How does nutritional state change during a subacute admission? Findings and implications for practice.

Area of Science:

• Gerontology
• Clinical Nutrition
• Rehabilitation Medicine

Background:

• Nutritional status is a key determinant of patient outcomes in clinical and functional recovery.
• Subacute care settings present unique challenges and opportunities for nutritional intervention.
• Understanding nutritional status changes is crucial for optimizing patient care pathways.

Purpose of the Study:

• To identify changes in nutritional status among patients admitted to subacute care.
• To determine participant characteristics associated with nutritional status changes.
• To evaluate the effectiveness of subacute care on patient nutrition.

Main Methods:

• A longitudinal study design involving 248 consecutive patients over a 3-month period.
• Utilized the full Mini Nutritional Assessment (full MNA) for nutritional classification at admission and discharge.
• Secondary outcomes included weight, mid-arm/calf circumference, hand grip strength, and fat-free mass via bioelectrical impedance analysis.

Main Results:

• On admission, 29.1% of patients were classified as malnourished.
• Nutritional classification remained stable for 62.0%, declined for 10.3%, and improved for 27.7% of patients.
• Impaired cognition and higher initial full MNA scores were associated with reduced likelihood of nutritional improvement; fat-free mass declined significantly (-1.1 kg).

Conclusions:

• Multidisciplinary care in subacute settings generally supports patient nutritional status.
• Patients with cognitive impairments or at risk of malnutrition may require more intensive or tailored nutritional support.
• Further research into personalized nutritional strategies for vulnerable subacute care populations is warranted.
