To apply nutritional risk screening 2002 (NRS2002) to analyze the nutritional risk of abdominal wall infection patients with type 2 diabetes mellitus in the western campus of Beijing Chaoyang hospital and to evaluate the nutritional status of hospitalized patients with abdominal wall infection combined with type 2 diabetes, and to know whether there is any difference in nutritional risk in age.

A total of 135 patients with abdominal wall infection and type 2 diabetes mellitus in the western campus of Beijing Chaoyang hospital were collected by NRS2002. The general information was collected by continuous fixed-point sampling. Nutritional risk screening was carried out within 2 days after admission, the nutritional status of patients during hospitalization was analyzed, and the necessity of nutritional support was evaluated. There were 83 males and 52 females, aged from 41 to 82 (65.0±9.2) years. NRS2002 score is the sum of nutritional status score, disease severity score and age score (<70 years old is 0 and ≥70 years old is 1).

All 135 inpatients completed nutritional risk screening NRS2002, including 49 cases (36.8%) with nutritional risk (NRS2002 score ≥3 points) and 86 cases (63.8%) without nutritional risk (NRS2002 score <3 points). The nutritional intervention rates of patients with nutritional risk and patients without nutritional risk were 65% and 19%, respectively. The nutritional risk varies with age after 70 years old. The incidence of nutritional risk in patients aged ≥70 years old was higher than that in patients aged <70 years old.

There is a high incidence of malnutrition and nutritional risk in hospitalized patients with abdominal wall infection and type 2 diabetes. The NRS2002 scale is simple and easy to perform. It can effectively screen the nutritional status of abdominal wall infection patients with type 2 diabetes.
