The finding suggested that the patiens who received the services from high blood pressure Clinic at Maelan Hospital in 2006 and those who received the services from Primary Health Care Unit in 2007 were able to have better control of high blood pressure through the systolic pressure  \< 140 mmHg and the diastolic pressure  \< 90 mmHg with the different statistical significant importance at the level of .05 (t=4.074) (t=2.177) with the increase of normal blood pressure in 2007 systolic pressure  \< 140 mmHg which been increased from 82 patients in 2006 to 108 patients in 2007 (13.7%) and diastolic pressure  \< 90 mmHg which has been increased from 158 patients in 2006 to 160 patients in 2007 (1%) respectively.en-USFaculty of Medicine, Prince of Songkla University, Songkla, ThailandOriginal Article
