Quality of life of epilepsy surgery patients as compared with outpatients with hypertension, diabetes, heart disease, and/or depressive symptoms.

Abstract

Health-related quality of life (HRQOL) of 166 adults who had previously undergone surgical treatment for intractable epilepsy was compared with that of outpatients with hypertension, diabetes, heart disease, and/or depressive symptoms. Eight self-reported HRQOL domains were evaluated and compared by the RAND 36-Item Health Survey 1.0: emotional well-being, social function, role limitations due to emotional problems, energy/fatigue, pain, role limitations due to physical problems, physical function, and general health perceptions. A pictorial item on overall QOL was also administered, for a total of 9 HRQOL domains. With adjustment made for age, gender, education, and comorbid conditions, 55 completely seizure-free patients scored higher (i.e., better health) than patients with hypertension in 6 of 9 domains, higher than diabetic patients in 8 of 9, higher than those with heart disease in all 9, and higher than those with depressive symptoms in all 9 (all p < 0.05). Sixty-seven patients still having seizures with impaired consciousness scored worse than hypertensive patients in 5 domains, worse than diabetic patients in 3, and worse than heart disease patients in 2; for all 3 conditions, these domains included emotional well-being and overall QOL (p < 0.05). These 67 patients, however, scored better than patients with depressive symptoms in all 9 domains, better than those with heart disease in 2, and better than those with diabetes in 1 (all p < 0.05). Forty-four other patients had only simple partial seizures (SPS); their scores were comparable to those of diabetic and heart disease patients on mental and social health scales but were higher ("better") than those of these patients on physical health scales. HRQOL among patients who have undergone "curative" epilepsy surgery is better than that of patients who have hypertension, diabetes, heart disease, or depressive symptoms. Patients who have continued seizures with altered consciousness are worse off in terms of emotional well-being and overall QOL than all other patients, except for those with depressive symptoms.
