On the relationship between individual and population health

National Telehealth Contingency Staffing Program and Primary Care Quality in the VHA

Importance

The Veterans Health Administration (VHA) launched the Clinical Resource Hub (CRH), a national telehealth contingency staffing program, to address primary care staffing shortages and improve veteran access to primary care. How this large-scale telehealth intervention affects quality of care is unknown.

Objective

To assess the quality of care for chronic disease management among US veterans receiving high vs low levels of CRH-delivered primary care services and whether racial and ethnic minority veterans experience outcomes similar to those of White veterans when receiving CRH-delivered care.

Design, Setting, and Participants

This retrospective quality improvement study was conducted using VHA administrative data. Veterans receiving primary care services from CRH clinicians between October 1, 2022, to September 30, 2023, were included.

Exposures

Low, medium, and high tertiles of CRH intensity, defined as the proportion of a veteran's CRH primary care visits to their total primary care visits within the study period.

Main Outcomes and Measures

The main outcomes were chronic disease quality measures for 2 common conditions in ambulatory care: diabetes and hypertension. Logistic regression models were used to estimate the association between individual-level receipt of care from a CRH clinician and the study outcomes.

Results

This study included 71 508 veterans (mean [SD] age, 66 [15] years; 91.4% were male). Veterans who received a higher proportion of care from CRH clinicians were more likely to have improved blood pressure control compared with those who received a lower proportion of care. Higher vs lower CRH intensity was associated with improved blood pressure control among veterans with diabetes (79.5% [95% CI, 78.5%-80.4%] vs 76.6% [95% CI, 75.7%-77.5%]) and veterans with hypertension (76.8% [95% CI, 76.0%-77.5%] vs 73.9% [95% CI, 73.2%-74.7%]). Among racial and ethnic minority veterans, no association between CRH intensity and clinical quality was observed.

Conclusions and Relevance

In this large retrospective cohort study among veterans receiving primary care services through a national telehealth contingency staffing program, veterans with a higher proportion of care from CRH clinicians had improvement in blood pressure outcomes. These findings suggest that the CRH program may be helpful in addressing veteran primary care needs without introducing or worsening disparities in ambulatory quality measures among racial and ethnic minority veterans. As health systems face staffing shortages in primary care, these findings can inform strategies for equitable implementation of large-scale telehealth initiatives to fill these gaps and maintain timely access to primary care.

Race as a Risk Marker, Not a Risk Factor: Revising Race-Based Algorithms to Protect Racially Oppressed Patients

Emerging consensus in the medical and public health spheres encourages removing race and ethnicity from algorithms used in clinical decision-making. Although clinical algorithms remain appealing given their promise to lighten the cognitive load of medical practice and save time for providers, they risk exacerbating existing health disparities. Race is a strong risk marker of health outcomes, yet it is not a risk factor. The use of race as a factor in medical algorithms suggests that the effect of race is intrinsic to the patient or that its effects can be distinct or separated from other social and environmental variables. By contrast, incisive public health analysis coupled with a race-conscious perspective recognizes that race serves as a marker of countless other dynamic variables and that structural racism, rather than race, compromises the health of racially oppressed individuals. This perspective offers a historical and theoretical context for the current debates regarding the use of race in clinical algorithms, clinical and epidemiologic perspectives on "risk," and future directions for research and policy interventions that combat color-evasive racism and follow the principles of race-conscious medicine.

A Multigenerational Model of Environmental Risk for Black, Indigenous, and People of Color (BIPOC) Children and Families

BACKGROUND

In recent years, public discourse has increasingly brought institutional and structural racism to the foreground of discussion on the well-being of BIPOC (Black, Indigenous, and People of Color) communities. Environmental toxicity in combination with the social triggers of institutional and structural racism are among the factors that shape the short- and long-term health of BIPOC Americans across multiple lifespans.

OBJECTIVES

We outline a 2 + Generation Model for examining the mechanisms through which institutional and structural racism promotes the intergenerational transmission of environmental health risk and family and interpersonal relationships across the life course and across multiple generations. We present the model's theoretical underpinnings and rationale, discuss model limitations and needed sources of data, and implications for research, policy, and intervention.

DISCUSSION

Parents and children are not only biologically linked in terms of transmission of environmental toxicities, but they are also linked socially and intergenerationally. The 2 + Generation Model foregrounds family and interpersonal relationships occurring within developmental contexts that are influenced by environmental toxicity as well as institutional and structural racism. In sum, the 2 + Generation Model highlights the need for an equity-first interdisciplinary approach to environmental health and redirects the burden of risk reduction away from the individual and onto the institutions and structures that perpetuate the racial disparities in exposure. Doing so requires institutional investment in expanded, multigenerational, and multimethod datasets. https://doi.org/10.1289/EHP13110.

Addressing COVID-19 and Health Literacy Disparities Among Correctional Facility Residents Through Dialogue-Based Education

Carceral communities face heightened COVID-19-related risks while simultaneously experiencing medical mistrust and limited access to health information and services. Health education programs that incorporate dialogue-based, participatory learning models have been shown to motivate health behavior and increase health knowledge in carceral settings. To increase health literacy and change COVID-19-related health behavior among jail residents in the United States, a local health department developed a dialogue-based education program centered around COVID-19 prevention, misinformation, and navigating health care systems. Dialogue-based health information sessions took place in person in a county jail. Pre- and postsurveys gauged the sessions' influence on self-reported health literacy and behavior intention. Overall, 595 residents collectively attended 43 facilitated discussions. Key findings indicate that dialogue-based education can temper medical mistrust, influencing COVID-19 preventive behaviors and increasing health literacy in a carceral setting.

Narratives in exposomics: A reversed heuristic determinism?

Since the completion of the Human Genome Project (HGP), biomedical sciences have moved away from a gene-centred view and towards a multi-factorial one in which environment, broadly speaking, plays a central role in the determination of human health and disease. Environmental exposures have been shown to be highly prevalent in disease causation. They are considered as complementary to genetic factors in the etiology of diseases, hence the introduction of the concept of the "exposome" as encompassing the totality of human environmental exposures, from conception onwards (Wild in Cancer Epidemiol Biomark Prev 14:1847-1850, 2005), and the launch of the Human Exposome Project (HEP) which aims to complement the HGP. At first sight, and seen as complementary to the genome, the exposome could thus appear as contributing to the rise of novel postgenomic deterministic narratives which place the environment at their core. Is this really the case? If so, what sort of determinism is at work in exposomics research? Is it a case of environmental determinism, and if so, in what sense? Or is it a new sort of deterministic view? In this paper, we first show that causal narratives in exposomics are still very similar to gene-centred deterministic narratives. They correspond to a form of Laplacian determinism and, above all, to what Claude Bernard called the "determinism of a phenomenon". Second, we introduce the notion of "reversed heuristic determinism" to characterize the specific deterministic narratives present in exposomics. Indeed, the accepted sorts of external environmental exposures conceived as being at the origins of diseases are determined, methodologically speaking, by their identifiable internal and biological markers. We conclude by highlighting the most relevant implications of the presence of this heuristic determinism in exposomics research.

Frameworks for measuring population health: A scoping review

INTRODUCTION

Many regions in the world are using the population health approach and require a means to measure the health of their population of interest. Population health frameworks provide a theoretical grounding for conceptualization of population health and therefore a logical basis for selection of indicators. The aim of this scoping review was to provide an overview and summary of the characteristics of existing population health frameworks that have been used to conceptualize the measurement of population health.

METHODS

We used the Population, Concept and Context (PCC) framework to define eligibility criteria of frameworks. We were interested in frameworks applicable for general populations, that contained components of measurement of health with or without its antecedents and applied at the population level or used a population health approach. Eligible reports of eligible frameworks should include at least domains and subdomains, purpose, or indicators. We searched 5 databases (Pubmed, EMBASE, Web of Science, NYAM Grey Literature Report, and OpenGrey), governmental and organizational sites on Google and websites of selected organizations using keywords from the PCC framework. Characteristics of the frameworks were summarized descriptively and narratively.

RESULTS

Fifty-seven frameworks were included. The majority originated from the US (46%), Europe (23%) and Canada (19%). Apart from 1 framework developed for rural populations and 2 for indigenous populations, the rest were for general urban populations. The numbers of domains, subdomains and indicators were highly variable. Health status and social determinants of health were the most common domains across all frameworks. Different frameworks had different priorities and therefore focus on different domains.

CONCLUSION

Key domains common across frameworks other than health status were social determinants of health, health behaviours and healthcare system performance. The results in this review serve as a useful resource for governments and healthcare organizations for informing their population health measurement efforts.

A critical exploration of the diets of UK disadvantaged communities to inform food systems transformation: a scoping review of qualitative literature using a social practice theory lens

The UK food system affects social, economic and natural environments and features escalating risk of food insecurity. Yet it should provide access to safe, nutritious, affordable food for all citizens. Disadvantaged UK communities [individuals and families at risk of food and housing insecurity, often culturally diverse] have often been conceptualised in terms of individual behaviour which may lead to findings and conclusions based on the need for individual change. Such communities face public health challenges and are often treated as powerless recipients of dietary and health initiatives or as 'choiceless' consumers within food supply chains. As transforming the UK food system has become a national priority, it is important a diverse range of evidence is used to support understanding of the diets of disadvantaged communities to inform food systems transformation research.A scoping review of UK peer reviewed qualitative literature published in MEDLINE, CINAHL Plus with Full Text, EMBASE, PsycINFO and Web of Science between January 2010 and May 2021 in English. Eligibility criteria were applied, a data extraction table summarised data from included studies, and synthesis using social practice theory was undertaken.Forty-five qualitative studies were reviewed, which included the views of 2,434 community members aged between 5 and 83. Studies used different measures to define disadvantage. Synthesis using social practice theory identified themes of food and dietary practices shaped by interactions between 'material factors' (e.g. transport, housing and money), 'meanings' (e.g. autonomy and independence), and 'competencies' (e.g. strategies to maximise food intake). These concepts are analysed and critiqued in the context of the wider literature to inform food systems transformation research.This review suggests to date, qualitative research into diets of UK disadvantaged communities provides diverse findings that mainly conceptualise disadvantage at an individual level. Whilst several studies provide excellent characterisations of individual experience, links to 'macro' processes such as supply chains are largely missing. Recommendations are made for future research to embrace transdisciplinary perspectives and utilise new tools (e.g., creative methods and good practice guides), and theories (e.g., assemblage) to better facilitate food systems transformation for disadvantaged communities.

Optimizing preconception care and interventions for improved population health

There is growing literature indicating that optimal preconception health is associated with improved reproductive, perinatal, and pediatric outcomes. Given that preconception care is recommended for all individuals planning a pregnancy, medical providers and public health practitioners have a unique opportunity to optimize care and improve health outcomes for reproductive-aged individuals. Knowledge of the determinants of preconception health is important for all types of health professionals, including policy makers. Although some evidence-based recommendations have already been implemented, additional research is needed to identify factors associated with favorable health outcomes and to ensure that effective interventions are made in a timely fashion. Given the largely clinical readership of this journal, this piece is primarily focused on clinical care. However, we acknowledge that optimizing preconception health for the entire population at risk of pregnancy requires broadening our strategies to include population-health interventions that consider the larger social systems, structures, and policies that shape individual health outcomes.

Interventions to address global inequity in diabetes: international progress

Diabetes is a serious chronic disease with high associated burden and disproportionate costs to communities based on socioeconomic, gender, racial, and ethnic status. Addressing the complex challenges of global inequity in diabetes will require intentional efforts to focus on broader social contexts and systems that supersede individual-level interventions. We codify and highlight best practice approaches to achieve equity in diabetes care and outcomes on a global scale. We outline action plans to target diabetes equity on the basis of the recommendations established by The Lancet Commission on Diabetes, organising interventions by their effect on changing the ecosystem, building capacity, or improving the clinical practice environment. We present international examples of how to address diabetes inequity in the real world to show that approaches addressing the individual within a larger social context, in addition to addressing structural inequity, hold the greatest promise for creating sustainable and equitable change that curbs the global diabetes crisis.

Systematic Review of Easy-to-Learn Behavioral Interventions for Dietary Changes Among Young Adults

INTRODUCTION

Improving the diet quality of young adults may support chronic disease prevention. The approaches used and efficacy of promoting small dietary behavior changes through easy-to-learn (ETL) interventions (requiring no more than 1 hour to teach the behavior) among young adults have not yet been systematically reviewed.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 2 independent electronic searches across 6 databases were conducted to identify any articles describing ETL interventions among young adults (aged 18-35 years) and reporting dietary intake outcomes.

RESULTS

Among 9,538 articles identified, 9 studies met eligibility criteria. Five studies reported significant improvement in the selected dietary outcome. Of these, 3 studies used an implementation intentions approach, in which participants were given or asked to write out a simple dietary behavior directive and carry it on their person. Less than half of included studies were rated as positive for overall quality.

DISCUSSION

The available evidence suggests that ETL interventions targeting the dietary behaviors of young adults may be effective in improving dietary intake. Limitations of included studies were lack of follow-up after the intervention period and low generalizability.

IMPLICATIONS FOR RESEARCH AND PRACTICE

Further dietary intervention studies targeting young adults should systematically evaluate the efficacy of ETL intervention approaches among diverse samples.

Body social models of disability: Examining enactive and ecological approaches

Autistic philosopher and neurodiversity proponent Robert Chapman (2021) argues that disability may be best understood by utilizing an ecological functional model where the focus is on the intersection and overlaps between relational contributions to collectives and group functioning with individual functionality. This presents an alternative to both social-relational models of disability advocated by other neurodiversity proponents and the orthodox medical model of disability. While enactivists such as Michelle Maiese and Juan Toro, Julian Kiverstein and Erik Rietveld have also offered relational models of disability that challenge the orthodox medical model, I argue that unlike the ecological functional model, these enactivist models remain problematically committed to an individualist methodology. Drawing on what Miriam Kyselo has labeled the body social problem, I show that the enactivist models not only face theoretical issues, but also practical issues in terms of their recommended intervention strategies for disability. I argue that for these reasons, if enactivists want a relational model of disability, then they should adopt both a neurodiversity paradigm approach and Chapman’s ecological functional model.

The Value of New: Consideration of Product Novelty in Health Technology Assessments of Pharmaceuticals

BACKGROUND

Efforts to understand how treatments affect patients and society have broadened the criteria that health technology assessment (HTA) organizations apply to value assessments. We examined whether HTA agencies in eight countries consider treatment novelty in methods and deliberations.

METHODS

We defined a novel pharmaceutical product to be one that offers a new approach to treatment (e.g., new mechanism of action), addresses an unmet need (e.g., targets a rare condition without effective treatments), or has a broader impact beyond what is typically measured in an HTA. We reviewed peer-reviewed publications and technical guidance materials from HTA organizations in Australia, Canada, England, France, The Netherlands, Norway, Sweden, and the United States (US). In addition, we explored how HTA organizations integrated novelty considerations into deliberations and recommendations related to two newer therapies-voretigene neparvovec for an inherited retinal disorder and ocrelizumab for multiple sclerosis.

RESULTS

None of the HTA organizations acknowledge treatment novelty as an explicit value criterion in their assessments of pharmaceutical products. However, drugs that have novel characteristics are given special consideration, particularly when they address an unmet need. Several organizations document a willingness to expend more resources and accept greater evidence uncertainty for such treatments. Qualitative deliberations about the additional unquantified potential benefits of treatment may also influence HTA recommendations.

CONCLUSION

Major HTA organizations do not recognize novelty as an explicit value criterion, although drugs with novel characteristics may receive special consideration. There is an opportunity for organizations to codify their approach to evaluating novelty in value assessment.

Formation and Preservation of Students’ Mental Health in the Process of Studying at Pedagogical Universities

Aim: The aim is to experimentally verify the methodology of self-regulation culture formation as an important element of professional training of future teachers of the humanities in the process of studying the author’s specialized course referred to as “Fundamentals of Psychovaleology”. Materials and Methods: The research involved third-year students of pedagogical institutions of higher education aged 20 to 23 years in the number of 126 people (80 girls and 46 boys). The methods used included observation, questionnaires, psychodiagnostic methods for determining the level of anxiety, self-assessment of well-being, quantitative and qualitative analysis of the results in terms of self-regulation culture formation according to theoretical, practical and professional criteria. Results: Experimental verification of the effectiveness of the developed methodology shows qualitative positive changes in the students’ emotional well-being, in significant reduction of their anxiety, as well as in increasing motivation for active exercise Conclusions: The developed methodology of self-regulation culture formation in future teachers can become a significant basis for the further formation of individual health preservation competence of students i. e. future teachers, their orientation to active physical education as well as fitness and health recreation activities, and can also be included in the system of implementation of professional standards for the training of students in pedagogical specialties, especially in terms of the development of their health preservation competence

THE RIGHT TO HEALTH CARE IN THE CONTEXT OF PUBLIC AND PRIVATE INTERESTS

OBJECTIVE

The aim: To review of existing approaches regarding the ratio of private and public interests in the content of the right to health care.

PATIENTS AND METHODS

Materials and methods: In this paper, a systemic approach was used, which made it possible to analyze public-law and private-law interests as part of the content of the right to health care in their systemic unity. The application of the comparative research method and the dialectical method made it possible to investigate the dynamic relationship between public legal and private legal interests as part of the right to health care.

CONCLUSION

Conclusions: In the context of the analysis of the content of the right to health care, it was determined that private and public interests find their form in the institutions of individual and public health. In conditions of economic stability and the absence of threats to the realization of the right to health care, the state of realization of the right to individual health and public health can be described by the categories of «binary» or «synergy», when public health and individual health strengthen each other one. Private and public interests in the content of the right to health care can be in a state of conflict in conditions of limited resources. Taking into account the need to legitimately regulate the conflict between private and public interests in the content of the right to health care, states establish legal norms, which we defined as «axiological collisions».

Merging the exposome into an integrated framework for "omics" sciences

The exposome concept encourages holistic consideration of the non-genetic factors (environmental exposures including lifestyle) that influence an individual's health over their life course. However, disconnect between the concept and practical application has promoted divergent interpretations of the exposome across disciplines and reinforced separation of the environmental (emphasizing exposures) and biological (emphasizing responses) research communities. In particular, while knowledge of biological responses can help to distinguish actual (i.e. experienced) from potential exposures, the inclusion of endogenous processes has generated confusion about the position of the exposome in a multi-omics systems biology context. We propose a reattribution of "exposome" to exclusively represent the totality of contact with external factors that a biological entity experiences, and introduce the term "functional exposomics" to denote the systematic study of exposure-phenotype interaction. This reoriented definition of the exposome allows a more readily integrable dataset for multi-omics and systems biology research.

Can populations be healthy? Perspectives from Georges Canguilhem and Geoffrey Rose

Canguilhem criticized the concept of "public health": health and disease are concepts that only apply to individuals, taken as organic totalities. Their extension to a different level of organization is purely metaphorical. The importance assumed by epidemiology in the construction of our knowledge of the normal and the pathological does, however, call for reflection on the role and the status of the population level of organization in our approach to health phenomena. The entanglement of the biological and the social in human life and in contemporary societies justifies this level of analysis for better understanding the complexity and the interaction of health determinants both at the level of individuals and their interactions and at that of the population. But is this population level just a useful level of analysis that makes it possible to bring to light the social determinants of health at the individual level, or does it rest instead on characteristics of the population that are irreducible to individual characteristics, but which are nevertheless important for understanding and taking action with respect to both population and individual health? Defending this second alternative, I show how the epidemiological point of view, and in particular that of social epidemiology, leads us to rethink the possibility of a concept of "population health" that is not reducible to the sum of individual instances of health.

Quantification of Occupational and Community Risk Factors for SARS-CoV-2 Seropositivity Among Health Care Workers in a Large U.S. Health Care System

BACKGROUND

Identifying occupational risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among health care workers (HCWs) can improve HCW and patient safety.

OBJECTIVE

To quantify demographic, occupational, and community risk factors for SARS-CoV-2 seropositivity among HCWs in a large health care system.

DESIGN

A logistic regression model was fitted to data from a cross-sectional survey conducted in April to June 2020, linking risk factors for occupational and community exposure to coronavirus disease 2019 (COVID-19) with SARS-CoV-2 seropositivity.

SETTING

A large academic health care system in the Atlanta, Georgia, metropolitan area.

PARTICIPANTS

Employees and medical staff members elected to participate in SARS-CoV-2 serology testing offered to all HCWs as part of a quality initiative and completed a survey on exposure to COVID-19 and use of personal protective equipment.

MEASUREMENTS

Demographic risk factors for COVID-19, residential ZIP code incidence of COVID-19, occupational exposure to HCWs or patients who tested positive on polymerase chain reaction test, and use of personal protective equipment as potential risk factors for infection. The outcome was SARS-CoV-2 seropositivity.

RESULTS

Adjusted SARS-CoV-2 seropositivity was estimated to be 3.8% (95% CI, 3.4% to 4.3%) (positive, n = 582) among the 10 275 HCWs (35% of the Emory Healthcare workforce) who participated in the survey. Community contact with a person known or suspected to have COVID-19 (adjusted odds ratio [aOR], 1.9 [CI, 1.4 to 2.6]; 77 positive persons [10.3%]) and community COVID-19 incidence (aOR, 1.5 [CI, 1.0 to 2.2]) increased the odds of infection. Black individuals were at high risk (aOR, 2.1 [CI, 1.7 to 2.6]; 238 positive persons [8.3%]).

LIMITATIONS

Participation rates were modest and key workplace exposures, including job and infection prevention practices, changed rapidly in the early phases of the pandemic.

CONCLUSION

Demographic and community risk factors, including contact with a COVID-19-positive person and Black race, are more strongly associated with SARS-CoV-2 seropositivity among HCWs than is exposure in the workplace.

Neurodiversity and the Social Ecology of Mental Functions

In psychiatry, mental dysfunction is typically framed in relation to models that seek to be continuous with physiology or evolutionary biology and that compare individual fitness to a broader functional norm. Proponents of the neurodiversity movement, however, challenge the pathologization of minority cognitive styles and argue that we should reframe neurocognitive diversity as a normal and healthy manifestation of biodiversity. Neurodiversity proponents have thus far drawn on social-relational models of disability to challenge the medical model of disability, but they have not developed an alternative functional analysis to replace conceptions of neurological dysfunction or impairment. Here I clarify and defend the neurodiversity perspective by drawing on ecological functional models that take relational contributions to collectives, and group functioning, into account alongside individual functionality. Using the example of autism as well as recent developments in the study of cognitive diversity, I apply these models to human mental functioning and argue that what I call the ecological model has greater utility for research and practice than the leading psychiatric functional analyses of mental functioning.

Quantification of occupational and community risk factors for SARS-CoV-2 seropositivity among healthcare workers in a large U.S. healthcare system

BACKGROUND

Quantifying occupational risk factors for SARS-CoV-2 infection among healthcare workers can inform efforts to improve healthcare worker and patient safety and reduce transmission. This study aimed to quantify demographic, occupational, and community risk factors for SARS-CoV-2 seropositivity among healthcare workers in a large metropolitan healthcare system.

METHODS

We analyzed data from a cross-sectional survey conducted from April through June of 2020 linking risk factors for occupational and community exposure to COVID-19 with SARS-CoV-2 seropositivity. A multivariable logistic regression model was fit to quantify risk factors for infection. Participants were employees and medical staff members who elected to participate in SARS-CoV-2 serology testing offered to all healthcare workers as part of a quality initiative, and who completed a survey on exposure to COVID-19 and use of personal protective equipment. Exposures of interest included known demographic risk factors for COVID-19, residential zip code incidence of COVID-19, occupational exposure to PCR test-positive healthcare workers or patients, and use of personal protective equipment. The primary outcome of interest was SARS-CoV-2 seropositivity.

RESULTS

SARS-CoV-2 seropositivity was estimated to be 5.7% (95% CI: 5.2%-6.1%) among 10,275 healthcare workers. Community contact with a person known or suspected to have COVID-19 (aOR=1.9, 95% CI:1.4-2.5) and zip code level COVID-19 incidence (aOR: 1.4, 95% CI: 1.0-2.0) increased the odds of infection. Black individuals were at high risk (aOR=2.0, 95% CI:1.6-2.4). Overall, occupational risk factors accounted for 27% (95% CI: 25%-30%) of the risk among healthcare workers and included contact with a PCR test-positive healthcare worker (aOR=1.2, 95% CI:1.0-1.6).

CONCLUSIONS

Community risk factors, including contact with a COVID-19 positive individual and residential COVID-19 incidence, are more strongly associated with SARS-CoV-2 seropositivity among healthcare workers than exposure in the workplace.

Dying individuals and suffering populations: applying a population-level bioethics lens to palliative care in humanitarian contexts: before, during and after the COVID-19 pandemic

BACKGROUND

Humanitarian crises and emergencies, events often marked by high mortality, have until recently excluded palliative care-a specialty focusing on supporting people with serious or terminal illness or those nearing death. In the COVID-19 pandemic, palliative care has received unprecedented levels of societal attention. Unfortunately, this has not been enough to prevent patients dying alone, relatives not being able to say goodbye and palliative care being used instead of intensive care due to resource limitations. Yet global guidance was available. In 2018, the WHO released a guide on 'Integrating palliative care and symptom relief into the response to humanitarian emergencies and crises'-the first guidance on the topic by an international body.

AIMS

This paper argues that while a landmark document, the WHO guide took a narrowly clinical bioethics perspective and missed crucial moral dilemmas. We argue for adding a population-level bioethics lens, which draws forth complex moral dilemmas arising from the fact that groups having differential innate and acquired resources in the context of social and historical determinants of health. We discuss dilemmas concerning: limitations of material and human resources; patient prioritisation; euthanasia; and legacy inequalities, discrimination and power imbalances.

IMPLICATIONS

In parts of the world where opportunity for preparation still exists, and as countries emerge from COVID-19, planners must consider care for the dying. Immediate steps to support better resolutions to ethical dilemmas of the provision of palliative care in humanitarian and emergency contexts will require honest debate; concerted research effort; and international, national and local ethical guidance.

Invited Commentary: Making Causal Inference More Social and (Social) Epidemiology More Causal

A society's social structure and the interactions of its members determine when key drivers of health occur, for how long they last, and how they operate. Yet, it has been unclear whether causal inference methods can help us find meaningful interventions on these fundamental social drivers of health. Galea and Hernán propose we place hypothetical interventions on a spectrum and estimate their effects by emulating trials, either through individual-level data analysis or systems science modeling (Am J Epidemiol. 2020;189(3):167-170). In this commentary, by way of example in health disparities research, we probe this "closer engagement of social epidemiology with formal causal inference approaches." The formidable, but not insurmountable, tensions call for causal reasoning and effect estimation in social epidemiology that should always be enveloped by a thorough understanding of how systems and the social exposome shape risk factor and health distributions. We argue that one way toward progress is a true partnership of social epidemiology and causal inference with bilateral feedback aimed at integrating social epidemiologic theory, causal identification and modeling methods, systems thinking, and improved study design and data. To produce consequential work, we must make social epidemiology more causal and causal inference more social.

Structural Factors Responsible for Universal Health Coverage in Low- and Middle-Income Countries: Results From 118 Countries

Background: Demography, politics, economy, and governance appear to be the major structural factors for health and well-being. These factors have a significant role to play in achieving universal health coverage (UHC). The majority of previous studies did not highlight those factors. The aim of this study is to explore the basic structural factors (political stability, demography, gross national income, governance, and transparency) associated with a UHC index of low- and middle-income countries because for a long time there has be a stagnation achieving universal health coverage. Methodology: This study was a cross-sectional study applying multiple indices as variables. Low- and middle-income countries' selected indicators were the study variables. Data concerned the current political stability, sociodemographic status, gross national income (GNI), and governance status as independent variables and the UHC index of the countries as the dependent variable. Mean and standard deviations were used for the average values of the variables, a raw correlation was shown among variables and a hierarchical linear regression model was used for multi variate analysis. Results: Government health expenditure is 6% out of the total budget in upper middle countries (UMIC) and ~5% in lower middle countries (LMIC) and low-income countries (LIC), population below poverty line is more than 2-fold higher in LIC in comparison with high income countries, UHC index, and socio-demographic index (SDI) index is similar in LMIC and LIC and slightly higher in UMIC. There is a positive association between government health expenditure, governance index, stability index, the SDI index, and GNI per capita and a negative association between populations below poverty line with UHC index. According to our full regression analysis model, governance, stability, and SDI index were associated with a significantly increased UHC index by 0.33, 0.41, and 0.57 (p < 0.05). Conclusion: To achieve UHC, good governance, political stability, and demographic balance are prerequisites and addressing these factors would help to meet by 2030 across countries.

Is Fisheries and Oceans Canada policy receptive to a new Pacific salmon health perspective?

The concept of health permeates priorities and policies for managing wild Pacific salmon ( Oncorynchus spp.). Regulatory agencies rely largely on salmon abundance and (or) the absence of pathogens to declare if a population is healthy. Our goal was to determine if there was a receptive policy environment within Fisheries and Oceans Canada (DFO) to adopt a cumulative effects perspective of health. We used a previously developed health model along with a multiple streams framework and a narrative review of DFO policy to see how fish health was situated in DFO’s salmon management problems, policy, and politics. We discovered that a cumulative effects perspective was consistent with policy goals and priorities. DFO’s guiding principles and responsibilities for aquatic animal health were spread across multiple policies and regulations. There were no processes or people responsible for integrating information and activities. The use of the word health in policies and planning without a consistent definition meant that DFO could not explicitly assess if it has reached its management target of healthy salmon. An option for transitioning to cumulative effects perspective is to adopt a healthy public policy perspective and processes to integrate the diverse information linked to social and environmental determinants of health.

Cancer prevention and screening: the next step in the era of precision medicine

A primary mode of cancer prevention and early detection in the United States is the widespread practice of screening. Although many strategies for early detection and prevention are available, adverse outcomes, such as overdiagnosis and overtreatment, are prevalent among those utilizing these approaches. Broad use of mammography and prostate cancer screening are key examples illustrating the potential harms stemming from the detection of indolent lesions and the subsequent overtreatment. Furthermore, there are several cancers for which prevention strategies do not currently exist. Clinical and experimental evidence have expanded our understanding of cancer initiation and progression, and have instructed the development of improved, precise modes of cancer prevention and early detection. Recent cancer prevention and early detection innovations have begun moving towards the integration of molecular knowledge and risk stratification profiles to allow for a more accurate representation of at-risk individuals. The future of cancer prevention and early detection efforts should emphasize the incorporation of precision cancer prevention integration where screening and cancer prevention regimens can be matched to one's risk of cancer due to known genomic and environmental factors.

A DETERMINANTS OF HEALTH CONCEPTUAL MODEL FOR FISH AND WILDLIFE HEALTH

Our objectives were to establish if the determinant of health model used in the fields of human population and public health could be adapted to wildlife health; if it was applicable to more than one species; and if it reflected how fish and wildlife managers conceptualized health in practice. A conceptual model was developed using a scoping review on fish and wildlife health and resilience coupled with a participatory process with experts on barren ground caribou ( Rangifer tarandus groenlandicus) and sockeye salmon ( Oncorhynchus nerka) health. Both the literature and experts supported the concept of wildlife health as a cumulative effect involving multiple factors that extend beyond the disease and pathogen focus of many wildlife health studies and legislation. Six themes were associated with fish and wildlife health: 1) the biologic endowment of the individual and population; 2) the animal's social environment; 3) the quality and abundance of the animal's needs for daily living; 4) the abiotic environment in which the animal lives; 5) sources of direct mortality; and 6) changing human expectations. These themes were shared between salmon and caribou and conformed to expert perceptions of health. Determinants of health used in human public health are used for planning, development of policy, and guiding of research. The model we produced may also have use as a wildlife health planning tool to help managers identify health protection priorities and to promote actions across the determinants of health.

Cannabis Legalization in Canada: Reflections on Public Health and the Governance of Legal Psychoactive Substances

The Canadian government is "taking a public health approach to legalizing, strictly regulating and restricting access to cannabis." There is, however, no universally accepted definition of a public health approach to cannabis. This paper presents what such an approach is, and is not, and discusses its applicability to legal psychoactive substances more generally. It critically reflects on the role of the public health sector in the governance of addictive substances and activities, noting its function of "responsibilizing" individuals and coaxing them to self-regulate-and the contradiction involved when other state actors involved in governance are actively inciting consumption of those substances and activities.

A Snapshot of Community Engagement in Research in the Context of an Evolving Public Health Paradigm: Review

BACKGROUND

Community engagement is a work in process. Researchers continue to refine the process of collaboration and look to best practice and lessons learned for guidance in this relatively new model.

OBJECTIVE

The aim of this study was to provide a snapshot of whether community engagement has been included in the design and implementation of research initiatives in Australia, Canada and the United Kingdom. The secondary aim is to identify the underlying themes present, to identify theories and tools that drive research.

METHODS

A literature search was performed to identify studies that have been conducted to reduce the weight of the general population.

RESULTS

The results of the study, which focused on the field of weight loss, indicate that scientific and technological advancements are the primary drivers of research. However, these new research initiatives have largely been undertaken in the absence of community engagement.

CONCLUSIONS

The study concludes that initiatives need to adapt to a wider range of stakeholders, develop equitable community engagement platforms and take into consideration.

The impact of human development on individual health: a causal mediation analysis examining pathways through education and body mass index

BACKGROUND

The macro environment we live in projects what we can achieve and how we behave, and in turn, shapes our health in complex ways. Policymaking will benefit from insights into the mechanisms underlying how national socioeconomic context affects health. This study examined the impact of human development on individual health and the possible mediating roles of education and body mass index (BMI).

METHODS

We analyzed World Health Survey data on 109,448 participants aged 25 or older from 42 low- and middle-income countries with augmented human development index (HDI) in 1990. We used principal components method to create a health score based on measures from eight health state domains, used years of schooling as education indicator and calculated BMI from self-reported height and weight. We used causal mediation analysis technique with random intercepts to account for the multilevel structure.

RESULTS

Below a reference HDI level of 0.48, HDI was negatively associated with good health (total effect at HDI of 0.23: b =  - 3.44, 95% CI [-6.39--0.49] for males and b =  - 5.16, 95% CI [-9.24,--1.08] for females) but was positively associated with good health above this reference level (total effect at HDI of 0.75: b = 4.16, 95% CI [-0.33-8.66] for males and b = 6.62, 95% CI [0.85-12.38] for females). We found a small positive effect of HDI on health via education across reference HDI levels (b ranging from 0.24 to 0.29 for males and 0.40 to 0.49 for females) but not via pathways involving BMI only.

CONCLUSION

Human development has a non-linear effect on individual health, but the impact appears to be mainly through pathways other than education and BMI.

Measuring renewed expertise for integrated care among health- and social-care professionals: Development and preliminary validation of the ICE-Q questionnaire

Accumulations of health and social problems challenge current health systems. It is hypothesized that professionals should renew their expertise by adapting generalist, coaching, and population health orientation capacities to address these challenges. This study aimed to develop and validate an instrument for evaluating this renewal of professional expertise. The (Dutch) Integrated Care Expertise Questionnaire (ICE-Q) was developed and piloted. Psychometric analysis evaluated item, criterion, construct, and content validity. Theory and an iterative process of expert consultation constructed the ICE-Q, which was sent to 616 professionals, of whom 294 participated in the pilot (47.7%). Factor analysis (FA) identified six areas of expertise: holistic attitude towards patients (Cronbach's alpha [CA] = 0.61) and considering their social context (CA = 0.77), both related to generalism; coaching to support patient empowerment (CA = 0.66); preventive action (CA = 0.48); valuing local health knowledge (CA = 0.81); and valuing local facility knowledge (CA = 0.67) point at population health orientation. Inter-scale correlations ranged between 0.01 and 0.34. Item-response theory (IRT) indicated some items were less informative. The resulting 26-item questionnaire is a first tool for measuring integrated care expertise. The study process led to a developed understanding of the concept. Further research is warranted to improve the questionnaire.

Implications of health as 'the ability to adapt and self-manage' for public health policy: a qualitative study

BACKGROUND

To explore the implications for public health policy of a new conceptualisation of health as 'The ability to adapt and to self-manage, in the face of social, physical and emotional challenges'.

METHODS

Secondary qualitative data analysis of 28 focus group interviews, with 277 participants involved in public health and healthcare, on the future of the Dutch healthcare system. WHO's essential public health operations (EPHOs) were used as a framework for analysis.

RESULTS

Starting from the new concept of health, participants perceived health as an individual asset, requiring an active approach in the Dutch population towards health promotion and adaptation to a healthy lifestyle. Sectors outside healthcare and public health were considered as resources to support individual lifestyle improvement. Integrating prevention and health promotion in healthcare is also expected to stimulate individuals to comply with a healthy lifestyle. Attention should be paid to persons less skilled to self-manage their own health, as this group may require a healthcare safety net. The relationship between individual and population health was not addressed, resulting in little focus on collective prevention to achieve health.

CONCLUSIONS

The new concept of health as a basis for changes in the healthcare system offers opportunities to create a health-promoting societal context. However, inequalities in health within the general population may increase when using the new concept as an operationalisation of health. For public health, the main challenge is to maintain focus on the collective socioeconomic and environmental determinants of health and disease and, thereby, preserve collective prevention.

Global educational disparities in the associations between body mass index and diabetes mellitus in 49 low-income and middle-income countries

BACKGROUND

Despite the well-established link between body mass index (BMI) and diabetes mellitus (DM), it remains unclear whether this association is more pronounced at certain levels of education. This study assessed the modifying effect of educational attainment on the associations between BMI and DM-as well as the joint associations of BMI and education with DM-in low-income countries (LICs) and middle-income countries (MICs).

METHODS

The authors used cross-sectional data from 160 381 participants among 49 LICs and MICs in the World Health Survey. Overweight and obesity levels were defined using WHO's classification. Educational attainment was classified in four categories: 'no formal education', 'some/completed primary school', 'secondary/high school completed' and 'college and beyond'. We used random-intercept multilevel logistic regressions to investigate the modifying influence of educational attainment on the associations of different BMI levels-as well as their joint associations-with DM.

RESULTS

We found positive associations between excessive BMI and DM at each education level in both LICs and MICs. We found that the joint associations of BMI and education with DM were larger than the product of their separate single associations among females in LICs. With joint increases in BMI and education, males and females in LICs had similar increased odds of DM, but males had higher such odds than females in MICs.

CONCLUSIONS

BMI and education are associated with the DM, but the associations seem to differ in complex ways between LICs and MICs and by gender.

[Effective coverage to manage domestic violence against women in Mexican municipalities: limits of metrics]

The study estimated the effective coverage of health services in primary care for the management of domestic violence against women in three municipalities in Mexico. We estimated the prevalence and severity of violence using a validated scale, and the effective coverage proposed by Shengelia and partners with any modifications. Quality care was considered when there was a suggestion to report it to authorities. The use and quality of care was low in the three municipalities analyzed, used most frequently when there was sexual or physical violence. Effective coverage was 29.41%, 16.67% and zero in Guachochi, Jojutla and Tizimín, respectively. The effective coverage indicator had difficulties in measuring events and responses that were not based on biomedical models. Findings suggest that the indicator can be improved by incorporating other dimensions of quality.

The modifying influence of country development on the effect of individual educational attainment on self-rated health

OBJECTIVES

We investigated how much the Human Development Index (HDI), a global measure of development, modifies the effect of education on self-reported health.

METHODS

We analyzed cross-sectional World Health Survey data on 217,642 individuals from 49 countries, collected in 2002 to 2005, with random-intercept multilevel linear regression models.

RESULTS

We observed greater positive associations between educational levels and self-reported good health with increasing HDI. The magnitude of this effect modification of the education-health relation tended to increase with educational attainment. For example, before adjustment for effect modification, at comparable HDI, on average, finishing primary school was associated with better general health (b = 1.49; 95% confidence interval [CI] = 1.18, 1.80). With adjustment for effect modification by HDI, the impact became 4.63 (95% CI = 3.63, 5.62) for every 0.1 increase in HDI. Among those who completed high school, these associations were, respectively, 5.59 (95% CI = 5.20, 5.98) and 9.95 (95% CI = 8.89, 11.00).

CONCLUSIONS

The health benefits of educational attainment are greater in countries with greater human development. Health inequalities attributable to education are, therefore, larger in more developed countries.

Time series analysis of maternal mortality in Africa from 1990 to 2005

OBJECTIVES

Most global maternal deaths occur in Africa and Asia. In response, the Millennium Development Goal (MDG-5) calls for a 75% reduction in maternal mortality from 1990 to 2015. To assess the potential for progress in MDG-5 in Africa, we examined the cross-sectional and longitudinal associations of socioeconomic, demographic and population-health factors with maternal mortality rates in Africa.

METHODS

We used data from global agencies and the published literature to identify socioeconomic, demographic and population-health explanatory factors that could be correlated with maternal mortality in 49 countries of Africa for the years 1990, 1995, 2000 and 2005. We used correlation, negative binomial and mixed Poisson regression models to investigate whether there exist associations between potential explanatory factors and maternal mortality.

RESULTS

Some African countries have made substantial progress towards achieving MDG-5 while others have fallen behind. Lower gross domestic product (GDP) and female enrolment in primary schools, but higher HIV prevalence, neonatal mortality rate and total fertility rate, were associated with higher maternal mortality.

CONCLUSIONS

Maternal mortality rates in African countries appear to be declining. The mean maternal mortality ratios in Africa decreased from 695.82 in 1990 to 562.18 in 2005. Yet some countries are more likely than others to achieve MDG-5. Better socioeconomic, demographic and population health development appear to be conducive to better maternal health in Africa. Sustained efforts on all these fronts will be needed to close the gap in maternal survival and achieve MDG-5 in Africa.

Adherence by Dutch public health nurses to the national guidelines for tuberculosis contact investigation

Objectives

To assess whether public health nurses adhered to Dutch guidelines for tuberculosis contact investigations and to explore which factors influenced the process of identifying contacts, prioritizing contacts for testing and scaling up a contact investigation.

Methods

A multiple-case study (2010–2012) compared the contact investigation guidelines as recommended with their use in practice. We interviewed twice 14 public health nurses of seven Public Health Services while they conducted a contact investigation.

Results

We found more individuals to be identified as contacts than recommended, owing to a desire to gain insight into the infectiousness of the index case and prevent anxiety among potential contacts. Because some public health nurses did not believe the recommendations for prioritizing contacts fully encompassed daily practice, they preferred their own regular routine. In scaling up a contact investigation, they hardly applied the stone-in-the-pond principle. They neither regularly compared the infection prevalence in the contact investigation with the background prevalence in the community, especially not in immigrant populations. Nonadherence was related to ambiguity of the recommendations and a tendency to act from an individual health-care position rather than a population health perspective.

Conclusions

The adherence to the contact investigation guidelines was limited, restraining the effectiveness, efficiency and uniformity of tuberculosis control. Adherence could be optimized by specifying guideline recommendations, actively involving the TB workforce, and training public health nurses.
