Machine-to-machine (M2M) communication is an emerging technology with unrivaled benefits in the fields of e Health and m-Health. The wireless body area networks (WBANs) consist of a major subdomain of M2M communications. The WBANs coupled with the Cloud Computing (CC) paradigm introduce a supreme infrastructure in terms of performance and Quality of Services (QoS) for the development of eHealth applications. In this article, a risk assessment aiming to disclose potential threats and highlight exploitation of health care services, is introduced. The proposed assessment is based upon the implementation of a series of steps. Initially, the health care WBAN-CC infrastructure is scrutinized; then, its threats' taxonomy is identified. Then, a risk assessment is carried out based on an attack-tree consisting of the most hazardous threats against Personally Identifiable Information (PII) disclosure. Thus, the implementation of several countermeasures is realized as a means to mitigate gaps.

Access To Health

Abstract Background Evidence often shows that migrants in the European region have poor access to quality health care. Having a large number of migrants seeking towards Europe, crossing through i.e. Serbia, it is crucial to improve migrants' access to health care and ensure equality in service provision Aim To investigate what are the barriers and facilitators of access to health care in Serbia, perceived by migrants, policy makers, health care providers, civil servants and experts working with migrants. Methods six migrants in an asylum center and eight civil servants in the field of migration were conducted. A complementary questionnaire to key civil servants working with migrants (N = 19) is being distributed to complement the data. The qualitative and quantitative data will be analysed through Grounded Theory and Logistic Regression respectively. Results According to preliminary findings, migrants reported that they were able to access the health care services quite easily. Migrants were mostly fully aware of their rights to access these health care services. However, the interviewed civil servants experienced that, despite the majority of migrants in camps were treated fairly, some migrants were treated inappropriately by health care professionals (being addressed inappropriately, poor or lacking treatment). The civil servants believed that local Serbs, from their own experiences, were treated poorer than migrants (I.e. paying Informal Patient Payments, poor quality of and access to health care services). The interviewed migrants were trusting towards the health system, because they felt protected by the official system that guaranteed them services. The final results will be presented at the conference. Conclusions There was a difference in quality of and access to health care services of local Serbs and migrants in the region. Migrants may be protected by the official health care system and thus have access to and do not pay additional fees for health care services. Key messages Despite comprehensive evidence on Informal Patient Payments (IPP) in Serbia, further research is needed to highlight how health system governance and prevailing policies affect IPP in migrants. There may be clear differences in quality of and access to health care services between the local population and migrants in Serbia.

AbstractThe Institute for Security and Social Services for State Workers (ISSSTE) is a large public provider of health care services that serve around 13.2 million Mexican government workers and their families. To attain process efficiencies, cost reductions, and improvement of the quality of diagnostic and imaging services, ISSSTE was set out in 2019 to create a digital filmless medical image and report management system. A large-scale clinical information system (CIS), including radiology information system (RIS), picture archiving and communication system (PACS), and clinical data warehouse (CDW) components, was implemented at ISSSTE’s network of forty secondary- and tertiary-level public hospitals, applying global HL-7 and Digital Imaging and Communications in Medicine (DICOM) standards. In just 5 months, 40 hospitals had their endoscopy, radiology, and pathology services functionally interconnected within a national CIS and RIS/PACS on secure private local area networks (LANs) and a secure national wide area network (WAN). More than 2 million yearly studies and reports are now in digital form in a CDW, securely stored and always available. Benefits include increased productivity, reduced turnaround times, reduced need for duplicate exams, and reduced costs. Functional IT solutions allow ISSSTE hospitals to leave behind the use of radiographic film and printed medical reports with important cost reductions, as well as social and environmental impacts, leading to direct improvement in the quality of health care services rendered.

Large employers have become increasingly involved in helping to set the agenda for quality measurement and improvement. Moreover, they are beginning to hold health care organizations accountable for their performance through marketplace incentives, including the public reporting of comparative quality data and the linkage of reimbursement to performance on quality measures. The Pacific Business Group on Health (PBGH) is an employer coalition that has been prominent in establishing models for collaborative quality measurement and improvement in the California marketplace. PBGH's involvement in quality stems from an environment in which purchasers were faced with high health care costs, yet virtually no information with which to assess the value their employees received from that care. Research indicating widespread variation in performance across health care organizations and seemingly limited oversight for quality of care within the industry has further motivated purchasers' efforts to better understand the quality of care being delivered to their em-ployees. Using the purchasing power of employers representing 2.5-million covered lives, PBGH endeavors to encourage the transition of the health care marketplace from one that competes solely on price to one that competes on price and quality. This entails collaborating with the health care industry to develop and publicly report valid performance data for use by both large employers and consumers of health care services. It also includes communicating to the marketplace purchasers' commitment to making purchasing decisions based on quality as well as cost. PBGH efforts to measure, report, and improve quality have been demonstrated by several undertakings in the perinatal care arena, including research to assess cesarean section rates and newborn readmission rates across California hospitals. employer coalition, purchaser, quality measurement, quality improvement, report cards, perinatal quality of care.

Stochastic Risk

Reimbursement for health care services is transferring more risk away from payers and toward health care providers in the form of Alternative Payment Models (APMs), also known as Value-Based Care (VBC) models. VBC models cover a wide variety of forms but all include guarantees by providers of services to improve quality of care and/or reduce cost. Types of risk include performance risk, contract design risk or stochastic risk (because of the random variation in health care services and costs). A form of contract risk that can be a significant driver of cost is model risk, defined as the probability that the savings calculated at contract reconciliation will deviate from the actual savings generated. To estimate the degree of risk we quantify the potential variance in outcomes in a naïve population prior to intervention and the components that could affect outcomes, using examples of maternity and type 2 diabetes. This analysis has implications for both participants in, and designers of value-based contracts.

OBJECTIVE To assess the inequalities in access, utilization, and quality of health care services according to the socioeconomic status. METHODS This population-based cross-sectional study evaluated 2,927 individuals aged ≥ 20 years living in Pelotas, RS, Southern Brazil, in 2012. The associations between socioeconomic indicators and the following outcomes were evaluated: lack of access to health services, utilization of services, waiting period (in days) for assistance, and waiting time (in hours) in lines. We used Poisson regression for the crude and adjusted analyses. RESULTS The lack of access to health services was reported by 6.5% of the individuals who sought health care. The prevalence of use of health care services in the 30 days prior to the interview was 29.3%. Of these, 26.4% waited five days or more to receive care and 32.1% waited at least an hour in lines. Approximately 50.0% of the health care services were funded through the Unified Health System. The use of health care services was similar across socioeconomic groups. The lack of access to health care services and waiting time in lines were higher among individuals of lower economic status, even after adjusting for health care needs. The waiting period to receive care was higher among those with higher socioeconomic status. CONCLUSIONS Although no differences were observed in the use of health care services across socioeconomic groups, inequalities were evident in the access to and quality of these services.
