The average healthcare provider faces pages upon pages of paperwork to fill out, taking up valuable time they could spend on treating patients. Natural language processing might be the key to reducing this workload and enabling faster workflows in healthcare.
What is Natural Language Processing (NLP)?
Natural Language Processing (NLP) is the field of software that enables computers to listen and understand spoken and written language the same way that humans do. In the past, NLP software was limited to very basic and formal verbal commands, such as text-to-speech software. More casual and informal language, or anything that falls outside of its pre-programmed expectations, was far too difficult for these programs to handle.
Modern NLP programs rely on computational linguistic techniques, which translate human language into a format that is easier for computers to process. This includes techniques like syntactic and semantic analysis, which help them understand conversational language by looking at the relationships between words in a sentence.
Types of NLP
Like any other piece of technology, NLP software has gone through several different versions over the years.
- Rules-based NLP: These programs were based on if-then decision trees with preprogrammed rules and could only answer in response to very specific prompts. These models were extremely limited and could not scale in terms of capability, which led to them being replaced.
- Statistical NLP: A statistical NLP extracts, classifies, and labels each element of the text or voice data and then assigns a statistical likelihood to each meaning of those elements. These NLP programs rely on machine learning and introduced the technique of “mapping” language elements like words and grammatical rules onto vector representations so that language can be modeled using mathematical methods, making it easier for computers to understand and analyze them.
- Deep learning NLP: Deep learning NLP programs are an evolution of statistical NLPs and rely heavily on the implementation of machine learning and AI neural networks. These networks are designed to mimic how a human mind works, effectively copying a person’s learning ability. By reviewing massive data sets and learning from the patterns within them, a deep learning-based NLP can provide more accurate transcriptions of dialogue.
Applications for NLP in Healthcare
Given the sheer amount of writing and dialogue that takes place during the average appointment as the provider and patient converse, there are multiple areas where NLP software can help.
Clinical Documentation and Management
Healthcare providers must spend hours upon hours filling out forms and filing them away with the appropriate EHR software. Unfortunately, this is a massive timesink that distracts them from focusing on the patient’s needs. With NLP software up and running on their healthcare computer, they can simply take notes or record the appointment and have the NLP program automatically fill out fields in the EHR system. More advanced NLP technology can even identify and correct errors that it finds during transcription, preventing medical errors from ever occurring.
Patient Care and Diagnosis
NLP software’s ability to discern phrases or terms from notes lets it assist clinicians in patient care and diagnosis. For example, the software can detect key symptoms that the patient is experiencing, compare them with other testimonies from other patients, and offer suggestions as to what condition the patient is experiencing. This is especially important in situations like early infection detection, where an early and accurate diagnosis can literally be the difference between life and death.
Big Data Analytics
NLP in healthcare makes analyzing vast amounts of data easier and more efficient, letting providers utilize larger sets of information for things like clinical trial matching and population health management. Healthcare groups can use this information to pair patients with the right trials for their conditions or monitor for patterns in the broader population, such as early pandemic detection.
Benefits of NLP in Healthcare
Implementing NLP software in healthcare processes can bring major benefits for healthcare providers, freeing up time during and after a shift.
Greater Efficiency for Healthcare Providers
The greatest advantage that NLP offers for healthcare is its ability to listen to a conversation between a provider and patient, automatically filling out fields in an EHR as they go. This lets the provider focus entirely on the patient, with only minor amounts of review and editing required afterwards. This reduces the time spent filling out EHRs and spares providers from pajama time, letting them focus on their true calling: treating their patients.
Dialectical Flexibility
Another significant benefit of modern NLP software is that it can sort through various dialects, slang, and grammatical oddities that occur in a typical day-to-day conversation. It can also decipher the imprecise language used by patients who (understandably) don’t know the correct technical terms for their conditions. This places it far ahead of previous generations of speech processing software, which struggled to decipher or transcribe more casual dialogue.
Flexibility Across Written and Audio Notes
AI-powered NLP programs can work off of both written and audio notes, letting providers document their conversations however they prefer and letting the NLP program transcribe afterwards. An NLP program running on a medical AI box PC is the perfect means for doing so.
Challenges for NLP in Healthcare
Like any innovation or new tool, there are obstacles to overcome when using NLP in healthcare. The most important challenges to address when using NLP software in your healthcare practice are:
Specialized Equipment
First and foremost, natural language processing requires specialized software to run, as well as hardware to support it. NLP programs, especially AI-powered versions, require powerful computers to run them alongside EHRs, audio recording software, and other tools. If the provider wants to take audio notes, they will also need effective recording equipment that can clearly pick up the voices of their patients.
Cost
Obviously, any new tool comes with a price tag. Along with licensing NLP software for use, healthcare groups must also consider the price of new computers capable of supporting said software. One way to manage costs for new equipment is by working with an original equipment manufacturer (OEM). An OEM can customize products to the exact specifications of the end-user, ensuring you can get the most out of your purchase without breaking your budget.
Training and Adoption
The final major hurdle to overcome is encouraging its adoption by the actual end-users; in this case, healthcare providers. In this stage, giving providers the time to train and actually familiarize themselves with the new tools. It’s also critical to listen to user feedback during this time, so that you can identify areas of improvement and make deploying the NLP software easier.
