Clients & Projects
Client: CC care aktiv GmbH
Project: Training for the Creation of Educational Videos in Outpatient Infusion Therapy
CC care aktiv GmbH is a service company based in Lower Saxony that organizes, coordinates, and provides outpatient and home-based infusion therapies – including corresponding training programs. The company’s management had considered producing instructional videos on infusion therapy and the use of medical devices, or enhancing existing training sessions with video tutorials.
CITAH contributed its expertise in video production and scientific visualization. In collaboration with staff from CC care, our team conceptualized, filmed, and edited two instructional videos in the intensive care laboratory of OFFIS e.V.. The staff were not only involved in the production process but also received training in video production techniques.
Client: Berlin School of Fine Arts and Design, Kunstschule Berlin
Project: Digital Check-In Solution for Workshops and Evening Courses
The Berlin School of Fine Arts and Design offers not only full-time training programs but also evening courses in various artistic disciplines.
Until recently, attendance was tracked using physical punch cards. However, these were often forgotten or not stamped, creating challenges for course organization and management.
CITAH developed a digital check-in app based on Microsoft Power Apps and Power Automate. Purchased courses are now automatically entered into a Microsoft List, and participants receive a QR code via email. Instructors scan this code using the app, which registers attendance and updates the remaining course units and number of days left. This provides the school with a transparent digital overview of course participation and a reliable attendance tracking system.
Project: Automated System for Internal Satisfaction Surveys
Another project for the School of Fine Arts and Design:
With nearly 200 students and around 30 instructors, it is essential for the school to regularly gather up-to-date feedback and identify potential dissatisfaction at an early stage. However, previous surveys generated little interest among students – participation was low, and certain issues never even reached the school administration.
On behalf of the school, CITAH conducted interviews with students and staff to understand which topics matter most to them and which question formats would increase engagement and willingness to participate. Based on these insights, the existing questionnaires were revised, and an automated system was developed that distributes and processes surveys at the right time and in an appropriate format.
The result: more participants, more valuable and timely feedback – and overall, a more effective quality management system.
Client: Sakta GmbH
Project: Telegram Chatbot and Dashboard for Automation in Logistics Operations
Sakta GmbH is a small transportation company based in Munich, operating with around ten vehicles.
The managing director’s daily work was previously dominated by manual, time-consuming tasks – especially in communication with drivers. Work assignments were sent individually via WhatsApp, while confirmations, photos, vehicle inspections, and documents had to be collected manually and then entered and archived by hand in spreadsheets – a process prone to errors and inefficiencies.
CITAH developed a comprehensive automation solution:
- A central dashboard was created using Google Sheets, where the weekly work schedule is maintained. All updates, driver and vehicle statuses, and job details are displayed in real time.
- A Telegram chatbot handles all communication with drivers: it automatically sends out shift schedules, requests photos of vehicle inspections, receipts, and proof of task completion, and stores all data in a structured way in spreadsheets and on Google Drive. The chatbot supports both German and Russian – ideal for the multilingual team.
The result: significant time savings, streamlined workflows, better oversight of vehicle conditions, and earlier detection of technical defects – ultimately leading to a noticeable reduction in maintenance costs.
Client: Leibniz-Institut für Präventionsforschung und Epidemiologie – BIPS GmbH, Bremen Cancer Registry
Project: Prototype of an Online Report for Cancer Registry Data
Client: Deutsche Krebsregister e.V. (German Cancer Registries)
Project: Dashboard for the Visualization of Cancer Incidence and Mortality
Client: ICSmed AG
Project: AI-Assisted Medical Report Documentation
Client: Jan Gerlach Medical Practice
Project: Strategies for Digitization and Telemedicine (Virtual Avatar Clinic, Chatbot)
The general medical practice Gerlach & Kollegen is developing an AI-assisted telemedical practice to reduce workload through automation and telemedicine.
CITAH analyzed the core workflows of the practice and reviewed digital tools and telemedical approaches. Based on this analysis, optimization proposals were developed, and a digital chatbot for preliminary medical history (pre-anamnesis) was tested.
Client: MinkTec GmbH
Project: In-Depth Laboratory Study for the Validation of a Sensor Shirt
The high-tech startup MinkTec developed the “rectify” sensor shirt, which continuously captures the shape of the spine around the clock. An app provides users with real-time feedback on their posture and a daily summary.
CITAH supported MinkTec in validating the sensor shirt. In an in-depth laboratory study, we examined its measurement accuracy by having study participants perform a range of movement exercises covering the full range of motion of the back. The sensor data was compared to a marker-based optical reference system, considered the gold standard in motion analysis.
In addition, we recorded further fitness exercises to build a training dataset for automatic exercise recognition. The study contributed to the product’s further development and the implementation of new innovative approaches.
Client: Radiologie am St. Joseph Stift GbR
Project: Development of an IT Security Strategy for a Radiology Practice
Radiology at St. Joseph-Stift, a large radiology and nuclear medicine group practice in Bremen, modernized its IT infrastructure and received support from the CITAH team through a Cyber Risk Check in accordance with DIN SPEC 27076 – a standardized questionnaire for IT security consulting tailored to small and medium-sized enterprises.
The questionnaire highlights areas where the IT security concept is already well developed and identifies potential gaps that have not yet been addressed. As a result, a concrete list of recommendations is generated to help improve and complete the overall security concept.
Client: Nursing Schools of the Osnabrück District in Melle
Project: Experiences with VR and AR for Students
We support nursing schools in introducing their trainees to innovative care technologies and teaching and learning methods based on Virtual Reality (VR) and Augmented Reality (AR). Through lab visits at OFFIS in Oldenburg, trainees have the opportunity to explore and try out these technologies in a healthcare context.
Our service includes preparatory and follow-up sessions at vocational schools, as well as the hands-on visit to the lab.
One example from our first reporting period is the collaboration with the vocational schools of the Osnabrück district in Melle. The trainees received a theoretical introduction to the fundamentals of digital transformation and were able to develop new competencies through practical exercises. The on-site visit and use of care applications in various settings enabled them to test the applications themselves and reflect on their experiences.
In a concluding session, the reflection results were presented, and individual questions were discussed with the trainees. They also had the opportunity to develop solutions for technical challenges and present them to one another. This experience helped raise awareness among each participant about the digital transformation in healthcare and prepared them for future technologies and applications.
Client: care pioneers GmbH
Project: Data Management and Analysis in Outpatient Care
The Care Pioneers GmbH in Oldenburg provide consulting and support for care facilities and municipalities.
CITAH supported them in the development and testing of an improved data management and analysis system that enables more efficient handling and evaluation of service data.
Following an initial requirements analysis, a solution was implemented that, unlike the previous system, offers optimized management of billing and master data, as well as dynamic analysis of time series data from individual care providers or entire provider groups. In addition, a key performance indicator (KPI) system was introduced, allowing care providers to quickly identify problematic billing items and address them efficiently and effectively.
On the provider side, input errors are now avoided from the outset through various plausibility checks and data validation mechanisms during data entry. This significantly reduces the overall workload for the project.
The collaboration began with a two-day job shadowing visit by the CITAH team at the hospice, during which digitalization potentials were identified together with staff – potentials that CITAH could later help to realize.
One such identified area was the creation and use of digital letterhead. Since each department of the hospice uses its own individual letterhead, the hospice was looking for a solution that would allow users to easily apply the appropriate letterhead to a document with just a few clicks. CITAH implemented a solution based on software already in use at the hospice.
Even before the on-site visit, the hospice had acquired software for electronic signatures. However, as is often the case in the healthcare sector, there was a lack of time and personnel to become familiar with the system. CITAH provided support by assigning an OFFIS e.V. staff member to explore the software and deliver a tailored onboarding session based on the hospice’s specific needs.
Another key issue was internal appointment scheduling and coordinating meetings with over 100 volunteers. Here, the CITAH team proposed a free, GDPR-compliant tool and supported its implementation.
Client: HUM Systems GmbH
Project: AI-Based Fall Detection with the Livy Care System
The Livy Care System by HUM Systems uses radar and computer vision to detect when a person in need of care has fallen or is lying on the floor and alerts caregivers accordingly.
To avoid mistakenly classifying a person lying in bed as having fallen, the bed area must be defined as a “safe zone.” Until now, this safe zone had to be manually marked during device setup. However, in nursing homes or hospitals, beds are often moved. To avoid having to reconfigure the safe zone every time a bed is relocated, HUM Systems aims to implement an AI-based algorithm that can automatically detect the bed and its position.
To support this, CITAH created the necessary training data by capturing images of beds in various environments and lighting conditions in the care lab at OFFIS e.V., and manually labeling them. HUM Systems then used these images to train a machine learning algorithm to reliably identify beds.
The training data is also available as an open dataset and can be used by other companies and for other application scenarios.
