Introduction: Prompting devices for chest compressions have been advocated as a means of improving CPR quality in previous AHA guidelines. Studies have shown overall CPR quality improves with the use of these devices. Hypothesis: This study compared the impact of prompting devices on providers with varying levels of experience and proficiency. Methods: A convenience sample of 53 subjects with varying degrees of CPR experience, ranging from zero to frequent opportunities to perform CPR, were enrolled. Using a skills recording CPR manikin, data on each subject’s chest compression performance was obtained. All subjects performed an initial one-minute cycle of continuous chest compressions with no prompting device. After a brief rest, subjects were randomized to use one of two CPR prompting devices (Philips MRX with Q-CPR or Laerdal Medical CPRmeter). An additional one minute of CPR was conducted with the first device. Subjects were then crossed over to use the other prompting device after another brief rest. Results: Across the entire group, nearly all parameters significantly improved with the prompting devices, confirming previous studies on the efficacy of CPR prompting devices. However, when subjects’ results were examined by breaking the group into three performance levels (high, medium and low) based on the Overall CPR Score generated by the manikin software, there were differences in performance. Paired t -tests were conducted on the low and high performance groups. The low-level group significantly improved across 7 of 8 variables with both devices. The high-level group had only minor changes from baseline (both positive and negative) in most variables, but had significant or near significant decrease in proficiency in one variable - percent correctly released compressions ( p = 0.011 for Philips device; p = 0.052 for the Laerdal device). Conclusions: CPR prompting devices improve the overall quality of chest compressions. Individuals with existing high performance CPR skills could be distracted by the device, reducing the quality of compressions compared to using no device. When a CPR prompting device is introduced into a health care system, all providers, especially high performers, require practice with the device in order to acclimate to its use.

The Impact

The objective of this experiment is to assess clinician perceived versus actual compression quality, and to evaluate the impact of using feedback from the Laerdal CPRMeter2 on compression quality.  In our setup, we have a total of eighty four participants (43 from the Royal Alex and 41 from the Misericordia hospital). We monitored CPR quality based on the guidelines by Heart and Stroke, which breaks down chest compression effectiveness into three areas- Release, Depth and Rate. Proper Guidelines: Compress the chest at least 5cm (2inches); Compress at a rate of 100 to 120 beats per minute; Allow the chest to recoil completely after each compression. Clinical Setup: A convenience sample of participants performed two minutes of uninterrupted chest compressions on a Laerdal Resusci Anne with a CPRmeter2 on top without feedback, followed by a two minute rest period to fill out a Q.I tracking form. They later repeated the two minutes of chest compressions with the display of the CPRmeter uncovered, with the feedback visible. The chest compression metrics from the trials were compared using a data tracking form. From the data collected, enough evidence shows that the CPRmeter2 is able to improve release, rate and overall CPR quality. After filling out the survey, all of the nurses agree that the device is very useful in giving feedback and should be used in future CPR classes. Furthermore, data collected from the Q.I tracking forms indicates that nurses and other health clinicians are inadequate in predicting their own CPR abilities. Often times, nurses would either overpredict or underpredict their scores on the CPR meter. From the data gathered, the CPRmeter2 is going to be used for training in future CPR classes. Just recently, the device has been incorporated into code calls in the emergency department at the Misericordia. A T-test was done on the findings from the experiment to test if the means of two sets of data are significantly different from each other. Based on our findings, the t-test values for rate, release, and overall quality are statistically significant, meaning that the null hypothesis is rejected.

Abstract Background Hemodialysis is a medical technology implemented for various renal diseases and has a significant budget impact in Japan. Hemodialysis also affects health-related quality of life, as it interferes with daily life, but the effect of diagnosis and duration of hemodialysis is not clear. The purpose of this study was to examine the impact of hemodialysis on health-related quality of life, with a focus on diagnosis and duration of hemodialysis. Methods We conducted EQ-5D-5L surveys among hemodialysis patients at a single hemodialysis hospital between November 2015 and September 2017 and used a scoring algorithm that was developed in Japan to calculate the scores. Results A total of 274 subjects without missing data were included in the data analysis. The mean score of the entire group was 0.772 ± 0.215. Compared with other domains, pain/discomfort had the highest percentage of problems (59.1%). There were no differences in the distributions with respect to diagnostic names in any domain. Multiple regression analysis showed that hemodialysis duration was the only explanatory variable that had a mild significant effect on EQ-5D-5L scores, but it was not large. Conclusions QOL measured using the EQ-5D-5L survey score was not affected by age, gender, or diagnosis but was affected by hemodialysis duration. Future studies are needed to investigate the impact of prolonged hemodialysis on health-related quality of life.

Forest fires are a major risk factor with strong impact at eco-environmental and socio- economical levels, reasons why their study and modeling are very important. However, the models frequently have a certain level of uncertainty in some input parameters given that they must be approximated or estimated, as a consequence of diverse difficulties to accurately measure the conditions of the phenomenon in real time. This has resulted in the development of several methods for the uncertainty reduction, whose trade-off between accuracy and complexity can vary significantly. The system ESS (Evolutionary- Statistical System) is a method whose aim is to reduce the uncertainty, by combining Statistical Analysis, High Performance Computing (HPC) and Parallel Evolutionary Al- gorithms (PEAs). The PEAs use several parameters that require adjustment and that determine the quality of their use. The calibration of the parameters is a crucial task for reaching a good performance and to improve the system output. This paper presents an empirical study of the parameters tuning to evaluate the effectiveness of different configurations and the impact of their use in the Forest Fires prediction.

The influence of employees’ challenges on productivity at a provincial department in KwaZulu-Natal has been notably affecting the overall provision of houses and sanitation (service delivery). According to the Annual Performance Plan 2013/14 – 2015/16, the improvement of efficiency and quality of human settlements’ services is one of the strategic goals which focuses on the overall organisational productivity; however, it fails to consider employees’ day-to-day challenges. Thus, the primary purpose of this paper is to investigate challenges at an operational level and determine the impact they have on productivity. Using a quantitative approach, a questionnaire was distributed to a convenience sample of 180 employees within the department. Applying factor analysis, the findings indicate Leadership as having the highest impact while Work-Life Balance displayed the least impact on Organisational Productivity. The results of this study are beneficial to other local, provincial and national public entities.

The Impact

Background: Cardiopulmonary Resuscitation (CPR) is one of the measures to deal with emergency cardiac arrest (cardiac arrest) where the heart organ loses its function suddenly. Hence it is unable to pump blood throughout the body. CPR consists of aid in circulation (compression) and breathing (ventilation). AHA has determined guidelines for implementing CPR, especially an essential point in CPR, namely chest compression. The standing position is fundamental in the implementation of CPR, but kneeling and footstool positions can be carried out during CPR implementation. This paper aims to show the impact of standing, kneeling, and footstool positions on CPR quality.Method: The method used is by searching journals in Science Direct, PubMed, and Google Scholar. The keywords used are CPR, Kneeling Position, Footstool, standing beside the bed Obtained eight selected journals according to the topic, then analyzed.Results: Based on the search result, eight articles meet the criteria. The literature review results showed three positions that can be chosen when conducting CPR: standing, kneeling, and footstool. Those positions could give impact toward helper: pain level and exhaustion degree, and quality of CPR: compression strength, depth of compression, amount of compression, chest recoil, elbow movement, and movement in the lower back.Conclusion: Three CPR positions can be done, including standing beside the bed, kneeling, and standing on stepstool footing. Each position gives impacts both to helper condition and CPR quality. Researchers recommend standing on stepstool footing due to it provides the best effect on CPR quality.

Intended Effect

In this chapter, we provide empirical evidence that the underwriting of private sector loans through a loan guarantee programme distorts the efficient allocation of bank credit. We exploit cross-sectional and time series variation in the availability of loan guarantees to entrepreneurial firms in the Netherlands after the financial crisis to examine the impact of loan guarantees on a large sample of individual borrowers. The introduction and posterior withdrawal of the programme had the intended effect on the number of loan applications. Firms eligible for loan guarantees applied for more loans relative to those that were not. However, loan guarantees reduced the incentives on banks to screen and monitor the quality of loans by reducing collateralized loans and making riskier loans. Our findings suggest that government guarantee programmes may have adverse effects on the screening incentives of banks.

The Impact

With the advent of High Performance Computing (HPC) in the large-scale parallel computational environment, better job scheduling and resource allocation techniques are required to deliver Quality of Service (QoS). Therefore, job scheduling on a large-scale parallel system has been studied to minimize the queue time, response time, and to maximize the overall system utilization. The objective of this paper is to touch upon the recent methods used for dynamic resource allocation across multiple computing nodes and the impact of scheduling algorithms. In addition, a quantitative approach which explains a trend line analysis on dynamic allocation for batch processors is depicted. Throughout the survey, the trends in research on dynamic allocation and parallel computing is identified, besides, highlights the potential areas for future research and development. This study proposes the design for an efficient dynamic scheduling algorithm based on the Quality-of-Service. The analysis provides a compelling research platform to optimize dynamic scheduling of jobs in HPC.
