Large-scale, mobile and technology-enhanced serious game for interprofessional education: pilot study and lessons learnt. J Interprof Care 2024:1-5. [PMID: 38656890 DOI: 10.1080/13561820.2024.2339291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 03/30/2024] [Indexed: 04/26/2024]
Abstract
Recent research suggests that serious gaming is a promising strategy for interprofessional education (IPE). This report describes the design and pilot testing of a large-scale, mobile, technology-enhanced serious game embedded in the IPE curriculum in Geneva, Switzerland. Organized into teams of eight, the students were tasked with finding a young patient who had just escaped from the intensive care unit. Through a series of 10 stations, they explored hospital- and community-based locations of the healthcare system and were engaged in various learning and game activities; they were rewarded with cues to unveil the mystery. A total of 582 undergraduate students from seven disciplines (medicine, midwifery, nursing, nutrition-dietetics, pharmacy, physiotherapy, and technology in medical radiology) took part. Survey results (response rate: 62.8%) suggest that an overall majority of students valued the game, particularly the collaborative experience of actively learning from others in autonomous teams. Qualitative feedback allowed us to identify future areas for improvement: simplifying the adventure storyline and optimizing student flow. Educational institutions across the world facing challenges when creating IPE activities will find in this report ideas and lessons learnt to use mobile technology and serious gaming for large cohorts of students.

Multivariate analysis of milk metabolite measures shows potential for deriving new resilience phenotypes. J Dairy Sci 2023; 106:8072-8086. [PMID: 37268569 DOI: 10.3168/jds.2023-23332] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 04/25/2023] [Indexed: 06/04/2023]
Abstract
In a context of growing interest in breeding more resilient animals, a noninvasive indicator of resilience would be very valuable. We hypothesized that the time-course of concentrations of several milk metabolites through a short-term underfeeding challenge could reflect the variation of resilience mechanisms to such a challenge. We submitted 138 one-year-old primiparous goats, selected for extreme functional longevity (i.e., productive longevity corrected for milk yield [60 low longevity line goats and 78 high longevity line goats]), to a 2-d underfeeding challenge during early lactation. We measured the concentration of 13 milk metabolites and the activity of 1 enzyme during prechallenge, challenge, and recovery periods. Functional principal component analysis summarized the trends of milk metabolite concentration over time efficiently without preliminary assumptions concerning the shapes of the curves. We first ran a supervised prediction of the longevity line of the goats based on the milk metabolite curves. The partial least square analysis could not predict the longevity line accurately. We thus decided to explore the large overall variability of milk metabolite curves with an unsupervised clustering. The large year × facility effect on the metabolite concentrations was precorrected for. This resulted in 3 clusters of goats defined by different metabolic responses to underfeeding. The cluster that showed higher β-hydroxybutyrate, cholesterol, and triacylglycerols increase during the underfeeding challenge was associated with poorer survival compared with the other 2 clusters. These results suggest that multivariate analysis of noninvasive milk measures show potential for deriving new resilience phenotypes.

Abstract
How can we improve the discussion and documentation of goals of care with older people and their relatives? When promoting advance care planning one is expected to address a threefold challenge: an ethical challenge, a quality of care - patient safety challenge, and a public health challenge. The aim of this article is to describe how we integrated advance care planning at the Geneva University Hospitals with a focus on the department of geriatrics and rehabilitation. We explain how we improved the documentation in the electronic medical records. We detail how we trained healthcare professionals and disseminated the information to patients and to the general public. Finally, we point out the success factors and barriers in this process, as they might be encountered by healthcare institutions and networks implementing advance care planning elsewhere in Switzerland.

Analysis of reproduction success, growth and milk trajectories and response to nutritional challenge in two Alpine goat lines selected on divergent longevity. Animal 2023; 17:101004. [PMID: 37944363 DOI: 10.1016/j.animal.2023.101004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 09/20/2023] [Accepted: 09/28/2023] [Indexed: 11/12/2023] Open
Abstract
This study aims to investigate whether the variation in reproduction success, growth, and milk trajectories is associated with different adaptive strategies in the short term (response to an acute nutritional challenge), using two Alpine goat lines. A total of 382 Alpine goats (179 low longevity (low_LGV) and 203 high longevity (high_LGV)), selected for divergent functional longevity from a commercial population, were monitored for 4 years and recorded for BW, reproduction and milking performance. Every year, an average of fifty primiparous goats were exposed to a 2-d nutritional challenge in early lactation. A polynomial model was used to analyse the lifetime trajectory of lactation and BW. A piecewise model was used to analyse the individual milk yield and responses of milk components to the nutritional challenges. The statistical analysis revealed that the two lines had a similar performance for total milk yield in the first lactation, BW at birth and at first kidding, litter size and weight, kidding interval and interval from the first insemination to conception. BW trajectories revealed that low_LGV goats had a greater BW in pregnancy but then lost more weight in early lactation compared to high_LGV goats, which showed a greater BW after kidding. Milk trajectories showed that the high_LGV goats had a higher initial milk yield, an earlier but less marked lactation peak and more persistency in milk production in late lactation than low_LGV goats. Except for milk protein content, quite similar response and recovery profiles of milk yield and milk fat content were observed during the challenge for both lines. The response to the challenge was positively correlated to the initial level of milk production in early lactation but negatively correlated with milk production decline after the peak. This finding suggests that the low_LGV goats were more adapted to allocate resources to meet an expected physiological change such as gestation and lactation. However, high_LGV goats allocate more than low_LGV goats for structural mass and may better cope with an unexpected environmental change such as nutritional deficit.

Effect of an interprofessional simulation program on patient safety competencies of healthcare professionals in Switzerland: a before and after study. JOURNAL OF EDUCATIONAL EVALUATION FOR HEALTH PROFESSIONS 2023; 20:25. [PMID: 37635290 PMCID: PMC10519772 DOI: 10.3352/jeehp.2023.20.25] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 08/11/2023] [Indexed: 08/29/2023]
Abstract
PURPOSE This study aimed to identify the effects of a 12-week interprofessional simulation program, operated between February 2020 and January 2021, on the patient safety competencies of healthcare professionals in Switzerland. METHODS The simulation training was based on 2 scenarios of hospitalized patients with septic shock and respiratory failure, and trainees were expected to demonstrate patient safety competencies. A single-group before and after study was conducted after the intervention-simulation program, using a measurement tool (the Health Professional Education in Patient Safety Survey) to measure the perceived competencies of physicians, nurses, and nursing assistants. Out of 57 participants, 37 answered the questionnaire surveys 4 times: 48 hours before the training, followed by post-surveys at 24 hours, 6 weeks, and 12 weeks after the training. The linear mixed effect model was applied for the analysis. RESULTS Four components out of 6 perceived patient safety competencies improved at 6 weeks but returned to a similar level before training at 12 weeks. Competencies of "communicating effectively," "managing safety risks," "understanding human and environmental factors that influence patient safety," and "recognize and respond to remove immediate risks of harm" are statistically significant both overall and in the comparison between before the training and 6 weeks after the training. CONCLUSION Interprofessional simulation programs contributed to developing some areas of patient safety competencies of healthcare professionals, but only for a limited time. Interprofessional simulation programs should be repeated and combined with other forms of support, including case discussions and debriefings, to ensure lasting effects.

Abstract
The COVID-19 pandemics has deeply impacted academic teaching and forced a complete shift to distance learning formats during the first and second waves. Medical education, among other professional training programs, relies also on practical and clinical immersion, while some of these clinical activities had to be postponed. This article analyzes how one medical school was able to maintain its teaching while ensuring clinical training and taking into account the psychological impact imputed to the lockdown. It also highlights the learning opportunities and unprecedented life experiences contributing to the training of tomorrow's physicians.

Abstract
Background Advance care planning, including advance directives, is an important tool that allows patients to express their preferences for care if they are no longer able to express themselves. We developed Accordons-nous, a smartphone app that informs patients about advance care planning and advance directives, facilitates communication on these sensitive topics, and helps patients express their values and preferences for care. Objective The first objective of this study is to conduct a usability test of this app. The second objective is to collect users’ critical opinions on the usability and relevance of the tool. Methods We conducted a usability test by means of a think-aloud method, asking 10 representative patients to complete 7 browsing tasks. We double coded the filmed sessions to obtain descriptive data on task completion (with or without help), time spent, number of clicks, and the types of problems encountered. We assessed the severity of the problems encountered and identified the modifications needed to address these problems. We evaluated the readability of the app using Scolarius, a French equivalent of the Flesch Reading Ease test. By means of a posttest questionnaire, we asked participants to assess the app’s usability (System Usability Scale), relevance (Mobile App Rating Scale, section F), and whether they would recommend the app to the target groups: patients, health professionals, and patients’ caring relatives. Results Participants completed the 7 think-aloud tasks in 80% (56/70) of the cases without any help from the experimenter, in 16% (11/70) of the cases with some help, and failed in 4% (3/70) of the cases. The analysis of failures and difficulties encountered revealed a series of major usability problems that could be addressed with minor modifications to the app. Accordons-nous obtained high scores on readability (overall score of 87.4 on Scolarius test, corresponding to elementary school level), usability (85.3/100 on System Usability Scale test), relevance (4.3/5 on the Mobile App Rating Scale, section F), and overall subjective endorsement on 3 I would recommend questions (4.7/5). Conclusions This usability test helped us make the final changes to our app before its official launch.

Abstract
BACKGROUND Residents may learn how to perform advance care planning (ACP) through informal curriculum. Task-based instructional designs and recent international consensus statements for ACP provide opportunities to explicitly train residents, but residents' needs are poorly understood. OBJECTIVE We assessed residents' training needs in ACP at the Geneva University Hospitals in Geneva, Switzerland. METHODS Qualitative data were collected and analyzed iteratively between December 2017 and September 2019. Transcripts were coded using both a deductive content analysis based on the 4-Component Instructional Design (4C/ID) model and an inductive thematic analysis. RESULTS Out of 55 individuals contacted by email, 49 (89%) participated in 7 focus groups and 10 individual interviews, including 19 residents, 18 fellows and attending physicians, 4 nurses, 1 psychologist, 1 medical ethics consultant, 3 researchers, and 3 patients. Participants identified 3 tasks expected of residents (preparing, discussing, and documenting ACP) and discussed why training residents in ACP is complex. Participants described knowledge (eg, prognosis), skills (eg, clinical and ethical reasoning), and attitudes (eg, reflexivity) that residents need to become competent in ACP and identified needs for future training. In terms of the 4C/ID, these needs revolved around: (1) learning tasks (eg, workplace practice, simulated scenarios); (2) supportive information (eg, videotaped worked examples, cognitive feedback); (3) procedural information (eg, ACP pocket-sized information sheet, corrective feedback); and (4) part-task practice (eg, rehearsal of communication skills, simulation). CONCLUSIONS This study provides a comprehensive description of tasks and competencies to train residents in ACP.

Abstract
Pneumonia is one of the leading causes of morbidity and mortality from infection in elderly patients. The increased frequency of pneumonia among elderly subjects can be explained by the physiological changes linked to the progressive aging of the respiratory tree and the diminished immunological response. A spiral of event leads to frailty, infection and possible death; preventing pneumonia consists of controlling the risk factors. Dysphagia, which is associated with malnutrition and dehydration, is recognized as one of the major pathophysiological mechanism leading to pneumonia and its screening is crucial for the pneumonia risk assessment. The impairment in the oropharyngeal reflexes results in stagnation of foreign material in the lateral cavities of the pharynx which may then get aspirated repeatedly in the lungs and cause pneumonia. Pneumonia prevention starts with lifestyle modifications such as alcohol and tobacco cessation. A careful review of the risk-benefit of the prescribed medication is critical and adaptation may be required in elders with multiple morbidities. Respiratory physiotherapy and mobilization improve the functional status and hence may help reduce the risk of pneumonia. Maintaining teeth and masticatory efficiency is important if malnutrition and its consequences are to be avoided. Daily oral hygiene and regular professional removal of oral biofilm can prevent the onset of periodontitis and can avoid an oral environment favoring the colonization of respiratory pathogens than can then be aspirated into the lungs.

Abstract
This study aimed to translate the Interprofessional Facilitation Scale in French and validate its use for interprofessional simulation training. Experts translated the items into French and then back translated them into English. Data used for the validation were collected from interprofessional simulation trainings. Experts and observers found the scale's content validity was suitable. A principal component analysis was conducted. The Kaiser-Meyer-Olkin test value was 0.88 and two factors were identified, that explained 59.9% of the variance. They were labeled: (a) Opportunity of Interprofessional Learning and (b) Psychological Safety. The Cronbach's alpha measure of internal consistency was 0.91. The learning simulation environment explained the structure of the scale. This study provides evidence that the French version of Interprofessional Facilitation Scale can be used in the context of interprofessional simulation training.

Understanding the clinical reasoning processes involved in the management of multimorbidity in an ambulatory setting: study protocol of a stimulated recall research. BMC MEDICAL EDUCATION 2021; 21:31.

Abstract
BACKGROUND Primary care physicians are at the very heart of managing patients suffering from multimorbidity. However, several studies have highlighted that some physicians feel ill-equipped to manage these kinds of complex clinical situations. Few studies are available on the clinical reasoning processes at play during the long-term management and follow-up of patients suffering from multimorbidity. This study aims to contribute to a better understanding on how the clinical reasoning of primary care physicians is affected during follow-up consultations with these patients. METHODS A qualitative research project based on semi-structured interviews with primary care physicians in an ambulatory setting will be carried out, using the video stimulated recall interview method. Participants will be filmed in their work environment during a standard consultation with a patient suffering from multimorbidity using a "button camera" (small camera) which will be pinned to their white coat. The recording will be used in a following semi-structured interview with physicians and the research team to instigate a stimulated recall. Stimulated recall is a research method that allows the investigation of cognitive processes by inviting participants to recall their concurrent thinking during an event when prompted by a video sequence recall. During this interview, participants will be prompted by different video sequence and asked to discuss them; the aim will be to encourage them to make their clinical reasoning processes explicit. Fifteen to twenty interviews are planned to reach data saturation. The interviews will be transcribed verbatim and data will be analysed according to a standard content analysis, using deductive and inductive approaches. CONCLUSION Study results will contribute to the scientific community's overall understanding of clinical reasoning. This will subsequently allow future generation of primary care physicians to have access to more adequate trainings to manage patients suffering from multimorbidity in their practice. As a result, this will improve the quality of the patient's care and treatments.

Abstract
OBJECTIVE To determine predictors of in-hospital mortality related to COVID-19 in older patients. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS Patients aged 65 years and older hospitalized for a diagnosis of COVID-19. METHODS Data from hospital admission were collected from the electronic medical records. Logistic regression and Cox proportional hazard models were used to predict mortality, our primary outcome. Variables at hospital admission were categorized according to the following domains: demographics, clinical history, comorbidities, previous treatment, clinical status, vital signs, clinical scales and scores, routine laboratory analysis, and imaging results. RESULTS Of a total of 235 Caucasian patients, 43% were male, with a mean age of 86 ± 6.5 years. Seventy-six patients (32%) died. Nonsurvivors had a shorter number of days from initial symptoms to hospitalization (P = .007) and the length of stay in acute wards than survivors (P < .001). Similarly, they had a higher prevalence of heart failure (P = .044), peripheral artery disease (P = .009), crackles at clinical status (P < .001), respiratory rate (P = .005), oxygen support needs (P < .001), C-reactive protein (P < .001), bilateral and peripheral infiltrates on chest radiographs (P = .001), and a lower prevalence of headache (P = .009). Furthermore, nonsurvivors were more often frail (P < .001), with worse functional status (P < .001), higher comorbidity burden (P < .001), and delirium at admission (P = .007). A multivariable Cox model showed that male sex (HR 4.00, 95% CI 2.08-7.71, P < .001), increased fraction of inspired oxygen (HR 1.06, 95% CI 1.03-1.09, P < .001), and crackles (HR 2.42, 95% CI 1.15-6.06, P = .019) were the best predictors of mortality, while better functional status was protective (HR 0.98, 95% CI 0.97-0.99, P = .001). CONCLUSIONS AND IMPLICATIONS In older patients hospitalized for COVID-19, male sex, crackles, a higher fraction of inspired oxygen, and functionality were independent risk factors of mortality. These routine parameters, and not differences in age, should be used to evaluate prognosis in older patients.

Abstract
Background Age alone is not a robust predictor of mortality in critically ill elderly patients. Chronic health status and functional status before admission could be better predictors. This study aimed to determine whether functional status, assessed using the Functional Independence Measure (FIM), could be an independent predictor of mortality in a geriatric population admitted to an intermediate care unit (IMCU). Methods A monocentric, retrospective, observational study of all patients aged ≥75 years old admitted to Geneva University Hospitals’ geriatric IMCU between 01.01.2012 and 31.05.2016. The study’s primary outcome metrics were one-year mortality’s associations with a pre-admission FIM score and other relevant prospectively recorded prognostic variables. Results A total of 345 patients were included (56% female, mean age 85 +/− 6.5 years). Mean FIM score was 66 +/− 26. One-year mortality was 57%. Dichotomized low (≤ 63) and high FIM (> 63) scores were associated with one-year mortalities of 68 and 44%, respectively. Logistic regression calculations found an association between pre-admission FIM score and one-year mortality (p < 0.0001), including variables usually associated with mortality (e.g., age, sex, comorbidities, mini-mental health state score, renal function). Multivariate survival analysis showed a significant difference between groups, with a hazard ratio of 0.29 (95% CI: 0.13–0.65) for patients with high FIM scores. Conclusions In the present study, higher functional status, assessed using the FIM tool before admission to an IMCU, was significantly and independently associated with lower one-year mortality. This opens up perspectives on the potential value of FIM for establishing a finer prognosis and better triage of critically ill older patients.

Abstract
SETTING Melioidosis-Burkholderia pseudomallei infection-is increasingly recognized in Cambodia, a country with a high incidence of tuberculosis (TB). Melioidosis and TB can be clinically indistinguishable. OBJECTIVE To quantify the proportion of patients with clinically suspected TB who had melioidosis by testing sputum for B. pseudomallei. DESIGN This was a prospective, 6-month cross-sectional single-center study at a Cambodian provincial referral hospital among patients with suspicion of TB who provided sputum specimens for testing. TB was diagnosed using sputum Xpert® MTB/RIF molecular assay or culture; melioidosis was diagnosed using sputum culture for B. pseudomallei. RESULTS Of 404 patients evaluated for possible TB, 52 (12.9%, 95%CI 9.8-16.5) had TB. Four patients (1.0%, 95%CI 0.3-2.5) had melioidosis; none had concurrent TB or an existing medical risk factor for melioidosis, although two were farmers, an occupational risk factor. CONCLUSION One per cent of patients being evaluated for TB at a Cambodian provincial referral hospital had culture-proven respiratory melioidosis, a highly lethal infection. None had previously recognized medical conditions that would increase their risk of melioidosis. Testing for melioidosis should be considered in patients presenting with suspected TB in Cambodia.

Abstract
The growing range of drug resistant parasitic nematode populations threatens the sustainability of ruminant farming worldwide. In this context, nutraceuticals, animal feed that provides necessary dietary requirements while ensuring parasite control, could contribute to increase farming sustainability in developed and low resource settings. In this study, we evaluated the anthelmintic potential of lupin seed extracts against the major ruminant trichostrongylids, Haemonchus contortus and Teladorsagia circumcincta. In vitro observations showed that seed extracts from commercially available lupin varieties could significantly but moderately inhibit larval migration. This anthelmintic effect was mediated by the seed alkaloid content and was potent against both fully susceptible and multidrug resistant H. contortus isolates as well as a susceptible T. circumcincta isolate. Analytical chemistry revealed a set of four lupanine and sparteine-derivatives with anthelmintic activity, and electrophysiology assays on recombinant nematode acetylcholine receptors suggested an antagonistic mode of action for lupin alkaloids. An in vivo trial in H. contortus infected lupin-fed ewes and goats failed to demonstrate any direct anthelmintic effect of crude lupin seeds but infected lupin-fed goats suffered significantly less parasite-mediated blood losses. Altogether, our findings suggest that the anthelmintic potential of lupin remains limited. However, the potent alkaloids identified could lead to the development of novel drugs or may be used in combination with current anthelmintics to improve their efficacy.

Divergent selection on milk somatic cell count in goats improves udder health and milk quality with no effect on nematode resistance. J Dairy Sci 2019; 102:5242-5253. [PMID: 30904305 DOI: 10.3168/jds.2018-15664] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Accepted: 01/11/2019] [Indexed: 12/30/2022]
Abstract
Milk somatic cell count (SCC) is commonly higher in goats than in cattle and sheep. Furthermore, the ability of milk SCC to predict mastitis is considered lower in goats than in cattle and sheep, and the relevance of somatic cell score (SCS)-based selection in this species has been questioned. To address this issue, we created 2 divergent lines of Alpine goats using artificially inseminated bucks with extreme estimated breeding values for SCS. A total of 287 goats, 158 in high- and 129 in low-SCS lines, were scrutinized for mastitis infections. We subjected 2,688 milk samples to conventional bacteriological analyses on agarose and bacterial counts were estimated for positive samples. The SCS, milk yield, fat content, and protein content were recorded every 3 wk. Clinical mastitis was systematically noted. A subset of 40 goats (20 from each line) was subsequently challenged with Haemonchus contortus and monitored for anemia (blood packed cell volume) and fecal egg counts to see if SCS-based selection had an indirect effect on resistance to gastrointestinal nematodes. Milk production traits, including milk quantity, fat content, and protein content, were similar in both goat lines. In contrast, the raw milk SCC almost doubled between the lines, with 1,542,000 versus 855,000 cells/mL in the high- and low-SCS lines, respectively. The difference in breeding value for SCS between lines was 1.65 genetic standard deviation equivalents. The Staphylococcus spp. most frequently isolated from milk were S. xylosus, S. caprae, S. epidermidis, and S. aureus. The frequency of positive bacteriology samples was significantly higher in the high-SCS line (49%) than in the low-SCS line (33%). The highest odds ratio was 3.49 (95% confidence interval: 11.95-6.25) for S. aureus. The distribution of bacterial species in positive samples between lines was comparable. The average quantity of bacteria in positive samples was also significantly higher in high-SCS goats (69 ± 80 growing colonies) than in low-SCS goats (38 ± 62 growing colonies). Clinical cases were rare and equally distributed between high- (n = 4; 2.5%) and low-SCS (n = 3; 2.3%) lines. Furthermore, the larger the amounts of bacteria in milk the higher the SCS level. Conversely, goats with repeatedly culture-negative udders exhibited the lowest SCC levels, with an average of below 300,000 cells/mL. We therefore confirmed that SCS is a relevant predictor of intramammary infection and hygienic quality of milk in goats and can be used for prophylactic purposes. After challenge with H. contortus, goats were anemic with high fecal egg counts but we found no difference between the genetic lines. This result provides initial evidence that resistance to mastitis or to gastrointestinal nematodes infections is under independent genetic regulation. Altogether, this monitoring of the goat lines indicated that SCS-based selection helps to improve udder health by decreasing milk cell counts and reducing the incidence of infection and related bacterial shedding in milk. Selection for low SCC should not affect a goat's ability to cope with gastrointestinal nematodes.

Tuberculosis and other bacterial co-infection in Cambodia: a single center retrospective cross-sectional study. BMC Pulm Med 2019; 19:60. [PMID: 30866909 PMCID: PMC6417204 DOI: 10.1186/s12890-019-0828-4] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Accepted: 03/03/2019] [Indexed: 11/30/2022] Open
Abstract
Background Cambodia, a lower middle-income country of about 16 million individuals in southeast Asia, endures a high burden of both tuberculosis and other lower respiratory infections. Differentiating tuberculosis from other causes of respiratory infection has important clinical implications yet may be challenging to accomplish in the absence of diagnostic microbiology facilities. Furthermore, co-infection of tuberculosis with other bacterial lower respiratory infections may occur. The objective of this study was to determine the prevalence and etiologies of tuberculosis and other bacterial co-infection and to analyze the clinical and radiographic characteristics of patients presenting with respiratory infection to a provincial referral hospital in Cambodia. Methods We performed a retrospective, cross-sectional analysis of laboratory and clinical data, on patients presenting with respiratory symptoms to a chest clinic of a 260-bed provincial referral hospital in Cambodia. We analyzed mycobacterial and bacterial sputum test results, and demographics, medical history and chest radiography. Results Among 137 patients whose treating clinicians ordered sputum testing for tuberculosis and other bacteria, the median age was 52 years, 54% were male, 3% had HIV infection, and 26% were current smokers. Nearly all had chronic respiratory symptoms (> 96%) and abnormal chest radiographs (87%). Sputum testing was positive for tuberculosis in 40 patients (30%) and for bacteria in 60 patients (44%); 13 had tuberculosis and bacterial co-infection (9% overall; 33% of tuberculosis patients). Clinical characteristics were generally similar across pulmonary infection types, although co-infection was identified in 43% of patients with one or more cavitary lesions on chest radiography. Among those with bacterial growth on sputum culture, Gram negative bacilli (Klebsiella and Pseudomonas spp.) were the most commonly isolated. Conclusions Among patients with symptoms of respiratory infections whose treating clinicians ordered sputum testing for tuberculosis and other bacteria, 9% of all patients and 33% of tuberculosis patients had tuberculosis and bacterial co-infection. Greater availability of microbiologic diagnostics for pulmonary tuberculosis and bacterial infection is critical to ensure appropriate diagnosis and management.

Abstract
RATIONALE, AIMS AND OBJECTIVES In the global context of population ageing, understanding and monitoring intensive care use by the elderly is a strategic issue. National-level data are needed to overcome sampling biases that often limit epidemiologic studies of the critically ill elderly. The objective of this study was to describe intensive care use for hospitalized elderly patients using secondary data from the French national hospital discharge database. METHOD Structured assessment of the national database coverage and accuracy; cross-sectional analysis of hospitalizations including at least one admission in an intensive care unit (ICU) for patients aged ≥ 80 years from 1 January to 31 December 2009. RESULTS In 2009, people aged ≥ 80 years accounted for 5.4% of the population but 15.3% of the 215 210 adult hospitalizations involving intensive care in France. In this elderly group, the mean age was 84.0 (± 3.56) years, and 51.6% were male. In-hospital mortality was 33.9%. The median time spent in the ICU was 3 [interquartile range (IQR), 2-8] days, the median time spent in hospital was 14 (IQR, 8-24) days and 9% of hospitalizations ended by the patient's death involved intensive care. A surgical procedure was included in 43% of hospitalizations. Medical and surgical diagnosis-related group hospitalizations were characterized by significant differences in volume, mortality, ICU days and costs. CONCLUSIONS There was marked clinical heterogeneity in the population of elderly patients hospitalized in the ICU. These data provide baseline information and prompt further studies comparing intensive care utilization across age groups, between countries and over time.

Who Am I to Decide Whether This Person Is to Die Today? Physicians' Life-or-Death Decisions for Elderly Critically Ill Patients at the Emergency Department-ICU Interface: A Qualitative Study. Ann Emerg Med 2015; 68:28-39.e3. [PMID: 26619758 DOI: 10.1016/j.annemergmed.2015.09.030] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2015] [Revised: 09/19/2015] [Accepted: 09/29/2015] [Indexed: 12/20/2022]
Abstract
STUDY OBJECTIVE We explored physicians' perceptions of and attitudes toward triage and end-of-life decisions for elderly critically ill patients at the emergency department (ED)-ICU interface. METHODS This was a qualitative study with thematic analysis of data collected through semistructured interviews (15 emergency physicians and 9 ICU physicians) and nonparticipant observations (324 hours, 8 units, in 2 hospitals in France). RESULTS Six themes emerged: (1) Physicians revealed a representation of elderly patients that comprised both negative and positive stereotypes, and expressed the concept of physiologic age. (2) These age-related factors influenced physicians' decisionmaking in resuscitate/not resuscitate situations. (3) Three main communication patterns framed the decisions: interdisciplinary decisions, decisions by 2 physicians on their own, and unilateral decisions by 1 physician; however, some physicians avoided decisions, facing uncertainty and conflicts. (4) Conflicts and communication gaps occurred at the ED-ICU interface and upstream of the ED-ICU interface. (5) End-of-life decisions were perceived as more complex in the ED, in the absence of family or of information about elderly patients' end-of-life preferences, and when there was conflict with relatives, time pressure, and a lack of training in end-of-life decisionmaking. (6) During decisionmaking, patients' safety and quality of care were potentially compromised by delayed or denied intensive care and lack of palliative care. CONCLUSION These qualitative findings highlight the cognitive heuristics and biases, interphysician conflicts, and communication gaps influencing physicians' triage and end-of-life decisions for elderly critically ill patients at the ED-ICU interface and suggest strategies to improve these decisions.

Abstract
Background Evidence-based public health requires that research provides policymakers with reliable and accessible information reflecting the disease threats. We described the scientific production of research in Cambodia and assessed to what extent it provides appropriate insights and implications for practice to guide health policymakers and managers and knowledge relevant for translation. Methods We conducted a systematic review of scientific articles published on biomedical research in Cambodia. Regression analysis assessed the trends over time and factors associated with actionable messages in the articles’ abstracts. Results From 2000 to 2012, 628 articles were published in 237 journals with a significant increase over time (from 0.6/million population to 5.9/million population, slope coefficient 7.6, 95% CI 6.5–8.7, p < 0.001). Most publications on diseases addressed communicable diseases (n = 410, 65.3%). Non-communicable diseases (NCD) were under-addressed (7.7% of all publications) considering their burden (34.5% of the disease burden). Of all articles, 67.8% reported descriptive studies and 4.3% reported studies with a high level of evidence; 27.4% of studies were led by an institution based in Cambodia. Factors associated with an actionable message (n = 73, 26.6%) were maternal health (OR 3.08, 95% CI 1.55–6.13, p = 0.001), the first author’s institution being Cambodian (OR 1.78, 95% CI 1.06–2.98, p = 0.02) and a free access to full article (OR 3.07, 95% CI 1.08–8.70, p = 0.03). Of all articles, 87% (n = 546) were accessible in full text from Cambodia. Conclusions Scientific publications do not fully match with health priorities. Gaps remain regarding NCD, implementation studies, and health system research. A health research agenda would help align research with health priorities. We recommend 1) that the health authorities create an online repository of research findings with abstracts in the local language; 2) that academics emphasize the importance of research in their university teaching; and 3) that the researcher teams involve local researchers and that they systematically provide a translation of their abstracts upon submission to a journal. We conclude that building the bridge between research and public health requires a willful, comprehensive strategy rather than relying solely only publications.

Abstract
OBJECTIVES Community-acquired pneumonia (CAP) is one of the most important causes of morbidity and mortality worldwide. Etiological data for Cambodia is scarce. We aimed to describe the main etiological agents causing CAP, and their resistance patterns in Cambodia and the greater Mekong region. METHODS A review of bacterial etiologies of CAP and antimicrobial resistance in Cambodia and neighboring countries was conducted via: (1) a systematic review of published literature in all NCBI databases using Pubmed, Google scholar, EMBASE, the World Health Organization and the Cambodian Ministry of Health libraries; (2) a review of unpublished data from Cambodia provided by national and international stakeholders working at different tiers of the healthcare system. RESULTS Twenty three articles and five data sources reported etiologies for 5919 CAP patients diagnosed between May 1995 and December 2012, including 1421 (24.0%), 3571 (60.3%) and 927 (15.7%) from Cambodia, Thailand and Vietnam, respectively. Streptococcus pneumoniae and Haemophilus influenzae were the most common pathogens ranking among the five most prevalent in 12 and 10 studies, respectively. Gram-negative bacteria such as Burkholderia pseudomallei and Klebsiella pneumoniae were also frequently diagnosed, particularly in bacteremic CAP in Thai adults and Cambodian children. In Thailand and Vietnam, Mycoplasma pneumoniae and Chlamydia pneumoniae were frequently identified in settings using indirect laboratory testing. CONCLUSIONS Based on this analysis, CAP data in Cambodia seems to present etiological and resistance profiles comparable to those of neighboring countries. Findings have been shared with the national authorities upon the revision of the national therapeutic guidelines and were disseminated using a specially created website.

Abstract
INTRODUCTION Muscle phosphofructokinase deficiency, the seventh member of the glycogen storage diseases family, is also called Tarui's disease (GSD VII). METHODS We studied two patients in two unrelated families with Tarui's disease, analyzing clinical features, CK level, EMG, muscle biopsy findings and molecular genetics features. Metabolic muscle explorations (forearm ischemic exercise test [FIET]; bicycle ergometer exercise test [EE]; 31P-nuclear magnetic resonance spectroscopy of calf muscle [31P-NMR-S]) are performed as appropriate. RESULTS Two patients, a 47-year-old man and a 38-year-old woman, complained of exercise-induced fatigue since childhood. The neurological examination was normal or showed light weakness. Laboratory studies showed increased CPK, serum uric acid and reticulocyte count without anemia. There was no increase in the blood lactate level during the FIET or the EE although there was a light increase in the respiratory exchange ratio during the EE. 31P-NMR-S revealed no intracellular acidification or accumulated intermediates such as phosphorylated monoesters (PME) known to be pathognomic for GSD VII. Two new mutations were identified. DISCUSSION FIET and EE were non-contributive to diagnosis, but 31P-NMR provided a characteristic spectra of Tarui's disease, in agreement with phosphofructokinase activity level in erythrocytes. Muscle biopsy does not always provide useful information for diagnosis. In these two cases, genetic studies failed to establish a genotype-phenotype correlation. CONCLUSION The search for phosphofructokinase deficiency should be continued throughout life in adults experiencing fatigability or weakness because of the severe disability for daily life activities caused by the late onset form.

Abstract
BACKGROUND The prospective, randomized, open, blinded endpoint evaluation (PROBE) design has been proposed as a valid alternative to the double-blind (DB) design for trials comparing new oral anticoagulants (NOAs) with INR-adjusted vitamin K antagonists in patients with non-valvular atrial fibrillation (NVAF). OBJECTIVES To determine whether the observed treatment effects of NOAs in patients with NVAF differ between PROBE/open-label trials and DB trials. METHODS All phase II or III trials were eligible. The main efficacy and safety outcomes were stroke/systemic embolism (SSE) and major bleeding, respectively. Other outcomes included ischemic SSE, hemorrhagic stroke, intracranial and extracranial bleeding, myocardial infarction, and all-cause and cardiovascular mortality. Interaction (Cochran's chi-squared test) between PROBE and DB designs was tested. RESULTS Thirteen studies (61 620 patients) were included. For SSE, a greater treatment effect of NOAs vs. INR-adjusted warfarin was observed in PROBE trials (RR 0.76, CI 0.65-0.89) compared with DB trials (RR 0.88, CI 0.78-0.98), but the interaction test was non-significant (P = 0.16). A significant 67% enhancement of treatment effect was found with PROBE/open-label trials compared with DB trials (interaction test, P = 0.05) for hemorrhagic stroke. No other interaction was significant. A non-significant interaction (P = 0.07) between oral direct thrombin inhibitors (RR 0.33; 0.22-0.51) and factor Xa inhibitors (RR 0.54; 0.40-0.72) was seen. No heterogeneity was found for any outcome. CONCLUSIONS Our meta-analysis showed no significant interaction of study design for the main efficacy and safety outcomes. However, the non-significantly exaggerated reduction in SSE suggests interdependence of treatment effect and PROBE design, especially for hemorrhagic stroke.

Abstract
OBJECTIVE To estimate the morbidity and mortality conferences (MMC) impact in intensive care unit (ICU) setting on quality of care and patients' safety. DATA SOURCES A review of English and French articles in Medline database (1990-2011) related to MMC in the ICU. Keywords used: "morbidity (and) mortality conference(s)", "intensive care unit", "intensive/critical care medicine". Additional studies identified by hand search in French national guidelines about MMCs and in the Annales Françaises d'Anesthésie Réanimation and Réanimation journals index. Identification and preliminary analysis performed using title and abstract, for every study related to MMC in the ICU. STUDY SELECTION Only original studies about MMC in the ICU setting that reported an assessment were included. Papers reporting guidelines and methods for MMC implementation were excluded. DATA EXTRACTION Extraction used predefined data fields, including study design, MMC characteristics, assessment methods and results. DATA SYNTHESIS Studies about MMC in the ICU are recent and scarce. Results comparison and synthesis are impaired by discrepancies in study designs. Although the effectiveness of MMC is not evidence-based, data are consistent for their positive impact on quality of care and patient safety in the ICU. CONCLUSION Further studies are required to assess the impact of MMC in the ICU. Based on this literature review, a 4-level evaluation scheme can be suggested: 1) evaluation of MMC implementation in care units and facilities; 2) evaluation of MMC organization; 3) evaluation of MMC on quality of care; 4) evaluation of MMC impact on patients' mortality and morbidity.

Abstract
Background Postoperative delirium is common in the elderly and is associated with a significant increase in mortality, complications, length of hospital stay and admission in long care facility. Although several interventions have proved their effectiveness to prevent it, the Cochrane advises an assessment of multifaceted intervention using rigorous methodology based on randomized study design. Our purpose is to present the methodology and expected results of the CONFUCIUS trial, which aims to measure the impact of a multifaceted program on the prevention of postoperative delirium in elderly. Method/Design Study design is a stepped wedge cluster randomized trial within 3 surgical wards of three French university hospitals. All patients aged 75 and older, and admitted for scheduled surgery will be included. The multifaceted program will be conducted by mobile geriatric team, including geriatric preoperative consultation, training of the surgical staff and implementation of the Hospital Elder Life Program, and morbidity and mortality conference related to delirium cases. The primary outcome is based on postoperative delirium rate within 7 days after surgery. This program is planned to be implemented along four successive time periods within all the surgical wards. Each one will be affected successively to the control arm and to the intervention arm of the trial and the order of program introduction within each surgical ward will be randomly assigned. Based on a 20% reduction of postoperative delirium rate (ICC = 0.25, α = 0.05, β = 0.1), three hundred sixty patients will be included i.e. thirty patients per service and per time period. Endpoints comparison between intervention and control arms of the trial will be performed by considering the cluster and time effects. Discussion Better prevention of delirium is expected from the multifaceted program, including a decrease of postoperative delirium, and its consequences (mortality, morbidity, postoperative complications and length of hospital stay) among elderly patients. This study should allow better diagnosis of delirium and strengthen the collaboration between surgical and mobile geriatric teams. Should the program have a substantial impact on the prevention of postoperative delirium in elderly, it could be extended to other facilities. Trial registration ClinicalTrials.gov: NCT01316965

Abstract
We report a 39-year-old woman with systemic lupus who presented with recurrent aseptic meningitis secondary to treatment with nonsteroidal anti-inflammatory drugs (NSAIDs). She presented two episodes following ibuprofen administration that were characterized by aseptic meningitis with high protein level in cerebrospinal fluid, and increased serum acute phase reactants. No evidence of an infection or vasculitis was documented. Clinical manifestation resolved rapidly with ibuprofen discontinuation, and corticosteroids therapy was unnecessary. Aseptic meningitis related to NSAIDs reported in lupus patients should be considered because of their specific modality of care and their favourable outcome.

Abstract
Bronchodilators are frequently used in ICU patients, and are the most common medications administered by inhalation during mechanical ventilation. The amount of bronchodilator that deposits at its site of action depends on the amount of drug, inhaled mass, deposited mass, and particle size distribution. Mechanical ventilation challenges both inhaled mass and lung deposition by specific features, such as a ventilatory circuit, an endotracheal tube, and ventilator settings. Comprehensive in vitro studies have shown that an endotracheal tube is not as significant a barrier for the drug to travel as anticipated. Key variables of drug deposition are attachments of the inhalation device in the inspiratory line 10 to 30 cm to the endotracheal tube, use of chamber with metered-dose inhaler, dry air, high tidal volume, low respiratory frequency, and low inspiratory flow, which can increase the drug deposition. In vivo studies showed that a reduction by roughly 15% of the respiratory resistance was achieved with inhaled bronchodilators during invasive mechanical ventilation. The role of ventilatory settings is not as clear in vivo, and primary factors for optimal delivery and physiologic effects were medication dose and device location. Nebulizers and pressurized metered-dose inhalers can equally achieve physiologic end points. The effects of bronchodilators should be carefully evaluated, which can easily be done with the interrupter technique. With the non-invasive ventilation, the data regarding drug delivery and physiologic effects are still limited. With the bilevel ventilators the inhalation device should be located between the leak port and face mask. Further studies should investigate the effects of inhaled bronchodilators on patient outcome and methods to optimize delivery of inhaled bronchodilators during non-invasive ventilation.

Abstract
RATIONALE Providing family members with clear, honest, and timely information is a major task for intensive care unit physicians. Time spent informing families has been associated with effectiveness of information but has not been measured in specifically designed studies. OBJECTIVES To measure time spent informing families of intensive care unit patients. METHODS One-day cross-sectional study in 90 intensive care units in France. MEASUREMENTS Clocked time spent by physicians informing the families of each of 951 patients hospitalized in the intensive care unit during a 24-hr period. MAIN RESULTS Median family information time was 16 (interquartile range, 8-30) mins per patient, with 20% of the time spent explaining the diagnosis, 20% on explaining treatments, and 60% on explaining the prognosis. One third of the time was spent listening to family members. Multivariable analysis identified one factor associated with less information time (room with more than one bed) and seven factors associated with more information time, including five patient-related factors (surgery on the study day, higher Logistic Organ Dysfunction score, coma, mechanical ventilation, and worsening clinical status) and two family-related factors (first contact with family and interview with the spouse). Median information time was 20 (interquartile range, 10-39) mins when three factors were present and 106.5 (interquartile range, 103-110) mins when five were present. CONCLUSION This study identifies factors associated with information time provided by critical care physicians to family members of critically ill patients. Whether information time correlates with communication difficulties or communication skills needs to be evaluated. Information time provided by residents and nurses should be studied.

Abstract
PURPOSE OF REVIEW Care surrounding end-of-life has become a major topic in the intensive care medicine literature. Cultural and regional variations are associated with transatlantic debates about decisions to forego life-sustaining therapies and lead to recent international statements. The aim of this review is to provide insight into the decisions to forego life sustaining therapies and end-of-life care in Europe. RECENT FINDINGS Although decisions to forego life-sustaining therapies are increasingly made in European countries, frequency and characteristics of end-of-life care are still heterogeneous. Moreover, even though many determinants of these variations have been identified, epidemiologic and interventional studies still provide additional information. In agreement with public opinions, recent European laws have emphasized the patient's autonomy. In real life, advance care planning is rarely used. Decisions are often made by caregivers (physicians and nurses) or families, these latter being less involved than in North America. Not only ethic divergences between physicians but also cultural variations account for this disparity. SUMMARY To optimize end-of-life care in the intensive care unit, there is an urgent need for the development of palliative and multidisciplinary care in Europe. Furthermore, it highlights the need for culturally competent care, adapted to needs and values of every single patient and family. In addition, a lack of communication with families and within the medical team, an uninformed public about end-of-life issues, and insufficient training of intensive care unit staff are crucial barriers to end-of-life care development. Special awareness of professionals and innovative research are needed to promote a high-standard of end-of-life care in the intensive care unit.

Abstract
STUDY OBJECTIVES More than two thirds of family members visiting intensive care unit (ICU) patients have symptoms of anxiety or depression during the first days of hospitalization. Identifying determinants of these symptoms would help caregivers support families at patient discharge or when death is imminent. DESIGN AND SETTING Prospective multicenter study including 78 ICUs (1184 beds) in France. PARTICIPANTS Family members completed the Hospital Anxiety and Depression Scale on the day of patient discharge or death to allow evaluation of the prevalence and potential factors associated with symptoms of anxiety and depression. RESULTS Three hundred fifty-seven patients were included in the study, and 544 family members completed the Hospital Anxiety and Depression Scale. Symptoms of anxiety and depression were found in 73.4% and 35.3% of family members, respectively; 75.5% of family members and 82.7% of spouses had symptoms of anxiety or depression (P = .007). Symptoms of depression were more prevalent in family members of nonsurvivors (48.2%) than of survivors (32.7%) (P = .008). The multivariate model identified 3 groups of factors associated with symptoms: (1) patient-related: severity as assessed by the Simplified Acute Physiology Score II (odds ratio [OR] 1.017 per point) and patient age (OR 0.984 per year) predicted anxiety, and Simplified Acute Physiology Score II (OR, 1.015 per point), patient death (OR 2.092), and patient age (OR 0.981) predicted depression; (2) family-related: the spouse predicted anxiety (OR 2.085); and (3) ICU-related: a room with more than 1 bed (OR 1.539) predicted depression. CONCLUSION The prevalence of symptoms of anxiety and depression remains high at the end of the ICU stay, whether the patient is well enough to be discharged or is near death.

Abstract
RATIONALE Intensive care unit (ICU) admission of a relative is a stressful event that may cause symptoms of post-traumatic stress disorder (PTSD). OBJECTIVES Factors associated with these symptoms need to be identified. METHODS For patients admitted to 21 ICUs between March and November 2003, we studied the family member with the main potential decision-making role. MEASUREMENTS Ninety days after ICU discharge or death, family members completed the Impact of Event Scale (which evaluates the severity of post-traumatic stress reactions), Hospital Anxiety and Depression Scale, and 36-item Short-Form General Health Survey during a telephone interview. Linear regression was used to identify factors associated with the risk of post-traumatic stress symptoms. MAIN RESULTS Interviews were obtained for family members of 284 (62%) of the 459 eligible patients. Post-traumatic stress symptoms consistent with a moderate to major risk of PTSD were found in 94 (33.1%) family members. Higher rates were noted among family members who felt information was incomplete in the ICU (48.4%), who shared in decision making (47.8%), whose relative died in the ICU (50%), whose relative died after end-of-life decisions (60%), and who shared in end-of-life decisions (81.8%). Severe post-traumatic stress reaction was associated with increased rates of anxiety and depression and decreased quality of life. CONCLUSION Post-traumatic stress reaction consistent with a high risk of PTSD is common in family members of ICU patients and is the rule among those who share in end-of-life decisions. Research is needed to investigate PTSD rates and to devise preventive and early-detection strategies.
