Could deep learning AI be used to screen TIA clinic referral letters? Possibly.

Could deep learning AI be used to screen TIA clinic referral letters? Possibly.

Stroke prevention clinics (TIA or Transient Ischaemic Attack) clinics are an important aspect of urgent care. A TIA is a risk factor for future stroke. Medical treatment needs to be started quickly and surgical options, if indicated, done within 2 weeks. Ensuring that the right case mix is brought to the clinic is a challenge. Came across these two papers on Deep Learning Artificial Neural Networks (AI) for classifying patient histories. This type of efficiency improvement to healthcare may come quite fast especially where the amount of shared high quality data increases and interdisciplinary research takes place.

"Deep learning-based natural language processing, in particular convolutional neural networks, based on medical free-text, may prove effective in prediction of the cause of TIA-like presentations. Future research investigating the role of the application of deep learning-based natural language processing to the automated triaging of clinic referrals in TIA, and potentially other specialty areas, is indicated."

"This pilot study indicated that ANN [Artificial Neural Network] may yield a novel and effective method in risk stratification of TIA and minor stroke. Further studies are warranted for verification and improvement of the current ANN model."
