The products of such documentation, conventionally called “notes,” serve many purposes: reminding the note author of what they did, communicating to other providers both in the present and the future, justifying a level of service provided and fee charged, defending decisions in case of malpractice accusations, providing data for research and quality improvement, and even communicating with patients as in OpenNotes 2) 3) 4).
The last major paradigm shift in documentation occurred in 1968 when Dr. Larry Weed proposed the problem-oriented medical record 5).
Clinical documentation is usually stored in an unstructured format in electronic health records (EHR). Processing the information is inconvenient and time-consuming and should be enhanced by computer systems. In this paper, a rule-based method is introduced that identifies adverse events documented in the EHR that occurred during treatment. For this purpose, clinical documents are transformed into a semantic structure from which adverse events are extracted. The method is evaluated in a user study with neurosurgeons. In comparison to a bag of word classification using support vector machines, our approach achieved comparably good results of 65% recall and 78% precision. In conclusion, the rule-based method generates promising results that can support physicians' decision making. Because of the structured format the data can be reused for other purposes as well 7).
