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.
长期住院患者及外科病房患者存在营养不良的情况已有充分记录。本研究旨在确定因急性内科疾病入院的老年患者中该问题的严重程度，并评估营养状况与住院病程之间的关系。69例患者在入院时及住院期间定期接受营养评估，并记录败血症发作情况。使用体重指数（BMI，22%）和校正臂肌面积（CAMA，26%）确定严重营养不良患者。严重营养不良组败血症发作的频率明显更高（p < 0.04）。该组的中位住院时间为16天（范围2 - 113天）：在此期间，除实际肌肉周长（AMC）外，营养状况指标无显著变化，AMC在入院和出院时的测量值显示有统计学意义的下降（p < 0.0003）。本研究表明，严重营养不良在老年内科住院患者中很常见，且与败血症风险增加有关。住院期间可能会出现额外的营养消耗，除非进行人体测量，否则不易识别。
