Assessing the Impact of Patient-Centered Medical Home Principles on Hypertension Outcomes Among Patients of HRSA-Funded Health Centers

To What Extent Are ACO and PCMH Models Advancing the Triple Aim Objective? Implications and Considerations for Primary Care Medical Practices

Accountable care organizations (ACOs) and patient-centered medical homes (PCMHs) have emerged to advance the health care system by achieving the Triple Aim of improving population health, reducing costs, and enhancing the patient experience. This review examines evidence regarding the relationship between these innovative care models and care outcomes, costs, and patient experiences. The 28 articles summarized in this review show that ACO and PCMH models play an important role in achieving the Triple Aim, when compared with conventional care models. However, there can be drawbacks associated with model implementation. The long-term success of these models still merits further investigation.

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.

Proceedings From a National Heart, Lung, and Blood Institute and the Centers for Disease Control and Prevention Workshop to Control Hypertension

Hypertension treatment and control prevent more cardiovascular events than management of other modifiable risk factors. Although the age-adjusted proportion of US adults with controlled blood pressure (BP) defined as <140/90 mm Hg, improved from 31.8% in 1999-2000 to 48.5% in 2007-2008, it remained stable through 2013-2014 and declined to 43.7% in 2017-2018. To address the rapid decline in hypertension control, the National Heart, Lung, and Blood Institute and the Division for Heart Disease and Stroke Prevention of the Centers for Disease Control and Prevention convened a virtual workshop with multidisciplinary national experts. Also, the group sought to identify opportunities to reverse the adverse trend and further improve hypertension control. The workshop immediately preceded the Surgeon General's Call to Action to Control Hypertension, which recognized a stagnation in progress with hypertension control. The presentations and discussions included potential reasons for the decline and challenges in hypertension control, possible "big ideas," and multisector approaches that could reverse the current trend while addressing knowledge gaps and research priorities. The broad set of "big ideas" was comprised of various activities that may improve hypertension control, including: interventions to engage patients, promotion of self-measured BP monitoring with clinical support, supporting team-based care, implementing telehealth, enhancing community-clinical linkages, advancing precision population health, developing tailored public health messaging, simplifying hypertension treatment, using process and outcomes quality metrics to foster accountability and efficiency, improving access to high-quality health care, addressing social determinants of health, supporting cardiovascular public health and research, and lowering financial barriers to hypertension control.

Health care utilization among beneficiaries with diabetes from federally qualified health centers: Analysis from a Medicaid managed care organization

We examined health care utilization among federally qualified health center (FQHCs) users from a Medicaid managed care organization based on 2016 administrative claims data (n = 8,402). FQHC users had fewer primary care visits (Adjusted Incidence Rate Ratios (aIRR): 0.82; 95% CI: 0.76-0.88) compared with non-FQHC users. Statistically significant differences were not observed in emergency department visits (aIRR: 1.19; 95% CI: 0.98-1.46) and hospitalizations (aIRR: 1.03; 95% CI: 0.80-1.34). FQHCs provide comprehensive primary care to Medicaid managed care beneficiaries with diabetes in fewer PCP visits. Results provide evidence to health policy experts and MCOs to increase provider network contracting with FQHCs.
