P21 The relationship between employment status, work productivity and quality of life among patients with COPD: Cross-sectional analysis of the Birmingham COPD Cohort
Bibliographic record
Abstract
<h3>Introduction</h3> Health related quality of life (HRQoL) tends to be lower among COPD patients, as a result of associated symptoms, comorbidities and the impact of disease on daily life. However, little is known about the association between employment status and HRQoL among COPD patients. <h3>Aims</h3> We examined the relationships between HRQoL and employment status and occupational performance among patients with COPD. <h3>Methods</h3> 2000 patients with COPD from primary care are being recruited into the Birmingham COPD cohort study. In addition to clinical data, employment status, work performance and HRQoL were assessed. Work performance was measured using the SPS-6 presenteeism questionnaire. HRQoL was measured using the St George’s respiratory questionnaire (SGRQ-C). Interim baseline data was used to assess associations between HRQoL and employment status and HRQoL and occupational performance. Multivariate analyses were used to adjust for potential confounders. Model 1 adjusted for age, sex and smoking status. Model 2 additionally adjusted for disease severity (GOLD stage), number of co-morbidities and MRC dyspnoea score. <h3>Results</h3> Of the 1094 patients recruited, 14.6% (n = 160) were in work. <b>Employment status</b>: Model 1 showed that poorer quality of life was associated with lower likelihood of being in employment (OR = 0.98, 95% CI 0.96–0.99), but the effect was not seen in model 2 (OR = 1.00, 95% CI 0.99–1.02). <b>Work performance</b>: increased work performance (presenteeism) was associated with a higher quality of life in both models (B coefficient 0.13, 95% CI 0.08–0.18 and 0.12, 95% CI 0.05–0.19 in models 1 and 2 respectively). <h3>Conclusions</h3> The association between presenteeism and HRQoL has not previously been assessed in a UK COPD working population. Our findings show that after adjusting for all relevant confounders, employment status is not associated with quality of life. However, for those at work, a better quality of life is associated better work performance.

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.
