 The concept of feasibility is defined as capable of being done or carried out and studies which aim is to verify the feasibility intends to verify if a larger clinical trial would have a acceptable probability of success in proving the efficacy of an intervention 24. The importance of feasibility studies has been discussed since health research resources are frequently wasted in large clinical trials with interventions with small impact, studies with insufficient power, or even using measures and outcomes that do not reflect the expected changes caused by the interventions. Furthermore, these studies are essential when dealing with populations that usually lead to an increased chance of losing the follow-up or a high number of missing data, such as palliative care.
