Recommendations and requirements for soap and hand rub dispensers in healthcare facilities.

Abstract

Hand hygiene is one of the most important measures to prevent transmission of infectious agents and plays a major role in prevention of infection in any type of healthcare setting. While requirements for the efficacy of hand disinfectants are defined in European testing norms such as the EN 1500 for hygienic hand disinfection or EN 12791 for surgical hand preparation, no specific recommendations for hand rub dispensers and liquid soap dispensers have been given yet. Therefore, the intention of the present recommendation on soap and hand rub dispensers in healthcare facilities is to close this gap and to enhance future improvement of dispenser functionality and design. Regardless of manufacture and design of a hand rub or liquid soap dispensers the following requirements shall be met in healthcare facilities:Triggering the dispenser must be possible without using hands. Sensor- or elbow-operated dispensers both fulfill this requirement. Dispensers must be only refillable in a modality where the content, be it a hand rub or liquid soap, cannot be contaminated. This is achieved best by using replaceable cartridge systems. Refilling through “top-up” must not be possible. The disperser should allow usage of different types of cartridges made by different manufacturers. Dispensers must be operated and maintained such that a microbial contamination of the pump nozzle may easily be avoided. It must be possible to identify the products used in a dispenser easily and without any manipulation. Identifying the type of product, be it a hand rub or a liquid soap, as well as reading the product's name and critical manufacturers' warnings must be possible at any time. The disperser must allow identification of the level of the used product without any further manipulation at any time. The design of the dispenser must allow easy cleaning and disinfection the outside and inside of the dispenser. The manufacturer of the dispenser must provide the user with information on applicable chemicals and cleaning products. It must be possible to reprocess the dispenser and all of its permanent parts by applying machine based thermal disinfection at an A0-value of minimum 60 (e.g. 80°C/1 minute). Automatically portioning dispensers shall not fail during 200 hubs. The maximal allowed failure rate shall not exceed 1% (2 out of 200 consecutive hubs). A dispenser used for alcohol based hand rubs must allow keeping the alcohol concentration constant over a time period of 3 months. The maximum acceptable decrease in the concentration of the alcohol shall not exceed 5%. Liquid soap and hand rub dispensers with single-use pumps, ideally already mounted on the cartridge and to be discharged with the empty cartridge, are preferable. If pumps are used on the next consecutive cartridge, the manufacturer must provide the user with a detailed introduction for cleansing and reprocessing before further use. Because of forensic reasons it is recommended to place a good readable sign on the dispenser indicating e.g. “Apply alcohol based hand rubs only on the hand! Do not drink, avoid spraying into the eye or application on mucous membranes”. It is regarded as an additional benefit, if the dispenser is able to document the consumption of hand rub or the frequency of hubs either mechanically or electronically.
