Recognition of COVID-19 with occupational origin: a comparison between European countries.

OBJECTIVES: This study aims to present an overview of the formal recognition of COVID-19 as occupational disease (OD) or injury (OI) across Europe. METHODS: A COVID-19 questionnaire was designed by a task group within COST-funded OMEGA-NET and sent to occupational health experts of 37 countries in WHO European region, with a last update in April 2022. RESULTS: The questionnaire was filled out by experts from 35 countries. There are large differences between national systems regarding the recognition of OD and OI: 40% of countries have a list system, 57% a mixed system and one country an open system. In most countries, COVID-19 can be recognised as an OD (57%). In four countries, COVID-19 can be recognised as OI (11%) and in seven countries as either OD or OI (20%). In two countries, there is no recognition possible to date. Thirty-two countries (91%) recognise COVID-19 as OD/OI among healthcare workers. Working in certain jobs is considered proof of occupational exposure in 25 countries, contact with a colleague with confirmed infection in 19 countries, and contact with clients with confirmed infection in 21 countries. In most countries (57%), a positive PCR test is considered proof of disease. The three most common compensation benefits for COVID-19 as OI/OD are disability pension, treatment and rehabilitation. Long COVID is included in 26 countries. CONCLUSIONS: COVID-19 can be recognised as OD or OI in 94% of the European countries completing this survey, across different social security and embedded occupational health systems.

[Economic cost estimation of a sample of occupational disease cases accepted by the National Institute of Social Security and evaluated at Parc de Salut Mar, 2014-2021]. / Estimación económica de una muestra de casos de enfermedad profesional confirmados por el Instituto Nacional de la Seguridad Social atendidos en el Parc de Salut Mar, 2014-2021.

Underreporting of occupational diseases (OD) is a social and economic problem, because it has negative consequences for both the welfare of the affected workers and its impact on budgetary planning for the management of health services. We evaluated the healthcare costs of a sample of 13 cases of OD treated at a public hospital in Barcelona between 2014 and 2021, and officially accepted by the National Institute of Social Security (INSS). The total cost of care was €474,859, with an average cost of €36,528 per patient. By diagnostic group, the highest costs were associated with cancer cases, accounting for 79% of the total (€375,068). The findings of this study reflect the economic impact of health care provided by a public hospital to patients with an OD recognized by the INSS.

La infranotificación de enfermedades profesionales (EEPP) es un problema social y económico, pues repercute en el bienestar del trabajador afectado, y en las estimaciones presupuestarias que se planifican anualmente para la gestión de los servicios sanitarios. Los costes asistenciales fueron evaluados en una muestra de 13 casos de EEPP con resolución positiva por el Instituto Nacional de la Seguridad Social atendidos en el Parc de Salut Mar (Barcelona) entre 2014 y 2021. El coste de la asistencia generada del total de casos fue de 474.859 €, con un coste medio de 36.528 € por paciente. Por grupo diagnóstico, el coste más alto lo originaron los casos de cánceres que supusieron el 79% del gasto total (375.068 €). Los hallazgos del estudio reflejan el impacto económico que supone la asistencia sanitaria prestada por un hospital público a pacientes con una EEPP reconocida en el INSS.

Waiting time from identification to recognition an occupational disease in Spain.

OBJECTIVE: To estimate the waiting time since a suspected an occupational disease (OD) is identified, notified and recognized in Spain. METHOD: A series of 34 patients attended at Occupational Diseases Unit (ODU) of Hospital del Mar in Barcelona were follow up since their identification until final resolution by the National Institute of Social Security (INSS). Median, and 25 and 75 percentiles (interquartile range [IQR]) were calculated in weeks by total time (n=27), ODU time (n=34), patient time (n=31) and INSS time (n=27). RESULTS: Total time was 51 weeks (IQR: 33.6 and 122.6), of which 42 weeks (17.6-99.5) corresponded to the waiting period at the INSS. CONCLUSIONS: The disproportionately long waiting time since INSS receives a case could impact on the under-recognition of OD. Urgent improvement of the administrative process is needed to reduce the patient waiting time for the recognition of OD.

[Approximation to the cost of occupational diseases treated in seven hospitals in Spain]. / Aproximación al coste de enfermedades profesionales atendidas en siete hospitales en España.

OBJECTIVE: To estimate the hospital cost of a sample of cases treated in seven hospitals of the National Health System in several Spanish cities. METHOD: Study based on 78 cases of occupational disease recognized by the social security, and previously treated in hospitals in Badalona, Barcelona, Ferrol, Gijón, Girona, Madrid and Vigo between 2017 and 2019. RESULTS: The healthcare activity generated by these hospitals to attend these processes involved a total cost of 282,927€. CONCLUSIONS: It is urgent to improve the coordination between the two public health systems, the social security health care system and the National Health System.

[Health care costs of occupational disease: analysis of a patient series at a public hospital]. / Costes sanitarios de las enfermedades profesionales: análisis de una serie de pacientes de un hospital público.

The consistent under-recognition of occupational diseases (OD) in Spain leads to an exchange of patients and resources between the country's National Health System and the Social Security System. We examined the direct healthcare costs of a series of patients diagnosed with OD by the Clinical Occupational Diseases Unit in a Barcelona hospital. Information on all care associated with the diagnosis of PD was systematically reviewed. The economic value of each episode of care was obtained from the hospital cost accounting and billing system. Overall, we computed costs for 524 episodes in 33 patients. The average cost was 345.5€, being highest for hospital admissions (4,032.5€). The average cost per patient was € 5,486.2, and for cancer € 15,223.3. These results highlight the need for coordination between the National Health System and the Social Security System so that OD can be appropriately recognized.

El infra-reconocimiento secular de las enfermedades profesionales (EP) en España provoca un intercambio de pacientes y recursos entre el Sistema Nacional de Salud y el de Seguridad Social. Se estimaron los costes asistenciales directos de una serie de pacientes de un hospital de Barcelona diagnosticados de EP por su Unidad de Patología Laboral. La información sobre todas las asistencias asociadas al diagnóstico de EP fue revisada sistemáticamente. El valor económico de cada asistencia se obtuvo de la contabilidad de costes y sistema de facturación del hospital. En total, se computaron 524 asistencias de 33 pacientes, con un coste medio de 345,5€, siendo el más alto para las hospitalizaciones (4.032,5€). El coste medio por paciente fue de 5.486,2€, y para el cáncer de 15.223,3€. Estos resultados ponen de manifiesto la necesidad de coordinación entre el Sistema Nacional de Salud y el de Seguridad Social para un adecuado reconocimiento de EP.

What can public health do for the welfare state? Occupational health could be an answer.

BACKGROUND: The welfare state has a long history of uncertain future. Nonetheless, health indicators of people living in countries with a more universal and generous welfare state remain better than those living under less generous and more individualist welfare regimes. In this essay, we reflect on how occupational health, as part of public health, can contribute to the sustainability of the welfare state. METHODS: Over the course of the political and social transformations of the State, from single guarantor of security to assuming civil and social rights, the practice of public health has added, to its original objectives related to the control of epidemics of contagious diseases, the promotion of health and the reduction of inequalities in health. In the context of the 2030 Agenda of Sustainable Development Goals, there is a great opportunity to expand the welfare state through public health policies. RESULTS: On the other hand, the welfare state is only possible when persons are employed in the formal sector. Through their taxes, workers and employers support the welfare state. Occupational health, by preventing injury and illness, and promoting the health of working people, can contribute significantly to the existence of decent work and a quality labour market. CONCLUSION: The mission of occupational health is to help people enjoy a healthy and prolonged working life, as a critical component of human well-being.

Determinants of international variation in the prevalence of disabling wrist and hand pain.

BACKGROUND: Previous research has indicated that wide international variation in the prevalence of disabling low back pain among working populations is largely driven by factors predisposing to musculoskeletal pain more generally. This paper explores whether the same applies to disabling wrist/hand pain (WHP). METHODS: Using data from the Cultural and Psychosocial Influences on Disability (CUPID) study, we focused on workers from 45 occupational groups (office workers, nurses and other workers) in 18 countries. Among 11,740 participants who completed a baseline questionnaire about musculoskeletal pain and potential risk factors, 9082 (77%) answered a further questionnaire after a mean interval of 14 months, including 1373 (15%) who reported disabling WHP in the month before follow-up. Poisson regression was used to assess associations of this outcome with baseline risk factors, including the number of anatomical sites other than wrist/hand that had been painful in the 12 months before baseline (taken as an index of general propensity to pain). RESULTS: After allowance for other risk factors, the strongest associations were with general pain propensity (prevalence rate ratio for an index ≥6 vs. 0: 3.6, 95% confidence interval 2.9-4.4), and risk rose progressively as the index increased. The population attributable fraction for a pain propensity index > 0 was 49.4%. The prevalence of disabling WHP by occupational group ranged from 0.3 to 36.2%, and correlated strongly with mean pain propensity index (correlation coefficient 0.86). CONCLUSION: Strategies to prevent disability from WHP among working populations should explore ways of reducing general propensity to pain, as well as improving the ergonomics of occupational tasks.

A hospital occupational diseases unit: an experience to increase the recognition of occupational disease.

BACKGROUND: Under-reporting and recognition of occupational diseases is a problem in countries with workers' compensation schemes. OBJECTIVE: To describe the role of a public hospital Occupational Disease Unit (ODU) in Barcelona that resulted in improved reporting and official recognition of occupational diseases from 2010 to 2017. METHODS: Hospital physicians referred possible cases of work-related disease to the ODU, where in-depth medical evaluations were then performed, and a detailed report addressing causation was generated. Patients with confirmed cases of occupational disease were counselled and followed while pursuing official recognition and benefits claims by the Spanish Social Security System. RESULTS: Between 2010 and 2017, 149 cases were referred to the ODU for evaluation. Of these, 80 (53.7%) were confirmed to have an occupational disease, 54 (67.5%) patients pursued official recognition, and to date 26 (48.1%) have been recognized by the Social Security System. The recognition rate varied by diagnosis group (p=0.003), and was highest for skin diseases (71.4%) and cancer (66.7%), and lowest for hearing loss (29.4%) and musculoskeletal disorders (16.7%). CONCLUSIONS: A hospital ODU can improve reporting and official recognition of occupational diseases that otherwise might not have been recognized. Expanding this experience to other Spanish and European hospitals could improve the efficiency of workers' compensation schemes and better support preventive policies.

Prevention and management of musculoskeletal pain in nursing staff by a multifaceted intervention in the workplace: design of a cluster randomized controlled trial with effectiveness, process and economic evaluation (INTEVAL_Spain).

BACKGROUND: Musculoskeletal pain (MSP) is the leading cause of years lived with disability. In consequence, to reduce MSP and its associated sickness absence is a major challenge. Previous interventions have been developed to reduce MSP and improve return to work of workers with MSP, but combined approaches and exhaustive evaluation are needed. The objective of the INTEVAL_Spain project is to evaluate the effectiveness of a multifaceted intervention in the workplace to prevent and manage MSP in nursing staff. METHODS: The study is designed as a two-armed cluster randomized controlled trial with a late intervention control group. The hospital units are the clusters of randomization and participants are nurses and aides. An evidence-based multi-component intervention was designed combining participatory ergonomics, case management and health promotion. Both the intervention and the control groups receive occupational health care as usual. Data are collected at baseline, and after six and 12 months. The primary outcomes are prevalence of MSP and incidence and duration of sickness absence due to MSP. Secondary outcomes are work role functioning and organizational preventive culture. The intervention process will be assessed through quantitative indicators of recruitment, context, reach, dose supplied, dose received, fidelity and satisfaction, and qualitative approaches including discussion groups of participants and experts. The economic evaluation will include cost-effectiveness and cost-utility, calculated from the societal and the National Health System perspectives. DISCUSSION: Workplace health programs are one of the best options for the prevention and control of non-communicable diseases. The main feature of this study is its multifaceted, multidisciplinary and de-medicalized intervention, which encompasses three evidence-based interventions and covers all three levels of prevention, which have not been previously unified in a single intervention. Also, it includes a comprehensive quantitative and qualitative evaluation of the intervention process, health results, and economic impact. This study could open the possibility of a new paradigm for the prevention and management of MSP and associated sickness absence approach at the workplace. TRIAL REGISTRATION: Current Controlled Trials ISRCTN15780649 Retrospectively registered 13th July 2018.

[Occupational risk during pregnancy and sick leave in a cohort of workers from Parc de Salut Mar (Barcelona, Spain)]. / Prestación por riesgo durante el embarazo e incapacidad temporal en una cohorte de trabajadoras del Parc de Salut Mar (Barcelona, España).

OBJECTIVE: To study the use of the Pregnancy occupational risk benefit (PORB) and non-work related sickness absence (NWSA) in a cohort of pregnant workers of Parc de Salut Mar, Barcelona (Spain). METHOD: Retrospective cohort study of 428 pregnant workers between 2010 and 2014, who were followed-up until delivery. Absences from work, both PORB and NWSA were recorded until the beginning of their maternity leave. The sequence analysis identifies four trajectories, which are described according to workers demographic and job characteristics. RESULTS: Of the total cohort, 56 (13.1%) accessed only the PORB, representing 6.126 days of absence; 68 (15.9%) also accessed PORB, with 7.127 days of absence, but had previously accumulated 102 episodes of NWSA with 1.820 days of absence. The majority of pregnant workers in the sample (69.9%) took only one or several episodes of NWSA without using PORB, with 545 episodes and 26,337 days of absence. Most were active during the first quarter and it is from the second quarter that episodes of long-term NWSA appeared. During the last month of pregnancy more than 80% of the workers were absent from work. CONCLUSIONS: Pregnant workers remained at work for two thirds of their pregnancy. Absences were mainly due to episodes of NWSA. PORB represented one third of them. As in other similar countries, our results suggest a change in the management of social protection benefits for pregnant workers.

[Welfare State and public health: the role of occupational health]. / Estado de bienestar y salud pública: el papel de la salud laboral.

In the context of the current crisis of the Welfare State, occupational health can contribute significantly to its sustainability by facilitating decent and healthy employment throughout the working life. To this end, occupational health must take on the challenge of promoting health, preventing and managing injuries, illnesses and disability, based on better coordination of prevention services, mutual insurance companies, and health services, as well as by empowering the leadership in prevention of companies and the active participation of those who work.

[Welfare State and public health: a relationship that needs to be updated]. / Estado del bienestar y salud pública, una relación que debe ser actualizada.

Human health has improved throughout the 20th century, at the same time that the Welfare State was consolidated. This paper explores the current relationship between the welfare state and public health. The essential functions of public health are exercised as part of the State, and currently the main challenge is to ensure that health is protected and promoted through different public policies, including employment. Studies assessing the health effect of different types of welfare state are contradictory, but when the impact of specific policies, such as unemployment benefits, is considered, the results are positive and consistent. However, the current crisis of the Welfare State hampers its continuity, largely due to changes in the labour market, with more flexible and insecure jobs.

[Identification of occupational risks associated with diseases suspected to be of possible occupational origin seen in the National Health System]. / Identificación de los riesgos laborales asociados a enfermedad sospechosa de posible origen laboral atendida en el Sistema Nacional de Salud.

In an earlier study, we identified 26 diseases of possible occupational origin, seen in different settings within the national health system in Catalonia. In this literature review we identify those occupational risk factors most strongly associated with these pathologies. After applying inclusion/exclusion criteria to 754 reviews, meta-analyses and/or practice guidelines, 37 articles remained that were rated for study quality by 3 reviewers. Of these, the 31 studies of highest quality were examined in depth, and summarised in a final table. Ergonomic risk factors (manual handling of materials, highly repetitive movements and awkward postures), especially for musculoskeletal disorders of the upper extremity, and exposures to chemical products and physical agents, were prominent. These results provide an additional resource for primary care physicians to assist them with the identification of possible occupational illness and to improve communication between the National Health Service and social security system.

Socioeconomic status and exposure to disinfection by-products in drinking water in Spain.

BACKGROUND: Disinfection by-products in drinking water are chemical contaminants that have been associated with cancer and other adverse effects. Exposure occurs from consumption of tap water, inhalation and dermal absorption. METHODS: We determined the relationship between socioeconomic status and exposure to disinfection by-products in 1271 controls from a multicentric bladder cancer case-control study in Spain. Information on lifetime drinking water sources, swimming pool attendance, showering-bathing practices, and socioeconomic status (education, income) was collected through personal interviews. RESULTS: The most highly educated subjects consumed less tap water (57%) and more bottled water (33%) than illiterate subjects (69% and 17% respectively, p-value = 0.003). These differences became wider in recent time periods. The time spent bathing or showering was positively correlated with attained educational level (p < 0.001). Swimming pool attendance was more frequent among highly educated subjects compared to the illiterate (odds ratio = 3.4; 95% confidence interval 1.6-7.3). CONCLUSIONS: The most highly educated subjects were less exposed to chlorination by-products through ingestion but more exposed through dermal contact and inhalation in pools and showers/baths. Health risk perceptions and economic capacity may affect patterns of water consumption that can result in differences in exposure to water contaminants.

Systematic review of the role of occupational health and safety interventions in the prevention of upper extremity musculoskeletal symptoms, signs, disorders, injuries, claims and lost time.

BACKGROUND: Little is known about the most effective occupational health and safety (OHS) interventions to reduce upper extremity musculoskeletal disorders (MSDs) and injuries. METHODS: A systematic review used a best evidence synthesis approach to address the question: "do occupational health and safety interventions have an effect on upper extremity musculoskeletal symptoms, signs, disorders, injuries, claims and lost time?" RESULTS: The search identified 36 studies of sufficient methodological quality to be included in data extraction and evidence synthesis. Overall, a mixed level of evidence was found for OHS interventions. Levels of evidence for interventions associated with positive effects were: Moderate evidence for arm supports; and Limited evidence for ergonomics training plus workstation adjustments, new chair and rest breaks. Levels of evidence for interventions associated with "no effect" were: Strong evidence for workstation adjustment alone; Moderate evidence for biofeedback training and job stress management training; and Limited evidence for cognitive behavioral training. No interventions were associated with "negative effects". CONCLUSION: It is difficult to make strong evidenced-based recommendations about what practitioners should do to prevent or manage upper extremity MSDs. There is a paucity of high quality OHS interventions evaluating upper extremity MSDs and none focused on traumatic injury outcomes or workplace mandated pre-placement screening exams. We recommend that worksites not engage in OHS activities that include only workstation adjustments. However, when combined with ergonomics training, there is limited evidence that workstation adjustments are beneficial. A practice to consider is using arm supports to reduce upper extremity MSDs.

Principles and methodology for translation and cross-cultural adaptation of the Nordic Occupational Skin Questionnaire (NOSQ-2002) to Spanish and Catalan.

BACKGROUND: Occupational skin diseases are among the most frequent work-related diseases in industrialized countries. The Nordic Occupational Skin Questionnaire (NOSQ-2002), developed in English, is a useful tool for screening of occupational skin diseases. OBJECTIVES: To culturally adapt the NOSQ-2002 to Spanish and Catalan and to assess the clarity, comprehension, cultural relevance and appropriateness of the translated versions. METHODS: The International Society for Pharmacoeconomics and Outcomes Research (ISPOR) principles of good practice for the translation and cultural adaptation of patient-reported outcomes were followed. RESULTS: After translation into the target language, a first consensus version of the questionnaire was evaluated in multiple cognitive debriefing interviews. The expert panel introduced some modifications in 39 (68%) and 27 (47%) items in the Spanish and Catalan version, respectively (e.g. addition of examples and definitions, reformulation of instructions and use of direct question format). This version was back translated and submitted to the original authors, who suggested a further seven and two modifications in the Spanish and Catalan versions, respectively. A second set of cognitive interviews were performed. A consensus version of both questionnaires was obtained after final modifications based on comments by the patients. CONCLUSIONS: The final versions of the Spanish and Catalan NOSQ-2002 questionnaires are now available at www.NRCWE.dk/NOSQ.

Micronuclei assessment in the urothelial cells of women using hair dyes and its modulation by genetic polymorphisms.

Increases in the frequency of micronuclei (MN) in exposed cells can be used as a measure of genotoxicity. Hair dyes contain chemicals that are eliminated by urine and could be genotoxic to urothelial cells. To address this question, we evaluated whether hair dye use is associated with an increase in the frequency of MN in urothelial cells, and whether this association is modified by NAT1 (N-acetyltransferase 1), NAT2 (N-acetyltransferase 2) and GSTM1 (glutathione-S-transferase M1) genotypes. We included 92 women participating as controls in a bladder cancer case-control study in Spain. Of those, 72 had adequate number of cells to be included in the MN analysis. There were no significant differences in the mean MN frequency in women using hair dyes in the last month (9.88 MN/1000 cells), in comparison with the MN in unexposed women (9.50 MN/1000 cells). No statistically significant differences in MN frequency were observed by type of hair dye or color of the hair dye. Comparison of subjects in the highest quartile of MN frequency (> or = 12 MN/1000 cells) and those in the lowest quartile (< or = 4 MN/1000 cells) suggested an association between hair dye use and elevated MN frequency (OR 14.2 (95% CI 0.81-247.8; P=0.069)). None of the polymorphisms examined significantly modified association between hair dye use and frequency of MN. Findings of an increased frequency of MN in urothelial cells of hair dye users suggest a possible genotoxic effect of hair dye compounds and need confirmation in larger studies.

[Return to work after a non-work related sick spell: the role of age, sex, economic activity and autonomous community]. / Incapacidad temporal por contingencia común: papel de la edad, el sexo, la actividad económica y la comunidad autónoma.

BACKGROUND: To describe the duration of non-work related sickness absences incidents according to age, sex, economic activity and Autonomous Community. METHODS: The sample of non-work related sick spells included 76,598 incident cases started in 2002 among workers cover by the general regime of the Social Security system, and managed by an insurance company. The median and intercuartils range were estimated by sex, age, economic activities and Autonomous Comunnity. Probability ratio of continuing out of work (PRCOW) were compared among Autonomous Comunities, after adjusting by sexo, age and economic activities, taking Navarra as reference, using a log-logistic regression model with a gamma distribution. RESULTS: The 25% of cases there were returned to work at 40 day, the 50% at 90 day; and the 75% at 26 degrees day. Extremadura (PCOW=2,7; IC95%: 2,4-3,1) and Galicia (2,6; 2,4-2,9) showed the highest differences with Navarra. There were also statistically significant differences among economic activities after adjusting by age and sex. CONCLUSIONS: Return to work after a non-work related sick spell is a complex process, which is influenced by age, sex, economic activities and autonomous community.

Criteria and methods used for the assessment of fitness for work: a systematic review.

The main findings from reports published in scientific journals on the criteria and methods used to assess fitness for work were reviewed. Systematic searches were made using internet engine searches (1966-2005) with related keywords. 39 reports were identified, mostly from the US and western Europe. Assessment of fitness for work is defined by most as the evaluation of a worker's capacity to work without risk to their own or others' health and safety. It is mainly assessed at recruitment (pre-offer or post-offer), and when changes of work or health conditions occur. Five main criteria used by occupational doctors to evaluate fitness for work were identified: the determination of worker's capacity and worker's risk in relation to his or her workplace, as well as ethical, economic and legal criteria. Most authors agreed that assessment tools used need to be specific and cost-effective, and probably none gives unequivocal answers. Outcomes from fitness for work assessments range from "fit" to "unfit", with other possible intermediate categories such as "fit subject to work modifications", "fit with restrictions" or "conditionally fit (temporarily, permanently)". Workplace modifications to improve or adjust working conditions must always be considered. There is confusion about the decision-making process to be used to judge about fitness for work. There is very scarce scientific evidence based on empirical data, probably because there are no standard or valid methodologies for all professions and circumstances.
