There are little to no benefits to supplementary field identification programs

True, supplementary field identification programs tend to limit the use of routine programs that target service delivery using routine systems.

Explanation:

When supplementary field identification programs are applied in a study, they have damaging effects to other systems and programs already in progress targeting certain/similar variables in a study group. Such programs are initiated to boost the already existing systems of programs that are in continuous application (routine basis). As a supplement, we expect more positive results in the rates per the variables included in a study. However, results has proved the opposite. For example, supplementary immunization activities applied in programs targeting demographic and health systems services reveled that such programs reduce the probability of receiving the services provided by other routine health systems conducting continuous vaccination programs to the target groups.
