Combatting the occurrence of needle-stick injuries in a medical school: why is it still an issue?

BACKGROUND: Needle-stick injuries (NSIs) pose a safety risk for healthcare workers with great potential for serious infections. The aim was to determine numbers and causes of NSIs as well as the frequency with which medical students report NSIs in the final stages of study. METHODS: An online questionnaire was developed and made available in January and February 2023 to all undergraduate medical students (n = 423) in the last 1.5 years of their degree course at Würzburg University, Germany. RESULTS: The response rate was 19.6% (n = 84). Among respondents, 27.4% (n = 23) reported at least one NSI. Occurrence was particularly frequent in surgery, obstetrics and gynaecology, and internal medicine. Assisting with procedures, suturing, and blood sampling were considered high-risk activities. Lack of concentration, distraction, and time pressure played a role in incidents. Respondents did not report 18.8% of NSIs with the main reasons being fear of the consequences, self-assessment of the injury as minor, or the opinion of supervisors that reporting was unnecessary. Students with previous practice on simulators or patients were significantly more likely to suffer NSIs. Instructions from occupational health specialists beforehand correlated with fewer NSIs. CONCLUSION: We assume that trained students are more experienced in handling invasive procedures, leading to a greater adoption of corresponding activities and thus an increased risk of injuries in absolute numbers. This does not counter the need for didactic interventions prior to workplace-based training to raise awareness of NSI risks. Simultaneously, concepts must be developed and implemented to support reporting and alleviate fears regarding consequences.

A Cross-Sectional Analysis of Sharps Injuries Among Dermatologic Surgeons: A Survey of American College of Mohs Surgery Members.

BACKGROUND: There is a paucity of data on sharps injuries and bloodborne pathogen exposure among Dermatologic Surgeons. OBJECTIVE: Quantify occupational risks from sharps injuries among Mohs surgeons. Determine rate of injury, reporting, and confidence in staff's sharps handling. METHODS: A cross-sectional analysis performed using survey responses from Mohs surgeons with membership in the American College of Mohs Surgery (ACMS). RESULTS: A total of 60 ACMS members completed the survey. Overall, 56.7% reported at least 1 sharps injury within the past year, of which 14.7% resulted in a bloodborne exposure (odds of exposure: 7.5% per year). The most common type of injury was self-inflicted suture needlestick (76.5%). Forty-four-point-one percent did not report their injuries. Ninety-five percent reported access to postexposure prophylaxis at their workplace. In addition, respondents in academic and single-specialty practices were more likely to report high or moderate confidence in staff sharps handling knowledge and in injury reporting compared with respondents from multispecialty and solo practices (88% vs 54% p = .02, 76%-81% vs 27% p = .0004, respectively). CONCLUSION: Sharps injuries and under-reporting of these injuries are common among Mohs surgeons. Despite reporting of higher confidence in staff knowledge and training in academic and single-specialty practices, there was no correlation with surgeon's rate of injury.

Global prevalence of needle stick injuries among nurses: A comprehensive systematic review and meta-analysis.

BACKGROUND: Nurses usually provide direct patient care. However, they account for the majority of healthcare workers (HCWs) injured by needles or other sharp objects. OBJECTIVES: To assess the prevalence of needle stick injuries (NSI) among nurses worldwide; according to WHO regions, the socioeconomic development index (SDI) of countries, and the developmental status of individual countries, and in the Middle East. DESIGN: Systematic review and meta-analysis. METHODS: We searched PubMed, Scopus, and Web of Science databases. We calculated the pooled NSI prevalence estimates using a random-effect meta-analysis with the Comprehensive Meta-Analysis software. The report of the study was in accordance with the PRISMA 2020 statement. RESULTS: The overall worldwide NSI prevalence pooled from our analysis was 40.97% (95% confidence interval [CI]: 31.29-50.63%, p = .00001). A subgroup analysis of NSI prevalence according to WHO regions revealed the highest prevalence in Southeast Asia (49.9%, 95% CI: [23.4-76.3%]) and the lowest in the United States of America (25.1%, 95% CI: [18.1-32.1%]), respectively. The pooled prevalence in developed and developing countries was 30.5% (95% CI: 27.3-33.8%) and 46.6% (95% CI: 33.7-59.5%), respectively. According to the SDI, NSI prevalence was highest in low-middle SDI countries (48.9% [95% CI: 30.7-67.2%]). CONCLUSION: Our results showed a high NSI prevalence among nurses worldwide. Developing countries had a significantly higher NSI prevalence than developed countries, especially low-middle SDI countries. RELEVANCE TO CLINICAL PRACTICE: This study highlighted the prevalence of NSI risk among nurses practising in clinical settings worldwide. The study findings suggest that continuous training programs should be implemented for nurses to enhance their knowledge, performance and attitude toward NSI prevention in clinical settings. NO PATIENT OR PUBLIC CONTRIBUTION: Contributions from patients or the public are irrelevant because the purpose of this study was to examine the global prevalence of NSIs in nurses.

Prevalence and characteristics of needlestick injuries among dental interns during their first-year clinical training: an observational study.

BACKGROUND: Dental interns are vulnerable to needlestick injuries (NSI). The objectives of this study were to examine the prevalence and characteristics of NSI exposures among dental interns during their first-year clinical training, assess risk factors, and evaluate reporting behaviours. METHODS: An online survey was conducted among dental interns of Class 2011-2017 at Peking University School and Hospital of Stomatology (PKUSS), China. The self-administrated questionnaire consisted of information on demographic profiles, NSI characteristics, and reporting practices. The outcomes were presented by descriptive statistics. A multivariate regression analysis was performed to assess NSI sources using a forward step-wise approach. RESULTS: A total of 407 dental interns completed the survey (response rate 91.9%, 407/443), and 23.8% sustained at least one NSI. The mean number of NSIs per intern was 0.28 during the first clinical year. More occupation exposures occurred from October to December, between 13:00-15:00. Syringe needles were the most frequent sources, followed by dental burs, suture needles, and ultrasonic chips. The risk of peer-inflicted NSIs in the department of Paediatric Dentistry was 12.1 times higher than that in Oral Surgery (OR 12.1, 95% CI: 1.4-101.4). Appropriately 64.9% NSIs occurred when chairside assistants were absent. Compared to working alone, the risk of peer-inflicted NSIs was 32.3 times higher when providing chairside assistance (OR 32.3, 95% CI: 7.2-145.4). The left-hand index finger was the most commonly injured site. About 71.4% of exposures were reported in paperwork. CONCLUSIONS: Dental interns are susceptible to NSIs during their first-year clinical training. Extra attention should be paid to syringe needles, dental burs, suture needles, and ultrasonic chips. The lack of chairside assistance is hazardous regarding NSIs. The training of chairside assistance of the first-year dental interns should be enhanced. First-year dental interns are required to increase their awareness of ignored behaviors related to NSI exposures.

PREVALENCE AND RISK FACTORS OF NEEDLE STICK INJURIES AMONG CLEANERS IN A TERTIARY HEALTH FACILITY IN GOMBE, NORTHEAST, NIGERIA.

Introduction: The cleaning staff working in a health facility are at risk of needle stick injuries (NSI) because of the nature of their work which involves the disposal of used needles and sharps. This study aimed to determine the prevalence and risk factors of NSI among cleaning staff at Federal Teaching Hospital Gombe. Methodology: A cross-sectional study was carried out among 150 cleaning staff, selected using simple random sampling technique. An interviewer-administered questionnaire was used to collect data on the research variables. Data was analyzed using SPSS Version 23. Bivariate analysis was conducted to examine the relationships between sociodemographic factors and the prevalence of injury, while logistic regression was used to determine the predictors of needle stick injuries. Statistical significance was determined at a p-value of ≤0.05. Result: Majority of the respondents were males (64%) and uneducated (63.3%) with a mean age of 39.9±9 years. The prevalence of NSI among the cleaners was 35.3% with 23.3% having experienced injury at least once. Uneducated individuals were found to have experienced NSI more than those who were educated. Risk factors found to be predictors of NSI were sex, educational level, job duration of > 10 years, and number of hours spent during cleaning activity. Conclusion: Most of the staff were uneducated with no formal training before the commencement of work. Prevalence of NSI was high and therefore, there is a need for health education on the risks of the job and formal training of staff before commencement of work.

A program to improve the knowledge, attitudes, and practices of needle stick and sharps injuries through bundled interventions among nurses: An KAP Mode-Based Approach to Intervention.

Nurses face a greater risk of needle stick and sharp injuries (NSIs) because they do most of the injections and procedures with sharp instruments. The current study tested a program to improve nurses' knowledge, attitudes and practices on NSIs, three phases were included: Developing the Hospital Practice Standard, implementing a series of measures and implementing of quality supervision phases. It consisted of a bundle of interventions based on Knowledge-Attitudes-Belief-Practice (KAP-KABP) Model with a pretest-posttest design. We obtained a total of 656 (88.53%) completed pre-intervention questionnaires and 674 (92.97%) post-intervention ones. The number of trained participants on NSIs increased from 615 (93.7%) to 666 (98.8%), and reported of NSIs within 3 months decreased from 42 to 15 (2.2%) after the intervention. The total score of Knowledge of NSIs improved from 19.18 (SD = 1.31) to 19.42 (SD = 0.93) after training (Z = -4.025, P < 0.001), the Attitude was raised from 54.21 (SD = 4.09) to 55.24 (SD = 3.59) (Z = -5.261, P < 0.001), and the Practice increased from 89.28 (SD = 7.22) to 92.74 (SD = 7.22), with a P Value<0.05. The findings indicated the program can improve the nurses' knowledge and attitudes towards NSIs prevention. There is a statistically significant increase in the practice score and decrease in the incidence rate of NSIs after the intervention.

Foreign body ingestion in pediatric patients.

PURPOSE OF REVIEW: The purpose of this article is to review clinical manifestations and management of common pediatric foreign body ingestions, with a particular focus on some of the current trends. RECENT FINDINGS: Foreign body ingestion (FBI) is a problem that is frequently encountered by pediatric providers. As new toys and products enter the marketplace, there may also be new dangers from those objects not initially recognized. Some of the recent trends and findings in pediatric FBI include an increase in adolescent injury from ingestion of laundry detergent pods because of a popular game where participants are encouraged to bite or swallow the pods, and injuries associated with ingesting parts of a popular toy known as a 'Fidget Spinner'. SUMMARY: Adverse events resulting from FBI range the entire gamut from nonexistent or minor symptoms to moderate injury and rarely may be fatal. Factors such as age, type of object ingested, anatomic location of the foreign body, and timing from ingestion to receipt of medical attention all determine the risk posed to the child and guide management decisions. Because of the constant development of products, and the potential for the emergence of new and dangerous trends among children, continued surveillance by the medical community is important in monitoring and managing injuries associated with FBI.

The ability of a real-time injection pressure monitoring system to discriminate between perineural and intraneural injection of the sciatic nerve in fresh cadavers.

Injection pressure monitoring provides valuable information to prevent intraneural injections and possibly consequent nerve damage during peripheral nerve block. However, the measurement of injection pressure along the injection line is inaccurate as it is influenced by several variables. The aim of this study was to test a new system for precise injection pressure monitoring at the needle tip in a cadaveric model. The system consists of a miniaturised pressure sensor embedded within the needle shaft that is connected via an optical fibre to an external control unit. In order to test the capacity of the system to discriminate between perineural and intraneural injections, a total of 24 ultrasound-guided injections at various locations of the sciatic nerve (12 perineural and 12 intraneural) were performed in fresh cadavers. The injections were delivered at a constant rate by an electronic pump (5 ml saline at 10 ml.min-1 ). Two perineural and two intraneural injections were excluded from analysis, since the operator could not confirm the exact needle-tip location. Mean (SD) peak injection pressure was significantly lower for perineural compared with intraneural injections (14 (6) kPa vs. 131 (56) kPa; p < 0.001). This study shows that this system is a reliable method to accurately monitor injection pressure at the needle tip, allowing for discrimination between perineural and intraneural injections of the sciatic nerve in fresh cadavers.

OneShot-M: A New Device for Close Laparoscopy Pneumoperitoneum.

INTRODUCTION: The induction of pneumoperitoneum is the first and most critical phase of laparoscopy, due to the significant risk of serious vascular and visceral complications. The closed technique for the creation of pneumoperitoneum could lead to several surgical complications. The present study aimed to overcome the complications associated with the insertion of Veress needle, improving its use, and facilitating the rapid creation of pneumoperitoneum. METHODS: Thirty large white female pigs were enrolled in our study. A common plunger was modified in order to allow the passage of a 15-cm long Veress needle. This method was applied to 26 laparoscopic procedures (26 pigs) of several specialist branches. RESULTS: OneShot-M close laparoscopy pneumoperitoneum creation device allowed us to obtain pneumoperitoneum quickly in all attempts, without any intraoperative and postoperative complications related to the use of the Veress needle. CONCLUSION: The use of the proposed device showed an induction time as quick as the standard laparoscopic closed abdominal entry. The patented device is cheap and allows a safe abdominal entry. In addition, abdominal entry is much faster than the classic open technique.

Sharp injuries: a cross-sectional study among health care workers in a provincial teaching hospital in China.

BACKGROUND: The objectives of this study are to investigate the incidence and reporting behavior of sharp injuries among healthcare workers (HCWs) and identify the risk factors associated with these injuries. METHODS: A cross-sectional survey was conducted in February 2017 in a provincial teaching hospital in China. Data were collected from 901 HCWs using a self-administered questionnaire which included demographic information, experience, and reporting behavior of sharp injuries. Stepwise logistical regression was used to analyze the risk factors. RESULTS: HCWs (248 [27.5%]) had sustained a sharp injury in the previous year. Factors including seniority, job category, title, education, department, and training programs were associated with the occurrence of sharp injuries. According to the stepwise logistical regression, seniority, and training programs were the risk factors associated with the occurrence of sharp injuries. Of 248 sharp injuries, 130 HCWs were exposed to blood. Only 44 (33.9%) HCWs reported their injuries to the concerned body. The main reasons for not reporting the sharp injuries were as follows: perception that the extent of the injury was light (30.2%), having antibodies (27.9%), and unaware of injury (16.3%). CONCLUSIONS: Sharp injuries in the studied hospital were common and were likely to be underreported. Therefore, an effective reporting system and sufficient education on occupational safety should be implemented by the relevant institutions. Moreover, it is important to take effective measures to manage sharp injuries in HCWs and provide guidance for their prevention.

Displacement of a Broken Dental Injection Needle Into the Perivertebral Space.

Dental injection needle breakage is an uncommon problem in dental practice. Displacement of the broken fragment into anatomical spaces is, on the other hand, a serious complication that occurs most commonly during inferior alveolar nerve blocks as a result of material wear, incorrect application of the anesthesia technique, or sudden movement of the patient during injection. Further complications such as infection, trismus, and nerve paralysis may exacerbate the condition and, if not treated adequately, life-threatening conditions may develop over time as the fragment dislodges deeper in soft tissues. Clinical symptoms of the patient, as well as the findings gathered from detailed physical examination and radiographic evaluation, are important factors to consider before performing an exploratory surgery. Removal of a broken needle may be troublesome due to its proximity to vital anatomic structures. Multislice computed tomography is a reliable imaging modality that provides accurate information to pinpoint the exact location of the needle fragment.This report describes a case of needle breakage occurred during inferior alveolar nerve block which was performed to extract a third molar tooth and the migration of the broken fragment from the right mandibular ramus area into the perivertebral space, with special emphasis on the surgical retrieval technique with multiplanar computed tomography imaging guidance.

Lacerations and Embedded Needles Caused by Epinephrine Autoinjector Use in Children.

STUDY OBJECTIVE: Epinephrine autoinjector use for anaphylaxis is increasing. There are reports of digit injections because of incorrect autoinjector use, but no previous reports of lacerations, to our knowledge. We report complications of epinephrine autoinjector use in children and discuss features of these devices, and their instructions for use, and how these may contribute to injuries. METHODS: We queried emergency medicine e-mail discussion lists and social media allergy groups to identify epinephrine autoinjector injuries involving children. RESULTS: Twenty-two cases of epinephrine autoinjector-related injuries are described. Twenty-one occurred during intentional use for the child's allergic reaction. Seventeen children experienced lacerations. In 4 cases, the needle stuck in the child's limb. In 1 case, the device lacerated a nurse's finger. The device associated with the injury was operated by health care providers (6 cases), the patient's parent (12 cases, including 2 nurses), educators (3 cases), and the patient (1 case). Of the 3 epinephrine autoinjectors currently available in North America, none include instructions to immobilize the child's leg. Only 1 has a needle that self-retracts; the others have needles that remain in the thigh during the 10 seconds that the user is instructed to hold the device against the leg. Instructions do not caution against reinjection if the needle is dislodged during these 10 seconds. CONCLUSION: Epinephrine autoinjectors are lifesaving devices in the management of anaphylaxis. However, some have caused lacerations and other injuries in children. Minimizing needle injection time, improving device design, and providing instructions to immobilize the leg before use may decrease the risk of these injuries.

Needlestick injuries at a tertiary teaching hospital in Singapore.

This study investigated the incidence and risk to staff groups for sustaining needlestick injuries (NSIs) in the National University Hospital (NUH), Singapore. A retrospective cohort review of incident NSI cases was undertaken to determine the injury rate, causation, and epidemiological profile of such injuries. Analysis of the risk of sustaining recurrent NSI by occupation and location was done using the Cox proportional hazards model. There were 244 NSI cases in 5957 employees in NUH in 2014, giving an incidence rate of 4·1/100 healthcare workers (HCWs) per year. The incidence rate was highest for doctors at 21·3, and 2·7 for nurses; 40·6% of injuries occurred in wards, and 32·8% in operating theatres. There were 27 cases of repeated NSI cases. The estimated cost due to NSIs in NUH ranged from US$ 109 800 to US$ 563 152 in 2014. We conclude that creating a workplace environment where top priority is given to prevention of NSIs in HCWs, is essential to address the high incidence of reported NSIs. The data collected will be of value to inform the design of prevention programmes to reduce further the risk of NSIs in HCWs.

Prevalence of percutaneous injuries and associated factors among health care workers in Hawassa referral and adare District hospitals, Hawassa, Ethiopia, January 2014.

BACKGROUND: Accidental percutaneous injury and acquiring blood-borne diseases are common problems among health care workers (HCWs). However, little is known about the prevalence and associated factors for needle stick injury among HCWs in Ethiopia. METHODS: A cross sectional study was conducted by including 526 HCWs (physicians, nurses, laboratory technicians, midwives and others), working in two public hospitals (Hawassa Referral and Adare District hospitals), from January 1-30, 2014. Binary logistic regression was done to assess the association of selected independent variables with accidental percutaneous injury. RESULTS: The prevalence of at least one episode of percutaneous injury was about 46% of which more than half (28%) occurred within one year prior to the study period and only 24% took prophylaxis for human immune deficiency virus (HIV) infection. The adjusted logistic regression analysis revealed that HCWs who recap needles were twice as likely to face a percutaneous injury. Chance of exposure to needle stick or sharp injuries also increased with increase in educational status. Having a previous history of needle stick or sharp injury was found as one of the risk factors for the occurrence of another injury. Nurses and cleaners were also at increased risk for the occurrence of percutaneous injuries. CONCLUSION: Needle stick and sharp injuries were common among HCWs in the study hospitals, which warrants training on preventive methods.

An Autopsy Checklist: A Monitor of Safety and Risk Management.

Any autopsy has safety and risk management issues, which can arise in the preautopsy, autopsy, and postautopsy phases. The London Health Sciences Department of Pathology and Laboratory Medicine Autopsy Checklist was developed to address these issues. The current study assessed 1 measure of autopsy safety: the effectiveness of the checklist in documenting pathologists' communication of the actual or potential risk of blood-borne infections to support staff. Autopsy checklists for cases done in 2012 and 2013 were reviewed. The frequency of communication, as recorded in checklists, by pathologists to staff of previously diagnosed blood-borne infections (hepatitis B/C and human immunodeficiency virus) or the risk of infection based on lifestyle (eg, intravenous drug abuse) was tabulated. These data were compared with medical histories of the deceased and circumstances of their deaths described in the final autopsy reports. Information about blood-borne infections was recorded less frequently in the checklists compared with the final reports. Of 4 known human immunodeficiency virus cases, there was no checklist documentation in 3. All 11 hand injuries were documented. None of these cases had known infectious risks. The Autopsy Checklist is a standardized means of documenting safety and risk issues arising during the autopsy process, but its effectiveness relies on accurate completion.

Reducing injecting-related injury and diseases in people who inject drugs: Results from a clinician-led brief intervention.

BACKGROUND: The burden of disease associated with injecting-related injury and diseases (IRIDs) is significant among people who inject drugs (PWID). OBJECTIVE: The aim of this study was to evaluate a clinician-led brief intervention involving safer injecting messages and demonstration of safer injecting techniques at the time of venepuncture for serological testing. METHODS: We conducted a before and after evaluation study. History of IRIDs and injecting-related risk behaviours were assessed and compared at baseline and follow-up. RESULTS: Fifty-eight participants completed the pre-intervention and post-intervention evaluation surveys. Compared to baseline, at follow-up fewer participants reported not cleaning their hands prior to injecting (16% cf 31%; P = 0.039); more reported applying a tourniquet correctly (38% cf 24%; P = 0.008), never missing a vein (56% cf 31%; P = 0.007), and applying pressure for at least one to two minutes after injecting (33% cf 13%; P = 0.035). DISCUSSION: The intervention was found to be feasible, justifying its inclusion into routine clinical care. We recommend that other health services targeting PWID implement similar interventions.

Interesting case of a sewing needle inside the heart: report of a case.

Despite being rarely seen, penetrating cardiac injuries are clinically significant, as they are highly lethal. We herein present the case of a 3-year-old male who unintentionally injured himself by pricking his own chest with a sewing needle and introducing it through the left-lower margin of his sternum into his right ventricle. The needle was located anterior-posteriorly over the right ventricle. An anterior thoracotomy was performed, and the needle was safely removed. No hemorrhage or arrhythmia was seen, so the operation was ended. An early diagnosis and intervention proved to be life-saving for this penetrating cardiac injury.

[Investigation of a Novel Intravenous Catheter "Safe Wing Cath"].

BACKGROUND: A Safe Wing Cath (SWC) is a novel intravenous catheter which has a unique needlestick injury safety mechanism. METHODS: We investigated the success rate of intravenous catheterization using SWC by questionnaire. Anesthesiologists were recruited who had no previous experience of using SWC. Two or three consecutive trials were subjected for investigation. RESULTS: During four months in 2012, 8 anesthesiologists were asked to do the job 23 times. The success rate was 62.5% at first use by each anesthesiologist 87.5% at second use, and 100% at third use. CONCLUSIONS: Experienced anesthesiologists can learn the technique of SWC on its second or third use.
