CHICAGO (Reuters), Apr 18 - Hand washing is something most people learned about as children, but a British study finds that health workers are not faithful about washing their hands and few strategies to improve hygiene have worked.
Infections spread by health workers are a major cause of illness and death, and simple hand washing is shown to be one of the best ways to prevent it.
In Britain, 10% of patients develop healthcare-associated infections, which kill 5,000 people each year at a cost of $1.86 billion a year, the researchers said.
In the U.S., health workers' dirty hands infect about 5% of patients at a cost of $4.5 billion a year, they said.
A team of researchers led by Dr. Dinah Gould of the School of Nursing and Midwifery at City University in London performed a systematic review to determine whether strategies to improve hand hygiene are effective.
The researchers, whose study was published in this week's Cochrane Library Newsletter, found only two trials that were even worth consideration and both were of poor quality.
Based on those, they concluded that a single teaching session or seminar was not likely to affect hand-washing behavior, even in the short term.
"We desperately need some good research that will begin to show which interventions can bring about change in people's behavior," Gould said in a statement.
"In addition to preventing unnecessary spread of disease, good hand hygiene is highly desirable on aesthetic grounds alone," she said.
"It forms an important indicator of the quality of healthcare and should continue to be promoted in all clinical settings," she added.

![Overview of the study design. (A) The fully automated deep learning framework was developed to estimate body composition (BC) (defined as subcutaneous adipose tissue [SAT] in liters; visceral adipose tissue [VAT] in liters; skeletal muscle [SM] in liters; SM fat fraction [SMFF] as a percentage; and intramuscular adipose tissue [IMAT] in deciliters) from MRI. The fully automated framework comprised one model (model 1) to quantify different BC measures (SAT, VAT, SM, SMFF, and IMAT) as three-dimensional (3D) measures from whole-body MRI scans. The second model (model 2) was trained to identify standardized anatomic landmarks along the craniocaudal body axis (z coordinate field), which allowed for subdividing the whole-body measures into different subregions typically examined on clinical routine MRI scans (chest, abdomen, and pelvis). (B) BC was quantified from whole-body MRI in over 66,000 individuals from two large population-based cohort studies, the UK Biobank (UKB) (36,317 individuals) and the German National Cohort (NAKO) (30,291 individuals). Bar graphs show age distribution by sex and cohort. BMI = body mass index. (C) After the performance assessment of the fully automated framework, the change in BC measures, distributions, and profiles across age decades were investigated. Age-, sex-, and height-adjusted body composition reference curves were calculated and made publicly available in a web-based z-score calculator (https://circ-ml.github.io).](https://img.auntminnieeurope.com/mindful/smg/workspaces/default/uploads/2026/05/body-comp.XgAjTfPj1W.jpg?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
