Legibility of doctor's signatures: novel approaches to improving an age-old problem

In today's medico-legal environment, the importance of identification of the authors of notes in patient medical charts cannot be overemphasized. We evaluated three different techniques of signing patient notes, over a one month period, in order to determine which technique was the most effective in identifying the author of the note. Surgical NCHDs in our hospital were divided into three groups. Group 1 was asked to sign the notes as they normally would. Group 2 was asked to print their name in block capitals after their signature and Group 3 was given pens with a personal self inking stamp to be used in addition to signing the notes. The number of signatures in all the charts, compliance with the assigned technique and the legibility of signatures were calculated.

in Group 1, all NCHDs signed their name when writing notes (100% compliance), however the NCHD's signature was identified only 37% of the time. In Groups 2 (who signed in block capitals) and Group 3 (who used the pen with personalised stamp) the author was identifiable 100% of the time when the respective signing method was used. Using the pen with personalised self inking stamp was significantly more popular (77% compliance) compared to signing in block capitals (46% compliance). In conclusion the pen, with personalised self inking stamp, provides a fast and effective means to clarify signatures of NCHD's documentation, which is not only important in a day to day patient management, but is essential from a medico-legal stand point.
