The impact of nurse practitioner services on cost, quality of care, satisfaction and waiting times in the emergency department: A systematic review

AIMS To provide the best available evidence to determine the impact of nurse practitioner services on cost, quality of care, satisfaction and waiting times in the emergency department for adult patients. BACKGROUND The delivery of quality care in the emergency department is emerging as one of the most important service indicators in health delivery. Increasing service pressures in the emergency department have resulted in the adoption of service innovation models: the most common and rapidly expanding of these is emergency nurse practitioner services. The rapid uptake of emergency nurse practitioner service in Australia has outpaced the capacity to evaluate this service model in terms of outcomes related to safety and quality of patient care. Previous research is now outdated and not commensurate with the changing domain of delivering emergency care with nurse practitioner services. DATA SOURCES A comprehensive search of four electronic databases from 2006 to 2013 was conducted to identify research evaluating nurse practitioner service impact in the emergency department. English language articles were sought using MEDLINE, CINAHL, Embase and Cochrane and included two previous systematic reviews completed five and seven years ago. REVIEW METHODS A three step approach was used. Following a comprehensive search, two reviewers assessed all identified studies against the inclusion criteria. From the original 1013 studies, 14 papers were retained for critical appraisal on methodological quality by two independent reviewers and data were extracted using standardised tools. RESULTS Narrative synthesis was conducted to summarise and report the findings as insufficient data was available for meta-analysis of results. This systematic review has shown that emergency nurse practitioner service has a positive impact on quality of care, patient satisfaction and waiting times. There was insufficient evidence to draw conclusions regarding outcomes of a cost benefit analysis. CONCLUSION Synthesis of the available research attempts to provide an evidence base for emergency nurse practitioner service to guide healthcare leaders, policy makers and clinicians in reform of emergency service provision. The findings suggest that further high quality research is required for comparative measures of clinical and service effectiveness of emergency nurse practitioner service. In the context of increased health service demand and the need to provide timely and effective care to patients, such measures will assist in evidence based health service planning.

A Delphi study to validate an advanced practice nursing tool.

AIM This paper is a report of a study conducted to validate an instrument for measuring advanced practice nursing role delineation in an international contemporary health service context using the Delphi technique. BACKGROUND Although most countries now have clear definitions and competency standards for nurse practitioners, no such clarity exists for many advanced practice nurse roles, leaving healthcare providers uncertain whether their service needs can or should be met by an advanced practice nurse or a nurse practitioner. The validation of a tool depicting advanced practice nursing is essential for the appropriate deployment of advanced practice nurses. This paper is the second in a three-phase study to develop an operational framework for assigning advanced practice nursing roles. METHOD An expert panel was established to review the activities in the Strong Model of Advanced Practice Role Delineation tool. Using the Delphi technique, data were collected via an on-line survey through a series of iterative rounds in 2008. Feedback and statistical summaries of responses were distributed to the panel until the 75% consensus cut-off was obtained. RESULTS After three rounds and modification of five activities, consensus was obtained for validation of the content of this tool. CONCLUSION The Strong Model of Advanced Practice Role Delineation tool is valid for depicting the dimensions of practice of the advanced practice role in an international contemporary health service context thereby having the potential to optimize the utilization of the advanced practice nursing workforce.

Using the Donabedian framework to examine the quality and safety of nursing service innovation

AIMS AND OBJECTIVES To evaluate the safety and quality of nurse practitioner service using the audit framework of Structure, Process and Outcome. BACKGROUND Health service and workforce reform are on the agenda of governments and other service providers seeking to contain healthcare costs whilst providing safe and effective health care to communities. The nurse practitioner service is one health workforce innovation that has been adopted globally to improve timely access to clinical care, but there is scant literature reporting evaluation of the quality of this service innovation. DESIGN A mixed-methods design within the Donabedian evaluation framework was used. METHODS The Donabedian framework was used to evaluate the Structure, Process and Outcome of nurse practitioner service. A range of data collection approaches was used, including stakeholder survey (n = 36), in-depth interviews (11 patients and 13 nurse practitioners) and health records data on service processes. RESULTS The study identified that adequate and detailed preparation of Structure and Process is essential for the successful implementation of a service innovation. The multidisciplinary team was accepting of the addition of nurse practitioner service, and nurse practitioner clinical care was shown to be effective, satisfactory and safe from the perspective of the clinician stakeholders and patients. CONCLUSIONS This study demonstrated that the Donabedian framework of Structure, Process and Outcome evaluation is a valuable and validated approach to examine the safety and quality of a service innovation. Furthermore, in this study, specific Structure elements were shown to influence the quality of service processes further validating the framework and the interdependence of the Structure, Process and Outcome components. RELEVANCE TO CLINICAL PRACTICE Understanding the Structure and Process requirements for establishing nursing service innovation lays the foundation for safe, effective and patient-centred clinical care.

Neonatal palliative care attitude scale: development of an instrument to measure the barriers to and facilitators of palliative care in neonatal nursing.

OBJECTIVE. The aim of this research project was to obtain an understanding of the barriers to and facilitators of providing palliative care in neonatal nursing. This article reports the first phase of this research: to develop and administer an instrument to measure the attitudes of neonatal nurses to palliative care. METHODS. The instrument developed for this research (the Neonatal Palliative Care Attitude Scale) underwent face and content validity testing with an expert panel and was pilot tested to establish temporal stability. It was then administered to a population sample of 1285 neonatal nurses in Australian NICUs, with a response rate of 50% (N = 645). Exploratory factor-analysis techniques were conducted to identify scales and subscales of the instrument. RESULTS. Data-reduction techniques using principal components analysis were used. Using the criteria of eigenvalues being >1, the items in the Neonatal Palliative Care Attitude Scale extracted 6 factors, which accounted for 48.1% of the variance among the items. By further examining the questions within each factor and the Cronbachs α of items loading on each factor, factors were accepted or rejected. This resulted in acceptance of 3 factors indicating the barriers to and facilitators of palliative care practice. The constructs represented by these factors indicated barriers to and facilitators of palliative care practice relating to (1) the organization in which the nurse practices, (2) the available resources to support a palliative model of care, and (3) the technological imperatives and parental demands. CONCLUSIONS. The subscales identified by this analysis identified items that measured both barriers to and facilitators of palliative care practice in neonatal nursing. While establishing preliminary reliability of the instrument by using exploratory factor-analysis techniques, further testing of this instrument with different samples of neonatal nurses is necessary using a confirmatory factor-analysis approach.

Best practice in stabilisation of oral endotracheal tubes: A systematic review

Mechanical ventilation of patients in intensive care units is common practice. Artificial airways are utilised to facilitate ventilation and the endotracheal tube (ETT) is most commonly used for this purpose. The ETT must be stabilised to optimise ventilation and avoid displacement or unplanned extubation. Tube movement is a major factor in causing airway trauma. A destabilised tube can cause fatal complications. A systematic review was conducted to identify and analyse the best available evidence on ETT stabilisation to determine which stabilisation method resulted in reduced tube displacement and the least amount of unplanned or accidental extubations. The types of stabilisations included one or a combination of the following methods: twill or cotton tape, adhesive tape, gauze, or a manufactured device. All relevant randomised controlled and quasi-experimental studies of ETT stabilisation practices, identified through electronic and hand searching, were assessed for inclusion in the study. One published randomised controlled trial and six published quasi-experimental studies met the inclusion and exclusion criteria and were retrieved. Data were extracted independently by two reviewers. Results of the systematic review showed that no single method of ETT stabilisation could be identified as superior for minimising tube displacement and unplanned or accidental extubations. Rigorous randomised controlled trials with clearly identified and described ETT stabilisation methods are required to establish best practice. In addition, comparative research to evaluate cost effectiveness and nursing time requirements would also be of significant benefit to critical care nursing practice.

Measuring the effect of patient comfort rounds on practice environment and patient satisfaction: A pilot study

Hourly rounding in the acute hospital setting has been proposed as an intervention to increase patient satisfaction and safety, and improve the nursing practice environment, but the innovation has not been adequately tested. A quasi-experimental pretest post-test non-randomized parallel group trial design was used to test the effect of hourly patient comfort rounds on patient satisfaction and nursing perceptions of the practice environment, and to evaluate research processes and instruments for a proposed larger study. A Patient Satisfaction Survey instrument was developed and used in conjunction with the Practice Environment Scale of the Nursing Work Index. Results on patient satisfaction showed no significant changes. Significant changes were found for three of the five practice environment subscales. Consistent with the aim of a pilot study, this research has provided important information related to design, instruments and process that will inform a larger sufficiently powered study.

Reconceptualising the objectives of a pilot study for clinical research

This is a methodological study in which a case report is used to retrospectively analyse the link between a successful pilot study and stalled main study to identify potential methodological weaknesses in the planning process. The analysis identified unanticipated influences related to hospital processes and discipline boundaries that adversely influenced participant recruitment and retention for a clinical trial. The findings of the study demonstrate that, whilst the pilot is an important step in research planning to confirm the design and operational processes for a study, a thorough analysis of the relevant health service environment is an important additional objective for the pilot study.

Delineating the practice profile of advanced practice nursing: A cross-sectional survey using the modified strong model of advanced practice

AIMS To test a model that delineates advanced practice nursing from the practice profile of other nursing roles and titles. BACKGROUND There is extensive literature on advanced practice reporting the importance of this level of nursing to contemporary health service and patient outcomes. Literature also reports confusion and ambiguity associated with advanced practice nursing. Several countries have regulation and delineation for the nurse practitioner, but there is less clarity in definition and service focus of other advanced practice nursing roles. DESIGN A statewide survey. METHODS Using the modified Strong Model of Advanced Practice Role Delineation tool, a survey was conducted in 2009 with a random sample of registered nurses/midwives from government facilities in Queensland, Australia. Analysis of variance compared total and subscale scores across groups according to grade. Linear, stepwise multiple regression analysis examined factors influencing advanced practice nursing activities across all domains. RESULTS There were important differences according to grade in mean scores for total activities in all domains of advanced practice nursing. Nurses working in advanced practice roles (excluding nurse practitioners) performed more activities across most advanced practice domains. Regression analysis indicated that working in clinical advanced practice nursing roles with higher levels of education were strong predictors of advanced practice activities overall. CONCLUSION Essential and appropriate use of advanced practice nurses requires clarity in defining roles and practice levels. This research delineated nursing work according to grade and level of practice, further validating the tool for the Queensland context and providing operational information for assigning innovative nursing service.

Advanced practice nursing role development: factor analysis of a modified role delineation tool

AIM   This study reports the use of exploratory factor analysis to determine construct validity of a modified advanced practice role delineation tool. BACKGROUND   Little research exists on specific activities and domains of practice within advanced practice nursing roles, making it difficult to define service parameters of this level of nursing practice. A valid and reliable tool would assist those responsible for employing or deploying advanced practice nurses by identifying and defining their service profile. This is the third article from a multi-phase Australian study aimed at assigning advanced practice roles. METHODS   A postal survey was conducted of a random sample of state government employed Registered Nurses and midwives, across various levels and grades of practice in the state of Queensland, Australia, using the modified Advanced Practice Role Delineation tool. Exploratory factor analysis, using principal axis factoring was undertaken to examine factors in the modified tool. Cronbachs alpha coefficient determined reliability of the overall scale and identified factors. RESULTS   There were 658 responses (42% response rate). The five factors found with loadings of ≥400 for 40 of the 41 APN activities were similar to the five domains in the Strong model. Cronbachs alpha coefficient was 0·94 overall and for the factors ranged from 0·83 to 0·95. CONCLUSION   Exploratory factor analysis of the modified tool supports validity of the five domains of the original tool. Further investigation will identify use of the tool in a broader healthcare environment.

Understanding Cultural Competence in a Multicultural Nursing Workforce Registered Nurses’ Experience in Saudi Arabia

Purpose: In Saudi Arabia, the health system is mainly staffed by expatriate nurses from different cultural and linguistic backgrounds. Given the potential risks this situation poses for patient care, it is important to understand how cultural diversity can be effectively managed in this multicultural environment. The purpose of this study was to explore notions of cultural competence with non-Saudi Arabian nurses working in a major hospital in Saudi Arabia. Design: Face-to-face, audio-recorded, semistructured interviews were conducted with 24 non-Saudi Arabian nurses. Deductive data collection and analysis were undertaken drawing on Campinha-Bacote’s cultural competence model. The data that could not be explained by this model were coded and analyzed inductively. Findings: Nurses within this culturally diverse environment struggled with the notion of cultural competence in terms of each other’s cultural expectations and those of the dominant Saudi culture. Discussion: The study also addressed the limitations of Campinha-Bacote’s model, which did not account for all of the nurses’ experiences. Subsequent inductive analysis yielded important themes that more fully explained the nurses’ experiences in this environment. Implications for Practice: The findings can inform policy, professional education, and practice in the multicultural Saudi setting.
