Actually research shows that many central line catheter infections are preventable. The AHRQ and CDC have published best practices and checklists, yet many hospitals still don't adhere to those.
> many central line catheter infections are preventable
Again, of course some of them are preventable, and nobody's saying its OK to install central lines without putting gloves on, and so on. However, there is a baseline rate of infection which is not preventable, and will continue to happen. Check the Figures S1 and S3 in this recent study : http://www.nejm.org/doi/suppl/10.1056/NEJMoa1500964/suppl_fi...

What is the source ? As far as I'm aware, around ~ 90% facilities do have checklists -- I do not follow this literature closely, though.
