Children and adolescents with epilepsy in rehabilitation centers: A French prospective transversal study

How valid are proxy assessment of mental health and sleep comorbidities of patients with epilepsy using standardized questionnaires?

BACKGROUND

The study aimed to determine the level of agreement between patients with epilepsy and their proxies when assessing psychiatric comorbidities, sleep disorders, and medication adherence using standardized questionnaires.

METHODS

This agreement study is an ancillary analysis of the PRERIES study, a matched case-control study exploring SUDEP risk factors. Controls aged 15 years and older, with active epilepsy or in remission for less than 5 years were recruited between 01/01/2011 and 03/31/2019. An interview was carried out by a trained psychologist on both the patient and a proxy-respondent. During these independent interviews, the following comorbidities were explored: psychiatric comorbidities using the MINI, the STAI- Y2 and NDDI-E scales, sleep disorders with the SDQ-SA and Epworth scales and medication adherence. Level of agreement between patient and their proxy was estimated using Gwet's AC1&2.

RESULTS

Among the 107 patient-proxy dyads recruited, proxy respondents were mainly family members (65.4%) or spouses (30.8%). Exploration of present major depression showed excellent agreement at 0.81 [0.65;0.97], as well as exploration of dysthymia at 0.96 [0.61;1]. Suicidal risk evaluation had a lesser agreement at 0.77 [0.60;0.94]. Agreement on anxiety was moderate 0.5 [0.38;0.62]. For sleep disorder, SDQ-SA presented a better agreement than the Epworth questionnaire with respectively 0.73 [0.51;0.95] and 0.45 [0.26;0.63]. For medication adherence, the overall agreement rate was excellent (0.90 [0.78;1]).

CONCLUSION

Exploration of potential risk factors through families can give valuable and relatively robust information, especially if the respondent lives with the patient, and should be retrieved, when possible, in usual clinical setting.

Socioeconomic consequences of drug-resistant epilepsy in an adult cohort from southern India

OBJECTIVE

The objective of this study was to describe the socioeconomic consequences of drug-resistant epilepsy (DRE).

METHODS

This study comprised 132 (equal males and females) consecutive patients aged ≥18 years, who fulfilled the International League Against Epilepsy (ILAE) definition for DRE, prospectively seen in a tertiary care center in South India. We used a structured questionnaire to gather relevant information.

RESULTS

The mean age was 31 (range 18-70) years. Mean age of onset of epilepsy was 17 years and mean duration of epilepsy 14 years. The most common epilepsy type and etiology were focal epilepsy and gliotic lesions secondary to perinatal insults, respectively. The average out of the pocket expenditure on antiseizure drugs annually amounted to 19% of the gross national product (GNP)/capita, which was borne by family members in more than two-thirds of the subjects. Almost 60% reported epilepsy having affected their education, 40% their employment, and 90% their marital prospects. Female patients were less often employed outside their homes and had more marital problems compared with males.

CONCLUSIONS

In addition to high seizure burden, DRE adversely affects the pursuit of higher education, employment, and marriage. Besides the direct cost of epilepsy, these issues augment both the patient and the caregiver's liability. Socioeconomic consequences of DRE are widely prevalent in developing countries, and this study highlights the need to address them.
