Fish and shellfish processing employs many thousands of people globally, with shellfish processing becoming more important in recent years. Shellfish processing is associated with multiple occupational health and safety (OHS) risks. Snow crab occupational asthma (OA) is work-related asthma associated with processing snow crab. We present a gender analysis of findings from a 3-year multifaceted study of snow crab OA in Newfoundland and Labrador, Canada. The study was carried out in four snow crab processing communities between 2001 and 2004. An anonymous survey questionnaire on knowledge, beliefs, and concerns related to processing snow crab administered to 158 workers attending community meetings at the start of the research found that women were significantly more likely than men to associate certain health problems, especially chest tightness, difficulty breathing, and cough, with crab processing (P<0.001). Worker health assessments carried out with 215 processing workers (187 current/28 former; 120 female/95 male) found that female participants were more likely to be diagnosed as almost certain/highly probable snow crab OA and allergy (P=0.001) and to be sensitized to snow crab (P=0.01) than male participants. Work histories from the health assessments were used to classify processing jobs as male or female. Allergen sampling (211 allergen samples: 115 area, 96 personal breathing zone) indicated that the plant areas where these male jobs were concentrated were associated with lower levels of aerosolized crab allergens (the agents responsible for OA to snow crab) than areas associated with female jobs. This difference was statistically significant in the two plants with poor ventilation (p<0.001 and P=0.017 for these plants). A gender analysis of work history data showed that female health assessment participants were likely to have worked longer processing snow crab than males (5 years versus 3.5 years, respectively). Cross-referencing of work history results with allergen sampling data for male and female job areas showed a gender difference in median cumulative exposures (duration of exposure x level of exposures) for health assessment participants. Health assessment participants with estimated higher median cumulative exposures were more likely to receive a diagnosis of almost certain/highly probable OA and allergy. Semistructured interviews with 27 health assessment participants (24 female/ 3 male) with a diagnosis of almost certain/highly probable or possible snow crab OA indicated that these workers can experience substantial quality of life impacts while working and that they seek to reduce the economic impact of their illness by remaining at their jobs as long as possible. Indications of selection bias and other study limitations point to the need for more research exploring the relationship between the gender division of labor and knowledge, beliefs, and concerns about snow crab processing, as well as gender differences in prevalence, quality of life, and socioeconomic impact.
OBJECTIVES: The aim of the study was to determine the prevalence of snow crab sensitisation and occupational asthma. STUDY DESIGN: Prevalence study of symptoms, pulmonary function testing and allergy testing to crab was conducted in four crab plants of different design in Newfoundland and Labrador, Canada. METHODS: Plants workers in four crab plants were interviewed and offered skin testing, RAST, pulmonary function testing and peak flow monitoring before and during crab processing. RESULTS: 38% (n=78) had atopy. 18% (n=39) had certain or highly probable crab asthma. The prevalence of sensitisation in different crab plants varied from 50% (n=19) to 15% (n=16) and the prevalence of certain or highly probable crab asthma varied from 50% (n=19) to 9% (n=3). CONCLUSION: Crab asthma and sensitisation to snow crab is a major health problem for snow crab plant workers in Newfoundland and Labrador.
OBJECTIVES: This study was conducted to learn from snow crab plants workers and others involved in the industry their knowledge and beliefs of health issues and potential solutions. STUDY DESIGN: This is a survey in four communities with different crab plant designs in Newfoundland and Labrador, Canada. METHODS: At the start of a meeting to discuss crab asthma participants were requested to complete the questionnaire. RESULTS: 65% of 196 participants believed there were health problems associated with crab plants. 85% have heard of crab asthma. Almost 80% identified correctly the major symptoms of crab asthma as difficulty breathing, chest tightness and cough. Only 74% of workers did not know that workers with crab asthma were eligible for workers' compensation. 55% of those surveyed had heard of crab asthma from crab plant workers and only 26% from their doctor or nurse. If they had breathing problems, 73% would see their local doctor, and 51% a specialist and 51% their nurse. CONCLUSION: The majority of participants believed that there were health problems associated with crab plants. The majority of crab plant workers could identify symptoms of crab asthma correctly. Many do not know that those with crab asthma can obtain workers' compensation. Most of them learn of crab asthma from other workers but would seek treatment from their doctor.
INTRODUCTION: There is a critical shortage of specialty rheumatology services in Canada. The impact is felt more in rural and northern regions than on urban areas of the country. In response to the need, this study was conducted to compare the satisfaction of referring physicians with rheumatology services through conventional visiting specialty clinics; email consults and regularly scheduled videoconference. METHODS: Three rural communities of similar size and availability of physician services were assigned to one of the following means of providing outreach rheumatology services: visiting rheumatologist clinics, email access to rheumatologist and scheduled videoconference consults. A case based pre/post test, and post satisfaction questionnaire were administered to the primary care physicians in these communities. Patient outcomes, and physician ability and confidence in managing specific arthritis problems, were measured. RESULTS: Physicians responded positively to all methods of rheumatology service provision. The videoconference group were the most positive. The reasons were: immediate feedback to referring physician and patient, effective case based learning and transfer of knowledge, and improved accessibility. CONCLUSION: Videoconference is preferred to visiting clinics and email as a method for rheumatology services to rural/northern communities. It is cost effective and there is knowledge transfer between the rheumatologist and the referring physicians.
INTRODUCTION: Telehealth in remote communities has been reported to be cost-effective for emergency medicine and possibly for psychiatry. METHODS: The cost of sending a patient out of a remote community for suicide assessment was compared with the cost of maintenance and on-line charges of videoconference. The cost comparison was used to determine the potential savings to the provincial government. User satisfaction was assessed through qualitative questionnaires. RESULTS: The use of videoconferencing for mental health assessment for 71 patients in a remote northern community saved the Government of Newfoundland and Labrador dollar 140,088 in 2003. Patients and health professionals were satisfied with mental health assessment via videoconference. CONCLUSION: The provision of mental health assessments for patients in a remote community in Labrador, Canada by videoconference was effective and saved money.
