RESUMO
We computationally investigate a method for spatiotemporally modulating a material's elastic properties, leveraging thermal dependence of elastic moduli, with the goal of inducing nonreciprocal propagation of acoustic waves. Acoustic wave propagation in an aluminum thin film subjected to spatiotemporal boundary heating from one side and constant cooling from the other side was simulated via the finite element method. Material property modulation patterns induced by the asymmetric boundary heating are found to be non-homogenous with depth. Despite these inhomogeneities, it will be shown that such thermoelasticity can still be used to achieve nonreciprocal acoustic wave propagation.
RESUMO
The current universally challenging SARS-COV-2 pandemic has transcended all the social, logical, economic, and mortal boundaries regarding global operations. Although myriad global societies tried to address this issue, most of the employed efforts seem superficial and failed to deal with the problem, especially in the healthcare sector. On the other hand, the Internet of Things (IoT) has enabled healthcare system for both better understanding of the patient's condition and appropriate monitoring in a remote fashion. However, there has always been a gap for utilizing this approach on the healthcare system especially in agitated condition of the pandemics. Therefore, in this study, we develop two innovative approaches to design a relief supply chain network is by using IoT to address multiple suspected cases during a pandemic like the SARS-COV-2 outbreak. The first approach (prioritizing approach) minimizes the maximum ambulances response time, while the second approach (allocating approach) minimizes the total critical response time. Each approach is validated and investigated utilizing several test problems and a real case in Iran as well. A set of efficient meta-heuristics and hybrid ones is developed to optimize the proposed models. The proposed approaches have shown their versatility in various harsh SARS-COV-2 pandemic situations being dealt with by managers. Finally, we compare the two proposed approaches in terms of response time and route optimization using a real case study in Iran. Implementing the proposed IoT-based methodology in three consecutive weeks, the results showed 35.54% decrease in the number of confirmed cases.
RESUMO
AIM: The purpose of this research was to provide haemophilia treatment centres (HTCs) with guidance for the potential development of appropriate and timely interventions related to employment and vocational counselling and supports. METHODS: A multi-method approach was employed, where initial focus groups (n = 13) and review of the literature were used to construct a structured survey instrument (n = 75). RESULTS: Focus group participants made choices about employment with keen awareness of how their bleeding disorder might limit them physically; they described the role of social networks in career choices; and they wrestled with issues of disclosure. Among survey respondents, 47% per cent of respondents reported that haemophilia had a small negative impact, 27% felt that it had a moderate negative impact and 13% indicated that it had a very large negative impact. One-third of respondents had at some point received employment-related advice from a member of their haemophilia treatment centre team. Roughly two-thirds of respondents suggested that vocational advice would be "somewhat" or "very" useful at present. CONCLUSION: Canadian men with haemophilia continue to experience challenges related to employment and career development. There appears to be an opportunity for HTCs to incorporate additional supports on these topics into the range of services which they currently provide.

OBJECTIVES: Administration of oral corticosteroids at the onset of an upper respiratory tract infection (URTI) can be effective in the management of acute asthma exacerbations in children. This study was designed to identify barriers to parent-initiated implementation of clinical practice guideline-recommended use of oral corticosteroids for prophylaxis against severe asthma exacerbations in children. METHODS: Twenty-seven children who presented to BC Children's Hospital with URTI-induced asthma exacerbations were recruited. Parents received a filled prescription for a course of oral corticosteroids to be used at the earliest onset of their child's next URTI. Each family was contacted monthly over a 1-year period to inquire about URTI events, asthma symptoms, medication use and health care utilization. Focus groups were held with family physicians, paediatricians and parents; transcripts were analyzed qualitatively to identify key themes. RESULTS: Incidence of URTI events among participants was high (85%). Uptake of study medication was low; 44% used the medication as directed at their first URTI event. Eleven per cent of the patients who used the study medication also visited the emergency department for an exacerbation. Focus groups identified four main barriers to the effective use of parent-initiated oral corticosteroids: physician resistance and conflicting messages from providers; parent uncertainty about oral corticosteroids; multiple caregivers and relative ease of access to an emergency department. CONCLUSION: We have identified key barriers to the effective use of parent-administered oral corticosteroids as an asthma management strategy and gained important insights regarding the research that is required to enhance the applicability of the strategy.
RESUMO
New approaches to resource allocation are providing healthcare managers with ways to meet budget pressures while maximizing benefit to patients and populations. But putting these approaches in place often involves significant organizational change to which some degree of resistance must be expected. The authors have seen seven common objections raised time and again. Here, we offer our best advice on how healthcare leaders can anticipate and respond proactively to these challenges.
RESUMO
There are powerful arguments for increased investment in child and youth health. But the extent to which these benefits can be realized is shaped by health institutions' priority setting processes. We asked, "What are the unique features of a pediatric care setting that should influence choice and implementation of a formal priority setting and resource allocation process?" Based on multiple sources of data, we created a "made-for-child-health" lens containing three foci reflective of the distinct features of pediatric care settings: the diversity of child and youth populations, the challenges in measuring outcomes and the complexity of patient and public engagement.

Disasters can disrupt normal healthcare processes, with serious effects on children who depend upon regular access to the health care system. Children with medical complexity (CMC) are especially at risk. These children have chronic medical conditions, and may depend on medical technology, like feeding tubes. Without clear, evidence-based processes to connect with healthcare teams, families may struggle to access the services and supports they need during disasters. There is limited research about this topic, which has been pushed forward in importance as a result of the COVID-19 pandemic. The authors therefore conducted a rapid scoping review on this topic, with the intention to inform policy processes. Both the peer-reviewed and gray literatures on disaster, CMC, and communication were searched in summer 2020 and spring 2021. Twenty six relevant articles were identified, from which four main themes were extracted: 1. Cooperative and collaborative planning. 2. Proactive outreach, engagement, and response. 3. Use of existing social networks to connect with families. 4. Return to usual routines. Based on this review, good practices appear to involve including families, professionals, other stakeholders, and children themselves in pre-disaster planning; service providers using proactive outreach at the outset of a crisis event; working with existing peer and neighborhood networks for support; employing multiple and two-way communication channels, including social media, to connect with families; re-establishing care processes as soon as possible, which may include virtual connections; addressing mental health issues as well as physical functioning; and prioritizing the resumption of daily routines. Above all, a well-established and ongoing relationship among children, their caregivers, and healthcare teams could reduce disruptions when disaster strikes.

BACKGROUND: Resource allocation is a key challenge for healthcare decision makers. While several case studies of organizational practice exist, there have been few large-scale cross-organization comparisons. METHODS: Between January and April 2011, we conducted an on-line survey of senior decision makers within regional health authorities (and closely equivalent organizations) across all Canadian provinces and territories. We received returns from 92 individual managers, from 60 out of 89 organizations in total. The survey inquired about structures, process features, and behaviours related to organization-wide resource allocation decisions. We focus here on three main aspects: type of process, perceived fairness, and overall rating. RESULTS: About one-half of respondents indicated that their organization used a formal process for resource allocation, while the others reported that political or historical factors were predominant. Seventy percent (70%) of respondents self-reported that their resource allocation process was fair and just over one-half assessed their process as 'good' or 'very good'. This paper explores these findings in greater detail and assesses them in context of the larger literature. CONCLUSION: Data from this large-scale cross-jurisdictional survey helps to illustrate common challenges and areas of positive performance among Canada's health system leadership teams.

PURPOSE: Public sector interest in methods for priority setting and program or policy evaluation has grown considerably over the last several decades, given increased expectations for accountable and efficient use of resources and emphasis on evidence-based decision making as a component of good management practice. While there has been some occasional effort to conduct evaluation of priority setting projects, the literatures around priority setting and evaluation have largely evolved separately. In this paper, the aim is to bring them together. DESIGN/METHODOLOGY/APPROACH: The contention is that evaluation theory is a means by which evaluators reflect upon what it is they are doing when they do evaluation work. Theories help to organize thinking, sort out relevant from irrelevant information, provide transparent grounds for particular implementation choices, and can help resolve problematic issues which may arise in the conduct of an evaluation project. FINDINGS: A detailed review of three major branches of evaluation theory--methods, utilization, and valuing--identifies how such theories can guide the development of efforts to evaluate priority setting and resource allocation initiatives. Evaluation theories differ in terms of their guiding question, anticipated setting or context, evaluation foci, perspective from which benefits are calculated, and typical methods endorsed. ORIGINALITY/VALUE: Choosing a particular theoretical approach will structure the way in which any priority setting process is evaluated. The paper suggests that explicitly considering evaluation theory makes key aspects of the evaluation process more visible to all stakeholders, and can assist in the design of effective evaluation of priority setting processes; this should iteratively serve to improve the understanding of priority setting practices themselves.

BACKGROUND: The global COVID-19 pandemic led to rapid changes in both medical care and medical education, particularly involving the rapid substitution of virtual solutions for traditional face-to-face appointments. There is a need for research into the effects and impacts of such changes. The objective of this article investigates the perspectives of Family Medicine Residents in one university program in order to understand the impact of this transition to virtual care and learning. METHODS: This is a qualitative focus group study. Four focus groups, stratified by site type (Rural = 1; Semi-Urban = 1; Urban = 2) were conducted, with a total of 25 participants. Participants were either first or second-year Residents in Family Medicine. Focus group recordings were analyzed thematically, based upon a five-level socio-ecological model (individual, family, organization, community, environment and policy context). RESULTS: Two main themes were identified: (1) Residents' experiences of Virtual Learning and Virtual Care, and (2) Living and Learning in Pandemic Times. In the first theme, Residents reported challenges both individually, in their family context, and in their training organizations. Of particular concern was the loss of hands-on experience with clinical skills such as conducting physical examinations. In the second theme, Residents reported disruption of self-care routines and family life. These Residents were unable to engage in the relationships outside of the workplace with their preceptors and peers which they had expected, and which play key roles in social support as well as in future decisions about practice location. CONCLUSIONS: While many patients appreciated virtual care, in the eyes of these Residents it is not the ideal modality for learning the practice of Family Medicine, and they awaited a return to normal times. Despite this, the pandemic has pointed out important ways in which residency training needs to adapt to an evolving world.

Moral distress is a concept used to date in clinical literature to describe the experience of staff in circumstances in which they are prevented from delivering the kind of bedside care they believe is expected of them, professionally and ethically. Our research objective was to determine if this concept has relevance in terms of key health care managerial functions, such as priority setting and resource allocation. We conducted interviews and focus groups with mid- and senior-level managers in two British Columbia (Canada) health authorities. Transcripts were analyzed qualitatively using constant comparison to identify key themes related to moral distress. Both mid- and senior-level managers appear to experience moral distress, with both similarities and differences in how their experiences manifest. Several examples of this concept were identified including the obligation to communicate or 'sell' organizational decisions or policies with which a manager personally may disagree and situations where scarce resources compel managers to place staff in situations where they meet with predictable and potentially avoidable risks. Given that moral distress appears to be a relevant issue for at least some health care managers, further research is warranted into its exact nature, prevalence, and possible organizational and personal responses.

Although the costs of doctors' visits and hospital stays in Canada are covered by national public health insurance, the cost of outpatient prescription drugs is not. To solve problems of access, Canadian provinces have introduced provincial prescription drug benefit programs. This study analyzes the prescription drug policymaking process in five Canadian provinces between 1992 and 2004 with a view to (1) determining the federal government's role in the area of prescription drugs; (2) describing the policymaking process; (3) identifying factors in each province's choice of a policy; (4) identifying patterns in those factors across the five provinces; and (5) assessing the federal government's influence on the policies chosen. Analysis shows that despite significant differences in policy choices, the ideological motivations of the provinces were unexpectedly similar. The findings also highlight the importance of institutional factors, for example, in provinces' decision to compete rather than to collaborate. We conclude that, to date, Canada's federalism laboratory has only partly benefited the Canadian public. Cost pressures may, however, eventually overcome barriers to cooperation between the provincial and the federal governments, enabling them to capitalize on Canada's federal structure to improve the accessibility and affordability of drugs.

Priority setting research in health economics has traditionally employed quantitative methodologies and been informed by post-positivist philosophical assumptions about the world and the nature of knowledge. These approaches have been rewarded with well-developed and validated tools. However, it is now commonly noted that there has been limited uptake of economic analysis into actual priority setting and resource allocation decisions made by health-care systems. There seem to be substantial organizational and political barriers. The authors argue in this paper that understanding and addressing these barriers will depend upon the application of qualitative research methodologies. Some efforts in this direction have been attempted; however these are theoretically under-developed and seldom rooted in any of the established qualitative research traditions. Two such approaches - narrative inquiry and discourse analysis - are highlighted here. These are illustrated with examples drawn from a real-world priority setting study. The examples demonstrate how such conceptually powerful qualitative traditions produce distinctive findings that offer unique insight into organizational contexts and decision-maker behavior. We argue that such investigations offer untapped benefits for the study of organizational priority setting and thus should be pursued more frequently by the health economics research community.

OBJECTIVE: The objective of this research was to provide further insights into the ability of Program Budgeting and Marginal Analysis (PBMA) to help health care decision-makers in deciding where to allocate scarce resources so as to best meet their organizational objectives. METHODS: We report on a case study of PBMA implementation. The main source of information was two sets of semi-structured evaluation interviews conducted with senior decision-makers after each of the first two years of PBMA implementation in Vancouver Island Health Authority (VIHA), Canada. These interviews were analysed thematically, with initial coding based upon themes that had been identified in the previous stage of the research. RESULTS: Many of the initial problems with PBMA implementation resolved themselves over time as participants became more familiar with the process. However, some problems needed to be addressed explicitly through changes in procedures. Establishing procedures for handling 'must-dos' (i.e. spending priorities, that are externally mandated) did not replace the need to define explicitly the extent of the organization's discretionary spending authority. CONCLUSION: Faced with claims that typically outstrip available resources, health care decision-makers need a process to guide allocation decisions. PBMA has demonstrated at VIHA an ability to handle some of the key issues associated with this challenge. Our analysis has produced lessons that should facilitate future implementation but has also shown that resource allocation criteria selection and the extent of executive discretion are likely to be ongoing challenges.

BACKGROUND: To date there has been relatively little published about how research priorities are set, and even less about methods by which decision-makers can be engaged in defining a relevant and appropriate research agenda. We report on a recent effort in British Columbia to have researchers and decision-makers jointly establish an agenda for future research into questions of resource allocation. METHODS: The researchers enlisted decision-maker partners from each of British Columbia's six health authorities. Three forums were held, at which researchers and decision-makers from various levels in the health authorities considered possible research areas related to three key focus areas: (1) generation and use of decision criteria and measurement of 'benefit' against such criteria; (2) identification of so-called 'disinvestment' opportunities; and (3) evaluation of the effectiveness of priority setting procedures. Detailed notes were taken from each forum and synthesized into a set of qualitative themes. RESULTS: Forum participants suggested that future research into healthcare priority setting would benefit from studies that were longitudinal, comparative, and/or interdisciplinary. As well, participants identified two broad theme areas in which specific research projects were deemed desirable. First, future research might usefully consider how formal priority setting and resource allocation projects are situated within a larger organizational and political context. Second, additional research efforts should be devoted to better understanding and improving the actual implementation of priority setting frameworks, particularly with respect to issues of change management and the resolution of impediments to action on recommendations for resource allocation. CONCLUSION: We were able to validate the importance of initial areas posed to the group and observed emergence of additional concerns and directions of critical importance to these decision-makers at this time. It is likely that the results are broadly applicable to other healthcare contexts. The implementation of this research agenda in British Columbia will depend upon the ability of the researchers and decision-makers to develop particular projects that fit within the constraints of existing funding opportunities. The process of engagement itself had benefits in terms of connecting decision-makers with their peers and sparking increased interest in the use and refinement of priority setting frameworks.

OBJECTIVE: While much literature has debated public engagement in health care decision-making, there is no consensus on when public engagement should be sought and how it should be obtained. We conducted a scoping review to examine public engagement in one specific area: priority setting and resource allocation. METHOD: The review drew upon a broad range of health and non-health literature in an attempt to elicit what is known and not known on this topic, and through this to outline any guidance to assist decision-makers and identify where efforts for future research should be directed. RESULTS: Governments appear to recognize benefits in consulting multiple publics using a range of methods, though more traditional approaches to engagement continue to predominate. There appears to be growing interest in deliberative approaches to public engagement, which are more commonly on-going rather than one-off and more apt to involve face-to-face contact. However, formal evaluation of public engagement efforts is rare. Also absent is any real effort to demonstrate how public views might be integrated with other decision inputs when allocating social resources. CONCLUSION: While some strands can be taken to inform current priority setting activity, this scoping review identified many gaps and highlights numerous areas for further research.

We argue that public health matters more today than ever because it is uniquely positioned as a meeting point or fulcrum between health care and social welfare policy perspectives on the social determinants of health. It combines a grounding in the sciences of biomedicine and epidemiology with the moral imperatives of social advocacy. Health cannot be delivered through health care policy alone and neither can social welfare policy ensure the well-being of all citizens on its own. Social policy is at a disadvantage because it does not engender universal consent the way health policy can. While the way that illness should be addressed is debated, it should be addressed to be not contested, as is social welfare for vulnerable populations. The convergence of health and social policy to address the social determinants of health means public health advocacy must explicitly leverage biomedicine to provide materialist and substantive arguments and social welfare to provide the normative and moral arguments. We conclude that a new model of public health advocacy or social lobbying is necessary to effectively raise concerns that health care-focused thinking will not, but with potential heft that social welfare, historically, has not been able to command.

BACKGROUND: Decisions regarding the allocation of available resources are a source of growing dissatisfaction for healthcare decision-makers. This dissatisfaction has led to increased interest in research on evidence-based resource allocation processes. An emerging area of interest has been the empirical analysis of the characteristics of existing and desired priority setting processes from the perspective of decision-makers. METHODS: We conducted in-depth, face-to-face interviews with 18 senior managers and medical directors with the Vancouver Island Health Authority, an integrated health care provider in British Columbia responsible for a population of approximately 730,000. Interviews were transcribed and content-analyzed, and major themes and sub-themes were identified and reported. RESULTS: Respondents identified nine key features of a desirable priority setting process: inclusion of baseline assessment, use of best evidence, clarity, consistency, clear and measurable criteria, dissemination of information, fair representation, alignment with the strategic direction and evaluation of results. Existing priority setting processes were found to be lacking on most of these desired features. In addition, respondents identified and explicated several factors that influence resource allocation, including political considerations and organizational culture and capacity. CONCLUSION: This study makes a contribution to a growing body of knowledge which provides the type of contextual evidence that is required if priority setting processes are to be used successfully by health care decision-makers.
RESUMO
This paper reports on expectations for and community members' experience in the development of community indicators in a healthy communities initiative (HCI) in Alberta, Canada. The HCI process involved community visioning, the creation of action plans to further the vision by addressing key health priorities and/or community capacity building activities and the development of indicators to monitor and report on progress towards goals. Nineteen semi-structured interviews were conducted with community participants to discuss definitions of success in the HCI and participant experience in developing indicators. Three themes emerged: the formal indicators lacked relevance to community members; the community did not own the HCI indicators and participants instead drew upon measures of success which were largely experiential in nature. The study provides a critically reflective, candid account of on-the-ground work with communities. The findings reveal limitations in the process of developing community indicators in this HCI, which we attribute in part to skills and discontinuities on the staffing side of the health authority and in part to failure to recognize and fully appreciate 'different ways of knowing' between communities and agencies.
