I had asked that of somebody and their response was that vital records would be different than medical records, because vital records are legal proof that a hospital might need - for instance if some parents claimed that the hospital had mixed up which infant they sent home with them.
If you’re still at a hospital maybe you could ask if they treat vital records differently than the medical records. Do they keep a birth certificate in the medical chart/file, or are the BC’s stored somewhere else? Are death certificates stored in the medical files?
Vital records executed at the hospital do not remain after they are filed with the appropriate authority.
They are not subject to 25 year retention (because they are filed in a permanent repository elsewhere).
We don’t keep ‘em for a week.
