P19S07: Attention-deficit hyperactivity
disorder (ADHD) : Drug dosage
Bottom line: Information on Attention-deficit Hyperactivity Disorder
(ADHD) was used to maintain the
management of a patient (confirm dosage of drug before re-prescription). There were no information-related patient health outcomes.
Level 1 outcome (situational relevance): On November 28, 2008, P19 did a search at work, by themselves, and
after an encounter with a patient. They retrieved two information hits about dose of Dexedrine XR. The reported search objective was: to address a clinical question. “So this gentleman [an 18 years
old male with ADHD] was being seen by the social worker because […] he had no drug
insurance to cover the cost of medication, and he’s essentially homeless. We
were looking for a way to pay for his medication and eventually we realized
that his mother’s insurance paid for his meds. [The patient] had lost the prescription that the physician
had given him for Dexedrine. I just had to reprint the prescription for her [the
physician’s] signature. I just had to double-check that
the dose was in the right range and that I had the right product before I
printed the prescription.” According to P19, e-Therapeutics+ was the only source
for information, and the found information was relevant.
Level 2 outcome (cognitive impact): The two hits were associated with a report of positive cognitive
impact (see table). Regarding learning and practice improvement, P19 stated: “It was new information. […] I didn’t know
the dose range actually, because there is a range, it’s not a specific dose.
And […] I didn’t know what strength the spansules
[sustained release capsule] came in either. […] I think that in the future at least I’ll
have an idea of what dosage range of Dexedrine XR is.”

Level 3 outcome
(information use): Information on dose of Dexedrine XR was retrieved, and used to better understand a specific issue with respect to the management of
the patient, and to maintain (be more certain about) the management of
the patient (information used as presented in e-Therapeutics+). “So the prescription was for 30 capsules, he [the patient] took one and
then his dog ate the other 29. […] My concern was did the dog really eat them
or did he sell them? The social worker and the physician are pretty confident
that the dog actually did [eat the capsules], that’s
totally consistent with this kid apparently. So he’s coming [the patient] back and
they’re going to start over. […][The management was maintained], I didn’t really
modify anything.”
Level 4 outcome (patient health): Without these information hits, P19’s management of the patient would
have been the same. There was no clear relationship between the information use
and patient health outcomes.
