Impact of Oral Nutritional Supplementation at Hospital Discharge on Healthcare Costs in Older Adults: A Retrospective Analysis of Japanese Claims Data.

ABSTRACT:

Aim

Malnutrition is a common and costly challenge among hospitalized patients and those requiring postdischarge care. Oral nutritional supplements (ONSs) are a low-cost intervention for undernourished individuals. This study used the Kokuho Database (KDB) to examine the health economic impact of prescribing ONSs at discharge for hospitalized older adults.

Methods

This retrospective study included patients aged 75 years and older who were discharged from hospitals in Saitama Prefecture, as recorded in the KDB, from April 2017 to March 2022. Patients prescribed ONSs at discharge were classified as the ONS-at-discharge (ONSd) group, and those not prescribed were classified as the no-ONS-at-discharge (non-ONSd) group. Healthcare costs over 360 days postdischarge were compared us
