There are high prevalence rates of risk factors for foot ulceration in the ESRD population on haemodialysis and are comparable with those with DM. Individuals with coexisting ESRD and DM have an even greater risk for foot ulceration and LEA. This highlights the importance that regular foot screening, preventative education and treatment are necessary for patients with ESRD potentially to reduce the risk of foot ulcerations and LEAs.
Individuals with CKD frequently display risk factors for foot ulceration. Risk factors are more prevalent in individuals who also have diabetes and foot ulcers become more frequent with progression to end-stage kidney failure. Risk assessment and patient awareness strategies should therefore be extended to include all patients with CKD so as to reduce future foot ulcer development.
Off-the-shelf, extra-depth footwear significantly reduces foot pain, improves foot function and is associated with the development of fewer keratotic lesions in older people.
BackgroundIn recent years, several questionnaires have been developed for the assessment of foot health and its impact on quality of life. In order for these tools to be useful outcome measures in clinical trials, their ability to detect change over time (responsiveness) needs to be determined. Therefore, the aim of this study was to assess the responsiveness of two commonly-used questionnaires in older people with foot pain.MethodsParticipants (n = 59; 24 women and 35 men, mean age [SD] 82.3 [7.8] years) allocated to the intervention arm of a randomised controlled trial assessing the effectiveness of extra-depth footwear compared to usual care completed the Foot Health Status Questionnaire (FHSQ) and Manchester Foot Pain and Disability Index (MFPDI) at baseline and 16 weeks. Responsiveness of the FHSQ subscales (pain, function, footwear and general foot health) and MFPDI subscales (pain, functional limitation and concern about appearance) was determined using (i) paired t-tests, (ii) Cohen’s d, (iii) the standardised response mean (SRM), and (iv) the Guyatt index.ResultsOverall, the FHSQ pain subscale exhibited the highest responsiveness, as evidenced by a highly significant paired t-test (p <0.001), Cohen’s d = 0.63 (medium effect size), SRM = 0.50 (medium effect size) and Guyatt index = 1.70 (huge effect size). The next most responsive measure was the FHSQ function subscale, as evidenced by a borderline paired t-test (p = 0.050), Cohen’s d = 0.37 (small effect size), SRM = 0.26 (small effect size) and GI = 1.22 (very large effect size). The FHSQ footwear, FHSQ general foot health and MFPDI pain, functional limitation and concern about appearance subscales demonstrated lower responsiveness, with negligible to medium effect sizes.ConclusionThe FHSQ pain and function subscales were most responsive to change in older people with foot pain receiving a footwear intervention. These findings provide useful information to guide researchers in selecting appropriate outcome measures for use in future clinical trials of foot disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
