Data Quality –Birth and Death Certificate Items
  • NAPHSIS/NCHS retreat –What items should be studied? Should items be deleted? How will this be done?
  • Retreat institutes 3 working groups: 1) Timeliness; 2) IT; 3) Data Quality
  • Data Quality members included: Isabelle Horon, Cynthia Hooley, Jennifer Woodward, Stephanie Ventura, Joyce Martin, Donna Hoyert and Charlie Rothwell
workgroup process
Workgroup Process
  • NCHS presented items that could be deleted and why and items we felt should be studied
  • NAPHSIS surveyed states on 3 items NCHS suggested dropping and requested information on data quality on other items.
survey results
Survey results
  • 3 items NCHS would like to drop –results inconclusive
  • many States for a variety of reasons do not know about the quality of these 3 items or other items for births and deaths.
  • overlap between items NCHS wants studied with items of quality concern to the States.
joint recommendations
Joint Recommendations
  • Funding should be available for quality studies in states throughout the five years of the contract.
  • The primary purpose of these studies is to improve data quality not delete data items
  • These funds would be in addition to the funds negotiated with the states for the provision of vitals data to NCHS.
joint recommendations1
Joint Recommendations
  • Roundtable discussions on items to be studied – We need your input! Use the spreadsheets I sent you!
  • The results from the survey, comments received at the annual meeting and the work of an ongoing joint state/NCHS committee will determine what data items will be studied during the contract period.
joint recommendations2
Joint Recommendations
  • Any items that are deleted can still be collected by state systems and provided to NCHS … NCHS just won’t use them
  • Items deleted will not impact the contracts – i.e. contract $’s will not be reduced
  • Modification of items after QC studies will be implemented through joint NAPHSIS/NCHS agreement
nchs recommendation
NCHS Recommendation
  • Delete “Non-vertex presentation”
  • Delete “Was delivery with forceps attempted by unsuccessful”
  • Delete “Was delivery with vacuum extraction attempted by unsuccessful”
non vertex presentation characteristics of labor and delivery
Non-vertex Presentation(Characteristics of Labor and Delivery)
  • Data Quality: new checkbox item - substantially underreported.
  • Data utility: under-reporting for this makes its use in research potentially misleading . More detailed and complete information on presentation at birth is available from the Method of Delivery items “breech” and “other presentation.”
  • Potential for improvement: EHR’s?
was delivery with forceps attempted but unsuccessful
Was delivery with forceps attempted but unsuccessful?
  • Data quality: Very poor
  • numerous comments/questions from state colleagues and hospitals staff that these questions are confusing
  • The distribution of records for this item for the 2006, 19-state revised reporting area reveal fundamental inconsistencies in these data.
  • Data utility: Low
delivery with vacuum extraction
Delivery with vacuum extraction
  • Same issues as forceps
  • forceps and vacuum deliveries are becoming rarer and rarer events (only 0.8 and 3.7% of all births in 2006) and expected to decline further.
  • Potential for improvement for both: EHR’s?
come to the roundtable discussions
Come to the Roundtable Discussions!
  • What items should be studied first?
  • How should changes be made without causing chaos?
  • Do you think the 3 items that NCHS suggests dropping should be kept, dropped, modified … and why?
