Dear All
I'd be grateful for any opinions concerning the definition of an 'occasion' for the
purposes of estimating interoccasion variability. In our study, critically ill
paediatric patients will receive a continuous variable rate i.v. infusion over
several days. Blood samples (at least two) will be collected each day. Is it
reasonable to treat each consecutive day as a different occasion?
Many thanks
Ann
