Quality indicators for appropriate medication use in vulnerable older adults

Quality indicators for appropriate medication use in vulnerable older adults
Indicator title Description Rationale
Medication list An up-to-date medication list that includes over-the-counter medications should be accessible to all health care providers in the medical record. Enables identification of potential drug-related causes of new symptoms, eliminates inappropriate duplications, allows review for drug-drug interactions, and allows streamlining of regimen to improve adherence.
Annual drug regimen review All vulnerable older adults should have an annual drug regimen review. Allows an opportunity for discontinuing unnecessary medications, or addition of necessary drugs that are not currently prescribed.
Drug indication All drugs prescribed for vulnerable older adults should have a clearly defined indication. Allows discontinuing medications that may have been prescribed for unclear or transient indications.
Patient education All vulnerable older adults (or caregivers) should receive appropriate education about the use of any prescribed drug. Education may improve adherence and clinical outcomes; also can alert patients or caregivers to potential adverse effects.
Response to therapy Response to therapy should be documented for all ongoing medical conditions. Documenting response will help clarify whether a drug is meeting the therapeutic goal for which it was prescribed and provides a basis for continuation, modification, or discontinuation.
Education for warfarin therapy Patients newly prescribed warfarin should receive education about diet, drug interactions, and risk of bleeding, or should be referred to an anticoagulation clinic. Awareness of drugs and dietary substances that interact with warfarin can decrease the risk of bleeding complications.
Monitoring warfarin therapy When warfarin is prescribed, INR should be determined within 4 days of initiation of therapy and at least every 6 weeks therafter.* Older adults are at high risk for drug toxicity, and close monitoring can help maintain the INR within the therapeutic range.
Monitoring ACE inhibitor therapy When ACE inhibitor therapy is prescribed, a serum creatinine and potassium should be monitored within 2 weeks after initiation of therapy and at least yearly thereafter. Older adults are at increased risk of renal insufficiency and hyperkalemia.
Monitoring loop diuretic therapy When loop diuretic therapy is prescribed, electrolytes should be checked within 2 weeks after initiation and at least annually. Risk of hypokalemia due to diuretic therapy.
Avoid propoxyphene Do not prescribe propoxyphene as an analgesic agent. Propoxyphene is inferior to, or at best equivalent to, acetaminophen or other analgesics with better safety profiles.
Avoid chronic or high-dose benzodiazepine use If a benzodiazepine is taken for more than 1 month, there should be documentation of discussion of risks and attempt to taper or discontinue. Benzodiazepines increase the risk of falls, hip fracture, and confusion.
Avoid drugs with strong anticholinergic properties Do not prescribe drug therapies with a strong anticholinergic effect if alternative therapies are available. These therapies are associated with adverse events such as confusion, urinary retention, constipation, visual disturbance, and hypotension.
Avoid barbiturates If an older adult does require the therapy for control of seizures, do not use barbiturates. These therapies are potent central nervous system depressants, have a low therapeutic index, are highly addictive, cause drug interactions, and are associated with an increased risk for falls and hip fracture.
Avoid meperidine as an opioid analgesic When analgesia is required, avoid use of meperidine. This therapy is associated with an increased risk for delirium and may be associated with the development of seizures.
Avoid chronic use of ketorolac Ketorolac should not be prescribed for more than 5 days. This therapy is associated with a high risk of GI side effects, including bleeding, and other analgesics are safer in older patients.
Avoid skeletal muscle relaxants Skeletal muscle relaxants (cyclobenzaprine, methocarbamol, carisoprodol, chlorzoxazone, orphenadrine, tizanidine, metaxalone) should not be prescribed for more than 1 week. These medications can cause anticholinergic adverse effects, sedation, confusion, and data of efficacy are limited.
Avoid ticlopidine Clopidogrel should be prescribed rather than ticlopidine for patients who require antiplatelet therapy (eg, recent stroke, myocardial infarction, acute coronary syndrome, percutaneous angioplasty). Ticlopidine may be less effective than clopidogrel and is associated with a higher risk of hematological disorders than clopidogrel.
Treat iron deficiency anemia with low-dose oral iron therapy Vulnerable older adults with iron deficiency anemia should take no more than 1 low-dose oral iron tablet daily. Low-dose therapy is equally effective with fewer adverse effects than high-dose oral iron therapy.
Antipsychotic medication response An assessment of response should be documented within 1 month for older adults started on an antipsychotic drug. The use of antipsychotic drugs increases mortality in older adults, and behavioral modification is an effective alternative.
Acetaminophen Older adults prescribed high-dose (≥3 g per day) acetaminophen, or those with liver disease taking acetaminophen chronically, should be advised of the risk of liver toxicity. The risk of liver toxicity is greater with use of acetaminophen.
NSAIDs and aspirin

The risk of GI bleeding should be discussed and documented.

Individuals at increased risk for GI bleeding (age >75 years, peptic ulcer disease, history of GI bleeding, warfarin use, chronic glucocorticoid use) should be treated concomitantly with misoprostol or a proton pump inhibitor when treated with a nonselective NSAID.
Risks of GI bleeding are increased in older adults taking NSAIDs or daily aspirin.
INR: international normalized ratio; ACE: angiotensin-converting enzyme; GI: gastrointestinal; NSAIDs: nonsteroidal antiinflammatory drugs.
* These monitoring frequencies represent minimal indications; many experts would advise daily monitoring initially and monitoring every four weeks once a stable and at-goal therapeutic INR has been achieved.
