  12. Timeliness and New Items

  13. Average Lag in Days Between Reporting Period and Receipt of Data at NCHS by Year Revised (150-301)* (25-176)* (10-192)* (12-38)* (5-51)* NOTE: *range of days

  14. THE PENNSYLVANIA DATA VINEYARD

  15. *targeted= 5 facilities with highest unknown rates

  16. A B E C D PA PA W/O PA W/O is state rate without 5 targeted facilities

  17. *targeted= 5 facilities with highest unknown rates

  18. Wine or Vinegar? • Overall levels of unknowns for most areas are acceptable, but • They can vary widely by state AND, more importantly… • Unknowns generally decline for all areas following the first year of implementation • Timeliness also tends to improve quite dramatically following the first year of revision • Timeliness was much improved for states which revised in 2006-2007 compared with those that revised 2003-2005.

  19. Improving the Vintage • Look at individual facilities to see if there are any major outliers and work with those facilities to improve the unknown rates. • Does it appear all facilities are having high unknowns in certain items? If so, • Can the birth clerk/registrar find the information in the records? • Is there a problem with the wording of the item? • Do you need to do more education on the item? • Do facilities and parents understand the importance of the data? • Is there a problem with the software if using an electronic birth certificate system?
