Background: Bivalent mRNA vaccines were recommended since September 2022. However, coverage with a recent vaccine dose has been limited, and there are few robust estimates of bivalent VE against symptomatic SARS-CoV-2 infection (COVID-19). We estimated VE of a bivalent mRNA vaccine dose against COVID-19 among eligible U.S. healthcare personnel who had previously received monovalent mRNA vaccine doses., Methods: We conducted a case-control study in 22 U.S. states, and enrolled healthcare personnel with COVID-19 (case-participants) or without COVID-19 (control-participants) during September 2022-May 2023. Participants were considered eligible for a bivalent mRNA dose if they had received 2-4 monovalent (ancestral-strain) mRNA vaccine doses, and were ≥67 days after the most recent vaccine dose. We estimated VE of a bivalent mRNA dose using conditional logistic regression, accounting for matching by region and four-week calendar period. We adjusted estimates for age group, sex, race and ethnicity, educational level, underlying health conditions, community COVID-19 exposure, prior SARS-CoV-2 infection, and days since the last monovalent mRNA dose., Results: Among 3,647 healthcare personnel, 1,528 were included as case-participants and 2,119 as control-participants. Participants received their last monovalent mRNA dose a median of 404 days previously; 1,234 (33.8%) also received a bivalent mRNA dose a median of 93 days previously. Overall, VE of a bivalent dose was 34.1% (95% CI, 22.6%-43.9%) against COVID-19 and was similar by product, days since last monovalent dose, number of prior doses, age group, and presence of underlying health conditions. However, VE declined from 54.8% (95% CI, 40.7%-65.6%) after 7-59 days to 21.6% (95% CI 5.6%-34.9%) after ≥60 days., Conclusions: Bivalent mRNA COVID-19 vaccines initially conferred approximately 55% protection against COVID-19 among U.S. healthcare personnel. However, protection waned after two months. These findings indicate moderate initial protection against symptomatic SARS-CoV-2 infection by remaining up-to-date with COVID-19 vaccines., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Monica Brackney owned stock in Moderna from November 2022–April 2023 stock as part of portfolio managed by Parametric Investments Portfolio LLC.

Enhancing quality of prescribing practices for older adults discharged from the Emergency Department (EQUIPPED) aims to reduce the monthly proportion of potentially inappropriate medications (PIMs) prescribed to older adults discharged from the ED to 5% or less. We describe prescribing outcomes at three academic health systems adapting and sequentially implementing the EQUIPPED medication safety programme.EQUIPPED was adapted from a model developed in the Veterans Health Administration (VA) and sequentially implemented in one academic health system per year over a 3-year period. The monthly proportion of PIMs, as defined by the 2015 American Geriatrics Beers Criteria, of all medications prescribed to adults aged 65 years and older at discharge was assessed for 6 months preimplementation until 12 months postimplementation using a generalised linear time series model with a Poisson distribution.The EQUIPPED programme was translated from the VA health system and its electronic medical record into three health systems each using a version of the Epic electronic medical record. Adaptation occurred through local modification of order sets and in the generation and delivery of provider prescribing reports by local champions. Baseline monthly PIM proportions 6 months prior to implementation at the three sites were 5.6% (95% CI 5.0% to 6.3%), 5.8% (95% CI 5.0% to 6.6%) and 7.3% (95% CI 6.4% to 9.2%), respectively. Evaluation of monthly prescribing including the twelve months post-EQUIPPED implementation demonstrated significant reduction in PIMs at one of the three sites. In exploratory analyses, the proportion of benzodiazepine prescriptions decreased across all sites from approximately 17% of PIMs at baseline to 9.5%-12% postimplementation, although not all reached statistical significance.EQUIPPED is feasible to implement outside the VA system. While the impact of the EQUIPPED model may vary across different health systems, results from this initial translation suggest significant reduction in specific high-risk drug classes may be an appropriate target for improvement at sites with relatively low baseline PIM prescribing rates., (© Author(s) (or their employer(s)) 2021.

Objectives: To present the three-site EQUIPPED academic health system research collaborative, which engaged in sequential implementation of the EQUIPPED medication safety program, as a learning health system; to understand how the organizations worked together to build resources for program scale-up., Design: Following the Replicating Effective Programs framework, we analyzed content from implementation teams' focus groups, local and cross-site meeting minutes and sites' organizational profiles to develop an implementation package., Setting: Three academic emergency departments that each implemented EQUIPPED over three successive years., Participants: Implementation team members at each site participating in focus groups (n = 18), local meetings during implementation years, and cross-site meetings during all years of the projects., Intervention(s): EQUIPPED provides Emergency Department providers with clinical decision support (education, order sets, and feedback) to reduce prescribing of potentially inappropriate medications to adults aged 65 years and older who received a prescription at time of discharge., Main Outcome Measure(s): Implementation process components assembled through successive implementation., Results: Each site had clinical and environmental characteristics to be addressed in implementing the EQUIPPED program. We identified 10 process elements and describe lessons for each. Lessons guided the compilation of the EQUIPPED intervention package or toolkit, including the EQUIPPED logic model., Conclusions: Our academic health system research collaborative addressing medication safety through sequential implementation is a learning health system that can serve as a model for other quality improvement projects with multiple sites. The network produced an implementation package that can be vetted, piloted, evaluated, and finalized for large-scale dissemination in community-based settings., (© The Author(s) 2020.

Traumatic brain injury (TBI) is a leading cause of death worldwide and is increasing exponentially particularly in low and middle income countries (LMIC). To inform the development of a standard Clinical Practice Guideline (CPG) for the acute management of TBI that can be implemented specifically for limited resource settings, we conducted a systematic review to identify and assess the quality of all currently available CPGs on acute TBI using the AGREE II instrument. In accordance with PRISMA guidelines, from April 2013 to December 2015 we searched MEDLINE, EMBASE, Google Scholar and the Duke University Medical Center Library Guidelines for peer-reviewed published Clinical Practice Guidelines on the acute management of TBI (less than 24 hours), for any level of traumatic brain injury in both high and low income settings. A comprehensive reference and citation analysis was performed. CPGs found were assessed using the AGREE II instrument by five independent reviewers and scores were aggregated and reported in percentage of total possible score. An initial 2742 articles were evaluated with an additional 98 articles from the citation and reference analysis, yielding 273 full texts examined. A total of 24 final CPGs were included, of which 23 were from high income countries (HIC) and 1 from LMIC. Based on the AGREE II instrument, the best score on overall assessment was 100.0 for the CPG from the National Institute for Health and Clinical Excellence (NIHCE, 2007), followed by the New Zealand Guidelines Group (NZ, 2006) and the National Clinical Guideline (SIGN, 2009) both with a score of 96.7. The CPG from a LMIC had lower scores than CPGs from higher income settings. Our study identified and evaluated 24 CPGs with the highest scores in clarity and presentation, scope and purpose, and rigor of development. Most of these CPGs were developed in HICs, with limited applicability or utility for resource limited settings. Stakeholder involvement, Applicability, and Editorial independence remain weak and insufficiently described specifically with piloting, addressing potential costs and implementation barriers, and auditing for quality improvement., Competing Interests: The authors have declared that no competing interests exist.

Offenders with mental illness challenge forensic systems throughout the world. Those with personality disorders present additional challenges. In this article, the authors describe relevant German legislation and the consequent forensic treatment of personality-disordered offenders in the German psychiatric and correctional systems, with a focus on the German state of Hessen. The development of laws and regulations are addressed, as are the parallels and distinctions between forensic hospitals and correctional settings. Current treatment approaches and programs are described. Research initiatives and future directions for the system, and comparisons with the system in the United States conclude the article.

Background: The aim of this study was to assess the potential for future violent behaviour comparing patients recruited from forensic and general psychiatric wards in Germany., Patients and Methods: Fifty patients were recruited from a forensic hospital and 29 from a general psychiatric hospital. In the weeks preceding discharge, structured assessments of the future risk of violent behaviour were completed using the HCR-20., Results: There was little difference in the risk presented by the two groups. Forensic patients presented an elevated risk of violence because of historical factors, while the risk among patients from general psychiatry was due to clinical symptoms., Conclusion: Some criminal offences could be prevented if more time and effort were spent in general psychiatric practice in identifying patients at high risk for violence and in reducing symptoms of psychoses before discharge.

We sought to extract additional physiological information from the time-dependent left ventricular (LV) pressure contour and thereby gain new insights into ventricular function. We used phase plane analysis to characterize high-fidelity pressure data in selected subjects undergoing elective cardiac catheterization. The standard hemodynamic indexes of LV systolic and diastolic function derived from the time-dependent LV pressure contour could be easily obtained using the phase plane method. Additional novel attributes of the phase plane pressure loop, such as phase plane pressure loop area, graphical representation of the isovolumic relaxation time constant, and quantitative measures of beat-to-beat systolic-diastolic coupling were characterized. The asymmetry between the pressures at which maximum isovolumic pressure rise and pressure fall occur, as well as their load dependence, were also easily quantitated. These results indicate that the phase plane method provides a novel window for physiological discovery and has theoretical and applied advantages in quantitative ventricular function characterization.
