Assessing the Economic Feasibility of Needle-Retractable Safety Syringes (NRSS) Adoption in Indian Healthcare Facilities

Description: Globally, sixteen billion injections are given each year, 95.00% of which are for medicinal purposes. This global injection burden is accounted for by India between 24.5% and 31.0%, and alarmingly, over 62.50% of these injections are performed improperly or are repeated. Objectives: The purpose of this study is to assess the increased costs incurred by transitioning from traditional disposable syringes to Needle-Retractable Safety Syringes (NRSS) for beneficial usage in India. Methods: Utilizing a decision tree model, we evaluated the occurrence of needle-stick injuries and syringe reuse among healthcare personnel and patients. We calculated the lifetime costs associated with HIV - Human Immunodeficiency Virus, HBV - Hepatitis B Virus, and HCV - Hepatitis C Virus infections using three Markov models. Results: NRSS offer substantial benefits by reducing needle-stick injuries and preventing blood-borne infections. Among the options analyzed, Reuse Prevention (RUP) syringes emerged as the most cost-effective choice. In contrast, Single-Use Prevention (SIP) and NRSS syringes are currently not deemed cost-effective at their prevailing prices. We recommend prioritizing RUP syringes and exploring strategies to make them more affordable for broader accessibility. Conclusion: Our analysis suggests that, in the Indian context, RUP syringes present an economically viable solution. However, SIP and NRSS syringes do not currently offer cost-effectiveness. To enhance the cost-effectiveness of NRSS, concerted efforts should be directed towards reducing their price.

Echogenic needles versus non-echogenic needles for in-plane ultrasound-guided infraclavicular axillary vein cannulation, a randomized controlled trial.

Echogenic needles improve the reflection of the ultrasound beam. The aim of the study was to compare needle performance during ultrasound-guided cannulation of the infraclavicular axillary vein with an in-plane needle approach, using echogenic needles or non-echogenic standard needles. One hundred adult patients undergoing surgical procedures that required a central venous catheter were randomized for either echogenic or non-echogenic needles. The primary outcome was access time. Secondary outcomes encompassed total procedure time, success in first attempt, number of attempts, number of skin punctures, change of site for vascular access, catheter placement, subjective experience with needle visualization and needle procedure, and adverse events. Median (IQR) [range] venous access time was 21 (15-56) [6-440] in echogenic needle group and 26 (14-91) [6-925] in the non-echogenic needle group (p = 0.40). No statistically significant differences were found in the secondary outcome measures. One patient (non-echogenic needle group) experienced pneumothorax. In three patients in each group (6%) arterial puncture occurred. Echogenic needles did not significantly improve needle control or safety when used for infraclavicular axillary vein cannulation with an in-plane needle approach. The results indicate that standard needles are appropriate for ultrasound guided subclavian vascular access in a perioperative situation.

Puncture Cube Patient-Mounted Navigation System versus Freehand Method for CT-Guided Needle Placement: Study on a Neoprene Covered Elliptical Cylinder Gelatin Phantom.

The study aims to show how the "Puncture Cube" (PC) (Medical Templates, Egg, Switzerland) compares to the freehand method (FHM) for CT-guided punctures. The PC is a patient-mounted disassemblable cube consisting of an upper and lower template with multiple holes each to predefine puncture trajectory. A total of 80 punctures (FHM in-plane, FHM off-plane, PC in-plane, PC off-plane) was performed by 4 radiologists on a target 9.1cm below surface level of a neoprene covered elliptical cylinder gelatin phantom. The PC was never disassembled. Evaluated parameters were procedure time, number of CT-scans, euclidean distance (ED) and normal distance (ND). Respective parameters of FHM and PC were compared using the Wilcoxon signed-rank test and Levene test with significance levels of 5%. PC achieved smaller ED and ND values after initial needle insertion without corrections for both in-plane and off-plane punctures (P > 0.05). Variance of initial NDs was off-plane significantly larger for FHM. Final ED after needle path corrections was smaller for FHM both in- and off-plane (P < 0.05). Final off-plane ND was significantly lower for FHM with no significant difference in final in-plane ND. FHM off-plane punctures were significantly faster. There was no significant difference in CT-scans between both methods. Utilizing the PC may improve initial needle positioning and safety especially off-plane. However, better final needle positioning after correction with the greater freedom of movement method may suggest need for disassembly of the cube.

Navigating the layers of concern for safe dry needling of the rectus abdominis: a cadaveric study

ABSTRACT Objectives To assess needle placement accuracy in the rectus abdominis (RA) muscle during dry needling (DN) without entering the peritoneum. Methods Two physical therapists performed DN on a cadaver, making 10 attempts each to needle the RA without entering the peritoneum. Techniques followed two common DN approaches. Ultrasound verified needle depth and safety. Results Seventy percent of attempts were recorded as safe needle placement, while 30% were unsafe. Accurate RA needle placement without peritoneal entry occurred in 55% of attempts. Discussion/Conclusion Inadvertent peritoneal needle placement during RA DN poses risks regardless of experience. Ultrasound guidance may enhance safety and precision in clinical practice.

Effectiveness and safety of Buzzy device in needle-related procedures for children under twelve years of age: A systematic review and meta-analysis.

Pain transcends simple physiology, encompassing biological, emotional, psychological, and social facets. Children show pronounced immediate and enduring responses to pain-related procedures. The aim of this meta-analysis is to investigate the efficacy and safety of the Buzzy device for needle-related procedures in children aged twelve years or younger. PubMed, Web of Science, and Embase were searched from inception to July 2023. Only randomized controlled trials utilizing the Buzzy device for needle-related procedures in children under twelve years old were included. Two reviewers independently conducted study selection, data extraction, and risk of bias assessment. Random-effects models were utilized, and analyses were performed using mean differences or standardized mean differences as well as risk ratios. A total of 19 studies were included, involving 2846 participants (Buzzy = 1095, Control = 1751). Compared to no intervention, the Buzzy device significantly reduced pain response [self-report SMD = -1.90 (-2.45, -1.36), parental SMD = -3.04 (-4.09, -1.99), observer SMD = -2.88 (-3.75, -2.02)] and anxiety scores [self-report SMD = -1.97 (-3.05, -0.88), parental SMD = -2.01 (-2.93, -1.08), observer SMD = -1.92 (-2.64, -1.19)]. Compared to virtual reality (VR), the Buzzy device reduced self-reported anxiety levels SMD = -0.47 (-0.77, -0.17), and compared to distraction cards, the Buzzy device reduced parental and observer-reported pain [parental SMD = -0.85 (-1.22, -0.48), observer SMD = -0.70 (-1.00, -0.40)] and anxiety [parental SMD = -0.96 (-1.46, -0.47), observer SMD = -0.91 (-1.40, -0.42)]. Subgroup analysis results showed that procedure type, patient age, measurement scales used, and distance of operation were not the reason of heterogeneity. The summarized first puncture attempt success rate did not differ from other interventions. There were no significant adverse events in the included studies. The Buzzy device reduces pain and anxiety in children during needle procedures, ensuring success and safety. Additionally, the effectiveness of the Buzzy device in reducing pain during venipuncture is superior when compared to its effectiveness during intramuscular injections.

A simple technical innovation to prevent needle stick injuries among dental professionals.

Dental healthcare personnel face the potential danger of being exposed to infectious patients while administering local anesthesia injections during dental operations. This could lead to unintentional transfer of infectious diseases from patients to physicians. Although safety measures such as the One-hand-scoop technique and the use of safety syringes, plastic needle cap holders, and needles with safety caps are in place, there have been instances of needle stick injuries reported in clinics. This might be due to the lack of adherence to conventional safety measures or the impracticality of safety techniques and safety syringes. This article aims to demonstrate the utilization of dental tweezers, specifically London College tweezers or dental forceps, for the secure recapping of needles, eliminating the requirement for extra equipment or devices. After obtaining ethical approval (Approval No.: 024-01-2024) from the College of Dentistry, Dar Al Uloom University, 67 dental professionals, with consent for participation in the study, were included. They were requested to use dental tweezers/London College tweezers and dental extraction forceps such as maxillary anterior, mandibular anterior, and maxillary bayonet root forceps individually to recap the local anesthetic needles. The efficacy of these techniques was evaluated against the one-hand scoop technique for its ease, convenience, and reliability in preventing needle stick injuries. The evaluation of dental professionals regarding the ease of using dental tweezers to recap needles, compared to the one-hand scoop technique (p=0.592), maxillary bayonet root forceps (p=0.746), mandibular anterior forceps (p=0.380), and maxillary anterior forceps (p=0.808), did not yield statistically significant results. The assessment of the procedural simplicity of the one-hand scoop technique showed a satisfaction rate of over 40%, whereas the application of dental tweezers resulted in a satisfaction rate of 30%. However, the use of dental tweezers for needle recapping resulted in a satisfaction rate of over 50%, compared to a satisfaction rate of 30% for the one-handed scoop technique. There is no statistically significant difference in the assessment of the efficacy of dental tweezers and the one-hand scoop technique, bayonet root forceps, mandibular anterior forceps, maxillary anterior forceps, and dental tweezers for the needle capping technique. Therefore, dental forceps can be used instead of the one-handed scoop approach. The needle recapping procedure outlined in our study, aimed at preventing needle stick injuries, is simple to implement, and all dental specialties have convenient access to the required instruments.

Bioequivalence Between a New Omalizumab Prefilled Syringe With an Autoinjector or with a Needle Safety Device Compared with the Current Prefilled Syringe: A Randomized Controlled Trial in Healthy Volunteers.

Omalizumab is an anti-IgE monoclonal antibody currently approved for the treatment of asthma, nasal polyps/chronic rhinosinusitis with nasal polyps, and chronic spontaneous urticaria. Omalizumab is available as an injection in a prefilled syringe (PFS) with a needle safety device (NSD). New product configurations were developed to reduce the number of injections per dose administration, improve patient convenience and treatment compliance. The objective of this randomized open-label 12-week study was to demonstrate pharmacokinetic bioequivalence between (1) new PFS with autoinjector (PFS-AI), (2) new PFS-NSD configuration, and (3) current PFS-NSD configuration. Each new configuration was considered bioequivalent to the current configuration if the confidence intervals (CIs) for the geometric mean ratios (GMR) were contained in the 0.80-1.25 range for maximum concentration (Cmax), area under the concentration-time curve until the last quantifiable measurement (AUClast), and AUC extrapolated to infinity (AUCinf). Safety was assessed throughout the study. In total, 193 healthy volunteers were randomized at 1:1:1 ratio to omalizumab 1×300mg/2mL via new PFS-AI (n = 66), omalizumab 1×300mg/2mL via new PFS-NSD (n = 64), or omalizumab 2×150mg/1mL via current PFS-NSD (n = 63). Comparing new PFS-AI versus current PFS-NSD, the GMRs were: Cmax, 1.085; AUClast, 1.093; AUCinf, 1.100. Comparing new PFS-NSD versus current PFS-NSD, the GMRs were: Cmax, 1.006; AUClast, 1.016; AUCinf, 1.027. The 95% CIs for all GMR parameters were contained within the 0.80-1.25 range. Safety findings were consistent with the known safety profile of omalizumab. Single-dose omalizumab administered as the new PFS-AI or new PFS-NSD was bioequivalent to the current PFS-NSD.

Study of Tissue Damage Induced by Insertion of Composite-Coated Needle

Medical interventions have significantly progressed in developing minimally invasive techniques like percutaneous procedures. These procedures include biopsy and internal radiation therapy, where a needle or needle-like medical device is inserted through the skin to access a target inside the body. Ensuring accurate needle insertion and minimizing tissue-damage or cracks are critical in these procedures. This research aims to examine the coated needle effect on the force required to insert the needle (i.e., insertion force) and on tissue-damage during needle insertion into the bovine kidney. Reducing the needle insertion force, which is influenced by needle surface friction, generally results in a reduction in tissue-damage. Surgical needles were coated with a composite material, combining Polytetrafluoroethylene, Polydopamine, and Activated Carbon. Force measurement during needle insertion and a histological study to determine tissue-damage were conducted to evaluate the effectiveness of the coating. The insertion force was reduced by 49 % in the case of the coated needles. Furthermore, a histological analysis comparing tissue-damage resulting from coated and uncoated needles revealed an average 39 % reduction in tissue-damage with the use of coated needles. The results of this study demonstrate the potential of coated needles to enhance needle insertion and safety during percutaneous procedures.

Investigation of Needle Characteristics Using an Animal Model for Improved Outcomes in Anterior Chamber Paracentesis.

Background/Aims: The current standard of care to perform an anterior chamber paracentesis involves the use of a multipurpose market needle and syringe. The use of standard needles for this purpose may result in injury to the patient due to increased force with insertion and increased globe displacement during the procedure. This research investigates the current market needle characteristics and the impact of each needle characteristic on force. Methods: Several comparative trials were conducted to evaluate the needles. Needle characteristics of interest were gauge, primary bevel angle, number of bevels in the lancet, and needle hub geometry. Measurements of corneal insertion forces were made using a synthetic thermoplastic polyurethane medium, and bovine and porcine models. Needle safety was investigated with corneal abrasion experiments. Results: Reduced insertion force was observed with lower lancet primary angle. There was no difference based on the number of bevels in the lancet. Rounded hub geometry had minimal distribution to the corneal epithelium. Conclusions: Needle characteristics impact the force needed for needle insertion into the tissue. Since higher force can lead to increased risk and less efficiency during the procedure, reducing this force may improve the outcomes of the procedure. Needle entry can be reduced by designing an improved needle that includes a lower gauge and reduced primary angle of the lancet.

Safe and Effective Subcutaneous Self-Injection of Bimekizumab with Safety Syringe and Auto-Injector Devices: Results from a Multicenter, Randomized, Open-Label Study in Patients with Psoriatic Arthritis.

Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A, key drivers of chronic inflammation. Bimekizumab must be injected subcutaneously and so patients require self-injection options that meet their preferences. This study evaluated safe and effective self-injection of bimekizumab by patients with psoriatic arthritis using the 1 mL safety syringe (SSy) or the 1 mL auto-injector (AI). The DV0004 devices study (NCT04109976) was a sub-study of BE VITAL, a multicenter, open-label extension of BE OPTIMAL (NCT03895203) and BE COMPLETE (NCT03896581) in patients with active psoriatic arthritis. After receiving training, patients subcutaneously self-injected bimekizumab 160 mg at Baseline and Week 4. The primary and secondary endpoints were the proportion of patients self-injecting bimekizumab safely and effectively at Week 4 and Baseline, respectively. Patient self-injection experience was evaluated using the pain visual analog scale (VAS) and the Self-Injection Assessment Questionnaire (SIAQ). Overall, 214 patients were randomized 1:1 at Baseline. All evaluable patients safely and effectively self-injected bimekizumab at Week 4 (SSy: n=105; AI: n=104) and Baseline (SSy: n=106; AI: n=106). Mean pain VAS scores were generally low at Week 4 (SSy: 11.0; AI: 11.4) and Baseline (SSy: 9.5; AI: 14.9). High mean pre- and post-injection SIAQ scores (≥6.7) were observed for both devices indicating a positive overall patient experience with self-injection. Self-injection was well tolerated with no reports of treatment-emergent adverse device effects (TEADEs), serious TEADEs or discontinuations due to TEADEs. Four non-device-related injection site reactions during the sub-study were reported in the parent study; all were mild, did not lead to discontinuation and resolved without treatment. All devices maintained their structural and functional integrity post-use. All patients self-injected subcutaneous bimekizumab safely and effectively using either device at Baseline and Week 4. Overall, patients reported a positive self-injection experience.

Ultrasound image guided injection of botulinum toxin for the management of spasticity: A Delphi study to develop recommendations for a scope of practice, competency, and governance framework

ObjectiveTo establish a scope of practice, competency (through education) and governance framework for ultrasound image guided injection of botulinum toxin in the management of spasticity DesignDelphi study SettingInternational, web-based survey ParticipantsA purposively selected multidisciplinary (physicians, physiotherapists, occupational therapists) panel of experts (n=15) in the use of ultrasound image guided injection of botulinum toxin for management of spasticity. Panel members were predominantly based in the UK (11/15). InterventionsIn round 1, open-ended questions were posed relating to potential scope of practice for ‘ultrasound imaging in spasticity management’; (specifically relating to ultrasound image guided injection of Botulinum Toxin) education/competency and governance considerations. In round 2, respondents were asked to rate their level of agreement with the statements generated. Outcome measures5-point Likert scale used for rating the statements. Threshold for consensus agreement was set at 70% or above. ResultsThree different scopes of practice relating to ultrasound imaging in spasticity management were accepted. The primary scope of practice was the use of ultrasound imaging to guide safe and accurate delivery of botulinum toxin. Relating to this primary scope, 7 competency requirements were agreed relating to areas including image optimization and interpretation, needle visualization and safety. A singular, broad governance statement was generated. ConclusionRelating specifically to guided injection of botulinum toxin for management of spasticity, we present a scope of practice, competency, and governance framework. These are integrated within a framework approach to provide a mechanism for increased patient access to accurate, safe, and effective focal spasticity treatment. The framework supports focused training routes, greater inter-profession communication and wider clinical community engagement in spasticity management using this modality.

Safe and effective use of a passive safety needle by healthcare professionals in a simulated environment, including perceptions and preferences

ABSTRACT Background Needlestick injuries (NSIs) may potentially expose healthcare professionals (HCPs) to bloodborne pathogens. Safety needles are designed to protect against NSIs. We evaluated whether a new fully passive safety needle could be used safely by HCPs. Research design and methods The passive safety needle was tested by physicians, nurses, and pharmacists in subcutaneous or intramuscular injection scenarios in simulation studies (1–3). Data collected included successes, close calls, difficulties, use errors, and failures. In study 4, HCPs rated the device safety (21-item questionnaire). Results Overall, 104 participants completed 4772 simulated tasks, including 932 injections. 915 injections (98.18%) were performed successfully and no NSIs (0%) were observed in any of the studies. Studies 1 & 2: 84.15% tasks and 96.06% injections were completed successfully, but use errors occurred, mostly arising from the participants’ mental model. There were no failures in Study 3. In Study 4, >98% of participants responded positively to every question, while all felt that the passive safety feature could eliminate NSIs and would better protect against bloodborne pathogens than other existing devices with active or semi-passive safety mechanisms. Conclusions The passive safety needle was used successfully by HCPs, did not lead to any NSIs, and was rated as the safest compared to similar devices.

Sharps injuries with Lovenox and generic enoxaparin prefilled safety syringes

Investigate the incidence and mechanisms of sharps injuries (SI) to staff using Lovenox and generic enoxaparin prefilled syringes. Four national adverse event databases were examined over a 12-year period for incidence and brands involved with injury events to staff using enoxaparin prefilled syringes. The search revealed 581 adverse events (including 20 sharps injuries) associated with device malfunction in 8 of 16 brands, with one brand mentioned significantly more frequently than others. No national alert had been issued. Use of certain brands of enoxaparin prefilled syringes poses a small but serious risk of injury to staff. Conducting root cause analyses on all SI is essential, as is the need for regularly evaluating safer devices, reporting all device incidents, enabling simpler reporting of adverse events, and establishing more effective intervention by FDA and manufacturers.

Emergency provider preference for powered intraosseous devices and satisfaction with features improving safety, reliability, and ease-of-use

ABSTRACT Background Powered intraosseous (IO) systems are valuable devices for emergent situations, with limited data on user preferences. A simulation/survey-based study was conducted among emergency medical service (EMS) providers to evaluate attitudes toward general powered IO system features to measure preferences/satisfaction for the most-commonly used and a novel powered IO system (with a passive safety needle, battery life indicator, and snap-securement/dressing). Research Design and Methods Forty-two EMS providers completed a simulated activity using both powered IO systems and a 30-item questionnaire, including multiple choice, free-text, ranking, and Likert-like questions. Ranking scores were reported using a scale of 0 (least important/satisfactory) to 100 (most important/satisfactory). Statistical significances were evaluated via Wilcoxon signed-rank sum test. Results Providers indicated driver performance (mean score ± SD; 77.8 ± 27.5) and IO needle safety mechanism (63.1 ± 27.9) as the most important features. Participants reported significantly higher (p < 0.001) satisfaction with the novel IO system overall, and its needle safety, battery life indicator, securement/dressing, and ease-of-use. Powered driver performance satisfaction was similar and favorable for the novel (88.1 ± 18.2) and traditional (87.1 ± 15.3) systems. Conclusions These findings highlight the value of clinician/user input and demonstrate EMS providers are more satisfied with a powered IO system featuring design elements intended to enhance safety and ease-of-use.

Occupational exposure to blood and body fluids among prehospital emergency medical services workers in Mashhad, Northeast of Iran

This study aimed to assess occupational exposure to blood and body fluids (BBFs) and the use of protective equipment among prehospital emergency medical services (EMS) workers in Mashhad, Iran. This cross-sectional questionnaire survey-based study was conducted from July 2020 to March 2021 in Mashhad. All prehospital EMS workers of Mashhad were invited to participate in the study using the census technique. The questionnaire was about occupational exposure to BBFs, infection control, protective measures, health program, and demographic information. In total, 442 participants answered the questionnaire (response rate: 82.77%). Based on the findings, 420 (95.2%) and 402 (91.2%) participants had been exposed to BBFs as prehospital EMS workers. Moreover, 31.5% and 38.5% of these exposures were caused by contaminated needles and lancets, respectively. The BBFs incidents have occurred despite 98% of the EMS workers reporting there is a needle safety disposable box in the ambulance. The relationship between awareness of precaution measures after exposure to BBFs and training course completion was significant (P < .0001). This study demonstrated the high prevalence of occupational exposures to BBFs among prehospital EMS workers. Considering the significant relationship between the completion of standard precautions courses and awareness of BBFs' postexposure measures, it is recommended to consider multi-faceted strategies for continuous monitoring, training, and follow-up of prehospital EMS workers.

Patterns of Occupational Exposure to Human Immunodeficiency Virus and Post-Exposure Prophylaxis Among Health Care Personnel in a Tertiary Care Institute in South India - A Retrospective Case Series.

Post-exposure prophylaxis (PEP) for occupational human immunodeficiency virus (HIV) exposure involves the comprehensive measures used to prevent transmission of blood-borne pathogens such as HIV, hepatitis B virus, and hepatitis C virus through various strategies such as first aid, counseling, risk assessment, relevant laboratory investigations with informed consent, the provision of short-term anti-retroviral drugs, and follow-up testing. We sought to investigate the patterns and causes of occupational exposure in health care workers (HCWs) in our institute and the usage of PEP in our center, a tertiary care hospital in south India. The study involved a retrospective analysis of data extracted from the records of PEP usage from the anti-retroviral treatment (ART) center attached to the dermatology, venereology and leprosy out-patient department of a tertiary care center in south India. The data were extracted into a pre-designed proforma and analyzed using descriptive statistics. A total of 352 health care professionals reported to the ART center for PEP from 2010 to 2020. One hundred and thirty-four patients took only the first dose as the source patient later tested to be HIV-negative. Among the 218 remaining patients, 84 were male and 134 were female patients. Only 56 health care workers started the regimen within 2 hours. One hundred and thirty-four patients completed the full course of PEP. Most HCWs (n = 68, 31%) sustained the exposure while doing a procedure on the patient followed by re-capping a needle (n = 64, 29%). Gastritis and drowsiness were the most common adverse effects. The study was limited by the retrospective nature of data collection and the lack of detailed interviews with HCWs. Knowledge about PEP, needle safety training, and training of early first aid measures should be increased among health care workers.

Non-Safety and Safety Device Sharp Injuries-Risk of Incidents, SEDs Availability, Attitudes and Perceptions of Nurses According to Cross-Sectional Survey in Poland.

Sharp injuries are a serious issue among healthcare workers (HCWs). The aim of the study was to examine the frequency of sharps injuries among nurses (who have the most frequent contact with infectious material) when using devices with and without safety features, then to analyse the factors associated with such injuries and to compare the risk of injuries with safety engineered devices (SEDs) and non-safety engineered devices (non-SEDs). An online cross-sectional survey was completed between October 2021 and March 2022 by 280 nurses. The incidence of exposure to sharp injury during their professional life was 51.4%. The percentage of nurses experiencing a sharp injury in the year preceding the study was 29% and 9.6% for superficially and deep injury, respectively. Ampoules and conventional hollow-bore needles caused the most injuries (25.92% and 22.64% of nurses in the last year). Factors including sex (males), age and seniority (elderly), education (higher), work exhaustion and being left-handed were associated with the occurrence of conventional hollow-bore needle injuries. In the case of SEDs: age, seniority and right/left-handed were the most frequent risk factors associated with the occurrence of sharp injuries. SEDs injuries were much less frequent than non-SEDs. There was a significant difference between the risk of injuries with safety and non-safety needles, central cannulas and ampoules. Fisher’s exact test (p-value = 0.000) and positive Spearman’s rho statistics (0.2319, p-value = 0.0001) confirmed that in accredited hospitals, the availability of safety needles was higher. Almost half of the nurses (n = 115, 41.07%) stated that staff had little influence on the type of medical sharp instruments supplied. To reduce the risk of nurse injuries, access to medical devices with safe protection mechanisms should be ensured, the use of sharp instruments should be limited where possible, managers should consult nurses regarding the choice of safe devices, and training programs on the proper use of SEDs should be available.
