A study suggests that oral nutritional supplementation (ONS) among hospitalized older adults with COPD appears to reduce length of stay (LOS), hospitalization costs, and readmission risks when compared with no ONS:
| ONS Hospitalization | Non-ONS Hospitalization | |
| LOS | 6.9 days | 8.8 days |
| Hospitalization costs | $10,953 | $12,523 |
| Probability of 30-day readmission | 0.29 | 0.34 |
