Impact of daily cyclic enteral nutrition versus standard continuous enteral nutrition in critically ill patients: a study protocol for a randomised controlled trial in three intensive care units in France (DC-SCENIC).

INTRODUCTION: Current guidelines on clinical nutrition of ventilated patients in the intensive care unit (ICU) recommend initiating continuous enteral nutrition within 48 hours of ICU admission when feasible. However, discontinuous feeding regimens, alternating feeding and fasting intervals, may have an impact on clinical and patient centred outcomes. The ongoing "Impact of daily cyclic enteral nutrition versus standard continuous enteral nutrition in critically ill patients" (DC-SCENIC) trial aims to compare standard continuous enteral feeding with daily cyclic enteral feeding over 10 hours to evaluate if implementing a fasting-mimicking diet can decrease organ failure in ventilated patients during the acute phase of ICU management. METHODS AND ANALYSIS: DC-SCENIC is a randomised, controlled, multicentre, open-label trial comparing two parallel groups of patients 18 years of age or older receiving invasive mechanical ventilation and having an indication for enteral nutrition through a gastric tube. Enteral feeding is continuous in the control group and administered over 10 hours daily in the intervention group. Both groups receive isocaloric nutrition with 4 g of protein per 100 mL, and have the same 20 kcal/kg/day caloric target. The primary endpoint is the change in the Sequential Organ Failure Assessment score at 7 days compared with the day of inclusion in the study. Secondary outcomes include daily caloric and protein delivery, digestive, respiratory and metabolic tolerance as well as 28-day mortality, duration of mechanical ventilation and ventilator-free days. Outcomes will be analysed on an intention-to-treat basis. Recruitment started in June 2023 in 3 French ICU's and a sample size of 318 patients is expected by February 2026. ETHICS AND DISSEMINATION: This study received approval from the national ethics review board on 8 November 2022 (Comité de Protection des Personnes Sud-Est VI, registration number 2022-A00827-36). Patients are included after informed consent. Results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05627167.

Postoperative prophylactic intermittent noninvasive ventilation versus usual postoperative care for patients at high risk of pulmonary complications: a multicentre randomised trial.

BACKGROUND: Pulmonary complications are an important cause of morbidity and mortality after surgery. We evaluated the clinical effectiveness of noninvasive ventilation (NIV) in preventing postoperative acute respiratory failure. METHODS: This is an open, multicentre randomised trial that included patients at high risk of postoperative pulmonary complications after elective or semi-urgent surgery with an Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score ≥45. Patients were randomly assigned to intermittent prophylactic face-mask NIV for 6-8 h day-1 or usual postoperative care. The primary outcome was in-hospital acute respiratory failure within 7 days after surgery. Patients who underwent surgery and postoperative extubation were included in the modified intended-to-treat analysis. Results are presented as n (%) and odds ratios (ORs) with 95% confidence intervals. RESULTS: Between November 2017 and October 2019, 266 patients were randomised and 253 included in the main analysis. Of these, 203 (80.2%) were male with a mean age of 68 (11) yr and an ARISCAT score of 53 (6); 237 subjects (93.7%) underwent cardiac or thoracic surgery. There were 125 patients allocated to prophylactic NIV and 128 to usual care. Unplanned treatment termination occurred in 58 subjects in the NIV group, which was linked to NIV discomfort for 36 subjects. There was no difference in the incidence of the primary outcome of postoperative acute respiratory failure between treatment groups (NIV: 30 of 125 subjects [24.0%] vs usual care: 35 of 128 subjects [27.3%]; OR 0.97 [0.90-1.04]; P=0.54). CONCLUSIONS: Prophylactic NIV was difficult to implement after high-risk surgery because of low patient compliance. Prophylactic NIV did not prevent acute respiratory failure. CLINICAL TRIAL REGISTRATION: NCT03629431 and EudraCT 2017-001011-36.

Prognostic accuracy of using lactate in addition to the quick Sequential Organ Failure Assessment score and the National Early Warning Score for emergency department patients with suspected infection.

BACKGROUND: The aim of this study was to determine whether: (1) the quick Sequential (Sepsis-related) Organ Failure Assessment (qSOFA) and National Early Warning Score (NEWS) clinical prediction tools alone, (2) modified versions of these prediction tools that integrate lactate into their scores, or (3) use of the two tools in tandem with lactate better predicts in-hospital 28-day mortality among adult EDpatients with suspected infection. METHODS: From 1 January through 31 December 2018, this retrospective cohort study enrolled consecutive adult patients with suspected infection evaluated at two EDs in France. Patients were included if blood cultures were obtained and non-prophylactic antibiotics were administered in the ED. qSOFA, NEWS criteria and lactate measurements were recorded when patients were clinically suspected of having an infection. Two composite scores (lactate qSOFA (LqSOFA) and lactate NEWS (LNEWS)) integrating lactate were created. Diagnostic test performances for predicting in-hospital mortality within 28days were assessed for qSOFA≥2, LqSOFA≥2, qSOFA≥2 or lactate≥2 mmol/L, and for NEWS≥7, LNEWS≥7, and NEWS≥7 or lactate≥2 mmol/L. RESULTS: 1003 patients were included, 130 (13%) of whom had died by day 28. Sensitivities for 28-day mortality were 50% (95%CI41% to 59%) for qSOFA≥2,69% (95% CI60% to 77%) for LqSOFA≥2,77% (95% CI69% to 84%) for qSOFA or lactate≥2 mmol/L; and 69% (95% CI60% to 77%) for NEWS≥7, 80% (95% CI72% to 86%) for LNEWS≥7, 87% (95% CI80% to 92%) for NEWS≥7 or lactate≥2 mmol/L. CONCLUSION: Lactate used in tandem with qSOFA or NEWS yielded higher sensitivities in predicting in-hospital 28-day mortality, as compared with integration of lactate into these prediction tools or usage of the tools independently.

Palliative care for case managers: Building capacity to extend community-based palliative care to underserved older adults.

Palliative care has demonstrated effectiveness in alleviating the biological, emotional, social, and spiritual symptoms that accompany serious illness, and improving quality of life for seriously ill individuals and their family members. Despite increasing availability, there are significant disparities in access to and utilization of palliative care, particularly among diverse, low-income, and community-dwelling older adults with chronic illness. Training frontline service providers is a novel approach to expanding access to palliative care among underserved elders. This article presents a process and outcome evaluation of a palliative care curriculum that was developed and piloted for geriatric case managers in a large urban area. We describe the background, planning, design, implementation, and preliminary outcomes associated with a pilot implementation of the curriculum. We conclude with implications for replicating efforts to enhance frontline providers' knowledge, skills, and self-efficacy in extending palliative care to communities that lack access to critical supports for their burdensome symptoms.

Effects of the COVID-19 Outbreak on Elder Mistreatment and Response in New York City: Initial Lessons.

New York City is currently experiencing an outbreak of COVID-19, a highly contagious and potentially deadly virus, which is particularly dangerous for older adults. This pandemic has led to public health policies including social distancing and stay-at-home orders. We explore here the impact of this unique crisis on victims of elder mistreatment and people at risk of victimization. The COVID-19 outbreak has also had a profound impact on the organizations from many sectors that typically respond to protect and serve victims of elder mistreatment. We examine this impact and describe creative solutions developed by these organizations and initial lessons learned in New York City to help inform other communities facing this pandemic and provide guidance for future crises.

Assessing the palliative care needs and service use of diverse older adults in an urban medically-underserved community.

Although palliative care (PC) has become increasingly familiar, considerable gaps persist in access to and use of services. Community-based programs remain rare, and low-income, minority communities significantly under-utilize hospice and palliative services. We used community-based participatory research (CBPR) methods to conduct a mixed-methods community needs assessment of seriously-ill older adults (n=100) and providers from community-based programs and churches (n=41) in an urban medically-underserved community in the U.S. to explore: (I) the prevalence and severity of illness-related symptoms and psychosocial-spiritual concerns; (II) the scope and quality of community supports helping older adults manage their symptoms; and (III) the perceptions and utilization of palliative and supportive care services among older adults and community-based service providers. Participants reported high rates of chronic illness-related symptoms (i.e., pain, fatigue, sleeping difficulties, depression, and anxiety), and many described unmet needs around symptom management. Few had ever utilized PC or pain management services, and most relied primarily on family, friends, and faith communities to help them manage burdensome symptoms. Barriers included lack of familiarity with PC, limited access and financial concerns. Older adults were largely unfamiliar with PC, and many described unmet needs and desire for help with symptom burden. Findings support the need to further explore community-level and cultural barriers to PC among diverse, underserved older adults. Development of innovative community partnerships may help raise awareness of PC and address the physical and psychosocial-spiritual challenges facing chronically-ill minority older adults and their families.

Safety and efficiency of a redirection procedure toward an out of hours general practice before admission to an emergency department, an observational study.

BACKGROUND: Primary care patients are often cited as a cause of Emergency Department overcrowding (ED). The aim of this study was to evaluate a physician led redirection procedure of selected patients towards an out of hours general practice (OHGP) in an Emergency Department with 55,000 admissions per year. METHODS: Observational monocentric study over a period of 2 months. Every patient redirected to the OHGP was included and subsequently contacted by telephone to answer a standardized questionnaire, in order to measure: Redirection rate over the entire period and during weekdays or weekends/holiday Rate of redirected patients who went to the OHGP Rate of redirected patients who consulted in an ED in the next 72 h for the same reason Redirected patients' satisfaction rate RESULTS: During the study period 9551 patients presented to the ED, of which 288 were redirected towards the OHGP (3%). The redirection rate was 1.9% during weekdays and 5.7% during weekends/holiday (p < 0.001). Of the redirected patients, 77% answered the telephone interview. Ninety percent of these patients consulted the OHGP. The main reasons for not consulting were: unduly long wait, opening hours not suitable, too costly. The rate of redirected patients who consulted in an ED in the following 72 h for the same reason was 4.1%. The satisfaction rate was 79.6% among interviewed patients. CONCLUSIONS: A physician led procedure to redirect selected patients from the ED towards an OHGP results in a low redirection rate, unlikely to have a significant effect on ED patient flow. However, the procedure is safe and well accepted by a majority of patients.

Community-based participatory research: understanding a promising approach to addressing knowledge gaps in palliative care.

Concern over the need for effective and accessible healthcare for individuals with advanced chronic illness has drawn attention to the significant gaps in our knowledge of palliative medicine. To advance our understanding of this field, community-based participatory research (CBPR) is proposed as a tool for future research initiatives. This paper offers a rationale for how CBPR may be employed to address specific gaps in palliative care research. Several examples where this approach has been used previously are described, and potential obstacles to implementing this research method are delineated. Despite challenges to incorporating CBPR to palliative care research, this approach holds substantial potential to advance our current understanding of the field and promote sensitivity for future programs, practices and policies.

Routine biological tests in self-poisoning patients: results from an observational prospective multicenter study.

CONTEXT: Routine biological tests are frequently ordered in self-poisoning patients, but their clinical relevance is poorly studied. MATERIALS AND METHODS: This is a prospective multicentric observational study conducted in the emergency departments and intensive care units of 5 university and nonuniversity French hospitals. Adult self-poisoning patients without severely altered vital status on admission were prospectively included. RESULTS: Routine biological test (serum electrolytes and creatinine, liver enzymes, bilirubin, blood cell count, prothrombin time) ordering and results were analyzed. A total of 1027 patients were enrolled (age, 40.2 ± 14 years; women, 61.5%); no patient died during the hospital stay. Benzodiazepine was suspected in more than 70% of cases; 65% (range, 48%-80%) of patients had at least 1 routine biological test performed. At least 1 abnormal test was registered in 23% of these patients. Three factors were associated with abnormal test results: age older than 40 years, male sex, and poisoning with a drug known to alter routine tests (ie, acetaminophen, NSAIDs, metformine, lithium). Depending on these factors, abnormal results ranged from 14% to 48%. Unexpected severe life-threatening conditions were recorded in 6 patients. Only 3 patients were referred to the intensive care unit solely because of abnormal test results. CONCLUSION: Routine biological tests are commonly prescribed in nonsevere self-poisoning patients. Abnormal results are frequent but their relevance at bedside remains limited.
