In France, the widely used standard for prevention of infections is through the use of probe covers and LLD of the ultrasound transducer by disinfectant wipes. We performed an in silico simulation based on a systematic review to estimate the number of patients infected after endorectal or vaginal ultrasonography examination using LLD for probes.<\/jats:p><\/jats:sec><jats:sec id=\"S0899823X00193626_abs2\"><jats:title>Study design.<\/jats:title><jats:p>We performed a stochastic Monte Carlo computer simulation to produce hypothetical cohorts for a population of 4 million annual ultrasound examinations performed in France, and we estimated the number of infected patients for human immunodeficiency virus (HIV), herpes simplex virus, hepatitis B virus, hepatitis C virus, human papilloma virus, cytomegalovirus, and <jats:italic>Chlamydia trachomatis<\/jats:italic>. Modeling parameters were estimated by meta-analysis when possible.<\/jats:p><\/jats:sec><jats:sec id=\"S0899823X00193626_abs3\"><jats:title>Results.<\/jats:title><jats:p>The probability of infection from a contaminated probe ranged from 1% to 6%, depending on the pathogen. For cases of HIV infection, this would result in approximately 60 infected patients per year. For other common viral infections, the number of new cases ranged from 1,600 to 15,000 per year that could be attributable directly to ultrasound and LLD procedures.<\/jats:p><\/jats:sec><jats:sec id=\"S0899823X00193626_abs4\"><jats:title>Conclusions.<\/jats:title><jats:p>Our simulation results showed that, despite cumulative use of probe cover and LLD, there were still some cases of de novo infection that may be attributable to ultrasound procedures. These cases are preventable by reviewing the currently used LLD and\/or upgrading LLD to high-level disinfection, as recommended by the US Centers for Disease Control and Prevention.<\/jats:p><\/jats:sec>","DOI":"10.1086\/678604","type":"journal-article","created":{"date-parts":[[2014,11,5]],"date-time":"2014-11-05T19:28:53Z","timestamp":1415215733000},"page":"1497-1504","source":"Crossref","is-referenced-by-count":14,"title":["Impact
