Flu Shots for Older Adults During COVID Times: What to Know & Do for 2020

Usually, I update this article in October, which I think of as flu vaccination time.

But this is 2020 and things are different, so I am writing this in September. In particular, due to COVID-19, the Centers for Disease Control (CDC) is urging that people get vaccinated against influenza early in the fall (before the end of October 2020).

Vaccination against seasonal influenza has always been a bit of a tricky topic. Many older adults are skeptical of the need to get a yearly vaccination against influenza. They aren’t sure it will help. Or they think that the vaccination will actually give them a mild case of the flu. Or they just don’t like needles.

Or maybe they aren’t sure which type of seasonal flu shot to get: the regular one or one of the newer “stronger” versions, designed for older adults?

And now that we have COVID-19 to contend with, vaccination for seasonal influenza might feel even more confusing for people.

Don’t let yourself be confused. In this article, I will share with you what I know about influenza vaccination and what I’ve learned about influenza in COVID times. I also have updates on the newest high-dose vaccines available for older adults.

But let me share the bottom line with you right now. In general, I have always supported the CDC’s usual recommendation that everyone over the age of 6 months should get their seasonal flu shot.

This year, I agree with the CDC that it’s especially important for people to get their seasonal flu shot, as soon as you can, and if you are an older adult, I recommend getting one of the higher-dose vaccines.

In “normal” pre-COVID times, the Centers for Disease Control (CDC) estimates that every year, influenza affects 9-45 million Americans, causes 140,000-810,100 hospitalizations, and results in 12,000-61,000 deaths. In most years, influenza vaccination does help reduce hospitalizations and deaths (I go into details below).

And now this fall, we will also have COVID-19 to contend with. As of September 2020, at least 190,000 Americans have died of this disease. We don’t know for sure what will happen this fall, but since COVID seems to spread more when people are indoors and in proximity to the exhalations of others, COVID is likely to get worse this fall.

So this year, more than ever, it’s important to do what you can to reduce respiratory illness, to protect yourself, and to protect others. We don’t yet have a COVID vaccine, but we do have influenza vaccines.

In fact, I’m about to go get mine. As a healthy woman in her 40s, I’m not that concerned about getting dangerously ill from influenza. Instead, I get my annual flu shot because I want to minimize my chance of getting sick and perhaps exposing my older patients to influenza.

Here’s what I’ll cover in this article:

The basics of influenza and vaccination against the flu
What we know about influenza and COVID-19
What to know about flu shots for older adults
What’s new and resources for the 2020-2021 flu season
Which influenza vaccination is probably best for most older adults
What to do if your older parent or relative is unwilling or unable to get vaccinated

6 Steps to Better High Blood Pressure Treatment for Older Adults

by Leslie Kernisan, MD MPH 157 Comments

Have you been concerned about high blood pressure (hypertension)? Or are you worried about an older relative having a stroke or heart attacks?

You’re not alone. After all, hypertension is the most common chronic condition among older adults, and medications for blood pressure (BP) are among the most commonly taken drugs in the US.

Even more important: poorly controlled hypertension is a major contributor to the most common causes of death and disability in older adults: strokes, heart attacks, and heart failure.

So it’s certainly sensible for older adults – and for those helping aging parents – to think about blood pressure.

And once you start thinking about high blood pressure, you’ll probably start to wonder.

Are the blood pressure medications you’re taking enough? Is your blood pressure at the “right” level or should you and your doctors work on changing things?

And what about that major research – the SPRINT trial — that made the news in 2015? (In this study, older adults randomized to aim for a lower BP did better than those who got “standard” BP treatment.)

These are excellent questions to ask, so I’d like to help you answer them.

Now, I can’t provide exact answers on the Internet. But what I can do is provide a sensible process that will help you successfully address these questions.

In this article, I’ll share with you the process that I use to:

Assess an older person’s blood pressure management plan, and
Determine whether we should attempt changes.

If you’re an older adult, you can use this approach to get started assessing your own BP management plan. This will help you to better work with your doctors on assessing and managing your blood pressure.

If you are helping an older relative manage health, you can follow these steps on behalf of your relative. [Read more…]

Q&A: What to Do About Unintentional Weight Loss

by Leslie Kernisan, MD MPH 107 Comments

Q: My 88-year-old father lives in his own home about 100 miles from us. He’s been living alone since my mother died five years ago. I thought he looked rather thin last time we saw him. I’m starting to feel worried about his nutrition. Should I be concerned? Would you recommend he start drinking a supplement such as Boost or Ensure?

A: This question comes up a lot for families. It is indeed very common for older adults to experience unintentional weight loss at some point in late-life.

The brief answer is that yes, you should be concerned. But I wouldn’t recommend you jump to purchasing Boost or Ensure.

Now, in most cases, some nutritional supplementation is in order. But before focusing on this, you should first get help figuring out why your father is losing weight.

For doctors, unintended weight loss is a major red flag when it comes to the health of an older person.

So in geriatrics, we usually recommend that an older person — or their caregivers — monitor weight regularly. This enables us to spot weight loss sooner rather than later.

Once we’ve spotted unintentional weight loss, the next step is to figure out what might be causing it. And then we’re in a better position to recommend a treatment plan, which might well include a nutritional supplement.

In this post, I’ll go over each of these steps in more detail.

Coronavirus Update & Suggestions (7.16.20 Edition)

by Leslie Kernisan, MD MPH 12 Comments

Like many of you, I continue to follow the coronavirus situation closely, for personal and professional reasons.

Given the dismaying surge in COVID cases over the past several weeks, this week I devoted part of my twice-monthly Helping Older Parents members call to this topic, and I have decided to share this part of the call below.

This video covers:

The coronavirus situation today
Are we better at preventing COVID?
Are we better at treating COVID?
Current COVID treatments available in the hospital
My take on hospitalization for frail older adults with COVID
Useful resources and my recommendations for this summer

The video is below, or get the audio-only through the podcast here.
(For those who have asked about transcripts: I wish I could but right now we are too short on funding; transcripts cost $1.25/minute to produce plus more time to format and finalize.)

Please stay as safe as you can, and take care!

How to Detect & Treat Vitamin B12 Deficiency in Older Adults

by Leslie Kernisan, MD MPH 79 Comments

Vitamin B12 Everyone knows that vitamins and nutrition are important for health, and many older adults take a multivitamin.

But did you know that even among older persons who do this, many still end up developing a serious deficiency in one particular vitamin?

It’s Vitamin B12.

If there’s one vitamin that I’d like all older adults and family caregivers to know more about, it would be vitamin B12.

(Second on my list would be vitamin D, but it’s much harder to develop low vitamin D levels if you take a daily supplement, as I explain in this post. Whereas vitamin B12 deficiency does develop in many older adults who are getting their recommended daily allowance.)

A deficiency in any vitamin can be catastrophic for health. But vitamin B12 deficiency stands out because a) it’s very common — experts have estimated that up to 20% of older adults may be low in this vitamin — and b) it’s often missed by doctors.

Geriatricians also like to pay attention to vitamin B12 because a deficiency can cause — or usually worsen — cognitive impairment or walking problems.

But if you know the symptoms and risk factors, you can help ensure that you get a vitamin B12 deficiency detected. Treatment is safe and effective, as long as you catch the problem before permanent damage occurs. Here’s what to know. [Read more…]
