Is the process of withdrawal of life-sustaining measures in the intensive care unit different for deceased organ donors compared with other dying patients? A secondary analysis of prospectively collected data.

OBJECTIVE: To investigate whether observable differences exist between patterns of withdrawal of life-sustaining measures (WLSM) for patients eligible for donation after circulatory death (DCD) in whom donation was attempted compared with those patients in whom no donation attempts were made. SETTING: Adult intensive care units from 20 centres in Canada, the Czech Republic and the Netherlands. DESIGN: Secondary analysis of quantitative data collected as part of a large, prospective, cohort study (the Death Prediction and Physiology after Removal of Therapy study). PARTICIPANTS: Patients ≥18 years of age who died after a controlled WLSM in an intensive care unit. Patients were classified as not DCD eligible, DCD eligible with DCD attempted or DCD eligible but DCD was not attempted. PRIMARY AND SECONDARY OUTCOME MEASURES: The process of WLSM (timing and type and, if applicable, dosages of measures withdrawn, dosages of analgesics/sedatives) was compared between groups. RESULTS: Of the 635 patients analysed, 85% had either cardiovascular support stopped or were extubated immediately on WLSM. Of the DCD eligible patients, more were immediately extubated at the initiation of WLSM when DCD was attempted compared with when DCD was not attempted (95% vs 61%, p<0.0001). Initiation of WLSM with the immediate cessation of cardiovascular measures or early extubation was associated with earlier time to death, even after adjusting for confounders (OR 2.94, 95% CI 1.39 to 6.23, at 30 min). Other than in a few patients who received propofol, analgesic and sedative dosing after WLSM between DCD attempted and DCD eligible but not attempted patients was not significantly different. All patients died. CONCLUSIONS: Patients in whom DCD is attempted may receive a different process of WLSM. This highlights the need for a standardised and transparent process for end-of-life care across the spectrum of critically ill patients and potential organ donors.

Predictors of short-term and long-term mortality in critically ill patients admitted to the intensive care unit following allogeneic stem cell transplantation.

Historically, the mortality of patients admitted to the ICU after allogeneic stem cell transplantation (alloSCT) is high. Advancements in transplantation procedures, infectious monitoring and supportive care may have improved the outcome. This study aimed to determine short-term and long-term mortality after ICU admission of patients after alloSCT and to identify prognostic clinical and transplantation-related determinants present at ICU admission for long-term outcome. A multicenter cohort study was performed to determine 30-day and 1-year mortality within 2 years following alloSCT. A total of 251 patients were included. The 30-day and 1-year mortality was 55% and 80%, respectively. Platelet count <25 × 109/L (OR: 2.26, CI: 1.02-5.01) and serum bilirubin >19 µmol/L (OR: 2.47 CI: 1.08-5.65) at admission, other donor than a HLA-matched-related or HLA-matched-unrelated donor (OR: 4.59, CI: 1.49-14.1) and vasoactive medication within 24 h (OR: 2.35, CI: 1.28-4.31) were associated with increased 30-day mortality. Other donor than a HLA-matched-related or HLA-matched-unrelated donor (OR: 1.9, CI: 1.13-3.19), serum bilirubin >77 (OR: 2.05, CI: 1.28-3.30) and vasoactive medication within 24 h (OR: 1.65, CI: 1.12-2.43) were associated with increased 1-year mortality. Neutropenia was associated with decreased 30-day and 1-year mortality (OR: 0.29, CI: 0.14-0.59 and OR: 0.70, CI: 0.48-0.98). Myeloablative conditioning and T cell-depleted transplantation were not associated with increased mortality.

Working among the rural communities in Ghana - why doctors choose to engage in rural practice.

BACKGROUND: An unequal distribution of health personnel, leading to unfavourable differences in health status between urban and rural populations, is a serious cause for concern globally. Part of the solution to this problem lies in attracting medical doctors to rural, remote communities, which presents a real challenge. The present study therefore explored the factors that influence medical doctors' decision to practise in rural Ghana. METHODS: We conducted a cross-sectional descriptive study based on questionnaires. Participants were doctors working in health facilities in the districts and rural areas of the Northern Region, Ghana. The qualitative data analysis consisted of an iterative process of open, axial and selective coding. RESULTS: We administered the questionnaires to 40 doctors, 27 of whom completed and returned the form, signalling a response rate of 67.5%. The majority of the doctors were male (88.9%) and had been trained at the University for Development Studies, School of Medicine and Health Sciences (UDS-SMHS) (63%). Although they had chosen to work in the remote areas, they identified a number of factors that could prevent future doctors from accepting rural postings, such as: a lack of social amenities, financial and material resources; limited career progression opportunities; and too little emphasis on rural practice in medical school curricula. Moreover, respondents flagged specific stakeholders who, in their opinion, had a major role to play in the attraction of doctors and in convincing them to work in remote areas. CONCLUSIONS: The medical doctors we surveyed had gravitated to the rural areas themselves for the opportunity to acquire clinical skills and gain experience and professional independence. Nevertheless, they felt that in order to attract such cadre of health professionals to rural areas and retain them there, specific challenges needed addressing. For instance, they called for an enforceable, national policy on rural postings, demanding strong political commitment and leadership. Another recommendation flowing from the study findings is to extend the introduction of Community-Based Education and Service (COBES) or similar curriculum components to other medical schools in order to prepare students for rural practice, increasing the likelihood of them accepting rural postings.

Medical professionalism frameworks across non-Western cultures: A narrative overview.

BACKGROUND: Medical professionalism is context-specific, but most literature on professionalism stems from Western countries. This study is about benchmarking of different frameworks on professionalism and interpreting the commonalities and discrepancies of understanding professionalism across different cultures. We need to study the cultural underpinning of medical professionalism to graduate future "global" practitioners who are culturally sensitive enough to recognize differences (and also similarities) of expectations of patients in various contexts. AIM: This study aims at describing culture specific elements of three identified non-Western frameworks of professionalism, as well as their commonalities and differences. METHOD: A narrative overview was carried out of studies that address professionalism in non-Western cultures in the period 2002-2014. RESULTS: Out of 143 articles on medical professionalism, only four studies provided three structured professionalism frameworks in non-Western contexts. Medical professionalism attributes in non-Western cultures were influenced by cultural values. Out of the 24 identified attributes of professionalism, 3 attributes were shared by the three cultures. Twelve attributes were shared by at least two cultures, and the rest of the attributes were unique to each culture. CONCLUSIONS: The three frameworks provided culture-specific elements in a unique conceptual framework of medical professionalism according to the region they originated from. There is no single framework on professionalism that can be globally acknowledged. A culture-oriented concept of professionalism is necessary to understand what the profession is dedicated to and to incorporate the concept into the medical students' and physicians' professional identity formation.

Community-based education: The influence of role modeling on career choice and practice location.

INTRODUCTION: Research findings in medical education support the importance of positive role models in enhancing learning and influencing the career path of medical students and graduates. The authors explored the characteristics of positive and negative role models during Community-Based Education and Service (COBES), as well as their effect on trainees' career paths. METHOD: A cross-sectional survey was conducted by means of a questionnaire among medical students to explore the characteristics of positive and negative role models during COBES. Associations between gender, choice of specialty, and practice location were assessed using the chi-square test. All qualitative data analysis was performed using the principles of primary, secondary, and tertiary coding. RESULT: The majority of the students indicated that role modeling during COBES will affect their choice of specialty and practice location with a significant gender difference in terms of practice location (p < 0.005). Qualitative data supported the finding that positive role modeling during COBES may influence graduates willingness to work in rural area. CONCLUSION: The desire and willingness to work in a rural community combined with good communication and excellent interpersonal skills as well as good leadership skills are attributes of good role modeling that could influence medical students' career choice during COBES.

The perceived usefulness of community based education and service (COBES) regarding students' rural workplace choices.

BACKGROUND: Community Based Education and Service (COBES) are those learning activities that make use of the community as a learning environment. COBES exposes students to the public and primary health care needs of rural communities. The purpose of this study was to investigate students' perceived usefulness of COBES and its potential effect on their choice of career specialty and willingness to work in rural areas. METHOD: A mixed method cross sectional study design using semi-structured interviews, questionnaires, and focus group discussions were used for health facility staff, faculty and students and community members. RESULTS: One hundred and seventy questionnaires were administered to students and 134 were returned (78.8% response rate). The majority (59.7%) of students were male. Almost 45% of the students indicated that COBES will have an influence on their choice of career specialty. An almost equal number (44%) said COBES will not have an influence on their choice of career specialty. However, 60.3% of the students perceived that COBES could influence their practice location. More males (64.7%, n = 44) than females (57.8%, n = 26) were likely to indicate that COBES will influence their practice location but the differences were statistically insignificant (p = 0.553). The majority of students, who stated that COBES could influence their practice location, said that COBES may influence them to choose to practice in the rural area and that exposure to different disease conditions among different population groups may influence them in their career choice. Other stakeholders held similar views. Qualitative data supported the finding that COBES could influence medical students' choice of specialty and their practice location. CONCLUSION: Medical students' 'perceptions of the influence of COBES on their choice of career specialty were varied. However, most of the students felt that COBES could influence them to practice in rural locations.

Organ Donation After Euthanasia: A Dutch Practical Manual.

Many physicians and patients do not realize that it is legally and medically possible to donate organs after euthanasia. The combination of euthanasia and organ donation is not a common practice, often limited by the patient's underlying pathology, but nevertheless has been performed >40 times in Belgium and the Netherlands since 2005. In anticipation of patients' requests for organ donation after euthanasia and contributing to awareness of the possibility of this combination among general practitioners and medical specialists, the Maastricht University Medical Center and the Erasmus University Medical Center Rotterdam have developed a multidisciplinary practical manual in which the organizational steps regarding this combined procedure are described and explained. This practical manual lists the various criteria to fulfill and the rules and regulations the different stakeholders involved need to comply with to meet all due diligence requirements. Although an ethicist was involved in writing this paper, this report is not specifically meant to comprehensively address the ethical issues surrounding the topic. This paper is focused on the operational aspects of the protocol.

Empirical antibiotic therapy for pneumonia in intensive care units: a multicentre, retrospective analysis of potentially pathogenic microorganisms identified by endotracheal aspirates cultures.

The purpose of this investigation was to explore the presumed relationship between the days of hospitalisation and microorganisms identified by endotracheal aspirate cultures in relation to adequate empirical treatment strategies of pneumonia in the intensive care unit (ICU). All potentially pathogenic microorganisms identified by (surveillance) cultures of endotracheal aspirates obtained in the ICUs of two Dutch teaching hospitals in 2007 and 2012 were retrospectively collected and analysed. Antibiotic susceptibilities to 11 antibiotics were calculated for several time points (days or weeks) after hospital admission and expressed per patient-day. In total, 4184 potentially pathogenic microorganisms identified in 782 patients were analysed. Prevalence of the classic early-onset pneumonia-causing microorganisms decreased from 55 % on the first four days to 34 % on days 4-6 after hospital admission (p < 0.0001). Susceptibility to amoxicillin/clavulanic acid was below 70 % on all days. Except for days 0 and 12, susceptibility to ceftriaxone was below 80 %. The overall susceptibility to piperacillin/tazobactam was 1518/1973 (77 %) in 2007 vs. 727/1008 (67 %) in 2012 (p < 0.0001). After day 8 of hospital admission, susceptibility to piperacillin/tazobactam therapy was below 80 % in 2012. After one week of hospital admission, susceptibilities to antibiotics were lower in the hospital that included that antibiotic in the local empirical treatment protocols as compared to the hospitals in which that antibiotic was not or infrequently included: 90/434 (21 %) vs. 117/398 (29 %); p = 0.004 for amoxicillin/clavulanic acid and 203/433 (47 %) vs. 253/398 (64 %); p < 0.001 for ceftriaxone. No cut-off in the number of days after hospital admission could be identified to distinguish early-onset from late-onset pneumonia. Consequently, the choice of empirical antibiotics should probably not be based on the time of onset.

Mimivirus is not a frequent cause of ventilator-associated pneumonia in critically ill patients.

Acanthamoeba polyphaga mimivirus (APMV) belongs to the amoebae-associated microorganisms. Antibodies to APMV have been found in patients with pneumonia suggesting a potential role as a respiratory pathogen. In addition, positive serology for APMV was associated with an increased duration of mechanical ventilation and intensive care unit stay in patients with ventilator-associated pneumonia. The aim of the present study was to assess the presence of APMV in bronchoalveolar lavage fluid samples of critically ill patients suspected of ventilator-associated pneumonia. The study was conducted in the intensive care unit of the Maastricht University Medical Centre. All consecutive bronchoalveolar lavage fluid samples obtained between January 2005 and October 2009 from patients suspected of ventilator-associated pneumonia were eligible for inclusion. All samples were analyzed by real-time PCR targeting the APMV. A total of 260 bronchoalveolar lavage fluid samples from 214 patients (139 male, 75 female) were included. Bacterial ventilator-associated pneumonia was confirmed microbiologically in 105 out of 260 (40%) suspected episodes of ventilator-associated pneumonia (86 patients). The presence of APMV DNA could not be demonstrated in the bacterial ventilator-associated pneumonia positive or in the bacterial ventilator-associated pneumonia negative bronchoalveolar lavage fluid samples. Although suspected, APMV appeared not to be present in critically ill patients suspected of ventilator-associated pneumonia, and APMV does not seem to be a frequent cause of ventilator-associated pneumonia.

Intensive care medicine trainees' perception of professionalism: a qualitative study.

The Competency-Based Training program in Intensive Care Medicine in Europe identified 12 competency domains. Professionalism was given a prominence equal to technical ability. However, little information pertaining to fellows' views on professionalism is available. A nationwide qualitative study was performed. The moderator asked participants to clarify the terms professionalism and professional behaviour, and to explore the questions "How do you learn the mentioned aspects?" and "What ways of learning do you find useful or superfluous?". Qualitative data analysis software (MAXQDA2007) facilitated analysis using an inductive coding approach. Thirty-five fellows across eight groups participated. The themes most frequently addressed were communication, keeping distance and boundaries, medical knowledge and expertise, respect, teamwork, leadership and organisation and management. Medical knowledge, expertise and technical skills seem to become more tacit when training progresses. Topics can be categorised into themes of workplace-based learning, by gathering practical experience, by following examples and receiving feedback on action, including learning from own and others' mistakes. Formal teaching courses (e.g. communication) and scheduled sessions addressing professionalism aspects were also valued. The emerging themes considered most relevant for intensivists were adequate communication skills and keeping boundaries with patients and relatives. Professionalism is mainly learned 'on the job' from role models in the intensive care unit. Formal teaching courses and sessions addressing professionalism aspects were nevertheless valued, and learning from own and others' mistakes was considered especially useful. Self-reflection as a starting point for learning professionalism was stressed.

Successful treatment of severe bleeding with recombinant factor VIIa after kidney transplantation.

Recombinant factor VIIa (rFVIIa, NovoSeven) has been registered for the treatment of bleeding episodes in patients with inherited or acquired hemophilia A or B with inhibitors. Furthermore, rFVIIa has been used successfully for the treatment of bleeding in patients with thrombocytopenia, and acquired and congenital platelet dysfunction. The definite spectrum of indications for rFVIIa has not yet been established. We describe a case of severe intra-abdominal bleeding 3 days after non-heart beating kidney transplantation in a patient with severe coronary artery disease in which rFVIIa (a single intravenous bolus injection 70 microg/kg bodyweight) was successfully used. No thrombotic complications occurred. This report demonstrates that rFVIIa might be safe and effective after recent renal transplantation.

Clinical and immunological evaluation of primary splenic irradiation in chronic lymphocytic leukemia: a study of 24 cases.

Little is known about the effects of primary splenic irradiation (SI) in B-cell chronic lymphocytic leukemia (B-CLL) on subpopulations of lymphocytes, immunoglobulins, and the induction of autoantibodies against erythrocytes and platelets. Twenty-four untreated patients with B-CLL were studied prospectively. One patient was excluded from analysis because of intercurrent death. Of the remaining 23 patients, 7 were female and 16 were male, with an average age of 68.4 and 61.2 years, respectively. Treatment consisted of a weekly dose of I Gy up to a total dose of 10 Gy to the spleen. Standardized evaluation was done 2 weeks before and 6 weeks after SI. Twenty patients completed the course of SI. In 14 patients there was a partial response and in 9 patients the disease remained stable. The number of leukocytes decreased rapidly and significantly, with a decrease in the fraction of lymphocytes and an increase in the neutrophil count (all P<0.0001). There was a significant increase in platelet count, but not in hemoglobin level. Nausea, slight diarrhea, pleuropneumonia, granulopenia with fever (all n=1), urinary tract infection and high fever (n=1), and thrombocytopenia occurred (n=2). One patient received transfusion of packed cells because of upper digestive tract bleeding for which cessation of SI was not necessary. The number of malignant cells showed a significant decrease (P<0.01). No significant changes in CD4/CD8 ratio were found. The number of CD4+ and CD8+-cells, however, decreased significantly (P<0.01 and 0.03, respectively). DAT remained unchanged in most (93%) and tests for antibodies to platelets in 83% of the patients. No significant changes in immunoglobin levels were observed.

The outcome of esophagogastroduodenoscopy (EGD) in asymptomatic outpatients with iron deficiency anemia after a negative colonoscopy.

Background: Both iron deficiency and iron deficiency anemia require extensive investigation because of their possible association with gastrointestinal malignancy. If no other sources of blood loss are apparent, the gastrointestinal tract is examined to detect sources of occult blood loss. In the absence of gastrointestinal symptoms, the colon is first examined, especially in the elderly. The aim of this study was to determine the outcome of esophagogastroduodenoscopy (EGD) after a prior negative colonoscopy in outpatients without gastrointestinal complaints, referred due to iron deficiency anemia. Methods: Thirty-five patients (22 female and 13 male) with a median age of 71 years were studied over a 2-year period. Anemia was defined as a hemoglobin (Hb) level below 7.4 mmol/l in women or below 8.0 mmol/l in men and iron deficiency if one of the following was present: ferritin level equal to or below 20 µg/l for men and equal to or below 10 µg/l for women, a serum iron concentration equal to or below 45 µg/dl (8.1 µmol/l) with a transferrin saturation of 10% or less, or the absence of iron stores in bone marrow biopsy specimens. Patients with prior gastrointestinal disease or surgery, gastrointestinal symptoms, or other obvious causes of blood loss were excluded. Lesions that were considered to be potential sources of blood loss were clearly defined. Results: The mean Hb level of the 35 patients studied was 5.5 mmol/l (range 1.8-7.8 mmol/l). Abnormalities were found in 10 patients (28.6%), all of which were benign. Erosive and ulcerative lesions in the stomach, in a hiatal hernia, or in the esophagus were diagnosed in eight patients, benign villous adenoma was seen in one patient, and celiac disease in another, although duodenal biopsies were taken in only 15 patients. Erosions and/or ulcerations were found in four of 11 patients (36%) using NSAIDs and/or salicylates (ASA). Seventy percent of the lesions were found in elderly patients (>65 years), 56% of whom were using NSAIDs and/or ASA. Conclusions: EGD should always be performed in patients with iron deficiency anemia after a negative colonoscopy, although upper gastrointestinal malignancy will probably be an infrequent finding. The presence of a significant, treatable lesion is most likely in the elderly and in those with a history of NSAID or ASA use. Routine duodenal biopsies should be performed to further increase the outcome of EGD.

A case of herpes-like Sweet's syndrome in acute myelogenous leukemia during treatment with G-CSF.

A 49-year-old patient with refractory acute myelogenous leukemia (AML) is described who developed fever and herpes-like skin lesions during treatment with G-CSF. Skin biopsies revealed dermal neutrophilic infiltrates compatible with the diagnosis of Sweet's syndrome. The fever and skin lesions disappeared completely after treatment with corticosteroids.
