Comparison of CIPA With the GLIM Criteria of Malnutrition and Prevalence of Sarcopenia in Inpatients

Background: malnutrition is a poor prognostic factor in inpatients. Its early detection, together to nutritional intervention, can improve clinical evolution. It is important to carry out nutritional screening, however, there is no gold standard, and CIPA (Control of Intakes, Proteins and Anthropometry) has been implemented in our setting. The GLIM criteria (Global Leadership Initiative on Malnutrition) aim to provide a global consensus that allows common criteria for malnutrition diagnosis. The objective of this study is to evaluate the diagnostic quality of the CIPA screening vs the GLIM criteria for malnutrition as well as to establish the prevalence of sarcopenia.

Methods: cross-sectional single-center study comparing the diagnostic quality of CIPA in the diagnosis of malnutrition or risk of presenting it in inpatients vs GLIM. Adults of both sexes with a hospital stay of more than three days and attached to one of the following departments will be included: general surgery, internal medicine, vascular surgery, digestive system, hematology, nephrology, pulmonology, oncology, neurology, traumatology. The diagnostic evaluation of malnutrition and functionality will be carried out after three days of hospital stay, once the CIPA screening has been carried out. The participation of the patients in the study will consist of performing the CIPA malnutrition screening to which the GLIM test will be added. For the CIPA test, the BMI (body mass index), albumin levels and percentage of decreased intake will be taken. For the GLIM test, phenotypic criteria such as non-voluntary weight loss and reduction in muscle mass will also be studied together with etiological criteria to which, in addition to those referred to for the CIPA test, the presence of inflammation will be added. The study consists of a first cross-sectional part that will be completed once the data of the 490 subjects selected through probabilistic sampling has been collected. The second part of the study will consist of the prospective follow-up of the patients and the variables will be analyzed with prognostic criteria.

Discussion: this study will evaluate the diagnostic quality of CIPA vs the GLIM criteria for malnutrition and will establish the prevalence of sarcopenia in inpatients.
