk syncope hospitalizations.
The purpose of this study was to develop a new quality measure to apply with very low risk adult emergency department patients under 50 years of age and with no history of heart disease presenting with syncope. The study found that of the 3,292 patients meeting the study criteria, .46% suffered serious adverse events within 30 days after discharge. When the criteria were applied to the 2019 Nationwide Emergency Department Sample (NEDS) to assess its potential effect (assessing for hospital-level factors associated with hospitalization variation), of the 566,031 patients meeting the criteria, 2.7% were hospitalized. The researchers identified factors associated with increased hospitalization rates, which included a yearly ED volume of more than 80,000 and metropolitan teaching status. The study concluded that the novel syncope quality measure developed by the researchers can evaluate variation in low-value hospitalizations for unexplained syncope.

Organization of outpatient care after COVID-19 hospitalization.
The purpose of this study was to describe post-discharge care delivery for patients with postacute sequelae of COVID-19 (PASC) across a large network of US academic and community hospitals. Beginning in July, 2021, the researchers surveyed 47 hospitals which were participating in the National Heart, Lung, and Blood Institute Clinical Trials Network for the Prevention and Early Treatment of Acute Lung Injury (PETAL Network.) Surveys were completed by physicians, hospital administrators, social workers, research staff or other clinicians over an 8-week period, and data from the 2019 American Hospital Association annual survey database were used to describe the hospitals. The study found that 79% (37) of the responding hospitals provided COVID-specific discharge information to patients hospitalized with COVID-19. Only 26% of hospitals provided discharge information that included potential symptoms or impairments of postacute sequelae of COVID-19. Seventy percent (33) had a PASC clinic (a postdischarge outpatient clinic designed specifically for patients with COVID). Hospitals without PASC clinics were more likely to be located in a ZIP code with a higher Medicare population and a median annual income lower than $40,000, and were also more likely to be smaller, for-profit hospitals. The researchers identified several core areas for possible improvements in PASC care, including: examining the impact of PASC clinics on patient outcomes; assessing the extent to which the pathophysiology and management of PASC differ from sequelae of other infections and syndromes; and exploring whether an inability to systematically identify patients for PASC care may result in an inability for some patients to receive needed care. The researchers concluded that PASC clinics may offer opportunities to coordinate care and serve as an opportunity for making iterative gains in knowledge about PASC clinics and related models and processes and their effectiveness in improving longer-term patient-centered outcomes for survivors of COVID-19.

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.

Documentation of hospitalization risk factors in electronic health records (EHRs): a qualitative study with home healthcare clinicians.
The objectives of this study were to identify risk factors that home healthcare clinicians associate with patient deterioration and to understand clinicians’ response to and documentation of these risk factors. The authors interviewed multidisciplinary home healthcare clinicians and used directed content analysis to identify risk factors for deterioration. A total of 79 risk factors were identified by the clinicians, who responded most often by communicating with the prescribing provider or following up with patients and caregivers. Clinicians also acknowledged that social factors played a role in deterioration risk. The authors noted that, since most risk factors were documented in clinical notes, methods such as natural language processing are needed to extract them. They concluded that by providing a comprehensive list of risk factors grounded in clinician expertise and mapped to standardized terminologies, the results of their study supported the development of an early warning system for patient deterioration.

Depressive symptoms and incident hospitalization for heart failure: findings From the REGARDS Study.
The purpose of this study was to determine whether depressive symptoms are associated with incident heart failure (HF), including hospitalization for HF overall or by subtype: HF with preserved (HFpEF) or reduced ejection fraction (HFrEF). The study found that over a median of 9.2 years of follow-up, there were 872 incident HF hospitalizations, 526 among those without CHD and 334 among those with CHD. The age-adjusted HF hospitalization incidence rates per 1000 person-years were 4.9 for participants with depressive symptoms compared with 3.2 for participants without depressive symptoms. For overall HF, the elevated risk lessened after controlling for covariates. Among those without baseline CHD, when HFpEF was evaluated separately, after controlling for all covariates, depressive symptoms were related with incident hospitalization. In contrast, depressive symptoms were not related with incident HFrEF hospitalizations. The researchers concluded that among individuals without CHD at baseline, depressive symptoms were related with incident hospitalization for HFpEF, but not for those with baseline CHD or HFrEF.

Child Opportunity Index 2.0 and acute care utilization among children with medical complexity.
This cross-sectional, multicenter study examined the association between ZIP code-level opportunity and acute care utilization among children with medical complexity (CMS). The authors assessed associations between the nationally-normed, multi-dimensional ZIP code-level Child Opportunity Index 2.0 (COI) and total utilization days (hospital bed-days + emergency department (ED) discharge encounters). In adjusted analyses, patients in the lowest COI quintile (lowest opportunity) utilized care at 1.22 times the rate of those from the highest COI quintile.

Interaction of microbiome, diet, and hospitalizations between Brazilian and American patients with cirrhosis.
This study’s objective was to compare cirrhosis patients from the United States with cirrhosis patients from Brazil with respect to diet, microbiota, and impact on hospitalizations. This case-control study had participants undergo dietary recall and provide stool samples for 16S ribosomal RNA sequencing. Demographics and medications/cirrhosis details were also compared. Cirrhosis patients were followed up for 90-day hospitalizations. More Americans were men, had higher hepatic encephalopathy and alcohol/hepatitis C etiology with lower nonalcoholic fatty liver disease than Brazilians. Model for end-stage liver disease (MELD), diabetes, ascites, and albumin were similar. Within participants with cirrhosis, microbial diversity was higher for Brazilians, and among Brazilians high diversity was related to Brazilian origin, age, and cereal intake. High MELD scores and ascites was related to lower diversity. Beneficial taxa and taxa associated with yogurt intake was higher was pathobionts were lower in Brazilians. More Americans were hospitalized than Brazilians.

Neighborhood socioeconomic deprivation and health care utilization of medically complex children.
The authors sought to assess the association between neighborhood socioeconomic deprivation and health care utilization in a cohort of children with medical complexity. They found no association between area-level deprivation and emergency department visits, hospitalizations, or inpatient bed-days. However, there was a 13% relative increase in the missed clinic visit rate for every 0.1 unit increase in Deprivation Index. They concluded that a child's socioeconomic context is associated with adherence to patient-centered medical home visits.

Assessing proximate intermediates between ambient temperature, hospital admissions, and mortality in hemodialysis patients.
This study investigated whether pre-dialysis systolic blood pressure (preSBP) and interdialytic weight gain (IDWG) in individuals with end-stage kidney disease (ESKD) can independently mediate the association between ambient temperature, all-cause hospital admissions (ACHA), and all-cause mortality (ACM). The study population consisted of 1981 ESKD patients receiving hemodialysis treatments at Fresenius Medical Care facilities in Philadelphia County, PA, from 2011 to 2019. Within a time-to-event framework, the authors estimated the association between daily maximum dry-bulb temperature (TMAX) and, as separate models, ACHA and ACM during warmer calendar months. Based on Lag 2- Lag 1 temporal ordering, and a 1 °C increase in daily maximum dry-bulb temperature (TMAX), the authors found an increased hazard of ACHA by 1.4% and ACM 7.5%. Short-term lag exposures to 1 °C increase in temperature predicted mean reductions in IDWG and preSBP by 0.013-0.015% and 0.168-0.229 mmHg.

Early identification of patients admitted to hospital for covid-19 at risk of clinical deterioration: model development and multisite external validation study.
The authors sought to create and validate a simple and transferable machine learning model from electronic health record data to accurately predict clinical deterioration in patients with COVID-19 across institutions, through use of a novel paradigm for model development and code sharing. They determined that a model to predict clinical deterioration was developed rapidly in response to the COVID-19 pandemic at a single hospital, was applied externally without the sharing of data, and performed well across multiple medical centers, patient subgroups, and time periods, showing its potential as a tool for use in optimizing healthcare resources.

Leveraging survey and claims data to identify high-need Medicare beneficiaries in the National Health and Aging Trends Study.
The purpose of this retrospective cohort study was to compare the performance of existing survey and claims-based definitions in identifying high-need (HN) Medicare population beneficiaries and predicting poor outcomes among a community-dwelling population. The researchers utilized Round 5 (2015) of the National Health and Aging Trends Study (NHATS) linked with Medicare claims and applied HN definitions from prior studies to the current study cohort. The study found that the percentage of NHATS respondents categorized as HN differed greatly across definitions. HN respondents had significantly higher mortality and hospitalization rates in 2016. The researchers report that although all the definitions utilized had good specificity, none were sufficiently accurate in their ability to predict outcomes in the following year.

Primary care visits and ambulatory care sensitive diabetes hospitalizations among adult Alabama Medicaid beneficiaries.
This retrospective cohort study described patterns of care use for Alabama Medicaid adult beneficiaries with diabetes and the association of primary care utilization and ambulatory care sensitive (ACS) diabetes hospitalizations. Alabama Medicaid claims data from January 2010 to April 2018 for 52, 549 covered adults aged 19-64 with diabetes was analyzed. Individuals were categorized by demographics, comorbidities, and health care use. Characteristics of the cohort with and without ACS hospitalization was reported. One third of the cohort had at least one ACS diabetes hospitalization over the observed periods. Hospital users tended to have multiple ACS hospitalizations as well as more comorbidities and pharmaceutical and other types of care use than those with no ACS hospitalizations. Having a primary care visit in one year was significantly associated with a reduced likelihood of ACS hospitalization in the following year.

The purpose of this study was to examine the impact of adherence to continuous positive airway pressure (CPAP) therapy on health care utilization among a nationally representative and sample of older adults with multiple morbidities and pre-existing cardiovascular disease and subsequently diagnosed with obstructive sleep apnea in the United States. The investigators concluded that in this nationally representative sample of older Medicare beneficiaries with multiple morbidities and relative to low adherers, high adherers demonstrated reduced inpatient utilization.

Cause-specific risk of hospital admission related to extreme heat in older adults.
The purpose of this study was to identify possible causes of hospital admissions during extreme heat events and to estimate their risks using historical data. The investigators found that among older adults, periods of extreme heat were associated with increased risk of hospitalization for fluid and electrolyte disorders, renal failure, urinary tract infection, septicemia, and heat stroke. They noted however, that the absolute risk increase was small and of uncertain clinical importance.

Comparative effectiveness of laparoscopic adjustable gastric banding vs laparoscopic gastric bypass.
A retrospective study of 7,457 patients undergoing laparoscopic bariatric surgery found that patients receiving gastric bypass experienced much greater weight loss than those receiving gastric banding but they had a higher risk of short-term complications and long-term subsequent hospitalizations. However, gastric bypass patients had a lower risk of long-term subsequent intervention procedures than did gastric banding patients.

Disparities in diabetes-related preventable hospitalizations among working-age Native Hawaiians and Asians in Hawai'i.
Elderly (65+) Native Hawaiian, Filipino, and Japanese men and Filipino women have a higher risk of diabetes-related potentially preventable hospitalizations than whites. The authors sought to determine if similar disparities are seen among the non-elderly (< 65). They found that preventable hospitalizations rates were significantly higher for Native Hawaiians males compared to whites, but significantly lower for Chinese men and women, Japanese men and women, and Filipino men and women. Rates for Native Hawaiian females did not differ significantly from Whites. Disparities in diabetes-related preventable hospitalizations were seen for working-age (18-64) Native Hawaiian men even when their higher population-level diabetes prevalence was considered.

Emergency department visits for heart failure and subsequent hospitalization or observation unit admission.
The purpose of this study was to examine trends in ED visits for heart failure and disposition following such visits. The investigators found that the number of ED visits for heart failure and the high proportion of ED visits with subsequent inpatient hospitalization have not changed in the last decade. They suggest that opportunities may exist to reduce hospitalizations by increasing short-term management of heart failure in the ED or observation unit.

Pediatric inpatient hospital resource use for congenital heart defects.
The authors sought to estimate healthcare costs for infants, children, and adolescents with congenital heart defects (CHDs). Using the 2009 Healthcare Cost and Utilization Project Kids' Inpatient Database (KID), they found that hospitalizations for children with CHDs have disproportionately high hospital costs compared with other pediatric hospitalizations, and the 17% of hospitalizations with critical CHD diagnoses accounted for 27% of CHD hospital costs.
