Global assessment of the knowledge and confidence in managing allergic disorders among primary care pediatricians across Europe: An EAACI task force report

BACKGROUND

Pediatricians are often the first point of contact for children in Primary Care (PC), but still perceive gaps in their allergy knowledge. We investigated self-perceived knowledge gaps and educational needs in pediatricians across healthcare systems in Europe so that future educational initiatives may better support the delivery of allergy services in PC.

METHOD

A multinational survey was circulated to pediatricians who care for children and adolescents with allergy problems in PC by the EAACI Allergy Educational Needs in Primary Care Pediatricians Task Force from February to March 2023. A 5-point Likert scale was used to assess the level of agreement with questionnaire statements. Thirty surveys per country were the cut-off for inclusion and statistical analysis.

RESULTS

In this study, 1991 respondents were obtained from 56 countries across Europe and 210 responses were from countries with a cut-off below 30 participants per country. Primary care pediatricians (PCPs) comprised 74.4% of the respondents. The majority (65.3%) were contracted to state or district health services. 61.7% had awareness of guidelines for onward allergy referral in their countries but only 22.3% were aware of the EAACI competencies document for allied health professionals for allergy. Total sample respondents versus PCPs showed 52% and 47% of them have access to allergy investigations in their PC facility (mainly specific IgE and skin prick tests); 67.6% and 58.9% have access to immunotherapy, respectively. The main barrier to referral to a specialist was a consideration that the patient's condition could be diagnosed and treated in this PC facility, (57.8% and 63.6% respectively). The main reasons for referral were the need for hospital assessment, and partial response to first-line treatment (55.4% and 59.2%, 47% and 50.7%, respectively). Learning and assessment methods preference was fairly equally divided between Traditional methods (45.7% and 50.1% respectively) and e-learning 45.5% and 44.9%, respectively. Generalist physicians (GPs) have the poorest access to allergy investigations (32.7%, p = .000). The majority of the total sample (91.9%) assess patients with allergic pathology. 868 (43.6%) and 1117 (46.1%), received allergy training as undergraduates and postgraduates respectively [these proportions in PCPs were higher (45% and 59%), respectively]. PCPs with a special interest in allergology experienced greater exposure to allergy teaching as postgraduates. GPs received the largest amount of allergy teaching as undergraduates. Identifying allergic disease based on clinical presentation, respondents felt most confident in the management of eczema/atopic dermatitis (87.4%) and rhinitis/asthma (86.2%), and least confident in allergen immunotherapy (36.9%) and latex allergy (30.8%).

CONCLUSION

This study exploring the confidence of PCPs to diagnose, manage, and refer patients with allergies, demonstrated knowledge gaps and educational needs for allergy clinical practice. It detects areas in need of urgent improvement especially in latex and allergen immunotherapy. It is important to ensure the dissemination of allergy guidelines and supporting EAACI documents since the majority of PCPs lack awareness of them. This survey has enabled us to identify what the educational priorities of PCPs are and how they would like to have them met.

Split-bolus single-phase versus single-bolus split-phase CT acquisition protocols for staging in patients with testicular cancer: A retrospective study

INTRODUCTION

Computed tomography (CT) imaging has become indispensable in the management of medical oncology patients. Risks associated with high cumulative effective dose (CED) are relevant in testicular cancer patients. Split-bolus protocols, whereby the contrast medium injection is divided into two, followed by combining the required phase images in a single scan acquisition has been shown to provide images of comparable image quality and less radiation dose compared to single-bolus split-phase CT for various indications. We retrospectively evaluated the performance of split-bolus and single-bolus protocols in patients having follow-up CT imaging for testicular cancer surveillance.

METHODS

45 patients with testicular cancer undergoing surveillance CT imaging of the thorax, abdomen, and pelvis who underwent split-bolus and single-bolus protocols were included. Quantitative image quality analysis was conducted by placing region of interests in pre-defined anatomical sub-structures within the abdominal cavity. The signal-to-noise ratio (SNR) and radiation dose in the form of dose length product (DLP) and effective dose (ED) were recorded.

RESULTS

The DLP and ED for the single-bolus, split-phase acquisition was 506 ± 89 mGy cm and 7.59 ± 1.3 mSv, respectively. For the split-bolus, single-phase acquisition, 397 ± 94 mGy∗cm and 5.95 ± 1.4 mSv, respectively (p < 0.000). This represented a 21.5 % reduction in radiation dose exposure. The SNR for liver, muscle and fat for the single-bolus were 7.4, 4.7 and 8, respectively, compared to 5.5, 3.8 and 7.4 in the split-bolus protocol (p < 0.001).

CONCLUSION

In a testicular cancer patient cohort undergoing surveillance CT imaging, utilization of a split-bolus single-phase acquisition CT protocol enabled a significant reduction in radiation dose whilst maintaining subjective diagnostic acceptability.

IMPLICATIONS FOR PRACTICE

Use of split-bolus, single-phase acquisition has the potential to reduce CED in surveillance of testicular cancer patients.

Consensus criteria for chronic rhinosinusitis disease control: an international Delphi Study

BACKGROUND

Chronic rhinosinusitis (CRS) disease control is a global metric of disease status for CRS. While there is broad acceptance that it is an important treatment goal, there has been inconsistency in the criteria used to define CRS control. The objective of this study was to identify and develop consensus around essential criteria for assessment of CRS disease control.

METHODS

Modified Delphi methodology consisting of three rounds to review a list of 24 possible CRS control criteria developed by a 12-person steering committee. The core authorship of the multidisciplinary EPOS 2020 guidelines was invited to participate.

RESULTS

Thirty-two individuals accepted the invitation to participate and there was no dropout of participants throughout the entire study (3 rounds). Consensus essential criteria for assessment of CRS control were: overall symptom severity, need for CRS-related systemic corticosteroids in the prior 6 months, severity of nasal obstruction, and patient-reported CRS control. Near-consensus items were: nasal endoscopy findings, severity of smell loss, overall quality of life, impairment of normal activities and severity of nasal discharge. Participants’ comments provided insights into caveats of, and disagreements related to, near-consensus items.

CONCLUSIONS

Overall symptom severity, use of CRS-related systemic corticosteroids, severity of nasal obstruction, and patient-reported CRS control are widely agreed upon essential criteria for assessment of CRS disease control. Consideration of near-consensus items to assess CRS control should be implemented with their intrinsic caveats in mind. These identified consensus CRS control criteria, together with evidence-based support, will provide a foundation upon which CRS control criteria with wide-spread acceptance can be developed.

EUFOREA summit in Brussels 2023: inspiring the future of allergy & respiratory care

In March 2023, the European Forum for Research and Education in Allergy and Airways diseases (EUFOREA) organized its bi-annual Summit in Brussels with expert panel members of EUFOREA, representatives of the EUFOREA patient advisory board, and the EUFOREA board and management teams. Its aim was to define the research, educational and advocacy initiatives to be developed by EUFOREA over the next 2 years until the 10th anniversary in 2025. EUFOREA is an international non-for-profit organization forming an alliance of all stakeholders dedicated to reducing the prevalence and burden of chronic allergic and respiratory diseases via research, education, and advocacy. Based on its medical scientific core competency, EUFOREA offers an evidence-supported platform to introduce innovation and education in healthcare leading to optimal patient care, bridging the gap between latest scientific evidence and daily practice. Aligned with the mission of improving health care, the expert panels of asthma, allergic rhinitis (AR), chronic rhinosinusitis (CRS) & European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS), allergen immunotherapy (AIT) and paediatrics have proposed and elaborated a variety of activities that correspond to major unmet needs in the allergy and respiratory field. The current report provides a concise overview of the achievements, ambitions, and action plan of EUFOREA for the future, allowing all stakeholders in the allergy and respiratory field to be up-dated and inspired to join forces in Europe and beyond.

Identification of the Language Network from Resting-State fMRI in Patients with Brain Tumors: How Accurate Are Experts?

BACKGROUND AND PURPOSE

Resting-state fMRI helps identify neural networks in presurgical patients who may be limited in their ability to undergo task-fMRI. The purpose of this study was to determine the accuracy of identifying the language network from resting-state-fMRI independent component analysis (ICA) maps.

MATERIALS AND METHODS

Through retrospective analysis, patients who underwent both resting-state-fMRI and task-fMRI were compared by identifying the language network from the resting-state-fMRI data by 3 reviewers. Blinded to task-fMRI maps, these investigators independently reviewed resting-state-fMRI ICA maps to potentially identify the language network. Reviewers ranked up to 3 top choices for the candidate resting-state-fMRI language map. We evaluated associations between the probability of correct identification of the language network and some potential factors.

RESULTS

Patients included 29 men and 14 women with a mean age of 41 years. Reviewer 1 (with 17 years' experience) demonstrated the highest overall accuracy with 72%; reviewers 2 and 3 (with 2 and 7 years' experience, respectively) had a similar percentage of correct responses (50% and 55%). The highest accuracy used ICA50 and the top 3 choices (81%, 65%, and 60% for reviewers 1, 2, and 3, respectively). The lowest accuracy used ICA50, limiting each reviewer to the top choice (58%, 35%, and 42%).

CONCLUSIONS

We demonstrate variability in the accuracy of blinded identification of resting-state-fMRI language networks across reviewers with different years of experience.

The EUFOREA pocket guide for chronic rhinosinusitis

Chronic rhinosinusitis (CRS) is known to affect around 5 % of the total population, with major impact on the quality of life of those severely affected (1). Despite a substantial burden on individuals, society and health economies, CRS often remains underdiagnosed, under-estimated and under-treated (2). International guidelines like the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) (3) and the International Consensus statement on Allergy and Rhinology: Rhinosinusitis 2021 (ICAR) (4) offer physicians insight into the recommended treatment options for CRS, with an overview of effective strategies and guidance of diagnosis and care throughout the disease journey of CRS.

321 UNMET NEEDS AFTER STROKE

Background

Unmet needs, such as lack of access to rehabilitation, support and information, are experienced by a high proportion of stroke survivors after discharge from acute and rehabilitation services. The UK guidelines on stroke (2016) recommend that all patients should be offered a structured health and social care review at 6 months post-stroke. However, no such clinics exist to date in Ireland. We aimed to explore the extent of unmet needs in the catchment area of a large teaching hospital.

Methods

A random selection of patients 6-months post-stroke were contacted by telephone and unmet needs were assessed using a validated tool, Post-Stroke Checklist. Following analysis of data, the need for a pilot clinic was identified. A separate random selection of patients discharged from acute services 6 months previously were invited to attend a review clinic. Patients were assessed using an adapted version of the Greater Manchester Stroke Assessment Tool. Assessments were conducted jointly by a physiotherapist and a speech and language therapist, and appropriate onward referrals were made.

Results

Telephone clinic: 51 patients completed the checklist. The most prevalent symptoms reported were fatigue (75%), reduced participation in hobbies and activities, decline in cognition (61%) and mobility problems (59%). Review clinic: 21 patients attended. The most prevalent symptoms reported were reduced memory/concentration (71%), low mood (71%), unintentional weight loss/gain (62%), and reduced mobility (43%). Onward referrals were made for in 16/21 (76%) cases; physiotherapy (n=12), occupational therapy (n=7), speech and language therapy (n=7), clinical nutrition (n=5), social work (n=7), psychology (n=5).

Conclusion

Data from this exploratory study supports previous research indicating a high number of stroke survivors with unmet needs. This highlights the importance of establishing post-acute stroke review clinics and pathways in the Irish setting.

303 SCREENING INSTRUMENTS TO PREDICT ADVERSE OUTCOMES FOR UNDIFFERENTIATED OLDER ADULTS ATTENDING THE EMERGENCY DEPARTMENT: RESULTS OF SOAED PROSPECTIVE COHORT STUDY

Background

Frailty screening facilitates the stratification of older adults at most risk of adverse events for urgent assessment and subsequent intervention in the acute or community setting. We assessed the validity of the ISAR (Identification of Seniors at Risk), Rockwood Clinical Frailty Scale (CFS), PRISMA-7 and InterRAI-ED at predicting adverse outcomes at 30 days and six months among older adults presenting to the ED.

Methods

A prospective cohort study of consecutive older adults (≥65 years) who presented to the ED at a University Hospital was conducted. The ISAR, CFS, PRISMA-7 and InterRAI-ED were performed by an experienced ED research nurse. Blinded follow-up telephone interviews were completed at 30 days and six months to assess the incidence of mortality, ED re-attendance, hospital readmission, functional decline and nursing home admission. The sensitivity and specificity of the screening tools were calculated using 2×2 tables.

Results

419 patients were recruited with 49% female and a mean age of 76.9 years (SD 7.15). The prevalence of frailty varied across the screening tools (ISAR, 47% vs InterRAI-ED, 63%). At 30-days, mortality rate was 5.4%, ED re-attendance 16.9%, hospital readmission 13.6%, functional decline 47.1% and nursing home admission 7.3%. Older adults who screened positive for frailty demonstrated an increased risk of all adverse outcomes at 30 days and 6 months, regardless of frailty screening tool administered. All tools had a relatively high sensitivity but low specificity. The ISAR was the only tool which was statistically significant at predicting all outcomes at 30 days.

Conclusion

The ISAR, CFS, PRISMA-7 and InterRAI-ED demonstrated modest validity at predicting adverse outcomes at 30 days and 6 months. We would recommend the implementation of one of these frailty screening tools in Irish EDs to support clinicians in identifying older adults most likely to benefit from specialised geriatric assessment and intervention in the hospital or community setting.

238 THE IMPACT OF COVID-19 ON ACUTE STROKE TREATMENT

Background

Acute stroke management is time critical. Treatment options are dictated by time of symptom onset. 2019 Irish National Audit of Stroke (INAS) showed less than 50% stroke cases arrived in hospital within three hours of symptoms and national average rate of thrombolysis was 11%. The median time Door-To-Needle time (DTN) was 56 minutes, and to thrombectomy 93 and 240 minutes ‘direct to mothership’ / ‘drip and ship’ transfer to thrombectomy centre respectively.

Methods

Retrospective review of all stroke FAST calls on our acute stroke database in TUH from July 2019 -2021. Data was analysed pre (up until March 2020) and during COVID-19 pandemic.

Results

FAST protocol imaging was obtained in 78% of cases (464/594). Documented time of symptom onset to CT was 1:50:00 pre-Covid-19 and 2:26:00 during Covid (p<0.001). ED registration to CT was 28mins pre-Covid-19 and 30mins during Covid (p<0.001). The median DTN time was 41mins pre-Covid-19 (n=21), and 54mins during Covid-19 (n=37).

Conclusion

In contrast to INAS COVID-19 report, median DTN times and thrombolysis rates dis-improved at TUH. Trends observed probably reflect multiple factors; patient hesitation to attend ED; patient isolation from family; busier ambulance service; Infection control protocols. We observed small but significant change in door-to-CT time but a more significant increase in DTN. This may reflect time taken donning Personal Protective Equipment (PPE) or general increased ED activity. Understanding the impact of COVID-19 on acute stroke treatment metrics in addition to differences at sites may identify targets for national quality improvement in service delivery.

265 A PHYSIOTHERAPY-LED TRANSITION TO HOME INTERVENTION FOR OLDER ADULTS FOLLOWING EMERGENCY DEPARTMENT DISCHARGE: A PILOT FEASIBILITY RANDOMISED-CONTROLLED TRIAL

Background

Older adults frequently attend the Emergency Department (ED) and experience high rates of adverse outcomes following ED presentation including functional decline, ED re-presentation and unplanned hospital admission. The development of effective interventions to prevent such outcomes is a key priority for research and service provision. A presentation to an ED can be viewed as an opportunity to assess those at risk of adverse outcomes and initiate a care plan in those deemed as ‘high risk'. Our aim was to evaluate the feasibility of a physiotherapy led integrated care intervention for older adults discharged from the ED (ED-PLUS).

Methods

Older adults presenting to the ED with undifferentiated medical complaints and discharged within 72 hours were computer randomised in a ratio of 1:1:1 to deliver usual care, Comprehensive Geriatric Assessment (CGA) in the ED, or ED-PLUS (Trial registration: NCT04983602). ED-PLUS is an evidence-based and stakeholder-informed intervention to bridge the care transition between the ED and community by initiating a CGA in the ED and implementing a six-week, multi-component, self-management programme in the patient’s own home. Feasibility (recruitment and retention rates) and acceptability of the programme were assessed quantitatively and qualitatively. Functional decline was examined post-intervention using the Barthel Index. All outcomes were assessed by a research nurse blinded to group allocation.

Results

29 participants were recruited, indicating 97% of our recruitment target. 90% of participants completed the ED-PLUS intervention. All participants expressed positive feedback about the intervention. The incidence of functional decline at 6 weeks was 10% in the ED-PLUS group versus 70-89% in the usual care and CGA-only groups.

Conclusion

High adherence and retention rates were observed among participants and preliminary findings indicate a lower incidence of functional decline in the ED-PLUS group. Recruitment challenges existed in the context of COVID-19. Data collection is ongoing for six-month outcomes.

Adolescents' dietary behaviour: The interplay between home and school food environments

In the UK, school food standards have looked to improve the nutritional profile of school food provision and the choices made; however, adolescents' choices tend to bias towards micronutrient poor and energy dense options. This study aimed to explore how adolescents make their school food choices, along with how they engage with their environments whilst selecting food. Seven focus group interviews took place with adolescents (n = 28; 13-14 years) in a secondary school in Northern England. Discussions with participants were audio-recorded, transcribed verbatim and then analysed using an inductive thematic approach. Six themes emerged from the data: (1) parents' and adolescents' roles in the home food environment, (2) burgeoning food autonomy, (3) school food choice factors, (4) social aspects of school food, (5) home versus school, (6) food knowledge & beliefs. Adolescents identified two distinct environments during the focus group discussions: the home and school environments. Adolescents juxtaposed the two, in terms of food provision, food choices, rules and customs surrounding food choice. This juxtaposition emerged as an indirect but important influence on adolescents' school food choices. The school and home environments both (in)directly influence adolescents' school food choices, which involve an integration of multiple, often conflicting influences. Adolescents may adopt a number of unhelpful dietary rationalisations as they try to manage and reconcile these influences. Consultation, together with consideration of relevant food choice models, is required to identify opportunities to influence adolescents' food choices at school.

941 EFFECTIVENESS OF ACUTE GERIATRIC UNIT CARE AMONG HOSPITALISED OLDER ADULTS WITH ACUTE MEDICAL COMPLAINTS: A META-ANALYSIS

Introduction

Older adults are clinically heterogeneous and are at increased risk of adverse outcomes during hospitalisation due to the presence of multiple comorbid and complex conditions. This systematic review and meta-analysis aims to update and synthesise the totality of research evidence on the effectiveness of acute geriatric unit (AGU) care for older adults admitted to hospital with acute medical complaints.

Method

MEDLINE, CINAHL, CENTRAL, and Embase databases were systematically searched from 2008 to February 2021. Screening, data extraction, and quality grading were undertaken by two reviewers. Only trials with a randomised design comparing AGU care and conventional care units were included. Meta-analyses were performed in Review Manager 5.4 and the Grading of Recommendations, Assessment, Development and Evaluations framework was used to assess the certainty of evidence for outcomes reported. The primary outcome measure was incidence of functional decline between baseline two-week prehospital admission status and discharge and at follow-up.

Results

11 trials recruiting 7,496 participants across three countries were included. AGU care was associated with a 23% reduction in functional decline at six-month follow-up (risk ratio (RR) 0.77, 95% confidence interval (CI) 0.64–0.92; moderate certainty evidence), and significant cost savings (mean difference (MD) -538.01USD, 95% CI -571.05USD—-504.96USD; low certainty evidence). No differences were found in functional decline at hospital discharge or at three-month follow-up, length of hospital stay, the likelihood of living at home, mortality, hospital readmission, cognitive function, or patient satisfaction with the index admission.

Conclusion

AGU care improves clinical and process outcomes for older adults admitted to hospital with acute medical complaints. Future research should focus on greater inclusion of clinical and patient reported outcome measures including quality of life. Use of such measures may lead to a greater focus on patient-centered care and service provision priorities.

1081 A COMPARISON OF THE ISAR TOOL AND THE CLINICAL FRAILTY SCALE TO PREDICT MORTALITY AND ED REATTENDANCE IN A COHORT OF ED ATTENDER

Background

Frailty Screening is one method by which we can risk stratify older adults to urgent assessment in the Emergency Department. The ISAR (Identification of Seniors at Risk) and Rockwood Clinical Frailty Scale are two frailty screening tools. We assessed the validity of these tools at predicting adverse outcomes for older adults presenting to the Emergency Department.

Method

This was a prospective cohort study. Patients over 65 were recruited, baseline.

demographics were obtained and a research nurse assessed them using both the Clinical Frailty Scale and ISAR. Patients were assessed by telephone interviews at one month and six months. The outcome measures assessed were mortality, ED re-attendance, hospital readmission, functional decline and institutionalisation.

Results

419 patients were recruited. 53.3% (223) were male with a median age of 76 (IQR = 10). The median ISAR and CFS score was 2,5 respectively at baseline. The mortality rate was 5.4% and rate of ED re-attendance was 16.9% at one month. The relative risk of ED re-admission with an ISAR score &gt;/= 2 more was 1.84 (1.12, 3.02) and CFS &gt; 4 was 1.85 (1.08, 3.16). The ISAR tool &gt;/= 2, had a sensitivity of 74.29 (95% CI = 62.44, 83.99) and specificity of 41.18 (95% CI = 35.90, 46.61) when used as a diagnostic tool for ED re-admission at one month. The CFS &gt; 4 had a sensitivity of 71.43 (95% CI = 57.79, 82.70) and specificity of 45.23 (95% CI = 39.33, 51.23) for the same outcome.

Conclusion

The ISAR tool &gt;/= 2 was the more sensitive at predicting ED reattendance at one month in comparison to the Clinical Frailty Scale. We would advocate using this tool in the ED setting to highlight those at greatest risk of adverse outcomes and those most likely to benefit from Comprehensive Geriatric Assessment.

Stroke Risk Factors, Subtype, and Outcomes in a Multi-Ethnic Stroke Population

Aim We aim to describe differences in stroke risk factors, subtypes and outcomes in a multi-ethnic Irish Stroke population. Gaining an insight into prevalent risk factors and subtypes in ethnic groups may help target prevention efforts. Methods We retrospectively identified patients originally not of Irish ethnicity (ONIE) admitted to the acute stroke unit between 2016 and 2018 through surname recognition (N=44). Country of origin was confirmed on chart review. The presumed native Irish (PNI) patients admitted over the same time frame were used as a comparison group (N=437). Data was collected on stroke subtype, comorbidities, outcomes and socioeconomic factors. Results Patients ONIE made up 9.1% of all stroke unit admissions. Male gender was more common accounting for 33 of 44 (75%) patients ONIE and 251 of 437 (57.4%) PNI (p = 0.02). Overall ONIE were younger than PNI patients (mean age 57.5 [SD 13.0] vs 69.6yr [SD 13.2], p <0.001). Patients ONIE also recorded higher rates of intracranial haemorrhage(ICH) (N = 15 [34.1%] vs N=51 [11.7%], p <0.01). Conclusion Our study demonstrates that stroke patients ONIE have a different stroke subtype and demographic profile compared to Irish patients. Patients ONIE are more likely to be young, male with higher rates of ICH.

209 NEURO-MEDICAL COMPLICATIONS OF STROKE—TRENDS OVER THE DECADES IN AN ACUTE STROKE UNIT

Background

Neuro-medical complications post-stroke are common and often serious [1]. We first described complications in our stroke cohort in 1998 and sought to assess whether the severity and the nature of neuro-medical complications may have changed over time due to changes in presentation and the processes of care [2].

Methods

Analysis of stroke service database, which captures all neuro-medical complications as part of its portal for the Irish National Audit of Stroke (INAS), was completed. The frequency of each of the 19 complications was expressed as the percentage of patients that developed each complication over a certain year and over 5 years. Historical comparison was made with dataset from 1998, which captured six complications.

Results

Data on 1,283 patients presenting over 5 years between 2015–2019 was collected. The median age of all patients was 71 years (Range 21–101). In all, 19 different post-stroke complications were recorded; 48% (n = 622) had post-stroke pain, while 23.85% (n = 306) had cognitive decline. Data on 100 patients from 1998 was compared for a number of common metrics including; 21.82% (n = 275) of patients developed an LRTI in the 2015–2019 cohort compared with 14%(n = 14) in the 1998 cohort (p = 0.09) while 16.29% (n = 209) of patients developed a swallow disorder compared to 21% (n = 21) in 1998 (p = 0.22).

Conclusion

There are high levels of neuro-medical complications in stroke patients. Twenty years has seen extensive investment in hyperacute stroke care yet post-acute care complications did not appear to reduce significantly between this time, albeit with low numbers. Direction of future funding may consider the full spectrum of stroke care.

178 A RETROSPECTIVE EVALUATION OF PROCESS OUTCOMES OF OLDER ADULTS REFERRED TO A COMMUNITY RE-ENABLEMENT TEAM FROM THE EMERGENCY DEPARTMENT

Background

Emergency Departments (ED) are complex and challenging environments to provide care to older adults. There is currently a paucity of high quality methodological research investigating the effectiveness of interventions focused on transitions of care from the ED to primary care services (Hughes et al, 2019). This study aims to evaluate the impact of a collaborative model of care between primary and secondary care services for older adults discharged home following ED index visit.

Methods

This was an observational retrospective study. Participants aged ≥65 years discharged home from the ED of a University Teaching Hospital and referred to a Multidisciplinary Community Intervention Team (MDCIT) were included. Referral pathways were via the OPTIMEND team (Cassarino et al, 2021) and MDCIT, which is a rapid access re-enablement team based in the community and compromises nursing staff, an occupational therapist, physiotherapist, therapy and healthcare assistants. Descriptive statistics were used to profile the baseline characteristics of study participants and to summarise data related to process outcomes. Ethical approval was granted for this study (020/2021).

Results

In the study period, January—December 2020, 54 patients were referred to the MDCIT. The mean age of participants was 80.1 years (SD 8.2), 57% were female, and the most common Manchester Triage System presenting complaint was ‘limb problems’. The median Patient Experience Time within the ED was 7.4 hours (IQR 13.1); 55% of participants were seen in their home within 24 hours of discharge. A mean of 10 interventions were delivered by the MDCIT. A 9.1% incidence rate of 30 day unscheduled hospital readmission was recorded.

Conclusion

Integrated care programmes have been advocated to improve the continuum of care from the ED into the community. This evaluation has demonstrated the feasibility of implementing such a model of care. However, further methodologically robust research is required to advance the evidence base and should also focus on patient outcomes.

56 EFFICACY OF AN ELECTIVE PERIOD OF IN-PATIENT REHABILITATION FOR PATIENTS LIVING WITH PARKINSON’S DISEASE AND FRAILTY: A PILOT STUDY

Background

Frailty and Parkinson’s disease (PD) are more common with increasing age and are associated with syndromes such as falls, immobility, cognitive dysfunction and incontinence. PD may directly cause or co-exist with and compound frailty. A coordinated, multidisciplinary approach to care has been shown to optimize outcomes in both of these conditions. This pilot study aims to examine the short-term effects of an elective two-week in-patient rehabilitation program on frail PD patients’ function, mobility, and self-reported quality of life (QOL).

Methods

This prospective cohort study included all frail PD patients admitted for elective rehabilitation since the program’s conception. Patients included must be able to mobilize independently with or without an aid, or with assistance of one person. They also must be cognitively able to participate in rehabilitation. Patients received consultant-led Comprehensive Geriatric Assessment and attended daily physiotherapy and occupational therapy sessions. Functional outcome and health related QOL measurements were collected on admission and discharge and compared using a paired t-test. Frailty was quantified by the Clinical Frailty Index.

Results

Twelve patients completed the program (58% male). The average age was 79 (range 70–86) and average clinical frailty score was 5.6 indicating mild to moderate frailty. Performance in activities of daily living (Barthel Index: 64 vs 73, p = 0.005), overall mobility (Elderly Mobility Scale: 10.6 vs 12.9, p = 0.004), gait speed (Timed Up and Go: 35 vs 29 seconds, p = 0.05), and balance (Berg Balance Scale: 25 vs 32, p = 0.002) significantly improved from admission to discharge from the program. Health-related QOL also improved (EQ-5D: 44 vs 66, p = 0.004).

Conclusion

Early data suggests that a short elective in-patient rehabilitation program has highly significant benefits for frail PD patients on mobility, performance of activities of daily living, and QOL. Longer term follow-up is required to assess sustainability of these improvements and cost-effectiveness of this intervention.

240 A COMPARISON OF THE ISAR AND THE CLINICAL FRAILTY SCALE TO PREDICT MORTALITY AND ED RE-ATTENDANCE IN OLDER ED ATTENDERS

Background

Frailty Screening is one method by which we can risk stratify older adults to urgent assessment in the Emergency Department. The ISAR (Identification of Seniors at Risk) and Rockwood Clinical Frailty Scale (CFS) are two frailty screening tools. We assessed the validity of these tools at predicting adverse outcomes for older adults presenting to the Emergency Department.

Methods

This was a prospective cohort study. Patients over 65 were recruited, baseline demographics were obtained and a research nurse assessed them using both the CFS and ISAR. Patients were assessed by telephone interviews at one month and six months. The outcome measures assessed were mortality, ED re-attendance, hospital readmission, functional decline and institutionalisation.

Results

419 patients were recruited. 53.3% (223) were male with a median age of 76 (IQR = 10). At baseline, the median ISAR was 2 and CFS was 5. The mortality rate was 5.4% and the rate of ED re-attendance was 16.9% at one month. The relative risk of ED re-admission with an ISAR score ≥ 2 was 1.84 (1.12, 3.02) and CFS &gt; 4 was 1.85 (1.08, 3.16). The ISAR tool ≥2 had a sensitivity of 74% (95% CI = 62.44, 83.99) and specificity of 41% (95% CI = 35.90, 46.61) when used as a diagnostic tool for ED re-admission at one month. The CFS &gt; 4 had a sensitivity of 71% (95% CI = 57.79, 82.70) and specificity of 45% (95% CI = 39.33, 51.23) for ED re-attendance.

Conclusion

The ISAR tool ≥2 was more sensitive at predicting ED reattendance at one month in comparison to the CFS. We advocate to use this tool in the ED setting to highlight those at greatest risk of adverse outcomes and those most likely to benefit from Comprehensive Geriatric Assessment.

Repeat to gene expression ratios in leukemic blast cells can stratify risk prediction in acute myeloid leukemia

BACKGROUND

Repeat elements constitute a large proportion of the human genome and recent evidence indicates that repeat element expression has functional roles in both physiological and pathological states. Specifically for cancer, transcription of endogenous retrotransposons is often suppressed to attenuate an anti-tumor immune response, whereas aberrant expression of heterochromatin-derived satellite RNA has been identified as a tumor driver. These insights demonstrate separate functions for the dysregulation of distinct repeat subclasses in either the attenuation or progression of human solid tumors. For hematopoietic malignancies, such as Acute Myeloid Leukemia (AML), only very few studies on the expression/dysregulation of repeat elements were done.

METHODS

To study the expression of repeat elements in AML, we performed total-RNA sequencing of healthy CD34 + cells and of leukemic blast cells from primary AML patient material. We also developed an integrative bioinformatic approach that can quantify the expression of repeat transcripts from all repeat subclasses (SINE/ALU, LINE, ERV and satellites) in relation to the expression of gene and other non-repeat transcripts (i.e. R/G ratio). This novel approach can be used as an instructive signature for repeat element expression and has been extended to the analysis of poly(A)-RNA sequencing datasets from Blueprint and TCGA consortia that together comprise 120 AML patient samples.

RESULTS

We identified that repeat element expression is generally down-regulated during hematopoietic differentiation and that relative changes in repeat to gene expression can stratify risk prediction of AML patients and correlate with overall survival probabilities. A high R/G ratio identifies AML patient subgroups with a favorable prognosis, whereas a low R/G ratio is prevalent in AML patient subgroups with a poor prognosis.

CONCLUSIONS

We developed an integrative bioinformatic approach that defines a general model for the analysis of repeat element dysregulation in physiological and pathological development. We find that changes in repeat to gene expression (i.e. R/G ratios) correlate with hematopoietic differentiation and can sub-stratify AML patients into low-risk and high-risk subgroups. Thus, the definition of a R/G ratio can serve as a valuable biomarker for AML and could also provide insights into differential patient response to epigenetic drug treatment.

Clinical findings, neurological manifestations and survival of dogs with insulinoma: 116 cases (2009-2020)

OBJECTIVES

To review the clinical findings and outcome in dogs diagnosed with insulinoma, and to assess which factors are predictors of overall survival. Additionally, to describe the neurological manifestations of this population and their correlation with survival.

MATERIALS AND METHODS

Retrospective multicentric study of canine insulinoma cases (2009 to 2020). Signalment, clinical history, neurological examination, diagnostic findings, treatment and outcome were obtained from clinical records. Univariate and multivariate analyses were used to compare the overall survival.

RESULTS

One hundred and sixteen cases were included. Median duration of clinical signs before presentation was 1.5 months. The most common presenting clinical signs were weakness (59.5%), epileptic seizures (33.6%) and changes in consciousness or behaviour (27.6%). Three dogs were suspected to have paroxysmal dyskinesia. Thirty-two dogs had an abnormal neurological examination, most commonly showing obtundation (28.1%), decreased withdrawal reflexes (21.9%) and absent menace response (18.8%). Overall survival for dogs undergoing surgery (20 months) was significantly longer than in medically treated (8 months; adjusted hazard ratio: 0.33; 95% confidence interval: 0.18, 0.59). Presence of metastases was the only other variable associated with prognosis (adjusted hazard ratio 1.72; 95% confidence interval: 1.02, 2.91).

CLINICAL SIGNIFICANCE

Clinical signs of canine insulinoma are vague and non-specific. Weakness, epileptic seizures and changes in mentation or behaviour were the most commonly reported. Obtunded mentation and forebrain neurolocalisation were the main neurological manifestations. Dogs undergoing surgery had a longer overall survival compared to medically treated cases, and dogs with metastasis had a shorter overall survival regardless of treatment modality. Abnormalities in the neurological examination did not correlate with prognosis.

33 Diagnostic Test Accuracy of the 4AT for Delirium Detection: Systematic Review and Meta-Analysis

Introduction

Detection of delirium in hospitalised older adults is recommended in national and international guidelines. The 4 ‘A’s Test (4AT; www.the4AT.com) is a short (&lt;2 min) instrument for delirium detection that is used internationally as a standard tool in clinical practice. We performed a systematic review and meta-analysis of diagnostic test accuracy of the 4AT for delirium detection.

Methods

We searched the following electronic databases through Ovid: MEDLINE, Embase, and PsycINFO. Additional databases were searched: CINAHL (EBSCOhost), clinicaltrials.gov and Cochrane Central Register of Controlled Trials from 2011 (4AT publication) until 21 December 2019. Inclusion criteria: older adults (≥65) across any setting of care except critical care; validation study of the 4AT against a delirium reference standard (standard diagnostic criteria or validated tool). Two reviewers independently screened abstracts and papers and performed the data extraction. Pooled estimates of sensitivity and specificity were generated from a bivariate random effects model.

Results

17 studies (n = 3,701 observations) were included. Various settings including acute medicine, surgery, stroke wards and the emergency department were represented. The overall prevalence of delirium was 24.2% (95% CI 17.8–32.1%; range 10.5–61.9%). The pooled sensitivity was 0.88 (95% CI 0.80–0.93) and the pooled specificity was 0.88 (95% CI 0.82–0.92). The methodological quality of studies was mostly good.

Conclusions

The 4AT is now supported by a substantial evidence base comparable to other well-studied tools such as the Confusion Assessment Method (CAM). The strong pooled sensitivity and specificity findings for the 4AT in this meta-analysis along with its brevity and lack of need for specific training provide support for its use as an effective assessment tool for delirium.

56 Ageism in Myelodysplastic Syndrome

Background

Myelodysplastic Syndromes (MDS) are a group of haematological disorders which are common in older people and can be amenable to treatment. Ageism has previously been identified in studies of treatment for conditions affecting older people.

Objectives

To assess for the presence of ageism in studies of treatment for MDS.

Design

A review of the Cochrane Library of Systematic Reviews.

Setting

Desk-based.

Methods

Systematic reviews were analysed to determine: use of age as an exclusion criteria in randomized-control trials (RCTs); the comparison of ages of patients in RCTs to that of the median age of patients with MDS; exclusion of patients from RCTs on the basis of dementia or other conditions associated with ageing.

Results

17 reviews were identified, 2 of which were suitable for analysis. The two remaining systematic reviews reported data on 13 RCTs—of which 2 did not report age. The median age of all patients was 68. Three RCTs used a maximum age limit for therapy—one of which was lower than the median age of diagnosis of MDS. More recent studies tended to include older patients. No studies excluded patients on the basis of cognitive status.

Conclusion

There was some evidence of ageism identified in studies of treatment for MDS. There was limited data available in the Cochrane database of Systematic Reviews, which may itself be suggestive of ageism in such reviews.

Treatment of allergic rhinitis during and outside the pollen season using mobile technology. A MASK study

Background

The analysis of mobile health (mHealth) data has generated innovative insights into improving allergic rhinitis control, but additive information is needed. A cross-sectional real-world observational study was undertaken in 17 European countries during and outside the estimated pollen season. The aim was to collect novel information including the phenotypic characteristics of the users.

Methods

The Allergy Diary–MASK-air–mobile phone app, freely available via Google Play and App, was used to collect the data of daily visual analogue scales (VASs) for overall allergic symptoms and medication use. Fluticasone Furoate (FF), Mometasone Furoate (MF), Azelastine Fluticasone Proprionate combination (MPAzeFlu) and eight oral H1-antihistamines were studied. Phenotypic characteristics were recorded at entry. The ARIA severity score was derived from entry data. This was an a priori planned analysis.

Results

9037 users filled in 70,286 days of VAS in 2016, 2017 and 2018. The ARIA severity score was lower outside than during the pollen season. Severity was similar for all treatment groups during the pollen season, and lower in the MPAzeFlu group outside the pollen season. Days with MPAzeFlu had lower VAS levels and a higher frequency of monotherapy than the other treatments during the season. Outside the season, days with MPAzeFlu also had a higher frequency of monotherapy. The number of reported days was significantly higher with MPAzeFlu during and outside the season than with MF, FF or oral H1-antihistamines.

Conclusions

This study shows that the overall efficacy of treatments is similar during and outside the pollen season and indicates that medications are similarly effective during the year.

Optimal Timing of CT Scanning in the Rapid Access Lung Cancer Clinic

Aims To investigate whether a ‘CT first’ approach to Rapid Access Lung Cancer Clinic (RALC) review could be feasible in an Irish context. Methods A retrospective review of our institution’s Lung Cancer Database was performed. All RALC first attendances from 2012-2018 were identified. Timing of CT was assessed as well as CT imaging findings. Results Total first attendances in this period were 2372, of whom 91% had CT thorax as part of their evaluation. 866 patients (37%) were diagnosed with lung cancer, all had an abnormal CT. 1290 patients (54%) underwent CT but did not have lung cancer after clinical work up. 34% of patients diagnosed with Lung Cancer had their CT scan post RALC. Time to diagnosis was longer in those who had post RALC CT (34.5 versus 21 days) Conclusion CT scanning plays a vital role in the RALC pathway. Initial delays in obtaining CT can result in delayed time to diagnosis. These findings warrant close consideration when devising future national lung cancer policy.

Correlation between work impairment, scores of rhinitis severity and asthma using the MASK-air® App

BACKGROUND

In allergic rhinitis, a relevant outcome providing information on the effectiveness of interventions is needed. In MASK-air (Mobile Airways Sentinel Network), a visual analogue scale (VAS) for work is used as a relevant outcome. This study aimed to assess the performance of the work VAS work by comparing VAS work with other VAS measurements and symptom-medication scores obtained concurrently.

METHODS

All consecutive MASK-air users in 23 countries from 1 June 2016 to 31 October 2018 were included (14 189 users; 205 904 days). Geolocalized users self-assessed daily symptom control using the touchscreen functionality on their smart phone to click on VAS scores (ranging from 0 to 100) for overall symptoms (global), nose, eyes, asthma and work. Two symptom-medication scores were used: the modified EAACI CSMS score and the MASK control score for rhinitis. To assess data quality, the intra-individual response variability (IRV) index was calculated.

RESULTS

A strong correlation was observed between VAS work and other VAS. The highest levels for correlation with VAS work and variance explained in VAS work were found with VAS global, followed by VAS nose, eye and asthma. In comparison with VAS global, the mCSMS and MASK control score showed a lower correlation with VAS work. Results are unlikely to be explained by a low quality of data arising from repeated VAS measures.

CONCLUSIONS

VAS work correlates with other outcomes (VAS global, nose, eye and asthma) but less well with a symptom-medication score. VAS work should be considered as a potentially useful AR outcome in intervention studies.

European Position Paper on Rhinosinusitis and Nasal Polyps 2020

The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.

Guidance to 2018 good practice: ARIA digitally-enabled, integrated, person-centred care for rhinitis and asthma

Aims

Mobile Airways Sentinel NetworK (MASK) belongs to the Fondation Partenariale MACVIA-LR of Montpellier, France and aims to provide an active and healthy life to rhinitis sufferers and to those with asthma multimorbidity across the life cycle, whatever their gender or socio-economic status, in order to reduce health and social inequities incurred by the disease and to improve the digital transformation of health and care. The ultimate goal is to change the management strategy in chronic diseases.

Methods

MASK implements ICT technologies for individualized and predictive medicine to develop novel care pathways by a multi-disciplinary group centred around the patients.

Stakeholders

Include patients, health care professionals (pharmacists and physicians), authorities, patient’s associations, private and public sectors.

Results

MASK is deployed in 23 countries and 17 languages. 26,000 users have registered.

EU grants (2018)

MASK is participating in EU projects (POLLAR: impact of air POLLution in Asthma and Rhinitis, EIT Health, DigitalHealthEurope, Euriphi and Vigour).

Lessons learnt

(i) Adherence to treatment is the major problem of allergic disease, (ii) Self-management strategies should be considerably expanded (behavioural), (iii) Change management is essential in allergic diseases, (iv) Education strategies should be reconsidered using a patient-centred approach and (v) Lessons learnt for allergic diseases can be expanded to chronic diseases.

MASK 2017: ARIA digitally-enabled, integrated, person-centred care for rhinitis and asthma multimorbidity using real-world-evidence

mHealth, such as apps running on consumer smart devices is becoming increasingly popular and has the potential to profoundly affect healthcare and health outcomes. However, it may be disruptive and results achieved are not always reaching the goals. Allergic Rhinitis and its Impact on Asthma (ARIA) has evolved from a guideline using the best evidence-based approach to care pathways suited to real-life using mobile technology in allergic rhinitis (AR) and asthma multimorbidity. Patients largely use over-the-counter medications dispensed in pharmacies. Shared decision making centered around the patient and based on self-management should be the norm. Mobile Airways Sentinel networK (MASK), the Phase 3 ARIA initiative, is based on the freely available MASK app (the Allergy Diary, Android and iOS platforms). MASK is available in 16 languages and deployed in 23 countries. The present paper provides an overview of the methods used in MASK and the key results obtained to date. These include a novel phenotypic characterization of the patients, confirmation of the impact of allergic rhinitis on work productivity and treatment patterns in real life. Most patients appear to self-medicate, are often non-adherent and do not follow guidelines. Moreover, the Allergy Diary is able to distinguish between AR medications. The potential usefulness of MASK will be further explored by POLLAR (Impact of Air Pollution on Asthma and Rhinitis), a new Horizon 2020 project using the Allergy Diary.

mySinusitisCoach: patient empowerment in chronic rhinosinusitis using mobile technology

Mobile health technology is emerging to take a prominent position in the management of chronic diseases. These technologies aim at enhancing patient empowerment via education and self-management. To date, of all the different apps available for patients with sinus disease, none were developed by medical experts dealing with chronic rhinosinusitis (CRS). The European Forum for Research and Education in Allergy and Airway diseases (EUFOREA) has undertaken a multi-stakeholder approach for designing, developing and implementing a tool to support CRS patients in monitoring their symptoms and to provide patients with a digital support platform containing reliable medical information about their disease and treatment options. mySinusitisCoach has been developed by medical experts dealing with CRS in close collaboration with patients, primary care physicians and community pharmacists, meeting the needs of both patients and health care providers. From a research perspective, the generation of real life data will help to validate clinical studies, patient stratification and improve understanding of the socio-economic impact of CRS, thereby paving the way for better treatment strategies.

Treatment of allergic rhinitis using mobile technology with real-world data: The MASK observational pilot study

BACKGROUND

Large observational implementation studies are needed to triangulate the findings from randomized control trials as they reflect "real-world" everyday practice. In a pilot study, we attempted to provide additional and complementary insights on the real-life treatment of allergic rhinitis (AR) using mobile technology.

METHODS

A mobile phone app (Allergy Diary, freely available in Google Play and Apple App stores) collects the data of daily visual analog scales (VAS) for (i) overall allergic symptoms, (ii) nasal, ocular, and asthma symptoms, (iii) work, as well as (iv) medication use using a treatment scroll list including all medications (prescribed and over the counter (OTC)) for rhinitis customized for 15 countries.

RESULTS

A total of 2871 users filled in 17 091 days of VAS in 2015 and 2016. Medications were reported for 9634 days. The assessment of days appeared to be more informative than the course of the treatment as, in real life, patients do not necessarily use treatment on a daily basis; rather, they appear to increase treatment use with the loss of symptom control. The Allergy Diary allowed differentiation between treatments within or between classes (intranasal corticosteroid use containing medications and oral H1-antihistamines). The control of days differed between no [best control], single, or multiple treatments (worst control).

CONCLUSIONS

This study confirms the usefulness of the Allergy Diary in accessing and assessing everyday use and practice in AR. This pilot observational study uses a very simple assessment (VAS) on a mobile phone, shows novel findings, and generates new hypotheses.

Promoting and achieving excellence in the delivery of Integrated Allergy Care: the European Academy of Allergy & Clinical Immunology competencies for allied health professionals working in allergy

The multi-disciplinary team approach is an effective model for patient care. Allied health professionals (AHPs) are an important part of such teams, bringing specific knowledge and skills related to the target patient population. The AHPs most often involved in allergy care are nurses and dietitians. Nurses are often involved in the care of patients with all types of allergy and also with asthma, whilst allergy-specialist dietitians provide vital nutritional and dietary support for the diagnosis and management of food allergy. There are many other AHPs who have a role to play in allergy care, including physiotherapists, psychologists, pharmacists and speech therapists, and their involvement is likely to develop as allergy care becomes more rooted in the community. With the development of multi-professional teams comes the requirement for disease-specific knowledge and skill sets, with all allergy team members required to have baseline knowledge and competency of the condition being managed. Whilst some competencies for AHPs practising in other disease states have been published, none are available for allergic disease against which AHPs can be benchmarked. The European Academy of Allergy & Clinical Immunology (EAACI) recognised this need, and supported the establishment of a Task Force to develop allergy-focussed competencies for AHPs. The varied skills, expertise and professional background of the Task Force members enabled the creation of a set of allergy competencies relevant to all AHPs working in allergy. It is recognised that the training and allergy expertise of AHPs, and their role within the allergy setting, will vary considerably depending on the country. However, it is important for patient care, that all AHP involved in allergy services have access to training, of a sufficiently high enough level to be aspirational and enable the continued growth and development of a wide range of allergy services, given the increasing need. The EAACI competencies will provide an important benchmark for allergy knowledge and skills against which education and training can be designed and health care professionals can subsequently be measured. However, more importantly, the EAACI AHP allergy competencies will enable the development and reach of specialist allergy services, with allergy-specialist AHPs undertaking key roles, especially in the community care setting.

Daily allergic multimorbidity in rhinitis using mobile technology: A novel concept of the MASK study

BACKGROUND

Multimorbidity in allergic airway diseases is well known, but no data exist about the daily dynamics of symptoms and their impact on work. To better understand this, we aimed to assess the presence and control of daily allergic multimorbidity (asthma, conjunctivitis, rhinitis) and its impact on work productivity using a mobile technology, the Allergy Diary.

METHODS

We undertook a 1-year prospective observational study in which 4 210 users and 32 585 days were monitored in 19 countries. Five visual analogue scales (VAS) assessed the daily burden of the disease (i.e., global evaluation, nose, eyes, asthma and work). Visual analogue scale levels <20/100 were categorized as "Low" burden and VAS levels ≥50/100 as "High" burden.

RESULTS

Visual analogue scales global measured levels assessing the global control of the allergic disease were significantly associated with allergic multimorbidity. Eight hypothesis-driven patterns were defined based on "Low" and "High" VAS levels. There were <0.2% days of Rhinitis Low and Asthma High or Conjunctivitis High patterns. There were 5.9% days with a Rhinitis High-Asthma Low pattern. There were 1.7% days with a Rhinitis High-Asthma High-Conjunctivitis Low pattern. A novel Rhinitis High-Asthma High-Conjunctivitis High pattern was identified in 2.9% days and had the greatest impact on uncontrolled VAS global measured and impaired work productivity. Work productivity was significantly correlated with VAS global measured levels.

CONCLUSIONS

In a novel approach examining daily symptoms with mobile technology, we found considerable intra-individual variability of allergic multimorbidity including a previously unrecognized extreme pattern of uncontrolled multimorbidity.

Geolocation with respect to personal privacy for the Allergy Diary app - a MASK study

Background

Collecting data on the localization of users is a key issue for the MASK (Mobile Airways Sentinel networK: the Allergy Diary) App. Data anonymization is a method of sanitization for privacy. The European Commission's Article 29 Working Party stated that geolocation information is personal data.To assess geolocation using the MASK method and to compare two anonymization methods in the MASK database to find an optimal privacy method.

Methods

Geolocation was studied for all people who used the Allergy Diary App from December 2015 to November 2017 and who reported medical outcomes. Two different anonymization methods have been evaluated: Noise addition (randomization) and k-anonymity (generalization).

Results

Ninety-three thousand one hundred and sixteen days of VAS were collected from 8535 users and 54,500 (58.5%) were geolocalized, corresponding to 5428 users. Noise addition was found to be less accurate than k-anonymity using MASK data to protect the users' life privacy.

Discussion

k-anonymity is an acceptable method for the anonymization of MASK data and results can be used for other databases.
