Background : Quality-of-Life (QoL) is often thought to be better in people with partial foot (PFA) compared to transtibial amputation (TTA)1. The available evidence is limited to descriptive data and suggests that QoL may be similar in these groups2,3. There are no studies designed to compare QoL in cohorts with PFA or TTA. These data are necessary to help inform difficult decisions about the choice of PFA or TTA from a QoL perspective.
Aim: The aim of this study was to compare QoL in people with PFA or TTA secondary to peripheral vascular disease and determine which demographic and health factors influenced QoL. Method: Persons with either PFA or TTA more than 6 months ago due to peripheral vascular disease were recruited from a major tertiary hospital. A mail-out, mail-back version of the SF-36v2 Health Survey was sent to potential participants along with the demographic section of the TAPES that we adapted to include additional questions about level of amputation and other factors known to influence QoL (e.g., retinopathy). A multivariate analysis of covariance (MANCOVA) was used to compare QoL in the PFA and TTA cohorts (n=33). A multivariate linear regression model was used to identify factors influencing QoL.
Results: Both the SF-36v2 Mental Health Component Score (MCS) and Physical Component Scores (PCS) were comparable in the PFA and TTA cohorts (Figure 1). Age, time with diabetes and presence of retinopathy significantly influenced either the SF-36v2 MCS or PCS whereas amputation level did not. Discussion & Conclusion Results of this pilot challenge long-held views that QoL is better in people living with PFA compared to those with TTA. Based on our sample, age, time living with diabetes and the presence of retinopathy had a significant influence on QoL whereas amputation level did not. Given that the level of amputation did not significantly influence QoL, surgeons and patients may instead focus their decision making on factors they can influence, such as the relative risk of ulceration and subsequent amputation.
