Noncompliance with Universal Precautions Policy: why do physicians and nurses recap needles?

Nurses' Body Fluid Exposure Reporting, HIV Testing, and Hepatitis B Vaccination Rates

The purpose of this study was to investigate whether mandatory universal precautions changed nurses' body fluid exposure and reporting rates, hepatitis B vaccination rates, and human immunodeficiency virus (HIV) testing rates. Random cross-sectional surveys of nurses in Tennessee were conducted in 1991 and 1993 (n = 145 in 1991; n = 143 in 1993). The questionnaire in both surveys included frequency of body fluid exposures and reporting in the past year, and whether or not the respondent had received the hepatitis B vaccine or had been HIV tested. Findings indicated that self reported needlestick injuries decreased by 69%, and other sharps injuries decreased by 81%. Only 4.1% of all exposure incidents reported on this anonymous survey were reported to employee health officials, as required. Body fluid exposure incidents were the most common form of exposure (81%) and the most underreported. Hepatitis B vaccinations significantly increased (61.4% to 82.5%), with a nonsignificant increase in HIV testing (47.2% to 55.6%) from 1991 to 1993. Findings of this study suggest that the universal precautions regulatory mandate has been effective in increasing nurses' compliance to universal precautions. Body fluid contacts were significantly underreported and showed no decrease between 1991 and 1993.

Factors Promoting Consistent Adherence to Safe Needle Precautions Among Hospital Workers

Objective:

To examine organizational factors and occupational characteristics associated with adherence to occupational safety guidelines recommending never recapping needles.

Design:

Mail surveys were conducted with healthcare workers (HCWs) and infection control professionals (ICPs).

Setting:

The surveys were conducted at all non-federal general hospitals in Iowa, except one tertiary-care hospital. Survey data were linked to annual survey data of the American Hospital Association (AHA).

Participants:

HCWs were sampled from statewide rosters of physicians, nurses, and laboratory workers in Iowa. Eligible HCWs worked in a setting and position in which they were likely to routinely handle needles. ICPs at all hospitals in the state were surveyed.

Results:

Ninety-nine ICPs responded (79% response rate). AHA data were available for all variables from 84 (85%) of the hospitals. Analyses were based on 1,454 HCWs who identified one of these hospitals as their primary hospital (70% response rate). Analyses were conducted using multiple logistic regression. Positive predictors of consistent adherence included infection control personnel hours per full-time–equivalent employee (odds ratio [OR], 1.03), frequency of standard precautions education (OR, 1.11), facilities providing personal protective equipment (OR, 1.82), facilities using needleless intravenous systems (OR, 1.42), and management support for safety (OR, 1.05). Negative predictors were use of “blood and body fluid precautions” isolation category (OR, 0.74) and increased job demands (OR, 0.90).

Conclusion:

Healthcare organizations can improve staff safety by investing wisely in educational programs regarding approaches to minimize these risks, providing protective equipment, and eliminating the use of blood and body fluid precautions as an isolation policy.

The importance of implementing safe sharps practices in the laboratory setting in Europe

Healthcare workers are at risk of sharps injuries and subsequent infection from more than 40 bloodborne pathogens or species. Hepatitis B Virus (HBV), Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV) together account for the vast majority of cases. The Directive 2010/32/EU “Prevention from sharp injuries in the hospital and healthcare sector”, issued to protect workers from these risks, requires an integrated approach to prevention including awareness-raising, education, training, elimination of unnecessary needles, safe procedures for sharps use and disposal, banning of recapping, vaccination, use of personal protective equipment, provision of safety-engineered devices, and appropriate surveillance, monitoring, response and follow-up.

As laboratories represent a high-risk setting both in the preanalytical and analytical phase, we reviewed accidents and prevention in this setting in the light of the new legislation.

Phlebotomy is the procedure carrying the highest risk of exposure and infection, involved in 30–50% of HIV and HCV cases detected in nationwide systems following accidental blood exposures implemented since the 1990s in Italy and France. In laboratories, problems in the management of sharps containers, recapping, needle disassembly by hand and blood transfer from syringes into tubes were observed and accounted for two-thirds of injuries. These accidents could be reduced through education and monitoring of behaviours, and introduction of medical devices incorporating safety-engineered protection mechanisms with appropriate training. Laboratory staff should be immunized against HBV, and know policies and procedures for the post-exposure management and prophylaxis. The management commitment to safety is crucial to ensure the necessary support to these changes.

Knowledge, attitude and practice towards standard isolation precautions among Iranian medical students

OBJECTIVE

Health care workers especially medical students are at risk of being exposed to blood-borne pathogens. Therefore, the aim of this study was to determine the knowledge, attitude and practice of medical students towards standard isolation precautions (SIP).

METHODS

A standardized questionnaire was completed by 148 medical students from April to July of year 2009 to seek their knowledge, attitude and practice towards standard isolation precautions in a clinical setting at Qazvin University of Medical Sciences, Iran.

RESULTS

The mean score of knowledge, attitude and practice towards standard isolation precautions were 6.8±2.1 (maximum 10), 16.6±4.2 (maximum 20), and 18.05 ± 4.5 (maximum 30) respectively. Significant differences were observed between practice of female and male (P < 0.008) and also knowledge of year 6 and year 7 students (P <0.021).

DISCUSSION

Education on infection control based on standard isolation precaution must be stressed and barriers of appropriate practice must be removed.

Factors influencing nurses' compliance with Standard Precautions in order to avoid occupational exposure to microorganisms: A focus group study

BACKGROUND

Nurses may acquire an infection during the provision of nursing care because of occupational exposure to microorganisms. Relevant literature reports that, compliance with Standard Precautions (a set of guidelines that can protect health care professionals from being exposed to microorganisms) is low among nurses. Additionally, high rates of exposure to microorganisms among nurses via several modes (needlesticks, hand contamination with blood, exposure to air-transmitted microorganisms) occur. The aim of the study was to study the factors that influence nurses' compliance with Standard Precaution in order to avoid occupational exposure to pathogens, by employing a qualitative research design.

METHOD

A focus group approach was used to explore the issue under study. Four focus groups (N = 30) were organised to elicit nurses' perception of the factors that influence their compliance with Standard Precautions. The Health Belief Model (HBM) was used as the theoretical framework and the data were analysed according to predetermined criteria.

RESULTS

Following content analysis, factors that influence nurses' compliance emerged. Most factors could be applied to one of the main domains of the HBM: benefits, barriers, severity, susceptibility, cues to action, and self-efficacy.

CONCLUSIONS

Changing current behavior requires knowledge of the factors that may influence nurses' compliance with Standard Precautions. This knowledge will facilitate in the implementation of programs and preventive actions that contribute in avoiding of occupational exposure.

Perceptions of personal health risks by medical and non-medical workers in a university medical center: a survey study

Background

Health care workers (HCWs) are faced with many work-related choices which may depend on how they perceive risk, such as whether or not to comply with safety regulations. Little research has investigated risk perception in medical workers in comparison with non-medical workers and the extent to which risk perception differs in these groups. The current study thus investigates risk perception of medical and non-medical workers to inform and complement future research on safety compliance. The study has implications for the design of intervention programmes to increase the level of compliance of HCWs.

Methods

A survey study was conducted in which questionnaires were distributed to 6380 HCWs. The questionnaire asked for ratings of risk perception for cold, annual influenza, pandemic influenza, cancer, heart attack and food poisoning. Of 2495 returned questionnaires (response rate: 39%), 61.40% were from medical workers (24.1% of these were from physicians, 39.7% from nurses and 36.2% from paramedics) and 38.60% were from non-medical workers.

Results

Medical workers gave lower risk perception ratings than did non-medical workers for cancer, but not for other health risks. Within the medical workers, physicians rated the risk of getting a cold as higher, but of having a heart attack as lower than did nurses and paramedics; physicians also rated their risk of getting cancer as lower than did nurses. Perceived risk was higher as a function of age for pandemic influenza, cancer and heart attack, but lower for cold and annual influenza. HCWs who lived with a partner and children rated the risk of getting a cold or annual influenza higher than those who lived alone or with a partner only. Full-time HCWs gave lower ratings for annual influenza than did part-time HCWs.

Conclusions

Different base levels of risk perception between medical and non-medical workers need to be taken into account for successful implementation of safety regulations.

Intervention programmes to improve compliance with safety regulations may need to be customized for different groups as a function of how they perceive risk.

Infection control practices among interventional radiologists: results of an online survey

PURPOSE

To assess current infection control practices of interventional radiologists (IRs) in the context of recommendations by the Centers for Disease Control and Prevention and the Occupational Safety and Health Administration.

MATERIALS AND METHODS

From November 2006 to January 2007, members of the Society of Interventional Radiology (SIR) were invited to participate in an anonymous, online infection control questionnaire.

RESULTS

A total of 3,019 SIR members in the United States were contacted via e-mail, and 1,061 (35%) completed the 57-item survey. Of the respondents, 283 (25%) experienced a needlestick injury within the previous year, most often as a result of operator error (76%). Less than 65% reported compliance with annual tuberculosis skin testing; notably, those who received a yearly reminder were much more likely to receive annual testing than those who did not (odds ratio, 19.0; 95% CI, 12.6-28.7; P < .05). During central venous catheter placement, only 56% wore gowns, 50% wore caps, and 54% used full barrier precautions. Only 19% reported routine hand washing between glove applications. More than 40% noted a change in infection control practices within the previous 5 years, citing new hospital guidelines and recommendations by a professional organization as the reasons for change. Only 44% had infection control training at the onset of their practice.

CONCLUSIONS

IRs demonstrate a wide variety of infection control practices that are not in accordance with current guidelines. IRs were most likely to change infection control practice if required to do so by their own hospitals or a professional organization. SIR can play an important role in the prevention of health care-associated infection by reinforcing current infection control guidelines as they pertain to interventional radiology.

Perceptions, attitudes, and behavior towards patient hand hygiene

BACKGROUND

Hand hygiene is the single most important intervention to prevent the spread of health care-associated infection. However, improvement strategies predominantly focus on health care workers with limited emphasis on patient hand hygiene. This study aimed to explore perceptions, attitudes, and self-reported behavior towards patient hand hygiene among clinical ward nurses within an acute hospital environment.

METHODS

A mixed methodologic, descriptive, cross-sectional survey design using questionnaires exploring perceptions, attitudes, and self-reported behavior was used.

RESULTS

Despite clinical ward nurses demonstrating good perceptions and positive attitudes toward patient hand hygiene, they were not found to be independently associated with positive behavior. A positive, modest correlation was found between perceptions and attitudes (P<.001), but a negative, weak correlation was found between perceptions and self-reported behavior (P=.001) and attitudes and self-reported behavior (P<.001).

CONCLUSION

Despite epidemiologic evidence to suggest that hand hygiene is an important part of preventing health care-associated infection, patients are not provided the opportunity to do so. Human behavior is extremely complex and is the consequence of multiple interdependent influences from biology, environment, education, and culture. Major beliefs and barriers that alter nurses' preexisting behavior toward patient hand hygiene must be acknowledged.

[Application and evaluation of a web-based education program on blood-borne infection control for nurses]

PURPOSE

To develop a web-based program on blood-borne infection control and to examine the effect of the newly developed program on perceived threat of diseases, knowledge, preventive health behaviors for blood-borne infections, and incidence rates of accidental needle sticks and other sharp object injuries in nurses.

METHODS

The program was developed through the processes of analysis, design, development, implementation, and evaluation. The research design involved a nonequivalent control group for pretest and posttest experiments. The setting was a 745-bed general hospital located in Korea.

RESULTS

The program was designed and developed after consulting previous studies. After development of the program was completed, it was evaluated and revised by a panel of experts. The total score for perceived threat of diseases, knowledge, preventive health behaviors in the experimental group was significantly higher compared to the control group (p<.05). The incidence rates for needle sticks and other sharp object injuries in the experimental group were significantly lower compared to the control group (p<.05).

CONCLUSION

Application of a Web-based, blood-borne infection control program is effective, and can be expanded to other healthcare workers who also have a high risk of blood-borne infections.

Public attitudes and opinions toward physicians and dentists infected with bloodborne viruses: results of a national survey

BACKGROUND

There has been no recent assessment of public attitudes and opinions concerning risk of bloodborne virus transmission during health care.

METHODS

Seven items in the 2000 annual Healthstyles survey were used to assess current attitudes and opinions about health care providers infected with human immunodeficiency virus (HIV) and the risk of bloodborne virus transmission during health care in a sample of approximately 3000 US households.

RESULTS

Of the 2353 respondents, 89% agreed that they want to know whether their doctor or dentist is infected with HIV; 82% agreed that disclosure of HBV or HCV infection in a provider should be mandatory. However, 47% did not believe that HIV-infected doctors were more likely to infect patients than doctors infected with HBV or HCV. Opinions were divided on whether HIV-infected providers should be able to care for patients as long as they use good infection control: only 38% thought that infected providers should be allowed to provide patient care.

CONCLUSIONS

These findings suggest that improved public education and risk communication on health care-associated bloodborne infections is needed.

Protecting health care workers from SARS and other respiratory pathogens: organizational and individual factors that affect adherence to infection control guidelines

BACKGROUND

Traditional infection control policies have focused on engineering controls, specific protocols, and personal protective equipment (PPE). In light of the variable success in protecting health care workers (HCWs) from Severe Acute Respiratory Syndrome (SARS) in 2003, organizational and individual factors related to self-protective behavior in health care settings may also play an important role.

METHODS

A critical review of the literature was conducted, directed at understanding what organizational and individual factors are important in protecting HCWs from infectious diseases at work.

RESULTS

Organizational factors, such as a positive safety climate, have been associated with increased HCW adherence to universal precautions. There is some evidence that appropriate training of HCWs could be effective in changing HCW behavior if appropriate follow-up is applied. Very little research into these factors has been conducted with regard to preventing exposures to respiratory tract pathogens, but there was evidence from the SARS outbreaks that training programs and the availability of adequate PPE were associated with a decrease risk of infection.

CONCLUSION

Variations in organizational and individual factors can explain much of the variations in self-protective behavior in health care settings. It is likely that these factors were also important determinants during the SARS outbreaks, but they have not been extensively studied.

Knowledge, practice and attitude towards standard isolation precautions in Iranian medical students

Medical students are at high risk of being exposed to blood-borne pathogens. The aim of this study was to identify the levels of knowledge, attitude and practice of medical students regarding standard isolation precautions in Iran. A questionnaire was filled out by 468 medical students in their fifth to seventh year of study. Their mean knowledge, attitude and practice levels of standard isolation precautions were 6.1+/-1.5 (maximum possible score 9), 32.3+/-3.5 (out of 45), and 2.3+/-1.6 (out of 9), respectively. Statistically significant positive correlations were observed between knowledge and attitude, knowledge and practice, and practice and attitude. Ninety percent of medical students in Shiraz had received no education of standard isolation precautions, and 75% of respondents wanted more education on standard isolation precautions. Education on infection control issues should not only be focused on healthcare workers, but should also include medical students.

Critical incidents of nonadherence with standard precautions guidelines among community hospital-based health care workers

OBJECTIVE

To identify, categorize, and assess critical incidents of nonadherence to standard precautions.

DESIGN

Qualitative and quantitative analysis of a written, mail-out survey.

SETTING

Community hospitals.

PARTICIPANTS

Statewide stratified random sample of community hospital-based health care workers at risk for blood exposure. MAIN VARIABLE: Responses to the question: "Think of an incident during the past year when you didn't adhere to universal precautions. Please describe the situation and why you didn't adhere."

RESULTS

Reasons given for not using precautions included: belief that stopping to use standard precautions would have put the patient at risk (22%); using precautions would have interfered with patient care (20%); precautions were not warranted in a specific situation (14%); did not anticipate the potential for exposure (14%); and high job demands that had caused respondent to be in a hurry (11%). Less often, equipment was not available (7%), respondent forgot (6%), respondent thought that the patient did not pose a risk (4%), or the available equipment was not effective (3%). In terms of overall exposure rates, 34% of those who described an incident had experienced a sharps injury during the previous 3 months and 42% had experienced a mucocutaneous exposure. In terms of overall nonadherence, 44% wore gloves less than 100% of the time, while 61% washed their hands less than 100% of the time. Needlestick injuries were lowest among those who had forgotten to use precautions, while mucocutaneous exposures were highest among those who had not anticipated potential exposure while performing the task. Failure to wear gloves routinely was highest among those who said that following precautions interfered with their ability to provide care and among those who believed a particular patient to be low risk; failure to wash hands routinely was also highest among the latter group and lowest among those who said necessary equipment was not available.

CONCLUSIONS

Using specific information about local incidents of nonadherence to standard precautions may enhance training, especially if the program identifies incidents of unanticipated exposure and helps workers plan for them in the future. Closer examination of job demands and responsibilities that interfere with standard precautions may increase the likelihood of adherence.

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.

Mismanaging the gift of life: noncompliance in the context of adult stem cell transplantation

In this paper, we address the issue of noncompliance with medical regimens in adult stem cell transplant patients. We review the definition, prevalence, and consequences of noncompliance and address whether or not we should alter our medical decision-making with regard to stem cell transplantation based on patient noncompliance. We discuss how the health care team should handle noncompliance issues and propose clinical guidelines for stem cell transplant programs to consider regarding evaluation and management of medical compliance.

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.

Monitoring adherence to Standard Precautions

BACKGROUND

Health care workers (HCWs) do not consistently follow Standard Precautions (SP). This is a serious problem because inadequate compliance is associated with increased blood exposure thus predisposing HCWs to bloodborne pathogen transmission.

METHODS

The primary goal of this study was to identify institutional factors associated with adequacy of HCW training to monitor coworkers' adherence to SP. Surveys were sent to all community hospital infection control practitioners (ICPs) in Iowa and Virginia. ICPs indicated on a 5-point Likert scale, ranging from strongly disagree to strongly agree, their assessment of HCW training adequacy. Data from another statewide survey of HCWs in Iowa were assessed to validate this outcome measure. Multiple logistic regression models were developed to identify predictors of assessed training adequacy. Independent variables included methods of education, training, approaches to SP compliance assessment, provision of SP reinforcement by clinical leaders, and organizational data.

RESULTS

A total of 149 institutions (62%) participated. Models of training program adequacy varied across occupations. Management commitment to SP training programs, leadership support, frequency of providing bloodborne pathogen information, and safety climate were important institutional predictors of assessed adequacy of training. The outcome was validated by demonstrating an association between the ICPs' assessment of HCW training and workers who reported having sufficient information to comply with SP (P <.05).

CONCLUSIONS

Institutional safety climate, leadership support, and frequency of education play an important role in HCWs' training adequacy to monitor coworkers' adherence to SP. Occupational groups should be considered independently when strategies are developed to increase compliance. Interventions based on modifiable factors identified by this study may reduce bloodborne pathogen exposure among HCWs.

The impact of multifocused interventions on sharps injury rates at an acute-care hospital

OBJECTIVE

To determine the impact of a multifocused interventional program on sharps injury rates.

DESIGN

Sharps injury data were collected prospectively over a 9-year period (1990-1998). Pre- and postinterventional rates were compared after the implementation of sharps injury prevention interventions, which consisted of administrative, work-practice, and engineering controls (ie, the introduction of an anti-needlestick intravenous catheter and a new sharps disposal system).

SETTING

Sharps injury data were collected from healthcare workers employed by a mid-sized, acute-care community hospital.

RESULTS

Preinterventional annual sharps injury incidence rates decreased significantly from 82 sharps injuries/1,000 worked full-time-equivalent employees (WFTE) to 24 sharps injuries/1,000 WFTE employees postintervention (P<.0001), representing a 70% decline in incidence rate overall. Over the course of the study, the incidence rate for sharps injuries related to intravenous lines declined by 93%, hollow-bore needlesticks decreased by 75%, and non-hollow-bore injuries decreased by 25%.

CONCLUSION

The implementation of a multifocused interventional program led to a significant and sustained decrease in the overall rate of sharps injuries in hospital-based healthcare workers.

Nurses failure to appreciate the risks of infection due to needle stick accidents: a hospital based survey

One of the most important occupational risks to healthcare workers is exposure is to blood-borne viruses. This study examined nurses' perceptions of risk of contracting infection following single or multiple exposure to blood or body fluids. Two hundred and ninety nurses were surveyed using a questionnaire. One hundred and thirty-three responded; 85 worked in higher risk areas (ITU, Haematology, Haemodialysis and Neonatal Surgical Units) (Group A) and 48 worked in lower risk areas (medical wards, an orthopaedic and an ENT ward) (Group B). Forty-nine percent of subjects from group A and 60% of subjects from Group B believed that a needle stick injury with a needle contaminated with infected blood was an unlikely source of infection. Fifteen percent from group A and 20% from group B thought that infection with a blood-borne virus following a needle stick injury contaminated with Human Immunodeficiency Virus (HIV) infected blood was very unlikely. Twelve percent from group A and 10% from Group B did not know whether resheathing needles between use can provide protection against HIV. Sixty-seven percent from group A and 71% from group B disagreed with the statement that nurses are at higher risk of exposure to HIV/HBV than the other healthcare workers. Thirteen percent from group A and 5% from group B agreed with the statement, whereas 8% from group A and 5% from group B thought that nurses are at less risk. Only 22% from group A and 23% from group B would take more precautions if they knew that the patient had HIV/HBV infection, whilst 11% and 8% respectively admitted that they would take special precautions only when the patient has clinical symptoms of HIV/HBV infection. The findings suggest that these nurses would benefit from further education regarding infection from blood-borne viruses.

Universal precautions compliance and exposure frequency to patient body fluids in nurses employed by urban and rural health care agencies

Previous studies have suggested that health care workers may differ with respect to universal precautions knowledge, compliance, practice setting barriers, or exposure to patient body fluids in rural and urban areas. The purpose of this study was to determine whether or not there are rural/urban differences in the degree of precaution taken by health care workers to prevent the spread of blood borne pathogens, specifically human immunodeficiency virus (HIV) and hepatitis B virus (HBV). A random sample of rural and urban registered and licensed practical nurses in Tennessee was surveyed. The respondents completed two instruments that assessed self-reported universal precautions knowledge, precautions, and practice barriers. No measurable differences in universal precautions knowledge, compliance, or barrier scores between the two groups were found; yet rural nurses were 2.7 times as likely to be exposed to patient body fluids than urban nurses (P < 0.005). The conclusion was that rural nurses were as experienced and as knowledgeable about universal precaution techniques as their urban peers, but their knowledge was not translated into practice to the same degree. Two possible explanations offered are (1) rural nurses are more likely to be acquainted with, and thus trusting of, their patients, and (2) the lower seroprevalence of human immunodefiency virus and hepatitis B virus in rural areas may lead to complacency.

[The nursing team and occupational accidents with potentially contaminated material in the era of HIV]

This investigation was carried out in order to: identify the occurrence of professional accidents with perforate cutting potentially contaminated material among nurses and nursing auxiliaries that work in a general teaching hospital in the interior of the state of São Paulo. The other objectives were: to associate the occurrence of accident with the professional category and period of work; to identify the type of perforate cutting material most involved in accidents, to identify the attitudes taken by the person accidented. The data were collected on individual interview based on a structured formulary in which the following information was registered: the probable reason of accident, how long the professional has been working on such function, the material involved in the accident, the actions taken after the accident. It was evidenced that the Standard Precautions or the Universal Precautions as they used used to be nominated are not being used as they should be. Such attitude brings risks to the nursing team. We think that this team needs specific orientations through continuing education concerning the theme.

Bloodborne pathogens and procedure safety in interventional radiology

Concern about possible transmission of bloodborne pathogens during medical procedures is growing among patients and healthcare workers alike. This fear has primarily been focused on nosocomial transmission of human immunodeficiency virus (HIV), but other bloodborne infectious agents may also be transmitted during procedures. Chief among these are the hepatitis viruses, particularly hepatitis B virus (HBV) and hepatitis C virus (HCV), both of which are significantly more widespread than HIV. Although radiology is not traditionally thought of as a field with significant risk for exposure to or transmission of pathogens, the expanding role of interventional procedures in recent years belies that perception. The potential for exposure to blood or other possibly infectious material exists in virtually any invasive radiological procedure, from arteriography to image-guided biopsy. Fortunately, the risk of such exposure is low, and the risk of actual transmission of a bloodborne pathogen, whether from patient to healthcare worker or vice versa, is even lower. Nevertheless, it is important for all radiologists who perform invasive procedures to be aware of these risks and to observe pertinent safety and infection control recommendations. This article will review these topics.

Compliance with gloving in anesthesia: an observational study of gloving practice at induction of general anesthesia

STUDY OBJECTIVE

To gather direct observational data on anesthesiologists' compliance with universal precautions' gloving standards during induction of general anesthesia.

DESIGN

Prospective, observational study.

SETTING

Operating theaters of an Israeli government teaching hospital.

SUBJECTS

Over a four-month period, all "first case of the day" general anesthetics were observed to determine if the anesthesiologist directly administering patient care wore gloves during the period of anesthetic induction. All anesthesia department members were observed and none was aware of the ongoing study.

MEASUREMENTS AND MAIN RESULTS

Resident anesthesiologists were found to be more compliant with gloving policy than their attendings (61.8% vs. 33.7%, p < 0.0001). However, the lower compliance among the attendings was entirely attributable to the most senior staff members (over age 55 years) whose compliance rate was 11.5% versus 55.6% for attending staff below age 55 years (p < 0.0001). Departmental compliance as a whole was 49.6%. Compliance in pediatric cases averaged 10% and was equally poor among all department staff.

CONCLUSIONS

Although glove use remains inconsistent, in less than one and one half years since institution of a departmental gloving policy, a substantial degree of compliance was achieved. Nevertheless, further efforts are still needed to improve compliance with universal precautions. In this study, glove use was particularly deficient in pediatric cases and among senior staff aged 55 years and older. Pinpointing specific areas of greatest deficiency may prove useful in guiding additional efforts to improve compliance with universal precautions.

Percutaneous blood exposure among Danish doctors: exposure mechanisms and strategies for prevention

The objective of this study was to describe the mechanisms of percutaneous blood exposure (PCE) among doctors and discuss rational strategies for prevention. Data were obtained as part of a nation-wide questionnaire survey of occupational blood exposure among hospital employed doctors in Denmark. The doctors were asked to describe their most recent PCE, if any, within the previous 3 months. Detailed information on the instruments, procedures, circumstances and mechanisms that caused the PCE was obtained. Of 9375 doctors, 6256 (67%) responded, and 6005 questionnaires were eligible for analysis. Of 971 described PCE the majority were caused by suture needles (n = 483), i.v.-catheter-stylets (n = 94), injection needles (n = 75), phlebotomy needles (n = 53), scalpels (n = 45), arterial blood sample needles (n = 41) and bone fragments (n = 23). Inattentiveness was the most common cause, contributing to 30.5% of all PCE. Use of fingers rather than instruments was a major cause of injury in surgical specialities and was a contributing cause of 36.9% PCE on suture needles. Common contributing causes when fingers were used (n = 199) were poor space in (30.2%) or view of (18.6%) the operation field. It was often argued that instruments were not practical to use or might harm the tissue. Of 689 PCE in surgical specialties, 17.4% were inflicted by colleagues. Up to 53.3% of PCE on hollow-bore needles could be attributed to unsafe routines like recapping only, but other mechanisms like sudden patient movements and 'acute situation' were common, especially in the case of PCE on i.v.-catheter-stylets. It is concluded that the exposure mechanisms of PCE reflect both unsafe routines, difficult working conditions and unsafe devices. Education in safer working routines are needed in all specialties. Introduction of safer devices should have a high priority in surgical specialties, and should be considered in non-surgical specialties too.

Issues complicating the implementation of postexposure prophylaxis

Occupational exposures to blood-borne pathogens occur regularly in diverse settings and involve multiple groups of healthcare workers. Current compliance of healthcare workers with behavioral controls is poor, and additional engineering and work-practice controls for exposure prevention are inadequate and/or underutilized. Barriers to effective postexposure management include deficient knowledge and fear and denial among healthcare workers, the diverse risks associated with different exposures, the costs and personnel necessary for providing exposure management 24 hours a day, variable levels of expertise in postexposure prophylaxis strategies, and administrative requirements for standardized policies and procedures. In the current environment, healthcare institutions are largely ill equipped to provide timely and effective postexposure prophylaxis. Widespread worker education, simplified reporting mechanisms, and availability of prompt source and worker testing along with timely, free postexposure prophylaxis is central to an institution's postexposure program. Postexposure management programs should be comprehensive and provide standardized procedures, expand workers' access to postexposure prophylaxis by establishing responsible parties in diverse areas, disseminate program information to all workers, and ensure confidentiality in the care and follow-up of exposed workers. To implement such programs, it may be necessary to merge resources and link local management of exposures with regional expertise to provide up-to-date counseling in a rapidly changing field. Careful surveillance of occupational exposures is essential to evaluate program efficacy, direct prevention efforts, and to determine necessary resources to ensure continued successful delivery of postexposure prophylaxis.

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

In an attempt to document blood exposure incidents and compliance with recommended serological investigations, universal precautions and incident reporting routines, data was collected from occupational injury reports during a two-year period. In addition, a sample of healthcare workers (HCWs) answered a questionnaire about blood tests and work routines. In a third part of the study some HCWs were asked about the type and actual frequency of incidents, together with the number of reported incidents during the two-year study period. Of a total of 473 reported occupational blood exposures, the majority came from nurses and the minority from physicians. Most reported incidents occurred on hospital wards. The most common incidents were needlestick injuries, and 35% occurred when the needle was recapped. Medical laboratory technicians (MLT) reported significantly more mucocutaneous incidents than other professionals (P < 0.01). In 10% of the incidents, the patient had a known blood-borne infection. Serological investigations post-exposure varied among professional groups, and 35% were not tested. No seroconversion was shown in the HCWs tested. In the third part of the study, respondents recalled 1180 incidents, although only 9% of these had been reported. The majority occurred in operating theatres, and in connection with anaesthesia. There was a significant difference (P < 0.001) between the different professional groups with regard to the frequency of incident reporting. Physicians reported only 3% and MLTs 36% of the incidents. Eighty-one percent believed that the accident could have been avoided. Despite knowledge of universal precautions, professionals continue to behave in a risky manner, which can result in blood exposure incidents.

Compliance with universal precautions among physicians

This study characterized and assessed self-reported levels of compliance with universal precautions (UP) among hospital-based physicians, and determined significant factors associated with both compliance and noncompliance. The physicians (n = 322) were a subgroup of a larger study population of hospital-based health care workers recruited from three geographically distinct locations (n = 1746), and were surveyed using a detailed confidential questionnaire that assessed personal, work-related, and organizational factors. Compliance with UP was measured through 11 items that examined how often physicians followed specific recommended work practices. Compliance was found to vary among the 11 items: they were high for certain activities (eg, glove use, 94%; disposal of sharps, 92%) and low for others (eg, wearing protective clothing, 55%; not recapping needles, 56%). Compliance with all items was low (31% to 38%). Stepwise logistic regression revealed that noncompliant physicians were likely to be age 37 or older, to report high work stress, and to perceive a conflict of interest between providing patient care and protecting themselves. Compliant physicians were more likely to be knowledgeable and to have been trained in universal precautions, to perceive protective measures as being effective, and to perceive an organizational commitment to safety.

A critical review of the literature on sharps injuries: epidemiology, management of exposures and prevention

This article reviews the literature related to the epidemiology, prevention and management of sharps injuries in health care workers, particularly nurses, and the subsequent risk of harm. The studies are reviewed chronologically, beginning with the efforts to reduce sharps injuries by changing behaviours, followed by the introduction of barriers to protect the caregiver, and finally, the engineering of safer products. Initial efforts to prevent sharps injuries focused on placing rigid, disposal containers at the site where sharps were used and instructing health care workers to refrain form the practice of recapping. When these interventions were shown to alter the type, but not the overall number, of sharps injuries, alternative measures were sought. This search intensified with the increasing evidence of the small, but measurable, risk of the transmission of human immunodeficiency virus from sharps injuries. The current knowledge of the factors related to sharps injuries has been collected primarily through retrospective surveillance. This surveillance has been conducted primarily in hospital settings and has focused on the type of sharp and the purpose for which it was used rather than prospective research. Research is now needed to elucidate the organizational and behavioural factors leading to sharps injury both within the hospital as well as other health care settings. The implications for nursing practice are discussed.

The use of a ward-based educational teaching package to enhance nurses' compliance with infection control procedures

Obtaining study leave is becoming difficult for clinical nurses in the current economic climate, but the need to develop new clinical skills and to maintain existing good practice remains of prime importance to patient care and will become mandatory with the advent of post-registration education and practice (PREP) in the UK. The ward is widely acknowledged as the best venue for learning clinical skills by nurse educationalists and for many nurses is the preferred learning environment. The feasibility of using a ward-based teaching package to enhance nurses' compliance with key infection control precautions (hand decontamination, the use of gloves and the safe handling and disposal of sharp instruments) was tested in a quasi-experimental research study conducted on matched surgical wards in a teaching hospital, controlling for variables likely to influence performance (knowledge, availability of resources to perform infection control, previous opportunity to develop infection control expertise and nursing workload). Nurses on two wards received the intervention (experimental group). The remaining wards, which received no intervention, operated as controls. The ward-based sessions consisted of a carefully planned sequence of theory and practical demonstration delivered to qualified nurses in the clinical environment at convenient times selected by the ward managers. Performance of infection control precautions was audited before the intervention and 3 months afterwards. The sessions were well evaluated and the clinical environment was considered suitable for teaching by the nurses, but heavy and unpredictable workload prevented the teaching programme from being implemented as planned. The analysis of covariance failed to detect any changes in performance between nurses in the control and experimental groups. The implications of the study findings are discussed to help develop creative new ways of strengthening ward-based educational programmes.

Nurses' compliance with universal precautions before and after implementation of OSHA regulations

The principal objective of this study was to investigate whether or not nurses' compliance with universal precautions procedures improved after the mandatory Occupational Safety and Health Administration regulations were implemented in 1992. Two random samples of registered nurses and licensed practical nurses registered in Tennessee responded to survey questionnaires measuring universal precautions compliance and practice barriers to compliance in 1991 and 1993 (n = 306). The 1993 sample of nurses reported significantly greater compliance with universal precautions (p < 0.001) than the 1991 sample. The most noteworthy improvement between the 1991 and the 1993 groups was a significant increase in compliance for patients described as HIV/HBV-status unknown and HIV/HBV-negative (p < 0.001). Practice barriers hindering compliance with universal precautions decreased significantly (p < 0.001) in the 1991-1993 time frame. Problematic practice barriers identified in both groups were needle recapping, preference for isolation door signs, and concerns about offending patients and visitors.

The routine wearing of gloves: impact on the frequency of needlestick and percutaneous injury and on surface contamination in the operating room

The impact of wearing gloves on surface contamination and on the incidence of percutaneous injury were prospectively compared for two 4-mo periods in a single anesthesia department. Period I was immediately prior to the institution of mandatory glove wearing, and Period II followed a 1-mo adjustment period of mandatory glove use. Recording of all needlestick and other percutaneous injuries was performed on an ongoing basis, and incident reporting was actively and regularly solicited. During the final week of each period, 12 specific sites at each of nine anesthetizing locations were tested for occult blood. The incidence of needlestick injury was 0.28% for Period I versus 0.10% for Period II (P = 0.10) and the incidence for all percutaneous injuries was 0.60% for Period I and 0.27% for Period II (P = 0.06). If the one needlestick that occurred during noncompliance with gloving during Period II is eliminated, then there was a significant reduction in both needlestick and overall percutaneous injury (P < 0.05). Of 109 operating room sites, 42.2% were contaminated after Period I versus 31.2% after Period II (P = 0.07). The implementation of a mandatory glove use policy was associated with nonsignificant trends toward reduction in the incidence of needlestick and other percutaneous injury and in the level of surface contamination in the anesthesia workplace. Compliance with glove use resulted in a significant reduction in needlestick injury and overall percutaneous injuries.

A work-systems analysis of compliance with universal precautions among health care workers

Universal precautions are work practices designed to protect health care workers from occupational exposure to HIV and other bloodborne pathogens. However, despite aggressive dissemination efforts by CDC and regulatory action by OSHA, compliance remains less than satisfactory. This article argues that the minimization of risk from bloodborne pathogens requires a multilevel or work-systems perspective that considers individual, job/task, and environmental/organizational factors. The available literature on universal precautions suggests the potential of such an approach and provides insight into the limited success of current worker-focused mitigation efforts. In particular, specific opportunities exist to develop and apply engineering controls, to improve the design and organization of jobs and tasks, and to create organizations that facilitate and reinforce safe behavior.

Nurses' infection-control practice: hand decontamination, the use of gloves and sharp instruments

Infection is an acknowledged hospital problem. Micro-organisms are disseminated mainly via hands but there is evidence that hand decontamination, the most important means of prevention, is performed too seldom, and not always after activities likely to result in heavy contamination. Nurses themselves are exposed to risks of infection, chiefly through contact with blood and body fluids, yet it has also been reported that gloves are not always worn during contact with patients' secretions and that the handling and disposal of sharp instruments may be performed unsafely. The study reported in this paper documents nursing behaviour in relation to hand decontamination, the use of gloves and sharps, taking into consideration a number of variables which could influence practice: availability of the expertise afforded by an infection-control nurse, clinical setting, nursing workload, knowledge and the resources available to control infection. Hands were decontaminated after 28.78% of patient contacts. Hands were decontaminated after 49.85% of activities likely to result in heavy contamination. Performance was related to nursing workload and the availability of hand decontaminating agents, especially when the nurses became busy. Use of gloves when they were available also proved good, with little evidence of wasteful use. The handling and disposal of sharps were commendable for most subjects but a few grossly unsafe incidents were nevertheless witnessed, apparently not associated with any of the variables examined.

Risk taking by health care workers

HEALTH CARE WORKERS (HCWs) are at risk for acquiring infections such as human immunodeficiency virus, hepatitis B virus, hepatitis C, and tuberculosis from blood and body fluids. The Centers for Disease Control established guidelines known as universal precautions (UPs) to prevent transmission of blood-borne pathogens in hospital settings, but UPs are not universally followed. CNSs are in a unique position to enhance the practice of UPs and decrease the HCW's risk-taking behavior. CNSs need to identify risk-taking behaviors and help HCWs make the right decision in risky situations. Reasons cited for noncompliance with UPs were habit, forgetfulness, influence of the nurse manager, and perceptions that barrier precautions hinder the ability to perform procedures successfully. Suggestions for improving compliance with UPs were better enforcement of guidelines, a policy mandating compliance, easy and available access to supplies, replacement of hazardous devices with safer ones, and discussion with HCWs on decision making in risky situations. CNSs possess the credibility in the clinical arena to effect change through clinical expertise, role modeling, and collaboration with HCWs.

Injury prevention in anesthesiology

Anesthesia personnel routinely perform procedures that put them at risk for contact with blood and body fluids. Some of these exposures are to skin and mucous membranes; many are percutaneous injuries associated with the frequent use of needled devices. The high risk in anesthesia procedures for contact with infected body fluids is associated with a high incidence rate of actual infection with bloodborne pathogens.

G. Adesão às precauções universais: uma análise do comportamento de equipe de enfermagem

A possibilidade de aquisição do vírus de imunodeficiência humana (HIV) por profissionais de saúde tornou mais preocupante a questão dos riscos ocupacionais. As precauções universais (PU) surgiram como tentativa de aumentar a segurança do profissional de saúde. No entanto, existe certa resistência por parte dos profissionais de saúde em adotar as medidas de proteção. Os objetivos deste estudo são: 1. obter um indicador da adesão da equipe de enfermagem de um hospital geral de São Paulo às precauções universais, 2. identificar a percepção dos riscos e os conhecimentos que os profissionais possuem sobre as PU; e 3. apresentar e discutir hipóteses explicativas do comportamento de não-adesão.

Compliance with universal precautions among health care workers at three regional hospitals

OBJECTIVE

To assess and characterize self-reported levels of compliance with universal precautions among hospital-based health care workers and to determine correlates of compliance.

DESIGN

Confidential questionnaire survey of 1716 hospital-based health care workers.

PARTICIPANTS

Participants were recruited from three geographically distinct hospitals. A stratified convenience sample of physicians, nurses, technicians, and phlebotomists working in emergency, surgery, critical care, and laboratory departments was selected from employment lists to receive the survey instrument. All participants had direct contact with either patients or patient specimens.

RESULTS

For this study, overall compliance was defined as "always" or "often" adhering to the desired protective behavior. Eleven different items composed the overall compliance scale. Compliance rates varied among the 11 items, from extremely high for certain activities (e.g., glove use, 97%; disposal of sharps, 95%) to low for others (e.g., wearing protective outer clothing, 62%; wearing eye protection, 63%). Compliance was strongly correlated with several key factors: (1) perceived organizational commitment to safety, (2) perceived conflict of interest between workers' need to protect themselves and their need to provide medical care to patients; (3) risk-taking personality; (4) perception of risk; (5) knowledge regarding routes of HIV transmission; and (6) training in universal precautions. Compliance rates were associated with some demographic characteristics: female workers had higher overall compliance scores than did male workers (25% of female and 19% of male respondents circled "always" or "often" on each of the 11 items, p < 0.05); and overall compliance scores were highest for nurses, intermediate for technicians, and lowest for physicians. Overall compliance scores were higher for the mid-Atlantic respondents (28%) than for those from the Southwest (20%) or Midwest (20%, p = 0.001).

CONCLUSIONS

This study supports earlier findings regarding several compliance correlates (perception of risk, knowledge of universal precautions), but it also identifies important new variables, such as the organizational safety climate and perceived conflict of interest. Several modifiable variables were identified, and intervention programs that address as many of these factors as possible will probably succeed in facilitating employee compliance.
