3-Month Oral Nutritional Supplementation Adherence Impacts Positively on Survival in Malnourished Older Patients Following Hip Fracture: A Real-Life Study

Why It Matters

Ensuring ONS adherence can halve mortality risk among malnourished elderly hip‑fracture patients, offering a cost‑effective lever for hospitals and fracture liaison services to improve outcomes.

Key Takeaways

• 3‑month ONS adherence cuts one‑year mortality risk.
• Non‑adherent malnourished patients face ~3.7× higher death risk.
• Adherent malnourished patients' survival similar to well‑nourished.
• Pharmacy dispensing used as adherence proxy in real‑world cohort.
• Multidisciplinary discharge planning needed to ensure ONS compliance.

Pulse Analysis

Hip fractures in older adults carry a steep mortality toll, and malnutrition compounds this risk by impairing recovery and increasing complications. As populations age, the prevalence of fragility fractures rises, prompting health systems to adopt fracture liaison services that integrate medical, surgical, and rehabilitative care. Nutrition, however, remains a pivotal yet often under‑addressed component; inadequate protein and energy intake can accelerate sarcopenia, delay wound healing, and elevate infection rates, all of which contribute to poorer survival outcomes.

The Frontiers in Nutrition study followed 300 patients for one year, using pharmacy dispensing records to define ONS adherence as three months of continuous retrieval. Compared with non‑adherent malnourished peers, adherent patients experienced a 63% reduction in mortality risk (hazard ratio 0.37 after landmark analysis). Non‑adherent individuals faced a 3.7‑fold higher hazard, underscoring that duration of supplementation—not merely prescription—drives the survival advantage. These findings align with earlier trials showing functional gains from early ONS but extend the evidence to hard‑endpoint mortality.

For clinicians and administrators, the implication is clear: embedding adherence‑focused nutrition protocols into discharge planning can save lives. Strategies may include prescribing low‑volume, high‑protein formulas, arranging home‑delivery services, and assigning dietitian or nursing staff to monitor pharmacy pick‑ups. Integrating ONS metrics into electronic health records enables real‑time alerts for missed refills, while multidisciplinary teams can address barriers such as taste fatigue or cognitive impairment. Future randomized studies should refine optimal supplement composition, duration, and delivery models to cement nutrition as a cornerstone of hip‑fracture care.
