The improvement of health care service has a great effect on patient satisf
action. During the service delivery, the health care organization attempts
to answer the reasonable expectations of patients. The expectations relate
to many service dimensions, among them the phone system, appointment availa
bility, and waiting times. The research questions of this study are: can th
e implementation of quality initiatives improve patient satisfaction with t
he phone system, appointment availability, and waiting times and do patient
s from diverse cultural backgrounds exhibit different levels of satisfactio
n? The study was undertaken in a public clinic, with a culturally diverse c
lientele, including 194 patients. The authors use a combination of the long
itudinal and cross-sectional research design to test the propositional mode
l. The findings show that the implementation of the quality initiative sign
ificantly improved patient satisfaction with the appointment availability a
nd waiting time. On the other hand, the implementation of the quality initi
ative did not improve patient satisfaction with the phone system. Some cult
urally diverse patients exhibited different levels of expectations of the c
are provider and quality in terms of patient satisfaction with the appointm
ent availability.
