Evaluation of potential reduction in blood and body fluid exposures by use of alternative instruments

BACKGROUND: Injuries from needlestick, sharps injuries and splashes lead to exposure to blood and body fluids with the potential for transmission of blood-borne viruses. AIMS: To identify alternative instruments, which if used would improve worker safety. METHODS: Retrospective review of 161 injuries with identification of safer alternative products for instruments that caused injury. The proportion of injuries that could be prevented was calculated [with 95% confidence intervals (CI)]. RESULTS: The average rate of injury was 7.8/1000 employees per annum (95% CI, 6.8-9.4/1000). In the 2 years the highest rates of injury occurred in pre-registration house officers (164/1000; 95% CI, 64-264/1000), phlebotomists (154/1000; 95% CI, 15-291/1000) and senior house officers (45/1000; 95% CI, 13-77/1000). An upper estimate of 65% (95% CI, 58-72%) of incidents would have been preventable with a change to alternative devices. CONCLUSIONS: Change to the use of intrinsically safer instrumentation has the potential to prevent injury to healthcare workers.     

Risk perception and attitudes towards HIV in Serbian health care workers

BACKGROUND: Health care workers (HCWs) are at risk of occupational exposure to human immunodeficiency virus (HIV). AIM: To investigate the perception of professional risk from, and the knowledge, attitudes and practice of HCWs to HIV and AIDS in Serbia. METHODS: Cross-sectional study of 1,559 Serbian HCWs using self-administered anonymous questionnaires. Chi-square testing and multiple logistic regression analysis were applied. RESULTS: Eighty-nine per cent of HCWs believed that they were at risk of acquiring HIV through occupational exposure. The perception of professional risk was higher among HCWs frequently exposed to patients' blood and body fluids (OR 7.9, 95% CI 4.4-14.5), who used additional personal protection if the HIV status of patient was known (OR 2.6, 95% CI 1.5-4.6), who had experienced sharp injuries within the last year (OR 1.9, 95% CI 1.0-3.8) or who had been tested for HIV (OR 2.1, 95% CI 1.2-3.5), and among HCWs who had treated HIV-positive patients (OR 1.7, 95% CI 1.1-2.8). The majority of respondents had deficient knowledge about modes of HIV transmission. Attitudes towards HIV-positive patients were significantly different by occupation. Seventy per cent of HCWs used appropriate protection during their daily work with patients. CONCLUSIONS: HCWs require specific educational programmes and training protocols to ensure that they are adequately protected when carrying out high quality care.     

The impact of educational interventions on primary health care workers' knowledge of occupational exposure to blood or body fluids

AIM: To assess the impact of educational interventions on primary health care workers' knowledge of management of occupational exposure to blood or body fluids. METHODS: Cluster-randomized trial of educational interventions in two National Health Service board areas in Scotland. Medical and dental practices were randomized to four groups; Group A, a control group of practices where staff received no intervention, Group B practices where staff received a flow chart regarding the management of blood and body fluid exposures, Group C received an e-mail alert containing the flow chart and Group D practices received an oral presentation of information in the flow chart. Staff knowledge was assessed on one occasion, following the educational intervention, using an anonymous postal questionnaire. RESULTS: Two hundred and fifteen medical and dental practices were approached and 114 practices participated (response rate 53%). A total of 1120 individual questionnaires were returned. Face to face training was the most effective intervention with four of five outcome measures showing better than expected knowledge. Seventy-seven percent of staff identified themselves as at risk of exposure to blood and body fluids. Twenty-one percent of staff believed they were not at risk of exposure to blood-borne viruses although potentially exposed and 16% of exposed staff had not been immunized against hepatitis B. Of the 856 'at risk' staff, 48% had not received training regarding blood-borne viruses. CONCLUSIONS: We found greater knowledge regarding management of exposures to blood and body fluids following face to face training than other educational interventions. There is a need for education of at risk primary health care workers.     

Risks associated with occupational glass injury in bar staff with special consideration of hepatitis B infection

Since bar workers often sustain cuts from unwashed bar glasses,the aims of this study were to investigate risk of injury andto examine the sero-prevalence of markers for hepatitis B amongstbar staff. Ninety-one bar staff recruited by newspaper advertisementwere asked about injury experience and life-style risks associatedwith transmission of hepatitis B and were tested for hepatitisB surface antigen (HBsAg) and core antibody (anti-HBc). Seventy-fourper cent reported lacerations from broken glassware at work:18% had sustained such injuries in more than 10 incidents. Fifty-fiveper cent of respondents reported occupational skin contact withbody fluids. Anti-HBc prevalence for the study group was 1.1%,suggesting that bar staff were not at increased risk from hepatitisB infection. Although 30% wore gloves for high-risk tasks, therewas no evidence that glove wearing prevented glass lacerations.This level of injury experience and exposure to body fluidsis unacceptable and represents a potential risk of cross-infection.Hepatitis B immunization should be considered in this group.Urgent action, including the replacement, wherever possible,of annealed with tempered bar-glassware, is necessary to protectbar workers from glass injury.     

Morbidity in expatriates--a prospective cohort study

BACKGROUND: Expatriates comprise an important, but rarely studied subset of international travellers. This study was performed to assess the incidence of health events in an expatriate group and to evaluate factors affecting this incidence. METHODS: A cohort of 2020 Foreign and Commonwealth Office (FCO) staff and partners living abroad were followed-up over 1 year. The main outcome measure was incidence of illness or injury serious enough to require consultation with a doctor. Data collection was by means of a self-administered questionnaire. Poisson regression was used to estimate the rates of health events and to test for association between health events and a number of independent variables. RESULTS: The incidence of health events was 21%. Trauma (incidence 5%), musculoskeletal disorders (incidence 4%) and infectious disease (incidence 3%) were the principal causes of morbidity. The incidence of psychological disorders was low (1%). Of significance, employees were at increased risk of morbidity when compared to partners, with a higher incidence of health events [incidence rate ratio (IRR) 1.4, 95% CI 1.1-1.9] and psychological disorders (IRR 5.9, 95% CI 1.0-34.1). Moreover, unaccompanied employees were at increased risk of health events (IRR 1.3, 95% CI 1.0-1.7), and of traumatic injury (IRR 2.3, 95% CI 1.3-4.3) when compared to accompanied employees. CONCLUSION: While the morbidity in FCO personnel is low in comparison to other expatriate groups, the higher risk of morbidity in employees and unaccompanied individuals merits further research, particularly to ascertain whether work demands, isolation or risk-taking behaviour are contributory factors.     

Healthcare workers' risk of contact with body fluids in a hospital: the effect of complying with the universal precautions policy.

OBJECTIVE: To test whether healthcare workers' knowledge of and compliance with the basic principle of the Universal Precautions policy (i.e., that all patients should be treated equally regarding contact with body fluids) influenced the rate of contact with patient blood. DESIGN: Survey based on anonymous questionnaires. SETTING: A 380-bed secondary and tertiary care hospital receiving emergency and elective patients. PARTICIPANTS: All employees having any contact with patients. Nine hundred one of 1,308 (69%) of the questionnaires were returned. RESULTS: Twelve percent of the respondents (95% confidence interval [CI95] = 10.0%-14.4%) had experienced any contact with patient blood in the week preceding their answer. Physicians had the highest rate of contact with blood followed by nurses. In the five groups--physicians, nurses, laboratory technicians and phlebotomists, nursing aides, and student nurses--contact with blood was less frequent in the subgroup that did know and comply with the basic principle of the Universal Precautions policy, compared with the subgroup that did not. When adding the results for the 5 groups, contact with blood was experienced by 91 of 571 (15.9%, CI95 = 13%-19%) of the personnel who did not know and comply with Universal Precautions. The personnel who did know and comply with Universal Precautions had a significantly lower (9 of 111 [8.1%], p < .05, CI95 = 3.8%-15%) rate of contact with blood. CONCLUSIONS: The healthcare workers who knew and complied with Universal Precautions had a significant lower rate of contact with patient blood than those who did not.     

Risk factors for cytomegalovirus seropositivity in a population of day care educators in Montréal, Canada

BACKGROUND: Horizontal transmission of cytomegalovirus (CMV) is common in the day care setting. Day care educators appear to be at a high risk of infection; however, studies are limited. AIMS: To determine the proportion of CMV-seropositive female educators in the day care setting and to identify associated risk factors. METHODS: Educator- and day care-level risk factors for CMV seropositivity were obtained by questionnaires from day care educators and directors, respectively. Sera were collected from educators and analyzed by enzyme-linked immunosorbent assay. Significant independent risk factors for CMV seropositivity were determined using a multivariable logistic regression model which was fitted using the generalized estimating equation method. RESULTS: CMV seroprevalence in 473 female educators from 81 day care centers in Montréal, Canada, was 57%. Significant risk factors for CMV seropositivity were (i) increasing age (OR5-yr = 1.19; 95% CI = 1.05-1.35), (ii) low-income country of birth (OR = 10.23; 95% CI = 2.64-39.50) or middle-income country of birth (OR = 4.99; 95% CI = 2.39-10.40), (iii) having > or =2 children of their own (OR = 1.98; 95% CI = 1.19-3.31) and (iv) child-to-educator ratio >6 (18-35 months old) in a day care center (OR = 1.87; 95% CI = 1.25-2.81). CONCLUSIONS: Day care educators have risks for CMV infection related to their work in the day care setting, as well as personal risk factors. A review of current guidelines for the prevention of CMV infection in day care is needed to ensure that recommendations are evidence based.     

Does military service damage females? An analysis of medical discharge data in the British armed forces

There is anecdotal and some scientific evidence that females in military service experience an excess of work-related injuries, compared with males. To investigate this more fully, we analysed data collected routinely by the Defence Analytical Services Agency on medical discharges in male and female personnel in the British armed forces. We found that for all disease and injury categories of medical discharge there is a statistically significant excess in females; this disparity is particularly marked for discharges on account of injury [relative risk (RR) = 1.65, 95% confidence interval (95% CI) = 1.30-2.10] and musculoskeletal disease (RR = 3.34, 95% CI = 2.75-4.06). Royal Navy females are eight times more likely (RR = 7.92, 95% CI = 3.03-20.66) and Army females seven times more likely (RR = 6.53, 95% CI = 2.60-16.42) than Royal Air Force females to be medically discharged on account of injury. Over the period 1993-1996, there was a statistically significant increase in the rate of medical discharge for both musculoskeletal disease and injury in female personnel in the British armed forces. During the period 1996-2000, a marked gender differential was maintained, but the rate of increase in females reached a plateau. We concur with previous investigators that mixed-sex training imposes particular ergonomic stresses on females and that it is a major risk factor for overuse injury. We discuss other possible explanations for the marked gender differential in medical discharge rates in the military. Some changes to training programmes are now being introduced to correct this health inequality, but further interventions are needed. Modifications to training programmes must be audited systematically and candidate interventions tested through randomized controlled trials.     

A review of mental health morbidity associated with OFSTED inspections of schools in one metropolitan local authority

Anecdotally there appeared to be a relationship between OFSTED inspections and mental health morbidity. This study was set up to examine this relationship in one metropolitan local authority. Inspected schools were matched with schools from the same local authority that were not inspected. The rate of sickness absence per 100 whole time equivalent staff in inspected schools was 5.4 as compared with 2.1 in matched schools. The relative risk of a spell of sickness absence due to mental ill-health in an inspected versus an uninspected school was 2.52 (95% confidence interval = 1.19-5.31). The study indicates that there may be a relationship between the OFSTED inspection process and mental health morbidity. Some recommendations are made.     

Are endoscopy nurses at risk of infection with Helicobacter pylori from their work?

BACKGROUND: In response to studies suggesting risk of occupational transmission of Helicobacter pylori (HP) to endoscopy staff, this cross-sectional study of seroprevalence to HP in gastroscopy nurses working in West of Scotland hospitals (an area of high endemicity of HP infection) was performed to determine if they were at excess risk relative to peers working in surgical specialities but without gastroscopy exposure. The study aimed to fulfil employer's duties to carry out a suitable risk assessment required by health and safety legislation. METHOD: This cross-sectional study compares the seroprevalence of HP in gastroscopy nurses and comparators drawn from orthopaedic and trauma units in 10 hospitals during 1998. A directly administered questionnaire collated exposure information on occupational and non-occupational risk factors for infection. Venepuncture was performed for latex agglutination test for IgG to HP. Confounding by socio-economic factors was controlled for by multivariate analysis. RESULTS: Of the 222 participants, 74 were endoscopy staff (84% response) and 148 (59%) were comparators. Of these, 32.4% of gastroscopy and 33% of comparators were seropositive for HP (OR 0.97, P > 0.9, 95% CI 0.5-1.8). No association was found between gastroscopy exposure variables (frequency, years) or exposure to all endoscopy procedures and HP. Significant associations were found for age, childhood deprivation and greater number of siblings. CONCLUSION: No excess HP infection was found in gastroscopy nurses. Duties imposed by the health and safety legislation appear discharged by normal infection control procedures. Socio-economic factors are key determinants of HP status.     

Factors associated with occupational exposure and compliance with universal precautions in an urban school district.

Factors associated with occupational exposure and universal precautions (UP) compliance were assessed among employees in one urban school district. Half of the employees surveyed reported responding to bleeding injuries and cleaning blood or other body fluids (e.g., vomit, urine) during the previous school year. Also, 1 in 4 custodians and 1 in 10 teachers/teacher's aides had direct contact with blood or body fluids without protection. In multivariate logistic regression analyses, direct contact was most likely among secondary school employees in unpredictable situations who did not have protective equipment or comply with UP. UP compliance was greater among those who had protective equipment available and felt self-confident. Self-confidence was associated with having received training or protective equipment. Routine communications between administrators and employees, staff training, provision of protective equipment, and exposure incident monitoring are essential to effective implementation of UP policies in schools and work settings where occupational exposure could occur.     

Hospital laundry workers--an at-risk group for hepatitis A?

Twenty-two laundry personnel at St. Luke's Hospital, Malta, were tested for seropositivity to hepatitis A together with 37 nursing aides working in paediatric and infectious disease wards, matched for age, who were used as controls. IgG antibodies were found in 54.5% of laundry workers and 13.5% of nursing aides [odds ratio (OR) = 7.68; 95% confidence interval (CI) = 1.87-33.83]. Furthermore, laundry personnel consistently handling dirty linen prior to washing showed an OR of 16.50 (CI = 1.19-825.57) as compared with colleagues handling only clean items. These results would suggest that the increased exposure of hospital laundry workers to potentially infected linen can constitute a risk of occupational hepatitis A for this group of employees.     

Air blast circuit breaker noise and hearing loss: a multifactorial model for risk assessment

The assessment of the risk to hearing from impulse noise exposure may be a problem for the occupational physician because existing legislative and international noise exposure standards deal primarily with continuous noise, and are not valid in excess of the peak exposure limit of 200 pa (140 dB). Noise exposure in excess of this level, for example that due to firearms, is frequently perceived as harmful, but this is not necessarily the case, as impulse noise standards do, in fact, allow exposure with a maximum in the order of 6.3 kPa (170 dB). To illustrate this, a cross-sectional group of electrical transmission workers have been studied who were exposed to significant levels of impulse noise from air blast circuit breakers and firearms. Important hearing loss factors have been identified by means of a specially designed questionnaire. Using the Health & Safety Executive definition, the risk of hearing loss was determined by calculating prevalence odds ratios (ORs) for exposure to these factors. The OR for those with fewer than eight unprotected air blast circuit breaker exposures was 2.27 (95% confidence interval (CI), 1.01-5.08), whilst for those with more than eight exposures the OR was 2.10 (95% CI, 0.97-4.54). For firearm exposure, ORs of 1.61 (95% CI, 0.95-2.74) were noted in the medium exposure group and 2.05 (95% CI, 1.08-3.86) in the high exposure group. When all the factors were included in the model, the most significant factor was age. The study gives support to the impulse noise exposure criteria, confirming the borderline risk from air blast circuit breaker noise exposure and the relative safety of moderate gunfire exposure.     

Compliance with follow-up after occupational exposure to hepatitis C

BACKGROUND: Accidental percutaneous exposure to blood containing hepatitis C virus (HCV) is reported by health care workers more frequently than exposure to human immunodeficiency and hepatitis B virus. The transmission rate following such an exposure is approximately 1.9%. Little is known about the attendance rate of such staff for follow-up testing following exposure to HCV. AIM: To determine whether our follow-up programme for staff exposed to hepatitis C would allow the early detection and treatment of infected staff members. METHOD: We reviewed all staff exposures to hepatitis C reported to the occupational health department of a London teaching hospital over a 8-year period. RESULTS: Of 105 exposures, 21% of staff attended for early (6 or 12 weeks) and late (26 weeks) post-exposure follow-up. Thirty-seven per cent attended early follow-up only and 1% attended late having not attended early follow-up. Forty per cent did not attend any follow-up appointments with us. CONCLUSION: With the availability of effective treatment for early HCV infection, it is vital that occupational health departments encourage staff to attend at least for early follow-up. Access to HCV-RNA testing at this early stage should allow detection and early treatment of the small proportion who seroconvert.     

Lifestyle and the development of hypertension: a 3-year follow-up study of middle-aged Japanese male office workers.

The association of lifestyle factors with the development of hypertension (blood pressure > or = 140/90 mmHg) over a 3-year follow-up period was studied in 949 hypertension-free Japanese male office workers aged 35 to 54 years. From the Cox proportional hazards model, age, alcohol intake, body mass index (BMI) and hours of work were independent factors associated with the development of hypertension. Adjusted hazard ratios for 5-year increases in age, daily consumption of alcohol, 5-kg/m2 increases in BMI and working 10 hours per day or more were 1.18 [95% confidence interval (CI) = 1.02-1.35]; 1.53 (CI = 1.14-2.05); 1.79 (CI = 1.38-2.33) and 0.58 (CI = 0.41-0.82), respectively. In the analysis using logistic regression, BMI was independently related to working 10 hours per day or more, controlling for other lifestyle factors. Adjusted odds ratio for 5-kg/m2 increase in BMI was 0.66 (CI = 0.49-0.88). These results suggest that the influences of long working hours on blood pressure are likely to be indirectly mediated through less overall obesity.     

Cancer incidence and cancer mortality in a cohort of UK semiconductor workers, 1970-2002

OBJECTIVE: To examine cancer risks in a cohort of workers employed in the manufacture of semiconductors. METHODS: The mortality (1970-2002) and cancer morbidity (1971-2001) experienced by a cohort of 1807 male and female workforce employees from a semiconductor factory in the West Midlands (UK) have been investigated. Standardized mortality ratios (SMRs) and standardized registration ratios (SRRs) were used to assess mortality and morbidity, respectively. RESULTS: Overall mortality was close to expectation in males [SMR 99, 95% (confidence interval) CI 79-122] and significantly below expectation in females (SMR 74, 95% CI 65-85). Incidence of all sites of cancer was somewhat elevated in males (SRR 130, 95% CI 95-173) but close to expectation in females (SRR 94, 95% CI 82-109). There were significant deficits of deaths from cancer of the oesophagus in males and females combined and from cancer of the breast in females. Significantly elevated SRRs were found in males for cancer of the rectum [Observed (Obs) 6, SRR 284, 95% CI 104-619], in females for cancer of the pancreas (Obs 10, SRR 226, 95% CI 108-415) and malignant melanoma (Obs 11, SRR 221, 95% CI 110-396) and in males and females combined for cancer of the rectum (Obs 19, SRR 199, 95% CI 120-310) and malignant melanoma (Obs 12, SRR 217, 95% CI 112-379). Detailed work history data were unavailable for analysis. The finding of excess morbidity was not mirrored in the corresponding mortality findings. CONCLUSIONS: The study found elevated morbidity for a number of cancer sites that may be unconnected with occupation. Elimination of all possible occupational causes will, however, require more detailed analyses of cancer risks in relation to exposure histories.     

Receptionists' perceptions of violence in general practice

BACKGROUND: Violence and threatening behaviour towards health care employees is a recognized hazard. There is a lack of research into the perceptions of general practice (GP) receptionists about this important workplace hazard. AIM: To determine the factors that influence reception staff perceptions regarding the risk of future violent and threatening incidents at work. METHODS: A cross-sectional survey using a self-administered postal questionnaire was carried out among reception staff working in 49 GPs in two UK National Health Service Primary Care Trusts. RESULTS: Forty-nine (72%) practices agreed to participate. Two hundred and seven (68%) reception staff participated. Receptionists who reported having been threatened or attacked in the past 12 months were more likely to be worried about being threatened [odds ratio (OR) 4.9; 95% confidence interval (CI) 2.0-11.8] or attacked (OR 4.6; 95% CI 1.8-11.2) in the future. Receptionists with higher neuroticism scores were more worried about the future possibility of violence. Staff who felt safe and supported at work (P = 0.003) and staff who had lower background sources of stress at work (P < 0.001) were less likely to feel they would be threatened or attacked at work. Staff who had received training about violent and abusive incidents felt safer at work (OR = 1.27; 95% CI 1.04-1.55). CONCLUSION: Previous episodes of threats or attacks at work make receptionists more worried about future episodes. Factors which reduce reception staff anxieties about violence and threat at work are working in a supportive environment where work stressors are controlled and receiving training on how to deal with violent, threatening and difficult behaviour.     

Occupational factors associated with low back pain in urban taxi drivers

BACKGROUND: Urban taxi drivers differ from other professional drivers in their exposures to physical and psychosocial hazards in the work environment. Epidemiological data on low back pain (LBP) of this occupational group are very scarce. AIMS: To examine LBP in taxi drivers and its association with prolonged driving and other occupational factors. METHODS: We analyzed the cross-sectional data from the Taxi Drivers' Health Study. Standardized instruments were used to collect information on personal factors, work-related physical and psychosocial factors and driving time profiles. LBP prevalence was assessed using the modified Nordic Musculoskeletal Questionnaire. Multiple logistic regression models were employed for statistical analyses. RESULTS: Of 1242 drivers, 51% reported LBP in the past 12 months, significantly (P < 0.001) higher than other professional drivers (33%) in Taiwan. After adjusting for the effects of demographic characteristics, lifestyle factors, anthropometric measures and socioeconomic positions, we found that driving time >4 h/day [prevalence odds ratio (POR) 1.78; 95% CI 1.02-3.10], frequent bending/twisting activities while driving (adjusted OR 1.86; 95% CI 1.15-2.99), self-perceived job stress (POR 1.75; 95% CI 1.20-2.55), job dissatisfaction (POR 1.44; 95% CI 1.05-1.98) and registration type were the major occupational factors significantly associated with higher LBP prevalence in taxi drivers. CONCLUSIONS: We have identified that long driving time and several physical and psychosocial factors are associated with high prevalence of LBP in taxi drivers. This should be further investigated in prospective studies. Future studies are needed to examine the potential adverse effects of prolonged exposure to low levels of whole-body vibration.     

Investigation of cancer incidence and mortality at a Scottish semiconductor manufacturing facility

BACKGROUND: We became aware of concern about cancer at a Scottish semiconductor manufacturing facility in 1998. Aim To compare cancer experience among current and former workers at the facility, with an appropriate comparison population, making use of any readily available exposure information. METHOD: We obtained personnel and employment episode information from four sources within the company. Workers were flagged for death and cancer registrations at the National Health Service Central Register in Edinburgh. We constructed standardized registration and mortality ratios (SRRs and SMRs), using Scotland as the comparison, with and without an adjustment for deprivation. RESULTS: The main mortality analysis included 4388 workers, with a mean length of follow-up of 12.5 years. Overall mortality was substantially below that expected for men, and for women was slightly below expected. Total cancer registrations were close to expected levels for men and women. Four cancers produced noteworthy findings: malignant neoplasm of the trachea, bronchus and lung in women-deprivation adjusted SRR [95% confidence interval (CI), number of cases] 273 (136-488, 11 cases); malignant neoplasm of the stomach in women-adjusted SRR 438 (90-1281, three cases); and malignant neoplasm of the female breast-adjusted SRR 134 (82-206, 20 cases). The unadjusted SMR for male brain cancer was 401 (83-1172, three cases) and there was an additional non-fatal case. CONCLUSION: These findings, particularly those relating to lung cancer, though inconclusive, point to the possibility of a work-related risk of cancer that justifies further investigation.
