The walking estimated limitation stated by history (WELSH): a visual tool to self-reported walking impairment in a predominantly illiterate population.

ABSTRACT:

Background

The prevalence of cardiovascular diseases is increasing in low-income countries. Various questionnaires to estimate walking capacity in patients are available in multiple languages but they are not suitable for illiterate patients.

Objective

The walking estimated limitation stated by history (WELSH) tool aims at rating individual walking disability using only drawings and four items.

Methods

A six-month prospective study was performed on new patients referred to the Department of Cardiology at the Centre Hospitalier Universitaire Sourô Sanou in Bobo-Dioulasso, Burkina Faso. We administered the WELSH tool after a short oral presentation in the patient's language or dialect. Thereafter, patients performed a six-minute walking test in the hospital corridor under the supervision of a nurse who was blinded to the results of the WELSH score. We performed a step-by-step multilinear regression analysis to determine the factors predicting maximal walking distance (MWD).

Results

There were 40 female and 10 male patients in this study. Their ages ranged from 54.8 ± 10.7 years. Only 32% of the patients had attended primary school. Most patients were classified as stage I to III of the New York Heart Association (NYHA) classification. The objective measurement of MWD during a six-minute walking test showed no association with the subjects' educational level, body mass index, NYHA stage or gender, but a significant correlation with the WELSH scores. The Spearman r-value for the WELSH score-to-MWD relationship was 0.605 (p < 0.001).

Conclusions

The WELSH tool is feasible and correlated with measured MWD in a population of predominantly illiterate patients.

Project description:ObjectivesPatient-reported outcome measures can facilitate the assessment of walking impairment in peripheral artery disease patients with intermittent claudication in clinical trials and practice. The aim of this study was to test the psychometric properties of the German version of the 'Walking Estimated-Limitation Calculated by History' (WELCH) questionnaire.MethodsThe assessed properties included feasibility, test-retest reliability, construct validity (i.e., convergent, divergent and known-groups validity) and responsiveness using classic psychometric methods. Psychometric properties were tested as part of a randomized controlled home-based exercise trial for patients with symptomatic peripheral artery disease at Fontaine stage IIA/B.ResultsAnalyses were conducted in subgroups of 1,696 patients at baseline and 1,233 patients at 12-month follow-up (i.e., post-intervention) who completed the WELCH along with a battery of other self-report measures. The WELCH did not exhibit relevant floor or ceiling effects (< 15% achieved lowest or highest possible scores), showed evidence for good test-retest reliability (ICC = .81, 95% CI [.71-.88]) and was found to be well suited for self-completion by patients (< 5% missing data per item). WELCH scores showed moderate to strong correlations with related measures of walking impairment at both time points (Walking Impairment Questionnaire: r = .56 - .74; VascuQoL-25 activity subscale: r = .61 - .66) and distinguished well among patients with poor and high quality of life when adjusting for confounders (t = 13.67, p < .001, d = .96). Adequate divergent validity was indicated by a weaker correlation between the WELCH and general anxiety at both time points (GAD-7: r = - .14 to - .22). The WELCH improved by 6.61 points (SD = 17.04, 95% CI [5.13-8.10], d = 0.39) in response to exercise treatment and was able to identify large clinically important improvements observed on the walking distance (AUC = .78, 95% CI [.71-.84]) and speed subscales (AUC = .77, 95% CI [.68-.86]) of the Walking Impairment Questionnaire.ConclusionsThe WELCH is considered a feasible, reliable and valid patient-reported outcome measure for the measurement of walking impairment in patients with peripheral artery disease. The WELCH showed evidence for responsiveness to changes in walking impairment, yet further studies are warranted to conclusively determine the WELCH's ability to detect intervention effects.

Project description:BackgroundOne of the most economically important areas within the Welsh agricultural sector is sheep farming, contributing around £230 million to the UK economy annually. Phenotypic selection over several centuries has generated a number of native sheep breeds, which are presumably adapted to the diverse and challenging landscape of Wales. Little is known about the history, genetic diversity and relationships of these breeds with other European breeds. We genotyped 353 individuals from 18 native Welsh sheep breeds using the Illumina OvineSNP50 array and characterised the genetic structure of these breeds. Our genotyping data were then combined with, and compared to, those from a set of 74 worldwide breeds, previously collected during the International Sheep Genome Consortium HapMap project.ResultsModel based clustering of the Welsh and European breeds indicated shared ancestry. This finding was supported by multidimensional scaling analysis (MDS), which revealed separation of the European, African and Asian breeds. As expected, the commercial Texel and Merino breeds appeared to have extensive co-ancestry with most European breeds. Consistently high levels of haplotype sharing were observed between native Welsh and other European breeds. The Welsh breeds did not, however, form a genetically homogeneous group, with pairwise F ST between breeds averaging 0.107 and ranging between 0.020 and 0.201. Four subpopulations were identified within the 18 native breeds, with high homogeneity observed amongst the majority of mountain breeds. Recent effective population sizes estimated from linkage disequilibrium ranged from 88 to 825.ConclusionsWelsh breeds are highly diverse with low to moderate effective population sizes and form at least four distinct genetic groups. Our data suggest common ancestry between the native Welsh and European breeds. These findings provide the basis for future genome-wide association studies and a first step towards developing genomics assisted breeding strategies in the UK.
