Immunization status of children enrolled in a hospital-based Medicaid managed care practice : the importance of the timing of vaccine administration.
To evaluate the immunization status of children enrolled in a hospital-based Medicaid managed care practice and to assess the impact of the timing of vaccine administration on measured immunization rates.
Design and methods
The medical records of all children between the ages of 19 and 35 months who were continuously enrolled in the Medicaid managed care practice for the last 6 months of 1996 were reviewed.
Immunization status was determined for the following vaccines :
diphtheria-tetanus-pertussis/diphtheria-tetanus-acellular pertussis (4 doses) ;
Haemophilus influenzae type b (3 doses) ;
poliovirus (3 doses) ;
hepatitis B (3 doses) ;
measles-mumps-rubella (1 dose) ;
and overall for the basic series.
Two assessment methods were used to determine the immunization status of the study children : (1) a count of all documented vaccines ( « count ») ; and (2) only including vaccines that met minimal age and spacing intervals based on American Academy of Pediatrics and CDC recommendations ( « interval assessment »). Results.
With the count method vaccine-specific immunization rates ranged from 88 to 95%, with overall coverage of 80% for the basic series.
With the interval assessment method vaccine-specific immunization rates ranged from 74 to 92%, with overall coverage of 53% for the basic series. (...)
