Errors in palliative care: kinds, causes, and consequences: a pilot survey of experiences and attitudes of palliative care professionals.

Abstract Background: Medical errors have recently been recognized as a relevant concern in public health, and increasing research efforts have been made to find ways of improving patient safety. In palliative care, however, studies on errors are scant. Objective: Our aim was to gather pilot data concerning experiences and attitudes of palliative care professionals on this topic. Methods: We developed a questionnaire, which consists of questions on relevance, estimated frequency, kinds and severity of errors, their causes and consequences, and the way palliative care professionals handle them. The questionnaire was sent to all specialist palliative care institutions in the region of Bavaria, Germany (n=168; inhabitants 12.5 million) reaching a response rate of 42% (n=70). Results: Errors in palliative care were regarded as a highly relevant problem (median 8 on a 10-point numeric rating scale). Most respondents experienced a moderate frequency of errors (1-10 per 100 patients). Errors in communication were estimated to be more common than those in symptom control. The causes most often mentioned were deficits in communication or organization. Moral and psychological problems for the person committing the error were seen as more frequent than consequences for the patient. Ninety percent of respondents declared that they disclose errors to the harmed patient. For 78% of the professionals, the issue was not a part of their professional training. Conclusion: Professionals acknowledge errors-in particular errors in communication-to be a common and relevant problem in palliative care, one that has, however, been neglected in training and research.

Cognitive errors assessed by observer ratings in bipolar affective disorder: relationship with symptoms and therapeutic alliance

The construct of cognitive errors is clinically relevant for cognitive therapy of mood disorders. Beck's universality hypothesis postulates the relevance of negative cognitions in all subtypes of mood disorders, as well as positive cognitions for manic states. This hypothesis has rarely been empirically addressed for patients presenting bipolar affective disorder (BD). In-patients (n = 30) presenting with BD were interviewed, as were 30 participants of a matched control group. Valid and reliable observer-rater methodology for cognitive errors was applied to the session transcripts. Overall, patients make more cognitive errors than controls. When manic and depressive patients were compared, parts of the universality hypothesis were confirmed. Manic symptoms are related to positive and negative cognitive errors. These results are discussed with regard to the main assumptions of the cognitive model for depression; thus adding an argument for extending it to the BD diagnostic group, taking into consideration specificities in terms of cognitive errors. Clinical implications for cognitive therapy of BD are suggested.

Measurement Errors Should Always Be Incorporated in Phylogenetic Comparative Analysis

The evolution of continuous traits is the central component of comparative analyses in phylogenetics, and the comparison of alternative models of trait evolution has greatly improved our understanding of the mechanisms driving phenotypic differentiation. Several factors influence the comparison of models, and we explore the effects of random errors in trait measurement on the accuracy of model selection. We simulate trait data under a Brownian motion model (BM) and introduce different magnitudes of random measurement error. We then evaluate the resulting statistical support for this model against two alternative models: Ornstein-Uhlenbeck (OU) and accelerating/decelerating rates (ACDC). Our analyses show that even small measurement errors (10%) consistently bias model selection towards erroneous rejection of BM in favour of more parameter-rich models (most frequently the OU model). Fortunately, methods that explicitly incorporate measurement errors in phylogenetic analyses considerably improve the accuracy of model selection. Our results call for caution in interpreting the results of model selection in comparative analyses, especially when complex models garner only modest additional support. Importantly, as measurement errors occur in most trait data sets, we suggest that estimation of measurement errors should always be performed during comparative analysis to reduce chances of misidentification of evolutionary processes.

Molecular epidemiology of methicillin-resistant Staphylococcus aureus in Switzerland: sampling only invasive isolates does not allow a representative description of the local diversity of clones.

We conducted a molecular study of MRSA isolated in Swiss hospitals, including the first five consecutive isolates recovered from blood cultures and the first ten isolates recovered from other sites in newly identified carriers. Among 73 MRSA isolates, 44 different double locus sequence typing (DLST) types and 32 spa types were observed. Most isolates belonged to the NewYork/Japan, the UK-EMRSA-15, the South German and the Berlin clones. In a country with a low to moderate MRSA incidence, inclusion of non-invasive isolates allowed a more accurate description of the diversity.

Epidemiologie und Prävention des Hautmelanoms in der Schweiz: Update 2010. [Epidemiology and prevention of melanoma in Switzerland: 2010 update]

Zusammenfassung] Die Inzidenz des malignen Melanoms steigt seit über 50 Jahren bei der weißen Bevölkerung stark an. Die Schweiz ist mit ungefähr 1900 neu diagnostizierten Fällen pro Jahr das am stärksten betroffene Land Europas (16/100 000 Welt-standardisierte Rate). In letzter Zeit sind regionale Unterschiede mit höherer Inzidenz in den Westschweizer Kantonen festzustellen. Änderungen in Wissen und Verhalten der Schweizer Bevölkerung gegenüber dem Schutz vor Sonnenexposition bestehen noch zu wenig lange und sind zu bescheiden, als dass sie schon einen Einfluss auf die Inzidenz hätten haben können. Dank der seit 20 Jahren betriebenen Früherfassung sind Überlebensrate und Anteil an dünnen Melanomen gestiegen, allerdings bei gleichbleibender Inzidenz dicker Läsionen. Die Mortalität aufgrund des malignen Melanoms ist neuerdings rückläufig, vor allem bei den Frauen. Werden die gegenwärtigen Präventionsbemühungen weitergeführt, dürften sich bald noch mehr Erfolge zeigen. [Abstract] The incidence of cutaneous malignant melanoma has steadily increased in Caucasian populations over the last decades. With around 1900 new cases each year, Switzerland has one of the highest melanoma rates in Europe (16/100 000 world-standardised rate). Regional differences are emerging within Switzerland, with a higher incidence in the western (French-speaking) region. Observed changes in sun protection attitudes and knowledge in the Swiss population have yet no impact on the incidence trend. Early detection, carried out since the mid 1980s in Switzerland, has led to a substantial increase in survival and rates of thin melanoma, without material change in rates of thick melanoma. Mortality from melanoma has recently decreased, earlier in women than men. The efficacy of prevention campaigns should soon become more blatant if current efforts persist.

Is trauma in Switzerland any different? epidemiology and patterns of injury in major trauma - a 5-year review from a Swiss trauma centre.

Switzerland, the country with the highest health expenditure per capita, is lacking data on trauma care and system planning. Recently, 12 trauma centres were designated to be reassessed through a future national trauma registry by 2015. Lausanne University Hospital launched the first Swiss trauma registry in 2008, which contains the largest database on trauma activity nationwide. METHODS: Prospective analysis of data from consecutively admitted shock room patients from 1 January 2008 to 31 December 2012. Shock room admission is based on physiology and mechanism of injury, assessed by prehospital physicians. Management follows a surgeon-led multidisciplinary approach. Injuries are coded by Association for the Advancement of Automotive Medicine (AAAM) certified coders. RESULTS: Over the 5 years, 1,599 trauma patients were admitted, predominantly males with a median age of 41.4 years and median injury severity score (ISS) of 13. Rate of ISS >15 was 42%. Principal mechanisms of injury were road traffic (40.4%) and falls (34.4%), with 91.5% blunt trauma. Principal patterns were brain (64.4%), chest (59.8%) and extremity/pelvic girdle (52.9%) injuries. Severe (abbreviated injury scale [AIS] score ≥ 3) orthopaedic injuries, defined as extremity and spine injuries together, accounted for 67.1%. Overall, 29.1% underwent immediate intervention, mainly by orthopaedics (27.3%), neurosurgeons (26.3 %) and visceral surgeons (13.9%); 43.8% underwent a surgical intervention within the first 24 hours and 59.1% during their hospitalisation. In-hospital mortality for patients with ISS >15 was 26.2%. CONCLUSION: This is the first 5-year report on trauma in Switzerland. Trauma workload was similar to other European countries. Despite high levels of healthcare, mortality exceeds published rates by >50%. Regardless of the importance of a multidisciplinary approach, trauma remains a surgical disease and needs dedicated surgical resources.

Amélioration de l'hyperglycémie hospitalière: création d'un nouveau modèle de gouvernance [Improvement of hospital hyperglycemia: creation of a new governance model?].

The report of significant decrease of the inpatient hospital mortality and morbidity with an efficient insulin therapy has demonstrated the need of a good glycaemic control for patients hospitalised in acute care. However, one is faced with numerous difficulties in the hospital management of patients with hyperglycaemia, errors often occur when prescribing insulin, and the management skills are insufficient. Our goal is to change the medical and nursing practices to evolve towards an efficient and safe management of the hospitalised patient. The model we lay out in this article is based upon observation of the therapeutic support of patients with a chronic condition, whilst using a systemic management approach.

Epidemiology of foodborne Norovirus outbreaks in Catalonia, Spain

Background: Noroviruses are one of the principal biological agents associated with the consumption of contaminated food. The objective of this study was to analyse the size and epidemiological characteristics of foodborne outbreaks of gastroenteritis in Catalonia, a region in the northeast of Spain.Methods: In all reported outbreaks of gastroenteritis associated with food consumption, faecal samples of persons affected were analysed for bacteria and viruses and selectively for parasites. Study variables included the setting, the number of people exposed, age, sex, clinical signs and hospital admissions. The study was carried out from October 2004 to October 2005.Results: Of the 181 outbreaks reported during the study period, 72 were caused by Salmonella and 30 by norovirus (NoV); the incidence rates were 14.5 and 9.9 per 100,000 person-years, respectively. In 50% of the NoV outbreaks and 27% of the bacterial outbreaks (p = 0.03) the number of persons affected was ¿10; 66.7% of NoV outbreaks occurred in restaurants; no differences in the attack rates were observed according to the etiology. Hospitalizations were more common (p = 0.03) in bacterial outbreaks (8.6%) than in NoV outbreaks (0.15%). Secondary cases accounted for 4% of cases in NoV outbreaks compared with 0.3% of cases in bacterial outbreaks (p < 0.001)Conclusion: Norovirus outbreaks were larger but less frequent than bacterial outbreaks, suggesting that underreporting is greater for NoV outbreaks. Food handlers should receive training on the transmission of infections in diverse situations. Very strict control measures on handwashing and environmental disinfection should be adopted in closed or partially-closed institutions.
