Occupational science is a new scientific discipline that is defined as the systematic study of the human as an occupational being. A doctoral program in occupational science has been established at the University of Southern California, Los Angeles. With its emphasis on the provision of a multidimensional description of the substrates, form, function, meaning, and sociocultural and historical contexts of occupation, occupational science emphasizes the ability of humans throughout the life span to actively pursue and orchestrate occupations. In this paper, occupational science is described, defined, and distinguished from other social sciences. A general systems model is presented as a heuristic to explain occupation and organize knowledge in occupational science. The development of occupational science offers several key benefits to the profession of occupational therapy, including (a) fulfillment of the demand for doctoral-level faculty members in colleges and universities; (b) the generation of needed basic science research; and (c) the justification for and potential enhancement of practice.
The authors analyzed notified occupational diseases at the department of occupational diseases during the 10 past years, focusing attention on workers in the health workers' union. The highest ratio is that of viral hepatitis (64.8%) and skin diseases (14.7%). These are followed by other infectious diseases, tuberculosis, asthma bronchiale, etc. The largest number of occupational diseases was reported in female health workers (74.7%) which is consistent with nationwide data on occupational diseases. The high ratio of women is not surprising with regard to the marked feminization of this occupation. The highest ratio of occupational diseases was reported in women aged 21-30 years, whereby viral hepatitis accounted for 32.6%. Occupational diseases are important not only from the medical but also from the economic aspect. Therefore even a minor reduction of occupational diseases has marked economic consequences. From the investigation ensues that at present it is important to concentrate above all on two groups of occupational diseases, i.e. occupational infectious contagious diseases and occupational skin diseases. A prerequisite for reduction of type B viral hepatitis is immunization of health workers at risk departments against hepatitis B, which is being implemented at present.
University of Occupational and Environmental Health (UOEH) conducts three courses in postgraduate education of occupational health (OH). Graduates of UOEH who have already received a basic education in OH can participate in any course and are trained to play an appropriate role as an occupational physician (OP). We operate the training program to provide practical knowledge and skills as well as to encourage interest in occupational health and to promote a further understanding of the role of the OP. In this study we evaluated changes in attitude of participants and the effectiveness of our program by an anonymous questionnaire. The subjects were all 19 participants of the 3-month program conducted between September 2003 and February 2004 as a part of the postgraduate education following several years of clinical experience. They were expected to be occupational physicians with a clinical specialty. The data were collected from questionnaires handed out at the beginning and the end of the program. The questionnaire included 8 items on the attitude toward occupational health. The subjects answered the questions according to a scale of 1 to 7. Data analysis was performed using the unpaired t-test by SPSS. The results suggested that our training program had a positive effect on trainees. Interest in occupational practice (P < 0.05) and willingness to act as a full-time occupational physician in a large company (P < 0.05) increased significantly. When considering the positive correlation between willingness to act as an OP and interest in a field that has some overlap between the speciality and occupational health, it was thought that developing a vision as an OP with respect to their career was important for training. However, in some clinical fields it may be difficult to define a relationship between the clinical speciality and occupational health. Understanding the role of an OP (P < 0.05) and self-confidence in playing an appropriate role as an OP (P < 0.05) also showed significant improvement. On the other hand, fourteen of the trainees (74%) did not have enough confidence to play a role as an OP even after completion of the program. In this study, the questionnaire we used was anonymous and did not include items concerning various attributes of the subjects. Therefore it was not possible to analyze changes of attitude at the individual level. We recognize the need to improve the program and are preparing a new version of the educational program with emphasis on understanding company organization activities and practical skills for problem solving. Opportunities to consider association between clinical speciality and occupational health are also included in this new version. We hope that the new program will further encourage trainees.
A number of studies carried out in different countries have shown that farmers have a low morbidity and mortality in comparison to those in other occupations. However, this has been questioned on the basis that some type of selective process may be operating, in that persons having health problems will avoid farming, or are forced to leave farming for other occupations. To determine the occurrence of a so-called 'healthy worker effect', this postal survey of 'elimination' from farming and farming-associated occupations has been carried out. A total of 1283 male farmers and 334 male farm workers born in 1935 and active in Sweden in 1970 were taken as the study group. As controls, a similar number of occupationally active men of the same age and living in the same municipalities were randomly chosen. The results showed that farmers changed occupation or retired early less often than those in other occupations did, whereas more farm workers changed occupation and retired than did other workers of the same age. Among the different reasons given for work change/retirement, low income/poor earning capacity was more common among the farmers and farm workers than among the controls. Illness was less common among farmers but tended to be more common among farm workers as cause of work change. Few farmers changed their occupation because they were offered other work, in comparison to those in other occupations. Allergic disease more often led to an occupation change among farmers, while they less often gave cardiac disease and locomotor problems as a reason for change of occupation, this was probably also true for the farm workers.(ABSTRACT TRUNCATED AT 250 WORDS)
Few data are available about the prevalence of occupational exposures to agents which can cause occupational asthma or aggravate preexisting asthma (asthmogens). Using potential occupational exposure data from the National Occupational Exposure Survey (NOES) of 1980-1983, we investigated the number of asthmogen exposures, asthmogen-exposure(s) per production worker, and unprotected occupational asthmogen exposures in different industries and occupations. Data for the entire United States were used to generate estimates of occupational exposure at two selected state and local levels. It was estimated that 7,864,000 workers in the surveyed industries were potentially exposed to one or more occupational asthmogen(s) in the United States. The average number of observed potential exposures per asthmogen-exposed worker was 4.4, and varied from 11.9, in the Water Transportation industry, to 1.2 in Local and Suburban transportation. The largest number of observed potential exposures was recorded in the Apparel and Other Finished Products (garment) industry. This work and further analyses using this approach are expected to contribute to a better understanding of the epidemiology of occupational asthma, and to serve as a guide to target future occupational asthma surveillance efforts.
A review of the many attempts to establish an association between occupations and alcoholism reveals that most do not deal with data about clinically defined alcoholism but instead use data about cirrhosis mortality, self-reported alcohol problems, and frequent and heavy drinking. The present study establishes an association between occupations and diagnoses of Alcohol Dependence Disorder and Alcohol Abuse Disorder, using data from a large population-based household interview study. Statistical adjustment using logistic methods reveals that apparent associations between occupations and alcohol-related disorders previously reported in the literature are due to characteristics of those employed in various occupations. The prevalence of alcohol dependence and abuse in two high risk industries, construction and transportation, is confirmed. More than one in four construction laborers and one in five skilled construction trades workers received a DIS/DSM-III diagnosis related to alcohol abuse. In the transportation industry one in six heavy truck drivers and material movers received an alcohol diagnosis. Analyses of the data from individuals currently employed and not employed in their occupation reveals reduction in risk for those who leave some occupations and increased risk for those who leave other occupations. Evidence is presented that employment in some occupations may be protective for Alcohol Dependence. The findings support the view that occupation may be associated with Alcohol Dependence and Alcohol Abuse independent of demographic variations. Previously proposed explanatory models for associations between occupations and alcohol problems are called into question because they do not take into account the demographic characteristics and employment status of workers.
BACKGROUND: The paper is based on a keynote address delivered at the 2004 CAOT Conference in Charlottetown, Prince Edward Island Occupational therapists are widely associated with a medical model of health care in which recognition of how engagement in occupation contributes to health status is poorly understood. Occupational science as the study of people as occupational beings has the potential to increase such understanding. PURPOSE: This paper considers some aspects of the relationship between health and the occupations of older people to highlight avenues for change and the research required to support them. METHOD: The paper is structured around a simple verse of dialogue between a healthy old man and an occupational therapist. Explanation of the dialogue draws upon historical and current literature as well as occupational science research to provide a rationale for future practice based on broader concepts of occupation for health. RESULTS AND PRACTICE SUGGESTIONS: The dialogue promotes the need for discussion about health and about the health notion of Active Ageing. It highlights professional language as one impediment to change and suggests that research concerning occupation as it relates to population health is a primary requirement for the future of occupational therapy.
Most spinal cord injuries (SCIs) are the result of motor vehicle accidents (MVAs). There are no published reports specifically addressing SCIs that occur in the workplace. We report a cohort survey study examining the frequency and etiology of SCI in the workplace. Through a cooperative program, an evaluation of all SCIs seen in Colorado during a 5 1/2-year period (January 1, 1986 through June 6, 1991) is presented. We report a detailed analysis of specific data of all SCIs occurring in the workplace. There were a total of 566, with 74 (13.1%) due to injuries that occurred during the course of employment. The most common cause of occupational SCI was falls, which occurred in 37 (50%), as compared with only 15.9% of non-occupational SCIs. Only 14 (18.9%) occupational SCIs resulted from MVAs, compared with 59.3% of non-occupational SCIs. Other major etiologies for occupational SCI included being hit by a falling object in 14 individuals (18.9%), gunshot wound in three (4%), skiing in one (1.4%), stabbing in one (1.4%), and other causes in four (5.4%). Construction occupations were over-represented in occupational SCIs with 41.9% of cases as compared with only 6.3% for the non-occupational group. Because of the large percentage of occupational SCIs, efforts should be aimed at educating workers in at-risk occupations to prevent this serious injury.
BACKGROUND: About 15% of lung cancers (LC) might be attributable to occupation. However, clinical practice shows that LC percentage for which occupational aetiology is recognized is lower than expected. OBJECTIVES: To address the role of Occupational Physicians (OP) in systematic search and aetiological diagnosis of LC. METHODS: The search was carried out at a university hospital in Brescia, northern Italy, a highly industrialized area with many workers potentially exposed to occupational lung carcinogens. Through short occupational history forms, physicians of various departments refer all new cases of primary LC to OP When occupational exposure to lung carcinogens is presumed, the OP evaluates the case at the occupational health clinic and sends clinical reports to notifying physicians, containing aetiological diagnosis and indications for medico-legal obligations. RESULTS: Before 1998, few cases were referred to the OP and even less were compensated. The search yielded 1502 LC; after screening, full occupational health evaluation was performed in 693 cases: occupational aetiology was recognized in 182 (26%). Risk factors were silica, asbestos, polycyclic aromatic hydrocarbons, truck driving, painting, road paving; many workers were exposed to multiple carcinogens. 48 cases were compensated, many others are under litigation. CONCLUSIONS: A systematic LC search made it possible to: reach an aetiological diagnosis and reduce the gap between expected LC and those reported/compensated; inform health authorities and undertake preventive action in workplaces; detect sentinel events; provide epidemiological data at community level; promote cooperation among health professionals (oncologists, surgeons, pneumologists, general practitioners, plant OP); increase teaching opportunities for medical students, those taking a specialisation course in occupational health; provide counselling and expert opinions for individual subjects, trade unions, employers, law courts.
BACKGROUND: Infectious diseases remain an important cause of self-reported work-related illness, with socio-economic consequences, including sickness absence. Reporting of infectious disease by occupational and specialist physicians is an important tool in the investigation of occupationally related infections and is relevant in their management. AIMS: To examine the reporting of cases of infectious disease by occupational and specialist physicians to schemes collecting data on occupational ill-health. METHODS: Cases of infectious disease reported by occupational and specialist physicians to the UK based schemes, Occupational Disease Intelligence Network (ODIN) and The Health and Occupation Reporting network (THOR), from 2000 to 2003 were analysed by reporting patterns, diagnosis, single case or outbreak reporting and industry. RESULTS: The total number of estimated cases of infectious disease reported to ODIN and THOR from 2000 to 2003 was 5606; 74.9% cases were diarrhoeal disease, and 11.1% scabies. The majority (81.4%) of cases were reported in SIDAW, where the participation rate for reporters was 55%. Reporting rates were much higher in OPRA, SWORD and EPIDERM (ranging from 86 to 96%). The most frequently reported industrial sectors were social care (39.5%) and health (29.4%); while the manufacture of chemical products contributed 4.3% overall, but 33.8% to estimated cases in OPRA. CONCLUSIONS: Despite limitations related to under reporting, the occupational and specialist physician schemes in ODIN and THOR provide data that may be used to look at patterns of case reporting for occupational ill-health, including infectious disease. The reporting schemes also provide an important means of alerting peers about potential novel causes, precipitating factors, or industrial sectors associated with occupational disease.
An important challenge to occupational health services in Japan is the necessary shift from regulation-based occupational health program to health risk-based program. The Occupational Safety and Health Management System (OSHMS) is an effective tool for introducing risk-based activities. To date, the Five Management system has been used to manage occupational health activities. This classification, however, does not show the interactions among the listed activities. Nor is it clear how this system contributes to the PDCA (Plan/Do/Check/Act) cycle for continual improvement. The category in the Five Management system called "Roles of the Occupational Physician" covers most of the occupational health services required in Japan. The items listed in the Five Management system were compared to the guidelines of OSHMS from the International Labour Office and issues that should be solved for occupational health activities with OSHMS were clarified. Seven issues are discussed in this paper; (1) occupational safety and health policy and audit that can drive the PDCA cycle effectively, (2) reclassification of occupational health activities with several different objectives, (3) set up of targets, (4) risk assessment methods that can prioritize health risks compared to safety risks, (5) exposure assessment methods for risk assessment, (6) flexibility of laws and regulations, and (7) development of talented professionals for risk-based occupational health activities.
This article examines how sexual orientation may be relevant to the study of occupations and the practice of occupational therapy. It is suggested that a lesbian, gay, or bisexual orientation may influence the occupations in which a person engages, the symbolic interpretation of those occupations, and the environmental contingencies of those occupations, and thus is an appropriate topic for occupational scientists to address. With the use of clinical reasoning studies and literature on authentic occupational therapy, it is argued that a person's lesbian, gay, or bisexual orientation may be relevant to the therapeutic process if therapists are to truly achieve an intersubjective understanding of the patient's world and create an environment in which the patient is able to live a meaningful life. Given this argument as a foundation, the article explores why sexual orientation may be overlooked in some of the theoretical perspectives that guide practice. The narrative perspective on identity is introduced as one potentially valuable way that occupational therapy researchers and practitioners may understand sexual orientation and its relationship to occupation. Specifically it is suggested that sexual orientation may be understood, in part, as a symbolic theme of meaning that informs values and convictions that may then be expressed in one's choice of occupations.
Changes in the health system require occupational therapy practitioners to focus their concerns on the long-term health needs of people and to help them develop healthy behaviors not only to improve their health, but also to minimize the health care costs associated with dysfunction. Occupational therapy practitioners must initiate efforts in the community to integrate a range of services that promote, protect, and improve the health of the public. This article shares the experiences of Canadian occupational therapy practitioners, who were challenged by their government nearly 15 years ago to establish a system that demonstrates effectiveness by improving the health of occupational therapy clients. By focusing on occupational performance, occupational therapy practitioners assist clients in becoming actively engaged in their life activities. This requires client-centered and family-centered practice and services that span from the agency or institution to the community. Occupational therapy practitioners must work collaboratively with persons in the client's environment (e.g., family members, teachers, independent living specialists, employers, neighbors, friends) to assist the client in obtaining skills and to make modifications to remove barriers that create a social disadvantage. A focus on occupational performance requires occupational therapy personnel to reframe how we think about occupational therapy to a sociomedical context and to take an active role in building healthy communities.
In order to determine key competences required of occupational medicine specialists, common throughout Europe, a questionnaire has been developed and distributed among several European countries. The questionnaire contained 115 subjects related to 8 fields of activities carried out by occupational medicine physicians (occupational hazards to health, assessment of disability and fitness for work, communications, research methods, management, environmental medicine, occupational health law and ethics, and health promotion). In each of these fields, competences were classified into three following categories: knowledge, experience and skills. Respondents were asked to allocate a score from 0 to 5 for each subject, where 0 = not necessary; 1 = of minimum importance, and 5 = most important or essential. In Poland the questionnaire was distributed among two groups of specialists: group I--experienced specialists in occupational medicine (leading representatives of occupational health care management), and group II--relatively younger and less experienced occupational medicine physicians, participating in the specialist training, organised by The Nofer Institute of Occupational Medicine. A comprehensive analysis of the completed questionnaires was carried out in two dimensions: substantive (the importance of individual competences as perceived by Polish specialists in occupational medicine), and comparative (evaluation and interpretation of similarities and differences between two groups of respondents). A hierarchy of requirements, occupational medicine training in Poland is to satisfy, was reconstructed with two sets of competences, one recognised by respondents as needless and the other recognised as useful with different grades of importance. Some characteristic differences in opinions between two groups studies were highlighted.
As industries' structures have evolved and diversified recently, the framework of occupational health nursing has been expanded on multidisciplinary bases. On the occasion of the opening of the School of Health Sciences, University of Occupational and Environmental Health, Japan (UOEH), the author was given an opportunity to visit US administrations, academic institutions and some industries to investigate occupational medicine and health nursing in that country. And as the author took part in programming the 17th UOEH International Symposium on Occupational Health Nursing Expertise that took place at the campus of the University in October, 1997, these two events are reported in this paper. The first part of the report is on the visit to the US occupational health professionals including occupational health doctors, nurses, industrial hygienists and other staffs. They have perceived that there has never been more emphasis placed on the significance of occupational health services than in recent years, and that young students have become more interested in occupational health. The second report will be on the 17th UOEH International Symposium--Occupational Health Nursing Expertise--the next time.
