The Nature of Nursing Competency in Simulation of Adult Medical-Surgical Nursing: Exploratory Factor Analysis.

BACKGROUND AND PURPOSE: Educators, employers, and regulatory agencies face substantive challenges in evaluating nursing competency. Evidence on what competency is and how to measure it can mitigate the challenges. METHODS: Participants (N = 67) completed three high-fidelity simulation tests. Each video-recorded test was scored by three raters using a 41-item instrument. Exploratory factor analysis was used to define the latent structure of the instrument. RESULTS: A five-factor solution accounted for 56% of the variance, minimized negative loadings, and minimized the number of cross-loadings. The factors were minimally correlated (each r < .30). CONCLUSIONS: The factors, Vigilant Action, Role Nuances, Precision, Procedural Skills, and Risk Reduction, represent integrated dimensions of competency that can be linked to specific tasks underlying safe practice.

Testing Nursing Competence: Validity and Reliability of the Nursing Performance Profile.

BACKGROUND AND PURPOSE: There is growing evidence that simulation testing is appropriate for assessing nursing competence. We compiled evidence on the validity and reliability of the Nursing Performance Profile (NPP) method for assessing competence. METHODS: Participants (N = 67) each completed 3 high-fidelity simulation tests; raters (N = 31) scored the videotaped tests using a 41-item competency rating instrument. RESULTS: The test identified areas of practice breakdown and distinguished among subgroups differing in age, education, and simulation experience. Supervisor assessments were positively correlated, r = .31. Self-assessments were uncorrelated, r = .07. Interrater agreement ranged from 93% to 100%. Test-retest reliability ranged from r = .57 to .69. CONCLUSIONS: The NPP can be used to assess competence and make decisions supporting public safety.

Standardized Testing Practices: Effect on Graduation and NCLEX® Pass Rates.

The use standardized testing in pre-licensure nursing programs has been accompanied by conflicting reports of effective practices. The purpose of this project was to describe standardized testing practices in one states' nursing programs and discover if the use of a cut score or oversight of remediation had any effect on (a) first time NCLEX® pass rates, (b) on-time graduation (OTG) or (c) the combination of (a) and (b). Administrators of 38 nursing programs in one Southwest state were sent surveys; surveys were returned by 34 programs (89%). Survey responses were compared to each program's NCLEX pass rate and on-time graduation rate; t-tests were conducted for significant differences associated with a required minimum score (cut score) and oversight of remediation. There were no significant differences in NCLEX pass or on-time graduation rates related to establishment of a cut score. There was a significant difference when the NCLEX pass rate and on-time graduation rate were combined (Outcome Index "OI") with significantly higher program outcomes (P=.02.) for programs without cut-scores. There were no differences associated with faculty oversight of remediation. The results of this study do not support establishment of a cut-score when implementing a standardized testing.

Intracoronary Brachytherapy for Recurrent Drug-Eluting Stent Failure.

OBJECTIVES: The study sought to report safety and long-term clinical efficacy of intravascular brachytherapy (VBT) for recurrent drug-eluting stent in-stent restenosis (DES-ISR). BACKGROUND: Recurrent DES-ISR remains a therapeutic challenge, and VBT has been used selectively in recurrent DES failure. METHODS: Patients undergoing VBT for recurrent DES-ISR were enrolled from a percutaneous coronary intervention registry. Clinical, procedural, VBT, and outcome data were collected for DES-ISR treated with radiation. Follow-up was obtained by phone call and clinic visits. RESULTS: A total of 186 patients (283 lesions) were included. Mean age was 65 ± 11 years, and 115 (61.8%) were men. Mean time to failure from last failed DES implantation was 450.65 ± 50 days. Majority (95%) had >2 episodes of target lesion revascularization (TLR). Commonest presentation of DES-ISR was unstable angina (68, 30%). All lesions were treated with balloon angioplasty followed by VBT using Beta-Cath system (Best Vascular Inc., Springfield, Virginia) with a dose of 23 to 25 Gy at 2 mm from source center. Radiation was delivered to site of ISR, without procedural adverse events, in 99% cases. Incidence of TLR was 3.3% at 6 months, 12.1% at 1 year, 19.1% at 2 years, and 20.7% at 3 years. No subacute thrombosis event was noted. One patient had late thrombosis during a 3-year follow-up. CONCLUSIONS: VBT for recurrent DES-ISR is safe, with low recurrence rates at 12 months post-procedure, and can be safely used as an effective short-term strategy. Overtime, there is a gradual attrition in patency requiring repeat intervention.

Beta radiation for renal nerve denervation: initial feasibility and safety.

AIMS: In small clinical trials, sympathetic renal denervation using radiofrequency (RF) energy shows promise in treating resistant hypertension. However, the RF procedure is lengthy and is associated with pain during ablation. Vascular brachytherapy, a proven treatment for in-stent restenosis, has the potential to cause nerve fibrosis. The purpose of the present study was to assess the safety and feasibility of renal artery brachytherapy for sympathetic renal denervation. METHODS AND RESULTS: A total of 10 normotensive domestic swine underwent vascular brachytherapy to left and right renal arteries using the Beta-Cath 3.5 Fr delivery system at doses of 25 Gy (n=8) and 50 Gy (n=8) at 2 mm from the source centre. These groups were compared to untreated arteries that served as control (n=4). Follow-up obtained at one or two months included angiogram, intravascular ultrasound, and histopathology analysis. The vascular brachytherapy procedure was safe and no apparent angiographic or ultrasound injuries to the vessel were seen. Histology showed a varying degree of thermal injury more pronounced in the 50 Gy group. The majority of examined nerves showed some degree of injury; there was a dose-related effect on nerve injury severity. There were varying degrees of arteriolar changes in the examined sections, with most showing a 2-20% degree of endothelial cell loss. CONCLUSIONS: This initial feasibility and safety study of renal nerve denervation, mediated by low and intermediate ß-radiation dosages, indicates that this approach can cause nerve fibrosis while avoiding significant damage to the renal artery.

Measuring competence: collaboration for safety.

Few options are available to nursing regulatory boards for the evaluation of nursing competency in registered nurses who are reported for practice breakdown. To address this deficiency, the authors conducted funded research through collaboration between their respective institutions: a state nursing regulatory board, a community college nursing program, and a state university nursing program. Through this collaboration, a competency evaluation process that used high-fidelity simulation was developed and was called the nursing performance profile (NPP). The NPP process consisted of evaluation of videotaped performances of registered nurses providing simulated patient care in three successive situations. Nurses who were experienced in both practice and supervision rated the performances according to scoring guidelines developed by the authors. Findings showed that the NPP process has the potential to (1) provide regulators, educators, and employers with a quantitative picture of nurse performance across nine areas essential to safe practice, and (2) establish a basis for recommending a specific remediation plan or continuing professional development.

Developing a statewide medication technician pilot program in nursing homes.

In times of fiscal constraints, nursing homes are seeking to maximize use of licensed staff through delegation of low-risk tasks to unlicensed personnel. Between 2004 and 2008, the Arizona State Board of Nursing developed and conducted a pilot program to determine the impact on patient health and safety of licensed nurses delegating medication administration to trained certified nursing assistants. There were no differences in patterns of medication errors before and after the introduction of medication technicians, and structured interviews revealed that participants viewed the role favorably, with reported increased role satisfaction on the part of delegating nurses. Efforts are underway to extend the program statewide.

Phase II trial of concurrent paclitaxel, carboplatin, and external-beam radiation followed by surgical resection in locally advanced non-small-cell lung cancer, protocol 99-444.

PURPOSE: We conducted a phase II study to evaluate the utility and outcomes of concurrent weekly low-dose chemotherapy with concurrent radiation in an effort to "downstage" patients with locally advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Eighteen patients with pathologically confirmed stage IIIA (T1-3 N2 or T3 N1) and 3 patients with stage IIB (T3 N0) NSCLC were enrolled. Seventeen of 18 patients with stage IIIA cancer had N2 disease. A chemotherapy/radiation schedule consisted of paclitaxel 50 mg/m(2 )and carboplatin administered at an area under the curve of 2 weekly for 5 weeks along with chest irradiation of 45 Gy. Patients with regressed or stable disease upon restaging were considered surgical candidates. Patients deemed inoperable were given additional radiation therapy. RESULTS: Twenty-one patients were enrolled from April 2000 to March 2004. Data from 21 patients were available for evaluation at the time of analysis. Grade 3/4 constitutional and pulmonary toxicity was
