Background: Peripheral intravenous catheters (PIVs) have been considered as having lower risk of infection than central lines. However, research is limited regarding numbers of primary bloodstream infections related to peripheral lines and prevention of peripheral line-associated bloodstream infections (PLABSI). Methods: Our aim was to create and monitor compliance with a new PIV maintenance bundle using disinfecting caps and tips and to assess whether this bundle would lead to a decrease in PLABSI rates. Weekly audits were conducted to measure compliance with both the new PIV bundle and our existing central line-associated bloodstream infection (CLABSI) bundle. We also audited the disconnection method used for intravenous line tubing (peripheral and central lines) before and during the study intervention period. Results: A compliance rate of close to 90% with the use of the disinfecting caps and tips was attained. Using a PLABSI bundle successfully decreased primary bloodstream infections due to PIVs (from 0.57 infections per 1000 patient-days preintervention to 0.11 infections per 1000 patient-days; p < 0.001). We confirmed that improving care for PIVs would decrease primary bloodstream infections associated with these devices. Conclusions: Using a PIV maintenance bundle including disinfecting caps and tips can effectively lower the rate of primary bloodstream infections attributable to PIV lines.

Introduction After a train derailment released chlorine gas in Graniteville, South Carolina, in 2005, a multiagency team performed an epidemiologic assessment of chlorine exposure and resulting health effects. Five months later, participants were resurveyed to determine their health status and needs and to assist in planning additional interventions in the community. Methods Questionnaires were mailed to 279 patients interviewed in the initial assessment; follow-up telephone calls were made to nonresponders. The questionnaire included questions regarding duration of symptoms experienced after exposure and a posttraumatic stress disorder (PTSD) assessment tool. Results Ninety-four questionnaires were returned. Seventysix persons reported chronic symptoms related to the chlorine exposure, 47 were still under a doctor's care, and 49 were still taking medication for chlorine-related problems. Agreement was poor between the first and second questionnaires regarding symptoms experienced after exposure to the chlorine (κ=0.30). Forty-four respondents screened positive for PTSD. PTSD was associated with post-exposure hospitalization for three or more nights [relative risk (RR) = 1.7; 95% confidence interval (CI) = 1.1-2.6] and chronic symptoms (RR=9.1; 95% CI=1.3-61.2), but not with a moderate-to-extreme level of chlorine exposure (RR=1.2; 95% CI=0.8-1.8).Conclusions Some victims of this chlorine exposure event continued to experience physical symptoms and continued to require medical care 5 months later. Chronic mental health symptoms were prevalent, especially among persons experiencing the most severe or persistent physical health
