13 First Guideline of CPD diagnosis
(modified from ACOG recommendation) 1. Cervix ≥ 3 cm. 2. Good uterine contraction ≥ 2 hrs. 3. Protraction or arrest disorder 4. If 1, 2, 3 are not met, needed two obstetricians evaluation. CPG was approved by Department committee and implemented in 2000

14 Cesarean section rate due to CPD was
Physician compliance with the CPG was 89.2% Cesarean section rate due to CPD was decreased from 10.7% in 1999 to 8.6% in 2002 Pregnant outcomes were not different between the two periods C.Suwanrath-Kengpol et al. Int. J. for Quality in Health Care 2004;16;

but higher than WHO recommendation Department committee approved revised CPG in December 2002 Revised CPG was implemented in January 2003

25 Outcomes of Revised CPG
Compliance with the revised CPG = 83% (target compliance = 85%) After revised CPG, no adverse effect of pregnancy outcomes Cesarean section rate did not decrease within 1 year period

26 Summary Using the revised CPG: decreased the difference of cesarean section rate between private and non-private groups (7% vs. 4%) CPG Evaluation as research (2 publications) Using CPG as a study model for medical personnel
