Nurse-managed health centers and patient-centered medical homes could mitigate expected primary care physician shortage

Association of county-level provider density with hepatobiliary cancer incidence and mortality

BACKGROUND

Access to healthcare providers is a key factor in reducing cancer incidence and mortality, underscoring the significance of provider density as a crucial metric of health quality. We sought to characterize the association of provider density on hepatobiliary cancer population-level incidence and mortality.

STUDY DESIGN

County-level hepatobiliary cancer incidence and mortality data from 2016 to 2020 and provider data from 2016 to 2018 were obtained from the CDC and Area Health Resource File. Multivariable logistic regression was utilized to evaluate the relationship between provider density and hepatobiliary cancer incidence and mortality.

RESULTS

Among 1359 counties, 851 (62.6%) and 508 (37.4%) counties were categorized as urban and rural, respectively. The median number of providers in any given county was 104 (IQR: 44-306), while provider density was 120.1 (IQR: 86.7-172.2) per 100,000 population; median household income was $51,928 (IQR: $45,050-$61,655). Low provider-density counties were more likely to have a greater proportion of residents over 65 years of age (52.7% vs. 49.6%) who were uninsured (17.4% vs. 13.2%) versus higher provider-density counties (p < 0.05). Moreover, all-stage incidence, late-stage incidence, and mortality rates were higher in counties with low provider density. On multivariable analysis, moderate, and high provider density were associated with lower odds of all-stage incidence, late-stage incidence, and mortality.

CONCLUSION

Higher county-level provider density was associated with lower hepatobiliary cancer-related incidence and mortality. Efforts to increase access to healthcare providers may improve healthcare equity as well as long-term cancer outcomes.

Barriers and facilitators to healthcare for people without documentation status: A systematic integrative literature review

AIMS

To identify the barriers and facilitators to healthcare for people without documentation status.

DESIGN

We conducted a systematic integrative literature review following the Whittemore and Knafl methodology.

METHODS

Literature search was conducted to identify studies addressing barriers or facilitators to healthcare for people without documentation status in the United States between 2012 and 2022. Studies were critiqued for quality, with results analysed thematically using the social-ecological model.

DATA SOURCES

Searches were conducted in PubMed, PAIS, Web of Science, CINAHL and Psych Info in October 2022.

RESULTS

The review incorporated 30 studies (19 qualitative and 11 quantitative). People without documentation status encountered numerous healthcare barriers such as intrapersonal (lack of financial resources and health insurance, fear), interpersonal (language and cultural discrepancies, discrimination), community (bureaucratic requirements, anti-immigrant rhetoric) and policy-related barriers. Conversely, linguistically and culturally competent care, empathetic and representative staff, health navigators, safety-net clinics and supportive federal policies emerged as key facilitators.

CONCLUSION

These findings illuminate the complex healthcare disparities experienced by people without documentation status and underscore facilitators enhancing care accessibility. Future research is needed to explore interventions to increase access to care for this population.

IMPACT

This paper provides a comprehensive examination of the complex barriers and facilitators to healthcare for people without documentation status in the United States. The findings support the value of universal healthcare access, a priority of the World Health Organization, and can inform healthcare policies and practices worldwide.

REPORTING METHOD

The review was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution was needed.

TRIAL AND PROTOCOL REGISTRATION

The study protocol was registered with the PROSPERO database (registration number: CRD42022366289).

Treatment Disparities Among the Black Population and Their Influence on the Equitable Management of Chronic Pain

Introduction: Growing evidence suggests disparities in the prevalence, management, progression, and outcomes of chronic, nonmalignant pain-related conditions, especially for African American patients. Objective: The purpose of this review is to explore studied causative factors that influence the management of chronic pain among African Americans, including factors that result in disparate care that may contribute to unfavorable outcomes. Methods: This narrative review is based on available literature published on this topic published within the last 10 years. Results: Assessment of chronic pain is multifaceted, often complicated by patient medical comorbidities and a complex set of biopsychosocial/spiritual/financial and legal determinants. These complexities are further exacerbated by a patient's race, by provider bias, and by structural barriers-all intersecting and culminating in disparate outcomes. Conclusions: A comprehensive analysis is needed to identify quality improvement interventions and to mitigate major barriers contributing to disparities in the management of chronic pain in the African American population.

Optimal Staffing Models To Care For Frail Older Adults In Primary Care And Geriatrics Practices In The US

Different staffing configurations in primary and geriatric care practices could have implications for how best to deliver services that are essential for a growing population of older adults. Using data from a 2018 survey of physicians (MDs) and nurse practitioners (NPs) working in primary and geriatric care, we assessed whether different configurations were associated with better or worse performance on a number of standard process measures indicative of comprehensive, high-quality primary care. Practices with a large concentration of MDs had the highest estimated labor costs. Practices high in NPs and physician assistants (PAs) were most common in states that grant full scope of practice to NPs. The high-NP/PA configuration was associated with a 17-percentage-point greater probability of facilitating patient visits and a 26-percentage-point greater probability of providing the full bundle of primary care services compared with the high-MD model. Team-based configurations had a 27.7-percentage-point greater probability of providing the full bundle of primary care services. The complex needs of older adults may be best served by team-based practices with a broad provider mix that can provide a range of services in the office and the community.

Health care costs associated with primary care physicians versus nurse practitioners and physician assistants

BACKGROUND

Significant primary care provider (PCP) shortage exists in the United States. Expanding the scope of practice for nurse practitioners (NPs) and physician assistants (PAs) can help alleviate this shortage. The Department of Veterans' Affairs (VA) has been a pioneer in expanding the role of NPs and PAs in primary caregiving.

PURPOSE

This study evaluated the health care costs associated with VA patients cared for by NPs and PAs versus primary care physicians (physicians).

METHODS

A retrospective data analysis using two separate cohorts of VA patients, one with diabetes and the other with cardiovascular disease (CVD), was performed. The associations between PCP type and health care costs were analyzed using ordinary least square regressions with logarithmically transformed costs.

RESULTS

The analyses estimated 12% to 13% (US dollars [USD] 2,626) and 4% to 5% (USD 924) higher costs for patients assigned to physicians as compared with those assigned to NPs and PAs, after adjusting for baseline patient sociodemographics and disease burden, in the diabetes and CVD cohort, respectively. Given the average patient population size of a VA medical center, these cost differences amount to a total difference of USD 14 million/year per center and USD 5 million/year per center for diabetic and CVD patients, respectively.

IMPLICATIONS FOR PRACTICE

This study highlights the potential cost savings associated with primary caregiving by NPs and PAs. In light of the PCP shortage, the study supports increased involvement of NPs and PAs in primary caregiving. Future studies examining the reasons for these cost differences by provider type are required to provide more scientific evidence for regulatory decision making in this area.

Cross-sectional analysis of US scope of practice laws and employed physician assistants

OBJECTIVE

This study examined if the variation in physician assistant (PA) state scope of practice (SOP) laws across states are associated with number of employed PAs, PA demographics and PA/population ratio per state. The hypothesis was that less restrictive SOP laws will increase the demand for PAs and the number of PAs in a state.

DESIGN

Retrospective cross-sectional analysis at three time points: 1998, 2008, 2017.

SETTING

Fifty states and the District of Columbia.

PARTICIPANTS

Employed PAs in 1998, 2008, 2017.

METHODS

SOP laws were categorised as permissive, average and restrictive. Three national datasets were combined to allow for descriptive analysis of employed PAs by year and SOP categories. We used linear predictive models to generate and compare PA/population ratio least square means by SOP categories for each year. Models were adjusted for percent female PA and PAs mean age.

RESULTS

There was a median PA/population ratio of 23 per 100 000 population in 1998 and 33 in 2017. A heterogeneous expansion of SOP laws was seen with 17 states defined as super expanders while 15 were never adopters. In 2017, comparing restrictive to permissive states showed that in adjusted models permissive SOP laws were associated with 11.7 (p .03) increase in ratio of employed PAs per 100 000 population, demonstrating that states with permissive SOP laws have an increased PA density.

CONCLUSIONS

There has been steady growth in the mean PA/population ratio since the turn of the century. At the same time, PA SOP laws in the USA have expanded, with just 10 states remaining in the restrictive category. Permissive SOP laws are associated with an increase in the ratio of employed PAs per state population. As states work to meet the projected physician need, SOP expansion may be an important policy consideration to increase the PA workforce.

Implementing Enhanced Primary Care Registered Nurse Reimbursement in Rural Health Clinics: A Policy Analysis

Rural Health Clinics (RHCs) were created in 1977 to address the high health care needs, limited provider access, and poor health outcomes of rural Americans. Although innovative at their inception, the provider-centric model of RHC cost-based reimbursement structures has not evolved, leaving limited opportunities for change; many have failed. Comprehensive, proactive change is needed. Registered nurses (RNs) working at the top of their practice scope are a neglected clinical resource that can improve access, quality, value, and satisfaction for rural patient communities. RHC reimbursement policy must evolve to sustain and support this significant RN role. RNs have demonstrated value in care continuity and disease management, but there is little research on the utilization of RNs using their enhanced skill set in RHCs. Using the Bardach and Patashnik's eight steps of policy analysis, the authors will describe the background and regulations of RHCs, identify current barriers to improving the health of America's rural residents, and then provide evidence to support a new policy option according to the Quadruple Aim framework. The result is a sustainable policy recommendation designed to best serve rural communities.

Assessment of the Patient Protection and Affordable Care Act's Increase in Fees for Primary Care and Access to Care for Dual-Eligible Beneficiaries

IMPORTANCE

The Patient Protection and Affordable Care Act (ACA) temporarily increased primary care practitioners' (PCP) Medicaid fees to that of Medicare for 2013 to 2014 (fee bump) to help accommodate potential increases in demand for care with ACA coverage expansion. This also increased fees for PCPs treating dual-eligible Medicare and Medicaid beneficiaries in many states and eliminated payment differentials for dual-eligible vs non-dual-eligible Medicare beneficiaries that could limit access to care.

OBJECTIVE

To examine the association between the ACA fee bump and primary care visits for dual-eligible Medicare and Medicaid beneficiaries.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study used a difference-in-difference design and Medicare claims data from 2012 to 2016 to compare changes in visit rates for full-subsidy dual-eligible Medicare and Medicaid beneficiaries vs non-dual-eligible Medicare beneficiaries with low income whose fees did not change. Changes were examined overall and separately in states with temporary, extended, or minimal fee increases for dual-eligible vs non-dual-eligible beneficiaries in 2013 to 2014 (mandatory bump) and 2015 to 2016 (postbump or bump extension) vs 2012 (prebump). The study used linear regression models with beneficiary fixed effects, adjusting for time-changing area and beneficiary characteristics. Statistical analysis was performed from February 2018 to November 2019.

EXPOSURE

ACA-mandated Medicaid fee bump.

MAIN OUTCOMES AND MEASURES

Primary care visits per 100 beneficiaries overall and visits billed by physicians vs nurse practitioners and physician assistants.

RESULTS

The study included 3 052 044 dual-eligible and non-dual-eligible beneficiaries in 2012; 1 516 534 (49.7%) were aged 65 years or younger, 1 797 556 (58.9%) were women, and 1 754 626 (57.5%) had non-Hispanic White race/ethnicity. Overall primary care visit rates for dual-eligible beneficiaries were unchanged or decreased slightly relative to non-dual-eligible beneficiaries during the fee bump (2013-2014) and the postbump or bump extension period (2015-2016) vs baseline. Compared with non-dual-eligible beneficiaries, visit rates with primary care physicians declined more uniformly for dual-eligible beneficiaries across state groups and time periods (difference-in-difference: -0.37 [95% CI, -0.43 to -0.32] visits per 100 beneficiaries in 2013-2014 vs 2012; P < .001; and difference-in-difference: -0.62 [95% CI, -0.68 to -0.56] visits per 100 beneficiaries in 2015-2016 vs 2012; P < .001), whereas visits with nurse practitioners and physician assistants increased over time (difference-in-difference: 0.11 [95% CI, 0.08 to 0.14] visits per 100 beneficiaries in 2013-2014 vs 2012; P < .001; and difference-in-difference: 0.46 [95% CI, 0.43 to 0.50] visits per 100 beneficiaries in 2015-2016 vs 2012; P < .001). These changes, however, were not associated with the timing of the payment changes.

CONCLUSIONS AND RELEVANCE

The ACA fee bump was not associated with increases in primary care visits for dual-eligible Medicare and Medicaid beneficiaries. Visits for dual-eligible beneficiaries with primary care physicians decreased after the ACA, a decrease that was partially offset by increases in visits with nonphysician clinicians.

Practice Patterns, Work Environments, and Job Outcomes of Rural and Urban Primary Care Nurse Practitioners

As nurse practitioners (NPs) are increasingly relied on to deliver primary care in rural communities, it is critical to understand the contexts in which they work and whether they are characterized by work environments and infrastructures that facilitate the provision of high-quality patient care. This study compares urban and rural NPs using data from a survey of 1,244 primary care NPs in Arizona, California, New Jersey, Pennsylvania, Texas, and Washington. While rural and urban NPs have a number of similarities in terms of demographic characteristics, practice patterns, and job outcomes, they also have noteworthy differences. Rural NPs report higher levels of independent practice, fewer structural capabilities that facilitate quality care, and poorer relationships with physicians. Health care organizations in rural communities may need to invest in work environments and infrastructures that facilitate high-quality care and autonomous practice for NPs.

Establishing the nurse practitioner workforce in rural New Zealand: barriers and facilitators

INTRODUCTION The health sector is facing considerable challenges to meet the health needs of rural communities. Nurse practitioners (NPs) deliver primary health care (PHC) services similar to general practitioner (GP) services, within a health equity and social justice paradigm. Despite GP workforce deficits, New Zealand has been slow to effectively utilise NPs. AIM From a larger study exploring the establishment of NP services, this paper reports on the barriers and facilitators to becoming a NP in rural PHC. METHODS Overall, 13 NPs and 4 NP candidates participated in individual or group interviews. Participants were employed in a variety of PHC settings from six district health boards across New Zealand. Using a scaffold map constructed to show the stages of the pathway from nurse to NP, data were analysed to identify experiences and events that facilitated or were barriers to progress. RESULTS Experiences varied considerably between participants. Commitment to the development of the NP role in their local areas, including support, advanced clinical opportunities, supervision, funding and NP job opportunities, were critical to progression and success. Existing GP shortages and the desire to improve health outcomes for communities drove nurses to become NPs. DISCUSSION Implementation of the NP workforce across New Zealand remains ad hoc and inconsistent. While there are pockets of great progress, overall, the health sector has failed to embrace the contribution that NPs can make to PHC service delivery. A national approach is required to develop the NP workforce as a mainstream PHC provider.

How State Scope-of-Practice Policies Impact NP Care

Three projects examine the effect of NP practice acts on access to health care.

Utilization and Costs by Primary Care Provider Type: Are There Differences Among Diabetic Patients of Physicians, Nurse Practitioners, and Physician Assistants?

OBJECTIVE

The objective of this study was to compare health care utilization and costs among diabetes patients with physician, nurse practitioner (NP), or physician assistant (PA) primary care providers (PCPs).

RESEARCH DESIGN AND METHODS

Cohort study using Veterans Affairs (VA) electronic health record data to examine the relationship between PCP type and utilization and costs over 1 year in 368,481 adult, diabetes patients. Relationship between PCP type and utilization and costs in 2013 was examined with extensive adjustment for patient and facility characteristics. Emergency department and outpatient analyses used negative binomial models; hospitalizations used logistic regression. Costs were analyzed using generalized linear models.

RESULTS

PCPs were physicians, NPs, and PAs for 74.9% (n=276,009), 18.2% (n=67,120), and 6.9% (n=25,352) of patients respectively. Patients of NPs and PAs have lower odds of inpatient admission [odds ratio for NP vs. physician 0.90, 95% confidence interval (CI)=0.87-0.93; PA vs. physician 0.92, 95% CI=0.87-0.97], and lower emergency department use (0.67 visits on average for physicians, 95% CI=0.65-0.68; 0.60 for NPs, 95% CI=0.58-0.63; 0.59 for PAs, 95% CI=0.56-0.63). This translates into NPs and PAs having ~$500-$700 less health care costs per patient per year (P<0.0001).

CONCLUSIONS

Expanded use of NPs and PAs in the PCP role for some patients may be associated with notable cost savings. In our cohort, substituting care patterns and creating similar clinical situations in which they practice, NPs and PAs may have reduced costs of care by up to 150-190 million dollars in 2013.

Impact of nonphysician providers on spatial accessibility to primary care in Iowa

OBJECTIVE

To assess the impact of nonphysician providers on measures of spatial access to primary care in Iowa, a state where physician assistants and advanced practice registered nurses are considered primary care providers.

DATA SOURCES

2017 Iowa Health Professions Inventory (Carver College of Medicine), and minor civil division (MCD) level population data for Iowa from the American Community Survey.

STUDY DESIGN

We used a constrained optimization model to probabilistically allocate patient populations to nearby (within a 30-minute drive) primary care providers. We compared the results (across 10 000 scenarios) using only primary care physicians with those including nonphysician providers (NPPs). We analyze results by rurality and compare findings with current health professional shortage areas.

DATA COLLECTION/EXTRACTION METHODS

Physicians and NPPs practicing in primary care in 2017 were extracted from the Iowa Health Professions Inventory.

PRINCIPAL FINDINGS

Considering only primary care physicians, the average unallocated population for primary care was 222 109 (7 percent of Iowa's population). Most of the unallocated population (86 percent) was in rural areas with low population density (< 50/square mile). The addition of NPPs to the primary care workforce reduced unallocated population by 65 percent to 78 252 (2.5 percent of Iowa's population). Despite the majority of NPPs being located in urban areas, most of the improvement in spatial accessibility (78 percent) is associated with sparsely populated rural areas.

CONCLUSIONS

The inclusion of nonphysician providers greatly reduces but does not eliminate all areas of inadequate spatial access to primary care.

Comparing quality of care in medical specialties between nurse practitioners and physicians

BACKGROUND

The American health care system is facing a growing health care provider shortage in primary and specialty care settings. Research has established that nurse practitioners (NPs) match or exceed their physician colleagues in providing quality care in primary care settings.

OBJECTIVE

This systematic review aimed to compare the quality of NP versus physician-led care in outpatient specialty care setting for clinical outcomes patient satisfaction.

DATA SOURCES

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement guided the literature search (CINAHL, PubMed, and Cochrane Library) and interpretation of findings. Of the 228 articles that met the inclusion/exclusion criteria, 11 were selected for further review.

CONCLUSIONS

Studies were conducted from 1995 to 2016 across four countries and spanned 10 distinct medical specialties. As a whole, these studies demonstrated that NPs in specialty settings perform as well as physicians terms of clinical safety and positive patient outcomes. Nurse practitioners matched or exceeded their physician counterparts in patient education and satisfaction.

IMPLICATIONS FOR PRACTICE

Nurse practitioners are a feasible option for addressing specialty care shortages. Further research should investigate whether NPs and physicians are equally prepared to provide equivalent care immediately following their respective postbaccalaureate programs. If not, studies should explore specific training duration and elements NPs require to provide equivalent care.

An investigation of the information technology needs associated with delivering chronic disease care to large clinical populations

BACKGROUND

The growing number of individuals with complex medical and social needs has motivated the adoption of care management (CM) - programs wherein multidisciplinary teams coordinate and monitor the clinical and non-clinical aspects of care for patients with chronic disease. Despite claims that health information technology (IT) is essential to CM, there has been limited research focused on the IT needs of clinicians providing care management to large groups of patients with chronic disease.

OBJECTIVE

To assess clinicians' needs pertaining to CM and to identify inefficiencies and bottlenecks associated with the delivery of CM to large groups of patients with chronic disease.

METHODS

A qualitative study of two HIV care programs. Methods included observations of multidisciplinary care team meetings and semi-structured interviews with physicians, care managers, and social workers. Thematic analysis was conducted to analyze the data.

RESULTS

CM was perceived by staff as requiring the development of novel strategies including patient prioritization and patient monitoring, which was supported by patient registries but also required the creation of additional homegrown tools. Common challenges included: limited ability to identify pertinent patient information, specifically in regards to social and behavioral determinants of health, limited assistance in matching patients to appropriate interventions, and limited support for communication within multidisciplinary care teams.

CONCLUSION

Clinicians delivering care management to chronic disease patients are not adequately supported by electronic health records and patient registries. Tools that better enable population monitoring, facilitate communication between providers, and help address psychosocial barriers to treatment could enable more effective care.

Cancer Survivorship Care Roles for Primary Care Physicians

PURPOSE

Despite a burgeoning population of cancer survivors and pending shortages of oncology services, clear definitions and systematic approaches for engaging primary care in cancer survivorship are lacking. We sought to understand how primary care clinicians perceive their role in delivering care to cancer survivors.

METHODS

We conducted digitally recorded interviews with 38 clinicians in 14 primary care practices that had national reputations as workforce innovators. Interviews took place during intense case study data collection and explored clinicians' perspectives regarding their role in cancer survivorship care. We analyzed verbatim transcripts using an inductive and iterative immersion-crystallization process.

RESULTS

Divergent views exist regarding primary care's role in cancer survivor care with a lack of coherence about the concept of survivorship. A few clinicians believed any follow-up care after acute cancer treatment was oncology's responsibility; however, most felt cancer survivor care was within their purview. Some primary care clinicians considered cancer survivors as a distinct population; others felt cancer survivors were like any other patient with a chronic disease. In further interpretative analysis, we discovered a deeply ingrained philosophy of whole-person care that creates a professional identity dilemma for primary care clinicians when faced with rapidly changing specialized knowledge.

CONCLUSIONS

This study exposes an emerging identity crisis for primary care that goes beyond cancer survivorship care. Facilitated national conversations might help specialists and primary care develop knowledge translation platforms to support the prioritizing, integrating, and personalizing functions of primary care for patients with highly complicated issues requiring specialized knowledge.

Supportive Clinical Practice Environments Associated With Patient-Centered Care

A lack of organizational supports in clinical settings may prevent nurse practitioners from providing patient centered care. Using a cross sectional survey design, data were collected from NPs in 1,571 practices across four states to investigate clinical practice environments and the extent to which they are associated with NP integration of patient preferences. Three-quarters of NPs reported frequent integration of patient preferences into clinical care. Overall, 371 practices (23.6%) were classified as good practice environments; the remaining 76.3% were mixed or poor environments. NPs in good environments were significantly more likely to integrate patient preferences (O.R. = 2.3, p <.001).

Redesigning the Role of Medical Assistants in Primary Care: Challenges and Strategies During Implementation

Efforts to reform primary care increasingly focus on redesigning care in ways that utilize nonprovider staff such as medical assistants (MAs), but the implementation of MA role redesign efforts remains understudied in the U.S. health care literature. This article draws on rich, longitudinal case study data collected from four health care systems across the United States to examine critical challenges in the planning, implementation, and early sustainment of MA role redesign efforts in primary care. During the planning period, challenges included recruitment of highly trained MAs, compliance with organizational and state regulations regarding MA scope of practice, provision of consistent training across primary care clinics, and creation of career ladders that provided tiered compensation for MAs. During active implementation, challenges included provider training and preventing MA burnout. Strategies for addressing challenges in MA role redesign efforts are discussed, as well as early sustainment of program practices and organizational policies.

Organization of Work Factors Associated with Work Ability among Aging Nurses

The United States (U.S.) workforce is aging. There is a paucity of literature exploring aging nurses' work ability. This study explored the work-related barriers and facilitators influencing work ability in older nurses. We conducted a qualitative descriptive study of aging nurses working in direct patient care (N = 17). Participants completed phone or in-person semi-structured interviews. We used a content analysis approach to analyzing the data. The overarching theme influencing the work ability of aging nurses was intrinsically motivated. This was tied to the desire to remain connected with patients at bedside. We identified factors at the individual, unit-based work level and the organizational level associated with work ability. Individual factors that were protective included teamwork, and feeling healthy and capable of doing their job. Unit-based level work factors included having a schedule that accommodated work-life balance, and one's chronotype promoted work ability. Organizational factors included management that valued worker's voice supported work ability.

Physician Use of Health Care Teams for Improving Quality in Primary Care

OBJECTIVES

Health care teams may be used to improve quality in the primary care setting. Absent in the extant literature on health care teams is knowledge of how physicians seek to deploy this innovation on an everyday basis to improve care quality. This study's aim was to explore how physicians use teams in practice to deliver higher-quality care.

METHODS

A qualitative study using data collected through 39 interviews with primary care physicians and 9 interviews with medical assistants, employed across different primary care settings in the northeastern region of the United States.

RESULTS

Physicians used teams for 2 care quality functions: "getting basic care duties off their plate" to have more time for complex care delivery and "as relational extensions" of themselves to enhance the patient experience and provide care continuity. Physicians identified the following ingredients for using teams for these functions: (a) achieving long-term continuity working with the same team members; (b) having the correct mix of personalities and skills sets on the team; and (c) a "who is doing what" focus in the team for achieving role clarity.

CONCLUSIONS

The findings illuminate how primary care physicians attempt to use teams to improve care quality and enhance their role as care providers.

Nurse Practitioner Practice Environments in Primary Care and Quality of Care for Chronic Diseases

BACKGROUND

The chronic disease burden in the United States represents a significant challenge for the primary care system. The nurse practitioner (NP) workforce can help meet the demand for care; however, organizational barriers such as poor practice environments prevent NPs from delivering high quality care.

OBJECTIVES

We investigated the relationship between NP practice environments and quality of care for chronic diseases.

RESEARCH DESIGN

We fit regression models to assess cross-sectional associations between claims-based quality measure performance and survey data on NP practice environments in Massachusetts.

SUBJECTS

We used survey data from 221 primary care NPs from 118 practices. We obtained quality of care data for patients with asthma, diabetes, and cardiovascular disease.

MEASURES

The Nurse Practitioner Primary Care Organizational Climate Questionnaire was used to measure practice environments with its following 4 subscales: NP-Physician Relations, Independent Practice and Support, Professional Visibility, and NP-Administration Relations. Three Healthcare Effectiveness Data and Information Set measures were used to evaluate the quality of care.

RESULTS

A 1-SD increase in the organizational-level NP-Administration Relations subscale score was associated with a near doubling of the odds of receiving medication management for asthma. A 1-SD increase in the organizational-level Independent Practice and Support subscale score was associated with a 60% increase in the odds of receiving recommended screening for cardiovascular disease. There was no impact on diabetes care measure.

CONCLUSIONS

NP practice environment affected the quality of care for 2 chronic conditions. Efforts should be implemented to improve NP practice environment to potentially improve care quality.

Impact of team configuration and team stability on primary care quality

Background

The science of effective teams is well documented; far less is known, however, about how specific team configurations may impact primary care team effectiveness. Further, teams experiencing frequent personnel changes (perhaps as a consequence of poor implementation) may have difficulty delivering effective, continuous, well-coordinated care. This study aims to examine the extent to which primary care clinics in the Veterans Health Administration have implemented team configurations consistent with recommendations based on the Patient-Centered Medical Home model and the extent to which adherence to said recommendations, team stability, and role stability impact healthcare quality. Specifically, we expect to find better clinical outcomes in teams that adhere to recommended team configurations, teams whose membership and configuration are more stable over time, and teams whose clinical manager role is more stable over time.

Methods/design

We will employ a combination of social network analysis and multilevel modeling to conduct a database review of variables extracted from the Veterans Health Administration’s Team Assignments Report (TAR) (one of the largest, most diverse existing national samples of primary care teams (n_teams > 7000)), as well as other employee and clinical data sources. To ensure the examination of appropriate clinical outcomes, we will enlist a team of subject matter experts to select a concise set of clear, prioritized primary care performance metrics. We will accomplish this using the Productivity Measurement and Enhancement System, an evidence-based methodology for developing and implementing performance measurement.

Discussion

We are unaware of other studies of healthcare teams that consider team size, composition, and configuration longitudinally or with sample sizes of this magnitude. Results from this study can inform primary care team implementation policy and practice in both private- and public-sector clinics, such that teams are configured optimally, with adequate staffing, and the right mix of roles within the team.

Differential Patterns of Referral to Neurosurgery: A Comparison of Allopathic Physicians, Osteopathic Physicians, Nurse Practitioners, Physician Assistants, and Chiropractors

BACKGROUND

Rising cost and limited resources remain major challenges to U.S. health care and neurosurgery in particular. To ensure an efficient and cost-effective health care system, it is important that referrals to neurosurgery clinics are appropriate, and that referred patients have a reasonably high probability of requiring surgical intervention or, at a minimum, ongoing neurosurgical follow-up. This retrospective study tests the null hypothesis that the probability of a referred patient requiring surgery is independent of referring provider credentials and referring service specialty.

METHODS

A database of all patients referred to the neurosurgery clinic from 2015 through 2018 (n = 5677) was reviewed; the database included referring provider, referring provider specialty, number of subsequent clinic visits, and outcome of surgery or no surgery. Associations between categorical variables were tested using a χ² analysis with post hoc relative risk (RR) calculations and binary logistical regression.

RESULTS

Compared with patients referred by allopathic physicians, patients referred by osteopathic physicians (RR, 0.63; 95% confidence interval [CI], 0.48-0.84) and those referred by nurse practitioners (RR, 0.66; 95% CI, 0.51-0.86) were significantly less likely to require surgery. Probability of surgical intervention also varied by referrer specialty. Patients referred by neurologists required surgery 35% of the time, whereas patients referred by family practitioners required surgery 19% of the time, and patients referred by pediatricians required surgery only 7% of the time (P < 0.01). Binary logistic regression revealed that referrals from nurse practitioners and osteopathic physicians were independently associated with a decreased probability of surgical intervention.

CONCLUSIONS

Our data strengthen the concept of having interdisciplinary teams led by physicians at the primary care level to ensure appropriate referrals. Training and adherence to guidelines must continually be reinforced to ensure proper referrals.

Quality of Primary Care Provided to Medicare Beneficiaries by Nurse Practitioners and Physicians

OBJECTIVE

To examine differences in the quality of care provided by primary care nurse practitioners (PCNPs), primary care physicians (PCMDs), or both clinicians.

DATA SOURCES

Medicare part A and part B claims during 2012-2013.

STUDY DESIGN

Retrospective cohort design using standard risk-adjustment methodologies and propensity score weighting assessing 16 claims-based quality measures grouped into 4 domains of primary care: chronic disease management, preventable hospitalizations, adverse outcomes, and cancer screening.

EXTRACTION METHODS

Continuously enrolled aged, disabled, and dual eligible beneficiaries who received at least 25% of their primary care services from a random sample of PCMDs, PCNPs, or both clinicians.

PRINCIPAL FINDINGS

Beneficiaries attributed to PCNPs had lower hospital admissions, readmissions, inappropriate emergency department use, and low-value imaging for low back pain. Beneficiaries attributed to PCMDs were more likely than those attributed to PCNPs to receive chronic disease management and cancer screenings. Quality of care for beneficiaries jointly attributed to both clinicians generally scored in the middle of the PCNP and PCMD attributed beneficiaries with the exception of cancer screening.

CONCLUSIONS

The quality of primary care varies by clinician type, with different strengths for PCNPs and PCMDs. These comparative advantages should be considered when determining how to organize primary care to Medicare beneficiaries.

Did Performing Community Health Needs Assessments Increase Community Health Program Spending by North Carolina's Tax-Exempt Hospitals?

As of March 23, 2012, the Internal Revenue Service (IRS) requires tax-exempt hospitals to conduct a Community Health Needs Assessment (CHNA) every 3 years. This study assessed whether the IRS CHNA mandate incentivized North Carolina's tax-exempt hospitals to increase investments in community health programs. The authors gathered the 2012-2016 community benefit reports of 53 North Carolina private, nonprofit hospitals from the North Carolina Hospital Association. Community benefit spending data from the year of the first CHNA were compared to that 2 years later using paired t tests among matched subjects. No significant increases were found in hospitals' community health programs spending (P = 0.6920) or in providing patient care financial assistance (charity or discounted care) (P = 0.0934). In fact, aggregate community health programs spending effectively decreased by 4%, from $393.3 million to $377.5 million. Among all community benefit items, only the unreimbursed cost for treating Medicare patients increased significantly (P = 0.0297). The proportion of spending on community health programs relative to patient care financial assistance decreased significantly (P = 0.0338). Performing CHNAs did not incentivize North Carolina's tax-exempt hospitals to progressively invest in community health programs. The hospitals continue to spend heavily on patient care financial assistance and little on disease prevention and community health improvement activities. These findings suggest that tax-exempt hospitals continue to function as a safety net for the poor and the uninsured rather than as active partners in population health management initiatives. At present, performing CHNAs may be more a demonstration of compliance than a tool to improve population health.

The workforce trends of physician assistants in Iowa (1995-2015)

BACKGROUND

Physician assistants are expected to have an important role in providing both primary and specialty care. Iowa has a large rural (and aging) population and faces challenges to provide equitable access to care. This study examined changes in the Iowa physician assistant workforce (1995-2015) focusing on practice setting (primary v. subspecialty care) and geographic location (rural/urban, Health Professional Shortage Area). Documenting their current locations and service in HPSAs for primary care will help health planners track future changes.

METHODS

Data from 1995-2015 from the Iowa Health Professions Inventory (Office of Statewide Clinical Education Programs, Carver College of Medicine, University of Iowa) were combined with US census data on rural location and HPSA status. SPSS was used to compare Iowa and national data. Growth trends were analyzed using joinpoint regression.

RESULTS

The overall Iowa physician assistant workforce increased 161% between 1995 and 2015. In 2015, more than two-thirds (71%) were female and more than 30% practiced in rural counties. The average annual growth rate of primary care PAs (per 100,000 population) was significantly higher in the periods from 1995-1997 and 1997-2001 (22.4% and 7.4% respectively) than in period from 2001-2015 (3.8%). By 2015, 56% of Iowa's physician assistants practiced in primary care (versus 29.6% nationally). Of these, 44% of primary care physician assistants in Iowa practiced in counties, geographic locations or worksites designated as Health Professional Shortage Areas for primary care.

CONCLUSIONS

A high proportion of Iowa's physician assistant workforce practiced in primary care and many served patients in Health Professional Shortage Areas. The number of physician assistants in Iowa will continue to grow and serve an important role in providing access to health care, particularly to rural Iowans.

Workforce Configurations to Provide High-Quality, Comprehensive Primary Care: a Mixed-Method Exploration of Staffing for Four Types of Primary Care Practices

BACKGROUND

Broad consensus exists about the value and principles of primary care; however, little is known about the workforce configurations required to deliver it.

OBJECTIVE

The aim of this study was to explore the team configurations and associated costs required to deliver high-quality, comprehensive primary care.

METHODS

We used a mixed-method and consensus-building process to develop staffing models based on data from 73 exemplary practices, findings from 8 site visits, and input from an expert panel. We first defined high-quality, comprehensive primary care and explicated the specific functions needed to deliver it. We translated the functions into full-time-equivalent staffing requirements for a practice serving a panel of 10,000 adults and then revised the models to reflect the divergent needs of practices serving older adults, patients with higher social needs, and a rural community. Finally, we estimated the labor and overhead costs associated with each model.

RESULTS

A primary care practice needs a mix of 37 team members, including 8 primary care providers (PCPs), at a cost of $45 per patient per month (PPPM), to provide comprehensive primary care to a panel of 10,000 actively managed adults. A practice requires a team of 52 staff (including 12 PCPs) at $64 PPPM to care for a panel of 10,000 adults with a high proportion of older patients, and 50 staff (with 10 PCPs) at $56 PPPM for a panel of 10,000 with high social needs. In rural areas, a practice needs 22 team members (with 4 PCPs) at $46 PPPM to serve a panel of 5000 adults.

CONCLUSIONS

Our estimates provide health care decision-makers with needed guideposts for considering primary care staffing and financing and inform broader discussions on primary care innovations and the necessary resources to provide high-quality, comprehensive primary care in the USA.

Spatial Accessibility of Primary Care in England: A Cross-Sectional Study Using a Floating Catchment Area Method

OBJECTIVE

To analyze the general practitioners (GPs) with regard to the degree of urbanization, social deprivation, general health, and disability.

DATA SOURCES

Small area population data and GP practice data in England.

STUDY DESIGN

We used a floating catchment area method to measure spatial GP accessibility with regard to the degree of urbanization, social deprivation, general health, and disability.

DATA COLLECTION

Data were collected from the Office for National Statistics and the general practice census and analyzed using a geographic information system.

PRINCIPAL FINDINGS

In all, 25.8 percent of the population in England lived in areas with a significant low GP accessibility (mean z-score: -4.2); 27.6 percent lived in areas with a significant high GP accessibility (mean z-score: 7.7); 97.8 percent of high GP accessibility areas represented urban areas, and 31.1 percent of low GP accessibility areas represented rural areas (correlation of accessibility and urbanity: r = 0.59; p<.001). Furthermore, a minor negative correlation with social deprivation was present (r = -0.19; p<.001). Results were confirmed by a multivariate analysis.

CONCLUSION

This study showed substantially differing GP accessibility throughout England. However, socially deprived areas did not have poorer spatial access to GPs.

Patient characteristics associated with primary care PA and APRN roles

OBJECTIVES

Physician assistants (PAs) and advanced practice registered nurses (APRNs) can perform multiple roles on primary care teams, but limited research describes the patients they serve. We sought to identify patient characteristics associated with roles of primary care PAs and APRNs.

METHODS

We analyzed adult respondents to the 2010 Health Tracking Household Survey with a primary care usual provider (physician, PA, or APRN). The dependent variable is the PA or APRN role. Explanatory variables include sociodemographic characteristics, attitudes toward use, delayed care, and perceived health.

RESULTS

Compared with respondents seen by physicians only, respondents seen by a PA or APRN in any role were more likely to be younger, female, living in rural areas, and put off needed medical care. Respondents seen by a PA or APRN as their usual provider were more likely to report better health. Patients seen by a PA or APRN in a supplemental role reported being sicker, more educated, and attitudinally less likely to use healthcare.

CONCLUSIONS

PAs and APRNs perform different roles for different types of patients.

NP and PA Privileging in Acute Care Settings: Do Scope of Practice Laws Matter?

As hospitals’ interest in nurse practitioners (NPs) and physician assistants (PAs) grows, their leadership is eager to know how their medical staffing privileging policies for these professionals compare to peer hospitals. This study assesses the extent of variation of these policies in four clinical areas and examines whether the differences are associated with state scope of practice laws for NPs and PAs. We also examine the relationship of NP and PA privileging policies to each other. Our analysis finds no evidence that hospital privileging is associated with state scope of practice, and indeed within-state variation is more significant than cross-state variation. We also find a strong correlation between NP and PA privileging in all four clinical areas. These results suggest the need for additional research to understand the institutional-level variables and human dynamics at the level of medical staffing committees that may explain the dramatic variation in privileging policies and, ultimately, the effects of different privileging levels on costs and quality.

Use of Acupuncture in the United States Military Healthcare System

Objectives: The Military Healthcare System (MHS) shows increasing interest in acupuncture as an alternative to opioids for pain control. However, specific factors associated with this procedure in the MHS are not well-described in literature. This study examines usage within the MHS to determine patterns among the diagnoses, provider types, and facilities associated with acupuncture. Materials and Methods: Acupuncture-treated patients were identified from TRICARE claims data in the MHS Data Repository as having at least one acupuncture treatment in fiscal year (FY) 2014. Bivariate analysis was performed to determine demographics, diagnoses, and number of visits, for both active-duty and nonactive-duty personnel. Descriptive statistics were used to show associated provider and facility types. Results: A total of 15,761 people received acupuncture in the MHS in FY 2014. Use of acupuncture was greater for Army service, white race, and senior enlisted rank overall, and for males ages 26-35 among active-duty and females ages 46-64 among nonactive-duty beneficiaries. A cumulative 76% of diagnoses were for musculoskeletal or nerve and system issues. Approximately 60% of patients received acupuncture from physicians, 16% from physical therapists or chiropractors, and 9.7% from physician extenders. Specific acupuncture techniques (traditional, auricular, etc.) could not be determined from the data set. Conclusions: The most common diagnoses associated with acupuncture are consistent with pain management. However, full analysis is hampered by inconsistent coding and lack of granularity regarding specific techniques. Given the popularity of acupuncture in the MHS, further research is necessary to explore the full scope of this intervention.

Association of State-Level Restrictions in Nurse Practitioner Scope of Practice With the Quality of Primary Care Provided to Medicare Beneficiaries

Context: State scope of practice (SoP) laws impose significant restrictions on the services that a nurse practitioner (NP) may provide in some states, yet evidence about SoP limitations on the quality of primary care is very limited. Method: This study uses six different classifications of state regulations and bivariate and multivariate analyses to compare beneficiaries attributed to primary care nurse practitioners and primary care physicians in 2013 testing two hypotheses: (1) chronic disease management, cancer screening, preventable hospitalizations, and adverse outcomes of care provided by primary care nurse practitioners are better in reduced and restricted practice states compared to states without restrictions and (2) by decreasing access to care, SoP restrictions negatively affect the quality of primary care. Findings: Results show a lack of consistent association between quality of primary care provided by NPs and state SoP restrictions. Conclusion: State regulations restricting NP SoP do not improve the quality of care.

Nurse practitioners as primary care providers with their own patient panels and organizational structures: A cross-sectional study

BACKGROUND

Health care systems globally are facing challenges of meeting the growing demand for primary care services due to a shortage of primary care physicians. Policy makers and administrators are searching for solutions to increase the primary care capacity. The effective utilization of nurse practitioners (NPs) has been proposed as a solution. However, organizations utilize NPs in variable capacities. In some settings, NPs serve as primary care providers delivering ongoing continuous care to their patients, referred to as patient panels, whereas in other settings they deliver episodic care. Little is known about why organizations deploy NPs differently.

OBJECTIVES

Investigate the NP role in care delivery-primary care providers with the own patient panels or delivering episodic care-within their organizations and understand how work environments affect their role.

DESIGN

A cross-sectional survey design was used to collect data from primary care NPs.

SETTINGS

The study was conducted in one state in the United States (Massachusetts). Data from 163 primary care organizations was obtained, which employed between one to 12 NPs.

PARTICIPANTS

807 NPs recruited from the Massachusetts Provider Database received mail surveys; 314 completed and returned the survey, yielding a response rate of 40%.

METHODS

The survey contained measures of NP role in care delivery and work environment. NP role was measured by an item asking NPs to report if they deliver ongoing continuous care to their patient panel or if they do not have patient panel. The work environment was measured with the Nurse Practitioner Primary Care Organizational Climate Questionnaire (NP-PCOCQ). The multilevel Cox regression models investigated the influence of organization-level work environment on NP role in care delivery.

RESULTS

About 45% of NPs served as primary care providers with their own patient panel. Organization-level Independent Practice and Support subscale, an NP-PCOCQ subscale, had a significant positive effect on NP role (risk ratio=2.33; 95% CI: 1.06-5.13); with a one unit increase on this subscale, the incidence of the NPs serving as primary care providers with their own patient panel doubled.

CONCLUSIONS

NPs can help meet the increasing demand for primary care by taking responsibilities as primary care providers, and organizations can assign NPs their own patient panels. Supporting NP independent practice within organizations promotes NP role as primary care providers. Policy and organizational change focused on promoting NP work environments so NPs can practice as primary care providers can be an effective strategy to increase the primary care capacity.

Expanded roles of registered nurses in primary care delivery of the future

BACKGROUND

Primary care in the United States is changing: practice size is increasing, there is a growing shortage of primary care practitioners, and there is a heightened prevalence of chronic disease. Given these trends, it is likely that registered nurses will become important members of the primary care team.

PURPOSE

This paper explores the challenges and opportunities in primary care delivery in the 21st century and examines the likelihood of expanded roles for RNs to improve quality and add capacity to the primary care workforce.

METHODS

We searched the peer-reviewed and gray literature for publications on primary care, primary care workforce projections, the future of nursing, and team-based care.

DISCUSSION

The number of primary care physicians is expected to decrease in relation to the US population while the number of nurse practitioners is increasing, with the result that more and more patients will see nurse practitioners as their primary care practitioner. However, the primary care practitioner (physicians, nurse practitioners and physician assistants) to population ratio is dropping. As a result, other professionals will be needed to deliver primary care. As the nation's largest health profession, registered nurses (RNs) are in sufficient supply and have been shown to improve the care of patients with chronic conditions. It is likely that primary care practices of the future will include an enhanced role for RNs, particularly in chronic disease management.

CONCLUSION

For RNs to assume an expanded role in primary care, several barriers need to be overcome: (1) the widespread introduction of payment reform that reimburses RNs to independently provide care for patients, and (2) nursing education reform that includes primary care nursing skills (3) scope of practice clarification for non-advance practice RNs working under standardized procedures.

Nurse-Related Clinical Nonlicensed Personnel in U.S. Hospitals and Their Relationship with Nurse Staffing Levels

OBJECTIVE

This study examines nurse-related clinical nonlicensed personnel (CNLP) in U.S. hospitals between 2010 and 2014, including job categories, trends in staffing levels, and the possible relationship of substitution between this group of workers and registered nurses (RNs) and/or licensed practical nurses (LPNs).

DATA SOURCE

We used 5 years of data (2010-2014) from an operational database maintained by Premier, Inc. that tracks labor hours, hospital units, and facility characteristics.

STUDY DESIGN

We assessed changes over time in the average number of total hours worked by RNs, LPNs, and CNLP, adjusted by total patient days. We then conducted linear regressions to estimate the relationships between nurse and CNLP staffing, controlling for patient acuity, volume, and hospital fixed effects.

PRINCIPAL FINDINGS

The overall use of CNLP and LPN hours per patient day declined from 2010 to 2014, while RN hours per patient day remained stable. We found no evidence of substitution between CNLP and nurses during the study period: Nurse-related CNLP hours were positively associated with RN hours and not significantly related to LPN hours, holding other factors constant.

CONCLUSIONS

Findings point to the importance of examining where and why CNLP hours per patient day have declined and to understanding of the effects of these changes on outcomes.

A Rural "Grow Your Own" Strategy: Building Providers From the Local Workforce

Rural health care leaders are increasingly tasked with the responsibility of providing health access to 21% of the national population with only 10% of the provider workforce. Provider recruitment strategies offering loan repayment have had some success in the short term but are less impactful at creating a long-term retention rate, unless the providers have an existing connection to either the community in which they are working or rural health care. Responding to these data, a demonstration project and study has been underway in Colorado to test a rural focused "grow your own" advanced practice registered nurse (APRN) model. Phase 1 is designed to measure recruitment of RNs from inside rural communities to return to school and become primary care providers within those communities. Phase 2 will measure completion of education and phase 3 will measure retention rates in those communities. This article reports on phase 1 of the project, which is recruitment. The project offers stipend support with assistance in the school application process, educational support, clinical and job placement assistance, and monthly coaching. In addition, communities were asked to provide matching funds to support the APRN students with a goal of creating a self-sustaining model that will build a continuous pipeline of APRN providers. This strategy avoids the costly need to recruit and relocate providers who have no ties to the community. Thirty-four of 36 nurses (94%) responded to the study survey. Survey results suggested that the combination of financial, community, and employer support utilized in this model could serve to create a new and sustainable strategy for building a rural APRN provider workforce pipeline. The ultimate outcome has the potential to ensure that all people in rural areas have access to a high-quality, well-educated primary care provider.

General practitioners in German metropolitan areas - distribution patterns and their relationship with area level measures of the socioeconomic status

BACKGROUND

Geographical variation of the general practitioner (GP) workforce is known between rural and urban areas. However, data about the variation between and within urban areas are lacking.

METHOD

We analyzed distribution patterns of GP full time equivalents (FTE) in German cities with a population size of more than 500,000. We correlated their distribution with area measures of social deprivation in order to analyze preferences within neighborhood characteristics. For this purpose, we developed two area measures of deprivation: Geodemographic Index (GDI) and Cultureeconomic Index (CEI).

RESULTS

In total n = 9034.75 FTE were included in n = 14 cities with n = 171 districts. FTE were distributed equally on inter-city level (mean: 6.49; range: 5.12-7.20; SD: 0.51). However, on intra-city level, GP distribution was skewed (mean: 6.54; range: 1.80-43.98; SD: 3.62). Distribution patterns of FTE per 10^4 residents were significantly correlated with GDI (r = -0.49; p < 0.001) and CEI (r = -0.22; p = 0.005). Therefore, location choices of GPs were mainly positively correlated with 1) central location (r = -0.50; p < 0.001), 2) small household size of population (r = -0.50; p < 0.001) and 3) population density (r = 0.35; p < 0.001).

CONCLUSION

Intra-city distribution of GPs was skewed, which could affect the equality of access for the urban population. Furthermore, health services planners should be aware of GP location preferences. This could be helpful to better understand and plan delivery of health services. Within this process the presented Geodemographic Index (GDI) could be of use.

To What Extent Are State Scope of Practice Laws Related to Nurse Practitioners’ Day-to-Day Practice Autonomy?

We explore the extent to which state scope of practice laws are related to nurse practitioners (NPs)’ day-to-day practice autonomy. We found that NPs experienced greater day-to-day practice autonomy when they had prescriptive independence. Surprisingly, there were only small and largely insignificant differences in day-to-day practice autonomy between NPs in fully restricted states and those in states with independent practice but restricted prescription authority. The scope of practice effects were strong for primary care NPs. We also found that the amount of variation in day-to-day practice autonomy within the scope of practice categories existed, which suggests that factors other than state scope of practice laws may influence NP practice as well. Removing barriers at all levels that potentially prevent NPs from practicing to the full extent of their education and training is critical not only to increase primary care capacity but also to make NPs more efficient and effective providers.

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.
