Baseline Nutritional Status and Rehabilitation Progress in Individuals Requiring Inpatient Rehabilitation: A Retrospective Cohort Study.
Hideki Arai, Syuya Okada, Tatsuyuki Fukuoka and 3 others
PMID 39372250WHAT IT FOUND
73% of the 409 patients had malnutrition, but baseline nutritional status was not related to medical events or rehabilitation progress.
Therapists should not expect poorer recovery or more medical events solely from admission malnutrition.
Key findings
0173% of the 409 patients had malnutrition at admission.
02Medical events at 150 days occurred in 22.1% of the normal nutrition group, 21.3% of the mild malnutrition group, and 19.9% of the moderate or severe malnutrition group.
03Functional Independence Measure motor and cognitive efficiency scores did not differ among the nutritional groups.

What it does not show
This was a single-center retrospective study of medical records at one Japanese rehabilitation hospital, so results may not apply to other settings or patients. Nutritional status was measured only at admission. Changes during hospitalization and medications were not assessed. Medical events were defined by the attending physician as death or acute illness requiring transfer. This definition was less robust. Rehabilitation was combined physical, occupational, and speech therapy, individualized by disability, so the contribution of any single component cannot be separated. Follow-up was short, with median 73 days, which may be inadequate to detect nutrition-related effects on medical events or cognitive function. Some baseline data were missing and were not imputed. The study did not assess rehabilitation protocols or factors other than nutrition that could affect outcomes.
The easy way to misread this
Do not conclude that malnutrition is harmless in inpatient rehabilitation. This was a single-center retrospective cohort, and rehabilitation included physical, occupational, and speech therapy together, so the study cannot show that nutritional status has no effect on rehabilitation progress or medical events.
