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 swabs was labelled to your date and time of range also the systematic section of works of one’s participant. The participants was assigned another personality count. The newest collected samples have been instantaneously transmitted for the microbiology research and was cultured into the Nutrient agar typical and you can incubated having twenty four h in the 37 °C . Identification of the isolates try done-by Gram stain and you may important biochemical evaluation (Catalase try, Coagulase shot, Indole try, Methyl purple decide to try, Voges-Proskauer attempt, Citrate shot, Oxidase make sure Urease shot).


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).

All 1st swab trials obtained from this new 62 stethoscopes showed microbial gains. The fresh new examples obtained from 35 stethoscope bells and you can 31 stethoscope diaphragms presented mixed development. With the stethoscope bells, 96 bacteria had been remote which composed of eight various other genera. Outside of the 96 organisms isolated out of stethoscope bells, 80 were Gram-positive cocci (GPC) and you will sixteen were Gram-bad bacilli (GNB). Among 96 isolates, twenty five was in fact probably pathogenic while the others have been skin commensals. Towards stethoscope diaphragm, a total of 92 bacteria had been remote comprising eight other genera. From the 96 organisms isolated from stethoscope diaphragm, 79 was in fact GPC and you can thirteen was basically GNB. Among 92 isolates, twenty-two was possibly pathogenic as well as the other countries in the isolates was indeed facial skin commensals. Probably pathogenic isolates was indeed S. aureus, Acinetobacter spp. and you will K. pneumoniae.

Shortly after cleanup having a beer-dependent disinfectant, K. pneumoniae was separated from one of the stethoscope bells included in a keen ICU, during the brand new diaphragm of the stethoscope included in an enthusiastic ICU, a couple strains out of K. pneumoniae and one Coagulase-negative staphylococcus (CoNS) was remote and two strains regarding Drawbacks had been remote regarding stethoscopes from medical people.

Of 62 stethoscopes, 25 had possibly pathogenic microbial growth in advance of cleaning stethoscopes having alcohol-created disinfectant. Although not, immediately following cleaning the stethoscopes, just two had pathogenic development of isolates. 01.
