A National Study of Australian Nurse Practitioners’ Organizational Practice Environment

Better Nurse Practitioner Primary Care Practice Environments Reduce Hospitalization Disparities Among Dually-Enrolled Patients

BACKGROUND

Over 12 million Americans are dually enrolled in Medicare and Medicaid. These individuals experience over twice as many hospitalizations for chronic diseases such as coronary artery disease and diabetes compared with Medicare-only patients. Nurse practitioners (NPs) are well-positioned to address the care needs of dually-enrolled patients, yet NPs often work in unsupportive clinical practice environments. The purpose of this study was to examine the association between the NP primary care practice environment and hospitalization disparities between dually-enrolled and Medicare-only patients with chronic diseases.

METHODS

Using secondary cross-sectional data from the Nurse Practitioner Primary Care Organizational Climate Questionnaire and Medicare claims files, we examined 135,648 patients with coronary artery disease and/or diabetes (20.0% dually-eligible, 80.0% Medicare-only), cared for in 450 practices employing NPs across 4 states (PA, NJ, CA, FL) in 2015. We compared dually-enrolled patients' odds of being hospitalized when cared for in practice environments characterized as poor, mixed, and good based on practice-level Nurse Practitioner Primary Care Organizational Climate Questionnaire scores.

RESULTS

After adjusting for patient and practice characteristics, dually-enrolled patients in poor practice environments had the highest odds of being hospitalized compared with their Medicare-only counterparts [odds ratio (OR): 1.48, CI: 1.37, 1.60]. In mixed environments, dually-enrolled patients had 27% higher odds of a hospitalization (OR: 1.27, CI: 1.12, 1.45). However, in the best practice environments, hospitalization differences were nonsignificant (OR: 1.02, CI: 0.85, 1.23).

CONCLUSIONS

As policymakers look to improve outcomes for dually-enrolled patients, addressing a modifiable aspect of care delivery in NPs' clinical practice environment is a key opportunity to reduce hospitalization disparities.

The Multilevel Reliability and Interrater Agreement of the Nurse Practitioner Primary Care Organizational Climate Questionnaire

Background and Purpose: It is critical to accurately measure and understand the nurse practitioner (NP) work environment in which individual NP information is gathered but decisions or inferences are made at an aggregated, group level. However, there is little research on preconditions of aggregating individual-level data into group level in nursing research. This study was conducted to assess the multilevel reliability and group interrater agreement (IRA) of the Nurse Practitioner Primary Care Organizational Climate Questionnaire. Methods: Secondary data analysis from a cross-sectional survey with 247 NPs in 112 practices across 6 U.S. states in 2018-2019 was used. Results: The generalizability coefficients and values of IRA were acceptable (> .70), and values of ICC(1) were significant (.18-.38). Conclusions: Aggregating individual NP data to a higher group-level work environment construct is acceptable.

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.

A qualitative study exploring nursing home care environments where nurse practitioners work

Research is needed to support the growing nurse practitioner workforce to assure higher quality care for older adults in nursing homes. Nursing homes with optimal care environments that support nurse practitioner roles, increased visibility, independence, and relationships are better positioned to support care of older adults. This study reports findings of thirteen qualitative interviews with nurse practitioners to explore facets of nursing home care environments and adapt a tool to measure care environments. Our team incorporated deductive and inductive coding to identify three major emerging themes impacting care environments: 1) nurse practitioner practice in nursing homes, 2) overall goals of practice, 3) workplace challenges. Themes were derived from seven overarching categories and 33 codes describing aspects of NH care environment important to nurse practitioners. Some of the most highly important survey items measured nurse practitioner and physician relationships. Less important items measured relationships between nurse practitioners and administration.

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.

Constructing the advanced nurse practitioner identity in the healthcare system: A discourse analysis

AIMS

To explore how Advanced Nurse Practitioners (ANP) are positioned within current nursing and health system structures in Ireland by making explicit the discourses that construct ANPs' identities and how they both enable and constrain their roles.

BACKGROUND

Ambiguity and confusion characterize debates about the ANP role having a profound impact on ANP identity and how they realize their roles. Without clear definitions, boundaries are difficult to ascertain, the full potential of the ANP is not realized and, consequently, ANPs are underutilized. Although this study is relevant outside Ireland's borders, it is of particular concern in the Irish setting as current policy aims to increase ANP numbers.

DESIGN

A qualitative discourse analysis using Gee's Tools of Inquiry.

METHOD

Data were collected between April 2019 and January 2020 through seven in-depth interviews and four focus groups and analysed using Gee's Tools of Inquiry. Participants included ANPs, nurses, doctors and allied healthcare professionals.

FINDINGS

Five key discourses emerged. Language-in-use established, first, that ANPs add value to the healthcare system and, second, highlighted the centrality of nursing to ANPs' identity. The third discourse builds an educated and skilled identity for ANPs, one that, however, lacked the expertise and influence of their medical colleagues. The fourth discourse constructs an identity for ANPs as medical substitutes, lesser roles, yet innovative additions to the system and a threat to existing structures. The final discourse constructs tensions between independence and autonomy, on the one hand, and control, on the other.

CONCLUSION

This study alerts healthcare professionals to ways in which discourses influence opinion and frame ANPs' identity. Healthcare professionals should challenge Conversations and Discourses that disparage the ANP role. ANPs need to clearly articulate their role, the value that it adds to the healthcare system and demonstrate how it aligns with and complements other healthcare professionals' roles.

IMPACT

By identifying and critiquing extant Discourses and Conversations, healthcare professionals, and health system leaders and managers will gain a better understanding of the issues that both enable and constrain the ANP role.

Employing nurse practitioners in general practice: an exploratory survey of the perspectives of managers

INTRODUCTION Establishing the nurse practitioner (NP) workforce in New Zealand is a viable solution to health and workforce challenges in primary health care. General practices have been slow to implement NP services. Managers of general practices are central to the employment and development of NP roles. AIM To explore the perspectives of managers on employing NPs in general practice. METHODS An electronic survey was used to collect demographic and numerical data, which were analysed descriptively and analytically using SPSS (version 26). Written answers to open-ended questions were analysed qualitatively. RESULTS In total, 143 managers participated in the survey (response rate 39.7%); 54 (37.8%) worked in practices employing at least one NP. Of respondents, 88.9% (n = 127) agreed or strongly agreed that NPs could enhance continuity of care (89/143, 62.2%), improved access to services and medications (89/143, 62.2%) and filled a gap that added value to health care (97/143, 67.8%). Practices employing NPs had statistically significant higher levels of agreement about the advantages of NPs than practices not employing NPs. Challenges and enablers to employing NPs were themed under organisational environment, NP scope of practice and role, and NP workforce development. DISCUSSION This exploratory study revealed that there is little knowledge about the NP workforce in surveyed general practices. Ongoing work is required to improve knowledge for employing general practices, including dissemination of information about NP education and training, scope and models of care, and ability to generate business income.

Nurse practitioner work patterns: A cross-sectional study

AIM

The aim was to determine how nurse practitioner (NP) roles are translated into clinical practice across Victoria, Australia. This paper reports details about NP work patterns and scopes of practice across multiple clinical settings and geographic locations.

DESIGN

A quantitative survey design was used. A data abstraction tool, based on previous work, was adapted for this study.

METHODS

All NPs in one state of Australia were eligible to participate in the study and invited to complete an online survey about their NP practice. A previously developed data collection tool, capturing practice patterns of NPs, was adapted for online use in REDCAP. The data were exported, and descriptive statistics were analysed using SPSS.

RESULTS

Participants were mostly female, with males accounting for 25%. Findings indicate several NPs working in outpatient settings, community settings and forensic care. Patterns of practice-prescribing and ordering diagnostics-are associated with clinical context and model of care of the NP work.

Nurse practitioner locums: a plausible solution for augmenting health care access for rural communities

With 2020 being designated the Year of the Nurse and Midwife, it is opportune to acknowledge and recognise the role that nurses undertake in primary care environments. Nurses and midwives play a pivotal role in the delivery of high-quality health care, particularly in geographically challenged areas of Australia, where they may be the only provider of care within their communities. Rural and remote health services require strategic planning to develop and implement solutions responsive to the challenges of rural and remote communities. Maintenance of health services in rural and remote areas is a challenge, crucial to the equity of health outcomes for these communities. Many small communities rely on visiting medical officers to provide the on-call care to facility services, including emergency departments, urgent care centres, acute wards and aged care facilities. It is increasingly difficult to maintain the current rural workforce models, particularly the provision of after-hours 'on-call' care necessary in these communities. An alternative model of health care service delivery staffed by nurse practitioners (NP) is one proposed solution. NPs are educated, skilled and proven in their ability to provide an after-hours or on-call service to meet the expectations of rural and remote communities. Achievement of high-quality health care that is cost-efficient, safe and demonstrates improved patient outcomes has been reported in NP-led health care delivery impact evaluations. The value of an NP locum service model is the provision of a transparent, reliable service delivering consistent, equitable and efficient health care to rural and remote communities.

Relationship between nurse practice environment and work outcomes: A survey study in the Philippines

AIMS

Challenges in the nurse practice environment greatly affect nurse work outcomes. This study investigated the relationship between nurse practice environment and work outcomes in the Philippines.

METHODS

This cross-sectional survey involved 549 hospital nurses in the Philippines in 2018. The nurse practice environment was measured using the Practice Environment Scale of the Nursing Work Index (PES-NWI). Four self-report scales were used to measure work outcomes: job satisfaction, job burnout, job stress and nurse-assessed quality of care. Multiple linear regression analysis was used to analyse the data.

RESULTS

Significant relationships were found between nurse and organizational characteristics and nurse practice environment. Further, multivariate regression analysis revealed that the nurse practice environment had a significant and positive relationship with perceived quality of care and a significant and negative relationship with job burnout and job stress.

CONCLUSION

A favourable work environment significantly reduced job burnout and job stress and improved the quality of patient care. With considerable migration abroad, a favourable nurse practice environment may engage a better nurse workforce in the country and subsequently reduce migration. Managers must focus on developing good nurse practice environments that will improve professional work outcomes and quality patient care.

Nurse practitioner primary care organizational climate questionnaire: Item response theory and differential item functioning

AIMS AND OBJECTIVES

To validate Nurse Practitioner Primary Care Organizational Climate Questionnaire (NP-PCOCQ) items using item response theory (IRT) models and conduct differential item functioning (DIF) analysis to test the item functioning among nurse practitioners (NPs) practicing in different U.S. states with variable regulations governing NP practice.

BACKGROUND

Nurse Practitioner Primary Care Organizational Climate Questionnaire is the only NP-specific tool measuring NP work environment and is being used in different U.S. states with variable NP scope of practice regulations and internationally to produce evidence about NP work environments within their organisations.

DESIGN

Cross-sectional survey design was used to collect data from 278 primary care NPs in New York (NY) and 314 NPs in Massachusetts (MA).

METHODS

NPs completed the 29-item NP-PCOCQ. Data collection involved an online survey in NY and a mail survey in MA in 2012. We used Samejima's graded response model for IRT and ordinal logistic regression for DIF analysis. A STROBE checklist was completed.

RESULTS

IRT models yielded discrimination parameters ranging from 0.98-4.65 in NY and 1.25-6.94 in MA. Item difficulty parameters were within -3 to +3 range, suggesting a fair range of item difficulties exist in the scale. Only five of the 29 items on NP-PCOCQ exhibited DIF, suggesting some other state-related factor besides the measured construct influenced item responses; thus, the items were removed.

CONCLUSION

Our findings indicate that a shortened, 24-item NP-PCOCQ is capable of measuring organisational climate of NPs practicing in different U.S. states. NP-PCOCQ can be used in future research to measure NP work environment.

RELEVANCE TO CLINICAL PRACTICE

The tool can also be used by practice administrators to assess NP work environment and identify deficiencies to address them. This evidence about NP work environment can be used by practice administrators to promote favourable work environments for NPs to deliver high-quality care.
