Which method is worthwhile?
Cost check: UV vs. DesiCoach
The Robert Koch Institute (RKI) recommends annual practical training in hand disinfection for all employees. But which method is more economically viable: the traditional UV method or the innovative DesiCoach® system?
Let’s take a closer look at both systems:
The classic method:
The UV method under the microscope
The hands are rubbed with a fluorescent solution and examined under a black light – weak spots become visible. This is an established procedure, no question. But how efficient is it when it comes to training entire teams?
- The material costs: The cost per person is approximately €0.27. For 20 people, e.g., as part of the annual hygiene training, this amounts to €5.40. (We assume that a UV box is already in place and will not incur any additional costs for repairs or replacement parts—the ideal scenario, so to speak.)
- The key point is time: During the training, each person must go to the UV box one-on-one. Everyone else has to wait. With a typical group size of 20 people, the time required quickly adds up: our analysis shows a time requirement of approximately 15 minutes for the entire group, just for this one check. Valuable minutes while the rest of the team waits.
The innovative alternative:
The DesiCoach method
DesiCoach® takes a different approach. Instead of 1:1 support, the system enables several people at the same time to train under central supervision. The result? A drastic time saving.
- The material costs: The cost here is €2.00 per person, so €40.00 for our example group of 20 people.
- Turbo training: The same group of 20 people with DesiCoach only needs about 5 minutes for two practical applications (training with a dye and a decolorizer). This is not only 10 minutes less than with the UV method, but also twice as many opportunities to optimize your own hygiene technique!

Difference in time required → The UV method requires 10 minutes more time.
Difference in material costs → DesiCoach® is per training unit 34,60 € more expensive.
Result → From a salary of more than 10,39 € DesiCoach® is cheaper per hour.
How valuable is your team’s time?
Considering only the material costs, the UV method seems cheaper – at least if you already own a UV lamp. But that's only part of the truth.
The Time savings of 10 minutes per training with DesiCoach® means for a group of 20 people a Total saving of 200 minutes – that’s 3.33 hours of work!
Important time that we can use...
- Freed-up time can be spent on value-adding activities.
- Overtime is an important cost factor and places additional strain on staff.
So when does the relationship between material costs and time expenditure tip?
In order to calculate which training method is actually financially worthwhile, we need to hourly wage regard:
If we divide the additional costs for DesiCoach® (34.60 €) by the saved working hours (3.33 hours), we get 10.39 € per hourIf your team earns more than that on average, the time factor becomes crucial.
Conclusion → Does your team earn on average more than 10,39 € per hour? Then DesiCoach® is the most cost-effective method!
Didactics and handling:
Additional benefits of DesiCoach
Of course, cost-effectiveness is only one aspect – DesiCoach® offers other decisive advantages:
- Didactically more modern: Through the double application (dyeing, decolorizing) identified problem areas can be trained immediately
- Easier handling: No technical equipment required, can be used simultaneously
- Higher participant acceptance: No frustrating waiting times, more fun training
- Resource-saving: Long durability and full use of materials
Conclusion:
DesiCoach for future-oriented institutions
Choosing DesiCoach® is not only a decision for economic efficiency, but also for modern training methods. The initially higher material costs are already amortized at an average hourly rate of €10.39 – a figure that is usually significantly exceeded.
With DesiCoach®, you invest in efficient training, increased employee satisfaction, and ultimately, better infection control. A future-oriented solution that pays off.
