In order to assess the knowledge and cleaning practices regarding the disinfection of stethoscopes, the healthcare personnel were administered a questionnaire at the same visit while collecting samples from their stethoscopes. 0D and S0B, respectively) were collected using sterile swabs moistened with sterile saline from one half of the stethoscope to document the baseline microbial load on the diaphragm. The stethoscope was then cleaned by alcohol-based disinfectant (Sterillium), commonly used as hand disinfectant in the hospitals. After cleaning and allowing the stethoscope to dry for 30 s, two samples were further collected using sterile swabs (labelled S1D and S1B) from the other half of the stethoscope’s diaphragm and bell. This division of the stethoscope into two parts was done to obviate the effect of physical removal of microbes by the first swab, thereby affecting the assessment of reduction in microbial load after cleaning, if any. In order to eliminate confusion and maintain uniformity, one of the researchers collected the samples from the stethoscopes whereas another researcher cleaned the stethoscope and administered the questionnaire.

This finding is statistically significant with P < 0

Both the swabs have been labelled to your date and time out of collection in addition to the scientific area of performs of the fellow member. The participants was tasked yet another character amount. The gathered trials was quickly transported into the microbiology laboratory and had been cultured into Nutrient agar lovoo slevovГЅ kГіd typical and you can incubated getting twenty-four h during the 37 °C . Identity of one’s isolates try accomplished by Gram spot and you may important biochemical screening (Catalase test, Coagulase attempt, Indole take to, Methyl red-colored attempt, Voges-Proskauer decide to try, Citrate attempt, Oxidase ensure that you Urease decide to try).


Out of 62 participants, 87% believed that the stethoscope is a potential source of carrying infections from one individual to other. Thirty-three individuals (%) had never cleaned their stethoscopes, 15 (24.2%) cleaned their stethoscopes > 8 weeks previously, two (3.2%) cleaned their stethoscopes 5–8 weeks previously, six (9.6%) cleaned their stethoscopes 1–4 weeks previously and only six (9.6%) individuals had cleaned their stethoscopes < 1 week ago. None of the participants cleaned their stethoscopes after seeing each patient. Among the individuals who cleaned their stethoscopes, only one participant cleaned his/her stethoscope daily. Among the individuals who cleaned their stethoscopes, the majority (86.2%, participants) used alcohol-based disinfectant (Sterillium), followed by a plain cloth (10.3%, 3/29 participants) and soap and water (3.5%, 1/29 participants).

Most of the 1st swab samples obtained from brand new 62 stethoscopes showed bacterial progress. This new examples taken from thirty five stethoscope bells and you will 31 stethoscope diaphragms showed combined increases. Into stethoscope bells, 96 organisms was isolated and therefore comprised of eight some other genera. Out of the 96 organisms isolated off stethoscope bells, 80 were Gram-positive cocci (GPC) and you will sixteen was Gram-bad bacilli (GNB). One of several 96 isolates, twenty five have been possibly pathogenic therefore the others had been facial skin commensals. To your stethoscope diaphragm, a total of ninety five bacteria was indeed separated spanning eight various other genera. From the 96 organisms separated out-of stethoscope diaphragm, 79 were GPC and you can 13 was in fact GNB. One of several ninety five isolates, 22 was probably pathogenic together with remaining isolates had been epidermis commensals. Possibly pathogenic isolates have been S. aureus, Acinetobacter spp. and you will K. pneumoniae.

Immediately after cleaning which have a beer-mainly based disinfectant, K. pneumoniae was remote from one of one’s stethoscope bells found in an enthusiastic ICU, while on the fresh diaphragm of stethoscope included in an enthusiastic ICU, several stresses from K. pneumoniae and one Coagulase-bad staphylococcus (CoNS) was basically isolated as well as 2 stresses of Downsides had been isolated throughout the stethoscopes from scientific children.

Away from 62 stethoscopes, twenty five got potentially pathogenic bacterial growth before cleanup stethoscopes having alcoholic beverages-created disinfectant. However, once cleansing the stethoscopes, only a couple got pathogenic growth of isolates. 01.
