International study on the prevalence of malnutrition in centralized care for colorectal cancer patients

Abstract

Abstract Objectives Patients with different diseases may show signs of malnutrition both before and during the hospital stay. The presence of malnutrition may impact the recovery and length of stay and consequently the costs. Early identification of malnutrition is thus a critical factor. The objective of this multicenter study is to determine the prevalence of malnutrition in colorectal cancer centers. Another objective is to investigate possible consequences, such as complications or length of stay. In addition, the study aims to demonstrate the relevance of nutrition management in colorectal cancer centers. At the same time, relevant requirements clearly demanded by the Certification Commission for Certified Colorectal Cancer Centers are met through implementation of the study. Methods Between 2019 and 2021, patients in colorectal cancer centers were examined in the preoperative phase. In addition to questions about patients’ state of health and nutrition, the validated screening forms—Subjective Global Assessment (SGA) and Nutritional Risk Screening Tool 2002 (NRS 2002)—were used to assess malnutrition. The data were processed by univariate analysis. Results In total, data records of 3,102 patients were evaluated. The mean age of the participants was 68.5 ± 11.9 years, and their average body mass index (BMI) was 26.8 ± 5.3 kg/m2. The SGA questionnaire indicated that 23 % of the participants suffered from malnutrition and 38 % were at risk of malnutrition (NRS≥3). Malnutrition was found more frequently in patients with colorectal carcinomas than in patients with rectal carcinomas (53.1 vs. 32.1 %). The length of stay in hospital and the rate of complications were significantly higher when malnutrition was identified. Conclusions Approximately one in three to four patients with a colorectal carcinoma has an increased risk of malnutrition. The two screening methods calculated a different prevalence (23 and 38 %). Any malnutrition that is present demonstrably has a significant impact both on the rate of complications and the length of stay and may therefore have a decisive influence on the costs. The results of this multicenter study underscore the need for systematic screening for malnutrition and at the same time should increase clinics awareness of the importance of establishing a nutrition management policy.
