Self-Management education for adults with poorly controlled epILEpsy [SMILE (UK)]: a randomised controlled trial

BACKGROUND

Epilepsy is a common neurological condition resulting in recurrent seizures. Research evidence in long-term conditions suggests that patients benefit from self-management education and that this may improve quality of life (QoL). Epilepsy self-management education has yet to be tested in a UK setting.

OBJECTIVES

To determine the effectiveness and cost-effectiveness of Self-Management education for people with poorly controlled epILEpsy [SMILE (UK)].

DESIGN

A parallel pragmatic randomised controlled trial.

SETTING

Participants were recruited from eight hospitals in London and south-east England.

PARTICIPANTS

Adults aged ≥ 16 years with epilepsy and two or more epileptic seizures in the past year, who were currently being prescribed antiepileptic drugs.

INTERVENTION

A 2-day group self-management course alongside treatment as usual (TAU). The control group received TAU.

MAIN OUTCOME MEASURES

The primary outcome is QoL in people with epilepsy at 12-month follow-up using the Quality Of Life In Epilepsy 31-P (QOLIE-31-P) scale. Other outcomes were seizure control, impact of epilepsy, medication adverse effects, psychological distress, perceived stigma, self-mastery and medication adherence. Cost-effectiveness analyses and a process evaluation were undertaken.

RANDOMISATION

A 1 : 1 ratio between trial arms using fixed block sizes of two.

BLINDING

Participants were not blinded to their group allocation because of the nature of the study. Researchers involved in data collection and analysis remained blinded throughout.

RESULTS

The trial completed successfully. A total of 404 participants were enrolled in the study [SMILE (UK), n = 205; TAU, n = 199] with 331 completing the final follow-up at 12 months [SMILE (UK), n = 163; TAU, n = 168]. In the intervention group, 61.5% completed all sessions of the course. No adverse events were found to be related to the intervention. At baseline, participants had a mean age of 41.7 years [standard deviation (SD) 14.1 years], and had epilepsy for a median of 18 years. The mean QOLIE-31-P score for the whole group at baseline was 66.0 out of 100.0 (SD 14.2). Clinically relevant levels of anxiety symptoms were reported in 53.6% of the group and depression symptoms in 28.0%. The results following an intention-to-treat analysis showed no change in any measures at the 12-month follow-up [QOLIE-31-P: SMILE (UK) mean: 67.4, SD 13.5; TAU mean: 69.5, SD 14.8]. The cost-effectiveness study showed that SMILE (UK) was possibly cost-effective but was also associated with lower QoL. The process evaluation with 20 participants revealed that a group course increased confidence by sharing with others and improved self-management behaviours.

CONCLUSIONS

For people with epilepsy and persistent seizures, a 2-day self-management education course is cost-saving, but does not improve QoL after 12-months or reduce anxiety or depression symptoms. A psychological intervention may help with anxiety and depression. Interviewed participants reported attending a group course increased their confidence and helped them improve their self-management.

FUTURE WORK

More research is needed on self-management courses, with psychological components and integration with routine monitoring.

Knowledge, attitude and practice of parents regarding pediatric antiepileptic drug therapy

Objectives To evaluate the parental knowledge, attitude and practice (KAP) regarding the antiepileptic medication therapy in childhood.

Methods This study was carried out over a period of 10 months in the division of Pediatric Neurology of Amrita Institute of Medical Sciences. The cohort of patients was selected randomly meeting the inclusion and exclusion criteria. Parents' KAP regarding epilepsy and antiepileptic drug therapy was assessed using a questionnaire prepared by the authors and patient adherence towards antiepileptic drug therapy by using Pediatric Epilepsy Self-Management Questionnaire (PEMSQ).

Results A total of 123 patients were selected and enrolled in the study. Seventy eight percent of the respondents knew that epilepsy is a brain disorder, while only 6% of them were aware about all the treatment options. The scoring in the domain of “Disease and Treatment Knowledge & Expectations of parents” was found to be significantly low (69.07%) when compared to other domains in the PEMSQ. Although socioeconomic status did not correlate with knowledge score of the parents (p = 0.216), it was significantly related to adherence (p = 0.042).

Conclusion In this cohort, even though the parents had a fair knowledge about the nature of epilepsy, they were found to be less aware about its characteristics, causes and prognosis. The awareness about the nature and duration of treatment, its objectives, use of drugs, their side effects and importance of adherence to drug regimen was found to be significantly low with a potential for affecting the therapeutic outcome. Special awareness programs for parents of children with epilepsy may be needed to reduce the knowledge gaps in the management of epilepsy and to ensure compliance and optimal therapeutic outcomes.

Knowledge about epilepsy in university health students: A multicenter study

Even with economic development and improvements in health care around the world, it is estimated that nowadays, 50 million people have epilepsy. It is one of the most prevalent neurological diseases, yet it is still surrounded by prejudice, stigma, lack of awareness, and wrong attitudes of the population towards the disease. The aim of this study was to evaluate and compare the knowledge about epilepsy in health students from different countries: Brazil, Argentina, Portugal, United States, and South Africa. Students were asked to complete a survey regarding knowledge about epilepsy (the Epilepsy Knowledge Questionnaire). One hundred and two students participated, 62.2% of them were female. Portuguese students had significantly higher values than the American ones (p=0.025). Regarding the medical aspects, on average, students hit 63.8% of the questions, and the students from Portugal had significantly higher average than the ones from the United States (p=0.0007). Statements with lower percent of correct answers were about pathophysiology, medication, and treatment of the disease. There were no differences between the scores obtained by the students of each country in the social aspects of the disease. Statements with higher percent of mistakes were about sports practice, labor, proceedings in case of convulsion, and ability to drive vehicles. General knowledge of senior health students about epilepsy was considered low, however, regarding the medical aspects of the disease, students from Brazil and Portugal exhibited a slightly superior knowledge. Changing the way of seeing and treating people with epilepsy brings, as a consequence, increased opportunities for these people in different sectors of society.

Epilepsy or a Seizure Disorder? Parental Knowledge and Misconceptions About Terminology

OBJECTIVE

To assess primary caregiver understanding of the term epilepsy.

STUDY DESIGN

A cross-sectional telephone survey evaluated understanding of the term epilepsy among primary caregivers of children diagnosed with epilepsy at an urban referral center during a 24-month period. Three measures of primary caregiver understanding were used: (1) identifying if their child had a seizure disorder, epilepsy, or both; (2) providing an open-ended definition of epilepsy; and (3) selecting from a multiple-choice definition of epilepsy. Caregivers with 3 correct answers were assigned the greatest knowledge score. Associations with possible predictor variables were analyzed.

RESULTS

Caregivers for 75 of 116 eligible patients were contacted successfully. Of those, 55 of 75 met eligibility criteria; 45 of the eligible caregivers completed the survey. Twenty-six of 45 caregivers (58%) identified that their child had both a seizure disorder and epilepsy, 5 of 45 (11%) provided a correct open-ended definition of epilepsy, and 16 of 45 (36%) selected the correct multiple-choice definition. Fifteen caregivers (33%) had no correct answers. Seventeen (38%) answered 1, 9 (20%) answered 2, and 4 (9%) answered all 3 measures correctly. Caregivers with greater self-rated understanding had greater epilepsy knowledge scores (P = .008). Having a child neurologist as the first person to discuss the diagnosis with the caregiver also predicted a greater epilepsy knowledge score (P = .04).

CONCLUSIONS

Most primary caregivers of children with epilepsy have a poor understanding of the term epilepsy. Changes are needed in how we educate caregivers about the meaning of this term.

Association of knowledge about epilepsy with mood and self-efficacy in Korean people with epilepsy

PURPOSE

We determined the level of knowledge about epilepsy in Korean people with epilepsy (PWE) and evaluated whether this is associated with self-efficacy, perceived stigma, anxiety, and depressive mood in these patients.

METHODS

This was a cross-sectional multicenter study. A total of 530 PWE participated from 31 secondary or tertiary hospitals in Korea. Knowledge about epilepsy was assessed using 34 medical items (EKP-M) of the Epilepsy Knowledge Profile-General. Additional questionnaires included the Epilepsy Self-Efficacy Scale (ESES), Stigma Scale, and Hospital Anxiety and Depression Scale (HADS). Multiple linear regression analyses were used.

RESULTS

The mean EKP-M score was 22.2 (SD: 4.1). By univariate analyses, the EKP-M was related to ESES (r=0.220, p<0.001) and HADS-D (r=-0.154, p<0.001) scores but not to the Stigma Scale or HADS-A. By linear regression analyses, after adjusting for the confounding variables, the higher EKP-M scores were independently related to both higher ESES (p<0.001) and lower HADS-D scores (p<0.05).

CONCLUSION

Korean PWE have a relatively low level of knowledge about their condition. Knowledge about epilepsy is associated with a high level of self-efficacy and less depressive symptoms in affected individuals.

Self-management for people with poorly controlled epilepsy: Participants' views of the UK Self-Management in epILEpsy (SMILE) program

BACKGROUND

Epilepsy is a long-term condition that requires self-management, but currently, there is no well-evaluated epilepsy self-education or self-management intervention in the United Kingdom (UK).

AIM

The aim of this study was to examine the views and experiences of the first participants of the Self-Management in epILEpsy UK (SMILE UK) program to assist the development of a full trial.

METHOD

In-depth semistructured interviews and group discussions were conducted with 10 people with poorly controlled epilepsy to explore their views and experiences of the self-management program. Interviews were audio-recorded, transcribed, and analyzed thematically.

RESULTS

All participants viewed the program positively. Three themes emerged: i) peer support was experienced through knowledge sharing, disclosure of experiences, and exchange of contact details; ii) participants felt better equipped to enter discussions with doctors and other health-care professionals about their condition; and iii) participants reported an improvement in their personal life through increased confidence to live with epilepsy and acceptance of their diagnosis.

CONCLUSION

A brief group self-management intervention increased knowledge and confidence in managing epilepsy.

'Seizure First Aid Training' for people with epilepsy who attend emergency departments, and their family and friends: study protocol for intervention development and a pilot randomised controlled trial

INTRODUCTION

People with chronic epilepsy (PWE) often make costly but clinically unnecessary emergency department (ED) visits. Offering them and their carers a self-management intervention that improves confidence and ability to manage seizures may lead to fewer visits. As no such intervention currently exists, we describe a project to develop and pilot one.

METHODS AND ANALYSIS

To develop the intervention, an existing group-based seizure management course that has been offered by the Epilepsy Society within the voluntary sector to a broader audience will be adapted. Feedback from PWE, carers and representatives from the main groups caring for PWE will help refine the course so that it addresses the needs of ED attendees. Its behaviour change potential will also be optimised. A pilot randomised controlled trial will then be completed. 80 PWE aged ≥16 who have visited the ED in the prior 12 months on ≥2 occasions, along with one of their family members or friends, will be recruited from three NHS EDs. Dyads will be randomised to receive the intervention or treatment as usual alone. The proposed primary outcome is ED use in the 12 months following randomisation. For the pilot, this will be measured using routine hospital data. Secondary outcomes will be measured by patients and carers completing questionnaires 3, 6 and 12 months postrandomisation. Rates of recruitment, retention and unblinding will be calculated, along with the ED event rate in the control group and an estimate of the intervention's effect on the outcome measures.

ETHICS AND DISSEMINATION

Ethical approval: NRES Committee North West-Liverpool East (Reference number 15/NW/0225). The project's findings will provide robust evidence on the acceptability of seizure management training and on the optimal design of a future definitive trial. The findings will be published in peer-reviewed journals and presented at conferences.

A review of 'medical' knowledge of epilepsy amongst isiZulu-speaking patients at a regional hospital in KwaZulu-Natal

BACKGROUND

Epilepsy is a common disorder in South Africa and the literature indicates that many patients do not access treatment. The reasons are complex and include a poor knowledge about causes, symptoms, diagnosis and treatment (medical knowledge). This study aimed to assess the medical knowledge of isiZulu-speaking people with epilepsy (PWE) who attend a combination regional and district hospital in the eThekwini district in KwaZulu-Natal Province.

METHOD

This was a prospective, cross-sectional, descriptive study. Data were collected using a validated data collection tool for assessing the medical knowledge of PWE and analysed descriptively.

RESULTS

The questionnaires were completed by 199 PWE, with the general level of schooling being low and half being unemployed. Knowledge around causes, symptoms, diagnosis and treatments was good, but there were significant gaps in knowledge that may affect morbidity and mortality.

DISCUSSION

The findings will serve as a useful guide to develop both preventive and educational interventions to enhance knowledge around the causes and treatment of epilepsy in this population. It is important that such interventions also consider family and healthcare providers.

CONCLUSION

There were considerable gaps in the medical knowledge of isiZulu-speaking PWE's, indicating the need for an educational intervention to improve their understanding of epilepsy. Further research is needed-using a range of tools to ensure that the data is reliable and valid-if the results are to be generalisable to the rest of the province and South Africa.

People with epilepsy lack knowledge about their disease

For people with epilepsy, knowledge of their disease is an important factor in optimizing the control of their seizures. Better-informed patients can more easily participate in the treatment process, reducing disease-related anxiety and coping better with stigma. This study was developed in a Lithuanian tertiary epilepsy center to assess knowledge of disease among people with epilepsy, to estimate differences in disease knowledge between patient groups, and to evaluate how epilepsy influences patients' daily lives. We asked patients to complete a questionnaire and collected information from outpatient cards on epilepsy etiology, type of seizures, findings of diagnostic tests, and information about patients' antiepileptic drugs. Our results showed that people with epilepsy have poor knowledge about their disease: almost half of the patients did not identify the cause of their illness or their type of seizures; most did not know the results of their EEG and neuroimaging studies. Patients also lacked general knowledge about their disease and implications for lifestyle. However, cognitive deficits were not assessed in this study, and this may have affected the answers where patients were required to recall and name their drugs or the dosage of medication. Almost half of them believed that epilepsy had changed their lives significantly and reported anxiety and constant fear of seizures. Patients were also afraid to have because of the possibility they would also have epilepsy. There is clearly a great need for improved educational intervention for people with epilepsy.

The social context and the need of information from patients with epilepsy: evaluating a tertiary referral service

Objective Characterize the social profile and the need of information from patients with refractory epilepsy. Method A semi-structured questionnaire was applied to 103 patients to investigate sociodemographic aspects, pharmacotherapy and any doubts about epilepsy. Results Patients were highly dependent on having a free and accessible supply of antiepileptic drugs. Sixty-eight percent of the population was unemployed, and 26% confirmed receiving social security benefits due to epilepsy. Twenty-nine percent of the population reached high school. Eighty-five percent of the patients had at least one doubt about epilepsy; treatment and epilepsy aspects in general were the main topics. Conclusion : As observed in developed countries, patients with refractory epilepsy from a developing country also have high rates of unemployment and low educational levels. The results raise a concern about the need of information about epilepsy by patients and their families, urging the necessity to invest in strategies to solve this deficiency in knowledge.

Factors affecting epilepsy treatment outcomes in Nigeria

OBJECTIVES

Epilepsy is a complex chronic illness with variable treatment outcomes determined by factors specific to each affected person. We investigated prognostic factors for epileptic seizure outcome after 2 years of anti-epileptic drug (AED) monotherapy.

MATERIALS AND METHODS

Two hundred and thirty-four AED naïve epilepsy patients were started on AED monotherapy and monitored for 2 years for seizure control. Patients on AED polytherapy were excluded. Prognostic factors investigated were socio-demographics characteristics, age of onset of epilepsy, etiology and precipitants of seizures, presenting seizure types, duration of epilepsy before initiation of AED, family support for treatment, compliance to AED, and clinic attendance.

RESULTS

Patients were 160 (68.4%) males and 74 (31.6%) females, with mean ages of 26.2 ± 10.4 and 30.7 ± 16.0 years, respectively. Mean age of onset of epilepsy was 19.0 ± 15.0 years. None of the patients was treated with AED for first seizures, although 75% received traditional and spiritual therapy. Majority were single and of low socioeconomic background, and treatment was funded mainly by parents/guardians. About 88% presented with partial seizures, and carbamazepine was the commonest AED used followed by phenytoin sodium. At the end of 2 years of AED, 147 (63%) achieved complete seizure control, and significant prognostic factors were female sex, age older than 20 years at presentation, secondary and tertiary education attainment, being employed, family support, regular clinic attendance, AED compliance, and generalized epilepsy.

CONCLUSIONS

Patients with epilepsy are more likely to achieve complete seizure control when they are older, educated, and employed or supported by family members to buy their AEDs and attend clinics regularly.

Self-Management education for adults with poorly controlled epILEpsy (SMILE (UK)): a randomised controlled trial protocol

BACKGROUND

Teaching people with epilepsy to identify and manage seizure triggers, implement strategies to remember to take antiepileptic drugs, implement precautions to minimize risks during seizures, tell others what to do during a seizure and learn what to do during recovery may lead to better self-management. No teaching programme exists for adults with epilepsy in the United Kingdom although a number of surveys have shown patients want more information.

METHODS/DESIGN

This is a multicentre, pragmatic, parallel group randomised controlled trial to evaluate the effectiveness and cost-effectiveness of a two-day Self-Management education for epILEpsy (SMILE (UK)), which was originally developed in Germany (MOSES).Four hundred and twenty eight adult patients who attended specialist epilepsy outpatient clinics at 15 NHS participating sites in the previous 12 months, and who fulfil other eligibility criteria will be randomised to receive the intervention (SMILE (UK) course with treatment as usual- TAU) or to have TAU only (control). The primary outcome is the effect on patient reported quality of life (QoL). Secondary outcomes are seizure frequency and psychological distress (anxiety and depression), perceived impact of epilepsy, adherence to medication, management of adverse effects from medication, and improved self-efficacy in management (mastery/control) of epilepsy.Within the trial there will be a nested qualitative study to explore users' views of the intervention, including barriers to participation and the perceived benefits of the intervention. The cost-effectiveness of the intervention will also be assessed.

DISCUSSION

This study will provide quantitative and qualitative evidence of the impact of a structured self management programme on quality of life and other aspects of clinical and cost effectiveness in adults with poorly controlled epilepsy.

Can an epilepsy nurse specialist-led self-management intervention reduce attendance at emergency departments and promote well-being for people with severe epilepsy? A non-randomised trial with a nested qualitative phase

Objectives

To (1) describe the characteristics and service use of people with established epilepsy (PWE) who attend the emergency department (ED); (2) evaluate the economic impact of PWE who attend the ED; (3) determine the effectiveness and cost-effectiveness of an epilepsy nurse specialist (ENS)-led self-management intervention plus treatment as usual (TAU) compared with TAU alone in reducing ED use and promoting well-being; (4) describe patients' views of the intervention; and (5) explore their reasons for attending the ED.

Design

Non-randomised trial with nested qualitative study.

Setting

The EDs of three inner London hospitals. The EDs each offer similar services and support a similar local population, which made a comparison of patient outcomes reasonable.

Participants

Adults diagnosed with epilepsy for ≥ 1 year were prospectively identified from the EDs by presenting symptom/discharge diagnosis. We recruited 85 of 315 patients with 44 forming the intervention group and 41 the comparison group.

Intervention

Intervention participants were offered two one-to-one outpatient sessions delivered by an ENS who aimed to optimise self-management skills and knowledge of appropriate emergency service use. The first session lasted for 45–60 minutes and the second for 30 minutes.

Main outcome measures

The primary outcome was the number of ED visits that participants reported making over the 6 months preceding the 12-month follow-up. Secondary outcomes were visits reported at the 6-month follow-up and scores on psychosocial measures.

Results

In the year preceding recruitment, the 85 participants together made 270 ED visits. The frequency of their visits was positively skewed, with 61% having attended multiple times. The mean number of visits per participant was 3.1 [standard deviation (SD) 3.6] and the median was two (interquartile range 1–4). Mean patient service cost was £2355 (SD £2455). Compared with findings in the general epilepsy population, participants experienced more seizures and had greater anxiety, lower epilepsy knowledge and greater perceived stigma. Their outpatient care was, however, consistent with National Institute for Health and Clinical Excellence recommendations. In total, 81% of participants were retained at the 6- and 12-month follow-ups, and 80% of participants offered the intervention attended. Using intention-to-treat analyses, including those adjusted for baseline differences, we found no significant effect of the intervention on ED use at the 6-month follow-up [adjusted incidence rate ratio (IRR) 1.75, 95% confidence interval (CI) 0.93 to 3.28] or the 12-month follow-up (adjusted IRR 1.92, 95% CI 0.68 to 5.41), nor on any psychosocial outcomes. Because they spent less time as inpatients, however, the average service cost of intervention participants over follow-up was less than that of TAU participants (adjusted difference £558, 95% CI –£2409 to £648). Lower confidence in managing epilepsy and more felt stigma at baseline best predicted more ED visits over follow-up. Interviews revealed that patients generally attended because they had no family, friend or colleague nearby who had the confidence to manage a seizure. Most participants receiving the intervention valued it, including being given information on epilepsy and an opportunity to talk about their feelings. Those reporting most ED use at baseline perceived the most benefit.

Conclusions

At baseline, > 60% of participants who had attended an ED in the previous year had reattended in the same year. In total, 50% of their health service costs were accounted for by ED use and admissions. Low confidence in their ability to manage their epilepsy and a greater sense of stigma predicted frequent attendance. The intervention did not lead to a reduction in ED use but did not cost more, partly because those receiving the intervention had shorter average hospital stays. The most common reason reported by PWE for attending an ED was the lack of someone nearby with sufficient experience of managing a seizure. Those who attended an ED frequently and received the intervention were more likely to report that the intervention helped them. Our findings on predictors of ED use clarify what causes ED use and suggest that future interventions might focus more on patients' perceptions of stigma and on their confidence in managing epilepsy. If addressed, ED visits might be reduced and efficiency savings generated.

What is important in rehabilitation for persons with epilepsy? Experiences from focus group interviews with patients and staff

This study aimed to identify the issues experienced as essential in rehabilitation for persons with epilepsy. Six focus group interviews were conducted, five groups with patients that had completed comprehensive rehabilitation for persons with epilepsy, in a day-care setting, at the Neurological Rehabilitation Clinic at Stora Sköndal Hospital, between 2006 and 2009 (total n=17) and one group with staff members (n=5). Using content analysis, two themes emerged: life with epilepsy and rehabilitation experiences. The result emphasizes that rehabilitation for persons with epilepsy should be designed individually, in structure and in content. Encounters between patients were important, as well as the team's attitude in meeting with the patients. Therapeutic working alliance is essential between patients and staff for creating an individual rehabilitation.

Characteristics of patients with epilepsy who use a website providing healthcare information about epilepsy in South Korea

We studied characteristics of epilepsy patients who use 'Epilia', a healthcare website for epilepsy patients, and the impact of 'Epilia' on patient satisfaction and attitude about epilepsy. A total of 153 epilepsy patients from 'Epilia' (online group) and 367 patients from epilepsy clinics (offline group) were recruited. A survey was done to investigate their socio-demographic, epilepsy-related, and psychological characteristics, as well as attitude alterations after beginning to use 'Epilia'. Factors affecting attitude were also identified in the online group. Online group had more severe and more frequent seizures, more adverse effects, more anxiety and depression, and worse quality of life than offline group. Online group patients who are more satisfied, who take two or more antiepileptic drugs, who visit to 'Epilia' more and longer had a greater positive attitude change than those without these characteristics. A healthcare website can contribute to self-management by providing useful information and education for epilepsy patients.

The psychoeducational program for children with epilepsy and their parents (FAMOSES): results of a controlled pilot study and a survey of parent satisfaction over a five-year period

Feasibility of the educational program FAMOSES (modular service package epilepsy for families) was evaluated in a controlled pilot study. Parents of children with epilepsy from epilepsy centers in Germany were allocated to either educational group (treatment group, n=55) or waiting-list group (control group, n=48). Questionnaires included epilepsy-specific scales (knowledge, coping, adaptation, anxiety, rules and limitations, seizure management, impact of epilepsy). Multivariate analysis of variance with repeated measurements indicated significant improvements in the treatment group compared to the control group (time×group interaction: p<0.01). Univariate analyses (ANOVA) confirmed improvements in knowledge (p<0.001), adaptation (p<0.01), epilepsy-related anxiety (p<0.05), and seizure management (p<0.05). Surveillance as well as seizure frequency (p<0.05) of children whose parents participated in the treatment group was reduced (p<0.05). Furthermore, parents' satisfaction with the content and interactive didactic format of the program was assessed in a survey with 852 parents over a five-year period. This survey showed an improvement over the course of time (p<0.05). Feasibility and need for the educational program were confirmed.

Personalised epilepsy education intervention for adolescents and impact on knowledge acquisition and psychosocial function

AIM

Patients frequently have poor knowledge of epilepsy, and this is associated with low self-esteem in adolescence. There is a paucity of data determining whether education alone can improve psychosocial outcome. The study investigated whether an educational intervention in adolescence: 1 Increased understanding of epilepsy syndrome and general epilepsy knowledge. 2 Improved self-esteem, seizure self-efficacy and attitudes towards epilepsy.

METHODS

In session 1, adolescents were educated about their epilepsy syndrome in a one-on-one session, producing a personalised epilepsy medical record. In session 2, the impact of epilepsy on life-style was discussed. Pre- and post-intervention measures of knowledge, self-esteem, seizure self-efficacy and attitudes towards epilepsy were completed using validated scales. Focus groups explored the intervention's value.

RESULTS

Thirty adolescents with epilepsy participated (female: 24, male: 6; median age: 16 years; partial symptomatic epilepsy: 15, generalised idiopathic epilepsy: 15). Self-knowledge of syndrome (P < 0.0001), general knowledge of epilepsy (P < 0.0001), attitudes towards epilepsy (P= 0.008) and seizure self-efficacy (P= 0.049) improved. Focus group data indicated that sessions were enjoyable and valuable, and the medical record was helpful.

CONCLUSIONS

The intervention significantly improved self-knowledge and general knowledge of epilepsy, attitudes towards epilepsy and seizure self-efficacy. This is the first study to demonstrate a positive impact on psychosocial outcomes following an educational intervention without a psychological component. The model has widespread application.

Patients' knowledge about their disorder: perspective of patients with epilepsy in a tertiary health facility in southwestern Nigeria

OBJECTIVE

Previous studies have shown that patients with epilepsy do not have adequate knowledge about their disorder, suggesting that patient education is a vital part of comprehensive care for epilepsy. The goal of this study was to evaluate what Nigerian patients with epilepsy know about their disorder.

METHODS

Forty-six patients with EEG- and clinically confirmed epilepsy participated in the study. The patients completed the Epilepsy Patients Knowledge Questionnaire. The questionnaire includes topics related to etiology of epilepsy, safety, compliance, legal issues of driving, and employment. The questionnaire scores were correlated with demographic variables, duration of epilepsy, and level of education of the patients.

RESULTS

The mean age of the respondents was 26.78 ± 9.27 years; there were 27 males and 19 females. The mean duration of epilepsy in the group was 7.6 ± 7.5 years. The mean rates of correct responses to the issues of safety and compliance were 31.6 and 76.8%, respectively. The mean scores on legal issues of driving and employment were 45.7 and 42.4%, respectively. The lowest score (10.9%) was on the etiology of epilepsy.

CONCLUSION

Nigerian patients with epilepsy lack adequate knowledge about their disorder, and there is a need for improved educational intervention in these patients.

Evaluation of WebEase: an epilepsy self-management Web site

People with epilepsy have various education needs and must adopt many self-management behaviors in order to control their condition. This study evaluates WebEase, an Internet-based, theory-driven, self-management program for adults with epilepsy. Thirty-five participants took part in a 6-week pilot implementation of WebEase. The main components of WebEase are My Log, a behavioral journal, and the Medication, Stress and Sleep Modules, which provide tailored information and feedback designed to prompt participants to assess their status with self-management behaviors, think about their behaviors and make a goal. In this article, we discuss the results of the feasibility, acceptability and usability assessments and the behavioral outcomes. The process results indicate that theoretical components that served as the program framework were successfully integrated into the program and that participants viewed WebEase as relevant, acceptable and easy to use. Additionally, participants showed some improvement in epilepsy self-management, adherence, sleep quality, self-efficacy and social support following the program. The initial results are encouraging and continued development of WebEase has the potential to facilitate education and self-management strategies among people with epilepsy.

Do knowledge of, perception of, and attitudes toward epilepsy affect the quality of life of Turkish children with epilepsy and their parents?

The main goal of this study was to evaluate knowledge of, perceptions of, and attitudes toward epilepsy and then to correlate knowledge with quality of life and stigmatization of children with epilepsy and their families. Specific questionnaires were administered to children aged 8 to 17 with epilepsy (n=220) and their parents (n=313). Poor school performance, less social support, less self-esteem, higher anxiety, greater stigmatization, and more depressive symptoms were documented in children who were less knowledgeable (P<0.05). Parents were found to be more knowledgeable about the antiepileptic drugs used, understanding both the effects and the side effects of the medications (P<0.05). Family activities were less restricted if they were more knowledgeable and these parents reported worrying less about their children (P<0.05). Knowledge about epilepsy is associated with less perceived stigmatization and social isolation, as well as fewer depressive symptoms and misperceptions.

Patient, caregiver, and health care practitioner knowledge of, beliefs about, and attitudes toward epilepsy

The medical literature related to knowledge of, beliefs about, and attitudes toward epilepsy was reviewed from the perspective of patients, caregivers, and health care providers. The literature points to a desire for enhanced epilepsy education by patients and caregivers; however, these needs have not been met by primary or specialty care. Surveys of general practitioners (GPs) point to limitations in knowledge and negative attitudes. GPs view their role in epilepsy care as primarily educational and tend to acknowledge their limitations by referring difficult cases. Ongoing education for GPs is important, as is an improved partnership in defining roles for care and education. Health care professionals specialized in epilepsy care acknowledge their own set of barriers to optimal care. Epilepsy education programs have been able to improve knowledge; however, long-term improvements in behavioral outcomes or quality of life are less documented. Suggestions for improvements are provided.

Use of computers and the Internet for health information by patients with epilepsy

The purpose of this study was to describe computer and Internet use among an online group and a clinic-based group of people with epilepsy. Greater than 95% of the online group and 60% of the clinic group have access to computers and the Internet. More than 99% of the online group and 57% of the clinic group used the Internet to find health information. A majority of people reported being likely to employ an Internet-based self-management program to control their epilepsy. About 43% reported searching for general information on epilepsy, 30% for medication, 23% for specific types of epilepsy, and 20% for treatment. This study found that people with epilepsy have access to computers and the Internet, desire epilepsy-specific information, and are receptive to online health information on how to manage their epilepsy.

First aid for seizures: the importance of education and appropriate response

In most circumstances, first aid for seizures aims to protect the individual from harm during a seizure. Many people harbor misconceptions about or simply do not know how to respond to a seizure. Guidelines for seizure first aid from the Epilepsy Foundation are readily available and widely distributed, yet data from surveys and studies illustrate a deep unmet need in seizure first aid education. Lack of knowledge increases the potential for inappropriate or inadequate responses by parents, teachers, coworkers, and the public at large to repetitive or prolonged seizures, and the associated discomfort about how to provide first aid also can contribute to the general stigma associated with epilepsy. Clinicians play a key role in educating patients, parents, caregivers, and the community about how to respond to an individual who is having a seizure. This article reviews the data regarding seizure first aid knowledge among the various groups that may be called on to respond to a repetitive or prolonged seizure, highlights important goals of seizure first aid (including the prevention of status epilepticus) that should be relayed to these groups, and discusses the positive impact of seizure first aid education.

Evidence-based standards of care for adults with epilepsy—a literature review

Epilepsy is the most common serious chronic neurological condition. All patients with epilepsy regardless of location should receive the highest quality of services that can be provided. In order to do this current service provision has to be reviewed and bench marked against ideal standards of service provision that cover a comprehensive range of services to meet all patient needs. By critically reviewing the relevant literature, criteria were developed for an ideal epilepsy service. The literature review generated evidence-based ideal standards for the following service areas: - The role of primary care and the interface with secondary care in the management of epilepsy; - The role of Accident and Emergency (A and E) departments in the care of epilepsy; - Epilepsy clinics; - Specialist epilepsy nurses for treating epilepsy; - The role of the general practitioner (GP) specialist; - Services for adult epileptics with learning disabilities; - Services for complex epilepsy; and - User views. Although many of the recommendations are based on evidence of a lower grade, the direction of the existing evidence obtained from several sources, suggested similar standards for an epilepsy service. The effectiveness and value of epilepsy services, particularly in relation to the changes recommended above, must be further researched.

Medication education for patients with epilepsy in Taiwan

The aim of this study is to evaluate the medication knowledge achieved by conventional verbal education and the influence of drug information leaflets in patients with epilepsy. Drug compliance and sources of information of the patients were also examined. Fifty-one adults in an epilepsy outpatient clinic participated this survey. These patients were asked to complete a questionnaire and to specify sources of drug information. Serum drug levels were checked and compared with the self-reported compliance. Then, drug information leaflets were given to patients. In the next follow-up visit, patients were asked to fill out the same questionnaire again. In the baseline assessment, 36 patients (70.6%) could accurately list their medications. However, half of patients were not knowledgeable about side effects and did not keep a seizure diary. After provision of drug leaflets, the epilepsy medication assessment score increased from 3.9 +/- 1.9 to 5.1 +/- 1.7 (P<0.001). In addition, patients reported being compliant most of the time and this matched drug levels. On average, each patient had 2.8 sources of information and 5 patients used Internet as a tool. Despite achieving good compliance, conventional verbal education did not sufficiently cover drug-related issues. Providing patients with written information apparently increase their medication knowledge and probably enhance seizure control.

Patient's perspective on epilepsy: self-knowledge among Omanis

Improving patients' knowledge has been suggested to improve their symptoms and prognosis. Very little is known about epileptic patient's knowledge of their illness in cross-cultural settings. This pilot study investigated what Omani patients know about their disorder. Patients attending a tertiary hospital completed a structured knowledge questionnaire to elicit information pertaining to aetiology, safety, compliance with medication regimes, legal and employment issues concerning epilepsy.Although correctly endorsing issues related to their medication, this cross-cultural sample was found to have limited knowledge about their condition. In particular, most patients were unable to give accurate indications of epilepsy, neither were they able to give correct responses to questions pertaining to safety and compliance. There is a need for improving patient's knowledge. As with other chronic disorders, people with epilepsy in Oman should receive systematic health education about how to manage the condition most effectively.

Cross-cultural differences in levels of knowledge about epilepsy

PURPOSE

To study how much people with epilepsy in Europe know and understand about their condition and how this might affect their lives.

METHODS

Clinical, demographic, psychosocial details and information assessing knowledge were collected by using self-completion questionnaires mailed to members of epilepsy support groups.

RESULTS

Data were collected from 6,156 people with epilepsy from ten European countries. There were significant between-country differences in all variables considered. Overall levels of knowledge were acceptable when measured by the epilepsy knowledge questionnaire (EKQ, medical items). However, there were some gaps in knowledge, particularly in issues relating to medication and cause of epilepsy.

CONCLUSIONS

This is the largest study of its kind to date. Results clearly highlighted that levels of knowledge differed significantly between countries. Overall, people with epilepsy are reasonably well informed about epilepsy, although some gaps in knowledge were evident.

People with epilepsy: what do they know and understand, and how does this contribute to their perceived level of stigma?

Understanding the factors that contribute to the process of stigmatization of those with epilepsy may be an important element in the management of this condition. This study was designed to determine the contribution of clinical, demographic, and psychosocial variables to the stigma of epilepsy in adults. More than 6000 adults from 10 European countries were surveyed. Almost half of respondents reported that they had difficulty accepting their illness, and 17% felt stigmatized by it. A number of factors were predictive of stigma, including seizure frequency, knowledge of epilepsy, duration of epilepsy, and seizure type. The relative contributions of these factors varied depending on the country of origin of those surveyed. Further research is warranted to determine societal influences on the process of stigmatization.

The efficacy of an educational treatment program for patients with epilepsy (MOSES): results of a controlled, randomized study. Modular Service Package Epilepsy

PURPOSE

To evaluate the efficacy of the educational program MOSES (Modular Service Package Epilepsy). It was developed to improve patients' knowledge and understanding about their epilepsy, its treatment, and psychosocial consequences. The program intends to improve patients' coping with the disease, to strengthen self-esteem, and to support patients to become experts in managing their epilepsy.

METHODS

A controlled, randomized study design was used to examine the efficacy of MOSES. Patients from 22 epilepsy centers in Germany, Austria, and Switzerland were randomly allocated to either MOSES group (treatment group) or waiting-list group (control group). The 242 patients were aged from 16 to 80 years. The MOSES group (n = 113) completed the questionnaires immediately before the educational course (T1) and 6 months later (T2), and the control group (n = 129), 6 months before (T1) and immediately before (T2) the course. The questionnaires included generic instruments (SF-36, Rosenberg self-esteem Scale, von Zerssen Depression Scale), and epilepsy-specific scales (Restrictions in Daily Life, Epilepsy-Related Fears, Coping with Epilepsy and Adaptation). Depression was used as a moderator variable. Seizure frequency and satisfaction with therapy also were assessed. Multivariate analysis of variance (MANOVA) with repeated measurements and univariate analyses of variance were performed.

RESULTS

The MANOVA showed that participants of the educational program improved significantly. Univariate analyses revealed improvements in knowledge (p < 0.001) and coping with epilepsy (p = 0.004), whereas important effects of MOSES on other epilepsy-specific measures and on generic questionnaires (SF-36, self-esteem) were not found. Participants of the MOSES program also improved in seizure outcome (p = 0.041) and became more satisfied with the therapy [better tolerability of antiepileptic drug (AED) therapy, fewer side effects; p = 0.014]. In addition, participants expressed being highly satisfied with the program.

CONCLUSIONS

The study clearly indicates the need for patient education. Even patients with a long history of epilepsy and with additional handicaps or diseases benefitted from the MOSES program.

What do patients want and get from a primary care epilepsy specialist nurse service?

PURPOSE

To assess what patients want and get from a primary care epilepsy specialist nurse service, and whether this matches their expectations and self-defined needs.

METHODS

A qualitative study nested within a controlled trial to evaluate the effectiveness of a primary care epilepsy specialist nurse service in Bristol, UK. Twelve patients who had had at least one seizure in the previous year were purposely selected from the trial population for an in-depth interview. Interviews were audiotape recorded and transcribed verbatim. Transcribed text was methodically coded and themes were identified using the method of constant comparison.

RESULTS

Not all informants wanted to see the epilepsy nurse as they felt their epilepsy was well controlled and thus they did not see the need for care or attention. Those that chose to use the nurse service did so as they wanted information on epilepsy or better control of their seizures. The epilepsy nurse was able to provide them with the information they wanted but was not able to improve their seizure control. Informants felt able to communicate effectively with the nurse and they valued the information and advice received. They were unable to get this kind of communication and empathy from other clinicians. Informants generally praised the nurse service but were aware that it was unlikely to improve the control of their seizures. Most accepted this.

CONCLUSIONS

Effective communication with clinicians is as much, if not more of a priority for patients with epilepsy, than is controlling the clinical manifestations of their condition.

A systematic overview--a decade of research'. The information and counselling needs of people with epilepsy

This paper explores the background to epilepsy in terms of medical impact and psychosocial effects. The argument that information and counselling may be central to the person with epilepsy is explored. The evidence from primary research published between 1990 and 2000 investigating the information and counselling needs of people with epilepsy is appraised and synthesized. This paper seeks to answer the following questions: What are the information and counselling needs of people with epilepsy? What are the preferred formats, timing and delivery of information and counselling? What are the outcomes of information giving and counselling for people with epilepsy? The review suggests that there are unmet needs for personal and general information about epilepsy which may include individual or group education and counselling. Information related to gaining control for people with epilepsy and targeted public education may contribute to improved quality of life for people with epilepsy. Information is required which is individually relevant and could be delivered in small groups or as part of an individual counselling service. Specialist epilepsy clinics and specialist nurses can improve patient knowledge and communication and provide an effective and high quality service for people with epilepsy.

Psychosocial aspects of epilepsy in Oman: attitude of health personnel

PURPOSE

To assess with a questionnaire the awareness and attitudes of the doctors in Oman toward epilepsy. Attitudes of society toward epilepsy have a wide-ranging influence, affecting issues as diverse as compliance with treatment and doctor--patient communication. Recent studies in both developing and developed countries suggest that within the medical profession, there is a lack of knowledge and negative attitudes toward people with epilepsy (PWE). There are no equivalent studies for Oman or the Arab world.

METHODS

The questionnaire included queries on the backgrounds of the physicians, including their training and qualifications, the main sources of their knowledge of epilepsy, as well as their perceptions of the attributes and care requirements of PWE.

RESULTS

Sixty-two percent (n=121) of those questioned, who were medical personnel working in different regions of Oman, responded. The results suggest that, despite coming from diverse cultural backgrounds and nationalities, the practicing doctors in Oman gained knowledge of epilepsy much earlier than did their counterparts in developed countries. The majority of the respondents thought that PWE have more propensities toward dysfunctional personality and behavioral characteristics than do "normal" people. On questions relating to public image, our respondents opined that, although the general public is negative toward PWE, the realities regarding PWE should be publicized because PWE are capable of having a normal family life and being an integral part of society.

CONCLUSIONS

In spite of having an earlier exposure to seizures and sympathetic acceptance of PWE, negative views still persist on matters related to cognitive and behavior domains. It is concluded that a developing country such as Oman must inculcate more realistic perceptions and attitudes among their doctors toward PWE.

The difference in perceptions of educational need between epilepsy patients and medical personnel

PURPOSE

This study was undertaken to determine what patients with epilepsy need to know about their condition, and to discern what differences exist between patients' perceptions of this need and the medical profession's perception of what patients should know.

METHODS

Seventy-five consecutive patients with epilepsy and 56 medical personnel (residents and nurses) who were working in either Neurology or Neurosurgery Units were studied using a structured questionnaire consisting of 3 subsets with a total of 27 questions.

RESULTS

Using a Likert scale, epilepsy patients gave high priority to their need for more information about "how epilepsy is diagnosed," "the structure of the brain" (p < 0.05, p < 0.01, respectively), and "the diet that might prevent the attack" (p < 0.05) than did medical personnel. Our study also revealed that men were more concerned with questions regarding smoking and drinking than were women (p < 0.05, respectively), whereas married patients gave higher scores in the category of employment (p < 0.01) and contraception/pregnancy (p < 0.05) than did unmarried patients. The patients with one or more seizures per month rated higher scores on questions concerning the first aid at the time of attack and dosage of antiepileptic drugs (AEDs; p < 0.05, respectively) than did the patients with fewer than one seizure per month. The patients taking poly-AED treatment gave higher scores on six items related to AED therapy than did those receiving monotherapy. No significant differences were found with regard to the length of time patients had the condition, nor to educational level or current employment status.

CONCLUSIONS

An educational program for epilepsy patients should be developed on the basis of understanding that there are differences in perspectives among patients with different sociocultural contexts as well as between patients and medical personnel.

High and low perceived self-control of epileptic seizures

PURPOSE

To define behaviours and to identify psychological, demographic, and epilepsy-related variables associated with high as opposed to low perceived self-control of seizures.

METHOD

In a semistructured interview, 100 adults with intractable seizures were asked about their seizure precipitants and attempts at self-control of seizures. They also completed four psychological questionnaires. Latent Class Analysis was used to analyse the interview data to create two groups, High Controllers and Low Controllers, who were then compared on demographic, epilepsy, and psychological characteristics.

RESULTS

Being able to identify and seeking out low-risk-for-seizure situations, avoiding high-risk-for-seizure situations, and making attempts at seizure inhibition were seizure behaviours that discriminated High from Low Controllers. The general probability of being a High Controller was greater than that of being a Low Controller. Perceived high self-control of seizures was associated with low chance-health locus of control. For Low Controllers, current age, age at onset of seizures, and duration of epilepsy history were related to psychological variables. A significantly higher proportion of the Low Controllers than High Controllers were women.

CONCLUSIONS

Many people with intractable seizures do not accept their epilepsy as a condition over which they have no control. Perceived self-control of seizures, however, involves a complex interaction between epilepsy and psychological factors, with health locus of control an apparently important discriminator between High and Low Controllers.

Continuing professional development: medico-legal aspects of epilepsy

Generally protection against possible litigation and good clinical practice go hand in hand. Situations in which the law has special relevance for people with epilepsy, those who work with them, and their clinicians are reviewed with special reference to the topics of driving, employment, duties of social carers, the clinician's everyday role, the responsibilities of researchers and epilepsy and the criminal law. What constitutes professional negligence is discussed, with special reference to the United Kingdom. Clinicians are advised to think clearly, write clearly, communicate clearly and have a good relationship with their patients.

Compliance with health regimens of adolescents with epilepsy

The purpose of this paper was to describe the compliance of adolescents with epilepsy and some factors connected to it. Altogether 300 individuals with epilepsy aged 13-17 years were randomly selected from the Finnish Social Insurance Institution's register. Every fifth person on the list was included in the sample. Seventy-seven per cent (n= 232) of the selected adolescents with epilepsy returned a questionnaire sent to them relating to compliance. The data were analysed using the SPSS software. Twenty-two per cent of the adolescents with epilepsy felt that they complied fully with their suggested health regimens, while 44% placed themselves in the category of "satisfactory compliance", and the remaining 34% reported poor compliance. Compliance with their recommended life-style was poorest, while the highest degree of compliance was recorded for medication. Background variables, such as the duration of the disease, exercise, smoking, alcohol-intake and the number of seizures, were statistically significantly related to compliance (P< 0.001). Good motivation, a strong sense of normality, experience of results, subjective outcome, energy and will-power, support from parents, physicians and nurses, and a positive attitude towards to the disease and its treatment, no threat to social and emotional well-being and no fears of complications and no fear of seizures explained good compliance (P< 0.001).

An assessment of epilepsy patients' knowledge of their disorder

PURPOSE

Patient education is an effective component of comprehensive care. Studies assessing patient's knowledge of their epilepsy are scarce. We report the first objective study evaluating knowledge of epilepsy patients referred to an American tertiary care center.

METHODS

Two hundred twenty epilepsy patients referred to an epilepsy center completed a knowledge questionnaire. The questionnaire included topics related to safety, compliance, and legal issues of driving and employment. Questionnaire scores were correlated with demographics, number of years with epilepsy, and educational background.

RESULTS

Of 220 patients, 175 were included in study analysis. Thirteen percent (n = 28) were excluded because of the diagnosis of nonepileptic seizures, and 8% (n = 17) were excluded because of having a diagnosis other than epilepsy. The average age and number of years with epilepsy was 34.7 +/- 13 and 14. 4 +/- 13.1, respectively. Neither age (r = 0.20, p </=0.01), number of years with epilepsy (r = 0.09, p = 0.2), nor years of education (r = 0.34, p </=0.01) correlated with questionnaire scores. Thirty percent believed that epilepsy is a mental disorder or contagious. Forty-one percent believed it is appropriate to place an object in a patient's mouth during a seizure to prevent injury. Two of the lowest scores, 13.6% and 47.5%, pertained to the legal issues of driving and employment, respectively.

CONCLUSIONS

Patients with epilepsy are not knowledgeable about their disorder. This is true regardless of age, educational background, or number of years with epilepsy. There is a need for educational intervention in this population, particularly related to injury prevention and the legalities of driving and employment.

Improving the epilepsy service: the role of the specialist nurse

There is currently a wide variation in the level of service provided for patients with epilepsy across the UK. Evidence is becoming available to suggest that improvements in local service provision may be achieved through the intervention of a specialist nurse. Using practical examples, this article explores the roles of the epilepsy specialist nurse, and examines how they may benefit patients and improve services. Functions such as liaison, patient assessment and management, counselling, provision of information, education, and audit are considered. It is hoped that the improved co-ordination and management of epilepsy services, that is achieved through specialist nurse intervention, will lead to improved patient outcomes and increased cost-effectiveness.

Patients' understanding of and adjustment to epilepsy: interim findings from a European survey

The purpose of the study was to discover how much European patients with epilepsy and their carers understand about epilepsy. This article reports the interim results for the first four European countries recruited to the study and includes data collected from 1,920 people with epilepsy and 2,136 carers. Clinical and demographic details and data on understanding of epilepsy were collected using self-completed questionnaires mailed to members of epilepsy support groups. There were no significant differences between people with epilepsy and carers for scores on the Epilepsy Knowledge Questionnaire, although people with epilepsy were more likely to score in the higher ranges. Higher scorers on the questionnaire were more likely to be better educated, to have lower scores on the impact of epilepsy scales, to have higher scores on the adjustment to epilepsy scale, and were less likely to report feeling stigmatized. The study confirms the findings of previous studies that people with epilepsy are reasonably well informed, although some gaps in their knowledge were evident. A comparison of country differences will be made and multivariate statistical analysis will allow a better understanding of the contribution of knowledge to people's overall adjustment to their condition.
