Increasing evidence suggests that ambient air pollution is a major risk factor for both acute and chronic respiratory disease exacerbations and emergencies. The objective of this study was to determine the association between ambient air pollutants and emergency department (ED) visits for respiratory conditions in nine districts across the province of Ontario in Canada. Health, air pollutant (PM2.5, NO2, O3, and SO2), and meteorological data were retrieved from April 2004 to December 2011. Respiratory diseases were categorized as: chronic obstructive pulmonary disease (COPD, including bronchiectasis) and acute upper respiratory diseases. A case-crossover design was used to test the associations between ED visits and ambient air pollutants, stratified by sex and season. For COPD among males, positive results were observed for NO2 with lags of 3-6 days, for PM2.5 with lags 1-8, and for SO2 with lags of 4-8 days. For COPD among females, positive results were observed for O3 with lags 2-4 days, and for SO2 among lags of 3-6 days. For upper respiratory disease emergencies among males, positive results were observed for NO2 (lags 5-8 days), for O3, (lags 0-6 days), PM2.5 (all lags), and SO2 (lag 8), and among females, positive results were observed for NO2 for lag 8 days, for O3, PM2.5 among all lags. Our study provides evidence of the associations between short-term exposure to air pollution and increased risk of ED visits for upper and lower respiratory diseases in an environment where air pollutant concentrations are relatively low.

Ceravolo D.J., Schwartz D.G., Foltz-Ramos K.M. & Castner J. (2012) Journal of Nursing Management 20, 599–606 Strengthening communication to overcome lateral violence Aim This quality improvement project aims to reduce nurse-to-nurse lateral violence and create a more respectful workplace culture through a series of workshops. Background Lateral violence is common and pervasive in nursing, with detrimental physical, psychological and organizational consequences. Methods This project describes the organization-wide pre- and post-intervention survey of registered nurses’ perception of lateral violence and turnover. Results After the workshop series, nurses who reported experiencing verbal abuse fell from 90 to 76%. A greater percentage of nurses perceived a workplace that was respectful to others and in which it was safe to express opinions. After the workshop series, a greater percentage of nurses felt determined to solve the problem after an incident of lateral violence, while a smaller percentage felt powerless. Nursing turnover and vacancy rates dropped. Conclusions Educational workshops that enhanced awareness of lateral violence and improved assertive communication resulted in a better working environment, reduction in turnover and vacancy rates, and reduced incidence of lateral violence. Implications for nursing management Nurse managers must raise awareness of lateral violence with individual and organizational consequences. Nursing leadership can effect organizational change to lesson lateral violence and enhance a healthy workplace culture by replicating our intervention or components of our workshops.

The aim of this study was to delineate the multi-level relationships of individual registered nurse (RN) and nursing unit factors on missed nursing care. This was a quantitative model-building study using a descriptive, cross-sectional design. Surveys (N = 553) and administrative unit records from nurses in one hospital system undergoing merger were included. The results showed that 36% of the variation in missed nursing care is due to the unit context, with a corresponding 64% due to individual nurse differences. At the unit level, workload, skill mix, and critical unit type affected the amount of missed nursing care. At the individual nurse level, more experience, supplies problems, communication problems, and involvement in errors of commission all increased the perception of the amount of missed nursing care. Education level was not related to the amount of missed nursing care. The findings highlight the importance of unit- and individual-level interventions to redesign hospital nursing care.
