It is recommended that an ISC be performed at least every 4-6 hours with a new catheter each time. However, this is individual and depends on a number of factors. So can be anywhere from 1-8+ per day, average number would be 4-6 per day.
Why does my patient need me to prescribe more than one kind of catheter?
If a patient is on ISC it is beneficial to have access to an IDUC for infection/long distance travel etc, they also may require different types of ISC (bag attached or non attached) depending on access when at work/friends /social etc
