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

Development and Validation of the Needlestick Injury Prevention (N-SIP) Module

INTRODUCTION

Needlestick injuries (NSIs) pose a significant occupational hazard to healthcare workers (HCWs), with potential risks of exposure to bloodborne pathogens. The development of effective training modules is crucial to addressing NSI prevention and enhancing HCWs' knowledge and risk perception. This study aims to develop and validate the Needlestick Injury Prevention Module (N-SIP) using the ADDIE model (Florida State University, FL), which stands for Analysis, Design, Development, Implementation, and Evaluation, to improve NSI-related knowledge and risk perception among House Officers (HOs) in healthcare settings.

METHODS

The study utilized approaches comprising literature review, module development using the ADDIE model, content validation by experts, and face validation among HOs. The N-SIP module addressed various aspects of NSI prevention, including background information, bloodborne viral infections, infection prevention practices, and occupational safety. The evaluation involved content validation by expert panels and face validation by HOs.

RESULTS

The content validity of the N-SIP module was rigorously evaluated through expert review and validation by subject matter experts and HOs. The experts' feedback ensured the quality, relevance, and comprehensiveness of the module's instructional materials. Furthermore, face validity was assessed among HOs to ensure the module's clarity, appropriateness, and perceived effectiveness in addressing NSI prevention. The positive response from HOs indicated favorable perceptions of the module's content and instructional design, affirming its potential to effectively enhance perceptions related to NSI prevention among HCWs.

CONCLUSION

The development and evaluation of the N-SIP represent a significant advancement in addressing NSIs among HCWs. Through a structured approach informed by the ADDIE model, the N-SIP module offers a comprehensive and tailored learning experience aimed at enhancing NSI-related knowledge and risk perception among HOs. The study findings underscore the importance of effective training interventions in promoting a culture of safety and reducing occupational hazards in healthcare settings.

The Epidemiology of Needlestick and Sharp Injuries Among Healthcare Workers in a Secondary Care Hospital in Saudi Arabia: A Retrospective Study

Introduction Needlestick and sharp injuries (NSI) continue to pose a significant risk for healthcare workers (HCWs) at their workplace. The incidence rate of NSI in hospitals depends on multiple risk factors. This study aimed to analyze the epidemiological characteristics of NSI among HCWs and the risk factors influencing NSI rates and to provide further direction for NSI prevention in secondary care hospitals. Methods This study included all the NSI cases reported by HCWs in King Abdul Aziz Hospital, Makkah from 2005 to 2017. All the cases were recorded in the Exposure Prevention Information Network (EPINet™) database (International Healthcare Worker Safety Center, University of Virginia, Charlottesville, USA). The study was executed by using data loaded in the EPINet™ Program, the hospital electronic recording system Medica Plus, and analyzed by the Statistical Package for the Social Sciences program (SPSS Inc. Released 2007. SPSS for Windows, Version 15.0. Chicago, SPSS Inc.). Results During the period of study, 524 NSI cases were reported. The mean incidence rate per 100 occupied beds with 95% CI was 25.43 (22.05-28.81) and a statistically insignificant decline in NSI incidence rate was observed from 2005 to 2017. The maximal annual incidence rate (35.63 per 100 occupied beds) was registered in 2010 and the minimal value (14.84 per 100 occupied beds) in 2013. Injuries were mainly reported in patient rooms/wards (30.2%) and most frequently by nurses (56.1%). The mean of incident reporting within 24 hours was 74.0, 95% CI (67.19-80.73). This rate showed a statistically significant (p=0.01) increasing trend of 5.0% per annum. The mean of identified source patients - 83.5, 95% CI (79.13- 87.23) - possessed an annual 2.1% rise during 2005-2017 which was statistically insignificant (p=0.7). Cases occurred after the use/before disposal of items in 45.0% of cases and during the use of items in 44.7%. Hollow-bore needles caused injuries in 46.5% of incidents. Blood sample taking - 23.2% and IV or arterial line insertion/removal/manipulation (19.1%) - presented exposure-prone procedures posing the highest risk. Conclusions The results of this study revealed a high rate of NSI in the hospital. NSI rate in hospitals was impacted by a group of related risk factors, particularly, the location of risk (patient room/ward, intensive care unit (ICU), and emergency room (ER) depending on job intensity, the kind and frequency of exposure-prone procedures (blood sample taking, IV or arterial line insertion/removal/manipulation) and handling of hollow-bore and solid needle connected to the main healthcare professional group at risk (nurses). Future direction in NSI prevention requires a complex approach of continuous staff education along with the usage of devices with safety features.

Status of waste disposal of sharps outside medical institutions for patients with diabetes: A systematic review

OBJECTIVES

As the number of people with diabetes increases, so does the amount of household-generated sharp waste, and incorrect sharp disposal methods can expose the public to needle stick injuries This systematic study assesses the relevant factors and current situation of the disposal of sharp waste in diabetes patients.

METHODS

In this review, our study comprehensively searched PubMed, MEDLINE, Cochrane Library, EMBASE, Web of Science, and China Biomedical, Wanfang, and CNKI for the concepts of "sharps waste disposal" and "diabetes".

RESULT

In 12 identified articles, there are 4155 patients with diabetes. The findings highlight that diabetic patients have a positive attitude towards sharps waste disposal, but lack knowledge and practice of sharps waste disposal, and need to take appropriate measures to improve the rate of proper waste disposal before and during use. Patients with longer duration of diabetes are more likely to engage in inappropriate sharps disposal behaviors.

CONCLUSIONS

The findings emphasize that the majority of diabetic patients are unable to handle sharps safely, so more research is needed to find factors associated with sharps waste disposal in diabetic patients and to focus on sharps waste disposal behaviors in patients with longer duration of disease in future clinical practice.

Improved syringe disposal practices associated with unsanctioned safe consumption site use: A cohort study of people who inject drugs in the United States

BACKGROUND

Community opposition to safe consumption sites often centers around improper syringe disposal. People are concerned these sites might attract people who inject drugs to the neighborhood, which might in turn lead to more used syringes left in public settings.

METHODS

We evaluated an unsanctioned safe consumption site in an undisclosed United States city in 2018-2020 to assess whether use of the site was associated with improper syringe disposal practices. We recruited people who inject drugs (N=494) using targeted sampling methods, and interviewed participants at baseline, 6 months, and 12 months. We employed a quasi-experimental design involving inverse probability of treatment weighting using propensity scores. We used generalized estimating equations and Poisson models to calculate relative risk and incidence rate ratios of improper syringe disposal.

RESULTS

The risk of any improper syringe disposal was comparable among people who used and did not use the unsanctioned safe consumption site in prior 30 days (relative risk 1.03; 95% confidence interval=0.53, 1.17). The rate of improperly disposed syringes per number of injections in prior 30 days was significantly lower among people who had used the unsanctioned safe consumption site during the same period (incident rate ratio 0.42; 95% confidence interval=0.18, 0.88).

CONCLUSION

When people used this unsanctioned safe consumption site, they disposed of significantly fewer syringes in public places, including streets, sidewalks, parks, or parking lots, than people not using the site. This study helps allay concerns that implementing safe consumption sites in the US would lead to increases in improperly disposed syringes.

Sharps Injuries in the Home Health Care Setting

Home health care nurses are at risk of needle-sticks and blood exposures, yet few studies have been conducted related to such exposures in the home health care setting. This article describes a cross sectional prevalence pilot study of needle-sticks and blood exposures conducted among three home health care agencies in the San Francisco Bay area. Needlestick and blood exposure reports from 1993 to 1996 were submitted from three home health care agencies. The exposures were categorized using an existing categorization system and compiled into a composite report. A total of 52 exposures occurred; nurses sustained 92% of exposures. Twenty-three percent occurred before, during, or after needle disposal; 17% from manipulating intravenous/access ports; 15% from improper disposal; and 13.5% during or after blood draw. Needle safety devices need to be specifically designed for the unique home health care setting and for a standardized rate of calculating needlestick injuries in this setting.

Devices for preventing percutaneous exposure injuries caused by needles in healthcare personnel

BACKGROUND

Percutaneous exposure injuries from devices used for blood collection or for injections expose healthcare workers to the risk of blood borne infections such as hepatitis B and C, and human immunodeficiency virus (HIV). Safety features such as shields or retractable needles can possibly contribute to the prevention of these injuries and it is important to evaluate their effectiveness.

OBJECTIVES

To determine the benefits and harms of safety medical devices aiming to prevent percutaneous exposure injuries caused by needles in healthcare personnel versus no intervention or alternative interventions.

SEARCH METHODS

We searched CENTRAL, MEDLINE, EMBASE, NHSEED, Science Citation Index Expanded, CINAHL, Nioshtic, CISdoc and PsycINFO (until 11 November 2016).

SELECTION CRITERIA

We included randomised controlled trials (RCT), controlled before and after studies (CBA) and interrupted time-series (ITS) designs of the effect of safety engineered medical devices on percutaneous exposure injuries in healthcare staff.

DATA COLLECTION AND ANALYSIS

Two of the authors independently assessed study eligibility and risk of bias and extracted data. We synthesized study results with a fixed-effect or random-effects model meta-analysis where appropriate.

MAIN RESULTS

We included six RCTs with 1838 participants, two cluster-RCTs with 795 participants and 73,454 patient days, five CBAs with approximately 22,000 participants and eleven ITS with an average of 13.8 data points. These studies evaluated safe modifications of blood collection systems, intravenous (IV) systems, injection systems, multiple devices, sharps containers and legislation on the implementation of safe devices. We estimated the needlestick injury (NSI) rate in the control groups to be about one to five NSIs per 1000 person-years. There were only two studies from low- or middle-income countries. The risk of bias was high in 20 of 24 studies. Safe blood collection systems:We found one RCT that found a safety engineered blood gas syringe having no considerable effect on NSIs (Relative Risk (RR) 0.2, 95% Confidence Interval (95% CI) 0.01 to 4.14, 550 patients, very low quality evidence). In one ITS study, safe blood collection systems decreased NSIs immediately after the introduction (effect size (ES) -6.9, 95% CI -9.5 to -4.2) but there was no further decrease over time (ES -1.2, 95% CI -2.5 to 0.1, very low quality evidence). Another ITS study evaluated an outdated recapping shield, which we did not consider further. Safe Intravenous systemsThere was very low quality evidence in two ITS studies that NSIs were reduced with the introduction of safe IV devices, whereas one RCT and one CBA study provided very low quality evidence of no effect. However, there was moderate quality evidence produced by four other RCT studies that these devices increased the number of blood splashes when the safety system had to be engaged actively (relative risk (RR) 1.6, 95% CI 1.08 to 2.36). In contrast there was low quality evidence produced by two RCTs of passive systems that showed no effect on blood splashes. Yet another RCT produced low quality evidence that a different safe active IV system also decreased the incidence of blood leakages. Safe injection devicesThere was very low quality evidence provided by one RCT and one CBA study showing that introduction of safe injection devices did not considerably change the NSI rate. One ITS study produced low quality evidence showing that the introduction of safe passive injection systems had no effect on NSI rate when compared to safe active injection systems. Multiple safe devicesThere was very low quality evidence from one CBA study and two ITS studies. According to the CBA study, the introduction of multiple safe devices resulted in a decrease in NSI,whereas the two ITS studies found no change. Safety containersOne CBA study produced very low quality evidence showing that the introduction of safety containers decreased NSI. However, two ITS studies evaluating the same intervention found inconsistent results. LegislationThere was low to moderate quality evidence in two ITS studies that introduction of legislation on the use of safety-engineered devices reduced the rate of NSIs among healthcare workers. There was also low quality evidence which showed a decrease in the trend over time for NSI rates.Twenty out of 24 studies had a high risk of bias and the lack of evidence of a beneficial effect could be due to both confounding and bias. This does not mean that these devices are not effective.

AUTHORS' CONCLUSIONS

For safe blood collection systems, we found very low quality evidence of inconsistent effects on NSIs. For safe passive intravenous systems, we found very low quality evidence of a decrease in NSI and a reduction in the incidence of blood leakage events but moderate quality evidence that active systems may increase exposure to blood. For safe injection needles, the introduction of multiple safety devices or the introduction of sharps containers the evidence was inconsistent or there was no clear evidence of a benefit. There was low to moderate quality evidence that introduction of legislation probably reduces NSI rates.More high-quality cluster-randomised controlled studies that include cost-effectiveness measures are needed, especially in countries where both NSIs and blood-borne infections are highly prevalent.

Occupational exposure to bodily fluids in oral and maxillofacial surgery: an evaluation of reporting practices and attitudes among staff at a major teaching hospital in the UK

Our aim was to evaluate experience, practice, and beliefs about reporting of occupational exposures to blood and other body fluids among a sample of 88 healthcare providers working in oral and maxillofacial surgery at Sheffield Teaching Hospitals. We used a cross-sectional survey to evaluate awareness of the Trust's policy for reporting occupational exposure, recent incidence of exposure, and current reporting practices. Beliefs were measured using questions derived from the theory of planned behaviour. Fifty-five people responded, 14 of whom had been exposed to bodily fluids in the previous 12 months. Of those, 10 did not report it. Fifty-three respondents were certain that the Trust had a protocol in place for reporting sharps injuries to staff. Most (n=51) said the Trust had a protocol for reporting mucocutaneous exposure to blood. Respondents placed equal importance on reporting exposures that affected both themselves and patients, but intention to report exposure of patients was significantly higher than for themselves (z score -3.18, p<0.0001). We conclude that OMFS healthcare workers generally think that occupational exposures should be reported, but there are shortcomings in practice.

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.

Nurses and Occupational Exposures to Bloodborne Viruses in Poland

Study Objective.

To record descriptions of occupational exposures to blood, determine factors predictive of exposure, and identify interventions that might reduce the frequency of exposure.

Design.

An analytic, cross-sectional survey.

Study Population.

A total of 601 nurses from surgical wards, operating rooms, and emergency departments.

Study Instrument.

An anonymous questionnaire developed by the authors on the basis of previously published guidelines was distributed between January and March 2003.

Sampling.

Random, with 18 hospitals selected from 2 urban and rural locations.

Results.

Almost half of respondents reported having had at least 1 puncture injury during the preceding year, 1 in 5 had exposure via mucous membranes, and more than half had worked at least once with a recent abrasion or cut on their hands. The number of injuries was independent of age (P = .26), duration of practice (P = .21), and workplace setting (P = .78). The percentage of nurses without percutaneous exposure during the preceding year was significantly higher in the group that received special HIV/AIDS training than in the group that did not (95% confidence interval, 5.8-24.1%; P<.002). The most recent exposure was primarily caused by hollow-bore needles, involved the palm and fingers II-V, was self-inflicted, took place during an elective procedure, and was not reported to the hospital's infection control center by 74% of respondents. The most common reason for not reporting the exposure (38% of cases) was the conviction that the source patient was not infected.

Conclusions.

Because of the large number of occupational exposures to blood, especially those due to injuries with hollow-bore needles, nurses should adopt more adequate behavioral strategies to prevent the transmission of blood-borne pathogens. Policies for providing adequate education programs tailored to encourage nurses to report all exposures are urgently required.

Devices for preventing percutaneous exposure injuries caused by needles in healthcare personnel

BACKGROUND

Needlestick injuries from devices used for blood collection or for injections expose healthcare workers to the risk of blood borne infections such as hepatitis B and C, and human immunodeficiency virus (HIV). Safety features such as shields or retractable needles can possibly contribute to the prevention of these injuries and it is important to evaluate their effectiveness.

OBJECTIVES

To determine the benefits and harms of safety medical devices aiming to prevent percutaneous exposure injuries caused by needles in healthcare personnel versus no intervention or alternative interventions.

SEARCH METHODS

We searched CENTRAL, MEDLINE, EMBASE, NHSEED, Science Citation Index Expanded, CINAHL, Nioshtic, CISdoc and PsycINFO (until January 2014) and LILACS (until January 2012).

SELECTION CRITERIA

We included randomised controlled trials (RCT), controlled before and after studies (CBA) and interrupted time-series (ITS) designs on the effect of safety engineered medical devices on needlestick injuries in healthcare staff.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed study eligibility and risk of bias and extracted data. We synthesized study results with a fixed-effect or random-effects model meta-analysis where appropriate.

MAIN RESULTS

We included four RCTs with 1136 participants, two cluster-RCTs with 795 participants and 73,454 patient days, four CBAs with approximately 22,000 participants and seven ITS with an average of seven data points. These studies evaluated safe modifications of blood collection systems, intravenous (IV) systems, injection systems, multiple devices and sharps containers. The needlestick injury (NSI) rate in the control groups was estimated at about one to five NSIs per 1000 person-years. There was only one study from a low- or middle-income country. The risk of bias was high in most studies.In one ITS study that evaluated safe blood collection systems, NSIs decreased immediately after the introduction (effect size (ES) -6.9, 95% confidence interval (CI) -9.5 to -4.2) and there was no clear evidence of an additional benefit over time (ES -1.2, 95% CI -2.5 to 0.1). Another ITS study used an outdated recapping shield.There was very low quality evidence that NSIs were reduced with the introduction of safe IV devices in two out of four studies but the other two studies showed no clear evidence of a trend towards a reduction. However, there was moderate quality evidence in four other studies that these devices increased the number of blood splashes where the safety system had to be engaged actively (relative risk (RR) 1.6, 95% CI 1.08 to 2.36).There was no clear evidence that the introduction of safe injection devices changed the NSI rate in two studies.The introduction of multiple safety devices showed a decrease in NSI in one study but not in another. The introduction of safety containers showed a decrease in NSI in one study but inconsistent results in two other studies.There was no evidence in the included studies about which type of device was better, for example shielding or retraction of the needle.

AUTHORS' CONCLUSIONS

For safe blood collection systems, we found very low quality evidence in one study that these decrease needlestick injuries (NSIs). For intravenous systems, we found very low quality evidence that they result in a decrease of NSI compared with usual devices but moderate quality evidence that they increase contamination with blood. For other safe injection needles, the introduction of multiple safety devices or the introduction of sharps containers the evidence was inconsistent or there was no clear evidence of a benefit. All studies had a considerable risk of bias and the lack of evidence of a beneficial effect could be due both to confounding and bias. This does not mean that these devices are not effective.Cluster-randomised controlled studies are needed to compare the various types of safety engineered devices for their effectiveness and cost-effectiveness, especially in low- and middle-income countries.

Occupational bloodborne exposure incident survey & management of exposure incidents in a dental teaching environment

OBJECTIVES

The purpose of this study was to investigate the prevalence of occupational exposure incidents among undergraduate dental students and the factors associated with it in the educational dental clinics at Pharos University in Alexandria - Egypt, and to measure the commitment with applying infection control policy in the form of compliance with post-exposure management protocol and reporting exposure incidents.

MATERIALS AND METHODS

An anonymous self-administered questionnaire consisting of thirteen multiple-choice questions was distributed among 350 undergraduate dental students in mid-senior and senior levels during lectures at the end of the second semester of 2011, with a response rate of 90.00%.

RESULTS

About 62.00% of the senior students reported that exposures occurred outside the patient's mouth. A high percentage of both the mid-senior and senior students (74.70% and 70.70%, respectively) reported that they were exposed to multiple sources of incidents. The vast majority of studied groups stated that they didn't follow Infection Control Protocol after Incident Exposure.

CONCLUSION

The findings of this study confirm that dental students experience exposure incidents but are not likely to report them, thus it is important that the principles of infection control training and reporting of all exposure incidents continue to be emphasized throughout undergraduate dental education.

Is rapid hepatitis C virus testing from corpses a screening option for index persons who have died after mass-casualty incidents in high-prevalence settings in the field?

INTRODUCTION

We tested a commercially available rapid hepatitis C virus (HCV) test assay for its potential use for analyses of corpses as a screening option for index persons who have died after mass-casualty incidents in high-prevalence settings in the field.

MATERIALS AND METHODS

50 blood samples were drawn from 16 recently deceased confirmed HCV-positive patients whose corpses were stored at 4°C in the mortuary and were analysed at admission and up to 48 h post mortem by rapid serological testing using the ImmunoFlow HCV test (Core Diagnostics, Birmingham, UK) in comparison with automated serological assays and PCR. Samples from 50 HCV-negative corpses were also analysed.

RESULTS

The blood of only four of the 16 HCV-positive corpses reacted clearly with the ImmunoFlow HCV test, while in five cases the result was only weakly reactive and three cases showed very weak reactivity. Four of the infected corpses showed initially negative results, three of which became very weakly reactive 48 h post mortem. 49 out of 50 samples (98%) from HCV-negative corpses tested negative.

DISCUSSION

The rapid test system we investigated showed insufficient sensitivity regarding the identification of HCV positivity. Automated serological testing or PCR should be preferred if it is realistically available in the deployed military setting.

The comparison of sharps injuries reported by doctors versus nurses from surgical wards in the context of the prevalence of HBV, HCV and HIV infections

The aim of the study was to evaluate the nature and frequency of sharps injuries among doctors and nurses from the same surgical/gynecological wards and the prevalence of HBV/HCV/HIV infection.

MATERIAL AND METHODS

An anonymous cross-sectional sero-survey, with ELISA system used to detect anti-HBc, anti-HCV, anti-HIV, was conducted among 89 doctors and 414 nurses from 16 randomly selected hospitals in West Pomerania, Poland, between January-June 2009.

RESULTS

During the preceding 12 months, 82% doctors and 44.4% nurses (p<0.0001) had sustained at least one sharps injury; 12.3% doctors vs 2.2% nurses (p<0.003) sustained more than 10 injuries. The multivariable regression model revealed that being a doctor was associated with a greater odds (OR 4.2) of being injured with sharps. Sixty nine percent of nurses sustained a hollow-bore needle injury vs 8.9% doctors; p<0.001. Anti-HBc were found in 16.4% of doctors and 11.2% of nurses, p>0.28; anti-HCV - in 1.1% of doctors vs 1.4% of nurses, p>0.79; no anti-HIV positive cases were found. The analysis of potential risk factors for contracting a HBV revealed that for both job categories only length of employment was associated with an increased odds of being infected.

CONCLUSIONS

Although the prevalence of HBV/HCV infection between doctors and nurses does not differ significantly, modifiable risk factors for contracting a BBI such as frequency and nature of sharps injuries may differ, which call for tailoring preventive measures to specific job categories. Long lasting exposure to injury events should be taken into consideration while assessing the risk for accuiring an occupational infection with HBV, HCV or HIV.

Factors associated with needlestick and sharp injuries among hospital nurses: a cross-sectional questionnaire survey

BACKGROUND

The current status of needlestick or sharp injuries of hospital nurses and factors associated with the injuries have not been systematically examined with representative registered nurse samples in South Korea.

OBJECTIVE

To examine the incidence to needlestick or sharp injuries and identify the factors associated with such injuries among hospital nurses in South Korea.

DESIGN, SETTINGS AND PARTICIPANTS

A cross-sectional survey of hospital nurses in South Korea. Data were collected from 3079 registered nurses in 60 acute hospitals in South Korea by a stratified random sampling method based on the region and number of beds.

METHODS

The dependent variable was the occurrence of needlestick or sharp injuries in the last year, and the independent variables were protective equipment, nurse characteristics, and hospital characteristics. This study employed logistic regression analysis with generalized estimating equation clustering by hospital to identify the factors associated with needlestick or sharp injuries.

RESULTS

The majority (70.4%) of the hospital nurses had experienced needlestick or sharp injuries in the previous year. The non-use of safety containers for disposal of sharps and needles, less working experience as a registered nurse, poor work environments in regards to staffing and resource adequacy, and high emotional exhaustion significantly increased risk for needlestick or sharp injuries. Working in perioperative units also significantly increased the risk for such injuries but working in intensive care units, psychiatry, and obstetrics wards showed a significantly lower risk than medical-surgical wards.

CONCLUSIONS

The occurrence of needlestick or sharp injuries of registered nurses was associated with organizational characteristics as well as protective equipment and nurse characteristics. Hospitals can prevent or reduce such injuries by establishing better work environments in terms of staffing and resource adequacy, minimizing emotional exhaustion, and retaining more experienced nurses. All hospitals should make safety-engineered equipment available to registered nurses. Hospitals as well as specific units showing higher risk for needlestick and sharp injuries should implement organizational strategies to prevent such injuries. It is also necessary to establish a monitoring system of needlestick and sharp injuries at a hospital level and a reporting system at the national level in South Korea.

A comparison of syringe disposal practices among injection drug users in a city with versus a city without needle and syringe programs

BACKGROUND

The United States (U.S.) approved use of federal funds for needle and syringe programs (NSPs) in December 2009. This study compares syringe disposal practices in a U.S. city with NSPs to a U.S. city without NSPs by examining the prevalence of improperly discarded syringes in public places and the self-reported syringe disposal practices of injection drug users (IDUs) in the two cities.

METHODS

We conducted visual inspection walkthroughs in a random sample of the top-quartile of drug-affected neighborhoods in San Francisco, California (a city with NSPs) and Miami, Florida (a city without NSPs). We also conducted quantitative interviews with adult IDUs in San Francisco (N=602) and Miami (N=448).

RESULTS

In the visual inspections, we found 44 syringes/1000 census blocks in San Francisco, and 371 syringes/1000 census blocks in Miami. Survey results showed that in San Francisco 13% of syringes IDUs reported using in the 30 days preceding the study interviews were disposed of improperly versus 95% of syringes by IDUs in Miami. In multivariable logistic regression analysis, IDUs in Miami had over 34 times the adjusted odds of public syringe disposal relative to IDUs in San Francisco (adjusted odds ratio=34.2, 95% CI=21.92, 53.47).

CONCLUSIONS

We found eight-fold more improperly disposed syringes on walkthroughs in the city without NSPs compared to the city with NSPs, which was corroborated by survey data. NSPs may help IDUs dispose of their syringes safely in cities with large numbers of IDUs.

Work-related injury in the nursing profession: an investigation of modifiable factors

AIM

This paper is a report of a correlational study of the relationships between work-related injury-risk events and modifiable risk factors in a nursing population after controlling for socioeconomic factors.

BACKGROUND

Nurses are at high risk for work-related injury. Work-related injury is strongly influenced by psychosocial factors and physical job-related exposures, but the magnitude of effect from modifiable factors remains unclear.

METHOD

Data were based on the Work Outcomes Research Cost-benefit survey conducted in Australia during 2005 and 2006. The study sample of 5724 represented ~14% of nurses in Queensland, Australia. Logistic regression was used to determine the magnitude of association of psychological distress (represented by the Kessler 6 score: six-item scale of psychological distress), the number of health conditions and various socioeconomic factors with work place injury.

RESULTS

High psychological distress was associated with a 5% probability of injury. As the number of health conditions increased, the probability of injury increased; 3 and ≥ 6 health conditions increased the chance of injury by 5% and 15% compared with no health conditions. Compared with the total sample, nurses who reported high levels of psychological distress demonstrated greater sensitivity to the number of health conditions. Computation of the marginal effects showed little difference in the likelihood of injury when the total sample was compared with nurses with < 5 years of work experience.

CONCLUSION

Effective occupational health and safety workplace programmes that target modifiable factors such as psychological distress and physical health conditions may improve the health capital of nurses and productivity levels within the profession.

Increased risk of transmission of hepatitis C in open heart surgery compared with vascular and pulmonary surgery

BACKGROUND

We report a case of patient-to-surgeon transmission of hepatitis C virus (HCV), and the subsequent transmission of HCV to surgical patients.

METHODS

In 2007, a cardiac surgeon tested positive for hepatitis C. A complete look-back investigation was initiated that involved screening of all patients on the surgeon's operating lists between September 2004 and April 2007. Genotyping and phylogenetic analyses were performed where HCV RNA was detected.

RESULTS

Of the 499 patients invited to HCV testing, 431 responded, 13 of whom were found anti-HCV positive. One patient, who had surgery in August 2005, was found most likely to be the source of transmission to the surgeon. Of the 270 patients who had surgery after this incident, 10 became infected, giving an estimated rate of transmission of 3.7%. The HCV polymerase chain reaction positive samples were found to be the same genotype 1a strain by phylogenetic analyses. All the 10 subsequently infected patients had undergone open heart surgery, whereas none of the 103 noncardiac patients became infected, giving an estimated risk of transmission during open heart surgery of 6.0% (95% confidence interval [3.3% to 10.7%]).

CONCLUSIONS

The transmission rate from an HCV positive surgeon to patients in a cardiothoracic setting was higher than previously reported and significantly higher during open heart surgery compared with vascular and pulmonary surgery. These results indicate the need for unequivocal routines for testing and handling of HCV positive health care workers and patients.

Frequency and barriers of underreported needlestick injuries amongst Iranian nurses, a questionnaire survey

AIMS AND OBJECTIVES

To determine the frequency of needlestick injuries and barriers of reporting such injuries amongst Iranian nurses.

BACKGROUND

Exposure to blood-borne pathogens because of needlestick injuries in particular is a potential risk for healthcare workers, including clinical nurses. The burden of sharp injuries sustained by healthcare workers is still unclear, primarily because of underreporting.

DESIGN

A cross-sectional study was undertaken amongst 111 clinical nurses working in five major teaching hospitals in Tehran/Iran during 2007-2008 who were randomly selected.

METHODS

A validated self-reported questionnaire containing demographic characteristics and history of experiences with contaminated needlesticks as well as probably reason/s for underreporting such injuries was used.

RESULTS

More than half of the enrolled nurses (54.1%, n = 60) had no experience of contaminated injuries, while the rest of 45.9% (n = 51) had experienced at least one contaminated needlestick injuries during their clinical performance. More than one-third (34.0%, n = 38) had experienced a mean of 58 contaminated needlestick injuries during the past 12 months (crude incidence: 0.52 NSI/nurse/year). Only 14 nurses (36.8%) with needlestick injuries experiences had officially reported their experiences. The major reasons for not reporting needlestick injuries were dissatisfaction with follow-up investigations by officials after reporting the events (33.3%) and safe/low risk considering of source patients (29.2%).

CONCLUSIONS

Increased frequency and underreporting of needlestick injuries amongst Iranian nurses is going to be a major concern. As a preventive strategy, further interventions such as constant staff training, life-long learning and standardising postexposure procedures are recommended.

RELEVANCE TO CLINICAL PRACTICE

Determining the prevalence, burden and reasons for underreporting needlestick injuries by clinical nurses are required for establishing a preventive strategy to decrease hospital infections.

Syringe disposal among injection drug users in San Francisco

To assess the prevalence of improperly discarded syringes and to examine syringe disposal practices of injection drug users (IDUs) in San Francisco, we visually inspected 1000 random city blocks and conducted a survey of 602 IDUs. We found 20 syringes on the streets we inspected. IDUs reported disposing of 13% of syringes improperly. In multivariate analysis, obtaining syringes from syringe exchange programs was found to be protective against improper disposal, and injecting in public places was predictive of improper disposal. Few syringes posed a public health threat.

Evaluation of institutional practices for prevention of phlebotomy-associated percutaneous injuries in hospital settings

BACKGROUND

To reduce the incidence of phlebotomy-related percutaneous injuries (PIs), factors that contribute to these injuries must be identified. This study examined institutional phlebotomy practices, policies, perceptions, and culture to identify facilitators and barriers that appear to have the greatest impact in preventing injuries.

METHODS

During site visits at study hospitals, observational data were collected during the performance of phlebotomy. In addition, interviews and focus groups were conducted with hospital personnel involved in phlebotomy procedures.

RESULTS

Nine hospitals participated in the study. A total of 126 phlebotomy procedures were observed. Health care personnel chose devices with safety features for the majority of observed procedures (n = 122, 97%). Recommended phlebotomy practices for handling needles after use were observed in 42% to 92% of procedures. Adherence varied by type of device, occupation, and facility PI rate. In the 23 interviews and 9 focus groups, participants identified factors that facilitated PI prevention such as the availability and use of devices with safety mechanisms, adherence to recommended safe needle-handling practices, and institutional phlebotomy training.

CONCLUSION

The quantitative and qualitative data indicate that a wide array of factors can affect phlebotomy-related practices and perceptions. Prevention of PIs may require comprehensive, multifaceted intervention efforts to improve the safety culture and reduce PIs and exposure to bloodborne pathogens in health care facilities.

Review of personal protection equipment used in practice

Standard precautions offer a consistent approach to infection control that does not rely on knowledge or suspicion of infection, and contributes to staff and patient safety by reducing the risk of exposure to potentially infectious material. One of the cornerstones of standard precautions is the appropriate use of personal protective equipment (PPE) whenever contact with blood or body fluids is anticipated. However, evidence suggests that compliance with standard precautions including correct use of PPE is inadequate. Demographic and epidemiological changes in the U.K., and the drive to provide more complex patient care outside acute hospitals may lead to increased infection risks for both patients and community healthcare workers. This review examines the importance and use of PPE by community nurses and discusses the implications for practice of poor compliance with standard precautions. Recommendations for practice will be made aimed at improving compliance with this important element of standard precautions.

Prevalence and prevention of needlestick injuries among health care workers in a German university hospital

OBJECTIVE

Health care workers (HCWs) are exposed to bloodborne pathogens, especially hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV) through job-related risk factors like needlestick, stab, scratch, cut, or other bloody injuries. Needlestick injuries can be prevented by safer devices.

METHODS

The purpose of this study was to investigate the frequency and causes of needlestick injuries in a German university hospital. Data were obtained by an anonymous, self-reporting questionnaire. We calculated the share of reported needlestick injuries, which could have been prevented by using safety devices.

RESULTS

31.4% (n = 226) of participant HCWs had sustained at least one needlestick injury in the last 12 months. A wide variation in the number of reported needlestick injuries was evident across disciplines, ranging from 46.9% (n = 91/194) among medical staff in surgery and 18.7% (n = 53/283) among HCWs in pediatrics. Of all occupational groups, physicians have the highest risk to experience needlestick injuries (55.1%-n = 129/234). Evaluating the kind of activity under which the needlestick injury occurred, on average 34% (n = 191/561) of all needlestick injuries could have been avoided by the use of safety devices. Taking all medical disciplines and procedures into consideration, safety devices are available for 35.1% (n = 197/561) of needlestick injuries sustained. However, there was a significant difference across various medical disciplines in the share of needlestick injuries which might have been avoidable: Pediatrics (83.7%), gynecology (83.7%), anesthesia (59.3%), dermatology (33.3%), and surgery (11.9%). In our study, only 13.2% (n = 74/561) of needlestick injuries could have been prevented by organizational measures.

CONCLUSION

There is a high rate of needlestick injuries in the daily routine of a hospital. The rate of such injuries depends on the medical discipline. Implementation of safety devices will lead to an improvement in medical staff's health and safety.

Outpatient drug safety: new steps in an old direction

Iatrogenic injury from adverse drug events (ADEs) is a common and often preventable problem in modern medical practice. Attention to this problem has focused on the inpatient hospital setting and healthcare professionals. However, most medication is prescribed and used outside of hospitals and is managed by patients or lay caregivers in homes or workplaces. To address the public health problem of outpatient drug safety, interventions to prevent adverse events must recognize the central role of the patient in medication management and environmental factors specific to the outpatient setting. Lessons and techniques from the field of injury prevention should guide the development and implementation of safety interventions. First, Haddon's phase-factor matrix can be used to help conceptualize outpatient drug safety interventions. Second, interventions to improve outpatient drug safety should be patient-centered and extend beyond patient education to include engineering innovations and enforcement strategies. Third, the sustainability of active versus passive interventions should be considered when choosing safety interventions.

Potential work-related bloodborne pathogen exposures by industry and occupation in the United States part I: an emergency department-based surveillance study

BACKGROUND

Since the early 1990s, researchers have attempted to assess the magnitude of potential work-related bloodborne pathogen (BBP) exposures in the U.S. The only data-derived estimate of 385,000 needlestick and other sharps injuries per year was reported in 2004. The estimate was derived from a convenience sample and did not include exposures outside of hospitals. This study seeks to understand the magnitude and distribution of the exposures across all industries and occupations.

METHODS

Data were from the 1998 to 2000 National Electronic Injury Surveillance System (NEISS), a stratified probability-based sample of U.S. hospital emergency departments (EDs). NEISS covers all industries and occupations. National estimates of exposures and exposure rates (the number of exposures/1,000 full-time equivalents (FTE)) were computed.

RESULTS

An estimated 78,100 potential work-related exposures to BBP were treated in hospital EDs annually in the U.S. While hospitals accounted for 75% of all these exposures, 11 other industries had a substantial number of exposures. While registered nurses accounted for 36% of all exposures, 13 other occupations had a substantial number of exposures. Hospitals had the highest exposure rate of 11.3/1,000 FTE, followed by nursing homes (2.8), and residential care facilities without nursing (1.9). Registered nurses had the highest exposure rate of 15.3/1,000 FTE, followed by clinical laboratory technologists and technicians (13.9), and physicians (7.1).

CONCLUSIONS

While this study begins to more completely describe the problem of potential BBP exposure in the workplace, it is but a first step in further understanding the complex issues surrounding workplace BBP exposures.

Epidemiology of needlestick and sharps injuries among professional Korean nurses

Although needlestick and sharps injuries (NSI) are known to affect professional nurses at high rates, most studies depend on officially reported data and few have been undertaken in Korea. Thus, we surveyed a large cross-section of nurses from a hospital in Gangneung (response rate, 97.9%). Four hundred thirty-two incidents of NSI were reported by 263 nurses (79.7%) in the previous 12-month period (average, 1.31 events/nurse/year). Syringe needles were the most common devices, affecting 67.3% and comprising 52% of all NSI events. Sixty percent of all NSI events involved contaminated devices. Opening an ampoule or vial was the most common cause (affecting 35.2% of all nurses and accounting for 15.9% of all NSI events). Logistic regression indicated that nurses working in "other" departments were 5.4 times more likely to suffer any NSI (odds ratio [OR] = 5.4; 95% confidence interval [95% CI] = 2.0-15.2; P < .05) and 4.7 times more likely to incur a syringe-needle injury than nurses in intensive care units or inpatient departments (OR = 4.7; 95% CI = 2.0-11.6; P < .05). Younger-than-average nurses (< 27 years) were 4.5 times more likely to suffer NSI (OR = 4.5; 95% CI = 1.7-12.6; P < .05) and 3.1 times more likely to incur a syringe-needle injury (OR = 3.1; 95% CI = 1.4-7.0; P < .05). Working mixed shifts also increased the risk of any NSI (OR = 4.0; 95% CI = 1.7-10.4; P < .05) or syringe-needle NSI (OR = 4.4; 95% CI = 2.0-10.1; P < .05). Overall, our study suggests that NSI are common among Korean hospital nurses and represent a significant occupational burden for this large Asian demographic. Intervention and preventive strategies to help reduce their NSI exposures are urgently required in this country.

Mental health of healthcare workers who experience needlestick and sharps injuries

Healthcare workers (HCWs) are exposed daily to the risk of injury by needlesticks and other medical instruments. However, the psychiatric impacts of such injuries have not been evaluated. The aim of this study was to evaluate the mental health status of HCWs with experiences of needlestick and sharps injuries. A cross-sectional written survey was performed. The psychological symptoms before injury and current status were measured using the Beck Depression Inventory (BDI), Hamilton Anxiety Scale (HAM-A) and Perceived Stress Scale (PSS). The proportions of HCWs with and without needlestick and sharps injuries were 71.1% (n=263) and 28.9% (n=107), respectively. HAM-A and BDI scores were significantly higher among HCWs with injury experiences (p<0.01). HCWs with injury experiences exhibited higher PSS and BDI scores after the injury and higher levels of anxiety and depression. Particular attention should be directed towards the psychological consequences of needlestick and sharps injuries in HCWs.

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.

Prevalence of percutaneous exposure incidents amongst dentists in Queensland

BACKGROUND

Percutaneous exposure incidents (PEI) represent an important occupational health issue in dentistry, and one that can incur severe consequences from blood-borne infections. Given the importance of this topic, we considered it necessary to investigate the distribution and cause of PEI among Queensland dentists.

METHODS

In 2004, a self-reporting questionnaire was mailed to a random sample of 400 dentists on the register of the Queensland Branch of the Australian Dental Association.

RESULTS

A total of 285 questionnaires (73.1 per cent) were completed and returned. Of the respondents, 73.3 per cent were male and 26.7 per cent female, with a mean age of 45.2 years (SD = 11.9 years). Most were general dentists (89.1 per cent) with the remainder being specialists (10.9 per cent). More than three-quarters (78.5 per cent) reported damaging their gloves at least once during a clinical procedure in the previous 12-month period. Roughly one-quarter (27.7 per cent) had experienced at least one 'sharps' or needlestick injury in the previous 12 months, 16.1 per cent of which involved a contaminated instrument that had been previously used on a patient. The most common devices to cause 'sharps' injury in the previous 12 months were needles (14.4 per cent) and burs (10.2 per cent).

CONCLUSIONS

Although PEI clearly remains a major occupational health problem for Queensland dentists, the prevalence of needlestick injuries appears to be lower than other studies from developed countries. The identification of needlestick injuries as a common cause of PEI again stresses the importance of preventive strategies with respect to potential blood-borne infections. Further research is now needed to more carefully identify effective measures for reducing PEI among dental personnel.

Needlestick and sharps injuries among nurses in a tropical Australian hospital

Although needlestick and sharps injuries (NSI) represent a major hazard in nursing practice, most studies rely on officially reported data and none have yet been undertaken in tropical environments. Therefore, we conducted a cross-sectional NSI survey targeting all nurses within a tropical Australian hospital, regardless of whether they had experienced an NSI or not. Our overall response rate was 76.7%. A total of 39 nurses reported 43 NSI events in the previous 12 months. The most common causative device was a normal syringe needle, followed by insulin syringe needles, i.v. needles or kits and blood collection needles. Half of the nurses' NSI events occurred beside the patient's bed: drawing up medication was the most common reason. Nurses working in the maternity/neonatal wards were only 0.3 times as likely to have experienced an NSI as their counterparts in the medical or surgical wards. Overall, our study has shown that NSI events represent an important workplace issue for tropical Australian nurses. Their actual rate might also be higher than official reports suggest.

Needlestick and sharps injuries among nursing students

AIMS

This paper reports the first investigation of the prevalence and nature of needlestick injuries among Australian nursing students.

BACKGROUND

Needlestick and sharps injuries are the most efficient method of transmitting blood-borne pathogens between patients and healthcare staff. Although nurses are known to be a high-risk subgroup for these events, nursing students may be at even greater risk due to their limited clinical experience. Despite this fact, the epidemiology of needlestick and sharps injuries among nursing students has not been clearly elucidated in Australia.

METHODS

A questionnaire-based methodology adapted from other international investigations was conducted among nursing students. We recruited a complete cross-section of students from a large university nursing school in North Queensland, Australia, in March 2004, and analysed needlestick and sharps events as a percentage of all students and also as a proportion of all cases. Risk factors were evaluated using logistic regression.

RESULTS

From a group of 319 students, 274 successfully completed questionnaires were obtained (overall response rate 85.9%). A total of 38 students (13.9%) reported a needlestick or sharps injury during the previous 12 months. By causative item, 6.2% of students had been injured by a normal hollow-bore syringe needle, 3.6% by a glass item and 3.3% by an insulin syringe needle. Regarding prior usage, 81.6% of all injuring items were unused, 15.8% had been used on a patient and the status of 2.6% was unknown. Most needlestick injuries occurred either in the nursing laboratory (45%) or the teaching hospital (37%). Opening the needle cap was the most common causative event (28% of all cases). A total of 39.5% of needlestick injuries were not reported. The main reason for non-reporting was that the item was unused (42%). Logistic regression analysis revealed that students in the third year were 14.8 times more likely to have experienced a needlestick injury than their counterparts in other years (odds ratio 14.8, 95% confidence interval 5.2-50.3, P < 0.01). These injury rates were higher among Australian nursing students than in other international studies.

CONCLUSIONS

Although hepatitis B vaccination coverage among the students was excellent, it is important that the principles of infection-control training and reporting of all needlestick and sharps continue to be emphasized throughout undergraduate nursing education.

Occupational exposure to blood and risk of bloodborne virus infection among health care workers in rural north Indian health care settings

BACKGROUND

Approximately 3 million health care workers (HCWs) experience percutaneous exposure to bloodborne viruses (BBVs) each year. This results in an estimated 16,000 hepatitis C, 66,000 hepatitis B, and 200 to 5000 human immunodeficiency virus (HIV) infections annually. More than 90% of these infections are occurring in low-income countries, and most are preventable. Several studies report the risks of occupational BBV infection for HCWs in high-income countries where a range of preventive interventions have been implemented. In contrast, the situation for HCWs in low-income countries is not well documented, and their health and safety remains a neglected issue.

OBJECTIVE

To describe the extent of occupational exposure to blood and the risk of BBV infection among a group of HCWs in rural north India.

METHODS

A cross-sectional survey of HCWs from 7 rural health settings gathered data pertaining to occupational exposure to blood and a range of other relevant variables (eg, demographic information, compliance with Universal Precautions, perception of risk, knowledge of BBVs). A mass action model was used to estimate the risk of occupational BBV infection for these HCWs over a 10-year period.

RESULTS

A total of 266 HCWs returned questionnaires (response rate, 87%). Sixty-three percent reported at least 1 percutaneous injury (PI) in the last year (mean no. = 2.3) and 73% over their working lifetime (mean no. = 4.2). Predictors of PI during the last year were hospital site, job category, perception of risk, and compliance with Universal Precautions.

CONCLUSION

The high level of occupational exposure to blood found among this group of rural north Indian HCWs highlights the urgent need for interventions to enhance their occupational safety to prevent unnecessary nosocomial transmission of BBVs.

Needlestick and sharps injuries among nurses in the healthcare sector in a city of western Turkey

The aims of this study were to determine the rate of bloodborne infections after needlestick and sharps injuries in nurses at work, to estimate the number of vaccinations administered, and to assess whether universal precautions were being followed. The study involved 289 nurses working in five hospitals and six primary healthcare centres. Between 1 April 2002 and 31 June 2002, a total of 139 practising nurses were included in the study following a needlestick or sharps injury. The results of completed questionnaires were collated, and Chi-squared test was used for analysis. The rate of hollow-bored needle-related injuries was 76.2% (106/139). Most nurses (69.1%) did not report any details of their injuries and 32.4% (45/139) of nurses had not been vaccinated against hepatitis B virus (HBV). Only 5.3% of the nurses who responded to the compliance question indicated that they always complied with universal precautions. Of 139 nurses, 1.4% and 7.9% showed evidence of HBV infection and hepatitis C virus (HCV) infection, respectively. All those who had hepatitis B were aged 30 years or under, whereas most of those who were anti-HCV positive (81.8%) were over 30 years old (P < 0.05). Nurses working in the Turkish healthcare sector are frequently exposed to bloodborne infections. Precautions and protection from needlestick and sharps injuries are important in preventing infection of nurses. Education about the transmission of bloodborne infections, vaccination and post-exposure prophylaxis must be implemented. Further investigations are warranted to elucidate the risk to nurses of contracting these potentially serious infections.

Universal precautions: a survey of community nurses' experience and practice

BACKGROUND

Universal precautions are a set of guidelines which aim to protect health care workers from blood-borne infections. Community nurses often have to deliver care to people in less than ideal home conditions, their ability to comply with all universal precautions may therefore be compromised.

AIMS AND OBJECTIVES

This paper presents the findings of a questionnaire survey which aimed to explore community nurses' experience and practices of using universal precautions.

DESIGN AND METHODS

A questionnaire survey was used for this study. All community learning disability nurses, community mental health nurses and generic community nurses from one Welsh Health Authority were surveyed (n = 543) with a response rate of 70%.

RESULTS

The majority of community nurses reported compliance with universal precautions, although a small number of nurses stated that they re-sheathed needles, inappropriately stored sharps containers, inadequately wore gloves and experienced difficulties in handwashing.

CONCLUSIONS AND RELEVANCE TO CLINICAL PRACTICE

Community nurses work in a unique and unpredictable environment, which may result in nurses being unable to comply with existing universal precautions guidelines. The production of new infection control guidelines for the community by the National Institute of Clinical Excellence in June 2003, has addressed some of the difficulties faced by community nurses.

Jet Injection of Local Anesthetic Decreases Pain of Arterial Cannulation in Awake Neurosurgical Patients

Arterial cannulation through the standard skin wheal of local anesthetic raised with a needle may be painful. The authors compared the efficacy of local anesthetic injected via a 25G needle versus a Bioject jet injector for arterial cannulation in awake neurosurgical patients. After institutional review board approval, 40 patients were randomized to receive 0.3 mL 1% lidocaine adjusted to pH 7.0 with NaHCO3 by Bioject with a 2-cm spacer between the syringe and skin or by 25G needle injection. Two pain assessments were used at the time of local anesthetic injection and at arterial cannulation. Patients rated their pain on a visual analog scale (VAS) (0 = no pain, 100 = worst pain). Observers scored patient response as 0 (no response), 1 (flinch), or 2 (withdrawal). The VAS at injection was 23 +/- 19 for the needle group and 3 +/- 6 for the Bioject group (P < 0.001). The VAS at arterial cannulation was 39 +/- 25 for the needle group and 15 +/- 22 for the Bioject group (P < 0.001). Median observer scores at injection and cannulation were 1 (range 0-2) for the needle group and 0 (range 0-2) for the Bioject group (P < 0.001). Patients in the Bioject group experienced significantly less pain during lidocaine administration and at the time of arterial cannulation by their own and by an observer's assessment than the needle injection group. Jet injection of local anesthetic should be considered prior to arterial cannulation in awake patients.

Sharps injury reduction using Sharpsmart--a reusable sharps management system

Sharps containers are associated with 11-13% of total sharps injuries (SI) yet have received little attention as a means of SI reduction. A newly developed reusable sharps containment system (Sharpsmart) was trialed in eight hospitals in three countries. The system was associated with an 86.8% reduction of container-related SI (CRSI) (P=0.012), a 25.7% reduction in non-CRSI (P=0.003), and a 32.6% reduction in total SI (P=0.002) compared with historical data. The study concludes that the Sharpsmart system is an effective engineered control in reducing SI.

Subnotificação de acidentes com perfurocortantes na enfermagem

Os objetivos da pesquisa foram: identificar os acidentes de trabalho que ocasionaram injúrias percutâneas entre trabalhadores de enfermagem, identificar se os acidentes foram ou não notificados e conhecer os motivos da não notificação. Pesquisa descritiva com análise quantitativa dos dados coletados através de 394 entrevistas com trabalhadores de enfermagem de dois hospitais do Estado de São Paulo. Os resultados revelaram que os 394 trabalhadores, 30% da população, sofreram acidentes de trabalho durante o ano de 2001 e desses 277 (70,30%) foram causados por injúrias percutâneas, sendo 173 (62,45%) acidentes notificados e 104 (37,55%) não notificados. Os motivos que levaram a não notificação estavam relacionadas a crenças, falta de conhecimentos e informações sobre o risco de contaminação e forma de registro dos dados.

A review of sharps injuries and preventative strategies

Exposure to bloodborne pathogens from sharps injuries continues to pose a significant risk to healthcare workers (HCW). The number of sharps injuries sustained by HCW is still unclear, primarily due to under-reporting. In this review a mean rate of 4.0% (range 1.0-6.2%) sharps injuries per 10000 HCW was calculated from eight studies involving more than 7000 HCW. Nurses and doctors were most at risk of sharps injuries, frequently from hollow-bore needles. Approaches to reduce this risk have included education and training on the safe handling and disposal of sharp devices, awareness campaigns and legislative action. More recently, preventative strategies have focused on needle protective devices, which may reduce the rate of sharps injuries. Introducing needle protective devices should be considered particularly in high-risk areas, after training, education, evaluation and cost-benefit analysis.

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.
