Automated Clinical Coding: The AI-based solution to address the critical shortage of clinical coders- Innovation Blog | Deloitte Australia has been saved
Limited functionality available
Every year, thousands of clinical coders sit down and painstakingly read through countless pages of patient notes. The purpose of this arduous task? To convert the raw data into specific diagnoses and procedures, defined by national and international standards, and assign corresponding codes to these. These codes indicate the precise nature of the treatment carried out, and can be used to inform a number of subsequent operational steps, including medical billing, health resource allocation, clinical research, and many more. But what if this critical yet laborious process could be automated?
To help make the vision of accelerated medical translation a reality, Deloitte has been working on developing an AI-based clinical coding solution that can analyse medical notes and accurately determine the relevant clinical codes. Megan Miranda sits down with Deloitte Director Duncan Hancox to learn more about this innovative solution and the broad potential of the technology behind it.
Megan: Tell me a bit about the AI-based clinical coding solution. How does it work?
Duncan: Broadly, the coding solution is an automated tool which works by aggregating the multiple clinical data sources relating to a patient episode (such as pathology tests, operating notes, discharge summary), then ingesting and cleansing the raw data. It then structures this data (if it is not already in a structured format) by identifying relevant medical terminology, using named entity recognition techniques, and subsequently applies algorithms to predict appropriate clinical codes, which can be validated by the hospital’s coding team.
The solution has been developed using publicly available dummy data. Over time, feedback from coders, and machine learning techniques, will help it refine its accuracy automatically, and adapt to new coding conventions, diagnoses and treatments.
Megan: How does automated clinical coding help realise hospital strategy?
Duncan: Automated clinical coding helps support hospital strategy in multiple ways. Firstly, it has the potential to improve operational efficiency by converting patient notes from diverse sources (and in various formats) into clinical codes in a consistent way, reducing the work effort for clinical coders and improving accuracy and consistency. This does not mean that manual coders are no longer needed, of course. The solution can take over low-complexity coding and high volume coding tasks, leaving coders to focus on the more challenging patient cases. This can also free up coders to work closely with clinicians to support them in developing accurate clinical notes at source - for example helping with the identification and recording of secondary diagnoses, and enabling coders to improve their efficiency and maximise value. Coder shortages also mean many hospitals have significant coding backlogs - automating the clinical coding process could help to reduce these backlogs.
Furthermore, the insights from structured, consolidated, comprehensive patient data provided by the solution support better service planning to inform funding discussions for public hospitals, and more efficient (and accurate) billing for private patients.
Megan: What applications do you see for this technology in the horizon?
Duncan: The base technology of analysing clinical data has numerous use cases. Whilst more accurate billing and mitigating the shortage of clinical coders may be the initial opportunities, further down the line I can see the technology having a great impact when applied during patient episodes to help standardise care and improve patient outcomes. Patient notes could be analysed in real time to identify trends and correlations that could trigger proactive care interventions, and help support the deployment of established and emerging good practice as new research and data comes to light.
While the automated coding solution is still in its development phase, it is an exciting step in providing impactful innovation to hospitals using the latest artificial intelligence technology. The insights gained from the AI-based solution can greatly improve operational efficiency, service planning and could potentially be used to uplift patient outcomes and consistency of care. This would mean a more positive experience for both patients and clinicians, and who wouldn’t want that?
