Prospective case-control study on pain intensity after the use of promethazine in patients undergoing videothoracoscopy.

Objective: Effective and secure pain management following video-assisted thoracoscopic surgery (VATS) is crucial for rapid postoperative recovery. This study evaluated analgesic and sedative effects of sufentanil and promethazine in patient-controlled intravenous analgesia (PCIA) post-thoracic surgery, along with potential adverse reactions. Methods: In this prospective, randomized, controlled, double-blind, clinical study, 60 patients (American Society of Anesthesiologists status I-III) undergoing VATS were enrolled. The patients were randomized into experimental (Group P) or control (Group C) groups. PCIA was administered post-general anesthesia using a double-blind method. Group P received sufentanil (3 µg/kg) + promethazine (1 mg/kg) + 0.9% sodium chloride solution (100 mL total), while Group C received sufentanil (3 µg/kg) + 0.9% sodium chloride solution (100 mL total). PCIA settings included a 1-mL bolus and 15-min locking time. The primary outcomes were the visual analog scale (VAS) at rest and during coughing and sedation (Ramsay) scores at 6, 12, 24, and 48 h. The secondary outcomes were rescue drug use rate, hemodynamic parameters (mean arterial pressure and heart rate), percutaneous oxygen saturation, respiratory rate, and occurrence of adverse reactions. Results: Group P exhibited lower resting and coughing VAS scores at 6, 12, 24, and 48 h, plus decreased incidence of nausea and vomiting within 48 h post-surgery compared with Group C (p < 0.05). No significant differences were observed in pruritus, sedation (Ramsay) scores, mean arterial pressure, heart rate, oxygen saturation, or respiratory rate between the two groups (p > 0.05). Discussion: The combination of sufentanil and promethazine for postoperative intravenous analgesia could effectively reduce adverse effects such as nausea and vomiting, contributing to postoperative pain relief.

Pain and immune function in patients undergoing gastric cancer surgery following stellate ganglion block with total intravenous anesthesia.

BACKGROUND: Stellate ganglion block is a commonly used sympathetic nerve block technique that restores the balance of the sympathetic and vagal nervous systems of the body and inhibits sympathetic nerve activity. AIM: To analyze the effect of a stellate ganglion block combined with total diploma intravenous anesthesia on postoperative pain and immune function in patients undergoing laparoscopic radical gastric cancer (GC) surgery to provide a reference basis for the formulation of anesthesia protocols for radical GC surgery. METHODS: This study included 112 patients who underwent laparoscopic radical surgery for GC between January 2022 and March 2024. There was no restriction on sex. The patient grouping method used was a digital random table method, and the number of cases in each group was 56. The control group was administered total intravenous anesthesia, and the observation group compounded the stellate ganglion block according to the total intravenous anesthesia protocol. Postoperative hemodynamics, pain levels, and immune indices were compared between the groups. RESULTS: The heart rate and mean arterial pressure in the observation group after intubation were lower than those in the control group (P < 0.05). Pain levels were compared between the two groups at 2 hours, 12 hours, 24 hours, and 48 hours after surgery (P > 0.05). The number of CD3+, CD4+, and CD4+/CD8+ cells at the end of surgery was higher in the observation group than in the control group, and the number of CD8+ cells was lower in the observation group than in the control group (P < 0.05). There were no significant differences between the two groups in terms of propofol dosage, awakening time, extubation time, or postoperative adverse reactions (P > 0.05). CONCLUSION: The application of a stellate ganglion block combined with total intravenous anesthesia had no significant effect on postoperative pain levels in patients undergoing laparoscopic radical GC surgery. However, it can safely reduce the effect of surgery on the immune function of patients and is worth applying in clinical practice.

Cytokine landscape in hospitalized children with multisystem inflammatory syndrome.

The etiology of multisystem inflammatory syndrome in children (MIS-C), frequently observed following COVID-19 infection, remains elusive. This study unveils insights derived from cytokine analysis in the sera of MIS-C patients, both before and after the administration of intravenous immunoglobulin (IVIG) and glucocorticosteroids (GCS). In this study, we employed a comprehensive 45-cytokine profile encompassing a spectrum of widely recognized proinflammatory and antiinflammatory cytokines, as well as growth factors, along with other soluble mediators. The analysis delineates three principal cytokine-concentration patterns evident in the patients' sera. Pattern no.1 predominantly features proinflammatory cytokines (IL-6, IL-15, IL-1ra, granulocyte-macrophage colony-stimulating factor (GM-CSF), tumor necrosis factor α (TNFα), C-X-C motif chemokine ligand 10 (CXCL10/ IP-10), and IL-10) exhibiting elevated concentrations upon admission, swiftly normalizing post-hospital treatment. Pattern no. 2 includes cytokines (IL-17 A, IL-33, IFNγ, vascular endothelial growth factor (VEGF), and programmed death ligand (PD-L1)) with moderately elevated levels at admission, persisting over 7-10 days of hospitalization despite the treatment. Pattern no. 3 comprises cytokines which concentrations escalated after 7-10 days of hospitalization and therapy, including IL-1α, IL-1ß, IL-2, IL-13, platelet-derived growth factor AA/BB (PDGF AA/BB). The observed in cytokine profile of MIS-C patients showed a transition from acute inflammation to sustaining inflammation which turned into induction of humoral memory mechanisms and various defense mechanisms, contributing to recovery.

Optimizing Microfluidic Channel Design with High-Performance Materials for Safe Neonatal Drug Delivery.

INTRODUCTION: Designing the microfluidic channel for neonatal drug delivery requires proper considerations to enhance the efficiency and safety of drug substances when used in neonates. Thus, this research aims to evaluate high-performance materials and optimize the channel design by modeling and simulation using COMSOL multiphysics in order to deliver an optimum flow rate between 0. 3 and 1 mL/hr. METHOD: Some of the materials used in the study included PDMS, glass, COC, PMMA, PC, TPE, and hydrogels, and the evaluation criterion involved biocompatibility, mechanical properties, chemical resistance, and ease of fabrication. The simulation was carried out in the COMSOL multiphysics platform and demonstrated the fog fluid behavior in different channel geometries, including laminar flow and turbulence. The study then used systematic changes in design parameters with the aim of establishing the best implementation models that can improve the efficiency and reliability of the drug delivery system. The comparison was based mostly on each material and its appropriateness in microfluidic usage, primarily in neonatal drug delivery. The biocompatibility of the developed materials was verified using the literature analysis and adherence to the ISO 10993 standard, thus providing safety for the use of neonatal devices. Tensile strength was included to check the strength of each material to withstand its operation conditions. Chemical resistance was also tested in order to determine the compatibility of the materials with various drugs, and the possibility of fabrication was also taken into consideration to identify appropriate materials that could be used in the rapid manufacturing of the product. RESULTS: The results we obtained show that PDMS, due to its flexibility and simplicity in simulation coupled with more efficient channel designs which have been extracted from COMSOL, present a feasible solution to neonatal drug delivery. CONCLUSION: The present comparative study serves as a guide on the choice of materials and design of microfluidic devices to help achieve safer and enhanced drug delivery systems suitable for the delicate reception of fragile neonates.

Recommendation for the practice of total intravenous anesthesia.

This Recommendation was developed by the Japanese Society of Intravenous Anesthesia Recommendation Making Working Group (JSIVA-WG) to promote the safe and effective practice of total intravenous anesthesia (TIVA), tailored to the current situation in Japan. It presents a policy validated by the members of JSIVA-WG and a review committee for practical anesthesia management. Anesthesiologists should acquire and maintain the necessary knowledge and skills to be able to administer TIVA properly. A secure venous access is critically important for TIVA. To visualize and understand the pharmacokinetics of intravenous anesthetics, use of real-time pharmacokinetic simulations is strongly recommended. Syringe pumps are essential for the infusion of intravenous anesthetics, which should be prepared according to the rules of each individual anesthesia department, particularly with regard to dilution. Syringes should be clearly labeled with content and drug concentration. When managing TIVA, particularly with the use of muscle relaxants, monitoring processed electroencephalogram (EEG) is advisable. However, the depth of sedation/anesthesia must be assessed comprehensively using various parameters, rather than simply relying on a single EEG index. TIVA should be swiftly changed to an alternative method that includes inhalation anesthesia if necessary. Use of antagonists at emergence may be associated with re-sedation risk. Casual administration of antagonists and sending patients back to surgical wards without careful observation are not acceptable.

Comparison of Intravenous Dexmedetomidine Versus Dexmedetomidine-Dexamethasone Combination for Preventing Postoperative Nausea and Vomiting in Adult Patients After Abdominal Surgeries.

INTRODUCTION:  Postoperative nausea and vomiting (PONV) is a common problem following general anesthesia and is one of the most unpleasant side effects that affects the patient after surgery and is the worst memory of the hospital stay. The present prospective randomized comparative study was designed to compare the effect of intravenous dexmedetomidine with dexmedetomidine-dexamethasone combination for preventing PONV following abdominal surgeries in adult patients and evaluating their sedative and analgesic effects. METHODOLOGY: A total of 75 patients (aged 18-65 years) were assigned to undergo this comparative study via block randomization using a sealed envelope system. They were divided into three groups of 25 each: group A (control) received normal saline, group B received dexmedetomidine, and group C received a combination of dexmedetomidine with dexamethasone over 10 minutes after inducing general anesthesia before skin incision. The primary outcome was to assess PONV, where nausea was assessed by the numerical rating scale and vomiting by the number of gastric content expulsions. The secondary outcome, which is postoperative sedation and pain, was assessed by the Ramsay Sedation Score and Visual Analog Score, respectively, for 24 hours postoperatively. RESULT:  During the first 24 hours after surgery, the incidence of PONV was similar in both dexmedetomidine and combination groups but lower than the control group. Postoperative sedation and analgesia were both statistically and clinically adequate and similar in dexmedetomidine and combination groups. No major side effects requiring pharmacological intervention were reported. CONCLUSION:  Dexmedetomidine alone is as effective as its combination with dexamethasone in preventing PONV in adult patients following abdominal surgeries.

A Case of Relapse Pseudomonas aeruginosa Tricuspid Valve Endocarditis After AngioVac Vegectomy and Antibiotic Treatment in a Patient Using Intravenous Drugs.

Infective endocarditis (IE) is a bloodstream infection affecting the valves of the heart. IE is highly associated with morbidity and mortality if not properly managed. Pseudomonas aeruginosa (P. aeruginosa) as a cause of IE is extremely rare. This is a case of IE involving a male patient with a history of intravenous drug use (IVDU), secondary to P. aeruginosa, with associated relapse of bacteremia and native tricuspid valve endocarditis, complicated by septic pulmonary emboli, despite undergoing recent vegetation debulking using the AngioVac system (AngioDynamics, Inc., New York, USA) along with six weeks of IV antibiotics and no IVDU since then being on treatment.

Emergency Artery Ligation and Distal Revascularization for a Limb-Threatening Brachial Artery Mycotic Aneurysm Rupture.

Brachial artery mycotic aneurysms are very rare and even more uncommon to present initially with bleeding or rupture. Initial presentation of ruptured brachial artery mycotic aneurysm in an active intravenous drug abuser is managed with brachial artery ligation with an option of revascularization later. Distal circulation is not commonly threatened as there is a presence of collaterals to perfuse the distal limb. In this case report, we present a case of limb-threatening brachial artery mycotic aneurysm rupture that needed emergency revascularization surgery.

Perinatal Outcomes Following Intravenous Iron for Treatment of Iron Deficiency With and Without Anemia.

OBJECTIVE: To determine maternal and neonatal outcomes in individuals with iron deficiency receiving antepartum intravenous (IV) iron supplementation, stratified by the degree of anemia. STUDY DESIGN: Retrospective cohort study of iron-deficient pregnant patients who received at least one IV infusion of iron (iron sucrose, low molecular weight iron dextran [LMWID], or ferric carboxymaltose) during their pregnancy from January 1, 2011 through June 16, 2022. Our primary outcomes included both neonatal composite morbidity and maternal composite morbidity in the context of maternal anemia. RESULTS: Patients who received LMWID had fewer infusion visits, received higher total doses of iron and had a more substantial correction of hemoglobin compared to those who received iron sucrose (p < 0.01). Maternal anemia at the time of admission was not associated with neonatal composite morbidity. However, there was a significant association between anemia status and maternal composite outcome (p = 0.05). Anemia at time of delivery was associated with the likelihood of requiring a blood transfusion (p = 0.01). CONCLUSION: This study reinforces previous findings emphasizing the adverse effects of iron deficiency on maternal health and the role of IV iron in reducing these risks.

Acute and chronic ocular outcomes in SJS/TEN patients treated with oral ciclosporin vs intravenous immunoglobulin.

Background/Aim: To evaluate differences in ocular complications of Stevens Johnson Syndrome (SJS)/Toxic Epidermal Necrolysis (TEN) patients receiving either systemic IVIG or Ciclosporin (CsA) as initial treatments. Methods: Retrospective review of consecutive patients admitted for SJS/TEN at the Singapore General Hospital (SGH) from 2011 to 2017 who received either IVIG or Ciclosporin at the onset of the disease and had ophthalmological follow-up of at least 6 months were included. Acute ocular severity of SJS/TEN was graded using the Gregory grading score; chronic ocular complications were graded using the Sotozono system. Results: A total of 18 subjects were included for analysis, with eight in the IVIG group and 10 in the CsA group. There were no significant differences in acute Gregory severity grading between the two groups. The CsA group had a trend towards worse overall chronic Sotozono grading scores compared to the IVIG group (median [IQR]: 2 [0-3] vs. 1 [0-6.5], p = 0.27), with a higher incidence of acute severe cornea involvement (60% vs. 25%, p = 0.93) and chronic corneal and eyelid involvement in the former than the latter. SJS/TEN patients with worse acute ocular involvement were more likely to have TEN and perianal mucosal involvement (50% vs. 0, p = 0.01). Conclusion: Compared to those who received IVIG, SJS/TEN patients who received CsA at the acute disease stage, seemed to have worse acute corneal and chronic corneal and eyelid complications. Larger studies are needed to confirm this finding.

Research on PIVAS risk assessment and control strategy based on quality risk management (QRM).

OBJECTIVE: This study aims to evaluate the effectiveness of the Quality Risk Management (QRM) system in hospital pharmacy intravenous admixture services (PIVAS). METHODS: Failure Modes and Effects Analysis (FMEA) and risk matrix methods were used to systematically assess the critical risk points in PIVAS. By collecting and comparing relevant data from 2019 to 2023, key performance indicators (KPIs) before and after the implementation of the QRM system were quantitatively evaluated. RESULTS: The results showed that the safety and efficiency of pharmacy services significantly improved after the implementation of the QRM system. The medication error rate significantly decreased from 3.2% to 1.1%, the average medication preparation time reduced from 15.5 min to 8.2 min, and staff satisfaction increased from 6.0 to 8.5 points. Other indicators, such as cross-contamination rates and handling errors, also showed significant improvement (all outcomes p < 0.001). DISCUSSION: Systematic risk management effectively enhanced the operational performance of PIVAS, reduced medication errors, and improved the quality of healthcare services. This study highlights the key role of QRM in enhancing medication safety and productivity, providing empirical support for the implementation of similar systems in other healthcare institutions.

The burden of systemic therapy administration route in treating HER2-positive breast cancer (for patients, healthcare professionals, and healthcare system): a systematic literature review.

Introduction: Breast cancer (BC) is one of the leading causes of cancer and is the first cause of death from malignant tumors among women worldwide. New cancer therapies receive regulatory approval yearly and to avoid health disparities in society, the health systems are challenged to adapt their infrastructure, methodologies, and reimbursement policies to allow broad access to these treatments. In addition, listening to patients' voices about their therapy preferences is essential. We aim to investigate the administration route preferences [subcutaneous (SC) or intravenous (IV)] among patients diagnosed with HER2 positive BC and healthcare professionals (HCPs) and to investigate healthcare resources utilization (quality and quantity) for each route of administration (SC or IV) for treating those patients. Methods: We conducted a systematic literature review focused on clinical trials and observational and economic studies, using PubMed (MEDLINE), Cochrane Library, Virtual Health Library (VHL), Scientific Electronic Library Online (SciELO), and Latin American and Caribbean Health Sciences Literature (LILACS) databases based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Results: The literature review included 25 studies in the analysis. Studies have reported that patients and HCPs prefer the SC route of administration to IV because it saves time in terms of chair time, administration, and preparation and is less painful. In addition, SC administration might be a more cost-saving option when analyzing direct and indirect costs. Discussion: As BC stands as a significant global health concern and the leading cause of cancer-related deaths in women worldwide, understanding and incorporating patient and HCPs preferences in the choice of administration route become paramount. The observed preference for SC administration not only aligns with the imperative of adapting health systems to facilitate broad access to new cancer therapies but also underscores the importance of considering patient experiences and economic implications in shaping treatment strategies. These insights are crucial for healthcare policymakers, clinicians, and stakeholders in optimizing healthcare resources and enhancing the overall quality of BC care.

Intravenous lipomas of head and neck: an exceptional entity and its clinical implications.

Intravenous lipomas (IVLs) of the head and neck are uncommon benign tumors that develop within the venous walls, often detected incidentally during imaging for unrelated issues. While usually asymptomatic, these IVLs can cause congestive venous symptoms like swelling, paresthesia or pain in the head and neck and upper limbs, or even venous thromboembolism. The precise diagnosis of IVLs is predominantly achieved through computed tomography (CT) and magnetic resonance imaging (MRI), with CT being the most frequently used method. Symptomatic patients generally undergo open surgery with excision of the IVL followed by venous reconstruction, which has shown safe and effective outcomes. However, the management of asymptomatic IVLs remains controversial due to the limited number of reported cases. Despite this, there is a notable trend toward recommending surgical removal of IVLs to prevent complications and rule out malignancy, driven by the challenges of differentiating IVLs from malignant tumors using imaging alone. This review highlights the key differential imaging characteristics of IVLs and the main surgical techniques to remove the tumor and repair the vascular defect. Further research is necessary to establish a robust, evidence-based approach for treating asymptomatic IVLs, balancing the risks of surgery against the potential for future complications.

A Portable Fluid Administration System for Prolonged Intravenous Fluid Administration in Subadult and Adult White Rhinoceroses (Ceratotherium simum).

While translocations of white rhinoceroses have become an important conservation tool, dehydration during long-distance transports has been identified as a welfare concern. Intravenous (iv) fluid administration might therefore be useful to mitigate dehydration; however, special requirements need to be met to make iv fluid administration suitable for large, wild rhinoceroses during transport. Requirements include a portable and robust system that is capable of delivering high flow rates, is easy to set up, and remains patent and operating for long periods of time while allowing the animals to freely stand or lay down in the transport crates. Due to the lack of suitable fluid administration systems, we developed a custom-made system consisting of 8 L drip bags, a three-part, 4.4-m-long, large bore and partially coiled administration set, and a robust, battery-operated infusion pump, which allowed us to successfully administer iv fluids at a maintenance rate of 1-2 mL/kg/h to eight rhinoceroses for 24 h during a mock transport. While iv fluid administration in transported rhinoceroses is time intensive and the large amount of drip bags required during lengthy transports might pose a limitation, the developed system may be useful for the long-distance transport of small groups of rhinoceroses. Furthermore, this system would be of value for injured or sick rhinoceroses, which require parenteral fluid therapy when commercially available infusion pumps cannot provide the large fluid volumes needed.

Intravenous fosfomycin indications and treatment outcomes in pediatric usage: analysis from a single center in Turkey.

Current data on fosfomycin usage in children are limited. We present data on the clinical use of intravenous (IV) fosfomycin in children. Hospitalized patients who received ≥3 days of IV fosfomycin between April 2021 and March 2023 were analyzed retrospectively. Forty-three episodes of infection in 39 patients were evaluated. The mean age of the patients was 5.35 (10 days to 17.5 years) years, and 54% were male. Infections were hospital-acquired in 79% of the episodes. Indications for fosfomycin were urinary tract infection (35%), bacteremia (32.6%), catheter-related bloodstream infection (16.3%), soft tissue infection (4.7%), sepsis (4.7%), surgical site infection (2.3%), burn infection (2.3%), and pneumonia (2.3%). Klebsiella pneumoniae was identified in 46.5% of the episodes, and a pan-drug or extensive drug resistance was detected in 75% of them. Carbapenem was used before fosfomycin at significantly higher rates in K. pneumoniae episodes (P = .006). Most (88.5%) patients received fosfomycin as a combination therapy. Culture negativity was achieved in 80% of episodes within a median treatment period of 3 (2-22) days, which was significantly shorter in K. pneumoniae episodes (P < .001). Treatment-related side effects were seen in 9.3% of the episodes. Side effects were significant after 3 weeks of treatment (P = .013). The unresponsivity rate to fosfomycin was 23.3%. Nine (21%) of the patients who were followed up in the intensive care units mainly died because of sepsis (56%). IV fosfomycin is an effective agent in treating severe pediatric infections caused by resistant microorganisms. Fosfomycin can be used in various indications and is generally safe for children.

Exploring the "Two-Hit" Phenomenon of Guillain-Barré Syndrome Following Respiratory Syncytial Virus and Influenza Vaccinations.

Guillain-Barré syndrome (GBS) is a neurological disorder characterized by peripheral, autoimmune-mediated demyelinating polyneuropathy, which can cause muscle weakness and paralysis. While most cases are triggered by respiratory or gastrointestinal infections, vaccinations have also been linked to GBS pathogenesis. The association of the influenza vaccine and GBS, notably prevalent during the 1976 United States swine flu pandemic, has significantly decreased with contemporary seasonal influenza vaccines. At the same time, cases of GBS have been reported with newer vaccines, like the recently approved respiratory syncytial virus (RSV) vaccines. However, their exact relationship with autoimmune demyelinating polyneuropathy remains unknown. In this report, we present a case of a 60-year-old man who developed GBS two weeks after receiving the new Pfizer's RSV vaccine in conjunction with the influenza vaccine for the first time.

Severe Acute Porphyria Exacerbation Post Intravenous Iron Infusion: A Case Report.

This case report describes a 28-year-old man with erythropoietic porphyria (EPP). After receiving an intravenous iron infusion, he experienced a significant acute aggravation of his condition. The patient had a vesicular rash on the face and arms with severe itching and burning feelings in addition to nausea, vomiting, and black-colored vomit. Abnormal liver function tests and anemia were found in the lab tests. Quick diagnosis and multidisciplinary care from dermatology, gastrointestinal, and hematology experts were essential. Strict light avoidance, symptom management techniques, and cessation of intravenous iron were all part of the treatment plan. The patient's symptoms subsided over a period of 12 months, and he resumed his regular activities. In managing EPP, key learning points stress the importance of vigilance in spotting trigger variables, prompt diagnosis, light avoidance, consistent follow-up, and genetic counseling.

Optimizing Infusate Flow Patterns for Minimizing Vein Wall Trauma: An Exploratory Study with a Modified off-Axis Catheter Tip Opening.

Objective: Modifying the PIVC tip to direct infusates toward areas of highest hemodilution may reduce vein wall damage. This study compared flow patterns between a traditional PIVC with a central opening and one with an off-axis aperture. Methods: This was an exploratory observational analysis conducted at a tertiary care emergency department (ED) comparing flow patterns of two intravenous catheters: PIVC 1 (2.95 cm 20 gauge [Autoguard, Becton Dickinson]) and PIVC 2 (3.68 cm 20 gauge [Osprey, SkyDance Vascular]). Adult ED patients with PIVCs placed via traditional palpation/visualization method and with ultrasound capturing the flushing were eligible participants. Ultrasounds were reviewed to determine vein, catheter, and flow characteristics. The primary outcome was angle of the infusate leaving the catheter. Secondary outcomes included direction of catheter tip against vein wall, distance away from vein wall, vasospasm, and laminar/turbulent flow. Results: Data from December 2023 included 28 catheters (10 PIVC 1, 18 PIVC 2). The average patient age was 53.7 years; 53.6% were female. Vein diameter/depth were similar: 0.35 cm/0.41 cm for PIVC 1 and 0.37 cm/0.47 cm for PIVC 2. The catheter tip pointed posteriorly towards the vein wall in 60% of PIVC 1 vs 11.1% in PIVC 2 (P=0.018). The angle of infusate flow away from the vein wall was 0.20° (SD 0.63) for PIVC 1 and 7.61° (SD 5.71) for PIVC 2 (P<0.001). Flow at 0° occurred in 90% of PIVC 1 vs 16.7% in PIVC 2 (P<0.001). Conclusion: In this exploratory investigation, a peripheral vascular access device with an off-axis tip aperture of demonstrated a sharper infusate flow angle away from the vein wall compared to a traditional central opening device. This redirection may reduce vein wall trauma and complications, though further research is needed to pair clinical outcomes with this technology.

Peripheral intravenous catheter clinical care standard adherence in emergency departments: A qualitative study underpinned by the behaviour change wheel.

AIM: To explore the barriers and facilitators influencing emergency department clinicians' adherence to the Australian Peripheral Intravenous Catheter (PIVC) Clinical Care Standard, using the Behaviour Change Wheel (BCW). BACKGROUND: Suboptimal PIVC practices are frequently linked to a range of patient-important adverse outcomes. The first Australian Peripheral Intravenous Catheter Clinical Care Standard was introduced in 2021, aiming to standardize practice. However, a recent national survey revealed a lack of adherence to the Standard among emergency department clinicians. DESIGN: A qualitative descriptive study. METHOD: The study was conducted across two Australian emergency departments in 2023. Utilizing purposive sampling, semi-structured interviews were conducted. The analysis incorporated both deductive and inductive approaches, mapping the findings to the BCW. FINDINGS: Interviews with 25 nurses and doctors revealed nine key subthemes. The main barriers were the stressful environment, insufficient education and training, and the absence of a feedback mechanism. The main facilitators were recognition of suboptimal practice, belief in the importance of patient engagement, and the desire to improve practice. CONCLUSION: Multiple complex factors have an impact on clinicians' adherence to the Standard. The identified interventions will serve as a guide for future implementation of the Standard. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: The findings inform healthcare organizations of the significance of implementing strategies to enhance clinicians' acceptance of the Standard. Clinicians should consider incorporating the multifaceted interventions developed in accordance with the BCW for future implementation projects. IMPACT: Promoting adherence to standards opens avenues to challenge suboptimal practice and has the potential to instigate a culture shift in the fundamental skills of frontline clinicians. REPORTING METHOD: The study is designed and reported according to the Consolidated Criteria for Reporting Qualitative Research checklist. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.
