Characteristics, outcomes and health care utilization of patients with acute myeloid leukemia aged 70 years or older: A single-center retrospective analysis.

The overall prognosis of older patients with acute myeloid leukemia (AML) is dismal. Only a small subgroup experiences long-term survival. The discrimination between patients who are candidates for potentially curative approaches and those who are not is crucial since - in addition to differences in terms of AML-directed treatment - different policies concerning intensive care unit (ICU) admission and involvement of specialized palliative care (SPC) seem obvious. To shed more light on characteristics, outcomes and health care utilization of older individuals with AML, we conducted an analysis comprising 107 consecutive patients with newly diagnosed AML aged ≥70 years treated at an academic tertiary care center in Germany between 1 January 2015, and 31 December 2020. Median age was 75 years (range: 70-87 years); 45% of patients were female. The proportion of patients receiving intensive induction chemotherapy was 35%, 55% had low-intensity treatment and 10% did not receive AML-directed treatment or follow-up ended before treatment initiation. At least one ICU admission was documented for 47% of patients; SPC was involved in 43% of cases. Median follow-up was 199 days. The median overall survival (OS) was 2.5 months; the 1-year OS rate was 16%. Among patients who died during observation, the median proportion of time spent in the hospital between AML diagnosis and death was 56%. The most common places of death were normal wards (31%) and the ICU (28%). Patients less frequently died in a palliative care unit (14%) or at home (12%). In summary, results of the present analysis confirm the unfavorable prognosis of older patients with AML despite intensive health care utilization. Future efforts in this patient group should aim at optimizing the balance between appropriate AML-directed treatment on the one hand and health care utilization including ICU stays on the other hand.

Quality of life from childhood to adulthood: Perspectives from adult patients with pediatric-onset intestinal failure.

Adult patients with pediatric onset short bowel syndrome (SBS) or intestinal failure (IF) have been described as a distinct population warranting further research. The aim of this exploratory study aimed was to offer initial insights into this population's navigation of childhood, adolescence, and transition into adulthood. Both quantitative and qualitative data were collected from a convenience sample of adults with pediatric-onset SBS/IF using a disease-specific pilot survey; 14 questionnaires were completed. Responses indicated childhood and adulthood were complex and marked by joys and trials, while adolescence was experienced by many as a particularly challenging time. As adults, numerous patients experienced barriers to accessing the medical care they desired and described difficulties finding experienced and knowledgeable providers who listened and offered individualized care. This study highlights the importance of further studying this unique patient population, suggesting it can offer critical insights to inform the development of interventions and transition programs.

[Overdosing of direct oral anticoagulants]. / Überdosierung von direkten oralen Antikoagulanzien.

BACKGROUND: Direct oral anticoagulants (DOAC) are increasingly used for prophylaxis and treatment of thromboembolic events. Incorrectly dosed DOAC treatment is associated with excess mortality. PURPOSE: This article aims at raising awareness of DOAC overdosing and its causes as well as presenting a diagnostic and therapeutic work-up. MATERIAL AND METHODS: Based on a case presentation, a structured review of the current literature on DOAC overdosing was performed and treatment recommendations were extracted. RESULTS: In addition to wittingly or unwittingly increased DOAC intake, common causes of overdose are inadequate dose adjustment for concomitant medication or comorbidities. Global coagulation testing should be supplemented with DOAC-specific testing. Severe bleeding and the need for invasive diagnostics or urgent surgery represent indications for treating DOAC overdoses. Based on the cause of an DOAC overdose, active charcoal, endoscopic pill rescue, antagonization with idarucizumab or andexanet alfa and the targeted substitution of coagulation factors represent treatment options. CONCLUSION: The sensitization of clinicians is important to ensure a timely diagnosis and adequate treatment of DOAC overdosing. This report provides an overview of current knowledge on diagnostics and treatment; however, further studies are necessary to improve the existing algorithms.

Exploring the impact of pediatric short bowel syndrome on parent well-being using a disease-specific pilot survey.

BACKGROUND: Children with short bowel syndrome (SBS) have complex care needs, most of which are met in the home by family caregivers who may experience a range of stressors unique to this experience. Prior research suggests that parents of children with SBS have poorer health-related quality of life than peers parenting children without health needs, but the mechanisms shaping parent outcomes are understudied. METHODS: A pilot survey was developed using a community-driven research design to measure the impact of disease-specific items on parent-perceived well-being. The cross-sectional survey, which included both closed-ended and open-ended items, was distributed to a convenience sample of parents of children with SBS. Quantitative and qualitative data were integrated for a mixed-methods analysis of how individual items impacted parent well-being. RESULTS: Twenty parents completed the survey. Sleep interruptions, lack of support and resources, and psychological stressors and their mental health implications were more frequently reported as stressors than logistics related to caregiving (e.g., managing therapies and preparing specialized meals). CONCLUSION: The impact of a child's SBS on parent well-being may stem mainly from three interconnected domains: poor sleep and its consequences, lack of access to support and resources, and a range of psychological stressors that affect parent mental health. Understanding the mechanisms through which SBS shapes parent well-being is a necessary first step for developing targeted interventions to support parents and provide family-centered care.

A diagnostic challenge-First case of chronic lymphatic leukemia-associated necrotizing sweet syndrome.

Sweet syndrome, also known as acute febrile neutrophilic dermatosis, is a rare disorder typically characterized by the clinical triad including a sudden onset of fever, painful skin lesions, and neutrophilia. The histopathological findings are a dense neutrophilic infiltrate and oedema of the dermis and epidermis without evidence of a vasculitis. Besides treatment of the underlying cause, sweet syndrome is typically treated with high-dose corticosteroids leading to a relapse-free response in 70% of patients. However, if left unrecognized or untreated, the condition may lead to serious complications. Here, we report on the case of a 38-year-old patient in whom, under the assumption of the presence of necrotizing fasciitis, exarticulation of the right arm was performed. In the absence of pathogen detection and insufficient response to anti-infective therapies, the diagnosis of a sweet syndrome was assumed and, later, confirmed by an excellent response to high-dose administration of systematic glucocorticoids. The case emphasizes the need to be aware of this rare syndrome, which can be easily misdiagnosed due to its close resemblance to infection and stresses the need of further research to define distinct diagnostic tools.

Advocating for a patient- and family centered care approach to management of short bowel syndrome.

Patient- and family centered care (PFCC) is a model of providing healthcare that incorporates the preferences, needs, and values of the patient and their family and is built on a solid partnership between the healthcare team and patient/family. This partnership is critical in short bowel syndrome (SBS) management since the condition is rare, chronic, involves a heterogenous population, and calls for a personalized approach to care. Institutions can facilitate the practice of PFCC by supporting a teamwork approach to care, which, in the case of SBS, ideally involves a comprehensive intestinal rehabilitation program consisting of qualified healthcare practitioners who are supported with the necessary resources and budget. Clinicians can engage in a range of processes to center patients and families in the management of SBS, including fostering whole-person care, building partnerships with patients and families, cultivating communication, and providing information effectively. Empowering patients to self-manage important aspects of their condition is an important component of PFCC and can enhance coping to chronic disease. Therapy nonadherence represents a breakdown in the PFCC approach to care, especially when nonadherence is sustained, and the healthcare provider is intentionally misled. An individualized approach to care that incorporates patient/family priorities should ultimately enhance therapy adherence. Lastly, patients/families should play a central role in determining meaningful outcomes as it relates to PFCC and shaping the research that affects them. This review highlights needs and priorities of patients with SBS and their families and suggests ways to address gaps in existing care to improve outcomes.

[Non-utilisation of medical services during the COVID-19 pandemic among persons with chronic diseases]. / Nichtinanspruchnahme medizinischer Leistungen in der COVID-19-Pandemie bei Personen mit chronischen Erkrankungen.

INTRODUCTION: The COVID-19 pandemic is also impacting the medical care for other diseases. The extent to which people with chronic diseases are affected by the suspension of medical services is investigated-differentiating between patient and provider perspectives. METHOD: A cross-sectional study was conducted based on data from the longitudinal Hamburg City Health Study (HCHS). The study population was all HCHS participants (a sample of the population of Hamburg, 45-74 years) between April 2020 and November 2021. Utilisation of medical services was collected via the "COVID-19-module" of the HCHS. The chronic conditions included cardiovascular disease, kidney and lung disease, cancer and diabetes mellitus; analyses were descriptive and multivariate. RESULTS: Of the 2047 participants, 47.9% had at least one previous illness. Of those with pre-existing conditions, 21.4% had at least one healthcare service suspended or an appointment cancelled. In addition, 15.4% stated that they decided by themselves not to attend a doctor's appointment. Specialist care services (43.8% of all cancellations) were cancelled more frequently than general practitioner care (16.6%). After adjustment for age, gender and education, lung disease (OR 1.80; p < 0.008) and cancer (OR 2.33; p < 0.001) were found to be independent risk factors for appointment cancellations by healthcare providers. Of cancellations by patients, 42.2% were due to their fear of an infection with the coronavirus SARS-CoV­2. DISCUSSION: Health policy and the media are faced with the challenge of dealing with fears of infection in the population in such a way that they do not lead to an avoidance of necessary care services.

Impact of timing and precision of histopathological diagnosis on outcomes of patients with Burkitt lymphoma and high-grade B-cell lymphoma.

BACKGROUND: Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL) are aggressive B-cell non-Hodgkin lymphomas (B-NHL) with a generally favorable prognosis after immunochemotherapy. The outcome of BL is superior to DLBCL. In 2016, a distinct group of lymphomas displaying characteristics of both BL and DLBCL (high grade B-cell lymphoma, HGBL) was introduced into the WHO classification. Histopathological discrimination of BL, DLBCL, and HGBL may be challenging. Data on the frequency of histopathological difficulties resulting in revision of the final diagnosis of BL/DLBCL/HGBL and its impact on the prognosis are limited. METHODS: We assessed histopathological features and clinical outcomes of 66 patients with suspected diagnosis of BL at the reporting institution between 2010 and 2020. RESULTS: The median age was 51 years (range 19-82) and final histopathological diagnosis revealed BL (n = 40), DLBCL (n = 12), or HGBL (n = 14). Patients with DLBCL and HGBL were either treated with DLBCL-directed (83.3% and 35.7%) or BL-directed (16.7% and 64.3%) protocols. Patients in whom diagnosis was revised from DLBCL to BL after initiation of DLBCL-directed treatment had a significantly inferior progression-free survival (PFS) than patients initially diagnosed with BL (p = 0.045), thus resembling rather the prognosis of DLBCL/HGBL. There was no difference between patients with DLBCL and HGBL, respectively, regarding PFS and OS (p = 0.38 and p = 0.27). CONCLUSION: These results suggest that timely and precise histopathological diagnosis as well as reference histopathological review of the underlying lymphoma is critical to determine up-front treatment strategies. Consequently, selection of more aggressive treatment protocols in case of difficulties with discrimination between DLBCL/HGBL/BL may be a reasonable approach.

Discipline-Specific Perspectives on Caring for Babies with Trisomy 13 or 18 in the Neonatal Intensive Care Unit.

OBJECTIVE: Care offerings vary across medical settings and between families for babies with trisomy 13 or 18. The purpose of this qualitative descriptive study was to explore nurse, advanced practice practitioner, and neonatologist perspectives on care for babies with trisomy 13 or 18 in the intensive care unit. STUDY DESIGN: Voice-recorded qualitative interviews occurred with 64 participants (41 bedside nurses, 14 advance practice practitioners, and 9 neonatologists) from two neonatal intensive care units (NICU) in the midwestern United States. Consolidated Criteria for Reporting Qualitative Research guidelines were followed. Content analyses occurred utilizing MAXQDA (VERBI Software, 2020). RESULTS: Over half of NICU staff perceived care for babies with trisomy 13 or 18 as different from care for other babies with critical chronic illness. Qualitative themes included internal conflict, variable presentation and prognosis, grappling with uncertainty, family experiences, and provision of meaningful care. Neonatologists emphasized the variability of presentation and prognosis, while nurses emphasized provision of meaningful care. Phrases "hard/difficult" were spoken 31 times; primarily describing the comorbidities, complexities, and prognostic uncertainty. CONCLUSION: Care for babies with these genetic diagnoses reveals need for a shared dialogue not only with families but also across staff disciplines. While perspectives differ, participants depicted striving to offer compassionate, family-centered care while also balancing biomedical uncertainty about interventions for children with trisomy 13 and 18. KEY POINTS: · Care for babies with trisomy 13 or 18 has been recognized as shifting.. · Controversy exists across the diverse and changing range of care models.. · This study describes perspectives of bedside neonatal nurses, advanced practitioners, and neonatologists.. · Differences in perspectives warrant attentiveness to insights and dialogue across disciplines..

A beautiful struggle: Parent-perceived impact of short bowel syndrome on child and family wellbeing.

BACKGROUND: Despite considerable improvements in outcomes for children with short bowel syndrome (SBS), many clinicians remain pessimistic about long-term quality of life (QoL) for this population. METHODS: The validated FaMM tool was used to measure parent-perceived impact of the child's condition on child and family life. Partnered disease-specific survey questions relevant to child's overall wellbeing and family function were additionally completed and reported. The cross-sectional surveys were distributed to a convenience sample of parents of children with SBS. Child and family wellbeing were described and compared across child age group and involvement of an intestinal rehabilitation program (IRP). Multivariate regression analyses investigated associations between outcomes and IRP management. Open-ended responses were analyzed to investigate perceived impact of the child's SBS on the parent. RESULTS: Seventeen parents completed both surveys; 71% perceived child QoL as higher today than what they had originally been told to expect. Child daily life and family difficulty scores suggest parents perceived both to be fairly "normal". While acknowledging effort invested in condition management, parents perceived high competence in managing their child's condition; 56% perceived personal growth resulting from their child's SBS journey. IRP management was associated with better child daily life (4.11, p = 0.015), family difficulty (-4.85, p = 0.048), and family management ability (4.28, p = 0.014) scores. CONCLUSIONS: Many parents perceive child and family life with SBS to be fairly "normal", manage their child's care with great competence, and report personal growth because of their child's SBS journey. Additional research inclusive of diverse patient and parent backgrounds is warranted. LEVEL OF EVIDENCE: prognosis study; Level IV.

Care Provider Behaviors That Shape Parent Identity as a "Good Parent" to Their Seriously Ill Child.

Background: Parents of medically complex children hold deeply personal definitions of how to be "good parents" that guide their medical decision making and interactions with providers and are impacted by provider behaviors. Objective: This study explored whether and how these beliefs are shaped by interactions with care providers and which provider behaviors foster or impede parents' ability to achieve their "good parent" definitions. Methods: A 63-item web-based survey distributed by an online support network for parents of medically complex children. Responses to closed- and open-ended questions from 67 caregivers based in the United States and Europe were analyzed. Results: Respondents' medical decisions are driven by goals of unselfishly doing what is best for my child (61%) and being my child's voice (18%). Almost half indicated that their personal "good parent" definition was impacted by provider behaviors or interactions with physicians or nurses. Although most parents reported wanting trusted care providers to ask them about their personal "good parent" definition, only 7% had ever been directly asked by members of their care teams about this topic. Provider behaviors such as kind and caring interactions, acknowledging the parents' role in caring for the child, and truly seeing the child as more than a diagnosis were reported as fostering caregivers' ability to achieve their "good parent" beliefs. Conclusions: The findings indicate that trusted provider-initiated conversations about "good parent" beliefs would be well received and are an opportunity to improve family-centered care. Care provider behaviors deemed by parents as supportive facilitate their efforts to achieve their "good parent" beliefs.

Homestead together: Pediatric palliative care telehealth support for rural children with cancer during home-based end-of-life care.

BACKGROUND: Children with terminal cancer and their families describe a preference for home-based end-of-life care. Inadequate support outside of the hospital is a limiting factor in home location feasibility, particularly in rural regions lacking pediatric-trained hospice providers. METHODS: The purpose of this longitudinal palliative telehealth support pilot study was to explore physical and emotional symptom burden and family impact assessments for children with terminal cancer receiving home based-hospice care. Each child received standard of care home-based hospice care from an adult-trained rural hospice team with the inclusion of telehealth pediatric palliative care visits at a scheduled minimum of every 14 days. RESULTS: Eleven children (mean age 11.9 years) received pediatric palliative telehealth visits a minimum of every 14 days, with an average of 4.8 additional telehealth visits initiated by the family. Average time from enrollment to death was 21.6 days (range 4-95). Children self-reported higher physical symptom prevalence than parents or hospice nurses perceived the child was experiencing at time of hospice enrollment with underrecognition of the child's emotional burden. At the time of hospice enrollment, family impact was reported by family caregivers as 46.4/100 (SD 18.7), with noted trend of improved family function while receiving home hospice care with telehealth support. All children remained at home for end-of-life care. CONCLUSION: Pediatric palliative care telehealth combined with adult-trained rural hospice providers may be utilized to support pediatric oncology patients and their family caregivers as part of longitudinal home-based hospice care.

Actual Solidarity through Virtual Support: A Pilot Descriptive Study of an Online Support Group for Bereaved Parents.

Background: Hospital-based support for bereaved parents is regarded as best practice. Little is known about parental perceptions or programmatic potential of online grief support. Objectives: To learn from bereaved parent participants' experiences with an online support group to include perceptions of technology acceptance and group communication dynamics. Design: Descriptive study reporting on an eight-week online bereavement support group offered during summer 2020. Subjects and Setting: Inclusive of six bereaved parent participants in the Midwestern United States. Measurements: Post-intervention survey consisting of 49-items with the Technology Acceptance Model and Other Communicated Perspective-Taking Ability instruments embedded. Results: Five bereaved mothers and one father (mean age 32 years) residing an average 126 miles from hospital participated in an online support group in a timeframe seven months to one year from the death of their child. Intensity of grief emotion (5/6 parents) and physical distance (4/6 parents) were notable barriers to in-person visits to the hospital, where bereavement support was to be offered. Parents uniformly reported feeling benefit from the program and satisfaction with the program. Respondents self-reported gaining improved communication (4/6 parents), coping (3/6 parents), peer support (3/6 parents), education (3/6 parents), and emotional expression (3/6 parents). Mean scores on the technology acceptance and communication experiences scales were 4.7/5. The virtual format was an acceptable modality with perceived supportive interpersonal communication dynamics. Conclusion: Pediatric palliative care teams may consider the offering of online bereavement support groups. Further research is warranted on the impact and outcomes of online bereavement support groups for bereaved parents.

Human Connection and Technology Connectivity: A Systematic Review of Available Telehealth Survey Instruments.

CONTEXT: The current upsurge in telehealth use in palliative and hospice care warrants consideration of patient, family caregiver, and interdisciplinary palliative perspectives on telehealth modality and communication experiences. Currently, telehealth experiences and encounters are being described but not yet extensively evaluated by palliative care teams. OBJECTIVES: To locate survey instruments available to assess telehealth interactions, to determine the content and constructs covered by the available instruments, and to describe the patient populations previously surveyed by the existing instruments. METHODS: This study and its reporting followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with the protocol registered in The International Prospective Register of Systematic Reviews. Three databases were searched with over 3100 articles analyzed for use of a telehealth survey instrument. RESULTS: Twelve telehealth communication assessment instruments were identified with a mean length of 20 questions, primarily Likert-scale responses with one inclusive of free text and one qualitative inquiry survey. Three inquired only into modality, four queried communication, and five studied both modality and communication experience. Existing telehealth survey instruments are unidirectional in exploring patient or family experience, with two inclusive of provider perspectives. Participant demographics are notably underreported in telehealth experience studies with a frank lack of diversity in ethnic/racial, geographic, age, educational, and income representativeness in current telehealth survey instrument respondents. CONCLUSION: Palliative care teams may consider familiarity with telehealth survey instrument as an essential component to progress from description of telehealth use to evaluation of telehealth encounters. Current survey instrument outcome reports do not represent inclusivity or diversity, although telehealth is now being clinically applied across settings.

Honoring the Good Parent Intentions of Courageous Parents: A Thematic Summary from a US-Based National Survey.

BACKGROUND: Parents of children with complex medical needs describe an internal, personal definition of "trying to be a good parent" for their loved child. Gaps exist in the current "good parent concept" literature: (1) When the idea of "trying to be a good parent" comes into existence for parents, (2) How parents' definition of "being a good parent" may change over time and may influence interactions with the child, and (3) Whether parents perceive attainment of their personal definition. AIM: The purpose of this study was to explore these current gaps in the "good parent concept" knowledge base from the perspective of parents of children with chronic or complex illness. MATERIALS AND METHODS: These themes were explored through a 63-item, mixed-method web-based survey distributed by the Courageous Parents Network (CPN), an organization and online platform that orients, educates, and empowers families and providers caring for seriously ill children. RESULTS: The term "trying to be a good parent" resonated with 85% of the 67 responding parents. For the majority of parents, the concept of "being a good parent" started to exist in parental awareness before the child's birth (70.2%) and evolved over time (67.5%) to include less judgment and more self-compassion. Parents identified their awareness of their child's prognosis and changing health as influential on their "trying to be a good parent" concept. Parental advocacy, child's age, and duration of illness were reported as influencing parental perceptions of having achieved their definition of "being a good parent". CONCLUSIONS: Familiarity with parental perspectives on their parenting goodness and goals is a necessary core of family-centric health care.

Haploinsufficiency due to a novel ACO2 deletion causes mitochondrial dysfunction in fibroblasts from a patient with dominant optic nerve atrophy.

ACO2 is a mitochondrial protein, which is critically involved in the function of the tricarboxylic acid cycle (TCA), the maintenance of iron homeostasis, oxidative stress defense and the integrity of mitochondrial DNA (mtDNA). Mutations in the ACO2 gene were identified in patients suffering from a broad range of symptoms, including optic nerve atrophy, cortical atrophy, cerebellar atrophy, hypotonia, seizures and intellectual disabilities. In the present study, we identified a heterozygous 51 bp deletion (c.1699_1749del51) in ACO2 in a family with autosomal dominant inherited isolated optic atrophy. A complementation assay using aco1-deficient yeast revealed a growth defect for the mutant ACO2 variant substantiating a pathogenic effect of the deletion. We used patient-derived fibroblasts to characterize cellular phenotypes and found a decrease of ACO2 protein levels, while ACO2 enzyme activity was not affected compared to two age- and gender-matched control lines. Several parameters of mitochondrial function, including mitochondrial morphology, mitochondrial membrane potential or mitochondrial superoxide production, were not changed under baseline conditions. However, basal respiration, maximal respiration, and spare respiratory capacity were reduced in mutant cells. Furthermore, we observed a reduction of mtDNA copy number and reduced mtDNA transcription levels in ACO2-mutant fibroblasts. Inducing oxidative stress led to an increased susceptibility for cell death in ACO2-mutant fibroblasts compared to controls. Our study reveals that a monoallelic mutation in ACO2 is sufficient to promote mitochondrial dysfunction and increased vulnerability to oxidative stress as main drivers of cell death related to optic nerve atrophy.

Human Touch via Touchscreen: Rural Nurses' Experiential Perspectives on Telehealth Use in Pediatric Hospice Care.

CONTEXT: Telemedicine has the potential to extend care reach and access to home-based hospice services for children. Few studies have explored nurse perspectives regarding this communication modality for rural pediatric cohorts. OBJECTIVES: The objective of this qualitative study was to learn from the experiences of rural hospice nurses caring for children at the end of life using telehealth modalities to inform palliative communication. METHODS: Voice-recorded qualitative interviews with rural hospice nurse telehealth users inquiring on nurse experiences with telehealth. Semantic content analysis was used. RESULTS: About 15 hospice nurses representing nine rural hospice agencies were interviewed. Nurses participated in an average of eight telehealth visits in the three months prior. Nurses were female with a mean age of 38 years and an average of seven years of hospice nursing experience. Five themes about telehealth emerged: accessible support, participant inclusion, timely communication, informed and trusted planning, and familiarity fostered. Each theme had both benefits and cautions associated as well as telehealth suggestions. Nurses recommended individualizing communication, pacing content, fostering human connection, and developing relationships even with technology use. CONCLUSION: The experiences of nurses who use telehealth in their care for children receiving end-of-life care in rural regions may enable palliative care teams to understand both the benefits and challenges of telehealth use. Nurse insights on telehealth may help palliative care teams better honor the communication needs of patients and families while striving to improve care access.

Usability on the p-medicine infrastructure: an extended usability concept.

Usability testing methods are nowadays integrated into the design and development of health-care software, and the need for usability in health-care information technology (IT) is widely accepted by clinicians and researchers. Usability assessment starts with the identification of specific objectives that need to be tested and continues with the definition of evaluation criteria and monitoring procedures before usability tests are performed to assess the quality of all services and tasks. Such a process is implemented in the p-medicine environment and gives feedback iteratively to all software developers in the project. GCP (good clinical practice) criteria require additional usability testing of the software. For the p-medicine project (www.p-medicine.eu), an extended usability concept (EUC) was developed. The EUC covers topics like ease of use, likeability, and usefulness, usability in trial centres characterised by a mixed care and research environment and by extreme time constraints, confidentiality, use of source documents, standard operating procedures (SOA), and quality control during data handling to ensure that all data are reliable and have been processed correctly in terms of accuracy, completeness, legibility, consistence, and timeliness. Here, we describe the p-medicine EUC, focusing on two of the many key tools: ObTiMA and the Ontology Annotator (OA).
