Will Community Health Centers Survive COVID-19

Topic: COVID-19
Resource Type: Publication
Year: 2020
Author(s): Brad Wright, Erin Fraher, Marni Gywther Holder, Jill Akiyama
Community Health Centers (CHCs) are critical to our nation's ability to respond to COVID‐19 in rural and underserved communities. Rural residents are at increased risk of poor outcomes due to age and health status, and there are substantially fewer healthcare resources available in rural areas, meaning that once the virus becomes more widespread in these communities, the results could be disastrous. This commentary examines the real threat COVID-19 poses to CHCs and the current efforts being made to save them.

What EHRs Tell Us About How We Deploy Health Professionals to Address the Social Determinants of Health

Topic: Health Equity
Resource Type: Brief
Year: 2020
Author(s): Erica Richman, Brianna Lombardi, Lisa de Saxe Zerden
Increasing aware­ness of the Social Determinants of Health (SDOH) has prompted health systems to im­plement strat­egies to screen for and address pa­tient SDOH. With the increased awareness comes the question of what workforce is needed to implement SDOH screening and re­lated inter­ventions? To answer, this research must be conducted for which healthcare workers screen for SDOH, who actually addresses needs related to patient SDOH, and how to incorporate screening and intervention into the clinic work­flows. This research brief uses Electronic Health Records (EHR) data to describe the mix of profession­als identifying and addressing pa­tient SDOH.

Prevention, health promotion, and social work: Aligning health and human service systems through a workforce for health.

Topic: Behavioral Health, Health Equity, Public Health
Resource Type: Publication
Year: 2020
Author(s): Ross AM, de Saxe Zerden L.
We call for increased attention to and investment in prevention and health promotion in the proposed 5As framework. We contend that effectively addressing SDOH and improving alignment between health and social systems require reconceptualization of the traditional health care workforce and renewed state and national advocacy efforts. A paradigm shift encompassing a broader "workforce for health" that is well trained in prevention, health promotion, and advocacy is critical to addressing SDOH, improving population health outcomes, and achieving health equity. Given their professional mission, training, expertise, and scope of practice, social workers are well positioned to lead this effort.

Skilled Nursing Facility Characteristics Associated With Financially Motivated Therapy and Relation to Quality

Topic: Allied Health, Long-Term Care, Nursing
Resource Type: Publication
Year: 2020
Author(s): Rachel Prusynski, Bianca Frogner, Arati Dahal, Susan Skillman, Tracy Mroz
In October 2019, the Centers for Medicare & Medicaid Services (CMS) implemented a new payment model for skilled nursing facilities (SNFs) that eliminated financial incentives to provide high-intensity therapy. Yet high-intensity therapy in SNFs has been linked to better quality outcomes, potentially putting patients at risk if clinically indicated therapy is reduced under the new payment model. A metric to help differentiate between financially motivated vs clinically indicated therapy in SNFs is thresholding: the percentage of patients receiving therapy within 10 minutes of reimbursement thresholds. This study examined which SNF characteristics are associated with thresholding and how thresholding relates to quality outcomes.

Assessing the Value of Pediatric Graduate Medical Education in Meeting State and National Needs

Topic: Health Careers, Medicine
Resource Type: Brief
Year: 2019
Author(s): Thomas Ricketts, Erin Fraher, Ryan Kandrack
Policies that support graduate medical education (GME) have goals of increasing the proportion of program graduates who remain in generalist practice and, for pediatrics, in subspecialties supported through the Children’s Hospital Graduate Medical Education Program. Policy attention has also focused on promoting practice in primary care health professional shortage areas, and in rural and micropolitan counties. Although individual states have spent millions of dollars annually on residency training, it has become apparent that they have little knowledge of what their investment yields in terms of producing a physician workforce that includes sufficient generalists and subspecialists that practice in underserved locations. This policy brief explores outcome metrics that can be used to evaluate pediatric GME investments in producing the workforce that meets state and national health care needs.
