Results: Of the 330 patients, 71.5% were female, 57.0% graduated a bachelor degree, 76.7% lived in Bangkok and nearby provinces, and 37.9% used civil servant medical benefit. Among 75.5% of patients had general appointments, 24.5% had intervention appointment, 72.1% experienced missed appointments, and only 27.9% never been defaulted. Factors associated with never been defaulted appointments were degree graduation higher than bachelor degree, appointment for intervention, conveniency of commuted methods, and lesser waiting time at the hospital.
