    Abstract Background: This study evaluated the relationship between Joint Commission accreditation and health care-associated infections (HAIs) in long-term care hospitals (LTCHs).
    Methods: This observational study used Centers for Medicare & Medicaid Services (CMS) LTCH data for the period 2017 to June 2021. The standardized infection ratio (SIR) of three measures used by the Centers for Disease Control and Prevention's National Healthcare Safety Network were used as dependent variables in a random coefficient Poisson regression model (adjusting for CMS region, owner type, and bed size quartile): catheter-associated urinary tract infections (CAUTIs), Clostridioides difficile infections (CDIs), and central line-associated bloodstream infections (CLABSIs) for the periods 2017 to 2019 and July 1, 2020, to June 30, 2021. Data from January 1 to June 30, 2020, were excluded due to the COVID-19 pandemic.
    Results: The data set included 244 (73.3%) Joint Commission-accredited and 89 (26.7%) non-Joint Commission-accredited LTCHs. Compared to non-Joint Commission-accredited LTCHs, accredited LTCHs had significantly better (lower) SIRs for CLABSI and CAUTI measures, although no differences were observed for CDI SIRs. There were no significant differences in year trends for any of the HAI measures. For each year of the study period, a greater proportion of Joint Commission-accredited LTCHs performed significantly better than the national benchmark for all three measures (p = 0.04 for CAUTI, p = 0.02 for CDI, p = 0.01 for CLABSI).
    Conclusion: Although this study was not designed to establish causality, positive associations were observed between Joint Commission accreditation and CLABSI and CAUTI measures, and Joint Commission-accredited LTCHs attained more consistent high performance over the four-year study period for all three measures. Influencing factors may include the focus of Joint Commission standards on infection control and prevention (ICP), including the hierarchical approach to selecting ICP-related standards as inputs into LTCH policy.

    Abstract Objectives: As we pass the anniversary of the declaration of a global pandemic by the World Health Organisation, it invites us to reflect upon the inescapable changes that coronavirus has wrought upon ENT and, in particular, rhinological practice. As it remains unclear when we will emerge from the shadow of COVID-19, a critical analysis of the evidence base on both the assessment and mitigation of risk is vital for ENT departments worldwide. This article presents a systematic review of the literature examining articles which consider either the quantification of risk or strategies to mitigate risk specifically in the setting of rhinological surgery.
    Design: Systematic literature review.
    Results: The literature search yielded a total of 3406 returns with 24 articles meeting eligibility criteria. A narrative synthesis stratified results into two broad themes: (1) those which made an assessment as to the aerosolisation of droplets during sinus surgery, further sub-divided into work which considered macroscopically visible droplets and that which considered smaller particles; (2) and those studies which examined the mitigation of this risk.
    Conclusion: Studies considering the aerosolisation of both droplets and smaller particles suggest endonasal surgery carries significant risk. While results both highlight a range of innovative adjunctive strategies and support suction as an important intervention to reduce aerosolisation, appropriate use of personal protective equipment (PPE) should be considered mandatory for all healthcare professionals involved in rhinological surgery. Studies have demonstrated that close adherence to PPE use is effective in preventing COVID-19 infection.

    Abstract Asymmetrical flow field-flow fractionation (As-FlFFF) is a widely used technique for analyzing polydisperse nanoparticle and macromolecular samples. The programmed decay of cross flow rate is often employed. The interdependence of the cross flow rate through the membrane and the fluid flow along the channel length complicates the prediction of elution time and fractionating power. The theory for their calculation is presented. It is also confirmed for examples of exponential decay of cross flow rate with constant channel outlet flow rate that the residual sample polydispersity at the channel outlet is quite well approximated by the reciprocal of four times the fractionating power. Residual polydispersity is of importance when online MALS or DLS detection are used to extract quantitative information on particle size or molecular weight. The theory presented here provides a firm basis for the optimization of programmed flow conditions in As-FlFFF. Graphical abstract Channel outlet polydispersity remains significant following fractionation by As-FlFFF under conditions of programmed decay of cross flow rate.

    Abstract Background: The Joint Commission's National Patient Safety Goal (NPSG) for suicide prevention (NPSG.15.01.01) requires that accredited hospitals maintain policies/procedures for follow-up care at discharge for patients identified as at risk for suicide. The proportion of hospitals meeting these requirements through use of recommended discharge practices is unknown.
    Methods: This cross-sectional observational study explored the prevalence of suicide prevention activities among Joint Commission-accredited hospitals. A questionnaire was sent to 1,148 accredited hospitals. The authors calculated the percentage of hospitals reporting implementation of four recommended discharge practices for suicide prevention.
    Results: Of 1,148 hospitals, 346 (30.1%) responded. The majority (n = 212 [61.3%]) of hospitals had implemented formal safety planning, but few of those (n = 41 [19.3%]) included all key components of safety planning. Approximately a third of hospitals provided a warm handoff to outpatient care (n = 128 [37.0%)] or made follow-up contact with patients (n = 105 [30.3%]), and approximately a quarter (n = 97 [28.0%]) developed a plan for lethal means safety. Very few (n = 14 [4.0%]) hospitals met full criteria for implementing recommended suicide prevention activities at time of discharge.
    Conclusion: The study revealed a significant gap in implementation of recommended practices related to prevention of suicide postdischarge. Additional research is needed to identify factors contributing to this implementation gap.

    Abstract Background: Health care accreditation is a widely accepted mechanism for improving the quality of care and promoting patient safety. An integral dimension of health care quality is the patient experience of care. However, the influence of accreditation on the patient experience is unclear. The Home Health Consumer Assessment of Healthcare Providers and Systems (HHCAHPS) survey is the standard for collecting patient care experience data in the home health setting. The aim of this study was to examine the association of Joint Commission accreditation on patients' experience of care by comparing HHCAHPS ratings from Joint Commission-accredited and non-Joint Commission-accredited home health agencies (HHAs).
    Methods: This multiyear observational study used 2015-2019 HHCAHPS data obtained from the Centers for Medicare & Medicaid Services (CMS) website and Joint Commission databases. The data set included 1,454 (23.8%) Joint Commission-accredited and 4,643 (76.2%) non-Joint Commission-accredited HHAs. Dependent variables included three composite measures of care (Care of Patients, Provider-Patient Communications, and Specific Care Issues) and two global rating measures. Data were analyzed using a series of longitudinal random effects logistic regression models.
    Results: This study found no association between Joint Commission accreditation and the two global HHCAHPS measures, modest significant increases for Joint Commission-accredited HHAs in measure rates for the Care of Patients and Communication composite measures (p < 0.05), and a more significant increase for the Specific Care Issues composite measure related to medication safety and home safety (p < 0.001).
    Conclusions: These findings suggest that Joint Commission accreditation may be positively associated with some patient experience of care outcomes. This relationship was most pronounced when there was significant overlap between the focus of the accreditation standards and focus of the HHCAHPS items.

    Abstract Asian American (AA) families remain critically underrepresented in clinical trials for ADHD interventions. Little is known about AA families' engagement in and outcomes of behavioral treatment (BT). Comparing AA families to other minoritized (OM) families and White families, this study examined parental cognitions, treatment engagement, and child outcomes of BT for ADHD inattentive type (ADHD-I). Path analyses were conducted utilizing data from a randomized controlled trial of BT for ADHD-I (N = 199 children, ages 7-11). Racial/ethnic differences in pretreatment parental self-competence and treatment expectations were examined for AA (n = 29) compared to OM (n = 35) and White (n = 135) parents. Two additional path models were conducted to examine the relations among race/ethnicity, pretreatment parental cognitions, treatment engagement, and posttreatment child outcomes. Direct effects of race/ethnicity and parental cognitions on posttreatment child outcomes as well as their indirect effects via treatment engagement were estimated. At pretreatment, AA parents endorsed lower parental self-competence and treatment expectations compared to OM and White parents. At posttreatment, AA parents reported fewer improvements in ADHD symptoms than White parents and lower global psychosocial improvement than OM parents. For all parents, treatment expectations positively predicted parent- and observer-rated treatment engagement, which in turn predicted child global psychosocial improvement. Path analyses indicated that the relationship between treatment expectations and posttreatment child global improvement was fully mediated by treatment engagement. These findings suggest that treatment expectations impede AA parents' engagement and success in BT. Implications for cultural adaptations of BT to improve AA families' treatment experience are discussed.

    Abstract Asymmetrical flow field-flow fractionation (As-FlFFF) has become the most commonly used of the field-flow fractionation techniques. However, because of the interdependence of the channel flow and the cross flow through the accumulation wall, it is the most difficult of the techniques to optimize, particularly for programmed cross flow operation. For the analysis of polydisperse samples, the optimization should ideally be guided by the predicted fractionating power. Many experimentalists, however, neglect fractionating power and rely on light scattering detection simply to confirm apparent selectivity across the breadth of the eluted peak. The size information returned by the light scattering software is assumed to dispense with any reliance on theory to predict retention, and any departure of theoretical predictions from experimental observations is therefore considered of no importance. Separation depends on efficiency as well as selectivity, however, and efficiency can be a strong function of retention. The fractionation of a polydisperse sample by field-flow fractionation never provides a perfectly separated series of monodisperse fractions at the channel outlet. The outlet stream has some residual polydispersity, and it will be shown in this manuscript that the residual polydispersity is inversely related to the fractionating power. Due to the strong dependence of light scattering intensity and its angular distribution on the size of the scattering species, the outlet polydispersity must be minimized if reliable size data are to be obtained from the light scattering detector signal. It is shown that light scattering detection should be used with careful control of fractionating power to obtain optimized analysis of polydisperse samples. Part I is concerned with isocratic operation of As-FlFFF, and part II with programmed operation.

    Abstract The identification and characterization of the ubiquitin E-ligase complexes involved in specific proteins' degradation via the ubiquitin-proteasome system (UPS) can be challenging and require biochemical purification processes and in vitro reconstitution assays. Likewise, evaluating the effect of parallel phosphorylation and ubiquitination events occurring in vivo at dual phospho/ubiquitin-regulated motifs (called Phospho-Degrons or pDegrons) driving UPS degradation of the targeted protein has remained elusive. Indeed, the functional study of such E1-E2-E3 complexes acting on a protein-specific level requires previously or otherwise acquired knowledge of the nature of such degradation complex components. Furthermore, the molecular basis of the interaction between an E3 ligase and its pDegron binding motif on a target protein would require individually optimized in vitro kinase and ubiquitination assays. Here, we describe a novel enzymatically enhanced pull-down method to functionally streamline the discovery and functional validation of the ubiquitin E-ligase components interacting with a phospho-degron containing protein domain and/or sub-domain. The protocol combines key features of a protein kinase and ubiquitination in vitro assay by including them in a pull-down step exerted by a known or putative pDegron-tagged peptide using the cell extracts as a source of enzymatically active post-translational modification (PTM) modifying/binding native proteins. The same method allows studying specific stimuli or treatments towards the recruitment of the molecular degradation complex at the target protein's phospho-degron site, reflecting in vivo-initiated events further enhanced through the assay design. In order to take full advantage of the method over traditional protein-protein interaction methods, we propose to use this PTM-enhanced (PTMe) pull down both towards the degradation complex discovery/ID phase as well as for the functional pDegron recruitment validation phase, which is the one described in the present protocol both graphically and in a stepwise fashion for reproduceable results. Key features • Suitable to study UPS-regulated (a) cytosolic and/or nuclear proteins, (b) intracellular region of transmembrane proteins, and (c) protein sub-domains bearing a known/putative pDegron motif. • Requires a biotin-tagged recombinant version of the target protein and/or sub-domain. • Allows the qualitative and quantitative analysis of endogenous ubiquitin (Ub) E-ligases recruitment to a known or putative pDegron bearing protein/sub-domain. • Allows simultaneous testing of various treatments and/or conditions affecting the phosphorylative and/or ubiquitylation status of the studied pDegron bearing protein/sub-domain and the recruited factors.
