How does comorbidity influence healthcare costs? A population-based cross-sectional study of depression, back pain and osteoarthritis.

Objectives: To analyse how comorbidity among patients with back pain, depression and osteoarthritis influences healthcare costs per patient. A special focus was made on the distribution of costs for primary healthcare compared with specialist care, hospital care and drugs.

Design: Population-based cross-sectional study.

The importance of comorbidity in analysing patient costs in Swedish primary care.

Background: The objective was to explore the usefulness of the morbidity risk adjustment system Adjusted Clinical Groups (ACG), in comparison with age and gender, in explaining and estimating patient costs on an individual level in Swedish primary health care. Data were retrieved from two primary health care centres in southeastern Sweden.

Methods: A cross-sectional observational study.

Rehabilitation benefits highly motivated patients: a six-year prospective cost-effectiveness study.

Objectives: To compare the six-year outcome of a multidisciplinary rehabilitation program with continued care within primary care in terms of health-related quality of life and cost-effectiveness. Furthermore, predictors of total costs to society were examined.

Methods: A prospective, matched, controlled, six-year follow-up was designed.
