What's Happening?
Researchers at the University of New Mexico School of Medicine have conducted a study analyzing electronic health records of over 1.3 million patients from the Veterans Health Administration (VHA). The study highlights a significant gap in how health systems
track self-harm, revealing that diagnosis codes capture only about one-fourth of clinically documented self-harm history. The research, published in the Journal of Medical Internet Research, utilized a machine learning method called PULSNAR to estimate the presence of self-harm history that is not visible through diagnosis codes. The study found that documented self-harm was present in about 7.9% of patients, compared to the 1.85% visible through diagnosis codes alone. This gap is crucial as it affects clinical awareness and planning for mental health services.
Why It's Important?
The findings of this study are significant for the U.S. healthcare system, particularly in the context of mental health services for veterans. By identifying the under-recording of self-harm in medical records, the research underscores the need for improved measurement and tracking methods. This can lead to better planning and allocation of mental health resources, ensuring that veterans receive the necessary care and support. The study also highlights the potential of machine learning tools to enhance the visibility of critical health information, which can improve clinical decision-making and patient outcomes. As self-harm is a predictor of future suicide risk, addressing these gaps is vital for effective mental health interventions.
What's Next?
The research team suggests that the PULSNAR method could complement existing VHA mental health and suicide-prevention efforts by providing a scalable way to measure under-recorded conditions. While the method is currently a research tool, further development could enable its integration into clinical care, helping health systems better estimate mental health conditions and identify records that require closer review. The study is part of a broader research program aimed at detecting under-recorded conditions in medical data, with ongoing work extending to other mental health issues such as PTSD and depression.
