Understanding one health challenges in marginalized urban settings: A patient and public involvement (PPI) approach from the CHIP consortium activities across four global cities

Abstract

Background: Slum communities face health risks influenced by environmental, human, and animal health factors, particularly antimicrobial resistance (AMR). Tailored, community-driven solutions are needed to address these multifactorial health determinants. This study explores One Health challenges in urban slums using a Patient and Public Involvement (PPI) approach. Objectives: This study aims to use qualitative methods within a PPI framework to examine the social, environmental, and animal health factors contributing to AMR and other health challenges in urban slums. Focusing on One Health, we engaged slum residents in Jaipur, Jakarta, Antofagasta, and Istanbul through participatory approaches like social mapping and transect walks to identify health risks and develop intervention strategies. Methods: A PPI approach was employed to involve communities in the research process, ensuring culturally relevant insights. Data collection included social mapping, transect walks, and key informant interviews in the four cities, highlighting critical health determinants such as environmental contamination, healthcare access, and animal-related risks. Thematic analysis identified common challenges and intervention opportunities within the One Health framework. Conclusion: The study underscores the importance of PPI in addressing One Health challenges in urban slums and reveals interconnected human, environmental, and animal health risks. Engaging communities fostered trust and provided locally relevant solutions to complex health issues like AMR. Future interventions should be co-designed with communities to address social determinants like sanitation and healthcare access for sustainable outcomes.
