Activated chlorine dioxide solution can be used as a biocompatible antiseptic wound irrigant.

OBJECTIVE: The purpose of this study was to compare cosmesis at 3 to 4 months and infection in simple lacerations irrigated with normal saline (NS) versus activated chlorine dioxide (CD). DESIGN: This was a prospective, randomized trial of a convenience sample of patients. This study was approved by the institutional review board and Food and Drug Administration as a physician-sponsored trial (FDA investigational new drug no. 68762). SETTING: The study was conducted in a large urban, academic emergency department. PATIENTS: Patients aged 18 to 100 with simple, uncomplicated lacerations requiring repair that were less than 8 hours old were enrolled. INTERVENTIONS: Patients were randomized to receive either NS or CD wound irrigation. MAIN OUTCOME MEASURES: Demographics, infection, and cosmesis were analyzed and assessed. Cosmetic outcome was assessed at 3 to 4 months using a visual analog scale (VAS), wound evaluation score (WES), patient VAS (VASPt), and digital imaging VAS by 2 plastic surgeons (VASPlast). MAIN RESULTS: One hundred ninety-three patients were enrolled. Data analysis was available for 175 cases (86 NS and 89 CD). Wound infection follow-up was obtained in 74.9% of the patients. The 3- to 4-month cosmesis follow-up was 37.7% for VAS/WES, 40.0% for VASPt, and 37.7% for VASPlast. There were no significant differences in demographics, key wound characteristics, infection, adverse reactions, and cosmesis. CONCLUSION: The authors report the use of a novel antimicrobial irrigation solution. Chlorine dioxide appears to be a safe biologically acceptable antiseptic wound irrigant that does not appear to interfere with cosmetic outcomes.

Use of in situ simulation and human factors engineering to assess and improve emergency department clinical systems for timely telemetry-based detection of life-threatening arrhythmias.

BACKGROUND AND OBJECTIVES: Medical simulation and human factors engineering (HFE) may help investigate and improve clinical telemetry systems. Investigators sought to (1) determine the baseline performance characteristics of an Emergency Department (ED) telemetry system implementation at detecting simulated arrhythmias and (2) improve system performance through HFE-based intervention. METHODS: The prospective study was conducted in a regional referral ED over three 2-week periods from 2010 to 2012. Subjects were clinical providers working at the time of unannounced simulation sessions. Three-minute episodes of sinus bradycardia (SB) and of ventricular tachycardia (VT) were simulated. An experimental HFE-based multi-element intervention was developed to (1) improve system accessibility, (2) increase system relevance and utility for ED clinical practice and (3) establish organisational processes for system maintenance and user base cultivation. The primary outcome variable was overall simulated arrhythmia detection. Pre-intervention system characterisation, post-intervention end-user feedback and real-world correlates of system performance were secondary outcome measures. RESULTS: Baseline HFE assessment revealed limited accessibility, suboptimal usability, poor utility and general neglect of the telemetry system; one simulated VT episode (5%) was detected during 20 pre-intervention sessions. Systems testing during intervention implementation recorded detection of 4 out of 10 arrhythmia simulations (p=0.03). Twenty post-intervention sessions revealed more VT detections (8 of 10) than SB detections (3 of 10) for a 55% overall simulated arrhythmia detection rate (p=0.001). CONCLUSIONS: Experimental investigations helped reveal and mitigate weaknesses in an ED clinical telemetry system implementation. In situ simulation and HFE methodologies can facilitate the assessment and abatement of patient safety hazards in healthcare environments.

High risk health behaviors and healthcare access among female adult entertainment club employees.

BACKGROUND: Prior studies of adult entertainment club employees have been qualitative and lacked information regarding a range of important health factors. METHODS: Sixty-nine female club employees completed a computer-assisted survey on healthcare access and health behaviors. An age-matched comparison sample was obtained from the Behavioral Risk Factor Surveillance System. Researchers calculated descriptive characteristics and developed multivariable logistic regression models to provide the adjusted odds of health factors. RESULTS: In the combined study sample, the mean age was 28.5 years; 75% were white, 20% Hispanic/Latino; 58% were single; 46% had at least one child. Compared to the Behavioral Risk Factor Surveillance System sample, significantly fewer club employees had health insurance or a primary care provider, and more reported not seeing a physician due to cost. Club employees had significantly higher adjusted odds of smoking (aOR 4.38, 95% CI 1.13-16.88), high-risk drinking (aOR 5.68, 95% CI 1.73-18.67), HIV risk factors (aOR 4.91, 95% CI 1.26-28.2), and lower odds of HIV testing (aOR 0.10, 95% CI 0.04-0.27) than the comparison group. CONCLUSIONS: Compared to a national sample of women, more club employees reported high-risk drinking and HIV risk behaviors, and fewer reported HIV testing and access to healthcare. Adult club employees may benefit from interventions to reduce harmful behaviors and increase healthcare access.

Global emergency medicine: a review of the literature from 2011.

OBJECTIVES: The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of published and unpublished articles relevant to global emergency medicine (EM) to identify, review, and disseminate the most important research in this field to a wide audience of academics and practitioners. METHODS: This year, 7,924 articles written in seven languages were identified by our search. These articles were divided up among 20 reviewers for initial screening based on their relevance to the field of global EM. An additional two reviewers searched the grey literature. A total of 206 articles were deemed appropriate by at least one reviewer and approved by their editor for formal scoring of their overall quality and importance. RESULTS: Of the 206 articles that met our predetermined inclusion criteria, 24 articles received scores of 17 or higher and were selected for formal summary and critique. Interrater reliability for our scoring system was good with an interclass correlation coefficient of 0.628 (95% confidence interval = 0.51 to 0.72). CONCLUSIONS: Compared to previous reviews, there was a significant increase in the number of articles that were devoted to emergency care in resource-limited settings, with fewer articles related to disaster and humanitarian response. The majority of articles that met our selection criteria were reviews that examined the efficacy of particular treatment regimens for diseases that are primarily seen in low- and middle-income countries.

Web survey and embedded intervention on emergency department personnel perceptions of role in patient experience.

Investigators examined emergency department (ED) personnel's perceived job responsibilities and insights into determinants of patient experience. Surveys queried subjects on their perceptions of select clinical care-related actions (CCAs) to assess discipline-specific and service-specific CCA ownership and valuation. Investigators surveyed 153 of 634 ED personnel. A total of 3047 responses to 3802 queries indicated that a specified CCA was 'always' (58.2%) or 'sometimes' (21.9%) the subject's responsibility. A total of 3645 of 3797 responses indicated the CCA specified was 'always' (84.2%) or 'sometimes' (11.8%) important to the patient experience. Twelve percent of subjects reported not being responsible for monitoring or correcting medical errors. After exposure to survey queries, subjects indicated changing or re-considering how they communicate with patients (28.1%), deliver clinical care (20.2%), and arrange disposition/follow-up (20.3%). ED personnel's perceptions of CCA ownership and importance to patient experience were assessed. Subjects reported detectable levels of anticipated job-related behavioral changes traceable to survey-embedded intervention.

International emergency medicine: a review of the literature from 2010.

The International Emergency Medicine (IEM) Literature Review aims to highlight and disseminate high-quality global EM research in the fields of EM development, disaster and humanitarian response, and emergency care in resource-limited settings. For this review, we conducted a Medline search for articles published between January 1 and December 31, 2010, using a set of international and EM search terms and a manual search of journals that have produced large numbers of IEM articles for past reviews. This search produced 6,936 articles, which were divided among 20 reviewers who screened them using established inclusion and exclusion criteria to select articles relevant to the field of IEM. Two-hundred articles were selected by at least one reviewer and approved by an editor for scoring. Two independent reviewers using a standardized and predetermined set of criteria then scored each of the 200 articles. The 27 top-scoring articles were chosen for full review. The articles this year trended toward evidence-based research for treatment and care options in resource-limited settings, with an emphasis on childhood illness and obstetric care. These articles represent examples of high-quality international emergency research that is currently ongoing in high-, middle-, and low-income countries alike. This article is not intended to serve as a systematic review or clinical guideline but is instead meant to be a selection of current high-quality IEM literature, with the hope that it will foster further growth in the field, highlight evidence-based practice, and encourage discourse.
