Burdens, resources, health and wellbeing of nurses working in general and specialised palliative care in Germany - results of a nationwide cross-sectional survey study.

BACKGROUND: Palliative care in Germany is divided into general (GPC) and specialised palliative care (SPC). Although palliative care will become more important in the care sector in future, there is a large knowledge gab, especially with regard to GPC. The aim of this study was to identify and compare the burdens, resources, health and wellbeing of nurses working in GPC and SPC. Such information will be helpful for developing prevention programs in order to reduce burdens and to strengthen resources of nurses. METHODS: In 2017, a nationwide cross-sectional survey was conducted. In total, 437 nurses in GPC and 1316 nurses in SPC completed a questionnaire containing parts of standardised instruments, which included parts of the Copenhagen Psychosocial Questionnaire (COPSOQ), the Patient Health Questionnaire (PHQ-2), the Resilience Scale (RS-13) Questionnaire, a single question about back pain from the health survey conducted by the Robert Koch Institute as well as self-developed questions. The differences in the variables between GPC and SPC nurses were compared. RESULTS: SPC nurses reported higher emotional demands as well as higher burdens due to nursing care and the care of relatives while GPC nurses stated higher quantitative demands, i.e. higher workload. SPC nurses more often reported organisational and social resources that were helpful in dealing with the demands of their work. Regarding health, GPC nurses stated a poorer health status and reported chronic back pain as well as a major depressive disorder more frequently than SPC nurses. Furthermore, GPC nurses reported a higher intention to leave the profession compared to SPC nurses. CONCLUSIONS: The findings of the present study indicate that SPC could be reviewed as the best practice example for nursing care in Germany. The results may be used for developing target group specific prevention programs for improving health and wellbeing of nurses taking the differences between GPC and SPC into account. Finally, interventional and longitudinal studies should be conducted in future to determine causality in the relationship of burdens, resources, health and wellbeing.

Arbeitsbedingungen von Pflegekräften in der allgemeinen Palliativversorgung in Deutschland.

Working conditions of nurses in general palliative care in Germany - A cross-sectional survey Abstract. Background: Most terminally ill people are treated within general palliative care including outpatient care, nursing homes and hospitals. In contrast, only a small number is treated within specialised palliative care. Nursing research within the framework of palliative care focuses on the latter. AIM: To investigate the working conditions of nurses working in general palliative care and to analyse potential differences between nurses in outpatient care, in nursing homes and in hospitals. METHODS: A cross-sectional survey was conducted among nurses working in outpatient care, in nursing homes and in hospitals. The questionnaire included questions about working conditions, parts of the Copenhagen Psychosocial Questionnaire and self-developed questions. Descriptive and bivariate analyses were conducted. RESULTS: 437 questionnaires entered final analyses (response rate 16.7 %). On average, nurses spend 20 % of their working time with palliative care. Every fourth nurse (n = 104) express the wish for an additional qualification in palliative care. The following demands are reported: confrontation with pain, death and dying, as well as care of relatives. 59 % (n = 249) of the nurses evaluate the quality of palliative care as good / very good. CONCLUSIONS: Nurses are faced with demands, which so far had only been a subject of discussion within the framework of the specialised palliative care. Further steps for action, in particular the additional qualification in palliative care for nurses, should be discussed.

Health and intention to leave the profession of nursing - which individual, social and organisational resources buffer the impact of quantitative demands? A cross-sectional study.

BACKGROUND: The aim of this study was to analyse the buffering effect of individual, social and organisational resources on health and intention to leave the profession in the context of burden due to quantitative job demands. METHODS: In 2017, a cross-sectional survey was carried out anonymously among nurses in palliative care in Germany. One thousand three hundred sixteen nurses responded to the questionnaire (response rate 38.7%), which contained, amongst others, questions from the German version of the Copenhagen Psychosocial Questionnaire (COPSOQ). Moderator analyses were conducted to investigate the buffering effect of different resources on health ('self-rated health' and 'burnout') and 'intention to leave' in the context of quantitative demands. RESULTS: 'Self-rated health' was significantly buffered by the resources 'recognition through salary' (p = 0.001) and 'good working team' (p = 0.004). Additionally, buffering effects of the resources 'workplace commitment' and 'good working team' on 'burnout' (p = 0.001 and p = 0.006, respectively) as well as of the resources 'degree of freedom', 'meeting relatives after death of patients', 'recognition from supervisor' and 'possibilities for development' on 'intention to leave' (p = 0.014, p = 0.012, p = 0.007 and p = 0.036, respectively) were observed. CONCLUSIONS: The results of our study can be used to develop and implement job (re) design interventions with the goal of reducing the risk of burnout and enhancing job satisfaction among nurses in palliative care. This includes for example adequate payment, communication training and team activities or team events to strengthen the team as well as the implementation of some rituals (such as meeting relatives after the death of patients). As our study was exploratory, the results should be confirmed in further studies.

[Violence and discrimination in the workplace. The effects on health and setting-related approaches to prevention and rehabilitation]. / Gewalt und Diskriminierung am Arbeitsplatz. Gesundheitliche Folgen und settingbezogene Ansätze zur Prävention und Rehabilitation.

Violence in the workplace is a widespread problem that manifests itself in very different forms. The consequences for victims and companies are equally diverse. Sexual harassment is a special form of violence at the workplace. Violence may come from external perpetrators (attacks on cashiers) or from persons inside a company or establishment (colleagues, patients, people in care). Statutory accident insurance institutions in Germany (UV, "Unfallversicherungsträger") receive approximately 16,000 occupational injury reports per year that resulted from violence and led to extended incapacity to work. The numbers are increasing steadily. Particularly affected by violence are people working in healthcare and social welfare. Both psychological and physical violence can lead to severe disorders such as post-traumatic stress disorder (PTSD). To avoid violence, technical, organisational, and personal protective measures are needed. The training of de-escalation officers in the areas affected can be helpful. For victims of psychological and physical violence in the workplace, the UV offers special psychotherapeutic support and recommends the training of first-aiders.

MRSA carriage among healthcare workers in non-outbreak settings in Europe and the United States: a systematic review.

ABSTARCT BACKGROUND: A recent review estimated prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in healthcare workers (HCWs) to be 4.6%. However, MRSA carriage in HCWs in non-outbreak settings is thought to be higher than in an outbreak situation, due to increased hygiene awareness in outbreaks, but valid data are missing. The goals of this paper are to summarise the prevalence of MRSA carriage amongst HCWs in non-outbreak situations and to identify occupational groups in healthcare services associated with a higher risk of MRSA colonisation. METHODS: A systematic search for literature was conducted in the MEDLINE and EMBASE databases. The methodological quality of the studies was assessed using seven criteria. Pooled prevalence rates were calculated. Pooled effect estimates were identified in a meta-analysis. RESULTS: 31 studies were included in this review. The pooled MRSA colonisation rate was 1.8% (95% confidence interval [CI], 1.34%-2.50%). The rate increased to 4.4% (95% CI, 3.98%-4.88%) when one study from the Netherlands was excluded. The pooled MRSA rate was highest in nursing staff (6.9%). Nursing staff had an odds ratio of 1.72 (95% CI, 1.07-2.77) when compared with medical staff and an odds ratio of 2.58 (95%, 1.83-3.66) when compared with other healthcare staff. Seven studies were assessed as being of high quality. The pooled MRSA prevalence in high quality studies was 1.1% or 5.4% if the one large study from the Netherlands is not considered. The pooled prevalence in studies of moderate quality was 4.0%. CONCLUSIONS: MRSA prevalence among HCWs in non-outbreak settings was no higher than carriage rates estimated for outbreaks. Our estimate is in the lower half of the range of the published MRSA rates in the endemic setting. Our findings demonstrate that nursing staff have an increased risk for MRSA colonisation. In order to confirm this finding, more studies are needed, including healthcare professionals with varying degrees of exposure to MRSA. In order to reduce misclassification bias, standardisation of HCWs screening is warranted.

Musculoskeletal pain and effort-reward imbalance--a systematic review.

BACKGROUND: Musculoskeletal pain may be triggered by physical strains and psychosocial risk factors. The effort-reward imbalance model (ERI model) is a stress model which measures psychosocial factors in the working world. The question is whether workers with an effort-reward imbalance report musculoskeletal pain more frequently than those with no effort-reward imbalance. A systematic review using a best evidence synthesis approach was conducted to answer this question. METHODS: A literature search was conducted for the period from 1996 to 2012, using three databases (Pubmed, Embase and PsycINFO). The research criteria related to psychosocial, work-related stress as per the ERI model and to musculoskeletal pain. A quality score was developed using various quality criteria to assess the standard of the studies. The level of evidence was graded as in (Am J Ind Med 39:180-193, 2001). RESULTS: After applying the inclusion criteria, a total of 19 studies were included in the review: 15 cross-sectional studies, three prospective studies and one case-control study. 74% of all studies exhibited good methodological quality, 53% collected data using the original ERI questionnaire, and in 42% of the studies, there was adequate control for physical working conditions. Furthermore, different cut-off points were used to classify exposed and non-exposed individuals. On the basis of 13 studies with a positive, statistically significant association, a moderate level of evidence was inferred for the association between effort-reward imbalance and musculoskeletal pain. The evidence for a role of over-commitment and for its interaction with effort-reward imbalance was rated as inconclusive - on the basis of eight and five studies, respectively. CONCLUSIONS: On the basis of the available evidence, no reliable conclusion may be drawn about any association between the psychosocial factors ascertained using the ERI model and musculoskeletal pain. Before a reliable statement can be made on the association between ERI and musculoskeletal pain, additional longitudinal studies must be performed - with a standardised method for recording and classifying exposure, as well as control of physical confounders. Appropriate preventive measures can then be specified.

[Emergency care as a high-risk workplace-Measures to deal with violence against employees]. / Notfallversorgung als risikoreicher Arbeitsplatz ­ Maßnahmen zum Umgang mit Gewalt gegen Beschäftigte.

BACKGROUND: Many employees in the field of emergency care experience verbal and physical violence caused by patients or visitors. The aim of this project is to gain insights into which measures are available to deal with violence in emergency care and how employees subjectively evaluate them. METHODS: A nationwide cross-sectional online survey was conducted in 2020. The questionnaire contained items on violence prevention, intervention, and follow-up measures. Quantitative data were analysed descriptively and free text data according to Mayring's qualitative content analysis. RESULTS: A total of 349 respondents, including 115 supervisors participated in the survey. The availability of security staff and standardised reporting of incidents were considered important measures for dealing with violence. Of the managers, 67% reported not having a security service, while 56% claimed that reported incidents of violence were not dealt with in a structured way. A high workload in emergency care can impede the implementation of measures. Overall, the demand for increased support by supervisors and the hospital management became clear. CONCLUSION: It is evident that employees consider certain measures to be effective; however, these measures are often not consistently implemented. There is a need for structured reporting of violent incidents against employees to facilitate a realistic recording of the prevalence. In addition to increasing the (nursing) staff, restricting access for visitors can decrease the conflict potential.

Longitudinal SARS-CoV-2 Seroprevalence among Employees in Outpatient Care Services in Hamburg.

The risk of SARS-CoV-2 infection is particularly high for healthcare workers during the pandemic. Home care workers visit many different households per shift. Encounters with mostly elderly patients and their relatives increase the potential for the undetected spread of SARS-CoV-2. In order to gain insight into the seroprevalence of SARS-CoV-2 antibodies and possible transmission risks in outpatient care, this follow-up study was conducted with nursing services in Hamburg. The aim was to estimate the dynamics of seroprevalence in this occupational group over a 12-month period, to identify occupation-specific risk factors, and to collect information on the vaccination status of the surveyed nursing staff. Antibody testing for SARS-CoV-2 IgG against the S1 domain (EUROIMUN Analyser I® Lübeck, Germany) was performed on participating healthcare workers with patient contact at a total of four time points within one year from July 2020 to October 2021 (baseline, follow-up after three, six and twelve months). The data were mostly analysed descriptively. Differences in IgG titres were analysed using variance analysis methods, particularly Tukey's range test. The seroprevalence was 1.2% (8/678) at baseline and 1.5% (9/581) at the three-month follow-up (T1). At the second follow-up (T2) after six months, vaccination against SARS-CoV-2 was available from January 2021 onwards. The prevalence rate of positive IgG antibodies relative to the S1 domain of the spike protein test among unvaccinated individuals was 6.5%. At (T3) after twelve months (July to October 2021), 482 participants were enrolled, and 85.7% of the workers were considered fully vaccinated at this time point, while 51 individuals were unvaccinated. The prevalence was 13.7% (7/51). In our study, a low seroprevalence was found among home care workers, which was lower than in our studies conducted in the clinical setting. Therefore, it can be assumed that the occupational risk of infection is rather low for both the nursing staff and the patients/clients cared for in the outpatient setting. The good provision of protective equipment and the high vaccination rate of the staff probably had a positive influence.

COVID-19 infections in staff of an emergency care hospital after the first wave of the pandemic in Germany.

Background: Hospital staff have an increased risk of SARS-CoV-2 infection. It is thus necessary to monitor the situation because infected staff may in turn infect patients and their family members. Following the first wave of infection in the summer of 2020, the Rhine-Maas Hospital (RMK) provided all staff the opportunity to be tested for SARS-COV-2 via antibody testing. Methods: The tests were carried out from 19.6.2020 to 17.7.2020. The IgG antibody test qualitatively tested for SARS-CoV-2 antibodies via enzyme-linked immunosorbent assay (ELISA). An IgG titre of 0.8 IU/mL or more was considered positive. All staff who tested positive for SARS-CoV-2 by PCR testing after February 2020 were also included in the study. Occupational and non-occupational risk factors for infection were determined. Staff in the intensive care ward, the emergency depart-ment, or a SARS-CoV-2 ward ("corona ward") were predefined as having increased exposure. Odds ratios (OR) were calculated using logistical regression for occupational and private infection risk. Results: 903 staff members (58.9%) with complete data took part in the cross-sectional study. 52 staff members (5.8%) had a positive PCR test result in their medical history or tested positive in the IgG test. Around half of the infections (55%) were only detected by serological testing during the study. Staff with tasks classified as at-risk had an OR of 1.9 (95% CI 1.04-3.5) for infection. Risk factors also included private contacts to people infected with SARS-CoV-2 and holidays in risk areas. At the time of data collection, 11.5% of those with the disease reported that they had not yet fully recovered from COVID-19. Discussion: Following the first COVID-19 wave, 5.3% of staff at the RMK were infected. An increase in occupational infection risk was found even after controlling for non-occupational infection risks. This should be taken into account with regard to the recognition of COVID-19 as an occupational disease. Methods to improve protection against nosocomial transmissions should be considered.

Risk of Burnout among Emergency Department Staff as a Result of Violence and Aggression from Patients and Their Relatives.

Emergency department staff are often affected by incidents of violence. The aim of the study was to generate data on the frequency of violence by patients and accompanying relatives and the correlation between experienced aggression, a possible risk of burnout and a high sense of stress. Additionally, the buffering effect of good preventive preparation of care staff by the facility on aggressive visitors and patients was examined. In this cross-sectional study, members of the German Society for Interdisciplinary Emergency and Acute Medicine were surveyed. The investigation of risk factors, particularly experiences of verbal and physical violence, as well as exhaustion and stress, was carried out using ordinal regression models. A total of 349 staff from German emergency departments took part in the survey, 87% of whom had experienced physical violence by patients and 64% by relatives. 97% had been confronted with verbal violence by patients and 94% by relatives. Violence by relatives had a negative effect on perceived stress. High resilience or effective preparation of employees for potential attacks was shown to have a protective effect with regard to the burnout risk and perceived stress. Therefore, management staff play a major role in preventing violence and its impact on employees.

MRSA prevalence in European healthcare settings: a review.

BACKGROUND: During the past two decades, methicillin-resistant Staphylococcus aureus (MRSA) has become increasingly common as a source of nosocomial infections. Most studies of MRSA surveillance were performed during outbreaks, so that results are not applicable to settings in which MRSA is endemic. This paper gives an overview of MRSA prevalence in hospitals and other healthcare institutions in non-outbreak situations in Western Europe. METHODS: A keyword search was conducted in the Medline database (2000 through June 2010). Titles and abstracts were screened to identify studies on MRSA prevalence in patients in non-outbreak situations in European healthcare facilities. Each study was assessed using seven quality criteria (outcome definition, time unit, target population, participants, observer bias, screening procedure, swabbing sites) and categorized as 'good', 'fair', or 'poor'. RESULTS: 31 observational studies were included in the review. Four of the studies were of good quality. Surveillance screening of MRSA was performed in long-term care (11 studies) and acute care (20 studies). Prevalence rates varied over a wide range, from less than 1% to greater than 20%. Prevalence in the acute care and long-term care settings was comparable. The prevalence of MRSA was expressed in various ways - the percentage of MRSA among patients (range between 1% and 24%), the percentage of MRSA among S. aureus isolates (range between 5% and 54%), and as the prevalence density (range between 0.4 and 4 MRSA cases per 1,000 patient days). The screening policy differed with respect to time points (on admission or during hospital stay), selection criteria (all admissions or patients at high risk for MRSA) and anatomical sampling sites. CONCLUSIONS: This review underlines the methodological differences between studies of MRSA surveillance. For comparisons between different healthcare settings, surveillance methods and outcome calculations should be standardized.

The occupational risk of Helicobacter pylori infection among gastroenterologists and their assistants.

BACKGROUND: Helicobacter pylori is a widely spread bacterium that mainly inhabits the gastric mucosa and can lead to serious illnesses such as peptic ulcer disease, gastric carcinoma and gastric MALT lymphoma. The oral-oral route seems to be the main transmission route. The fact that endoscopes are contaminated after being used to perform a gastroscopy leads one to question whether gastroenterologists and endoscopy nurses and assistants run a higher risk of infection. METHODS: A systematic search for literature was conducted in the MEDLINE and EMBASE databases and further publications were found in reference lists of relevant articles. Epidemiological studies on the occupational exposure of endoscopy personnel were collected and their quality was assessed. Pooled effect estimates were identified in a meta-analysis. RESULTS: Of the 24 studies included in the analysis, 15 were considered to be methodologically good. Of these 15 studies, eight single studies showed a statistically significant increased risk of infection for gastroenterologists, and five for their assistants. Meta-analysis across all methodologically good studies found a statistically significant risk of 1.6 (95%CI 1.3-2.0) for doctors. The pooled effect estimates also indicated a statistically significant risk of Helicobacter pylori infection (RR 1.4; 95%CI 1.1-1.8) for assistants too.When studies are stratified by medical and non-medical control groups, statistically significant risks can only be recognised in the comparison with non-medical controls. CONCLUSIONS: In summary, our results demonstrated an increased risk of Helicobacter pylori infection among gastroenterological personnel. However, the choice of control group is important for making a valid assessment of occupational exposure risks.

Specificity of a whole blood IGRA in German nursing students.

BACKGROUND: Interferon-gamma release assays (IGRA) are used for tuberculosis (TB) screening in healthcare workers (HCWs). However, data on specificity of IGRA in serial testing of HCWs is sparse. Therefore the specificity and the negative predictive value of the IGRA - QuantiFERON-TB Gold In-Tube (QFT) - in German nursing students was investigated. METHODS: 194 nursing students at the start of their professional career were tested with the QFT. 14 nursing students were excluded from the specificity analysis, due to exposure to mycobacterium tuberculosis. Two of these subjects were QFT- positive. None of them developed disease during the year of follow-up. A study group of 180 students, all with very low risk of prior TB infection, remained in the specificity analysis. Subjects were monitored for at least two years with respect to the development of active TB disease. IGRA was performed at the start of the training and after one year. RESULTS: The mean age of the study group (n = 180) was 23 years (range 18-53) with 70.9% female and 99.4% German born. The specificity of QFT was 98.9% (178/180; 95% CI 0.96-0.99); lowering the cut-off from 0.35 IU/ml to 0.1 IU/ml would have decreased specificity only slightly to 97.8% (176/180; 95% CI 0.94-0.99). Of the 154 nursing students available for re-testing, one student who initially scored positive reverted to negative, and one student initially negative converted to positive. None of the monitored group with initially negative QFT results developed TB disease, indicating a high negative predictive value of the IGRA in this population. CONCLUSIONS: Following our data, QFT can serve as an effective tool in pre-employment TB screenings for HCWs. As its negative results were stable over time, specificity of the QFT in serial testing of HCWs is high. As the risk of acquiring TB infection in the German healthcare system appears to be low, our data supports the recommendation of performing TB screening only in those HCWs with known contact to TB patients or infectious materials.

Systematic review of cost and cost-effectiveness of different TB-screening strategies.

BACKGROUND: Interferon-γ release assays (IGRAs) for TB have the potential to replace the tuberculin skin test (TST) in screening for latent tuberculosis infection (LTBI). The higher per-test cost of IGRAs may be compensated for by lower post-screening costs (medical attention, chest x-rays and chemoprevention), given the higher specificity of the new tests as compared to that of the conventional TST. We conducted a systematic review of all publications that have addressed the cost or cost-effectiveness of IGRAs. The objective of this report was to undertake a structured review and critical appraisal of the methods used for the model-based cost-effectiveness analysis of TB screening programmes. METHODS: Using Medline and Embase, 75 publications that contained the terms "IGRA", "tuberculosis" and "cost" were identified. Of these, 13 were original studies on the costs or cost-effectiveness of IGRAs. RESULTS: The 13 relevant studies come from five low-to-medium TB-incidence countries. Five studies took only the costs of screening into consideration, while eight studies analysed the cost-effectiveness of different screening strategies. Screening was performed in high-risk groups: close contacts, immigrants from high-incidence countries and healthcare workers. Two studies used the T-SPOT.TB as an IGRA and the other studies used the QuantiFERON-TB Gold and/or Gold In-Tube test. All 13 studies observed a decrease in costs when the IGRAs were used. Six studies compared the use of an IGRA as a test to confirm a positive TST (TST/IGRA strategy) to the use of an IGRA-only strategy. In four of these studies, the two-step strategy and in two the IGRA-only strategy was more cost-effective. Assumptions about TST specificity and progression risk after a positive test had the greatest influence on determining which IGRA strategy was more cost-effective. CONCLUSION: The available studies on cost-effectiveness provide strong evidence in support of the use of IGRAs in screening risk groups such as HCWs, immigrants from high-incidence countries and close contacts. So far, only two studies provide evidence that the IGRA-only screening strategy is more cost-effective.

Interventions for Workplace Violence Prevention in Emergency Departments: A Systematic Review.

Emergency departments (EDs) are high-risk settings for workplace violence, but interventions to prevent violent incidents and to prepare staff are not yet consistently implemented, and their effectiveness is often unclear. This study aims to summarise evidence on workplace violence prevention interventions that were implemented in EDs to reduce violent incidents caused by patients/relatives or to increase the knowledge, skills or feelings of safety of ED staff. A systematic review was conducted. The databases MEDLINE, Web of Science, Cochrane Library, CINAHL and PsycINFO were searched for studies dated between January 2010 and May 2021. Interventional and observational studies reporting on behavioural, organisational or environmental interventions among healthcare workers in hospital EDs were included. Studies were assessed for methodological quality using the Johanna Briggs Institute Tools. Key findings of studies were summarised narratively. Fifteen studies were included, of which eleven examined behavioural interventions (classroom, online or hybrid training programmes) on de-escalation skills, violent person management or self-defence techniques. Four studies included in addition, organisational and environmental interventions. Most studies showed that interventions had a positive effect in the form of a reduction of violent incidents or an improvement in how prepared staff were to deal with violent situations; however, evidence is still sparse. Further studies should consider in particular, environmental and organisational interventions and ensure a high methodological quality.

Sexual Harassment by Patients, Clients, and Residents: Investigating Its Prevalence, Frequency and Associations with Impaired Well-Being among Social and Healthcare Workers in Germany.

Social and healthcare workers are at high risk of experiencing sexual harassment in the workplace. Although sexual harassment is detrimental to people's well-being, only a few studies have systematically investigated social and healthcare workers' experiences of different forms of sexually harassing behaviors by patients, clients, and residents in Germany. This study aimed to address this gap by determining the prevalence rates and frequency of nonverbal, verbal, and physical sexual harassment by patients, clients, and residents against social and healthcare workers. In addition, we examined the associations of sexual harassment with workers' well-being and described employees' awareness of offers of organizational support for sexual harassment prevention and aftercare. Data were collected from n = 901 employees working in a total of 61 facilities, including inpatient and outpatient care, psychiatric facilities, hospitals, and facilities for persons with disabilities. While the prevalence, frequency, and predominant forms of sexual harassment differed across sectors, the results indicated that nonverbal, verbal and physical sexual harassment were highly prevalent in social and healthcare work, with both men and women being affected. Furthermore, we found that sexual harassment was positively related to impaired well-being (e.g., depressiveness and psychosomatic complaints). In terms of support offers for sexual harassment prevention and aftercare, we found that approximately one-third of social and healthcare workers were not aware of any offers at their facilities. In addition to highlighting the problem of sexual harassment by patients, clients, and residents in social and healthcare settings, this study provides recommendations for the development of interventions and suggests several avenues for future research.

The relationship between workload and burnout among nurses: The buffering role of personal, social and organisational resources.

Workload in the nursing profession is high, which is associated with poor health. Thus, it is important to get a proper understanding of the working situation and to analyse factors which might be able to mitigate the negative effects of such a high workload. In Germany, many people with serious or life-threatening illnesses are treated in non-specialized palliative care settings such as nursing homes, hospitals and outpatient care. The purpose of the present study was to investigate the buffering role of resources on the relationship between workload and burnout among nurses. A nationwide cross-sectional survey was applied. The questionnaire included parts of the Copenhagen Psychosocial Questionnaire (COPSOQ) (scale 'quantitative demands' measuring workload, scale 'burnout', various scales to resources), the resilience questionnaire RS-13 and single self-developed questions. Bivariate and moderator analyses were performed. Palliative care aspects, such as the 'extent of palliative care', were incorporated to the analyses as covariates. 497 nurses participated. Nurses who reported 'workplace commitment', a 'good working team' and 'recognition from supervisor' conveyed a weaker association between 'quantitative demands' and 'burnout' than those who did not. On average, nurses spend 20% of their working time with palliative care. Spending more time than this was associated with 'burnout'. The results of our study imply a buffering role of different resources on burnout. Additionally, the study reveals that the 'extent of palliative care' may have an impact on nurse burnout, and should be considered in future studies.

Risk of latent TB infection in individuals employed in the healthcare sector in Germany: a multicentre prevalence study.

BACKGROUND: Healthcare workers are still recognised as a high-risk group for latent TB infection (LTBI). Therefore, the screening of people employed in the healthcare sector for active and LTBI is fundamental to infection control programmes in German hospitals. It was the aim of the study to determine the prevalence and putative risk factors of LTBI. METHODS: We tested 2028 employees in the healthcare sector with the QuantiFERON-Gold In-tube (QFT-IT) test between December 2005 and May 2009, either in the course of contact tracing or in serial testing of TB high-risk groups following German OSH legislation. RESULTS: A positive IGRA was found in 9.9% of the healthcare workers (HCWs). Nurses and physicians showed similar prevalence rates (9.7% to 9.6%). Analysed by occupational group, the highest prevalence was found in administration staff and ancillary nursing staff (17.4% and 16.7%). None of the individuals in the trainee group showed a positive IGRA result. In the different workplaces the observed prevalence was 14.7% in administration, 12.0% in geriatric care, 14.2% in technicians (radiology, laboratory and pathology), 6.5% in admission ward staff and 8.3% in the staff of pulmonary/infectious disease wards. Putative risk factors for LTBI were age (>55 years: OR14.7, 95% CI 5.1-42.1), being foreign-born (OR 1.99, 95% CI 1.4-2.8), TB in the individual's own history (OR 4.96, 95% CI 1.99-12.3) and previous positive TST results (OR 3.5, 95% CI 2.4-4.98). We observed no statistically significant association with gender, BCG vaccination, workplace or profession. CONCLUSION: The prevalence of LTBI in low-incidence countries depends on age. We found no positive IGRA results among trainees in the healthcare sector. Incidence studies are needed to assess the infection risk. Pre-employment screening might be helpful in this endeavour.

Predictors of persistently positive Mycobacterium-tuberculosis-specific interferon-gamma responses in the serial testing of health care workers.

BACKGROUND: Data on the performance of Mycobacterium-tuberculosis-specific interferon-(IFN)-gamma release assays (IGRAs) in the serial testing of health care workers (HCWs) is limited. The objective of the present study was to determine the frequency of IGRA conversions and reversions and to identify predictors of persistent IGRA positivity among serially tested German HCWs in the absence of recent extensive tuberculosis (TB) exposure. METHODS: In this observational cohort-study HCWs were prospectively recruited within occupational safety and health measures and underwent a tuberculin skin test (TST) and the IGRA QuantiFERON-TB Gold In-Tube (QFT-GIT) at baseline. The QFT-GIT was repeated 18 weeks later in the median. QFT-GIT conversions (and reversions) were defined as baseline IFN-gamma < 0.35 IU/ml and follow-up IFN-gamma > or = 0.35 IU/ml (and vice versa). Predictors of persistently positive QFT-GIT results were calculated by logistic regression analysis. RESULTS: In total, 18 (9.9%) and 15 (8.2%) of 182 analyzed HCWs were QFT-GIT-positive at baseline and at follow-up, respectively. We observed a strong overall agreement between baseline and follow-up QFT-GIT results (kappa = 0.70). Reversions (6/18, 33.3%) occurred more frequently than conversions (3/162, 1.9%). Age and positive prior and recent TST results independently predicted persistent QFT-GIT positivity. Furthermore, the chance of having persistently positive QFT-GIT results raised about 3% with each additional 0.1 IU/ml increase in the baseline IFN-gamma response (adjusted odds ratio 1.03, 95% confidence interval 1.01-1.04). No active TB cases were detected within an observational period of more than two years. CONCLUSIONS: The QFT-GIT's utility for the application in serial testing was limited by a substantial proportion of reversions. This shortcoming could be overcome by the implementation of a borderline zone for the interpretation of QFT-GIT results. However, further studies are needed to clearly define the within-subject variability of the QFT-GIT and to confirm that increasing age, concordantly positive TST results, and the extend of baseline IFN-gamma responses may predict the persistence of QFT-GIT positivity over time in serially tested HCWs with only a low or medium TB screening risk in a TB low-incidence setting.

Bladder cancer among hairdressers: a meta-analysis.

BACKGROUND: Occupational risks for bladder cancer in hairdressers by using hair products have been examined in many epidemiological studies. But owing to small sample sizes of the studies and the resulting lack of statistical power, the results of these studies have been inconsistent and significant associations have rarely been found. METHODS: We conducted a meta-analysis to determine summary risk ratios (SRRs) for the risk of bladder cancer among hairdressers. Studies were identified by a MEDLINE, EMBASE, CENTRAL search and by the reference lists of articles/relevant reviews. Statistical tests for publication bias and for heterogeneity as well as sensitivity analysis were applied. In addition, the study quality and the risk of bias were assessed using six criteria. RESULTS: 42 studies were included and statistically significantly increased risks around 1.3-1.7 were found for all but one analysis. The SRR increased with duration of employment from 1.30 (95% CI 1.15 to 1.48) for 'ever registered as hairdresser' to 1.70 (95% CI 1.01 to 2.88) for 'job held > or = 10 years'. No difference was found between the risk for smoking-adjusted data (SRR 1.35, 95% CI 1.13 to 1.61) and no adjustment (SRR 1.33, 95% CI 1.18 to 1.50). Studies assessed as being of high quality (n=11) and of moderate quality (n=31) showed similar SRRs. There was no evidence of publication bias or heterogeneity in all analyses. CONCLUSION: In summary, our results showed an increased and statistically significant risk for bladder cancer among hairdressers, in particular for hairdressers in jobs held > or = 10 years. Residual confounding by smoking cannot be totally ruled out. Because of the long latency times of bladder cancer it remains an open question whether hairdressers working prior to 1980 and after 1980, when some aromatic amines were banned as hair dye ingredients, have the same risk for bladder cancer.
