摘要: BACKGROUND COPD is a leading cause of death and disability in the United States. Patients with are at high risk nutritional deficiency, which associated declines respiratory function, lean body mass strength, immune function. Although oral supplementation (ONS) has been improvements some these domains, impact hospital ONS on readmission risk, length stay (LOS), cost among hospitalized patients unknown. METHODS Using Premier Research Database, we first identified Medicare aged ≥ 65 years primary diagnosis COPD. We then hospitalizations was provided, used propensity-score matching to compare LOS, hospitalization cost, 30-day rates one-to-one matched sample non-ONS hospitalizations. To further address selection bias prescribed ONS, also instrumental variables analysis study association outcomes. Model covariates included patient provider characteristics time trend. RESULTS Out 10,322 368,097 hospitalizations, created (N = 14,326). In unadjusted comparisons sample, use longer LOS (8.7 days vs 6.9 days, P .0116). However, analysis, 1.9-day (21.5%) decrease from 8.8 ( CONCLUSIONS may be reduced
