Food waste in hospitals: implications and strategies for reduction: a systematic review

Abstract

PurposeThe purpose of the study is to comprehensively and extensively investigate food waste in hospitals and the environmental and economic effects it imposes on society. By knowing the reasons and factors affecting the creation of such wastes, it is possible to help reduce these effects.Design/methodology/approachThis study was conducted by systematic search in PubMed, Scopus, Science Direct and Web of Science databases.FindingsThe results suggest that high-income countries such as Denmark, Sri Lanka, Portugal and Spain have more significant amounts of food waste than low-income countries like Turkey. The main reasons for food waste include inadequate food quality, low patient appetite and issues with the dining environment. Therefore, it is crucial to address these root causes to minimize food waste and alleviate the burden on the environment.Research limitations/implicationsThe study relies primarily on secondary data analysis and does not include original food waste audits or interviews with hospital staff. While the literature review provides useful background, conducting first-hand audits and interviews could strengthen the study by providing more current, contextualized and granular insights into food waste in hospitals. The lack of primary data collection limits the ability to make hospital-specific recommendations or quantify the opportunity for improvement. Additionally, the focus is on general frameworks rather than interventions tailored to the needs and constraints of hospitals in low- and middle-income regions. More region-specific research would be needed to understand nuanced challenges and develop customized solutions suitable for implementation in those settings.Originality/valueEffective measures can be taken to make policies and determine appropriate solutions to reduce these wastes. By recognizing the problems in structures, one can take steps to reduce global warming and waste of national funds.
