RESUMEN
ABSTRACT: The vision of the American Academy of Nurse Practitioners Certification Board (AANPCB) is that nurse practitioners (NPs) meet the highest standards of excellence and competence to support quality care and optimal health outcomes. The highest standards of excellence require monitoring and improving our certification and recertification programs. After conducting a thorough review of the relevant literature and a series of surveys of our certificants, changes were made to the AANPCB recertification requirements that are consistent with continued competency. These changes are (1) maintaining a minimum of 1,000 advanced practice hours as an NP in the role of clinician, educator, administrator, and/or researcher plus obtaining 100 contact hours of qualified professional development credits; (2) allowing completion of the renewal criteria after the certification end date for individuals who have allowed their certification to expire; and (3) retiring the COVID temporary certification extension policy.

ABSTRACT: The nurse practitioner (NP) role within emergency care has grown in recent years and now there are an estimated 25,000 NPs employed in diverse emergency care settings. Despite this significant growth and expansion of the NP within emergency care areas, challenges exist. In addition to the pervasive confusion regarding the NP role in emergency care, data and statistics detailing characteristics and outcomes of NP practice in emergency care are either lacking or misrepresented. This article explores barriers and provides current and accurate information describing the current educational preparation, credentialing, scope of practice, and outcomes among NPs in US emergency departments. The totality of available evidence reviewed supports safe, timely, efficient, and patient-centered care provided by NPs in emergency care.

The role of the Emergency Nurse Practitioner (ENP) has evolved as a specialty and is appreciated within the context of the 2008 Consensus Model document (APRN Consensus Work Group & National Council of State Boards of Nursing APRN Advisory Committee, 2008). The first in a series of five articles, this article describes the appraisal of the ENP role as well as the specialty and the distinctive role of the ENP. The second article, Emergency Nurse Practitioner Practice Analysis: Report and Implications of the Findings, presents research to support the scientific basis of emergency specialty practice and content validity for a national certification program. Article 3, Beyond Competencies; Practice Standards for Emergency Nurse Practitioners: A Model for Clinicians, Educators, and Employers, introduces a new conceptual model that defines the specialty of emergency care's knowledge, skills, and abilities identified by the ENP practice analysis as practice standards not traditional competencies. In Article 4, Proposed Standardized Educational Preparation for the Emergency Nurse Practitioner, essential content for ENP preparation within graduate, postgraduate, and doctoral programs. The fifth article, Envisioning the Future for ENPs: Implications for Clinical Practice, Education, Research, and Health Policy, describes how ENPs are envisioning and impacting the future of emergency care and how their evolution can serve as a model for development of other advanced practice nursing specialties.

BACKGROUND AND PURPOSE: A practice analysis of nurse practitioners (NPs) working in emergency care was undertaken to define their job tasks and develop a specialty certification by examination. METHOD: In phase I, clinical experts created a qualitative description of domains of practice, tasks performed, knowledge required, and procedures performed by NPs in emergency care. Phase II involved validating the qualitative description through a national survey (N = 474) of emergency nurse practitioners (ENPs). Evidence from the validation survey was used to create a test content outline for the ENP examination. FINDINGS AND CONCLUSIONS: The delineation of ENP practice validated by the survey (Cronbach alpha = 0.86-0.94 across rating scales) included 5 ENP practice domains: medical screening, medical decision-making/differential diagnoses, patient management, patient disposition and professional, legal and ethical practices. There were 22 job tasks across domains, 10 types of patient conditions/emergency types, 42 knowledge areas, and 68 procedures performed by ENPs. These resulted in a test blueprint providing the foundation for the ENP certification examination content validity. IMPLICATIONS FOR PRACTICE: Beyond certification, the practice analysis has the potential to further inform the scientific basis of emergency specialty practice. Additional uses include refining professional scope and standards of practice, job descriptions, performance appraisals, research, and policy development.

BACKGROUND/PURPOSE: The growth of advanced practice nursing specialties requires additional expertise for practice that goes beyond entry-level competencies, knowledge, skills, and abilities. A practice standards model for specialty nurse practitioners (PSMSNPs) is introduced that differentiates entry-to-practice population foci competencies from advanced specialty practice standards. OBJECTIVES: (a) Differentiate competencies and practice standards in context to specialty NPs using the emergency specialty as the exemplar, (b) articulate the process to develop the PSMSNP that evolved from an evidence-based practice analysis of NPs working in emergency care, (c) apply the PSMSNP for adaptation to other specialties, and (d) provide implications for the utilization of the PSMSNP by educators, clinicians, and employers. DATA SOURCES: American Academy of Nurse Practitioners Certification Board's Practice Analysis of Emergency Nurse Practitioners, Consensus Model for APRN Regulation, Future of Nursing report, Peer Nursing Report, Strong Model of Advanced Practice, Entrustable Professional Activities, Emergency Medicine Milestones Project, and the Advancing Healthcare Transformation: A New Era for Academic Nursing report. CONCLUSIONS: The PSMSNP has been defined and adapted to other specialties and threaded through other models of practice for educators, clinicians, and employers. The adaptability of this model differentiates the core population foci and unique practice variables of specialty NPs. National boards of nursing, hospital credentialing committees, colleges, and universities can use this model to establish standards for specialty evaluation and guide clinical practice. IMPLICATIONS FOR PRACTICE: The implementation of the PSMSNP will support the delineation of the specialty. This model will fulfill the American Nurses Association and Consensus Model specialty constructs.

The dynamic climate within health care policy-making and academia, in conjunction with updated Emergency Nurse Practitioner (ENP) competencies and a recent role delineation study, supports development of standardized curricula to ensure appropriate preparation for practice. Emergency NP curricular content should align with the updated ENP Practice Standards and National Organization of Nurse Practitioner Faculties' competencies for the Core and Family NP. This article provides rationale for establishing standardized educational curricula for ENP programs, delineates core specialty curricular content for inclusion, and discusses applicability of ENP specialty competencies within graduate academic education and postgraduate fellowship programs. As national ENP program curricula are standardized, clarity of the ENP specialty role will be enhanced and educational outcomes can be uniformly evaluated.

The emergency nurse practitioner (ENP) specialty has grown rapidly, responding and adapting to changes within emergency care. Designation and advancement of nurse practitioner (NP) specialties follows a systematic process as defined by the profession. This includes establishment of scope and standards of practice, educational standards, and policy initiatives to ensure quality and safety within the profession. This article describes how the ENP specialty has used evidence to meet health system needs and chart a transformational future. Current recommendations for advancing health care transformation, as described by the American Association of Colleges of Nursing-Manatt Report, inform and frame the processes by which the ENP specialty has collaborated with diverse stakeholders to create a research and policy agenda to ensure that ENPs are appropriately prepared to lead and provide access to safe, affordable, quality health care. These processes provide a future-oriented model that promotes advancement of the NP profession through provision of new NP specialty designations as they emerge to meet changing health care system needs.

PURPOSE: The aim of two national studies was to identify characteristics of nurse practitioners (NPs) who precept and the benefits, incentives, and barriers associated with the NP preceptor role. METHODS: Stratified randomized sampling was used to invite a representative number of NPs from each state to participate in a 2015 survey and a follow-up survey in 2016. These descriptive, exploratory studies distributed electronic questionnaires to 5000 randomly selected NPs in the 2015 survey and 40,000 NPs in the 2016 survey. Responses from 10.9% (n = 548) and 9.9% (n = 3970), respectively, were analyzed. CONCLUSIONS: The findings show strong support among our NP colleagues to assist with educating future NPs. Several benefits, barriers, and motivators among stakeholders were identified that need to be considered when working with preceptors. IMPLICATIONS FOR PRACTICE: This study provides a basis for understanding the current climate in education when working with clinical preceptors. Many areas become apparent where NP education could enhance the experience for both the student and the preceptor. Educational settings need to consider preceptor time, issues with online learning, and the rise of specialty practices. Offering incentives linked to the most valued, positive aspects of the role and methods to overcome barriers should be explored.

PURPOSE: Examine the effects of a primary care weight management program, which used a parent-child-provider collaborative negotiation intervention, among rural-dwelling families with obese children. DATA SOURCES: Health histories, physical examinations, fasting blood samples, interviews, and questionnaires. CONCLUSIONS: Feasibility of implementing a family weight management intervention in a rural primary care setting was demonstrated. Few differences between the treatment and comparison groups were found; however, more favorable trends and outcomes occurred in those who received the intervention. IMPLICATIONS FOR PRACTICE: Positive provider-patient communication in helping families with obese children make difficult lifestyle changes should be encouraged in primary care clinics as small changes in behavior can result in reducing risk and improving health outcomes.

INTRODUCTION: Our aims were to assess postpartum health care barriers; health status (including depression and health behaviors); missed opportunities to discuss maternal health at health visits; acceptability of maternal screening in pediatric settings; and association of these variables with income level and race/ethnicity. METHOD: A mail survey was used with names randomly drawn from birth files and balanced for race/ethnicity and income level. RESULTS: The adjusted response rate was 27.6%, with 41% reporting one or more health care barrier(s), 22% screening positive for depression, and 30% screening positive for alcohol abuse. Women of lower income were eight times more likely than those of higher income to have health care barriers (adjusted odds ratio = 8.15; 95% confidence interval: 3.60, 18.44). Missed discussions of postpartum depression or behavioral health during pediatric or other health care visits ranged from 26% to 79%. Acceptability of discussing topics, including depression, smoking, and alcohol use at pediatric care visits generally exceeded 85%. DISCUSSION: Postpartum women experienced income-associated barriers to health care and generally had favorable views about maternal screening in pediatric settings.

As adolescents enter and exit high school, they face numerous changes that reflect the process of transitioning from childhood to adulthood. Concerns written by 216 adolescents who were part of a larger longitudinal study were analyzed for manifest content. Twenty-one categories of concerns were identified. The categories endorsed most frequently were education, relationships, expectations, and the future. Three of these differed significantly between the participant's first and fourth years in high school. These concerns reflect both developmental and situational transitions congruent with transition theory and have implications for nursing practice, research, and further theory development.

The Theory of Planned Behavior (TPB) served as a framework for analyzing focus group transcripts (N = 43) focused on parents' perceptions of the challenges of ensuring their children eat a healthy diet. The results suggest that parents consider their beliefs and behaviors as individuals within a society, within families, within cultures, as inheritors of family traditions, and as parents who influence or fail to influence the attitudes and behaviors of their children. The results showed the particular salience of factors related to the TPB concepts of perceived norms and control. Approaches to building theory-driven nursing interventions are suggested.

INTRODUCTION: Sevoflurane-remifentanil interaction models that predict responsiveness and response to painful stimuli have been evaluated in patients undergoing elective surgery. Preliminary evaluations of model predictions were found to be consistent with observations in patients anesthetized with sevoflurane, remifentanil, and fentanyl. This study explored the feasibility of adapting the predictions of sevoflurane-remifentanil interaction models to an isoflurane-fentanyl anesthetic. We hypothesized that model predictions adapted for isoflurane and fentanyl are consistent with observed patient responses and are similar to the predictions observed in our previous work with sevoflurane-remifentanil/fentanyl anesthetics. METHODS: Twenty-five patients scheduled for elective surgery received a fentanyl-isoflurane anesthetic. Model predictions of unresponsiveness were recorded at emergence, and predictions of a response to noxious stimulus were recorded when patients first required analgesics in the recovery room. Model predictions were compared with observations with graphical and temporal analyses. Results were also compared with our previous predictions after the administration of a sevoflurane-remifentanil/fentanyl anesthetic. RESULTS: Although patients were anesthetized, model predictions indicated a high likelihood that patients would be unresponsive (> or = 99%). After the termination of the anesthetic, model predictions of responsiveness well described the actual fraction of patients observed to be responsive during emergence. Half of the patients woke within 2 min of the 50% model-predicted probability of unresponsiveness; 70% woke within 4 min. Similarly, predictions of a response to a noxious stimulus were consistent with the number of patients who required fentanyl in the recovery room. Model predictions after the administration of an isoflurane-fentanyl anesthetic were similar to model predictions after a sevoflurane-remifentanil/fentanyl anesthetic. DISCUSSION: The results confirmed our study hypothesis; model predictions for unresponsiveness and no response to painful stimuli, adapted to isoflurane-fentanyl were consistent with observations. These results were similar to our previous study comparing model predictions and patient observations after a sevoflurane-remifentanil/fentanyl anesthetic.

INTRODUCTION: We previously reported models that characterized the synergistic interaction between remifentanil and sevoflurane in blunting responses to verbal and painful stimuli. This preliminary study evaluated the ability of these models to predict a return of responsiveness during emergence from anesthesia and a response to tibial pressure when patients required analgesics in the recovery room. We hypothesized that model predictions would be consistent with observed responses. We also hypothesized that under non-steady-state conditions, accounting for the lag time between sevoflurane effect-site concentration (Ce) and end-tidal (ET) concentration would improve predictions. METHODS: Twenty patients received a sevoflurane, remifentanil, and fentanyl anesthetic. Two model predictions of responsiveness were recorded at emergence: an ET-based and a Ce-based prediction. Similarly, 2 predictions of a response to noxious stimuli were recorded when patients first required analgesics in the recovery room. Model predictions were compared with observations with graphical and temporal analyses. RESULTS: While patients were anesthetized, model predictions indicated a high likelihood that patients would be unresponsive (> or = 99%). However, after termination of the anesthetic, models exhibited a wide range of predictions at emergence (1%-97%). Although wide, the Ce-based predictions of responsiveness were better distributed over a percentage ranking of observations than the ET-based predictions. For the ET-based model, 45% of the patients awoke within 2 min of the 50% model predicted probability of unresponsiveness and 65% awoke within 4 min. For the Ce-based model, 45% of the patients awoke within 1 min of the 50% model predicted probability of unresponsiveness and 85% awoke within 3.2 min. Predictions of a response to a painful stimulus in the recovery room were similar for the Ce- and ET-based models. DISCUSSION: Results confirmed, in part, our study hypothesis; accounting for the lag time between Ce and ET sevoflurane concentrations improved model predictions of responsiveness but had no effect on predicting a response to a noxious stimulus in the recovery room. These models may be useful in predicting events of clinical interest but large-scale evaluations with numerous patients are needed to better characterize model performance.

Child and adolescent obesity is a significant problem contributing to long-term trends in adult obesity. Educating parents about strategies for raising healthy children is complicated by the problem of low health literacy. E-health provides new opportunities to educate lowhealth-literate audiences, and this project was intended as formative research to guide design of interventions for low-health-literate parents. Focus groups were conducted with African American, Hispanic, and white parents (n = 43), 18 years of age or older, and at or below median income for the region. Each focus group included the following: a discussion of parents' general use of the Internet for health information, the demonstration of a Web site designed specifically for low-health-literate users, and asking participants about ideas under consideration for future interventions. Participants use search engines to look for health information and use heuristics, such as position in search results, to evaluate Web site quality. Some participants avoid information from .edu and .gov domains due to perceived complexity, and there was an almost-universal lack of trust in the government for health information. University researchers, by contrast, were trusted sources as information providers. Content and usability that meet the needs of extremely low-literate audiences may be perceived as slow and lacking depth by more literate and Internet-savvy users. E-health can be used to educate low-health-literate audiences, but interventions designed for these users must be layered in terms of content and usability to meet varying levels of functional and media literacy.

BACKGROUND: Part task training (PTT) focuses on dividing complex tasks into components followed by intensive concentrated training on individual components. Variable priority training (VPT) focuses on optimal distribution of attention when performing multiple tasks simultaneously with the goal of flexible allocation of attention. This study explored how principles of PTT and VPT adapted to anesthesia training would improve first-year anesthesiology residents' management of simulated adverse airway and respiratory events. The authors hypothesized that participants with PTT and VPT would perform better than those with standard training. METHODS: Twenty-two first-year anesthesia residents were randomly divided into two groups and trained over 12 months. The control group received standard didactic and simulation-based training. The experimental group received similar training but with emphasis on PTT and VPT techniques. Participant ability to manage seven adverse airway and respiratory events were assessed before and after the training period. Performance was measured by the number of correct tasks, making a correct diagnosis, assessment of perceived workload, and an assessment of scenario comprehension. RESULTS: Participants in both groups exhibited significant improvement in all metrics after a year of training. Participants in the experimental group were able to complete more tasks and answered more comprehension questions correctly. There was no difference in perceived workload or the number of correct diagnoses between groups. CONCLUSION: This study in part confirmed the study hypotheses. The results suggest that VPT and PTT are promising adjuncts to didactic and simulation-based training for management of adverse airway and respiratory events.

PURPOSE: To describe a parent-child-based model that melds a family-centered interaction approach, Touchpoints, with brief negotiation strategies (an adaptation of motivational interviewing) to address health risks in children. An application of the model for addressing childhood overweight in the primary care setting is presented. DATA SOURCES: Selected research, theoretical, and clinical articles; national recommendations and guidelines; and a clinical case. CONCLUSIONS: Lifestyle health behaviors are learned and reinforced within the family; thus, changes to promote child health require family involvement. Interventions that engage parents and support parent-child relationships, while enhancing motivation and the abilities to change behavior, are recommended. IMPLICATIONS FOR PRACTICE: Primary care is an appropriate setting for addressing lifestyle health behaviors. A collaborative partnership, rather than a prescriptive manner, is advocated for primary care providers when working to facilitate health-promoting behavior.

INTRODUCTION: In this study, we explored how a set of remifentanil-propofol response surface interaction models developed from data collected in volunteers would predict responses to events in patients undergoing elective surgery. Our hypotheses were that these models would predict a patient population's loss and return of responsiveness and the presence or absence of a response to laryngoscopy and the response to pain after surgery. METHODS: Twenty-one patients were enrolled. Anesthesia consisted of remifentanil and propofol infusions and fentanyl boluses. Loss and return of responsiveness, responses to laryngoscopy, and responses to postoperative pain were assessed in each patient. Model predictions were compared with observed responses. RESULTS: The loss of responsiveness model predicted that patients would become unresponsive 2.4 +/- 2.6 min earlier than observed. At the time of laryngoscopy, the laryngoscopy model predicted an 89% probability of no response to laryngoscopy and 81% did not respond. During emergence, the loss of responsiveness model predicted return of responsiveness 0.6 +/- 5.1 min before responsiveness was observed. The mean probability of no response to pressure algometry was 23% +/- 35% when patients required fentanyl for pain control. DISCUSSION: This preliminary assessment of a series of remifentanil-propofol interaction models demonstrated that these models predicted responses to selected pertinent events during elective surgery. However, significant model error was evident during rapid changes in predicted effect-site propofol-remifentanil concentration pairs.
