Health state valuation in Iran: an exercise on cardiovascular diseases using visual analogue scale method

ABSTRACT

Disability Weights [DWs] are main components for computing summary measure of population health [SMPH] and economic studies. They are specific for each community, but there are no previous studies in Iran. In this study, we investigated the feasibility of health state valuation [HSV] in Iranian population. Twelve cardiologists in 3 sessions of expert panels, defined 25 states, related to cardiovascular diseases [3 major and 22 specific diseases]. From January to March 2008, 80 persons in 4 groups including physicians, patients, patients' families and general publics [each group 20], were interviewed and valuated the states, using visual analogue scale [VAS] method. SPSS[Registered] 15 for window[Registered] [SPSS Corporation, Chicago, Illinois] was used for statistical analysis. Data showed that the defined health states had various severities. All the 4 groups ranked the "3 major-diseases" and "very-mild" and "very-severe" states, similarly. Non-physicians were not able to differentiate among "valvular-diseases" and "pacemakers" properly. The reliability of responses was acceptable. VAS is an appropriate and reliable method for HSV in Iranian population. Non-physicians' opinions can be consider in major cardiac diseases. Valuation of more specific situations must perform by physicians
