Researchers Fault Medical Practitioners who Treat Patients while Sick


A lot of medical practitioners usually risk transmitting respiratory viruses to patients and co-workers by attending to patients even after knowing they have the symptoms, a recent study published in the journal infection Control & Hospital Epidemiology has found.

The study stated that 95 per cent of people working in healthcare settings have worked while sick, most often because the symptoms were mild or illness started during their workday.

Common viral respiratory diseases (CVRD) are illnesses caused by a variety of viruses that have similar traits and affect the upper respiratory tract. Example of CVRD include fever and one or more cold symptoms such as chills, headache, body ache, weakness, and loss of appetite.

The viruses are spread directly by droplets coughed or sneezed into the air which are then inhaled, or indirectly by contaminated hands, handkerchiefs, toys, etc. which come in contact with the nose or eyes.

Brenda Coleman, PhD, clinical scientist in the Infectious Disease Epidemiology Research Unit at Mount Sinai Hospital, Toronto, and lead author of the study explained that “We found that physicians and people working in areas that required the most intensive contact with patients were less likely than other workers to stay home or to leave work if symptoms progressed after the start of the day”.

Coleman added that managers and senior staff need to both model and insist on workers staying home when symptomatic as it protects both patients and co-workers from infections.

Findings from the Centres for Disease Control and Prevention recommends that healthcare workers with fever and respiratory symptoms consider temporary reassignment or exclusion from work for while symptomatic, but working with symptoms of an acute respiratory viral illnesses is common, with as many as 92 per cent of healthcare workers reporting to work while symptomatic.

According to the findings from the journal for the Society for Healthcare Epidemiology of America, the researchers conducted a four-season prospective cohort study of influenza and other respiratory illnesses in nine Canadian hospitals in Toronto, Hamilton, and Halifax.

Medical practitioners in acute care hospitals who worked more than 20 hours a week were asked to complete daily online illness diaries whenever they developed symptoms.

Illness diaries collected information about symptoms, possible exposure, and attendance at work, reason for work or absence, and medical consultations.

A total of 10,156 illness diaries were completed by 2,728 participants. Diaries of participants that were not scheduled to work were excluded, leaving 5,281 remaining diaries for analysis.

Analysis of the diaries found that 69 per cent of participants said that they worked during an illness because they had mild symptoms and felt well enough to work, 11 percent said they had things to do at work, 8 percent felt obligated to work, and 3 percent stated that they could not afford to stay home.

Half of the participants reported episodes of acute respiratory viral illness during each influenza season, with 95 percent of those who reported an acute respiratory viral illness working one or more days of their illness. Seventy-nine percent said they were entitled to paid sick leave.

These findings suggested the need to educate healthcare workers, managers, workplace health and safety and infection control staff, and administrators about the risk of transmission associated with respiratory viral infection, to clarify what symptoms require exclusion from work, and to develop and implement policies for working while symptomatic, Coleman said.

“Though the study was conducted in Canada, researchers believe the results also apply to most countries in the world, since most hospitals follow similar recommendations to prevent the spread of disease, including standard, droplet and contact precautions as well as vaccination requirements”. Coleman said.
