The private care market in Zagreb
The 2021 census counted 767,131 residents in the City of Zagreb.1 The largest districts were Sesvete at 70,800, Trešnjevka South at 65,324 and Novi Zagreb West at 63,917, with 31,209 in Donji Grad at the centre.1
Private practices and polyclinics are founded, moved or expanded with the involvement of the Croatian Medical Chamber, which also keeps the register of doctors and issues each doctor's licence to practise independently.3 The Ministry of Health oversees the health system, and its site carries a section on health tourism for patients who travel to Croatia for care.4
The rules a clinic in Zagreb works under
The Croatian Personal Data Protection Agency, AZOP, is the data protection authority, and it publishes its decisions, opinions and administrative fines along with guidance on aligning with the GDPR.5
The Law on Data and Information in Healthcare, in force since 2019, sets out how health data is collected and used.2 Health documentation is kept in electronic form by every provider of health care.2 Patients' medical documentation is stored in Croatia's health information infrastructure and exchanged through its services, and the central electronic health record, the e-Karton, is held in CEZIH.2 Only authorised health workers involved in the patient's treatment and care may open the e-Karton.2 The Croatian Health Insurance Fund manages CEZIH and checks whether an IT solution is ready to connect to it.2
Each doctor needs a licence from the Croatian Medical Chamber, renewed when the doctor has collected at least 120 continuing education points in six years and meets membership duties.3
wai hosts each clinic's records in its own country, under that country's rules. We set this up with your clinic. wai is compliant with these rules and built for clinics in Zagreb. wai is built to connect to CEZIH. We set up your clinic's connection with you.
The languages Zagreb patients write in
Croatian dominates, with 741,626 of the city's residents naming it as mother tongue in 2021.1 The next largest groups were Bosnian at 4,343, Albanian at 3,300, Serbian at 2,482 and Slovenian at 1,140, with 3,507 naming other languages.1
wai works in any language. Patients can answer intake questions by voice in their own language, and the clinician reads the answers before the visit.6 A visitor writing in English or German from a hotel on Ban Jelačić Square gets a reply drafted in that language, and the receptionist approves it before it goes.
What a demo shows in Zagreb
A WhatsApp arrives at 21:50 on Sunday from a woman in Trešnjevka asking whether her father can see the internist this week about his blood pressure. wai reads the internist's busy times from Google Calendar, Outlook or Apple Calendar, offers two open Tuesday times and drafts a reply in Croatian. The receptionist approves it at 7:45 on Monday.
She books on the polyclinic's own website, earliest time first, and pays the deposit in euros by card or Apple Pay through the clinic's own Stripe account, with the clinic as merchant of record.7 Her father receives a confirmation, a receipt and an intake questionnaire, and a missed call that morning becomes a drafted text for the team to send.
In the consultation the internist tells him the scribe is on, then reads the drafted note, edits it and signs. wai drafts the letter to his family doctor from the signed note, and every message, draft, approval and signature is logged for the clinic to export.8
For hospitals, insurers and public bodies in Croatia
A hospital, a supplementary insurer or a public body can commission a system built on wai for one care pathway, with records hosted in Croatia, connection to CEZIH scoped in, and the rights to data, configuration and models written into the contract. How that works is on the organisations page.
Where to start
First, list where the clinic's medical documentation lives today and how it reaches CEZIH.2 Second, check every doctor's Medical Chamber licence date and points total.3 Third, add a line to intake telling patients an AI scribe drafts the note and the doctor signs it, as the guide on who signs an AI note sets out.
Then count last month's enquiries by channel and hour, and bring them to a fifteen-minute demo. Prices are on the pricing page.
Bring a week of messages from your patients and watch each reply drafted in their language for your team to approve.
