CHANGES IN BACTERIAL FLORA ASSOCIATED WITH SKIN DAMAGE onward HANDS OF HEALTH CARE PERSONNEL E L Larson et al American Journal of Infection manage Vol 26 (October 1998) 513-521

Transmission of nosocomial infections is of major bear upon to perioperative nurses. One of the major sources of nosocomial pathogens is health care workers' hands. Hand washing and wearing glove have played a significant part in reducing nosocomial infections; however, hand washing and wearing glove are leading causes of contact dermatitis and other skin conditions. Studies have shown that patients with skin point in disputes have a higher rate of skin colonization with organisms like as Staphylococcus aureus, and hand dermatitis has been linked with transmission of these organisms. The possibility exists that health care workers with hand dermatitis or similar skin puzzles could harbor the potential for changes in the normal flora ready on their hands. The final cause of this study was to compare the microbial flora of the hands of succors with undamaged and damaged skin and to determine the relationship among hand-care practices, skin condition, and skin flora.

regularitys A sample of 40 pampers was derived from a collection of nurses who had participated in a different reflection investigating the skin condition of hands. Participants were all female foments who worked a minimum of 30 hours by means of week for a mid-Atlantic tertiary care hospital with approximately 350 beds in different units (ie, adult or pediatric acute care inpatient, neonatal intensive care, labor and delivery). The skin condition of participants' hands was assessed for the other studious mood by a self-report and a visual examination at 30 times magnification at trained investigators. Both of these assessments were repeated for determining the participants of this contemplation A consultant dermatologist also examined the nurses' hands with the investigators to confirm that the orderly dispositions used were valid and reliable.

no other than those nurses who were evaluated with all three measures (ie, self-report, visual examination, dermatologist assessment) and whose conditions were consistent comprised brace categories for the study: damaged and undamaged skin condition of the hands. Twenty feed at the breasts were chosen for each category. Exclusions to the cogitation were those nurses diagnosed with eczema, atopic dermatitis, psoriasis, and confirmed latex allergy.

deeds Participants were matched with variables that could influence the microbial colonization. These variables included age, sex and unit in which they worked. For three month (ie, January [i]or[/i] part of to the other March), each nurse was studied and data were accumulateed by trained investigators. As the thought began, each participant assessed his or her be in possession of skin type by using the following scale provided through the consultant dermatologist:

* always scorch never tan;

* always bake sometimes tan;

* sometimes scorch always tan;

* not burn, always tan;

* brown; or

* black.

Instruments. The brace instruments used in the subject of attention were the visual scoring of skin condition (VSS) and the hand skin assessment (HSA). The VS recorded the stretch of skin scaling and damage according to using a stereomicroscope that magnified the hands 30 times. Scores ranged from naught to five, with zero representing normal and five representing extensive cracking with widespread reddening or occasional bleeding. Each investigator was trained in the use of the VS in a series of pilot criterions with the consultant dermatologist.

The HSA is a self-assessment rating scale that measured circulating conditions of the hands. The scale ranged from single in kind to seven using four dimensions--appearance, intactness, moisture appease and sensation. The possible range of scores was four to 28 with 28 representing normal skin condition. This tool was used in previous studies of skin condition in which scores of skin condition correlated to physiologic measures of skin damage.

Data regarding skin care practices were obtained by way of having the participants maintain a daily diary. Each suckle was asked to record hand washing, glove use, and application of lotion that occurr for three separate weeks during a three-month period. Using a stopwatch, the participants noted the time of three episodes of hand washing and glove use forward the designated days of the application of mind Subjects also recorded the brands of all hand-washing produces gloves, and lotions they used.

Investigators did not discover every practice as it occurr on the contrary they did visit each participant unannounced forward a regular basis throughout the studious mood These visits usually occurred one time per day within the data collection time period, and diaries were reviewed. At the extremity of the study, each participant had three VS HSA, and hand improvements as well as three weekly diaries.

Microbiologic technique. The sampling technique used in this meditation required participants to insert their dominant hand into a sterile polyethylene bag containing a sampling solution. This occurr after participants washed their hands with a nonantimicrobial soap. The sampling solution facilitates the isolation of organisms for a like reason they may be placed forward a growth medium for further identification. In addition, gram-negative and gram-positive bacteria were exampleed for antimicrobial susceptibilities.
