Personalization in mitigating food waste and costs in hospitalization

Organization of food services within hospitals has been identified as a determinant of hospitalized patients' nutritional intake and associated food waste. Whereas hospital food service systems in the Netherlands traditionally consist of 3 fixed mealtimes each day, we recently implemented a new 3-channel concept that provides patients the opportunity to order extra meals or snacks in-between their 3 main mealtimes or even have dinner with their visitors in a bistro located on their ward.

This study investigates the impact of transitioning from a traditional paper-based to a patient-centered, digital hospital food service system on food waste production patterns and its associated financial implications.

Plate waste (served but uneaten food) measurements were performed at baseline for all served meals during a one-week period within the traditional system and follow-up measurements were conducted annually after implementation of the new system during 3 consecutive years. Measurements were conducted at two hospital floors, each comprising four wards. Average grams of plate waste per served meal, daily meal frequency per patient and the associated production and disposal costs of the collected waste were calculated and compared between the two systems.

A total of 4361 meals served within the traditional system were compared with 7815 meals served within the new digital system. Meal frequency increased from an average of 2.5 meals per patient per day in the old system to an average varying between 3 and 3.3 meals per patient per day in the consecutive years. Within the traditional system, average plate waste was 81 grams per served meal, whilst it ranged between 33 and 49 grams per served meal during the following years, with the 3-channel concept in place (p < 0.001, p = 0.010). Dinner demonstrated the largest reduction in plate waste at all measurement points. Following this reduction of plate waste, estimated associated costs of plate waste production and disposal decreased in a similar pattern.

Transitioning from a traditional, paper based to a patient-centered and digital hospital catering system results in significantly higher daily meal frequency and less food waste per served meal.
