Percutaneous exposure incidents of the health care personnel in a newly founded tertiary hospital: a prospective study

Occupational exposure to Blood and Body Fluids among Healthcare Professionals in a military hospital in Greece: A retrospective single-center study

BACKGROUND

Healthcare Professionel (HCP) worldwide are subjected to various occupational hazards, including exposure to Blood and Body Fluids (BBF). However, with systematic training and supervision, the impact of such incidents can be significantly mitigated.

OBJECTIVE

This study aims to assess the incidence of occupational exposure to BBF among HCPs reported to a military hospital over a five-year period. Additionally, it seeks to explore the characteristics of the affected HCP and the conditions of exposure, and to evaluate HCP' overall compliance with the hospital's guidelines.

METHODS

This is a retrospective, single-center study that includes all self-reported forms submitted from January 1, 2019, to December 31, 2023.

RESULTS

The overall incidence of BBF exposure was 3.05 per 100 full-time employment-years (FTEYs) or 3.01 per 100 HCP per year, whereas the incidence of needlesticks and sharps injuries (NSSIs) was 2.73 per 100 FTEYs or 2.54 per 100 HCPs per year. Overall HCP' compliance was 34.1%, with an increase from 1.6% in 2019 to 45.9% in 2023.

CONCLUSIONS

There is a need for a unified process for the collection of nationwide, longitudinal data on exposure to BBF, as well as for the development of targeted training programs on occupational health and safety for HCP.

Needle Stick Injury Among Healthcare Workers in a Tertiary Care Setting in Dehradun, Sub-Himalayan Region: A Four-Year Record-Based Study

INTRODUCTION

Needlestick injuries (NSIs) represent a significant occupational health risk in healthcare settings. These injuries, caused by contaminated sharps such as needles, vials, and scalpel blades, can lead to percutaneous exposure to infectious materials. Despite the severity of NSIs, they often go unreported, highlighting a critical gap in occupational safety protocols.

AIMS

This study aimed to investigate the occurrence of NSIs among healthcare workers (HCWs) by sex, profession, and working areas. It also sought to explore the underlying reasons for these injuries and the factors contributing to their underreporting.

METHODOLOGY

Adhering to the RECORD guidelines (Reporting of studies Conducted using Observational Routinely Collected Data), this record-based study involved a retrospective analysis of reported NSIs. Data were collected from voluntary reports by HCWs who experienced NSIs or exposure to potentially infectious materials such as blood and body fluids. Statistical analysis was conducted using IBM SPSS Statistics for Windows, Version 16 (Released 2007; IBM Corp., Armonk, New York) and Microsoft Excel 2010 (Microsoft Corporation, Redmond, Washington).

RESULTS

Data from 142 participants indicated a higher proportion of females experiencing NSIs compared to males, with rates of 57.7% pre-COVID and 60.6% during COVID. There were notable shifts in NSI rates across professions, with increases observed among staff nurses and ward attendants/helpers. Analysis of injury circumstances revealed a decrease in sampling procedure-related injuries but an increase during intravenous procedures and biomedical waste segregation. Injuries occurring on the right-hand index finger decreased from 52.1% pre-COVID to 31% during COVID, while those on the left-hand index finger increased from 19.7% pre-COVID to 39.4% during COVID. Statistically significant associations were found between the injury site and the place of occurrence (p=0.021). Healthcare professionals commonly cleansed the site with disinfectants and used personal protective equipment (PPE) kits, with increased PPE usage noted during the COVID-19 pandemic. These findings emphasize the evolving dynamics of NSIs among HCWs and underscore the importance of tailored preventive measures during pandemics.

Time to consider blunt needles for implant surgery? A systematic review and meta-analysis shows that blunt suture needles reduce glove perforation

BACKGROUND

Despite a recent Cochrane Review demonstrating blunt suture needles are safer for surgeons, the use of blunt suture needles has not become widely adopted. In the 'Implant Era', with the value of medical implant companies to surpass $145 billion by 2027, should we re-examine the use of blunt suture needles, especially to reduce infection in implant surgery? We performed a systematic review and meta-analysis of randomised controlled trials (RCTs) assessing whether blunt suture needles reduce risks to surgeons and patients.

METHODS

A systematic review and meta-analysis was performed per PRISMA guidelines. PubMed, Cochrane and EMBASE databases were searched for RCTs. Dichotomous variables were pooled as risk ratios (RR) and associated 95% confidence intervals (CI) using the MH method. Random or fixed effects modelling use was based on statistical heterogeneity (I2).

RESULTS

14 RCTs were identified with 2488 patients. The RCTs included laparotomies, caesarean sections, episiotomies, and orthopaedic surgeries. Blunt suture needles when compared with sharp needles resulted in a significant reduction in glove perforation; RR: 0.47, 95% CI [0.37 to 0.60] and needlestick injuries, RR: 0.50, 95% CI [0.26 to 0.97]. Sharp needles caused more wound infections, but the result was not statistically significant; RR: 2.73, 95% CI [0.54 to 13.76], p 0.22. Surgeon's satisfaction decreased with blunt needles compared with sharp (RR: 1.22, 95% CI [1.09 to 1.37]).

CONCLUSION

Blunt suture needles are safer than sharp needles for surgeons and likely reduce risks to patients. This, however, comes at the cost of decreased ease of use. The authors recommend the routine use of blunt suture needles, especially in implant surgery.

Underreporting of work accidents associated with blood-borne risk factors

BACKGROUND

Work accidents (WA) due to percutaneous or mucocutaneous injury are extremely frequent among health professionals. The notification of these accidents ensures not only the compliance with legal requirements, but it also enables health institutions to develop, implement and evaluate strategies to prevent them. This study aimed to estimate the proportion of underreporting of work accidents caused by percutaneous and mucocutaneous lesions in a hospital setting, as well as its determinants.

METHODS

A self-administered questionnaire was made available to all hospital employees. Age, gender, professional category and type of service adjusted odds ratios (OR) and 95% confidence intervals (95%CI) were computed by multivariate logistic regression models.

RESULTS

Underreporting of WA associated with biological risk factors was high, particularly in accidents by mucocutaneous injury (80.9%). Physicians were the professional category that least reported this type of work accidents (OR=4.64; 95%CI 2.20-9.78). The main determinants of underreporting were the underestimation of the risk of transmission and the excessive bureaucracy.

CONCLUSIONS

The underreporting of work accidents associated with biological risk factors was considerable and it contributes to a high degree of uncertainty on accidents' characterization.

What were the changes during the COVID-19 pandemic era concerning occupational risks among health care workers?

BACKGROUND

Accidental exposure to percutaneous needle stick and sharp injuries (NSSIs) and blood and other body fluids is the unintended contact with risky medical instruments or patient secretions during a medical intervention. During the COVID-19 pandemic, the significance of occupational injuries in healthcare professionals was revealed once again. To assess the occupational injuries, we compared rates, distribution and type of exposure to blood and body fluids and NSSIs of health care workers for 2019 (pre-pandemic era) and 2020 (pandemic era) years, respectively.

MATERIAL AND METHODS

Our study included data collected by the 'Hospital Infection Control Committee' for the years 2019-2020. Data collected using the active surveillance method were analyzed retrospectively.

RESULTS

During 2019 (pre-pandemic period) and 2020 (pandemic period), 112 (27.65%₀) and 82 (21.4%₀) NSSIs reported, respectively. Of the exposed HCWs in 2019 (pre-pandemic period), 16.8%₀ (14) were doctor, 53.6%₀ (60) were nurse and 47.4%₀ (14) were intern doctors. In the 2020 (pandemic period), NSSIs were observed most frequently in nurses and cleaning staff, 50.24%₀ and 33.64%₀, respectively. Concerning the total percentage of exposure to blood and other body fluids, a slight increase was revealed from 1.48%₀ to 2.62%₀ in 2019 and 2020, respectively. A significant decrease in exposure rate was reported among the doctors between the pre-pandemic and pandemic era; 3.6%₀ and 1.19%₀ at 2019 and 2020, respectively. A significant increase in exposure rate was reported among the nurses between pre-pandemic and pandemic era; 0.8%₀ and 6.89%₀, respectively.

CONCLUSION

In conclusion, the exposure to NSSIs during the pandemic period decreased; however, there was no severe difference at pre-pandemic and pandemic periods concerning exposure to blood and body fluids. Well-designed training and awareness programs can be effective in preventing exposure to NSSIs and blood and other body fluids and exposure to respiratory acquired viruses.

Time Trends of Percutaneous Injuries in Hospital Nurses: Evidence of the Interference between Effects of Adoption of Safety Devices and Organizational Factors

Few studies have focused on the combined effects of devices and work organization on needlestick injuries trends. The aim of the study was to estimate trends of percutaneous injury rates (IR) in nurses (N) and nurse assistants (NA) over a 10 year period, in which passive safety devices were progressively adopted. Percutaneous and mucocutaneous injuries registered in a University Hospital in Northern Italy in Ns and NAs in 2007–2016 were analyzed. Organizational data were also available on shift schedules, turnover, downsizing and age- and skill-mix. We estimated IRs per 100 full-time equivalent workers from Poisson models and their average annual percent changes (APC) from joinpoint regression model. In the entire period, monotonic decreases in percutaneous IRs occurred among day-shift Ns (APC = −20.9%; 95% CI: −29.8%, −12%) and NAs (APC = −15.4%; −32.9%, 2.2%). Joinpoint modeling revealed a turning point in 2012 for night-shift Ns, with a steady decline in 2007–2012 (APC = −19.4%; −27.9%, −10.9%), and an increase thereafter (APC = +13.5%; 1.5%, 25.5%). In comparison to 2008 and 2012, in 2016 night-shift Ns were 5.9 and 2.5 times more likely to be younger and less qualified or experienced than day-shift Ns. The observed declines in percutaneous injury rates occurred in a time period when safety devices were progressively implemented. The causal nature of multiple exposures and organizational procedures in affecting injury time trends should be further addressed by quasi-experimental studies.

Occupational Exposure to Blood and Body Fluids among Medical Laboratory Science Students of the University of Health and Allied Sciences during Vocational Internship in the Volta Region of Ghana

Medical laboratory science students (MLSS), likewise health care workers (HCW), invariably get exposed to blood and body fluids (BBF) of patients. The degree of exposure of these students is even worsened due to their inexperience, which is usually revealed during their vocational training programme. This study therefore determined the prevalence of exposure to BBF and its risk factors among MLSS at the University of Health and Allied Sciences (UHAS). A cross-sectional survey was employed using simple random sampling to enrol 178 students into the study. The study was conducted from February 1 to March 31, 2018, after the annual vocational training programme completed in August 2017. Self-administered questionnaires based on the objectives of the study were given out to participants to complete after their consent was sought. Descriptive data were reported as absolute number with percentages, whereas bivariate and multiple logistic regressions were done to describe relationship between risk factors and exposure to BBF. The study findings revealed that, out of 178 MLSS that participated, 90 (50.6%) experienced at least one exposure to BBF. Also, work experience before university education increased the chances of exposure to BBF (AOR = 7.37, 95% CI = 1.22–44.43, pvalue = 0.029) compared with those with no experience. In contrast, adequate personal protective equipment (PPE) reduced the tendencies of exposure to BBF (AOR = 0.41, 95% CI = 0.20–0.88, p value = 0.023) compared with students who had insufficient PPE. The study showed high, 50.6% (95% CI: 43.0%–58.1%), exposure to BBF. Work history and sufficient PPE were the most significantly associated risk factors. In view of this, there is the need to promote training and education on exposure to BBF particularly among experienced students and also encourage health facilities to continue providing enough PPE for students during their annual obligatory vocational internship programmes.

Do training and needle-safety devices prevent needlestick injuries? A systematised review of the literature

This systematised review was undertaken to appraise research on the effects of training and the use of needle-safety devices (NSDs) on the prevention of needlestick injuries (NSIs) among health workers, focusing on a European perspective. A literature search from 2007 to 2017 was performed, which identified six studies that investigated the introduction of training and NSDs and their affect on NSIs. The six chosen studies identified that training, as well as the adoption of NSDs, has an impact on preventing NSIs. However, further information is required on the content and mode of delivery of training and on which types of NSDs are most effective at preventing injuries. This will help healthcare workers to understand and implement the most effective strategies to prevent injuries. This article provides a critique of the research approaches used in the six studies.

Hepatitis B vaccination coverage among healthcare workers at national hospital in Tanzania: how much, who and why?

Background

Hepatitis B vaccination for healthcare workers (HCWs) is a key component of the WHO Hepatitis B Elimination Strategy 2016–2021. Data on current hepatitis B vaccine coverage among health care workers in Sub-Saharan Africa are scarce, but these data are vital for effective programming. We assessed the proportion of HCWs vaccinated for hepatitis B and the factors associated with adequate vaccination coverage at a national hospital in Tanzania.

Methods

A descriptive cross-sectional study was conducted among consenting healthcare workers between 30th July and 30th September 2015. Vaccination histories were obtained through self-administered questionnaires. Means and proportions were used to summarize the data. Student’s t and chi-squared tests were used as appropriate. Logistic regression was used to determine the factors associated with vaccination.

Results

A total of 348 HCWs were interviewed, of whom 198 (56.9%) had received at least one dose of hepatitis B vaccination, while only 117 (33.6%) were fully vaccinated. About half of the 81 HCWs with partial vaccination (49.4%) had missed their subsequent vaccination appointments. Among unvaccinated HCWs, 14 (9.3%) had either HBV infection or antibodies against HBV infection upon pre-vaccination screening. However, the remaining participants were not vaccinated and did not know their immune status against HBV.

Nearly all respondents (347, 99.3%) had heard about the hepatitis B viral vaccine. The following reasons for non-vaccination were given: 98 (65.3%) reported that they had not been offered the vaccine; 70 (46.7%) observed standard precautions to ensure infection prevention and 60 (41.3%) blamed a low level of awareness regarding the availability of the hepatitis B vaccine.

Conclusion

The current vaccination coverage among practicing healthcare workers at Muhimbili National Hospital is low, despite a high level of awareness and the acceptance of the vaccine. Expedited and concerted efforts to scale vaccine uptake should include improved access to the vaccine, especially for newly recruited HCWs. The extension of the study to private healthcare settings and lower-level facilities would be useful.

Period Prevalence and Reporting Rate of Needlestick Injuries to Nurses in Iran: A Systematic Review and Meta-Analysis

The purpose of this systematic review and meta-analysis was to provide a precise estimate of the period prevalence of needlestick injuries (NSI) among nurses working in hospitals in Iran and the reporting rate of NSI to nurse managers. We searched both international (PubMed, Scopus and the Institute for Scientific Information) and Iranian (Scientific Information Database, Iranmedex and Magiran) scientific databases to find studies published from 2000 to 2016 of NSI among Iranian nurses. The following keywords in Persian and English were used: "needle-stick" or "needle stick" or "needlestick," with and without "injury" or "injuries," "prevalence" or "frequency," "nurses" or "nursing staff," and "Iran." In a sample of 21 articles with 6,480 participants, we estimated that the overall 1-year period prevalence of NSI was 44% (95% confidence interval [CI], 35-53%) among Iranian nurses. The overall 1-year period prevalence of reporting NSI to nurse managers was 42% (95% CI, 33-52%). In meta-regression analysis, sample size, mean age, years of experience, and gender ratio were not associated with prevalence of NSI or reporting rate. The year of data collection was positively associated with period prevalence of NSI (p < .05), but not with the period prevalence of reporting NSI to nurse managers. Results indicated a high NSI period prevalence and low NSI reporting rate among nurses in Iran. Thus, effective interventions are required in hospitals in Iran to reduce the prevalence and increase the reporting rate of NSI. © 2017 Wiley Periodicals, Inc.

Bloodborne pathogen exposures: Difference in reporting rates and individual predictors among health care personnel

BACKGROUND

Employees in health care settings are at varying risk for bloodborne pathogen (BBP) exposures. We compared differences in reporting rates of BBP exposures among health care personnel during 2 different time periods, assessing job category, years of experience, and sex as potential predictors for exposure.

METHODS

A retrospective review of the employee health department BBP database at 2 time periods (September 1, 2012-April 30, 2013, and September 1, 2013-April 30, 2014) in which 2 different reporting protocols (call center vs pager) was used. A survey was administered to assess reported and unreported exposures within a 12-month period.

RESULTS

BBP exposures were highest among residents and lowest among students. Physicians' reporting rate doubled when the call center was no longer used (relative risk, 2.40; 95% confidence interval [CI], 1.04-5.52). Percutaneous injuries were the most common (78.3%), and most occurred in the operating room or postanesthesia unit (30.8%) and patient rooms (28.9%). Of 1,105 survey respondents, 103 (9.3%) recalled some type of exposure, but only 80 (77.7%) reported these exposures. When accounting for years of experience and sex, job category was significantly associated with injury or exposure within the previous 12 months (P < .001). Risk of exposure among residents was 3 times higher (odds ratio, 3.10; 95 CI, 1.60-6.00) than nurses.

CONCLUSIONS

Risk and reporting behaviors of BBP exposures vary widely across different providers. Training and education to prevent BBP exposures may need to be tailored toward different provider types.

Accidental blood exposures among emergency medicine residents and young physicians in France: a national survey

The aim of the present study was to investigate the epidemiological characteristics of blood or fluid exposure (BFE) and occupational infection risk among emergency medicine (EM) residents and young physicians (<35 years old) in France. We led a cross-sectional, anonymous, online survey. 1779 participants were contacted with a response rate of 36 % (n = 633). Among the respondents, 459 (72 %) reported at least one BFE. Among participants with at least one BFE, 35 % (n = 163) never reported the exposure to the relevant medical authorities or support. Among participants who reported exposure, 63 % (n = 232) did it immediately. Among participants who never or not systematically reported their BFE, most of them (62 %, n = 181/289) did not do so because the procedure was too long, and 28 % (n = 82/289) estimated the risk as low even if only one-third (n = 166/458) checked their HIV status even though the BFE was at a transmission risk. Circumstances in which the participants had the most BFE were: suturing 57 % (n = 262/457) and when making precipitated gestures 24 % (n = 111/457). The latest exposures were caused by a solid needle in 42 % (n = 191/455) or hollow-bore needle in 27 % (n = 123/455). Post-exposure reporting rates were low. Reporting procedure itself and self-management were the main reasons for BFE underreporting. Simplifying procedures might increase BFE reporting, and allow appropriate post-exposure counseling and/or prophylaxis.

The epidemiology of blood-contaminated needlestick injuries among veterinarians in Portugal

Needlestick injuries (NIs) are considered a substantial occupational health and safety hazard in contemporary health care practice. Unlike human medicine where much effort has been devoted to reduce the incidence of these events, the same aggressive approach has not been used in veterinary medicine. This study investigated the occurrence of blood-contaminated NIs in Portuguese veterinarians. Participants of a veterinary meeting were asked to complete a questionnaire-based survey. Univariate and multivariate logistic regression analyses were performed to produce predicted probabilities for NI episodes in veterinarians. From the total of 373 enrolled veterinarians, 293 (78.5%) reported having had at least one NI during their professional life. Veterinarians working with dogs were more likely to have experienced a NI (adjusted odds ratio [aOR]: 145.74, P < .001). The high level of NIs observed in these professionals shows that NIs are a potential occupational health problem in Portuguese veterinarians, with the possibility for transmission of haematogenous zoonosis.

Epidemiology of hepatitis C in Greece

Hepatitis C is a global health issue and constitutes a major cause of chronic liver disease worldwide. In this article, a comprehensive literature search was conducted for the prevalence of hepatitis C virus (HCV) infection in Greece, since data on the HCV prevalence, viremia and genotypes are important for developing strategies to manage or eliminate HCV infection. In addition, the pattern of HCV infection was analyzed according to the geographic region and the risk factors. These differences reflect not only distinct epidemiological characteristics among populations, but also differences on the strategy of data acquisition and quantification. Although there are not enough data, the estimation of the current prevalence of Hepatitis C in Greece ranges from 0.5% to 2%. The most important risk factors for HCV infection include blood product transfusion, intravenous drug use, chronic hemodialysis, organ transplantation, occupational exposure, sexual transmission, and vertical transmission. Because of lack of vaccine or effective post-exposure prophylaxis for HCV, the main focus of prevention is to recognize and control these risk factors. HCV infection in Greece is closely associated with the development of chronic liver disease, cirrhosis, and primary hepatocellular carcinoma. As far as the genotype distribution is concerned genotype 1 estimated to be 45%-47% and it constitutes the prevalent genotype in Greece, followed by genotype 3.

Reducing the underreporting of percutaneous exposure incidents: A single-center experience

Although risk reduction strategies have been implemented throughout the world, underreporting of percutaneous exposure incidents (PEIs) is common among exposed health care workers. The aim of this study was to determine the incidence rate of reported PEIs before and after implementation of an intensified reporting management policy. The introduction of an intensified reporting system led to significantly increased reporting after a PEI has occurred. However, continuous education needs to be provided to improve awareness.

Occupational exposure to blood and body fluids among health-care workers in Serbia

OBJECTIVES

The aim of this study was to examine the epidemiology of occupational accidents and self-reported attitude of health-care workers (HCWs) in Serbia.

SUBJECTS AND METHODS

A cross-sectional study was conducted among HCWs in selected departments of five tertiary care hospitals and in one secondary care hospital in February 2012. A previously developed self-administered questionnaire was provided to HCWs who had direct daily contact with patients. χ(2) test and Student's t test were used for statistical analysis of the data.

RESULTS

Of the 1,441 potential participants, 983 (68.2%) completed the questionnaire: 655 (66.7%) were nurses/medical technicians, 243 (24.7%) were physicians and 85 (8.6%) were other personnel. Of the 983 participants, 291 (29.6%) HCWs had had at least one accident during the previous year and 106 (40.2%) of them reported it to the responsible person. The highest prevalence (68.6%) of accidents was among nurses/technicians (p = 0.001). Accidents occurred more often in large clinical centers (81.1%; p < 0.001) and in the clinical ward, intensive care unit and operating theater (p = 0.003) than in other departments. Seventy-six (13.1%) nurses/medical technicians had an accident during needle recapping (p < 0.001). Of all the HCWs, 550 (55.9%) were fully vaccinated, including significantly more doctors (154, 63.4%) than participants from other job categories (p < 0.001).

CONCLUSION

There was a relatively high rate of accidents among HCWs in our hospitals, most commonly amongst nurses and staff working in clinical wards, intensive care units and operating theaters. The most common types of accidents were needlestick injuries and accidents due to improper handling of contaminated sharp devices or occuring while cleaning instruments or by coming into contact with blood through damaged skin or through the conjunctiva/mucous membranes.

Occult hepatitis C virus infection in candidates for liver transplant with cryptogenic cirrhosis

BACKGROUND

Occult hepatitis C virus (HCV) infection is a new entity described by the presence of HCV-RNA in liver biopsy and/or peripheral blood mononuclear cell (PBMC) specimens, and undetectable levels or absence of HCV-RNA and in the absence or presence of anti HCV antibodies in plasma by current laboratory methods.

OBJECTIVES

To evaluate the detection of HCV-RNA in PBMC specimens of the liver transplant candidates with cryptogenic cirrhosis by reverse transcriptase-nested polymerase chain reaction (RT-nested PCR).

PATIENTS AND METHODS

From November 2007 to March 2013, 45 patients from Liver Transplant Center of Imam Khomeini Hospital, Tehran, were enrolled in this cross sectional study. PBMC specimens were separated from the peripheral blood sample. After extraction of RNA from plasma and PBMC specimens, HCV-RNA status was tested by RT-nested PCR. The 5'-untranslated region (5'-UTR) genotyping of HCV-RNA amplified from PBMC specimens was performed by a standard methodology with the INNO-LiPA(TM) HCV II kit. The PCR products of 5'-UTR were sequenced after cloning into the pJET1.2 / blunt cloning vector.

RESULTS

Of 45 patients, 4 (8.9% [95% CI: 4.4-15.6]) had detectable genomic HCV-RNA in their PBMC specimens. HCV genotypes were determined in the PBMCs of these subjects showed that 2 (50.0%) subjects with occult HCV infection had HCV subtype 3a, and 2 (50.0%) had HCV subtype 1b.

CONCLUSIONS

This study found that 8.9 % of the Iranian candidates for liver transplant with cryptogenic cirrhosis had occult HCV infection. Therefore, designing prospective studies focusing on the diagnosis of occult HCV infection in these subjects prior to liver transplantation could be valuable.

Occupational exposure to blood-borne pathogens in a tertiary hospital: benchmarking using patient days

Incidence and risk factors for occupational exposure to blood-borne pathogens (OEBBPs) in a tertiary hospital in Saudi Arabia was assessed. Reported sharps injuries from 2009 to 2010 were analyzed and benchmarked using patient days. OEBBPs caused by sharps injuries increased from 41 in 2009 to 65 in 2010, with an incidence rate of 4.09/10 000 patient days in 2009 and 5.9/10 000 patient days in 2010. Most episodes (41%) occurred during recapping of hollow bore needles after obtaining blood specimens. The highest incidence was among nursing staff(n/N = 87/106; 82%), and injuries also occurred in housekeeping staff (3.7%). A correlationbetween morning shift and OEBBPs was observed, and the highest number of episodes occurred in the emergency room (21.5%) and renal dialysis unit (16.9%). There was exposure to HCV (n = 13) and HBV (n = 4) but not to HIV (n = 0), and no seroconversions were documented. Education on adherence to universal precaution measures and use of safety engineered devices as well as the introduction of an OEBBP notification hotline are recommended.

Factors affecting occupational exposure to needlestick and sharps injuries among dentists in Taiwan: a nationwide survey

Background

Although the risks of needlestick and sharps injuries (NSIs) for dentists are well recognized, most papers published only described the frequency of occupational exposure to NSIs. Less has been reported assessing factors contributing to exposure to NSIs. The purpose of this study was to update the epidemiology of NSIs among dentists in Taiwan and identify factors affecting NSIs in order to find preventive strategies.

Methodology/Principal Findings

A nationwide survey was conducted in dentists at 60 hospitals and 340 clinics in Taiwan. The survey included questions about factors supposedly affecting exposure to NSIs, such as dentist and facility characteristics, knowledge and attitudes about infectious diseases, and practices related to infection control. Univariate and multivariate logistic regression analyses were conducted to determine the association between risk factors and exposure to NSIs. In total, 434 (74.8%) of 580 dentists returned the survey questionnaires, and 100 (23.0%) reported that they had experienced more than one NSI per week. Our data showed that the risk of occupational NSIs is similarly heightened by an older age (odds ratio [OR], 3.18; 95% confidence interval [CI], 1.62–6.25), more years in practice (OR, 2.57; 95% CI, 1.41–4.69), working in clinics (OR, 1.73; 95% CI, 1.08–2.77), exhibiting less compliance with infection-control procedures (OR, 1.82; 95% CI, 1.04–3.18), having insufficient knowledge of blood-borne pathogens (OR, 1.67; 95% CI, 1.04–2.67), and being more worried about being infected by blood-borne pathogens (OR, 1.82; 95% CI, 1.05–3.13).

Conclusions/Significance

High rates of NSIs and low compliance with infection-control procedures highly contribute to the chance of acquiring a blood-borne pathogen infection and threaten occupational safety. This study reveals the possible affecting factors and helps in designing prevention strategies for occupational exposure to NSIs.

Percutaneous exposure incidents in nurses: Knowledge, practice and exposure to hepatitis B infection: Percutaneous exposure incidents in nurses

BACKGROUND

Nurses are at risk of percutaneous exposure incidents (PEIs), which may lead to serious or even fatal blood-borne infections.

OBJECTIVES

To determine the prevalence of PEIs in the last year, among nurses and to assess their knowledge about and frequency of safe method of practice in exposure to blood-borne pathogens (especially, to HBV).

MATERIALS AND METHODS

A cross-sectional study in 2008 was conducted on 138 nurses working in general surgery and obstetrics/gynecology services of Qazvin University of Medical Sciences, Qazvin, Central Iran. A questionnaire for assessment of risk factors for contracting HBV infection was completed by nurses.

RESULTS

Overall, the prevalence of needle stick injury (NSI) and direct exposure to body fluids were 52.9% (95% CI: 44.5%-61.3%) and 65.4% (95% CI: 57.4% - 73.8%), respectively. There was no statistically significant difference between the two studied centers in terms of sharp injuries; however, the rate of repeated NSI (number per each year ≥3) and mucocutaneous exposures were significantly higher in the general surgery ward. The overall coverage of vaccination in the two studied centers was 96.3%, but the rate of accurate answers to many questions pertaining to knowledge and practice were less than 50%.

CONCLUSIONS

Nurses are still at significant risk for developing NSI and mucocutaneous exposure. Continuous educational programs (especially by highlighting the seriousness of the problem) are necessary for improving this situation because inadequate education might increase unsafely practice.

Vírus da hepatite B: avaliação da resposta sorológica à vacina em funcionários de limpeza de hospital-escola

A hepatite viral B constitui um dos mais importantes problemas de saúde pública em todos os continentes. O vírus da hepatite B se transmite por via parenteral e, sobretudo, por via sexual. O objetivo foi avaliar a população ativa dos funcionários de limpeza do hospital da Faculdade de Medicina de Botucatu-UNESP, que receberam esquema completo de vacinação contra a hepatite B, medir os níveis de anticorpo contra o AgHBs (anti-HBs) e avaliar a sua relação com as condições epidemiológicas gerais, de vida pessoal e profissional e de risco de infecção pelo vírus da hepatite B.
