RESUMO

OBJECTIVES: Electronic patient portals (ePortals) can facilitate greater healthcare democratization by providing patients and/or their authorized care partners with secure access to their medical records when and where needed. Such democratization can promote effective healthcare provider-patient partnerships, shared decision-making, and greater patient engagement in managing their health condition. This study examined the usefulness of providing individualized services and care in epilepsy (PiSCES), an epilepsy ePortal, as an enabler of more democratized epilepsy care. METHODS: Seventy-two individuals with epilepsy and 18 care partners were invited to report on their experience of interacting via PiSCES with clinical documents (epilepsy care summary record; epilepsy clinic letters) authored about them by healthcare providers. The OpenNotes reporting tool was adapted to capture participant experience. RESULTS: Twenty-five percent of invited patients and 44% of invited care partners reported on interacting with their epilepsy care summary; 14% of patients and 67% of care partners invited reported on their epilepsy clinic letters. Participant testimonials illustrate the value of PiSCES in: promoting autonomy, aiding memory, developing the knowledgeable patient, and enhancing healthcare partnerships. Ninety-six percent and 100% of respondents, respectively, reported understanding their epilepsy care summary and epilepsy clinic letter; 77% said the summary described their epilepsy history to date; 96% indicated that the letter provided an accurate description of their clinical encounter; 92% and 96%, respectively, valued access to their summary record and clinic letters; 77% of summary record and 73% clinic letter respondents reported learning something about their epilepsy or the healthcare service via PiSCES. Illustrating their potential patient and care partner safety role, 42% respondents identified inaccuracies in their clinical documents which were subsequently resolved by a clinician. SIGNIFICANCE: In the post-digital world highly customized on-demand products and services have come to be expected. Similarly, in epilepsy care, technologies such as PiSCES can enable more personalized, transparent, and engaging services.

RESUMO

As part of our ongoing interest in patient- and family-centered care in epilepsy, we began, before the onset of the CoVID-19 pandemic, to evaluate the concerns and preferences of those delivering and receiving care via telemedicine. CoVID-19 arrived and acted as an unexpected experiment in nature, catalyzing telemedicine's widespread implementation across many disciplines of medicine. The arrival of CoVID-19 in Ireland gave us the opportunity to record these perceptions pre- and post-CoVID. Data were extracted from the National Epilepsy Electronic Patient Record (EEPR). Power BI Analytics collated data from two epilepsy centers in Dublin. Analysis of data on reasons for using the telephone support line was conducted. A subset of patients and clinicians who attended virtual encounters over both periods were asked for their perception of telemedicine care through a mixed methods survey. Between 23rd December 2019 and 23rd March 2020 (pre-CoVID era), a total of 1180 patients were seen in 1653 clinical encounters. As part of a telemedicine pilot study, 50 of these encounters were scheduled virtual telephone appointments. Twenty eight surveys were completed by clinicians and 18 by patients during that period. From 24th March 2020 to 24th June 2020, 1164 patients were seen in 1693 encounters of which 729 (63%) patients were seen in 748 scheduled virtual encounters. 118 clinician impressions were captured through an online survey and 75 patients or carers completed a telephone survey during the post-CoVID era. There was no backlog of appointments or loss of care continuity forced by the pandemic. Clinicians expressed strong levels of satisfaction, but some doubted the suitability of new patients to the service or candidates for surgery receiving care via telemedicine. Patients reported positive experiences surrounding telephone appointments comparing them favorably to face-to-face encounters. The availability of a shared EEPR demonstrated no loss of care contact for patients with epilepsy. The survey showed that telemedicine is seen as an effective and satisfactory method of delivering chronic outpatient care.

RESUMO

BACKGROUND: Coproduced epilepsy care sees people with epilepsy (PwE), their care-proxies, and healthcare providers (HCPs), working together as partners to build strong relationships, improve communication, trust, and share decision-making. Coproduction underpins good quality patient- and family-centered care (PFCC) that is responsive to individual patient needs, preferences, and values. By facilitating information sharing and exchange between partners, electronic patient portals (ePortal) can enable coproduction. This paper explores what HCPs, PwE, and their care-proxies value from their user experience of PiSCES, the Irish epilepsy ePortal. METHODS: A purposeful sample of actors involved in the receipt and delivery of epilepsy care and services were recruited via adult epilepsy centers at St James's and Beaumont Hospitals in Dublin. Interactive codesign sessions, surveys, and focus groups were used to elicit perspectives from PwE, care-proxies, and HCPs to understand their perception of how PiSCES could enhance or inhibit the epilepsy care process. RESULTS: Results illustrate that participants welcome the role PiSCES can play in: empowering PwE/care-proxies, strengthening confidence in the healthcare system; aiding memory; advancing health literacy, motivating PwE to understand their condition better; acting as a passport of care between different clinical settings; and creating a foundation for stronger coproduction partnerships. PiSCES was generally embraced; however, some HCPs expressed plausible concerns about how clinical implementation might impact their work practices. CONCLUSION: "Nothing about me without me" is a core value of the PiSCES initiative, recognizing that people need to be included in the planning of their own treatment and care. Our data show that PwE, their care-proxies, and HCPs value PiSCES potential, particularly in bolstering healthcare partnerships that foster inclusion, confidence, and trust.

RESUMO

BACKGROUND: This manuscript presents a framework to guide the identification and assessment of ethical opportunities and challenges associated with electronic patient records (EPR). The framework is intended to support designers, software engineers, health service managers, and end-users to realise a responsible, robust and reliable EPR-enabled healthcare system that delivers safe, quality assured, value conscious care. METHODS: Development of the EPR applied ethics framework was preceded by a scoping review which mapped the literature related to the ethics of EPR technology. The underlying assumption behind the framework presented in this manuscript is that ethical values can inform all stages of the EPR-lifecycle from design, through development, implementation, and practical application. RESULTS: The framework is divided into two parts: context and core functions. The first part 'context' entails clarifying: the purpose(s) within which the EPR exists or will exist; the interested parties and their relationships; and the regulatory, codes of professional conduct and organisational policy frame of reference. Understanding the context is required before addressing the second part of the framework which focuses on EPR 'core functions' of data collection, data access, and digitally-enabled healthcare. CONCLUSIONS: The primary objective of the EPR Applied Ethics Framework is to help identify and create value and benefits rather than to merely prevent risks. It should therefore be used to steer an EPR project to success rather than be seen as a set of inhibitory rules. The framework is adaptable to a wide range of EPR categories and can cater for new and evolving EPR-enabled healthcare priorities. It is therefore an iterative tool that should be revisited as new EPR-related state-of-affairs, capabilities or activities emerge.

RESUMO

OBJECTIVES: The current coronavirus disease 2019 (COVID-19) pandemic stresses an urgency to accelerate much-needed health service reform. Rapid and courageous changes being made to address the immediate impact of the pandemic are demonstrating that the means and technology to enable new models of health care exist. For example, innovations such as electronic patient portals (ePortal) can facilitate (a) radical reform of outpatient care; (b) cost containment in the economically constrained aftermath of the pandemic; (c) environmental sustainability by reduction of unnecessary journeys/transport. Herein, the development of Providing Individualised Services and Care in Epilepsy (PiSCES), an ePortal to the Irish National Epilepsy Electronic Patient Record, is demonstrated. This project, which pre-dates the COVID-19 crisis, aims to facilitate better patient- and family-centered epilepsy care. METHODS: A combination of ethnographic research, document analysis, and joint application design sessions was used to elicit PiSCES requirements. From these, a specification of desired modules of functionality was established and guided the software development. RESULTS: PiSCES functional features include "My Epilepsy Care Summary," "My Epilepsy Care Goals," "My Epilepsy Clinic Letters," "Help Us Measure Your Progress," "Prepare For Your Clinic Visit," "Information for Your Healthcare Provider." The system provides people with epilepsy access to, and engages them as co-authors of, their own medical record. It can promote improved patient-clinician partnerships and facilitate patient self-management. SIGNIFICANCE: In the aftermath of COVID-19, it is highly unlikely that the healthcare sector will return to a "business as usual" way of delivering services. The pandemic is expected to accelerate adoption of innovations like PiSCES. It is therefore a catalyst for change that will deliver care that is more responsive to individual patient needs and preferences.

RESUMO

Although 70% of people with epilepsy (PWE) achieve seizure freedom following an appropriate antiepileptic drug (AED) regime, evidence suggests that adherence to AEDs by PWE is suboptimal. Nonadherence to AEDs is associated with increased morbidity, mortality, emergency department visits, and hospitalizations, with reduced adherence also correlating to a lower quality of life, decreased productivity, and loss of employment. Furthermore, research indicates that medication errors which are widespread in chronic disease are less well studied in epilepsy but are likely also to contribute to avoidable disease morbidity and mortality. The goals of this project were to determine rates of medication adherence by self-reported questionnaire and its links to perceived medication error in a cohort of PWE attending a general epilepsy outpatient clinic. Following a plan-do-study-act cycle, it was found that the most appropriate methodology for conducting was in the form of a bespoke 9-item self-administered questionnaire. One hundred eighty-six PWE completed a nine-question questionnaire asking patients about their own medication adherence habits and their perception that they were previously exposed to medication error. This study found that 41% of respondents reported suboptimal adherence to AED therapy, while 28.5% of respondents self-reported that they unintentionally do not take their AED medication on an occasional, regular, or frequent basis. A 5.9% of respondents self-reported that they intentionally do not take their medication as prescribed. A 6% of respondents self-reported that they are both unintentionally and intentionally nonadherent to their AED therapy. No significant associations were demonstrated between age, sex, perceived effectiveness of medication, feelings of stigma/embarrassment, adverse effects or additional neurological comorbidities, and unintentional or intentional nonadherence. A 28.5% of respondents to the questionnaire reported that they perceived themselves to have been subjected to medication error. Prescribing errors were the most common form of perceived medication error, followed by dispensing errors, then administration errors. Significant associations were found between ineffective medication and feelings of stigma or embarrassment about epilepsy with perceived prescribing errors. Intentional nonadherence to medication was significantly associated with perceived dispensing errors.

RESUMO

The National Clinical Programme for Epilepsy (NCPE) in Ireland aims to deliver a holistic model of integrated person-centered care (PCC) that addresses the full spectrum of biomedical and psychosocial needs of people with epilepsy (PwE). However, like all strategic plans, the model encompasses an inherent set of assumptions about the readiness of the environment to implement and sustain the actions required to realize its goals. In this study, through the lens of PwE, the Irish epilepsy care setting was explored to understand its capacity to adopt a new paradigm of integrated PCC. Focus groups and semi-structured one-to-one interviews were employed to capture the qualitative experiences of a sample of Irish PwE (n = 27) in the context of the care that they receive. Participants were from different regions of the country and were aged between 18 and 55 years with 1 to 42 years since diagnosis (YSD). Highlighting a gap between policy intent and action on the ground, findings suggest that patient readiness to adopt a new model of care cannot be assumed. Expectations, preferences, behaviors, and values of PwE may sustain the more traditional constructions of healthcare delivery rather than the integrated PCC goals of reform. These culturally constituted perceptions illustrate that PwE do not instinctively appreciate the goals of healthcare reform nor the different behavior expected from them within a reformed healthcare system. Recalibrating deep-rooted patient views is necessary to accomplish the aspirations of integrated PCC. Patient engagement emphasizing the meaningful role that they can play in shaping their healthcare services is vital.

RESUMO

BACKGROUND: Electronic patient record (EPR) technology is a key enabler for improvements to healthcare service and management. To ensure these improvements and the means to achieve them are socially and ethically desirable, careful consideration of the ethical implications of EPRs is indicated. The purpose of this scoping review was to map the literature related to the ethics of EPR technology. The literature review was conducted to catalogue the prevalent ethical terms, to describe the associated ethical challenges and opportunities, and to identify the actors involved. By doing so, it aimed to support the future development of ethics guidance in the EPR domain. METHODS: To identify journal articles debating the ethics of EPRs, Scopus, Web of Science, and PubMed academic databases were queried and yielded 123 eligible articles. The following inclusion criteria were applied: articles need to be in the English language; present normative arguments and not solely empirical research; include an abstract for software analysis; and discuss EPR technology. RESULTS: The medical specialty, type of information captured and stored in EPRs, their use and functionality varied widely across the included articles. Ethical terms extracted were categorised into clusters 'privacy', 'autonomy', 'risk/benefit', 'human relationships', and 'responsibility'. The literature shows that EPR-related ethical concerns can have both positive and negative implications, and that a wide variety of actors with rights and/or responsibilities regarding the safe and ethical adoption of the technology are involved. CONCLUSIONS: While there is considerable consensus in the literature regarding EPR-related ethical principles, some of the associated challenges and opportunities remain underdiscussed. For example, much of the debate is presented in a manner more in keeping with a traditional model of healthcare and fails to take account of the multidimensional ensemble of factors at play in the EPR era and the consequent need to redefine/modify ethical norms to align with a digitally-enabled health service. Similarly, the academic discussion focuses predominantly on bioethical values. However, approaches from digital ethics may also be helpful to identify and deliberate about current and emerging EPR-related ethical concerns.

RESUMO

Models of care developed to improve the lives of people with chronic diseases highlight integrated care as essential to meeting their needs and achieving person (patient)-centered care (PCC). Nevertheless, barriers to collaborative practice and siloed work environments persist. To set in motion some groundwork for intersectoral collaboration this study brought two expert groups of epilepsy care practitioners together to engage in participatory action research (PAR). The expert practitioner groups were hospital-based epilepsy specialist nurses (ESNs) and community-based resource officers (CROs). The PAR highlighted, that while the participants share a mutual interest in caring for people with epilepsy, underdeveloped CRO-ESN relationships, arising from unconscious bias and ambiguity can result in missed opportunities for optimal care coordination with consequent potential for unnecessary replication and waste of finite resources. However, through dialogue and critical self-reflection, a growing emotional connection between the disciplines evolved over the course of the PAR. This allowed for buds of collaboration to develop with CROs and ESNs working together to tackle some of the key barriers to their collaboration.

RESUMO

OBJECTIVES: Both clinical genomics and e-Health technology are changing the way medicine is being practiced. Although the basic clinical methodology of good medical care will remain unchanged, the combined power of genomics and electronic health records has the capability of enhancing, and in some cases transforming, the practice of medicine. This is particularly true in the care of patients with complex long-term medical conditions such as chronic refractory epilepsy, especially in those with related complex comorbidities including intellectual disability and psychiatric disease. METHODS: Herein we outline the development and integration of an epilepsy genomics module into a preexisting epilepsy electronic patient record (EPR) system. RESULTS: We describe how this EPR infrastructure is used to facilitate discussion at multidisciplinary clinical meetings around molecular diagnosis and resulting changes in management. SIGNIFICANCE: This work illustrates the role of eHealth technology in embedding genomics into the clinical pathway.

RESUMO

In line with healthcare reform across the world, the National Clinical Programme for Epilepsy (NCPE) in Ireland describes a model that aims to achieve holistic integrated person (patient)-centered care (PCC). While generally welcomed by stakeholders, the steps required to realize the NCPE ambition and the preparedness of those involved to make the journey are not clear. This study explored the perceptions of healthcare providers in the Irish epilepsy care ecosystem to understand their level of readiness to realize the benefits of an integrated PCC model. Ethnographic fieldwork including observations of different clinical settings across three regions in Ireland and one-to-one interviews with consultant epileptologists (n = 3), epilepsy specialist nurses (n = 5), general practitioners (n = 4), and senior healthcare managers (n = 3) were conducted. While there is a person-centered ambiance and a disposition toward advancing integrated PCC, there are limits to the readiness of the epilepsy care environment to fully meet the aspirations of healthcare reform. These are the following: underdeveloped healthcare partnerships;, poor care coordination;, unintended consequences of innovation;, and tension between pace and productivity. In the journey from policy to practice, the following multiple tensions collide: policy aims to improve services for all patients while simultaneously individualizing care; demands for productivity limit the time and space required to engage in incremental and iterative improvement initiatives. Understanding these tensions is an essential first step on the pathway to integrated PCC implementation.

RESUMO

Temporal cortex abnormalities are common in patients with mesial temporal lobe epilepsy due to hippocampal sclerosis (MTLE+HS) and believed to be relevant to the underlying mechanisms. In the present study, we set out to determine the familiarity of temporal cortex morphologic alterations in a cohort of MTLE+HS patients and their asymptomatic siblings. A surface-based morphometry (SBM) method was applied to process MRI data acquired from 140 individuals (50 patients with unilateral MTLE+HS, 50 asymptomatic siblings of patients, and 40 healthy controls). Using a region-of-interest approach, alterations in temporal cortex morphology were determined in patients and their asymptomatic siblings by comparing with the controls. Alterations in temporal cortex morphology were identified in MTLE+HS patients ipsilaterally within the anterio-medial regions, including the entorhinal cortex, parahippocampal gyrus, and temporal pole. Subtle but similar pattern of morphology changes with a medium effect size were also noted in the asymptomatic siblings. These localized alterations were related to volume loss that appeared driven by shared contractions in cerebral cortex surface area. These findings indicate that temporal cortex morphologic alterations are common to patients and their asymptomatic siblings and suggest that such localized traits are possibly heritable.

RESUMO

The goal of this study was to characterize cerebral cortex thickness patterns in juvenile myoclonic epilepsy (JME). Surface-based morphometry (SBM) was applied to process brain magnetic resonance images acquired from 24 patients with JME and 40 healthy controls and quantify cerebral cortex thickness. Differences in cortical thickness between patients and controls were determined using generalized linear model (covariates: age and gender). In patients with JME, thickness increase was detected bilaterally within localized regions in the orbitofrontal and mesial frontal cortices. Such thickness patterns coexisted with significant bilateral reduction in thalamic volume. These findings confirm that the underlying mechanisms in JME are related to aberrant corticothalamic structure and indicate that frontal cortex abnormalities are possibly linked to regional increase in cerebral cortical thickness.

RESUMO

PURPOSE: Atypical morphology of the surface of the cerebral cortex may be related to abnormal cortical folding (gyrification) and therefore may indicate underlying malformations of cortical development (MCDs). Using magnetic resonance imaging (MRI)-based analysis, we examined cortical morphology in patients with juvenile myoclonic epilepsy (JME). METHODS: MRI data was collected for 24 patients with JME and 40 demographically matched healthy controls. FreeSurfer, an automated cortical surface reconstruction method, was applied to compare cortical morphology between patients and controls. Areas of anomalous cortical morphology were defined as regions of interest (ROIs) to contrast regional cortical parameters, such as surface area, average thickness, and mean curvature between patients and controls. KEY FINDINGS: In patients with JME, changes to cortical morphology were detected in several regions. In the left hemisphere, these were in insular and cingulate cortices, occipital pole, and middle temporal and fusiform gyri. In the right hemisphere, changes were detected in insular cortex, inferior temporal gyrus, and precuneus. Further analysis of ROIs revealed that these changes are related to differences in surface area rather than average cortical thickness. In addition, mean curvature abnormalities were detected in the insula bilaterally, the left cingulate cortex, and right inferior temporal gyrus. SIGNIFICANCE: The morphologic findings in this study suggest that structural abnormalities in JME extend beyond mesial frontal lobe regions of the brain. These may be indicative of areas of subtle cortical folding abnormality related to early disruption of cortical development.

RESUMO

PURPOSE: To date, magnetic resonance imaging (MRI)-based studies of the cerebral cortex in mesial temporal lobe epilepsy (MTLE) have focused primarily on investigating cortical volume and thickness. However, volume is a composite of surface area and thickness, each reflecting distinct neurobiologic and genetic processes. The goal of this study was to investigate cerebral cortex (1) surface area, (2) surface geometric distortion, and (3) thickness in MTLE with hippocampal sclerosis (HS). METHODS: Seventy patients with "sporadic" unilateral MTLE + HS and 40 healthy controls underwent T(1) -weighted MRI. Processing MR images using an automated cortical surface reconstruction method (FreeSurfer), we quantified cortical surface area, surface geometric distortion (metric distortion), and thickness at each vertex across the entire cortex. Differences between patients and controls were determined using generalized linear models. Separate linear regression models were employed to assess the relationship between cortical surface area and hippocampal volume as well as a series of important clinical features of the condition. KEY FINDINGS: We detected an asymmetric reduction in cortical surface area, predominantly in ipsilateral mesial and anterior temporal lobe subregions, of patients with MTLE + HS. Changes in surface geometric features were also evident and closely mirrored surface area patterns. In contrast, cortical thinning appeared dispersed across the cortex bilaterally. The regression models revealed that ipsilateral hippocampal volume was a significant predictor of temporal lobe surface area changes. SIGNIFICANCE: Our findings indicate that contraction in surface area, rather than cortical thinning, explains ipsilateral mesial and anterior temporal lobe atrophy in patients with MTLE with HS. Furthermore, the alterations in surface geometry indicate folding abnormality involving the same regions. Cortical surface changes may represent sequelae of the disease or deviant cortical development.

RESUMO

Advances in medical science and technology, together with improved medical and nursing care, are continuously improving health outcomes in chronic illness, including epilepsy. The consequent increasing diagnostic and therapeutic complexity is placing a burgeoning strain on health care systems. In response, an international move to transform chronic disease management (CDM) aims to optimize the quality and safety of care while containing health care costs. CDM models recommend: integration of care across organizational boundaries that is supported with information and communication technology; patient self-management; and guideline implementation to promote standardized care. Evidence of the effectiveness of CDM models in epilepsy care is presented in this review article.

RESUMO

PURPOSE: To investigate cerebral cortical surface morphology in a magnetic resonance (MRI)-negative temporal lobe epilepsy (TLE) cohort, and to differentiate between the effects on cortical morphology of cerebral volume loss associated with TLE, and abnormalities suggestive of malformations of cortical development (MCDs). METHODS: MRI data was gathered for 29 MRI-negative patients and 40 neurologically normal controls. Automated methods of surface reconstruction were applied to all MRI data for the purposes of localized analysis of cortical curvature. As an adjunct to this analysis, measures of whole-brain gray and white matter volumes, as well as cortical thickness, were also generated to determine the degree of whole-brain volume loss in TLE, and its impact on cortical morphology. RESULTS: Automated analysis of the average cortical surface of the patient group revealed an area of abnormal cortical curvature in the basal left temporal lobe. The presence of whole-brain volume loss in TLE was confirmed and found not to contribute to the cortical curvature abnormality in the temporal lobe. These results support the hypothesis that cortical curvature abnormalities in TLE may be indicative of a subtle MCD. DISCUSSION: Subtle MCDs such as abnormal indices of curvature may be associated with partial epilepsy. Analysis of these parameters may increase the diagnostic yield from MRI.

RESUMO

BACKGROUND: Temporal lobe epilepsy is associated with a significant risk of psychosis but there are only limited studies investigating the underlying neurobiology. AIMS: To characterise neuroanatomical changes in temporal lobe epilepsy and comorbid psychosis. METHOD: The study population comprised all individuals with temporal lobe epilepsy on the epilepsy database at the National Centre for Epilepsy and Epilepsy Neurosurgery in Ireland (Beaumont Hospital) between 2002 and 2006. Ten people with temporal lobe epilepsy with psychosis were matched for age, gender, handedness, epilepsy duration, seizure laterality, severity of epilepsy and anti-epileptic medication with ten comparison participants with temporal lobe epilepsy only. Participants received a magnetic resonance imaging scan and voxel-based morphometry analyses were applied to grey and white matter anatomy. RESULTS: Significant grey matter reduction was found bilaterally in those with temporal lobe epilepsy with psychosis in the temporal lobes in the inferior, middle and superior temporal gyri and fusiform gyri, and unilaterally in the left parahippocampal gyrus and hippocampus. Significant extratemporal grey matter reduction was found bilaterally in the insula, cerebellum, caudate nuclei and in the right cingulum and left inferior parietal lobule. Significant white matter reduction in those with temporal lobe epilepsy with psychosis was found bilaterally in the hippocampus, parahippocampal/fusiform gyri, middle/inferior temporal gyri, cingulum, corpus callosum, posterior thalamic radiation, anterior limb of internal capsule and white matter fibres from the caudate nuclei, and unilaterally in the left lingual gyrus and right midbrain and superior temporal gyrus. CONCLUSIONS: Significant grey and white matter deficits occur in temporal lobe epilepsy with psychosis. These encompass the medial temporal lobe structures but also extend to lateral temporal and extratemporal regions. Some of these deficits overlap with those found in schizophrenia.
