Stage of development
Potential or current usage
This measure has been part of the PHO Performance Programme's National Indicator Set since 1 January 2006 and is used to measure how many children in the 2 year old cohort are fully immunised by age 2 years.
Brief Overview of the Measures
This measure focuses on how many children in the 2 year old cohort are fully immunised by age 2 years.
Rationale for selection
Children who receive the complete set of age appropriate vaccinations (in this case for the 2 year old age group) are less likely to become ill from certain diseases. The vaccinations which fall within the 2 year old group are for measles, mumps, rubella, diphtheria, tetanus, whooping cough, polio, hepatitis b, pneumococcus and haemophilus. A child must receive the complete set of 2 year old vaccinations to be counted by the Programme.

Application and interpretation of the measure
Stated intent of the measure
Ensuring children in the 2 year old cohort are fully vaccinated by age 2 years.
Level of health care delivery/setting
This measure is currently reported by the PHO Performance Programme to PHO level although use of this measure to monitor practice and patient level performance is also possible.
All children who are 1 year and 364 days old All children who are 1 year and 364 days old and are within the high need population (identified as Māori or Pacific Island)
Stratification by vulnerable populations
The PHO Performance Programme currently uses this measure to monitor at both a total PHO enrolled population level (all PHO enrolled eligible patients) and a high need PHO enrolled population level (whereby high need is identified as Māori or Pacific Island)
This measure is currently funded through the PHO Performance Programme both at a total population level and a high need level.
Calculation of the measure
Output of calculation
Percentage of enrolled children in the 2 year old cohort who are fully vaccinated by age 2 years.
Number of enrolled children within the reporting period whose second birthday fell during the reporting period who had received their final dose (fully immunised) vaccination on or before their second birthday for the full set of vaccines included in the national immunisation schedule and health target.
Number of enrolled children within the reporting period whose second birthday fell within the reporting period.
Criteria/standard for optimal performance
Every practice within a PHO should have a process in place for identifying / recalling children for their age appropriate vaccinations. The PHO Performance Programme goal is: 90% or more of a a PHO’s 2 year old cohort are fully vaccinated by age 2 years.

Appraisal of the measure
Initial selection of this indicator in 2005 was done by the Ministry of Healh using a consensus process. Since then the indicator has been reviewed and refined in consultation with the PHO.
