Analysis of education and previous nursing experience of certified PNPs in the United States.

BACKGROUND: Educational programs to prepare nurse practitioners (NPs) were historically built upon foundational nursing experience. Originally prepared as certificate programs in 1965, the educational requirements for nurse practitioners (NPs) rapidly shifted from certificate programs to the Master's degree (DellaBella, 2015; Fairman, 2008). As Doctor of Nursing Practice (DNP) degree programs increase in number, it is unknown whether this foundational nursing experience has changed, or if it differs by certification type for pediatric nurse practitioners (PNPs). This study aimed to evaluate the educational preparation and prior nursing experience of primary care and acute care certified PNPs. METHODS: A national survey of members of the Pediatric Nurse Practitioner Certification Board (N = 17,530) was completed (Mudd et al., 2022). A sub-analysis of this data was conducted (n = 1974). RESULTS: There was no statistical evidence among either primary or acute care PNPs of an association between previous nursing experience and type of degree preparation (Master's or DNP). There was only a weak association between educational preparation and experience among acute care nurse practitioners. Most respondents were prepared at the Master's level, and 85% of all respondents had >1 year of nursing experience prior to returning for additional PNP education. DISCUSSION: This study adds to the literature as it describes the educational preparation and foundational nursing experience of primary and acute care PNPs. It can serve as a benchmark as the move to the DNP continues for Advanced Practice Registered Nurse preparation.

Development and Validation of a Point-of-Care-Ultrasound Image Quality Assessment Tool: The POCUS IQ Scale.

OBJECTIVES: We aimed to develop a standardized scoring tool to measure point-of-care ultrasound (POCUS) image quality and to determine validity evidence for its use to assess lung ultrasound image quality. METHODS: The POCUS Image Quality (POCUS IQ) scale was developed by POCUS-trained physicians to assess sonographers' image acquisition skills by evaluating image quality for any POCUS application. The scale was piloted using lung images of healthy standardized patients acquired by three expert sonographers compared to three novices before and after training. All images (experts, novices pre-training, novices post-training) were scored on the POCUS IQ scale by three blinded POCUS-trained physicians. Reliability was assessed with fully-crossed generalizability and decision studies. Validity was assessed using Messick's framework. RESULTS: Content validity was supported by the tool's development process of literature review, expert consensus, and pilot testing. Response process was supported by reviewer training and the blinded scoring process. Relation to other variables was supported by scores relating to sonographer experience: median expert score = 10.5/14 (IQR: 4), median novice pre-training score = 6/14 (IQR: 2.25), and novices' improvement after training (median post-training score = 12/14, IQR: 3.25). Internal structure was supported by internal consistency data (coefficient alpha = 0.84, omega coefficient = 0.91) and the generalizability study showing the main contributor to score variability was the sonographer (51%). The G-coefficient was 0.89, suggesting very good internal structure, however, Gwet's AC2  was 0.5, indicating moderate interrater reliability. The D study projected a minimum of 1 reviewer and 2 patients are needed for good psychometric reliability. CONCLUSIONS: The POCUS scale has good preliminary validity evidence as an assessment tool for lung POCUS image acquisition skills. Further studies are needed to demonstrate its utility for other POCUS applications and as a feedback tool for POCUS learners.

Exploring Health Care Disparities in Maternal-Child Simulation-Based Education.

AIM: The purpose of this study was to explore student experiences within a health care disparity simulation, embedded in maternal-child content. BACKGROUND: Health care disparities related to race and ethnicity in the maternal-child population are daunting among African American and Hispanic women. METHOD: Participants completed the Simulation Effectiveness Tool-Modified, a rapid-fire huddle questionnaire, and a demographic instrument. All students participated in structured debriefing. RESULTS: Student responses ( n = 69) demonstrated effectiveness in learning via this scenario. CONCLUSION: The rapid-fire huddle and debriefing are important elements when health care disparities are introduced into nursing curricula.

Evaluating validity evidence for 2 instruments developed to assess students' surgical skills in a simulated environment.

OBJECTIVE: To gather and evaluate validity evidence in the form of content and reliability of scores produced by 2 surgical skills assessment instruments, 1) a checklist, and 2) a modified form of the Objective Structured Assessment of Technical Skills (OSATS) global rating scale (GRS). STUDY DESIGN: Prospective randomized blinded study. SAMPLE POPULATION: Veterinary surgical skills educators (n =10) evaluated content validity. Scores from students in their third preclinical year of veterinary school (n = 16) were used to assess reliability. METHODS: Content validity was assessed using Lawshe's method to calculate the Content Validity Index (CVI) for the checklist and modified OSATS GRS. The importance and relevance of each item was determined in relation to skills needed to successfully perform supervised surgical procedures. The reliability of scores produced by both instruments was determined using generalizability (G) theory. RESULTS: Based on the results of the content validation, 39 of 40 checklist items were included. The 39-item checklist CVI was 0.81. One of the 6 OSATS GRS items was included. The 1-item GRS CVI was 0.80. The G-coefficients for the 40-item checklist and 6-item GRS were 0.85 and 0.79, respectively. CONCLUSION: Content validity was very good for the 39-item checklist and good for the 1-item OSATS GRS. The reliability of scores from both instruments was acceptable for a moderate stakes examination. IMPACT: These results provide evidence to support the use of the checklist described and a modified 1-item OSAT GRS in moderate stakes examinations when evaluating preclinical third-year veterinary students' technical surgical skills on low-fidelity models.

The Scope of Hospital-Based Simulation.

BACKGROUND: Healthcare simulation has expanded dramatically; however, little is known about the scope of simulation in acute care hospitals. METHODS: A descriptive, cross-sectional online survey was used. Participants included nurse executives from acute care hospitals in California. RESULTS: Most organizations (96%) used simulation primarily for education, 37% used simulation for health system integration and systems testing, 30% used it for error investigation, 15% used it for research, and 15% used it for patient/family education. CONCLUSIONS: Organizations have a substantial opportunity to increase the scope of simulation beyond education to include systems integration, clinical systems testing, and other translational simulation activities. This targeted focus on patient safety and quality will allow hospitals to improve financial performance and maximize scarce resources.

Implementing a Clinical Practice Guideline on Opioid-Induced Advancing Sedation and Respiratory Depression.

BACKGROUND: Opioid-induced respiratory depression (OIRD) is a serious adverse reaction associated with opioid administration. LOCAL PROBLEM: The purpose of this quality improvement study was to evaluate the impact of implementing a clinical practice guideline for OIRD in a medical-surgical setting lacking standardized monitoring techniques and reporting criteria for patients receiving opioid analgesia. METHODS: An American Society for Pain Management Nursing protocol was implemented in 4 medical/surgical units. The impact on OIRD-related nurse knowledge, documentation, and opioid-related rapid response calls was measured pre- and postimplementation. RESULTS: Nurse OIRD-related knowledge significantly increased. The number of naloxone administrations associated with prior intravenous opioid analgesic administration did not significantly change. However, there was a significant decrease in the postimplementation number of respiratory distress-related rapid response calls. CONCLUSIONS: Implementation of the American Society for Pain Management Nursing guidelines had a positive impact on knowledge, documentation, early intervention of OIRD, and the number of opioid-related rapid response calls.

Exploring the development of professional values in an online RN-to-BSN program.

BACKGROUND: Development of professional nursing values is critical within registered nurse-to-bachelor of science in nursing programs to prepare nurses for increasingly complex and diverse work environments. The results of previous studies have been inconsistent, with few studies focusing on online registered nurse-to-bachelor of science in nursing programs. In addition, little is known regarding the effectiveness of the educational methods used to support advancement of professional values and ethical practice. OBJECTIVE: The object of this study was to gain an understanding of nursing students' attitudes and beliefs about professional values at entry and exit of an online registered nurse-to-bachelor of science in nursing program that includes a standalone ethics course and integrates American Nurses Association Code of Ethics provisions throughout the curriculum. RESEARCH DESIGN: For this one-group pretest-posttest, quasi-experimental design, longitudinal matched-pair data were gathered at program entry and exit using the Nurses Professional Values Scale-Revised. PARTICIPANTS AND RESEARCH CONTEXT: In all, 119 students of an online registered nurse-to-bachelor of science in nursing program at a Midwest public university who completed entry and exit surveys between spring 2015 and spring 2018 were included in this study. ETHICAL CONSIDERATIONS: This study was reviewed and determined to be exempt by the university's institutional review board. FINDINGS: The results showed a significant increase in total posttest scores when considering all participants. However, students who took the ethics course after the pretest demonstrated a significant increase in posttest scores, while students who took the ethics course prior to the pretest demonstrated a small increase that was not statistically significant. Significant increases were also found in the professionalism, activism, and trust factors. DISCUSSION: This study supports previous study findings where students scored higher on caring and lower on activism and professionalism factors. The largest gains were made after completing the ethics course. CONCLUSION: The results suggest that requiring a standalone ethics course in the registered nurse-to-bachelor of science in nursing curriculum had a positive impact on self-reported professional values.

Using online game-based platforms to improve student performance and engagement in histology teaching.

BACKGROUND: Human morphology is a critical component of dental and medical graduate training. Innovations in basic science teaching methods are needed to keep up with an ever-changing landscape of technology. The purpose of this study was to investigate whether students in a medical and dental histology course would have better grades if they used gaming software Kahoot® and whether gamification effects on learning and enjoyment. METHODS: In an effort to both evoke students' interest and expand their skill retention, an online competition using Kahoot® was implemented for first-year students in 2018 (n = 215) at the University of Eastern Finland. Additionally, closed (160/215) or open-ended (41/215) feedback questions were collected and analyzed. RESULTS: The Kahoot® gamification program was successful and resulted in learning gains. The overall participant satisfaction using Kahoot® was high, with students (124/160) indicating that gamification increased their motivation to learn. The gaming approach seemed to enable the students to overcome individual difficulties (139/160) and to set up collaboration (107/160); furthermore, gamification promoted interest (109/160), and the respondents found the immediate feedback from senior professionals to be positive (146/160). In the open-ended survey, the students (23/41) viewed collaborative team- and gamification-based learning positively. CONCLUSION: This study lends support to the use of gamification in the teaching of histology and may provide a foundation for designing a gamification-integrated curriculum across healthcare disciplines.

Development and Psychometric Evaluation of the Facilitator Competency Rubric.

AIM: The purpose of the study was to evaluate the psychometric properties of the Facilitator Competency Rubric (FCR). BACKGROUND: The FCR was developed to fill a deficit in tools available to holistically evaluate competency of simulation facilitators. METHOD: The FCR has five constructs: preparation, prebriefing, facilitation, debriefing, and evaluation. Benner's novice-to-expert theory was used to categorize subcomponents. Expert panel validation was sought. Participants from four baccalaureate nursing programs completed 107 observations of facilitators using the FCR. RESULTS: Interrater reliability as assessed using generalizability theory was good. G coefficients ranged from good to excellent (.80 to .99). FCR items appeared to be well constructed. Term, day of the week, time of day, and simulation type were significant predictors of the FCR global score. CONCLUSION: The FCR is a valid, reliable tool that can be used for formative or summative evaluation of simulation facilitators. Scores can guide and prioritize faculty development.

Bovine Reproductive Palpation Training: Does the Cow Make a Difference?

Gaining experience and dexterity for trans-rectal cattle palpation requires substantial training. Simulation allows students to perform palpation without risks and to obtain feedback, but many believe live cattle palpation is essential. Limited research exists on the proper training method for live animal trans-rectal palpation. This study compared student improvement in laboratory palpation skills when assigned to the same cows versus choosing a cow at random. The hypothesis for the study was that students assigned the same cow, as compared to students choosing a cow at random, would be more accurate at palpation, would learn what structures are present on the ovaries and what size the reproductive tract measures, and would be able to follow the cyclicity of the cow. Cervical diameter, uterine tone, diameter of left and right uterine horns, and ovarian structures were recorded over time. Responses were compared to laboratory instructors' responses and Z-tests for proportions were used to test the differences in percentage correct at each time point for each palpation exercise. Overall the experiment showed that assigning students to certain cows will not improve their trans-rectal palpation training. However, asking students to identify specific landmarks with quantitative measurements did allow for more productive laboratory time and engaged students. The results of the present study also suggest that if there is limited time available for palpation instruction, choosing cows with behavior allowing easy handling is important to the educational process.

Development and Student Evaluation of an Anatomically Correct High-Fidelity Calf Leg Model.

Obstetrical chain placement requires location of specific landmarks and a certain dexterity that must be practiced. Use of low-fidelity models may not always provide students with a realistic experience. In this study we developed an anatomically correct high-fidelity calf leg model that would serve as a better teaching model for pre-clinical veterinary students than a pre-existing low-fidelity polyvinyl chloride (PVC) model. One hundred and twenty pre-clinical veterinary students were instructed how to use obstetrical chains with a low-fidelity PVC model and the anatomically correct high-fidelity calf leg model. After a 45-minute lab, students were surveyed on their experience with both models. Overall students felt the anatomically correct high-fidelity calf leg model increased accuracy in chain placement and provided more accurate landmarks, a more realistic model, and more real-life scenario training.

Differential impact of longitudinal medication non-adherence on mortality by race/ethnicity among veterans with diabetes.

OBJECTIVE: To examine the differential effect of medication non-adherence over time on all-cause mortality by race/ethnicity. RESEARCH DESIGN AND METHODS: Data on a longitudinal cohort of veterans with type 2 diabetes was examined. The main outcome was time to death. Primary independent variables were race/ethnicity and mean medication possession ratio (MPR) categorized into quintiles over the study period. Cox regression was used to model the association between time to death and MPR quintiles and race/ethnicity, adjusting for relevant covariates. RESULTS: The cohort of 629,563 veterans was followed for 5 years. After adjusting for all covariates, the hazard ratios (HR) for subjects in the lowest versus highest MPR quintile was 12.21 (95 % CI 11.89, 12.55) for non-Hispanic white (NHW), 10.01 (95 % CI 9.18, 10.91) for non-Hispanic black (NHB), 12.65 (95 % CI 11.10, 14.43) for Hispanic and 10.41 (95 % CI 9.06, 11.96) for Other race veterans. Furthermore, type of diabetes therapy (oral versus insulin) maintained a significant relationship with mortality that varied by racial/ethnic group. CONCLUSIONS: This study demonstrates the differential impact of medication non-adherence on mortality by race. It also demonstrates that type of diabetes therapy (insulin with or without oral agents) is associated with mortality and varies by racial/ethnic group.

Factors associated with delays in seeking treatment for stroke care in veterans.

BACKGROUND: Our objective was to examine the association between delay in seeking treatment (DST) for stroke care and demographic and clinical characteristics variables in a sample of veterans. METHODS: We used survey data from 100 veterans with a diagnosis of stroke who were receiving poststroke care at a Veterans Affairs (VA) Medical Center in the southeastern United States to evaluate the relationship between DST and key sample demographic and clinical characteristics. We used backward stepwise logistic regression models to assess the independent association between DST and demographic and clinical variables. RESULTS: We found that stroke survivors reporting DST were more likely to be black (56.4% versus 32.8%; P = .02) and younger at the time of stroke onset (58.1 years versus 63.7 years; P = .02). In backward stepwise logistic regression models, being black was an independent predictor of DST (odds ratio [OR] 2.76; 95% confidence interval [CI], 1.04-7.30; P = .04) in this veteran population. CONCLUSIONS: Race appears to be a key factor associated with an increased likelihood of delays in seeking urgent stroke care in veterans. Future studies need to further examine the complex sociodemographic profile of patients who are most likely to delay seeking care for stroke and to develop interventions to reduce the impact of DST.

A retrospective study of subcutaneous anchor securement systems in oncology patients.

INTRODUCTION: Maintaining optimal central venous catheter tip position requires reliable catheter securement. A vital decision about the choice of engineered securement device is often made by what is conveniently available in the insertion kit or default clinical routine. The importance of continuous securement for oncology patients prompted the need for an evaluation of securement options currently available. This study aimed to assess the effectiveness of two engineered securement devices to assist the oncology patient in reaching the end of their catheter need. METHODS: A retrospective study was conducted to assess patients' ability to finish their therapy with one peripherally inserted central catheter. Implant and explant data for adult oncology patients was evaluated spanning 2007-2021. All patients received a PICC with either an adhesive securement device or a subcutaneous anchor securement system. RESULTS: Partial or complete dislodgement causing the unplanned removal of the PICC occurred at 12% for ASD and 0.4% for SASS (p < 0.0001). The probability of reaching the end of need with one PICC, regardless of the reason for premature removal, at 2 years for patients with an adhesive securement device was 68% (n = 944). For patients with a subcutaneous anchored securement device, it was over 95% (n = 8313). The difference in the probability of reaching the end of the need with one PICC between the two securement devices was calculated at (p < 0.0001). CONCLUSION: With over 9200 patients and more than a million catheter days, the results of this retrospective study demonstrate the SASS's superiority in assisting the patient to reach the end of need with a single PICC.

Curricular Integration of Virtual Reality in Nursing Education.

AIM: The purpose of this article was to evaluate the ability of an interactive virtual reality (VR) platform guided by standards of best practice to provide an effective immersive learning environment. We specifically evaluated usability of the platform and learners' perceptions of the experience. BACKGROUND: A variety of strategies are needed to train a highly competent nursing workforce. METHODS: We conducted a quantitative cross-sectional study to evaluate the VR experience using the System Usability Scale (SUS)® and the Simulation Effectiveness Tool-Modified (SET-M). RESULTS: Post-simulation evaluations were completed by 127 prelicensure and 28 advanced practice students. On the SUS scale, students found the overall VR system easy to navigate, and on the SET-M, they rated the VR experience positively. CONCLUSION: Immersive technology such as VR with a defined curriculum and facilitated debriefing can be valuable for student learning and may ultimately effect patient care.

Evaluating the Practice of Pediatric Nurse Practitioners: Is It Time for Dual Primary and Acute Care Preparation?

This survey aimed to evaluate contemporary pediatric nurse practitioner (PNP) practice as it relates to the competencies of both the primary and acute care population focus and settings of practice to guide curriculum revisions. The design of the study was a cross-sectional survey of PNPs certified by the Pediatric Nursing Certification Board. There were 2,265 surveys completed. Regardless of the certification type, PNPs report providing care across settings and integrating the competencies of both the primary and acute care PNP into practice. This warrants further consideration by programs to prepare future PNPs for dual primary and acute care certification.

The Concise Assessment of Leader Management Tool: Evaluation of Healthcare Provider Leadership During Real-Life Pediatric Emergencies.

INTRODUCTION: Resuscitation events in pediatric critical and emergency care are high risk, and strong leadership is an important component of an effective response. The Concise Assessment of Leadership Management (CALM) tool, designed to assess the strength of leadership skills during pediatric crises, has shown promising validity and reliability in simulated settings. The objective of this study was to generate further validity and reliability evidence for the CALM by applying it to real-life emergency events. METHODS: A prospective, video-based study was conducted in an academic pediatric emergency department. Three reviewers independently applied the CALM tool to the assessment of pediatric emergency department physicians as they led both a cardiac arrest and a sepsis event. Time to critical event (epinephrine, fluid, and antibiotic administration) was collected via video review. Based on Kane's framework, we conducted fully crossed, person × event × rater generalizability (G) and decision (D) studies. Interrater reliability was calculated using Gwet AC 2 and intraclass correlation coefficients. Time to critical events was correlated with CALM scores using Spearman coefficient. RESULTS: Nine team leaders were assessed in their leadership of 2 resuscitations each. The G coefficient was 0.68, with 26% subject variance, 20% rater variance, and no case variance. Thirty-three percent of the variance (33%) was attributed to third-order interactions and unknown factors. Gwet AC 2 was 0.3 and intraclass correlation was 0.58. The CALM score and time to epinephrine correlated at -0.79 ( P = 0.01). The CALM score and time to fluid administration correlated at -0.181 ( P = 0.64). CONCLUSIONS: This study provides additional validity evidence for the CALM tool's use in this context if used with multiple raters, aligning with data from the previous simulation-based CALM validity study. Further development may improve reliability. It also serves as an exemplar of the rigors of conducting validity work within medical simulation.

Fitting parametric random effects models in very large data sets with application to VHA national data.

BACKGROUND: With the current focus on personalized medicine, patient/subject level inference is often of key interest in translational research. As a result, random effects models (REM) are becoming popular for patient level inference. However, for very large data sets that are characterized by large sample size, it can be difficult to fit REM using commonly available statistical software such as SAS since they require inordinate amounts of computer time and memory allocations beyond what are available preventing model convergence. For example, in a retrospective cohort study of over 800,000 Veterans with type 2 diabetes with longitudinal data over 5 years, fitting REM via generalized linear mixed modeling using currently available standard procedures in SAS (e.g. PROC GLIMMIX) was very difficult and same problems exist in Stata's gllamm or R's lme packages. Thus, this study proposes and assesses the performance of a meta regression approach and makes comparison with methods based on sampling of the full data. DATA: We use both simulated and real data from a national cohort of Veterans with type 2 diabetes (n=890,394) which was created by linking multiple patient and administrative files resulting in a cohort with longitudinal data collected over 5 years. METHODS AND RESULTS: The outcome of interest was mean annual HbA1c measured over a 5 years period. Using this outcome, we compared parameter estimates from the proposed random effects meta regression (REMR) with estimates based on simple random sampling and VISN (Veterans Integrated Service Networks) based stratified sampling of the full data. Our results indicate that REMR provides parameter estimates that are less likely to be biased with tighter confidence intervals when the VISN level estimates are homogenous. CONCLUSION: When the interest is to fit REM in repeated measures data with very large sample size, REMR can be used as a good alternative. It leads to reasonable inference for both Gaussian and non-Gaussian responses if parameter estimates are homogeneous across VISNs.

Exploring learning effectiveness for participant roles during healthcare simulation.

BACKGROUND: Universities face challenges in preparing future nurses for the workforce. It is essential to guide educators on strategies to achieve similar learning objectives to overcoming these challenges. Educators widely use the observer role in simulation, but researchers do not study the role thoroughly in current simulation research. There is a lack of discipline-specific research exploring how observers learn in simulation and if they can engage in the experiential learning intended in the simulation activity. OBJECTIVES: The objective of this research is to determine the difference in simulation effectiveness between the process-based role versus the response-based role (observers) in participants during simulation-based learning experiences. DESIGN: This research used a quasi-experimental posttest only design to determine differences in simulation effectiveness among learner roles using the Simulation Effectiveness Tool-Modified (SET-M). SETTING & PARTICIPANTS: The researcher collected data from 193 prelicensure nursing students enrolled in any semester of one Midwestern undergraduate baccalaureate nursing program. METHODS: Nursing students completed the assigned face-to-face simulations in their current curriculum plan. Each participant was randomly assigned to a participant role: direct participant role as either a primary or secondary nurse, non-directed observer with no briefing or observer guide, direct observer with an observation guide, or in-scenario observer assigned to a non-clinical or other professional role within the scenario. After debriefing of the simulation, participants completed the demographic survey and SET-M. RESULTS: There were no significant differences found in prelicensure nursing students' simulation effectiveness among the four participant roles studied. CONCLUSION: This study suggests simulation effectiveness (learning and confidence) happens regardless of the participants role during the simulation activity. Educators should consider what roles are necessary within each scenario and assign observation roles as needed.

Home infusion pharmacy quality improvement for central venous access devices using anti-reflux needleless connectors to reduce occlusions, emergency room visits, and alteplase costs.

PURPOSE: The study's purpose was to measure the impact of anti-reflux needleless connector usage in prevention of intraluminal thrombotic occlusions among central venous catheters, as represented by alteplase usage, in a home infusion patient population. METHODS: An18-month before-and-after cohort study of a single home infusion intervention was conducted to compare occlusion outcomes with use of two types of needleless connectors-neutral and anti-reflux-in preventing catheter occlusions, which have been reported to occur in 28% of home infusion patients, resulting in treatment delays, increased nursing encounters and emergency room visits, and higher overall pharmacy costs for supplies and alteplase. RESULTS: A total of 552,707 patient therapy days were studied: 42.5% in the neutral needleless connector group (n = 235,004 therapy days) and 57.5% in the anti-reflux needleless connector group (n = 317,703 therapy days). The rate of alteplase usage with neutral versus anti-reflux needleless connectors was 4.4% versus 2.2% per 1,000 therapy days, with median alteplase use of 112 (95% CI, 89-169) units versus 82 (95% CI, 68-109) units (P < 0.001). Implementation of anti-reflux connectors reduced occlusions and alteplase usage by 48%. CONCLUSION: Statistical evidence demonstrated that use of anti-reflux needleless connectors with central venous access devices reduced the need for alteplase in the study population. Since 10% of patient occlusions were within 7 days after home infusion admission, future research may indicate that placement of anti-reflux needleless connectors at the time of in-hospital insertion can improve patient outcomes. This quality improvement measure reduced central catheter occlusions, alteplase costs, and the number of required nursing and emergency room visits.
