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.

Cost-Benefit of Real-Time Multiplex PCR Testing of SARS-CoV-2 in German Hospitals.

BACKGROUND: The current Omicron COVID-19 pandemic has significant morbidity worldwide. OBJECTIVE: Assess the cost-benefit relation of implementing PCR point-of-care (POCT) COVID-19 testing in the emergency rooms (ERs) of German hospitals and in the case of inpatient admission due to other acute illnesses. METHODS: A deterministic decision-analytic model simulated the incremental costs of using the Savanna® Multiplex RT-PCR test compared to using clinical judgement alone to confirm or exclude COVID-19 in adult patients in German ERs prior to hospitalization or just prior to discharge. Direct and indirect costs were evaluated from the hospital perspective. Nasal or nasopharyngeal swabs of patients suspected to have COVID-19 by clinical judgement, but without POCT, were sent to external labs for RT-PCR testing. RESULTS: In probabilistic sensitivity analysis, assuming a COVID-19 prevalence ranging between 15.6-41.2% and a hospitalization rate between 4.3-64.3%, implementing the Savanna® test saved, on average, €107 as compared to applying the clinical-judgement-only strategy. A revenue loss of €735 can be avoided when SARS-CoV-2 infection in patients coming unplanned to the hospital due to other acute illnesses are excluded immediately by POCT. CONCLUSIONS: Using highly sensitive and specific PCR-POCT in patients suspected of COVID-19 infection at German ERs may significantly reduce hospital expenditures.

COVID-19 as an Occupational Disease-Temporal Trends in the Number and Severity of Claims in Germany.

COVID-19 is considered an occupational disease (OD), when infection occurs at the workplace for health workers (HW). Because of the increased infection risk of these workers, they were deemed to be a priority group when the vaccination campaign started in Germany in December 2020. By December 2021, more than 90% of HW had been vaccinated twice. We studied the number and the time trend concerning the severity of OD claims related to COVID-19. Workers' compensation claims for OD are recorded in a standardized database of the Statutory Accident Insurance and Prevention in the Health and Welfare Services (BGW). We analyzed all notifiable COVID-19 related claims filed between 1 March 2020 and 30 September 2022. The proportion of severe cases was estimated by inpatient stays, injury benefit payments, rehabilitation measures, and deaths. The data analysis was descriptive. Due to COVID-19, 317,403 notifiable cases were reported to the BGW. Of these, 200,505 (63.2%) had thus far been recognized as OD. The number of notifiable cases was highest in 2022 and lowest in 2020. In total, 3289 insured individuals were admitted to rehabilitation management. This represented 1.6% of all recognized ODs due to COVID-19 at the BGW. The proportion of cases admitted to rehabilitation management decreased from 4.5% of all recognized ODs in 2020 to 3.2% in 2021 and to 0.1% of all recognized cases in 2022. For inpatient stays, injury benefit payment, and death, a similar trend was observed. Therefore, it might be concluded that the successful vaccination campaign mitigated the negative health effects of COVID-19 on HW. Even with vaccination, severe cases can occur. Therefore, infection prevention at the workplace remains paramount.

Prevalence of Adverse Skin Reactions in Nursing Staff Due to Personal Protective Equipment during the COVID-19 Pandemic.

In order to prevent the nosocomial transmission of the SARS-CoV-2 virus, it has become necessary for health workers to increase their use of personal protective equipment (PPE). The aim of the study was to investigate the prevalence and influencing factors for adverse skin reactions (ASR) due to occupational PPE use among nursing staff in Germany during the COVID-19 pandemic. The study uses a mixed methods design. A focus group was created with experts from the field of healthcare, and an online survey was then carried out among nursing staff. Influencing factors were identified using multivariate logistic regression via odds ratios (ORs) with 95% confidence intervals (CIs). A total of 2274 nursing staff took part in the survey, with 1967 included in the analysis. The prevalence of ASR was 61%, with 94% affecting at least one area of the face. Statistically significant factors of influence were Filtering Face Peace (FFP) mask wearing duration of ≥4 h, a history of contact allergies, and being female and young. A pre-existing skin disease had a protective effect. The prevalence of PPE-related ASR underlines the necessity for targeted preventive measures for nursing staff during pandemic situation.

Coronavirus Vaccination: Spike Antibody Levels in Health Workers after Six Months-A Cross-Sectional Study.

Healthcare workers bear a high risk of infection during epidemics and pandemics such as the current SARS-CoV-2 pandemic. Various new vaccines have been approved. We investigated the influence of the time elapsed since vaccination, as well as of vaccination schema, on health workers' spike antibody levels following their second vaccination. Blood samples were obtained from employees working at a German hospital between August 2021 and December 2021 on average half a year (range 130-280 days) after their second vaccination. Levels of SARS-CoV-2-IgG antibodies (spike and nucleocapsid protein) were qualitatively detected via chemiluminescent immunoassays (CLIAs). A previous infection with SARS-CoV-2 was an exclusion criterion. In total, 545 persons were included in this cross-sectional study. Most participants (97.8%) showed elevated anti-spike concentrations. Anti-spike levels differed significantly among vaccination schemas. Repeated vector vaccinations resulted in lower protective antibody levels. Higher age levels, immunosuppression and a longer time period since the second vaccination resulted in lower anti-spike levels. Women's antibody levels were higher, but not significantly. Since anti-spike levels drop after vaccination, further boosters are required to increase immunoreactivity. If two vector vaccines have been administered, it is possible that an mRNA booster might increase the anti-spike level.

Experiences of Nurses in Nursing Homes during the COVID-19 Pandemic in Germany: A Qualitative Study.

(1) Background: The aim of this qualitative study was to examine pandemic-related changes in nursing work in nursing homes, the resulting work-related stresses and external as well as internal alleviating measures. (2) Methods: We conducted 10 interviews from March to June 2021 with nurses from eight facilities. Data were analysed according to qualitative content analysis. (3) Results: Nurses faced increased workloads due to regulations and guidelines paired with staffing shortages. Work became more difficult due to personal protective equipment (PPE), conflict with residents' relatives and, in the case of outbreaks, excess death and suffering. Nurse-to-resident care work became more emotionally demanding, with residents more distressed due to the lockdown, while families and social workers were not allowed into the facility. Residents with dementia posed an additional challenge, as they did not remember hygiene and distancing rules. Internal and external measures were not sufficient to alleviate the situation. However, some measures, such as training programmes or existing palliative care concepts, were considered helpful. (4) Conclusions: Facing other possible upcoming pandemics, ways to improve facility administration to prepare for future pandemics are highly needed, such as regular training programmes to prepare for possible lockdown scenarios, PPE use or potential hygiene measures.

Long-Term Effects of COVID-19 on Workers in Health and Social Services in Germany.

Health workers are at increased risk for SARS-CoV-2 infections. What follows the acute infection is rarely reported in the occupational context. This study examines the employees' consequences of COVID-19 infection, the risk factors and the impact on quality of life over time. In this baseline survey, respondents were asked about their COVID-19 infection in 2020 and their current health situation. Out of 2053 participants, almost 73% experienced persistent symptoms for more than three months, with fatigue/exhaustion, concentration/memory problems and shortness of breath being most frequently reported. Risk factors were older age, female gender, previous illness, many and severe symptoms during the acute infection, and outpatient medical care. An impaired health-related quality of life was found in participants suffering from persistent symptoms. Overall, a high need for rehabilitation to improve health and work ability is evident. Further follow-up surveys will observe the changes and the impact of vaccination on the consequences of COVID-19 among health workers.

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.

Balancing social and economic factors - explorative qualitative analysis of working conditions of supervisors in German social firms.

BACKGROUND: Social firms are companies on the general labour market which provide employment to people with severe disabilities. In this setting different job resources are offered for its employees, including social support or flexibility in terms of working hours, tasks or pace of work. However, to date, only limited evidence exists on the work and health situation of supervisors in social firms. Therefore, the study aims to explore job demands and resources of supervisors in social firms to increase knowledge in a little researched field and to develop recommendations for action on workplace health promotion. METHODS: Sixteen semi-structured telephone interviews were conducted with supervisors of social firms in the North of Germany within July and November 2020. Different sectors such as gastronomy or cleaning services as well as employment opportunities for people with different types of disabilities were included. The interviews were recorded, transcribed verbatim and analysed following the qualitative content analysis according to Mayring (deductive-inductive approach). RESULTS: Overall, a heterogeneous composition was aimed for in terms of age and gender distribution (68.75% were male and between 32 and 60 years old). Supervisors reported various job demands in social firms, including for instance emotional demands, conflicts between social and economic objectives, conflict management, exposure to heat, heavy lifting or constant standing. In contrast, a high meaning of work, possibilities in shaping the structure of the social firm, social support of colleagues or the management and the provision of an ergonomic work environment were highlighted as job resources. Further person-related demands (e.g. own expectations) and resources (e.g. patience) were underlined as well. CONCLUSION: First exploratory insights were provided with reference to job demands and resources for supervisors in social firms. The overview on working conditions underlines the significance of a supportive work environment taking structural and behavioural-related implications into account to reduce demands and strengthen resources. Further interventional research is needed regarding the development, testing and evaluation of workplace health promotion interventions in social firms.

Cumulative Incidence of SARS-CoV-2 in Healthcare Workers at a General Hospital in Germany during the Pandemic-A Longitudinal Analysis.

Health workers (HW) are at increased risk for SARS-CoV-2 infection. In order to monitor the infection dynamic on the basis of contact with patients, HW at the St. Antonius Hospital (SAH) were tested four times in one year by PCR and serology. The cumulative incidence of infection in HW was calculated. Swab and blood tests were simultaneously performed between April 2020 and April 2021. Risk factors and demographic information were assessed at the beginning of the study. The response rate was above 75% in all rounds of testing. The study comprised 1506 HW, 165 (10.6%) of which tested positive for SARS-CoV-2 infection. Working in an ICU or on wards with patient contact were risk factors (OR 4.4, 95% CI 1.73-13.6 and OR 2.9, 95% CI 1.27-8.49). At the end of the study, the majority of HW (810 of 1363 (59.4%)) had been vaccinated at least once. A total of 29.1% of unvaccinated HW and 5.3% of vaccinated HW showed an immune response typical for natural SARS-CoV-2 infection. Of the 73 HW who provided information on the course of the disease, 31.5% reported that their quality of life continued to be impaired. The cumulative incidence of infection was low in these HW, which may be attributed to vaccination and good hygiene. Nevertheless, a work-related infection risk was identified, highlighting the need to improve protection against infection. A high risk of developing long COVID was found after the infection has subsided. Special rehabilitation programs should be provided and HW should be compensated for reduced work capacity in the case that rehabilitation fails or takes a long time.

The isolated effect of age on the risk of COVID-19 severe outcomes: a systematic review with meta-analysis.

INTRODUCTION: Increased age has been reported to be a factor for COVID-19 severe outcomes. However, many studies do not consider the age dependency of comorbidities, which influence the course of disease. Protection strategies often target individuals after a certain age, which may not necessarily be evidence based. The aim of this review was to quantify the isolated effect of age on hospitalisation, admission to intensive care unit (ICU), mechanical ventilation and death. METHODS: This review was based on an umbrella review, in which Pubmed, Embase and preprint databases were searched on 10 December 2020, for relevant reviews on COVID-19 disease severity. Two independent reviewers evaluated the primary studies using predefined inclusion and exclusion criteria. The results were extracted, and each study was assessed for risk of bias. The isolated effect of age was estimated by meta-analysis, and the quality of evidence was assessed using Grades of Recommendations, Assessment, Development, and Evaluation framework. RESULTS: Seventy studies met our inclusion criteria (case mortality: n=14, in-hospital mortality: n=44, hospitalisation: n=16, admission to ICU: n=12, mechanical ventilation: n=7). The risk of in-hospital and case mortality increased per age year by 5.7% and 7.4%, respectively (effect size (ES) in-hospital mortality=1.057, 95% CI 1.038 to 1.054; ES case mortality=1.074, 95% CI 1.061 to 1.087), while the risk of hospitalisation increased by 3.4% per age year (ES=1.034, 95% CI 1.021 to 1.048). No increased risk was observed for ICU admission and intubation by age year. There was no evidence of a specific age threshold at which the risk accelerates considerably. The confidence of evidence was high for mortality and hospitalisation. CONCLUSIONS: Our results show a best-possible quantification of the increase in COVID-19 disease severity due to age. Rather than implementing age thresholds, prevention programmes should consider the continuous increase in risk. There is a need for continuous, high-quality research and 'living' reviews to evaluate the evidence throughout the pandemic, as results may change due to varying circumstances.

Workplace Health Promotion and COVID-19 Support Measures in Outpatient Care Services in Germany: A Quantitative Study.

Working conditions in the care sector, especially under the increased strain during COVID-19, make it difficult for outpatient caregivers to adhere to health-promoting behaviours. Research on workplace health promotion (WHP) and COVID-19 support measures in outpatient care services is limited. The aim of this pilot study was to characterise the current situation of WHP and COVID-19 support measures in outpatient care services and to explore how to offer WHP support measures targeted for a specific group. A web-based cross-sectional survey was conducted with outpatient caregivers (N = 171) in northern Germany. The results showed that 60.2% of the study participants were offered WHP support measures, with significantly higher work engagement when WHP support measures were available (Z = 4279.50, p < 0.01) and that 77.2% received specific support from their employer during the COVID-19 pandemic. Although spending a break in a break room was significantly associated with longer breaks as compared with being in a car (Z = 39.10, padj. = 0.01), a break room was neither available in all outpatient care services, nor did it appear to be feasible. Overall, WHP in outpatient care services is insufficiently covered. In order to be able to offer WHP support measures that are targeted to outpatient caregivers, cooperation among local care services, feasibility, and digital measures should be examined.

The Role of Health Literacy among Outpatient Caregivers during the COVID-19 Pandemic.

Health literacy became an important competence during the COVID-19 pandemic. Despite outpatient caregivers being a particularly vulnerable occupational group, their health literacy has hardly been examined yet, especially during the pandemic. Hence, this study aimed to explore this field and provide first empirical insights. Data were collected based on a cross-sectional online survey among 155 outpatient caregivers. In particular, health literacy (HLS-EU-Q16), diet and physical activity, pandemic-related worries, perceived information sufficiency and stress perception were examined. Descriptive and ordinal logistic regression analyses were run to test explorative assumptions. The majority of outpatient caregivers reported high values of health literacy (69% on a sufficient level). Although no significant associations between health literacy and health behaviours or perceived information sufficiency were found, perceived information sufficiency and perceived stress (OR = 3.194; 95% CI: 1.542-6.614), and pandemic-related worries (OR = 3.073; 95% CI: 1.471-6.421; OR = 4.243; 95% CI: 2.027-8.884) seem to be related. Therefore, dissemination of reliable information and resource-building measures to reduce worries may be important parameters for improving outpatient caregivers' health. Our results provide first explorative insights, representing a starting point for further research. Considering outpatient caregivers' mobile work setting, they need to be provided with adequate equipment and comprehensible information to ensure physically and mentally healthy working conditions.

Long term effects of COVID-19 in health workers and the assessment of the fatigue syndrome in compensation claims

IntroductionIn Germany more than 45,000 cases of COVID-19 are already recognized as Occupational Disease (OD) for workers in the health and welfare sector. Different long term effects of COVID-19 are described in literature, fatigue being one of the most common symptoms observed after the infection.ObjectivesWe assessed long term effects of COVID-19 three months and more after the SARS-CoV-2 infection in health and social workers (HSW).MethodsA self-administered questionnaire was sent to 3,800 HSW with COVID-19 recognized as OD in January 2021. The questionnaire was self-developed and assessed biographical data, symptoms at time of infection, quality of life (QoL) and workability as well as COVID-19 associated symptoms three months or more after infection. The study was approved by the Medical Ethic Committee in Hamburg, Germany.ResultsA total of 2,018 HSW returned the questionnaire. Response rate was 53%. 82% were female and 52% were older than 50 years. 42% worked in hospitals and 30% in nursing homes, 9% were doctors and 56% nurses. Compared to the time before the infection, QoL was reduced by 72% and work ability was reduced by 83%. Severe fatigue was reported by 20%, sever concentration and memory problems by 14% and severe breathlessness by 9%. 4.5% had already taken part in a rehabilitation and 37% wished to take part in a rehabilitation.ConclusionLong term fatigue symptoms are common in HSW more than three months after COVID-19. The need for rehabilitation in HSW with COVID-19 as OD is high. The further cause and the treatment options for long term effects and especially for fatigue need to be studied.

Point-of-Care COVID-19 Antigen Testing in Exposed German Healthcare Workers-A Cost Model.

BACKGROUND: Hospital staffing shortages are again (mid-year 2021) becoming a significant problem as the number of positive COVID-19 cases continues to increase worldwide. OBJECTIVE: To assess the costs of sending HCW into quarantine (Scenario 1) from the hospital's and the taxpayer's perspective versus the costs arising from implementing point-of-care COVID-19 antigen testing (POCT) for those staff members who, despite learning that they have been exposed to hospital patients later found to be infected with COVID-19, continue to report to work (Scenario 2). METHODS: A mathematical model was built to calculate the costs of a sample-and-stay strategy for exposed healthcare workers (HCW) in Germany by utilizing a high-quality antigen fluorescent immunoassay (FIA), compared to the costs of quarantine. Direct costs and wage costs were evaluated from the hospital as well as from the taxpayer perspective assuming a SARS-CoV-2 infection prevalence of 10%. RESULTS: Serial POCT testing of exposed HCW in Germany (Scenario 2) who do not go into quarantine but continue to work during a post-exposure period of 14 days at their working place raises costs of EUR 289 (±20%: EUR 231 to EUR 346, rounded) per HCW at the expense of the employing hospital while the extra-costs to the taxpayer per exposed HCW are limited to EUR 16 (±20%: EUR 13 to EUR 19). In contrast, sending HCW into quarantine (Scenario 1) would result in costs of EUR 111 (±20%: EUR 89 to EUR 133) per exposed HCW for the hospital but EUR 2235 (±20%: EUR 1744 to EUR 2727) per HCW at the expense of the taxpayer. CONCLUSIONS: Monitoring exposed HCW who continued working by sequential POCT may considerably reduce costs from the perspective of the taxpayer and help mitigate personnel shortages in hospitals during pandemic COVID-19 waves.

Occupational Infections among Dental Health Workers in Germany-14-Year Time Trends.

Dental health workers (DHW) are at increased risk of acquiring occupational infections. Due to various protective measures, it can be assumed that infections have decreased over the past 14 years. Secondary data from a German accident insurance company was analyzed in terms of reported and confirmed occupational diseases (OD) in DHW from 2006 to 2019. A total of 271 claims were reported, of which 112 were confirmed as OD, representing an average of eight per year. However, the number of claims and confirmed ODs has decreased by 65.6% and 85.7%, respectively. The decrease was most evident for hepatitis B (HBV) and C (HCV) infections, while tuberculosis (TB) infections were stable. A total of 44 HCV, 33 HBV, 6 TB and 24 latent TB infections were confirmed as ODs. For DHW, 0.05, and for hospital workers, 0.48 claims per 1000 full-time equivalents (FTE) were registered in 2019. In a separate documentation system, between March 2020 and February 2021, 155 COVID-19 claims were registered, and 47 cases were confirmed as ODs. For DHW, 0.7, and for hospital workers, 47.3 COVID-19 claims per 1000 FTE were registered since 2020. Occupational infectious diseases rarely occur among DHW. Nevertheless, new infectious diseases such as COVID-19 pose a major challenge for DHW. Continued attention should be paid to infectious disease prevention.

COVID-19 among Health Workers in Germany-An Update.

This is an update of our report on COVID-19 among health and social welfare workers in Germany. Workers' compensation claims for occupational diseases (OD) are recorded in a standardized database of the Statutory Accident Insurance and Prevention in the Health and Welfare Services (BGW). We analyzed which workers in the health and welfare sector are most often affected by COVID-19. For the different sectors in healthcare and welfare, the number of full-time workers is known (FTW), allowing for calculation of claim rates by sector. The period for data presentation was extended to 3 May 2021 for this update. The cumulative number of COVID-19 claims increased from 4398 by May 2020 to 84,728 by May 2021. The majority of claims concern nursing homes (39.5%) and hospitals (37.6%). Nursing is the profession most often concerned (68.8%). Relative to the number of workers, the claim rate is highest for hospitals (41.3/1000 FTW). Seventy-seven workers died (0.09%) and three hundred and seventy-five (0.4%) were hospitalized. A total of 65,693 (77.5%) claims were assessed, and for 81.4% of these claims, the OD was confirmed. The number of health and welfare workers affected by COVID-19 is high. With most HW vaccinated by now in Germany, within the next few weeks or months, the number of new cases should decrease.

[Implementation of occupational health and safety during the SARS-CoV-2 pandemic in hairdressers' salons]. / Umsetzung des Arbeitsschutzes während der SARS-CoV-2-Pandemie in Friseursalons.

BACKGROUND: There is little empirical evidence with respect to the implementation (adherence) of occupational health and safety guidelines in Germany. Recommendations for the prevention of SARS-CoV­2 infections in hairdressing services were provided by the German Statutory Accident Insurance for the Health and Welfare Services (BGW) in an occupational health and safety (OHS) standard in spring 2020. RESEARCH QUESTION: To what extent are the recommendations adhered to in this service profession as judged by hairdresser's customers after their visits? MATERIAL AND METHODS: The survey was conducted as a covert participant observational study between the beginning of October and the middle of December 2020 as a non-systematic opportunistic sample in three cities. The standardized checklist included three domains: a) measures of general, mainly technical nature, b) in contact with the customer and c) on an individual level for infection prevention.The results on domain and overall level were summarized in a standardized sum index (0-1) of SARS-CoV­2 OHS standard adherence. Nonparametric Wilcoxon tests were used to examine possible differences among the three subindices. RESULTS: The overall adherence index of 162 observations was 0.75 (SD 0.14). The two subindices on infection prevention in contact with the customer (e.g. indications for behavior rules) and on the individual level (e.g. wearing a mouth-nose covering) were significantly better than the one on general measures (e.g., hand cleaning possibility for customers). DISCUSSION: The observed adherence for prevention of SARS-CoV-2-infections in hairdresser salons was higher than experiences of the BGW on OHS adherence suggest. This might be explained by the general public awareness of risks of infection. The results on the adherence are only slightly lower than those resulting from around 400 standardized personal surveys of the BGW prevention services. LIMITATIONS: Given the non-systematic opportunistic sample, a (positive) bias in the adherence results cannot be excluded.

The Health Behaviour of German Outpatient Caregivers in Relation to the COVID-19 Pandemic: A Mixed-Methods Study.

The COVID-19 pandemic has affected outpatient caregivers in a particular way. While the German population becomes increasingly older, the number of people in need of care has also increased. The health and, thus, the health behaviour of employees in the outpatient care become relevant to maintain working capacity and performance in the long term. The aims of the study were (1) to examine the health behaviour and (2) to explore pandemic-related perceived change of health behaviour among outpatient caregivers during the COVID-19 pandemic. In a mixed-methods study, 15 problem-centred interviews and a web-based cross-sectional survey (N = 171) were conducted with outpatient caregivers working in Northern Germany. Interviewees reported partially poorer eating behaviour, higher coffee consumption, lower physical activity, skipping breaks more often and less sleep duration and quality during the pandemic. Some quantitative findings indicate the same tendencies. A majority of participants were smokers and reported higher stress perception due to the pandemic. Preventive behaviour, such as wearing PPE or hand hygiene, was increased among interviewees compared to the pre-pandemic period. Our findings indicate that the COVID-19 pandemic could negatively affect outpatient caregivers' health behaviour, e.g., eating/drinking behaviour and physical activity. Therefore, employers in outpatient care should develop workplace health promotion measures to support their employees in conducting more health-promoting behaviours during the COVID-19 pandemic.

Latent Tuberculosis Infection among Health Workers in Germany-A Retrospective Study on Progression Risk and Use of Preventive Therapy.

Despite the decline in tuberculosis incidence (TB) in Germany, health workers (HW) are at greater risk of becoming infected with Mycobacterium tuberculosis. To date, little is known about the risk of progression of latent tuberculosis infections (LTBI) and the use of Tuberculosis Preventive Therapy (TPT) among HW. Routine data from the German Statutory Institution for Accident Insurance and Prevention for Health and Welfare Services (BGW) were analysed and a retrospective survey was conducted. A self-administered questionnaire was sent to 1711 HW who had received recognition of an LTBI as an occupational disease between the years 2009 and 2018. The response rate was 42.3% after correcting for those with no actual address (20.4%). We included 575 HW in the data analysis of the retrospective survey. The cumulative incidence of progression, the incidence density and the associated 95% confidence interval (95% CI) were calculated. Three progressive cases were identified in the analysis of the routine data. In the survey cohort, three HW developed TB during the observation period of 5.4 years on average (standard deviation: 2.8 years; interquartile range: 5.0 years). The cumulative TB incidence was 0.52% in the survey group (95% CI: 0.14% to 1.65%). The incidence density was 0.97 cases per 1000 person years (95% CI: 0.25 to 3.10). One-third of the respondents underwent TPT. Significant differences were observed between age and activity groups in the use of TPT, but not between the genders, year of diagnosis or the reason for performing the screening. The data indicate that the risk of progression of an LTBI is low for HW. However, one-third of the HW had undergone TPT. Information about the expected progression risk is important so that it can be weighed against the risk of side effects of TPT.
