Dialysis in treatments and intakeOutput tables

[FrancescaAlf]

Hi, I am looking both into treatment and intakeOutput tables with the aim of extracting dialysis info. In the treatment table: 8298 stays have data about dyalitic therapy. In the intakeOutput table: 5030 stays have a value != 0 in the column "dyalisistotal". The number of common stays between tables is only 2511. What is the reason? Which table contains more accurate data about dialysis?

I noticed that (in intakeOutput) there are data about dialysis after the ICU discharge, are those data accurate? Also, where do I find the end time of dyalitic therapy?

Thanks
