Patient Outcomes Associated With Utilization of Education, Case Management, and Advanced Practice Pharmacy Services by American Indian and Alaska Native Peoples With Diabetes

Pharmacists Colocated With Primary Care Physicians: Understanding Delivery of Interprofessional Primary Care

BACKGROUND

While evidence supports interprofessional primary care models that include pharmacists, the extent to which pharmacists are working in primary care and the factors associated with colocation is unknown.

OBJECTIVES

This study aimed to analyze the physical colocation of pharmacists with primary care providers (PCPs) and examine predictors associated with colocation.

RESEARCH DESIGN

This is a retrospective cross-sectional study of pharmacists and PCPs with individual National Provider Identifiers in the National Plan and Provider Enumeration System's database. Pharmacist and PCP practice addresses of the health care professionals were geocoded, and distances less than 0.1 miles were considered physically colocated.

SUBJECTS

In all, 502,373 physicians and 221,534 pharmacists were included.

RESULTS

When excluding hospital-based pharmacists, 1 in 10 (11%) pharmacists were colocated with a PCP. Pharmacists in urban settings were more likely to be colocated than those in rural areas (OR=1.32, CI: 1.26-1.38). Counties with the highest proportion of licensed pharmacists per 100,000 people in the county had higher colocation (OR=1.38, CI: 1.32-1.45). Colocation was significantly higher in states with an expanded scope of practice (OR 1.37, CI: 1.32-1.42) and those that have expanded Medicaid (OR 1.07, CI: 1.03-1.11). Colocated pharmacists more commonly worked in larger physician practices.

CONCLUSION

Although including pharmacists on primary care teams improves clinical outcomes, reduces health care costs, and enhances patient and provider experience, colocation appears to be unevenly dispersed across the United States, with lower rates in rural areas. As the integration of pharmacists in primary care continues to expand, knowing the prevalence and facilitators of growth will be helpful to policymakers, researchers, and clinical administrators.

Racial and Ethnic Equity in Care for Hypertension and Diabetes in an Urban Indian Health Organization

Approximately 70% of American Indian/Alaska Native (AI/AN) individuals reside in urban areas. Urban Indian Health Organizations (UIHOs) provide culturally engaged primary care for AI/AN patients and members of other racial and ethnic groups who have experienced disparities in diabetes and hypertension care, and are commonly affected by social and economic barriers to care. We assessed whether disparities were present between the racial and ethnic groups served by the largest UIHO in the USA. We developed retrospective cohorts of patients with hypertension or diabetes receiving primary care from this UIHO, measuring differences between AI/AN, Spanish-preferring Latinx, English-preferring Latinx, Black, and White patients in mean systolic blood pressure (SBP) and mean hemoglobin A1c (A1c) as primary outcomes. To assess processes of care, we also compared visit intensity, missed visits, and medication treatment intensity in regression models adjusted for sociodemographic and clinical characteristics. For hypertension (n = 2148), adjusted mean SBP ranged from 135.8 mm Hg among Whites to 141.3 mm Hg among Blacks (p = 0.06). For diabetes (n = 1211), adjusted A1c ranged from 7.7% among English-preferring Latinx to 8.7% among Blacks (p = 0.38). Care processes for both hypertension and diabetes varied across groups. No group consistently received lower-quality care. This UIHO provided care of comparable quality for hypertension and diabetes among urban-dwelling AI/ANs and members of other racial, ethnic, and language preference groups. Systematic assessments of care quality in UIHOs may help demonstrate the importance of their role in providing care and improve the quality of care.

Tribal Perspectives on Hypertension: Results From the Center for Native American Health Native-CHART Needs Assessment

PURPOSE AND OBJECTIVES

American Indian/Alaska Native (AI/AN) hypertension contributes to cardiovascular disease, the leading cause of premature death in this population. The purpose of this article is to document strategies, concerns, and barriers related to hypertension and cardiovascular disease from Native-Controlling Hypertension and Risks through Technology (Native-CHART) symposiums facilitated by the Center for Native American Health (CNAH). The objectives of this evaluation were to combine Health Needs Assessment (HNA) data and explore barriers and strategies related to hypertension while assessing changes in participants' perspectives over time (2017-2021).

APPROACH

CNAH followed an iterative process each year for planning the HNA, facilitating the HNA, and refining and reflecting on HNA findings over time. This involved 3 interconnected steps: (1) developing a shared understanding for the HNA, "Why are we here?," (2) facilitating the HNA during annual symposiums "What do we do?," and (3) reflecting on "What did we learn?".

EVALUATION METHODS

Data were collected using a culturally centered HNA co-created by the CNAH team and tribal partners. Qualitative data analysis utilized a culturally centered thematic approach and NVivo software version 12.0. Quantitative data analysis included summarizing frequency counts and descriptive statistics using Microsoft Excel.

RESULTS

Over the 5-year period, 212 Native-CHART symposium participants completed HNAs. Data collected from HNAs show persistent barriers and concerns and illuminate potential strategies to address AI/AN hypertension. Future efforts must explore effective strategies that build on community strengths, culture and traditions, and existing resources. This is the path forward.

IMPLICATIONS FOR PUBLIC HEALTH

CNAH's culturally centered and unique HNA approach helped assess participant perspectives over time. CNAH facilitated symposiums over multiple years, even amid a global pandemic. This demonstrates resilience and continuity of community outreach when it is needed the most. Other universities and tribal partners could benefit from this iterative approach as they work to design HNAs with tribal populations.

Use of clinical pharmacy services by American Indians and Alaska Native adults with cardiovascular disease

Introduction

The Indian Health Service (IHS) and Tribal health programs provide clinical pharmacy services to improve health outcomes among American Indian and Alaska Native (AI/AN) adults with cardiovascular disease (CVD).

Objectives

The study's primary objective was to describe characteristics, including social determinants of health (SDOH), associated with clinical pharmacy utilization by AI/ANs with CVD who accessed IHS/Tribal services. A secondary objective assessed changes in systolic blood pressure (SBP) associated with such utilization.

Methods

Analysis included IHS data for 9844 adults aged 18 and older with CVD who lived in 5 locations. Multivariable logistic regression was used to examine patient characteristics (eg, age, sex, health status, SDOH) associated with clinical pharmacy utilization in fiscal year (FY) 2012. A propensity score model was employed to estimate the association of elevated SBP in FY2013 with FY2012 clinical pharmacy utilization.

Results

Nearly 15% of adults with CVD used clinical pharmacy services. Among adults with CVD, the odds of clinical pharmacy use were higher among adults diagnosed with congestive heart failure (adjusted odds ratio [OR] = 1.22; 95% CI:1.01-1.47), other types of heart disease not including ischemia (OR = 1.40; 95% CI: 1.18-1.65), and vascular disease (OR = 1.23; 95% CI: 1.04-1.46), compared to adults without these conditions. Diabetes (OR = 4.05, 95% CI: 3.29-5.00) and anticoagulation medication use (OR = 20.88, 95% CI: 16.76-20.61) were associated with substantially higher odds of clinical pharmacy utilization. Medicaid coverage (OR = 0.72; 95% CI: 0.56-0.93) and longer travel times to services (OR = 0.87; 95% CI: 0.83-0.92) were each associated with lower odds. FY2012 clinical pharmacy users had lower odds of elevated SBP (OR = 0.71 95% CI: 0.58-0.87) in FY2013 than nonusers.

Conclusion

In addition to health status, SDOH (eg, Medicaid coverage, longer travel times) influenced clinical pharmacy utilization. Understanding characteristics associated with clinical pharmacy utilization may assist IHS/Tribal health programs in efforts to support optimization of these services.

Diabetes Prevention and Care Capacity at Urban Indian Health Organizations

American Indian and Alaska Native (AI/AN) people suffer a disproportionate burden of diabetes and cardiovascular disease. Urban Indian Health Organizations (UIHOs) are an important source of diabetes services for urban AI/AN people. Two evidence-based interventions-diabetes prevention (DP) and healthy heart (HH)-have been implemented and evaluated primarily in rural, reservation settings. This work examines the capacity, challenges and strengths of UIHOs in implementing diabetes programs. Methods: We applied an original survey, supplemented with publicly-available data, to assess eight organizational capacity domains, strengths and challenges of UIHOs with respect to diabetes prevention and care. We summarized and compared (Fisher's and Kruskal-Wallis exact tests) items in each organizational capacity domain for DP and HH implementers vs. non-implementers and conducted a thematic analysis of strengths and challenges. Results: Of the 33 UIHOs providing services in 2017, individuals from 30 sites (91% of UIHOs) replied to the survey. Eight UIHOs (27%) had participated in either DP (n = 6) or HH (n = 2). Implementers reported having more staff than non-implementers (117.0 vs. 53.5; p = 0.02). Implementers had larger budgets, ~$10 million of total revenue compared to $2.5 million for non-implementers (p = 0.01). UIHO strengths included: physical infrastructure, dedicated leadership and staff, and community relationships. Areas to strengthen included: staff training and retention, ensuring sufficient and consistent funding, and data infrastructure. Conclusions: Strengthening UIHOs across organizational capacity domains will be important for implementing evidence-based diabetes interventions, increasing their uptake, and sustaining these interventions for AI/AN people living in urban areas of the U.S.
