Healthcare workers in the United States face a growing problem every day: dealing with large amounts of patient data. Most of this data is unstructured, meaning it does not follow a set format like numbers in a spreadsheet or neatly organized text. Instead, it includes things like doctors’ notes, clinical stories, discharge summaries, audio recordings, medical images, and even patient feedback.
While this unstructured data contains important information for patient care, it is hard for traditional healthcare systems to process, analyze, and use well. This problem has opened the door to new technologies, especially Natural Language Processing (NLP). NLP is starting to change how doctors, healthcare managers, and hospital IT staff work with patient records and medical data.
About 80 percent of healthcare data in the United States is unstructured. This includes doctor notes typed into Electronic Health Records (EHRs), imaging reports, pathology tests, and audio files from patient visits. Unlike structured data (like patient age or lab results), unstructured data is free-form and different every time. This makes it hard for computers to understand using regular data methods.
Healthcare workers often get frustrated by this. Doctors, nurses, and medical coders spend many hours typing notes and information that current software cannot easily analyze. This leads to wasted time and more work, a problem known as “EHR burnout.” Research shows that reviewing and extracting clinical information from free-text records takes a long time, costs a lot, and often has mistakes. For example, going through 100 patient records by hand can take medical coders or researchers five to six hours or more depending on the data.
From the management side, this unstructured data is not used as much as it should be. Healthcare systems do not have good tools to pull out important details hidden in these notes. Important clinical information can be missed during the first review, affecting patient diagnosis, treatment, and coding accuracy. For example, wrong or missing codes for patient conditions can cause billing errors and problems with Medicare payments.
Natural Language Processing (NLP) is a type of artificial intelligence that helps computers understand and analyze human language in text and speech. In healthcare, NLP uses machine learning and other methods to turn unstructured data into organized, usable information.
With NLP, healthcare groups can automatically pull out key clinical details from doctor notes, discharge papers, and other texts faster and more accurately. This cuts the time to review records from weeks or months down to seconds.
NLP also makes medical records more accurate by finding conditions that doctors might have missed or coded wrong. It can handle tricky parts like negation, which means understanding if a patient has or does not have a symptom or condition. For example, if a note says “no evidence of pneumonia,” NLP knows not to mark the patient as having pneumonia.
This technology helps create better patient profiles, which leads to improved diagnosis, risk assessment, and personalized treatments. Drug companies and researchers also use NLP to check clinical trial data, lab results, and medical papers to find patterns that can speed up drug discovery.
The AssistMED project in Poland shows how NLP can work well. It automatically analyzed over 10,700 heart disease discharge reports, pulling out diagnoses, medication details, and test results with almost perfect accuracy like a person would. This shows the potential for using NLP widely in the United States, where heart care faces similar data challenges.
Even though NLP looks helpful, using it in healthcare brings some issues. First, patient privacy and following rules like HIPAA are very important. NLP systems must use strong safety measures to stop data leaks and protect privacy.
Another problem is fitting NLP into existing healthcare systems, especially EHR platforms, which differ a lot between hospitals and clinics. This can slow down adoption and cause problems in daily work.
Early NLP models had trouble with accuracy because medical language is complex and full of abbreviations. But newer methods using deep learning and large language models have made NLP more reliable, especially when trained on big healthcare data sets.
To build trust, NLP tools need to be clear about how they make decisions and be tested in real clinical settings. Healthcare managers should see NLP as tools to help doctors, not replace them, so that humans still have control.
AI technologies, including NLP, do more than just clinical notes. They also automate many healthcare tasks. Medical practice managers and IT staff have access to AI tools that automate phone systems, scheduling, claims handling, and patient messages.
Companies like Simbo AI focus on automating front-office phone services. AI answering systems reduce staff workload and make patient calls smoother. They handle appointment bookings, answer common questions, and route calls to the right place, improving efficiency and patient experience.
Robotic Process Automation (RPA), often powered by AI and NLP, helps automate repetitive office tasks. Healthcare leaders say up to 40% of routine tasks can be automated, freeing staff to focus more on patient care.
Workflow automation also helps the money side of healthcare by speeding up insurance claim processing and cutting errors. Some RPA systems have eliminated up to 70% of repetitive tasks in claims work and shortened turnaround times by as much as 85%.
AI chatbots powered by NLP improve patient engagement by offering 24/7 health info, checking symptoms, and reminding patients about their medicines. The chatbot market in healthcare is expected to reach nearly $950 billion by 2030, showing more people are using these tools.
Telehealth increasingly uses AI for remote patient monitoring. Technologies like computer vision and machine learning check vital signs from video or audio. This lets doctors watch patients closely outside the hospital and notice problems earlier.
In the United States, using NLP fits with a wider focus on data-based healthcare improvements and making health systems work better together. The American healthcare system is very complex and regulated. Technologies like NLP help manage large amounts of data and support value-based care.
Big tech companies such as IBM Watson, Google Cloud Healthcare NLP API, Microsoft, and Epic Systems provide tools that fit well with existing EHR systems and can grow with practices of all sizes.
The healthcare NLP market in the U.S. is expected to grow quickly—from about $1.44 billion in 2024 to nearly $14.7 billion by 2034—showing how important this digital change is.
Also, federal programs focus on sharing health data and protecting patient privacy. This helps make it easier to use AI-powered NLP tools while following the rules. Laws like the 21st Century Cures Act encourage sharing health info among providers, and NLP helps make unstructured data usable.
Handling unstructured data is a big challenge in healthcare management across the United States. It affects clinical work, patient care, and finances. Natural Language Processing offers ways to turn messy clinical notes and documents into useful information that improves diagnosis, treatment, coding accuracy, and efficiency.
Healthcare providers that use NLP as part of a digital upgrade are likely to see better satisfaction among doctors, better patient outcomes, and smoother administration. Combining NLP with AI automation like phone systems and robotic automation helps healthcare organizations use their resources better.
As healthcare technology keeps changing, using NLP and AI tools to improve workflows will be important for healthcare managers, owners, and IT staff who want to give care that is accurate, efficient, and focused on patients.
