Natural Language Processing (NLP) is a technology that helps computers understand human language in writing and speech. In healthcare, NLP works with unorganized data—data not stored in clear formats like tables—to find useful information. This is important because about 80% of healthcare data is unorganized, found in clinical notes, discharge summaries, and other written documents.
For managing clinical trials and discovering drugs, NLP helps make sense of this unorganized data. By reading through thousands or even millions of pages of clinical papers, NLP helps researchers and doctors find patients who can join trials, study patient results, and check that important documents are correct and consistent.
One big challenge in clinical trials is finding and keeping enough eligible participants. Studies show that about 85% of trials fail because they do not get enough participants. This slows down or ends the trial process. NLP helps by finding patients who fit the trial criteria from unstructured electronic health records and clinical notes.
For example, Tempus uses NLP-based AI to scan patient records for certain health conditions. In heart care, their methods have found patients with serious heart valve problems who were missed before. This helps get more patients into trials faster. It also saves healthcare workers time when searching through records.
NLP speeds up the management of trial data by digitizing and summarizing large amounts of clinical information. It stops delays caused by manual reviews by quickly spotting trends and feelings in participant feedback. Tools that analyze sentiment find how patients feel about their care and experiences, which helps trial managers understand better.
In the U.S., where clinical trials include many different types of patients and complex rules, automation like NLP is very useful. NLP tools help trial managers sort healthcare professionals and patient groups based on data from unorganized records. This helps them choose the right sites and people for trials, making the trials run more smoothly and staying within legal rules.
Finding new drugs takes a long time and costs a lot. AI and NLP help by managing and studying big sets of clinical data and research documents. They find patterns and predict how well drugs might work and their possible side effects.
Companies like Pfizer use AI and NLP to automate making regulatory documents and to keep medical terms consistent. Boris Braylyan, Pfizer’s Vice President and Head of Information Management, says NLP makes sure the same words are used across millions of pages of reports. This reduces mistakes and helps communication inside the company and with regulators.
NLP also helps decision-making by looking at trial data to find markers that predict how patients will respond to medicines. AI looks at many types of data, including genes and molecules, to find good drug candidates faster. This lets researchers focus on promising drugs sooner, improving the drug development process.
Another important use is automating regulatory submissions. AI can guess what questions regulators might ask and prepare answers ahead of time. This cuts delays in drug approvals, which is very useful in the competitive drug industry.
Apart from NLP, AI can automate routine and paperwork tasks. This lowers errors and lets clinical and admin staff focus more on patients and planning. Automation makes tasks like data entry, claims processing, appointment scheduling, and document transcription easier.
Companies such as Microsoft have tools like Dragon Copilot, which helps doctors by drafting referral letters and visit summaries using natural language processing. This cuts down on paperwork that often causes burnout among healthcare workers.
In clinical trials, AI-driven automation handles generating documents, quality checks, data validation, and following trial participants in real time. This reduces manual mistakes and helps meet strict regulatory rules like those by the U.S. Food and Drug Administration (FDA).
AI-powered virtual assistants and chatbots also help by doing early interviews, gathering medical histories, and reminding patients about appointments or medicines. This improves communication and helps patients follow trial rules better.
Using AI and NLP in health research must follow strong privacy and security rules. The Health Insurance Portability and Accountability Act (HIPAA) sets national rules to protect patient data in the U.S. All AI technology must follow these rules.
Good NLP and AI systems use strong data encryption, control who can access data, and have regular security checks to keep patient information safe. These steps help health organizations balance new technologies with protecting patient privacy and building trust with patients and regulators.
The AI market in healthcare was worth $11 billion in 2021 and is expected to grow to almost $187 billion by 2030. NLP technologies are a key part of this growth. The global NLP market in healthcare is predicted to grow from $2.7 billion in 2023 to $11.8 billion by 2028.
A 2025 survey by the American Medical Association found that 66% of U.S. doctors already use AI tools in patient care. Also, 68% believe AI has a positive impact on patient health. These numbers show that more doctors accept and use AI in regulated healthcare settings.
Medical practice administrators and IT managers in clinical trial sites or healthcare must understand the role of NLP and AI for planning technology use. Challenges include making sure AI works well with Electronic Health Record (EHR) systems, training staff, and continuous system checks.
AI tools are often available through cloud services, which offer flexible solutions that do not need big upfront costs. This works well for smaller healthcare providers who want to join clinical trials or improve their operations without spending too much money.
Investing in AI needs partnerships with reliable vendors, following legal rules, and constant system monitoring to make sure data is accurate and patients stay safe.
AI automation also helps with money management by speeding up claims processing, cutting down claim denials, and reducing manual errors in coding. This helps clinical trial sites and healthcare practices stay financially stable while managing patients.
As AI and NLP improve, they will have a bigger impact on healthcare research and managing clinical trials. AI-assisted remote monitoring and digital data collection can help make decentralized clinical trials easier for patients to join.
Combining different types of data like images, genetic info, and real-world data will improve personalized medicine. This will offer treatments that fit individual patient needs better.
Regulatory agencies like the FDA keep working on rules for safe and fair AI use. They aim to balance technology progress with patient safety and responsibility.
In summary, NLP and AI help make clinical trial work easier and speed up drug discovery in the U.S. By automating data review, improving trial enrollment, making documents more accurate, and supporting regulatory rules, these tools help medical managers and IT staff run clinical operations and research well. Their use is growing with more investment and doctor acceptance, leading to better healthcare efficiency and patient results.
