Health‐related quality of life at healing in individuals with chronic venous or mixed‐venous leg ulceration: a longitudinal assessment
Bibliographic record
Abstract
Abstract Aims To identify factors associated with longitudinal changes in health‐related quality of life in community‐dwelling individuals with venous or mixed‐venous leg ulcers. Background Most care focuses primarily on healing; this research may additionally lead to strategies to improve quality of life. Design Data from four studies (2000–2009) were combined (2012) to examine quality of life in community‐dwelling individuals referred for care of chronic leg wounds. Methods Data collection occurred at baseline, 3, 6, 9 and 12 months or at healing and included a comprehensive clinical assessment and measures of pain (McGill), functional autonomy ( EQ ‐5D ™ ) and quality of life ( SF ‐12 TM ). Physical Component Summary and Mental Component Summary scores ( SF ‐12 TM ) were categorized by whether or not there was an improvement (≥3 points) over time. Multivariable logistic regression modelling was used to identify factors associated with improvement. Results/findings Mean age of this sample ( n = 519) was 67·5 years, 55·9% were women. Median time to healing was 70 days. Mean Physical Component Summary score increased from 37·0‐41·5; factors associated with improvement included independent mobility, family history, problems with usual activities, fewer comorbidities and higher baseline pain. Mean Mental Component Summary score improved from 50·5‐53·7; factors associated with improvement included anxiety or depression at baseline and living with others. Conclusion Chronic leg ulceration has a substantial, negative impact on health‐related quality of life. Ascertaining characteristics associated with changes in quality of life will contribute to the development of comprehensive strategies for prevention, care and improved quality of life.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
