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.

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.

Needlestick and sharps injuries among healthcare workers in an oncology setting: a retrospective 7-year cross-sectional study.

OBJECTIVE: To assess the prevalence of needlestick and sharps injuries (NSSIs) and associated factors among healthcare workers (HCWs) at King Hussein Cancer Centre (KHCC), Amman, Jordan. METHODS: This retrospective cross-sectional study undertook a chart review of all HCWs that reported an NSSI between January 2015 and December 2021. Data collected included sociodemographic factors including age, sex, qualifications, and predictors of NSSIs such as working hours, work shift, and specific job roles within the oncology setting, work experience in KHCC, overall work experience and occupational category. RESULTS: A total of 355 NSSIs were included in this study with a peak prevalence in 2019 (81 of 355; 22.8%). Nurses (220 of 355; 62.0%), housekeeping staff (59of 355; 16.6%) and physicians (45 of 355; 12.7%) were the most affected occupations. NSSIs were most common in the surgical floor (65 of 355; 18.3%) and operating rooms (56 of 355; 15.8%). Blood collection (94 of 355; 26.5%) and waste collection (65 of 355; 18.3%) were the two primary procedures resulting in NSSIs. The risk of injury was significantly associated with the locations of NSSIs, procedure that caused NSSIs, shift and overall experience. CONCLUSION: NSSIs remain common among HCWs, which highlights the need for targeted education.

The Prevalence of Occupational Accidents and the Associated Factors Among Janitorial Staff at a University Teaching Hospital in South Ethiopia.

Background: The healthcare industry is widely regarded as a high-risk environment for workers' occupational health and safety. As a result, healthcare workers are constantly exposed to a wide range of hazards, including biological, chemical, physical, ergonomic, and psychosocial hazards. Consequently, janitorial staff are the most vulnerable section of the healthcare workforce to occupational injuries when compared to others due to the nature of their work. Therefore, this study aims at assessing the magnitude of occupational accidents and associated factors among Janitorial staff at Dilla University Teaching Hospital. Methods: This cross-sectional institutional-based study was conducted from August to September 2022 at a University Teaching Hospital in South Ethiopia. A total of 105 janitorial staff were included in the study with a response rate of 93.8%. The data were collected using a structured interviewer-administered questionnaire. Data were entered using Epi Info version 7.2.5 and exported to IBM SPSS statistics 22 for further cleaning and analysis. The binary logistic regression model was used to identify predictors of occupational accidents and variables with a p-value of <0.05 during the multivariable analysis were considered statistically significant. Results: The prevalence of occupational accidents is 61% (95% CI: 51.4, 70.5). Of the total study participants, 52 (45.5%) and 33 (31.4%) of the participants had reported that they have experienced chemical splash and needle stick injury, respectively. The age of participants was one of the factors for occupational accidents. The participants who did not receive training were 3 times [AOR=2.9, 95% CI (1.04, 8.02)] more likely exposed. Having good practice was protective against occupational injuries. Conclusion: The study highlights the high prevalence of occupational accidents, particularly chemical splashes, and needle stick injuries, among janitors in the study settings. The study emphasizes the importance of age, training, awareness, and adherence to infection prevention and control strategies as factors influencing the likelihood of experiencing occupational injuries.

Needle-Stick Injuries in Ophthalmic Practice.

Purpose: Needle-stick injuries (NSI) are a prominent route by which blood-borne infections are transmitted. The unique microsurgical nature of ophthalmic practice constitutes an additional risk to sustain injury. This study aimed to identify the epidemiological profile of needle-stick injuries in a tertiary eye center and to evaluate the implemented safety policy in preventing sharp injuries. Methods: This was a retrospective cross-sectional study of all sharp injuries that occurred at King Khalid Eye Specialist Hospital (KKESH). Data on all reported sharp injury incidents from 2013 to 2021 were collected. The mechanisms of injury, context, location, and type of prick were collected and analyzed. Also, this study involved an institution-based survey for all ophthalmic staff. Results: Two hundred and one sharp injury incidents were reported over 9 years. Physicians sustained 46.8% (n=94) of injuries, followed by nurses and ophthalmic technicians, 40.8% (n=82) and 7% (14); respectively. Operating and treatment rooms were the locations of 60.7% of incidents, whereas outpatient clinics and emergency rooms accounted for 19.4% and 13.4% of injuries, respectively. Conclusion: The current findings add to the growing body of literature on the importance of NSI prevention and reporting strategies. In the present study, sharp injuries were most commonly encountered by ophthalmic staff in the operating rooms. Continuous staff education on handling sharp instruments, encouraging anonymous reporting, and up-to-date revisions of guidelines and policies are of paramount importance to lessen the burden of sharp injuries.

Evaluating occupational exposures of dental nurses: A retrospective study.

Objective: The objective of this study was to investigate occupational blood-borne pathogen exposure among dental nurses and their attitudes toward infected patients, as well as the effectiveness of the training course, to provide a scientific basis for improving the quality of safety management in the dental hospital. Materials and methods: The study was conducted using questionnaires administered from November 2019 to December 2019 in three hospitals in Sichuan Province, China. Frequencies for answers were calculated and presented as percentages. Results: In total, 257 valid questionnaires were returned. Most (61.9%) nurses stated that they were involved in occupational exposure. Among them, 154 had experienced sharp injuries, and the syringe needle was the most common instrument for injuries (45.8%). Twenty-two individuals had mucosal exposure, and the proportion of eye exposure was the highest (90.9%). Only associations between training and mucosal membrane exposure were found; however, the relevance was weak (r = 0.141). Of the participants, 86.4% felt morally responsible for taking care of patients with infectious diseases, and most (92.6%) said they would continue with this career. Conclusion: Occupational exposure, particularly to sharp injuries, was common in medical care among dental nurses; however, vocational training had little effect on their incidence. As dental nurses still have positive attitudes toward patients with infectious diseases, more effective training should be conducted.

Prevalence of needle-stick injury among nursing students: A systematic review and meta-analysis.

Introduction: Needle-stick injuries (NSI) are a serious threat to the health of healthcare workers, nurses, and nursing students, as they can expose them to infectious diseases. Different prevalence rates have been reported for this type of injury in different studies worldwide. Therefore, this study aimedto estimate the pooled prevalence of NSI among nursing students. Methods: This study was conducted by searching for articles in Web of Science, PubMed, Scopus, Embase, and Google Scholar without time limitation using the following keywords: needle-stick, needle stick, sharp injury, and nursing student. The data were analyzed using the meta-analysis method and random-effects model. The quality of the articles was evaluated with Newcastle-Ottawa Quality Assessment Scale (NOS). The heterogeneity of the studies was examined using the I 2 index, and the collected data were analyzed using the STATA Software Version 16. Results: Initially, 1,134 articles were retrieved, of which 32 qualified articles were included in the analysis. Nursing students reported 35% of NSI (95% CI: 28-43%) and 63% (95% CI: 51-74%) did not report their needle-stick injuries. The highest prevalence was related to studies conducted in Asia (39.7%; 95% CI: 31.7-47.7%). There was no significant correlation among NSI prevalence and age of samples, and article year of publication. Conclusion: A third of nursing students reported experiencing NSI. Consequently, occupational hazard prevention training and student support measures need to be considered.

Risk Factors Associated with Defaulted Follow-Up and Sharp Injury Management among Health Care Workers in a Teaching Hospital in Northeastern Malaysia.

Sharp injury is a serious occupational risk for healthcare workers (HCWs). This study aimed to determine the distribution and associated factors of sharp injury cases among HCWs working at a teaching hospital in northeastern Malaysia. This was a retrospective cohort study on all reported sharp injury cases from 2015 to 2020. The secondary data were examined using descriptive and multiple logistic regression. Statistical significance was determined for associated factors of HCWs who did not attend immediate treatment after a sharp injury or any of the subsequent follow-up variables, with a p-value of less than 0.05. A total of 286 cases fulfilled the study criteria. The mean (SD) age of sharp injury was 29.4 (5.38) years. The overall defaulted rate for follow-up was 51.4%. Multiple logistic regression revealed a significant relationship between defaulted follow up on sharp injury management and job category as well as the type of device used. Being a doctor (Adj OR 2.37; 95% CI: 1.40, 4.03; p = 0.010) and those using other sharp instruments such as Coupland and drip sets (Adj OR 4.55; 95% CI: 1.59, 13.02; p = 0.005) had a higher odds to default follow up on sharp injury management. In conclusion, although there is a link between defaulting the follow-up and both the work category and the type of device that caused the injury, a deeper analysis is needed to uncover any additional factors and determine the appropriate intervention strategies to ensure follow up adherence.

Increased Bloodborne Pathogen Exposure Hotline Utilization During the COVID-19 Pandemic: An Unexpected Phenomenon.

Background: Mitigating bloodborne pathogen exposure (BBPE) risk among healthcare workers is a major focus of hospital-based occupational health programs. The COVID-19 pandemic has placed added demands on occupational health services for healthcare workers. Its impact on BBPE incidence is unreported. Methods: As part of quality improvement efforts, we examined BBPE case incidence at two affiliated health centers during a 24-month period, 12 months preceding and following the COVID-19 pandemic onset. We used Year 1 to Year 2 change in incidence at the larger health center as the referent value to generate predicted incidence rates at the study health center. We tested the ratio of observed to predicted values at the study health center as a Poisson variable to its expectation. We defined a BBPE consistent with the Occupational Safety and Health Administration (OSHA) Bloodborne Pathogens Standard. Results: The BBPE case incidence at Health Center One (HC1), totaled 46 cases in Year 1, increasing 19% to 55 cases in Year 2. The cumulative incidence at Health Center Two (HC2), the referent facility, was 664 cases in Year 1, declining 24% to 503 in Year 2. The ratio of 55 events at HC1 to the expected incidence of 35, based on the experience at HC2, was 1.6 (p < .05). Discussion/Applications to Practice: The incidence of BBPE events at HC1 paradoxically increased during the COVID-19 pandemic, contrasting to the expected decrease that we observed at HC2. These data suggest that during times of increased stress to employee healthcare delivery from an infectious disease outbreak, the burden of ongoing practice demands may increase.

[Prevalence of sharp instrument injuries among medical staff in a tertiary general hospital].

Objective: To investigate the current situation of sharp instrument injuries among medical workers in a tertiary general hospital in Fuzhou, so as to provide basis for formulating relevant policies. Methods: In June 2019, medical personnel working in a tertiary general hospital in Fuzhou, who may have sharp instrument injuries were selected as the research object. A total of 2720 questionnaires were received, including 2688 valid questionnaires, with an effective rate of 98.8%. The age, type of work, professional title, working years, operating habits, occurrence and reporting of sharp instrument injuries among medical staff from June 2018 to May 2019 were investigated. Results: The incidence of sharp instrument injury was 37.6% (1011/2688) . Among them, 20.6% (208/1011) had multiple sharp instrument injuries. The exposure rate of contaminated sharp instruments was 15.1% (405/2688) . With the increase of age, professional title and working years, the incidence of sharp instrument injury decreased year by year (χ(2)(trend)=12.393, 33.339, 15.160, P<0.05) . The first three causes of sharp instrument injury were breaking glass ampoules by hand (39.1%, 395/1011) , extracting liquid medicine (10.4%, 105/1011) and handling sharp instruments by hand (10.3%, 104/1011) . The main sharp instruments causing sharp injury were ampoules (43.2%, 437/1011) , syringe needles (20.3%, 205/1011) and suture needles (9.6%, 97/1011) . 874 (86.4%) medical staff had missed reports after sharp instrument injuries. Conclusion: The occurrence of sharp instrument injury in this hospital is still serious, and the protection of sharp instrument injury should be strengthened.

Frequency of Occupational Bloodborne Infections and Sharps Injuries among Polish Paramedics from Selected Ambulance Stations.

To evaluate the prevalence of bloodborne infections (BBIs) and assess the incidence and selected risk factors for sharps injuries (SIs), a cross-sectional serosurvey was performed between December 2018 and October 2019 among 286 paramedics (76.5% males; mean age, 37 years) from 17 randomly selected ambulance stations in the West Pomeranian region of Poland. An ELISA system was used to detect anti-HBc, anti-HCV, and anti-HIV. HBV vaccination uptake was 95.6%; 7.3% (95% CI: 4.6-11.0%) paramedics were anti-HBc positive, and anti-HCV/anti-HIV seropositivity was not reported. Almost one-fourth of paramedics reported having had ≥1 SI during the preceding year (Me = 6.0, range 1-100). Most recent exposures primarily took place during an emergency procedure (76.7%), in an ambulance (45.2%), caused by hollow-bore needles (73.8%), and were not reported (50.0%). Additionally, 52.2% of paramedics reported needle recapping, and 52.6% did not use safety engineered devices (SEDs) at work. Mean knowledge score was low (2.6 ± 1.7); 3.4% had never participated in infection-control (IC) training, and those not trained were more likely to suffer a SI (odds ratio (OR) 4.64; p = 0.03). Due to frequent SIs, of which half are unreported, paramedics remain at risk of acquiring occupational BBIs. SI risk could be reduced by providing training on IC procedures, ensuring better compliance with safe work practices, and supplying more SEDs.

The Prevalence of Needlesticks and Sharp Injuries, and the Associated Factors Among Midwives and Nurses in North Wollo Zone Public Hospitals, North East Ethiopia: An Institution-based Cross-sectional Study.

BACKGROUND: Health professionals are at high risk of exposure for needlestick or sharp injury due to repeated exposure in clinical areas. This exposure leads to the acquiring of different infectious diseases like human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and other infectious diseases. Nurses and midwives having repeated exposure due to long working time, not wearing personal protective equipment, less work experience, and who are unable to apply infection prevention utilization guidelines are at high risk of needlestick and sharp injuries. METHODS: An institutional-based, cross-sectional study design was conducted in North Wollo Zone public hospitals. A simple random sampling technique was applied to select study subjects. The method of data collection was self-administered questionnaires that are structured and pretested from February to March 2019. The data were analyzed using both descriptive and analytical statistics. Binary logistic regressions were used to test the association between variables. Then, P-value <0.05 was considered as statistically significant in this study. RESULTS: Of the 147 respondents who participated in the study, 50.3% were female and 49.7% were male. The prevalence of needlestick and the sharp injuries was 75.5%. Recap practice of needle (AOR: 3.880; 95%CI: 1.666-9.036), working room (maternal care room) (AOR: 2.968; 95%CI: 1.012-8.703), and contagious room like emergency room (AOR: 3.587; 95%CI: 1.383-9.301) are significantly associated with needlestick and sharp injuries. CONCLUSION: This study showed that three-quarters of the study subjects were exposed to needlestick injury at least once in the past year. Needle recapping practice and working room were associated with needlestick and sharp injuries. Then, health personnel should avoid the practice of recapping a needle and tale care themself to avoid needle and sharp injuries in the workplace.

Cross-sectional study assessing the risk of needlestick injury from an insulin pen among nursing care providers.

OBJECTIVE: Needlestick injuries caused by insulin pen injection are a serious occupational hazard for health care workers in China. We evaluated the prevalence of stick injuries with insulin pen injection and identified associated risk factors. METHODS: This cross-sectional survey was conducted from 1 October to 30 November 2018 in two tier three hospitals in Chongqing, China. Self-administered questionnaires were developed by the Chinese Nursing Association Diabetes Care Special Committee. We analyzed associations between potential risk factors and injuries at different operational steps. RESULTS: A total 233 of 302 (77%) participants (mean age 28.5±5.3 years) reported a needlestick incident. Most respondents (49%) had 3 to 10 years' working experience and had received injection safety training. Most needlestick injuries occurred while recapping needles after injection. The risk of injury was significantly associated with department and job position. The injury rate increased with increased number of years worked. Respondents with ≥10 years working experience reported the highest needle-capping injury rate (88%): odds ratio 1.93, 95% confidence interval, 1.01 to 3.69. CONCLUSION: Recapping needles after injection showed the highest risk for stick injury with an insulin pen. Nurses in the surgery department and those with longer work histories were more likely to be injured.

Magnitude of Needlestick and Sharp Injury and Its Associated Factors Among Nurses Working at Health Institutions in Western Ethiopia, 2020.

BACKGROUND: Needlestick and sharp injury represent a major occupational hazard in the healthcare environment with nurses experiencing a large proportion of the burden. It is a potential for transmission of bloodborne pathogens including the human immunodeficiency virus, hepatitis B and C virus. Needlestick and sharp injuries are neglected and are often not reported. Few studies have been conducted in Ethiopia, and no study was conducted particularly in the Western part of a country. Therefore, this study aimed to assess needlestick and sharp injuries and associated factors among nurses working at health institutions in western Ethiopia, 2020. METHODS: An institutional based cross-sectional study was conducted on 297 nurses, from January 15 to 30, 2020. The study participants were selected by a simple random sampling method and data were collected using a self-administered questionnaire. Multivariable logistic regression was used to identify associated factors of needlestick and sharp injury. The association between needle stick and sharp injury and associated factors were measured using the odds ratio at a 95% confidence interval. The statistical significance was made at a p-value of less than 0.05. RESULTS: Out of 297 nurses who participated in the study, 100 (33.7%) had encountered needlestick and sharp injury in the past 12 months. Recapping the needle (AOR=3.99 95% CI: 2.20, 7.21), non-utilization of infection prevention guideline (AOR= 2.69, 95% CI: 1.29, 5.60), not taking injection safety training (AOR = 2.25, 95% CI: 1.22, 4.13) and having job-related stress (AOR= 1.93, 95% CI: 1.10, 3.41) were significantly associated with the needlestick and sharp injury. CONCLUSION: In this study, the magnitude of needlestick and the sharp injury was high. The nurse should not recap the needles, should utilize infection prevention guidelines, should minimize stress, and routine injection safety training should be given to minimize needlestick and sharp injuries.

Knowledge and awareness regarding occupational needle stick and sharp injuries among dental personnel in Malaysia.

BACKGROUND: Accidental occupational injuries increase the risk of communicable diseases like hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) among dental personnel. Such occupational injuries affect healthcare quality by enhancing dissatisfaction and lack of motivation to work among dental personnel. OBJECTIVE: The present study aims to assess knowledge and awareness regarding needle stick and sharp injury among dental personnel and compared the knowledge and awareness level about needle stick injuries between dental professionals and dental supporting staff working at the School of Dental Sciences, Universiti Sains Malaysia. METHODS: This cross-sectional study was conducted from March 2016 to March 2017. The total sample included 112 registered dental personnel including dental professionals (lecturers, dental officers, and postgraduate students) and dental supportive staff (including staff nurses and dental surgery assistant) who were selected from the School of Dental Sciences, Universiti Sains Malaysia at Kelantan District of Malaysia. Data were collected by a structured questionnaire. RESULTS: In our study 60.7% respondents answered correctly for all the statements regarding knowledge and 51.8% of the respondents answered correctly for the statements regarding awareness on needle stick and sharp injury. No significant difference of knowledge level has been observed between the dental professionals and dental supportive staff (p < 0.819), whereas the awareness level was significantly different between these two groups (p < 0.016). CONCLUSIONS: There is a difference regarding awareness level on needle stick and sharp injury between dental professionals and dental supportive staff in our study but no differences were found in knowledge level between two groups.

The Influence of Knife Sharpness on Forearm Wounds in Knife Slash Cases / 医用生物力学

Objective To quantitatively explore the influence of knife sharpness on forearm wounds in knife slash cases. Methods The finite element models of the upper limb and knives with 3 degrees of sharpness (with sharp blade, blunt blade, wide blade) were developed based on human CT images and prototype of slash knife. The slash by 3 kinds of knives on the forearm at velocity of 4 m/s and duration of 10 ms was simulated, so as to analyze changes in contact forces, wound dimensions and energy. Results During the slash by knives with sharp, blunt, wide blade, the blades reached the ulna at about 65, 85, 95 ms, respectively. The corresponding slash forces were 846, 1 064 and 1 865 N; the wound lengths were 135.64, 105.47 and 99.23 mm; the wound depths were 38.77, 27.81 and 18.74 mm. With the sharpness of blade decreasing, the wound formation was slowed, the length and depth decreased and the slash force increased. The model system for slash knife with sharp blade had obviously greater total energy and inner energy, but smaller kinetic energy, compared with slash knife with blunt blade and wide blade. Conclusions The method for quantitatively assessing wound formation in knife slash upon the forearm was developed. The research findings deepen the understanding of biomechanical mechanism of wound formation by knife slash, and provide new scientific means for forensic investigation and court trial of knife slash cases.

Assessment of needle stick and sharp injuries among health care workers in central zone of Tigray, northern Ethiopia.

OBJECTIVE: Accidental occupational injuries to health care workers (HCWs) continue to have a significant problem in the healthcare system. Thus, the aim of this study was to assess prevalence of needle sticks and sharp injury and associated factors among health care workers working in Central Zone Tigray northern Ethiopia. RESULT: The prevalence of needle stick and sharp injury in the past 12 months preceding the study and entire job were 25.9% and 38.5% respectively. Nearly one-third (31%) of the injuries occurred in emergency unit and 122 (71.3%) of the materials caused injury were used on patients. Practice of needle recap, ever used cigarette in last 12 months, training, work hours > 40 per week, job dissatisfaction and work experience less than 5 years were found factors significantly associated with needle stick and sharp injury for health care workers. The magnitude of Needle stick and sharp injury is high in the study area. Policy makers should formulate strategies to improve the working condition for healthcare workers and increase their adherence to universal precautions.

Epidemiology of needlestick and sharp injuries among health care workers based on records from 252 hospitals for the period 2010-2014, Poland.

BACKGROUND: Needlestick and sharp injuries (NSIs) are an important element of public health and should be closely monitored. On the other hand there are no precise Polish data on a number of the occupational NSIs. The aim of the study was to assess the failure to report injuries and then to estimate the actual number of NSIs among healthcare workers (HCWs) in Poland based on the collected data. METHODS: Analysis of injury registers on the basis of 252 hospitals in Poland. Conducting 487 surveys among doctors, nurses and paramedics. Calculation of rates of injuries per 1000 workers per year (with 95% confidence intervals (CI)). The level of statistical significance was set at p ≤ 0.05. RESULTS: In the study period, 9775 NSIs were registered in the hospitals. Majority of the NSIs were recorded among nurses (72.6%,p < 0.01). The needle was the tool responsible for the greatest number of the NSIs in all professional groups (79.5%, p < 0.01). The average annual NSIs rates based on hospital registers were: 16.0/1000 doctors, 20.5/1000 nurses, 16.8/1000 paramedics. Every second NSIs was not reported (45.2%). We estimated that there are probably 13,567 NSIs every year among hospital care workers in Poland. CONCLUSIONS: NSIs are a significant health problem for HCWs and should be subject to epidemiological surveillance. The purpose of the training of medical personnel should be to increase the number of injuries reported. The implementation of the epidemiological surveillance system will allow for the unification of the obtained data, which would be more comparable on the national scale as well as between different countries.

Behaviors and Attitudes of Polish Health Care Workers with Respect to the Hazards from Blood-Borne Pathogens: A Questionnaire-Based Study.

Blood-borne infections represent an important occupational health issue in health care settings. The aim of this study was to analyze behaviors of health care workers (HCWs) in the field of needlestick injuries (NSIs) as well as to learn about their attitudes to patients infected with blood-borne viruses. A total of 487 HCWs based at 26 hospitals in Poland completed an anonymous self-administered questionnaire in the period of October⁻December 2015. Data was analyzed using descriptive statistics and multiple logistic regression. Of the HCWs, 44.8% suffered superficial wounds, and 17.9% HCWs were cut deeply at least once. The most frequent causes of injuries were: rush (31.4%), unpredictable patient behavior (29%), and lack of attention (27%). The rate of underreporting NSIs was 45.2%. Males showed more than three times higher chance of not reporting injuries (odds ratio (OR) 3.495, 95% Confidence Interval (CI): 1.65⁻7.49). The nurses more often took off their protective gloves to make the procedure easier (p = 0.036).
