Specificity of severe AKI aetiology and care in the elderly. The IRACIBLE prospective cohort study.

INTRODUCTION: Acute Kidney Injury (AKI) is increasingly common in people over 65 years of age, but its causes and management are poorly described. The purpose of this study was to describe the causes, management and prognosis of patients over 65 hospitalised for severe acute kidney injury (AKI) in all departments of a tertiary centre. METHOD: The prospective IRACIBLE (IRA: AKI in French; CIBLE: target in French) cohort included 480 patients hospitalised at a university hospital over 18 months for severe AKI or subgroup of AKIN3 (Acute Kidney Injury Network classification) defined by an acute creatinine increase > 354 µmol/L or managed with acute renal replacement therapy (RRT). The history, aetiology of AKI, management, and prognosis were compared in three age groups: < 65, 65-75, and > 75 years. RESULTS: The study population included 480 subjects (73% men) with a median body mass index (BMI) of 26.6 kg/m2 [23.3, 30.9], 176 (37%) diabetic patients, 124 (26%) patients < 65 years, 150 (31%) 65-75 years and 206 (43%) > 75 years. Increasing age class was associated with more comorbidities, a significantly lower median estimated glomerular filtration rate (eGFR) 6 months before inclusion (82; 62; 46 ml/min/1.73 m2, p < 0.05) and aetiology of AKI, which was more often obstructive (12%; 15%; 23%, p = 0.03) or part of a cardio-renal syndrome (6%; 9%; /15%, p = 0.04). Older patients were less often managed in the intensive care unit  (54%; 47%; 24%, p < 0.0001), were less frequently treated by RRT (52%; 43%; 31%, p < 0.001) and received fewer invasive treatments  (6%; 9%; 22%, p < 0.0001). Older survivors returned home less often (80%; 73%; 62%, p = 0.05) in favour of transfers to rehabilitation services (10%; 13%; 22%) with higher mortality at 3 months (35%; 32%; 50%, p < 0.0001). CONCLUSION: Older patients hospitalised for severe AKI have a specific profile with more comorbidities, lower baseline renal function, an aetiology of AKI of mainly extra-parenchymal causes and a complex pathway of care with an overall poor prognosis.

Low performance of prognostic tools for predicting death before dialysis in older patients with advanced CKD.

INTRODUCTION: Chronic kidney disease (CKD) is a disease which is spreading worldwide, especially among older patients. Several prognostic scores have been developed to predict death in older CKD patients, but they have not been validated. We aimed to evaluate the existing risk scores for predicting death before dialysis start, identified via an in-depth review, in a cohort of elderly patients with advanced CKD. METHODS: We performed a review to identify scores predicting death, developed in and applicable to CKD patients. Each score was evaluated with an absolute risk calculation from the patients' baseline characteristics. We used a French prospective multicentre cohort of elderly patients (> 75 years) with advanced CKD [estimated glomerular filtration rate (eGFR) < 20 mL/min/1.73 m2], recruited from nephrological centres, with a 5-year follow-up. The outcome considered was death before initiating dialysis. Discrimination [area under curve (AUC)], calibration and Brier score were calculated for each score at its time frame. RESULTS: Our review found 6 equations predicting death before dialysis in CKD patients. Four of these (GOLDFARB, BANSAL, GRAMS 2 and 4 years) were evaluated. The validation cohort (Parcours de Soins des Personnes Âgées Parcours de Soins des Personnes Âgées, PSPA) included 573 patients, with a median age of 82 years and a median eGFR of 13 mL/min/1.73 m2. At the end of follow-up, 287 (50%) patients had started dialysis and 238 (41%) patients had died before dialysis. The four equations evaluated showed average discrimination (AUC 0.61-0.70) and, concerning calibration, a global overestimation of the risk of death. DISCUSSION: The available scores predicting death before dialysis showed low performance among older patients with advanced CKD in a French multicentre cohort, indicating the need to upgrade them or develop new scores for this population.

Spreading geriatric oncology culture through professional caregivers: Results of a French massive open online course (MOOC).

Geriatric oncology is based on the synergy between several professionals whose common goal is to improve care for older patients with cancer. This requires sharing a common core of knowledge to facilitate collaboration between them. To date, training in geriatric oncology has been limited in scope and difficult to access for caregivers, particularly nurses and healthcare aides. To meet this need, a massive open online course (MOOC), in geriatric oncology has been developed in France. This kind of course aims to provide simultaneous access for a large number of participants and to foster communication with the pedagogical team through discussion forums. The first session of the MOOC, which has been set up in the Occitania region of France, went online nationwide from March 6 to June 23, 2020. Despite the SARS CoV-2 global health crisis, 1020 people subscribed to the first session and 417 (40.9%) were certified at the end of the course. Most are nurses (35.2%) and work outside Occitania (56.3%). A survey revealed a high satisfaction level regarding relevance of lessons (97.9%), pedagogical quality of teaching team (97.9%), knowledge acquisition (93.6%), meeting learners' needs (90.4%) and practical value of the course (88.3%). This preliminary experience demonstrates the ability of this MOOC to spread the culture of geriatric oncology and the educational potential of this new type of online training.

[Development and assessment of a MOOC about delirium in geriatric oncology]. / Création et évaluation d'un MOOC sur le syndrome confusionnel en oncogériatrie.

INTRODUCTION: Among the themes to be addressed by a Massive Open Online Course (MOOC) on geriatric oncology, one of the priorities was delirium, due to its frequency, complications and difficulties encountered by healthcare professionals in diagnosing and managing delirium. Our study aims to evaluate professional practices in the area of education, regarding the evaluation of the content of a MOOC module about delirium syndrome in geriatric oncology. METHODS: We created a multidisciplinary group to define the scientific content, the pedagogical objectives, the scriptwriting and the development of a training module. The quality of instructional design was then evaluated according to eleven MOOC design principles to promote learning. Participants were studied. RESULTS: Seven of the eleven criteria for evaluating pedagogical quality were documented. Among the 1020 participants, 455 (44.6%) completed the final test concerning delirium: 417 (40.8%) passed the final test; 406 documented their profession and the region of France where they worked: 146 (32%) nurses (confirming the participation of the targeted audience), 103 (22.6%) doctors/pharmacists (illustrating the multi-professional interest of the thematic), with a wide distribution of the participants over the national territory. DISCUSSION: The multidisciplinary team's investment in developing these teaching materials strengthened the group's cohesion and valuated its professional skills. All teaching resources developed for access via the internet must be accompanied by an evaluation of the quality of the scientific content, objectives and teaching methods, before being able to appreciate its use in the field and assess its real impact on the participants' learning and practice.

Prevalence and prognostic impact of cachexia among older patients with cancer: a nationwide cross-sectional survey (NutriAgeCancer).

BACKGROUND: Nutritional impairment is common in cancer patients and is associated with poor outcomes. Only few studies focused on cachexia. We assessed the prevalence of cachexia in older cancer patients, identified associated risk factors, and evaluated its impact on 6 month overall mortality. METHODS: A French nationwide cross-sectional survey (performed in 55 geriatric oncology clinics) of older cancer patients aged ≥70 referred for geriatric assessment prior to treatment choice and initiation. Demographic, clinical, and nutritional data were collected. The first outcome was cachexia, defined as loss of more than 5% of bodyweight over the previous 6 months, or a body mass index below 20 kg/m2 with weight loss of more than 2%, or sarcopenia (an impaired Strength, Assistance with walking, Rise from chair, Climb stairs and Falls score) with weight loss of more than 2%. The second outcome was 6 month overall mortality. RESULTS: Of the 1030 patients included in the analysis [median age (interquartile range): 83 (79-87); males: 48%; metastatic cancer: 42%; main cancer sites: digestive tract (29%) and breast (16%)], 534 [52% (95% confidence interval: 49-55%)] had cachexia. In the multivariate analysis, patients with breast (P < 0.001), gynaecologic (P < 0.001), urinary (P < 0.001), skin (P < 0.001), and haematological cancers (P = 0.006) were less likely to have cachexia than patients with colorectal cancer. Patients with upper gastrointestinal tract cancers (including liver and pancreatic cancers; P = 0.052), with previous surgery for cancer (P = 0.001), with metastases (P = 0.047), poor performance status (≥2; P < 0.001), low food intake (P < 0.001), unfeasible timed up-and-go test (P = 0.002), cognitive disorders (P = 0.03) or risk of depression (P = 0.005), were more likely to have cachexia. At 6 months, 194 (20.5%) deaths were observed. Cachexia was associated with 6 month mortality risk (adjusted hazard ratio = 1.49; 95% confidence interval: 1.05-2.11) independently of age, in/outpatient status, cancer site, metastatic status, cancer treatment, dependency, cognition, and number of daily medications. CONCLUSIONS: More than half of older patients with cancer managed in geriatric oncology clinics had cachexia. The factors associated with cachexia were upper gastrointestinal tract cancer, metastases, poor performance status, poor mobility, previous surgery for cancer, cognitive disorders, a risk of depression, and low food intake. Cachexia was independently associated with 6 month mortality.

French general practitioners' attitude towards breast cancer in older women: A qualitative study.

INTRODUCTION: In France, general practitioners (GPs) are usually the first-line healthcare contact for breast cancer (BC) screening/diagnosis in older women, information about therapies, access to cancer specialists, management of comorbidities and follow-up. GPs' practices may influence the factors involved in the unfavorable prognosis of BC in older patients: delay in diagnosis, insufficiently active treatment and the impact of associated morbidities. OBJECTIVE: The aim of this study was to explore GPs' experience, to understand the factors which shape their care of older women with BC and to identify ways in which this care might be improved. METHOD: This was a two-part qualitative study among GPs following COREQ guidelines. We analysed themes arising from group and semi-directive personal interviews. RESULTS: GPs had diverse attitudes caused by 1/ the GPs' professional values, in response to their mission for local referral, their overall knowledge of the patient's context and wishes; 2/ the impact of comorbidities; 3/ the GPs' own experiences (confrontation with the disease, emotional ties established with the patient, embarrassment about examinations); 4/ prejudicial connotations (therapies judged as being too aggressive). GPs expressed interest for training, for inclusion in a coordinated multidisciplinary organisation with oncologists and geriatricians, confirming the GP's position (to better inform their patients, participate in the therapeutic decision and ensure the continuity of care). CONCLUSION: To improve their care of older patients with BC, GPs would welcome improved relationships with geriatricians and oncologists, more information support and a more clearly defined role in the geriatric oncology care pathway.

Quality of life determinants in older patients with cancer: Results from a French prospective monocenter cohort.

OBJECTIVES: The aim of this study is to describe determinants of quality of life (QOL) quoted by vulnerable older patients with cancer and compare them with domains included in cancer-specific QOL questionnaires. MATERIAL AND METHODS: This prospective, monocenter, observational study was performed in a French university hospital. Cancer patients Patients with cancer aged over 74 years were recruited when referred for an out-patient geriatric evaluation (n = 102). After geriatric assessment, they were invited to respond to open-ended questions, Q1: "For you, what is most important to have a good QOL?" Q2: "What could improve your QOL?" Q3: "What could worsen your QOL?" A Delphi process was conducted to categorize patient responses according to content analysis. RESULTS: The most frequently patient-reported determinants for high quality of life were maintaining close ties with family/friends or social relations, autonomy for decision and mobility without depending on others, being in good health, not suffering from pain and the absence of problems concerning relatives. Global health status, physical functioning/mobility, social functioning and worries about others were the more frequently mentioned QOL domains related to the EORTC QLQ-C30 and ELD14 questionnaires. Some determinants of QOL were not linked to pre-defined domains, some others without a 100% consensus after the Delphi process, illustrating the subjectivity of QOL analysis by a single practitioner. CONCLUSION: Patient interview with open-ended questions provides valuable supplementary information to QOL questionnaires, in order to personalize health related (cancer treatment, pain management…) and global (maintenance of autonomy and family/social relations…) assessment and intervention.

Impact of a pharmacist and geriatrician medication review on drug-related problems in older outpatients with cancer.

OBJECTIVES: Older patients with cancer have increased risk for comorbidity, polypharmacy (PP) and drug related problems (DRP). The aim of this study was to assess the effect of a clinical pharmacist and geriatrician medication review (MR) among older outpatients with cancer to optimize management of comorbidities during comprehensive geriatric assessment (CGA). MATERIAL AND METHODS: We conducted a single-center prospective study among older outpatients with cancer (≥75 years). A pharmacist consultation was added into CGA process. The clinical pharmacist detected and assessed PP and DRP such as potentially inappropriate medications (PIM) according to the Laroche French list and STOPP criteria, START criteria and adverse drug events (ADE) risk. After a multidisciplinary MR, the proposals for prescription modification were sent to general practitioners (GPs). RESULTS: Fifty-one consenting patients were recruited between May 2016 and March 2017, with a median age of 83 years. Prevalence of PP was 80.4%. 165 DRP were detected among 86% patients (median number of DRP = 3.0): 19.4% were misuse, 43.6% underuse, and 37.0% overuse. A significant decrease was observed in prevalence of PIM use (Laroche: 31.4% versus 5.9%, p = 0.002), START criteria (66.7% to 5.9%; P < 0.001) and ADE score (4.0 before MR versus 2.0 after, p = 0.023). A trend was observed for a lower number of medications (10.0 versus 8.0, p = 0.092) and on STOPP criteria prevalence (56.9% versus 31.4%, p = 0.12). CONCLUSION: A clinical pharmacist and a geriatrician MR is effective to detect and reduce DRP in older outpatients with cancer.

[Nutritional status of residents of a nursing home and optimisation of the working time of caregivers]. / État nutritionnel des résidents en Ehpad et optimisation du temps de travail des soignants.

The lack of time to devote to care is a frequent complaint of nurses and nursing assistants. The results of a study show that an improvement in the nutritional status of nursing home residents could help to improve their quality of life and to optimise the working time of the nursing teams, thanks to the reduction of pressure ulcers, diarrhoea, falls, fractures and infections.

Evaluation of prescription along three health-care periods in the elderly.

Polypharmacy, potentially inappropriate prescriptions and inadequate coordination between prescribers are among main factors explaining the occurrence of adverse drug events in elderly patients. Prospective and descriptive study of medication prescriptions for elderly patients during a continuous period of health-care: entry in an acute geriatric unit (T1), at discharge (T2) and two months after hospitalization (T3). A global iatrogenic risk was defined: presence of poly-pharmacy and/or PPI (Laroche criteria) and/or absence of quality indicators for prescription according to the French health authority. For the 79 patients (mean age 87), mean number of medication decreased from 7.33 (T1) to 6 (T2) (p=0.0018) and 6 (T3). Number of quality indicators for prescription improved from 6.67 (T1) to 6.92 (T2) (p=0.001) then decreased to 6.84 (T3). Number of PPI decreased from 1.16 to 0.42 between T1 and T2 (p=0.001) then increased to 0.59 at T3. The global iatrogenic risk indicator fluctuated from 80% (T1) to 64% (T2) and 75% (T3). Selected interventions were developed to prevent adverse drug events during hospitalization and ambulatory follow-up. If geriatric intervention can enhance quality of prescription, iatrogenic risk remains frequent all along health-care follow-up. A local study of prescriptions can be a first step to develop an adequate program for adverse drug events prevention.

[Professional's expectations to improve quality of care and social services utilization in geriatric oncology]. / Attentes des professionnels hospitaliers impliqués dans la prise en charge globale en oncogériatrie.

BACKGROUND: Coordination of a multidisciplinary and multi-professional intervention is a key issue in the management of elderly cancer patients to improve health status and quality of life. Optimizing the links between professionals is needed to improve care planning, health and social services utilization. METHODS: Descriptive study in a French University Hospital. A 6-item structured questionnaire was addressed to professionals involved in global and supportive cares of elderly cancer patients (name, location, effective health care and services offered, needs to improve the quality of their intervention). After the analysis of answers, definition of propositions to improve cares and services utilization. RESULTS: The 37 respondents identified a total of 166 needs to improve quality of care in geriatric oncology. Major expectations were concerning improvement of global/supportive cares and health care services utilization, a better coordination between geriatric teams and oncologists. Ten propositions, including a model of in-hospital health care planning, were defined to answer to professional's needs with the aim of optimizing cancer treatment and global cares. CONCLUSION: Identification of effective services and needs can represent a first step in a continuous program to improve quality of cares, according to the French national cancer plan 2014-2019. It allows federating professionals for a coordination effort, a better organization of the clinical activity in geriatric oncology, to optimize clinical practice and global cares.

[The elderly population on haemodialysis: evaluation, prevention and treatment of cognitive decline]. / La population âgée hémodialysée: évaluer et prendre en charge le risque de déclin cognitif.

Epidemiological data suggest a large prevalence of cognitive impairment in elderly patients on haemodialysis. They are frequently exposed to pathologies that affect the brain, and hold a plurality of risk factors for neurodegenerative and vascular dementia. Cognitive dysfunctions, because of their medical and socio-economical consequences, may led to discuss the indication for haemodialysis and its profit for the elderly patient. These facts highlight the advantage of a regular assessment of cognitive functions in this population. They also suggest the need in the future of a multidisciplinary intervention for these patients, for a better evaluation of interventions aimed on primary and secondary prevention of cognitive decline in the elderly group.
