Liked JAMIA: Quantifying clinical narrative redundancy in an electronic record

http://www.ncbi.nlm.nih.gov/pubmed/20064801

Records examined from 100 randomly selected patient admissions.

Documents aligned using a modified version of an established DNA sequence

alignment algorithm (Levenshtein edit distance algorithm). High levels of 

redundancy were observed with successive documents of the 

same type, and across document types.
