Testing for viral penetration of non-latex surgical and examination gloves: a comparison of three methods
ABSTRACTCurrently, there are no international standards based on microbiological methodology for testing the ability of medical examination or surgical gloves to prevent the passage of viruses. Three protocols for the direct examination of the viral barrier properties of non-latex gloves were compared with 1080 gloves (270 gloves from each of two surgical brands and two medical examination brands). In two of the methods, gloves were filled with and suspended in a nutrient broth solution, and bacteriophage Ï•X174 was placed either inside or outside the glove, while the entire test vessel was agitated. Gloves tested using the third method were filled with a suspension of bacteriophage and allowed to rest in a vessel containing nutrient broth. Gloves were tested directly from the manufacturer's packaging, or after being punctured intentionally or subjected to a stress protocol. The passage of bacteriophage was detected with plaque assays. Significant differences in failure rates between glove brands were apparent only among gloves that had been subjected to the stress protocol. Overall, the two methods in which bacteriophage were placed inside the gloves provided more sensitivity than the method in which bacteriophage was spiked into broth outside the gloves. Thus the placement of bacteriophage inside test gloves (or the use of pressure across the glove barrier during testing), and the use of a standardised stress protocol, will improve significantly the ability of a glove test protocol to determine the relative quality of the barrier offered by medical examination and surgical gloves. Further research is needed to provide test methods that can incorporate reproducibly both the use of bacteriophage and simulated glove use in an industrial quality control setting
Salud internacional: el nuevo desafÃo para la educación de enfermerÃa
A survey was conducted among 110 Schools of Nursing in USA and 5 Schools in Latin America and the Caribbean (LAC) to identify the international health (IH) component in nursing education, practice and research. A significant part of U.S. schools and all 5 LAC schools have international activities, and this interest has started basically in the last 5 to 10 years. There was difference in the structure of IH activities among U.S. and LAC nursing schools, but they were similar in the type of support offered to IH initiatives. IH content in nursing education among U.S. schools was related to culture, health systems and community health; in LAC schools, IH content was related to health promotion, health policy and strategies and nursing perspectives. U.S. and LAC schools with international activities have only 10% of their faculty and students involved with IH initiatives. The nursing schools still lack courses and activities that the Schools of Public Health have implemented to deal with IH. The article observes areas that need to be strengthened so that nursing professionals can expand their leadership roles in research and practice in international health.Para identificar las actividades de salud internacional (SI) en escuelas de enfermerÃa y analizarlas en forma preliminar, se utilizó una muestra de 110 escuelas norteamericanas y, paralelamente, se enviaron cuestionarios a 4 escuelas latinoamericanas y a una del Caribe (ALC). Parte significativa de las escuelas norteamericanas y todas las 5 escuelas de ALC tienen actividades de salud internacional. Dicho interés es básicamente un fenómeno de los últimos cinco a dez años. Hubo diferencias en la estructura de las actividades de SI entre las escuelas, pero el tipo de apoyo ofrecido para actividades internacionales era similar, tanto en los EEUU como en ALC. El componente de SI en el currÃculo de las escuelas norteamericanas estaba dentro de cursos sobre cultura, sistemas de salud y salud de la comunidad, en cuanto en las escuelas de ALC dicho componente estaba en cursos relacionados con promoción de la salud, polÃticas y estrategias de salud y perspectivas de enfermerÃa. Esas escuelas tienen sólamente 10% de sus profesores y estudiantes involucrados en actividades de salud internacional. Se verificó que las escuelas de enfermerÃa todavÃa no hacen parte de los cursos y actividades que las Escuelas de Salud Pública han implementado en ese campo y se observan áreas que deben ser fortalecidas para que la enfermerÃa ocupe una posición de liderazgo en la práctica y la investigación en salud internacional
Patterns of Risk of Depressive Symptoms Among HIV-Positive Women in the Southeastern United States
Depressive symptoms are a common response to HIV disease, and women appear to be at particularly high risk. The authors report results from a crosssectional analysis of data collected from 280 rural women with HIV/AIDS in the Southeastern United States aimed at identifying risk factors of depressive symptoms. Stress theory provided a framework for identification of potential risk factors. Descriptive statistics, measures of association, and regression analyses were used to systematically identify patterns of risk. The final regression model included 22 factors that accounted for 69% of the variance in depressive symptoms. The majority of variance in depressive symptoms was accounted for by only six variables: the frequency of HIV symptoms, recent experiences of sadness/hopelessness, the availability of social support, and the use of three coping strategies: living positively with HIV, isolation/withdrawal, and denial/avoidance. The results suggest a number of intervention strategies for use with rural women with HIV/AIDS
Outcome of Occupational Latex Allergy—Work Ability and Quality of Life
OBJECTIVE: The quality of life (QOL) and work ability of health care workers allergic to natural rubber latex (NRL) were assessed after implementation of regulations on powder-free NRL gloves in Germany. METHODS: 196 HCW with reported NRL allergy answered a questionnaire (response rate 58%) containing the Work Ability Index (WAI), Mini Asthma Quality of Life Questionnaire (MiniAQLQ), and Dermatology Life Quality Index (DLQI). RESULTS: 63.2% still had NRL-related symptoms during the last 6 month. However on a scale from 0 to 10, the intensity of NRL-related symptoms decreased from 8.5 before to 2.3 after implementation of regulations on powder-free NRL gloves. A higher number of subjects were able to avoid NRL in the private than in the work environment (85% vs. 61%). NRL-related symptoms decreased and WAI increased with successful avoidance of NRL at workplace (b = 0.23, p = 0.003). QOL was only little affected by NRL allergy (mean: MiniAQLQ = 6.0; DLQI = 4.1). CONCLUSIONS: Although there was improvement after implementation of powder-free NRL gloves, there is still a considerable number of HCW with NRL-related symptoms. Further investigations on latex avoidance and the cause of persisiting allergic symptoms in HCW with NRL allergy are therefore needed

Moving beyond hand hygiene monitoring as a marker of infection prevention performance: Development of a tailored infection control continuous quality improvement tool.
BACKGROUND: Infection control practice compliance is commonly monitored by measuring hand hygiene compliance. The limitations of this approach were recognized in 1 acute health care organization that led to the development of an Infection Control Continuous Quality Improvement tool.
METHODS: The Pronovost cycle, Barriers and Mitigation tool, and Hexagon framework were used to review the existing monitoring system and develop a quality improvement data collection tool that considered the context of care delivery.
RESULTS: Barriers and opportunities for improvement including ambiguity, consistency and feasibility of expectations, the environment, knowledge, and education were combined in a monitoring tool that was piloted and modified in response to feedback. Local adaptations enabled staff to prioritize and monitor issues important in their own workplace. The tool replaced the previous system and was positively evaluated by auditors. Challenges included ensuring staff had time to train in use of the tool, time to collect the audit, and the reporting of low scores that conflicted with a target-based performance system.
CONCLUSIONS: Hand hygiene compliance monitoring alone misses other important aspects of infection control compliance. A continuous quality improvement tool was developed reflecting specific organizational needs that could be transferred or adapted to other organizations

Validity of hand hygiene compliance measurement by observation: A systematic review
BACKGROUND: Hand hygiene is monitored by direct observation to improve practice, but this approach can potentially cause information, selection, and confounding bias, threatening the validity of findings. The aim of this study was to identify and describe the potential biases in hand hygiene compliance monitoring by direct observation; develop a typology of biases and propose improvements to reduce bias; and increase the validity of compliance measurements.
METHODS: This systematic review of hospital-based intervention studies used direct observation to monitor health care workers' hand hygiene compliance.
RESULTS: Seventy-one publications were eligible for review. None was free of bias. Selection bias was present in all studies through lack of data collection on the weekends (n = 61, 86%) and at night (n = 46, 65%) and observations undertaken in single-specialty settings (n = 35, 49%). We observed inconsistency of terminology, definitions of hand hygiene opportunity, criteria, tools, and descriptions of the data collection. Frequency of observation, duration, or both were not described or were unclear in 58 (82%) publications. Observers were trained in 56 (79%) studies. Inter-rater reliability was measured in 26 (37%) studies.
CONCLUSIONS: Published research of hand hygiene compliance measured by direct observation lacks validity. Hand hygiene should be measured using methods that produce a valid indication of performance and quality. Standardization of methodology would expedite comparison of hand hygiene compliance between clinical settings and organizations
