Ethical Limitations of Evidence-Based Design: A Critical Analysis of UK Practices

Evidence-based design (EBD) has significantly advanced healthcare environments by utilizing empirical research to improve outcomes related to safety, efficiency, and satisfaction. Its success in addressing issues with ethical implications, such as privacy and infection control, inevitably raises the question of its sufficiency in creating a fully ethical environment. This article critically examines the ethical scope of EBD within the UK context, arguing that its empirical methodology encounters significant limitations. Specifically, its predominant focus on quantitative metrics—medical, financial, and satisfaction-based—fails to adequately address the inherent dignity of nonautonomous patients and complex ethical tradeoffs where principles like justice or safety may not align with user contentment. An analysis of professional codes and NHS guidelines reveals they are insufficient to bridge this gap, being either too narrow in scope or too generalized. Consequently, this article proposes the integration of a complementary, principled ethical framework. It highlights the potential of Martha Nussbaum's Capabilities Approach to complement EBD's empirical strengths by providing a robust, dignity-oriented model for navigating areas where quantitative evidence is lacking. Ultimately, bridging EBD's rigor with such an ethical lens offers a promising path toward creating healthcare environments that are not only effective but also profoundly respectful of fundamental patient rights.
