Working Group 3: Healthcare Patients undertakes a detailed historical examination of patient experiences and agency within European healthcare systems, drawing upon a distinct set of research inputs. Patient records and case notes, particularly from institutional settings such as hospitals and asylums, form a core primary source for understanding disease presentation and treatment trajectories. Autobiographical accounts, diaries, and correspondence of individuals experiencing illness offer invaluable subjective insights into health, suffering, and recovery. The group also analyzes advocacy literature and patient activism records, highlighting collective efforts to influence healthcare policy and practice. Literary and artistic representations of illness from various periods provide cultural context and reveal societal attitudes towards patients and their afflictions. Furthermore, demographic data and epidemiological surveys are utilized to contextualize individual experiences within broader patterns of morbidity and mortality. This multi-source methodology facilitates a nuanced historical reconstruction of patient realities, voices, and roles within the healthcare landscape.
