The health care industry
This article is concerned with technological change in industry over the last 20 years, its effect on the health of the worker, and the measures taken by the employer to control any risk arising therefrom. Technological change cannot be viewed in isolation. Although advances in technology and the introduction of new processes are the outward and most visible sign of change in work practices, in most cases it is managerial restructuring, political pressures, and changes in legislation which bring about far greater change and which in the long term may have a greater effect on the health of the worker. No industry illustrates this better that the National Health Service and more recently the rapidly expanding private health care sector.

Prevention of hepatitis B in the workplace by vaccination
La prévention de l'hépatite B professionnelle par la pratique vaccinale en médecine du travail [en francés]
Hepatitis B (HBV) remains a frequent and serious disease, sometimes still lethal. The best way to prevent it is vaccination. According to French legislation (CIS 91-1754), vaccination is compulsory for certain categories of workers. This responsibility is shared by workers, employers and physicians. All anti-HBV vaccines available today (whether plasma-based or manufactured by genetic engineering methods) are effective. This study reports on the very positive results of a vaccination campaign undertaken in France since 1981 among the workers of a large hospital.

Risk of workplace infection with the HIV virus
Risque professionnel d'infection par le virus de l'immunodéficience humaine [en francés]
Survey of existing knowledge concerning the risk of infection with the AIDS virus (HIV) among hospital workers in France, based in part on a study. Data are presented on the actual cases of occupational HIV infection found in France. The occupational risk of contamination is discussed. Recommendations are made as to the basic and absolutely necessary preventive measures to be applied both in the wards and in laboratory work: wearing of safety gloves and masks; safe handling of sharp objects; contamination etc. Action to be taken after an accident possibly involving contamination is discussed: notification of the accident, tests, repairs. Case-story of a nurse who suffered an accident with potential transmission of the HIV virus.

Blood contamination of medical staff and positive rate of HCV antibody in patients
Iryō jūjisha no ketsueki osen jiko to nyūin kanja no HCV kōtai yōsei ritsu [en japonés]
Between 1 June 1990 and 5 May 1991, 25 cases of blood contamination occurred at Kobe Rosai Hospital. Ten staff members were contaminated by blood from patients with anti-hepatitis C virus (HCV) antibody. Nine were treated with alpha-interferon; none of the 10 contracted hepatitis. Screening of inpatients for this antibody (C100-3) revealed a prevalence of 11.3%, which is almost 10 times the rate in normal subjects in Japan. The rate in patients with liver disease was 15.4%, and 4.8% in the other departments. Thus, the risk of HCV infection of staff is high. Patients should be screened for HCV on admission.

Cholylglycine measured in serum by RIA and interleukin-1β determined by ELISA in differentiating viral hepatitis from chemical liver injury
Serum bile acids have been shown to serve as useful indicators of liver disease. The study confirms these findings and adds an analysis of interleukin-1β (IL-1β) profiles to differentiate viral hepatitis from toxic liver damage associated with exposure to vinyl chloride (VC) or trinitrotoluene (TNT). The frequency of elevated cholylglycine (CG) was 100%, 75%, and 37.5% in viral hepatitis, VC- and TNT-linked liver-injury patients, respectively. The mean levels (µg/dL) were 578, 507, 142, and 65 in hepatitis B, hepatitis non-A non-B, VC and TNT liver-injury patients, respectively. The mean level of IL-1β in patients with hepatitis B was 424pg/mL and hepatitis non-A non-B was 384pg/mL compared with a mean of 33-40pg/mL in those with VC or TNT-linked liver disease. The IL-1β detection test proved further to be an important distinguishing parameter as it was 100% positive in patients with viral hepatitis but only 12.5% to 25% positive in patients with VC/TNT-induced liver damage.

Needlesticks: Preaching to the seroconverted?
This editorial on needlestick accidents discusses the potential for infectious disease transmission and the need for prevention strategies. The principal causes for concern are human immunodeficiency virus (HIV) and hepatitis B virus (HBV). Most of the work published on needlestick injuries concerns primary prevention (improved designs for the recapping and disposal of needles, staff training), while secondary prevention issues have been less publicised. It is argued that optimum management of injuries and peace of mind, particularly in less medically informed staff, demand a hospital policy for action and an expert contact for advice.

Behaviour of hospital staff regarding prevention. The case of hepatitis B.
Comportement du personnel hospitalier à l'égard de la prévention. Le cas de l'hépatite à virus B [en francés]
A programme of immunisation against hepatitis B was introduced at the university hospital of Rouen (France) in the 1980s. The mean participation rate (55,8%) was compared to the corresponding sero-prevalence according to various criteria: age, sex, seniority, professional category, and hospital department. Staff were classified into four categories, depending on whether their seropositivity rates and their participation rates in the vaccination programme were higher or lower than the average in the hospital. The young and/or recently employed staff had a higher participation rate. Surgeons and personnel with few qualifications had a lower participation rate despite a higher risk. Voluntary prevention programmes must be particularly concentrated and adapted to the more exposed and less qualified categories of staff.

Varicella-zoster virus susceptibility in day-care workers
The susceptibility of day-care workers to varicella-zoster virus (VZV) was evaluated by determining antibody to VZV in 545 day-care workers using an enzyme-linked immunosorbent assay (ELISA). The proportion of day-care workers susceptible to VZV was 4.8%, and the seronegativity among workers with a negative history of VZV infection was 13.6%. Susceptible workers identified by the serological screen should be sent home for 8-21 days after exposure if VZV infection occurs in the day care setting. All day-care workers of childbearing age should be given the option to be tested for immunity to VZV. Because reports indicate that adults from the tropics may have a higher susceptibility rate to VZV, it is recommended that all day-care workers from the tropics undergo serological screening.

Review of management of incidents involving exposure to blood in a London teaching hospital, 1989-91
The study reviews management of incidents involving exposure to blood involving 438 health care workers and students in a London teaching hospital from 1989 to mid-1991. A total of 447 incidents were reported: 337 sharps injuries and 110 other exposures. A total of 310 staff reporting incidents were already immune to hepatitis B virus. Of 345 source patients identified, 77 had already been tested for hepatitis B surface antigen (28 positive results) and 58 for HIV antibodies (18 positive results). Of those not previously tested, 145 of 266 were subsequently tested for hepatitis B surface antigen (two positive) and 149 of 287 for HIV antibodies (none positive). Specific hepatitis B immunoglobulin was given to 18 staff who were not immune and was avoided in 11 cases by a negative result for the patient. Management of exposure to blood is improved by widespread immunisation against hepatitis B virus and by knowledge of source patients' hepatitis B virus and HIV status.

La enfermería frente a las hepatitis B y C, como causa de enfermedad profesional: su prevención
The occupational risk of hepatitis B and C virus infection is considered to be a serious problem for nursing personnel. Statistics on the infected population with hepatitis B virus, in particular nursing staff, are given. Adequate information and barrier methods (gloves, masks, clothes) are indicated as preventive measures for this disease, as well as vaccination, which is discussed in more detail. With respect to hepatitis C virus infection, the situation seems to be more uncertain. However, in case of possibility of infection with this virus, the administration of standard gammaglobulin is recommended.

Prevalencia de marcadores de la hepatitis B entre el personal laboral de centros de infancia
The Department of Occupational Health of Cádiz (Spain) planned a programme for the prevention of hepatitis B in personnel of child assistance centres. This programme consisted of two subprogrammes: (1) information on the disease, its control, protection and prevention measures; and (2) vaccination. This article provides information on the first stage of the vaccination subprogramme aimed at examining the immunological condition of the population under study. The prevalence of hepatitis B markers in the study population was even higher than in general hospital personnel. For this reason, hepatitis B prevention and vaccination programmes are recommended in such institutions.

Occupational Exposure to Bloodborne Pathogens: Final Rule [USA]
This standard (effective 6 Mar. 1992), aimed at eliminating or minimising occupational exposure to bloodborne pathogens (particularly Hepatitis B Virus (HBV) and Human Immunodeficiency Virus (HIV)), concerns: definitions; exposure controls; methods of compliance (engineering and work practice controls, personal protective equipment, housekeeping); HIV and HBV research laboratories and production facilities; Hepatitis B vaccination and post-exposure evaluation and follow-up; communication of hazards to employees (labels and signs, information and training); recordkeeping. The introduction to the standard includes a very detailed discussion of: events leading to the standard; health effects of exposure to bloodborne pathogens (epidemiology and symptoms of Hepatitis B and AIDS; other bloodborne pathogens: syphilis, malaria, babesiosis, brucellosis, leptospirosis, arboviral infections, relapsing fever, Creutzfeldt-Jacob disease, human T-lymphotropic virus type I, viral haemorrhagic fever); quantitative risk assessment (principally among health-care workers); significance of risk; regulatory impact/flexibility analysis; environmental impact.

Negligible risk of horizontal transmission of hepatitis B virus among mechanics and salespersons in the automobile industry
Transmission of hepatitis B virus (HBV) among hospital patients and medical staff has been well documented. The high prevalence of hepatitis B antigen (HBsAg) carriers in the Japanese population makes horizontal transmission in other occupational settings a real concern, but the actual risk of HBV infection has been unknown. The permanent work force of 44 automobile dealerships in Akita Prefecture (220 locations) was screened for HBsAg as part of routine medical examinations. Blood samples positive for HBsAg were tested for HBV core antigen to confirm the presence of persistent infection. The prevalence of HBV infection was much higher among subjects aged 35-44 than in other age groups. This reflects the hepatitis epidemics that followed the introduction of pertussis and polio vaccination programmes in 1948. The fact that infection did not spread into other age cohorts in these workplaces indicates that the risk of horizontal transmission is negligible when contact with biological fluids is unlikely.

Occupational risk of hepatitis B for police and customs personnel
A cross-sectional study was undertaken to establish whether New Zealand police and customs officers are at excess risk of hepatitis B virus infection as a consequence of occupational exposure to human blood and penetrating injury. The control group was comprised of civilians employed by both police and customs organisations. The prevalence of hepatitis B markers in the control group, when standardised for age, sex and ethnic distribution, was 13.4%, which agrees well with New Zealand blood donor figures. The prevalence ratios for police officers and customs officers compared with the civilians (adjusted for age, sex, and ethnic distribution) were 0.82 (95% confidence interval (CI) 0.63-1.06) and 0.49 (95% CI 0.34-0.70), respectively. Multivariate analysis failed to demonstrate any significant association between occupational variables and marker prevalence. There was an association between time spent living in high-risk areas of the country and marker prevalence.

Costo-beneficio de la vacunación contra la hepatitis B en trabajadores de hospitales de Venezuela
A cost-benefit study of hepatitis B vaccination in Venezuelan hospital workers was performed through a decision tree analysis model, which includes the probabilities for the different outcomes of the hepatitis B virus infection (HBV). The current average cost of HBV infection to the Venezuelan Government was estimated at USD 1,759 per patient. Implementation of selective vaccination or a mass vaccination campaign for hospital workers would reduce the total cost of HBV infection by 49% and 72%, respectively, providing savings of USD 17 to 26 million. This type of economic analysis may influence the distribution of the resources to be allocated for the control of HBV infection in Venezuela. Summary in English.

Dimethylformamide-induced liver damage among synthetic leather workers
The purpose of this study was to determine liver damage associated with dimethylformamide (DMF) exposure. Liver function tests, and creatinine phosphokinase (CPK) determinations were performed on 183 workers of a synthetic leather factory. Air concentrations of solvents were also measured. High exposure concentrations of DMF (25-60ppm) were significantly associated with elevated alanine aminotransferase (ALT) levels (ALT≥35IU/L), a result that did not change even after stratification by hepatitis B carrier status. The study demonstrates that exposure to high concentrations of DMF was associated with an elevated ALT (p=0.01), whereas hepatitis B surface antigen was slightly but independently associated with an elevated ALT (p=0.07). In those workers who had normal ALT values, there occurred still significantly higher mean ALT and aspartate aminotransferase activities, especially among those who were not hepatitis B surface antigen carriers. A significant association existed between elevated CPK levels and exposure to DMF. Liver damage among synthetic leather workers is ascribed to DMF but it is recommended that the occupational standard for DMF and its toxicity among hepatitis B surface antigen carriers be evaluated further.

HIV infection. General rules for disinfection and risk prevention in the health professions
Infection à VIH. Règles générales de désinfection, prévention des risques dans les professions de santé [en francés]
The prevention of HIV infection should take into account not only the risks of infection by HIV itself but also the risk of associated infections, often asymptomatic (such as hepatitis B), as well as immunodepressive complications. The principles of disinfection and of estimating the activity of disinfectants are explained, along with applications and methods of use of antiseptics and disinfectants. The problem of the prevention of risks of infection in hospitals is also approached by considering risks for AIDS patients, other sick people and personnel. For health service and laboratory personnel, sources of contamination according to biological site are outlined along with exposure to risks according to post or service, and the frequency of accidents and seroconversions. Preventive measures include recommendations concerning containers for disposable soiled objects so as to avoid all contact with blood. Finally, measures to take in case of accident involving exposure to blood or biological products are described.

Are universal precautions effective in reducing the number of occupational exposures among health care workers? - A prospective study of physicians on a medical service
In a questionnaire survey 277 physicians were queried concerning incidents of exposure to blood and body fluids and barrier use before and after the implementation of universal precautions. Implementation increased the frequency of barrier use during exposure incidents, decreased the number of exposure incidents that resulted in direct contact with blood and body fluids and increased averted exposures in which direct contact was prevented by barrier devices. Thus, universal precautions were effective in reducing the risk of occupational exposures among physicians.

The occupational risk of cytomegalovirus infection among day-care providers
Of the 252 day-care providers studied at 6 day-care centres, 96 (38%) were seropositive for cytomegalovirus at entry into the study. Among 82 seronegative providers available for follow-up, 7 seroconversions occurred. It was estimated that the overall risk of seroconversion ranged from 0% to 22% by 12 months and from 0% to 40% by 16 months. Risk of cytomegalovirus acquisition was independent of the presence of a child at home or caring for young children in the centre, although the risk of seroconversion appeared to be related to the risk of cytomegalovirus acquisition among the children at each centre.

Occupational risk for hepatitis C virus infection among New York City dentists
Demographic, occupational and behavioural data were recorded for dentists in the New York City area and sera were tested for antibodies to HCV (anti-HCV). Anti-HCV was found in 8 (1.75%) of 456 dentists compared with 1 (0.14%) of 723 controls and in 4 (9.3%) of 43 oral surgeons compared with 4 (0.97%) of 413 other dentists. Seropositive dentists claimed to have treated more intravenous drug users in the week or month before the study than did seronegative dentists. Findings show that dentists are at increased risk for hepatitis C infection. It is concluded that all health-care workers should regard patients as potentially infected with a communicable bloodborne agent.

Reversal of non-responders and post-exposure prophylaxis by intradermal hepatitis B vaccination in Japanese medical personnel
Thirty-one Japanese non-responders to subcutaneous hepatitis B vaccination and 15 medical personnel who were accidentally exposed to specimens positive for hepatitis B e antigen and were given hepatitis B immunoglobin were intradermally immunised with hepatitis B vaccine every 2 weeks until delayed type hypersensitivity skin reaction to hepatitis B surface antigen (HBsAg) became positive. One year later, 74% of the non-responders still had sufficiently high levels of anti-HBsAg, while for the exposed personnel protection was 100%. Intradermal hepatitis B vaccination is therefore seen to be useful in reversing non-responsiveness to hepatitis B surface antigen and for prophylaxis after exposure.

Universal precautions and mortuary practitioners: Influence on practices and risk of occupationally acquired infection
Embalming, the most common funeral practice in North America, may expose the embalmer to infectious diseases and blood. 860 morticians in the US and Canada were surveyed in 1988 to estimate the incidence of self-reported occupational contact with blood and infectious disease, assess morticians' knowledge of acquired immunodeficiency syndrome (AIDS), determine their adherence to universal precautions, and identify predictors of practices designed to reduce risk of occupational exposure to infections. Of 539 (63%) respondents, 212 (39%) reported needle-stick injuries in the past 12 months, and 15 (3%) reported percutaneous exposures to HIV-contaminated blood. Those rating the risk of occupationally acquired human immunodeficiency virus infection as very high or high (194/539 [36%]) were more likely to decline funerals of bodies with antemortem diagnosis of AIDS (59/194 [30%]) and/or to charge more for such funerals (133/194 [69%]) than those who rated the risk as low to moderate (31/345 [9%], 174/345 [51%]).

Vaccine choice and program participation rates when two hepatitis B vaccines are offered
Participation rates of health care workers in voluntary free hepatitis B virus immunisation programmes are 35% to 40%. University teaching hospital employees at risk for hepatitis B virus and presenting for immunisation were surveyed as to vaccine preference. Both plasma-derived and recombinant hepatitis B virus vaccines were available. During a 10-month period, 173 health care workers enrolled in the study. One hundred seventeen received recombinant vaccine, and 56 received plasma-derived vaccine; 66 were immunised post-exposure. Concern of a relationship of human immunodeficiency virus to hepatitis B virus plasma-derived vaccine was acknowledged by a small number of health care workers as important in vaccine selection. Recombinant hepatitis B virus vaccine rapidly and substantially supplanted plasma-derived vaccine but did not increase programme participation. It is suspected that mandatory immunisation or proof of immunity will be necessary if hepatitis B virus protection rates in health care workers are to improve.

Act of 18 January 1991 and Orders of 6 February and 15 March 1991: Vaccination. Compulsory vaccinations. Conditions of immunisation [France]
Loi n°91-73 du 18 janvier 1991 et arrêtés du 6 février et du 15 mars 1991: Vaccination - Obligations. Conditions d'immunisation [France] [en francés]
All persons exposed as a result of their professional activity in a public or private health care or medical prevention establishment to the risk of contamination as well as all medical students must be immunised against hepatitis B, diphtheria, tetanus and poliomyelitis. Employees of biomedical analysis laboratories must also be vaccinated against typhoid fever. The cost of vaccination must be borne by the employer or the educational establishment concerned. The Order of 6 February 1991 lays down the conditions of immunisation of persons covered by article L.10 of the Public Health Code. The Order of 15 March 1991 provides a list of public or private health care or public health establishments in which exposed personnel must be vaccinated. Act No.91-73 was published in the Journal officiel of 20.01.1991. Decrees of 6 Feb. 1991 and 15 March 1991 were published in the Journal officiel of 21 Feb. 1991 and 3 April 1991, respectively.

Benefit-cost analysis of hepatitis B vaccine programs for occupationally exposed workers
The Occupational Safety and Health Administration of the US proposed a vaccination programme for workers exposed to the hepatitis B virus 12 or more times per year. A benefit-cost analysis was performed of the proposed regulation and of an expanded rule that covers all at-risk workers, regardless of the number of exposures. The annualised cost of the proposed vaccination programme is estimated at USD 60.4 million. The financial benefit of the programme was estimated using two methods. The first estimates the avoided cost of medical care, prophylaxis, and lost productivity at USD 124 million annually. The second approach includes the value of avoided pain and suffering from hepatitis B, thus increasing the total dollar benefit to USD 679 million. Although both methods indicate that benefits are greater than programme costs, the valuation of avoided pain and suffering substantially increases net benefits. Furthermore, provision of the vaccine to all exposed workers is cost-effective if one or more cases of hepatitis B are avoided per 6500 workers annually.

Attitudes and behaviors of medical technologists as a result of AIDS
To determine the influence of AIDS on the attitudes and behaviours of medical technologists, a survey was taken which shows that one quarter are considering leaving the profession. Individuals who plan to stay in the profession are less fearful of AIDS, more satisfied with the policies their organisations have established regarding the disease, and less willing to associate a declining employment situation with it. Improvement in safe laboratory practices is present in both groups, but the individuals considering a move out of the field exhibit the largest change. A surprising result is that fear of AIDS is not related to or only weakly associated with traditional demographic and occupational variables, suggesting that other more complex factors are influencing the views and work habits of medical technologists as a result of AIDS.

Research in occupational health: the UK National Health Service
This article discusses the scope of research to be carried out in the UK National Health Service which, if allied to occupational health practice, might have important direct or indirect benefits for patient care. General research topics that await further study include: health inequalities amongst health care workers, job stress, back problems, pregnancy, and infection risks from blood. Topical specific hazards include gluteraldehyde, cytotoxic drugs, nuclear magnetic resonance imaging, and implications of new technology in surgery. The co-ordination of databases across different district health authorities would be very useful for epidemiological research, the delivery of OSH services and the development of vaccination strategies.
