- The D2D 3.0 definition fully aligns with Public Health criteria. This means Rotavirus is now included in the definition and EMR queries. It is not part of the preventive care bonus; therefore, performance may appear lower than in your preventive care bonus reports which exclude Rotavirus.
- The D2D definition does not reflect patient choice. Patients who decline immunization and therefore are not immunized may be the reason why your rates are lower than you expect. See “data quality actions” for ideas to examine the extent to which this is affecting your rates.
- Data for patients immunized outside of the primary care team (e.g. at a health unit) might not be recorded consistently in all EMRs and teams. The performance seen in D2D 3.0 might therefore under-estimate actual immunization rates. See “data quality actions” for ideas to examine the extent to which this is affecting your rates.
- Rates for teams with very few children in their panel may be more variable than rates based on larger eligible patient populations. For example, if 2 less children are immunized this year out of a population of 10 children, your immunization rate will drop by 20%. However, if 2 less children out of 100 are not immunized, your rate will only drop by 2%. So consider how many children are eligible for immunization when interpreting differences for your team year to year or relative to another team.
- D2D 3.0 includes data for all children as opposed to only rostered children. This might generate different rates than those the team might be used to seeing in reports based on rostered children only (e.g. the MOHLTC Preventive Care Target Population/Service Report (TPSR)). The MOHLTC provides eligible physicians in Patient Enrolment Models (PEMs) with a Projected Preventive Care Target Population/Service Report semi-annually, in April and September, to assist them in determining their Target Population and the delivery of preventive care services.
- The timing of D2D reporting may not coincide with the reporting time period for the MOHLTC Preventive Care Target Population/Service Report. There may be differences in rates related to these differences in time periods.
- Although a consistent definition was developed to create queries that were shared among members for purposes of extracting these data for D2D 3.0, it is possible that the extent to which these data were consistently recorded and therefore extracted in your team might vary. To explore this issue, look at the processes used in your team to record and extract immunization data and work to align it as much as possible with the standard process being developed by QIDS Specialists.
