Psychological determinants of the attitude towards vascular interventions in patients with lower limb ischaemia

Abstract

BackgroundCritical lower limb ischaemia is associated with a 20% annual risk of amputation and death. It is necessary to activate pa-tients’ personal resources which comprise mental dispositions needed to effectively cope with the disease. The objective of the study was to evaluate the correlation between the attitude toward the vascular reconstruction and self-efficacy (SE), health locus of control (HLoC) and own life quality (QOL) assessment in patients with critical lower limb ischaemia.Participants and procedureThe study involved 64 patients with critical lower limb ischaemia (Rutherford 4 and 5), 26 women and 38 men. Four scales were applied during primary admission: the Generalized Self-Efficacy Scale; the Satisfaction with Life Scale; the Multidimensional Health Locus of Control Scale; and the visual scale revealing attitude to vascular reconstruction.ResultsThe attitude to the vascular reconstruction was positive (M = 8.50). The lowest grades were given by those hospitalised several times during follow-up (M = 8.30); women expressed low grades (M = 7.71). An overall positive correlation was found between the positive attitude to the surgery and self-efficacy (p = .012), internal HLoC (p = .041) and external locus (p = .026). In the patients who died within six months from baseline assessment, no correlations were found. In subjects with no readmission, a correlation was found between positive attitude to surgery and the external personal HLoC (p = .023). In patients with subsequent readmissions, a correlation was found between the originally positive attitude to the surgery and poor self-efficacy (p = .009).ConclusionsPatients with weak mental dispositions cannot cope with difficult situations and show a tendency to experience strong emotions, concentrating on their deficiencies, resulting in decreased motivation and feeble engagement in treatment. Poor mental disposition influences the final outcome of the vascular reconstruction.
