What is the evidence of general effect of extra hours of contact being associated with improved outcomes in high risk patients?
There seemed to be evidence of a general effect of extra hours of contact being associated with improved outcomes in high risk patients, with some caveats. First, there seems to be a ceiling effect: although some shorter interventions delivered improvement, extended follow-up (over years) in a clinic offered little benefit; and delivering 40 hours of contact gave only the same benefit of 20 hours of contact.
