Compares admission, inpatient, and discharge medication lists to identify discrepancies. Use when performing medication reconciliation, identifying med changes, or verifying discharge prescriptions.
Medication discrepancies at care transitions cause approximately 50% of all hospital medication errors and up to 20% of adverse drug events. Inpatient medication reconciliation is distinct from pharmacy cross-setting reconciliation: it operates within the hospital stay lifecycle across three critical transition points — admission, transfer, and discharge — each with unique failure modes. Unreconciled medications lead to therapeutic duplications, omitted chronic therapies, drug interactions, and preventable readmissions. Joint Commission NPSG.03.06.01 mandates reconciliation at every transition of care. This skill enforces a structured, auditable process that catches discrepancies before they reach the patient.
Before beginning reconciliation, collect and confirm the following. Do NOT proceed until every required item is addressed or explicitly marked unavailable.
| Transition | Source List | Target List |
|---|
| Key Risk |
|---|
| Admission | Best Possible Medication History (BPMH) | Admission orders | Omission of chronic meds; inappropriate continuation of home meds |
| Transfer | Sending-unit MAR | Receiving-unit orders | IV-to-PO conversion failures; dose drift from organ function changes |
| Discharge | Active inpatient MAR | Discharge prescriptions | Held meds not restarted; new meds missing from Rx; duplications |
State the transition type explicitly in all output.
Required sources (mark [UNAVAILABLE] if absent — never silently omit):
Flag any of the following — each increases reconciliation error probability:
High-risk medication classes (require line-by-line verification):
| Class | Examples | Specific Risk |
|---|---|---|
| Anticoagulants | warfarin, DOACs, heparin, enoxaparin | Bleeding / thrombosis if omitted or duplicated |
| Insulin / diabetes agents | insulin (all types), sulfonylureas, SGLT2i | Hypo/hyperglycemia; sulfonylureas often held inpatient |
| Cardiac medications | beta-blockers, antiarrhythmics, digoxin | Rebound tachycardia, arrhythmia if abruptly stopped |
| Seizure medications | levetiracetam, phenytoin, valproic acid | Seizure breakthrough; narrow therapeutic indices |
| Immunosuppressants | tacrolimus, mycophenolate, cyclosporine | Rejection / toxicity; level-dependent dosing |
| Opioids / controlled substances | oxycodone, methadone, buprenorphine | Withdrawal; diversion risk; dose conversion errors |
| Corticosteroids | prednisone, hydrocortisone, dexamethasone | Adrenal crisis if abruptly stopped after prolonged use |
For every medication on every source list, capture these seven fields. Missing fields get [VERIFY].
| Field | Description |
|---|---|
| Medication | Generic name (note brand if relevant for narrow therapeutic index) |
| Dose | Numeric dose with unit |
| Route | PO, IV, SQ, IM, topical, inhaled, etc. |
| Frequency | Specific schedule (not just "as directed") |
| Indication | Why the patient takes it — required for disposition decisions |
| Status | Active, held, discontinued, new, changed |
| Source | Which list(s) this medication appears on |
Align medications across source and target lists. For each medication, assign one disposition:
| Disposition | Definition | When to Use |
|---|---|---|
| Continued | Same med, dose, route, frequency | No change needed across transition |
| Modified | Same med, different dose/route/frequency | Dose adjustment, IV→PO conversion, frequency change |
| Substituted | Different med, same therapeutic class | Formulary swap (e.g., home atorvastatin → hospital rosuvastatin) |
| Held | Intentionally paused | NPO status, perioperative, acute kidney injury, etc. |
| Discontinued | Stopped permanently | No longer indicated, adverse effect, therapeutic change |
| Omitted | On source list but absent from target with no documented reason | This is the primary error to catch |
| New | On target list but not on source | Started during this encounter |
For every discrepancy found, document:
| Field | Content |
|---|---|
| Medication | Drug name and dose |
| Discrepancy type | Omission, duplication, dose mismatch, route mismatch, interaction, unaddressed hold |
| Source | Which list(s) show the conflict |
| Severity | Critical (high-risk class or immediate harm potential), Major (clinical significance), Minor (documentation gap) |
| Recommended action | Specific resolution with rationale |
| Status | Open, resolved, escalated |
Produce the final reconciled list using the template in references/INPATIENT-MED-REC-TEMPLATE.md. Every medication on the final list must have all seven fields populated. No [VERIFY] tags may remain in the final output — unresolved items must be escalated.
MEDICATION RECONCILIATION — [TRANSITION TYPE]
Patient: [ID/Name] Date: [YYYY-MM-DD]
Transition: [Admission / Transfer (from → to) / Discharge]
Total Source Medications: [N] Total Target Medications: [N]
Discrepancies Found: [N] (Critical: [N] | Major: [N] | Minor: [N])
High-Risk Classes Present: [list]

When reconciliation accompanies a handoff, structure the medication summary using I-PASS:
| Element | Medication Reconciliation Content |
|---|---|
| Illness severity | Patient acuity and medication complexity tier |
| Patient summary | Key diagnoses driving medication regimen |
| Action list | Discrepancies requiring resolution; pending medication decisions |
| Situation awareness | High-risk medications; drug levels pending; renal function trend |
| Synthesis | Anticipated medication changes in next 12-24 hours |
After generating the reconciled list, verify every item below. Do not finalize until all pass.
[VERIFY] tags resolved or escalated to human review| Standard | Requirement | How This Skill Addresses It |
|---|---|---|
| Joint Commission NPSG.03.06.01 | Maintain accurate medication list; reconcile at transitions | Structured reconciliation at admission, transfer, discharge |
| CMS CoP §482.24(c) | Medication orders reviewed for appropriateness | Disposition table with indication and rationale |
| WHO High 5s: Medication Reconciliation | Systematic BPMH; compare against orders | BPMH as mandatory source; cross-reference workflow |
| Error Type | Detection Method |
|---|---|
| Omission of chronic med | Source-to-target gap analysis (Step 2, "Omitted" disposition) |
| Therapeutic duplication | Same-class check across all lists |
| Dose/route mismatch | Field-by-field comparison in normalization (Step 1) |
| Held med not restarted at discharge | Discharge-specific check (Step 3, Discharge section) |
| IV med on discharge Rx | Route validation against care setting |
| Formulary swap without dose equivalence | Substitution verification (Step 2, "Substituted" disposition) |
| Drug-drug interaction introduced | New-medication interaction screen |
