Abstract

This white paper explores the critical roles of structured and unstructured data within healthcare workflows and the unique challenges they present. The paper delves into the complexities of integrating workflows beyond the confines of Electronic Health Records (EHR) systems, focusing on those being managed in less controlled environments. The paper highlights the essential steps to convert unreadable document images, like fax documents, into structured data suitable for EHR integration. Recognizing that healthcare leaders face multiple solutions, each with its own budget, time, and outcome considerations, this paper provides a comprehensive overview of various implementation paths to guide informed decision-making. 

The Paradox of innovation in healthcare

Healthcare innovation has seen remarkable advancements, from CRISPR’s contribution to preventing more than 18 million hospitalizations and more than three million COVID deaths to 3D bioprinting skeletal muscles and bones.. 

The same level of innovation far from exists on the administrative side of healthcare.  Inefficient, outdated processes hold up the clinical, front-office, and back-office teams. While patients gaze at their provider’s ability to sail through countless screens of medical history, diagnoses, medications, and treatment plans, few understand that a vast and critical dimension of their healthcare information is tied together with little more than toner and paper.  Those same patients also question how some of their lab results appear on their app within hours while other information takes days or weeks to appear, if at all. The answer is unstructured data.  

Digital data in healthcare originate from a wide range of sources, from structured clinical data, such as laboratory test results or patient-reported outcome measures, to unstructured data, such as free text data, collected within or outside of a clinical setting. This wealth of [unstructured] data holds great potential to advance health research, prevention, and patient care delivery. However, over 80% of digital data in healthcare is [only] available as unstructured data.

Unstructured data exists in many forms, including Medical images, faxed documents (including faxed versions of structured data), scanned document images, text files, and audio recordings from speech therapy sessions. None of these data types are easily integrated into the Electronic Health Records system (EHR), the provider’s single source of truth.  Unstructured data also requires extensive processing and manual intervention to be helpful, leading to inefficiencies and high costs. “80% of medical data remains unstructured and untapped after it is created”​​. Of all the unstructured data types, fax documents and their propensity to appear in low-quality, hardcopy forms offer one of the most significant interoperability challenges. This challenge also provides the greatest payoff in unifying patient information, given that 75% of healthcare communication is transmitted via fax

Healthcare Workflows and the EHR

Effective document workflows are the backbone of every healthcare organization’s smooth operation. In an ideal world, every workflow is meticulously planned, flawlessly executed, and ready to adjust in flight. However, as we will cover later in this section, not all workflows are created equally. Processes executed inside the EHR  look and operate entirely differently from those that are not. 

The most problematic workflows are frequently unplanned, emerging when existing information systems cannot handle unstructured data. These workflows were born out of necessity so teams could finish their work. While these workflows can act as a stop-gap, providing a common understanding of how the team should collectively execute a process, they also introduce a new range of issues. 

Healthcare Workflow Types

This section of the white paper has been organized into three primary “buckets” to help delineate the range of healthcare workflows.

Unstructured Data and The EHR

While integrating unstructured fax data into EHRs brings substantial benefits, the process is complex and fraught with challenges. These hurdles stem from the inherent complexities of unstructured data, the limitations of current EHR systems, and the variability in data quality, format, and quality control. Here’s a breakdown of the critical obstacles healthcare organizations face.

Optical Character Recognition

Optical Character Recognition (OCR) is a technology that converts documents, such as scanned paper documents, PDFs, or images, into editable and searchable data. OCR scans document images, recognizes the text, and converts it into machine-readable text. This enhances accessibility for visually impaired users, improves searchability by allowing text indexing, streamlines data entry through automatic data extraction, and facilitates integration with digital systems like electronic health records (EHRs). In healthcare, OCR enables digitizing faxed patient records and other medical documents.

Challenges with OCR and Poor Document Quality 

Low-Quality Images: Fax machines often produce low-resolution images, leading to pixelation and poor text definition, significantly hampering OCR accuracy. High-resolution scanning and image upscaling can mitigate this issue, but low-quality images are low-quality, and additive restoration only goes so far. These documents will still require substantial manual review and data input.

Skewed Documents: Documents fed into fax machines at an angle result in skewed images, causing OCR algorithms to misinterpret characters or entire words. Deskewing algorithms and alignment tools can correct the orientation of the text, but skewed documents may still cause misclassification and incorrect data extraction. 

Inconsistent Lighting and Contrast: Faxed documents often suffer uneven lighting, appearing too dark or too light, which obscures characters and affects OCR accuracy. Lighting issues are noticeably more prevalent in documents sent from traditional fax machines than fax documents sent directly from a digital source using print-to-fax or email-to-fax technologies. Contrast enhancement techniques, including histogram equalization, can normalize lighting, but inconsistent contrast requires extensive manual verification. Inconsistent lighting is a problem in around 25% of faxed documents, impacting readability.

Noise and Artifacts: Noise and artifacts, such as lines, speckles, or smudges, interfere with character recognition. Noise reduction algorithms and morphological operations can clean up the image, but noise still degrades OCR accuracy, requiring manual corrections. 

Document Damage: Fax transmission can damage documents, resulting in missing or distorted sections that OCR struggles to process accurately. Inpainting algorithms and patch-based restoration can reconstruct damaged areas, but document damage still leads to incomplete data extraction. 

Variations in Font and Text Style: Faxed documents often contain text in various fonts and styles, including bold, italic, and underlined text, confusing OCR algorithms optimized for standard fonts. Training OCR models on diverse datasets and using adaptive recognition techniques can improve accuracy, but varied text styles still complicate data extraction. 

Fax Transmission Distortions: Transmission can introduce distortions such as stretching or compression of text and images, disrupting accurate OCR processing. Geometric correction algorithms and affine transformations can restore original proportions, but transmission distortions require additional manual correction. 

Document Annotation: Even in pristine environments, faxed documents can still suffer from readability issues when handwritten notes obscure the underlying text. In most cases, the remedy simply involves confiscating the perpetrators’ pens. 

The level of accuracy at this stage will directly impact further stages in the process. Some human oversight will always be required to manually handle exceptions and make calls on accuracy when OCR confidence scores are questionable. Examining identified readability issues at scale is vital to prevent processing bottlenecks. 

Document Classification 

Document Classification is the process of evaluating a document to determine “what type it is” so it can be routed to the correct workflow, application, or user. Generative pre-trained transformers (aka ChatGPT et al.) make seemingly quick work of this type of task with caveats such as: 

“ChatGPT can make mistakes. Check important info.” (OpenAI)

These caveats do not translate to the healthcare environment. Accurate document classification is the bedrock upon which the entire data integration process into EHRs rests. The complexity of this task cannot be understated, as it involves distinguishing between various types of documents, each with its unique structure (or variety of structures) and content. This demands a robust AI model (or multiple models), and models continuously trained on a vast dataset, encompassing every conceivable variation in document format and content. The role of human experts in this domain is pivotal. Annotated datasets curated by humans form the backbone of all training phases, and continuous human intervention is necessary for quality assurance. The feedback loop created by human reviewers is indispensable for refining the model, ensuring it adapts to new document types and maintains high accuracy.

Contextual Understanding in Classification

Moving beyond mere text recognition, the contextual understanding of documents is a nuanced challenge that significantly impacts classification accuracy. AI systems must recognize textual content and understand its context within the document. This involves discerning the relevance of different sections, such as headers, footers, and body text, and categorizing documents based on this contextual understanding.

A Highly Simplified Document Classification Example:

There are two documents relating to the same patient. One is a claims submission; the other is a patient referral. 

Document 1

1. Patient Name: John Doe
2. Date of Birth: 01/15/1980
3. Insurance ID: 123456789
4. Date of Service: 06/01/2024
5. Total Charges: $200.00
6. Provider: Dr. Smith
7. Procedure Code: 99213
8. Diagnosis Code: I10 (Hypertension)

Document 2

1. Patient Name: John Doe
2. Date of Birth: 01/15/1980
3. Referring Physician: Dr. Smith
4. Referred To: Dr. Johnson, Cardiologist
5. Reason for Referral: Hypertension management and consultation
6. Appointment Date: 06/15/2024
7. Special Instructions: Bring previous medical records

Contextual Understanding at work

Step 1: Looking for Key Clues

Document 1:

• Insurance ID: This is a big clue because insurance information is usually needed for claims.
• Total Charges: Mentioning money and charges strongly suggests this document is about billing or claims.
• Procedure and Diagnosis Code: The codes explain the procedures that are essential for claims processing.

Document 2:

• Referring Physician and Referred To: These lines indicate that one doctor is sending the patient to another doctor, which is typical in referral documents.
• Reason for Referral: Explaining why the patient is being referred is another clue that this document is a referral.
• Special Instructions: Giving instructions for an upcoming appointment is common in referrals.

Step 2: Analysis

• Document 1: The presence of insurance details, total charges, and specific medical codes used for billing makes it clear that this document concerns submitting a claim for insurance to cover the costs.
• Document 2: The information about one doctor referring the patient to another specialist, the reason for the referral, and instructions for the appointment all point to this being a referral document.

Challenges with Classification and Poor Sample Data

Inconsistent Labeling: Conflicting labels for similar documents leads to misclassification. For example, some claims documents are labeled as “Billing Forms” and others as “Insurance Claims.”

Insufficient Variety: Limited examples cause the model to overfit and fail to generalize. For example, the model only sees claims documents from one hospital, so it can’t recognize different layouts from another hospital.

Inclusion of Irrelevant Features: The model learns from irrelevant features, causing misclassification when these features are present. For example, the model associates a specific logo with claims documents, leading to errors if other documents have the same logo.

Poor Quality Data: Errors and noise in data result in incorrect associations and reduced prediction confidence. For example, if training data has frequent typos, the model might not recognize key terms correctly.

Biased Data: Bias towards a specific style results in poor performance on different document styles. For example, if all training data is from a single clinic, the model may struggle with documents from other clinics.

In short, manual document review is still a far better option than poorly implemented document classification, which delivers automated misclassification.

Data Extraction

Data Extraction is essential for integrating data from various sources into structured formats for further analysis and decision-making. While healthcare documents are more challenging than those in more standardized industries like finance, modern data extraction methods have come a long way from rubber-banding.  

How Data Extraction Works

Contextual Understanding: Much like Document Classification, advanced data extraction uses NLP Contextual Understanding, distinguishing between headers, footers, body text, and other elements to accurately identify the relevant information. For example, NLP can differentiate the main body of a patient’s medical history from the section listing their current medications.

Entity Recognition: Identifying and categorizing key entities (e.g., names, dates, medical codes) within the text. For example, the system can recognize and label “John Doe,” “01/15/1980,” and “I10 (Hypertension)” as a patient’s name, date of birth, and diagnosis code, respectively.

Data Formatting involves extracting the identified entities and converting them into a structured format. For instance, after recognizing entities in a medical claim form, the system extracts them into a structured database with fields for patient name, date of birth, procedure codes, and costs.

Data Validation: Ensuring the accuracy and completeness of the extracted data through various validation techniques, such as cross-referencing extracted patient names and dates of birth with an existing database to ensure no discrepancies.

Difference from Legacy Extraction Methods

When used with healthcare documents, legacy data extraction methods were notoriously fragile and inaccurate,  relying on predefined templates and fixed positions of data points. These techniques made them inflexible and unable to handle variations in document layouts. They often failed with inconsistent or complex structures and required significant manual adjustments.  In contrast, AI data extraction methods are flexible, handling various document formats and structures and using NLP for contextual understanding, which improves accuracy in identifying relevant data. Additionally, AI methods are scalable, efficiently processing large volumes of diverse documents with far higher accuracy and without requiring continual manual intervention.

Accurate and efficient data extraction requires much of the same care and feeding as document classification. Ideally, this means: 

• High-quality, readable documents
• An extensive, representative, up-to-date data set to train on
• Consistent training via human feedback
