The Perceived Value of Certification in Nonsurgical Pain Management.

Chronic pain is a growing epidemic in America. Challenges in patients' access to care, and in reimbursement to Certified Registered Nurse Anesthetists (CRNAs) who provide pain services, have resulted in a voluntary subspecialty certification in nonsurgical pain management (NSPM) for CRNAs. An evaluation was conducted of perceptions of CRNAs toward the value of certification in NSPM. An invitation to complete the Perceived Value of Certification Tool (PVCT) was sent to 474 CRNAs who identified the subspecialty practice of NSPM upon application for recertification to the NBCRNA. Data were collected on 18 factors related to the perceived value of certification in the NSPM subspecialty. Exploratory factor analysis using principal components analysis with varimax rotation was conducted to assess the latent structure of the PVCT and to identify potential constructs of CRNAs' perceptions. Reliability was assessed using Cronbach α coefficients. Of 64 CRNAs who provided data, a 3-factor solution emerged that explained 72.25% of the overall variance: personal satisfaction, professional recognition, and competence, each with excellent to good reliability (F1: α = 0.95, F2: α = 0.94, F3: α = 0.88). Identification of the 3 constructs in this study will assist with future efforts of examination validation for the subspecialty of NSPM certification for CRNAs.

Computer-Based Case Simulations for Assessment in Health Care: A Literature Review of Validity Evidence.

Simulation for education and training in health-care professions has been widely applied. However, its value as an assessment tool for competence is not fully known. Logistical barriers of simulation-based assessments have led some health-care organizations to utilize computer-based case simulations (CCSs) for assessment. This article provides a review of the literature on the identification of psychometrically sound, CCS instruments designed to measure decision-making competence in health-care professionals. CINAHL, MEDLINE, and Ovid databases identified 84 potentially relevant articles published between January 2000 and May 2017. A total of 12 articles met criteria for inclusion in this review. Findings of these 12 articles indicate that summative assessment in health care using CCSs in the form of clinical scenarios is utilized to assess higher order performance aspects of competence in the form of decision-making. Psychometric strength was validated in eight articles and supported by four replication studies. Two of the eight articles reported evidence of construct validity and support the need for evidence based on a theoretical framework. This literature review offers implications for further research on the use of CCS tools as a method for assessment of competence in health-care professionals and the need for psychometric evidence to support it.

Safety of Rolled and Folded Cotton Blankets Warmed in 130°F and 200°F Cabinets.

PURPOSE: In 2014, ECRI recommended that blanket warming cabinets be set at a maximum temperature of 130°F because of safety concerns with warmed rolled and folded blankets. We could find no research to support this recommendation. The purpose of this study was to measure skin temperatures and thermal comfort in healthy volunteers before and after application of folded and rolled dry cotton blankets warmed in 130°F or 200°F cabinets. DESIGN: Randomized, descriptive, and comparative study. METHODS: Participants (n = 20) received two blankets (one rolled and one folded) from warming cabinets set at 130°F or 200°F. Folded blankets were applied to the back and rolled to the neck. Skin temperatures and thermal comfort were obtained at fixed time intervals. FINDINGS: Skin temperatures from blankets in the 200°F cabinet were greater than those in the 130°F cabinet. No skin temperatures reached temperature and/or duration thresholds for dermal injury. CONCLUSIONS: This study provides supportive evidence that warming cabinets may be set at a maximum of 200°F without compromising patient safety.

Assessing the Psychometric Properties of Alternative Items for Certification.

Alternative items were added as scored items to the National Certification Examination for Nurse Anesthetists (NCE) in 2010. A common concern related to the new items has been their measurement attributes. This study was undertaken to evaluate the psychometric impact of adding these items to the examination. Candidates had a significantly higher ability estimate in alternative items than in multiple choice questions and 6.7 percent of test candidates performed significantly differently in alternative item formats. The ability estimates of multiple choice questions correlated at r = .58. The alternative items took significantly longer time to answer than standard multiple choice questions and discriminated to a higher degree than MCQs. The alternative items exhibited unidimensionality to the same degree as MCQs and the BIC confirmed the Rasch model as acceptable for scoring. The new item types were found to have acceptable attributes for inclusion in the certification program.

Thermal comfort and safety of cotton blankets warmed at 130°F and 200°F.

BACKGROUND: In 2009, the ECRI Institute recommended warming cotton blankets in cabinets set at 130°F or less. However, there is limited research to support the use of this cabinet temperature. PURPOSE: To measure skin temperatures and thermal comfort in healthy volunteers before and after application of blankets warmed in cabinets set at 130 and 200°F, respectively, and to determine the time-dependent cooling of cotton blankets after removal from warming cabinets set at the two temperatures. DESIGN: Prospective, comparative, descriptive. METHODS: Participants (n = 20) received one or two blankets warmed in 130 or 200°F cabinets. First, skin temperatures were measured, and thermal comfort reports were obtained at fixed timed intervals. Second, blanket temperatures (n = 10) were measured at fixed intervals after removal from the cabinets. FINDING: No skin temperatures approached levels reported in the literature that cause epidermal damage. Thermal comfort reports supported using blankets from the 200°F cabinet, and blankets lost heat quickly over time. CONCLUSIONS: We recommend warming cotton blankets in cabinets set at 200°F or less to improve thermal comfort without compromising patient safety.
