Methods
We conducted 30 semi-structured interviews with 15 doctors and 15 nurses and observations of 104 encounters treating malign melanoma (38 encounters), urological cancer (36 encounters) and lung cancer (30 encounters) from May 2019 to October 2019. We explored HPs’ barriers to registering patients’ social data in the medical record, including structural conditions, practices and attitudes. We chose these treatment groups to reflect differences in socio-economic distribution (1).
