Monovalent COVID-19 mRNA vaccines, designed against the ancestral strain of SARS-CoV-2, successfully reduced COVID-19-related morbidity and mortality in the United States and globally (1,2). However, vaccine effectiveness (VE) against COVID-19-associated hospitalization has declined over time, likely related to a combination of factors, including waning immunity and, with the emergence of the Omicron variant and its sublineages, immune evasion (3). To address these factors, on September 1, 2022, the Advisory Committee on Immunization Practices recommended a bivalent COVID-19 mRNA booster (bivalent booster) dose, developed against the spike protein from ancestral SARS-CoV-2 and Omicron BA.4/BA.5 sublineages, for persons who had completed at least a primary COVID-19 vaccination series (with or without monovalent booster doses) ≥2 months earlier (4). Data on the effectiveness of a bivalent booster dose against COVID-19 hospitalization in the United States are lacking, including among older adults, who are at highest risk for severe COVID-19-associated illness. During September 8-November 30, 2022, the Investigating Respiratory Viruses in the Acutely Ill (IVY) Network§ assessed effectiveness of a bivalent booster dose received after ≥2 doses of monovalent mRNA vaccine against COVID-19-associated hospitalization among immunocompetent adults aged ≥65 years. When compared with unvaccinated persons, VE of a bivalent booster dose received ≥7 days before illness onset (median = 29 days) against COVID-19-associated hospitalization was 84%. Compared with persons who received ≥2 monovalent-only mRNA vaccine doses, relative VE of a bivalent booster dose was 73%. These early findings show that a bivalent booster dose provided strong protection against COVID-19-associated hospitalization in older adults and additional protection among persons with previous monovalent-only mRNA vaccination. All eligible persons, especially adults aged ≥65 years, should receive a bivalent booster dose to maximize protection against COVID-19 hospitalization this winter season. Additional strategies to prevent respiratory illness, such as masking in indoor public spaces, should also be considered, especially in areas where COVID-19 community levels are high (4,5).

Medical errors are common and often lead to feelings of self-doubt, helplessness, and guilt. Society thinks of physicians as healers, and physicians who see their role as offering a cure will always feel as if they haven't done enough. This article discusses five steps in the management of medical and surgical error: (1) care for the patient and family, (2) report to appropriate sources, (3) review the incident, (4) manage legal issues, and (5) engage in self-care. There is a focus on managing grief, with tips for coping. [ABSTRACT FROM AUTHOR]

The success of a journal club hinges on the presentation of articles that are both relevant and scientifically robust. It's insufficient for presenters to merely read through an article and highlight a few points without a clear focus. A strong presentation should thoroughly describe the relevance and validity of the study, offer a critique, suggest how further research might address the issue, and discuss the implications for patient care. Selecting the right article is crucial. It is recommended to begin the presentation with a case scenario to emphasize the article's clinical relevance and to revisit the case at the conclusion of the presentation. The components of the article presentation should include background information, methodology and results, and the authors' discussion. Additionally, the presenter should critique the article's validity, noting any potential biases, evaluating the risks and costs of the proposed intervention, and assessing how well the article supports its hypothesis. The presentation should conclude with a summary statement that includes conclusions, implications, and future directions. Having a structured process for journal club presentations guides presenters and ensures that attendees derive maximum benefit from the educational activity. This organized approach fosters a deeper understanding and encourages critical thinking among participants. [ABSTRACT FROM AUTHOR]

To increase medical students' and residents' understanding and retention, faculty need to teach from a knowledge standpoint and understanding of how individuals learn. We know from cognitive information processing that learners remember only a small portion of what they read or hear but remember up to 90% of information when strong active learning modalities are included. Faculty also need to be aware of different learning styles—kinesthetic, visual, and auditory—and ensure that they are including methods that can reach all learners. The cognitive and information processing theories of learning provide insights to educators related to building on prior knowledge from learning and limiting the number of points taught so learners can process and retain the information. Strategies such as a flipped classroom model and question clicker technology can assist in reaching learning goals. Fundamental conditions for learning include awareness, interest, motivation, relevance, engagement, reinforcement, and support. [ABSTRACT FROM AUTHOR]

Baylor University Medical Center benefits from being a quaternary care center with 900+ licensed beds and multiple different models to staff patients on the hospitalist service. These models include hospitalist only, resident teaching teams, and two different advanced practice practitioner teams. The primary goal of this study was to assess these different staffing models and to ascertain which model, if any, has better outcomes related to length of stay, total hospital charges, 30-day readmission rates, patient satisfaction, hospital-acquired infections, mortality, and early discharges. The study was an observational retrospective chart review of all discharges from the hospitalist service at Baylor University Medical Center from October 1, 2021, to February 28, 2022. Patients were included if the hospitalist team was the primary team of record at the time of discharge. A total of 7803 patients were included. There was no difference in patient satisfaction, hospital-acquired infections, and mortality between the groups. The teaching teams had a shorter length of stay before the removal of outliers. Independent advanced practice practitioners reliably had more patients discharged before 11:30 am. Results support the concept of continuity of care, as well as lower patient-to-provider ratios. These results have actionable implications that support the use of different advanced practice practitioner teams for the safe care of hospitalized patients as well as the safe integration of residents into patient care.

COVID-19 vaccination averted approximately 68,000 hospitalizations during the 2023-24 respiratory season. In June 2024, CDC and the Advisory Committee on Immunization Practices (ACIP) recommended that all persons aged ≥6 months receive a 2024-2025 COVID-19 vaccine, which targets Omicron JN.1 and JN.1-derived sublineages. Interim effectiveness of 2024-2025 COVID-19 vaccines was estimated against COVID-19-associated emergency department (ED) or urgent care (UC) visits during September 2024-January 2025 among adults aged ≥18 years in one CDC-funded vaccine effectiveness (VE) network, against COVID-19-associated hospitalization in immunocompetent adults aged ≥65 years in two networks, and against COVID-19-associated hospitalization among adults aged ≥65 years with immunocompromising conditions in one network. Among adults aged ≥18 years, VE against COVID-19-associated ED/UC visits was 33% (95% CI = 28%-38%) during the first 7-119 days after vaccination. Among immunocompetent adults aged ≥65 years from two CDC networks, VE estimates against COVID-19-associated hospitalization were 45% (95% CI = 36%-53%) and 46% (95% CI = 26%-60%) during the first 7-119 days after vaccination. Among adults aged ≥65 years with immunocompromising conditions in one network, VE was 40% (95% CI = 21%-54%) during the first 7-119 days after vaccination. These findings demonstrate that vaccination with a 2024-2025 COVID-19 vaccine dose provides additional protection against COVID-19-associated ED/UC encounters and hospitalizations compared with not receiving a 2024-2025 dose and support current CDC and ACIP recommendations that all persons aged ≥6 months receive a 2024-2025 COVID-19 vaccine dose., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Background: clinical guidelines recommend initiation of antiviral therapy as soon as possible for patients hospitalized with confirmed or suspected influenza., Methods: A multicenter US observational sentinel surveillance network prospectively enrolled adults (aged ≥18 years) hospitalized with laboratory-confirmed influenza at 24 hospitals during October 1, 2022-July 21, 2023. A multivariable proportional odds model was used to compare peak pulmonary disease severity (no oxygen support, standard supplemental oxygen, high-flow oxygen/non-invasive ventilation, invasive mechanical ventilation, or death) after the day of hospital admission among patients starting oseltamivir treatment on the day of admission (early) versus those who did not (late or not treated), adjusting for baseline (admission day) severity, age, sex, site, and vaccination status. Multivariable logistic regression models were used to evaluate the odds of intensive care unit (ICU) admission, acute kidney replacement therapy or vasopressor use, and in-hospital death., Results: A total of 840 influenza-positive patients were analyzed, including 415 (49%) who started oseltamivir treatment on the day of admission, and 425 (51%) who did not. Compared with late or not treated patients, those treated early had lower peak pulmonary disease severity (proportional aOR: 0.60, 95% CI: 0.49-0.72), and lower odds of intensive care unit admission (aOR: 0.24, 95% CI: 0.13-0.47), acute kidney replacement therapy or vasopressor use (aOR: 0.40, 95% CI: 0.22-0.67), and in-hospital death (aOR: 0.36, 95% CI: 0.18-0.72)., Conclusion: Among adults hospitalized with influenza, treatment with oseltamivir on day of hospital admission was associated reduced risk of disease progression, including pulmonary and extrapulmonary organ failure and death., (Published by Oxford University Press on behalf of Infectious Diseases Society of America 2024.)

Background: Assessments of COVID-19 vaccine effectiveness are needed to monitor the protection provided by updated vaccines against severe COVID-19. We evaluated the effectiveness of original monovalent and bivalent (ancestral strain and Omicron BA.4/5) COVID-19 vaccination against COVID-19-associated hospitalization and severe in-hospital outcomes., Methods: During September 8, 2022 to August 31, 2023, adults aged ≥ 18 years hospitalized with COVID-19-like illness were enrolled at 26 hospitals in 20 US states. Using a test-negative case-control design, we estimated vaccine effectiveness (VE) with multivariable logistic regression adjusted for age, sex, race/ethnicity, admission date, and geographic region., Results: Among 7028 patients, 2924 (41.6%) were COVID-19 case patients, and 4104 (58.4%) were control patients. Compared to unvaccinated patients, absolute VE against COVID-19-associated hospitalization was 6% (-7%-17%) for original monovalent doses only (median time since last dose [IQR] = 421 days [304-571]), 52% (39%-61%) for a bivalent dose received 7-89 days earlier, and 13% (-10%-31%) for a bivalent dose received 90-179 days earlier. Absolute VE against COVID-19-associated invasive mechanical ventilation or death was 51% (34%-63%) for original monovalent doses only, 61% (35%-77%) for a bivalent dose received 7-89 days earlier, and 50% (11%-71%) for a bivalent dose received 90-179 days earlier., Conclusion: Bivalent vaccination provided protection against COVID-19-associated hospitalization and severe in-hospital outcomes within 3 months of receipt, followed by a decline in protection to a level similar to that remaining from previous original monovalent vaccination by 3-6 months. These results underscore the benefit of remaining up to date with recommended COVID-19 vaccines., (Published 2024. This article is a U.S. Government work and is in the public domain in the USA.

Background: Influenza circulation during the 2022-2023 season in the United States largely returned to pre-coronavirus disease 2019 (COVID-19)-pandemic patterns and levels. Influenza A(H3N2) viruses were detected most frequently this season, predominately clade 3C.2a1b.2a, a close antigenic match to the vaccine strain., Methods: To understand effectiveness of the 2022-2023 influenza vaccine against influenza-associated hospitalization, organ failure, and death, a multicenter sentinel surveillance network in the United States prospectively enrolled adults hospitalized with acute respiratory illness between 1 October 2022, and 28 February 2023. Using the test-negative design, vaccine effectiveness (VE) estimates against influenza-associated hospitalization, organ failures, and death were measured by comparing the odds of current-season influenza vaccination in influenza-positive case-patients and influenza-negative, SARS-CoV-2-negative control-patients., Results: A total of 3707 patients, including 714 influenza cases (33% vaccinated) and 2993 influenza- and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-negative controls (49% vaccinated) were analyzed. VE against influenza-associated hospitalization was 37% (95% confidence interval [CI]: 27%-46%) and varied by age (18-64 years: 47% [30%-60%]; ≥65 years: 28% [10%-43%]), and virus (A[H3N2]: 29% [6%-46%], A[H1N1]: 47% [23%-64%]). VE against more severe influenza-associated outcomes included: 41% (29%-50%) against influenza with hypoxemia treated with supplemental oxygen; 65% (56%-72%) against influenza with respiratory, cardiovascular, or renal failure treated with organ support; and 66% (40%-81%) against influenza with respiratory failure treated with invasive mechanical ventilation., Conclusions: During an early 2022-2023 influenza season with a well-matched influenza vaccine, vaccination was associated with reduced risk of influenza-associated hospitalization and organ failure., Competing Interests: Potential conflicts of interest.

Importance: On June 21, 2023, the Centers for Disease Control and Prevention recommended the first respiratory syncytial virus (RSV) vaccines for adults aged 60 years and older using shared clinical decision-making. Understanding the severity of RSV disease in adults can help guide this clinical decision-making., Objective: To describe disease severity among adults hospitalized with RSV and compare it with the severity of COVID-19 and influenza disease by vaccination status., Design, Setting, and Participants: In this cohort study, adults aged 18 years and older admitted to the hospital with acute respiratory illness and laboratory-confirmed RSV, SARS-CoV-2, or influenza infection were prospectively enrolled from 25 hospitals in 20 US states from February 1, 2022, to May 31, 2023. Clinical data during each patient's hospitalization were collected using standardized forms. Data were analyzed from August to October 2023., Exposures: RSV, SARS-CoV-2, or influenza infection., Main Outcomes and Measures: Using multivariable logistic regression, severity of RSV disease was compared with COVID-19 and influenza severity, by COVID-19 and influenza vaccination status, for a range of clinical outcomes, including the composite of invasive mechanical ventilation (IMV) and in-hospital death., Results: Of 7998 adults (median [IQR] age, 67 [54-78] years; 4047 [50.6%] female) included, 484 (6.1%) were hospitalized with RSV, 6422 (80.3%) were hospitalized with COVID-19, and 1092 (13.7%) were hospitalized with influenza. Among patients with RSV, 58 (12.0%) experienced IMV or death, compared with 201 of 1422 unvaccinated patients with COVID-19 (14.1%) and 458 of 5000 vaccinated patients with COVID-19 (9.2%), as well as 72 of 699 unvaccinated patients with influenza (10.3%) and 20 of 393 vaccinated patients with influenza (5.1%). In adjusted analyses, the odds of IMV or in-hospital death were not significantly different among patients hospitalized with RSV and unvaccinated patients hospitalized with COVID-19 (adjusted odds ratio [aOR], 0.82; 95% CI, 0.59-1.13; P = .22) or influenza (aOR, 1.20; 95% CI, 0.82-1.76; P = .35); however, the odds of IMV or death were significantly higher among patients hospitalized with RSV compared with vaccinated patients hospitalized with COVID-19 (aOR, 1.38; 95% CI, 1.02-1.86; P = .03) or influenza disease (aOR, 2.81; 95% CI, 1.62-4.86; P < .001)., Conclusions and Relevance: Among adults hospitalized in this US cohort during the 16 months before the first RSV vaccine recommendations, RSV disease was less common but similar in severity compared with COVID-19 or influenza disease among unvaccinated patients and more severe than COVID-19 or influenza disease among vaccinated patients for the most serious outcomes of IMV or death.

In September 2023, CDC's Advisory Committee on Immunization Practices recommended updated 2023-2024 (monovalent XBB.1.5) COVID-19 vaccination for all persons aged ≥6 months to prevent COVID-19, including severe disease. However, few estimates of updated vaccine effectiveness (VE) against medically attended illness are available. This analysis evaluated VE of an updated COVID-19 vaccine dose against COVID-19-associated emergency department (ED) or urgent care (UC) encounters and hospitalization among immunocompetent adults aged ≥18 years during September 2023-January 2024 using a test-negative, case-control design with data from two CDC VE networks. VE against COVID-19-associated ED/UC encounters was 51% (95% CI = 47%-54%) during the first 7-59 days after an updated dose and 39% (95% CI = 33%-45%) during the 60-119 days after an updated dose. VE estimates against COVID-19-associated hospitalization from two CDC VE networks were 52% (95% CI = 47%-57%) and 43% (95% CI = 27%-56%), with a median interval from updated dose of 42 and 47 days, respectively. Updated COVID-19 vaccine provided increased protection against COVID-19-associated ED/UC encounters and hospitalization among immunocompetent adults. These results support CDC recommendations for updated 2023-2024 COVID-19 vaccination. All persons aged ≥6 months should receive updated 2023-2024 COVID-19 vaccine., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

On June 21, 2023, CDC's Advisory Committee on Immunization Practices recommended respiratory syncytial virus (RSV) vaccination for adults aged ≥60 years, offered to individual adults using shared clinical decision-making. Informed use of these vaccines requires an understanding of RSV disease severity. To characterize RSV-associated severity, 5,784 adults aged ≥60 years hospitalized with acute respiratory illness and laboratory-confirmed RSV, SARS-CoV-2, or influenza infection were prospectively enrolled from 25 hospitals in 20 U.S. states during February 1, 2022-May 31, 2023. Multivariable logistic regression was used to compare RSV disease severity with COVID-19 and influenza severity on the basis of the following outcomes: 1) standard flow (<30 L/minute) oxygen therapy, 2) high-flow nasal cannula (HFNC) or noninvasive ventilation (NIV), 3) intensive care unit (ICU) admission, and 4) invasive mechanical ventilation (IMV) or death. Overall, 304 (5.3%) enrolled adults were hospitalized with RSV, 4,734 (81.8%) with COVID-19 and 746 (12.9%) with influenza. Patients hospitalized with RSV were more likely to receive standard flow oxygen, HFNC or NIV, and ICU admission than were those hospitalized with COVID-19 or influenza. Patients hospitalized with RSV were more likely to receive IMV or die compared with patients hospitalized with influenza (adjusted odds ratio = 2.08; 95% CI = 1.33-3.26). Among hospitalized older adults, RSV was less common, but was associated with more severe disease than COVID-19 or influenza. High disease severity in older adults hospitalized with RSV is important to consider in shared clinical decision-making regarding RSV vaccination., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

As of April 2023, the COVID-19 pandemic has resulted in 1.1 million deaths in the United States, with approximately 75% of deaths occurring among adults aged ≥65 years (1). Data on the durability of protection provided by monovalent mRNA COVID-19 vaccination against critical outcomes of COVID-19 are limited beyond the Omicron BA.1 lineage period (December 26, 2021-March 26, 2022). In this case-control analysis, the effectiveness of 2-4 monovalent mRNA COVID-19 vaccine doses was evaluated against COVID-19-associated invasive mechanical ventilation (IMV) and in-hospital death among immunocompetent adults aged ≥18 years during February 1, 2022-January 31, 2023. Vaccine effectiveness (VE) against IMV and in-hospital death was 62% among adults aged ≥18 years and 69% among those aged ≥65 years. When stratified by time since last dose, VE was 76% at 7-179 days, 54% at 180-364 days, and 56% at ≥365 days. Monovalent mRNA COVID-19 vaccination provided substantial, durable protection against IMV and in-hospital death among adults during the Omicron variant period. All adults should remain up to date with recommended COVID-19 vaccination to prevent critical COVID-19-associated outcomes., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

In December 2019, China witnessed the emergence of a novel coronavirus, SARS-CoV-2. Its ability to spread quickly made it a global pandemic. The United States has been greatly affected, with more than 980,000 lives lost so far. Diagnosis is made primarily through nasopharyngeal swab for polymerase chain reaction. Point-of-care testing by antigen is less sensitive and specific and may require polymerase chain reaction confirmation. Management of the COVID-19 patient remains largely supportive. Steroids are now a therapy mainstay if the patient is hypoxic. Direct antivirals, such as nirmatrelvir/ritonavir, remdesivir, or molnupirivir, can be used if certain criteria are met. SARS-CoV-2 is transmitted primarily by inhalation of large droplets, though transmission by aerosolization may occur, particularly via certain procedures. In the hospital setting, use of personal protective equipment for the care of COVID-19 patients has largely remained the same, with full use of gowns, gloves, respirators, and eye protection. Inadequate supply at the start of the pandemic required innovative ways to reprocess and extend the use of personal protective equipment. Three vaccines are now available in the US, all with excellent efficacy against severe disease and hospitalization, though booster doses are needed to bolster waning antibody levels. The possibility of emerging variants continues to remain a threat to control of the pandemic.

The coronavirus (CoV) epidemic that began in China in December 2019 follows earlier epidemics of severe acute respiratory syndrome CoV in China and Middle East respiratory syndrome CoV in Saudi Arabia. The full genome of the 2019 novel coronavirus (2019-nCoV) has now been shared, and data have been gathered from several case series. As of February 11, 2020, there have been 45,182 laboratory-confirmed cases, the vast majority in China, with 1115 deaths, for an overall case-fatality rate of 2.5%. Cases have been confirmed in 27 countries. On average, each patient infects 2.2 other people. Symptomatic infection appears to predominantly affect adults, with a 5-day estimated incubation period between infection and symptom onset. The most common presenting symptoms are fever, cough, dyspnea, and myalgias and/or fatigue. All cases reported to date have shown radiographic evidence of pneumonia. 2019-nCoV is diagnosed by real-time reverse transcriptase polymerase chain reaction. Treatment is largely supportive, with regimens including antiviral therapy. Corticosteroids are not routinely recommended. Hand hygiene, prompt identification and isolation of suspect patients, and appropriate use of personal protective equipment are the most reliable methods to contain the epidemic., (Copyright © 2020 Baylor University Medical Center.)

Poor social support is associated with adverse obstetric outcomes. Maternity group homes (MGHs), residential programs for pregnant women, have been found to improve social support in small studies. The present study aimed to verify these previous studies, discover whether there is a group of women whom MGHs most benefit, identify what services offer that benefit, and identify how to predict who will most benefit from MGH admission. Forty-three US MGHs from 14 states were surveyed from August 2015 to February 2017. The primary outcome was self-reported social support before and during MGH admission. The secondary outcome was the perception that MGH admission would help current and future relationships. Among 95 respondents, 54% perceived better in-MGH support compared to pre-MGH support. Women with poor pre-MGH support reported improvement; the converse was true of high pre-MGH support ( P  < 0.001). A total of 77% to 82% of participants anticipated that MGH admission would help current and future relationships, including 91% to 92% of women with stable or increased in-MGH support ( P  = 0.07 current, P  < 0.01 future). Participants with increased in-MGH support reported more services as helpful ( P  < 0.05). In summary, MGHs are associated with improved support and relationships for most residents. The support score may identify which women may benefit most from MGH admission.

Central line-associated bloodstream infections (CLABSIs) are one of the most dangerous and costly types of hospital-acquired infections. Incidence of CLABSI can be significantly reduced through proper aseptic techniques, surveillance, and active management strategies, including elimination of idle central line days. This quality improvement project examined two central venous catheter (CVC) cohorts. The institutional electronic health record (EHR) was utilized to generate a daily report indicating CVC utilization by patient care unit. The EHR was further scrutinized for documentation of appropriate indications for CVC use employing an appropriateness tool developed by the institutional vascular access team. Cohort 1 included 12 National Healthcare Safety Network-reportable units audited on a daily basis over a 4-week time period; cohort 2 included selected National Healthcare Safety Network-nonreportable units audited on a daily basis over a 2-week time period. Central venous catheters that did not meet defined indications as outlined by the institutional vascular access team's data collection checklist were escalated the same day to the unit clinical nurse manager for review and possible removal. The percentage of clinically nonindicated CVCs in cohort 1 fell by 65% over the 4-week period of daily audit and real-time feedback, with similar results noted for cohort 2. In conclusion, real-time audit and feedback regarding appropriate clinical indications for CVC use can result in decreased idle or nonindicated central line days, potentially contributing to decreased CLABSI rates.

West Nile virus (WNV) has been responsible for multiple outbreaks and has shown evolution in its clinical manifestation. The Centers for Disease Control and Prevention has provided diagnostic criteria in classifying the variety of WNV infection; however, application of these criteria can prove challenging during outbreaks, and understanding the array of presentations and patient population is clinically important. In this article, we present the challenges encountered during the 2012 outbreak at one institution.
