In light of the recent coronavirus outbreak, the Centers for Disease Control and Prevention (CDC) urges the public to thoroughly and frequently wash their hands with soap and water, highlighting the fact that proper hand hygiene is a tried and tested practice of preventing the spread of infection. However, what you might not know is that among all types of healthcare providers, physicians are the least likely to wash their hands while caring for their patients.
This is a complete step back from what Hungarian physician Ignaz Semmelweis first observed back in 1846. Semmelweis analyzed two maternity wards in a hospital where he worked and discovered that death rates saw a significant drop when physicians, who were working with cadavers or assisting in births, washed their hands regularly. Unfortunately, doctors at the time did not take the findings kindly, angry for being blamed for the deaths of their patients.
Even today, it can still be difficult to convince some healthcare professionals to regularly wash their hands in between patient interactions. According to a study published in the journal Annals of Internal Medicine, only about 57 percent of 163 doctors washed their hands between patients. Lead researcher Didier Pittet observed that doctors with busy workloads were even less likely to wash their hands. However, if they thought that they were being observed, the doctors were more likely to follow proper hand hygiene.
Another study, presented at the Association for Professionals in Infection Control and Epidemiology conference, attributed hand hygiene habits to the Hawthorne effect. The researchers found that hygiene compliance differed significantly depending on whether or not the health professionals knew they were being evaluated.
Negative effects of poor hand hygiene
Poor adherence to hand hygiene has been a longstanding issue. The CDC reports that healthcare providers only wash their hands less than half the time that they should. The World Health Organization (WHO) has also observed an average adherence of as low as 40 percent.
Hand-washing for healthcare practitioners is important to avoid the spread of healthcare-associated infections (HAI) that is commonly linked to poor hand hygiene. Microbes that can spread by hand contact include Staphylococcus aureus (including MRSA), Streptococcus pyogenes (Group A Strep), vancomycin-resistant Enterococcus (VRE), Klebsiella, Enterobacter, Pseudomonas, Clostridium difficile, Candida, Rotavirus, Adenovirus, Hepatitis A virus and Norovirus.
According to the CDC, about one in 31 hospital patients has at least one healthcare-associated infection on any given day. In 2015, it was estimated that there were 687,000 HAIs in US acute care hospitals – and about 72,000 of these patients died during their hospitalizations.
