Genomics of Aminoglycoside Resistance in Pseudomonas aeruginosa Bloodstream Infections at a United States Academic Hospital.

Pseudomonas aeruginosa frequently becomes resistant to aminoglycosides by the acquisition of aminoglycoside modifying enzyme (AME) genes and the occurrence of mutations in the mexZ, fusA1, parRS, and armZ genes. We examined resistance to aminoglycosides in a collection of 227 P. aeruginosa bloodstream isolates collected over 2 decades from a single United States academic medical institution. Resistance rates of tobramycin and amikacin were relatively stable over this time, while the resistance rates of gentamicin were somewhat more variable. For comparison, we examined resistance rates to piperacillin-tazobactam, cefepime, meropenem, ciprofloxacin, and colistin. Resistance rates to the first four antibiotics were also stable, although uniformly higher for ciprofloxacin. Colistin resistance rates were initially quite low, rose substantially, and then began to decrease at the end of the study. Clinically relevant AME genes were identified in 14% of isolates, and mutations predicted to cause resistance were relatively common in the mexZ and armZ genes. In a regression analysis, resistance to gentamicin was associated with the presence of at least one gentamicin-active AME gene and significant mutations in mexZ, parS, and fusA1. Resistance to tobramycin was associated with the presence of at least one tobramycin-active AME gene. An extensively drug-resistant strain, PS1871, was examined further and found to contain five AME genes, most of which were within clusters of antibiotic resistance genes embedded in transposable elements. These findings demonstrate the relative contributions of aminoglycoside resistance determinants to P. aeruginosa susceptibilities at a United States medical center. IMPORTANCE Pseudomonas aeruginosa is frequently resistant to multiple antibiotics, including aminoglycosides. The rates of resistance to aminoglycosides in bloodstream isolates collected over 2 decades at a United States hospital remained constant, suggesting that antibiotic stewardship programs may be effective in countering an increase in resistance. Mutations in the mexZ, fusA1, parR, pasS, and armZ genes were more common than acquisition of genes encoding aminoglycoside modifying enzymes. The whole-genome sequence of an extensively drug resistant isolate indicates that resistance mechanisms can accumulate in a single strain. Together, these results suggest that aminoglycoside resistance in P. aeruginosa remains problematic and confirm known resistance mechanisms that can be targeted for the development of novel therapeutics.

Local food procurement by hospitals: a scoping review.

Local food procurement by hospitals is gaining traction as governments and advocacy groups seek to influence food systems and strengthen local communities, but there is little empirical evidence as to its practical application or efficacy. The aims of this review were to describe the extent, range and nature of local food procurement models in healthcare foodservices, and to understand the barriers and enablers to implementation, including from the perspective of stakeholders across the supply chain. A scoping review was conducted following the protocol published in the Open Science Framework Registration (DOI: 10.17605/OSF.IO/T3AX2). Five electronic databases were searched for the following concepts: 'hospital foodservice', 'local food procurement practices', 'the extent, range and nature' and/or 'the barriers and enablers of procurement'. Eligible peer-reviewed original research published in English from the year 2000 was included following a two-step selection process. The final library included nine studies. Most studies (7 of 9) were from the United States. Three studies used survey methods and reported high rates (58%-91%) of US hospital participation in local food procurement. Studies offered minimal description of local procurement models, but two models, conventional ('on-contract') or off-contract, were typically used. Barriers to local food procurement included restricted access to suitable local food supply, limited kitchen resources and inadequate technology to trace local food purchase thereby limiting evaluation capabilities. Enablers included organisational support, passionate champions and opportunistic, incremental change. There is a paucity of peer-reviewed studies describing local food procurement by hospitals. Details of local food procurement models were generally lacking: categorisable as either purchases made 'on-contract' via conventional means or 'off-contract'. If hospital foodservices are to increase their local food procurement, they require access to a suitable, reliable and traceable supply, that acknowledges their complexity and budgetary constraints.

Parental Leave Policies in the Top 20 US Hospitals: A Call for Inclusivity and Improvement.

To evaluate and compare parental leave policies from the top United States (US) hospitals with a focus on inclusivity of all types of parents. In September and October of 2021, the parental leave policies of the top 20 US hospitals, ranked by the 2021 US News & World report, were evaluated. Parental leave policies were obtained and reviewed through the hospitals' public websites. Hospitals' Human Relations (HR) departments were contacted to confirm the policies. Hospital policies were scored against a rubric created by the authors. Among the top US hospitals (21 total hospitals), 17 (81%) had publicly available policies, and one policy was obtained by contacting HR. Fourteen of the 18 hospitals (77.8%) had a parental leave policy distinctive from short-term disability and offered paid paternity or partner leave. Thirteen hospitals (72.2%) offered parental leave for parents whose children were carried through surrogacy. Fourteen hospitals (77.8%) included adoptive parents; however, only five hospitals (27.8%) specifically included foster parents. The average paid leave for birthing mothers was 7.9 weeks compared to 6.6 weeks for nonbirthing parents. Only three hospitals offered the same leave for birthing and nonbirthing parents. While a few of the top 20 hospitals have paid parental leave policies that are inclusive and equivalent to all parents, many do not and represent an area for improvement. As healthcare industry leaders, these hospitals should strive for inclusive parental leave policies that care for their employees with the same high standards they set for caring for patients.

Dermatologic toxicities of anti-neoplastic immunotherapy in United States hospitalizations.

A major side effect of anti-neoplastic immunotherapy is the onset of dermatologic toxicities following the administration of several different immunotherapy drugs. We sought to assess the incidence and mortality of anti-neoplastic immunotherapy-associated dermatologic toxicities using a nationally representative sample of United States (US) adults. The National Inpatient Sample database was queried for encounters undergoing anti-neoplastic immunotherapy. Multiple logistic regression models were constructed to analyze incidence of dermatologic toxicity and associated mortality as well as calculate adjusted odds ratios (aOR) after controlling for age, race, sex, household income, and cancer type. Immunotherapy patients demonstrated greater odds of developing pruritus (aOR = 7.59; 95% CI 5.17-11.2; P < 0.001), rash (aOR = 2.81; 95% CI 2.00-3.94, P < 0.001), generalized (aOR = 5.32; 95% CI 3.35-8.43; P < 0.001) and localized (aOR = 2.67; 95% CI 1.01-7.05; P < 0.001) skin eruptions, and vitiligo (aOR = 13.3; 95% CI 5.15-34.4; P < 0.001) compared to patients who did not receive anti-neoplastic immunotherapy. There were no significant differences observed in incidence of non-scarring alopecia (P = 0.7), psoriasis (P = 0.094), and dermatitis (P = 0.9) between the two groups. Patients who underwent immunotherapy were more likely to develop dermatologic toxicity (aOR = 3.93; 95% CI 3.12-4.94; P < 0.001), however, no significant differences in mortality were observed. Patients undergoing anti-neoplastic immunotherapy have an increased risk of developing dermatologic toxicity compared to patients who did not receive anti-neoplastic immunotherapy.

A Case Series of Non-Tuberculous Mycobacterial Pulmonary Disease Masquerading as Malignancy From a Community-Based Hospital

Non-tuberculous mycobacteria (NTM) are ubiquitous organisms in the environment that can potentially cause a range of pulmonary and extrapulmonary infections in humans. Epidemiological risk factors and the host’s immune status determine the susceptibility to various clinical syndromes caused by different NTM species. Non-tuberculous mycobacteria pulmonary disease (NTM-PD) is primarily reported in patients with underlying lung disease. These infections often pose a significant disease burden on affected patients as they are often chronic, difficult to treat, and necessitate long-term multi-drug therapy. Mycobacterium avium complex (MAC) is the most common causative pathogen of NTM-PD in the USA, followed by Mycobacterium kansasii ( M. kansasii ). Less common species in the USA include Mycobacterium xenopi ( M. xenopi ), Mycobacterium abscessus , and others, largely depending upon the geographic location and exposure to species-specific predisposing risks. In this case series, the authors report on three elderly patients with chronic lung diseases who had pulmonary NTM disease caused by M. xenopi and MAC. The patients were encountered in both inpatient and outpatient settings from a community-based hospital in the midwestern USA. The clinical and radiological features of NTM-PD masqueraded as malignancy and posed a diagnostic dilemma. The epidemiology, clinical and radiological features, diagnosis, and management of NTM-PD are reviewed in this report. J Med Cases. 2023;14(4):141-147 doi: https://doi.org/10.14740/jmc4098

Hospital factors that influence ICU admission decision-making: a qualitative study of eight hospitals.

Some hospitals in the United States (US) use intensive care 20 times more than others. Since intensive care is lifesaving for some but potentially harmful for others, there is a need to understand factors that influence how intensive care unit (ICU) admission decisions are made. A qualitative analysis of eight US hospitals was conducted with semi-structured, one-on-one interviews supplemented by site visits and clinical observations. A total of 87 participants (24 nurses, 52 physicians, and 11 other staff) were interviewed, and 40h were spent observing ICU operations across the eight hospitals. Four hospital-level factors were identified that influenced ICU admission decision-making. First, availability of intermediate care led to reallocation of patients who might otherwise be sent to an ICU. Second, participants stressed the importance of ICU nurse availability as a key modifier of ICU capacity. Patients cared for by experienced general care physicians and nurses were less likely to receive ICU care. Third, smaller or rural hospitals opted for longer emergency department patient-stays over ICU admission to expedite interhospital transfer of critically ill patients. Fourth, lack of clarity in ICU admission policies led clinicians to feel pressured to use ICU care for patients who might otherwise not have received it. Health care systems should evaluate their use of ICU care and establish institutional patterns that ensure ICU admission decisions are patient-centered but also account for resources and constraints particular to each hospital.

How to make PROMs work: qualitative insights from leaders at United States hospitals with successful PROMs programs.

Elucidate facilitators, barriers, and key lessons learned regarding the implementation of system-wide clinical patient-reported outcome measure (PROM) programs among United States (US) healthcare leaders. We conducted semi-structured interviews with 35 US healthcare leaders, including chief-level executives, data directors, PROM directors, and department chairs involved in PROM implementation across seven diverse healthcare systems from February to June 2020. Transcripts were coded, evaluated for qualitative themes, and categorized according to the consolidated framework for implementation research (CFIR). According to US hospital leaders with experience in existing clinical PROM programs, there are facilitators and barriers to implementation success in each CFIR domain. Allowing clinicians to select PROM measures and ensuring a user-friendly data platform (intervention); adapting data collection to patient home environments (outer setting); informing clinicians of the multi-faceted use of PROM data for research, clinical care, and business (inner setting); implementing PROM education earlier into clinician training (characteristics of individuals); and establishing specialty-agnostic PROM implementation teams (process) were among key facilitators to implementation success. Leaders of geographically and clinically diverse PROM programs in the US identify common themes that facilitate successful implementation. Drivers of success depend on factors within and outside the clinical environment. These findings may serve to guide both establishing new PROM programs and refining existing PROM programs.

Cultures of antibiotic prescribing in medical intensive care

Antimicrobial resistance (AMR) continues to present a challenge to international healthcare systems and structures of public health. The focus on optimizing antibiotic prescribing in human populations has challenged healthcare systems charged with making responsible their physician-prescribers. In the United States, physicians in almost every specialty and role use antibiotics as part of their therapeutic armamentariums. In United States hospitals, most patients are administered antibiotics during their stay. Therefore, antibiotic prescribing and utilization is a commonly accepted part of medical practice. In this paper, we utilize social science work on antibiotic prescribing to examine a critical space of care in United States hospital settings. From March to August 2018, we used ethnographic methods to study hospital-based medical intensive care unit physicians at the offices and hospital floors they frequent in two urban United States teaching hospitals. We focused on eliciting the interactions and discussions surrounding antibiotic decision-making that are uniquely influenced by the context of medical intensive care units. We argue that antibiotic use in the medical intensive care units under study was shaped by urgency, hierarchy, and uncertainty representative of the medical intensive care unit's role within the larger hospital system. We conclude that by studying the culture of antibiotic prescribing in medical intensive care units, we can see more clearly both the vulnerability of the looming antimicrobial resistance crisis and by contrast the perceived insignificance of stewarding antibiotic use when considered alongside the fragility of life amidst acute medical concerns regularly experienced in the unit.

Barriers and facilitators to interhospital transfer of acute pulmonary embolism: An inductive qualitative analysis.

Interhospital transfer (IHT) of patients with acute life-threatening pulmonary embolism (PE) is necessary to facilitate specialized care and access to advanced therapies. Our goal was to understand what barriers and facilitators may exist during this transfer process from the perspective of both receiving and referring physicians. This qualitative descriptive study explored physician experience taking care of patients with life threatening PE. Subject matter expert physicians across several different specialties from academic and community United States hospitals participated in qualitative semi-structured interviews. Interview transcripts were subsequently analyzed using inductive qualitative description approach. Four major themes were identified as barriers that impede IHT among patients with life threatening PE. Inefficient communication which mainly pertained to difficulty when multiple points of contact were required to complete a transfer. Subjectivity in the indication for transfer which highlighted the importance of physicians understanding how to use standardized risk stratification tools and to properly triage these patients. Delays in data acquisition were identified in regards to both obtaining clinical information and imaging in a timely fashion. Operation barriers which included difficulty finding available beds for transfer and poor weather conditions inhibiting transportation. In contrast, two main facilitators to transfer were identified: good communication and reliance on colleagues and dedicated team for transferring and treating PE patients. The most prominent themes identified as barriers to IHT for patients with acute life-threatening PE were: (1) inefficient communication, (2) subjectivity in the indication for transfer, (3) delays in data acquisition (imaging or clinical), and (4) operational barriers. Themes identified as facilitators that enable the transfer of patients were: (1) good communication and (2) a dedicated transfer team. The themes presented in our study are useful in identifying opportunities to optimize the IHT of patients with acute PE and improve patient care. These opportunities include instituting educational programs, streamlining the transfer process, and formulating a consensus statement to serve as a guideline regarding IHT of patients with acute PE.

The geography of Medicare's hospital value-based purchasing in relation to market demographics.

To illustrate the association between the sociodemographic characteristics of hospital markets and the geographic patterns of Medicare hospital value-based purchasing (HVBP) scores. This is a secondary analysis of United States hospitals with a HVBP Total Performance Score (TPS) for 2019 in the Centers for Medicare and Medicaid Services (CMS) Hospital Compare database (4/2021 release) and American Community Survey (ACS) data for 2015-2019. This is a cross-sectional study using spatial multivariable autoregressive models with HVBP TPS and component domain scores as dependent variables and hospital market demographics as the independent variables. We calculated hospital market demographics using ZIP code level data from the ACS, weighted the 2019 CMS inpatient Hospital Service Area file. Spatial autoregressive models using eight nearest neighbors with diversity index, race and ethnicity distribution, families in poverty, unemployment, and lack of health insurance among residents ages 19-64 years provided the best model fit. Diversity index had the highest statistically significant contribution to lower TPS (ß=-12.79, p < 0.0001), followed by the percent of the population coded to "non-Hispanic, some other race" (ß=-2.59, p < 0.0023), and the percent of families in poverty (ß=-0.26, p < 0.0001). Percent of the population was non-Hispanic American Indian/Alaskan Native (ß=0.35, p < 0.0001) and percent non-Hispanic Asian (ß=0.12, p < 0.02071) were associated with higher TPS. Lower predicted TPS was observed in large urban cities throughout the US as well as in states throughout the Southeastern US. Similar geographic patterns were observed for the predicted Patient Safety, Person and Community Engagement, and Efficiency and Cost Reduction domain scores but are not for predicted Clinical Outcomes scores. The lower predicted scores seen in cities and in the Southeastern region potentially reflect an inherent-that is, structural-association between market sociodemographics and HVBP scores.

Changing Epidemiology of Carbapenemases Among Carbapenem-Resistant Enterobacterales From United States Hospitals and the Activity of Aztreonam-Avibactam Against Contemporary Enterobacterales (2019-2021).

As the frequency of metallo-β-lactamase (MBL)-producing Enterobacterales is increasing worldwide, effective antimicrobials to treat the infections caused by these organisms are urgently needed. The activity of aztreonam-avibactam and comparators were evaluated against 27 834 Enterobacterales isolates collected from 74 US medical centers in 2019-2021. Isolates were susceptibility tested by broth microdilution. An aztreonam-avibactam pharmacokinetic/pharmacodynamic breakpoint of ≤8 mg/L was applied for comparison. Antimicrobial susceptibility and the frequency of key resistance phenotypes were assessed then stratified by year and infection type. Carbapenem-resistant Enterobacterales (CRE) were screened for carbapenemase (CPE) genes by whole genome sequencing. Aztreonam-avibactam inhibited >99.9% of Enterobacterales at ≤8 mg/L. Only 3 isolates (0.01%) had an aztreonam-avibactam minimum inhibitory concentration (MIC) >8 mg/L. The CRE rates were 0.8%, 0.9%, and 1.1% in 2019, 2020, and 2021, respectively; 99.6% (260 of 261) of CRE isolates were inhibited at an aztreonam-avibactam MIC of ≤8 mg/L. The CRE susceptibility to meropenem-vaborbactam decreased from 91.7% in 2019 to 83.1% in 2020 and 76.5% in 2021 (82.1% overall). The CRE, multidrug-resistant, and extensively drug-resistant phenotypes were markedly higher among isolates from pneumonia compared with other infections. The most common carbapenemase among CRE was Klebsiella pneumoniae carbapenemase (65.5% of CRE), followed by New Delhi metallo-β-lactamase (11.1%), oxacillinase (OXA)-48-like (4.6%), Serratia marcescens enzyme (2.3%), and imipenemase (1.5%). Among non-CPE-producing CRE isolates (n = 44; 16.9% of CRE), 97.7% were inhibited at ≤8 mg/L aztreonam-avibactam and 85.4% were meropenem-vaborbactam susceptible. The frequencies of MBL and OXA-48-type producers increased markedly. Aztreonam-avibactam demonstrated potent and consistent activity against Enterobacterales across infection types and over time.

Price transparency of prostate cancer care in the United States: An analysis of pricing and disclosure following the centers for medicare and medicaid mandate.

Starting January 1, 2021, Centers for Medicare and Medicaid Services required United States hospitals to publicly disclose prices of their services provided. We analyzed publicly-disclosed prices of prostate cancer-related services. All United States hospitals were queried for publicly-disclosed prices of total and free prostate-specific antigen, prostate magnetic resonance imaging, prostate biopsy, radical prostatectomy, and intensity-modulated radiation therapy as of May 2022. Prices were adjusted by regional price parity. Hospitals disclosing prices were compared with non-disclosing hospitals. Of 6013 hospitals, 3840 (64%) disclosed pricing for at least one prostate cancer-related service. Compared to non-disclosing hospitals, disclosing hospitals had higher median gross annual revenue ($318,502,426 vs. $62,930,436, p < 0.001) and were more likely to be non-profit (56% vs. 30%, p < 0.001), academic-affiliated (46% vs. 13%, p < 0.001), and in neighborhoods with low hospital density (68% vs 62%, p < 0.001). Self-pay prices were higher than insurance-negotiated prices for all services (p < 0.001) other than prostate biopsy. The range of pricing was widest for self-pay prostatectomy, with a 32-fold difference from 90th to 10th percentile ($47,445 to $1476). Self-pay prices of total prostate-specific antigen, magnetic resonance imaging, biopsy, intensity-modulated radiation therapy, and prostatectomy were higher at academic vs. non-academic, for-profit vs. non-profit hospitals, and hospitals in the top quartile of gross annual revenue vs. the third and fourth quartiles (p < 0.01). Self-pay prices of prostate biopsy and prostatectomy were higher in urban vs. rural neighborhoods and neighborhoods with high vs. low hospital density (p < 0.001). Self-pay prices of prostate cancer services were generally higher than insurance-negotiated prices and were higher at for-profit hospitals, academic hospitals, and hospitals in the highest quartile of gross annual revenue. Higher neighborhood hospital density was not associated with higher likelihood of price disclosure nor lower pricing of services, suggesting that local competition does not lead to lower prices and may disincentivize disclosure of prices.

Trends of β-Lactamase Occurrence Among Escherichia coli and Klebsiella pneumoniae in United States Hospitals During a 5-Year Period and Activity of Antimicrobial Agents Against Isolates Stratified by β-Lactamase Type.

The temporal and longitudinal trends of β-lactamases and their associated susceptibility patterns were analyzed for Escherichia coli and Klebsiella pneumoniae isolates consecutively collected in 56 United States hospitals during 2016-2020. Isolates (n = 19 453) were susceptibility tested by reference broth microdilution methods. Isolates that displayed minimum inhibitory concentration (MIC) values ≥2 mg/L for at least 2 of the following compounds-ceftazidime, ceftriaxone, aztreonam, or cefepime-or resistance to the carbapenems were submitted to whole genome sequencing for identification of β-lactamases. Longitudinal and temporal trends were determined by slope coefficient. New CTX-M and OXA-1 variants were characterized. Extended-spectrum β-lactamases (ESBLs) were detected among 88.0% of the isolates that displayed elevated cephalosporin/aztreonam MICs without carbapenem resistance. bla CTX-M-15 was detected among 55.5% of the ESBL producers. ESBL rates were stable over time, but significant increases were noted among bloodstream infection and K pneumoniae isolates, mainly driven by an increase in bla CTX-M. Carbapenem resistance and carbapenemase genes were noted among 166 and 145 isolates, respectively, including 137 bla KPC, 6 bla SME, 3 bla OXA-48-like, and 3 bla NDM. Ceftazidime-avibactam and carbapenems were very active (>99% susceptibility) against ESBL producers without carbapenem resistance. Ceftazidime-avibactam inhibited 97.0% of the carbapenem-resistant isolates. This agent and meropenem-vaborbactam inhibited 96.4% and 85.0% of the 2020 isolates, respectively. Overall, ESBL-producing isolates were stable, but an increase was noted for K pneumoniae isolates driven by CTX-M production. Carbapenem-resistant Enterobacterales rates decreased in the study period. The prevalence of metallo-β-lactamases and OXA-48-like remains low. Continuous surveillance of β-lactamase-producing isolates is prudent.

The effects of physicians on operational and financial performance in United States hospitals: staffing, human capital and knowledge spillovers

PurposeThe authors examine how physician staffing, human capital and knowledge spillovers are related to multiple dimensions of hospital operational and financial performance at the organizational level.Design/methodology/approachThe authors use a data set assembled from multiple sources for more than 1,300 US hospitals and employ hierarchical linear regression to test this study’s hypotheses. The authors use multiple quality, efficiency and financial measures of performance for these hospitals.FindingsThe authors find that higher levels of staffing, skills and knowledge spillovers associated with physicians were positively associated with multiple dimensions of hospital performance. The authors find linear and nonlinear relationships between experience and performance, with the relationships primarily negative, and nonlinear relationships between spillovers and quality performance.Practical implicationsHospital managers should consider increasing physician staffing levels if possible. In addition, the overall Final MIPS Score from the Centers for Medicare and Medicaid Services might be included as a factor in determining which physicians practice in a hospital. Finally, if possible, encouraging physicians to practice at multiple hospitals will likely be beneficial to hospital performance.Originality/valueThis study’s findings are original in that they explore how physician-specific staffing and human capital, which have received comparatively little attention in the literature, are related to several different dimensions of hospital-level operational and financial performance. To the best of the authors’ knowledge, this paper is also the first to examine the relationship between the construct of physician knowledge spillovers and hospital-level operational and financial performance.

North America Private Hospitals’ Service Quality Dimensions and patients’ satisfaction

In today's world, most industries use service quality in a variety of fields. The five service quality characteristics are tangible, assurance, reliability, responsiveness, and empathy, and they are being implemented across all industries. The primary goal of this study is to look into the quality of service provided by hospitals in North America and how that affects patients’ satisfaction. Furthermore, to determine which service quality factor has a greater impact than the others. The association between each service quality factor and visitor satisfaction was measured using a quantitative research method by the researcher. Patients in North America's hospitals were given a questionnaire that had been developed and circulated. In North America, 111 questionnaires were completed and received from hospitals patients. The findings revealed that the highest value was assigned to responsiveness as a service dimension, while the lowest value was assigned to assurance as a service dimension.&#x0D;

Variation in Cost of Echocardiography Within and Across United States Hospitals

While transthoracic echocardiography (TTE) is responsible for more Medicare spending than any other cardiovascular imaging procedure, little is known about its commercial cost footprint. The 2021 Hospital Price Transparency Final Rule mandated that U.S. hospitals publish their insurer-negotiated and self-pay prices for services. This study sought to characterize and assess factors contributing to variation in TTE prices. We used a commercial database containing hospital-disclosed prices to characterize variation in TTE prices within and across hospitals. We linked these price data to hospital and regional characteristics using Medicare Facility IDs. A total of 1,949 hospitals reported commercial prices. Among reporting hospitals, median commercial and self-pay prices were 2.93 and 3.06 times greater than the median Medicare price ($1,313 and $1,422, respectively, vs $464). Within hospitals, the 90th percentile payer-negotiated rate was 2.78 (interquartile range, 1.80-5.09) times the 10th percentile rate (within-center ratio). Across hospitals within the same hospital referral region, the median price at the 90th percentile hospital was 2.47 (interquartile range, 1.69-3.75) times that at the 10th percentile hospital (across-center ratio). On univariate analysis, for-profit (P=.04), teaching (P<.01), investor-owned (P<.01), and higher-rated hospitals (P<.01) charged higher prices, whereas rural referral centers (P=.01) and disproportionate share hospitals (P<.01) charged less. On multivariate analysis, the association between these characteristics and TTE prices persisted, except for investor ownership and rural referral centers. Self-pay and commercial TTE prices were higher than Medicare prices and varied significantly within and across hospitals. For-profit, teaching, and higher-rated hospitals had higher prices, in contrast to DSH hospitals. A better understanding of the relationship between this cost variation and quality of care is critical given the impact of cost on health care access and affordability.

Acute respiratory distress syndrome after SARS-CoV-2 infection on young adult population: International observational federated study based on electronic health records through the 4CE consortium.

In young adults (18 to 49 years old), investigation of the acute respiratory distress syndrome (ARDS) after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been limited. We evaluated the risk factors and outcomes of ARDS following infection with SARS-CoV-2 in a young adult population. A retrospective cohort study was conducted between January 1st, 2020 and February 28th, 2021 using patient-level electronic health records (EHR), across 241 United States hospitals and 43 European hospitals participating in the Consortium for Clinical Characterization of COVID-19 by EHR (4CE). To identify the risk factors associated with ARDS, we compared young patients with and without ARDS through a federated analysis. We further compared the outcomes between young and old patients with ARDS. Among the 75,377 hospitalized patients with positive SARS-CoV-2 PCR, 1001 young adults presented with ARDS (7.8% of young hospitalized adults). Their mortality rate at 90 days was 16.2% and they presented with a similar complication rate for infection than older adults with ARDS. Peptic ulcer disease, paralysis, obesity, congestive heart failure, valvular disease, diabetes, chronic pulmonary disease and liver disease were associated with a higher risk of ARDS. We described a high prevalence of obesity (53%), hypertension (38%- although not significantly associated with ARDS), and diabetes (32%). Trough an innovative method, a large international cohort study of young adults developing ARDS after SARS-CoV-2 infection has been gather. It demonstrated the poor outcomes of this population and associated risk factor.

Burden of firearm-related injuries as associated secondary diagnosis in the United States from National Inpatient Sample Dataset.

There is little known about the differences, from the point of view of healthcare resource utilization, between non-fatal versus fatal firearm-related injuries. We undertook this research project utilizing the National Inpatient Sample (NIS) database to address this critical knowledge gap. Our aims for this study were to describe the patterns of FRI in the United States during the period of 2016-2019 and to evaluate the patient-centered outcomes in the survivor (non-fatal injuries) versus the non-survivor (fatal injuries) groups. We used the National Inpatient Sample (NIS) Database, 2016-2019 (5) (~ 20% of United States hospitalizations) to identify patients with an associated diagnosis of firearm-related injuries (FRI) [Gibson T et al (2016) in Agency for Healthcare Research and Quality 2016-02]. We found that the individuals from the lowest quartile of annual household income, males, young Americans, and racial minorities were disproportionally affected The non-survivor (fatal injuries) group had a shorter length of stay in the hospital by 5.1days (95% CI -5.64 to -4.58, p value = < 0.01), the higher median cost of hospitalization by $8903 (95% confidence interval $311.9 to $17,494.2, p value = 0.04), and a higher median cost of hospitalization per day by $41,576.74 (95% confidence interval $ 40,333.1 to $42,820.3, p value = < 0.01). In conclusion, the individuals from the lowest quartile of annual household income, males, young Americans and racial minorities were disproportionally affected. Firearm-related injuries pose a persistent healthcare cost burden with the cumulative and per day cost of hospitalization for fatal injuries being significantly higher than the non-fatal injuries despite a shorter hospital LOS.
