title: Cost of care for patients treated with lipid-lowering drugs.
abstract: OBJECTIVE
  To investigate the relationship between attainment of treatment goals with lipid-lowering therapy and healthcare costs.
  
  
  METHODS
  9789 patients who received treatment with a lipid-lowering agent at any time between 1 January 1993 and 14 April 2003.
  
  
  METHODS
  A cohort study using linkage of patient medical records from 29 Swedish primary care centres and the Swedish national inpatient register. The primary outcomes of interest were the total costs of medical care and costs of cardiovascular-related inpatient care during the year before treatment initiation and during years 1, 2 and 3 of treatment. The cost data were analysed with a two-part random-effects regression model.
  
  
  RESULTS
  Of the 9789 patients identified in the database for the study, 6316 had at least one cholesterol measurement during the year after the index prescription and were included in the analysis. 37% of the patients attained the goal of low-density lipoprotein cholesterol < 3.0 mmol/L and total cholesterol < 5.0 mmol/L. Patients who attained treatment goal had 44% higher pre-treatment costs of care. During the first year of treatment, patients who attained treatment goal had 28% higher costs of care. After the first year, costs for goal-attaining patients were 17% higher. However, the cost of cardiovascular-related inpatient care in patients attaining cholesterol treatment goal was twice as high as in patients not achieving goal before treatment start and 40% lower 2-3 years after treatment start.
  
  
  CONCLUSIONS
  Patients reaching target cholesterol levels showed a trend of cost reductions over time, whereas no such trend could be found for patients not reaching goal levels. Reductions in costs were substantial for cardiovascular-related inpatient care for patients attaining cholesterol goals compared with patients not attaining cholesterol goals.
