Oral nutritional supplement use in relation to length of stay in heart failure patients at a regional medical center.

RATIONALE, AIMS, AND OBJECTIVES: Improving the nutritional status of hospitalized patients has been shown to reduce length of stay (LOS), hospital costs, readmission rates, complication rates, and mortality. Provision of nutrient-rich, liquid, oral nutrition supplements (ONS) is one approach to improve nutritional status. Little information is available on ONS use and LOS among heart failure patients.

METHODS

This study used a retrospective design to examine whether routine ONS use was associated with hospital LOS among 570 heart failure inpatients (89 ONS = yes; 481 ONS = no) at a regional medical center, adjusting for significant personal, locational, and time variables using multiple logistic regression analysis.

RESULTS

Oral nutrition supplement use was associated with high LOS in this sample (odds ratio = 2.43). High LOS was also associated with higher Charlson comorbidity index values, discharge destination, hospital room location, and dietitian consults.

CONCLUSIONS

These results show that ONS orders alone are not adequate to reduce LOS among heart failure patients. Continued research is needed on ways to improve care to reduce LOS among hospitalized patients.
