SiC crystal is an excellent substrate material for high power electronic devices and high-frequency electronic devices. Being cost-effective and defect-free are the two biggest challenges at present. For the physical vapor transport (PVT) growth of a SiC single crystal, SiC powder is used as the source material, which determines the cost and the quality of the crystal. In this paper, we propose a new design in which graphite blocks are substituted for the non-sublimated SiC powder. Temperature distribution in the SiC powder, the evolution of the SiC powder, and the vapor transport are investigated by using finite element calculations. With the addition of graphite blocks, the utilization and sublimation rate of SiC powder is higher. In addition, the reverse vapor transport above the SiC powder is eliminated. This design provides a new idea to reduce the cost of SiC crystals in industrialization.

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.

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.

Production of high precision circular scales is a complicated process requiring expensive equipment and complex processes to achieve. Precision angle measurement equipment tends to be very expensive and therefore not accessible to all in need. Simplification of production of such devices can lead to reducing costs of angle measurement systems ensuring easier accessibility. A new method of producing precision circular scales using low cost mass production can reduce the costs of these devices drastically. Therefore, utilising a common CD technology as the basis for such scales is analysed. This paper deals with the analysis of the newest laser cutting method for plastic circular scales. Preliminary results of manufacturing such scales are presented in the paper as well as measurements of the grating of the scale were performed. The quality of different scales manufactured using different laser types is analysed in the study. The cost – effective alternative of manufacturing circular scales is discussed in the paper.

Background Acupuncture is increasingly offered as a treatment for chronic pain, but continued treatment is expensive. Self acupuncture might offer a cost effective alternative. The aim of this project was to investigate the effectiveness and safety of self acupuncture in a pain clinic. Methods A retrospective audit was conducted by postal questionnaire of all patients with chronic pain who were taught self acupuncture as a home pain management strategy in the previous three years. The study was conducted by a researcher not involved in the patient's treatment. The patients selected for self acupuncture were those who had responded to acupuncture previously, met certain criteria, and had been taught self acupuncture successfully. Patients were taught self acupuncture using three acupuncture points (LI4, ST44, LR3). Results Of 52 eligible patients (70% female) who were approached, 38 valid questionnaires were returned, giving a response rate of 73.1%. Of these, 76.3% were female; 86.8% (33) still used self acupuncture and 13.3% (5) had stopped; 86.8% of the patients continued to experience pain reduction with self acupuncture. The reported pain relief gained was 5.7 (SD 2.6) measured on a visual analogue scale, improvement in quality of life was reported by 73.7% and no serious adverse effects were reported. Conclusion This audit suggests that self acupuncture is effective for pain relief and improves quality of life in this selected group of patients. Safety can be maintained provided that pre-selection is done with care, and appropriate training is carried out. Self acupuncture has considerable potential to reduce clinic waiting lists and appointment times for patients. Further research is required to determine the cost effectiveness of this approach.

Abstract Adult, Philadelphia chromosome-positive, Acute Lymphoblastic Leukemia (Ph-positive ALL) had a poor prognosis, but with the use of an initial BCR/ABL tyrosine kinase inhibitor such as Dasatinib in conjunction with chemotherapy such as hyper-CVAD, the projected 24 month disease free survival is 64%. More recently Foa et al. on behalf of the GIMEMA investigators published a phase II trial of Dasatinib and Blinatumomab as initial therapy for adults with ALL. The complete remission rate was 98%, and the projected disease-free survival at 24 months is 88%. We wished to analyze the incremental cost-effectiveness ratio (ICER) of the Dasatinib and Blinatumomab therapy as compared to Dasatinib and hyper-CVAD. The comparison is based on retail costs of chemotherapy for Dasatinib, Blinatumomab and hyperCVAD and excluded hospital and outpatient charges. The cost of hyperCVAD is based on treatment of a person with a BSA I.8m2. The retail cost of therapy is shown below. Drug Dose Cost Dasatinib 100 mg $505.67 Blinatumomab 1 mg $126.81 Cyclophosphamide 1,000 mg $231.00 Mesna 1,000 mg $42.89 Vincristine 2 mg $18.52 Dexamethasone 40 mg $4.12 Cytarabine 100 mg $22.88 Leucovorin 25 mg $7.48 The ICER formula is the cost of new therapy minus (-) the cost of standard therapy/quality of adjusted life new therapy - the quality of adjusted life standard (QALY). The yearly cost of Hyper-CVAD and Dasatinib is $147,288.48 per QALY, whereas, the yearly cost of Dasatinib-Blinatumomab is $187,940.46 per QALY. The difference is $42,451.98 which is less than the 50,000-threshold using cost-effective analysis. In conclusion, the combination of Dasatinib-Blinatumomab appears to be cost effective. Disclosures No relevant conflicts of interest to declare.

Background: Carcinoma cervix is the most common preventable cancer in women. The universal stain used in screening of pre-cancer and cancer cervix is papanicolaou stain. The objective of this study was to carry out to assess the quality of staining, cost effectiveness, duration of staining and preservation of staining of PAP stain in comparison with REAP stain.Methods: 200 smears were collected from 100 patients; one set of smears were stained with conventional PAP technique and other set with REAP technique. The ethanol bath in PAP technique is replaced with 1% acetic acid, tap water is used instead of scotts tap water in REAP technique. Methanol is used only for final dehydration. The two sets were assessed for optimal and suboptimal nuclear and cytoplasmic staining and the results were analysed.Results: Good cytoplasmic transparency and optimal nuclear details were seen in REAP stained smears when compared to the conventional PAP stain. The cost involved in REAP method was lesser when compared to PAP technique. REAP method took 7 minutes whereas PAP method involved 30 minutes.Conclusions: REAP technique produces better staining, cost effective and simple, with minimum use of alcohol. Involves minimal time for mass cervical cancer screening as compared to conventional PAP smears.

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.
