Hospitals run on documents. Medical histories, lab results, discharge summaries – every patient leaves behind a paper trail. The problem? Most of it still sits in unstructured formats. You can scan it, sure. But unless someone reads and types the data into a system, it’s practically invisible to modern software. That’s where Optical Character Recognition, or OCR, comes in.
We sat down with Nikolay Stefanov, BGO’s very own specialist in intelligent document processing, who’s spent years developing OCR solutions for healthcare. He explains OCR not as a buzzword but as a powerful tool that makes medical data visible, usable, and trustworthy.
Let’s start with definitions. OCR is a technology that converts printed or handwritten text into machine-readable data, which in turn allows healthcare organizations to digitally extract patient information from medical records with high accuracy.
But the power of OCR software doesn’t stop at text recognition. Stefanov’s work focuses on extracting real meaning from complex, messy inputs. He puts it simply – one does not just need to recognize the words themselves; rather, they need to understand what’s what-who the patient is, what the diagnosis is, what the doctor prescribed. That’s where intelligent processing comes in.
Over the course of the interview, Stefanov walks us through how OCR reshapes document management in hospitals, why speed and accuracy matter, and how it integrates with systems like Electronic Health Records (EHR). His excitement is contagious-and for good reason. When Optical character recognition in healthcare works right, healthcare gets faster, safer, and smarter.
How OCR transforms document management
Let’s start with the problem: Hospitals are drowning in documents. Most of them don’t follow any single format. Some are printed from older systems, some arrive as faxes, and others are scanned by overworked admin staff. The result? Data gets trapped in PDFs and images, making it impossible to use at scale.
That’s where OCR starts to change the game. Stefanov explains it like this:
“Anything that we use as medical people… all the documentation we use moves to optical character recognition. I would include not only the character, but also all sorts of things related to tables, with information that is in text form… various visualizations, workflow diagrams, decision trees, etc.”
- Nikolay Stefanov
The shift is more than technical – it’s functional. With the right OCR system, hospitals can search, sort, and automate actions based on the content of a document. A discharge summary isn’t just a file anymore- it becomes structured data tied to a patient’s digital record. That means faster handoffs between departments, fewer mistakes, and more time for actual care.
Stefanov gives a simple but powerful example. Everyone knows where their city’s library is – it usually is also very easy to reach. That library contains all the knowledge in the world, but it is inconvenient to access the knowledge there – that knowledge must be digitized to become truly accessible
What are the benefits of OCR in Healthcare?
In the healthcare industry, speed saves lives. But it also saves sanity. When hospitals rely on manual document handling, delays pile up fast-especially when staff have to search through dense files to find one piece of critical information. OCR technology flips that workflow.
Our expert strongly believes that time is one of the most valuable resources in healthcare. He’s witnessed firsthand how OCR in healthcare turns hours of manual searching into seconds of digital retrieval. The impact? Simple, it saves time. Professionals will be able to focus on patients rather than paperwork.
Stefanov highlights three transformative benefits of OCR:
- Instant access to large volumes of critical data
When information is digitized, we’re empowering modern technologies for fast searches. We have better patient record managment. No more frantic searches through physical archives when a patient crashes in the ER. Vital signs, medication lists, and allergy warnings appear with a keystroke. This all results in better patient care and improved accessibility.
- Error-proof patient records
Stefanov highlights how OCR software can even reduce the risk of human error. Misplaced decimal points in lab results or misread handwritten notes become relics of the past. The error impact can be extremely severe, in healthcare you cannot be wrong, as lives are at stake.
- Transparency builds trust
Having the information in a convenient form allows physicians to show patients how they reached conclusions. This demystifies medical decisions, helping patients understand their care rather than blindly trusting with the stereotypical idea “the doc told me one thing.”
- Reduced costs and improved efficiency
Naturally, cutting tedious processes like transcribing information results in a better workflow. A better workflow in turn, means reduced costs for operations and overall improved efficiency of team members.
- Compliance
Digitizing through OCR software has the nice side benefit of helping organizations comply with both privacy and security regulations, as it stores sensitive patient data more securely than it would be on a sheet of paper.
The hidden advantage
Stefanov also reveals another unexpected benefit: combating clinician burnout. In radiology right now, a lot of technologies lead to burnout because specialists don’t trust them. But properly implemented OCR does the opposite – it becomes like a trainee that gains credibility by consistently delivering accurate, instant data.
The clock is always ticking in healthcare. Ultimately, even the clumsiest system is better because it will not get tired. Unlike humans working late shifts, digital systems maintain perfect accuracy whether it’s 9 AM or 3 AM.
Real-World Use Cases of OCR in Healthcare
Healthcare runs on paperwork. From scribbled prescription pads to multi-page lab reports, medical facilities drown in documents every day.
“Everything you have seen on paper in a hospital is actually a document. Prescriptions, patient histories, lab results – it’s all fair game for OCR.”
- Nikolay Stefanov
For us to understand the sheer value of OCR tech, we must know what kind of paperwork the healthcare industry has to struggle with every day. Medical records come in staggering variety:
- Structured forms
Insurance claim sheets with checkboxes, vaccination cards with pre-printed fields – these should be easy, right? Not so fast. Will it be able to detect that we have actually written the diagnosis for the right lung in the box for the left one? Even “simple” forms become complex when human error enters the equation. - Free-Text narratives
Doctor’s notes present the ultimate test. OCR must parse rambling clinical narratives where critical details hide in casual phrasing. A system might need to identify that “PT c/o RLQ pain x 2 days” translates to “patient complains of right lower quadrant pain for two days.” - Hybrid documents
The worst offenders combine structure and free text. Take discharge summaries: pre-printed headers with handwritten vitals, typed paragraphs with margin notes, and signature blocks that might contain urgent addendums. The better OCR recreates what we’ve tried to put as a division of information in the paper document when it digitizes it, the better it is.
“Will OCR get confused that the entry number is handwritten at the bottom because we didn’t have enough space for the doctor’s name at the top?…f it’s deriving diagnoses… you’re actually changing the diagnosis.”
- Nikolay Stefanov
Medical staff constantly improvise document layouts. The stakes couldn’t be higher. As Stefanov warns, A single misread decimal point in lab values or a flipped digit in a medication dose could prove catastrophic. Luckily, OCR can handle all that! Modern Optical character recognition technology recognizes handwriting, can preserve layouts and understand the context while doing so!
Having that functionality in mind, let us look at what exactly OCR brings to the table:
- Digitizing and Archiving Medical Records:
Converts paper-based records into digital formatsa and them accessible for searching and retrieval - Automating Insurance Claims Processing:
That digital information can then also be used in the automation of the process of insurance claims, freeing up staff to focus on other tasks. OCR does data extraction of the relevant info from the insurance claim forms and and speeds up the whole process. Thre result – faster payments and a better revenue cycle. - Supporting Risk Adjustment and Analytics
OCR allows for the extraction of data from medical records for analysis and risk adjustment purposes. This helps healthcare providers identify at-risk patients and tailor care plans accordingly.
OCR has become even more convenient now that it has the ability to segment the different parts of the document. This isn’t just digitization – it’s document intelligence-the ultimate goal – recreating the human understanding of paper documents digitally.
The human factor: How OCR builds trust and transparency
Beyond its technical capabilities, optical character recognition is quietly revolutionizing the patient-provider relationship in profound ways. Nikolay Stefanov offers unexpected insights about how digitizing medical documents impacts healthcare’s most fragile element – human trust.
Demystifying medical decision-making
Stefanov identifies a critical pain point:
“People avoid medical help because… the doctor makes a hypothesis but can’t share the whole backstory in their head…Having the information in a convenient form allows physicians to show patients how they reached conclusions.”
- Nikolay Stefanov
OCR-powered systems address this by creating auditable trails of clinical reasoning. Imagine a patient questioning their diagnosis – instead of defensive explanations, the physician can instantly pull up similar case histories, treatment outcomes, and clinical guidelines that informed their decision. This transparency transforms encounters from blind trust to informed partnership.
The anti-burnout paradox
While many technologies contribute to clinician exhaustion, Stefanov observes OCR has the opposite effect when implemented thoughtfully. He describes how specialists distrust new technologies when they feel like black boxes, but well-designed OCR systems earn confidence like a medical trainee – through transparent reasoning and consistent performance. The key lies in what Stefanov calls “the validation at each little step,” giving clinicians visible quality checkpoints rather than opaque outputs.

Rebalancing the human-machine dynamic
To put it simply – OCR should function like an impartial analyst sitting alongside clinicians. This isn’t about replacing judgment but creating that figure that surfaces overlooked connections. Our expert observes that a fatigued doctor might miss how a patient’s current condition relates to a side event weeks earlier, but the system wouldn’t miss it as a factoid.
Perhaps most profoundly, Stefanov suggests OCR’s ultimate value may lie in restoring medicine’s human core. In an era of squeezed appointment times and clinician burnout, OCR done right doesn’t depersonalize care – it creates space for the conversations that truly matter.
