Hi there!
a lot of car t is done outpatient, at least in my experience in Massachusetts. If you think of the volume of patients receiving treatment and the limited number of inpatient beds, there's no way to accommodate everyone inpatient at the same time.
remember, the median CRS onset for cilta-cel is around 7 days. At my facility, the majority of cilta-cel patients get outpatient treatment, follow up with us daily through count recovery, and are told to notify us of any crs. If it's early onset or at least Grade 2, we get them if for toci, dex, anakinra, etc. we have an infusion room that is held in prep for this.
