During this unprecedented COVID 19 pandemic, healthcare workers are one of the most vulnerable high-risk groups who have been contracting the virus, second only to the seniors living in long-term care facilities.
In this background, I looked at the existing evidence about one crucial aspect in the prevention and control of spreading the virus: healthcare workers’ hand hygiene.
During my exploration, I found a systematic review of systematic reviews published in 2018.
A systematic review of systematic reviews – 2018
As anyone can guess, there has been a large number of research available in the world for someone to conduct a systematic review of systematic reviews.
This review has looked at 19 systematic reviews published between 2001 to 2017. Of these, 13 reviews included hospital-based primary studies. In addition to the hospitals, the rest has looked at studies from long-term and other care facilities. Before going further, I would like to highlight that only study, according to their review criteria, had low-risk of bias.
They have found that;
- the interventions that targeted social influence, attitudes, self-efficacy, and intention were associated with greater effectiveness.
- no clear association between the delivery method of the intervention and its effectiveness.
It seems clear that the interventions work. However, there are several caveats; no adequate evidence about the nature of the content, delivery method, and monitoring strategies.
