Assessment of health-related quality of life and influencing factors using QOLIE-31 in Japanese patients with epilepsy.
The aim of epilepsy treatment is not only to eliminate seizures, but also to improve health-related quality of life (HRQOL). We conducted a postal self-administered survey of HRQOL for Japanese patients using the Quality of Life in Epilepsy inventory (QOLIE-31), Version 1.0, and analyzed factors influencing their quality of life (QOL). Data from 599 analyzable patients were evaluated and a number of factors influencing QOL were identified, including severity and frequency of seizures, seizure control, type of epilepsy, contributing events such as injuries and falls during seizures, number of antiepileptic drugs, employment status, and surgical outcome. These findings suggest that comprehensive management of the patient should be emphasized. Consideration of all the results led to classification of these factors as one of two types: "all or nothing" and "linear." With respect to "all or nothing" factors (e.g. "daytime remarkable seizures"), patients may not be able to improve their QOL unless these factors can be completely controlled. Comparison of each score on the QOLIE-31 subscales with published data revealed that the scores for the subscale Medication Effects were markedly low.
