To the Editor—Haun et alReference Haun, Hooper-Lane and Safdar 1 wrote a review of the literature regarding 2 fomites found in hospitals: devices and attire. This article raises the importance of hygiene in inpatient units to prevent increasingly multidrug-resistant bacteria in hospitals all over the world, and this issue is particularly relevant to our practice. We would like to contribute our experience in a French military hospital to their findings.

In France, we have seen an increase of patients infected or colonized with MRB. For example, Arnaud et alReference Arnaud, Maugat, Jarlier and Astagneau 2 showed that the incidence of extended β-lactamase–positive Enterobacteriaceae infections in French hospitals increased by 73% from 0.35 to 0.60 per 1,000 patient days (P<.001) from 2009 to 2013. Consequently, the risk of cross infection increases.Reference Cardoso, Almeida and Carratalà 3 In this context, we wanted to improve infection prevention in our hospital this past year. Because the indicator of consumption of hydro-alcoholic solution, ICSHA-2 (indicateur de consommation de solutions hydro-alcooliques number 2) is at its highest in our hospital, we focused our attention on 2 other fomites (ie, like Haun et al): devices and attire.Reference Huskins, Huckabee and O’Grady 4

We first studied the bacterial contamination of mobile phones. We obtained 80 samples from 40 phones from 40 people of all healthcare occupations: nurses, doctors, nursing aides and hospital service agents. Overall, 16 mobile phones (40%) were contaminated (ie, >50 colony forming units/25 cm2). Indicator bacteria were found on 3 phones: Staphylococcus aureus (n=2) and Escherichia coli (n=1). Mobile phones of doctors and nurses were contaminated more often than those of other healthcare workers: 65% versus 35%, respectively (P=.01).

In a second investigation, we controlled the implementation of standard precautionsReference Tschudin-Sutter, Sepulcri, Dangel, Schuhmacher and Widmer 5 when a patient was hospitalized for pneumonia because of K. pneumoniae OXA48. We recognized that doctors did not change professional attire every day. Thus, we created a new hospital hygiene indicator: index of change of attire (ICA).

The goal is that each caregiver changes attire every day. This ICA is calculated using 2 variables. The first, referred to as X, is the number of outfits washed each month in the hospital. We were able to measure this variable with the assistance of the laundry service. The second variable, referred to as Y, is the number of monthly working days contributed by all hospital healthcare workers at our institution. We were able to measure this variable with the help of the office of human resources. We then calculated the ICA as ICA=X/Y. According to our stated goal, the ICA should be ≥1.

In our hospital, ICA was <1; it was 0.57 for pants and 0.60 for white gowns. Thus, we sought to determine why all healthcare workers did not change attire daily. In some inpatient units, the reasons were material. For example, the number of outfits worn by doctors was insufficient. An outfit is worn for 1 day then put into the dirty laundry circuit. The dirty outfits are sent to the laundry service at an outside company. The clean garments are returned to the hospital and are distributed to the units. The entire procedure takes 2 weeks. Consequently, each doctor needs at least 12 complete outfits.

To improve the ICA, we changed the contract with the laundry company so that each healthcare worker and doctor were provided the exact number of garments according to his/her scheduled work days. We launched an information campaign regarding wearing and changing attire. The management of our hospital took part in this information campaign to emphasize its importance to all healthcare workers. Hygiene training was provided regarding awareness of the problems of changing attire and mobile phone contamination. In 6 months, we will complete a “before-and-after” study to determine the impact of these measures on our ICA and the number of cross infections in our hospital.
