During a 4-year prospective multicenter study on phantom pain, phantom sensations, and residual-limb pain after an amputation, surgeons referred 225 patients to our study. The two groups of patients emerged, i.e., those who participated by filling in questionnaires over time (134 participants) and those who were followed over time through records (91 nonparticipants). We analyzed the different survival rates of participants and nonparticipants. The main reason for amputation was peripheral vascular disease. Of the patients referred, 69% survived in the 4-year period after amputation. However, we found little difference between the overall number of participants (73%) who survived compared with number of nonparticipants (63%).
