Definition: Medication reconciliation is a process that involves several clinical steps:
- Upon admission, obtain the complete list of medications the patient is taking (or should
be taking) prior to admission (e.g. the patient's "medication history"). This list should be
obtained from the patient, whenever possible, although other resources (e.g. family, caregivers,
community pharmacies, past medical records, primary care physician) may need to be contacted
as needed. This list should be documented in a single location within the medical record that is
utilized and is accessible to all healthcare providers.
- After documentation, this list is confirmed with the patient, or additional resources if needed, to
help ensure accuracy and completeness.
- Once admission orders are written, they are compared (reconciled) against this medication
history list to ensure there are no unintended differences (i.e., confirming that any changes,
omissions or additions are purposeful based on the patient's current clinical status and/or our
formulary.) Any unintended discrepancies should be discussed with the physician and any
resulting changes should be documented.
- If the patient is transferred from one unit to another during hospitalization, medications patients
are receiving in the sending unit are reviewed and updated accordingly to reflect the patient's
treatment plan for the new care setting. A review of the medications the patient was taking prior
to admission should also be done to assess if they are still applicable or not for the receiving unit
or new care setting (i.e., to assess if a home medication held upon admission is now appropriate
and could be restarted in the new care setting.) As stated above, any unintended discrepancies
should be discussed with the physician and any resulting changes should be documented.
- To prepare for discharge, the current medication orders are reviewed and compared to the list
of medications the patient was on prior to admission. This comparison (reconciliation) and
assessment helps form the patient's discharge medication list. The patient should be counseled
on any changes, additions or deletions that were made to the medications they were taking prior
to admission. The patient's discharge medication list should also be communicated to the next
provider of service (oftentimes, this will be the primary care physician).
- Although health care professionals are already doing many of these clinical steps, we have
internal and external data to support that medication errors, and in many cases patient harm,
are occurring. We have developed a standardized process for doctors, nurses and pharmacists to
obtain, document and confirm a patient's home medication list. The process ensures that the
most accurate, complete medication history is documented for each patient and that all inpatient
and home medications reconcile.
