[NEmecum: digital tool to help the prescription and dispensation of enteral nutrition and infant nutrition formulas. Development, diffusion and analysis of results and usage data].

INTRODUCTION: there is a wide variety of enteral nutrition and infant formulas or preparations. Consultation of related information must be performed using the tools provided by each laboratory, which makes critical vision and comparison between them very arduous.

OBJECTIVE: to describe the development of NEmecum as the first website that allows a directed and independent search for enteral nutrition formulas and infant formulas, to analyze the current nutritional range in Spain, and to evaluate the data usage of the tool.

METHODS: the structure of a database that unifies the parameters of all formulas was developed, and the nutritional range was analyzed. Subsequently, the main search algorithms were selected and the digital tool was codified. Intensive dissemination was performed and the impact was evaluated. The profile of users and registered centers and the data usage of the tool were analyzed, and its usability was evaluated using the System Usability Scale (SUS) questionnaire.

RESULTS: a free-access responsive website (https://nemecum.com) that allows searches based on pre-established search filters was obtained. This tool allows for a detailed analysis of the extensive range of nutritional formulas in Spain by observing a wide variety of formulas with similar characteristics. The dissemination campaign managed to increase its use exponentially, currently reaching 1,370 users and 79 registered centers. Usability was rated as excellent.

CONCLUSION: the development of the NEmecum represents a revolution in the search and consultation of the characteristics of enteral nutrition formulas and infant preparations.
