Students' perceptions of their learning experiences using high-fidelity simulation to teach concepts relative to obstetrics.

In this era of expanding technology, amidst a shortage of nursing faculty and clinical sites, there has been increasing emphasis on the use of simulation to enhance clinical learning. The purpose of this qualitative, descriptive study was to describe students' self-perceptions of their learning experiences using high-fidelity simulation in teaching concepts relative to obstetrics. A sample of 60 second-year associate of science in nursing (ASN) students attended simulation experiences in obstetrics in addition to required clinical time in a hospital. At the end of each simulated learning experience, students audiotaped their reflections of the experience. Content analysis was done to identify themes in the students' perceptions relative to their learning. Three themes were identified from the analysis: the nonthreatening environment, enhancement of learning, and feeling prepared for practice.

Peak flow monitoring in pediatric asthma management: a clinical practice column submission.

Peak expiratory flow (PEF) monitoring has long been a mainstay of asthma management, but controversy surrounds its efficacy in the pediatric population, and little published research exists on the subject. PEF is both effort and technique dependent and is not suitable for use in children under the age of 5 or with developmental disabilities. However, PEF is useful for monitoring airway changes if used properly, especially in that segment of the population labeled as "poor perceivers" of worsening symptoms. The authors review existing literature on the subject, including the newly revised National Heart, Lung, and Blood Institute (National Heart, Lung, and Blood Institute, National Institutes of Health, U.S. Department of Health and Human Services. (2007). Expert panel report 3: Guidelines for the diagnosis and management of asthma-full report 2007.

The 20 item oral mucositis index: reliability and validity in bone marrow and stem cell transplant patients.

Precise quantification of oral complications in cancer patients receiving bone marrow and stem cell transplantation is essential when testing new treatment strategies for mucositis. Using 133 adult transplant patients, the authors evaluated the 20 item oral mucositis index (OMI), adapted from the 34 item OMI, to facilitate use by nondental health professionals. The OMI-20 consists of nine items measuring erythema, nine measuring ulceration, one measuring atrophy, and one measuring edema; all are scored from 0 = none to 3 = severe and summed for a total possible score of 0-60. The two sets of nine items measuring erythema and ulceration can also be summed separately to produce subscale scores ranging from 0 to 27. Results demonstrated internal consistency, test-retest, and inter-rater reliability, and strong evidence of construct validity. Provided that clinical examiners have appropriate training and experience, the OMI-20 can be used as a reliable, valid, and quantifiable measure of mucositis in clinical research.
