Nutritional status of patients in hospitals in Poland. I. Screening of adult patients

The aim of the study was a screening assessment of the nutritional status of patients admitted to hospitals and discharged from hospitals. The study was carried out in 4 university hospitals, 4 woivodeship hospitals and 4 district hospitals. In randomly selected 3310 patients (every 10th patient admitted to hospital) anthropometric parameters were assessed: body height, body mass, body mass index (BMI), waist-hip ratio (WHR), arm circumference, blood morphological and biochemical parameters were determined (erythrocyte, white blood cell and lymphocyte count in blood, albumin and haemoglobin concentration in serum). The mean values of the assessed parameters in the whole studied population of patients admitted to various types of hospitals were not different from the normative values for adults, however, a gradual decrease of the values of certain parameters in the over 70 years age group was observed. Although, the mean values of the studied parameters of the nutritional status were within the accepted normal range, 10.43% of the studied patients had BMI below 20 kg/m2, and 20.7% of the patients the serum albumin level was below 3.5 g/dl on admission, which could suggest protein-energy malnutrition. In a yet higher proportion of patients (21%) lymphocyte count was below 1500/mm3. During hospital stay tendency became even more pronounced. On discharge from hospital the proportion of patients with BMI below 20 kg/m2 rose to 11.21%, and with serum albumin level below 3.5 g/dl rose to 28.6%. Only the proportion of patients with low lymphocyte count remained unchanged during hospital stay and was 21.1% on discharge. In the studied population 42.29% of the patients reported receiving of additional food beyond hospital diet.
