Patients' nutritional status is not recorded
EDITOR,--C J Todd and colleagues found considerable differences among hospitals in mortality, length of stay in hospital, and the development of pressure sores in patients with hip fracture.1 Although the patients from the eight hospitals are said to have been well matched, no information is provided on the patients' nutritional status on arrival or on their subsequent nutritional care.
Simple anthropometric variables, such as weight in relation to height, the circumference of the midupper arm, and triceps skin fold thickness, have been used to assess nutritional status in patients with hip fracture and have proved to be predictors of mortality and length of stay in hospital.2 3 Malnourished patients receiving supplemental oral or enteral nutrition have shown fewer complications, a shorter stay in hospital and lower mortality.2 3 4 5 For example, patients receiving an oral supplement of 250 ml daily in one study had a median hospital stay of 40 days, compared with 24 days in a group not given the supplement.4
Clearly, differences in nutritional management can be important not only for outcome but also for hospital costs.
