Avoid the ED
Dr. Goel said doctors should avoid sending patients to the emergency department, an often chaotic place that is especially unfriendly to centenarians and the very old. “Sometimes I’ve seen older patients who are being rushed to the ER, and I ask, What are the goals of care?” she said.
Clinicians caring for seniors should keep in mind that infections can cause seniors to appear confused – and this may lead the clinician to think the patient has dementia. Or, Dr. Goel said, a patient with dementia may suddenly experience much worse dementia.
“In either case, you want to make sure you’re not dealing with any underlying infection, like urinary tract infection, or pneumonia brewing, or skin infections,” she said. “Their skin is so much frailer. You want to make sure there are no bedsores.”
She has had patients whose children report that their usually placid centenarian parents are suddenly acting out. “We’ll do a urinary test and it definitely shows a urinary tract infection. You want to make sure you’re not missing out on something else before you attribute it to dementia,” she said.
Environmental changes, such as moving a patient to a new room in a hospital setting, can trigger an acute mental status change, such as delirium, she added. Helping older patients feel in control as much as possible is important.
“You want to make sure you’re orienting them to the time of day. Make sure they get up at the same time, go to bed at the same time, have clocks and calendars present – just making sure that they feel like they’re still in control of their body and their day,” she said.
Physicians should be aware of potential depression in these patients, whose experience of loss – an unavoidable consequence of outliving family and friends – can result in problems with sleep and diet, as well as a sense of social isolation.
Neal Flomenbaum, MD, professor and emergency physician-in-chief emeritus, New York–Presbyterian/Weill Cornell Medical Center in New York, said sometimes the best thing for these very elderly patients is to “get them in and out of ED as quickly as possible, and do what you can diagnostically.”
He noted that EDs have been making accommodations to serve the elderly, such as using LEDs that replicate outdoor lighting conditions, as well as providing seniors with separate rooms with glass doors to protect them from noise, separate air handlers to prevent infections, and adequate space for visitors.
These patients often are subject to trauma from falls.
“The bones don’t heal as well as in younger people, and treating their comorbidities is essential. Once they have trouble with one area and they’re lying in bed and can’t move much, they can get bedsores,” Dr. Flomenbaum said. “In the hospital, they are vulnerable to infections. So, you’re thinking of all of these things at the same time and how to treat them appropriately and then get them out of the hospital as soon as possible with whatever care that they need in their own homes if at all possible.”
“I always err on the side of less is more,” Dr. Goel said. “Obviously, if there is something – if they have a cough, they need an x-ray. That’s very basic. We want to take care of that. Give them the antibiotic if they need that. But rushing them in and out of the hospital doesn’t add to their quality of life.”
Dr. Flomenbaum, a pioneer in geriatric emergency medicine, says physicians need to be aware that centenarians and other very old patients don’t present the same way as younger adults.
He began to notice more than 20 years ago that every night, patients would turn up in his ED who were in their late 90s into their 100s. Some would come in with what their children identified as sudden-onset dementia – they didn’t know their own names and couldn’t identify their kids. They didn’t know the time or day. Dr. Flomenbaum said the children often asked whether their parents should enter a nursing home.
“And I’d say, ‘Not so fast. Well, let’s take a look at this.’ You don’t develop that kind of dementia overnight. It usually takes a while,” he said.
He said he ordered complete blood cell counts and oxygen saturation tests that frequently turned out to be abnormal. They didn’t have a fever, and infiltrates initially weren’t seen on chest x-rays.
With rehydration and supplemental oxygen, their symptoms started to improve, and it became obvious that the symptoms were not of dementia but of pneumonia, and that they required antibiotics, Dr. Flomenbaum said.
