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.

Communicating Science: Profile of Sierra Clark by Audrey Carleton

Today we have a guest 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.

Audrey Carleton chose to write a profile on Sierra Clark, a graduate student supervised by Dr. Jill Baumgartner in the Institute for Health and Social Policy.

Headline: Sierra Clark on indoor air pollution and academic uncertainty

Subhead: McGill Master’s student tests lifesaving interventions for Tibetan Plateau residents

By: Audrey Carleton

Date: December 1, 2017

Sierra Clark has been reading National Geographic for as long as she can remember. Even before she learned to read, she would eagerly flip through the magazine’s glossy pages to admire its photos. From this young age, she had her sights set on someday working for the publication as an archaeologist.

In the twenty years that followed, Clark had a few changes of heart. When she began her undergraduate degree at McGill University in 2011, she was enrolled with a major in Anthropology. But after sitting through a few convoluted lectures in an introductory anthropology course, she realized the program wasn’t the right fit for her. One meeting with an academic advisor later, she settled on a major in Geography, and swiftly fell in love with it. Upon graduating in 2015, she swiftly enrolled in a Master’s Program in Epidemiology at McGill, which she is completing now. All the while, Clark continued to read National Geographic religiously.

Presenting with style: Mixing the arts of storytelling & teaching

In 3-minute thesis competitions, participants explain their research projects (the why, the how, and the implications for the real world) to non-experts in three minutes or less. The speaker of the best presentation wins. Great presenters will:

  • speak clearly and unhurriedly;
  • vary their pitch;
  • incorporate a story, include a metaphor from everyday life, and/or strike an emotional cord in the listener;
  • mention unexpected/interesting facts about their topics (e.g., Silver changes the color of your tongue to blue.); and
  • provide tangible examples.

The “CHEE 687: Research Skills and Ethics” class watched some 3-minute thesis competitors in action to prepare for their own presentations. My favourite 3-minute thesis talk was from Balarka Banerjee.showing lung capacityWe also discussed elements of a good PowerPoint presentation, which:

  • has minimal content on each slide;
  • contains descriptive/specific headings (rather than general and predictable headings like Introduction, Background, Results, Conclusions);
  • engages the audience at the beginning of the presentation with news headlines, statistics, or a story;
  • includes consistent formatting throughout;
  • utilizes a light background with dark text;
  • employs graphics to explain phenomena, processes, and/or concepts; and
  • includes citations for any images used (when not your own) on the slide itself.

This is the sixth in a series of weekly posts about topics relating to research skills and ethics. I will be taking a temporary hiatus from blogging and will resume writing this series later on in 2016. Happy holidays!

Three minutes to explain yourself

Can you explain your research activities or thesis in 3 minutes to someone outside your field?  Jinna Kim in University Affairs reports that many universities are holding prize-winning competitions that require graduate student participants to communicate their work to judges and an audience in just 3 minutes.  The idea is to teach students how to promote themselves and their research.

McGill University has an annual event called, “3 Minutes to Change the World” that provides a non-competitive opportunity for graduate students to present their research to a general audience.  Below is an example of a presentation from this event:
