Preventative measures taken against hypothermia in selected Durban hospitals' emergency centres and operating theatres.

ABSTRACT: Introduction:Hypothermia is common in emergency general surgical patients. It is known to be associated with major complications in multiple organ systems. It is also easily preventable with the use of safe and cost-effective equipment. However, by observation, it appears that this equipment is used too infrequently thus resulting in unnecessary harm to patients. Methods:This descriptive, observational, cross-sectional study was conducted in two arms to evaluate both emergency centres and operating theatres in the major state hospitals in Durban. It was conducted as an audit as well as a questionnaire-based study, to ascertain the availability of equipment used to prevent hypothermia and also how appropriately the equipment was being used. Results:There was good availability of equipment in both the operating theatres and the emergency centres. However it was being used very poorly, particularly in emergency centres (41% of responses deemed not beneficial to patients versus 29% from operating theatres; 39% of answers beneficial versus 54% from operating theatres). Institutions with hypothermia-prevention protocols scored significantly better than those without a protocol (59% versus 25% beneficial; p = 0.01). Conclusion:In the field of hypothermia prevention, there was sufficient equipment to result in optimal patient care. However there appears to be a lack of knowledge amongst health care providers, resulting in suboptimal use of this equipment. Protocolised management may provide a solution to this problem and improve patient outcomes.

Project description:AimNetworkZ is a simulation-based multidisciplinary team-training programme designed to enhance patient safety by improving communication and teamwork in operating theatres (OTs). In partnership with the Accident Compensation Corporation, its implementation across New Zealand (NZ) began in 2017. Our aim was to explore the experiences of staff - including the challenges they faced - in implementing NetworkZ in NZ hospitals, so that we could improve the processes necessary for subsequent implementation.MethodWe interviewed staff from five hospitals involved in the initial implementation of NetworkZ, using the Organising for Quality model as the framework for analysis. This model describes embedding successful quality improvement as a process of overcoming six universal challenges: structure, infrastructure, politics, culture, motivation and learning.ResultsThirty-one people participated. Structural support within the hospital was considered essential to maintain staff enthusiasm, momentum and to embed the programme. The multidisciplinary, simulation-based approach to team training was deemed a fundamental infrastructure for learning, with participants especially valuing the realistic in situ simulations and educational support. Participants reported positive changes to the OT culture as a result of NetworkZ and this realisation motivated its implementation. In sites with good structural support, NetworkZ implementation proceeded quickly and participants reported rapid cultural change towards improved teamwork and communication in their OTs.ConclusionImplementation challenges exist and strategies to overcome these are informing future implementation of NetworkZ. Embedding the programme as business as usual across a nation requires significant and sustained support at all levels. However, the potential gains in patient safety and workplace culture from widespread multidisciplinary team training are substantial. Trial registration number ACTRN12617000017325.

Project description:Since March of 2020, over 210 million SARS-CoV-2 cases have been reported and roughly five billion doses of a SARS-CoV-2 vaccine have been delivered. The rise of the more infectious delta variant has recently indicated the value of reinstating previously relaxed non-pharmacological and test-driven preventative measures. These efforts have been met with resistance, due, in part, to a lack of site-specific quantitative evidence which can justify their value. As vaccination rates continue to increase, a gap in knowledge exists regarding appropriate thresholds for escalation and de-escalation of COVID-19 preventative measures. We conducted a series of simulation experiments, trialing the spread of SARS-CoV-2 virus in a hypothesized working environment that is subject to COVID-19 infections from the surrounding community. We established cohorts of individuals who would, in simulation, work together for a set period of time. With these cohorts, we tested the rates of workplace and community acquired infections based on applied isolation strategies, community infection rates (CIR), scales of testing, non-pharmaceutical interventions, variant predominanceâ€™s and testing strategies, vaccination coverages, and vaccination efficacies of the members included. Permuting through each combination of these variables, we estimated expected case counts for 33,462 unique workplace scenarios. When the CIR is 5 new confirmed cases per 100,000 or fewer, and at 50% of the workforce is vaccinated with a 95% efficacious vaccine, then testing daily with an antigen-based or PCR based test in only unvaccinated workers will result in less than one infection through 4,800 person weeks. When the community infection rate per 100,000 persons is less than or equal to 60, and the vaccination coverage of the workforce is 100% with 95% vaccine efficacy then no masking or routine testing + isolation strategies are needed to prevent workplace acquired infections regardless of variant predominance. Identifying and isolating workers with antigen-based SARS-CoV-2 testing methods results in the same or fewer workplace acquired infections than testing with polymerase chain reaction (PCR) methods. Specific scenarios exist in which preventative measures taken to prevent SARS-CoV-2 spread, including masking, and testing plus isolation strategies can safely be relaxed. Further, efficacious testing with quarantine strategies exist for implementation in only unvaccinated cohorts in a workplace. Due to shorter turnaround time, antigen-based testing with lower sensitivity is more effective than PCR testing with higher sensitivities in comparable testing strategies. The general reference interactive heatmap we provide can be used for site specific, immediate, parameter-based case count predictions to inform appropriate institutional policy making.

Project description:IntroductionFace coverings and distancing as preventative measures against the spread of the Coronavirus disease 2019 may impact communication in several ways that may disproportionately affect people with hearing loss. A scoping review was conducted to examine existing literature on the impact of preventative measures on communication and to characterize the clinical implications.MethodA systematic search of three electronic databases (Scopus, PubMed, CINAHL) was conducted yielding 2,158 articles. After removing duplicates and screening to determine inclusion eligibility, key data were extracted from the 50 included articles. Findings are reported following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Extension for Scoping Reviews, including the PRISMA-ScR checklist.ResultsStudies fell into three categories: Studies addressing the impacts of personal protective equipment (PPE) and/or distancing on communication in healthcare contexts (n = 20); studies examining the impact of preventative measures on communication in everyday life (n = 13), and studies measuring the impact of face coverings on speech using acoustic and/or behavioral measures (n = 29). The review revealed that masks disrupt verbal and non-verbal communication, as well as emotional and social wellbeing and they impact people with hearing loss more than those without. These findings are presumably because opaque masks attenuate sound at frequencies above 1 kHz, and conceal the mouth and lips making lipreading impossible, and limit visibility of facial expressions. While surgical masks cause relatively little sound attenuation, transparent masks and face shields are highly attenuating. However, they are preferred by people with hearing loss because they give access to visual cues.ConclusionFace coverings and social distancing has detrimental effects that extend well beyond verbal and non-verbal communication, by affecting wellbeing and quality of life. As these measures will likely be part of everyday life for the foreseeable future, we propose that it is necessary to support effective communication, especially in healthcare settings and for people with hearing loss.
