The nutritional status and clinical course of acute admissions to a geriatric unit.

Undernutrition of long-stay hospital patients and those in surgical units is well documented. This study was designed to determine the extent of the problem in elderly people admitted to hospital with acute medical problems and to assess the relationship between nutritional status and course of hospital stay. Sixty-nine patients underwent a nutritional assessment on admission and at intervals throughout their hospital stay and episodes of sepsis were documented. Severely malnourished patients were identified using body mass index, BMI (22%) and corrected arm muscle area, CAMA (26%). Episodes of sepsis occurred significantly more often in the severely undernourished group (p < 0.04). The median length of stay of the group was 16 days (range 2-113): during this time there was no significant change in markers of nutritional status apart from actual muscle circumference (AMC), which showed a reduction in measurement between admission and discharge which was statistically significant (p < 0.0003). This study indicated that severe malnutrition is common in elderly medical admissions, and that it is associated with an increased risk of sepsis. Additional nutritional depletion may occur during hospital stay, and is not easily recognized unless anthropometry is undertaken.
