To test the effect of district medical resource on the utilization patterns of cervical cancer screening in Taiwan. The database was retrieved from the 2005-2007 National Health Insurance (NHI). A total of 113,014 women aged 30-65 were recruited. Hierarchical linear model was constructed using district medical resource as macro level independent variable and utilization patterns of pap smear as dependent variable. The different rates of cervical cancer screening among districts are correlated with the frequency of outpatient visiting, but not the medical resources. The cause of low utilization of cervical cancer screening is not medical resource deficiency. The encouragement in outpatient would improve the utilization of pap smears for women.
