title: Prevalence of all-cause and diagnosis-specific disability pension at the time of first coronary revascularisation: a population-based Swedish cross-sectional study.
abstract: BACKGROUND
  Although coronary revascularisation by coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI) is well documented, scientific knowledge on disability pension (DP) at the time of revascularisation is lacking. The aim was to investigate the prevalence of all-cause and diagnosis-specific DP at the time of a first coronary revascularisation, accounting for socio-demographic and medical factors.
  
  
  METHODS
  A population-based cross-sectional study using Swedish registers was conducted including all 65,676 patients (80% men) who when aged 30-63 years, within 1994-2006, had a first CABG (n = 22,959) or PCI (n = 42,717) and did not have old-age pension. Associations between socio-demographic and medical factors and the probability of DP were estimated by odds ratios (OR) with 95% confidence intervals (CI) using logistic regression analyses.
  
  
  RESULTS
  The prevalence of DP at time of revascularisation was 24%, mainly due to musculoskeletal diagnoses. Sixty-two percent had had DP for at least four years before the revascularisation. In the multivariable analyses, DP was more common in women (OR: 2.40; 95% CI: 2.29-2.50), older patients (50-63 years); especially men aged 60-63 years with CABG (OR: 4.91; 95% CI: 4.27-5.66), lower educational level; especially men with PCI (OR: 2.96; 95% CI: 2.69-3.26), patients born outside Sweden; especially men with PCI (OR: 2.11; 95% CI: 1.96-2.27), and in women with an indication of other diagnoses than acute coronary syndrome (ACS) or stable angina pectoris for PCI (OR: 1.72; 95% CI: 1.31-2.24).
  
  
  CONCLUSIONS
  About a quarter had DP at the time of revascularisation, often due to musculoskeletal diagnoses. More than half had had DP for at least four years before the intervention. DP was associated with female gender, older age, lower educational level, and being born outside Sweden.
