Key result
Mood disorders linked to reduced HRQoL, ranking second behind chronic pain in annual QALY losses.
Why the study?
The burden of disease from mental disorders and chronic physical conditions in primary care and their impact on health-related quality of life and QALY losses needed quantification.

Mood disorders and pain are the leading causes of quality-adjusted life-year losses among primary care patients.
May inform primary care resource allocation for mood disorders; leaves open whether interventions improve QALYs.
BACKGROUND: The World Health Organization (WHO) has stated that the three leading causes of burden of disease in 2030 are projected to include HIV/AIDS, unipolar depression and ischaemic heart disease. AIMS: To estimate health-related quality of life (HRQoL) and quality-adjusted life-year (QALY) losses associated with mental disorders and chronic physical conditions in primary healthcare using data from the diagnosis and treatment of mental disorders in primary care (DASMAP) study, an epidemiological survey carried out with primary care patients in Catalonia (Spain). METHOD: A cross-sectional survey of a representative sample of 3815 primary care patients. A preference-based measure of health was derived from the 12-item Short Form Health Survey (SF-12): the Short Form-6D (SF-6D) multi-attribute health-status classification. Each profile generated by this questionnaire has a utility (or weight) assigned. We used non-parametric quantile regressions to model the association between both mental disorders and chronic physical condition and SF-6D scores. RESULTS: Conditions associated with SF-6D were: mood disorders, beta = -0.20 (95% CI -0.18 to -0.21); pain, beta = -0.08 (95%CI -0.06 to -0.09) and anxiety, beta = -0.04 (95% CI -0.03 to -0.06). The top three causes of QALY losses annually per 100 000 participants were pain (5064), mood disorders (2634) and anxiety (805). CONCLUSIONS: Estimation of QALY losses showed that mood disorders ranked second behind pain-related chronic medical conditions.

Bellón et al. (2010) conducted a cross-sectional in Mental disorders and chronic physical conditions (n=3,815). Mood disorders vs. Absence of mood disorders was evaluated on SF-6D score (health-related quality of life) (b = -0.20, 95% CI -0.21 to -0.18, p=<0.001). Mood disorders were significantly associated with reduced health-related quality of life (b = -0.20) and ranked second behind chronic pain in annual quality-adjusted life-year losses.
