Pain prediction



Pain is a common but significant problem that is considered a high priority area of care. Although there are many pain assessment scales that can be applied to patients who can communicate, either verbally or non-verbally, pain assessment for minimally responsive patients is limited. In this preliminary work, we developed a novel approach for assessing pain in such patients using a principal component analysis (PCA)-based local detector. Our algorithm produce a single index to indicate the increase in pain level based on unsynchronized, sparse and noisy time series data collected from electronic flowsheets.
