The human cost of resistance: ethical implications of coping with isolation for multidrug resistant organisms

Background Isolation of individuals colonized or infected with multidrug-resistant organisms (MDROs) is an established strategy to prevent transmission in healthcare settings. Although protective measures such as single-room placement and use of personal protective equipment are designed to safeguard vulnerable patients, growing evidence suggests that community transmission contributes substantially to the spread of certain MDROs, raising questions about the proportionality and necessity of routine isolation. At the same time, isolation has been associated with adverse effects, including reduced quality of clinical care, delays in treatment, and psychological and social burdens that may negatively influence recovery. These observations yield ethical tension between ensuring patient and public safety and respecting the autonomy and well-being of isolated individuals. Objectives This narrative review synthesizes current clinical evidence and ethical debate surrounding MDRO-related isolation practices. Sources A literature search was performed in PubMed covering publications from January 2015 through January 2025. Content We examine outcomes associated with isolation, discuss ethical implications and potential alternatives, and propose an integrative epistemic-ethical perspective that combines empirical data with normative analysis. Implications Our findings highlight the need for transparent, proportionate, and evidence-based decision making supported by interdisciplinary dialogue. Moving towards a more balanced and human-centred approach to infection prevention requires frameworks that mitigate harm, maintain safety, and promote compassionate, sustainable healthcare practice.
