Evaluation of federated learning variations for COVID-19 diagnosis using chest radiographs from 42 US and European hospitals.
The goals of this study were to compare a single-site, COVID-19 computer diagnosis system that used the Federated Averaging (FedAvg) algorithm with 3-client Federated learning (FL) models, and to evaluate the performance of the four FL variations. Researchers leveraged a FL healthcare collaborative that included data from five US and European healthcare systems encompassing 42 hospitals. They concluded that FedAvg could significantly improve generalization of the model in comparison with other personalization FL algorithms--FedProx, FedBN, and FedAMP--but at the cost of poor internal validity.

Performance of physician groups and hospitals participating in bundled payments among Medicare beneficiaries.
This cohort study compared how physician group practices (PGPs) performed in bundled payments compared with hospitals. The authors used 2011 to 2018 Medicare claims data to compare the association of participants in the Bundled Payments for Care Improvement (BCPI) initiative with episode outcomes. Primary outcome was 90-day total episode spending. The total sampled comprised data from 1,288,781 Medicare beneficiaries, of whom mean age was 76.2 years, 59.7% women, and 85.5% White, with 592,071 individuals receiving care from 6405 physicians in in BPCI-participating PGPs and 24,758 propensity-matched physicians in non-BPCI-participating PGPs. For PGPs, BPCI participation was associated with greater reductions in episode spending for surgical (difference, -$1648 to -$1088) but not for medical episodes (difference, -$410 to $206). Hospital participation in BPCI was associated with greater reductions in episode spending for both surgical ($1345 to -$675) and medical -$1139 to -$386) episodes.

Hospitals that report severe sepsis and septic shock bundle compliance have more structured sepsis performance improvement.
This study linked survey data on quality improvement (QI) practices from Iowa hospitals to severe sepsis/septic shock (SEP-1) performance data and mortality. All Iowa hospitals (100%) completed the survey. SEP-1 reporting hospitals were more likely to have sepsis QI practices, including reporting sepsis quality to providers (64% versus 38%) and using the case review process to develop sepsis care plans. Increased SEP-1 scores were not associated with sepsis QI practices. A sepsis registry was associated with decreased odds of being in the bottom quartile of sepsis mortality, and presence of a sepsis committee was associated with lower hospital-specific mortality.

Is the recent surge in physician-hospital consolidation finally producing cost-savings?
This article revisits earlier integration studies using IBM MarketScan data 2010–2016 to re-examine the relationship between primary care physicians integrated with hospitals and spending under the Affordable Care Act (ACA) during that period. The authors observe an association between physician-hospital integration and overall cost-savings, a reversal of the relationship noted in earlier studies. They recommend that future research examine the precise mechanism of physician-hospital clinical integration in greater detail.

The association of strained ICU capacity with hospital patient racial and ethnic composition and federal relief during the COVID-19 pandemic.
Investigators sought to identify the association between strained intensive care unit (ICU) capacity during the COVID-19 pandemic and hospital racial and ethnic patient composition, federal pandemic relief, and other hospital characteristics. They found that hospitals with large Black patient shares experienced greater strain during the pandemic. These hospitals received more federal relief; however, funding was not targeted overall toward hospitals with high ICU occupancy rates.

Understanding hazards for adverse drug events among older adults after hospital discharge: insights from frontline care professionals.
The purpose of this study was to utilize a systems approach to examine hazards to medication safety for older adults during care transitions. The researchers interviewed 38 hospital-based professionals (5 hospitalists, 24 nurses, 4 clinical pharmacists, 3 pharmacy technicians, and 2 social workers) from 4 hospitals about ADE risks after hospital discharge among older adults. For each concern the participants provided, the hazard for medication-related harms was coded and grouped by its sources utilizing a human factors and systems engineering model. The study found that the hazards fell into 6 groups: 1) medication tasks related at home, 2) patient and caregiver related, 3) hospital work system related, 4) home resource related, 5) hospital professional-patient collaborative work related, and 6) external environment related. The type of medications indicated most frequently when describing concerns included anticoagulants, insulins, and diuretics. The types of hazards coded the most were: complex dosing, patient and caregiver knowledge gaps in medication management, errors in discharge medications, unaffordable cost, inadequate understanding about changes in medications, and gaps in access to care or in sharing medication information.

Interhospital variability in health care-associated infections and payments after durable ventricular assist device implant among Medicare beneficiaries.
The purpose of this study was to examine differences in durable ventricular assist device implantation infection rates and associated costs across hospitals. The researchers utilized clinical data for 8,688 patients who received primary durable ventricular assist devices from the Society of Thoracic Surgeons Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs) hospitals (n = 120) and merged that data with post-implantation 90-day Medicare claims. The primary outcome included infections within 90 days of implantation and Medicare payments. The study found that 27.8% of patients developed 3982 identified infections. The median adjusted incidence of infections (per 100 patient-months) across hospitals was 14.3 and differed according to hospital. Total Medicare payments from implantation to 90 days were 9.0% more in high versus low infection tercile hospitals. The researchers concluded that health-care-associated infection rates post durable ventricular assist device implantation varied according to hospital and were associated with increased 90-day Medicare expenditures.

Association between in-person vs telehealth follow-up and rates of repeated hospital visits among patients seen in the emergency department.
This study investigated whether the rates of emergency department (ED) return visits and hospitalization differ between patients who obtain in-person versus telehealth encounters for post-ED follow-up care. This retrospective cohort study included adult patients who came to either of 2 in-system EDs of a single urban integrated academic system from April 2020 to September 2021, were discharged home, and obtained a follow-up appointment with a primary care physician within 14 days of their index ED visit. Overall, the study recorded 12,848 patients with 16,987 ED encounters (mean age 53 years; 57% women, 12% Black or African American; 22% Hispanic or Latinx; and 58% White) included. Overall, 17% of initial ED encounters led to returns to the ED, and 4% subsequent hospitalizations. Telehealth vs in-person follow-up visits were associated with increased rates of ED returns (28.3 more ED returns per 1000 encounters) and hospitalizations (10.6 more hospitalizations per 1000 encounters).

Hospital volume predicts guideline-concordant care in stage III esophageal cancer.
This study developed quality measures for management of stage III esophageal cancer including: utilization of neoadjuvant therapy, surgical sampling of at least 15 lymph nodes, resection within 60 days of chemotherapy or radiation, and completeness of resection to determine whether hospital volume varies measure adherence of published guidelines. A total of 1345 hospitals participating in the National Cancer Database from 2004 to 2016 were included. The authors examined association of volume, program accreditation, safety net status, geographic region, and patient travel distance on adequate adherence (≥85% of patients are adherent) using logistic regression modeling. The rate of adequate adherence was worst in nodal staging at 12.6% and highest for utilization of neoadjuvant therapy at 84.8%. Academic programs had the highest rate of adequate adherence for induction therapy (77.2%), timing of surgery (56.6%), and completeness of resection (78.5%) but lowest for nodal staging at only 4.4%. Every additional esophagectomy performed per year increased the odds of adequate adherence for induction therapy and completeness of resection but decreased for nodal staging.

Improving quality and safety for patients after hospital discharge: primary care as the lead integrator in postdischarge care transitions.
The purpose of this study was to explain primary care-based transition workflow processes for hospitalized patients. The researchers conducted interviews with primary care thought leaders, staff at 9 primary care sites, community agency staff, and recently discharged patients. The researchers found that primary care postdischarge workflows vary across the different settings, rarely include communications with the patient or the inpatient team during the hospitalization and vary widely across settings. The researchers recommended the use of principles for primary care practices to encourage active participation in the full spectrum of postdischarge care, from admission through the first postdischarge visit to primary care.

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.

Rural Medicare beneficiaries are increasingly likely to be admitted to urban hospitals.
This study looked at trends in admission to urban hospitals by rural Medicare FFS beneficiaries from 2010 to 2018. The authors combined data from the 2010 to 2018 Hospital Service Area File (HSAF) and the 2010-2017 American Hospital Association (AHA) survey. They found that controlling for distance to the nearest hospitals, an increase of 1 year was associated with a 2.0% increase in the number of admissions to urban hospitals from each rural ZIP code. New system affiliation of the nearest rural hospital was associated with an increase of 1.7%.

Which hospital-acquired conditions matter the most in trauma? An evidence-based approach for prioritizing trauma program improvement.
The purpose of this study was to quantify and compare the impacts of six different hospital-acquired conditions (HACs) on early clinical outcomes and resource utilization in hospitalized trauma patients. The researchers included 529,856 adult patients from the 2013 to 2016 American College of Surgeons Trauma Quality Improvement Program Participant Use Data Files with 5 days or longer of hospitalization and had an Injury Severity Score of 9 or higher. The study found the incidences of HACs were: pneumonia, 5.2%; urinary tract infection, 3.4%; venous thromboembolism, 3.3%; surgical site infection, 1.3%; pressure ulcer, 1.3%; and central line-associated blood stream infection, 0.2%. The HAC of pneumonia demonstrated the largest association with in-hospital outcomes and resource utilization. The researchers reported that prevention of pneumonia within the study group would have resulted in estimated reductions of: 22.1% for end organ dysfunction, 8.7% for prolonged hospitalization, 7.8% for mortality, 7.1% for prolonged intensive care unit stay, and 6.8% for need for mechanical ventilation. The researchers concluded that pneumonia prevention should be a priority activity in program improvement efforts.

Association of insurance mix and diagnostic coding practices in New York state hospitals.
This study’s goal was to estimate whether, for the same Medicaid enrollee with multiple hospitalizations, a hospital's share of privately insured patients is associated with the number of diagnoses on claims since privately insured hospitals may invest more in intensive coding than hospitals serving publicly insured patients. This cross-sectional study used patient-level fixed effects regression models on inpatient Medicaid claims from Medicaid enrollees with at least 2 admissions in at least 2 different hospitals in the state of New York between 2010 and 2017. This analysis included 1,614,630 hospitalizations for Medicaid-insured patients (mean age, 48.2 years; 51.4% women and 48.6% men). Overall, 74,998 were Asian, 462,259 Black, 375,591 Hispanic, 486,313 White, 128,896 unknown, and 86,573 other. When the same patient was seen in a hospital with a higher share of privately insured patients, more diagnoses were recorded. Patients discharged from hospitals in the bottom quartile of privately insured patient share received 1.37 more diagnoses when they were subsequently discharged from hospitals in the top quartile, relative to patients whose admissions were both in the bottom quartile. This suggests that payment policy may drive differential investments in infrastructure to document diagnosis, causing a feedback loop that exacerbates resource inequity.

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.

Current use, training, and barriers in point-of-care ultrasound in hospital medicine: a national survey of VA hospitals.
This study aimed to characterize current point-of-care ultrasound (POCUS) use, training needs, and barriers to use among hospital medicine groups (HMGs). This prospective observation study looked at all Veterans Affairs (VA) medical centers from August 2019 to March 2020 using a web-based survey sent to all chiefs of HMGs. There was a 90% response rate from 117 HMGs. Procedural POCUS use decreased by 19% from 2015 to 2020 but increased for diagnostic use for cardiac (8%), pulmonary (7%), and abdominal (8%) applications. The most common barrier to POCUS use was lack of training (89%), with only 34% of HMGs having access to POCUS training. Access to ultrasound equipment was the least common barrier at 57%, however with the proportion of HMGs with ≥1 ultrasound machine increasing from 29% to 71% from 2015 to 2020. In 2020 an average of 3.6 ultrasound devices per HMG was available, and 45% were handheld devices.

Temporal trends in antimicrobial prescribing during hospitalization for potential infection and sepsis.
This study examined whether the push to administer antimicrobials to prevent sepsis has increased antimicrobial use in general. This observational cohort study of hospitalized patients at 152 hospitals in 2 health care systems during 2013 to 2018 looked at almost 1.6 million patients (81% male), admitted via the emergency department with 2 or more systemic inflammatory response syndrome (SIRS) criteria. From 2013 to 2018 first antimicrobial administration to patients with sepsis decreased by 37 minutes. At the same time, antimicrobial use within 48 hours, days of antimicrobial therapy, and receipt of broad-spectrum coverage decreased among the broader cohort of patients with systemic inflammatory response syndrome (SIRS). This may have caused a decrease in in-hospital mortality, 30-day mortality, length of hospitalization, new MDR culture positivity, and new MDR blood culture positivity over the study period among both patients with sepsis and those with SIRS. For the overall hospital population there was no evidence that increasing antimicrobial timing for sepsis was associated with increasing antimicrobial use or impaired antimicrobial stewardship.

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.

Trends in adverse event rates in hospitalized patients, 2010-2019.
This AHRQ-authored serial cross-sectional study’s objective was to determine the change in the rate of adverse events in hospitalized patients from 2010 to 2019. The study used data from the Medicare Patient Safety Monitoring System and included 244,542 adult patients hospitalized in 3156 acute care hospitals across 4 condition groups: acute myocardial infarction (17%), heart failure (17%) pneumonia (21%), major surgical procedures (22%), and all other conditions (22%). Information on adverse events collected included 21 measures across 4 adverse event domains: adverse drug events, hospital-acquired infections, adverse events after a procedure, and general adverse events such as pressure ulcers and falls. The study sample included 190,286 hospital discharges in the combined 4 condition-based groups and 54,256 hospital discharges for all other conditions. From 2010 to 2019, the total change for adverse events per 1000 discharges for acute myocardial infarction decreased from 218 to 139, from 168 to 116 for heart failure, from 195 to 119 for pneumonia, and from 204 to 130 for major surgical procedures. The rate for all other conditions remained unchanged at 70 adverse events per 1000 discharges.

Causes of death in the 12 months after hospital discharge among patients with opioid use disorder.
This study described causes of death in the year post-discharge among hospitalized patients with Opioid Use Disorder (OUD). Data was analyzed from participants at least 18 years old with Medicaid insurance, who had a diagnosis of OUD during a general hospital admission in Oregon. Findings showed that hospitalized patients with OUD were at high risk of death, from drug and non-drug related causes, in the year after discharge. Recommendations included future research considering not only overdose, but a more comprehensive definition of drug-related death in understanding post-discharge mortality among hospitalized patients with OUD.

Hospital-physician integration and risk-coding intensity.
This study analyzed whether hospital-physician integration affects providers' coding of patient severity, because greater diagnostic severity will increase practices’ payment under risk-based arrangements. The authors used a two-way fixed effects model, an event study, and a stacked difference-in-differences analysis of 5 million patient-year observations from 2010 to 2015. They found that the integration of a patient's primary care doctor is associated with a robust 2%-4% increase in coded severity, the risk-score equivalent of aging a physician's patients by 4-8 months. This effect wasn’t driven by physicians treating different patients nor by physicians seeing patients more often. Their evidence is consistent with the hypothesis that hospitals share organizational resources with acquired physician practices to increase the measured clinical severity of patients. They believe that increases in the intensity of coding will improve vertically-integrated practices' performance in alternative payment models and pay-for-performance programs while raising overall health care spending.

Risk of closure among independent and multihospital-affiliated rural hospitals.
The purpose of this study was to examine the association between affiliation and rural hospital closure. Using HCUP data, findings showed that, among financially distressed hospitals, affiliation was associated with lower risk of closure compared with being independent; conversely, among hospitals that were financially stable, affiliation was associated with higher risk of closure compared with being independent. Further, for-profit ownership was strongly associated with closure for hospitals that were financially stable.

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.

Variation in condition-specific readmission rates across US children's hospitals.
This retrospective cohort study examined variation in condition-specific readmission rates across US children’s hospitals. The authors looked at 49 US children’s hospitals in the Pediatric Health Information System in 2017. They ranked the highest volume conditions by rate variation (RV, interquartile range divided by the median) for each condition across hospitals. The sample included 811,434 index hospitalizations with 6.2% 30-day readmissions. The RV across hospitals/conditions was between 0 and 2.8 with a median of 0.7. Common reasons for admission had low RVs across hospitals, including bronchiolitis, seizure, and asthma. They identified 33 conditions with high variation in readmission rates across hospitals, which accounted for 18% of all discharges and 11% of all pediatric readmissions.

Adherence to a federal hospital price transparency rule and associated financial and marketplace factors.
This research letter describes a study that evaluated adherence to the federal Hospital Price Transparency Rule 6 to 9 months after the final rule effective date (January 1, 2021). The rule’s aim is to increase health price transparency and facilitation patient price shopping online. Hospitals were required to post 5 price types: gross charges, discounted prices, payer-specific negotiated prices, minimum and maximum prices in a machine-readable file, and a separate accessible display or price estimator for at least 300 shoppable items. The authors used the Herfindahl-Hirschman Index (HHI) to measure inpatient hospital market concentration. The data was collected for 185 of 929 core-based statistical areas from 2019. HHI is divided into the following categories: unconcentrated, moderately concentrated, or highly or very concentrated. Results showed that out of 5239 total hospitals, 729 (13.9%) had an adherent machine-readable file but no shoppable display, 1542 (29.4%) had an adherent shoppable display but no machine-readable file, and 300 (5.7%) had both. The most adherent hospitals tended to be acute care hospitals with lesser revenue per patient-day, within unconcentrated health care markets, and in urban areas.
