Cost-Effectiveness of a Multi-faceted Workplace Intervention to Reduce Musculoskeletal Pain in Nursing Staff: A Cluster-Randomized Controlled Trial (INTEVAL_Spain).

PURPOSE: To evaluate the cost-effectiveness of a multifaceted workplace intervention to reduce musculoskeletal pain (MSP) in nursing staff. METHODS: The study was a 1-year cluster-randomized controlled trial. The intervention combined participatory ergonomics, health promotion, and case management. The control group received usual care. Societal and health system perspectives were used. Costs included direct health and indirect costs. The effects were MSP and quality-adjusted life years (QALYs). MSP was measured using the Standardized Nordic Questionnaire at baseline and 6- and 12-month follow-up. QALYs were measured using the EuroQol-5D-3L at 6- and 12-month follow-up. Incremental costs and QALYs were modelled using generalized linear models. MSP was analysed through generalized logistic models. Incremental cost-effectiveness ratios (ICERs) were calculated, and cost-effectiveness planes and acceptability curves were constructed. RESULTS: Total mean costs per person were €614 and €216 for the intervention and control group, respectively, with a societal perspective. The intervention mean cost was €38/person. From the societal perspective, the ICER showed that overall additional €68 (€9 from a health system perspective) were required to achieve 1-extra-percentage-point reduction of MSP. ICERs were €34 from the societal and €4 from the health system perspectives for neck, shoulders and upper back pain; €53 and €7 for low back; €179 and €23 for hands; €39 and €5 for legs; €115 and €14 for the knees; €36 and €5 for feet For MSP in the elbows. For participants with pain in the elbow, and for QALYs, the ICER showed that the intervention group was dominated by the control group. CONCLUSION: This intervention was not cost-effective in terms of QALYs. However, in terms of MSP, with a willingness to pay of €100, the probability of the intervention being cost-effective was around 90%. Further studies incorporating our recommendations are needed to confirm these findings. STUDY REGISTRATION: ISRCTN15780649, retrospectively registered.

Dealing with the unknown: perceptions, fears and worries of SARS-CoV-2 infection among hospital workers.

OBJECTIVE: This study explores fears and worries regarding SARS-CoV-2 risk of infection and transmission to relatives, co-workers, and patients in relation to non-pharmacological preventive interventions among healthcare workers (including physicians, nurses, aides, cleaners, maintenance, and security staff) in a healthcare institution in Barcelona (Spain), during the first and second waves of the SARS-CoV-2 pandemic. METHOD: The research used an explorative qualitative approach. Six focus groups and ten individual interviews were conducted online and audio-recorded, transcribed verbatim and analysed using thematic analysis and mixed coding. RESULTS: Forty professionals participated in the study. Four common themes emerged in all groups: challenges related to the lack of pandemic preparedness, concerns about personal protective equipment, unclear guidelines for case and contact tracing, and communication-related difficulties. CONCLUSIONS: This study emphasizes the key recommendations to improve non-pharmacological preventive interventions to reduce workers' fears and worries about the risk of infection and spreading the infection to others, including families. Above all, these should include ensuring the availability, and correct use of adequate personal protective equipment, improve guidelines on case and contact tracing, and setting effective communication channels for all workers of the organization. These recommendations must be reinforced in maintenance and security personnel, as well as night shift nurses and aides, to also reduce health inequalities.

[COVID-19: it's time for its full recognition as an occupational disease]. / COVID-19, es el momento de su reconocimiento pleno como enfermedad profesional.

In a context of transition towards the end of the pandemic, we think it is time to recognize COVID-19 as an occupational disease. The steps taken to recognize it as a work accident in health workers represent progress, but it is not enough. It is a step that the European Commission has recently recommended, including it on the European list of occupational diseases, in all those activities with a clear risk of contagious. This would imply objective advantages for workers and companies.

En un contexto de transición hacia el final de la pandemia, pensamos que es el momento o de reconocer como enfermedad profesional la COVID-19. Los pasos dados de reconocimiento como accidente de trabajo en sanitarios representan un avance, pero es insuficiente. Es un paso que ya ha recomendado recientemente la Comisión europea, para incluirla con el listado europeo de enfermedades profesionales, en todas aquellas actividades con un riesgo de infección demostrado. Esto supondría ventajas objetivas para las personas trabajadoras y las empresas.

Workplace aggression against healthcare workers in a Spanish healthcare institution between 2019 and 2021: The impact of the COVID-19 pandemic.

Objectives: Describe the incidence of first aggressions among healthcare workers (HCWs) before and during the COVID-19 pandemic in a Spanish healthcare institution, according to workers' socio-occupational characteristics and analyze the impact of the pandemic on it. Methods: A cohort involving HCWs who worked in the institution for at least 1 week each year from 1 January 2019 to 31 December 2021. Adjusted relative risks (aRR) were estimated using generalized estimating equations and negative binomial models to calculate the differences in WPA between the different time periods. All analyses were stratified by gender. Results: Among women, the incidence was 6.8% (6.0; 7.8) during the pre-COVID-19 period, 6.0% (5.2; 7.0) during the COVID-19 baseline and 5.1% (4.3; 5.9) during the COVID-19 endline; and 4.6% (3.4; 6.1), 5.3% (4.1; 6.8) and 4.4% (3.5; 5.8), respectively, among men. Among men, the incidence of WPA was 4.6 (3.4; 6.1), 5.3 (4.1; 6.8), and 4.4% (3.5; 5.8), respectively. These incidences were significantly higher among male nurses and aides [11.1 (8.0; 15.4), 12.3 (8.9; 16.6), and 9.3% (6.5; 13.3) during each period] and psychiatric center workers [women: 14.7 (11.2; 19.0), 15.4 (11.8; 19.8), and 12.4% (9.2; 16.6); men: 12.3 (7.2; 20.0), 17.8 (11.6; 26.2), and 14.3% (8.8; 22.4)]. Among women, the risk of WPA was 23% lower in the post-COVID-19 period compared to before the pandemic [aRR = 0.77 (0.64; 0.93)], while the risk during the COVID-19 baseline was not significantly different [aRR = 0.89 (0.74; 1.06)]. Conclusions: The COVID-19 pandemic led to an unexpected decrease in first-time WPA against HCWs. However, ~5% of HCWs experienced at least one incidence of aggression in the last follow-up year. Healthcare managers should continue to increase the prevention of aggression against HCWs, especially among vulnerable groups with a higher level of incidence.

Con este bagaje, comenzamos 2023, un año en el que nuestra revista cumple un cuarto de siglo llevando a cabo la misión para la que fue concebida, misión que los distintos comités editoriales que hemos participado consideramos un acierto: contribuir a la transferencia de conocimiento útil para avanzar en la mejora de la salud de las personas trabajadoras.

[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.

What Are the Dry Eye Questionnaires Available in the Scientific Literature Used for? A Scoping Review.

PURPOSE: Dry eye disease (DED) is a frequent chronic ophthalmic condition. Its diagnosis includes tests and patient reported outcomes (PRO) questionnaires. Although many PRO dry eye questionnaires (PRO-DEQs) are available, they differ greatly from each other and not all have been validated. The purpose of this study was to retrieve the PRO-DEQs present in the scientific literature by performing a descriptive analysis of them and identifying those with known validity and reliability characteristics and to perform a descriptive analysis of the geographic area, year of publication, and characteristics of the target population of the clinical studies that have used validated PRO-DEQs. DESIGN: Scoping review of the literature. METHODS: Searches were conducted in PubMed to retrieve PRO-DEQs published up to July 2018 and written in English, French, Italian or Spanish. RESULTS: One thousand six hundred two records were identified and 973 were included in the final analysis. Of these, 56 provided information on the design and validation of PRO-DEQs and 49 PRO-DEQs were identified. Twenty-two PRO-DEQs were validated (17 original and 5 modified) and 27 had no associated design, validity, and reliability studies. Most of the validated PRO-DEQs were designed in English, the number of items varies from 1 to 57, the dimensions are generally not specified, and they are self-administered. The greatest use of validated PRO-DEQs in clinical studies has been in Asia since 2010, with the Ocular Surface Disease Index being the most used. These questionnaires have been used mostly in adults, retired professionals, and people with visual diseases to diagnose DED. CONCLUSIONS: This study aims to encourage the use of validated PRO-DEQs to guarantee the quality of the results obtained and the comparability and replicability among studies.

Study of Excipients in Delayed Skin Reactions to mRNA Vaccines: Positive Delayed Intradermal Reactions to Polyethylene Glycol Provide New Insights for COVID-19 Arm.

BACKGROUND: Skin local reactions to mRNA COVID-19 vaccines have been linked to the use of vaccine excipients. The aim of the study is to evaluate the role of skin testing excipients in delayed skin reactions due to mRNA COVID-19 vaccines. METHODS: Skin testing among a group of healthcare workers with skin reactions due to mRNA vaccines was performed. Patch testing and intradermal testing (IDT) with polyethylene glycol (PEG)-400, PEG-2000, trometamol, and 1,2-dimyristoyl-sn-glycero-3-phosphocholine were performed. Healthcare workers without skin reactions to vaccines were used for skin testing as controls. RESULTS: Thirty-one healthcare workers (from a total of 4315 vaccinated healthcare workers) experienced cutaneous adverse vaccine reactions. Skin testing was performed in sixteen of the healthcare workers (11 delayed large local reactions (DLLR) and 5 widespread reactions). Positive IDT for PEG-2000 1% in DLLR was seen in 10 (90.9%) patients, in comparison with one (16.6%) individual with a delayed widespread reaction. Delayed positive IDT reactions for PEG-2000 1% on day 2 were observed in three (27.3%) patients with DLLR. Patch testing of the excipients was negative. Among 10 controls, only one exhibited a transient positive IDT reaction to PEG-2000 1%. CONCLUSIONS: Immediate and delayed reactions to IDT are frequently detected in patients with DLLR. The observation of positive delayed intradermal reactions to PEG disclosed only in patients with DLLR reinforces a possible role of PEG in the development of these reactions. Skin testing of other excipients is of little importance in clinical practice.

[Proposal for a summary index of the non-pharmacological preventive measures adopted against SARS-CoV-2 in companies, the case of Parc de Salut Mar (Barcelona).] / Propuesta de un índice que resume las medidas preventivas no farmacológicas adoptadas frente al SARS-CoV-2 en las empresas, el caso del Parc de Salut Mar (Barcelona).

INTRODUCTION: Construct a numerical index of non-pharmacological preventive measures against Sars-CoV-2 based on the experience of Parc de Salut Mar (PSMar), a healthcare institution in Barcelona. METHOD: The construction of the index was carried out in three phases. The identification and selection of the variables to be included based on semi-structured interviews with key informants and documental revision. The definition of the dimensions (consisting of one or more variables) and, finally, the operationalisation of the index on the basis of these dimensions. The index was estimated in the PSMar, and in its two main centres, the Hospital del Mar and the Hospital de la Esperanza. RESULTS: Twenty-one variables were identified and categorised into six dimensions: personal protective equipment, individual organisational measures, collective organisational measures, epidemiological surveillance measures, training activities and protocol development. During the first wave, the Hospital del Mar index remained above the value obtained at the Hospital de la Esperanza, while in the second wave both indexes showed similar values until week 36, when the Hospital del Mar index began to show higher values. These oscillations were mainly due to the dimensions of personal protective equipment and training activities. CONCLUSIONS: The proposed index shows the difficulties in implementing the various non-pharmacological preventive measures in the first weeks of the pandemic. This tool can be useful for evaluating the activities carried out by the Occupational Risk Prevention Services in the face of the pandemic, with the appropriate adaptations to the reality of each individual company.

Introducción: Construir un índice numérico con las medidas preventivas no farmacológicas frente a Sars-CoV-2 a partir de la experiencia del Parc de Salut Mar (PSMar), una institución sanitaria en Barcelona. Método: La construcción del índice se ha realizado en tres fases. La identificación y selección de las variables incluidas a partir de entrevistas semiestructuradas a informantes clave y la revisión documental. La definición de las dimensiones (con una o más variables) y la operacionalización del índice (a partir de las dimensiones). Se ha estimado el índice en el PSMar, y en sus dos principales centros, el Hospital del Mar y el Hospital de la Esperanza. Resultados: Se identificaron 21 variables, clasificadas en 6 dimensiones: equipos de protección individual, medidas organizativas individuales, medidas organizativas colectivas, medidas de vigilancia epidemiológica, actividades formativas, y elaboración de protocolos. Durante la primera ola, el índice en el Hospital del Mar se mantuvo por encima del valor obtenido en el Hospital de la Esperanza; en la segunda ola ambos índices presentaron valores similares hasta la semana 36, cuando el hospital del Mar comenzó a presentar valores superiores. Estas oscilaciones se debieron principalmente a los equipos de protección individual y actividades formativas. Conclusiones: El índice propuesto muestra las dificultades para aplicar las medidas preventivas no farmacológicas en las primeras semanas de la pandemia. Esta herramienta puede ser útil para evaluar las actividades desarrolladas frente a la pandemia por parte de los Servicios de Prevención de Riesgos Laborales, con las oportunas adaptaciones a la realidad de cada empresa.

Non-Pharmacological Preventive Measures Had an Impact on COVID-19 in Healthcare Workers before the Vaccination Effect: A Cohort Study.

Healthcare workers have been and still are at the forefront of COVID-19 patient care. Their infection had direct implications and caused important challenges for healthcare performance. The aim of this study is to assess the impact of non-pharmacological preventive measures against COVID-19 among healthcare workers. This study is based on a dynamic cohort of healthcare workers (n = 5543) who had been hired by a Spanish hospital for at least one week during 2020. Negative binomial regression models were used to estimate the incidence rate and the rate ratio (RR) between the two waves (defined from 15 March to 21 June and from 22 June to 31 December), considering natural immunity during the first wave and contextual variables. All models were stratified by socio-occupational variables. The average COVID-19 incidence rate per 1000 worker-days showed a significant reduction between the two waves, dropping from 0.82 (CI95%: 0.73-0.91) to 0.39 (0.35-0.44). The adjusted RR was 0.54 (0.48-0.87) when natural immunity was acquired during the first wave, and contextual variables were considered. The significant reduction of the COVID-19 incidence rate could be explained mainly by improvement in the non-pharmacological preventive interventions. It is needed to identify which measures were more effective. Young workers and those with a replacement contract were identified as vulnerable groups that need greater preventive efforts. Future preparedness plans would benefit from these results.

Al igual que ya sucedió en 2020, 2021 ha estado dominado por la pandemia de COVID-19. Si hace un año escribíamos esta Nota Editorial con gran preocupación por la evolución de la situación de la infección originada por el SARS-CoV-2 y, a su vez, con grandes esperanzas puestas en las vacunas como estrategia preventiva, la actual viene marcada por la incertidumbre generada por la irrupción de la nueva variante de preocupación: Omicrón….

[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.

What is meant by case management for the return-to-work of workers with musculoskeletal disorders? A scoping review.

BACKGROUND: Case management interventions have shown to be effective to prevent musculoskeletal pain and disability, but a single definition has not been achieved, nor an agreed profile for case managers. OBJECTIVE: To describe the elements that define case management and case managers tasks for return-to-work of workers with musculoskeletal disorders (MSDs). METHODS: A comprehensive computerized search of articles published in English until February 16, 2021 was carried out in several bibliographic databases. Grey literature was obtained through a search of 13 key websites. A peer-review screening of titles and abstracts was carried out. Full text in-depth analysis of the selected articles was performed for data extraction and synthesis of results. RESULTS: We identified 2,422 documents. After full-text screening 31 documents were included for analysis. These were mostly European and North American and had an experimental design. Fifteen documents were published between 2010 to 2021 and of these 7 studies were published from 2015. Fifteen elements were identified being the commonest "return-to-work programme" (44.4%) and "multidisciplinary assessment/interdisciplinary intervention" (44.4%). Of 18 tasks found, the most frequent was "establishing goals and planning return-to-work rehabilitation" (57.7%). Eighteen referral services were identified. CONCLUSIONS: Despite there were several elements frequently reported, some elements with scientific evidence of their importance to deal with MSDs (e.g. early return-to-work) were almost not mentioned. This study proposes key points for the description of case management and case managers tasks.

Process evaluation of a complex workplace intervention to prevent musculoskeletal pain in nursing staff: results from INTEVAL_Spain.

BACKGROUND: INTEVAL_Spain was a complex workplace intervention to prevent and manage musculoskeletal pain among nursing staff. Process evaluations can be especially useful for complex and multifaceted interventions through identifying the success or failure factors of an intervention to improve the intervention implementation. OBJECTIVES: This study performed a process evaluation of INTEVAL_Spain and aimed to examine whether the intervention was conducted according to the protocol, to investigate the fulfilment of expectations and the satisfaction of workers. METHODS: The intervention was a two-armed cluster randomized controlled trial and lasted 1 year. The process evaluation included quantitative and qualitative methods. Quantitative methods were used to address the indicators of Steckler and Linnan's framework. Data on recruitment was collected through a baseline questionnaire for the intervention and the control group. Reach and dose received were collected through participation sheets, dose delivered and fidelity through internal registries, and fulfilment of expectations and satisfaction were collected with two questions at 12-months follow-up. Qualitative methods were used for a content analysis of discussion groups at the end of the intervention led by an external moderator to explore satisfaction and recommendations. The general communication and activities were discussed, and final recommendations were agreed on. Data were synthesized and results were reported thematically. RESULTS: The study was performed in two Spanish hospitals during 2016-2017 and 257 workers participated. Recruitment was 62 and 51% for the intervention and the control group, respectively. The reach of the activities ranged from 96% for participatory ergonomics to 5% for healthy diet. The number of sessions offered ranged from 60 sessions for Nordic walking to one session for healthy diet. Fidelity of workers ranged from 100% for healthy diet and 79% for participatory ergonomics, to 42 and 39% for Nordic walking and case management, respectively. Lowest fidelity of providers was 75% for case management and 82% for Nordic walking. Fulfilment of expectations and satisfaction ranged from 6.6/10 and 7.6/10, respectively, for case management to 10/10 together for the healthy diet session. Discussion groups revealed several limitations for most of the activities, mainly focused on a lack of communication between the Champion (coordinator) and the workers. CONCLUSIONS: This process evaluation showed that the implementation of INTEVAL_Spain was predominantly carried out as intended. Process indicators differed depending on the activity. Several recommendations to improve the intervention implementation process are proposed. TRIAL REGISTRATION: ISRCTN15780649 .

The mRNA-1273 Vaccine Induces Cross-Variant Antibody Responses to SARS-CoV-2 With Distinct Profiles in Individuals With or Without Pre-Existing Immunity.

mRNA-based vaccines effectively induce protective neutralizing antibodies against SARS-CoV-2, the etiological agent of COVID-19. Yet, the kinetics and compositional patterns of vaccine-induced antibody responses to the original strain and emerging variants of concern remain largely unknown. Here we characterized serum antibody classes and subclasses targeting the spike receptor-binding domain of SARS-CoV-2 wild type and α, ß, γ and δ variants in a longitudinal cohort of SARS-CoV-2 naïve and COVID-19 recovered individuals receiving the mRNA-1273 vaccine. We found that mRNA-1273 vaccine recipients developed a SARS-CoV-2-specific antibody response with a subclass profile comparable to that induced by natural infection. Importantly, these antibody responses targeted both wild type SARS-CoV-2 as well as its α, ß, γ and δ variants. Following primary vaccination, individuals with pre-existing immunity showed higher induction of all antibodies but IgG3 compared to SARS-CoV-2-naïve subjects. Unlike naïve individuals, COVID-19 recovered subjects did not mount a recall antibody response upon the second vaccine dose. In these individuals, secondary immunization resulted in a slight reduction of IgG1 against the receptor-binding domain of ß and γ variants. Despite the lack of recall humoral response, vaccinees with pre-existing immunity still showed higher titers of IgG1 and IgA to all variants analyzed compared to fully vaccinated naïve individuals. Our findings indicate that mRNA-1273 vaccine triggered cross-variant antibody responses with distinct profiles in vaccinees with or without pre-existing immunity and suggest that individuals with prior history of SARS-CoV-2 infection may not benefit from the second mRNA vaccine dose with the current standard regimen.

Professional counseling in women with serious mental illness: achieving a shift toward a more effective contraceptive method.

OBJECTIVES: Mental disorders in reproductive-aged women have significant implications for the risk of unintended pregnancies. The objective of this study is to assess the professional counseling in clinical practice based on motivational interview in women with serious mental illness (SMI) in order to achieve a change to a more effective contraceptive method. STUDY DESIGN: A prospective observational cohort study (2012-2017) was conducted in a convenience sample of women with severe-moderate psychiatric disorders (n = 91). Information related to psychiatric health, contraceptive use, sexual and reproductive health and socio-demographics was collected. To assess the variation in the contraceptive method, follow-up visits were planned before and after medical counseling. All participants underwent an evidence-based individual motivational interview for contraception counseling. A multivariate logistic model was carried out to identify the factors involved in changing to a more effective contraceptive method. RESULTS: After evidence-based counseling, 51.6% of participants changed their contraceptive method to a more effective one. This change was associated with gender violence (ß coefficient = 1.58, p value = .006). The relation between changing to a more effective contraceptive method and both previous abortions and having children was also positive, although the coefficients did not reach statistical significance. CONCLUSIONS: Evidence-based contraception counseling in clinical practice, based on an adapted protocol to patients with SMI, has shown, in this study, to be adequate to promote the shift to more effective contraceptive methods, avoiding the need of daily compliance in this population. Gender violence has been significantly associated with the shift to very high effectiveness methods as well as previous abortions and having children, not significantly.

Validation of an Asbestos Exposure Questionnaire (QEAS-7) for Clinical Practice.

INTRODUCTION: The seven-item QEAS-7 questionnaire (exposure to asbestos questionnaire) has been designed as a useful and simple tool to establish the probability of exposure to asbestos. The objective of the present study is to validate the QEAS-7 following the recommended methodology. METHODS: The QEAS-7 was prospectively administered to 90 subjects with and without asbestos-related disease (ARD), on two consecutive occasions by two independent researchers. Logical and content validity was evaluated by a committee of experts and construct validity through hypothesis testing. Intra- and interobserver reliability was assessed by calculating Cohen's Kappa index (κ), which was estimated as weak if below 0.40, moderate if between 0.41 and 0.60 and good/very good if above 0.60. The comparison between proportions was examined using Pearson's Chi-square test. RESULTS: The majority of participants (88.9%) were male. Mean age was 70.8 years (SD = 8.4) and most of the sample had completed primary education but had not progressed further (62.2%). Forty-three had ARD. The logical, content and construct validity of the QEAS-7 was considered adequate both by a committee of experts and by the users interviewed. The mean administration time was 9 min and 25 s (SD = 3 min and 49 s). The verification of the five hypotheses confirmed the construct validity and the intra- and interobserver reliability to be κ = 0.93 and κ = 0.50 respectively. The concordance in the estimation of asbestos exposure was κ = 0.65. CONCLUSIONS: The QEAS-7 is a simple, valid and reliable tool for estimating the probability of exposure to asbestos. Its application in clinical practice appears justified. What is already known about this subject? No studies have been published to date on the validation of specific questionnaires designed to determine asbestos exposure for routine use by healthcare staff in the clinical setting. What are the new findings? This questionnaire can be considered a comprehensible, viable, valid and reliable instrument for identifying exposure to asbestos. Its brevity and simplicity of administration make it ideally suited for use in daily clinical practice. How might this impact on policy or clinical practice in the foreseeable future? This questionnaire can be of help for physicians attending to patients with suspected asbestos-related diseases both in the hospital and in the primary care setting.
