Abstract

Motor neurone disease (MND) has a severe impact on patient quality of life, especially in later stages of the disease. This study assesses the health-related quality of life (HRQL) of MND patients, and for the first time elicits health state values from patients for their present health state. A structured interview was conducted with 77 patients. Patients completed a disease specific health status measure (ALSAQ-40), a generic health status measure (EuroQol EQ-5D), a visual analogue scale (VAS) and a standard gamble (SG) exercise. The ALSAQ-40 was sensitive to disease severity. Patients' mean VAS rating of their own health ranged from 0.74 for stage 1 (early) disease severity (n = 15), to 0.37 for stage 4 (late stage) disease severity (n = 19). Utilities elicited via SG varied from a mean of 0.79 for stage 1 disease severity to a mean of 0.45 for stage 4 disease severity. The EQ-5D derived single index ranged from a mean of 0.63 for stage 1 disease severity to a mean of −0.01 for stage 4 disease severity. This study demonstrates that it is feasible and practical to obtain health state values from MND patients and it provides evidence that patients place a high value on their HRQL, even in cases where health status is very poor.
