Overview
This template is a chart audit for children who turn age 2 during the measurement period and need review against the Combination 10 immunization set used for UDS childhood immunization status reporting. It gives reviewers a structured way to confirm eligibility, verify each vaccine component, check that all qualifying doses were given on or before the second birthday, and record whether the chart supports the result.
Use it when you need a repeatable audit trail for pediatric quality reporting, especially when records may come from the EHR, an immunization registry, scanned outside records, or a mix of sources. The template helps you separate a true measure pass from a chart that merely looks complete at first glance. It is also useful when you need to identify missing doses, late doses, or documentation gaps that prevent a valid finding.
Do not use it as a vaccination schedule tool or as a substitute for clinical decision-making. It is not meant to determine whether a child should receive catch-up immunizations, nor does it replace local registry reconciliation workflows. If the chart lacks clear dates, the source cannot be verified, or a dose was administered after the second birthday, the audit should record the deficiency and route it for follow-up. The result is a cleaner, defensible quality review that supports accurate reporting and targeted corrective action.
Standards & compliance context
- This template supports UDS childhood immunization reporting by standardizing review of vaccine completion and documentation for age-2 patients.
- It aligns with quality management practices used in healthcare programs that rely on auditable source documentation and repeatable chart review.
- If your organization uses state immunization registries, the template can help verify that registry data and chart documentation are consistent before reporting.
- The audit should follow your local pediatric quality policy and any applicable public health reporting requirements for immunization records.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template
Audit Scope and Patient Eligibility
This section matters because it defines which children belong in the audit and prevents invalid chart selection from skewing the result.
-
Patient turns age 2 within the measurement period
Verify the child is included in the audit population based on turning 2 years old during the applicable measurement period.
-
Date of second birthday documented
Record the child’s second birthday used as the cutoff date for vaccine completion.
-
Chart contains sufficient documentation for immunization review
Confirm the chart includes enough evidence to determine immunization status, such as immunization history, registry data, or provider documentation.
-
Audit source identified
Identify the primary source used to validate immunization status.
Combination 10 Vaccine Completion
This section matters because it checks each required vaccine component individually instead of assuming the series is complete from a summary view.
-
DTaP series documented per measure requirements
Verify DTaP doses are documented and meet the measure’s completion criteria by age 2.
-
IPV series documented per measure requirements
Verify IPV doses are documented and meet the measure’s completion criteria by age 2.
-
MMR series documented per measure requirements
Verify MMR doses are documented and meet the measure’s completion criteria by age 2.
-
HiB series documented per measure requirements
Verify Haemophilus influenzae type b immunization documentation meets the measure’s completion criteria by age 2.
-
Hepatitis B series documented per measure requirements
Verify hepatitis B doses are documented and meet the measure’s completion criteria by age 2.
-
Varicella (VZV) series documented per measure requirements
Verify varicella vaccination documentation meets the measure’s completion criteria by age 2.
-
Pneumococcal series documented per measure requirements
Verify pneumococcal vaccination documentation meets the measure’s completion criteria by age 2.
-
Hepatitis A series documented per measure requirements
Verify hepatitis A vaccination documentation meets the measure’s completion criteria by age 2.
Timing and Documentation Validation
This section matters because the measure depends on both the date of administration and the quality of the supporting evidence.
-
All qualifying vaccine doses were administered on or before the second birthday
Verify the administration dates for all required vaccine components fall on or before the child’s second birthday.
-
Immunization dates are clearly documented in the chart
Confirm dates are legible and traceable to a source record, registry, or encounter note.
-
Evidence source supports each vaccine component
Verify each required vaccine component can be traced to a documented source in the chart or immunization registry.
-
Any missing or delayed doses identified
Select any vaccine components that are missing, incomplete, or not documented by the second birthday.
Findings and Corrective Action
This section matters because it turns the review into an actionable quality record with a clear result, deficiency summary, and next step.
-
Audit result
Indicate whether the chart meets the childhood immunization status measure.
-
Deficiency summary
Summarize any non-conformance, missing documentation, or vaccine gaps identified during the chart audit.
-
Corrective action needed
Select any follow-up actions required to resolve documentation gaps or vaccine deficiencies.
-
Reviewer notes
Add any additional notes relevant to the audit, including exceptions, registry discrepancies, or chart limitations.
How to use this template
- 1. Confirm the child turns age 2 within the measurement period and record the exact second-birthday date used for the audit.
- 2. Open the chart and identify the source you will use for immunization evidence, such as the EHR record, registry entry, or verified external documentation.
- 3. Review each Combination 10 component one by one and mark whether the documented series meets the measure requirements before the second birthday.
- 4. Compare every qualifying dose date against the second-birthday cutoff and flag any missing, delayed, or unclear entries as deficiencies.
- 5. Record the audit result, summarize the gap if the chart fails, and assign corrective action such as chart correction, registry reconciliation, or staff follow-up.
Best practices
- Review the chart in the same order every time so eligibility, vaccine completion, timing, and findings are captured consistently.
- Use the actual administration date for each dose, not the date the record was entered into the chart.
- Treat missing source documentation as a finding even if the vaccine is mentioned in a note without a verifiable date.
- Flag any dose given after the second birthday as non-qualifying for this measure, even if the series is otherwise complete.
- Check that the evidence source is specific enough to support each vaccine component rather than relying on a general immunization summary alone.
- Document whether the issue is a true clinical gap or a documentation gap so the follow-up action matches the problem.
- If the chart and registry disagree, note the discrepancy and route it for reconciliation instead of guessing which record is correct.

Common use cases
Frequently asked questions
What does this audit template verify?
It verifies whether a child who turned age 2 during the measurement period has documentation showing the Combination 10 immunization set was completed on or before the second birthday. The template also checks that the chart contains enough evidence to support each vaccine component and that dates are clearly recorded. It is designed for chart review, not for administering vaccines or managing the clinical schedule.
Who should use this template?
Quality staff, clinical auditors, population health teams, and medical assistants assigned to UDS reporting support can use it to review pediatric charts. A reviewer should understand immunization records, source documents, and how to interpret missing or partial vaccine histories. It is especially useful when one person collects chart evidence and another validates the final finding.
How often should this audit be run?
Run it on the cadence required for your reporting cycle, then again before submission to catch late documentation or data-entry errors. Many teams use it as a periodic internal audit during the measurement period and as a final pre-reporting validation. If your registry or EHR imports are delayed, add an extra review pass.
What counts as acceptable documentation for the audit?
Acceptable documentation is whatever your organization uses as a reliable source for immunization status, such as the EHR immunization record, a verified state registry entry, or scanned external records that can be traced to the child. The key is that each vaccine component in the Combination 10 set must be supported by clear dates and evidence. If the source is ambiguous, the chart should be marked as a deficiency until resolved.
Does this template replace clinical judgment or registry reconciliation?
No. It is a quality audit tool for confirming measure compliance from existing documentation, not a substitute for clinical review or registry reconciliation. If the chart and registry disagree, the reviewer should note the discrepancy and route it for correction according to local workflow. The template helps standardize the finding, but it does not decide whether a vaccine should be given.
What are the most common pitfalls when using this audit?
Common pitfalls include counting doses given after the second birthday, accepting incomplete series documentation, and overlooking missing source evidence for one of the vaccine components. Another frequent issue is assuming a vaccine is valid because it appears in the chart without checking the actual administration date. This template forces the reviewer to separate presence of a record from measure-eligible completion.
Can this template be customized for local reporting rules?
Yes. You can add fields for your state registry, EHR source, reviewer role, or local pediatric quality program while keeping the core Combination 10 and timing checks intact. If your organization tracks additional documentation rules, add them to the findings or reviewer notes sections. Keep the audit criteria aligned to the reporting specification you are using.
How does this compare with an ad hoc chart review?
An ad hoc review often misses one of the vaccine components, forgets to confirm the second-birthday cutoff, or leaves findings too vague to act on. This template standardizes the walk-through so every chart is reviewed the same way and every deficiency is recorded in a usable format. That makes it easier to trend errors, coach staff, and defend the result during reporting review.
