Promoting health equity with HBCUs: Breaking away from structural racism.

BACKGROUND: The United States continues to be plagued with pervasive health disparities. Leading health and professional organizations acknowledge structural racism as a contributing factor for the lack of a racially diverse nursing workforce particularly those serving in leadership roles which could help to mitigate health disparities among historically stigmatized populations. PURPOSE: Purpose Lack of funding for Historically Black Colleges and Universities (HBCUs) and lack of meaningful partnerships, stymie efforts that can be made by nursing programs at HBCUs. DISCUSSION: Discussion This position paper examines collaborative actions that can address upstream factors that perpetuate healthcare disparities through deep engagement between the policymakers, professional associations, industry, and educational institutions. METHODS: Faculty representing HBCU's and predominately White institutions, professional organizations, and staff met via videoconference to refine the focus of the paper, determine topic areas for writing teams, and refine details which occurred during weekly meetings. CONCLUSION: To disengage from structural racism, three critical recommendations are amplified with associated examples.

Health care workers' experiences of video-based monitoring of hand hygiene behaviors: a qualitative study.

BACKGROUND: Hand hygiene is key to preventing health care-associated infections. Human observation is the gold standard for measuring compliance, but its utility is increasingly being questioned with calls for the use of video monitoring approaches. The utility of video-based systems to measure compliance according to the WHO 5 moments is largely unexamined, as is its acceptability amongst health care workers (HCW) and patients. This study examined HCW acceptability of video monitoring for hand hygiene auditing. METHODS: Following trial of a video monitoring system (reported elsewhere), 5 participating HCW attended 2 in-depth group interviews where they reviewed the footage and explored responses to the approach. Transcripts were analyzed using thematic analysis. RESULTS: Four themes were identified: 1) Fears; 2) Concerns for patients; 3) Changes to feedback; and 4) Behavioral responses to the cameras. HCWs expressed fears of punitive consequences, data security, and confidentiality. For patients, HCWs raised issues regarding invasion of privacy, ethics, and consent. HCWs suggested that video systems may result in less immediate feedback but also identified potential to use the footage for feedback. They also suggested that the Hawthorne Effect was less potent with video systems than human observation. CONCLUSIONS: The acceptability of video monitoring systems for hand hygiene compliance is complex and has the potential to complicate practical implementation. Additionally, exploration of the acceptability to patients is warranted. CHECKLIST: COREQ.

Exploring healthcare workers' perspectives of video feedback for training in the use of powered air purifying respirators (PAPR) at the onset of the COVID-19 pandemic.

BACKGROUND: With the advent of COVID-19, many healthcare workers (HWs) in Australia requested access to powered air purifying respirators (PAPR) for improved respiratory protection, comfort and visibility. The urgency of the response at our hospital required rapid deployment of innovative training to ensure the safe use of PAPRs, in particular, a video-feedback training option to prepare HWs for PAPR competency. AIM: To explore the feasibility, acceptability, and utility of video-feedback in PAPR training and competency assessment. METHODS: Semi-structured interviews were conducted with 12 HWs, including clinicians from Intensive Care, Anaesthetics and Respiratory Medicine, at a large teaching hospital in Australia. FINDINGS: Participants believed that the use of video-feedback in PAPR training was feasible, acceptable and useful. They described a variety of benefits to learning and retention, from a variety of ways in which they engaged with the personal video-feedback. Participants also described the impact of reviewing personalised practice footage, compared to generic footage of an ideal performance. CONCLUSION: By conceptualising video-feedback using a pedagogical approach, this study contributes to knowledge around optimising methods for training HWs in PPE use, particularly when introducing a new and complex PPE device during an infectious disease outbreak.

Taking the Temperature of Distance Learners: Does University Climate Influence Perceptions of Belonging in a Distance Education Environment?

AIM: This study aimed to gain an understanding of how students' perceptions of belonging are impacted by their observations of the cultural/racial climate and diversity and inclusion in a distance education environment. BACKGROUND: Studies have evaluated students' perceptions of belonging and racial climate in a physical environment; there is a gap in understanding those perceptions within a distance education environment. METHOD: In 2019, an online survey was administered to distance learning students from four academic programs at a national university that provides education services in all 50 states. RESULTS: Results of a multiple linear regression analysis showed that students' perceptions of university inclusion and diversity efforts, experiences related to language barriers, and advisors played a significant role in students' perceptions of belonging, F(4, 205) = 52.96, p < .000, with an R2 of .51. CONCLUSION: Supporting an equitable distance learning environment should be a paramount objective for universities.

Methodological and technical considerations for video-based auditing of hand hygiene compliance in clinical practice: an exploratory study.

BACKGROUND: Direct observation is the gold standard method for measuring hand hygiene compliance but its utility is increasingly being questioned. Various alternative electronic methods have been proposed, yet there is a paucity of research examining the use of these according to the World Health Organization's (WHO) '5 Moments for Hand Hygiene'. As a part of the process of developing a video-based monitoring system (VMS) capable of measuring hand hygiene compliance against the 5 moments criteria this paper reports methodological and technical issues that might arise from the use of a VMS for auditing in clinical practice. METHODS: In-depth semi-structured interviews were conducted with 27 Australian content experts in hand hygiene auditing and infection prevention to explore their responses to proposed VMS auditing approaches. Transcripts were analyzed using thematic and content analysis. RESULTS: Technical and methodological considerations for the use of VMS were interrelated and included concerns surrounding privacy, footage security, fears of surveillance and the potential for medico-legal consequences. Additionally, possible detrimental impacts on healthcare worker (HCW) -patient relationships, issues of cost versus benefits, HCW and patient safety and changes to feedback were also identified. CONCLUSIONS: The primary methodological and technical issues to overcome in order to implement VMS for hand hygiene auditing in clinical practice, centered upon issues of acceptability to patients and health professionals, privacy, consent and liability.

Fulminant Bacillus cereus food poisoning with fatal multi-organ failure.

This case represents a rare fulminant course of fried-rice associated food poisoning in an immunocompetent person due to pre-formed exotoxin produced by Bacillus cereus, with severe manifestations of sepsis, including multi-organ (hepatic, renal, cardiac, respiratory and neurological) failure, shock, metabolic acidosis, rhabdomyolysis and coagulopathy. Despite maximal supportive measures (continuous renal replacement therapy, plasmapheresis, N-acetylcysteine infusion and blood products, and broad-spectrum antimicrobials) and input from a multidisciplinary team (consisting of infectious diseases, intensive care, gastroenterology, surgery, toxicology, immunology and haematology), mortality resulted. This case is the first to use whole genome sequencing techniques to confirm the toxigenic potential of B. cereus It has important implications for food preparation and storage, particularly given its occurrence in home isolation during the COVID-19 pandemic.

Effect of Vancomycin or Daptomycin With vs Without an Antistaphylococcal ß-Lactam on Mortality, Bacteremia, Relapse, or Treatment Failure in Patients With MRSA Bacteremia: A Randomized Clinical Trial.

Importance: Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is associated with mortality of more than 20%. Combining standard therapy with a ß-lactam antibiotic has been associated with reduced mortality, although adequately powered randomized clinical trials of this intervention have not been conducted. Objective: To determine whether combining an antistaphylococcal ß-lactam with standard therapy is more effective than standard therapy alone in patients with MRSA bacteremia. Design, Setting, and Participants: Open-label, randomized clinical trial conducted at 27 hospital sites in 4 countries from August 2015 to July 2018 among 352 hospitalized adults with MRSA bacteremia. Follow-up was complete on October 23, 2018. Interventions: Participants were randomized to standard therapy (intravenous vancomycin or daptomycin) plus an antistaphylococcal ß-lactam (intravenous flucloxacillin, cloxacillin, or cefazolin) (n = 174) or standard therapy alone (n = 178). Total duration of therapy was determined by treating clinicians and the ß-lactam was administered for 7 days. Main Outcomes and Measures: The primary end point was a 90-day composite of mortality, persistent bacteremia at day 5, microbiological relapse, and microbiological treatment failure. Secondary outcomes included mortality at days 14, 42, and 90; persistent bacteremia at days 2 and 5; acute kidney injury (AKI); microbiological relapse; microbiological treatment failure; and duration of intravenous antibiotics. Results: The data and safety monitoring board recommended early termination of the study prior to enrollment of 440 patients because of safety. Among 352 patients randomized (mean age, 62.2 [SD, 17.7] years; 121 women [34.4%]), 345 (98%) completed the trial. The primary end point was met by 59 (35%) with combination therapy and 68 (39%) with standard therapy (absolute difference, -4.2%; 95% CI, -14.3% to 6.0%). Seven of 9 prespecified secondary end points showed no significant difference. For the combination therapy vs standard therapy groups, all-cause 90-day mortality occurred in 35 (21%) vs 28 (16%) (difference, 4.5%; 95% CI, -3.7% to 12.7%); persistent bacteremia at day 5 was observed in 19 of 166 (11%) vs 35 of 172 (20%) (difference, -8.9%; 95% CI, -16.6% to -1.2%); and, excluding patients receiving dialysis at baseline, AKI occurred in 34 of 145 (23%) vs 9 of 145 (6%) (difference, 17.2%; 95% CI, 9.3%-25.2%). Conclusions and Relevance: Among patients with MRSA bacteremia, addition of an antistaphylococcal ß-lactam to standard antibiotic therapy with vancomycin or daptomycin did not result in significant improvement in the primary composite end point of mortality, persistent bacteremia, relapse, or treatment failure. Early trial termination for safety concerns and the possibility that the study was underpowered to detect clinically important differences in favor of the intervention should be considered when interpreting the findings.

Blood cultures and bacteraemia in an Australian emergency department: Evaluating a predictive rule to guide collection and their clinical impact.

OBJECTIVE: The objective of the present study is to determine whether a predictive rule could safely reduce the number of negative blood cultures collected in an Australian ED and to assess the clinical impact of positive results from blood cultures taken in the ED. METHODS: All positive blood cultures taken in the ED at a single facility were retrospectively identified for the calendar year 2012. Clinically significant bacteraemia episodes were assessed against a predictive rule using major and minor clinical and laboratory criteria gathered from medical records and pathology databases, and compared with a randomly generated sample of ED patient episode with negative blood cultures. The ED and final diagnoses and blood culture impact on clinical management were also collected. RESULTS: The predictive rule has a high sensitivity (98.8%) and modest specificity (48.7%), and if applied stringently would have prevented almost half of all blood cultures in our ED but missed two positives. Blood cultures altered the clinical management of 94.3% bacteraemic patients, representing 3.4% of all ED patients with blood cultures performed. High discordance (54%) between ED diagnosis and discharge diagnosis of bacteraemic patients was noted. CONCLUSIONS: Bacteraemia detected in the ED alters subsequent patient management. The predictive rule can be safely applied in the ED to determine need for blood culture collection. Blood cultures should not be omitted in the ED based entirely on preliminary diagnosis given the high discordance seen between ED and discharge diagnosis.

Combination of Vancomycin and ß-Lactam Therapy for Methicillin-Resistant Staphylococcus aureus Bacteremia: A Pilot Multicenter Randomized Controlled Trial.

BACKGROUND: In vitro laboratory and animal studies demonstrate a synergistic role for the combination of vancomycin and antistaphylococcal ß-lactams for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. Prospective clinical data are lacking. METHODS: In this open-label, multicenter, clinical trial, adults with MRSA bacteremia received vancomycin 1.5 g intravenously twice daily and were randomly assigned (1:1) to receive intravenous flucloxacillin 2 g every 6 hours for 7 days (combination group) or no additional therapy (standard therapy group). Participants were stratified by hospital and randomized in permuted blocks of variable size. Randomization codes were kept in sealed, sequentially numbered, opaque envelopes. The primary outcome was the duration of MRSA bacteremia in days. RESULTS: We randomly assigned 60 patients to receive vancomycin (n = 29), or vancomycin plus flucloxacillin (n = 31). The mean duration of bacteremia was 3.00 days in the standard therapy group and 1.94 days in the combination group. According to a negative binomial model, the mean time to resolution of bacteremia in the combination group was 65% (95% confidence interval, 41%-102%; P = .06) that in the standard therapy group. There was no difference in the secondary end points of 28- and 90-day mortality, metastatic infection, nephrotoxicity, or hepatotoxicity. CONCLUSIONS: Combining an antistaphylococcal ß-lactam with vancomycin may shorten the duration of MRSA bacteremia. Further trials with a larger sample size and objective clinically relevant end points are warranted. Australian New Zealand Clinical Trials Registry: ACTRN12610000940077 (www.anzctr.org.au).

Human rhinovirus C in adult haematopoietic stem cell transplant recipients with respiratory illness.

BACKGROUND: A previously unidentified species of human rhinovirus, HRV-C, was described in 2006 in association with lower respiratory tract infection (LRTI). Features of infection in immunosuppressed adults are poorly characterised. OBJECTIVES: This study aims to determine the epidemiology of HRV-C in haematopoietic stem cell transplant (HSCT) recipients in a single centre. STUDY DESIGN: A prospective cohort study of all HSCT recipients admitted to Westmead Hospital, Westmead, Australia from 1 July 2005 to 30 September 2007 was undertaken. Nose/throat samples were collected from all patients at the time of admission and patients developing pre-defined symptoms and/or signs of respiratory infection during the admission. Samples were processed and tested for rhinoviruses and 14 other respiratory viruses using nucleic acid-based methods, immunofluorescence and culture. HRV genotyping was performed by sequencing a region of the rhinovirus 5' untranslated region (UTR). Clinical data on each episode were collected prospectively. RESULTS: HRVs were identified in 24 episodes: 8% of 299 episodes of clinically- defined respiratory infections and 39% of 61 episodes in which respiratory viruses were detected. HRV-C was most frequent (HRV-C: nine, HRV-A: eight and HRV-B: two). Seven episodes of HRV-C, five with pneumonia, occurred within 100 days of HSCT. Co-pathogens were frequent. CONCLUSIONS: The newly described HRV-C was the most common rhinovirus group detected in HSCT recipients with respiratory infection, with co-pathogens being frequent. Further research is required to understand the activity and pathogenicity of this virus in HSCT recipients.

Oseltamivir resistance in adult oncology and hematology patients infected with pandemic (H1N1) 2009 virus, Australia.

We describe laboratory-confirmed influenza A pandemic (H1N1) 2009 in 17 hospitalized recipients of a hematopoietic stem cell transplant (HSCT) (8 allogeneic) and in 15 patients with malignancy treated at 6 Australian tertiary centers during winter 2009. Ten (31.3%) patients were admitted to intensive care, and 9 of them were HSCT recipients. All recipients of allogeneic HSCT with infection <100 days posttransplantation or severe graft-versus-host disease were admitted to an intensive care unit. In-hospital mortality rate was 21.9% (7/32). The H275Y neuraminidase mutation, which confers oseltamivir resistance developed in 4 of 7 patients with PCR positive for influenza after > or = 4 days of oseltamivir therapy. Three of these 4 patients were critically ill. Oseltamivir resistance in 4 (13.3%) of 30 patients who were administered oseltamivir highlights the need for ongoing surveillance of such resistance and further research on optimal antiviral therapy in the immunocompromised.

Whole-genome characterization and genotyping of global WU polyomavirus strains.

Exploration of the genetic diversity of WU polyomavirus (WUV) has been limited in terms of the specimen numbers and particularly the sizes of the genomic fragments analyzed. Using whole-genome sequencing of 48 WUV strains collected in four continents over a 5-year period and 16 publicly available whole-genome sequences, we identified three main WUV clades and five subtypes, provisionally termed Ia, Ib, Ic, II, IIIa, and IIIb. Overall nucleotide variation was low (0 to 1.2%). The discriminatory power of the previous VP2 fragment typing method was found to be limited, and a new, larger genotyping region within the VP2/1 interface was proposed.

Parainfluenza virus type 3 pneumonia in bone marrow transplant recipients: multiple small nodules in high- resolution lung computed tomography scans provide a radiological clue to diagnosis.

We report the findings of high-resolution chest computed tomography of 6 hematopoietic stem cell transplant recipients with parainfluenza virus type 3 pneumonia who were not infected with any other pathogens. All patients had multiple small nodules (diameter, !5 mm) without cavitation ina peribronchial distribution. Changes preceded microbiological diagnosis in 4 of 6 cases.

A new focus of Rickettsia honei spotted fever in South Australia.

We recently diagnosed rickettsial spotted fever in four patients from the south-eastern coastal region of South Australia near Adelaide, an area not known to be endemic for this infection. All infections were acquired within the geographic range of Aponomma hydrosauri, the tick vector of Rickettsia honei. Infection by R. honei was confirmed in two patients. This extension of the known geographic range of R. honei infection may be explained, in part, by alterations in host-parasite ecology.
