The assessment and treatment of concerns and anxiety in patients undergoing presurgical monitoring for epilepsy

Evidence based noninvasive presurgical evaluation for patients with drug resistant epilepsies

PURPOSE OF REVIEW

To review the current practices and evidence for the diagnostic accuracy and the benefits of presurgical evaluation.

RECENT FINDINGS

Preoperative evaluation of patients with drug-resistant focal epilepsies and subsequent epilepsy surgery leads to a significant proportion of seizure-free patients. Even those who are not completely seizure free postoperatively often experience improved quality of life with better social integration. Systematic reviews and meta-analysis on the diagnostic accuracy are available for Video-electroencephalographic (EEG) monitoring, magnetic resonance imaging (MRI), electric and magnetic source imaging, and functional MRI for lateralization of language and memory. There are currently no evidence-based international guidelines for presurgical evaluation and epilepsy surgery.

SUMMARY

Presurgical evaluation is a complex multidisciplinary and multiprofessional clinical pathway. We rely on limited consensus-based recommendations regarding the required staffing or methodological expertise in epilepsy centers.

Length of Stay Does Not Predict Change in Epilepsy Monitoring Unit Comfort Questionnaire Scores

ABSTRACT

BACKGROUND: The epilepsy monitoring unit (EMU) is a clinical setting designed to help diagnose and analyze the nature behind a patient's seizures in a hospitalized unit. Patients admitted to an EMU may experience sleep deprivation, withdrawal of antiepileptic medications, and the use of a continuous electroencephalogram. The purpose of this study was to explore change in patient comfort during an EMU admission. METHODS: The Epilepsy Monitoring Unit Comfort Questionnaire (EMUCQ) was used to evaluate the initial stress level of EMU patients on their date of admission versus their fourth day on the unit. RESULTS: The average EMUCQ score from the admission date was 196.6 (26.28), whereas the mean EMUCQ score on the fourth day was 197.8 (24.79). The P value of .802 and t value of 0.25 indicated that the scores were not statistically significantly different. CONCLUSION: Although some scores indicated there was a large change between baseline and follow-up, these scores could not be readily attributed to the patient's length of stay in the unit. Future studies should examine the role of specific variables hypothesized to impact comfort in the EMU.

Do all patients in the epilepsy monitoring unit experience the same level of comfort? A quantitative exploratory secondary analysis

Aims

To find out which variables may be associated with comfort of patients in an epilepsy monitoring unit.

Design

Exploratory, quantitative study design.

Methods

Data were collected from October 2018 to November 2019 in Austria and Southern Germany. A total of 267 patients of 10 epilepsy centres completed the Epilepsy Monitoring Unit Comfort Questionnaire which is based on Kolcaba's General Comfort Questionnaire. Secondary data analysis were conducted by using descriptive statistics and an exploratory model building approach, including different linear regression models and several sensitivity analyses.

Results

Total comfort scores ranged from 83 to 235 points. Gender, occupation and centre turned out to be possible influential variables. On average, women had a total comfort score 4.69 points higher than men, and retired persons 28.2 points higher than high school students ≥18 years. Comfort scores of younger patients were lower than those of older patients. However, age did not show a statistically significant effect. The same could be observed in marital status and educational levels.

Conclusion

When implementing comfort measures, nurses must be aware of variables which could influence the intervention negatively. Especially, high school students ≥18 years should be supported by epilepsy specialist nurses, in order to reduce uncertainty, anxiety and discomfort. But, since the identified variables account only for a small proportion of the inter‐individual variability in comfort scores, further studies are needed to find out additional relevant aspects and to examine centre‐specific effects more closely.

Impact

Nurses ensure patient comfort during a hospital stay. However, there are variables that may impair the effectiveness of the nursing measures. Our study showed that the experience of comfort was highly individual and could be explained by sociodemographic variables only to a limited extent. Nurses must be aware that additional factors, such as the situation in the individual setting, may be relevant.

Parental experience and decision-making for epilepsy surgery: A systematic review of qualitative and quantitative studies

OBJECTIVE

In selected children with drug-resistant epilepsy (DRE), epilepsy surgery is the most effective treatment option, but unfortunately remains highly underutilized. One of the critical obstacles to pursuing surgical therapy is parents/caregivers' decision against surgery or to delay the surgery until no other treatment option exists. Understanding caregiver decision-making around epilepsy surgery can improve patient/caregiver experience and satisfaction while facilitating appropriate decision-making that optimizes clinical outcomes. The current review systematically explores the existing evidence on caregiver experience and the decision-making process toward epilepsy surgery.

METHODS

The study was conducted as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for systematic literature review. Databases (PubMed Ovid, PubMed Medline, Web of Science, CINHAL, PsycInfo) were systematically searched in February 2021 using a defined search strategy and inclusion/exclusion criteria. Total 1304 articles were screened for titles and abstracts, and 54 full-text articles were retrieved for further assessment. We included 14 articles with critical quality assessment using two different tools for qualitative and questionnaire-based studies. A qualitative content analysis was performed to characterize caregiver experience, perception, and decision-making toward favorable or unfavorable opinions of epilepsy surgery.

RESULTS

Four concepts generated from the analysis may act as enablers or barriers to decision-making around epilepsy surgery: 1. Access to knowledge and information, 2. Communication and coordination issues, 3. Caregiver's emotional state, and 4. Socioeconomic effects. Subsequently, we provided a narrative synthesis of practice recommendations and a conceptual framework to adopt multi-pronged interventions to overcome identified diverse barriers to effective caregiver decision-making.

CONCLUSION

Multiple influences impact how caregivers decide about epilepsy surgery for their children, with no single factor identified as the primary driver for or against surgery. However, limited research has explored these influences. Future studies should focus on quantitatively examining factors to identify significant variables most likely to influence caregiver decision-making, ultimately overcoming barriers that limit utilization of epilepsy surgery as a treatment tool.

Underutilization of epilepsy surgery: Part II: Strategies to overcome barriers

Interventions focused on utilization of epilepsy surgery can be divided into groups: those that improve patients' access to surgical evaluation and those that facilitate completion of the surgical evaluation and treatment. Educational intervention, technological innovation, and effective coordination and communication can significantly improve patients' access to surgery. Patient and public facing, individualized (analog and/or digital) communication can raise awareness and acceptance of epilepsy surgery. Educational interventions aimed at providers may mitigate knowledge gaps using practical and concise consensus statements and guidelines, while specific training can improve awareness around implicit bias. Innovative technology, such as clinical decision-making toolkits within the electronic medical record (EMR), machine learning techniques, online decision-support tools, nomograms, and scoring algorithms can facilitate timely identification of appropriate candidates for epilepsy surgery with individualized guidance regarding referral appropriateness, postoperative seizure freedom rate, and risks of complication after surgery. There are specific strategies applicable for epilepsy centers' success: building a multidisciplinary setup, maintaining/tracking volume and complexity of cases, collaborating with other centers, improving surgical outcome with reduced complications, utilizing advanced diagnostics tools, and considering minimally invasive surgical techniques. Established centers may use other strategies, such as multi-stage procedures for multifocal epilepsy, advanced functional mapping with tailored surgery for epilepsy involving the eloquent cortex, and generation of fresh hypotheses in cases of surgical failure. Finally, improved access to epilepsy surgery can be accomplished with policy changes (e.g., anti-discrimination policy, exemption in transportation cost, telehealth reimbursement policy, patient-centered epilepsy care models, pay-per-performance models, affordability and access to insurance, and increased funding for research). Every intervention should receive regular evaluation and feedback-driven modification to ensure appropriate utilization of epilepsy surgery.

Considerations in preparing a multicenter study: Lessons learned from the Epilepsy Monitoring Unit Comfort Questionnaire (EMUCQ) validation feasibility study

PURPOSE

It is recommended to perform a pilot testing before conducting a validation study of a novel questionnaire. Pilot studies may serve different purposes. The aim of this study was to assess the feasibility of a multicenter validation study, to recruit additional study centers, and to undertake orientating descriptive item analysis of the 44-item Epilepsy Monitoring Unit (EMU) Comfort Questionnaire (EMUCQ).

METHODS

During a six-month sampling period, the EMUCQ was administered to eligible EMU patients. The patients filled out the questionnaire at two time points. Additional centers were recruited in Germany and Austria, and ethics votes obtained. In descriptive item analysis central tendency, variability, item distribution and item difficulty were calculated.

RESULTS

A total of 44 EMU patients participated in the study. Eight additional EMUs agreed to join the planned validation study. Recruitment of the centers took four months. Another six months passed to obtain all the ethics votes. Floor and ceiling effects could be detected in 32 items. One item with the lowest median showed the low item difficulty. Another five items showed medians with the height of 6. In four items, high difficulty indices could be observed.

CONCLUSION

A good network has turned out to be very helpful while planning a multicenter study. Enough time must be scheduled, because obtaining an ethics vote may take quite a long time. No conclusive statements regarding item properties could be made as this was a feasibility study.

Assessing comfort in the epilepsy monitoring unit: Development of an instrument

BACKGROUND/PURPOSE

Some patients perceive the experience of hospitalization in an epilepsy monitoring unit (EMU) to be an uncomfortable one. In order to provide comfort-enhancing measures, nurses need to assess comfort levels. For this purpose, Kolcaba developed the General Comfort Questionnaire (GCQ), which may be modified for usage in specific settings. The objective of this study was to develop an instrument to assess comfort of adult patients during hospitalization in an EMU, namely the Epilepsy Monitoring Unit Comfort Questionnaire (EMUCQ).

METHODS

The GCQ was translated from American English into German following the guidelines of the International Society for Pharmacoeconomics and Outcome Research (ISPOR). Three native German speakers with good command of the English language did forward translations. An expert who grew up bilingual did a backtranslation. For use in an EMU, literature-based setting-specific items were added. In a qualitative-descriptive study, cognitive debriefing with 25 patients was conducted using cognitive interviews. Qualitative data analysis was based on the framework method. In a quantitative-descriptive study, nine clinical experts assessed content validity.

RESULTS

For setting-specific modification, 12 items pertaining to surroundings, feeling observed, and feeling afraid of a seizure were added to the translated GCQ. Based on the initial content validity rating, 26 items remained unchanged, 12 items underwent revisions, and 14 items were omitted. Eight items were put aside for a follow-up rating in the context of cognitive debriefing. Cognitive interviewing revealed problems regarding the interpretation of items and missing items. According to the results, 27 items remained unchanged, 11 items were reworded, and six items were added. The final content validity rating showed item-content validity indices (I-CVI) between .33 and 1, and an average CVI on a scale level (S-CVI/ave) of .84.

CONCLUSIONS

Enhancing comfort is a fundamental nursing goal in demanding situations. Therefore, the contribution of nurses to the quality of individualized patient care is a substantial one. The EMUCQ is a valuable tool to support the assessment of comfort levels. The ISPOR guidelines proved to be useful to ensure high quality of the translated instrument. Using cognitive interviews enhanced the understandability of items and supported modification of the GCQ. At present, S-CVI/ave value of the EMUCQ is acceptable. Further testing is necessary.

The impact of the use of video-based educational interventions on patient outcomes in hospital settings: A scoping review

OBJECTIVE

To summarize the literature on the impact of video-based educational interventions on patient outcomes in inpatient settings as compared to standard education techniques.

METHODS

This review followed a scoping review methodology. English language articles were searched in Pubmed, Medline, Cochrane, and CINAHL databases. Inclusion criteria were: use of video-based educational interventions, and inpatient hospital settings. Abstracts were reviewed and selected according to predetermined criteria, followed by full-text scrutiny.

RESULTS

Sixty-two empirical studies were identified, with 38 (61%) reporting a significant positive effect of video-based educational interventions on patient outcomes, compared to control groups (i.e., standard education). Three different types of video-based educational intervention formats were identified: animated presentations, professionals in practice, and patient narratives. Outcome types included: knowledge-based, clinical, emotional, and behavioral, with knowledge-based most prevalent.

CONCLUSION

Video-based educational interventions are common in the hospital setting. These interventions are effective at improving short-term health literacy goals, but their impact on behavior or lifestyle modifications is unclear. Their effectiveness also depends on presentation format, timing, and the patient's emotional well-being.

PRACTICE IMPLICATIONS

Video-based educational delivery is effective for improving short-term health literacy, however a combination of approaches delivered over an extended period of time may support improving longer-term health outcomes.

Enhancing validity through cognitive interviewing. A methodological example using the Epilepsy Monitoring Unit Comfort Questionnaire

Aims

To identify problematic items, assess completeness and user‐friendliness, and undertake modifications to enhance face validity of the newly developed Epilepsy Monitoring Unit Comfort Questionnaire.

Design

Qualitative‐descriptive cross‐sectional study.

Methods

Five iterative rounds of cognitive interviewing were conducted with members of the target population between July ‐ November 2017. Think‐aloud technique, verbal probing, and observation were used, to assess how respondents understood and answered questions. Data analysis was based on the framework method; an eight‐column framework matrix was created for this purpose.

Results

In 25 interviews, problems regarding completeness of the item pool, comprehension of items, retrieval of information, judgment while finding answers and reporting the appropriate responses could be detected. According to the results, 27 items remained unchanged, 11 items were reworded, and six items were added. Instructions section of the questionnaire was reworked, too.

Conclusion

Although time‐consuming, cognitive interviewing turned out to be a valuable approach for revealing problems in an instrument, which would, otherwise, remain undetected and threaten validity.

Determination of Content Validity of the Epilepsy Monitoring Unit Comfort Questionnaire Using the Content Validity Index

BACKGROUND AND PURPOSE

The Epilepsy Monitoring Unit Comfort Questionnaire (EMUCQ) is a self-assessment instrument to measure perceived patient comfort during hospitalization in an EMU. This study aimed at initially determining the content validity by rating the content validity index (CVI).

METHODS

Nine experts judged the 60-item EMUCQ-1 by filling out a content validation form. The CVI was computed on item (I-CVI) and at an average scale (S-CVI/Ave) level.

RESULTS

As many as 26 items remained unchanged and 12 items were reworded to prepare the 38-item EMUCQ-2 (I-CVI scores ≥ .78). Fourteen items were omitted and an additional eight items were put aside for further evaluation. The S-CVI/Ave reached .90.

CONCLUSION

The first results indicate the EMUCQ-2 to be valid in terms of content. Further assessment by members of the target population is advisable.

Epilepsy monitoring - The patients' views: A qualitative study based on Kolcaba's Comfort Theory

PURPOSE

The aim of this qualitative study was to determine which perception of personal comfort patients name in the context of their hospitalization in an Austrian Epilepsy Monitoring Unit (EMU).

METHODS

Problem-centred interviews with twelve inpatients were conducted. Data analyses were done according to Mayring's qualitative content analyses following the technique of structuring-deductive category assignment.

RESULTS

Patients experienced different kinds of comfort along with their hospitalization in the EMU. Comfort-decreasing factors were bed rest, boredom, and waiting for possible seizures. As comfort-increasing factors, hope for enhanced seizure control, support by family and staff, and intelligible information about the necessity of restrictive conditions were identified.

CONCLUSIONS

The study results should assist health care professionals, enabling them to design comfort enhancing interventions for patients undergoing video-electroencephalography (EEG) investigations in an EMU. Some of these seem to be simple and obtainable without high financial or technical effort. Others are more complex and have to be further assessed for their feasibility.

Cognitive impairment in adults with epilepsy: The relationship between subjective and objective assessments of cognition

AIM

This study aimed to assess the relationship between objective measures of cognition and subjective perception of cognitive functioning reported by patients with epilepsy and their caregivers.

METHODS

One hundred patients with epilepsy attending hospital neurology outpatient clinics and their caregivers were enrolled in this study. The EpiTrack (version 1) brief cognitive screening tool was used to measure objective impairment, the ABNAS questionnaire (A-B Neuropsychological Assessment Schedule) to assess subjective cognitive performance, and a version of the ABNAS designed to be completed by caregivers (C-ABNAS) to document caregivers' views. Patient anxiety and depression were measured using the Hospital Anxiety and Depression Scale (HADS) and considered as covariates. Patients with an uncertain diagnosis of epilepsy or likely severe comorbid mood or anxiety disorders were excluded.

RESULTS

Data from 82 patients were analyzed after exclusion of patients with uncertain diagnoses or likely severe comorbid mood or anxiety disorders. Fifty-nine (72%) had a degree of objective cognitive impairment. Fifty (84.7%) of these 59 patients had 'high' ABNAS scores concordant with the objective assessment, and 43 (72.9%) had high C-ABNAS scores matching the abnormalities detected by objective screening. Of the 23 (28%) patients without objective cognitive impairment, seven (30.4%) had concordantly low ABNAS scores, and 10 (43.4%) had concordantly low C-ABNAS scores. Patient memory impairment was more often reported by patients themselves than by caregivers (p=0.011). Carers were significantly more likely to rate patients as having impaired motor coordination than patients themselves. A small part of the variance of the EpiTrack score was predicted by the C-ABNAS. Objective cognitive performance did not predict ABNAS or C-ABNAS scores.

CONCLUSIONS

Self-report or caregiver report questionnaires identify patients with epilepsy and objective cognitive impairment more accurately than patients with intact cognition. Those without objective evidence of cognitive impairment may, nevertheless, perceive themselves as having memory dysfunction; it is these patients, therefore, who most require both subjective and objective assessments of cognition, including carers' assessments, in order to establish the nature of their symptoms. None of these assessment measures can be used as a reliable proxy for another, each contributes individually to a comprehensive assessment of cognition, and all must be used in conjunction with measures of mood and anxiety.

Factors contributing to concerns of persons living with epilepsy

PURPOSE

To describe the concerns of Korean adults living with epilepsy and to compare the concerns of individuals with controlled and uncontrolled seizures.

METHODS

Outpatients filled out questionnaires, including the Hospital Anxiety and Depression Scale, the Quality of Life in Epilepsy-10 questionnaire, the stigma scale, and a questionnaire on episodes of discrimination. Patients were asked to fill out the Epilepsy Foundation of America (EFA) Concerns Index and to list their concerns on a blank sheet of paper.

RESULTS

Of the 178 participants, 152 described a total of 470 concerns, which could be assorted into 25 distinct concerns. Worrying about the hereditability of their condition was the only concern that differed significantly between individuals with controlled and uncontrolled seizures. Three significant factors were identified on the total EFA Concerns Index score: level of anxiety/depression (34.4%), age (6.3%), and degree of social discrimination (4.3%), resulting in a total explained variance of 45.0%.

CONCLUSIONS

Korean adults with epilepsy had various concerns, with some differing from those in Western populations. Anxiety/depression, age and degree of discrimination were significantly associated with the degree of concern in Korean patients with epilepsy.

The amygdala and anxiety after epilepsy surgery

The relationship between amygdalar volume and anxiety after epilepsy surgery was explored. Participants comprised patients who underwent mesial temporal (n=26) or non-mesial temporal resections (n=16) and 41 neurologically normal controls. Anxiety was prospectively measured preoperatively and for the first 12 months postoperatively using criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Amygdalar volumetry was performed on preoperative and control T1-weighted MRI scans. Resection of an ipsilateral amygdala of normal volume, relative to controls, was associated with postoperative anxiety in patients with mesial temporal resections, regardless of seizure outcome [F(1, 22)=5.17, P<0.05]. There was no relationship between amygdalar volume and anxiety in patients with non-mesial temporal resections, or between contralateral amygdalar volume and anxiety in patients with mesial temporal resections (P>0.05 for all comparisons). In conclusion, resection or deafferentation of an amygdala with a volume within the normal range was associated with increased postoperative anxiety.

Association of information satisfaction, psychological distress and monitoring coping style with post-decision regret following breast reconstruction

Little is known of the psychosocial factors associated with decision regret in the context of breast reconstruction following mastectomy for breast cancer treatment. Moreover, there is a paucity of theoretically-based research in the area of post-decision regret. Adopting the theoretical framework of the Monitoring Process Model (Cancer 1995;76(1):167-177), the current study assessed the role of information satisfaction, current psychological distress and the moderating effect of monitoring coping style to the experience of regret over the decision to undergo reconstructive surgery. Women (N=123) diagnosed with breast cancer who had undergone immediate or delayed breast reconstruction following mastectomy participated in the study. The majority of participants (52.8%, n=65) experienced no decision regret, 27.6% experienced mild regret and 19.5% moderate to strong regret. Bivariate analyses indicated that decision regret was associated with low satisfaction with preparatory information, depression, anxiety and stress. Multinominal logistic regression analysis showed, controlling for mood state and time since last reconstructive procedure, that lower satisfaction with information and increased depression were associated with increased likelihood of experiencing regret. Monitoring coping style moderated the association between anxiety and regret (beta=-0.10, OR=0.91, p=0.01), whereby low monitors who were highly anxious had a greater likelihood of experiencing regret than highly anxious high monitors.

Coping strategies of panic and control subjects undergoing lactate infusion during magnetic resonance imaging confinement

The psychological reactions and coping strategies used in response to a behavioral contingency (confinement in a magnetic resonance imaging [MRI] scanner) during a biological challenge (sodium lactate infusion) were systematically studied in 13 subjects with panic disorder (PD) and 11 control subjects using the Claustrophobia Questionnaire (CQ) and the Revised Ways of Coping Checklist (RWCCL). All participants were able to successfully complete the experimental procedure. Findings suggest between-group coping strategy differences in response to general stressors, but relative convergence of coping strategies in response to the experimental procedure, with relatively greater emphasis on problem-focused coping approaches. These observations suggest that PD patients are able to engage in effective coping strategies in response to stressful but highly structured experimental situations. An overall pre-post MR scanning reduction in the fear of restriction but not suffocation was observed for the combined sample, primarily reflecting changes in the control group. Among PD subjects, higher levels of suffocation fears were maintained despite emergence of more problem-focused coping in the experimental situation.

Treatment of anxiety in epilepsy

The association of anxiety with epilepsy has been noted for centuries. Anxiety can occur at different phases of a seizure event and present with diverse clinical symptoms similar to those seen in panic, obsessive-compulsive, or generalized anxiety disorders. Pharmacologic and nonpharmacologic treatments of anxiety in the context of epilepsy are discussed.

The coordinated psychosocial and neurologic care of children with seizures and their families

SUMMARY

As the medical and surgical management of epilepsy continues to advance, issues associated with the quality of life of patients and their families can be addressed. Whenever associated with other handicaps, such as learning disabilities, attentional or behavioral disorders, and problems in psychological adjustment, dual-diagnosis issues must be identified. To provide comprehensive care for children with epilepsy, a team approach to psychosocial assessment and treatment must be provided and coordinated with neurologic care. When the age-related needs in the life stage of the individual and family are identified, the best possible adaptation of the patient and his or her family can be supported.
