**1. Introduction**

While health services intend to address the healthcare needs of their respective populations, many a time, they are unclear as to how to expend their resources to attain optimal outcomes [1]. In times of financial constraints and increasing burden of chronic diseases, it is essential to maximise available resources to ensure sustainable healthcare delivery [2]. As funds will always be scarce in relation to growing need, appropriate choices have to be made [3]. Decision-makers need to prioritise resources for options that derive maximum benefit—public health or economic. With the growth of health service data based on technological improvements in collecting data, availability of information to make these choices has not been an issue [1]. It is rather the need for an appropriate framework, which can guide decisionmakers as to what needs to be prioritised. In this regard, evaluation, in particular, evaluation of health outcomes, as a framework has been shown to be useful to guide appropriate health service planning and implementation [1, 4, 5].
