New York City Background • Population: 8. 2 million • Annual birth cohort of ~124, 000 • 65% of children VFC-eligible • High mobility of the population within the city • Child immunizing sites ~1, 500 • Number of pediatric practitioners estimated to be >5, 000 • 77. 2% vaccine coverage rate for 4: 3: 1: 3: 3: 1 (National Immunization Survey, 2004)
Citywide Immunization Registry (CIR): Background • Mandatory reporting of immunizations administered to children • Birth to < 8 years old since January 1, 1997 • Birth to < 19 years old since August 18, 2005 • 2. 5 million records and over 21. 4 million immunization events • Birth certificates loaded weekly
CIR Status • Reporting Compliance: • 100% of public sites report (81/81) in last 6 months • 74% of private sites report (904/1226) in last 6 months • Registry Completeness: • 72% of children age 6 mo - 6 yrs have 2 or more immunizations in CIR • Average of 14. 7 immunizations per 2 year old child • Captures ~ 75% of immunizations given
NYC Vaccines for Children Program (VFC) • 1, 301 Sites • 81 public • 1220 private • 2. 5 million vaccine doses distributed in 2005 • 12, 000 orders in 2005 ~ 48 orders / workday • 361 (28%) sites visited in 2005 • Vaccines given only for VFC-eligible children (non -universal project)
Objectives • Increase accountability of VFC purchased vaccines • Reduce paperwork for provider and VFC staff • Increase CIR completeness • Develop provider profile to improve interactions with providers
Doses Administered Report (DAR) • Currently required to order VFC vaccine • Self-reported by provider of aggregate doses Problems • Time consuming for provider to complete • Time consuming for VFC staff to manually enter data into VACMAN database • Data non-verifiable – aggregate reports do not permit program audit • Duplicative process – providers report similar information to Health Dept. via CIR
Expansion of CIR: An Opportunity • Barrier to using CIR to produce DARs was that providers were only required to report vaccines given to children < 8 years • August 2005: NYC Health Code mandate for reporting to CIR was amended to include all individuals < 19 years • Urged providers to include VFC-eligibility status when reporting to CIR • Added VFC eligibility status field to online registry
Method: Notify Providers • Letter sent to all providers on 01/17/06 announcing transition to accepting only CIR-generated DARs starting 09/01/06 • VFC vaccine shipments will be based on number of doses reported to CIR • Letter distributed in numerous ways: • • • Certified mail to all VFC providers Mailed to all CIR Facilities E-mailed to all CIR contacts Included in all VFC shipments Broadcasted citywide through the Health Alert Network
Method: Linking Vacman & CIR database • VFC pin & CIR Facility Code • Each VFC pin must be matched to one CIR Facility Code • Correct matching essential to comparing: • # of VFC vaccine doses shipped • # of doses reported to CIR
Match Database – Main Page Start with VFC pin #
Match Database – CIR Facilities Identify possible CIR Facility Code match
Match Database – Main Page Call Provider
CIR Generated DAR: Network
CIR Generated DAR: Group
CIR Generated DAR: Facility
Results As of 02/10/06 • Linking: • 65% of VFC pins matched to CIR codes (850/1301) • Reporting for VFC pins linked to CIR facility codes: • 71% of VFC doses were reported to CIR • 27% of sites report > 90% of VFC doses to CIR • 13% of sites report > 75 to < 90% • 18% of sites report > 50 to < 75% • 42% of sites report < 50%
Anticipated Benefits • Providers: • Reduce record keeping and paperwork • Eliminate duplicate reporting • Identify problems in electronic record keeping • VFC: • Improve validity of Doses Administered Report • Reduce time spent entering data • Reduce time spent managing incoming faxes • CIR: • Recruit providers who receive VFC vaccine but do not report to CIR • Collect more complete immunization data • Update existing provider demographics
Conclusion • Linking Registry and VFC databases • is feasible • will provide Bureau the ability to target providers that need assistance more efficiently • demonstrates program responsiveness to provider requests to eliminate duplicative reporting
