This is a cross sectional study to assess the performance of Putrajaya Health Clinic in meeting the client's expectation among 403 clients who came to seek medical treatment through a systematic random sampling in the month of July 2006. Our aim is not only to reduce dissatisfaction among clients but also try to meet their expectations; we have adopted SERVQUAL method which defined satisfaction as the difference between perceptions and expectations. We would also like to refer this dissatisfaction as not able to meet clients' expectations. It was found that there were only 6.9% of clients dissatisfied in Putrajaya Health Clinic, but they had not been able to meet 81.5% of clients' expectation. As for demographic characteristics, there appeared to be a significant association between client's satisfaction and age, gender, ethnicity and educational level. For outpatient's, the greatest dissatisfaction is in the dimension of Reliability. Clients were not happy with the waiting time at the clinic. Apart from recruiting more staff, management should develop a comfortable waiting environment to reduce the agony of waiting.
