Compliance or non-compliance with treatment?.

In a situation in which a patient, currently undergoing medical treatment at 
home requiring compliance and fairly rigid discipline for its effectiveness, is 
found by the health visitor not to be carrying out the 
prescribed treatment, should the health visitor's role always be to attempt 
to influence the patient to comply with the required treatment or 
are there occasions when it might be acceptable for her to 
disregard this positive role? To illustrate such a situation, the real-life 
experience of two families will be discussed.
