Insufficient training for construction crews poses risks in health care settings

Researchers at Washington State University and Clemson University have found that invasive fungal diseases in health care facilities often occur after construction and renovation activities.


Researchers at Washington State University, Pullman, Washington, and Clemson University, Clemson, South Carolina, have found that insufficient training for construction workers in hospital settings may be contributing to fungal disease outbreaks that endanger patients.

While training done for construction crews working in a healthcare environment is critically important, several studies have reported that invasive fungal diseases in health care facilities often occur after construction and renovation activities.

In the U.S. there have been nearly 50 fungal outbreaks associated with construction between 1980 and 2015, resulting in infections and more than 120 patient deaths. Infections from mold are dangerous, particularly, for people who are already sick and in the hospital.

Meanwhile, a recent industry survey found that 49 percent of all health care expenditures in 2017 went to facility renovation to meet rising demand for inpatient care. According to Tommy Tafazzoli, assistant professor in the School of Design and Construction at Washington State University, the dust generated during construction can lead to the spread of contaminants, including pathogenic fungi spores, into nearby buildings.

“A lot of these renovations are relevant to some type of construction activity,” Tafazzoli said. “Renovation, most of the time, means that the healthcare unit is active and that patients are there.”

As part of the study, Tafazzoli surveyed 129 people working in 15 leading healthcare construction contractors in the U.S. to determine their level of dust contamination training.  The researchers found a lack of standardized training, that the trainings were mostly tailored for upper management and that contractor and sub-contractor construction crews received the least amount of training.

“If you’re doing construction in a cardiac care unit it’s a lot more sensitive than, for example, doing construction activity in a courtyard of a hospital,” Tafazzoli said.

Tafazzoli would like to see uniform regulations for construction companies that are contracted in healthcare facilities. The researchers are now working to develop detailed training guidelines for construction crews.
