The Joint Commission recognizes that many patients may be too ill, injured, young, or disabled to actively participate in the medication reconciliation process. In addition, patients may need the assistance of another person (e.g., family member, significant other, surrogate decision maker) if they are overwhelmed in managing their condition, are not proficient in speaking or reading English, or face health literacy challenges that might prevent them from understanding medication use directions. Therefore, the following addition should be included in the section titled “Joint Commission requirements and recommendations.” Addendum to Sentinel Event Alert #35, Using medication reconciliation to prevent errors (#4) When the patient is unable to actively or fully participate in the medication reconciliation process and has requested assistance from another person(s) (e.g., family member, significant other, surrogate decision maker), involve the authorized person(s) in the medication reconciliation process. This involvement should occur at all interfaces of care, and on admission to and discharge from the facility.
