Supervisory Algorithm for Autonomous Hemodynamic Management Systems

Future military conflicts will require new solutions to manage combat casualties. The use of automated medical systems can potentially address this need by streamlining and augmenting the delivery of medical care in both emergency and combat trauma environments. However, in many situations, these systems may need to operate in conjunction with other autonomous and semi-autonomous devices. Management of complex patients may require multiple automated systems operating simultaneously and potentially competing with each other. Supervisory controllers capable of harmonizing multiple closed-loop systems are thus essential before multiple automated medical systems can be deployed in managing complex medical situations. The objective for this study was to develop a Supervisory Algorithm for Casualty Management (SACM) that manages decisions and interplay between two automated systems designed for management of hemorrhage control and resuscitation: an automatic extremity tourniquet system and an adaptive resuscitation controller. SACM monitors the required physiological inputs for both systems and synchronizes each respective system as needed. We present a series of trauma experiments carried out in a physiologically relevant benchtop circulatory system in which SACM must recognize extremity or internal hemorrhage, activate the corresponding algorithm to apply a tourniquet, and then resuscitate back to the target pressure setpoint. SACM continues monitoring after the initial stabilization so that additional medical changes can be quickly identified and addressed, essential to extending automation algorithms past initial trauma resuscitation into extended monitoring. Overall, SACM is an important step in transitioning automated medical systems into emergency and combat trauma situations. Future work will address further interplay between these systems and integrate additional medical systems.

Management of Agitation in Dementia and Effects on Inpatient Length of Stay

Background Agitation associated with dementia impacts delivery of medical care and is a major reason for institutionalization in dementia patients. This study examines the association of medication use and other clinical factors with patients’ ‘dischargeability’ (i.e., amount of time until a patient is considered dischargeable from an inpatient unit). Methods This study was a retrospective chart review examining 200 patients with dementia and agitation, hospitalized at a Canadian acute care geriatric ward between November 2007 and November 2018. The main outcome measure was time until a patient was deemed dischargeable. Univariate linear regression analyses, followed by multiple linear regression analyses, were used. Results Risperidone and quetiapine were the most commonly prescribed medications, but were not associated with time until dischargeable. Olanzapine (40.9 vs. 16.2 days until dischargeable, β = 0.23, p = .001), regular benzodiazepine (32.7 vs. 16.5 days until dischargeable, β = 0.15, p = .027), and as-needed (‘PRN’) benzodiazepine use (31.7 vs. 15.9 days until dischargeable, β =0.19, p = .006) were independently associated with prolonging time until dischargeable. Conclusions Olanzapine, benzodiazepine, and PRN benzodiazepine use were associated with longer time until patients with dementia and agitation were considered ready for discharge. This raises the question as to whether the risks of these medications outweigh the benefits in a hospital setting.

Telemedicine in the United States: An Introduction for Students and Residents

Telemedicine refers to the delivery of medical care and provision of general health services from a distance. Telemedicine has been practiced for decades with increasing evidence proving its potential for enhanced quality of care for patients, reduction in hospital readmissions, and increase in savings for both patients and providers. The COVID-19 pandemic has resulted in a significant increase in the reliance on telemedicine and telehealth for provision of health care services. Developments in telemedicine should be structured as complements to current health care procedures, not with the goal of completely digitizing the entire health care system, but rather to use the power of technology to enhance areas that may not be working at their full potential. At the same time, it is also clear that further research is needed on the effectiveness of telemedicine in terms of both financial and patient benefits. We discuss the current and rapidly increasing knowledge about the use of telemedicine in the United States, and identify the gaps in knowledge and opportunities for further research. Beginning with telemedicine’s origins in the United States to its widespread use during the COVID-19 pandemic, we highlight recent developments in legislation, accessibility, and acceptance of telemedicine.

Hospital-based headache care during the Covid-19 pandemic in Denmark and Norway

Background The Covid-19 pandemic is causing changes in delivery of medical care worldwide. It is not known how the management of headache patients was affected by the lockdown during the pandemic. The aim of the present study was to investigate how the initial phase of the Covid-19 pandemic affected the hospital management of headache in Denmark and Norway. Methods All neurological departments in Denmark (n = 14) and Norway (n = 18) were invited to a questionnaire survey. The study focused on the lockdown and all questions were answered in regard to the period between March 12th and April 15th, 2020. Results The responder rate was 91% (29/32). Of the neurological departments 86% changed their headache practice during the lockdown. The most common change was a shift to more telephone consultations (86%). Video consultations were offered by 45%. The number of new headache referrals decreased. Only 36% administered botulinum toxin A treatment according to usual schemes. Sixty% reported that fewer patients were admitted for in-hospital emergency diagnostics and treatment. Among departments conducting headache research 57% had to halt ongoing projects. Overall, 54% reported that the standard of care was worse for headache patients during the pandemic. Conclusion Hospital-based headache care and research was impacted in Denmark and Norway during the initial phase of the Covid-19-pandemic.

Possibilities, difficulties and prospects for using telemedicine technologies in the field of pediatric oncohematology

Telemedicine is an integral health service in conditions when distance is a critical factor for both the delivery of medical care and the physicians’ trainings. Nowadays due to significant location remoteness, a pronounced personnel shortage as well as the necessity to make complex diagnostic and therapeutic decisions that often require a multidisciplinary communication, telemedicine allows to promote the quick delivery of quality medical services. Telemedicine today is a tool that may be considered to optimize the logistics of medical care and to reduce the financial costs of clinics. The article presents a brief report on the Center’s activities in the field of “telemedicine” and identifies the main difficulties and prospects for this work.

Conceptualizing difference: an analysis of physicians’ views on delivering care to asylum seekers

Background International migration leads to an increasingly fluctuating and superdiverse migrant population in reception countries. In Germany, structural, legal, social and political barriers to adequate care complicate the ability of health care professionals to respond to the challenges associated with caring for such a dynamic patient population. In this analysis, we explore the views of physicians working with asylum seekers and refugees in Germany, and aim to identify the barriers and enablers they face in providing appropriate care. Methods We performed a secondary qualitative analysis of 16 semi-structured interviews conducted for two studies on the delivery of medical care to asylum seekers in Germany. To examine physicians' views towards their work with asylum seekers, we analysed evaluative judgements on interpersonal and workplace factors, the external environment, the physician's own self, and individual medical conduct. Analysis was conducted by identifying cross-cutting themes through thematic analysis and mapping these onto a framework matrix. Results We found that evaluative judgements made by physicians providing care to asylum seekers emphasized one of three conceptualisations of “difference”: regarding personal or cultural attributes of the patient group; the spaces of care provision; or the context of asylum seeking patients. Emphasis on differences of the patient population and the spaces of care provision to asylum seekers was found to impede appropriate care, while physicians emphasizing contextual factors reported more responsive medical practices. Discussion Our findings suggest that processes of “othering” asylum seekers as a patient group as well as the heterotopic spaces of care provision endanger the doctor-patient relationship and responsiveness of care. Appropriate training, physical and human resources and encouraging support between physicians working with asylum seeking patients could alleviate these processes. Key messages Physicians’ conceptualisations of “difference” in providing care to asylum seekers focus on the patient group, workplace, or structural context; and affect the way in which medical care is provided. Structural competency training, resource investments, and clear structures could reduce physicians’ experiences of “difference” of the patient group and workplace, and facilitate responsive care.

Unhealthy Politics

The U.S. medical system is touted as the most advanced in the world, yet many common treatments are not based on sound science. This book sheds new light on why the government's response to this troubling situation has been so inadequate, and why efforts to improve the evidence base of U.S. medicine continue to cause so much political controversy. The book paints a portrait of a medical industry with vast influence over which procedures and treatments get adopted, and a public burdened by the rising costs of health care yet fearful of going against “doctor's orders.” It offers vital insights into the limits of science, expertise, and professionalism in American politics. The book explains why evidence-based medicine is important. First, the delivery of unproven care can expose patients to serious risks. Second, the slow integration of evidence can lead to suboptimal outcomes for patients who receive treatments that work less well for their conditions than alternatives. Third, the failure to implement evidence-based practices encourages wasteful spending, causing the health care system to underperform relative to its level of investment. This book assesses whether the delivery of medical care in the United States is evidence based. It argues that by systematically ignoring scientific evidence (or the lack thereof), the United States is substantially out of balance.

Introduction

This introductory chapter explains why evidence-based medicine is important. The sluggish incorporation of medical evidence into clinical practice is a concern for three key reasons: safety, quality, and the efficiency of resource allocation. First, the delivery of unproven care can expose patients to serious risks. Second, the slow integration of evidence can lead to suboptimal outcomes for patients who receive treatments that work less well for their conditions than alternatives. Third, the failure to implement evidence-based practices encourages wasteful spending, causing the health care system to underperform relative to its level of investment. This book assesses whether the delivery of medical care in the United States is evidence based. It argues that by systematically ignoring scientific evidence (or the lack thereof), the United States is substantially out of balance.

Assessment of the risk of developing complications ssessment of the risk of developing complications of chronic cholecystitis by a medical assistant of f chronic cholecystitis by a medical assistant of independent practice ndependent practice

The purpose of the study was to justify a model, a personified assessment of the risk of developing complications of chronic cholecystitis based on mathematical modeling. The factors were identified and their impact on the risk of developing complications of chronic cholecystitis was assessed based on a systemic multivariate analysis. Results. It has been established that based on the analysis of risk factors for complications of chronic cholecystitis, using the method of formalized assessment, the medical assistant of independent practice has the ability to create an individual (personal) prevention program. Conclusion. Further study of the application of the method of formalized assessment in the analysis of risk factors for the development of diseases of the digestive system is necessary. Individualization of approaches to preventive work will make it possible to more efficiently organize patient-oriented delivery of medical care in the context of primary health care.
