Healthcare systems are increasingly required to integrate environmental sustainability into procurement practices, yet existing procurement models often struggle to operationalize sustainability objectives across different healthcare product categories. This thesis investigates how healthcare procurement models can be redesigned to better align with environmental sustainability goals, considering the specific characteristics of medical devices, consumables, and pharmaceuticals. The study adopts a two-round Delphi methodology combining qualitative exploration and quantitative prioritisation. Round 1 identified key motivations, sustainable and circular practices, limiting factors, and procurement redesign elements. Round 2 assessed their relevance and degree of consensus using both descriptive statistics (mean, median, Interquartile Range) and inferential statistic (Kendall’s W coefficient of concordance).
