Integrated Quality and Environmental Management in Healthcare: Impacts, Implementation, and Future Directions Toward Sustainability

Healthcare institutions are under increasing pressure to deliver high-quality, patient-centered care while reducing their environmental footprint. Integrating quality and environmental management systems (ISO 9001 and ISO 14001) into a unified integrated management system (IMS) offers a potential pathway to meet these dual imperatives. This study investigates the effects of IMS implementation in three European hospitals through a comparative qualitative analysis of institutional reports, audit documentation, and performance indicators. The methodology combines a literature-informed conceptual framework with a multi-case analysis guided by four domains: environmental impact, care quality, process efficiency, and stakeholder engagement. The data were collected from institutional documentation over a six-year period (three years before and after IMS implementation), covering key indicators such as energy and water consumption, medical waste recycling, audit compliance, and patient satisfaction. The findings show that IMS adoption was associated with a 20–28% improvement in resource efficiency, increased recycling rates, and consistent gains in compliance and satisfaction metrics. These results were supported by strategic leadership, cross-functional training, and digital monitoring tools. The study concludes that IMS enhances institutional performance and sustainability while aligning healthcare operations with broader governance and policy goals. Further research is recommended to explore the long-term impacts and generalize the findings across healthcare systems.
