Challenges to an integrated population health research agenda: Targets, scale, tradeoffs and timing

Building the evidence on Making Health a Shared Value: Insights and considerations for research

The Robert Wood Johnson Foundation (RWJF)'s Culture of Health Action Framework guides a movement to improve health and advance health equity across the nation. Action Area One of the Framework, Making Health a Shared Value, highlights the role of individual and community factors in achieving a societal commitment to health and health equity, centered around three drivers: Mindset and Expectations, Sense of Community, and Civic Engagement. To stimulate research about how Action Area One and its drivers may impact health, Evidence for Action (E4A), a signature research funding program of RWJF, developed and released a national Call for Proposals (CFP). The process of formulating the CFP and reviewing proposals surfaced important challenges for research on creating and sustaining shared values to foster and maintain a Culture of Health. In this essay, we describe these considerations and provide examples from funded projects regarding how challenges can be addressed.

Learning from elsewhere: Integrated care development in Singapore

The Singapore healthcare sector faces a myriad of challenges, including a rapidly ageing population, an increasing burden of chronic disease, and the rising cost of healthcare. The Ministry of Health has called for a restructuring and transformation of the current model of care to one that is more accessible, affordable and of higher quality, by the year 2020. In achieving quality health care, care integration through the Regional Health Systems (RHS) is seen as one approach to improving health and social outcomes, increasing healthcare utilisation and increasing satisfaction with healthcare providers. We conducted a qualitative study involving 31 elites from five policy agent clusters, and analysed organisational documents, to explore how the concepts of policy transfer and policy translation, explain the ways in which integrated care was introduced and developed in Singapore, with a focus on the SingHealth (SGH Campus) Regional Health System (RHS). The findings demonstrate that the development of integrated care is mediated by multi-scalar and multi-site networks and contextual features. The multiple and pluralistic interpretations of 'integrated care' and 'policy' are contested spaces or domains requiring further negotiation and debate. Institutional issues in the SingHealth (SGH Campus) RHS, and in the private and ILTC sectors highlight the need to consider spatial and temporal factors, and the multiplexities in the embedding of integrated care policy.

Perceived neighborhood disorder, racial-ethnic discrimination and leading risk factors for chronic disease among women: California Behavioral Risk Factor Surveillance System, 2013

Social environmental factors are theoretically identified as influential drivers of health behaviors – tobacco smoking, alcohol consumption, and physical activity – related to chronic disease disparities. Empirical studies investigating relationships involving social environmental factors have found that either greater interpersonal racial-ethnic discrimination or perceived neighborhood disorder were associated with adverse health behaviors, with potentially larger effects among women. We simultaneously tested whether measures of perceived racial-ethnic discrimination and perceived neighborhood disorder were associated with physical activity, alcohol consumption and tobacco smoking; lifestyle risk factors of major chronic disease among women. Data were from the 2013 California Behavioral Risk Factor Surveillance System. In addition to demographic and socioeconomic factors, women self-reported experiences with racial-ethnic discrimination and perception of neighborhood disorder (i.e., crime safety, traffic safety, and aesthetics/physical disorder). Survey-, and inverse probability of censoring-weighted regression models of each chronic disease risk factor were used to investigate associations involving racial-ethnic discrimination and neighborhood disorder, controlling for potential confounders. Perceiving racial-ethnic discrimination and greater neighborhood disorder were associated with a greater tobacco smoking prevalence. Experiences of racial-ethnic discrimination were associated with greater alcohol consumption among African American and Latino women, but not White women. Similarly, African American women reporting experiences with racial-ethnic discrimination report engaging in physical activity about half as much time as women reporting no racial-ethnic discrimination. Increases in perceived neighborhood disorder were associated with increases in alcohol consumption. All associations with social environmental factors were adjusted for potential confounders and each other. Neighborhood disorder and racial-ethnic discrimination may be important, independent contributors to chronic disease risk through relationships with tobacco smoking, alcohol consumption, and physical activity.

Spillovers between siblings and from offspring to parents are understudied: A review and future directions for research

BACKGROUND

While a large literature has highlighted the protective effects of human capital on an individual's health and to some extent their offspring's health, little evidence is available on the positive spillover benefits of human capital for other family members. We conducted a scoping review of the evidence and identify future directions for research.

METHODS

We systematically searched the public health and economics literature on spillover effects from human capital, as indicated by educational attainment, to the health and/or survival of family members. We assessed (i) downward spillover effects (from parents and/or grandparents to offspring), (ii) horizontal spillover effects (from partners, spouses, and/or siblings), and (iii) upward spillover effects (from offspring to their parents and/or grandparents). We assessed the frequency of studies, their study designs, findings, and identified priority areas to inform future research on spillover effects of human capital.

FINDINGS

A total of 567 studies met our selection criteria. 286 studies assessed downward spillovers, 22 studies assessed horizontal spillovers, and five studies assessed upward spillovers. Studies on horizontal and upward spillovers found universally positive associations between additional education and better health in family members. The majority of studies used cross-sectional and longitudinal study designs as opposed to (quasi-)experimental designs. Further research is needed on horizontal and upward spillovers and research in low-resource settings, in addition to understanding what level of education matters the most, as well as mechanisms.

CONCLUSIONS

Although positive spillovers of human capital between siblings and from offspring to parents are likely, they have been understudied. Estimates of the returns to human capital that exclude these benefits may be too low.

Considering disparities: How do nurse practitioner regulatory policies, access to care, and health outcomes vary across four states?

BACKGROUND

Health disparities persist among morbidity and mortality rates in the United States. Contributing significantly to these disparities are the ability to pay for health care (largely, access to health insurance) and access to, and capacity of, the primary care health workforce.

PURPOSE

This article examines key determinants of health (DOH) including demographics, public and regulatory policies, health workforce capacity, and primary health outcomes of four states of the United States. The context of this study is the potential association among health care disparities and myriad DOH, among them, the restrictive nurse practitioner (NP) scope of practice (SOP) regulatory environment, which are documented to influence access to care and health outcomes.

METHODS

This descriptive study explores current NP SOP regulations, access to primary care, and health outcomes of key chronic disease indicators-diabetes, hypertension, and obesity in Alabama, Colorado, Mississippi, and Utah. These states represent both the greatest disparity in chronic disease health outcomes (obesity, diabetes, and hypertension) and the greatest difference in modernization of their NP SOP laws. The Affordable Care Act has greatly expanded access to health care. However, it is estimated that 23 million Americans, 7% of its total population, will remain uninsured by 2019.

DISCUSSION

Restrictive and inconsistent NP SOP policies may continue to contribute to health workforce capacity and population health disparities across the country, with particular concern for primary care indicators. The study findings bring into question whether states with more restrictive NP SOP regulations impact access to primary care, which may in turn influence population health outcomes. These findings suggest the need for further research. NPs are essential for meeting the increasing demands of primary care in the United States, and quality-of-care indicator research supports their use.
