In Ontario there are various potential sources that can contain patients' medication information. These
sources of information can be used to help inform and complete a BPMH for a patient.
To best utilize the information these sources have to offer there should be a clear understanding of the
benefits and limitations of each of these sources and how best to apply the information when
completing a BPMH. Many of the sources of information might not be a complete list of all medications
the patient is on (e.g., may only contain prescribed and not over-the-counter medications) and may only
be as up to date as the last interaction with the patient.
Unfortunately a common missing element of most sources of medication information is the inability to
record actual medication use of the patient; most sources capture prescribed use only.
These sources should be used as a starting point or a prompting tool to help frame the BPMH interview,
but should not be used as the single source of truth. Verification about how a patient actually takes each
medication should occur.
