A descriptive study of blood exposure incidents among healthcare workers in a university hospital in Sweden

Mapping the Scientific Research on Healthcare Workers' Occupational Health: A Bibliometric and Social Network Analysis

In the last few years, the occupational health (OH) of healthcare workers (HCWs) has been shown increasing concern by both health departments and researchers. This study aims to provide academics with quantitative and qualitative analysis of healthcare workers’ occupational health (HCWs+OH) field in a joint way. Based on 402 papers published from 1992 to 2019, we adopted the approaches of bibliometric and social network analysis (SNA) to map and quantify publication years, research area distribution, international collaboration, keyword co-occurrence frequency, hierarchical clustering, highly cited articles and cluster timeline visualization. In view of the results, several hotspot clusters were identified, namely: physical injuries, workplace, mental health; occupational hazards and diseases, infectious factors; community health workers and occupational exposure. As for citations, we employed document co-citation analysis to detect trends and identify seven clusters, namely tuberculosis (TB), strength training, influenza, healthcare worker (HCW), occupational exposure, epidemiology and psychological. With the visualization of cluster timeline, we detected that the earliest research cluster was occupational exposure, then followed by epidemiology and psychological; however, TB, strength training and influenza appeared to gain more attention in recent years. These findings are presumed to offer researchers, public health practitioners a comprehensive understanding of HCWs+OH research.

Laboratories

Patient test samples are taken and examined at outpatient clinics, in bed posts and at policlinic consultations and treatment units. They are collected and transported to central laboratories or examined by smaller laboratory units, adapted to the patient group. Samples are sent in pipes or transported by defined methods to the laboratory. A large number of samples are also sent to other hospitals, laboratories or diverse private laboratories.

The following chapter is focused on laboratory safety for patients and personnel to avoid spread of infections between patients, personnel and environment.

Comparison of awareness about precautions for needle stick injuries: a survey among health care workers at a tertiary care center in Pakistan

Background

Needle stick injuries (NSIs) have the potential of causing Hepatitis B and Hepatitis C, which is constantly adding to the burden of chronic liver disease in our country. It poses a risk to Health Care Workers (HCWs) and the patients they deal with. In order to limit the spread of these viruses, it is imperative that these HCWs be fully equipped with knowledge regarding prevention of NSIs and dealing with one, regardless of their designation. We therefore aimed to assess and compare the level of awareness about precautions for needle stick injuries amongst all those greatest at risk.

Methods

This was a cross- sectional study carried out at Liaquat National Hospital, Karachi, Pakistan. A 23 itemed self-administered questionnaire was given to hospital staff including doctors, lab technicians and nurses via convenience sampling, in various departments. Data was analyzed via SPSS 18 software and a p-value of <0.05 was considered significant.

Results

A total of 198 responses were taken for this study, out of which 70 (35.4 %) were doctors, 70 (35.4 %) nursing staff and 58 (29.3 %) laboratory technicians. Of all HCWs, 101 (51 %) knew that the standard method of discarding needles is without recapping. 159 (80.3 %) were still recapping needles. 180 (90.9 %) HCWs were vaccinated against Hepatitis B. 36 (18.2 %) were aware that blood should be allowed to flow after an NSI and site of prick should be washed with an antiseptic.

Conclusion

The awareness was found to be very low amongst all HCWs. It should therefore be made compulsory for all HCWs to attend proper preparatory classes by the infection control department at the time of employment in order to improve the level of awareness and ensure safe practices.

The acceptable duration between occupational exposure to hepatitis B virus and hepatitis B immunoglobulin injection: Results from a Korean nationwide, multicenter study

BACKGROUND

Postexposure prophylaxis for occupational exposure to hepatitis B virus (HBV) plays an important role in the prevention of HBV infections in health care workers (HCWs). We examined data concerning the acceptable duration between occupational exposure and administration of a hepatitis B immunoglobulin (HBIG) injection in an occupational clinical setting.

METHODS

A retrospective analysis was conducted with data from 143 cases of HCWs exposed to HBV in 15 secondary and tertiary teaching hospitals between January 2005 and June 2013. Data were taken from the infection control records of each hospital.

RESULTS

Active vaccination after HBV exposure was started in 119 cases (83.2%) and postvaccination testing for hepatitis B antibody showed positive seroconversion in 93% of cases. In 98 cases (68.5%), HBIG was administered within 24 hours after HBV exposure; however, 45 HCWs (31.5%) received an HBIG injection more than 24 hours postexposure and 2 among the 45 received an injection after 7 days. Although 31.5% received an HBIG injection more than 24 hours postexposure, no cases of seroconversion to hepatitis b antibody positivity occurred.

CONCLUSIONS

For susceptible HCWs, HBIG administered between 24 hours and 7 days postexposure may be as effective as administration within 24 hours in preventing occupational HBV infection.

Suture needle handling in the operating theatre; what is the safest method? A survey of surgical nursing opinion

INTRODUCTION

Suture needle handling methods vary extensively between units. Securing the needle tip by locking it against the shaft of the needle holder prior to transfer (protected method) has been suggested to improve safety, although this is not evidence based. Some teams prefer to transfer the needle mounted perpendicularly to the needle holders with the tip exposed (unprotected method). We investigated scrub nurses' preferred method of needle transfer, and noted the safety of each by investigating their experience of needlestick injuries (NSIs).

METHOD

Scrub nurses from Oxford University Hospitals Trust, Chelsea and Westminster and Wexham Park Hospitals were surveyed anonymously between November 2013 and August 2014. Nurses selected their preferred method (protected, unprotected or either), and indicated previous NSIs with either technique. Multinomial regression analysis and χ(2) with Yates correction were used to assess associations.

RESULTS

One hundred and seven scrub nurses from 12 specialities were interviewed. 80/107 (75%) preferred protected transfer, 20/107 (19%) preferred unprotected transfer and 7/107 (6%) expressed no preference. There was no significant association between needle-mounting preference and years of scrub experience or speciality. Significant differences between preferences and four of the six hospitals were observed. Nine (9/107, 8%) scrub nurses reported NSIs with the protected method compared with 40 (40/107, 37%) in the unprotected group, this difference being statistically significant (p<0.001, χ(2)=25.17). Five (5/107, 5%) reported NSIs with both methods.

CONCLUSIONS

Protected needle transfer seems safer than the unprotected method. Needle-handling guidelines and appropriate training are required to help prevent the occurrence of NSIs in the operating theatre.

Age and years in practice as factors associated with needlestick and sharps injuries among health care workers in a Portuguese hospital

Health care workers are attributed to the group at highest risk of occupationally acquired bloodborne diseases as the result of contact with blood and body fluids. A cross sectional study was conducted between November 2009 and February 2010 in the North of Portugal, to identify potential risk factors for needlestick and sharps injuries. A questionnaire was provided to 363 health care professionals. Logistic regression was used to identify risk factors associated to needlestick and sharps injuries, calculating odds ratio (OR) and their 95% confidence interval (CI). Sixty-five percent of health care workers (64.5%, 234/363) reported needlestick and sharps injuries in the previous 5 years. Of the injured workers, 74.8% were nurses. Of the total injuries reported, the commonest were from syringe needle unit. The multivariate logistic regression model showed that the strongest risk factor was having more than 10 years or more of work in health services (OR 3.37, 95% CI 1.82, 6.24). Another significantly related factor was being over 39 years-old (OR 1.94, 95% CI 1.03, 3.63). In Portugal, there is a lack of epidemiological evidence related to needlestick and sharps injuries. Considering that patients infected with hepatitis B and C virus are commonly encountered in the hospital environment and that the prevalence of HIV infection in Portugal is one of the highest in Europe, these results should be considered in the design of biosafety strategies at the Hospital Center.

Review of standard precautions and sharps management in the community

Standard precautions are imperative for staff and patient safety and provide a basis for sound infection control practice in all health-care settings. One key element of these precautions relates to the safe handling and management of sharps to prevent occupational acquisition of blood-borne viral infection. Many inoculation injuries could be avoided by following standard precautions whenever contact with blood or body fluids is anticipated. However, evidence suggests that compliance with standard precautions is inadequate. With the modernization of the health service in the UK, community health care is becoming more complex, potentially increasing the risk of inoculation injury to community nurses. Although compliance with standard precautions in hospitals is well documented, there is limited research specific to community nurses. This review examines compliance with standard precautions by community nurses and discusses some strategies aimed at improving compliance with one of the key elements of standard precautions, i.e. sharps management.

Patients' conceptions of quality care and barrier care

AIM

To describe patients' conceptions of quality care and barrier care.

METHODS

As this study concerned conceptions of care, a phenomenographic approach was chosen. Fourteen adult orthopaedic patients participated. Data-collection was performed by means of semi-structured interviews. The qualitative data were analysed with two foci, conceptions of quality care and conceptions of barrier care. Different categories of understanding, that is, conceptions, constitute the the essential outcome of phenomenographic analysis. The research was conducted in one county hospital and in one regional hospital situated in different cities in the south of Sweden.

RESULTS AND CONCLUSIONS

Patients' conceptions of quality care resulted in six categories. When comparing the findings with previous research in this field, the findings of the present study confirmed to a large extent the findings from other studies of quality care. Patients' conceptions of barrier care resulted in five categoris. The conceptions of barrier care must be considered as elements in patients' conceptions of quality care, and this must be called atention to in efforts to measure patient satisfaction and in analyses of good care. It also can influence health care workers' compliance to guidelines in infection control procedures.

The health beliefs of hospital staff and the reporting of needlestick injury

AIM

The aim of this study is to examine the connection between the health beliefs of hospital staff (doctors, nurses and auxiliary staff) and their failure to report needlestick injuries.

BACKGROUND

Needlestick injury to hospital staff is quite frequent and can result in infections and disease, but staff frequently do not report the injury despite their awareness of the risk of blood-borne pathogens.

METHODS

Five questionnaires were constructed based on three existing research tools and were tested for validity and reliability. Two hundred and forty questionnaires were distributed to eight randomly chosen departments of a single Israeli hospital. Seventy-six percent of the questionnaires were anonymously completed and returned.

RESULTS

Nurses had the highest rate of needlestick injury, followed by auxiliary staff and doctors. Auxiliary staff showed the highest rate of compliance with the duty to report such injuries, while doctors showed the lowest. Perceived severity of contractable disease, the perceived efficacy of reporting injuries and overall motivation to maintain health were the best predictors of reporting compliance. Non-compliers emphasized the negative aspects of reporting the injuries, primarily that it took up too much time.

CONCLUSIONS

The solution to non-compliance with the duty to report must be a targeted investment in training and education. Relevance to clinical practice. Finding the reasons for compliance and non-compliance with the duty to report needlestick injuries will help in designing educational programmes for hospital staff and in determining a strategy for improving health behaviour.

Self-reported infection control practices and perceptions of HIV/AIDS risk amongst emergency department nurses in Botswana

This descriptive exploratory study investigated the reported practices and perceptions of emergency nurses related to infection control in the context of the Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) pandemic in Botswana. Quantitative and qualitative data were collected using a self-administered questionnaire. Forty questionnaires were distributed to nurses with emergency department experience in Botswana, with a response rate of 55% (n = 22). Quantitative data were analysed using descriptive statistics while qualitative data were subjected to thematic and content analysis. The majority of respondents reported compliance with universal precautions at the hospital emergency department. However, qualitative data highlighted resource constraints that may hinder compliance with universal precautions such as a lack of appropriate facilities, a shortage of equipment and materials, inadequate staffing and absence of sustainable in-service education programs. Further, the reported compliance with Universal Precautions had not removed the fear of exposure to HIV/AIDS and perceived risk of transmission to family. The authors recommend in-service education and practice initiatives to promote sustainable compliance with universal precautions and realistic risk perception among nurses. Further research is required to evaluate nurses' compliance with universal precautions in developing countries using observational methods or in-depth interviews. This would enable exploration of nurses' actions regarding compliance with universal precautions.

Coverage of hepatitis B vaccination in Swedish healthcare workers

The aim of this study was to assess how well the guidelines on vaccination against hepatitis B had been implemented among healthcare workers (HCWs) at risk for blood exposure. A point-prevalence survey was conducted in six departments of a university hospital in Sweden: the emergency room, intensive care unit, postoperative unit, surgical theatre, department of anaesthesiology and the laboratory for blood chemistry. All HCWs who worked in these departments during the 24h of the survey were asked to complete a questionnaire. In total, 369 questionnaires were analysed. Seventy-nine percent (293/369) of HCWs had received at least one dose of vaccine, but only 40% (147/369) reported that they were fully vaccinated and 21% (76/369) had not been vaccinated at all. The majority of unvaccinated HCWs (72/76, 95%) stated that they would accept vaccination if offered. The main barrier to better compliance with the guidelines is not lack of acceptance among the employees but the failure of the employer to ensure that policies are implemented.

Epidemiological characteristics of occupational blood exposures of healthcare workers in a university hospital in South Korea for 10 years

This study investigated the epidemiological characteristics of occupational blood exposures (OBEs) of healthcare workers (HCWs) in South Korea, and examined trends of OBEs after implementing blood exposure prevention (BEP) programmes. The study was conducted between 1 January 1992 and 31 December 2001 at a university-affiliated acute care hospital in Seoul. The BEP programmes comprised in-service education, hepatitis B virus (HBV) vaccination, and postexposure evaluation and prophylaxis. From 959 reported cases of OBEs, the crude incidence density (ID) was 2.62 cases per 100 person-years. The major risk groups for OBEs were physicians (ID 4.34) and new employees. The major type of OBE was from sharps injuries, including needlesticks (94.0%). OBE cases occurred more frequently during the spring (36.4%). The frequency of the serological tests of anti-hepatitis B surface antigen of HCWs changed significantly each year (P<0.05). The major serological risk for source patients was HBV (52.1%), but the risks for hepatitis C virus (HCV) and human immunodeficiency virus (HIV) increased significantly each year (P<0.05). There were no seroconversion cases following OBEs among the tested HCWs. In summary, we established the epidemiological characteristics of OBEs in a South Korean university hospital, and reduced the risk of OBEs of major risk groups by BEP programmes. We also found an increase in the risk of HCV and HIV during the study period, suggesting that OBEs could be a serious threat to HCWs.

Epidemiology of needlestick injuries among health care workers in a secondary care hospital in Saudi Arabia

BACKGROUND

Accidental needlestick injuries sustained by health care workers are a common occupational hazard in health care settings. The aim of this study was to review the epidemiology of needlestick injuries in Buraidah Central Hospital, a 212-bed secondary care hospital in Buraidah, Saudi Arabia.

METHODS

We conducted a retrospective survey of all self-reported documents related to needlestick injuries, for the period January 2002 through December 2003. The data was analyzed to determine the age, sex and job category of the health care worker suffering the injury as well as the risk factors responsible for needlestick injuries.

RESULTS

During the 2-year period, employees reported 73 injuries from needles and other sharp objects. Nurses were involved in 66% of instances, physicians in 19%, technicians in 10%, and nonclinical support staff in 5.5%. The majority (53.4%) of the injuries occurred after use and before disposal of the objects. Syringe needles were responsible for 63% of all injuries. Most injuries occurred during recapping of used needles (29%), during surgery (19%), and by collision with sharps (14%). Disposal-related (11%) causes as well as injuries by concealed sharps (5%) occurred while handling linens or trash containing improperly disposed needles.

CONCLUSION

This data emphasizes the importance of increased awareness, training and education of health care workers for reporting and prevention of needlestick injuries.

Blood exposure: factors promoting health care workers' compliance with guidelines in connection with risk

BACKGROUND

Health care workers compliance with guidelines, universal precautions, in connection with tasks that could involve contact with patient's blood is unsatisfactory. In a previous paper, we identified different forces that undermine compliance. Socialization into infection control, routinization, stereotyping, perceptions of patients' wishes and the presence of competing values and norms are examples of such forces.

AIMS AND OBJECTIVES

The aim of this article is to describe and analyse different forces that promote adherence to universal precautions. Behavioural variations are seen as a consequence of differences between wards with regard to the safety culture. Safety culture is conceptualized as the outcome of a constant interplay between deactivating and reactivating forces. In this article the focus is on the latter.

METHOD

The grounded theory approach. Data were collected through interviews with nurses and assistant nurses.

RESULTS

The charge nurse, informal leaders, students, infection control nurses, type of work, availability of equipment, blood-exposure incidents and media-coverage of infectious diseases are described as potentially important for compliance. The properties these agents must possess in order to be influential are also described.

RELEVANCE TO CLINICAL PRACTICE

The outcome of an occupationally acquired infection can be fatal. Hence it is important that health care workers take protective measures. The results imply that mere information about safe practices alone is insufficient to achieve that goal. All factors of importance for compliance must be taken in to consideration in clinical work and in education.

Uptake of guidelines to avoid and report exposure to blood and body fluids

BACKGROUND

Mucocutaneous and percutaneous exposure to blood and body fluids (inoculation injury) are major risk factors for occupational acquisition of bloodborne infection in health care professionals. Compliance with prescribed 'universal precautions' during exposure-prone procedures has been shown to reduce the risk of acquiring bloodborne viral infection. In addition, reporting such exposures facilitates prophylaxis.

AIM

The aim of this paper is to report a study to identify strategies to minimize professionals' risks of acquiring bloodborne infections during exposure-prone procedures.

METHOD

All surgeons, theatre nurses who scrub for surgery and midwives employed in general operating theatres and delivery suites within one UK National Health Service trust (n = 276) were surveyed by postal questionnaire. Data were analysed using univariate and bivariate techniques in SPSS version 10. Content analysis was undertaken on the one open-ended question.

FINDINGS

The response rate was 72.5% (200/276). Only 1.5% (3/200) of respondents adopted universal precautions for all patients irrespective of whether their bloodborne viral status was known. On average, only half the recommended theatre-specific precautions were always adopted (mean 3.725/7, SD = 1.385). Most respondents (63.3%) admitted making judgements related to nationality, lifestyle or sexual orientation when making decisions about protective clothing. Many respondents (74%, 145/196) reported sustaining an inoculation injury in the 10 years prior to the study. However, under-reporting of injuries was common, and 32.4% (47/145) admitted failing to report injuries. Guideline adherence was influenced by profession, but not by time since qualification.

CONCLUSIONS

The findings suggest that strategies must be developed to improve compliance with universal precautions and reporting guidelines by all health care professionals. The extent of, and reasons for, non-compliance with both local and national guidelines remain relatively unexplored.

Occupational blood and body fluids exposures in health care workers

The risk of accidental blood and body fluid (BBF) exposure is a daily concern for health care workers throughout the world, and various strategies have been introduced during the past decade to help reduce that risk. To assess the impact of multifocal reduction strategies introduced in hospitals affiliated with the Northern France network, we recently examined data from 4 years of BBF-exposure reports filed by network employees. A total of 7,649 BBF exposures were reported by health care workers to occupational medicine departments in 61 hospitals. Nurses and nursing students accounted for 4,587 (60%) of exposures, followed by nurses' aides and clinicians. Most (77.6%) of the reports were related to needlestick injury (NSI). In addition, we examined BBF exposure trends over time by analyzing data from 18 hospitals (29.5%) with data available for the time period of 1995 to 1998. These were assessed in nurses, who have the highest and most consistent reporting rate. We noted that the BBF-exposure incidence rate for all BBF exposures in nurses decreased from 10.8 to 7.7 per 100 nurses per year between 1995 and 1998 (P <.001), whereas the NSI rate decreased 8.9 per 100 nurses per year in 1995 to 6.3 in 1998 (P <.001). The percentage of NSIs that resulted from noncompliance with universal precautions also decreased significantly (P =.04). Widespread improvements in procedures and engineering controls were implemented in the Northern France network before and during the study period. Significant reductions were observed in reports of BBF exposures and NSIs, particularly in nurses. These findings are similar to those in other countries and reflect the overall improvement in the management of occupational risk of BBF in health care workers.

Health care workers' action strategies in situations that involve a risk of blood exposure

Previous research shows that health care workers (HCWs) often act in a risky way in blood-exposure situations, and thereby run the risk of becoming infected by blood-borne pathogens. A qualitative study was conducted in order to describe factors that influence HCWs' actions in such situations. Nurses and nursing assistants were interviewed. The analysis shows that HCWs perceive that there is a conflict among different demands. These demands are protecting the patient's privacy, protecting themselves from being infected and respecting the norms of the department. The process of managing this conflict is labelled 'balancing', which most often results in the choice of a diagnosis-related strategy.

Sharps-related injuries in California healthcare facilities: pilot study results from the Sharps Injury Surveillance Registry

BACKGROUND AND OBJECTIVES

In 1998, the California Department of Health Services invited all healthcare facilities in California (n = 2,532) to participate in a statewide, voluntary sharps injury surveillance project. The objectives were to determine whether a low-cost sharps registry could be established and maintained, and to evaluate the circumstances surrounding sharps injuries in California.

RESULTS

Approximately 450 facilities responded and reported a total of 1,940 sharps-related injuries from January 1998 through January 2000. Injuries occurred in a variety of healthcare workers (80 different job titles). Nurses sustained the highest number of injuries (n = 658). In hospital settings (n = 1,780), approximately 20% of the injuries were associated with drawing venous blood, injections, or assisting with a procedure such as suturing. As expected, injuries were caused by tasks conventionally related to specific job classifications. The overall results approximate those reported by the Centers for Disease Control and Prevention's National Surveillance System for Health Care Workers and the University of Virginia's Exposure Prevention Information Network.

CONCLUSION

These data further support findings from previous studies documenting the complex and persistent nature of sharps-related injuries in healthcare workers. In the future, mandated reporting using standardized forms and consistent application of decision rules would facilitate a more thorough analysis of injury events.

Análise dos acidentes com agulhas em um hospital universitário: situações de ocorrência e tendências

Os acidentes com agulhas constituem um dos principais riscos de transmissão ocupacional de infecções por via sangüínea (AIDS, hepatite B e C). É prioritário, portanto, discutir estratégias de intervenção baseadas nas fontes de risco. O objetivo deste estudo foi analisar os acidentes com agulhas ocorridos em um hospital universitário. A construção de um banco dados dos acidentes notificados, entre 1990 e 1996, permitiu identificar as situações de ocorrência e as tendências ao longo dos anos. Os resultados indicam que a maioria dos acidentes estava relacionada à realização ou auxílio de procedimentos. A implantação das primeiras medidas preventivas (precauções universais) aponta para a redução no total de acidentes com perfurações. Não foram observadas alterações nas taxas de acidentes relacionados à prática de reencapar agulhas. Discute-se o uso de diferentes estratégias de intervenção: introdução de materiais de design seguro; mudança de enfoque no treinamento e reorganização do ambiente e das práticas de trabalho.

Changing Knowledge, Behavior, and Practice Related to Universal Precautions Among Hospital Nurses in China

PURPOSE

To evaluate the effect of an educational training program for hospital nurses on universal precautions in Changsha, Hunan Province, People's Republic of China.

METHOD

Using a quasi-experimental design, 50 of 100 randomly selected hospital nurses were randomly assigned to receive an educational intervention. Questionnaires were administered to the 100 nurses prior to and 4 months after the training.

FINDINGS

Knowledge, practice, and behaviors related to universal precautions and the prevalence of hepatitis B immunization improved among nurses in the group who received training. No significant change in the frequency of glove use was found. Underreporting of sharps injuries to hospital authorities continued in both groups.

CONCLUSION

Although educational training significantly improved Chinese nurses' knowledge, practice, and behavior related to universal precautions, there remains room for improvement in glove use and needlestick injury reporting.

Epidemiology of biological-exposure incidents among Spanish healthcare workers

OBJECTIVE

To determine the frequency and the epidemiological characteristics of biological-exposure incidents occurring among healthcare personnel.

DESIGN

Prospective surveillance study.

SETTING

Participating Spanish primary-care and specialty centers from January 1994 to December 1997.

PARTICIPANTS

70 centers in 1994, 87 in 1995, 97 in 1996, and 104 in 1997.

METHODS

Absolute and relative frequencies were calculated for several variables (position held, area of care, type of injuring object, activity, etc) and for the different categories of each variable.

RESULTS

There were 20,235 registered incidents. Annual incidence rates were as follows: 1994, 51 per 1,000; 1995, 58 per 1,000, 1996, 54 per 1,000; and 1997, 59 per 1,000. Mean age of accident victims was as follows: 1994, 35.68 (standard deviation [SD], 16.26); 1995, 33.6 (SD, 11.9); 1996,38.2 (SD, 17.27); and 1997, 36.7 (SD, 16.33) years. Of the 20,235 incidents, 15,860 (80.7%) occurred to women; 50% (9,833) accidents were among nursing staff. The type of incident most frequently reported was percutaneous injury (81.1%). The highest frequency of accidents was seen in medical and surgical areas (28% and 25.6%, respectively). Blood and blood products were the most commonly involved material (87.6%). Administration of intramuscular or intravenous medication was the activity associated with the highest accident rate (20.3%). The most frequent immediate action in response was rinsing and disinfecting (65.6%).

CONCLUSIONS

The incident registry was highly stable in terms of incidence rates over the observation period and served to highlight the large number of incidents recorded each year. The potential implications of the results are the need to explore reasons for increased exposures in certain areas, with the aim of focusing prevention efforts, and, similarly, to establish the factors associated with diminished incidence rates to model successful measures.

[Occupational exposures to blood-borne pathogens in health care workers]

OBJECTIVE

To determine the rate of occupational exposures to blood-borne pathogens in different occupations of health care workers. To analyze the characteristics and outcome of the occupational exposure.

MATERIAL AND METHODS

We have evaluate occupational exposures to blood-borne pathogens reported by health care workers during 1996-1999. The following data were collected: characteristics of the workers, type of occupational exposure, immunity status of the exposed worker, infectivity of the source patient and follow up serologic testing of the worker.

RESULTS

A total of 407 occupational exposures were reported. The highest rate of occupational exposure was found among nurses (61.6%). Needlestick accident was the most often occupational exposure reported (84.5%). Mucosal exposures with accidental splashes were reported in 15.2% of cases. In 14.5% of these accidents workers were at risk for occupational transmission of blood-borne pathogens. Among the different occupations of health care workers, the rate of exposures with a source infected patient was higher in medical staffs (28.3%) than nurses (13.9%) The rate of exposures with a source infected patient was higher in accidental splashes than in percutaneous exposures (33.8% vs 13.3%), besides in none of the accidental splashes, employees had used appropriate barrier precautions. There were no cases of transmission of occupational blood-borne infections.

CONCLUSIONS

Although nurses are the health care workers with highest rates of occupational exposures, medical staffs are the most often occupationally exposed to a source infected patient. Universal barrier precautions are no appropriately used in most of the occupational accidents, specially in those involving mucosal exposures.

Aplicação do modelo de crenças em saúde na prevenção dos acidentes com agulha

OBJETIVO: Para prevenir a aquisição de infecções sangüíneas (Aids, hepatites B e C) por profissionais de saúde, recomenda-se não reencapar agulhas. Entretanto, esses profissionais não adotam essa recomendação com freqüência. O objetivo do estudo foi aplicar o modelo de crenças em saúde (MCS) para explicar este problema, relacionando o comportamento individual às crenças de suscetibilidade, severidade, benefícios e barreiras, e aos estímulos recebidos para adotar a recomendação. MÉTODOS: Por meio de questionário respondido por profissionais de enfermagem de um hospital, foram identificados: a freqüência com que reencaparam agulhas (mês anterior) e as crenças do MCS. Para mensurar as crenças, foram construídas escalas tipo Likert, submetidas à validação de conteúdo (juízes) e de constructo (análise fatorial exploratória) e à análise da confiabilidade (coeficientes alfa de Cronbach e de correlação de duas metades). A relação entre crenças e adesão à recomendação de não reencapar agulhas foi obtida pela análise de regressão. RESULTADOS: Da amostra de profissionais de enfermagem obtida por adesão (n=319), cerca de 75% relataram reencapar agulhas pelo menos alguma vez. Os profissionais de enfermagem que aderiram mais freqüentemente à recomendação de não reencapar agulhas tinham menos de dois anos de experiência profissional, percebiam menor número de barreiras e maior número de benefícios para adotar a recomendação. Esses resultados possibilitaram discutir a reformulação do treinamento oferecido pela instituição hospitalar.

Universal precautions--do Irish anaesthetists comply?

BACKGROUND

Anaesthetists are at high risk from blood-borne pathogens. Universal Precautions (UP) include the routine use of appropriate barrier precautions and techniques to reduce the likelihood of exposure to blood, body fluids and tissues that may contain pathogens. The compliance of Irish anaesthetists with these precautions has not been studied.

AIM

To study the attitudes of Irish anaesthetists to Universal Precautions.

METHOD

A postal questionnaire was sent to 210 anaesthetists currently practising in Ireland. The questionnaire was based on a model used in Australia and New Zealand.

RESULTS

There was a 50% response rate to the survey. Only 15% of respondents had taken a risk history from a patient in the preceding four weeks. Resheathing of needles was commonplace. The effectiveness of hepatitis B immunisation was rarely checked and only 66% of respondents believe implementation of Universal Precautions to be practical.

CONCLUSION

Irish anaesthetists comply poorly with Universal Precautions.

Accidental exposures to blood and other body fluids in a large academic medical center

Healthcare workers' and students' exposures to blood-borne pathogens during a 1-year period (1997) at a large university academic medical center were analyzed. The university health manages the Blood-Borne Pathogen Post-Exposure Control Program at the university and treats all reported exposures of students, faculty, and staff. Comparative exposure rates for all categories of healthcare workers, the work site where injuries occurred, and the circumstances involved in 298 exposure incidents are outlined. A standardized postexposure prophylaxis protocol provides for definition of the health status of all known source patients and assessment of the potential need for treatment of the exposed clinician. Implications of the study for focusing on improvements in training healthcare workers in proper procedures and the use of personal protective equipment in dealing with blood-borne pathogens are discussed.
