TI  - Further observations on comparison of immunization coverage by lot quality 
      assurance sampling and 30 cluster sampling.
PG  - 267-73
AB  - 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 of TT. TT coverage in 149 
      contemporary mothers sampled in EPI survey was also 42% (95% CI 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 method to monitor 
      health programs on a routine basis in small population sub-units, especially in 
      areas with high and heterogeneously distributed immunization coverage.
