Socioeconomic Disparities in Telemedicine Use and High-Need Nonuse Among Older Adults With Multimorbidity: A Cross-Sectional Analysis of NHANES August 2021–August 2023
This cross-sectional analysis of NHANES data reveals that while telemedicine use among older adults with multimorbidity is associated with both clinical need and socioeconomic resources, lower income significantly increases the likelihood of high-need nonuse, highlighting persistent disparities in access to remote care.

Imagine the healthcare system as a giant, bustling library where everyone needs to check out books (medical advice) to stay healthy. For older adults with multiple health issues—let's call them "super-complex readers"—this library has recently opened a new "Remote Reading Room." You can visit this room via video call or just a regular phone line, skipping the trip to the building entirely.
A team of researchers decided to peek inside the data from a massive national survey (NHANES) taken between August 2021 and August 2023 to see who was actually using this Remote Reading Room. They focused specifically on older folks (65+) who were juggling at least two different chronic health conditions.
The Big Reveal: Who is in the Remote Room?
The researchers found that out of all these older adults with multiple health issues, only about 39.7% had visited the Remote Reading Room in the past year. That means roughly 6 out of 10 people with complex health needs were still sticking to the old-fashioned way of visiting the library in person, or perhaps not visiting at all.
But here is the twist: The study suggests that getting into that Remote Reading Room isn't just about needing a doctor. It's heavily tied to your wallet and your education.
- The Education Factor: If you have a college degree or higher, you are nearly twice as likely (specifically, an odds ratio of 1.96) to use the remote room compared to someone who didn't finish high school.
- The Money Factor: The richer you are, the more likely you are to be there. People with higher family incomes were significantly more likely to use telemedicine than those with the lowest incomes.
- The Need Factor: Interestingly, having more health problems actually made people more likely to use the remote room. Every single extra chronic condition a person had bumped their chances of using telemedicine up by about 9%. Also, if someone had trouble moving around or doing daily tasks (a functional limitation), they were 1.5 times more likely to use the remote option.
The "High-Need" Mystery
The researchers then zoomed in on a specific group: the "High-Need" readers. These are the folks with at least three chronic conditions plus at least one functional limitation. These are the people who arguably need the Remote Reading Room the most because getting to the physical library is so hard for them.
In this high-need group, the researchers discovered a worrying gap. About 51.1% of these super-needy people did not use the Remote Reading Room at all. This is what the authors call "high-need nonuse."
When they looked closely at this group, the pattern was clear: Lower income was the main reason these high-need folks were missing out. People in this group with lower incomes were nearly twice as likely (an odds ratio of 1.92) to be stuck without remote care compared to their wealthier peers.
What the Paper Rules Out (and What It Doesn't Know)
It's important to know what this study doesn't say. The researchers explicitly state that they cannot prove that these people wanted to use telemedicine but couldn't.
- It's not a verdict on "bad care": The study does not say that not using telemedicine is a mistake. Some of these high-need people might simply prefer to see a doctor face-to-face, or their specific medical situation might require an in-person visit. The "nonuse" is just a flag that says, "Hey, this group might be missing out on remote options," not "This group is being ignored."
- It's not about depression: The researchers tried to see if feeling down (depressive symptoms) changed who used the remote room, but the data was too spotty to say for sure. So, they ruled out depression as a primary driver in their main findings.
- It's not about the future: The study doesn't predict what will happen next year or suggest specific fixes like "build more apps." It simply measures the current landscape.
How Sure Are They?
The researchers are very confident in the numbers they measured: they know exactly how many people used the service and how much education or income they had. They measured these relationships using statistical tools that account for the complex way the survey was designed.
However, they are careful to say that because this is a "snapshot" (a cross-sectional study), they can't prove that having more money caused someone to use telemedicine. They can only say the two things are linked. They also admit that because they didn't ask people why they didn't use the service, the "why" remains a bit of a mystery. It could be a lack of internet, a lack of a smartphone, or just a personal choice.
The Bottom Line
In simple terms, this study suggests that while telemedicine is a useful tool for older adults with many health problems, it's not reaching everyone equally. The "Remote Reading Room" is currently being used more by those with higher education and higher incomes. Even among the people who need remote care the most (those with three or more conditions and physical limitations), those with lower incomes are significantly less likely to be using it. The door is open, but for some, the path to the door is still blocked by economic barriers.
