Após a desinfecção dos estetoscópios com álcool gel, foi constatada uma redução de 71,44% da contaminação geral por microrganismos.…”

“…A ferramenta utilizada para análise foi o software Epiinfo na versão 7. [1][2][3][4] Estetoscópios contaminados já foram implicados na transmissão de bactérias patogênicas no ambiente hospitalar. [5][6][7] Apesar de simples, a frequente deficiência na limpeza dos estetoscópios pode comprometera segurança dos pacientes e do próprio profissional de saúde.…”

“…Apart from normal skin flora, most stethoscopes harbor potential pathogens like Staphylococcus aureus (methicillin-sensitive or -resistant), Klebsiella , Acinetobacter, Enterococcus and extended-spectrum β-lactamase-producing Enterobacteriaceae [4–8]. Contamination of stethoscopes with methicillin-resistant Staphylococcus aureus (MRSA) ranges from 0% - 32% [9].…”

“…These potentially pathogenic organisms can survive on inanimate surfaces for days to months [10]. When stethoscopes are not decontaminated prior to use, they may act as vector [4–6, 8] leading to transmission of organisms from one patient to another.…”

BackgroundIn developing countries like Nepal, 90% ethanol is cheap and is available in most hospitals. The unavailability of isopropyl alcohol (IPA) in these settings led us to compare the efficacy between 90% ethanol and isopropyl alcohol pads in reducing the bacterial contamination of diaphragm of stethoscope.MethodsA randomized blinded experimental study was carried out to determine the difference between cleaning stethoscopes with 90% ethanol and IPA. Cultures of diaphragm were taken before and after cleaning with one of the cleaning agent. Colony forming units (CFU) count and organism identification was done by a blinded investigator. CFU before and after cleaning were compared using Wilcoxon signed–rank test. Mann Whitney U test was used to compare the decrease in CFU count between the cleaning agents.ResultsAbout 30% of the stethoscopes harbored potential pathogens. Significant reduction in CFU was observed with both IPA (Wilcoxon signed–rank test, P value <0.001) and 90% ethanol (Wilcoxon signed–rank test, P value <0.001). Comparing median decrease in CFU between cleaning with IPA and with 90% ethanol, no significant difference was found (Mann Whitney U test; U = 1357, P value >0.05).ConclusionsBoth 90% ethanol and IPA are equally effective in decontaminating the diaphragm of stethoscope. Selection of agent should be done on the basis of cost and availability.

Patient safety: This is public health

Avoidable patient harm is a major public health concern, and may already have surpassed heart disease as the leading cause of death in the United States. While the public health community has contributed much to one aspect of patient harm prevention, infection control, the tools and techniques of public health have far more to offer to the emerging field of patient safety science. Patient safety practice has become increasingly professionalized in recent years, but specialist degree programs in the field remain scarce. Healthcare organizations should consider graduate training in public health as an avenue for investing in the professional development of patient safety practitioners, and schools and programs of public health should support further research and teaching to support patient safety improvement.
