The First Experience of Creating a Mobile Application for Diagnosis and Correction of Nutritional Deficiency in Cancer Patients

Nutritional deficiency is a problem that occurs in 30 % to 80 % of cancer patients, but is often undiagnosed. In the era of digitalization, it is important to create programs aimed at increasing the availability of medical care. The purpose of the study was to create a mobile application for the diagnosis and correction of nutritional deficiency in cancer patients. Material and methods. A prospective study was conducted among cancer patients. Group 1 - cancer patients with nutritional deficiency (n=105), group 2 - without nutritional deficiency (n=96). Both groups were matched for age, gender, cancer diagnosis and concomitant pathology (p>0.05). The main phases of the study were: identification of significant markers associated with nutritional deficiency in cancer patients - complete blood count and biochemical analysis, anthropometric parameters and results of the functional tests; analysis of the capabilities of the mobile application; development of the application; validation of the created product.
