Considering "the more" of patients suffering from alcohol use disorders. An illustration of acute nursing care from a lifeworld-led perspective.

PURPOSE: The purpose of this study is to illustrate a theoretical value framework for humanisation of healthcare, a lifeworld-led care that has the potential to support nurses in acute medical units in addressing and meeting both challenges and care needs expressed by patients suffering from alcohol use disorders. Providing care to these patients means working with a very divergent and complex group of patients. When hospitalised in an acute medical unit, nurses are often these patients' first encounter, which gives a unique opportunity to initiate and establish a successful care alliance. METHOD:  The present study is a qualitative study based on an amplified secondary analysis of 25 pre-conducted interviews. Following a hermeneutic approach, the analysis was structured in accordance with the conceptual value framework for humanisation of care, drawing on the recognition of the patients' lifeworld as an aspect of importance. FINDINGS: The study showed that while there were examples of humanising care guided by the patients' lifeworld present, there were also situations of care that were dehumanising. Conclusion: When letting the patients' perspective of well-being be the centre of care, the patients' experience of meaningfulness and sincerity within the provided care was nurtured, and they felt more humanly met.

Clinical impact of a comprehensive nurse-led discharge intervention on patients being discharged home from an acute medical unit: Randomised controlled trial.

BACKGROUND: Acute medical units have increasingly been implemented in modern healthcare to ensure a fast track for treatment and care, thus increasing the number of patients being discharged. To avoid early readmissions, new approaches to discharging patients from these settings are needed. OBJECTIVE: To investigate the clinical impact of a comprehensive nurse-led discharge intervention on patients being discharged home from an acute medical unit. OUTCOMES: The primary outcome was 30-days hospital readmission. Secondary outcomes were utilisation of healthcare, including contacting emergency departments, the general practitioner or after-hours physicians; patient experience; and health-related quality of life. DESIGN: This study was a non-blinded randomised clinical controlled trial with a 1 year enrolment period from November 2014 to 2015. Group assignment was performed by computer generated codes. SETTING: The setting was a 34-bed acute medical unit at a Danish University Hospital. PARTICIPANTS: Non-surgical patients aged 18+ with more than one contact to hospitals during the last 12 months were eligible for inclusion. Furthermore, patients had to have been discharged home and had a follow-up appointment after discharge. METHODS: The intervention consisted of (1) an assessment of the patient's overall situation, (2) an assessment of their comprehension of discharge recommendations, (3) a simple discharge letter targeting the individual patient's health literacy and (4) a follow-up telephone call 2 days post-discharge. The study was carried out by a research nurse and the 1st author. Data was collected from medical records, registers and questionnaires. Intention-to-treat and per protocol analysis were performed. RESULTS: In all, 200 participants were enrolled (101 intervention; 99 control). Of these, 17 were excluded due to transfer to another hospital department and 4 did not receive the full intervention, resulting in 86 in the intervention group and 93 in the control group. At 30 days post-discharge, 22/101 (22%) in the intervention group had at least one readmission vs. 19/99 (19%) in the control group. The total number of all-cause readmissions in the follow-up period was 0.28 (SD: 0.67) in the intervention group vs. 0.26 (SD: 0.63) in the control group. There were no statistically significant differences in baseline characteristics or any of the primary and secondary outcomes. CONCLUSION: A comprehensive nurse-led discharge model focusing on the individual patient's situation and needs was not capable of reducing readmissions and healthcare utilisation. No statistically significant effects on quality of life or patients' experiences of the discharge from the acute medical unit were observed.

Separate norovirus outbreaks linked to one source of imported frozen raspberries by molecular analysis, Denmark, 2010-2011.

Norovirus outbreaks occur frequently in Denmark and it can be difficult to establish whether apparently independent outbreaks have the same origin. Here we report on six outbreaks linked to frozen raspberries, investigated separately over a period of 3 months. Norovirus from stools were sequence-typed; including extended sequencing of 1138 bp encompassing the hypervariable P2 region of the capsid gene. Norovirus was detected in 27 stool samples. Genotyping showed genotype GI.Pb_GI.6 (polymerase/capsid) with 100% identical sequences. Samples from five outbreaks were furthermore identical over the variable capsid P2 region. In one outbreak at a hospital canteen, frozen raspberries was associated with illness by cohort investigation (relative risk 6·1, 95% confidence interval 3·2-11). Bags of raspberries suspected to be the source were positive for genogroup I and II noroviruses, one typable virus was genotype GI.6 (capsid). These molecular investigations showed that the apparently independent outbreaks were the result of one contamination event of frozen raspberries. The contaminated raspberries originated from a single producer in Serbia and were originally not considered to belong to the same batch. The outbreaks led to consultations and mutual visits between producers, investigators and authorities. Further, Danish legislation was changed to make heat-treatment of frozen raspberries compulsory in professional catering establishments.

How should medication errors be defined? Development and test of a definition.

AIMS: Definitions of medication errors vary widely in the literature, and prevalence from 2-75% in part because of this lack of consensus. Thus, clarification of the concept is urgently needed. The objective was to develop a clear-cut definition of medication errors and specify relevant error types in the medication process. METHODS: Based on existing taxonomy and through a modified Delphi-process consensus of definition and error types were reached among Danish experts appointed by 13 healthcare organisations and the project group. The experts prioritised five definitions of medication errors and score the relevance of 76 error types. Based on explicit criteria, the project group settled non-consensus cases. RESULTS: The panel consisted of 12 physicians, seven pharmacists, and six nurses. Consensus was reached for the definition "An error in the stages of the medication process - ordering, dispensing, administering and monitoring the effect - causing harm or implying a risk of harming the patient". Moreover, consensus for 60 of 76 error types was achieved. Applied to a historic dataset the definition reduced the number of medication errors from 34% to 7%. CONCLUSIONS: Experts deemed a definition using harm or risk of harm as cut-off point as the most appropriate in Danish hospital settings. In addition, they agreed on a list of 60 error types covering the medication process. Interestingly, a substantial lower occurrence of medication errors was found when applied to historic data. The definition is in accordance with international taxonomy, thus is assumed to be applicable to modern healthcare settings abroad.

Outbreak of listeriosis caused by infected beef meat from a meals-on-wheels delivery in Denmark 2009.

An outbreak of listeriosis in Denmark occurred in May 2009. Multilocus variable number of tandem repeats analysis typing, later confirmed by pulsed-field gel electrophoresis typing, showed that isolates from eight patients had identical patterns and were distinguishable from Listeria monocytogenes isolates from other Danish patients. Seven out of eight patients had received a meal with beef from the same meals-on-wheels delivery catering company 3 weeks prior to onset of disease. Two patients died of their infection. Large-scale delivery of precooked meals to a vulnerable population represents a threat if proper measures against listeriosis are not taken.

How are medication errors defined? A systematic literature review of definitions and characteristics.

OBJECTIVE: Multiplicity in terminology has been suggested as a possible explanation for the variation in the prevalence of medication errors. So far, few empirical studies have challenged this assertion. The objective of this review was, therefore, to describe the extent and characteristics of medication error definitions in hospitals and to consider the consequences for measuring the prevalence of medication errors. DATA SOURCES AND STUDY SELECTION: and data extraction Studies were searched for in PubMed, PsychINFO, Embase and CINAHL employing primary search terms such as 'medication errors' and 'adverse drug events'. Peer-reviewed articles containing these terms as primary end-points were included. Study country, year, aim, design, data-collection methods, sample-size, interventions and MAIN RESULT: were extracted. Result of data synthesis Forty-five of 203 relevant studies provided a generic definition of medication errors including 26 different forms of wordings. The studies conducted in nine countries represented a variety of clinical settings and the approach was mainly descriptive. Of utmost importance is the documented prevalence of medication errors, which ranged from 2 to 75% with no associations found between definitions and prevalence. CONCLUSION: Inconsistency in defining medication errors has been confirmed. It appears that definitions and methods of detection rather than being reproducible and reliable methods are subject to the individual researcher's preferences. Thus, application of a clear-cut definition, standardized terminology and reliable methods has the potential to greatly improve the quality and consistency of medication error reporting. Efforts to achieve a common accepted definition that defines the scope and content are therefore needed.

Norovirus outbreaks linked to oyster consumption in the United Kingdom, Norway, France, Sweden and Denmark, 2010.

This paper reports on several simultaneous outbreaks of norovirus infection linked to the consumption of raw oysters. Since January 2010, 334 cases in 65 clusters were reported from five European countries: the United Kingdom, Norway, France, Sweden and Denmark. The article describes the available epidemiological and microbiological evidence of these outbreaks.

Outbreaks of gastroenteritis linked to lettuce, Denmark, January 2010.

At least 11 linked outbreaks of gastroenteritis with a total of 260 cases have occurred in Denmark in mid January 2010. Investigations showed that the outbreaks were caused by norovirus of several genotypes and by enterotoxigenic Escherichia coli. Lettuce of the lollo bionda type grown in France was found to be the vehicle.

A foodborne outbreak of Cryptosporidium hominis infection.

Foodborne outbreaks of cryptosporidiosis are uncommon. In Denmark human cases are generally infrequently diagnosed. In 2005 an outbreak of diarrhoea affected company employees near Copenhagen. In all 99 employees were reported ill; 13 were positive for Cryptosporidium hominis infection. Two analytical epidemiological studies were performed; an initial case-control study followed by a cohort study using an electronic questionnaire. Disease was associated with eating from the canteen salad bar on one, possibly two, specific weekdays [relative risk 4.1, 95% confidence interval (CI) 2.1-8.3]. Three separate salad bar ingredients were found to be likely sources: peeled whole carrots served in a bowl of water, grated carrots, and red peppers (in multivariate analysis, whole carrots: OR 2.1, 95% CI 1.1-4.0; grated carrots: OR 2.1, 95% CI 1.2-3.9; peppers: OR 3.3, 95% CI 1.7-6.6). We speculate that a person excreting the parasite may have contaminated the salad buffet.

Outbreaks of Shigella sonnei infections in Denmark and Australia linked to consumption of imported raw baby corn.

We investigated an outbreak of Shigella sonnei infections in Denmark and Australia associated with imported baby corn from one packing shed in Thailand. We reviewed nationwide surveillance and undertook case finding, food trace-back and microbiological investigation of human, food and environmental samples. A recall of baby corn and sugar snaps was based on descriptive epidemiological evidence. In Denmark, we undertook a retrospective cohort study in one workplace. In total, 215 cases were laboratory-confirmed in Denmark, and 12 in Australia. In a multivariable analysis, baby corn was the only independent risk factor. Antibiotic resistance and PFGE outbreak profiles in Denmark and Australia were indistinguishable, linking the outbreaks. Although we did not detect S. sonnei in baby corn, we isolated high levels of other enteric pathogens. We identified a packing shed in Thailand that supplied baby corn to Denmark and Australia, and uncovered unhygienic practices in the supply chain. This outbreak highlights the importance of international communication in linking outbreaks and pinpointing the source.

A foodborne outbreak of enterotoxigenic E. coli and Salmonella Anatum infection after a high-school dinner in Denmark, November 2006.

In industrialized countries enterotoxigenic Escherichia coli (ETEC) is mainly diagnosed as a cause of travellers' diarrhoea, but it is also known to cause foodborne outbreaks. We report an outbreak of acute gastroenteritis caused by ETEC serotypes O92:H- and O153:H2 as well as Salmonella Anatum, which affected around 200 students and teachers after a high-school dinner in Greater Copenhagen, Denmark, November 2006. A retrospective cohort study showed that consumption of pasta salad with pesto was associated with an increased risk of illness (attack rate 59.4%; risk ratio 2.6, 95% confidence interval 1.2-5.7). Imported fresh basil used for preparation of the pesto was the most likely source of contamination. Although ETEC is associated with travellers' diarrhoea in Denmark, this outbreak suggests that a proportion of sporadic ETEC infections might be caused by contaminated imported foodstuffs. To improve food safety further, it is important to target this poorly regulated and researched area.

Denmark: botulism in an infant or infant botulism?

A 4.5 months old, previously healthy Danish girl was admitted to a paediatric department after six days of passive behaviour and weak suck. Over the next days she became increasingly weak, developed bilateral ptosis, the muscle stretch reflexes were lost, and mydriasis with slow pupillary responses was noted. Botulism was suspected and confirmed by testing of patient serum in a bioassay. The condition of the patient improved following administration of botulism antiserum. The clinical picture was suggestive of intestinal (infant) botulism. However, botulism acquired from consumption of food with preformed neurotoxin could not be excluded.

Large outbreaks of Salmonella Typhimurium infection in Denmark in 2008.

An outbreak of Salmonella Typhimurium phage type U292 has been ongoing in Denmark since 1 April, with 1,054 cases registered until 23 October 2008. Extensive investigations including hypothesis-generating interviews, matched case-control studies, cohort studies in embedded outbreaks, shopping list analyses, analyses of food samples from patient's homes, trace-back analyses and extensive microbiological analysis of products have not provided clear indications of a specific source of infection but the main hypothesis is that the vehicle of the outbreak are different pork products. In addition to the large U292 outbreak, at least four other S. Typhimurium outbreaks (caused by phage types U288, DT120, DT3 and DT135) have been investigated in Denmark in 2008.

Outbreak of group A streptococcal throat infection: don't forget to ask about food.

We report a large foodborne outbreak due to group A streptococci (GAS), which caused acute tonsillo-pharyngitis in 200-250 patrons of a company canteen in Copenhagen, Denmark, in June 2006. A retrospective cohort study of canteen users showed that consumption of cold pasta was associated with an increased risk of illness (attack rate 68%, risk ratio 4.1, P<0.0001). Indistinguishable GAS strains (emm89, T-type 3/13/B3264) were cultured from three cases and a cook, who had prepared the pasta. To our knowledge, pasta has previously only twice been incriminated as the source of a GAS outbreak. Only six foodborne GAS outbreaks have been reported in Europe since 1970, four of them in Sweden or Denmark. This geographical clustering suggests that foodborne GAS outbreaks are probably under-recognized elsewhere.

Outbreaks of shigellosis in Denmark and Australia associated with imported baby corn, August 2007--final summary.

The recently reported concurrent outbreaks of Shigella sonnei infections in Denmark and Australia have been found to be linked to a common baby corn packing house in Thailand via trace-back of the distribution chain. Distribution records indicated that three additional countries received affected product from the implicated Thai packing house during the period of potential contamination. These countries were notified through the World Health Organization's International Food Safety Authorities Network (INFOSAN). Associated cases of S. sonnei have not been reported in these three countries.

An outbreak of Campylobacter jejuni associated with consumption of chicken, Copenhagen, 2005.

In May/June 2005 an outbreak of diarrhoeal illness occurred among company employees in Copenhagen. Cases were reported from seven of eight companies that received food from the same catering kitchen. Stool specimens from three patients from two companies were positive for Campylobacter jejuni. We performed a retrospective cohort study among employees exposed to canteen food in the three largest companies to identify the source of the outbreak and to prevent further spread. Using self-administered questionnaires we collected information on disease, days of canteen food eaten and food items consumed. The catering kitchen was inspected and food samples were taken. Questionnaires were returned by 295/348 (85%) employees. Of 247 employees who ate canteen food, 79 were cases, and the attack rate (AR) was 32%. Consuming canteen food on 25 May was associated with illness (AR 75/204, RR=3.2, 95%CI 1.3-8.2). Consumption of chicken salad on this day, but not other types of food, was associated with illness (AR=43/97, RR=2.3, 95%CI 1.3-4.1). Interviews with kitchen staff indicated the likelihood of cross-contamination from raw chicken to the chicken salad during storage. This is the first recognised major Campylobacter outbreak associated with contaminated chicken documented in Denmark. It is plausible that food handling practices contributed to transmission, and awareness of safe food handling and storage has since been raised among kitchen staff. The low number of positive specimens accrued in this outbreak suggests a general underascertainment of adult cases in the laboratory reporting system by a factor of 20.
