Risks Associated with Polypharmacy
• Functional status decline
• ADRs
• Inappropriate drug use
• Increased medication administration errors
• Increased risk of geriatric syndromes

Indications for Antipsychotics in the Elderly Nursing Home Patients
1. Disorders such as delirium, schizophrenia,
paraphrenia, dementia
With
2. Thinking and behavior disturbances such as delusions,
hallucinations, paranoia
And
3. Severe enough to be of harm to the patient and/or others
![Page 16: Suboptimal Drug Use in Long Term Care Facility Patients Joseph T. Hanlon PharmD, MS Professor, Departments of Medicine (Geriatrics) and Pharmacy and Therapeutics,](https://reader035.fdocuments.net/reader035/viewer/2022062714/56649cfd5503460f949cdf98/html5/thumbnails/16.jpg)
Antipsychotic Guidelines
in Nursing Home Elderly • Residents should receive gradual dose reductions, behavior
interventions unless clinically contraindicated
• Avoid use of highly anticholinergic antipsychotics (e.g., olanzapine, chlorpromazine, thioridazine, clozapine)
• Specific doses recommended
• Monitor for metabolic and EPS problems

Learning Objectives
At the end of the talk the participants should be able to:• List the different types of suboptimal drug use• Describe the prevalence of polypharmacy (9+ drugs) in
long term care patients• Discuss the underuse of medications in long term care
patients• Summarize drugs that are potentially inappropriate or
unnecessary as per new CMS Guidelines for LTCF • Discuss principles to optimize drug use in long term care
patients
![Page 35: Suboptimal Drug Use in Long Term Care Facility Patients Joseph T. Hanlon PharmD, MS Professor, Departments of Medicine (Geriatrics) and Pharmacy and Therapeutics,](https://reader035.fdocuments.net/reader035/viewer/2022062714/56649cfd5503460f949cdf98/html5/thumbnails/35.jpg)
Principles for Optimizing Drug Use in the Elderly
• Consider whether drug therapy is necessary • Promote the use of a small number of drugs to treat
common problems • Adjust doses and or/dosage intervals for medications • Establish reasonable therapeutic endpoints and monitor for
desired outcome • Monitor for adverse drug reactions • Regularly review the need for chronic medications
![Page 36: Suboptimal Drug Use in Long Term Care Facility Patients Joseph T. Hanlon PharmD, MS Professor, Departments of Medicine (Geriatrics) and Pharmacy and Therapeutics,](https://reader035.fdocuments.net/reader035/viewer/2022062714/56649cfd5503460f949cdf98/html5/thumbnails/36.jpg)

A Model for Appropriate Prescribing for Patients Late in Life
![Page 37: Suboptimal Drug Use in Long Term Care Facility Patients Joseph T. Hanlon PharmD, MS Professor, Departments of Medicine (Geriatrics) and Pharmacy and Therapeutics,](https://reader035.fdocuments.net/reader035/viewer/2022062714/56649cfd5503460f949cdf98/html5/thumbnails/37.jpg)
Chronic Medication Review Steps
• Assess whether ADRs are the cause of any symptoms
• Match problem list with drug list
• If on drug but no match with problem list consider whether drug is necessary
• If has a chronic condition and not on a medication consider whether there is an evidence based drug to tx the condition
• Assess the monitoring for efficacy/safety/appropriateness of the remaining medications
![Page 38: Suboptimal Drug Use in Long Term Care Facility Patients Joseph T. Hanlon PharmD, MS Professor, Departments of Medicine (Geriatrics) and Pharmacy and Therapeutics,](https://reader035.fdocuments.net/reader035/viewer/2022062714/56649cfd5503460f949cdf98/html5/thumbnails/38.jpg)
Assessing Prescribing Appropriateness Using the MAI
• Is there an indication for the drug?
• Is the medication effective for the condition?
• Is the dosage correct?
• Are the directions correct?
• Are the directions practical?
• Are there clinically significant drug-drug interactions?
• Are there clinically significant drug-disease interactions?
• Is there unnecessary duplication with other drugs?
• Is the duration of therapy acceptable?
• Is this drug the least expensive alternative compared to others of equal
utility?
