A Physiotherapy-Led Transition to Home Intervention for Older Adults Following Emergency Department Discharge: A Pilot Feasibility Randomised Controlled Trial (ED PLUS).

Background: Older adults frequently attend the emergency department (ED) and experience high rates of subsequent adverse outcomes 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. Our aim was to evaluate the feasibility of a physiotherapy-led integrated care intervention for older adults discharged from the ED (ED PLUS). Patients and Methods: Older adults presenting to the ED of a university teaching hospital 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. 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 home. Feasibility and acceptability were assessed quantitatively and qualitatively. All clinical and process outcomes were assessed by a research nurse blinded to group allocation. Data analyses were primarily descriptive. Results: Twenty-nine participants were recruited indicating a 67% recruitment rate. At 6 months, there was 100% retention in the usual care group, 88% in the CGA group and 90% in the ED PLUS group. ED PLUS participants expressed positive feedback, and there was a trend towards improved function and quality of life and less ED revisits and unscheduled hospitalisations in the ED PLUS group. Conclusion: ED PLUS bridges the transition of care between the index visit to the ED and the community and is feasible using systematic recruitment strategies. Despite recruitment challenges in the context of COVID-19, the intervention was successfully delivered and well received by participants. There was a lower incidence of functional decline and improved quality of life in the ED PLUS group. Trial Registration: The trial was registered in Clinical Trials Protocols and Results System as of 21st July 2021, with registration number NCT04983602.

Clinical Frailty Scale as a predictor of adverse outcomes following aortic valve replacement: a systematic review and meta-analysis.

OBJECTIVES: Assessment of frailty prior to aortic valve intervention is recommended in European and North American valvular heart disease guidelines. However, there is a lack of consensus on how it is best measured. The Clinical Frailty Scale (CFS) is a well-validated measure of frailty that is relatively quick to calculate. This meta-analysis sought to examine whether the CFS predicts mortality and morbidity following either transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR). METHODS: Nine electronic databases were searched systematically for data on clinical outcomes post-TAVI/SAVR, where patients had undergone preoperative frailty assessment using the CFS. The primary endpoint was 12-month mortality. TAVI and SAVR data were assessed and reported separately. For each individual study, the incidence of adverse outcomes was extracted according to a CFS score of 5-9 (ie, frail) versus 1-4 (ie, non-frail), with meta-analysis performed using a random effects model. RESULTS: Of 2612 records screened, nine were included in the review (five TAVI, three SAVR and one which included both interventions). Among 4923 TAVI patients, meta-analysis showed 12-month mortality rates of 19.1% for the frail cohort versus 9.8% for the non-frail cohort (RR 2.53 (1.63 to 3.95), p<0.001, I2=83%). For the smaller cohort of SAVR patients (n=454), mortality rates were 20.3% versus 3.9% for the frail and non-frail cohorts, respectively (RR 5.08 (2.31 to 11.15), p<0.001, I2=5%). CONCLUSIONS: Frailty, as determined by the CFS, was associated with an increased mortality risk in the 12 months following either TAVI or SAVR. These data would support its use in the preoperative assessment of elderly patients undergoing aortic valve interventions.

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. We assessed the validity of the Identification of Seniors at Risk (ISAR), Clinical Frailty Scale (CFS), Programme on Research for Integrating Services for the Maintenance of Autonomy seven item questionnaire (PRISMA-7) and InterRAI-ED at predicting adverse outcomes at 30 days and 6 months amongst older adults presenting to the Emergency Department (ED). METHODS: a prospective cohort study of adults ≥65 years who presented to the ED was conducted. The ISAR, CFS, PRISMA-7 and InterRAI-ED were assessed. Blinded follow-up telephone interviews were completed at 30 days and 6 months to assess the incidence of mortality, ED re-attendance, hospital readmission, functional decline and nursing home admission. The sensitivity, specificity, negative predictive value and positive predictive value of the screening tools were calculated using 2 × 2 tables. RESULTS: a total of 419 patients were recruited; 47% female with a mean age of 76.9 (Standard deviation = 7.2). The prevalence of frailty varied across the tools (CFS 57% versus InterRAI-ED 70%). At 30 days, the mortality rate was 5.1%, ED re-attendance 18.1%, hospital readmission 14%, functional decline 47.6% and nursing home admission 7.1%. All tools had a high sensitivity and positive predictive value for predicting adverse outcomes. CONCLUSION: older adults who screened positive for frailty were at significantly increased risk of experiencing an adverse outcome at 30 days with the ISAR being the most sensitive tool. We would recommend the implementation of the ISAR in the ED setting to support clinicians in identifying older adults most likely to benefit from specialised geriatric assessment and intervention.

Topical bromfenac as adjunctive treatment with intravitreal ranibizumab for diabetic macular edema.

PURPOSE: To determine the safety and efficacy of adding topical bromfenac 0.09% in the treatment of diabetic macular edema. METHODS: Seventy patients (70 eyes) with center involved diabetic macular edema with macular thickness (300-500 µm) were included. Patients were divided randomly into two groups: 35 eyes in each group. Both groups were treated with intravitreal ranibizumab monthly for three consecutive months. Bromfenac 0.09% eye drops twice daily was added to the treatment of study group for six months from commencement of treatment. The efficacy of topical bromfenac was evaluated by comparing both groups through follow-up period as regards to visual acuity, central and average thickness and the need for re-injection. RESULTS: Patients treated with topical bromfenac in addition to intravitreal ranibizumab revealed significant improvement in visual acuity, more reduction in central and average macular thickness and less tendency to need reinjection compared to those treated with ranibizumab alone (p 0.013, p 0.010 and p 0.022, respectively). No side effects was encountered with the use of topical bromfenac. CONCLUSION: Topical bromfenac 0.09% twice a day could enhance and sustain the efficacy of intravitreal ranibizumab in the treatment of diabetic macular edema without increasing the incidence of corneal side effects.

Radioembolization for Intermediate-Stage Hepatocellular Carcinoma Maintains Liver Function and Permits Systemic Therapy at Progression.

PURPOSE: To assess the liver function trends in patients with intermediate-stage (Barcelona Clinic Liver Cancer [BCLC] Stage B) hepatocellular carcinoma (HCC) who underwent yttrium-90 transarterial radioembolization (TARE) in response to a growing concern that liver-directed therapies negatively affect liver function and prevent patients with HCC from systemic therapy candidacy. MATERIALS AND METHODS: An HCC/TARE database (2004-2017) was retrospectively reviewed. Patients with BCLC Stage B/Child-Pugh (CP)-A HCC with laboratory test and imaging data at baseline and for at least 1 month after TARE were included. Follow-ups were at 3-month intervals. CP stage was assessed at each time point. End points included time to persistent CP-B status, time to CP-C status, and median overall survival (OS). Time-to-end point analyses were performed using the Kaplan-Meier method. RESULTS: Seventy-four patients (80% men, with a mean age of 63 years) with mostly (62%) bilobar disease underwent 186 TARE treatments (median, 2; range, 1-8). The median time to second TARE was 2.3 months (range, 1.7-6.4 months), and the median times to third and fourth TAREs were 11.7 months (range, 7.5-15 months) and 17.3 months (range, 11.5-23.1 months), respectively. Forty-three (58%) patients developed persistent CP-B HCC at a median time of 15.4 months (95% CI, 9.2-25.3 months); 17 (23%) patients developed CP-C HCC at a median time of 87.2 months (95% CI, 39.8-136.1 months). The median OS censored to transplantation was 30.4 months (95% CI, 22.7-37.4 months). On univariate and multivariate analyses, baseline albumin was a significant prognosticator of OS, whereas baseline albumin and bilirubin were significant prognosticators of time to persistent CP-B HCC and time to CP-C HCC. CONCLUSIONS: In patients with CP-A HCC who underwent TARE for BCLC Stage B HCC, the median time to persistent CP-B HCC was 15.4 months. These findings indicate that patients would be candidates for systemic therapy at progression if indicated.

A physiotherapy-led transition to home intervention for older adults following Emergency Department discharge: a pilot feasibility randomised controlled trial.

INTRODUCTION: 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. 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 6-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: Twenty-nine 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. DISCUSSION: 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 6-month outcomes.

Medium-Term Outcomes of Antegrade Continent Enema (ACE): Cairo University Specialized Pediatric Hospital (CUSPH) Experience.

AIM OF THE STUDY: To assess the medium-term outcomes of ACE in children with fecal incontinence (FI). METHOD: Eligible children were recruited from the colorectal clinic between December 2016 and January 2020 and were followed prospectively for 2-6 years. A series of questionnaires were used to assess QOL, patients and parent satisfaction, and to assess the outcomes of the ACE. RESULT: 24 children aged 6-12 years (mean age 8.17 ± 1.95), including 18 males (75%) and 6 females (25% were studied. Cases included anorectal malformations (45.83%)., Hirschsprung disease (25%), neural tube defects (16.66%), sacrococcygeal teratoma (4.16%), and intractable pseudoincontinence (8.33%). QOL improved from (3) [3 -3] to (16) [16-16],p < 0.05. Fecal incontinence index showed significant improvement: 20 [20-20] versus 3 [0-4],p < 0.05. Bowel symptoms demonstrated improvement in the ability to decide when to pass stools and a decrease in soiling. Stooling survey showed lower scores representing better outcome. ACE questionnaire showed that the range of irrigation volumes used by parents is wide, and that all families recommend the ACE for children with similar condition. Postoperative complications were stenosis (16.66%), stomal prolapse (12.5%), leakage (4.16%), and false passage (4.16%). Satisfaction questionnaire showed a median score of 9 (range, 5-10). CONCLUSION: ACE is an effective method to keep the child with FI clean, more socially active, and with a better QOL and FII in the medium-term. The reported complications were stenosis, false passage, and leakage. ACE mucosa prolapse is a novel complication picked up on medium-term follow up.

Uterine Fibroid Embolization or Myomectomy: How Much Marketing Is Enough? Comparative Analysis of Public Search Trends in Google and Medical Publications in PubMed.

To compare public popularity and volume of scientific publications regarding uterine fibroid embolization (UFE) and myomectomy. Google Trends and PubMed data were queried to assess temporal variations in online public search volumes and number of research publications for UFE and myomectomy. Time series analysis was used to identify meaningful temporal trends and forecast a future trend. Compared with UFE, myomectomy had significantly higher volumes of public online search and research publications, with an increasing trend over time (P < .0001). The forecasting models predicted a continuing increase in both public search volumes and number of research publications for myomectomy and static future trends in these metrics for UFE. This study signals significantly lower public popularity and research efforts for UFE compared with myomectomy for uterine fibroids. More effective marketing strategies and further research support will be needed to fill this gap.

A cross-sectional survey of doctors' views on flexible postgraduate physician training in Ireland.

Recruitment and retention of doctors is a priority for the Irish healthcare service, with many leaving to work in regions with more favourable conditions. Aligning flexible training options with other jurisdictions may be an effective means of improving working conditions. We sought to assess possible improvements to the existing system and to review barriers to flexible training. We carried out a survey using 'Survey Monkey' and disseminated it to 1557 basic specialist (BST) and higher specialist trainee (HST) doctors of the Institute of Medicine, 3500 members of the Irish Medical Organisation (IMO), and across social media. There were 854 respondents; 303 (35.5%) BST, 352 (41.2%) HST, 125 (14.6%) non-training doctors, unknown, n = 74. The response rate was approximately 15-23%. Non-consultant doctors identified a preference for access to flexible training (n = 849, 99.4%), with 82.2 of doctors reporting that they would consider applying (n = 702). Most (92.4%) considered the current provision of 16 whole-time equivalent positions as inadequate (n = 789). Of doctors who would not apply for flexible training, themes identified included a perceived negative impact on their career, not meeting eligibility criteria, prolonged training, and salary implications. Suggestions for improving the system included expanding the number of places available, removing eligibility criteria, job sharing options, and the provision of regional training schemes. Access to flexible training should be a priority for the healthcare service, which may enhance recruitment and retention. A majority of our sample of non-consultant doctors identified a preference for access to flexible training options.

Effect of Light Quality and Media Components on Shoot Growth, Rutin, and Quercetin Production from Common Buckwheat.

Common buckwheat (Fagopyrum esculentum Moench) seeds are important nutritious grains that are widely spread in several human food products and livestock feed. Their health benefits are mainly due to their bioactive phenolic compounds, especially rutin and quercetin, which have a positive impact on heart health, weight loss, and diabetes management. In this study, we evaluated different media and light treatments for the in vitro cultures of common buckwheat (CB) in order to find the most optimum one producing the highest yield with the highest purity of these compounds. The subcultured treated samples included in this study were shoots, leaves, stems, hairy roots, and calli. From the several treated samples and under different light stress conditions, the best production was achieved by growing the shoots of common buckwheat in hormone-free media containing activated charcoal and exposing to blue light, attaining 4.3 mg and 7.0 mg/g of extracts of rutin and quercetin, respectively, compared to 3.7 mg of rutin/g of extract and traces of quercetin in the seeds of CB. Continuous multiplication of CB shoots in the media containing charcoal and different concentrations of kinetin produced an extract with 161 mg/g of rutin and 26 mg/g of quercetin with an almost 20-fold increase in rutin content. The rutin content under these conditions reached up to 16% w/w of the extract. The hairy root cultures of the leaves exposed to red light showed a significantly high yield of quercetin attaining 10 mg/g of extract. Large-scale production of CB shootlets under the best conditions were carried out, which enabled the isolation of pure quercetin and rutin using a simple chromatographic procedure. The identity and purity of the isolated compounds were confirmed through NMR and HPLC analyses.

Impact of Portal Hypertension on Adverse Events after Splenic Arterial Aneurysm Embolization.

PURPOSE: To evaluate the outcomes of splenic artery aneurysm (SAA) embolization and compare adverse event (AE) rates after embolization in patients with and without portal hypertension (PHTN). MATERIALS AND METHODS: A retrospective review of all patients who underwent embolization of SAAs at 2 institutions was performed (34 patients from institution 1 and 7 patients from institution 2). Baseline demographic characteristics, preprocedural imaging, procedural techniques, and postprocedural outcomes were evaluated. Thirty-day postprocedural severe and life-threatening AEs were evaluated using the Society of Interventional Radiology guidelines. Thirty-day mortality and readmission rates were also evaluated. t test, χ2 test, and/or Fisher exact test were used for the statistical analysis. RESULTS: There was no statistically significant difference between patients with and without PHTN in the location, number, and size of SAA(s). All procedures were technically successful. There were 13 (32%) patients with and 28 (68%) patients without PHTN. The 30-day mortality rate (31% vs 0%; P = .007), readmission rates (61% vs 7%; P < .001), and severe/life-threatening AE rates (69% vs 0%; P < .001) were significantly higher in patients with PHTN than in those without PHTN. CONCLUSIONS: There was a significantly higher mortality and severe/life-threatening AE rate in patients with PHTN than in those without PHTN. SAAs in patients with PHTN need to be managed very cautiously, given the risk of severe/life-threatening AEs after embolization.

Yttrium-90 Radioembolization of Unresectable Intrahepatic Cholangiocarcinoma: Long-Term Follow-up for a 136-Patient Cohort.

PURPOSE: Unresectable intrahepatic cholangiocarcinoma (ICC) signifies a poor prognosis with limited treatment options beyond systemic chemotherapy. This study's purpose was to evaluate the safety, efficacy, and potential for downstaging to resection of yttrium-90 (Y90) radioembolization for treatment of unresectable ICC. MATERIALS AND METHODS: From 2004 to 2020, 136 patients with unresectable ICC were treated with radioembolization at a single institution. Retrospective review was performed of a prospectively collected database. Outcomes were (1) biochemical and clinical toxicities, (2) local tumor response, (3) time to progression, and (4) overall survival (OS) after Y90. Univariate/multivariate survival analyses were performed. A subgroup analysis was performed to calculate post-resection recurrence and OS in patients downstaged to resection after Y90. RESULTS: Grade 3+ clinical and biochemical toxicities were 7.6% (n = 10) and 4.9% (n = 6), respectively. Best index lesion response was complete response in 2 (1.5%), partial response in 42 (32.1%), stable disease in 82 (62.6%), and progressive disease in 5 (3.8%) patients. Median OS was 14.2 months. Solitary tumor (P < 0.001), absence of vascular involvement (P = 0.009), and higher serum albumin (P < 0.001) were independently associated with improved OS. Eleven patients (8.1%) were downstaged to resection and 2 patients (1.5%) were bridged to transplant. R0-resection was achieved in 8/11 (72.7%). Post-resection median recurrence and OS were 26.3 months and 39.9 months, respectively. CONCLUSION: Y90 has an acceptable safety profile and high local disease control rates for the treatment of unresectable ICC. Downstaging to resection with > 3 years survival supports the therapeutic role of Y90 for unresectable ICC. LEVEL OF EVIDENCE: Level 3, single-arm single-center cohort study.

Yttrium-90 for colorectal liver metastasis - the promising role of radiation segmentectomy as an alternative local cure.

The majority of patients with metastatic colorectal cancer (CRC) to the liver are not amenable to curative-intent surgery or thermal ablation; there is a need for alternative locoregional therapies to control oligometastatic liver disease. Sequential lobar Yttrium-90 (Y90) radioembolization has demonstrated favorable results in the salvage setting for CRC patients with liver only or liver-dominant metastatic disease, but the role of Y90 in earlier-stage disease has not shown to be as promising. Recently, radiation segmentectomy, the super selective delivery of high (ablative) dose Y90 microspheres, has been introduced as a novel approach for patients with unresectable hepatocellular carcinoma. This review provides an overview of the current role of Y90 radioembolization for CRC patients with metastasis to the liver, with specific focus on the evolving application of radiation segmentectomy for patients with limited hepatic metastases from colorectal cancer.

Rockwood Clinical Frailty Scale as a predictor of adverse outcomes among older adults undergoing aortic valve replacement: a protocol for a systematic review.

INTRODUCTION: Frailty is associated with adverse outcomes relating to cardiac procedures. It has been proposed that frailty scoring should be included in the preoperative assessment of patients undergoing aortic valve replacement. We aim to examine the Rockwood Clinical Frailty Scale (CFS), as a predictor of adverse outcomes following aortic valve replacement. METHODS AND ANALYSIS: Prospective and retrospective cohort studies and randomised controlled trials assessing both the preoperative frailty status (as per the CFS) and incidence of adverse outcomes among older adults undergoing either surgical aortic valve replacement or transcatheter aortic valve replacement will be included. Adverse outcomes will include mortality and periprocedural complications, as well as a composite of 30-day complications. A search will be conducted from 2005 to present using a prespecified search strategy. Studies will be screened for inclusion by two reviewers, with methodological quality assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Relative risk ratios with 95% CIs will be generated for each outcome of interest, comparing frail with non-frail groups. Data will be plotted on forest plots where applicable. The quality of the evidence will be determined using the Grading of Recommendations, Assessment, Development and Evaluation tool. ETHICS AND DISSEMINATION: Ethical approval is not required for this study as no primary data will be collected. We will publish the review in a peer-reviewed journal on completion. PROSPERO REGISTRATION NUMBER: CRD42020213757.

Clinical characteristics of two groups commonly referred to an Irish hypertension service-patients with resistant hypertension and young adults with hypertension.

BACKGROUND: The management of hypertension is primarily performed in primary care settings in many health systems. However, two groups of patients often require specialist input: patients with resistant hypertension (RH) and young adults with hypertension. AIMS: To elucidate these groups by examining the characteristics of patients attending an Irish hypertension service, thus informing future management of hypertension. METHODS: Patients were recruited at consecutive hypertension clinics at St James Hospital, Dublin from July to September 2019. Following patient consent, patient data were recorded to identify patient characteristics as well as the results of investigations, blood pressure (BP) measurements and the anti-hypertensive treatment of the study participants which were then analysed. RESULTS: Two hundred thirty-six patients were included in the study. Compared to those without RH, the RH group were more likely to be obese (OR 2.59 [95% CI 1.06 to 6.33]), to have cardiovascular disease (OR 3.07 [95% CI 1.56 to 6.02]) and to have a non-dipping BP pattern (OR 3.86 [95% CI 1.57 to 9.47]). Young adults comprised 27% of the cohort. Forty-seven percent of these patients were obese, 15.9% had hypertension in pregnancy and 22.2% had chronic headaches. Despite being prescribed less anti-hypertensives (1.41 vs 2.28; p < 0.05), the majority of young patients had a BP less than 140/90 mmHg, comparing favourably with older patients (OR 2.25 [95% CI 1.20 to 4.27]). CONCLUSION: This contemporary study highlights the high prevalence of obesity among RH patients and young adults with hypertension. Findings suggest that programs to combat hypertension must include interventions to address obesity.

Collaboration, supervision and patient safety in the era of COVID-19: an analysis of medical wards and ICU.

AIMS: COVID-19 resulted in significant changes across medical wards and ICU in St James's Hospital Dublin. This included the implementation of ward-based medical teams (WBMT). The purpose of this study was to identify how these structural changes affected inter-professional collaboration, supervision and patient safety. METHODS: Questionnaires were distributed to doctors working on medical wards and ICU at the height of the first wave of COVID-19. The sense of collaboration, patient safety and supervision were assessed. RESULTS: Fifty-three doctors took part in the study. Thirty-three (62%) felt that collaboration was better than normal. Forty-six (87%) of participants described supervision as "good" or "excellent". Thirty-one out of 40 participants (77%) felt that patient safety was better than normal. DISCUSSION: Implementation of WBMT may result in improved sense of collaboration, supervision and patient safety during COVID-19; however, the increased sense of solidarity and comradery felt during the initial surge make drawing these conclusions challenging.

The association between increasing oral anticoagulant prescribing and atrial fibrillation related stroke in Ireland.

AIMS: Recent increases in the number of patients with atrial fibrillation (AF) prescribed oral anticoagulants (OAC) are evident in Ireland and internationally, largely due to the availability of direct oral anticoagulants (DOACs). This study aimed to determine the rate of stroke in the context of increasing anticoagulation utilisation, with a focus on AF-related ischaemic stroke (IS). METHODS: Dispensing data for OACs were identified for the period 2010-2018 as well as hospital discharges for IS (2005-2018). Irish National Stroke Register data were used to elucidate the characteristics of patients with acute ischaemic stroke. RESULTS: The number of patients prescribed OACs increased by 94% from 2010-2018 with a significant change from 2013 (ß = 2.57, P = .038), associated with a large increase in the number of patients on DOACs. There was 3.3-fold increase in expenditure on OACs nationally from 2013 to 2018, of which 94% was DOAC related. Using the 2013 timepoint, ischaemic stroke rates until 2018 did not show a significant deviation from the previous trend (ß = 0.00, P = .898). The percentage of AF-related ischaemic stroke was stable from 2013 to 2017 with a 4.5% decrease in 2018. The percentage of ischaemic stroke patients with previously diagnosed AF decreased from 2013 to 2018; however, there was an increase in the percentage of ischaemic strokes while on OAC in this cohort. CONCLUSION: Large increases in OAC utilisation have not resulted in changes in ischaemic stroke rates at a national level. The percentage of ischaemic strokes with a previous diagnosis of AF has decreased indicating a possible benefit from greater OAC utilisation. However, the percentage presenting with an ischaemic stroke while on OAC treatment is increasing. The increase in patients presenting with stroke while treated with OAC may largely reflect the national increase in patients prescribed DOACs but the findings raise concerns about treatment failures. The real-world effectiveness of DOACs requires further examination.
