Those infections related to health care (IRAs) are one of the main problems of the health system because they cause an increase in health spending and detract material and human resources, and even result from a direct mortality. One of the causes of IRAs is pollution in the patient environment, where the surfaces are germfree very soon after cleaning, becoming a vector of transmission by direct contact. Nanobiomatters BactiBlock® S.L. uses nanotechnology to incorporate silver ions in a wide variety of products in order to reduce the growth of bacteria and fungi on the surfaces where they are applied. Doubleblind pilot study conducted at the Hospital Nisa 9 de Octubre in Valencia, where the effect of the coating for metals BactiBlock® in reducing bacterial contamination in a medical environment was investigated. BactiBlock® was applied to the doorknobs of 8 rooms and 2 randomly chosen priests cars, leaving as a control other 8 rooms and 2 priests not treated. Microbiological tests are performed using contact plates before treatment and weekly thereafter for a period of nine weeks. Results are expressed as the mean count of colony forming units per plate (CFU / plate).
Results
Initial checks showed no significant differences between the two groups (treated and untreated) before starting the test (p> 0.05). The mean CFU / plate was 84.53 for the knobs and 59.83 for the cars.
Conclusions
The results show that the application of the coating for metals BactiBlock® allows control pollution of the surfaces of the patient’s environment, even in the most septic ones, maintaining a state of optimal aseptic for 9 weeks (<25 CFU / plate required level in area high risk).
