Saving time when preparing intravenous antibiotics.

Preparation of intravenous antibiotic doses takes up a significant amount of nurse time and exposes nurses to the risk of needlestick injury. The use of the Ecoflac® Connect needle-free connector could streamline preparation, reducing the time taken as well as eliminating needlestick injury risk. Because Ecoflac Connect is a closed system, it also minimises the risk of microbial contamination. This study showed that it took 83 experienced nurses 73.6 (SD 25.0) seconds to prepare an amoxicillin injection using the Ecoflac Connect needle-free connector compared with 110.0 (SD 34.6) seconds using the standard needle and syringe method, saving 36 seconds per dose on average, reducing the time taken by one-third. Based on recent government figures, the saving in nurse time would equate to 200-300 full-time nurses in England, equivalent to £6.15 million-£9.23 million a year. Additional savings would accrue from the prevention of needlestick injuries. Where wards are understaffed, this time saving could be critical, increasing time for care.

Differences in the incidence of aflibercept-related sterile endophthalmitis according to types of disposable syringes used.

PURPOSE: To evaluate the difference between the incidences of sterile endophthalmitis after administration of intravitreal aflibercept injection using two different types of syringes. METHODS: We administered a total of 498 intravitreal aflibercept injections between September 2017 and August 2021. The disposable syringe used was changed from a 1-mL disposable syringe (Profi syringe, Shinchang Medical., Ltd. Korea) to a 1-mL Becton Dickenson Luer-Lok syringe (BD, Franklin, NJ, USA) in September 2019. Thus, the patients who received injections before and after September 1, 2019, were classified into group 1 and group 2, respectively. The incidence of aflibercept-related sterile endophthalmitis between the two groups was compared. RESULTS: In group 1, six (2.791%) out of 215 cases were diagnosed with sterile endophthalmitis and prescribed topical or oral steroids. In group 2, one (0.353%) out of 283 cases was diagnosed with sterile endophthalmitis and prescribed a steroid eye drop. The incidence of sterile endophthalmitis was significantly different between the two groups (P = 0.046). CONCLUSION: The BD Luer-Lok syringe is associated with a lower incidence of aflibercept-related sterile endophthalmitis than the conventional polypropylene syringe. Differences in immunogenicity associated with silicone oil lubricants within the syringes might be one of the potential reasons behind the difference in the incidence of the sterile endophthalmitis.

Have Legislative Interventions Impacted the Incidence of Needlestick Injuries?

Introduction The aim of this study was to examine the impact the EU Directive for the Prevention of Sharps injuries had on the incidence of needlestick injuries (NSI) in Ireland. Methods A five-year retrospective study prior to, and after the introduction of these regulations, was conducted. Secondary data from the Occupational Health Department's annual NSI reports were used. The population studied were healthcare workers who reported a NSI from 2013 to 2017. Results The incidence of NSI varied from 157 in 2017 to 207 in 2014. 'Miscellaneous needles' was the category which caused the most NSI (23%). 'Disposable needles with syringes' accounted for 20% of all NSI before the legislation; this figure was reduced to 12-15% after the regulations were introduced. Conclusion The EU regulations did not reduce the incidence of NSI. A lower incidence of NSI was reported from 'disposable needles with syringes' after the implementation of the regulations.

Investigating Serious Adverse Drug Reactions in Patients Receiving Erythropoiesis-Stimulating Agents: A Root Cause Analysis Using the "ANTICIPATE" Framework.

BACKGROUND: Unexpected serious adverse drug reactions (sADRs) affecting patients with chronic kidney disease (CKD) who received erythropoiesis-stimulating agents were identified by study co-authors. These included pure red cell aplasia (PRCA) after administration of the Eprex formulation of epoetin or the epoetin biosimilar HX575 and fatal anaphylaxis associated with peginesatide, an erythropoietin receptor agonist. We developed and applied a structured framework to describe these sADRs, including root cause analyses and eradication efforts. METHODS: A 10-step framework termed "ANTICIPATE," focusing on signal identification, incidence, causality, and eradication guided our evaluations. RESULTS: Initial cases were identified by a hematologist (Eprex), clinical study monitors (HX575), and 4 nurses (peginesatide). The number of persons with individual ADRs was 13 PRCA cases for epoetin, 2 antibody-mediated PRCA cases for HX575, and 5 fatal anaphylaxis cases for peginesatide. Initial incidence estimates per 1000 treated persons were 0.27 for Eprex-associated PRCA, 11 for HX575-associated PRCA, and 0.38 for peginesatide fatalities. Likely causes were subcutaneous administration of epoetin formulated with polysorbate 80 (Eprex), tungsten leaching from pins included in product syringes (HX575), and inclusion of a phenol stabilizer (peginesatide). Eradication strategies included restricting Eprex administration to the intravenous route, excluding tungsten from HX575 syringes, and for peginesatide, proposed eradication was to return to single-dose vials without preservatives. CONCLUSION: Although the number of cases of each sADR was small, eradication was successful for 2 sADRs, and a proposed eradication was developed for a third sADR. The structured framework used to describe the above 3 sADRs in patients with CKD can also be used in other clinical settings.

Expediting red blood cell transfusions by syringing causes significant hemolysis.

BACKGROUND: Techniques commonly used to expedite blood transfusions include pneumatically pressurizing red blood cell (RBC) bags or manual syringing its contents. We compared these techniques on RBC hemolysis using a simulated transfusion model. STUDY DESIGN AND METHODS: Fifteen warmed RBC units that were 12.3 ± 4.3 (95% confidence interval [CI], 10.1-14.5) days old were each subjected to two experimental rapid transfusion techniques. RBCs from each technique were directed through 18- and 22-gauge cannulas attached to blood administration sets. One technique involved RBC bag pressurization to 300 mmHg. The other employed a 20-mL syringe to effect forceful, manual aspiration from the RBC bag followed by forceful, manual RBC injection. The control group was gravity driven without cannulas. Free hemoglobin (Hb) concentrations were measured and percent hemolysis was calculated. RESULTS: Free Hb concentrations and percent hemolysis (median [95% CI]) were similar in the control (0.05 [0.03-0.08] g/dL and 0.13% [0.09%-0.17%], respectively) and pressurized experiments (0.06 [0.05-0.09] g/dL; 0.14% [0.12%-0.22%]), respectively. Syringing resulted in 10-fold higher free Hb concentrations (0.55 [0.38-0.92] g/dL) and percent hemolysis (1.28% [1.03%-2.15%]) than when employing the control (p < 0.0001) or pressurization (p < 0.0001) techniques. Cannula sizes studied did not affect hemolysis. CONCLUSION: Forceful manual syringing caused significant hemolysis and high free Hb concentrations. Pressurizing RBC bags induced no more hemolysis than after gravity-facilitated transfusions. Syringing to expedite RBC transfusions should be avoided in favor of pneumatic RBC bag pressurization.

Injection practice in Kaski district, Western Nepal: a community perspective.

BACKGROUND: Previous studies have shown that unsafe injection practice is a major public health problem in Nepal but did not quantify the problem. The present community-based study was planned to: 1) quantify injection usage, 2) identify injection providers, 3) explore differences, if any, in injection usage and injection providers, and 4) study and compare people's knowledge and perception about injections between the urban and rural areas of Kaski district. METHODS: A descriptive, cross-sectional mixed-methods study was conducted from July to November 2012, using a questionnaire based survey and focus group discussions (FGDs). A semi-structured questionnaire advocated by the World Health Organization was modified and administered to household heads and injection receivers in selected households and the FGDs were conducted using a topic guide. The district was divided into urban and rural areas and 300 households from each area were selected. Twenty FGDs were held. RESULTS: In 218 households (36.33%) [99 in urban and 119 in rural] one or more members received at least one injection. During the three month recall period, 258 subjects (10.44%) reported receiving injection(s) with a median of two injections. The average number of injections per person per year was calculated to be 2.37. Health care workers (34.8%), staff of medical dispensaries (37.7%), physicians (25.2%), and traditional healers (2.3%) were consulted by the respondents for their basic health care needs and for injections. Compared to urban respondents, more rural respondents preferred injections for fever (p < 0.001). People preferred injections due to injections being perceived by them as being powerful, fast-acting, and longer lasting than oral pills. More than 82% of respondents were aware of, and named, at least one disease transmitted by using unsterile syringes during injection administration or when syringes are shared between people. CONCLUSIONS: Less preference for injections and high awareness about the association between injections and injection-borne infections among the general population is encouraging for safe injection practice. However, respondents were not aware of the importance of having qualified injection providers for safe injections and were receiving injections from unqualified personnel.

A randomised controlled trial using the Epidrum for labour epidurals.

The aim of our study was to determine if using the Epidrum to site epidurals improves success and reduces morbidity. Three hundred parturients requesting epidural analgesia for labour were enrolled. 150 subjects had their epidural sited using Epidrum and 150 using standard technique. We recorded subject demographics, operator experience, number of attempts, Accidental Dural Puncture rate, rate of failure to site epidural catheter, rate of failure of analgesia, Post Dural Puncture Headache and Epidural Blood Patch rates. Failure rate in Epidrum group was 9/150 (6%) vs 0 (0%) in the Control group (P = 0.003). There were four (2.66%) accidental dural punctures in the Epidrum group and none in the Control group (P = 0.060), and 2 epidurals out of 150 (1.33%) in Epidrum group were re-sited, versus 3/150 (2%) in the control group (P = 1.000). The results of our study do not suggest that using Epidrum improves success or reduces morbidity.

Comparison of injection pain caused by the DentalVibe Injection System versus a traditional syringe for inferior alveolar nerve block anaesthesia in paediatric patients.

AIM: To compare paediatric patients' pain during needle insertion and injection in inferior alveoler nerve block (IANB) anaesthesia injected by either a traditional syringe (TS) or the DentalVibe Injection Comfort System (DV). STUDY DESIGN: the study was a randomised controlled crossover clinical trial, comprised of 60 children aged 6-12 requiring an operative procedure with IANB anaesthesia on their mandibular molars bilaterally. One of the molar teeth was treated with TS and the contralateral tooth was treated with DV. On each visit, subjective and objective pain was evaluated using the Wond-Baker Faces Pain Rating Scale (PRS) and the Face, Legg, Cry, Consolability Scale (FLACC Scale). Patients were asked which anaesthesia technique they preferred. Data were analysed using Wilcoxon signed rank, Spearman correlation, and Mann-Whitney U tests. RESULTS: There were no statistically significant differences for pain evalution during needle insertion and injection of each injection system. However, a negative correlation was found on the FLACC between age and pain scores during injection after using DV. CONCLUSION: Paediatric patients experienced similar pain during IANB anaesthesia administered with TS and DV. With increased age, pain values reduced during anaesthetic agent injection with DV according to FLACC. The traditional procedure was preferred to DV in paediatric patients.

Assessment of the risk of needlestick injuries associated with intravitreal injections.

PURPOSE: To assess the overall risk of needlestick injuries (NSIs) associated with intravitreal injection, and more specifically related to the practice of compounding pharmacies of applying informational adhesive stickers to repackaged bevacizumab injection syringes. METHODS: This cross-sectional study involved an online survey of retina specialists in the United States. RESULTS: Of the 717 invited retina specialists, 158 (22%) responded to the online survey. The respondents reported using 1 pair of gloves (51%), no gloves (46%), or 2 pairs of gloves (3%) during intravitreal injection. Repackaged bevacizumab syringes distributed by compounding pharmacy were used by 89% of the respondents, and 63% reported that the adhesive sticker was applied directly to the syringe. Unintentional adhesion between the sticker and hand or glove was experienced by 9% of respondents. At least 1 NSI during intravitreal injection was experienced by 8% of respondents, and sticker-related injury was reported by 3%. The sticker was perceived to increase risk for NSI by 33% of respondents. CONCLUSION: This survey showed that 8% of the responding physicians surveyed have experienced at least one NSI during intravitreal injections, of which approximately one third was attributed to the adhesive sticker. Direct application of misfitting stickers to repackaged syringes by compounding pharmacies may be a practice that can aggravate the risk of NSI.

[Check valves : Important facts for safe use]. / Rückschlagventile : Wissenswerte Eigenschaften für die sichere Anwendung.

Patients benefit from the use of check valves when drugs with a particularly short half-life (e.g., catecholamines) are continually administered through a one-way valve or when an accidental retrograde bolus application must be prevented, as in the event of a rapid sequence induction and intubation. The lack of a check valve can prevent the administered drug from working in the intended manner resulting in potentially insufficient treatment and negative consequences for the patient. In order to ensure the highest level of patient safety while using check valves appropriate training of medical personnel is essential. In contrast, preventable dangers (e.g., infections, awareness) exist when safety measures are disregarded, including the re-use of medications, syringes or disposable materials in successive patients after having only exchanged the check valves. It is not clear how often this is practiced in German-speaking areas.

Incarceration is associated with used syringe lending among active injection drug users with detectable plasma HIV-1 RNA: a longitudinal analysis.

BACKGROUND: Informed by recent studies demonstrating the central role of plasma HIV-1 RNA viral load (VL) on HIV transmission, interventions to employ HIV antiretroviral treatment as prevention (TasP) are underway. To optimize these efforts, evidence is needed to identify factors associated with both non-suppressed VL and HIV risk behaviours. Thus, we sought to assess the possible role played by exposure to correctional facilities on VL non-suppression and used syringe lending among HIV-seropositive people who use injection drugs (PWID). METHODS: We used data from the ACCESS study, a community-recruited prospective cohort. We used longitudinal multivariate mixed-effects analyses to estimate the relationship between incarceration and plasma HIV-1 RNA > 500 copies/mL among antiretroviral therapy (ART)-exposed active PWID and, during periods of non-suppression, the relationship between incarceration and used syringe lending. RESULTS: Between May 1996 and March 2012, 657 ART-exposed PWID were recruited. Incarceration was independently associated with higher odds of VL non-suppression (Adjusted Odds Ratio [AOR] = 1.54, 95% Confidence Interval [95% CI]: 1.10, 2.16). In a separate multivariate model restricted to periods of VL non-suppression, incarceration was independently associated with lending used syringes (AOR = 1.81, 95% CI: 1.03, 3.18). CONCLUSIONS: The current findings demonstrate that incarceration is associated with used syringe lending among active PWID with detectable plasma HIV-1 RNA. Our results provide a possible pathway for the commonly observed association between incarceration and increased risk of HIV transmission. Our results suggest that alternatives to incarceration of non-violent PWID and evidence-based combination HIV prevention interventions for PWID within correctional facilities are urgently needed.

Patient notification for bloodborne pathogen testing due to unsafe injection practices in the US health care settings, 2001-2011.

BACKGROUND: Syringe reuse and other unsafe injection practices can expose patients to bloodborne pathogens (eg, hepatitis B and C viruses and human immunodeficiency virus). Evidence of such infection control lapses has resulted in patient notifications, but the scope and magnitude of these events have not been well characterized. OBJECTIVES: To summarize patient notification events resulting from unsafe injection practices in the US health care settings. METHODS: We examined records of events that involved communications to groups of patients, conducted during 2001-2011, advising bloodborne pathogen testing stemming from potential exposures to unsafe injection practices. RESULTS: We identified 35 patient notification events related to unsafe injection practices in at least 17 states, resulting in an estimated total of 130,198 patients notified. Among the identified notification events, 83% involved outpatient settings and 74% occurred since 2007, including the 4 largest events (>5000 patients per event). The primary breach identified (≥16 events; 44%) was syringe reuse to access shared medications (eg, single-dose or multidose vials). Twenty-two (63%) notifications stemmed from the identification of viral hepatitis transmission, whereas 13 (37%) were prompted by the discovery of unsafe injection practices, absent evidence of bloodborne pathogen transmission. CONCLUSIONS: Unsafe injection practices represent a form of medical error that have manifested as large-scale adverse events, affecting thousands of patients in a wide variety of health care settings. Our findings suggest that increased oversight and attention to basic infection control are needed to maintain patient safety, along with research to identify best practices for triggering and managing patient notifications.

A clinical evaluation of four non-Luer spinal needle and syringe systems.

We performed an evaluation of non-Luer spinal devices supplied by four manufacturers or suppliers: Polymedic; Pajunk; Sarstedt; and Smiths. For each supplier, 100 evaluations were performed using a 25-G 90-mm spinal needle, 3-ml syringe, 5-ml syringe and filter needle; for comparison, 100 evaluations were performed with our standard Luer equipment. The non-Luer devices were associated with more qualitative problems compared with the Luer devices, for example, poor feel of dural puncture (9-32% vs 10%, respectively), poor observation of cerebrospinal fluid in the hub (3-27% vs 0%), and connection problem of the syringe to the spinal needle (7-33% vs 0%). There was also more frequent failure to achieve the spinal injection due to equipment-related causes (4-7% vs 0%, respectively). Median (IQR [range]) numeric satisfaction scores for the spinal needles were: Luer 10 (9-10 [7-10]); Polymedic 7 (4-8 [0-10]; Pajunk 7 (5-8 [0-10]); Sarstedt 7 (6-8 [0-10]); and Smiths 9 (7-10 [0-10]) (p<0.0001). Satisfaction scores for all spinal equipment were: Luer 10 (9-10 [5-10]); Polymedic 8 (6-8 [0-10]); Pajunk 7 (5-7 [1-9]); Sarstedt 8 (6-8 [0-10]); and Smiths 8 (8-9 [2-10]) (p<0.0001). Between 21% and 75% of non-Luer evaluations were rated with satisfaction worse than the usual Luer needle compared with 0-10% rated better, depending on the needle type. Between 22% and 76% of non-Luer evaluations were rated with satisfaction worse than the usual Luer equipment compared with 0-14% rated better. Specific concerns included poor feel of tissue planes and observation of cerebrospinal fluid (Polymedic), difficulty with connection of the syringe to the spinal needle and trocar removal (Pajunk), poor feel of tissue planes and needle flexibility (Sarstedt) and difficulty with connection of the syringe to the spinal needle (Smiths). We could not demonstrate a short-term learning curve for the new devices. Decisions on purchasing and implementation of the new non-Luer equipment will have to acknowledge that clinicians may have greater technical problems and reduced satisfaction compared with the current equipment.

Measles supplementary immunization activities and GAVI funds as catalysts for improving injection safety in Africa.

BACKGROUND: In 2000, reuse of disposable syringes and inadequately sterilized syringes resulted in 39% of all injections being unsafe, causing 22 million infections. We describe the contribution of measles supplemental immunization activities (SIAs) and Global Alliance for Vaccines and Immunisation (GAVI) funding in replacing disposable and sterilizable syringes with auto-disable (AD) syringes to improve injection safety in 39 African countries. METHODS: We assessed trends in nationwide introduction of AD syringes against measles catch-up SIAs and GAVI funding using World Health Organization/United Nations Children's Fund (UNICEF) Joint Reporting Form for Immunization and UNICEF supply data. RESULTS: In 19 (49%) of 39 countries, the measles program catalyzed the introduction of injection safety equipment, including AD syringes and safety boxes, training, and procurement of safety equipment during SIAs. GAVI was catalytic through financial support in 14 countries (36%) for including safe injection equipment in routine immunization. Additionally, GAVI funded 21 countries that had already introduced AD syringes in their national program. UNICEF AD syringe shipments to sub-Saharan Africa increased from 11 million to 461 million from 1997 to 2008. All 39 countries stopped using sterilizable syringes by 2004. CONCLUSIONS: The measles mortality reduction program and GAVI complemented each other in improving injection safety. All countries continued with AD syringes for immunization after measles catch-up SIAs and GAVI funding ended.

[Nosocomial transmission of hepatitis C associated with anesthesia procedures: a case-control study]. / Transmisión nosocomial de la hepatitis C asociada a procedimientos anestésicos: un estudio de casos y controles.

OBJECTIVE: Nosocomial transmission of hepatitis C virus (HCV) infection had been related with anesthesia procedures. The study aim was to measure the association between anesthesia procedures in cases with previous surgery and HCV infection. MATERIAL AND METHODS: In a case-control study were included subjects that attended to the Central Blood Bank of the West Medical National Center, Mexican Institute of the Social Security in Guadalajara, Jalisco between july 2005 and september 2007. Cases were patients with positive hepatitis C antibody (anti-HCV) confirmed by recombinant immunoblot assay (RIBA) and/or nucleic acid test (HCV RNA); the control group was blood donors with negative antibody. An exhaustive questionnaire about risk factors for hepatitis C, was applied. The risk of HCV infection was determined with the Odds Ratio (OR) and multivariate analysis was made by logistic regression. RESULTS: We included 362 subjects, 211 cases and 151 controls; in 70 (33.2%) cases were found significant association between the anesthesia procedures and HCV infection in patients with previous surgery (OR adjusted 2.44, CI 95% 1.44 - 4.11) CONCLUSION: This is the first study in México that demonstrate association between history of anesthesia procedures and HCV infection in cases with previous surgery.

Needlestick injuries: a survey of doctors working at Tertiary Care Hospitals of Rawalpindi.

OBJECTIVES: To document frequency, nature and predisposing factors for needlestick injuries (NSI) in doctors working at tertiary care hospitals of Rawalpindi. METHODS: This cross sectional survey was conducted at Department of Medicine, Rawalpindi Medical College from July 2009 to April 2010. Five hundred doctors working at various tertiary care hospitals of Rawalpindi were contacted. Each doctor was provided a specifically designed proforma focusing on number, nature, and predisposing factors for NSI which was defined as percutaneous injury caused by hollow-bore needles, suturing needles, scalpel blades and lancets. Frequency and percentage of collected data was sought. RESULTS: Out of 500, 61.8% (n = 309) doctors returned the filled proformas. Females were 50.8% (n = 158). History of NSI was present in 85.1% (n = 263) participants of which most common was from syringe needle (47.52%; n = 125), surgical stitch needle (20.9%; n = 55), and surgical blade (9.5%; n = 25). Most of NSI took place while recapping needles (33%; n = 87), surgical procedures (27.7%; n = 73), and drawing blood samples (26.2%; n = 69). Majority of these doctors 42.5% (n = 112) attributed NSI to stress, 37.6% (n = 99) to over work, and 19.7% (n = 52) to carelessness. CONCLUSION: NSI due to syringe and surgical stitch needle are very frequent in doctors working at various tertiary care hospitals of Rawalpindi. Most of these are sustained while recapping needle and surgical procedures in stressful and overworked circumstances.
