title: [Optimize visiting sequence and time-interval appointment of re-visiting patients in stomatology].
abstract: OBJECTIVE
  To optimize visiting sequence and time-interval appointment mode to reduce waiting time of re-visiting patients in department of stomatology based on clinical data repository.
  
  
  METHODS
  Waiting time data of re-visiting patients in department of stomatology was collected and divided into 2 groups. A total of 70897 patients from July 2014 to September 2014 were enrolled as experimental group (group year-2014), while 63960 patients from July 2013 to September 2013 were used as control group (group year-2013).Measurement data was compared with two-tailed independent-samples t test using SPSS 22.0 software package.
  
  
  RESULTS
  The waiting time of group year-2014 was 73.65 minutes while it was 106 minutes for group year-2013. P value was 0,which meant the waiting time of group year-2014 was significantly less than group year-2013.
  
  
  CONCLUSIONS
  Optimizing visiting sequence and time-interval appointment mode can reduce the waiting time of re-visiting patients in department of stomatology greatly.
