Therapy sessions during the corona pandemic

Trotec air cleaners make encounters safe

Diagram: Number of weekly patient requests in psychotherapists’ practices

The corona pandemic has caught many psychotherapists unprepared.

The restrictions in our daily lives such as curfews, restraining orders, decree on working from home, but also closed schools, nursery schools and care facilities – all this has left its marks in our society. In the pandemic, many adults are suffering from anxiety disorders, existential fears and depressions. But the pandemic has also made itself felt on children and youths. The evaluation of several studies indicates that frequency of psychological symptoms has increased. For a large number of girls and boys, disorders requiring treatment were detectable, for example showing in symptoms relating to an attention deficit/hyperactivity disorder or temper tantrums and outbursts of fury, i.e. symptoms of an oppositional behaviour disorder. This has led to a substantially increased demand for psychotherapeutic treatments.

Significant increase in patient requests

A survey conducted by the DPtV (German association of psychotherapists) showed that last year an average of 4.9 requests for therapy were made every week. This number has already increased to 6.9 requests this year, and the proportion of psychotherapists who have received more than ten patient requests per week has even doubled. However, the survey shows that only one out of four patients requesting therapy receives an appointment for an initial interview. The consultation of new patients by phone, as requested by the DPtV for some time now, is refused by the National Association of Statutory Health Insurance Physicians (KBV).

The situation still is as it was: Only patients with at least one appointment in the practice in the six quarters before the consultation are considered as “known patients” and can make use of the option for telephone consultation. An acute treatment without personal contact, for instance via psychotherapeutic video sessions, is therefore almost rendered impossible. A situation that is equally afflicting for both patients and therapists.

High corona infection risk during psychotherapeutic sessions

But there is something that troubles many therapists even more. The large flow of patients in practices inevitably increases the therapists’ personal risk of a corona infection. Since psychotherapeutic sessions take place in a face-to-face situation, the risk that each party will infect the other is especially high. Even if a patient is vaccinated, recovered or has a negative test result – the risk of an infection literally is “in the air”.

Infectious aerosols spread in the room…
… and remain there for some time.

Aerosols spread in the room permanently

Numerous scientific studies show that, merely by breathing and mainly through talking, aerosol particles carrying the SARS-CoV-2-virus already spread across several metres and can float in the room air infectiously for several hours. Even though wearing a mouth nose mask may offer reliable protection against larger droplets, it does not fully prevent the inhalation of these tiny aerosol particles. Therefore, during a therapy session of approx. 40 minutes in a poorly ventilated room it is almost impossible to protect you from inhaling air that has been inhaled and exhaled again by the person facing you – and which thus might be contaminated with infectious coronaviruses. To make matters worse, the breaks between the tightly scheduled treatment appointments in most cases are so short that there is only little time to to ventilate the room sufficiently after a session. As a result, potential virus particles remain in the room air and increase with every therapy session.

Trotec high-performance air purifiers reduce the infection risk in your practice

Providing for powerful protection against airborne infection risks during the therapy session Mobile Trotec high-performance air purifiers. Specially designed for aerosol filtering and equipped with a highly efficient HEPA filter of filter class H14 (certified in compliance with EN 1822), room air cleaners of the TAC series as well as design high-performance air purifier AirgoClean One specially constructed for medical practices, reduce the number of aerosol particles in the room by up to 99.995 percent – and this after only a few minutes.

It just takes 6 to 15 minutes for a high-performance air purifier TAC V+ to reduce the viral load in a room with a size of 80 qm by 50 %. In smaller rooms, the reduction by half of the load only even takes 3 minutes! By the technical air filtration the room air is cleaned continuously in the HEPA filter and is cleared from pathogens such as SARS-CoV-2- or influenza viruses, but also from bacteria, allergens or fine dust particles. In this way, the risk of an indirect infection is substantially reduced, even for sessions of a longer duration.

Air cleaners make therapy meetings safe again
Sound level comparison: Air cleaners are almost as silent as a wristwatch

Air hygiene creates space for a trusting atmosphere in meetings

Another good reason using mobile air cleaners is the personal well-being during the treatment. Undisturbed communication between the therapist and patient is the centre of every therapy session. Therefore it is absolutely necessary to reduce sounds of noise, so as to prevent negative impacts on the atmosphere. Hence, the idea of open windows to supply the room with fresh air is only practicable to a limited extent. Ventilation in the oncoming winter proves even more difficult – with outdoor temperatures around the freezing point. Then the room temperature will inevitably decrease every time the window is opened for the purpose of ventilation. The result will be soaring heating costs. Let alone your well-being that will also suffer by chilly indoor temperatures. By the use of a mobile high-performance air purifier, however, the ventilation intervals can be reduced without neglecting your own self-care and the patient’s health protection.

Good to know: Modern high-performance air purifier like the TAC V+ clean the air almost without making any sound. With a sound level of just 31 dB(A), the sound of a TAC room air cleaner is as low as the ticking of a wristwatch, whereas traffic noise can reach a noise level of up to 65 dB(A).

In numerous practices, hospitals and medical facilities, TAC high-performance air purifiers have therefore already been used since the start of the pandemic, in order to protect both the medical practitioner and the patients as well as possible against an airborne transmission of the coronavirus.

Proven effectiveness for an unburdened psychotherapy

Scientific studies certify a high effectiveness in preventing indirect infection with the coronavirus for Trotec's high-performance air purifiers – first and foremost the highly acclaimed studies by Prof. Christian Kähler. In his research studies, the aerosol expert from Munich could establish that by using the TAC V+ high-performance air purifier, within a very short time, the viral load in closed rooms can be reduced to a level that poses next to no hazard anymore.
