Shoulder Arthroplasty Studies

Targeted Nutritional Supplementation (TNS) has been successfully used in multiple clinical settings. Enhanced outcomes are seen in orthopedic studies demonstrating improved post-op clinical outcomes with nutritional supplementation.

Nutritional status is a strong predictive factor in shoulder arthroplasty outcomes.

  • Poor nutritional status in shoulder arthroplasty significantly increases risk for:

    *Blood transfusion

    *Longer hospital (LOS)

    *Death within 30 days of surgery

  • Malnutrition in shoulder arthroplasty significantly increases:

    *LENGTH OF STAY

    Primary TSA 26.8% vs. 13.6%

    Revision TSA 30.8% vs. 6.7%

    *DISCHARGE TO REHAB/SNF

    Primary TSA 18.3% vs. 10.3% 

    Revision TSA 26.9% vs. 4.4%

  • Malnutrition increases length of stay and 90-day cost of care after shoulder arthroplasty

    *Cost : 90-day charges + $6971

    *LOS: + 3.7 days

    *Risk of 90-day readmission: 3.0x fold
