Usability of American Nurses Association State Web Sites: A Follow-up Evaluation.

The American Nurses Association supports professional nurses through Web sites administered by state nursing associations, providing important information for current and potential members. Optimal usability of these Web sites is critical for nurses to obtain the information they seek. Heuristic evaluations are general criteria used to evaluate the usability of technology such as Web sites. A study published in 2014, using heuristic criteria from Nielsen's 10 principles and Health on The Web, evaluated 27 state nursing Web sites to identify usability concerns that could prevent nurses from obtaining accurate information regarding state nursing practice. The purpose of this study is to conduct a second heuristic evaluation to assess for changes in a subset of 12 Web sites. The analysis comparing the evaluation from 2012 to 2014 found that mean scores increased and variance decreased; however, no statistically significant difference was found between the two studies. Scores increased in 2014 for "help users to diagnose, and recover from errors," "match between the system and real world," and "consistency and standards." Scores decreased due to absence of mission statements and identification of intended audience. Ideally, Web site designers will use the feedback from this study and make changes that improve their usability to provide information to nurses.

A new paradigm for biospecimen banking in the personalized medicine era.

Banking of high-quality, appropriately consented human tissue is crucial for the understanding of disease pathogenesis and translation of such knowledge into improvements in patient care. Traditionally, tissue banking has been thought of as primarily an academic research activity, but tissue and biospecimen banking is increasingly assuming clinical importance, especially with the advent of genetic and proteomic testing approaches that rely on fresh or fresh frozen tissue. These approaches are part of the revolution in personalized medicine. This revolution's impact on biorepositories-their mission and day-to-day function-will be profound. Direct patient care will require structuring tissue procurement to become a routine part of patient care. Accordingly tissue banking will expand from its traditional research role in large academic medical centers into the everyday practice of surgical pathology. Successful implementation of this model will require consideration of several financial, medicolegal, and administrative issues.

Prevalence of undiagnosed obstructive sleep apnea among adult surgical patients in an academic medical center.

BACKGROUND: Obstructive sleep apnea (OSA) affects approximately 20% of US adults, of whom about 90% are undiagnosed. While OSA may increase risk of perioperative complications, its prevalence among surgical patients is unknown. We tested the feasibility of screening surgical patients for OSA and determined the prevalence of undiagnosed OSA. METHODS: In a prospective, observational study adult surgical patients were screened for OSA in an academic hospital. Patients without an OSA diagnosis who screened high-risk were offered a home sleep study to determine if they had OSA. The results were compared with polysomnography (PSG) when available. Charts of high-risk patients were examined for postoperative complications. High-risk patients received targeted interventions as part of a hospital safety initiative. RESULTS: There were 2877 patients screened; 661 (23.7%) screened high-risk for OSA, of whom 534 (81%) did not have diagnosed OSA. The portable sleep study detected OSA in 170/207 (82%) high-risk patients without diagnosed OSA. Twenty-six PSGs confirmed OSA in 19 of these patients. Postoperatively there were no respiratory arrests, two unanticipated ICU admissions, and five documented respiratory complications. CONCLUSION: Undiagnosed OSA is prevalent in adult surgical patients. Implementing universal screening is feasible and can identify undiagnosed OSA in many surgical patients. Further investigation is needed into perioperative complications and their prevention for patients with undiagnosed OSA.
