In a hospital, or in a healthcare organisation with several units, patient records are already held in a system. The hospital information management system (HBYS) was built for admissions, medical records, billing and submitting data to public institutions, and it does those jobs. The gap usually opens up not on the clinical side but on the operations side: managing appointments and resource utilisation, following up treatment plans left unfinished, bringing the patient back, matching consumable and implant costs to the procedure, making productivity visible by unit and by clinician. In most organisations these are either never measured at all, or they run in individual Excel files, dependent on the effort of particular people. The main system is not defective for failing to do them; these jobs fall outside what it was designed for.
Once this gap is noticed, the first solution that comes to mind is usually the wrong one: replacing the existing system entirely. Yet the main patient record system carries the organisation's historical data, its billing structure and its obligations to submit data to external institutions; replacing it is both a major risk and, in most organisations, no solution to the real problem. At Pan Innovation House we do not write the HBYS itself. Main systems such as Akgün, Probel and Monad stay where they are; we build an operations layer that works alongside them. We state this boundary at the outset, because the most common disappointment in this field surfaces halfway through a project whose scope was stretched as far as the main system.
The second boundary is the regulated areas. Provision and invoicing transactions through Medula (the Turkish social security health claims system), data submission to e-Nabız (the national personal health record) and the MHRS (central physician appointment system) booking flow are subject to an authorisation regime; they are not areas any piece of software may connect to freely. For that reason we recommend that these transactions stay in your existing system, and we position the layer we build around them rather than in their place. We research what is possible at the start of the project, specific to your organisation and your current vendor, and we tell you in writing. We do not make promises based on guesswork, because here a promise that cannot be kept means not just a project delay but a real problem on the billing and regulatory side. The same cautious approach applies to diagnosis and clinical decisions: this layer does not produce medical decisions and does not stand in for the clinician's judgement.
What remains is a wide area, and it determines the organisation's operating performance directly. The layer we build reads the data it needs from the main system, holds the data it produces on its own side, and matches the two at patient record level. The connection method is determined by what your vendor permits: HL7 messaging, a FHIR interface, read-only database access or regular file transfer. Honesty is needed here: the timeline of these projects usually depends not on us but on how quickly your existing vendor responds on integration. We mark that in the plan as a separate dependency; we do not reduce it to a single date and promise it. If integration turns out to be impossible altogether, we would rather narrow the scope than build a project on a connection that does not exist.
