Psycho-haematology Research Unit

The Psycho-haematology Research Unit (PRU-UH) carries out primary research and consultancy on psychological factors in blood disorders such as haemophilia, Sickle cell disease, Thalassemia and Von Willebrand disease.

Psychological factors that can play a role in these conditions include adherence to medicine or other medical advice, pain perception and management, beliefs about the condition, beliefs about the treatment, social support, quality of life and many other factors.

We collaborate with centres that treat blood disorders to address issues that are raised by patients and health care professionals, ensuring that our work is meaningful, relevant and has clinical impact.
