We assessed the prevalence, methods for recognition and clinical management of malnutrition in acute admissions in a large academic inner-city hospital. Of a total of 337 patients, it was possible to measure both height and weight in 219 patients (65% of admissions). As an alternative for bed-bound patients, mid-upper arm circumference was not very reliable in predicting BMI (sensitivity 98%; specificity 65%), and waist circumference even less so. Of these, 13% were malnourished (body mass index BMI 3 kg in the last 3 months). Six patients (31% of those with BMI <18.5 kg/m(2)) and one with BMI 18.5-20 kg/m(2) were recognized as suffering from malnutrition and referred to the dietitian. Review of case records could not establish if the diagnosis was missed in the remainder, or if a conscious decision was taken not to manage malnutrition actively. Malnutrition in acute hospital admissions goes apparently unrecognized and unmanaged in 70% of cases. Since there are serious consequences, and effective simple treatment is readily available, increased awareness is required, with routine assessment of nutritional status in all patients.
