What Is Medication Reconciliation? A Plain Guide for Families

Medication reconciliation is the process of comparing a person's current list of medicines with the medicines being ordered at a point of change in their care, such as a hospital admission, a move between wards or discharge home. The aim is to spot and resolve any differences: a medicine left off by accident, the same drug listed twice, a dose that has changed without explanation or a combination that should not be taken together. Doctors, nurses and pharmacists carry it out, but the accuracy of the starting list often depends on patients and families.

When it happens

Reconciliation is meant to take place at every transition of care. Typical moments include:

• admission to hospital, including via the emergency department;
• transfer between units, wards or hospitals;
• discharge home or to a care home or rehabilitation unit;
• the start of a home care service, such as visits from a nurse;
• appointments with a new specialist who prescribes something new.

If your relative is about to begin a service like those described in our guide to home health care, expect the team to ask detailed questions about medicines at the first visit.

The process in four steps

1. Collect the best possible list. Staff gather information from the patient, family, pharmacy and primary care records, and from the containers themselves.
2. Compare. That list is checked against what the new team intends to prescribe.
3. Resolve differences. Each discrepancy is either explained and recorded as intentional, or corrected with the prescriber.
4. Communicate. The updated list is shared with the patient, the family and whoever provides care next.

What it is designed to catch

Some differences are deliberate. A doctor may pause a medicine during an illness or switch to a different one. Reconciliation does not mean every change is wrong, only that every change should be known and explained.

How families can help

Hospital staff are often working from incomplete records, especially in an emergency. Relatives can fill the gaps.

• Keep an up-to-date list with names, strengths, timing and what each medicine is for. Our guide to medication management for elderly parents includes a simple template.
• Bring the containers if you can. Many clinicians call this a "brown bag" check: everything in one bag, so nothing is forgotten.
• Mention what is not on prescription: pain relievers, vitamins, herbal products, creams and eye drops.
• Share allergies and past reactions, and say how your relative actually takes each medicine if that differs from the label.
• Name the pharmacy and prescribers so staff can verify details.

Having the list to hand helps at ordinary appointments too. Our piece on talking to a doctor about memory loss suggests taking it along, since several medicines can affect thinking and alertness.

Questions to ask at discharge

What is new?

Ask the name of each new medicine, what it is for, how long it should be taken and what side effects to watch for.

What has stopped or changed?

Ask which home medicines should not be restarted and why, and which ones have a new dose or timing.

Who do we call with questions?

Get a name or department, a phone number and the date of any follow-up review.

Is reconciliation only for hospital stays?

No. The same comparison is useful whenever a new prescriber is involved, after a routine appointment where doses were adjusted, or when someone moves into a care home. Families can run a simple version themselves by checking the latest letters and labels against the list at home.

After you get home

Update the master list the same day, and give a copy to anyone else who helps. Separate medicines that have been stopped and ask a pharmacist how to dispose of them; our guide to storing medicine at home covers take-back options. Watch your relative closely for the first few days, as new combinations can take time to settle. If anything seems wrong, from new drowsiness to a missed dose you are unsure how to handle, call the pharmacist or the number on the discharge papers rather than guessing.

Clear medicine routines are part of the bigger picture of caring for an older parent at home. A few minutes spent checking the list at each change can prevent a great deal of worry later.
