Elderly patients are taking too many drugs. And, in most cases the drugs can be stopped. This surprising idea was highlighted by Dr. Ezekiel J. Emanuel in his New York Times article 11/22/15. He backed up his statements with a study from 2010 (JAMA). The figures that follow are from that study.
The first figure is the logic diagram for stopping medications in elderly patients who have several chronic diseases. The second figure is the list of medications that were stopped in the study. Only 2% of the stopped medications eventually had to be restarted. The cost savings alone is huge and the reduction in the risk of side effects is likewise tremendous. “Less is more”.
Health care providers often prescribe drugs intended for younger healthier patients to older sicker patients. Often the drug testing originally done to approve drugs excludes older sicker patients due to the risks of side effects. A drug might add many years of life to a 50 year old but that’s not likely for an 80 year old with multiple problems. In fact, over medicating elderly patients may hasten death — this has been proven in many studies.
Dr Ezekiel suggests asking the following questions to the health care providers who prescribe medications, tests or treatments to elderly patients (or perhaps any patients):
- What difference will it make?
- How much improvement is expected?
- How likely and severe are the side effects?
Evaluate the answers carefully, if the answers are: small difference, not much improvement, and fairly likely side effects then perhaps that drug, test or treatment is not needed.
Dr. Emanuel favors the advice of teaching hospital doctors like him, but it’s just not practical or necessary for patients to get a university consultation. Stopping medications is not rocket science. As the graphic says, it may be better for many elderly patients to get “hugs not drugs“.
Too much treatment is dangerous just like too little treatment. Treating blood pressure too early or too aggressively increases the risk of death. Treating elderly patients with diabetes with too much medicine increases episodes of low blood sugar that damage the brain and leads to broken bones from falling.
In 2014 the national guidelines for blood pressure treatment were changed to allow a higher blood pressure. Similarly, a recent study found increased mortality for elderly patients treated too strongly for diabetes.
This is not rocket science. Imagine a blood pressure medication that could lower the blood pressure to any level. Knowing that zero blood pressure means you are dead, it stands to reason there is a point where treating blood pressure goes from helpful to dangerous. Same for blood sugar.
Sometimes this problem is called “treating the test“. In essence prescribers just look at the numbers and write a prescription, but ignore symptoms of weakness or spells of altered consciousness. Hypertension and diabetes are good examples but this happens with lots of other conditions.
Examples of over-treatment include treating a sore throat with antibiotics, treating mild asthma with oral steroids, or treating an elevated lyme serology test with antibiotics. It takes time to make a correct diagnosis and time to explain treatment to patients — some health care providers simply don’t take the time to do either.
Most drugs have a “therapeutic window“. As long as the window is open the patient gets benefit. But, the window closes due to side effects and advanced age.
If a person is over 80 or in poor health excessive medical treatment is a substantial risk. In this group even the thought of a low cholesterol diet is foolhardy. It’s all about risks and benefits.
