BackgroundMalnutrition is highly prevalent in hospitalized patients and results in a worsened clinical course as well as an increased length of stay, mortality, and costs. Therefore, simple nutrition screening systems, such as CIPA (control of food intake, protein, anthropometry), may be implemented to facilitate the patient’s recovery process. The aim of this study is to evaluate the effectiveness and cost-effectiveness of implementing such screening tool in a tertiary hospital, consistent with the lack of similar, published studies on any hospital nutrition screening system.MethodsThe present study is carried out as an open, controlled, randomized study on patients that were admitted to the Internal Medicine and the General and Digestive Surgery ward; the patients were randomized to either a control or an intervention group (n = 824, thereof 412 patients in each of the two study arms). The control group underwent usual inpatient clinical care, while the intervention group was evaluated with the CIPA screening tool for early detection of malnutrition and treated accordingly.CIPA nutrition screening was performed upon hospital admission and classified positive when at least one of the following parameters was met: 72 h food intake control < 50%, serum albumin < 3 g/dL, body mass index < 18.5 kg/m2 (or mid-upper arm circumference ≤ 22.5 cm). In this case, the doctor decided on whether or not providing nutrition support.The following variables will be evaluated: hospital length of stay (primary endpoint), mortality, 3-month readmission, and in-hospital complications. Likewise, the quality of life questionnaires EQ-5D-5 L are being collected for all patients at hospital admission, discharge, and 3 months post-discharge. Analysis of cost-effectiveness will be performed by measuring effectiveness in terms of quality-adjusted life years (QALYs). The cost per patient will be established by identifying health care resource utilization; cost-effectiveness will be determined through the incremental cost-effectiveness ratio (ICER). We will calculate the incremental cost per QALY gained with respect to the intervention.DiscussionThis ongoing trial aims to evaluate the cost-effectiveness of implementing the malnutrition screening tool CIPA in a tertiary hospital.Trial registrationClinical Trial.gov (NCT02721706).First receivevd: March 1, 2016Last updated: April 8, 2017Last verified: April 2017

Malnutrition is prevalent in surgical patients and leads to comorbidities and a poorer postoperative course. There are no studies that compare the clinical outcomes of implementing a nutrition screening tool in surgical patients with standard clinical practice. An open, non-randomized, controlled study was conducted in general and digestive surgical hospitalized patients, who were either assigned to standard clinical care or to nutrition screening using the Control of Food Intake, Protein, and Anthropometry (CIPA) tool and an associated treatment protocol (n = 210 and 202, respectively). Length of stay, mortality, readmissions, in-hospital complications, transfers to critical care units, and reinterventions were evaluated. Patients in the CIPA group had a higher Charlson index on admission and underwent more oncological and hepatobiliary-pancreatic surgeries. Although not significant, a shorter mean length of stay was observed in the CIPA group (−1.48 days; p < 0.246). There were also fewer cases of exitus (seven vs. one) and fewer transfers to critical care units in this group (p = 0.068 for both). No differences were detected in other clinical variables. In conclusion, patients subjected to CIPA nutrition screening and treatment showed better clinical outcomes than those receiving usual clinical care. The results were not statistically significant, possibly due to the heterogeneity across patient groups.
