Evaluation of a Novel Artificial Intelligence System to Monitor and Assess Energy and Macronutrient Intake in Hospitalised Older Patients

“…In this preliminary study, the weight of the dishes and the meal components was not measured before and after consumption and, thus, the ground truth (GT) could not be obtained by this procedure. For this reason, the mean of the estimations of the two dietitians and the trained medical student for the consumed percentage of each meal component was used as a reference and defined as visual estimations (reference) due to a high correlation with weighing [12,[17][18][19][20][21]. In order to calculate the energy and macronutrient intake of the food consumed by the patients, the nutritional information of the individual menus was retrieved from the kitchen database (SANALOGIC Solutions GmbH [26]).…”

“…The current gold standard for the estimation of consumed food is the weighing of patient's meals before and after consumption and the calculation of energy and nutrient intake based on weight difference [12]. Since weighing individual meals is very demanding, different studies have used visual food protocols where trained personnel estimated the food consumed, which can be used as a clinically appropriate tool to measure energy and protein intake instead of weighing the meals [12,[17][18][19][20][21]. Several studies validated the use of direct visual estimation and indirect visual estimation by photography [18,19] as appropriate replacement methods.…”
