Stethoscopes Used In The ICU are Loaded With Harmful Bacteria

Stethoscopes used in an intensive care unit (ICU) can have bacteria on them, including those that are associated with hospital-acquired infections (HAIs), finds a recent research.

Imperative to put in place control guidelines and educate clinicians on the outcomes of not ensuring safety.

Physicians' Stethoscopes are Highly Contaminated, Says Study
The level of bacterial contamination on physicians' hands and stethoscopes following a single physical examination was assessed in a study.

‘Stethoscopes can be cleaned using a combination of 90% ethanol, isopropyl alcohol (IPA), and chlorhexidine. It will help reduce the bacterial contamination of the stethoscope.’

Standard cleaning methods do not eliminate the problems. Practitioner stethoscopes are contaminated by a plethora of bacteria, including organisms that may be associated with nosocomial infections.

The researchers found that all stethoscopes used in the ICU were significantly contaminated with a variety of pathogens. The highest bacterial contamination levels were found on practitioner stethoscopes,followed by patient-room stethoscopes. Bacterial contamination levels on clean stethoscopes and background controls were indistinguishable from each other.

Speaking about this, Padma Shri Awardee, Dr. KK Aggarwal, President, HCFI, the instrument, both patients and healthcare workers may not take it as a transmitter of bloodborne pathogens or a vector of infection. However, the truth is far from this. Some of these pathogens include Staphylococcus aureus, Pseudomonas aeruginosa, Clostridium difficile, and vancomycin-resistant enterococci.

Artificial Intelligence to Predict the Presence of <i>S. epidermidis</i>

Artificial Intelligence to Predict the Presence of S. epidermidis
Staphylococcus epidermidis causes nosocomial infections in surgical procedures and indwell devices, which presence can be predicted using machine learning devices.

These are responsible for many diseases such as pneumonia, urinary tract infections (UTIs), and skin infections, some of which can be life-threatening. Patients and at times, even hospital staff, fail to follow certain basic hygiene protocols which can go a long way in preventing these infections. This is further exacerbated by the fact that there is no specific documentation of HAI incidence.

Studies have also concluded that the diaphragm of the stethoscope is more contaminated than other regions of the hand, including the skin around the base of the thumb and little finger, or the back of the hand.

Hospital-Acquired Infections can be Predicted by Machine Learning
Finnish researchers have used Machine Learning (ML) to predict the presence of nosocomial or hospital-acquired infections caused by Staphylococcus epidermidis.

Adding further, Dr. Aggarwal said that They should conduct a cleanliness check between each patient encounter. Cleaning hands and ensuring other forms of hygiene is also an important.

Some tips from HCFI

One Of The Deadliest Hospital-Acquired Infections Is Preventable
Health care providers can take steps to curb complications of mechanical ventilation, or ventilator associated events to reduce hospital acquired infection.

Stethoscopes can be cleaned using a combination of 90% ethanol, isopropyl alcohol (IPA), and chlorhexidine. It will help in reducing the bacterial contamination of diaphragm of the stethoscope.
