UpToDate engagement report
@UpToDate - 141K followers on X
Measured over 58 original posts from a 30-day window, last computed on September 27, 2026.
Engagement
A typical post picks up 1 interaction against 141K followers, an engagement rate of 0.001%. Measured over 58 original posts, its engagement rate beats 3% of 20,444 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 1.7K times each, and 0.059% of those impressions turn into an interaction. That is about 1.20% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 14:00 UTC, and Wednesday is the busiest day of the week. Of the 58 posts sampled, 100% carry an image or video and 78% link out. The account's strongest tracked post pulled 8 interactions, about 8.0x its own typical post. Recurring topics include #uptodate, #clinicalupdates, #drugnews.

Compared with accounts its own size
UpToDate's engagement rate beats 3% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 8 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 4% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.
Where this sits in the catalog
At 0.001%, UpToDate sits below the 10th percentile of the 205,582 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.024%.

Posting timing
This account posts most often around 14:00 UTC, and Wednesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 100% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 78% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 100% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 78% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 417 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

🧠It's Clinical Challenge time! This week's scenario comes from our Pulmonary specialty. A 58-year-old man with type 2 diabetes is seen for a nonproductive cough that has persisted for 10 weeks. He denies wheeze, dyspnea, fever, and postnasal drip. Chest radiograph is normal. He is not taking an angiotensin-converting enzyme (ACE) inhibitor. Three months ago, he started a glucagon-like peptide 1 receptor agonist (GLP-1 RA) as add-on therapy. He has no prior diagnosis of gastroesophageal reflux disease (GERD). Which statement best reflects the evidence and a key clinical implication regarding this medication and his cough? A. GLP-1 RAs have been shown prospectively to reduce chronic cough, so the medication is unlikely to be relevant. B. GLP-1 RAs may contribute to chronic cough in a small percentage of users, and the relative increase appears stronger in patients without a GERD diagnosis. C. GLP-1 RAs cause chronic cough primarily through bronchoconstriction and should be managed like asthma. D. A positive association between GLP-1 RAs and chronic cough has been excluded by large database studies. What's your answer? Reply with your response 👇

🧠It's Clinical Challenge time! Today's question comes from our Anesthesiology specialty A 62-year-old man with type 2 diabetes takes a weekly glucagon-like peptide 1 receptor agonist (GLP1-RA). He is scheduled for elective surgery under general anesthesia. He has severe pulmonary compromise, so aspiration would have high clinical consequences. He followed standard preoperative fasting instructions. On the morning of surgery, he reports nausea and abdominal bloating. Which is the most appropriate next step? A. Proceed as usual because standard fasting reliably excludes residual gastric contents in GLP-1 RA users. B. Proceed as usual because gastrointestinal (GI) symptoms correlate well with normal gastric emptying. C. Perform point-of-care gastric ultrasound to assess gastric volume, then discuss risks and benefits of proceeding versus rescheduling based on findings and symptoms. D. Cancel the procedure solely because the patient is taking a GLP-1 RA, regardless of symptoms or aspiration risk. Reply with your answer 👇

Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.

Reading these numbers
A typical post picks up 1 interaction against 141K followers, an engagement rate of 0.001%. Measured over 58 original posts, its engagement rate beats 3% of 20,444 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 1.7K times each, and 0.059% of those impressions turn into an interaction. That is about 1.20% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 14:00 UTC, and Wednesday is the busiest day of the week. Of the 58 posts sampled, 100% carry an image or video and 78% link out. The account's strongest tracked post pulled 8 interactions, about 8.0x its own typical post. Recurring topics include #uptodate, #clinicalupdates, #drugnews.
- What is UpToDate's engagement rate on X?
- UpToDate (@UpToDate) has an engagement rate of 0.001%, based on the median interactions across 58 original posts from the last 30 days against 140,706 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.001%, UpToDate sits below the 10th percentile of the 205,582 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @UpToDate have real engagement?
- Its engagement rate beats 3% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the bottom 10% for its size group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @UpToDate post?
- Most posts go out around 14:00 UTC, and Wednesday is its busiest day, at roughly 1.93 posts per day across the measured window.
