Partnership with Psychiatrische Dienste Aargau


Bern / Windisch, May 23, 2023 – YLAH AG and PDAG will be joining forces. In Praxis für Ihre psychische Gesundheit Zofingen, one of the eight outpatient locations of PDAG, YLAH’s therapy platform is being tested in a pilot project and will be expanded to other locations in the future.

The approach of so-called blended psychotherapy, i.e., the combination of therapy sessions and elements of online therapy, is considered a promising method. Professionals can use it to digitally assign personalized support and small tasks to their patients between individual sessions. In this way, they engage with their mental health between face-to-face appointments and are motivated to integrate therapeutic activities into their daily lives. This hybrid approach is considered by experts to be more effective and efficient than stand-alone sessions or online-only therapy. YLAH focuses in a first step on the indications anxiety disorder and depression as well as related treatment topics.

The CEO of YLAH AG, Florence von Gunten, expresses her delight:

«The collaboration with PDAG is another milestone for us. Jointly analyzing the current treatment process from a psychotherapeutic perspective as well as innovation and digitalization management was an important first step. We learned a lot about current challenges and how PDAG can ideally support their patients, doctors and therapists with YLAH.» 

Katrin Hanno, MD, is Center Director and Chief Physician of Zentrum für Psychiatrie und Psychotherapie (ZPPA) and Deputy Clinic Director of PDAG. She manages the Zofingen site and sees a lot of potential in the collaboration with YLAH:

«We see YLAH’s therapy platform as an innovative approach to integrate online interventions into regular psychotherapy. We expect this to result in more goal-oriented and flexible treatments, while at the same time making more effective use of our human resources. In addition, YLAH gives us the opportunity to reduce waiting times or use them therapeutically.»

Benedikt Niederer, Head of Innovation and Digitalization Management at PDAG, adds:

«The collaboration with YLAH is a prime example of how innovation can be meaningfully lived in a dynamic company. The partnership introduces PDAG to new, digital ways of working, and YLAH in turn gets the opportunity to apply and improve its product in a proven clinical setting and under real working conditions. This type of collaboration creates effectively measurable added value for all parties involved, especially for patients.»

In addition to integrating YLAH into the current therapy path, joint research activities are also planned. In this way, the latest scientific findings are to be used profitably with the help of digitalisation and integrated into everyday clinical practice. The various projects are the responsibility of Prof. Dr. med. Marc Walter, Head and Chief Physician of Klinik für Psychiatrie und Psychotherapie (KPP).

«By breaking new ground with the help of digitalisation, PDAG once again underline their innovative character»,
