The incidence of EVD-related infections is high in our hospital, Gram-negative micro-organisms were the most frequent causal agents identified and length of time that the catheter was in place contributed to the infection rate.
BackgroundStudies on the implantation of care routines showed reduction on EVD catheter-related infections rates; however zero tolerance is difficult to be achieved. The objective of this study was to assess the impact of an educational intervention on the maximal reduction on rates of EVD-related infections.Methodology/Principal FindingsThe quasi-experimental (before-after intervention) study occurred in two phases: pre-intervention, from April 2007 to July 2008, and intervention, from August 2008 to July 2010. Patients were followed for 30 days after the removal of the EVD, and EVD-related infections were considered as only those with laboratorial confirmation in the CSF. Observations were made of the care of the EVD and compliance with Hygiene of the Hands (HH), a routine of care was drawn up, training was given, and intervention was made to reduce the time the EVD catheter remained in place.Resultsduring the study, 178 patients were submitted to 194 procedures, corresponding to 1217 EVD catheters-day. Gram-negative agents were identified in 71.4% of the infections during the pre-intervention period and in 60% during the intervention period. During the study, EVD-related infection rates were reduced from 9.5% to 4.8% per patient, from 8.8% to 4.4% per procedure, and the incidence density dropped from 14.0 to 6.9 infections per 1000 catheters-day (p = 0.027). The mortality reduced 12% (from 42% to 30%).Conclusions/SignificanceDuring one year after the fourth intervention, no microbiologically identified infection was documented. In light of these results, educational intervention proved to be a useful tool in reducing these rates and showed also impact on mortality.
Repetitive transcranial magnetic stimulation (rTMS) can induce significant antidepressant effects and, for some patients, might be an alternative to electroconvulsive therapy (ECT). The results of studies comparing the efficacy of rTMS and ECT are mixed and, therefore, comparison of these two therapies needs to be further explored. Forty-two patients aged between 18 and 65 yr, referred to ECT due to unipolar non-psychotic depression refractoriness entered the trial. They were randomly assigned to receive either rTMS or ECT. Depressive symptom changes were blindly measured by Hamilton Depression Rating Scale, Visual Analogue Scale and Clinical Global Impression at baseline, after 2 wk and after 4 wk of treatment. There was no difference in the antidepressant efficacy of ECT and rTMS. Response rates were relatively low in both groups (40% and 50% respectively), with no significant difference between them (p=0.55). Remission rates were also low for both groups (20% and 10% respectively), also with no significant difference (p=0.631). There was no significant difference in the neuropsychological test performance after either one of these therapies. Both treatments were associated with a degree of improvement in refractory depression and therefore add to the literature that rTMS can be an effective option to ECT as it is a less costly treatment and is not associated with anaesthetic and other ECT risks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
