AbstractObjective:Different manufacturers recommend different levels of disinfection for oxygen nipple and nut adaptors, also known as Christmas-tree adaptors (CTAs). We aimed to determine the bacterial contamination rates of CTAs before and after clinical use and whether disinfection wipes effectively eliminate bacteria from CTAs.Methods:CTAs were swabbed for bacteria directly from the shipment box or after use in a medical intensive care unit to determine levels of contamination. CTAs were also inoculated in the laboratory with a variety of bacteria and disinfected with either 0.5% hydrogen peroxide (Oxivir 1) or 0.25% tetra-ammonium chloride with 44.50% isopropyl alcohol (Super Sani-Cloth), and the effectiveness of each wipe was determined by comparing the bacterial recovery before and after disinfection.Results:CTAs exhibit low levels of bacterial burden before and after clinical use. Both disinfecting wipes were effective at removing bacteria from the CTAs.Conclusions:Low-level disinfection of CTAs is appropriate prior to redeployment in the clinical setting.

In 2013, a before-and-after intervention study was conducted to evaluate the effect 24-hour intensivist coverage on length of stay and rates of catheter-associated urinary tract infection, central-line associated blood stream infection, and ventilator-associated events. Intensivist coverage for 24 hours did not decrease length of stay or result in a decrease in any specific infection rate.Infect. Control Hosp. Epidemiol. 2016;37(3):352–354

• Objectives To compare levels of sedation in patients receiving continuous intravenous infusions of sedative/hypnotic or narcotic agents with levels in patients not receiving infusions and to compare subjective (Sedation-Agitation Scale) and objective (Bispectral Index) evaluations of sedation. • Methods Patients receiving mechanical ventilation in a medical intensive care unit were evaluated prospectively. Level of sedation was assessed with the Sedation-Agitation Scale (range 1–7, unarousable to dangerous agitation) and the Bispectral Index (range 0–100, flat line to awake waveform) recorded before and after stimulation. Patients were classified as receiving continuous infusions if an infusion had been administered within 24 hours preceding assessment. • Results Nineteen patients were evaluated on 80 occasions. Scores on the Sedation-Agitation Scale ranged from 1 to 5 (mean 2.6 and median 2) and correlated highly with values for the Bispectral Index (R2 = 0.48 before and 0.44 after stimulation, P < .001). Patients receiving continuous infusions were more deeply sedated than were patients receiving boluses or no medication (mean [SD] scores, Sedation-Agitation Scale: 2.1 [1.2] vs 3.3 [1.0], P < .001; Bispectral Index before stimulation: 63 [24] vs 86 [13], P < .001). Patients receiving continuous infusions were more likely to have a score of 2 or less on the Sedation-Agitation Scale (32/44 vs 8/35, P < .001). • Conclusion Objective and subjective assessments of sedation are highly correlated. Use of continuous infusions is associated with deeper levels of sedation, and patients receiving continuous infusions are more likely to be oversedated. Sedation therapy should be guided by subjective or objective assessment.

Objective.To estimate the level of hand or glove contamination with vancomycin-resistant enterococci (VRE) among healthcare workers (HCWs) who touch a patient colonized with VRE and/or the colonized patient's environment during routine care.Design.Structured observational study.Setting.Medical intensive care unit of a 700-bed, tertiary-care teaching hospital.Participants.VRE-colonized patients and their caregivers.Methods.We obtained samples from sites on the intact skin of 22 patients colonized with VRE and samples from sites in the patients' rooms, before and after routine care, during 27 monitoring episodes. A total of 98 unique HCWs were observed during 131 HCW observations. Observers recorded the sites touched by HCWs. Culture samples were obtained from HCWs' hands and gloves before and after care.Results.VRE were isolated from a mean (±SD) of 55% ± 24% of patient sites (n= 256) and 17% ± 12% of environmental sites (n= 1,572). Most HCWs (131 [56%]) touched both the patient and the patient's environment; no HCW touched only the patient. Of 103 HCWs whose hand samples were negative for VRE when they entered the room, 52% contaminated their hands or gloves after touching the environment, and 70% contaminated their hands or gloves after touching the patient and the environment (P= .101). In a univariate logistic regression model, the risk of hand or glove contamination was associated with the number of contacts made (odds ratio, 1.1 [95% confidence interval, 1.01-1.19). In a multivariate model, the effect of the number of contacts could not be distinguished from the effect of type of contact (ie, touching the environment alone or touching both the patient and the environment). Overall, 37% of HCWs who did not wear gloves contaminated their hands, and 5% of HCWs who wore gloves did so (an 86% difference).Conclusion.HCWs were nearly as likely to have contaminated their hands or gloves after touching the environment in a room occupied by a patient colonized by VRE as after touching the colonized patient and the patient's environment. Gloves were highly protective with respect to hand contamination.

Abstract Background Reprocessing of flexible endoscopes (FEs) is often expensive, time consuming, and becomes increasingly complex, due to rising demands of hygiene. After beneficial results in reprocessing of rigid endoscopes using Impelux™ UV-C light technology, we tested the same method for reprocessing of FEs without working channel. Materials and methods Testing was performed on FEs without working channel after routine clinical use (transnasal flexible endoscopy). Disinfection consisted of mechanical precleaning and 60 s exposure to Impelux™ UV-C light technology. Bacterial contamination was tested on 50 FEs before and after disinfection. Further 50 FEs regarding protein residuals. The absolute effectiveness of the D60 was tested on 50 test bodies (RAMS) with a standardized contamination of 107 colony-forming units (CFU) of Enterococcus faecium. Results The FEs were contaminated with a high average value of 916.7 CFU (± 1057 CFU) after clinical usage. After reprocessing, an average contamination of 2.8 CFU (± 1.6) on 14% (n = 7) of the FEs was detected consisting of non-pathogenic species, the remaining FE were sterile. After reprocessing, all FEs were protein-free (< 1 μg). The artificially contaminated test bodies showed no remaining bacterial contamination after disinfection, resulting in an average absolute germ reduction of about 107 CFU. Conclusion Impelux™ UV-C light technology efficiently reduces bacterial contamination of FEs and might be useful in daily practice.
