Medication Risk Assessment for Your Patient

Yes, I can systematically evaluate your patient's medication list for potential risks including drug-drug interactions, drug-disease interactions, polypharmacy burden, and potentially inappropriate medications—this structured review is essential for preventing adverse drug events, hospitalizations, and falls. 1

How to Submit Your Patient's Medications

To perform a comprehensive medication risk assessment, provide the following information:

  • Complete medication list including all prescription medications with doses and frequencies 1
  • Over-the-counter medications, supplements, and herbal remedies 2
  • Patient's age (particularly important if ≥65 years) 1
  • Active medical diagnoses (comorbid conditions) 1, 2
  • Renal and hepatic function if available 3
  • Known drug allergies or previous adverse reactions 1, 3
  • Recent medication changes (within past 28 days) 4

What I Will Assess

1. Polypharmacy Burden

  • Flag if taking ≥5 medications (50-60% chance of drug-drug interaction with 5 medications; 90% chance with ≥10 medications) 1
  • Polypharmacy increases risk of hospitalization, early treatment discontinuation, adverse drug events, and functional decline 1

2. Drug-Drug Interactions

  • QT prolongation risks from medication combinations 1, 2
  • Anticoagulant interactions and bleeding risk 1
  • Serotonin syndrome potential from combinations of antidepressants, opioids, or other serotonergic agents 1, 5
  • Cytochrome P450 interactions (common with opioids, antidepressants, antibiotics, antipsychotics) 1
  • Lithium interactions (e.g., with ACE inhibitors like lisinopril) that increase toxicity risk 5

3. Drug-Disease Interactions

  • NSAIDs in heart failure, chronic kidney disease, or hypertension 1, 2
  • Anticholinergics in cognitive impairment 1
  • Sulfonylureas in chronic kidney disease (hypoglycemia risk) 1

4. High-Risk Medications in Older Adults (Beers Criteria/STOPP)

  • Sedatives/hypnotics, benzodiazepines, anxiolytics (fall risk, cognitive impairment) 1, 2
  • Opioids (fall risk, respiratory depression) 1, 2
  • Anticholinergics including diphenhydramine (delirium, falls, urinary retention) 1
  • Hypoglycemic agents particularly sulfonylureas (severe hypoglycemia risk) 1, 2
  • First-generation antihistamines 1

5. Medication Duplication

  • Identify duplicate therapies or medications with additive side effects resulting in toxicity 1
  • Concomitant therapy that may be redundant 1

6. Potentially Inappropriate Dosing

  • Renal dose adjustments needed for medications cleared by kidneys 1, 3
  • Hepatic dose adjustments for medications metabolized by liver 1
  • Age-related dosing considerations 1

7. Medication Underuse (START Criteria)

  • Missing indicated medications such as statins in coronary artery disease, antiplatelet agents after stenting 1
  • Undertreated conditions that may have been overlooked in complex regimens 1

8. Specific High-Risk Drug Classes

The following medication classes warrant particular scrutiny: 3

  • Anticoagulants/thrombolytics (bleeding risk)
  • Antimicrobials (interactions, resistance)
  • Cardiovascular agents (hypotension, arrhythmias)
  • Central nervous system agents (falls, altered mental status)
  • Insulin/hypoglycemics (hypoglycemia)
  • Diuretics (electrolyte abnormalities)
  • Corticosteroids (multiple adverse effects)
  • Opiates (respiratory depression, falls)
  • Anti-epileptics (drug interactions)

Clinical Outcomes I'm Protecting Against

The primary adverse outcomes associated with medication risks include: 6, 7

  • Frequent falls (66% increased risk with potentially inappropriate medications/drug interactions) 6
  • Hospital admissions (29% increased risk) 6
  • Emergency department visits 1, 4
  • Adverse drug events causing morbidity and mortality 1, 7
  • Functional decline and geriatric syndromes 1
  • Medication nonadherence due to complexity 1

What Happens After the Assessment

Based on the medication review, I will provide: 1, 2

  • Specific medications to consider deprescribing (those where harm outweighs benefit)
  • Dose adjustments needed for safety
  • Alternative medications with lower risk profiles
  • Monitoring parameters required for high-risk medications
  • Simplification strategies to reduce pill burden and improve adherence
  • Recommendations for physician follow-up on specific concerns

Submit your patient's complete medication list and clinical information, and I will provide a detailed, actionable risk assessment with specific recommendations prioritizing your patient's safety and quality of life. 1, 2
