P12S08: Atacand and Potassium
chloride
Bottom line: Information on Atacand and Potassium
chloride was used to maintain the management plan (stop potassium supplement),
and to persuade other
health professionals to make this change. There were no information-related patient health outcomes.
Level 1 outcome (situational relevance): On October 24, 2008, P12 did a search at work, by themselves, and
after an encounter with a patient. They retrieved one information hit about Atacand and Potassium chloride. The reported search objective was: to address a clinical question. I was sending a note to the doctor to suggest
that she [the patient, a woman in her seventies] should think about stopping the potassium
supplement because the Atacand [...] and the Spironolactone can both increase
potassium. So I was concerned about her [the patient] taking a potassium supplement in addition to [Atacand and the
Spironolactone]. [...] I went and created this pharmaceutical
opinion with the substantiated evidence to send to her [the patients] family doctor. [...] It [the search around this clinical question] was for a
specific patient that was taking all three of these medications. According to P12,
e-Therapeutics+ was the only source for information, and the found information
was relevant.
Level 2 outcome (cognitive impact): One hit was associated with a report of positive cognitive impact (see table). Regarding confirmation,
reassurance, and reminder, P12 stated: I already knew that the interaction was
there, I just wanted the substantiating evidence to be able to send it to the
doctor. [...] I thought I knew the answer and so it
confirmed what I thought.

Level 3 outcome
(information use): Information on Atacand and Potassium chloride was retrieved, and used to maintain (be more
certain about) the management plan (stop potassium supplement), and to persuade other
health professionals to make this change (information used as presented in
e-Therapeutics+). [The information
was used] to persuade the physician to agree to stop
it [to stop the potassium supplement].
Level 4 outcome (patient health): Without this information hit, P12s management of the patient would have been
the same. There was no clear relationship between the information use and
patient health outcomes.
