The CUPID (Cultural and Psychosocial Influences on Disability) study: methods of data collection and characteristics of study sample

Background

The CUPID (Cultural and Psychosocial Influences on Disability) study was established to explore the hypothesis that common musculoskeletal disorders (MSDs) and associated disability are importantly influenced by culturally determined health beliefs and expectations. This paper describes the methods of data collection and various characteristics of the study sample.

Methods/Principal Findings

A standardised questionnaire covering musculoskeletal symptoms, disability and potential risk factors, was used to collect information from 47 samples of nurses, office workers, and other (mostly manual) workers in 18 countries from six continents. In addition, local investigators provided data on economic aspects of employment for each occupational group. Participation exceeded 80% in 33 of the 47 occupational groups, and after pre-specified exclusions, analysis was based on 12,426 subjects (92 to 1018 per occupational group). As expected, there was high usage of computer keyboards by office workers, while nurses had the highest prevalence of heavy manual lifting in all but one country. There was substantial heterogeneity between occupational groups in economic and psychosocial aspects of work; three- to five-fold variation in awareness of someone outside work with musculoskeletal pain; and more than ten-fold variation in the prevalence of adverse health beliefs about back and arm pain, and in awareness of terms such as “repetitive strain injury” (RSI).

Conclusions/Significance

The large differences in psychosocial risk factors (including knowledge and beliefs about MSDs) between occupational groups should allow the study hypothesis to be addressed effectively.     

Occupational health hazards resulting from elevated work rate situations.

Some occupational health hazards resulting from an elevated rate of work due to recent mechanization and automatization are discussed on the basis of results of health examinations. A rapid increase of a cervicobrachial disorder among young cash register and packing machine operators has been observed. Switching to the use of electronic cash registers has been shown to have only limited efficacy due to increased operation speed, and high-speed complex finger and hand movements of packer operators have also proven to be as hazardous as key-board operations. The high incidence of low-back pain, in particular gradually developing pain, among workers in electric power supply work has been suggested to be the result of quick and intensified work to meet increasing supply demand. Likewise, the workload of electric locomotive and bullet train drivers has increased in accordance with increased train speeds, and has been shown to have had significant effects on their health particularly in regards to neural strain, intra-cab environment such as air pressure change, vibration, and noise, and rotation on irregular shifts. New steps seem required therefore to meet the new health problems arising from a combination of modern technological changes and elevated working speeds.     

Risks faced by laboratory workers in the AIDS era.

Laboratory workers are at occupational risk of exposure to microrganisms that cause a wide variety of diseases, from inapparent to life-threatening ones. Principal routes of transmission include percutaneous and permucosal inoculation (comprising clinical inapparent cutaneous or mucosal exposure to blood or blood products), inhalation, and ingestion. The appearance of the Acquired Immunodeficiency Syndrome (AIDS) epidemic and the first reports of occupational Human Immunodeficiency Virus (HIV) infections in health care workers resulted in high anxiety among laboratory workers. Indeed, 21% of worldwide documented cases of occupational HIV infection occurred among laboratory workers. Research laboratories pose the highest risk of infection. Safe methods for managing infectious agents ("containment") in the laboratory setting include laboratory practice and technique, safety equipment, and facility design. Infection control in the laboratory setting should take into account adherence to guidelines (biosafety levels), education and training, and the development of safety products designed to reduce the risk of exposure.     

Establishing a culture of care, conscience, and responsibility: addressing the improvement of scientific discovery and animal welfare through science-based performance standards

Science-based performance standards offer a viable means of reducing regulatory burden while ensuring that research animal welfare and high-quality research data are realized. Unlike rigid regulations, science-based performance standards evolve as new information becomes available, thereby allowing new discoveries to be implemented in a timely manner and in a way that more effectively benefits the animals and the science. The implementation of performance standards requires a well-coordinated institutional team composed of the administration, research staff, the institutional animal care and use committee, professional and technical animal care personnel, occupational health and safety staff, and physical plant staff. This animal program team is best supported in an institutional environment that reflects a culture of care, compliance, and responsibility. In such a culture, the professional judgment exercised by the team is well grounded in meeting the diverse needs of the program's customers, who include the animals, the researchers, and research stakeholders such as the public. The institutional culture of care, compliance, and responsibility fosters workplace integrity, an ethics-based decision-making paradigm, sound understanding of institutional expectations through good communication and clear lines of authority, the hiring and retention of trained and well-qualified individuals, and a system for continuous development and improvement of the program.     

Industry calling! Is there a doctor in the house?

Medical service is needed in industry by both management and labor as never before. Industry is just beginning to awaken to this need. The medical profession is largely unaware of it. Unless physicians are prepared to heed this call, there is danger that management and labor will come to a bipartisan agreement over the bargaining table which will specify the amount, quality, and price of medical service irrespective of the effects of such an agreement on the practice of medicine. Such agreements should invariably be tripartite-between management, labor and medicine-if we are to continue to strive for medicine's traditional ideals: The best of medical care for all alike. This situation imposes at least two important obligations on organized medicine at the national level and especially at state and local levels where there is industrial concentration:1. Provision of a strong and competent committee or council whose members are especially interested in occupational medicine and who will make their presence known to management and labor alike, offering to advise with them on all medical problems, to mediate their disagreements or medical questions, and to help them attain a common goal.2. Assisting the members of organized medicine who are interested, to learn more about the medical problems peculiar to occupational health.     

Occupational health problems among migrant and seasonal farm workers.

Migrant and seasonal farm workers are one of the most underserved and understudied populations in the United States. The total US population of such farm workers has been estimated at 5 million, of whom about 20% live or work in California. Farm workers perform strenuous tasks and are exposed to a wide variety of occupational risks and hazards. Low socioeconomic status and poor access to health care also contribute to existing health problems in this population. Potential farm work-related health problems include accidents, pesticide-related illnesses, musculoskeletal and soft-tissue disorders, dermatitis, noninfectious respiratory conditions, reproductive health problems, health problems of children of farm workers, climate-caused illnesses, communicable diseases, bladder and kidney disorders, and eye and ear problems. Few epidemiologic studies exist of these occupational health problems. No comprehensive epidemiologic studies have assessed the magnitude of occupational health problems among migrant and seasonal farm workers and their dependents. Although the migratory nature of this population makes long-term studies difficult, the development of standardized data collection instruments for health consequences and scientific assessment of farm work exposures and working conditions are vital to characterize and reduce the occupational health risks in farm workers.     

Prospective study of clinical,laboratory, and ancillary staff with accidental exposures to blood or body fluids from patients infected with HIV.

In a prospective study of 150 health care workers in the United Kingdom who had been accidentally exposed to the human immunodeficiency virus no evidence of transmission was found. Larger studies in the United States and anecdotal accounts in publications from other countries confirm that the risk of occupational infection is very low. Health care workers must adopt safe procedures at all times, however, to avoid exposure to infection.

DISASTER MEDICAL CARE AND SHELTER-The Federal Program

The role of the physician in event of natural disaster or overwhelming (perhaps nuclear) attack by an enemy is:To assist the layman in preparing to meet his own health needs in a disaster situation until organized health services can reach him. To prepare and plan for the provision of organized medical care when conditions permit. To extend his own capability to render medical care outside his normal specialty. To assist in the training of allied and professional health workers and laymen for specific mobilization assignments in health services.

Effect of cotton dust on lungs among female workers in cotton industry in northern Gujarat,India

Byssinosis is a disabling occupational lung disease caused by cotton dust. It is a well-known occupational respiratory disease in cotton industry workers caused by cotton dust pollution. Many studies have been documented the effects of cotton dust on pulmonary function among workers employed in cotton-spinning mills. However, little data exist on the prevalence of this disorder in female workers particularly in western part of India. The present study was conducted to analyze the effects of exposure to cotton dust on pulmonary functions among female workers. The study was designed to assess the effects of exposure to cotton dust on lung functions among female cotton industry workers. Study group comprises 50 Female workers of cotton industry and control group comprises 50 age matched females who were neither worked in cotton industry nor exposed to cotton dust. Information was collected using standardized questionnaires, physical examination and spirometric measurements. Student''s T test was used to find the difference between spirometric parameters. All the respiratory parameters (FVC, FEV1, FEV1/FVC ratio, FEF 25-75 % PEFR and MVV) were reduced in cotton industry workers as compared with control subjects (p<0.0001) and no significant difference of SpO2 between groups. Cotton dust exposure makes huge impact on respiratory parameters of the cotton industry workers. This deterioration in respiratory health deteriorates with increasing duration of exposure. The health hazards caused by cotton dust should be controlled by creating awareness among the workers & employers.     

How primary health care professionals and residents assess issues related to the oral health of older persons?

doi: 10.1111/j.1741‐2358.2009.00355.x
How primary health care professionals and residents assess issues related to the oral health of older persons? Background and objectives: It is known that older persons need integrated primary health care. However, oral health may not be a frequent concern of multi‐professional teams taking care of older persons. The aim of the present study was to evaluate knowledge and practices related to oral health care, as reported by professionals and residents in a primary health care service. Material and methods: One hundred and seventy‐three health professionals and residents were assessed in this cross‐sectional study by means of a structured questionnaire containing questions pertaining to oral health practices and beliefs. Participants were grouped based on their professions into “primary health care dentists” or “other primary health care professionals” and based on their working status into “permanent team” or “residents”. Results: Permanent team members (other professionals) assessed and recommended dental care more frequently than residents. Permanent team members (other professionals) also reported that they felt they were able to inform older patients in respect to oral health‐related issues more frequently than did residents (68.7% vs. 31.3%, respectively). Conclusion: Oral health‐related knowledge and beliefs were frequent among non‐dentists primary health care workers, suggesting that primary health care which integrates oral health represents an attainable goal.     

Stress and health Huangshan-style

The Seventh International Congress of the Cell Stress Society International (CSSI) was held as a joint meeting with the newly organized committee of Stress Physiology, the Chinese Association for Physiological Sciences (CAPS). There were over 200 colleagues and their students in attendance from 22 different countries. The topics of the congress were core scientific areas in the field of stress and health. The keynote speakers were Fu-Chu He (China), E.R. (Ron) de Kloet (The Netherlands), and Kazuhiro Nagata (Japan). The CSSI Medallion for Career Achievement in the cell stress and chaperones field was awarded to Kazutoshi Mori (Japan). Twelve student post awards were given in recognition of a very high quality poster session. In the tradition of this series of congresses, cultural events were an important part of the program. In addition, participants became better acquainted during trips to the ancient shopping street, an evening at the Chinese opera, and a lesson in Tai Chi from a master. The first groups of CSSI Fellows and Senior Fellows were presented their rosettes and certificates during the congress.     

An Ecological Perspective on Medical Care: Environmental, Occupational, and Public Health Impacts of Medical Supply and Pharmaceutical Chains

Healthcare organizations are increasingly examining the impacts of their facilities and operations on the natural environment, their workers, and the broader community, but the ecological impacts of specific healthcare services provided within these institutions have not been assessed. This paper provides a qualitative assessment of healthcare practices that takes into account the life-cycle impacts of a variety of materials used in typical medical care. We conducted an ethnographic study of three medical inpatient units: a conventional cancer ward, palliative care unit, and a hospice center. Participant observations (73 participants) of healthcare and support staff including physicians, nurses, housekeepers, and administrators were made to inventory materials and document practices used in patient care. Semi-structured interviews provided insight into common practices. We identified three major domains that highlight the cumulative environmental, occupational health, and public health impacts of medical supplies and pharmaceuticals used at our research sites: (1) medical supply procurement; (2) generation, handling, and disposal of medical waste; and (3) pharmaceutical handling and disposal. Impacts discovered through ethnographic inquiry included occupational exposures to chemotherapy and infectious waste, and public health exposures to pharmaceutical waste. This study provides new insight into the environmental, occupational, and public health impacts resulting from medical practices. In many cases, the lack of clear guidance and regulations regarding environmental impacts contributed to elevated harms to the natural environment, workers, and the broader community.     

Modification of interleukin-15 serum levels in workers exposed to chemotherapeutic agents

Cytostatic anticancer drugs are known as carcinogenic, mutagenic, and teratogenic risk factors for health care workers occupationally exposed. It has been demonstrated that the administration of interleukin-15 in rat models of colon carcinoma protects against chemotherapy-induced gastrointestinal toxicities. We found that occupational exposure to chemotherapeutic antiblastic agents in vivo modified circulating levels of interleukin-15 in 17 health care workers exposed to antineoplastic drugs in relation to their jobs and in as many healthy age- and sex-matched subjects. Health care workers displayed significantly higher circulating interleukin-15 levels compared to their age-matched controls. If this increase representing an anticancer response remains to be established, these findings strengthen the idea of a therapeutic use of interleukin-15 in the field of cancer.     

Health hazard among cash register operators and the effect of improved working conditions.

The health condition of female cash register operators in relation to their working conditions was investigated. A questionnaire study revealed that cash register operators more frequently complained of general fatigue, headache, sleeplessness, and low back pain than female office machine operators or other female workers. Dullness and pain in the shoulder, arm, hand, and fingers especially on the right side were characteristic of cash register operators. Physical examinations in 1973 showed that 31.3% of 371 cash register operators suffered from muscle rigidity or tenderness; 13 were severely afficted and, 69 operators had to be either laid off, reassigned to other jobs, or given shorter working hours. Occupational cervicobrachial disorders were suggested to have been caused by repetitive upper limb motions combined with static load, an unfavorable working environment, and mental stress. Implementation of some improvements including shorter operation time, worker rotation, and adoption of electronic registers proved effective in reducing the number of sufferers of cervicobrachial disorders found during the 1975 physical examinations. But the improvements were not effective enough to alleviate fatigue of the neck, shoulder, and back due presumably to sustaining upper limbs while operating the keyboard.     

Performance bonuses and the quality of primary health care delivered by family health teams in Brazil: A difference-in-differences analysis

BackgroundPay-for-performance (P4P) programmes to incentivise health providers to improve quality of care have been widely implemented globally. Despite intuitive appeal, evidence on the effectiveness of P4P is mixed, potentially due to differences in how schemes are designed. We exploited municipality variation in the design features of Brazil’s National Programme for Improving Primary Care Access and Quality (PMAQ) to examine whether performance bonuses given to family health team workers were associated with changes in the quality of care and whether the size of bonus mattered.Methods and findingsFor this quasi-experimental study, we used a difference-in-differences approach combined with matching. We compared changes over time in the quality of care delivered by family health teams between (bonus) municipalities that chose to use some or all of the PMAQ money to provide performance-related bonuses to team workers with (nonbonus) municipalities that invested the funds using traditional input-based budgets. The primary outcome was the PMAQ score, a quality of care index on a scale of 0 to 100, based on several hundred indicators (ranging from 598 to 660) of health care delivery. We did one-to-one matching of bonus municipalities to nonbonus municipalities based on baseline demographic and economic characteristics. On the matched sample, we used ordinary least squares regression to estimate the association of any bonus and size of bonus with the prepost change over time (between November 2011 and October 2015) in the PMAQ score. We performed subgroup analyses with respect to the local area income of the family health team. The matched analytical sample comprised 2,346 municipalities (1,173 nonbonus municipalities; 1,173 bonus municipalities), containing 10,275 family health teams that participated in PMAQ from the outset. Bonus municipalities were associated with a 4.6 (95% CI: 2.7 to 6.4; p < 0.001) percentage point increase in the PMAQ score compared with nonbonus municipalities. The association with quality of care increased with the size of bonus: the largest bonus group saw an improvement of 8.2 percentage points (95% CI: 6.2 to 10.2; p < 0.001) compared with the control. The subgroup analysis showed that the observed improvement in performance was most pronounced in the poorest two-fifths of localities. The limitations of the study include the potential for bias from unmeasured time-varying confounding and the fact that the PMAQ score has not been validated as a measure of quality of care.ConclusionsPerformance bonuses to family health team workers compared with traditional input-based budgets were associated with an improvement in the quality of care.

Nasser Fardousi and colleagues investigate the association between performance bonuses and the quality of primary health care delivered by family health teams in Brazil.     

Team Work Load in an English General Practice—I

A survey of the total care provided by a general practitioner and his paramedical team for 3,137 patients in Teesside in 1972 showed that even in this area of high morbidity and mortality the work load was very small. The doctor held an average of 2·3 consultations per patient per year, and the overall average for the team of doctor, nurse, and health visitor was only 3·1. By delegating work to a team of trained paramedical workers, by increasing the proportion of personal medicine, and by engaging the co-operation of his patients, the general practitioner reduced his work load considerably, without any apparent reduction in standard of care.     

A national survey of laboratory animal workers concerning occupational risks for zoonotic diseases

In this cross-sectional survey of laboratory animal workers in the United States, 23 of 1367 persons reported 28 cases of infection with zoonotic agents from research animals at their workplace during the past 5 years, with six persons indicating that their infections were medically confirmed. Based on these data, the annualized incidence rate for work-related transmission of zoonotic agents from laboratory animals was 45 cases per 10,000 worker-years at risk (95% confidence interval, 30 to 65 cases), approximating the rate for nonfatal occupational illnesses in the agricultural production-livestock industry and for those employed in the health services during 2002. Logistic regression analysis found various characteristics of persons and their employers that were significantly associated with the likelihood of having been medically evaluated for exposure to a zoonotic agent from laboratory animals. Most (95.595% +/- 1.1%) persons working with laboratory animals or their tissues indicated that they knew whom to talk to at their institution for medical evaluation and care should they be concerned about the possibility of an occupationally acquired zoonotic disease in future. However, occupational illnesses and exposures among laboratory animal workers was underreported, as 10 of the 28 (36%) alleged zoonotic disease cases were not communicated to the employee's supervisor. Lack of concern about the potential significance to their health and the perception of punitive consequences to the employee were some of the reasons cited for underreporting, an issue which must be vigorously addressed in the interests of continuing progress toward zoonotic disease prevention in this field.     

Community Perceptions of Community Health Workers (CHWs) and Their Roles in Management for HIV,Tuberculosis and Hypertension in Western Kenya

Given shortages of health care providers and a rise in the number of people living with both communicable and non-communicable diseases, Community Health Workers (CHWs) are increasingly incorporated into health care programs. We sought to explore community perceptions of CHWs including perceptions of their roles in chronic disease management as part of the Academic Model Providing Access to Healthcare Program (AMPATH) in western Kenya. In depth interviews and focus group discussions were conducted between July 2012 and August 2013. Study participants were purposively sampled from three AMPATH sites: Chulaimbo, Teso and Turbo, and included patients within the AMPATH program receiving HIV, tuberculosis (TB), and hypertension (HTN) care, as well as caregivers of children with HIV, community leaders, and health care workers. Participants were asked to describe their perceptions of AMPATH CHWs, including identifying the various roles they play in engagement in care for chronic diseases including HIV, TB and HTN. Data was coded and various themes were identified. We organized the concepts and themes generated using the Andersen-Newman Framework of Health Services Utilization and considering CHWs as a potential enabling resource. A total of 207 participants including 110 individuals living with HIV (n = 50), TB (n = 39), or HTN (n = 21); 24 caregivers; 10 community leaders; and 34 healthcare providers participated. Participants identified several roles for CHWs including promoting primary care, encouraging testing, providing education and facilitating engagement in care. While various facilitating aspects of CHWs were uncovered, several barriers of CHW care were raised, including issues with training and confidentiality. Suggested resources to help CHWs improve their services were also described. Our findings suggest that CHWs can act as catalysts and role models by empowering members of their communities with increased knowledge and support.
