Considering ethics in community eye health planning: perspectives from an existing model

Despite the widespread acceptance of the principles of the Alma Ata Declaration of 1978 and the subsequent amendments, health for all has remained a distant dream in many parts of the developing world. Concerns such as the economic efficiency of health systems and their reach and coverage have dominated discussions of public health, with ethics remaining at best a shadowy set of assumptions or at worst completely ignored. Similarly, questions of ethics have been taken for granted and rarely addressed directly in the design of public health models across sectors and are rarely explicitly addressed. This paper uses the experience of the L V Prasad Eye Institute's (LVPEI) pyramidal model of eye healthcare delivery to explore ethical issues in the design and implementation of public health interventions. The LVPEI model evolved over time from its beginnings as a tertiary care centre to a network that spans all levels of eye care service delivery from the community through primary and secondary levels. A previously published analytical framework is applied to this model and the utility of this framework as well as the ethics of the LVPEI model are interrogated. An analytical and prescriptive framework is then evolved that could be used to build in and evaluate ethics in other public health delivery models.
