Measurably Improving Hand Hygiene

Although hand hygiene is accepted as the most important measure for preventing the spread of infections, it is rarely treated as a primary component of saving patient lives. Careful and thorough hand hygiene is the simplest, most effective, and economical measure against the spread of infections and multi-resistant pathogens.

Achieving sustained and effective improvement of hand hygiene behaviour requires data on existing behavior to be reliable. When data is available, it is often tainted by inaccurate methods of observation. The Hawthorne-Effect, which states that behaviour can be artificially altered during periods of observation, is problematic for traditional methods of group hygiene monitoring.

The Ophardt Hygiene Monitoring System® (OHMS) provides an integrated approach to hand hygiene compliance solutions. Together with the ingo-man® plus Weco dispenser, OHMS enables customers to monitor hand hygiene compliance wirelessly.

Equipped with information collected by OHMS, users can optimize hand hygiene compliance by coordinating dispenser locations with areas of low or high usage, share relevant feedback with coworkers, and provide targeted hand hygiene training more effectively. Integrating OHMS into hospitals and other medical care facilities can lead to a measured improvement in patient care treatment quality.

OHMS - Structure and Function


ingo-man® plus Weco dispenser

Every time one of our Weco® dispensers is used, a timestamped signal, noting location and amount of liquid dispensed, is sent over pre-existing WiFi infrastructure and stored in a central database. The identity of the individual user is not recorded – ensuring that privacy laws are never infringed.



Data collected from Weco® dispensers is collated and evaluated using specially developed software. With this software, web-based reports can be quickly and easily generated to reveal usage frequency and disinfectant consumption of each dispenser.



Reporting is made easy using the OHMS database. Usage data is updated in real time, and can be grouped spatially by hallway, unit, or department, as well as temporally by hour, day, week, or month.


Healthcare-associated infections and hand hygiene

Healthcare-associated infections.

In Europe alone, about 2.6 million episodes of healthcare-associated infections occur every year, with up to 90,000 directly attributable cases leading to death. Patients in intensive care units have an increased risk of developing healthcare-associated infections.


Economic Burden.

Nosocomial infections – infections related to a hospital stay – can have a significant impact on healthcare systems, particularly when considering the potential spread of multi-resistant pathogens and their increased treatment complexity.

The Solution: Hand hygiene.

Numerous studies confirm: An improvement in hand hygiene compliance results in a lower healthcare-associated infection rate. Research demonstrates that a 37% increase in hand hygiene compliance rates can result in a reduction of 41% in healthcare-associated infections. Valid and continuous data about hand hygiene behavior are crucial for improving compliance.

A success story.

The impact of OHMS on hand hygiene compliance and healthcare associated infections was analyzed during a clinical investigation over a one-year period. Hand hygiene behavior was actively analyzed in the BDH-clinic Greifswald, in addition to the implementation of focused training sessions at one station in the clinic. The study was successful - hand hygiene quality was improved and the infection rate dropped by nearly 30%.

Measurably improving hand hygiene since 2011.

Since 2011, OHMS has been reliably working in a diverse range of clinics and medical facilities across Europe. Since that point in time, OHMS registered more than 25 million hand hygiene activations. With more more than 30 installations, OHMS is the European market leader in electronic hand hygiene monitoring systems.
