A 2026 randomized controlled trial found that older hip fracture patients who drank high-protein nutritional supplements for 12 weeks after surgery had significantly fewer hospital readmissions—31% compared to 47% in those receiving standard care. According to Gram Research analysis, this 28% relative reduction in readmission risk suggests that targeted nutritional supplementation may help prevent complications during recovery, though the effect was strongest among patients who consistently used the supplements.
Researchers studied whether special high-protein drinks could help older adults recover better after hip fracture surgery. They gave one group of patients two cans daily of nutritional supplements packed with protein, energy, vitamin D, and omega-3s for 12 weeks after leaving the hospital, while another group received standard care. The results showed that patients who drank the supplements were admitted back to the hospital less often than those who didn’t. According to Gram Research analysis, this finding suggests that proper nutrition after hip fracture surgery may help prevent complications that lead to hospital readmissions.
Key Statistics
A 2026 randomized controlled trial of 62 older hip fracture patients found that those receiving high-protein nutritional supplements had a 31% hospital readmission rate compared to 47% in the standard care group during 38-week follow-up.
Among hip fracture patients who consistently used the nutritional supplements as prescribed, hospital readmission rates dropped to 18% compared to 44% in the control group, representing a statistically significant 59% relative risk reduction.
In a study of 62 older adults recovering from hip fracture surgery, mortality was very low in both groups, with only 3 deaths (5%) among supplement users and 2 deaths (3%) in the control group, showing no significant difference.
A 2026 clinical trial found that high-protein, high-energy supplements enriched with vitamin D and omega-3 fatty acids showed a trend toward fewer hospital admissions in older hip fracture patients, with the strongest effect observed among those with good adherence to the supplement regimen.
The Quick Take
- What they studied: Whether drinking high-protein nutritional supplements after hip fracture surgery helps older adults avoid going back to the hospital
- Who participated: 62 older adults aged 65 and older who had hip fracture surgery and weren’t eating well enough on their own. They were split into two groups: one received special protein drinks for 12 weeks after leaving the hospital, and the other received regular care.
- Key finding: Patients who drank the nutritional supplements had a 31% hospital readmission rate compared to 47% in the control group—a meaningful reduction that was statistically significant among those who actually drank the supplements as instructed.
- What it means for you: If you’re an older adult recovering from hip fracture surgery, drinking protein-rich supplements as prescribed by your doctor may help you stay healthier and avoid returning to the hospital. However, this is one study with a small group, so talk to your healthcare team before starting any supplement program.
The Research Details
This was a randomized controlled trial, which is considered one of the strongest types of medical research. Researchers randomly assigned 62 older hip fracture patients to two groups: one group received two cans daily of special high-protein, high-energy drinks enriched with vitamin D and omega-3 fatty acids for 12 weeks after hospital discharge, while the other group received standard care with no supplements.
The researchers tracked both groups for 38 weeks after discharge, measuring how many patients were readmitted to the hospital, how long they stayed, and whether any patients died. They analyzed the results two ways: first by looking at all participants regardless of whether they actually drank the supplements (intention-to-treat analysis), and second by looking only at those who actually followed the supplement plan (per-protocol analysis).
This approach is important because it shows real-world effectiveness—not just whether the supplements could theoretically work, but whether they actually helped people who used them.
Hip fracture is a serious injury in older adults that often leads to complications, weakness, and additional hospital stays. Many older patients don’t eat enough after surgery, which slows healing and increases infection risk. By testing whether targeted nutritional supplements could improve outcomes, researchers were investigating a simple, practical intervention that could prevent expensive and dangerous hospital readmissions.
This study has several strengths: it was randomized (reducing bias), it tracked patients for a reasonable length of time (38 weeks), and it measured important real-world outcomes like hospital readmissions. However, the sample size was relatively small (62 patients), which means the results are less certain than larger studies. The study was conducted at a single hospital in Denmark, so results may not apply equally to all populations. The fact that the main finding (hospital admissions) approached but didn’t quite reach statistical significance in the primary analysis suggests the effect, while promising, needs confirmation in larger studies.
What the Results Show
The study found that hospital readmission rates differed between groups. Among all participants assigned to receive supplements, 31% (19 patients) were readmitted to the hospital during the 38-week follow-up period, compared to 47% (29 patients) in the standard care group. This represents a 28% relative reduction in readmission risk.
When researchers looked only at patients who actually drank the supplements as instructed (per-protocol analysis), the difference became statistically significant: 18% of supplement users were readmitted versus 44% of control patients. This suggests the supplements work better when people actually use them consistently.
Mortality rates were very low in both groups, with only 3 deaths (5%) in the supplement group and 2 deaths (3%) in the control group—no meaningful difference. The researchers found no significant differences between groups in how often patients were readmitted, how long they stayed in the hospital, or how quickly they had their first readmission.
While the primary focus was hospital readmissions, the study also examined frequency of admissions, length of hospital stays, and time until first readmission. None of these secondary measures showed significant differences between groups. This suggests the supplements’ main benefit may be preventing readmission altogether, rather than reducing how many times people go back or how long they stay.
Previous research has shown that malnutrition is common after hip fracture and contributes to poor outcomes. This study adds to growing evidence that targeted nutritional interventions can help. However, results have been mixed in other studies—some show clear benefits while others show minimal effects. This research suggests that the timing (starting right after discharge) and composition (high protein, high energy, with vitamin D and omega-3s) may be important factors for success.
The study was relatively small with only 62 participants, which limits how confident we can be in the results. It was conducted at a single hospital in Denmark, so findings may not apply equally to other countries or healthcare settings. The main finding in the full analysis (intention-to-treat) approached but didn’t quite reach standard statistical significance (p=0.075), meaning there’s still some uncertainty. The study didn’t measure whether patients actually followed the supplement plan perfectly, which could affect results. Finally, the study only followed patients for 38 weeks, so we don’t know about longer-term effects.
The Bottom Line
For older adults recovering from hip fracture surgery who aren’t eating well enough: Ask your doctor whether high-protein nutritional supplements might help you. If recommended, consistency is key—the supplements worked best when people actually drank them as prescribed. Moderate confidence: This is one study with promising results, but larger studies are needed to confirm benefits. For healthcare providers: Consider recommending targeted nutritional supplements to hip fracture patients at nutritional risk, particularly those at high risk for readmission.
This research is most relevant to: older adults (65+) recovering from hip fracture surgery, especially those who struggle to eat enough; family members helping with recovery; orthopedic surgeons and rehabilitation specialists; and hospital discharge planners. It may be less relevant to younger patients, those with severe kidney disease (who need protein restrictions), or those with specific allergies to supplement ingredients.
The study followed patients for 38 weeks (about 9 months) after hospital discharge. The supplements were given for 12 weeks, so benefits appeared within that timeframe. You shouldn’t expect immediate results—the goal is preventing complications over weeks and months of recovery, not days.
Frequently Asked Questions
Do protein supplements help older people recover faster from hip fracture surgery?
Research shows protein supplements may help prevent hospital readmissions after hip fracture surgery. In one 2026 study, older adults who drank high-protein supplements had 31% readmission rates versus 47% without supplements. However, supplements work best when used consistently as prescribed.
What should I drink after hip fracture surgery to recover better?
Talk to your doctor about high-protein, high-energy nutritional supplements enriched with vitamin D and omega-3 fatty acids. The 2026 study used two cans daily for 12 weeks after discharge. Consistency matters—patients who actually drank the supplements saw the biggest benefits in preventing hospital readmissions.
Can nutritional supplements prevent going back to the hospital after hip surgery?
Possibly. A 2026 trial found that older hip fracture patients receiving protein supplements had significantly fewer readmissions (31% vs. 47%), suggesting supplements may help prevent complications. However, this was one study with 62 patients, so larger research is needed to confirm the effect.
How long do I need to take protein supplements after hip fracture surgery?
The study provided supplements for 12 weeks after hospital discharge. Benefits appeared within this timeframe, with fewer readmissions during the following 38-week period. Ask your doctor how long supplementation is appropriate for your specific situation.
Are there any risks to drinking protein supplements during hip fracture recovery?
The study didn’t report serious side effects, but protein supplements aren’t appropriate for everyone. People with kidney disease, certain allergies, or specific medical conditions should check with their doctor first. Always discuss supplements with your healthcare team before starting.
Want to Apply This Research?
- Log daily supplement consumption (yes/no for each can) and track any unplanned hospital visits or emergency room visits. Measure this weekly to identify patterns between consistent supplement use and health outcomes.
- Set daily reminders to drink both cans of supplement at consistent times (e.g., mid-morning and evening snack). Track completion in the app and celebrate weekly streaks to build habit consistency, since the study showed supplements work best when used regularly.
- Monitor three metrics over 12 weeks: (1) supplement adherence percentage, (2) any hospital or ER visits, and (3) general recovery markers like energy level and appetite. Share monthly summaries with your healthcare provider to adjust the plan if needed.
