title: Incidence and management of intermittent claudication in primary care in The Netherlands.
abstract: OBJECTIVE
  To study the incidence and management of intermittent claudication in primary care.
  
  
  METHODS
  In a longitudinal survey among 161 general practitioners (GPs) all incident diagnoses of intermittent claudication (IC) were selected and available information on GP management was studied.
  
  
  METHODS
  Dutch National Survey of Morbidity and Interventions in General Practice.
  
  
  METHODS
  74153 patients aged 55 years and over.
  
  
  METHODS
  Age- and sex-specific incidence rates.
  
  
  RESULTS
  The overall incidence rate of IC was 6.4 per 1000 person years (95% confidence interval (CI) 5.3-7.7). Incidence rate in creased from 4.0 per 1000 person years in men aged 55-59 to 12.9 per 1000 person years in men aged over 85, and for women in the same age categories from 3.3 per 1000 person years to 8.2 per 1000 person years, respectively. Of the 117 incident cases of IC, 43 (37%) were referred to a hospital specialist. In 55 cases (47%), drugs were prescribed by the GP and in 101 cases (86%) the GP gave advice, notably pertaining to exercise and cessation of smoking.
  
  
  CONCLUSIONS
  The incidence rate of IC in primary care is high in both men and women, and clearly increases with age. Only a minority of patients are referred to a hospital specialist, while the vast majority receive lifestyle advice.
