RESUMO
OBJECTIVES: In this report, the authors compare immunization assessment using 2 definitions of a patient. METHODS: Two Clinical Assessment Software Application (CASA) assessments were performed. The first sampled 200 two-year-olds seen at least once since birth. The second sampled 200 two-year-olds seen in the previous year. Children with incomplete immunizations in the first sample were contacted. RESULTS: In the second sample, 72% of children had complete immunizations, compared with 46% in the first sample. In the first sample, 78% of children with incomplete immunizations had not been seen during the past year. Of 134 children in the first sample seen in the past year or successfully contacted, 75% had complete immunizations. CONCLUSIONS: The CASA assessment's definition of a patient underestimates immunization rates.
