9.2 Medication Therapy Review (MTR)

9.2 Medication Therapy Review (MTR)

Quick Answer: An MTR systematically collects patient information, assesses therapies, builds a prioritized MRP list, and plans resolution. Comprehensive MTR looks at the whole regimen; targeted MTR focuses on a specific problem. Technicians gather and organize; pharmacists assess and decide.

The Medication Therapy Review (MTR) is the first core element and the clinical heart of MTM. Without a real review, the PMR is just a list and the MAP is guesswork. Domain 3 expects you to know what an MTR is, how comprehensive and targeted reviews differ, and where the technician’s work stops and the pharmacist’s assessment begins.

Definition: What an MTR Includes

In the APhA/NACDS model, an MTR is a systematic process of:

1. Collecting patient-specific information
2. Assessing medication therapies to identify medication-related problems
3. Developing a prioritized list of medication-related problems
4. Creating a plan to resolve them

MTRs may be delivered face-to-face, by phone, or by other interactive telehealth methods allowed by the program. The defining feature is interactive clinical review, not a silent chart glance with no patient engagement when a comprehensive review is required.

Comprehensive vs. Targeted MTR

Exam tip: “Comprehensive” does not mean “the technician assesses everything clinically.” It means the review covers the full regimen. “Targeted” does not mean “unimportant”—a targeted review of bleeding risk on anticoagulants can be life-critical.

When each type fits

• Comprehensive: patient with multiple chronic diseases and many medications; recent hospital discharge with regimen changes; first MTM enrollment encounter requiring a CMR.
• Targeted: PDC drop on a statin; possible duplicate ACE inhibitor + ARB; new potassium result while on spironolactone; patient reports stopping insulin because of cost.

What Technicians Gather (Data Package for the MTR)

Technicians make or break MTR quality by the completeness and organization of the intake package. Collect and organize:

Medication history

• Prescription medications from all pharmacies (including mail order and specialty)
• Strengths, directions, routes, and how the patient actually takes each drug
• Start dates / stop dates when known; PRN patterns
• Samples, borrowed medications, and medications in pill organizers
• OTCs (pain relievers, antacids, antihistamines, sleep aids)
• Herbals, vitamins, minerals, and dietary supplements

Safety and response history

• Allergies vs intolerances / side effects (describe the reaction)
• Past adverse drug reactions
• Vaccination history when relevant to the encounter

Medical and social context

• Chronic and acute conditions (patient-friendly language is fine in intake notes)
• Prescribers and care settings (PCP, specialists, recent ED/hospital)
• Social history that affects use: alcohol, tobacco, living situation, caregiver support, health literacy barriers, cost concerns, work shifts that disrupt dosing

Adherence and access clues

• Missed doses and reasons (forgetfulness, side effects, cost, confusion)
• Recent gaps visible in refill history (flag for pharmacist—do not invent clinical conclusions)
• Barriers: transportation, prior authorizations, formulary issues

Objective data already available

• Recent vitals or labs on file (A1C, potassium, blood pressure, INR, etc.)—present them; do not interpret beyond your role
• Hospital discharge medication lists for reconciliation

Technician gathering checklist

• Asked about OTCs/herbals/supplements explicitly
• Separated allergy from intolerance language when patient describes reactions
• Noted actual use vs labeled directions when they differ
• Listed all pharmacies/sources of medication
• Flagged high-risk discrepancies for pharmacist attention
• Organized a draft medication list ready for MTR assessment

Trap: “We already have claims data, so skip the interview.” Claims miss OTCs, cash-pay fills elsewhere, samples, and real-world adherence behavior.

What Pharmacists Assess During the MTR

The pharmacist (or other qualified provider) uses the data package to evaluate therapy systematically. A common clinical frame is:

From that assessment, the pharmacist:

1. Identifies medication-related problems
2. Prioritizes them (bleeding risk usually outranks a minor duplicate vitamin)
3. Selects interventions (education, therapy recommendations, monitoring) and/or referrals
4. Determines what belongs on the patient-facing MAP
5. Ensures the PMR reflects the reconciled regimen

Technicians may notice patterns (“two NSAIDs listed”) and flag them. Final MRP identification and prioritization remain clinical.

How MTR Connects to Other Core Elements

Realistic MTR Scenarios

Scenario A — Comprehensive review after discharge

Mr. Lopez was discharged with new heart-failure medications. The technician reconciles discharge list, community fills, and OTC ibuprofen the patient still takes for knee pain. The pharmacist’s comprehensive MTR prioritizes NSAID risk with heart failure and diuretics, updates the PMR, places “stop ibuprofen; use acetaminophen as directed” style actions on the MAP after clinical counseling, and documents prescriber communication.

Scenario B — Targeted adherence review

A queue alert shows Ms. Chen’s statin PDC below goal. The technician confirms the patient stopped the drug after muscle aches and never told the clinic. The pharmacist performs a targeted MTR on statin intolerance, considers alternatives/monitoring, and documents follow-up—without needing a full annual CMR that day (program rules permitting).

Scenario C — Role boundary

A technician sees two anticoagulants on the draft list. Correct action: flag and escalate before the review finishes. Incorrect action: tell the patient to stop one anticoagulant during intake.

Scenario D — Incomplete collection sinks the MTR

Intake lists only profile Rx drugs. Mid-review the patient mentions St. John’s wort. The MTR must pause to update the medication history—proving why technician probing for supplements is part of MTR quality.

CMR/TMR Language vs. MTR Language

For exam and workplace fluency:

• MTR = core-element name for the review process (comprehensive or targeted).
• CMR = program term (especially Medicare Part D) for an interactive comprehensive review with a written summary.
• TMR = program term for ongoing targeted reviews addressing specific problems or monitoring needs.

Think: CMR/TMR are how many plans operationalize comprehensive and targeted MTRs. Later chapters detail CMR written summaries, quarterly TMR expectations, and billing timelines. Here, master the review logic and your support role.

Quick self-check

• Can you define MTR in one sentence without using only the letters?
• Can you contrast comprehensive vs targeted with one example each?
• Can you list five history elements technicians must gather?
• Can you name four domains pharmacists assess?

If yes, you are ready for PMR and MAP deep dives that turn MTR findings into patient tools.
