How can NLP be used in healthcare for medical records?

The healthcare sector is still looking for and implementing workable solutions for physician burnout related to electronic medical records. The American Medical Association states that for every hour they spend with patients, doctors can spend up to two hours in an EHR system. Despite the fact that scribes and medical assistants can be useful in reducing some of the burdens associated with the data entry process, there are still many problems, including a focus on documentation that is more concerned with patient care than billing, information overload, and difficulty navigating a system quickly.

According to the CTO of healthcare artificial intelligence company John Snow Laboratories, “part of the problem with documentation is that we are asking clinicians to document things in a very specific and unnatural way.” According to Talby, there are quality measures to take into account and EHR documentation is frequently written in a particular way for insurance purposes.

Yet, because an EHR system is text-heavy, it may be ideally suited for an automated procedure like natural language processing, a niche area of artificial intelligence that enables computers to comprehend unstructured written or spoken data. Also, the potential for NLP to enhance the usefulness of medical records has sparked a lot of business interest in the healthcare sector.

Microsoft announced the $19.7 billion purchase of cloud and AI software pioneer Nuance earlier this year, signaling the tech behemoth’s growing growth in the healthcare sector. To enable data gathering and the creation of clinical notes, Nuance provides AI solutions that interact with EHRs.

AI-based solutions can provide a means to reduce employee annoyance and enhance time for patient care as healthcare systems continue to look for solutions to the problem of physician burnout brought on by EHRs.

How Does NLP Work? What Is It?

Natural Language Processing (NLP) is an area of Artificial Intelligence (AI) that focuses on interacting with computers and humans through natural language. NLP technology enables computers to understand, interpret, and generate human language, which can be used to improve efficiency, accuracy, and quality in various industries, including healthcare. NLP can help healthcare professionals create more accurate and complete clinical documentation, better communication between healthcare providers, faster and more accurate diagnoses, and better treatment outcomes. 

It can also help in extracting valuable information from EHRs (Electronic Health Records ), identifying trends and patterns in patient data, and analyzing vast amounts of medical data. NLP-powered chatbots and virtual assistants can help patients manage their health better, and can help streamline administrative tasks such as billing and claims processing. Disease Surveillance can help in monitoring and detecting outbreaks of infectious diseases by analyzing social media, news reports, and other sources of information. In this article, we will discuss the current applications of NLP in healthcare and the future opportunities for NLP technology in the field.

The rise of NLP in healthcare can be attributed to several factors:

  1. The digitization of medical records has created a wealth of data that can be analyzed using NLP techniques.
  2. The increasing adoption of electronic health records has made it easier to share data across different healthcare providers and organizations.
  3. More sophisticated NLP algorithms have made it possible to analyze and interpret natural language text data with greater accuracy and efficiency.

Applications of NLP in Healthcare

NLP has many potential applications in healthcare.
Clinical Documentation Improvement

Clinical documentation improvement (CDI) is a process that ensures accurate and complete documentation of patient encounters. Accurate documentation is critical for patient care, billing, and legal compliance. NLP technology can assist in the CDI process by automatically identifying missing or inaccurate information in clinical documentation. For example, NLP can be used to analyze clinical notes and suggest additional diagnoses, procedures, or medications that were not documented. This can improve the accuracy and completeness of clinical documentation, leading to better patient outcomes and more accurate billing.


Medical Coding

Medical coding is the process of translating medical diagnoses and procedures into standardized codes for billing and reimbursement purposes. Accurate medical coding is essential for healthcare organizations to receive proper reimbursement from insurance companies. NLP technology can help automate the medical coding process by identifying relevant diagnoses and procedures from clinical documentation. This can save time and reduce errors, resulting in faster and more accurate billing.


Clinical Decision Support

Clinical decision support (CDS) is a process that provides healthcare professionals with information and guidance to help make clinical decisions. NLP technology can be used to provide CDS by analyzing patient data and suggesting potential diagnoses, treatments, or medications. For example, NLP can analyze clinical notes and lab results to suggest possible diagnoses and treatments for a patient. This can help healthcare professionals make more informed decisions, resulting in better patient outcomes.


Patient Engagement

Patient engagement refers to the involvement of patients in their own healthcare. Engaged patients are more likely to comply with treatment plans, leading to better outcomes and lower healthcare costs. NLP technology can be used to improve patient engagement by analyzing patient feedback and providing personalized recommendations. For example, NLP can analyze patient surveys and suggest personalized wellness plans based on the patient’s responses. This can improve patient satisfaction and lead to better outcomes.


Disease Surveillance and Outbreak Detection

Disease surveillance and outbreak detection are critical components of public health. NLP technology can be used to analyze social media and news articles to identify potential disease outbreaks. For example, NLP can be used to identify keywords and phrases related to illness in social media posts and news articles. This can help public health officials detect outbreaks early and take appropriate measures to prevent the spread of disease.

Potential future opportunities for NLP:

The future of NLP is bright, and there are many exciting opportunities for its application across different industries.
