Trends in public perceptions of electronic health records during early years of meaningful use.
To track consumer perceptions of EHRs during this period, the researchers conducted a national telephone survey annually for 3 consecutive years, from 2011 to 2013, corresponding with the early years of Meaningful Use. They concluded that during the early years of the MU program, exposure to EHRs increased while confidence in the benefits of EHRs and concerns about privacy risks became less marked.

DEEPEN: A negation detection system for clinical text incorporating dependency relation into NegEx.
The researchers developed a negation algorithm called DEEPEN to decrease NegEx’s false positives by taking into account the dependency relationship between negation words and concepts within a sentence using Stanford dependency parser. The evaluation results demonstrate DEEPEN, which incorporates dependency parsing into NegEx, can reduce the number of incorrect negation assignment for patients with positive findings.
