“…Results from different audits and evaluations published in the literature have demonstrated vastly different results, reinforcing the need to validate data from registers before use. Many audits, such as those from the national immunization registers in the United Kingdom, ( 11 ) Belgium, ( 7 ) Australia ( 8 ) and some subnational immunization registers in the United States of America (USA), ( 12 , 13 ) have demonstrated a high degree of completeness and accuracy with coverage estimates within 10% of coverage estimated from vaccination surveys. ( 7 , 8 ) However, other audits have demonstrated variability in completeness and accuracy with some noting an improvement in completeness over time from 71.4% to 97.7%; ( 14 ) others noted an improvement in accuracy from an error rate of 59% to 18% following specific strategies.…”

IntroductionMonitoring of vaccination coverage is vital for the prevention and control of vaccine-preventable diseases. Electronic immunization registers have been increasingly adopted to assist with the monitoring of vaccine coverage; however, there is limited literature about the use of electronic registers in low- and middle-income countries such as Mongolia. We aimed to determine the accuracy and completeness of the newly introduced electronic immunization register for calculating vaccination coverage and determining vaccine effectiveness within two districts in Mongolia in comparison to written health provider records.MethodsWe conducted a cross-sectional record review among children 2–23 months of age vaccinated at immunization clinics within the two districts. We linked data from written records with the electronic immunization register using the national identification number to determine the completeness and accuracy of the electronic register.ResultsBoth completeness (90.9%; 95% CI: 88.4–93.4) and accuracy (93.3%; 95% CI: 84.1–97.4) of the electronic immunization register were high when compared to written records. The increase in completeness over time indicated a delay in data entry.ConclusionThrough this audit, we have demonstrated concordance between a newly introduced electronic register and health provider records in a middle-income country setting. Based on this experience, we recommend that electronic registers be accompanied by routine quality assurance procedures for the monitoring of vaccination programmes in such settings.

“…Immunizations provided by both public and private providers in Wisconsin are uploaded into the registry, and 98.5% of Wisconsin adults having an active WIR [ 30 ]. Studies have demonstrated that the WIR captures 97% of vaccines administered in Wisconsin [ 31 ]. The WIR is directly incorporated into the University of Wisconsin Hospital and Clinics EMR.…”

Accuracy of Self-Reported Vaccination Status in a Cohort of Patients with Inflammatory Bowel Disease

Background and Aims Prevention of vaccine-preventable diseases is important in the care of patients with inflammatory bowel disease (IBD). Thus, accurate immunization histories are critical. Many providers rely on patient self-report when assessing immunization status. The primary aim of our study was to determine the accuracy of self-reported influenza vaccination status in a cohort of patients with IBD. Methods We conducted a prospective study of patients with IBD who answered a vaccination status questionnaire and compared their responses to the Wisconsin Immunization Registry, a statewide electronic immunization information system. The primary outcome was the sensitivity and specificity of self-reported influenza vaccination status. A secondary outcome evaluated the sensitivity and specificity of pneumococcal vaccination status. Results A total of 200 patients with IBD were included in the study. Documented immunization rates were 74.5% for influenza vaccinations and 79.9% for pneumococcal vaccinations. Influenza vaccination self-report had a sensitivity of 98.7%, a specificity of 90.2%, a positive predictive value (PPV) of 96.7% and a negative predictive value (NPV) of 95.8%. In comparison, the sensitivity for pneumococcal vaccination was 83.5% with a specificity of 86.2%, PPV of 96.4%, and NPV of 54.3%. Conclusions Self-reported influenza immunization status is sensitive and specific in patients with IBD. Accuracy for pneumococcal vaccination is slightly lower, but responses were notable for a high PPV. Self-report is an effective way to determine influenza immunization status and provides useful information for receipt of pneumococcal vaccine in patients with IBD.

“…While staff at local Quality Improvement health departments routinely enter into the registry records of vaccinations administered before 2000, staff at primary care clinics or pharmacies do not always. 30 Furthermore, vaccines administered in different states rarely make it into the registry. As a result, compared to children, adults have less complete documentation of vaccinations in the registry.…”
