Professor Rhonda Griffiths, from the UWS School of Nursing, says the research arose from an inquiry by community health nurses who needed evidence to support a common practice and belief that showering patients with leg ulcers was both safe and effective.
"In response we searched for studies done by others on cleansing wounds using the shower, however we were unable to locate any evidence to support the practice," Professor Griffiths says.
"So we conducted a six-week double blind, randomised controlled trial in South Western Sydney involving 35 patients with 49 wounds.
"None of the wounds cleansed with tap water showed signs of infection and we found no sign that the healing rate was slow.
"We came to the conclusion that where there is access to tap water that is suitable for drinking, it may be as effective – and certainly more cost effective – than other methods," Professor Griffiths says.
"Although the results need to be confirmed by a larger study, we believe that with this simple, yet robust, trial we have uncovered evidence that could save nurses' time, reduce costs and also make it easier to involve patients in their own self-care of wounds.
"This research shows how a clinical problem identified by working nurses, can promote research to then go on to inform existing practice," she says.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
