Integrated renal-palliative care in Germany- Results from a survey on end of life care in a non-profit provider.

Palliative care-related problems in end-stage renal patients are similar to those of cancer patients. While the literature on renal palliative care is growing, real-world data on practice patterns of an integrated palliative care approach (IPCA) in Germany are lacking. An anonymous survey of end of life care (ELC; conservative treatment, dialysis withdrawal, decision making) was mailed to head physicians of adult renal centers (N = 198) including 13structured questions and 1 open question for more detailed information on the current state of ELC. Afree text analysis of the quality of established care and further requirements was provided. Responses were received from 122 centers (62%) with 14,197 dialysis and 159,652 renal outpatients. Of the 122 centers 86 provided detailed responses to the open question and 4 different thematic patterns could be identified: centers with successfully established ELC (N = 17, 20%, group1), those where intensified training and education were required (N = 19, 22%, group2), centers which required structural improvement to establish IPCA (N = 39, 45%, group3) and those which did not require further supportive measures (N = 11, 13%, group4). Physician's age, sex, years of working in renal medicine, center size, and proportion of dialysis withdrawal and conservative treatment were not significantly different between the groups. Despite equal general conditions, only 20% reported successfully established IPCA. Two out of three centers requested specific measures to establish or improve palliative care. Implementation of IPCA is hampered by educational and structural constraints. These real-world data suggest that structural determinants and soft skills (e.g. team motivation, leadership) can influence ICPA.

Epidemiology of healthcare-associated infection reported from a hospital-wide incidence study: considerations for infection prevention and control planning

The measure of disease frequency most widely used to report healthcare-associated infection (HAI) is the point-prevalence survey. Incidence studies are rarely performed due to time and cost constraints; they show which patients are affected by HAI, when and where, and inform planning and design of infection prevention and control (IPC) measures. To determine the epidemiology of HAI within a general and a teaching hospital in Scotland. A prospective observational incidence study was undertaken for one year from April 2018 using data collected as part of the Evaluation of Cost of Nosocomial Infection (ECONI) study. A novel, robust approach was undertaken, using record linkage to national administrative data to provide full admission and discharge information. Cases were recorded if they met international HAI definitions. Incidence of HAI for the combined hospitals was 250 HAI cases per 100,000 acute occupied bed-days (AOBD). Highest frequency was in urinary tract (51.2 per 100,000 AOBD), bloodstream (44.7), and lower respiratory tract infection (42.2). The most frequently reported organisms were Escherichia coli, Staphylococcus aureus, and norovirus. Incidence of HAI was higher in older people and emergency cases. There was an increase in the rate of HAI in summer months (pneumonia, respiratory, surgical, and gastrointestinal infection) and in winter months norovirus gastrointestinal infection (P < 0.0001). The highest incidence specialties were intensive care, renal medicine, and cardiothoracic surgery. HAI occurred at a median of 9 days (interquartile range: 4-19) after admission. Incidence data were extrapolated to provide an annual national estimate of HAI in NHS Scotland of 7437 (95% confidence interval: 7021-7849) cases. This study provides a unique overview of incidence of HAI and identifies the burden of HAI at the national level for the first time. Understanding the incidence in different clinical settings, at different times, will allow targeting of IPC measures to those patients who would benefit the most.

Impact of changing medical workforce demographics in renal medicine over 7 years: Analysis of GMC national trainee survey data

Increasing numbers of doctors in training are taking career breaks, with burnout cited as a potential cause. This study analysed General Medical Council (GMC) national training survey data (renal medicine) to understand the impacts of changing workforce demographics on trainee outcomes and wellbeing. Increasing proportions of female, Black, Asian and minority ethnic (BAME), and international medical graduates are entering the workforce. Specialty exam pass rates have fallen and are lower for BAME and international medical graduates in renal medicine. Time to complete higher specialty training has increased for female trainees. Self-reported burnout rates for renal trainees were higher than other medical specialties and highest for male BAME trainees. Burnout was only partially mitigated by less-than-full-time working, but had no impact on progression, sick-leave or time out of training. It is important to recognise changes to the workforce and proactively plan to effectively support a more diverse group of trainees, to enable them to succeed and reduce differential attainment.

Urinary metabolic profile and stone composition in kidney stone formers with and without heart disease

ObjectiveKidney stone disease seems to be associated with an increased risk of incident cardiovascular outcomes; the aim of this study is to identify differences in 24-h urine excretory profiles and stone composition among stone formers with and without cardiovascular disease (CVD).MethodsData from patients attending the Department of Renal Medicine’s metabolic stone clinic from 1995 to 2012 were reviewed. The sample was divided according to the presence or absence of CVD (myocardial infarction, angina, coronary revascularization, or surgery for calcified heart valves). Univariable and multivariable regression models, adjusted for age, sex, BMI, hypertension, diabetes, eGFR, plasma bicarbonate and potential renal acid load of foods were used to investigate differences across groups.Results1826 patients had available data for 24-h urine analysis. Among these, 108 (5.9%) had a history of CVD. Those with CVD were older, have higher prevalence of hypertension and diabetes and lower eGFR. Univariable analysis showed that patients with CVD had significantly lower 24-h urinary excretions for citrate (2.4 vs 2.6 mmol/24 h, p = 0.04), magnesium (3.9 vs 4.2 mmol/24 h, p = 0.03) and urinary pH (6.1 vs 6.2, p = 0.02). After adjustment for confounders, differences in urinary citrate and magnesium excretions remained significant. No differences in the probability of stone formation or stone compositions were found.ConclusionsStoneformers with CVD have lower renal alkali excretion, possibly suggesting higheracid retention in stone formers with cardiovascular comorbidities. Randomizedclinical trials including medications and a controlled diet design are neededto confirm the results presented here.Graphic abstract

MO1041AWARENESS, KNOWLEDGE AND PERCEPTION OF CHRONIC KIDNEY DISEASE PATIENTS AT RENAL MEDICINE OUTPATIENTS' CLINIC, SINGLE CENTRE EXPERIENCE

Abstract Background and Aims Chronic kidney disease (CKD) is a major cause of morbidity and mortality in the Sultanate. Many preventive measures have focused on early detection and education. Hence, awareness and education of kidney disease influence positively its medical management and diminish significantly the economic burden on public health. Knowledge of CKD and risk factors increases the perception of being at high risk and increasing health seeking behaviour. We conducted a longitudinal survey at Renal Medicine Department among our patients to assess the level of awareness, knowledge of CKD and the treatment options. Method We used a pretested structured questionnaire to collect information on socio-demographic and knowledge of patients attending Renal Medicine Department. The questionnaire was distributed to all CKD patients of at least one-year duration after their diagnosis. Results A total of 200 patients completed this study, mainly from the capital region. The mean age was 50 (SD 17.1) years for male participants and 42.3 (SD 16) years for female participants. The majority (74.3%) knew the reason for their referral to nephrologist. 31% of the patients with CKD reported their shock when informed about their kidney status by the nephrologist at the first time. Two third (64%) of patients reported having no knowledge of their kidney function and 50% of them were not aware about renal replacement therapy options. 52.1% of participants refused for early access creation. 22% of them expressed their refusal for the early access creation as they have no uremic signs. Finally, 60% of the study participants had no family member attending with them during their clinic visit. Conclusion Patients and their family should receive enough information and education regarding the nature of renal disease and the options for the treatment to allow them to make an informed decision about the management of their CKD. Awareness of the factors associated with a well-informed-decision making in the treatment of CKD can provide health professionals with evidence on how best to deliver education programs for patients and their families. It may also enhance communication and improve the capacity for patient and family involvement in shared decision making.

MO009ROLE OF GDF-15, YKL-40, AND MMP-9 IN PATIENTS WITH ESKD: FOCUS ON SEX SPECIFIC ASSOCIATIONS WITH VASCULAR OUTCOMES AND ALL-CAUSE MORTALITY

Abstract Background and Aims This study was performed on behalf of the GOING-FWD Consortium. The importance of sex difference in the development of cardiovascular complications is well appreciated, however, further studies are warranted to assess if sex specific pathophysiological changes occur under uremic environment. Little is known about the relationship between the uremic phenotype and novel cardiovascular biomarkers like growth differentiation factor 15 (GDF-15), cartilage glycoprotein 39 (YKL-40), and matrix metalloproteinase 9 (MMP9), and if they have a sex specific effects in relation to inflammation, vascular remodelling, cardiovascular outcomes and all-cause mortality. Therefore, we hypothesise that there is a sex specific relationship between GDF-15, YKL-40, MMP9 and vascular outcomes defined as athero-/arteriosclerosis and vascular calcification. Method ESKD patients (n = 231), males (n = 152) and females (n = 79), not receiving renal replacement therapy were selected from two ongoing prospective CKD cohorts from the Division of Renal Medicine, Karolinska University Hospital, Sweden. Three putative CVD biomarkers, GDF-15, YKL-40 and MMP9 were analysed using enzyme-linked immunosorbent assay (ELISA) kits. Biomarker level/activity was analysed in the context of gut microbiota derived TMAO, vascular calcification (determined as CAC score on CT scans, aortic valve calcification (AVC) and medial calcification on epigastric artery biopsies), inflammatory response, oxidative stress and all-cause mortality. Results The levels of investigated biomarkers have not differed between female and male patients with ESKD. However, GDF-15 correlated with TMAO in females from more severe cohort that are not receiving renal replacement therapy yet, whereas in males increased GDF-15 level was associated with higher Agatston score on CT-scans, inflammatory biomarker (IL-6) and oxidative stress biomarker 8-OHdG. None of biomarkers was related to intimal medial calcification assessed in epigastric artery biopsies. Comorbidity analysis revealed elevated GDF-15 levels in both females and males, while increased MMP-9 levels were observed only in females with diabetes mellitus, but not with CVD. When assessing death of any cause in our cohorts, both deceased males and females had higher GDF-15 concentration (p = 0.01 and p &amp;lt; 0.001, respectively), meanwhile only YKL-40 level was increased in deceased males (p = 0.02). Conclusion In summary, here we report that in males GDF-15 and YKL-40 were related to vascular calcification, inflammageing and oxidative stress, while in females the relationship of GDF-15 with TMAO was observed. Higher MMP-9 level was seen in males without diabetes and in females with confirmed diabetes mellitus. YKL-40 increase in males and GDF-15 in both males and females were associated with all-cause mortality. Our findings suggest that sex specific associations exist and those could have a potential to affect development of cardiovascular complications in patients with ESKD.

Sedation Rate Reduction in Paediatric Renal Nuclear Medicine Examinations: Consequences of a Targeted Audit.

Background: Nuclear medicine investigations are essential diagnostic tools in paediatric urology. Child-orientated examination techniques and the avoidance of sedation or anaesthesia vary in different institutions. We aimed at evaluating child friendly measures in our department to identify the potential for improvement. Based on these data, we changed the standards regarding the sedation policy and consequently re-evaluated sedation rates. Methods: Four-hundred thirty-five consecutive investigations were evaluated regarding the need for sedation, outcome and patient satisfaction at our department. After the revision of our department standards, we re-evaluated 159 examinations. Statistical analysis was performed with JUMBO (Java-supported Münsterian biometrical platform). Results: Eighty-six percent (60/70) would agree to perform an investigation under identical conditions again. Seventy-seven percent (17/22) of eligible patients >5 years of age felt good during the investigation. By changing our sedation policy, we could reduce the sedation rate from 27.1% to 7.5% (p < 0.0001; OR 0.219 95% CI 0.111–0.423). Conclusion: The evaluation of child friendly examination protocols demonstrated high reliability and patient satisfaction using situational sedation with a relatively high proportion of patients being sedated. Through protocol adaption with clear age limits, individual indication and education of staff, as well as the use of optimized sedatives, the need for sedation could be further reduced whilst maintaining a high patient satisfaction.

Point-of-care testing technologies for the home in chronic kidney disease: a narrative review.

Point-of-care testing (POCT) performed by the patient at home, paired with eHealth technologies, offers a wealth of opportunities to develop individualized, empowering clinical pathways. The non-dialysis-dependent chronic kidney disease (CKD) patient who is at risk of or may already be suffering from a number of the associated complications of CKD represents an ideal patient group for the development of such initiatives. The current coronavirus disease 2019 pandemic and drive towards shielding vulnerable individuals have further highlighted the need for home testing pathways. In this narrative review we outline the evidence supporting remote patient management and the various technologies in use in the POCT setting. We then review the devices currently available for use in the home by patients in five key areas of renal medicine: anaemia, biochemical, blood pressure (BP), anticoagulation and diabetes monitoring. Currently there are few devices and little evidence to support the use of home POCT in CKD. While home testing in BP, anticoagulation and diabetes monitoring is relatively well developed, the fields of anaemia and biochemical POCT are still in their infancy. However, patients’ attitudes towards eHealth and home POCT are consistently positive and physicians also find this care highly acceptable. The regulatory and translational challenges involved in the development of new home-based care pathways are significant. Pragmatic and adaptable trials of a hybrid effectiveness–implementation design, as well as continued technological POCT device advancement, are required to deliver these innovative new pathways that our patients desire and deserve.

The current state of artificial intelligence in cardiac transplantation.

The field of heart transplantation is a complex practice that combines both science and art to optimize the quality and quantity of an organ transplant recipient's life span. In the current age of Transplant Medicine there are many limiting factors that prevent potentially usable organs to be transplanted in addition to the many unknown factors in assessing the risk of posttransplant complications in a proactive manner. This review focuses on the current state, and potential use, and implementation of artificial intelligence technologies in the field of heart transplantation. Furthermore, the utilization of predictive algorithms to assess donor quality, graft function, posttransplant complications and prediction of high-risk complications will be discussed. Artificial intelligence technologies in the pretransplant population is also explored. Artificial intelligence process use has been increasing over the past decade. Early adoption in radiology and laboratory medicine have shown promise for future applications. Implementation of nascent technologies within the field of transplant medicine remains in its infancy. Cardiac and renal medicine have been recent focuses of large-scale artificial intelligence projects because of the wealth of data, the main limiting factor for producing accurate models. Understanding the true role of artificial intelligence in medicine is key - and has been divided into three areas of focus: data quality, interpretation, and clinical application. These areas allow the clinician to translate problems facing patients into algorithms utilized by data scientists to create solutions, which may provide in-depth analysis and detection of relationships not immediately clear. Although some published data has led to commercial products for cardiac, diabetic, and dermatologic applications -- widespread adoption remains limited to specialized centers. Artificial intelligence applications with clinically relevant models in transplant medicine have the potential to optimize organ utilization, prediction of complications, and potential pretransplant management, which may mitigate the need for transplant. Further translational projects are under development at major centers, with proof of concepts demonstrating validity and safety in the clinical setting. Limiting factors of infrastructure, expertise, and data availability continue to be addressed. Ongoing efforts for commercialization and large-scale trials will provide a foundation for the development of artificial intelligence applications in transplant medicine.

The utility of a local multidisciplinary working group to oversee the establishment of rapidly evolving standards of care and to support trial recruitment during the COVID-19 pandemic

Coronavirus disease 2019 (COVID-19) was first identified in December 2019 in Wuhan, China. The first analyses of cases described high numbers of critically ill patients requiring intensive care admission with significant late inflammatory features. By the time the first cases of SARS-CoV-2 infection were diagnosed in the UK, a wide range of drugs were under consideration and it became clear that the input of clinicians covering all organ systems (in particular, infectious diseases, haematology, rheumatology, renal medicine and intensive care) and of expert specialist pharmacists was necessary at the local level. Thus, an expert multidisciplinary (MDT) group within our organisation was convened to offer a standardised approach and robust clinical governance for the treatment of COVID-19 patients admitted to our hospitals and rapidly develop standards of care as evidence evolved. This commentary explores the methods and mechanisms for creating an MDT COVID-19 treatment working group which are applicable to any hospital likely to admit and care for high numbers of COVID-19 patients and demonstrates how the structure and governance of the group allowed for rapid adoption of both dexamethasone and tocilizumab into standard of care as data became available.

Pediatric acute kidney injury: new advances in the last decade.

Pediatric acute kidney injury (AKI) is a frequently missed complication. AKI has a significant impact on both short- and long-term outcomes in children. Within the last decade, there have been major landmark developments in this field of critical care pediatric nephrology. The topic was searched by two independent researchers using Google Scholar and PubMed and related studies published in the last 10 years. The terms used for the search were ‘pediatric acute kidney injury,’ ‘pediatric acute renal failure,’ ‘pediatric dialysis,’ ‘biomarkers,’ ‘nephrotoxins,’ ‘nephrotoxicity in children,’ and ‘pediatric critical care nephrology.’ We found that AKI is common in critically ill neonates and children. Among the various definitions, the Kidney Disease: Improving Global Outcomes (KDIGO) definition is most commonly used. In addition, it is imperative to risk stratify sick children at admission in the hospital to predict AKI and worse outcomes as this aids in early management. There are now major landmark trials that describe the epidemiology, prevention, and management guidelines in this field and health care professionals need to be aware they should diagnose AKI early. Overall, this review highlights the landmark studies in the last decade and shows that early diagnosis and management of AKI in ‘at risk’ children can improve outcomes.

Clinical features of neurogenic bladder with vesicoureteral reflux in children

OBJECTIVE To study the clinical features of vesicoureteral reflux (VUR) in children with neurogenic bladder (NB), and to provide a reference for its early diagnosis and treatment. METHODS Clinical data were collected from 26 children with NB and urinary tract infection who were admitted to the Department of Pediatric Nephrology from January 2014 to December 2019. According to the presence or absence of VUR, the children were divided into a VUR group with 11 children and a non-VUR group with 15 children. Clinical features were compared between the two groups. RESULTS Compared with the non-VUR group, the VUR group had a significantly higher proportion of children with non-Escherichia coli urinary tract infection, hydronephrosis (the severity of hydronephrosis increased with the grade of VUR), abnormal 99mTc-DMSA renal scanning findings, elevated ratios of urinary albumin, urinary IgG and urinary transferrin to creatinine, increased residual urine volume, and increased detrusor leak point pressure (P < 0.05). CONCLUSIONS When NB children have the clinical manifestations of non-Escherichia coli urinary tract infection, hydronephrosis, abnormal 99mTc-DMSA renal scanning findings, glomerular proteinuria, increased bladder residual urine volume, and high detrusor leak point pressure, such children may already have VUR, and so diagnosis and intervention should be performed as early as possible.

The mixed reality medical ward round with the MS HoloLens 2: Innovation in reducing COVID-19 transmission and PPE usage

The COVID-19 pandemic necessitated changes to the traditional medical ward round to protect staff and patients. This study investigated the value and acceptability of using the Microsoft HoloLens 2 mixed reality headset in a COVID-19 renal medicine ward. The HoloLens 2 was used during the height of the COVID-19 pandemic and it was compared with the days prior to its introduction. Staff exposure to COVID-19 and PPE usage were measured, and staff and patients were surveyed on the HoloLens 2 experience. The average ward round was significantly shorter with the use of the HoloLens 2 (94 minutes vs 137 minutes; p=0.006). With the HoloLens 2, only the consultant was in direct contact with COVID-19 patients compared with up to seven staff members on a normal ward round. Personal protective equipment usage was reduced by over 50%. Both staff and patients were positive about its use but raised some important concerns. The HoloLens 2 mixed reality technology is an innovative solution to the challenges posed by COVID-19 to the traditional medical ward round.

Professor Hugh MacLean: one of the first British military research nephrologists and the pioneer of the first United Kingdom veterans' renal clinic.

Few people have been as successful in bringing together basic research, clinical science, and a contribution to military medicine as Professor Hugh MacLean. However, today he is almost forgotten. During World War 1, practicing within the realms of the new field of renal medicine, with minimal resources and in a military hospital, he conducted one of the first large-scale Medical Research Committee investigations into war nephritis involving 60,000 subjects. After the war he set up and practiced, amongst other specialties, in the field of veteran medicine and established the concept of the one-stop renal clinic. After achieving significant academic recognition, he was unfortunately affected by mental health problems, possibly related to his wartime experiences, which brought an illustrious career to an untimely end.

Insights into Futuristic Renal Medicine.

The revolutionary innovations in biology and information technology influenced many medical and health disciplines. Although it is lagging behind others, renal medicine entered this chain of events. Nephrology and renal transplantation have many inherent challenges that needed to be addressed innovatively to receive these new frontiers in medicine. In a connected high biotech future, the applications of regenerative medicine, nanotechnology, genomics, artificial intelligence, 3D organ bioprinting, and smartphone applications will reshape the practice and research of renal medicine. Certainly, this will have a positive impact on patients' outcomes and the health-care system. These changes are coming, but with new challenges such as excess costs, and many moral challenges. Providing precise equitable care with maintaining patient's privacy and values will be difficult. In this review, we provide insights into future approaches to renal care.
