    Abstract Intensive care unit (ICU) service is resource-intense, finite, and valuable. The outcome of critically ill patients has improved because of a better understanding of disease pathology, technological developments, and newer treatment modalities. These improvements have however come at a price, with ICUs contributing significantly to health budgets. Several costing tools are used to assess cost. Accurate assessment has been hampered by the lack of standardized methodology and the heterogeneity of ICUs. In a costing exercise, the level of disaggregation (micro-costing vs gross-costing) and the method of costing (top-down vs bottom-up) need to be considered. Intensive care unit costing also needs to be viewed from the perspective of stakeholders. While all stakeholders aim to provide quality health care, objectives may vary. For the public health care provider, the focus is on optimizing expenditure; for the private health care provider it is bottomline; for a patient, it is affordability; for an insurance service provider, it is minimizing payout; and for the regulator, it is ensuring quality standards and fair pricing. The field of health economics deals with the application of the principles of cost-minimization, cost-effectiveness, cost-utility, and cost-benefit to identify treatments that result in the best outcome at the lowest cost, without limiting resources to other competing interests. In the ICU setting, studies on the efficient use of available resources, and interventions that reduce cost and minimize avoidable cost, would not only translate to cost savings, lives saved, and quality-adjusted life years gained but also enable policymakers to better allocate health care resources.

  7. Article: Approach to Thromboprophylaxis for Prevention of Venous Thromboembolism in COVID-19: Global Updates and Clinical Insights from India.

    Abstract Venous thromboembolism (VTE) frequently occurs in patients with coronavirus disease-19 (COVID-19) and is associated with increased mortality. Several global guidelines recommended prophylactic-intensity anticoagulation rather than intermediate-intensity or therapeutic-intensity anticoagulation for patients with COVID-19-related acute or critical illness without suspected or confirmed VTE. Even though standard doses of thromboprophylaxis are received, many cases of thrombotic complications are reported; hence, appropriate and adequate thromboprophylaxis is critical for the prevention of VTE in COVID-19. In spite of an increased prevalence of VTE in Indian patients, sufficient data on patient characteristics, diagnosis, and therapeutic approach for VTE in COVID is lacking. In this article, we review the available global literature (search conducted up to 31 May 2021) and provide clinical insights into our approach towards managing VTE in patients with COVID-19. Furthermore, in this review, we summarize the incidence and risk factors for VTE with emphasis on the thromboprophylaxis approach in hospitalized patients and special populations with COVID-19 and assess clinical implications in the Indian context.

    Abstract Fourier transform infrared spectroscopy (FTIR) has the potential to mark up the chemical changes of the materials, as almost all the materials contain their signatures in infrared region. Spectroscopy combined with spatial resolution enables the possibility of characterizing samples up to microscopic level. The emerging development of instrumentation to provide spatial information for infrared (IR) spectroscopy, termed as IR microscopy, provides an opening for newer applications in terms of image analysis, novel data processing tools, etc. Characterization of biomaterials using IR spectroscopy has a trace back to 1950s. The advent of FTIR with imaging capability made characterization possible in cartilage tissue and other biological systems. Extensive analysis of chemical constituents of cartilage and tendon, collagen orientation and polarization property of cartilage using FTIR imaging (FTIRI) has been actively explored during the last two decades. Also, studies using specialized instrumentations like synchrotron FTIR imaging have been attempted to understand the characteristics of biological samples like cartilage. This review covers most of those investigations on cartilage with FTIRI to characterize the same in terms of component characteristics and quantification, collagen orientation, zonal boundary determination, influence of mechanical compression on tissue nature and its correlation to other techniques in last 20 years.
