Ethical and legal aspects of consent and patient safety in the UK healthcare system

In this chapter, we examine the intersection of ethics, law and patient safety in UK healthcare system, focusing on informed consent. The legal shift from clinician-centred standards like the Bolam test to patient-centred approaches was cemented by the 2015 Montgomery v Lanarkshire ruling, which emphasised the duty to inform patients of material risks from their perspective. Ethical principles – autonomy, beneficence, non-maleficence, and justice – underpin healthcare practice, urging clinicians to empower patients and engage them meaningfully in decisions. Legal frameworks like the Mental Capacity Act 2005 guide decisions for those lacking capacity, including children and vulnerable groups. Informed consent is a dynamic, relational process requiring respectful, clear communication and attention to individual values. Challenges such as technological advances, cultural differences and communication barriers demand nuanced approaches. We also explore consent limits through examples like elective surgeries and R v Brown , raising questions about personal autonomy versus societal protection. Ethical concerns arise in areas like body modification and gender-affirming care. Patient safety is framed as an ethical imperative, supported by the duty of candour, openness, safeguarding and whistleblowing. Relational ethics and person-centred care are highlighted. The authors conclude that combining ethical and legal knowledge is vital to delivering compassionate, transparent and safe care.
