Safety Climate And Healthcare Worker Injury Rates

BACKGROUND: Safety climates that support safety-related behavior are associated with a fewer work-related injuries, and prior research in industry suggests that safety knowledge and motivation are strongly related to safety performance behaviors; this relationship is not well studied in healthcare settings. METHODS: We performed analyses of survey results from a Veterans Health Administration (VHA) Safety Barometer employee perception survey, conducted among VHA employees in 2012. The employee perception survey assessed six safety program categories, including management participation, supervisor participation, employee participation, safety support activities, safety support climate, and organizational climate. We examined the impact of safety climate from the survey results on VHA employee injury and illness rates. RESULTS: Of the six safety program categories, VHA work-related injury and illness rates were significantly and inversely related to employee perception of supervisor participation and safety support climate. Among VHA facilities in The VA New England Healthcare System, work-related injury rate was significantly and inversely related to overall employee perception of safety climate, and all six safety program categories, including employee perception of employee participation, management participation, organizational climate, supervisor participation, safety support activities, and safety support climate. CONCLUSIONS: Employee perceptions of superior safety climates in VHA facilities are associated with lower work-related injury and illness rates. Of the safety culture determinants analyzed, VHA supervisor participation and safety support climate were identified as the elements most strongly associated with work-related injury rates. Future implications may include improving supervisor participation and safety support climate in the VA healthcare system to reduce employee injury rates

Psychiatric problems in the primary health care context: a study in the Border-Kei area

A clinic survey was undertaken to investigate the nature of psychiatric problems experienced by the primary health care (PHC) patient population in the Bisho-King William's Town area of the Eastern Cape Region. The study took as its point of departure research findings which attest to the high rate of psychiatric distress amongst this population group in different parts of the world and ohservations regarding the form of presentation in terms of physical complaints. Hypotheses posited relationships between psychiatric problems experienced by patients attending PHC clinics in the study area and four types of variables, namely; somatic complaints, socio-demographic characteristics, patterns of health service utilisation and patient satisfaction with health services. Using a quasi-experimental descriptive approach, a two-stage screening procedure sorted the patient sample into three groups on the basis of the degree of psychiatric symptomatology experienced. The triangulation of the results of between-groups analyses with case materials recorded during psychiatric interviewing provided for an ethnographic account of the cultural experience of distress in the study area. The screening process used standard instruments, the Self-Reporting Questionnaire (SRQ) in the first stage and the Present State Examination (PSE) in the second stage. A pilot study was conducted prior to the fieldwork for the main study. Using the SRQ, thirteen psychiatric paticnts and 31 general PHC patients were sampled for the pilot study and 148 PHC patients were sampled for the main study. Using the PSE, 11 and 57 PSE interviews were conducted in the pilot and main studies respectively. Between-groups analyses used chi-square and F-statistics to investigate possible associations with identified patient correlates (P<0.5). These were socio-demographic, utilisation and satisfaction variables, measured by a separate face-valid self-response instrument compiled for the purposes of this study. Psychiatric symptomatology was found to be statistically significantly related to age, marital status and educational level. Further, patients experiencing more psychiatric symptomatology reported significantly more illnesses requiring treatment, longer consultation periods and a greater number of sick bed days. No statistically significant relationships were found between psychiatric symptomatology and number of children, number of failures at school, amount of treatment utilised, number of consultations, or patient satisfaction with services. Descriptive analyses of symptom and syndrome profiles found certain somatic complaints to be particularly prevalent amongst the patient sample. These include headaches and various tension pains, decreased energy levels and digestive problems. Qualitative analysis of interview data found that many somatic and psychiatric problems experienced constitute culturally defined and meaningful experiences, especially 'umbilini' (or nerves), 'ufufunyana' (a possession state), and accusations of witchcraft. Interpretation of complaints from the local traditional healing perspective, revealed a more complex mode of communication between patients and the health delivery system than may be accounted for in terms of a simple biomedical model. The interpretive analysis in the study showed that some forms of presentation incorporating somatic symptoms, such as 'nerves' may he viewed as help seeking behaviour of the socially unempowered. Implications of the results are discussed in relation to the need for improved identification and management of psychiatric distress at PHC level facilitated by a better developed referral network and closer interaction between biomedical and anthropological perspectives

Incorporating Digital Learning Tools in Conjunction with Air Traffic Control Simulation

Learning and applying complex information at a fast rate can be challenging for students within an air traffic control - training program. Incorporating digital learning tools into an air traffic control training programs may increase student learning and success rates. Swivl is a digital learning capture tool designed to enhance student learning by allowing students to refer back to their individual classroom lab training session videos via an online portal. Embry Riddle’s air traffic program has started using Swivl in two separate ATC courses in order to determine if it is a viable solution to increase learning. During our research, we have come to the conclusion that Swivl is most useful in the air traffic control tower simulator, and has shown to be an effective learning tool thus far from the teacher’s perspective. Additional student feedback and analysis is forthcoming . Swivl has the potential to be an effective tool in ATC training and may enhance learning by allowing students to sharpen skills that are necessary to advance in the field of air traffic control. The air traffic control - training academy (used to train air traffic controllers hired by the federal government) has a high failure rate. Incorporating digital learning tools in that setting may increase success rates as well

An assessment of the benefits of yellow Sigatoka (Mycosphaerella musicola) control in the Queensland Northern Banana Pest Quarantine Area

The banana leaf spotting disease yellow Sigatoka is established and actively controlled in Australia through intensive chemical treatments and diseased leaf removal. In the State of Queensland, the State government imposes standards for de-leafing to minimise the risk of the disease spreading in 6 banana pest quarantine areas. Of these, the Northern Banana Pest Quarantine Area is the most significant in terms of banana production. Previous regulations imposed obligations on owners of banana plants within this area to remove leaves from plants with visible spotting on more than 15 per cent of any leaf during the wet season. Recently, this leaf disease threshold has been lowered to 5 per cent. In this paper we examine the likely impact this more-costly regulation will have on the spread of the disease. We estimate that the average net benefit of reducing the diseased leaf threshold is only likely to be $1.4 million per year over the next 30 years, expressed as the annualised present value of tightened regulation. This result varies substantially when the timeframe of the analysis is changed, with shorter time frames indicating poorer net returns from the change in protocols. Overall, the benefit of the regulation change is likely to be minor

Parental attitudes toward disclosure of the mode of conception to their child conceived by in vitro fertilization

OBJECTIVES: To survey the level of disclosure of conception method within families of children conceived using conventional IVF or ICSI and to examine the factors that may influence parental attitudes and plans for disclosure. DESIGN: An in-depth questionnaire. SETTING: Participants recruited through UK fertility clinics. PATIENTS: Parents of IVF/ICSI children aged 5-6 years (n=181, 51%). INTERVENTION: Mothers and fathers of IVF/ICSI children were sent questionnaires to complete and return in a reply paid envelope. MAIN OUTCOME MEASURES: Completion of the questionnaire. RESULTS: Most parents had told somebody about their child’s method of conception, mostly close friends and family. Fewer (26% mothers/17% fathers) had already discussed the child’s mode of conception with their child. 58% mothers/57% fathers intended to tell their child at some point. 16% mothers/21% fathers were undecided. 4% fathers never wanted to discuss the subject with their child. Children were more likely to be told if conception was ICSI, rather than conventional IVF, and if an only child. 29% undecided fathers and 36% undecided mothers stated that they would tell their child if appropriate child-friendly explanatory literature was available. CONCLUSIONS: The majority of parents wish to tell their child at some point but are unsure about the most appropriate timing and method of disclosure. Fertility clinics may have a role in providing the necessary support. Child-friendly literature may be helpful

The modelling gap : quantifying the discrepancy in the representation of thermal mass in building simulation

Enhanced fabric performance is fundamental to reduce the energy consumption in buildings. Research has shown that the thermal mass of the fabric can be used as a passive design strategy to reduce energy use for space conditioning. Concrete is a high density material, therefore said to have high thermal mass. Insulating concrete formwork (ICF) consists of cast in-situ concrete poured between two layers of insulation. ICF is generally perceived as a thermally lightweight construction, although previous field studies indicated that ICF shows evidence of heat storage effects. There is a need for accurate performance prediction when designing new buildings. This is challenging in particular when using advanced or new methods (such as ICF), that are not yet well researched. Building Performance Simulation (BPS) is often used to predict the thermal performance of buildings. Large discrepancies can occur in the simulation predictions provided by different BPS tools. In many cases assumptions embedded within the tools are outside of the modeller's control. At other times, users are required to make decisions on whether to rely on the default settings or to specify the input values and algorithms to be used in the simulation. This paper investigates the “modelling gap”, the impact of default settings and the implications of the various calculation algorithms on the results divergence in thermal mass simulation using different tools. ICF is compared with low and high thermal mass constructions. The results indicated that the modelling uncertainties accounted for up to 26% of the variation in the simulation predictions

Utilizing Guided Simulation in Conjunction with Digital Learning Tools in Air Traffic Control Training

For students in an air traffic control discipline, simulated training time is limited to in - class time and is divided among the entire class. Students are required to advance and obtain knowledge, skills, and abilities in the lab because there is almost no way to practice at home. All students learn at different rates as well as through different learning styles. Swivl is a digital learning/capture tool designed to enhance student learning by allowing students to refer back to the individual classroom lab training session via an online portal. Swivl is currently being used in two ATC Lab courses. There are two technological deficiencies that have arisen: (1) Swivl (in the Terminal Radar Approach Control and En - Route Radar environments) lacks the ability to record what is being said over the frequencies. (2) Swivl does not have the ability to focus on the radar scope targets. As a result, the students’ captures have a deficiency in visual clarity. However, the nature of the tower simulator does allow for better visual acuity and effective communication exchange within the Swivl capture

A Design-of-Experiments Approach to Developing Thermoresponsive Gelators From Complex Polymer Mixtures

© 2020 Royal Society of Chemistry. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1039/D0ME00093K.This study investigated the effects of additives on the properties of poloxamer (P) 407 thermogels, employing a design-of-experiments (DoE) approach. P407 is a thermoresponsive triblock copolymer that exhibits a solution to gel transition at a critical temperature, typically between 15-25 °C, dependant on polymer concentration. This thermoresponsive gelation has made P407 attractive for many applications including drug delivery, cell culture and tissue engineering. However, the gels formed do not have sufficient strength for some applications where the materials will be exposed to shear, such as topical drug delivery. There have been attempts to improve P407 thermogel properties by the addition of other hydrophilic polymers. However, these studies were limited to a small number of polymers, typically in binary mixtures, exploring one variable at a time. In this study, a DoE approach was carried out using a two-level model exploring P407, P188, poly(vinyl alcohol), poly(ethylene glycol), and poly(acrylic acid) as variables, including an exploration of molecular weight of the latter three additives. The variables were given two different levels (concentrations) to generate a total of 16 training formulations. The thermoresponsive gelation of these 16 formulations was studied by rheometry and predictive models built for gel strength (G’) and gelation temperature (Tgel) responses. The model was able to predict the thermoresponsive gelation of complex octonary test blends, significantly streamlining formulation development processes relative to current methods. The model was then able to identify novel thermoresponsive gel formulations with 20 % improved gel strength compared to a standard 20 % P407 solution, which may be used as temperature-responsive materials for advanced healthcare applications.Peer reviewe

Integrating Unmanned Aircraft Operations into the National Airspace System

Commercial unmanned aircraft systems (UAS) are expected to dominate the National Airspace System (NAS) in the years to come. One particular barrier preventing integration of UAS into the NAS is the lack of standardized procedures for separating aircraft and communicating with ATC. In preparation for adopting unmanned flight operations into a complex control system, it is important to identify solutions to effectively control UAS in the NAS. The Joint UAS and ATC Team (JUAT) group has designed several simulated ATC scenarios in order to determine effective solutions for integration. Through the use of digitized radar display overlays that replicate the military grid reference system (MGRS) in conjunction with traditional airspace sectors/boundaries the JUAT is able to simulate UAS operations on a basic level
