Inadequacy of manual cleaning for reprocessing single-use, triple-lumen sphinctertomes: simulated-use testing comparing manual with automated cleaning methods.
Despite widespread reuse of single-use sphinctertomes, publications regarding the adequacy of reprocessing are conflicting and the cautery wire channel is seldom evaluated. Our objective was to use thickened artificial test soil containing microorganisms to perform simulated-use tests combined with in-situ and destructive testing to evaluate cleaning efficacy and ethylene oxide sterilization of single-use triple lumen sphinctertomes. ⋯ Only retro-flushing done within 24 hours of use provided adequate cleaning for multi-lumen, single-use sphinctertomes. Our data validate the efficacy of reprocessing sphinctertomes once with SI-Auto retro-flush cleaning followed by 2 hours of ethylene oxide sterilization.

Comparative StudyRates of hand disinfection associated with glove use, patient isolation, and changes between exposure to various body sites.
Handwashing is the most effective and economic intervention shown to reduce nosocomial infection rates. However, studies have consistently documented low hand disinfection compliance. Literature regarding the roles that concomitant glove use and isolation precautions play in health care worker compliance with hand disinfection is limited. It is unclear whether workers change gloves and disinfect hands adequately between exposures to different body sites/secretions while caring for a patient. ⋯ Glove use increases compliance with hand disinfection. Isolation precautions do not increase compliance. Workers do not appropriately comply with disinfection guidelines when attending to multiple body sites/secretions on the same patient. Compliance with hand disinfection remains low.

Technique to determine contamination exposure routes and the economic efficiency of folded paper-towel dispensing.
Handwashing and hand drying are key elements of infection control. Paper towels are generally accepted as the most hygienic means of drying hands and are often distributed from generic dispensers. Effective dispensing of towels is of importance economically and may influence infection control objectives if hands become contaminated during hand drying. ⋯ Participants of a shorter height obtained a lower incidence of dispensing malfunctions using all towel products and type. The results indicated likely contamination exposure routes and wastage levels for each towel type. Environmental service managers and infection control practitioners should carefully consider, for economic and infection control reasons, the siting and design of towel dispensers and the types of towel purchased.

Use of alcohol hand sanitizer as an infection control strategy in an acute care facility.
Nosocomial infections are a major problem in health care facilities, resulting in extended durations of care, substantial morbidity and mortality, and excess costs. Since alcohol gel hand sanitizers combine high immediate antimicrobial efficacy with ease of use, this study was carried out to determine the effect of the use of an alcohol gel hand sanitizer by caregivers on infection types and rates in an acute care facility. Patients were educated about the study through a poster on the unit, and teachable patients were given portable bottles of the alcohol hand gel for bedside use, along with an educational brochure explaining how and why to practice good hand hygiene. ⋯ This study indicates that use of an alcohol gel hand sanitizer can decrease infection rates and provide an additional tool for an effective infection control program in acute care facilities.
