                The purpose of this research was to monitor the incidence of Gestational Diabetes Mellitus (GDM) using adjusted p control charts. The research were used adjusted p control charts to monitor the incidence of GDM based on secondary data from the years 2011 through 2016 from the Sakonnakorn Hospital.

         The results indicated thatconcerning the GDM incidences monitored by the adjusted p control chart, 1) there was only one point, November 2015, detected to be out-of-control; 2) investigating the relevant causes, by applying the Pareto 80/20 rule, there were three particularly salient GDM risk factors, locating almost 80 percent of the cases i.e., 30 years or more of gestation, obesity before pregnancy, and overweight before pregnancy; 3) after adjusting new control limits, all points lay within the action limits which indicated that the process was under control.
