  1. Further observations on comparison of immunization coverage by lot quality assurance sampling and 30 cluster sampling.

    Article - En anglais

    Lot Quality Assurance Sampling (LQAS) and standard EPI methodology (30 cluster sampling) were used to evaluate immunization coverage in a Primary Health Center (PHC) where coverage levels were reported to be more than 85%. Of 27 sub-centers (lots) evaluated by LQAS, only 2 were accepted for child coverage, whereas none was accepted for tetanus toxoid (TT) coverage in mothers.

    LQAS data were combined to obtain an estimate of coverage in the entire population ; 41% (95% CI 36-46) infants were immunized appropriately for their ages, while 42% (95% CI 37-47) of their mothers had received a second/booster dose ofTT.

    TT coverage in 149 contemporary mothers sampled in EPI survey was also 42% (95% Cl 31-52).

    Although results by the two sampling methods were consistent with each other, a big gap was evident between reported coverage (in children as well as mothers) and survey results.

    LQAS was found to be operationally feasible, but it cost 40% more and required 2.5 times more time than the EPI survey.

    LQAS therefore, is not a good substitute for current EPI methodology to evaluate immunization coverage in a large administrative area.

    However, LQAS has potential as a method to monitor health programs on a routine basis in small population sub-units, especially in areas with high and heterogeneously distributed immunization coverage.
