Innovative Population Health Model Associated With Reduced Emergency Department Use And Inpatient Hospitalizations

Kidney and Cardiovascular Protection Using Dietary Acid Reduction in Primary Hypertension: A Five-Year, Interventional, Randomized, Control Trial

BACKGROUND

High fruit and vegetable diets are associated with reduced chronic kidney disease and cardiovascular disease but are infrequently used in hypertension treatment. Low acid diets are also associated with reduced chronic kidney disease and cardiovascular disease, and fruits and vegetables or oral sodium bicarbonate (NaHCO3) lowers dietary acid.

METHODS

We randomized 153 hypertensive macroalbuminuric patients receiving pharmacologic chronic kidney disease and cardiovascular disease protection to get fruits and vegetables, oral NaHCO3, or Usual Care. We assessed the course of kidney disease progression and cardiovascular disease risk indices over five years.

RESULTS

Chronic kidney disease progression was slower in participants receiving fruits and vegetables or oral NaHCO3 than Usual Care [mean (SE)] [-1.08 (0.06) and -1.17 (0.07) vs. -1.94 (0.11) mL/min/1.73m2/ year, respectively, P's< .001). Yet, systolic blood pressure was lower, and cardiovascular disease risk indices improved more in participants receiving fruits and vegetables than in those receiving NaHCO3 or Usual Care. These cardiovascular benefits of fruits and vegetables were achieved despite lower doses of pharmacologic chronic kidney disease and cardiovascular disease protection.

CONCLUSION

The trial supports fruits and vegetables as foundational hypertension treatment to reduce chronic kidney disease progression and cardiovascular disease risk.

Precision emergency medicine

BACKGROUND

Precision health is a burgeoning scientific discipline that aims to incorporate individual variability in biological, behavioral, and social factors to develop personalized health solutions. To date, emergency medicine has not deeply engaged in the precision health movement. However, rapid advances in health technology, data science, and medical informatics offer new opportunities for emergency medicine to realize the promises of precision health.

METHODS

In this article, we conceptualize precision emergency medicine as an emerging paradigm and identify key drivers of its implementation into current and future clinical practice. We acknowledge important obstacles to the specialty-wide adoption of precision emergency medicine and offer solutions that conceive a successful path forward.

RESULTS

Precision emergency medicine is defined as the use of information and technology to deliver acute care effectively, efficiently, and authentically to individual patients and their communities. Key drivers and opportunities include leveraging human data, capitalizing on technology and digital tools, providing deliberate access to care, advancing population health, and reimagining provider education and roles. Overcoming challenges in equity, privacy, and cost is essential for success. We close with a call to action to proactively incorporate precision health into the clinical practice of emergency medicine, the training of future emergency physicians, and the research agenda of the specialty.

CONCLUSIONS

Precision emergency medicine leverages new technology and data-driven artificial intelligence to advance diagnostic testing, individualize patient care plans and therapeutics, and strategically refine the convergence of the health system and the community.

The Fruit and Veggies for Kidney Health Study: A Prospective Randomized Trial

Rationale & Objective

Providing fruits and vegetables (F&Vs) to health care system patients with elevated urine albumin-creatinine ratio (ACR) reduced ACR, slowed chronic kidney disease (CKD) progression and reduced cardiovascular disease (CVD) risk factors in previous studies. This study evaluated a community-based strategy in lower-income populations to identify African Americans with elevated ACR before health care system involvement and sustain them in a 6-month F&V protocol with (F&V + Cook) and without (F&V Only) cooking instructions, with the hypothesis that adjuvant cooking instructions with F&Vs would further reduce ACR.

Study Design

Prospective, randomized, parallel 2-arm design.

Setting & Participants

African American adults with ACR >10 mg/g creatinine randomized to 1 of 2 study arms.

Interventions

Two cups/day of F&Vs with or without cooking instructions in participants followed 6 months.

Outcomes

Participants sustaining the F&V protocol and between-group indicators of CVD risk, kidney injury, and dietary intake at 6 weeks and 6 months.

Results

A total of 142 African American adults (mean age, 57.0 years; ACR, 27.4 mg/g; body mass index, 34.4; 24.9% CKD 1; 24.8% CKD 2; 50.4% CKD 3; 55% female) randomized to F&V Only (n=72) or F&V + Cook (n=70), and 71% were retained at 6 months. Participants received 90% of available F&V pick-ups over 6 weeks and 69% over 6 months. In the adjusted model, 6-month ACR was 31% lower for F&V + Cook than F&V Only (P = 0.02). Net 6-week F&V intake significantly increased and biometric variables improved for participants combined into a single group.

Limitations

Small sample size, low-baseline ACR, and potential nonresponse bias for 24-hour dietary recall measure.

Conclusions

These data support the feasibility of identifying community-dwelling African Americans with ACR indicating elevated CVD and CKD risk and sustaining a F&V protocol shown to improve kidney outcomes and CVD risk factors and provides preliminary evidence that cooking instructions adjuvant to F&Vs are needed to lower ACR.

Funding

National Institute on Diabetes, Digestive, and Kidney Diseases grant "Reducing chronic kidney disease burden in an underserved population" (R21DK113440).

Trial Registration

NCT03832166.

Plain-Language Summary

African Americans, particularly those in low-income communities, have increased rates of chronic kidney disease (CKD) with worsening outcomes over time. Giving fruits and vegetables to individuals with CKD identified in health care systems was previously shown to reduce kidney damage, measured by urine protein albumin, and slow kidney function decline. We recruited African Americans in low-income communities with increased urine albumin levels. They received fruits and vegetables for 6 months, and we tested whether added cooking instructions further reduced urine albumin levels. Most participants continued to receive fruits and vegetables throughout the 6 months. Those given cooking instructions had lower urine albumin levels after 6 months, indicating decreased kidney damage. Providing cooking instructions with fruits and vegetables appears to lessen kidney damage more than just fruits and vegetables alone.

Proactive Detection (PROTECT) and Safety Planning to Shorten Emergency Department Stays for Psychiatric Patients

OBJECTIVE

A literature gap exists for interventions to decrease average length of stay (ALOS) for patients with psychiatric presentations at the emergency department (ED). Long ALOSs are often related to sequential assessments of patients with high suicide risk or patients awaiting an inpatient bed. Safety planning may provide opportunities for diverting patients to the community and for reducing ED ALOS. This study reports on the impact of a safety-planning approach based on the PROTECT (proactive detection) framework for suicide prevention.

METHODS

A complex intervention (comprising leadership, governance, and innovation) was instrumental in embedding a new clinical culture of proactive detection and positive risk management through safety planning at Princess Alexandra Hospital in Brisbane, Queensland, Australia. Practice as usual continued at a comparator nonintervention site (NIS). In total, 24,515 psychiatric presentations over 24 months were grouped into monthly averages for key outcomes, providing a sample size of 24 at each site. A difference-in-differences analysis across sites, preintervention (January-November 2019) and postimplementation (December 2019-December 2020), was used to estimate the intervention's impact.

RESULTS

ED ALOS for psychiatric presentations, patients with an ALOS >12 hours, patients with an ALOS >24 hours, and inpatient psychiatric admissions decreased significantly compared with NIS (p<0.01) pre- and postimplementation of the safety-planning intervention.

CONCLUSIONS

Embedding a recovery-oriented culture of safety significantly reduced ED ALOS for psychiatric evaluations. Leadership, governance, and innovative practices that shift the focus of assessment and care from a mindset of risk prediction to one of prevention through collaborative safety planning as outlined in the PROTECT framework may have far-reaching benefits for patient care.

Parental Childhood Adversity and Pediatric Emergency Department Utilization: A Pilot Study

OBJECTIVES

Adverse childhood experiences (ACEs) including physical, emotional, or sexual abuse; neglect; and/or exposure to household instability have been associated with adult emergency department utilization, but the impact of parental ACEs on pediatric emergency department (PED) utilization has not been studied. The primary aim was to determine if parental ACEs impact resource utilization as measured by (1) frequency of PED utilization, (2) acuity of PED visits, and (3) 72-hour PED return rates. The secondary aim was to determine if resilience interacts with the impact of parental ACEs on PED utilization.

METHODS

This study is a cross-sectional survey using previously validated measures of ACEs, resiliency, and social determinants of health screening. Surveys were administered from October 17, 2019, to November 27, 2019, via iPad by research assistants in our institution's PEDs. Survey responses were linked to data abstracted from the electronic health record. Descriptive statistics were used to characterize our study population. Pearson correlation was used to identify correlation between ACEs, social determinants of health, and PED utilization measures.

RESULTS

A total of 251 parents had complete data. Parental ACEs were positively associated with frequency of PED visits (incidence rate ratio, 1.013). In addition, high levels of parental resilience attenuated the association between parental ACEs and the number of severe acuity visits and were associated with fewer 72-hour return visits (incidence rate ratio, 0.49).

CONCLUSIONS

Parental ACEs appear to be positively associated with frequency of PED utilization and inversely associated with higher-acuity PED visits and parental resiliency.

Primary Medical Care Integrated with Healthy Eating and Healthy Moving is Essential to Reduce Chronic Kidney Disease Progression

Increasing adverse outcomes in patients with chronic kidney disease reflect growth of patients with early-stage chronic kidney disease and their increasing per population rates of these outcomes. Progression of chronic kidney disease, more than current level of kidney function, is the primary driver of adverse chronic kidney disease-related outcomes. Racial/ethnic minorities progress faster to end-stage kidney disease with greater risk for adverse outcomes. Diabetes and hypertension cause two-thirds of end-stage kidney disease, for which primary medical care integrated with healthy eating and increased physical activity (healthy moving) slows chronic kidney disease progression. Patients with early-stage chronic kidney disease are appropriately managed by primary care practices but most lack infrastructure to facilitate this integration that reduces adverse chronic kidney disease-related outcomes. Individuals of low socioeconomic status are at greater chronic kidney disease risk, and flexible regulatory options in Medicaid can fund infrastructure to facilitate healthy eating and healthy moving integration with primary medical care. This integration promises to reduce chronic kidney disease-related adverse outcomes, disproportionately in racial/ethnic minorities, and thereby reduce chronic kidney disease-related health disparities.

Integrating Population Health Strategies into Primary Care: Impact on Outcomes and Hospital Use for Low-Income Adults

Objective

Our objectives were two-fold: 1) To evaluate the benefits of population health strategies focused on social determinants of health and integrated into the primary care medical home (PCMH) and 2) to determine how these strategies impact diabetes and cardiovascular disease outcomes among a low-income, primarily minority community. We also investigated associations between these outcomes and emergency department (ED) and inpatient (IP) use and costs.

Design

Retrospective cohort.

Setting

Community-based PCMH: Baylor Scott & White Health and Wellness Center (BSW HWC).

Patients/Participants

All patients who attended at least two primary care visits at BSW HWC within a 12-month time span from 2011-2015.

Methods

Outcomes for patients participating in PCMH only (PCMH) as compared to PCMH plus population health services (PCMH+PoPH) were compared using electronic health record data.

Main Outcomes

Diastolic and systolic blood pressure, hemoglobin A1c, ED visits and costs, and IP hospitalizations and costs were examined.

Results

From 2011-2015, 445 patients (age=46±12 years, 63% African American, 61% female, 69.5% uninsured) were included. Adjusted regression analyses indicated PCMH+PoPH had greater improvement in diabetes outcomes (prediabetes HbA1c= -.65[SE=.32], P=.04; diabetes HbA1c= -.74 [SE=.37], P<.05) and 37% lower ED costs than the PCMH group (P=.01). Worsening chronic disease risk factors was associated with 39% higher expected ED visits (P<.01), whereas improved chronic disease risk was associated with 32% fewer ED visits (P=.04).

Conclusions

Integrating population health services into the PCMH can improve chronic disease outcomes, and impact hospital utilization and cost in un- or under-insured populations.

Expanding the Curriculum in a School of Public Health

Public health education has long been concentrated in a core set of public health disciplines such as epidemiology, biostatistics, and environmental health. Despite leaps forward in our understanding of the myriad influences on public health, little has changed in the organization of our educational systems. One issue brought to the forefront of public consciousness by the COVID-19 pandemic is the importance of leisure experiences, such as nature walks, to mental and physical well-being. In this descriptive best practice article, we discuss our approach to expanding the notion of a school of public health and provide examples of how disciplines and subjects outside of the “norms” of public health education, including leisure studies, can help better prepare students for their future in the field. Leisure studies is just one of many subject areas that can add value to public health pedagogy, and we envision many other subject areas and departments integrating into schools of public health in the future.

Embedded Health Systems Science as a driver of care improvement within an integrated delivery organization

BACKGROUND

Embedded Health Systems Science (HSS) has the potential to reduce gaps between research and delivery of evidence-based medicine. Models are needed to guide the development of embedded HSS in health care delivery organizations particularly with the rise of value-based care.

METHODS

The development of HSS infrastructure at a large nonprofit health care delivery organization is described, along with an embedded HSS diabetes study to illustrate the integration of program specific data, electronic health records, and health care system data infrastructure. To compare diabetes outcomes across four evidenced-based programs, a control group was developed from EHR data using propensity score matching. Mixed effect adjusted models were used to estimate reductions in hemoglobin A1c (HbA1c) and body weight.

RESULTS

Adjusted analyses using an EHR derived comparison group demonstrated significantly different findings than unadjusted pre to post analyses. The embedded HSS study indicates that appropriate statistical methods, staff with required expertise, and integration with health system data infrastructure are needed to develop timely and rigorous HSS outcomes that effectively improve patient care.

CONCLUSIONS

Embedded HSS has the potential to inform value-based care models and contribute to evidence-based medicine approaches that improve patient care. Although developing system wide integrated data structures and staff with the appropriate skills requires substantial effort, the outcome is more reliable evaluations that lead to higher quality and higher value care.

IMPLICATIONS

Health care delivery organizations can improve patient care by dedicating resources to embed HSS into its routine operations.

Evaluation of an Electronic Health Record Referral Process to Enhance Participation in Evidence-Based Arthritis Interventions

PURPOSE AND OBJECTIVES

Effective community-based programs to manage arthritis exist, but many adults with arthritis are unaware that these programs are available in their communities. An electronic health record (EHR) referral intervention was designed to strengthen health care and community-based partnerships and increase participation in these arthritis programs. The intervention was developed in response to a national effort that aimed to enhance the health, wellness, and quality of life for people with arthritis by increasing the awareness and availability of, and participation in arthritis-appropriate evidence-based interventions.

INTERVENTION APPROACH

The National Recreation and Park Association recruited 4 park and recreation agencies and their health care partners to implement an EHR-based retrospective and point-of-care referral intervention. Eligible for referral were adults aged 45 or older with an arthritis condition who were seen by a physician within the past 18 months, and were living within the park and recreation service area. After health care organizations identified eligible adults, they either mailed communication packages describing the availability and benefits of the intervention and conducted phone calls to encourage arthritis-appropriate intervention participation or counseled and referred patients during an office visit.

EVALUATION METHODS

The pilot was assessed by using semi-structured interviews with key intervention staff members and the Consolidated Framework for Implementation Research.

RESULTS

Our approach resulted in referrals for 3,660 people, 1,063 (29%) of whom participated in an intervention. Analysis of key informant interviews also highlighted the specific contextual factors, facilitators, and barriers that influenced the adaptation and overall implementation of the referral intervention.

IMPLICATIONS FOR PUBLIC HEALTH

Our pilot demonstrates that successful coordination between health care organizations and community-based organizations can promote awareness of and participation in community-based programs. An understanding of the contextual factors and lessons learned can be used to inform processes that can lead to more effective and sustainable health care and community-based partnerships.

Patient and Family Engaged Care: An Essential Element of Health Equity

In this paper, we emphasize and explore health equity as an integral component of a culture of patient and family engaged care (PFEC), rather than an isolated or peripheral outcome. To examine the role of PFEC in addressing health inequities, we build on the 2017 NAM Perspectives discussion paper "Harnessing Evidence and Experience to Change Culture: A Guiding Framework for Patient and Family Engaged Care." Informed by both scientific evidence and the lived experience of patients, their care partners, practitioners, and health system leaders, the paper by Frampton et al. introduced a novel Guiding Framework that delineates critical elements that work together to co-create a culture of PFEC, while also depicting a logical sequencing for implementation that facilitates progressive change and improvement toward the Quadruple Aim outcomes of better culture, better care, better health, and lower costs. In this paper, the authors highlight the need to integrate addressing health and health care disparities and improving health equity as core components of the framework to ensure the culture and policy changes necessary to meaningfully engage patients, health system staff, families, and communities.

Evaluation of a National Care Coordination Program to Reduce Utilization Among High-cost, High-need Medicaid Beneficiaries With Diabetes

BACKGROUND

Medical, behavioral, and social determinants of health are each associated with high levels of emergency department (ED) visits and hospitalizations.

OBJECTIVE

The objective of this study was to evaluate a care coordination program designed to provide combined "whole-person care," integrating medical, behavioral, and social support for high-cost, high-need Medicaid beneficiaries by targeting access barriers and social determinants.

RESEARCH DESIGN

Individual-level interrupted time series with a comparator group, using person-month as the unit of analysis.

SUBJECTS

A total of 42,214 UnitedHealthcare Medicaid beneficiaries (194,834 person-months) age 21 years or above with diabetes, with Temporary Assistance to Needy Families, Medicaid expansion, Supplemental Security Income without Medicare, or dual Medicaid/Medicare.

MEASURES

Our outcome measures were any hospitalizations and any ED visits in a given month. Covariates of interest included an indicator for intervention versus comparator group and indicator and spline variables measuring changes in an outcome's time trend after program enrollment.

RESULTS

Overall, 6 of the 8 examined comparisons were not statistically significant. Among Supplemental Security Income beneficiaries, we observed a larger projected decrease in ED visit risk among the intervention sample versus the comparator sample at 12 months postenrollment (difference-in-difference: -6.6%; 95% confidence interval: -11.2%, -2.1%). Among expansion beneficiaries, we observed a greater decrease in hospitalization risk among the intervention sample versus the comparator sample at 12 months postenrollment (difference-in-difference: -5.8%; 95% confidence interval: -11.4%, -0.2%).

CONCLUSION

A care coordination program designed to reduce utilization among high-cost, high-need Medicaid beneficiaries was associated with fewer ED visits and hospitalizations for patients with diabetes in selected Medicaid programs but not others.

Comparing neighborhood-based indices of socioeconomic risk factors and potentially preventable emergency department utilization

BACKGROUND

Neighborhood stress score (NSS) and area deprivation index (ADI) are two neighborhood-based composite measures used to quantify an individual's socioeconomic risk based on home location. In this analysis, we compare the relationships between an individual's socioeconomic risk, based on each of these measures, and potentially preventable acute care utilization.

METHODS

Using emergency department (ED) visit data from two academic medical centers in Boston, Massachusetts, we conducted adjusted Poisson regressions of ADI decile and NSS decile with counts of low acuity ED visits, admissions for ambulatory care sensitive conditions (ACSCs), and patients with high frequency ED utilization at the census block group (CBG) level within the greater Boston area.

RESULTS

Both NSS and ADI decile were associated with elevated rates of utilization, although the associated incidence rate ratios (IRRs) for NSS were higher than those for ADI across all three measures. NSS decile was associated with IRRs of 1.11 [95% CI: 1.10-1.12], 1.16 [1.14-1.17], and 1.22 [1.19-1.25] for ACSC admissions, low acuity ED visits, and patients with high frequency ED utilization, respectively; compared with 1.04 [1.04-1.05], 1.11 [1.10-1.11], and 1.10 [1.08-1.12] for ADI decile.

CONCLUSION

ADI and NSS both represent effective tools to assess the potential impact of geographically-linked socioeconomic drivers of health on potentially preventable acute care utilization. NSS decile was associated with a greater effect size for each measure of utilization suggesting that this may be a stronger predictor, however, additional research is necessary to evaluate these findings in other contexts.

Characteristics of Non-Emergent Visits in Emergency Departments: Profiles and Longitudinal Pattern Changes in Taiwan, 2000-2010

An increasing number of emergency department (ED) visits have posed a challenge to health systems in many countries, but an understanding of non-emergent ED visits has remained limited and contentious. This retrospective study analyzed ED visits using three representative cohorts from routine data to explore the profiles and longitudinal pattern changes of non-emergent ED visits in Taiwan. Systematic-, personal-, and ED visit-level data were analyzed using a logistic regression model. Average marginal effects were calculated to compare the effects of each factor. The annual ED visit rate increased up to 261.3 per 1000 population in 2010, and a significant one-third of visits were considered as non-emergent. The rapidly growing utilization of ED visits underwent a watershed change after cost-sharing payments between patients and medical institutions were increased in 2005. In addition to cohort effects resulting from cost-sharing payment changes, all factors were significantly associated with non-emergent ED visits with different levels of impact. We concluded that non-emergent ED visits were associated with multifaceted factors, but the change to cost-sharing payment, being female, younger age, and geographical residence were the most predictive factors. This information would enhance the implementation of evidence-based strategies to optimize ED use.
