title: Trends in the first decade of 21st century healthcare utilisation in a rheumatoid arthritis cohort compared with the general population.
abstract: OBJECTIVE
  To study 21st century trends in healthcare utilisation by patients with rheumatoid arthritis (RA) compared with the general population.
  
  
  METHODS
  Observational cohort study. Using Swedish healthcare register data, we identified 3977 Region Skåne residents (mean age in 2001, 62.7 years; 73% women) presenting with RA (International Classification of Diseases-10 codes M05 or M06) in 1998-2001. We randomly sampled two referents from the general population per RA patient matched for age, sex and area of residence. We calculated the year 2001-2010 trends for the annual ratio (RA cohort/referents) of the mean number of hospitalisations and outpatient clinic visits.
  
  
  RESULTS
  By the end of the 10-year period, 62% of patients and 74% of referents were still alive and resident in the region. From 2001 to 2010, the ratio (RA cohort/referents) of the mean number of hospitalisations for men and women decreased by 27% (p=0.01) and 28% (p=0.004), respectively. The corresponding decrease was 29% (p=0.005) and 16% (p=0.004) for outpatient physician care, 34% (p=0.009) and 18% (p=0.01) for nurse visits, and 34% (p=0.01) and 28% (p=0.004) for physiotherapy. The absolute reduction in number of hospitalisations was from an annual mean of 0.79 to 0.69 in male patients and from 0.71 to 0.59 in female patients. The corresponding annual mean number of consultations in outpatient physician care by male and female RA patients changed from 9.2 to 7.7 and from 9.9 to 8.7, respectively.
  
  
  CONCLUSIONS
  During the first decade of the 21st century, coinciding with increasing use of earlier and more active RA treatment including biological treatment, overall inpatient and outpatient healthcare utilisation by a cohort of patients with RA decreased relative to the general population.
