Doctors’ Cell Phones Are Contaminating Hospitals by Annie Charron

Today we have another guest undergraduate student post, originally submitted as a class assignment for Communicating Science (CCOM 314).

With support from Diane Dechief, Faculty Lecturer at the McGill Writing Centre, we will be sharing more noteworthy student writing right here on The Turret.

Annie chose to write a Trilobite article that provides knowledge on the health consequences of the use of cell phones by doctors.

Doctors’ Cell Phones Are Contaminating Hospitals

Your mobile phone carries the dirty fragments of germs. Thousands of microscopic bacteria bugs are crawling on it. The residue of greasy food is smudged on the screen. The remnants touched on public door handles have engulfed the surface of the phone.

Mobile phones are your hands’ partner in crime: you can wash your hands to eradicate germs and prevent the spread of germs, but you can’t wash the cell phone – at least not with soap. Without proper cleaning, germs are like glitter, they will never go away. Healthcare workers who bring mobile phones to work interfere with infection controls in hospitals.

Healthcare workers cell phones are a magnet for bacteria and harmful chemicals, which could decrease patients’ recovery. Hospitals should be the most sterile places in the world. But our tiny gadgets may ruin this. At any rate, there should be major shame towards the television series Grey’s Anatomy, where the characters are constantly using their mobile devices during patient care without washing their hands.

In a study published by Excellent Publishers in 2017, Ganapathy Shakthivel and his colleagues, working in the department of microbiology at Tirunelveli Medical College in India, examined 50 randomly selected healthcare workers at a specialized care hospital. They investigated how the bacterial contamination of cell phones poses a threat to infections. They then assessed whether contamination could be cleaned simply with 70% rubbing alcohol.

The study lasted for two months and included mobile phones belonging to doctors, nurses, laboratory technicians, nursing assistants and hospital workers. Each worker first filled out a questionnaire that asked questions about the prevalence of phone usage between patient consultations and if workers washed their hands in between use or followed a strict sterile routine. Following this, each mobile phone was swabbed twice. The first swab took place before the decontamination procedure, the second swab occurred after the phone was thoroughly cleaned with the rubbing alcohol for 5 to 7 minutes.

The study revealed that of the 50 mobile phones in the study, 90% were found to be carrying multiple microorganism bacteria such as E. coli, which is very likely to cause infections. The decontamination results revealed that rubbing alcohol proves effective. The majority of the phones (78%) showed no bacterial growth after decontamination and 12% showed decreased bacterial growth. Another study led by Usha Arora (2009), showed a higher decontamination efficacy of approximately 98% with the 70% rubbing alcohol, compared to Ganapathy Shakthivel’s (2017) results of 86.6%.

Ganapathy Shakthivel (2017) states that the use of cell phones in India accounts for more than 88% of all users in Intensive Care Units and Operation theaters. And if a cell phone is not routinely cleaned in hospitals it becomes “a reservoir of infection.” Phones are a vehicle for the transmission of infection, to both patients and the community. The questionnaire revealed that only 12% of the healthcare workers made a habit of washing their hands before attending to a patient. That being said, “nearly 52% of the workers agreed that mobile phones may act a vector for spread of nosocomial (a disease originating in a hospital) infections.”

Preventative methods for eliminating the spread of infection via cell phones, include training other individuals (children, colleagues) not to touch phones other than their own. Some hospitals have banned or eliminated the use of cell phones during working hours. This may be hard to accomplish, considering you touch your phone on average 2,617 times a day. The most important strategy is simply to clean the device with rubbing alcohol before, during and after work – this regular routine will significantly reduce infections in hospitals.
