Compressive sensing is one of teh cost effective solution towards performing compression of heavier form of signals. We reviewed the existing research contribution towards compressive sensing to find that existing system doesnt offer any form of optimization for which reason the signal are superiorly compressed but at the cost of enough resources. Therefore, we introduce a framework that optimizes the performance of the compressive sensing by introducing 4 sequential algorithms for performing Random Sampling, Lossless Compression for region-of-interest, Compressive Sensing using transform-based scheme, and optimization. The contribution of proposed paper is a good balance between computational efficiency and quality of reconstructed medical image when transmitted over network with low channel capacity. The study outcome shows that proposed system offers maximum signal quality and lower algorithm processing time in contrast to existing compression techniuqes on medical images.

The prevalence of wounds and the cost of treating them are increasing year on year. Improving the quality of wound care will improve patient outcomes and is a financial necessity. The Lens of Profound Knowledge is a tool that can be used to support quality improvement and identify where action is needed. It allows exploration of an organisation through four aspects—appreciate the system, understanding variation, psychology, and theory of knowledge—and working on all four aspects simultaneously is believed to increase the likelihood of achieving improvement. Improvements at and between all levels—microsystem (such as frontline services), mesosystem (health boards) and macrosystem (NHS Scotland)—would reduce variation in practice and prove to be both clinically and cost-effective. Given the rapidly growing population of people with unhealed wounds, wound care needs to be valued at all system levels and be adequately resourced.

Wavelet based denoising is an effective way to improve the quality of images. Various methods have been proposed for denoising using real-valued wavelet transform. Complex valued wavelets exist but are rarely used. The complex wavelet transform provides phase information and it is shift invariant in nature. In medical image denoising, both removal of phase incoherency as well as maintaining the phase coherency are needed. This paper is an attempt to explore and apply the complex Daubechies wavelet transform for medical image denoising. We have proposed a method to compute a complex threshold, which does not depend on any assumed model of noise. In this sense this is a "universal" method. The proposed complex-domain shrinkage function depends on mean, variance and median of wavelet coefficients. To test the effectiveness of the proposed method, we have computed the input and output SNR and PSNR of various types of medical images. The method gives an improvement for Gaussian additive, Speckle and Salt-&-Pepper noise as well as for the mixture of these noise types for a range of noisy images with 15 db to 30 db noise levels and outperforms other real-valued wavelet transform based methods. The application of the proposed method to Ultrasound, X-ray and MRI images is demonstrated in the experiments.

Context: Stroke is one of the main causes of premature death and disability, imposing significant costs on the healthcare system, especially due to expensive hospital care. Home care service is one of the interventions used in the last two decades to reduce the cost of services provided for stroke patients in different countries. Objectives: The present study aimed to systematically review studies related to the economic evaluation of home care compared to hospital care for stroke patients. Data Sources: A search was conducted between January 1990 and January 2021. PubMed, Scopus, Web of Science, and Embase databases were searched systematically. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to select the studies. Data Extraction: To evaluate the quality of studies included in this systematic review, Drummond’s ten-item checklist was used. Results: Five economic evaluation studies were included in this review. The included studies reported different results regarding the effect of home care on improving different indicators and the cost-effectiveness ratio of home care to hospital care. Most previous studies reported that home care is a more cost-effective option for improving many indicators, such as physical function and quality-adjusted life years (QALY), and for reducing mortality and institutionalization, compared to hospital care. Conclusions: Home care is a more cost-effective option than hospital care for stroke patients with regard to some indicators, such as the Barthel index for Activities of Daily Living, Modified Rankin Scale (mRS), quality of life, mortality, and institutionalization. However, there are some exemptions to this conclusion. Due to limitations, such as heterogeneity of interventions in the existing studies, different levels of patients’ disabilities, different perspectives toward economic evaluation, and differences in the healthcare systems of countries, further research is needed according to the context of each country based on clinical trials.

The increasing number of problems that need to be addressed in the hospital sector calls for innovation in this field. It brings us the need to find cost-effective and memory-efficient solutions to handle the vast data and sector it into essential information to operate on the patient. There used to be many systems to manage clinical records which are fixed at a place. It is quite complicated to get the information and make this data available at a patient's bedside. This leads to a considerable amount of wasted time in moving to those storage PCs and also the cost afforded is comparatively high. A computer system that controls and accomplishes all the data in the hospital database to provide effective healthcare is called hospital information system (HIS). The introduction of HIS made billing and inventor easier for the staff. This paper discusses diverse methods that improve the cost, demands of HIS, and provide techniques to function efficiently using wireless networks. Also, the paper gives a comparative study on different aspects such as cost, quality of service, transportation, and security. A new system is proposed by combining the wireless healthcare system along prioritized alert notification.

In 2016, the U.S. Government health expenditures reached $3.35 trillion and the cost per person stood at $10,345. Health is seen as impacting both one's quality of life and finances. The Affordable Care Act (ACA) (2008 - 2016) brought the issue of cost to the forefront for all people especially those in the health disparate communities. Advances in health informatics coupled with new approaches to healthcare delivery may hold promise for this large industry in the USA that critically needs to be cost effective in order to sustain itself. This paper reports a study that investigated importance of health, mobile health (m-Health) and telemedicine awareness along with its adoption in a health disparate community that has one of the Historical Black Colleges & Universities (HBCUs) in the country. The findings were that, all participants owned a mobile (cell) phone with smart features. Although a large number them indicated that their health was very important to them, there was lack of awareness and adoption of m-Health and telemedicine.

A region of interest (ROI)-based compression method for medical image datasets is a requirement to maintain the quality of the diagnostically important region of the image. It is always a better option to compress the diagnostic important region in a lossless manner and the remaining portion of the image with a near-lossless compression method to achieve high compression efficiency without any compromise of quality. The predictive ROI-based compression on volumetric CT medical image is proposed in this paper; resolution-independent gradient edge detection (RIGED) and block adaptive arithmetic encoding (BAAE) are employed to ROI part for prediction and encoding that reduce the interpixel and coding redundancy. For the non-ROI portion, RIGED with an optimal threshold value, quantizer with optimal [Formula: see text]-level and BAAE with optimal block size are utilized for compression. The volumetric 8-bit and 16-bit standard CT image dataset is utilized for the evaluation of the proposed technique, and results are validated on real-time CT images collected from the hospital. Performance of the proposed technique in terms of BPP outperforms existing techniques such as JPEG 2000, M-CALIC, JPEG-LS, CALIC and JP3D by 20.31%, 19.87%, 17.77%, 15.58% and 13.66%, respectively.

Introduction: Chronic, non-healing ulcers remain one of the most challenging clinical situations for health care practitioners. Often, conventional treatments fail and lead to amputation, further decreasing the patient's quality of life and resulting in enormous medical expenditures for healthcare systems. Here we evaluated the use of and cost-effectiveness of the RGTA (ReGeneraTing Agents) medical device CACIPLIQ20 (OTR4120) for chronic lower-extremity ulcers in patients with Leriche and Fontaine Stage IV peripheral arterial disease who were not eligible for revascularization. Methods: This uncontrolled pilot study included 14 chronic lower extremity ulcers in 12 patients in one hospital. The pilot study included 12 patients with TcPO2 < 20 mm Hg and ABPI < 0.5 who had either a minimum of one chronic lower extremity ulcer or a chronic ulcer related to amputation. OTR4120 was applied twice a week or until complete healing, for up to 12 weeks. Ulcer surface area reduction (%)after 2, 4, 8 and 12 weeks, appearance after 4 weeks, and healing after 12 weeks were measured and recorded. Results: A 35% reduction in ulcer size was achieved after 4 weeks. 7 (50%) out of 14 ulcers completely healed within 1 to 3 months of treatment. Discussion: OTR4120 is an effective therapeutic option for patients with chronic lower extremity ulcers, can provide major improvement of quality of life and has the added benefit of being a significant cost-effective solution for healthcare systems.

Mechanical felling is the cost-effective solution for harvesting short-rotation poplar plantations, but the damage inflicted by conventional shear cutting devices on tree stumps has raised concerns about stump mortality and re-sprouting vigor - both crucial to coppice regeneration. In order to determine if such concerns are justified, the experiment monitored the survival and resprouting vigor of eleven sample blocks, composed of two 10-stump row segments cut according to either of two methods: 1) lternately with a chainsaw (control) or 2) and with an excavator-mounted shear. The sample blocks were located within the same plantation, established 7 years earlier with hybrid poplars (Populus nigra x P. deltoides), belonging to the "AF8" clone. One year after cutting, no differences were found between treatments in terms of stump mortality, number of shoots per stump, shoot diameter at 30 cm from the insertion and shoot height. These results support the use of mechanical shears to fell short-rotation poplar coppice. However, further studies should be conducted on multiple fields and clones for a safe generalization of this preliminary study.
