Polypharmacy Discharge: Your Best Med Rec Step
Managing multiple medications after hospital discharge creates real risks for patients and their families. Getting medication reconciliation right at this critical transition point can prevent dangerous drug interactions and reduce readmissions. This article shares practical strategies from healthcare professionals who specialize in safe discharge planning and medication management.
Link Each Pill to Purpose
The "Physical Identification and Purpose Link" teach-back step is an effective technique for helping patients manage polypharmacy. I did not limit my interaction with the patient by reviewing just a list of medications on a piece of paper. When preparing the patient for discharge, it's a good idea to have the patient pick up the medication bottles (or point to their medication list) and explain, in their own words, what each medication is for and when they plan to take it. The "Physical Identification and Purpose Link" teach-back step allows the patient to actively participate in creating a cognitive connection between the physical medication and its clinical purpose. Identifying which medications are "new," "dose changed," and "discontinued" also gives an opportunity to correct any misunderstandings they might have about their polypharmacy that could lead to medication-related problems in the future.
For example, when using the "Physical Identification" step of the teach-back method, you might notice a patient holding both their old lisinopril and new ACE inhibitor. By identifying the duplication of therapy, you can save the patient from a severe episode of hypotension or acute kidney injury, which could have resulted in an ER visit. Performing this simple checklist step not only allows the patient to indicate that they "understand" their discharge instructions, but more importantly, it enables the patient to demonstrate the ability to safely manage a complex medication regimen.

Deprescribe Duplicates and Low-Value Drugs
Removing duplicate and low-value drugs is a high-yield step at discharge. Therapeutic duplications hide in drug classes, combination products, and PRN items, and they drive harm without added benefit. Each medicine should have a current indication, a clear goal, and evidence that it helps more than it hurts.
When these are missing, deprescribing lowers pill burden, cuts costs, and reduces confusion. Invite the patient and caregiver to agree on what truly matters and stop the rest safely. Begin a targeted deprescribing review before the patient leaves.
Recalibrate Doses to Organ Function
Right dosing depends on kidney and liver function, and discharge is the moment to recalibrate. Use the most recent labs to estimate renal clearance and hepatic function, and match doses and intervals to those values. Watch narrow-therapeutic-index drugs, such as anticoagulants and antiepileptics, which can tip from safe to toxic with small changes.
Consider dialysis timing, fluid shifts, and acute kidney injury recovery when setting the first outpatient dose. Set follow-up labs and a clear plan to adjust if values change after discharge. Recalculate and document every dose today.
Screen Interactions and Allergies Before Release
Interaction screening protects patients from preventable harm after discharge. Check for drug-drug, drug-disease, and drug-food conflicts, and include over-the-counter products, herbals, and supplements. Respect known allergies and likely cross-reactions, and record the reaction type to guide safe choices.
Prioritize clinically significant interactions and offer safer alternatives or monitoring plans when the pair cannot be avoided. Share the final plan with the patient in simple language so warning signs are clear. Run a full interaction and allergy check before sending the prescription list.
Specify Stop Dates and PRN Rules
Clear stop dates and PRN directions turn a good plan into a safe plan. Every time-limited drug needs an end date, and taper schedules must be written out to prevent confusion. PRN items should name the symptom they treat, the dose, the frequency, and the maximum in a day.
Patients also need rules for when not to take a PRN, such as when similar drugs are already on board or when pain scales are low. These details cut errors, improve control of symptoms, and reduce readmissions. Write explicit stop dates and PRN instructions now.
Share One Reconciled List Across Teams
Sharing the reconciled medication list across all care settings closes the loop. The list should state each drug, its purpose, any changes made, and the reason for those changes in terms that patients understand. Send it to the primary clinician, specialists, the community pharmacist, and any home health or facility team.
Provide the patient and caregiver with the same list, and confirm understanding with teach-back to catch errors early. Update the electronic record and the health information exchange so everyone sees one source of truth. Send the complete reconciled list to every involved team before discharge.
