Medication-Related Quality of Life in Thai Epilepsy Patients

This study aimed to assess medication-related quality of life in Thai patients with epilepsy. The second objective was to evaluate the associations between the medication therapy-related quality of life and patient characteristics.

This was a cross-sectional study. A convenience sample of 173 outpatients with epilepsy was recruited from a university hospital in Bangkok, Thailand. Inclusion criteria were aged 18 or over who were continuously taking an epileptic drug for at least 3 months, understanding Thai language, and willing to participate in the study. The Patient-Reported Outcomes Measure of Pharmaceutical Therapy for Quality of Life (PROMPT-QoL) was utilized to measure the medication therapy-related quality of life. Pearson's correlation coefficients and stepwise multiple linear regressions were employed to assess the relationships between eight PROMPT-QoL domain scores and patient demographic and clinical characteristics.

Mean age was 36.4±9.5 years and approximately 57% were female. Among eight domains of the PROMPT-QoL, the therapeutic relationships with health care providers and psychological impacts of medication use domains yielded the highest (77.9) and lowest (61.9) mean scores, respectively. Seven out of eight PROMPT-QoL domain scores were considered as moderate-to-good. Age, gender, duration of epilepsy, seizure frequency, and treatment preference were significantly associated with PROMPT-QoL domain scores in multivariate linear regression analyses.

This study showed that Thai patients with epilepsy had moderate-to-good medication therapy-related quality of life. Healthcare providers should pay more attention to patients' psychological impacts of antiepileptic drugs and those with characteristics related to lower medication therapy-related quality of life.
