Methods The original Pinnacle system was modified by adding a button of"Search Patient" in the window of"Patient Select" to call a self-built window of"Search Patient by MRN or Name". After inputting the patient′s Medical Record Number or Name, a self-built script file was called to quickly find and locate the patient′s record. Results The patient′s MRN or Name was input in the window of"Search Patient by MRN or Name",and then input"Enter" or clicked the button of Search to rapidly identify the patient and enhance the search efficiency. Conclusion The openness and script of the Pinnacle system can be utilized to modify and improve and supplement the existing func-tions.
