This study aims to delve into the evolution, trends and implications of scientific production related to service learning (SL) and community engagement for sustainability in higher education institutions (HEIs). Because HEIs play a crucial role in achieving the sustainable development goals (SDGs), experiential learning approaches are needed to actively involve students in sustainable development.

In total, 869 publications from Web of Science and Scopus databases were analysed using a bibliometric approach that included performance analysis and science mapping. Subsequently, a systematic literature review was conducted on 118 publications, focusing on their contribution to SDGs and alignment with United Nations Educational Scientific and Cultural Organisation’s fields of expertise.

The findings reveal two significant trends: a substantial shift from curriculum development (2000–2010) to education for sustainable development (2011–2022), and the effectiveness of experiential learning teaching approaches, such as the integration of SL with community engagement and the use of innovative research methods in promoting the acquisition of sustainable development competencies. Additionally, community-based research, participatory action research and capacity development emerged as the primary topics.

While this research is based on publications from two prominent databases, it may not include significant studies published in other databases.

These findings suggest that stakeholders should incorporate experiential learning activities and innovative research approaches to enhance education in, for and from sustainability.

This study offers a fresh perspective on the intellectual framework of experiential learning teaching approaches concerning sustainability in HEIs.

Health-care organisations face many challenges in delivering safe, high-quality services while experiencing significant pressure to increase productivity and reduce costs. In this context, hospitals have implemented lean six sigma (LSS) programmes to improve their performance. This study aims to explore the application of LSS in three different non-profit Ecuadorian hospitals to comprehend the effectiveness of the methodology under this context.

A multiple-case analysis was performed in four phases: selecting the cases, defining a data collection protocol, performing a within-case analysis of each case and performing a cross-case analysis.

This research found that the LSS application positively impacts hospital performance indicators by reducing service time. The most frequently used tools include the supplier input process output customer diagram, value stream mapping, cause-and-effect diagram, five-why analysis, Gemba walk and paired two-sample test. Lastly, the results show that the most common challenges faced were lack of top management engagement, technical training and data availability.

The study is limited by the constraint of a single Latin American country from which the cases were analysed. Collaboration with external partners, like universities, and government policies promoting training in continuous improvement methodologies are crucial for success. Academic implications stress the importance of integrating soft skills in LSS implementation and engineering education.

This study shows a multiple-case analysis of LSS in a Latin American country highlighting the most commonly used tools, their impact on performance and the challenges of implementing LSS in health-care organisations in non-profit Ecuadorian hospitals.
