29 November 2018 ICT Deadly Pathogens are Great at Hide-n-Seek But SteraMist™ Always Finds Them The only EPA registered solution and equipment combination for hospital disinfecting that goes above, beyond, under and around to fnd them and reduce the spread of deadly pathogens. Easily Implement SteraMist™ Into Your Protocols Today! 800.525.1698 | isolated a total of 9,521 bacterial CFUs from 192 samples in phase I from the fl oor samples and 9971cfu from 192 samples in phase II. From 96 air samples in each phase, a mean of 262 cfu/m3 in phase I and 220cfu/m3 in phase II were isolated. The difference between the two phases was statistically not signifi cant (p value > 0.05 for both). The researchers reported that fl oor and air colony counts showed no signifi cant difference in the two phases with and without protective footwear and concluded that protective footwear had no significant impact on bacterial contamination of fl oors. In a more recent study, 40 disposable medical shoe covers were briefl y exposed to the surgical fl oor and were found by Galvin, et al. (2016) to be contaminated by a large number of bacteria. This study also demonstrated live bacteria, including pathogens attached to contaminated shoe covers, can be subsequently transferred to surgical bedsheets. As Galvin, et al. (2016) note, "The hospital fl oors in the day surgery unit were cleaned daily and appeared clean by visual observation. Nevertheless, the shoe covers worn for 5 minutes picked up substantial amounts of live bacteria. This highlights the ability of microorganisms to be present in seemingly clean environments. This study also demonstrated that the live bacteria attached to contaminated disposable medical shoe covers can be subsequently transferred to bedsheets. This has the implication of all patients being equally susceptible to infection regardless of their waiting time prior to surgery, especially if they get into and out of their bed on multiple occasions. The transmission of bacteria from the day surgery fl oor to the bedsheet opens up the possibility of a patient developing an SSI." The researchers add, "We suggest an infection control policy should be considered to prevent patients returning to their bed with contaminated disposable shoe covers because this simple measure may reduce surgical bed contamination and the number of SSIs and their associated detrimental impact." Ali, et al. (2014) sought to examine the role of using shoe covers by medical staff and visitors on infection rates, mortality and length of stay in the ICU. The researchers measured the rates of infection (by checking patients for common ICU pathogens), mortality and length of stay of patients admitted in MICU and SICU for three consecutive months in the spring. Use of shoe covers was abandoned during this period. The same parameters were measured for the patients admitted for another three-month period in the summer, the period during which shoe covers were strictly used by all the staff members and visitors. The data was then analyzed and compared. A total of 1,151 patients were studied in the six-month period. Among the two groups of patients, managed with and without using shoe covers in the ICU, statistically signifi cant decrease was seen in terms of length of ICU stay in patients managed in duration of shoe covers. However, the time period in which shoe covers were used the infections with three common ICU pathogens — MRSA, VRE and Acinetobacter — were statistically signifi cant more than the periods in which shoe covers were not used. There was no significant difference in mortality for both groups. Mahida and Boswell (2016) also considered the impact of non-slip socks. As they explain, "Non-slip socks are single-use medical device items but the frequency with which they should be changed is unclear. Hence patients may wear these socks for a short period of hours or possibly several days. In addition, investigators noted that patients not only use them to walk to various parts of the hospital during the inpatient journey, including toilets, radiology departments, coffee shops, restaurants, but also wear them in bed. These socks are made of cotton and polyester, terrycloth lined, with treads added to improve underfoot traction."
