Nurse Practitioner Care Environments and Racial and Ethnic Disparities in Hospitalization Among Medicare Beneficiaries with Coronary Heart Disease.

BACKGROUND: Nurse practitioners care for patients with cardiovascular disease, particularly those from racial and ethnic minority groups, and can help assure equitable health outcomes. Yet, nurse practitioners practice in challenging care environments, which limits their ability to care for patients. OBJECTIVE: To determine whether primary care nurse practitioner care environments are associated with racial and ethnic disparities in hospitalizations among older adults with coronary heart disease. DESIGN: In this observational study, a cross-sectional survey was conducted among primary care nurse practitioners in 2018-2019 who completed a valid measure of care environment. The data was merged with 2018 Medicare claims data for patients with coronary heart disease. PARTICIPANTS: A total of 1244 primary care nurse practitioners and 180,216 Medicare beneficiaries 65 and older with coronary heart disease were included. MAIN MEASURES: All-cause and ambulatory care sensitive condition hospitalizations in 2018. KEY RESULTS: There were 50,233 hospitalizations, 9068 for ambulatory care sensitive conditions. About 28% of patients had at least one hospitalization. Hospitalizations varied by race, being highest among Black patients (33.5%). Care environment moderated the relationship between race (Black versus White) and hospitalization (OR 0.93; 95% CI, 0.88-0.98). The lowest care environment was associated with greater hospitalization among Black (odds ratio=1.34; 95% CI, 1.20-1.49) compared to White beneficiaries. Practices with the highest care environment had no racial differences in hospitalizations. There was no interaction effect between care environment and race for ambulatory care sensitive condition hospitalizations. Nurse practitioner care environment had a protective effect on these hospitalizations (OR, 0.96; 95% CI, 0.92-0.99) for all beneficiaries. CONCLUSIONS: Unfavorable care environments were associated with higher hospitalization rates among Black than among White beneficiaries with coronary heart disease. Racial disparities in hospitalization rates were not detected in practices with high-quality care environments, suggesting that improving nurse practitioner care environments could reduce racial disparities in hospitalizations.

Acute Care Use Among Patients with Multiple Chronic Conditions Receiving Care from Nurse Practitioner Practices in Health Professional Shortage Areas.

BACKGROUND: Patients with multiple chronic conditions often have many care plans, polypharmacy, and unrelieved symptoms that contribute to high emergency department and hospital use. High-quality primary care delivered in practices that employ nurse practitioners can help prevent the need for such acute care services. However, such practices located in primary care health professional shortage areas face challenges caring for these patients due to higher workloads and fewer resources. OBJECTIVE: We examined differences in hospitalization and emergency department use among patients with multiple chronic conditions who receive care from practices that employ nurse practitioners in health professional shortage areas compared to practices that employ nurse practitioners in non-health professional shortage areas. METHODS: We performed an analysis of Medicare claims, merged with Health Resources and Services Administration data on health professional shortage area status in five states. Our sample included 394,424 community-dwelling Medicare beneficiaries aged ≥65 with at least two of 15 common chronic conditions who received care in 779 practices that employ nurse practitioners. We used logistic regression to assess the relationship between health professional shortage area status and emergency department visits or hospitalizations. RESULTS: We found a higher likelihood of emergency department visits among patients in health professional shortage areas compared to those in non-health professional shortage areas, and no difference in the likelihood of hospitalization. DISCUSSION: Emergency department use differences exist among older adults with multiple chronic conditions receiving care in practices that employ nurse practitioners in health professional shortage areas, compared to those in non-health professional shortage areas. To address this disparity, the health professional shortage area program should invest in recruiting and retaining nurse practitioners to health professional shortage areas to ease workforce shortages.

Burnout, job satisfaction, and turnover intention among primary care nurse practitioners with their own patient panels.

BACKGROUND: Nurse practitioners (NPs) can enhance NP care and improve access to care by autonomously managing their patient panels. Yet, its impact on workforce outcomes such as burnout, job satisfaction, and turnover intention remains unexplored. PURPOSE: To estimate the impact of NP panel management on workforce outcomes. METHODS: Structural equation modeling was conducted using survey data from 1,244 primary care NPs. NP panel management was categorized into co-managing patients with other providers, both co-managing and autonomously managing, and fully autonomous management. DISCUSSION: Fully autonomous management led to more burnout than co-managing (B = 0.089, bias-corrected 95% bootstrap confidence interval [0.028, 0.151]). Work hours partially (27%) mediated this relationship. This findings indicate that greater autonomy in panel management among NPs may lead to increased burnout, partially due to longer work hours. CONCLUSION: Interventions to reduce work hours could help NPs deliver quality care without burnout.

The Perspectives of Advanced Practice Provider Directors on Acute Care Nurse Practitioner Alignment and Hiring.

Demand for acute care is forecasted to grow in the United States. To meet this demand, nurse practitioners (NPs) are increasingly employed in acute care settings. Yet, there is concern about an adequate supply of acute care NPs given demand. Further, professional nursing organizations recommend aligning an NP's role with their education, certification, licensure, and practice. Given workforce constraints and the policy environment, little is known about how hospitals approach hiring NPs for acute care roles. The purpose of this study was to explore advanced practice provider (APP) directors' approaches to hiring NPs within the context of alignment and describe factors that influence hiring decisions. We conducted semi-structured interviews with 17 APP directors in hospitals and health systems. Interviews were recorded, transcribed, and coded using an iterative, hybrid inductive and deductive method. Two themes emerged: (1) local factors that inform aligned hiring and (2) adaptive hiring responses to changing environments. Practices around hiring NPs varied across institutions influenced by organization and state policies and regulations, workforce availability, and institutional culture. Most APP directors recognized trends towards hiring aligned NPs for acute care roles. However, they also identified barriers to fully aligning their NP workforce and described adaptive strategies including hiring physician assistants, building relationships with APP schools, and leveraging hospital resources to develop the APP workforce to meet care delivery demands given the current NP workforce supply. Future research is needed to assess widespread practices around acute care NP alignment and the implications of alignment for patient and organizational outcomes.

Risk of Hospitalization Associated with Use of Consumer-Directed Attendant Care.

Older people with disabilities living independently often use attendant care, also known as Personal Assistive Services (PAS). The aides providing care can come from a home health agency contracted by the state Medicaid authority, known as agency-directed PAS, or the Medicaid recipient can receive a monthly budget and arrange their own care, known as consumer-directed care. Consumer-directed care is hypothesized to have some possible benefits but could also potentially lead to health hazards. This study examined whether people receiving consumer-directed PAS versus people receiving agency-directed PAS faced a higher risk of hospitalization. The data for this study came from Pennsylvania Medicaid claims, enrollment files, standardized assessments, and hospitalization claims from Medicare and Medicaid. The analysis used two-stage least square regression, with the percentage of people in a county using consumer-directed care as an instrument for the type of PAS. People using consumer-directed care did not have a statistically significant difference in risk for hospitalization compared to people using agency-directed PAS (p = .976). Risk of hospitalization was not different for people using consumer-directed care compared to people using agency-directed care.

The Impact of Primary Care Practice Structural Capabilities on Nurse Practitioner Burnout, Job Satisfaction, and Intent to Leave.

BACKGROUND: Lack of structure for care delivery (ie, structural capabilities) has been linked to lower quality of care and negative patient outcomes. However, little research examines the relationship between practice structural capabilities and nurse practitioner (NP) job outcomes. OBJECTIVES: We investigated the association between structural capabilities and primary care NP job outcomes (ie, burnout, job dissatisfaction, and intent to leave). RESEARCH DESIGN: Secondary analysis of 2018-2019 cross-sectional data. SUBJECTS: A total of 1110 NPs across 1002 primary care practices in 6 states. MEASURES: We estimated linear probability models to assess the association between structural capabilities and NP job outcomes, controlling for NP work environment, demographics, and practice features. RESULTS: The average structural capabilities score (measured on a scale of 0-1) across practices was 0.6 (higher score indicates more structural capabilities). After controlling for potential confounders, we found that a 10-percentage point increase in the structural capabilities score was associated with a 3-percentage point decrease in burnout ( P <0.001), a 2-percentage point decrease in job dissatisfaction ( P <0.001), and a 3-percentage point decrease in intent to leave ( P <0.001). CONCLUSIONS: Primary care NPs report lower burnout, job dissatisfaction, and intent to leave when working in practices with greater structural capabilities for care delivery. These findings suggest that efforts to improve structural capabilities not only facilitate effective care delivery and benefit patients but they also support NPs and strengthen their workforce participation. Practice leaders should further invest in structural capabilities to improve primary care provider job outcomes.

DNP preparation of primary care nurse practitioners and clinical outcomes for patients with chronic conditions.

BACKGROUND: Many professional nursing organizations have proposed that the Doctor of Nursing Practice (DNP) is the most appropriate entry-level degree for nurse practitioners (NPs). There have been no studies to date examining the impact of DNP preparation on quality of care or patient outcomes. PURPOSE: To examine differences in emergency department utilization and hospitalizations among patients with chronic conditions cared for by Master of Science in Nursing (MSN)- and DNP-prepared primary care NPs. METHODS: We use survey data from over 1,000 primary care NPs in 6 states linked to Medicare claims data. Using regression models, we controlled for various patient, NP, and practice characteristics that might confound the relationship. RESULS: We find that patient outcomes are not statistically different between patients attributed to MSN- and DNP-prepared primary care NPs. DISCUSSION: These findings suggest that there remains little evidence that DNP education has led to significant improvements in patient outcomes. CONCLUSIONS: Further empirical analysis related to the clinical outcomes other than health care utilization of the DNP degree is warranted. Future studies might consider examining (a) NPs in settings other than primary care, (b) practice-wide or system-wide outcomes, (c) other measures of care quality, and (d) impact of DNP program content.

Describing the male registered nursing workforce toward increasing male representation in professional nursing.

BACKGROUND: Men are significantly underrepresented in nursing and increasing their numbers should be a priority. PURPOSE: To describe the male nursing workforce in terms of size, demographics, education, and work settings. METHODS: Using data from the 2018 National Sample Survey of Registered Nurses, we performed a secondary descriptive analysis. FINDINGS: We find that 9.6% of registered nurses are men. Men are more likely than women to hold an associate degree and clinical doctorates, be nurse anesthetists and supervisors, and work in emergency settings but less likely than females to participate in teaching. DISCUSSION: To increase male representation in nursing we must simultaneously rearticulate what it means for a job to be "female" while also showing that nursing incorporates many skills and interests traditionally coded as "male." We can also show men that nursing offers appealing employment that can lead to a deeply fulfilling personal and professional life.

Advancement of research on nurse practitioners: Setting a research agenda.

BACKGROUND: Primary care delivered by nurse practitioners (NPs) helps to meet the United States' growing demand for care and improves patient outcomes. Yet, barriers impede NP practice. Knowledge of these barriers is limited, hindering opportunities to eliminate them. PURPOSE: We convened a 1.5-day conference to develop a research agenda to advance evidence on the primary care NP workforce. METHODS: Thirty experts gathered in New York City for a conference in 2022. The conference included plenary sessions, small group discussions, and a prioritization process to identify areas for future research and research questions. DISCUSSION: The research agenda includes top-ranked research questions within five categories: (a) policy regulations and implications for care, quality, and access; (b) systems affecting NP practice; (c) health equity and the NP workforce; (d) NP education and workforce dynamics, and (e) international perspectives. CONCLUSION: The agenda can advance evidence on the NP workforce to guide policy and practice.

Primary Care Nurse Practitioner Work Environments and Hospitalizations and ED Use Among Chronically Ill Medicare Beneficiaries.

BACKGROUND: Nurse practitioners (NPs) play a critical role in delivering primary care, particularly to chronically ill elderly. Yet, many NPs practice in poor work environments which may affect patient outcomes. OBJECTIVE: We investigated the relationship between NP work environments in primary care practices and hospitalizations and emergency department (ED) use among chronically ill elderly. RESEARCH DESIGN: We used a cross-sectional design to collect survey data from NPs about their practices. The survey data were merged with Medicare claims data. SUBJECTS: In total, 979 primary care practices employing NPs and delivering care to chronically ill Medicare beneficiaries (n=452,931) from 6 US states were included. MEASURES: NPs completed the Nurse Practitioner-Primary Care Organizational Climate Questionnaire-a valid and reliable measure for work environment. Data on hospitalizations and ED use was obtained from Medicare claims. We used Cox regression models to estimate risk ratios. RESULTS: After controlling for covariates, we found statistically significant associations between practice-level NP work environment and 3 outcomes: Ambulatory Care Sensitive (ACS) ED visits, all-cause ED visits, and all-cause hospitalizations. With a 1-unit increase in the work environment score, the risk of an ACS-ED visit decreased by 4.4% [risk ratio (RR)=0.956; 99% confidence interval (CI): 0.918-0.995; P=0.004], an ED visit by 3.5% (RR=0.965; 99% CI: 0.933-0.997; P=0.005), and a hospitalization by 4.0% (RR=0.960;99% CI: 0.928-0.993; P=0.002). There was no relationship between NP work environment and ACS hospitalizations. CONCLUSION: Favorable NP work environments are associated with lower hospital and ED utilization. Practice managers should focus on NP work environments in quality improvement strategies.

Association of Team-Based Care and Continuity of Care with Hospitalizations for Veterans with Comorbid Mental and Physical Health Conditions.

BACKGROUND: Integrating mental health in primary care settings is associated with improved screening and detection of mental illness. In 2010, the Veterans Health Administration launched a patient-centered medical home (PCMH) model nationally across all clinical sites that integrated mental health into primary care-the Patient Aligned Care Team (PACT) initiative. Team-based delivery of continuous primary and mental health care, as found in effective collaborative care models, is thought to be crucial to managing veterans with mental health disorders. The association between clinic implementation of specific aspects of PACT and clinical outcomes of veterans with mental health disorders remains unknown. OBJECTIVE: To examine the association between clinic implementation of team-based care and continuity of care and subsequent hospitalizations among veterans with mental health disorders. DESIGN: Retrospective cohort study. PATIENTS: A total of 1,444,942 veterans with comorbid mental health disorders and physical health conditions receiving primary care in 831 VA PACT clinics in fiscal year (FY) 2015. MAIN MEASURES: We examined the clinic-level implementation of team-based care and continuity of care in the clinic where veterans received their primary care. Our primary outcome was any hospitalization in the VA or fee-based service in FY2016. We examined the impact of clinic-level implementation of team-based care and continuity of care on having a hospitalization, adjusting for patient demographic, clinical characteristics, and facility characteristics. KEY RESULTS: Veterans receiving care in clinics with the greatest versus lowest quartile of implementation of team-based care had lower rates of hospitalization (8.8% vs. 12.3%; adjusted OR = 0.92, 95% CI 0.85-0.99, p < 0.035). There was not a statistically significant association between clinic-level implementation of continuity of care and hospitalization. CONCLUSIONS: Veterans receiving care in clinics with greater implementation of team-based care had statistically significant lower rates of hospitalization.

Advanced practice nurse work environments and job satisfaction and intent to leave: Six-state cross sectional and observational study.

AIMS: To explore the relationship between nurse practitioner work environment and nurse practitioner outcomes (job satisfaction and intent to leave) in the United States. DESIGN: The study used a cross-sectional survey design to collect survey data from primary care nurse practitioners in six states in the United States. METHODS: We sent mail surveys to 5689 eligible nurse practitioners in Arizona, New Jersey, Washington, Pennsylvania, California and Texas. The mail also contained an online link. Participants could complete either the paper or online questionnaire. In total, 1244 participants completed the survey in 2018-2019. The work environment was measured using the Nurse Practitioner-Primary Care Organizational Climate Questionnaire comprised of four subscales: Nurse Practitioner-Administration Relations, Nurse Practitioner-Physician Relations, Independent Practice and Support and Professional Visibility. Global items measured job satisfaction and intent to leave. We used mixed-effect proportional-odds cumulative logit models to assess the association between work environment and job satisfaction and intent to leave. RESULTS: Overall, 90% of participants were either very satisfied or somewhat satisfied with their job and 22% reported intent to leave their job in 1 year. With a one-unit increase in the organizational-level Nurse Practitioner-Administration Relations score, the odds of having a higher job satisfaction level increased by about four times and the odds of intent to leave job decreased by about 60%. A higher organizational-level Nurse Practitioner-Physician Relations score was significantly associated with higher job satisfaction and lower odds of intent to leave. CONCLUSION: Improvements in work environments may improve nurse practitioner job satisfaction and retention. IMPACT: This study examined the relationship between work environment, job satisfaction and turnover intention of nurse practitioners. Better work environment is associated with higher job satisfaction and lower turnover intention. Findings have implications for clinical leadership who can take actions to create better work environments to increase the nurse practitioner workforce capacity.

State-level scope of practice regulations for nurse practitioners impact work environments: Six state investigation.

Nurse practitioner (NP) scope of practice (SOP) policies are different across the United States. Little is known about their impact on NP work environment in healthcare organizations. We investigated the association between SOP policies and organizational-level work environment of NPs. Through a cross-sectional survey design, data were collected from 1244 NPs in six states with variable SOP regulations (Arizona, New Jersey, Washington, Pennsylvania, Texas, and California) in 2018-2019. Arizona and Washington had full SOP-NPs had full authority to deliver care. New Jersey and Pennsylvania had reduced SOP with physician collaboration requirement; California and Texas had restricted SOP with physician supervision requirement. NPs completed mail or online surveys containing the Nurse Practitioner Primary Care Organizational Climate Questionnaire, which has these subscales: NP-Administration Relations (NP-AR), NP-Physician Relations (NP-PR), Independent Practice and Support (IPS), and Professional Visibility (PV). Regression models assessed the relationship between state-level SOP and practice-level NP work environment. NP-AR scores were higher in full SOP states compared to reduced (ß = 0.22, p < 0.01) and restricted (ß = 0.15, p < 0.01) SOP states. Similarly, IPS scores were higher in full SOP states. The PV scores were also higher in full SOP states compared to reduced (ß = 0.16, p < 0.001) and restricted (ß = 0.12, p < 0.05) SOP states. There was no relationship between SOP and NP-PR score. State-level policies affect NP work environment. In states with more favorable policies, NPs have better relationships with administration and report more role visibility and support. Efforts should be made to remove unnecessary SOP restrictions.

Association between physician practice Medicaid acceptance and employing nurse practitioners and physician assistants: A longitudinal analysis.

BACKGROUND: Access to care is often a challenge for Medicaid beneficiaries due to low practice participation. As demand increases, practices will likely look for ways to see Medicaid patients while keeping costs low. Employing nurse practitioners (NPs) and physician assistants (PAs) is one low-cost and effective means to achieve this. However, there are no longitudinal studies examining the relationship between practice Medicaid acceptance and NP/PA employment. PURPOSE: The purpose of this study was to examine the association of practice Medicaid acceptance with NP/PA employment over time. METHODS: Using SK&A data (2009-2015), we constructed a panel of 102,453 unique physician practices to assess for changes in Medicaid acceptance after newly employing NPs and PAs. We employed practice-level fixed effects linear regressions. RESULTS: Our results showed that, among practices employing both NPs and PAs, there was a roughly 2% increase in the likelihood of Medicaid participation over time. When stratifying our sample by practice size and specialty, the positive correlation localized to small primary care and medical practices. When both NPs and PAs were present, small primary care practices had a 3.3% increase and small medical practices had a 6.9% increase in the likelihood of accepting Medicaid. CONCLUSION: NP and PA employment was positively associated with increases in Medicaid participation. PRACTICE IMPLICATIONS: As more individuals gain coverage under Medicaid, organizations will need to decide how to adapt to greater patient demand. Our results suggest that hiring NPs and PAs may be a potential lower cost strategy to accommodate new Medicaid patients.

State responses to COVID-19: Potential benefits of continuing full practice authority for primary care nurse practitioners.

BACKGROUND: During the COVID-19 pandemic, federal and state governments removed the scope of practice restrictions on nurse practitioners (NPs), allowing them to deliver care to patients without restrictions. PURPOSE: To support policy makers' efforts to grant full practice authority to NPs beyond the COVID-19 pandemic, this manuscript summarizes the existing evidence on the benefits of permanently removing state-level scope of practice barriers and outline recommendations for policy, practice, and research. METHODS: We have conducted a thorough review of the existing literature. FINDINGS: NP full scope of practice improves access and quality of care and leads to better patient outcomes. It also has the potential to reduce health care cost. DISCUSSION: The changes to support full practice authority enacted to address COVID-19 are temporary. NP full practice authority could be part of a longer-term plan to address healthcare inequities and deficiencies rather than merely a crisis measure.

Advanced Practice Provider-inclusive Staffing Models and Patient Outcomes in Pediatric Critical Care.

BACKGROUND: Pediatric intensive care units (PICUs) are increasingly staffed with advanced practice providers (APPs), supplementing traditional physician staffing models. OBJECTIVES: We evaluate the effect of APP-inclusive staffing models on clinical outcomes and resource utilization in US PICUs. RESEARCH DESIGN: Retrospective cohort study of children admitted to PICUs in 9 states in 2016 using the Healthcare Cost and Utilization Project's State Inpatient Databases. PICU staffing models were assessed using a contemporaneous staffing survey. We used multivariate regression to examine associations between staffing models with and without APPs and outcomes. MEASURES: The primary outcome was in-hospital mortality. Secondary outcomes included odds of hospital acquired conditions and ICU and hospital lengths of stay. RESULTS: The sample included 38,788 children in 40 PICUs. Patients admitted to PICUs with APP-inclusive staffing were younger (6.1±5.9 vs. 7.1±6.2 y) and more likely to have complex chronic conditions (64% vs. 43%) and organ failure on admission (25% vs. 22%), compared with patients in PICUs with physician-only staffing. There was no difference in mortality between PICU types [adjusted odds ratio (AOR): 1.23, 95% confidence interval (CI): 0.83-1.81, P=0.30]. Patients in PICUs with APP-inclusive staffing had lower odds of central line-associated blood stream infections (AOR: 0.76, 95% CI: 0.59-0.98, P=0.03) and catheter-associated urinary tract infections (AOR: 0.73, 95% CI: 0.61-0.86, P<0.001). There were no differences in lengths of stay. CONCLUSIONS: Despite being younger and sicker, children admitted to PICUs with APP-inclusive staffing had no increased odds of mortality and lower odds of some hospital acquired conditions compared with those in PICUs with physician-only staffing. Further research can inform APP integration strategies which optimize outcomes.

Psychiatric Medication Changes Associated With Increased Rate of Medical Readmissions in Patients With Serious Mental Illness.

ABSTRACT: To identify the impact of postdischarge psychiatric medication changes on general medical readmissions among patients with serious mental illness (SMI; bipolar disorder, major depressive disorder, and schizophrenia), claims from a 5% national sample of Medicare fee-for-service (FFS) beneficiaries hospitalized between 2013 and 2016 were studied. A total of 165,490 Medicare FFS beneficiaries with SMI 18 years or older with at least 1 year of continuous Medicare enrollment were identified. Within 30 days of discharge from index admission, 47.4% experienced a psychiatric medication change-including 75,892 beneficiaries experiencing a deletion and 55,713 experiencing an addition. After adjusting for potential confounders, those with a medication change experienced an 10% increase in the odds of 30-day readmission (odds ratio, 1.10; SE, 0.019; p < 0.001). Comorbid drug use disorder was also associated with an increased odds of readmission after controlling for other covariates. These findings suggest important factors that clinicians should be aware of when discharging patients with SMI.

Community socioeconomic disadvantage drives type of 30-day medical-surgical revisits among patients with serious mental illness.

BACKGROUND: Patients with serious mental illness (SMI) are vulnerable to medical-surgical readmissions and emergency department visits. METHODS: We studied 1,914,619 patients with SMI discharged after medical-surgical admissions in Florida and New York between 2012 and 2015 and their revisits to the hospital within 30 days of discharge. RESULTS: Patients with SMI from the most disadvantaged communities had greater adjusted 30-day revisit rates than patients from less disadvantaged communities. Among those that experienced a revisit, patients from the most disadvantaged communities had 7.3 % greater 30-day observation stay revisits. CONCLUSIONS: These results suggest that additional investments are needed to ensure that patients with SMI from the most disadvantaged communities are receiving appropriate post-discharge care.

Relationship between rural hospital closures and the supply of nurse practitioners and certified registered nurse anesthetists.

BACKGROUND: Reductions in primary care and specialist physicians follow rural hospital closures. As the supply of physicians declines, rural healthcare systems increasingly rely on nurse practitioners (NPs) and certified registered nurse anesthetists (CRNAs) to deliver care. PURPOSE: We sought to examine the extent to which rural hospital closures are associated with changes in the NP and CRNA workforce. METHOD: Using Area Health Resources Files (AHRF) data from 2010-2017, we used an event-study design to estimate the relationship between rural hospital closures and changes in the supply of NPs and CRNAs. FINDINGS: Among 1,544 rural counties, we observed 151 hospital closures. After controlling for local market characteristics, we did not find a significant relationship between hospital closure and the supply of NPs and CRNAs. DISCUSSION: We do not find evidence that NPs and CRNAs respond to rural hospital closures by leaving the healthcare market.

Practice environment, independence, and roles among DNP- and MSN-prepared primary care nurse practitioners.

BACKGROUND: Many nursing schools are adopting the Doctor of Nursing Practice (DNP) as the preferred model of nurse practitioner (NP) education and eliminating Master of Science in Nursing (MSN) programs. To date, no studies have explored the relationship between DNP preparation and NP practice environment, independence, and roles. PURPOSE: The purpos of this study is to compare practice environment, independence, and roles among DNP- and MSN-prepared primary care NPs. METHODS: This study used a cross-sectional design and observational regression analysis of survey data. FINDINGS: DNP-prepared NPs reported: 1) more favorable NP-Physician Relationships, 2) fewer clinical hours, and 3) more practice leadership. These differences were, however, small and not significant at 0.05 level. DISCUSSION: We found no major differences in practice environment, independence, and roles among DNP- and MSN-prepared primary care NPs. As more nursing schools establish DNP programs and more DNP-prepared NPs enter the field, it is especially important to continue to study the impact of DNP preparation on the NP workforce.
