„Was hab’ ich?“ (WHI) has been working in the field of physician-patient communication for over 10 years, providing thousands of patients with easy-to-understand health information in numerous ways. The non-profit-organisation cooperates with a wide network of other organisations and players within the healthcare sector. Our prior work has shown that written, plain-language documents received directly from the respective hospital are especially helpful to ensure continuous information flow to children, spouses or other relatives acting as informal caregivers.
