The telephone is the bottleneck of outpatient care in Germany. 44 percent of statutorily insured patients are dissatisfied with their practice's phone reachability, and despite all the portals only 4 to 7 percent book online (GKV umbrella association, 2024). Through this bottleneck run 579 million treatment cases a year.
At the other end of the line, the staff is missing: in a Bremen survey, one practice in four could not fill a single medical-assistant position in twelve months, and 57.8 percent of physicians now do assistant tasks themselves. A 2024 Fresenius university study supplies the number behind it: 68 percent of medical assistants spend over 40 percent of their working time on organization and administration, not on patients.
A note on honesty before anyone quotes the usual figures: the often-cited "7,000 missing medical assistants" is the 2023 peak. The KOFA statistics show the calculated gap nearly closed by late 2025, with still around 11,700 open positions; the labor market is cooling while hospitals keep poaching with better starting salaries. We also traced the industry-standard "40 percent of calls go unanswered according to a KBV study": that study does not exist. The verified numbers above are quite enough.
The legal situation is better than its reputation
Many practices assume AI on the patient phone is legally impossible. Since December 2025 the opposite is stated in an official publication of the KBV, the federal association of statutory health insurance physicians: it classifies AI phone assistants as a low-risk application, requires an AI announcement at the start of the call, and states that a data-protection consent from the patient is generally not required, as long as the data is not used for training. Responsibility stays with the physician; the AI must not make decisions.
Cleanly implemented, this means the following is permitted today: booking, moving and cancelling appointments, capturing prescription and referral requests as messages, recording structured callback requests. The conditions have teeth though, and they sort the vendor market mercilessly:
- A data processing agreement plus a formal written confidentiality commitment of the provider under § 203 of the German Criminal Code; without it, the physician is personally criminally liable.
- § 393 of the Social Code V, the most overlooked rule: cloud processing of health data is only permitted with processing in the EU (or EEA/Switzerland), a domestic establishment of the provider, and a BSI C5 attestation, since July 2025 as Type 2. A phone assistant piping health data through a US AI API without a C5 attestation is out, however good the demo sounds.
- An AI announcement from the first sentence, today the KBV's recommendation, from 2 August 2026 an EU obligation under the AI Act.
- Emergency escalation to humans, always.
The red line: where the assistant becomes a medical device
The same technology flips legally the moment it evaluates symptoms. Whoever grades urgency, prioritizes by medical risk or gives recommendations for action is operating medicine by intended purpose, and then two regimes apply at once: the Medical Device Regulation makes such software class IIa with CE obligation, and the EU AI Act lists emergency triage systems verbatim among its high-risk categories. The boundary is not caution, it is statute: the AI captures, structures and forwards. A human does the grading. We deliberately build only on the legal side of this line and say so to every prospect in the first call.
What the software market delivers, and what stays open
The practice-software market is moving: Doctolib acquired a phone-AI company in 2024, has shipped an AI phone assistant since spring 2025 and its own AI practice-management system since November 2025, initially for three specialties only. CGM offers a system-agnostic phone assistant, medatixx an ambient documentation with EU hosting. At the same time, the incumbents' classic systems lose installations quarter after quarter per the official statistics, and their built-in AI concentrates on documentation, often as a paid add-on per specialty.
What stays open is the daily life between the systems: the electronic patient record has been mandatory for practices since October 2025, yet 81 percent of practices upload documents while only 11 percent have ever downloaded one, and 77 percent still communicate with hospitals mostly on paper. The sorting, assigning and forwarding between phone, fax, secure mail and the patient record is exactly the administrative work in which those 68 percent of assistant time disappear, and exactly where automation starts without touching treatment at all.
The business side
Staff is a practice's largest cost block at 58 percent of expenses, personnel costs rose 26.5 percent from 2020 to 2023, and real practice surpluses fell 13.3 percent in 2023 (Zi practice panel). Every administrative hour recovered directly relieves the practice's scarcest and most expensive resource. In Austria the pressure is structurally harder still: the number of physicians with insurance contracts has stagnated around 8,200 for 25 years while the population grew by over a million, private-practice physicians have more than doubled since 2000 to nearly 12,000, and from 1 January 2026 they too are comprehensively obliged to use e-card and the ELGA health record. The digitalization duties are coming; the staff is not.
Whether your practice has an automation case is a matter for a free intro call, and about a third of those calls end with our advice to wait. What projects of this kind cost is in our pricing overview, with sources, and how we build sign-off steps as a principle is in draft plus sign-off.
