Daratumumab Provided at Home Experience An Open, Single-center, Mixed-method Project.

Multiple myeloma (MM) is the second most common hematological disease in Denmark with an incidence of approximately 350 diagnosed cases per year. There is no curative treatment yet, but usually the disease is very sensitive to treatment, and patients have periods of varying length, where they do not require treatment. Thus the prognosis for MM has improved over recent years, and the rate of survival has been extended for both younger and elderly patients. With the increasing specialization and centralization that will occur in the coming years, some patients will have very long transport times to the hospital. When patients go to the hospital only to receive their anticancer therapy, their visits are relatively short and the amount of time spend on transportation might appear disproportionate. The frequent hospital appointments increase the patient's exposure for bacteria and viruses which should be calculated as a potential risk. Furthermore if the patient is an active part of the labor market, it can be challenging to request freedom to hospital visits. It is thus possible to provide the treatment at home, but it is unknown what significance it has for patients, relatives and health professionals as well as for the economy it is thus possible to provide the treatment at home, but it is unknown what significance it has for patients, relatives and health professionals as well as for the economy. The aim of this project is to investigate the home administration of Daratumumab SC reported by both patients and healthcare professionals compared to the hospital administration setting. Furthermore, this project investigates the hypothesis that the home administration of Daratumumab potentially can reduce the time associated with the administration, thereby, resulting in a socio-economic gain. The aim for this study: We want to examine patients 'and healthcare professionals' perspectives, the organizational and the socio economic aspects of administering subcutaneous Daratumumab in their own home to patients with multiple myeloma, and to illuminate the benefits and challenges of this.
