Swiss Interdisciplinary Management Programme for Heart Failure (SWIM-HF): a randomised controlled trial study of an outpatient inter-professional management programme for heart failure patients in Switzerland.

PRINCIPLES: International guidelines for heart failure (HF) care recommend the implementation of inter-professional disease management programmes. To date, no such programme has been tested in Switzerland. The aim of this randomised controlled trial (RCT) was to test the effect on hospitalisation, mortality and quality of life of an adult ambulatory disease management programme for patients with HF in Switzerland.METHODS: Consecutive patients admitted to internal medicine in a Swiss university hospital were screened for decompensated HF. A total of 42 eligible patients were randomised to an intervention (n = 22) or usual care group (n = 20). Medical treatment was optimised and lifestyle recommendations were given to all patients. Intervention patients additionally received a home visit by a HF-nurse, followed by 17 telephone calls of decreasing frequency over 12 months, focusing on self-care. Calls from the HF nurse to primary care physicians communicated health concerns and identified goals of care. Data were collected at baseline, 3, 6, 9 and 12 months. Mixed regression analysis (quality of life) was used. Outcome assessment was conducted by researchers blinded to group assignment.RESULTS: After 12 months, 22 (52%) patients had an all-cause re-admission or died. Only 3 patients were hospitalised with HF decompensation. No significant effect of the intervention was found on HF related to quality of life.CONCLUSIONS: An inter-professional disease management programme is possible in the Swiss healthcare setting but effects on outcomes need to be confirmed in larger studies.

Characteristics and determinants of outcome of hospital-acquired bloodstream infections in intensive care units: the EUROBACT International Cohort Study.

PURPOSE: The recent increase in drug-resistant micro-organisms complicates the management of hospital-acquired bloodstream infections (HA-BSIs). We investigated the epidemiology of HA-BSI and evaluated the impact of drug resistance on outcomes of critically ill patients, controlling for patient characteristics and infection management. METHODS: A prospective, multicentre non-representative cohort study was conducted in 162 intensive care units (ICUs) in 24 countries. RESULTS: We included 1,156 patients [mean ± standard deviation (SD) age, 59.5 ± 17.7 years; 65 % males; mean ± SD Simplified Acute Physiology Score (SAPS) II score, 50 ± 17] with HA-BSIs, of which 76 % were ICU-acquired. Median time to diagnosis was 14 [interquartile range (IQR), 7-26] days after hospital admission. Polymicrobial infections accounted for 12 % of cases. Among monomicrobial infections, 58.3 % were gram-negative, 32.8 % gram-positive, 7.8 % fungal and 1.2 % due to strict anaerobes. Overall, 629 (47.8 %) isolates were multidrug-resistant (MDR), including 270 (20.5 %) extensively resistant (XDR), and 5 (0.4 %) pan-drug-resistant (PDR). Micro-organism distribution and MDR occurrence varied significantly (p < 0.001) by country. The 28-day all-cause fatality rate was 36 %. In the multivariable model including micro-organism, patient and centre variables, independent predictors of 28-day mortality included MDR isolate [odds ratio (OR), 1.49; 95 % confidence interval (95 %CI), 1.07-2.06], uncontrolled infection source (OR, 5.86; 95 %CI, 2.5-13.9) and timing to adequate treatment (before day 6 since blood culture collection versus never, OR, 0.38; 95 %CI, 0.23-0.63; since day 6 versus never, OR, 0.20; 95 %CI, 0.08-0.47). CONCLUSIONS: MDR and XDR bacteria (especially gram-negative) are common in HA-BSIs in critically ill patients and are associated with increased 28-day mortality. Intensified efforts to prevent HA-BSIs and to optimize their management through adequate source control and antibiotic therapy are needed to improve outcomes.

The region makes the difference: disparities in management of acute myocardial infarction within Switzerland.

BACKGROUND: In Switzerland, health policies are decided at the local level, but little is known regarding their impact on the management of acute myocardial infarction (AMI). In this study, we assessed geographical differences within Switzerland regarding management of AMI. DESIGN: Cross-sectional study. METHODS: Swiss hospital discharge database for period 2007-2008 (26,204 discharges from AMI). Seven Swiss regions (Leman, Mittelland, Northwest, Zurich, Central, Eastern, and Ticino) were analysed. RESULTS: Almost 53.7% of discharges from AMI were managed in a single hospital, ranging from 62.1% (Leman) to 31.6% (Ticino). The highest intensive care unit admission rate was in Leman (69.4%), the lowest (16.9%) in Ticino (Swiss average: 36.0%). Intracoronary revascularization rates were highest in Leman (51.1%) and lowest (30.9%) in Central Switzerland (average: 41.0%). Bare (non-drug-eluting) stent use was highest in Leman (61.4%) and lowest (16.9%) in Ticino (average: 42.1%), while drug-eluting stent use was highest (83.2%) in Ticino and lowest (38.6%) in Leman (average: 57.9%). Coronary artery bypass graft rates were highest (4.8%) in Ticino and lowest (0.5%) in Eastern Switzerland (average: 2.8%). Mechanical circulatory assistance rates were highest (4.2%) in Zurich and lowest (0.5%) in Ticino (average: 1.8%). The differences remained after adjusting for age, single or multiple hospital management, and gender. CONCLUSIONS: In Switzerland, significant geographical differences in management and revascularization procedures for AMI were found.

Three years of haemovigilance in a general university hospital.

The aim of this study is to describe a newly implemented haemovigilance system in a general university hospital. We present a series of short cases, highlighting particular aspects of the reports, and an overview of all reported incidents between 1999 and 2001. Incidents related to transfusion of blood products were reported by the clinicians using a standard preformatted form, giving a synopsis of the incident. After analysis, we distinguished, on the one hand, transfusion reactions, that are transfusions which engendered signs or symptoms, and, on the other hand, the incidents where management errors and/or dysfunctions took place. Over 3 years, 233 incidents were reported, corresponding to 4.2 events for 1000 blood products delivered. Of the 233, 198 (85%) were acute transfusion reactions and 35 (15%) were management errors and/or dysfunctions. Platelet units gave rise to statistically (P < 0.001) more transfusion reactions (10.7 per thousand ) than red blood cells (3.5 per thousand ) and fresh frozen plasma (0.8 per thousand ), particularly febrile nonhaemolytic transfusion reactions and allergic reactions. A detailed analysis of some of the transfusion incident reports revealed complex deviations and/or failures of the procedures in place in the hospital, allowing the implementation of corrective and preventive measures. Thus, the haemovigilance system in place in the 'Centre Hospitalier Universitaire Vaudois, CHUV' appears to constitute an excellent instrument for monitoring the security of blood transfusion.

Pancreatic stone protein as an early biomarker predicting mortality in a prospective cohort of patients with sepsis requiring ICU management.

ABSTRACT: INTRODUCTION: Biomarkers, such as C-reactive protein [CRP] and procalcitonin [PCT], are insufficiently sensitive or specific to stratify patients with sepsis. We investigate the prognostic value of pancreatic stone protein/regenerating protein (PSP/reg) concentration in patients with severe infections. METHODS: PSP/reg, CRP, PCT, tumor necrosis factor-alpha (TNF-&#945;), interleukin 1 beta (IL1-&#946;), IL-6 and IL-8 were prospectively measured in cohort of patients &#8805; 18 years of age with severe sepsis or septic shock within 24 hours of admission in a medico-surgical intensive care unit (ICU) of a community and referral university hospital, and the ability to predict in-hospital mortality was determined. RESULTS: We evaluated 107 patients, 33 with severe sepsis and 74 with septic shock, with in-hospital mortality rates of 6% (2/33) and 25% (17/74), respectively. Plasma concentrations of PSP/reg (343.5 vs. 73.5 ng/ml, P < 0.001), PCT (39.3 vs. 12.0 ng/ml, P < 0.001), IL-8 (682 vs. 184 ng/ml, P < 0.001) and IL-6 (1955 vs. 544 pg/ml, P < 0.01) were significantly higher in patients with septic shock than with severe sepsis. Of note, median PSP/reg was 13.0 ng/ml (IQR: 4.8) in 20 severely burned patients without infection. The area under the ROC curve for PSP/reg (0.65 [95% CI: 0.51 to 0.80]) was higher than for CRP (0.44 [0.29 to 0.60]), PCT 0.46 [0.29 to 0.61]), IL-8 (0.61 [0.43 to 0.77]) or IL-6 (0.59 [0.44 to 0.75]) in predicting in-hospital mortality. In patients with septic shock, PSP/reg was the only biomarker associated with in-hospital mortality (P = 0.049). Risk of mortality increased continuously for each ascending quartile of PSP/reg. CONCLUSIONS: Measurement of PSP/reg concentration within 24 hours of ICU admission may predict in-hospital mortality in patients with septic shock, identifying patients who may benefit most from tailored ICU management.

Haemorrhage into the pancreatic duct (Hemosuccus pancreaticus): recognition and management.

OBJECTIVE: To highlight the clinical presentation, investigation and treatment of haemorrhage into the pancreatic duct. DESIGN: Retrospective study and review of publications. SETTING: University hospital, Switzerland. SUBJECTS: All 4 cases from 1972 to 1993. INTERVENTIONS: 2 Whipple procedures, 1 resection of the pancreatic head, 1 exploratory laparotomy. Radiological embolisation in one case. MAIN OUTCOME MEASURES: Cessation of haemorrhage and survival. RESULTS: The diagnosis was made preoperatively in three cases by gastroduodenoscopy and arteriography. Operation was the primary treatment in all patients and was effective with low morbidity and no mortality in three of them. Embolisation stopped the haemorrhage in the fourth patient, who was alcoholic and died of progressive liver insufficiency and variceal haemorrhage. CONCLUSIONS: There is no specific indication for haemorrhage into the pancreatic duct. The diagnosis is suggested by endoscopy (absence of a more common cause, or blood in the second part of the duodenum). Arteriography is essential to confirm the site of the bleeding and to attempt embolization. Operation is usually the definitive treatment.

Patient dose management in fluoroscopy : the use of DRL : P123

Purpose: To set local dose reference levels (DRL) that allow radiologists to control stochastic and deterministic effects. Methods and materials: Dose indicators for cerebral angiographies and hepatic embolizations were collected during 4 months and analyzed in our hospital. The data were compared when an image amplifier was used instead of a flat panel detector. The Mann and Whitney test was used. Results: For the 40 cerebral angiographies performed the DRL for DAP, fluoroscopy time and number of images were respectively: 166 Gy.cm2, 19 min, 600. The maximum DAP was 490 Gy.cm2 (fluoroscopy time: 84 min). No significant difference for fluoroscopy time and DAP for image amplifier and flat panel detector (p = 0.88) was observed. The number of images was larger for flat panel detector (p = 0.004). The values obtained were slightly over the present proposed DRL: 150 Gy.cm2, 15 min, 400. Concerning the 13 hepatic embolizations the DRL for DAP fluoroscopy time and number of images were: 315 Gy.cm2, 25 min, 370. The maximum DAP delivered was 845 Gy.cm2 (fluoroscopy time of 48 min). No significant difference between image amplifier and flat panel detector was observed (p = 0.005). The values obtained were also slightly over the present proposed DRL: 300 Gy.cm2, 20 min, 200. Conclusion: These results show that the introduction of flat panel detector did not lead to an increase in patient dose. A DRL concerning the cumulative dose (that allow to control the deterministic effect) should be introduced to allow radiologists to have full control on the risks associated with ionizing radiations. Results of this on going study will be presented.

The role of computational fluid dynamics in the management of unruptured intracranial aneurysms: a clinicians' view

Objective: The importance of hemodynamics in the etiopathogenesis of intracranial aneurysms (IAs) is widely accepted.Computational fluid dynamics (CFD) is being used increasingly for hemodynamic predictions. However, alogn with thecontinuing development and validation of these tools, it is imperative to collect the opinion of the clinicians. Methods: A workshopon CFD was conducted during the European Society of Minimally Invasive Neurological Therapy (ESMINT) Teaching Course,Lisbon, Portugal. 36 delegates, mostly clinicians, performed supervised CFD analysis for an IA, using the @neuFuse softwaredeveloped within the European project @neurIST. Feedback on the workshop was collected and analyzed. The performancewas assessed on a scale of 1 to 4 and, compared with experts’ performance. Results: Current dilemmas in the management ofunruptured IAs remained the most important motivating factor to attend the workshop and majority of participants showedinterest in participating in a multicentric trial. The participants achieved an average score of 2.52 (range 0–4) which was 63% (range 0–100%) of an expert user. Conclusions: Although participants showed a manifest interest in CFD, there was a clear lack ofawareness concerning the role of hemodynamics in the etiopathogenesis of IAs and the use of CFD in this context. More effortstherefore are required to enhance understanding of the clinicians in the subject.

Taking care of the most vulnerable : a descriptive study of patients with 12 attendances or more at a Swiss university hospital emergency department in 2009

Introduction: Patients who repeatedly attend the Emergency Department (ED) often have a distinct and complex vulnerability profile that includes poor somatic, psychological, and social indicators. This profile has an impact on the patients' well-being as well as on hospital costs. The objective of the study was to specify the characteristics of hyper users (HU) and explore the connection with ED care and hospital costs. Methods: The study sample comprised all adult patients with 12 or more attendances at the ED of the Lausanne University Hospital in 2009. The data were collected by retrospectively searching internal databases to identify the patients concerned and then analysing the profiles of these patients. Information gathered included demographic, somatic, psychological, at-risk behaviour, and social indicators, and health system consumption including costs. Results: In 2009, 23 patients (0.1%) attended 12 times or more (425 attendances, 0.8%). The average age was about 43 years, 60.9% were female, and 47.8% single. Of these 95.7% had basic insurance, 87.0% had a general practitioner, and 30.4% were under legal guardianship. The majority attended in the evening or at night (67.1%), and almost one quarter of these attendances resulted in inpatient treatment (24.0%). Most HU had attended the ED in previous years too (95.7% in 2008). The most prevalent diagnoses concerned 'mental disorders' (87.0%). About 30.4% of patients had attempted suicide (all were female patients). Other frequent diagnoses concerned 'trauma' (65.2%), and the 'digestive' and the 'nervous system' (each 56.5%). At-risk behaviour such as severe alcohol consumption (34.8%), or excessive use of medicines (26.1%) was very frequent, and some patients used illicit drugs (21.7%). There was only a weak association between the number of ED attendances and the resulting costs. However, a reduction of one outpatient visit per patient would have decreased ED outpatient costs by 8.5%. Conclusions: HU often have a particularly vulnerable profile. Mental problems are prevalent among them, as are at-risk behaviour and severe somatic conditions. The complexity of the patients' profiles demands specific care that cannot be guaranteed within an everyday ED routine. The use of an interdisciplinary case management team might be a promising approach in diminishing the number of attendances and the associated costs, although the profiles of HU are such that they probably cannot completely give up ED attendance.

Vacuum-assisted closure device: a useful tool in the management of severe intrathoracic infections.

Background. This study is an evaluation of the vacuum-assisted closure (VAC) therapy for the treatment of severe intrathoracic infections complicating lung resection, esophageal surgery, viscera perforation, or necrotizing pleuropulmonary infections.Methods. We reviewed the medical records of all patients treated by intrathoracic VAC therapy between January 2005 and December 2008. All patients underwent surgical debridement-decortication and control of the underlying cause of infection such as treatment of bronchus stump insufficiency, resection of necrotic lung, or closure of esophageal or intestinal leaks. Surgery was followed by intrathoracic VAC therapy until the infection was controlled. The VAC dressings were changed under general anesthesia and the chest wall was temporarily closed after each dressing change. All patients received systemic antibiotic therapy.Results. Twenty-seven patients (15 male, median age 64 years) underwent intrathoracic VAC dressings for the management of postresectional empyema (n = 8) with and without bronchopleural fistula, necrotizing infections (n = 7), and intrathoracic gastrointestinal leaks (n = 12). The median length of VAC therapy was 22 days (range 5 to 66) and the median number of VAC changes per patient was 6 (range 2 to 16). In-hospital mortality was 19% (n = 5) and was not related to VAC therapy or intrathoracic infection. Control of intrathoracic infection and closure of the chest cavity was achieved in all surviving patients.Conclusions. Vacuum-assisted closure therapy is an efficient and safe adjunct to treat severe intrathoracic infections and may be a good alternative to the open window thoracostomy in selected patients. Long time intervals in between VAC changes and short course of therapy result in good patient acceptance. (Ann Thorac Surg 2011;91:1582-90) (C) 2011 by The Society of Thoracic Surgeons

Age over 40 years increases the failure rate of non-operative management of blunt splenic injuries

Objective: Non-operative management (NOM) of blunt splenic injuries (BSI) is nowadays considered the standard treatment. The study aimed to determine the criteria applied for NOM and to identify risk factors for its failure. Methods: Review of all adult patients with BSI treated at the University Hospital Bern, Switzerland, between 2000 and 2008. Results: There were 206 patients (146 men, 70·9%) with a mean age of 38·2 ± 19·1 years and an Injury Severity Score of 30·9 ± 11·6. The American Association for the Surgery of Trauma classification of the splenic injury was: grade I, n=43 (20·9%); grade II, n=52 (25·2%); grade III, n=60 (29·1%); grade IV, n=42 (20·4%) and grade V, n=9 (4·4%). 47 patients (22·8%) required immediate surgery. Five or more units of red cell transfusions (P<0·001), Glasgow Coma Scale<11 (P=0·009) and age &#8805;55 years (P=0·038) were associated with primary operative management (OM). 159 patients (77·2%) qualified for NOM, which was successful in 89·9% (143/159). The overall splenic salvage rate was 69·4% (143/206). Multivariate analysis found age &#8805;40 years to be the only factor independently related to the failure of NOM (P=0·001). Conclusion: Advanced age is associated with an increased failure rate ofNOM in patients with BSI.

Prise en charge du patient avec bronchopneumopathie obstructive: ambulatoire ou hospitalière [Management of the patient with COPD: home case or hospitalization].

Acute exacerbation of COPD is one of the most common causes of hospital admission in patients affected with this disease. In most cases, consideration of differential diagnoses and assessment of important comorbidities will allow to make the decision whether or not the patient needs to be hospitalized. A decision to hospitalize will be based on specific symptoms and signs, as well on the patient's history. Contrary to bronchial asthma, a systematic action plan strategy is lacking for COPD. However, a disease management plan involving all the health care providers may have the potential to improve the patient's well being and to decrease costs related to these exacerbations.
