Nursing Home Medication Review: What the Consultant Pharmacist Does
A nursing-home resident may take medications prescribed by several clinicians.
Federal nursing-home rules add an important safety layer: a licensed pharmacist must review each resident’s drug regimen at least monthly in Medicare- and Medicaid-certified nursing facilities.
This consultant-pharmacist review is not the same thing as simply filling prescriptions.
The purpose is to identify medication irregularities and help the clinical team review whether the resident’s medication regimen remains appropriate.
What federal rules require
Under 42 CFR §483.45, the facility must provide pharmacy services and employ or obtain the services of a licensed pharmacist.
The pharmacist must review each resident’s drug regimen at least once a month.
The pharmacist reports irregularities to the attending physician, the facility’s medical director, and the director of nursing.
The regulation also requires the attending physician to document that identified irregularities were reviewed and what action was taken, unless no change is clinically necessary.
What an “irregularity” might involve
A pharmacist may identify concerns involving:
- unnecessary medications;
- duplicate therapy;
- excessive dose;
- excessive duration;
- medication interactions;
- adverse effects;
- missing clinical indication;
- monitoring needs;
- psychotropic medication requirements;
- antibiotic use; or
- other medication-related risks.
The pharmacist does not independently change every prescription.
The prescriber and clinical team remain involved in treatment decisions.
Ask what happens after the pharmacist makes a recommendation
Families may assume a pharmacist recommendation automatically changes the medication list.
Ask:
- What did the pharmacist identify?
- Who reviewed the recommendation?
- Did the prescriber agree?
- If the medication was continued, what was the clinical rationale?
- When will it be reassessed?
- What monitoring is required?
A documented review can be appropriate even when the medication is not changed.
Psychotropic medications deserve special attention
Federal nursing-home rules include additional requirements for psychotropic medications.
These drugs should not be used simply for staff convenience.
Ask about:
- target symptom;
- diagnosis or clinical rationale;
- non-drug approaches;
- dose;
- side effects;
- gradual dose reduction when required and clinically appropriate; and
- monitoring.
Our guide Antipsychotic Medication in Dementia Care explains this issue in more detail.
Antibiotic stewardship is part of medication safety
CDC recommends antibiotic-stewardship programs in nursing homes.
Consultant pharmacists can support appropriate antibiotic use by helping facilities review:
- indication;
- drug choice;
- duration;
- dose;
- interactions; and
- monitoring.
Antibiotics can be lifesaving, but unnecessary or inappropriate use creates avoidable risk.
Families can help by keeping outside medication changes visible
Medication problems often occur after:
- hospitalization;
- specialist visit;
- emergency-department visit;
- dialysis;
- surgery; or
- a move between facilities.
Tell the nursing home when an outside clinician changes a prescription.
Ask which current medication list is considered authoritative.
Our guide How to Organize an Older Parent’s Medication List Before a Move can help.
Watch for changes after a new medication begins
Tell staff or the clinician if you notice:
- unusual sleepiness;
- new confusion;
- dizziness;
- repeated falls;
- appetite change;
- constipation;
- tremor;
- swallowing difficulty;
- rash; or
- another new symptom.
Do not stop prescription medications on your own.
The family’s role is to notice and communicate changes.
A practical example
Maria’s father begins falling more often after a hospital stay.
His medication list now includes two drugs that can lower blood pressure.
At the monthly drug-regimen review, the consultant pharmacist flags the combination for clinical review.
The physician evaluates the medications, blood pressure, and fall pattern and adjusts the plan.
The pharmacist did not diagnose the cause of every fall. The review helped trigger a structured medication-safety check.
Eight questions to ask about medication review
- Who is the facility’s consultant pharmacist?
- Is each resident’s regimen reviewed at least monthly?
- How are pharmacist recommendations documented?
- Who reviews the recommendations?
- How are medication changes communicated to family?
- How are psychotropic medications monitored?
- How does the facility handle antibiotic stewardship?
- How are medications reconciled after hospital or specialist visits?
