Once this assessment has been carried out the flow
chart then guides the clinician to question whether any
intervention carried out has been successful or in other
words to ask 'Is the catheter draining now?" If the answer
to this question is 'no' then the nurse is prompted to
carry out a catheter change. The old catheter is then
exainined and if it shows positive signs ot encrustation
the nurse is directed to the long-term management plan
on rhc chart.
