Patient involvement can affect cliniciansâ perspectives and practices of infection prevention and control: A âpost-qualitativeâ study using video-reflexive ethnography
© The Author(s) 2017. This study, set in a mixed, adult surgical ward of a metropolitan teaching hospital in Sydney, Australia, used a novel application of video-reflexive ethnography (VRE) to engage patients and clinicians in an exploration of the practical and relational complexities of patient involvement in infection prevention and control (IPC). This study included individual reflexive sessions with eight patients and six group reflexive sessions with 35 nurses. VRE usually involves participants reflecting on video footage of their own (and colleaguesâ) practices in group reflexive sessions. We extended the method here by presenting, to nurses, video clips of their clinical interactions with patients, in conjunction with footage of the patients themselves analyzing the videos of their own care, for infection risks.We found that this novel approach affected the nursesâ capacities to recognize, support, and enable patient involvement in IPC and to reflect on their own, sometimes inconsistent, IPC practices from patientsâ perspectives. As a âpost-qualitativeâ approach, VRE prioritizes participantsâ roles, contributions, and learning. Invoking affect as an explanatory lens, we theorize that a âsafe spaceâ was created for participants in our study to reflect on and reshape their assumptions, positionings, and practices
To follow a rule? On frontline cliniciansâ understandings and embodiments of hospital-acquired infection prevention and control rules
© The Author(s) 2018. This article reports on a study of cliniciansâ responses to footage of their enactments of infection prevention and control. The studyâs approach was to elicit cliniciansâ reflections on and clarifications about the connections among infection control activities and infection control rules, taking into account their awareness, interpretation and in situ application of those rules. The findings of the study are that clinicians responded to footage of their own infection prevention and control practices by articulating previously unheeded tensions and constraints including infection control rules that were incomplete, undergoing change, and conflicting; material obstructions limiting infection control efforts; and habituated and divergent rule enactments and rule interpretations that were problematic but disregarded. The reflexive process is shown to elicit cliniciansâ learning about these complexities as they affect the accomplishment of effective infection control. The process is further shown to strengthen cliniciansâ appreciation of infection control as necessitating deliberation to decide what are locally appropriate standards, interpretations, assumptions, habituations and enactments of infection control. The article concludes that cliniciansâ âpractical wisdomâ is unlikely to reach its full potential without video-assisted scrutiny of and deliberation about in situ clinical work. This enables clinicians to anchor their in situ enactments, reasonings and interpretations to local agreements about the intent, applicability, limits and practical enactment of rules
A topological Dirac insulator in a quantum spin Hall phase : Experimental observation of first strong topological insulator
When electrons are subject to a large external magnetic field, the
conventional charge quantum Hall effect \cite{Klitzing,Tsui} dictates that an
electronic excitation gap is generated in the sample bulk, but metallic
conduction is permitted at the boundary. Recent theoretical models suggest that
certain bulk insulators with large spin-orbit interactions may also naturally
support conducting topological boundary states in the extreme quantum limit,
which opens up the possibility for studying unusual quantum Hall-like phenomena
in zero external magnetic field. Bulk BiSb single crystals are
expected to be prime candidates for one such unusual Hall phase of matter known
as the topological insulator. The hallmark of a topological insulator is the
existence of metallic surface states that are higher dimensional analogues of
the edge states that characterize a spin Hall insulator. In addition to its
interesting boundary states, the bulk of BiSb is predicted to
exhibit three-dimensional Dirac particles, another topic of heightened current
interest. Here, using incident-photon-energy-modulated (IPEM-ARPES), we report
the first direct observation of massive Dirac particles in the bulk of
BiSb, locate the Kramers' points at the sample's boundary and
provide a comprehensive mapping of the topological Dirac insulator's gapless
surface modes. These findings taken together suggest that the observed surface
state on the boundary of the bulk insulator is a realization of the much sought
exotic "topological metal". They also suggest that this material has potential
application in developing next-generation quantum computing devices.Comment: 16 pages, 3 Figures. Submitted to NATURE on 25th November(2007
Creating spaces in intensive care for safe communication : a video-reflexive ethnographic study
The built environment in acute care settings is a new focus in patient safety research, with few studies focusing primarily on the design of ward environments and the location and choice of material objects such as light fittings and hand-washing basins
Enablers of, and barriers to, optimal glove and mask use for routine care in the emergency department: an ethnographic study of Australian clinicians
© 2019 College of Emergency Nursing Australasia Background: The risk of healthcare-acquired infection increases during outbreaks of novel infectious diseases. Emergency department (ED) clinicians are at high risk of exposure to both these and common communicable diseases. Personal protective equipment (PPE) is recommended to protect clinicians from acquiring, or becoming vectors of, infection, yet compliance is typically sub-optimal. Little is known about factors that influence use of PPEâspecifically gloves and masksâduring routine care in the ED. Methods: This was an ethnographic study, incorporating documentation review, field observations and interviews. The theoretical domains framework (TDF) was used to aid thematic analysis and identify relevant enablers of and barriers to optimal PPE use. Results: Thirty-one behavioural themes were identified that influenced participantsâ use of masks and gloves. There were significant differences, namely: more reported enablers of glove use vs more barriers to mask use. Reasons included more positive unit culture towards glove use, and lower perception of risk via facial contamination. Conclusion: Emerging infectious diseases, spread (among other routes) by respiratory droplets, have caused global outbreaks. Emergency clinicians should ensure that, as with gloves, the use of masks is incorporated into routine cares where appropriate. Further research which examines items of PPE independently is warranted
Multiple Accountabilities In Incident Reporting And Management
In this article, we examine the current and increasing emphasis on accountability and patient safety in health care, focusing on practices of incident reporting and management in New South Wales, Australia. We describe the frames of accountability assoc
Beyond hand hygiene: A qualitative study of the everyday work of preventing cross-contamination on Hospital wards
© 2017 BMJ Publishing Group. All rights reserved. Background: Hospital-acquired infections are the most common adverse event for inpatients worldwide. Efforts to prevent microbial crosscontamination currently focus on hand hygiene and use of personal protective equipment (PPE), with variable success. Better understanding is needed of infection prevention and control (IPC) in routine clinical practice. Methods: We report on an interventionist videoreflexive ethnography study that explored how healthcare workers performed IPC in three wards in two hospitals in New South Wales, Australia: an intensive care unit and two general surgical wards. We conducted 46 semistructured interviews, 24 weeks of fieldwork (observation and videoing) and 22 reflexive sessions with a total of 177 participants (medical, nursing, allied health, clerical and cleaning staff, and medical and nursing students). We performed a postintervention analysis, using a modified grounded theory approach, to account for the range of IPC practices identified by participants. Results: We found that healthcare workers' routine IPC work goes beyond hand hygiene and PPE. It also involves, for instance, the distribution of team members during rounds, the choreography of performing aseptic procedures and moving 'from clean to dirty' when examining patients. We account for these practices as the logistical work of moving bodies and objects across boundaries, especially from contaminated to clean/vulnerable spaces, while restricting the movement of micro-organisms through cleaning, applying barriers and buffers, and trajectory planning. Conclusions: Attention to the logistics of moving people and objects around healthcare spaces, especially into vulnerable areas, allows for a more comprehensive approach to IPC through better contextualisation of hand hygiene and PPE protocols, better identification of transmission risks, and the design and promotion of a wider range of preventive strategies and solutions
Genotoxicity and acute and subchronic toxicity studies of a standardized methanolic extract of Ficus deltoidea leaves
OBJECTIVE: Ficus deltoidea leaves have been used in traditional medicine in Southeast Asia to treat diabetes, inflammation, diarrhea, and infections. The present study was conducted to assess the genotoxicity and acute and subchronic toxicity of a standardized methanol extract of F. deltoidea leaves. METHODS: Sprague Dawley rats were orally treated with five different single doses of the extract and screened for signs of toxicity for two weeks after administration. In the subchronic study, three different doses of the extract were administered for 28 days. Mortality, clinical signs, body weight changes, hematological and biochemical parameters, gross findings, organ weights, and histological parameters were monitored during the study. Genotoxicity was assessed using the Ames test with the TA98 and TA100 Salmonella typhimurium strains. Phytochemical standardization was performed using a colorimeter and high-performance liquid chromatography. Heavy metal detection was performed using an atomic absorption spectrometer. RESULTS: The acute toxicity study showed that the LD(50) of the extract was greater than 5000 mg/kg. In the subchronic toxicity study, there were no significant adverse effects on food consumption, body weight, organ weights, mortality, clinical chemistry, hematology, gross pathology, or histopathology. However, a dose-dependent increase in the serum urea level was observed. The Ames test revealed that the extract did not have any potential to induce gene mutations in S. typhimurium, either in the presence or absence of S9 activation. Phytochemical analysis of the extract revealed high contents of phenolics, flavonoids, and tannins. High-performance liquid chromatography analysis revealed high levels of vitexin and isovitexin in the extract, and the levels of heavy metals were below the toxic levels. CONCLUSION: The no-observed adverse effect level of F. deltoidea in rats was determined to be 2500 mg/kg
Involving patients in understanding hospital infection control using visual methods
© 2015 John Wiley & Sons Ltd. Aims and Objectives: This paper explores patients' perspectives on infection prevention and control. Background: Healthcare-associated infections are the most frequent adverse event experienced by patients. Reduction strategies have predominantly addressed front-line clinicians' practices; patients' roles have been less explored. Design: Video-reflexive ethnography. Methods: Fieldwork undertaken at a large metropolitan hospital in Australia involved 300 hours of ethnographic observations, including 11 hours of video footage. This paper focuses on eight occasions, where video footage was shown back to patients in one-on-one reflexive sessions. Findings: Viewing and discussing video footage of clinical care enabled patients to become articulate about infection risks, and to identify their own roles in reducing transmission. Barriers to detailed understandings of preventative practices and their roles included lack of conversation between patients and clinicians about infection prevention and control, and being ignored or contradicted when challenging perceived suboptimal practice. It became evident that to compensate for clinicians' lack of engagement around infection control, participants had developed a range of strategies, of variable effectiveness, to protect themselves and others. Finally, the reflexive process engendered closer scrutiny and a more critical attitude to infection control that increased patients' sense of agency. Conclusion: This study found that patients actively contribute to their own safety. Their success, however, depends on the quality of patient-provider relationships and conversations. Rather than treating patients as passive recipients of infection control practices, clinicians can support and engage with patients' contributions towards achieving safer care. Relevance to clinical practice: This study suggests that if clinicians seek to reduce infection rates, they must start to consider patients as active contributors to infection control. Clinicians can engage patients in conversations about practices and pay attention to patient feedback about infection risk. This will broaden clinicians' understandings of infection control risks and behaviours, and assist them to support appropriate patient self-care behaviour
