In many healthcare scenarios, there is a lack of precise definition about the outcomes since quantifiable outcome parameters are difficult to discern. Despite this, evaluation of quality of healthcare still remains an issue of paramount importance for all service providers since consumers or patients inclination to any service is dictated by the quality of the available services (Fitzpatrick 1993). Since patients are important components of this system, one of the important variables that determine outcomes of any care remains to be patient satisfaction. Many studies now incorporate patient satisfaction to be a major identifier and an essential component of care quality. Doll (1973) proposed that even for an organisation like NHS (National Health Service) the evaluation of service parameters should have at least three distinct criteria, namely, clinical outcomes, cost-effectiveness, and social acceptability with the later indicating satisfaction of the patients (Doll 1973).
As far as quality is concerned, quality is a class of functionally related attributes of heterogeneous assortment, this context research in this area tends to derive and examine data from a variety of resources. Although the data from other sources such as administrative records or treatment charts are easy to use, these do not reflect the true parameters of client satisfaction as a measure of quality of care. Recent studies focus on direct observations of patient-provider interactions, questionnaires related to outcomes, and above all, patient surveys. Information directly available from consumers, usually in the form of patient satisfaction surveys may
