Wine or Vinegar? l Overall levels of unknowns for most areas are acceptable, but – – l 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.
Improving the Vintage are l Look at individual facilities to see if there any major outliers and work with those facilities to improve the unknown rates. l 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? l – Do facilities and parents understand the importance of the data? Is there a problem with the software if using an electronic birth certificate system?
