Work-related stress among nurses: a comparative cross-sectional study of two government hospitals in Ghana

BackgroundOccupational stress is increasing globally and affecting all workplaces and countries’ health professionals. Despite its significant impact on healthcare delivery, limited studies have actually compared the prevalence, causes, effects, and coping strategies of stress among nurses working in hospitals with variation in capacity and function in Ghana. We, therefore, examined and compared the prevalence, causes, effects and coping strategies of occupational stress among nurses working in a secondary care and tertiary hospital in Ghana.MethodsWe conducted a health facility-based cross-sectional study among 248 nurses from two hospitals (Volta Regional Hospital [VRH] and Ho Teaching Hospital [HTH]). The Perceived Stress Scale (PSS) and Weiman Occupational Stress Scale (WOSS) were used to measure the nurses’ stress levels and causes of occupational stress respectively. A self-reported checklist was used to measure both the effects of stress and strategies. Descriptive analyses and t-tests were performed, and statistical significance was measured at the 0.05 level.ResultsThe majority of nurses 77.8% experienced a moderate level of perceived stress. The total individual mean scores of the nurses from the two hospitals (VRH = 3.02 and HTH = 3.09) were 34% and 37% respectively higher than the established WOSS individual average of 2.25. Nursing difficult patients (t=-1.1196, p = 0.037), Unfriendly relationships with superiors, colleagues, and subordinates (t=-2.3333, p = 0.020), working with incompetent staff (t=-1.3129, p = 0.037) were the statistically significant stressors among nurses in the HTH. Whereas, long work hours (t = 2.0841, p = 0.038) and needle-stick injuries (t = 2.6669, p = 0.008) were the statistically significant stressors among nurses from the VRH. Headache (VRH = 73.8% and HTH = 97.9%), Fatigue (VRH = 68.9% and HTH = 83.5%), Frustration VRH = 50.5% and HTH = 68.3%) and Lack of Concentration (VRH = 81.6% and HTH = 80.0%) were most common effects of occupational stress reported.ConclusionThe majority of nurses reported moderate levels of stress, with the two institutions’ stressors differing. Key causes of stress were needle stick injuries, long hours, dealing with challenging patients and strained interpersonal relationships. Common side effects were headaches, exhaustion, irritability, and trouble focusing. To accelerate progress towards achieving the sustainable development goal (SDG) 3.4 of promoting mental health and well-being by 2030, the 2012 Mental Health Act of Ghana and the Occupational Health and Safety Regulations, should fully and effectively be implemented in health facilities across the country.

A Mixed Method Study in Young Children Participating in Clinical Research During A Kidney Transplantation Trajectory.

Regulations designed to protect children participating in clinical research often restrict the availability of research data necessary for the development of age-specific therapies and drug dosing. Few data exist on how children experience participation in clinical research, and studies investigating young children undergoing an intensive medical treatment are lacking. Mixed methods with semi-structured interviews and DISCO-RC questionnaires were used to explore young children's and their parents' experiences in clinical research participation during a kidney transplantation trajectory. Nine children and their parents were interviewed. Children's median age at kidney transplantation was 4 years (IQR 4,7); age at interview was 7 years (IQR 6,9). Thematic content analysis of interviews revealed that most children were unaware of having participated in a study. Both children and their parents frequently were unaware whether procedures were standard care or research related. The additional burden attributed to study participation varied from not at all to heavy in combination with intensive medical treatment. Positive experiences included kind healthcare professionals, effective distraction techniques, educational aspects, contributing to science and extra check-ups. Most reported negative experiences were conflicting communication, spending much time in the hospital, missing school and suboptimal planning. Venous puncture was stressful for all children, whereas the discomfort of other procedures varied. Pediatric clinical research design should focus on education and fun during research procedures, smart planning, consistent communication, close collaboration between clinical and research team and age appropriate distraction techniques.

Virtual reality technology reduces the pain and anxiety of children undergoing vein puncture: a meta-analysis

BackgroundPain management is an important part of nursing care for children. The objective of this study was to systematically assess the impact of virtual reality (VR) technology on alleviating the pain and anxiety experienced by children during venipuncture procedures.MethodsThis study searched Pubmed, Web of Sciences, Scopus, The Cochrane Library, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Embase, Medline, China National Knowledge Infrastructure (CNKI), Wanfang, Weipu and China biomedical databases on the randomized controlled trials (RCTs) of virtual reality technology for relieving pain and anxiety associated with venous puncture for children up to July 6, 2024. Risk of bias tool recommended by Cochrane library was used to evaluate the RCT quality. RevMan 5.3 software was used for statistical analysis.ResultsA total of 10 RCTs involving 874 children were included. 429 children received VR intervention during vein puncture. VR was beneficial to reduce the children’s self-reported pain scores [SMD=-0.48, 95% CI (− 0.61, − 0.35)], children’s caregivers reported needle-related pain level [SMD=-0.93, 95% CI (-1.45, − 0.42)], children’s self-reported anxiety scores [SMD=-0.45, 95% CI (− 0.65, − 0.25)], children’s caregivers reported needle-related anxiety level [SMD=-0.47, 95% CI (− 0.73, − 0.21)]. Egger regression tests indicated that there were no publication biases in the synthesized outcomes (all P > 0.05).ConclusionsVR technology has been shown to effectively mitigate the pain and anxiety experienced by children during venipuncture. Despite the positive findings, more research is needed to better understand the role of VR in children undergoing venipuncture.

Frequency of occupational health hazards and factors responsible among the waste handlers at the tertiary care hospitals of Karachi.

Hospital waste handlers (HWHs) are in contact with contaminated waste that put them at risk for occupational health hazards. The objective of the study was to determine the frequency of occupational health hazards and identify factors contributing to them among the HWHs at tertiary care hospitals of Karachi. A cross sectional survey was conducted from January 2021 till June 2022 on 417 conveniently selected HWHs of the public and private tertiary care hospitals of the Karachi including three Public sector hospitals (Civil Hospital Karachi, National Institute of Child Health, Jinnah Post Graduate Medical Center) and five private sector hospitals (Sohail University Hospital, Darulsehat Hospital, Kharadar General Hospital, Patel Hospital and Hamdard University Hospital) using a structured questionnaire. Chi Square test was applied to determine the differences in occurrence of different hazardous outcomes (Needle stick injury, Sharp Injury, Eye Symptoms, Skin symptoms, Cough) between different groups of age, gender, type of hospitals and status of being trained in Hospital Waste Management (HWM). Around half of the HWHs (52.6%) labeled the bins of the waste according to their level of hazard. Only 17.9% disinfected the infected waste. The proportion of participants who experienced needle stick and sharp injury in the last six months was 16.3% and 15.8% respectively. Majority of them used disposable gloves (95.7%) and face masks (94.3%). One thirds had access to aprons while only 10.5% had access to protective shoes at their work place. HWHs of private sector were significantly less likely to experience Needle stick injuries, skin symptoms, cough, breathing difficulty and throat burning. The HWM practices in tertiary care hospitals of Karachi is far from being satisfactory. HWHs must be trained and monitored for safe disposal of waste.

Ultrasound-Guided Versus Palpation-Guided Techniques to Achieve Vascular Access in Children Undergoing Cardiac Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Pediatric heart surgery is a vital therapeutic option for congenital heart disease, which is one of the most prevalent causes of death in children. Arterial cannulation (AC) and central venous catheter (CVC) are required in pediatric cardiac surgery for continuous monitoring of the central venous pressure (CVP), replacement of fluid or blood products, close hemodynamic monitoring, and frequent sampling for arterial blood gases (ABG). A systematic review and meta-analysis synthesizing evidence from randomized controlled trials (RCTs) retrieved from PubMed, Embase Cochrane, Scopus, and WOS until February 2024. Risk ratio (RR) was used to report dichotomous outcomes, and mean difference (MD) was used to report continuous outcomes, both with a 95% confidence interval (CI) using the random-effects model. Thirteen RCTs with 1060 children were included. Regarding arterial cannulation, the ultrasound-guided technique (US) was associated with a statistically significant increase in successful cannulation [RR: 1.31 with 95% CI (1.10, 1.56), P < 0.0001], and first-attempt success [RR: 1.88 with 95% CI (1.35, 2.63), P < 0.0001]. However, US was not associated with any statistically significant difference in venous cannulation in both outcomes with [RR: 1.13 with 95% CI (0.98, 1.30), P = 0.10], [RR: 1.53 with 95% CI (0.86, 2.71), P = 0.15] respectively. Moreover, US was associated with a statistically significant decrease in the number of attempts either in arterial cannulation with [MD: -0.73 with 95% CI (-1.00, -0.46), P < 0.0001] or in venous cannulation with [MD: -1.34 with 95% CI (-2.55, -0.12), P = 0.03], and the time of attempted cannulation also either in arterial cannulation with [MD: -2.27 with 95% CI (-3.38, -1.16), P < 0.0001] or in venous cannulation with [MD: -4.13 with 95% CI (-7.06, -1.19), P < 0.0001]. US guidance improves successful cannulation rates and first-attempt success in arterial access and reduces the number of attempts and procedural time for arterial and venous access. It was also associated with a lower incidence of complications and procedure failure, particularly in arterial access. However, it was associated with a higher incidence of venous puncture.

Study on needle stick injuries during surgery and blunt needle use for reducing occupational exposure and hygiene benefits.

The conventional round suture needle poses a significant risk of needle stick injuries among surgical physicians, identified as a global occupational hazard by the World Health Organization, increasing hospital costs and exposure to bloodborne pathogens. While novel blunt suture needles have shown promise in reducing these risks, their adoption is limited domestically, prompting a study to compare their efficacy against traditional sharp needles in reducing needle stick injuries among surgical physicians. To investigate suture needle stick injuries among surgical doctors during operations and assess the application effectiveness of a novel blunt suture needle. A total of 106 surgical department physicians from March 2021 to February 2023 participated in the study. After completing a questionnaire survey on suture needle injuries during surgery, the participants were divided into two groups. Over a 6-month intervention period, the control group used regular round needles while the study group utilized novel blunt suture needles. Subsequently, suture needle injury incidence rates and economic hygiene benefits were compared between the two groups. The suture needle injury questionnaire survey showed that over the past 6 months, among 106 surgical department physicians, 20 needle stick injuries occurred, yielding an incidence rate of 18.87%. The highest incidence (65.00%) was during suturing incisions longer than 10 cm, primarily when visibility was poor (70.00%). Surgeons linked most injuries (60.00%) to prolonged surgical duration causing fatigue. Although 85.00% detected injuries within 1 minute, only 40.00% were reported, often due to perceived reporting complexity. Following intervention, the study group had significantly fewer injuries per surgery and lower occupational exposure costs compared to the control group (p< 0.05). Surgical department physicians commonly sustain suture needle injuries while suturing incisions of 5-10 cm length under poor visibility, exacerbated by prolonged surgical duration. Despite detecting most injuries within 1 minute, only 40% are reported. The implementation of novel blunt suture needles significantly decreases injury rates, resulting in reduced occupational exposure costs and favorable safety and economic hygiene outcomes.

Financial impact of needle stick injury on a tertiary care teaching hospital

BackgroundAccidental needle stick injuries (NSIs) are an occupational hazard for healthcare workers (HCWs). Despite the implementation of preventive measures, NSIs still continue to occur in health care settings. The cost incurred by an institute for the management of occupational exposure to blood borne pathogen is a significant economic burden.This retrospective study was aimed to estimate the prevalence, factors associated with NSIs and cost burden on hospital due to NSIs. Material and methodsRetrospective data of all reported NSIs among HCWs between January 2019 and December 2021 in a tertiary care hospital was collected and analyzed. CDC definition was used to calculate direct & indirect cost. Results& Discussion- A total 205 NSIs were reported between January 2019 and December 2021. Nurses were the most affected category of HCWs. The maximum number of NSI cases (18.54 %) occurred during handling of biomedical waste. Both the source and the affected HCWs were tested and it was found that the source was seropositive in 30(14.63 %), seronegative in 128 (62.44 %) cases and in 47(22.93 %) cases there was an unknown source resulting in NSI. A total of 13, 21,206 INR, which included both direct and indirect cost, spent by hospital in the management of NSI's, over a period of 3yrs. ConclusionSurveillance and analysis of NSI is very crucial for the planning of both preventive measures and training modules. Managing NSI generates significant cost. Hepatitis B vaccination for all healthcare workers plays major role in reducing cost of managing NSIs.

Practices for preventing Hepatitis B infection among health science students in Ethiopia: Systematic review and meta-analysis.

Hepatitis B virus infection remains a significant public health concern globally, particularly among healthcare workers, including health science students who are at high risk due to their exposure to infected patients and contaminated medical equipment. In Ethiopia, where the burden of HBV infection is substantial, preventive practices among health science students are critical for minimizing transmission and ensuring a healthy workforce. However, there is a lack of comprehensive evidence regarding the effectiveness of these practices specifically among this population in Ethiopia. Therefore, this study aimed to provide a systematic review and meta-analysis of preventive measures for Hepatitis B infection among Health Science Students in Ethiopia. This study followed the guidelines outlined in the PRISMA checklist and focused on research conducted within Ethiopia. Seven relevant studies were identified through comprehensive searches across various databases including Google, Medline, PubMed, and Scholar. Data retrieval was systematically conducted using a checklist, and analysis was performed using STATA version 14. Heterogeneity was assessed using both the Cochrane Q test and the I2 statistic. Additionally, publication bias was evaluated using Egger's weighted regression, a funnel plot, and Begg's test. In this meta-analysis and systematic review, we identified a total of 515 research articles, of which seven studies met the eligibility criteria for analysis. The overall pooled magnitude of practices aimed at preventing Hepatitis B infection among Health Science Students in Ethiopia was 41.21% (95% CI: 30.81-51.62). Factors significantly associated with these practices included better understanding of Hepatitis B infection prevention (OR = 1.99, 95% CI: 1.20-3.29), age group 20-24 years (OR = 5.79, 95% CI: 2.43-13.78), needle stick injury exposure (OR = 3.43, 95% CI: 1.10-10.70), and students enrolled in medicine or public health officer departments (OR = 4.20, 95% CI: 2.65-6.65). Our analysis indicates that only 41.21% of Health Science students in Ethiopia adhere to Hepatitis B prevention practices. To improve these practices, it is essential to mandate vaccination, provide targeted training on infection prevention, and increase awareness of vaccine uptake. Tailored educational programs should equip students with practical strategies. Additionally, intelligent interventions must address factors influencing preventive practices. Collaboration between institutions and ongoing monitoring is crucial to ensuring success.

A Fatal Case of Powassan Virus Encephalitis

The Powassan virus (POWV) is part of the Flaviviridae family. It is mainly transmitted via tickbite but can rarely be spread person-to-person through blood transfusions. Initial symptoms include fever, headache, and vomiting. It can cause severe symptoms, including confusion, aphasia, and seizures. Approximately 1 out of 10 people with severe disease die. From 2010 to 2020, 194 Powassan virus cases have been reported to the Center for Disease Control (CDC), with 22 of them resulting in death. In this case report, we discuss a 39-year-old female who presented with fever, myalgia, and confusion. During her hospitalization, she developed tonic-clonic seizures, which required sedation and intubation. A central venous catheter was inserted due to poor intravenous access, and in the process of placing it, the provider sustained a needle stick injury. The patient was eventually diagnosed with POWV encephalitis and transferred to a higher level of care, where a brain perfusion study showed an absence of brain flow consistent with brain death. After a discussion with the family, the decision was made to extubate the patient terminally. The provider who sustained the needle stick injury reported no concerning symptoms two years after the event.

Prevalence and associated factors of needlestick and sharp object injuries among healthcare workers in Ethiopia: a systematic review and meta-analysis.

Needlestick and sharp object injuries affect healthcare workers. However, there are limitations in the evidence available for informed decision-making by stakeholders, as individual research shows inconsistent results. Therefore, this study aims to assess the pooled prevalence of needlestick and sharp object injuries and their associated factors. MEDLINE/PubMed, EMBASE, Web of Science, Google Scholar, and other databases were searched from 5 September 2023 to 10 October 2023 using the following search terms: "Prevalence" OR "Burden" OR "Magnitude" AND "Associated factors" OR "related factors" OR "Risk factors" OR "determinants" OR "Predictors" AND "Needle stick Injury" OR "Sharp Injury" OR "Health care Workers" OR " Health Care Personnel" OR "Nurses" OR "Professional" AND "Ethiopia". The pooled prevalence of needle sticks and sharp objects injury was 40.5 (95% CI: 35.0, 45.9). Needle-stick (AOR, 2.3; 95% CI: 1.6, 3.3, P < 0.001], absence of routine precaution [AOR, 2.3; 95% CI: 1.1, 4.5, P < 0.01] and lack of training (AOR = 2.4; 95% CI: 1.4, 4.1, p < 0.001) had increased odds of needle-sticks and sharp objects injury. Forty percent of healthcare workers in Ethiopia have experienced needlestick and sharp object injuries. The identified factors included recapping, absence of routine precautions, and lack of training. PROSPERO, identifier (CRD42023462311).

Incidence, Knowledge, Attitude and Practice of Healthcare Workers Regarding Needle Stick Injuries at a Tertiary Care Hospital in Riyadh, Saudi Arabia

Background: A needle stick injury is a serious occupational health hazard in health care settings. Health care workers are at risk of bloodborne diseases and the psychological consequences of these injuries. Objectives: we aimed in this study to assess the prevalence of NSI among health care workers in King Saud Medical City and to assess their knowledge, attitude and practices regarding needle stick injuries. Methods: A cross-sectional study was conducted from 17th August 2022 until 30th November 2023. A structured questionnaire from Saudi Ministry of Health guidelines was used to collect the data. The content validity was evaluated by four academics from King Khalid University in Abha, and some minor changes were made. Results: As regard the prevalence of NSI, out of 220 participants, 132 individuals did not report any needle-stick injuries (NSI). While 92.3% of participants accurately defined NSI and acknowledged blood-borne disease transmission risks, only 39.1% followed preventive measures like recapping needles and proper disposal. There were knowledge gaps observed, with varying awareness levels on Hepatitis B and C prevention. Participants demonstrated awareness of post-exposure guidelines but lacked knowledge on immediate actions to take post-injury. Attitudes towards NSI varied, with a significant percentage 44.1% prioritizing patient care over healthcare worker safety. Interestingly, significant support was shown for immediate reporting of sharp injuries and the belief that NSIs are preventable. In terms of practice, adherence to safe needle practices varied, with the majority 90.9% using assigned disposal containers and being vaccinated against Hepatitis B, but not all receiving recent training on safe devices. Conclusion: This study revealed that NSIs remain a prevalent occupational health hazard among healthcare workers. Although a significant number of participants demonstrated adequate knowledge and awareness of NSIs and bloodborne disease transmission risks, there were noticeable gaps in their implementation of preventive measures and immediate post-injury actions. Attitudes towards NSIs varied, with some prioritizing patient care over healthcare worker safety. However, there was strong support for the immediate reporting of sharp injuries and belief in the preventability of NSIs.

Study’s Excerpt/Novelty This study reveals a significant Epstein-Barr Virus (EBV) prevalence among pregnant women attending Cottage Hospital in Ilorin, with 95.69% of participants testing positive for anti-EBV IgG antibodies. Notably, the highest prevalence was observed among younger women, those in the first trimester, individuals from polygamous families, and those with lower educational levels. These findings underscore the need for increased community awareness and improved personal hygiene practices to reduce EBV infection rates and associated congenital defects. Full Abstract Epstein-Barr Virus (EBV), a member of the Herpesvirus family, has been observed to be increasing among pregnant women, leading to congenital defects. This study aimed to determine the prevalence of EBV infection among pregnant women attending Cottage Hospital in Ilorin. A total of 45 pregnant women were tested, and questionnaires were administered to volunteer subjects after obtaining their informed consent. Approximately 5 ml of blood was aseptically collected via venous puncture from the antecubital fossa and dispensed into EDTA containers. Plasma was separated after centrifugation of the blood, and the obtained plasma was screened for anti-EBV IgG antibodies using ELISA techniques. Results revealed that 43 subjects (95.69%) tested positive for EBV, while 2 (4.4%) tested negative. Among different age groups, women aged 19-20, 26-30, and 36-40 showed a prevalence rate of 100%, with the lowest prevalence of 88.8% recorded among the 31-35 age group. Regarding the pregnancy stage, 100% was seen among first-trimester participants, while the lowest prevalence of 92.3% was noted during the third trimester. The majority of respondents were married, with those from polygamous families and single individuals showing a prevalence of 100%. Participants with primary and secondary education levels displayed the highest prevalence, while those with tertiary education had the lowest. Muslims had the highest prevalence, whereas Christians had the lowest. Moreover, regarding occupation, the unemployed, artisans, and students had the highest prevalence, while civil servants and businesswomen had the lowest prevalence. In conclusion, the results from this study highlight a notable prevalence of EBV (IgG) antibodies among pregnant women. These outcomes emphasize the necessity of raising awareness in the community about the implications of EBV infection and the Significance of maintaining proper personal hygiene to mitigate the chances of infection and spread

Virtual reality in the outpatient: reducing anxiety and fear in venous puncture

To analyze whether the use of virtual reality (VR) headsets during venipuncture can modify the perception of pain, anxiety, and fear in pediatrics. Open label, randomized clinical trial. The presence of intellectual, visual, or hearing impairment were considered exclusion criteria. Two anxiety and fear scales were administered before and after the procedure, and the Wong-Baker face pain scale at the end. The following were recorded: number of venipuncture attempts, duration of the procedure, and side effects. 78 patients were included, 38 males and a mean age of 9.63 years. In the intervention group, the mean pain value was 2.87, with a mean difference (MD) of -0.85 compared with the control one (95% confidence interval (CI) -2.02 to 0.33). There was a significant reduction in the level of anxiety and fear, with MDs of -2.59 (95%CI: -3.92 to -1.26) and -0.85 points (95%CI: -1.45 to -0.24), respectively. the use of VR headsets in venipuncture in hospital daytime care decreases the level of anxiety and fear in children and seems to reduce pain, without adverse effects. The venipuncture procedure has the same success rate and does not increase its duration.

Exploring Biomedical Waste Management Practices Among Healthcare Professionals: A Study From a Tertiary Care Teaching Hospital in Eastern India.

The generation of biomedical waste (BMW) in hospitals presents a significant hazard to both healthcare workers (HCWs) and the environment. The management of BMW is a challenge regarding inappropriate behavior among HCWs, leading to improper segregation of the BMW, which deserves attention.The indiscriminate BMW management issue in India has attracted the attention of the highest judicial bodies. The rise in the incidence of needle stick injuries is a severe threat to waste handlers and is mainly due to improper segregation practices. This study aimed to identify the challenges in BMW management in the institute and develop a strategy to improve the knowledge and practices of healthcare professionals (HCPs) in BMW management. A process-based intervention was developed and implemented that involved facility inspection rounds, focused group discussions with HCWs, preparation of information, education, and communication (IEC) materials, signage, staff training, and improved infrastructure and supplies for waste collection. A questionnaire-based evaluation of the staff's knowledge of BMW management was conducted, and the impact of the intervention was assessed from the hospital infection control audit reports. Multiple reasons for poor compliance with BMW segregation practices were identified, and it improved from 57% to 91% with interventions. A significant difference was noted in the knowledge level of staff before and after the interventions.Post-intervention score was highest among the nurses (98.5%), followed by sanitation staff (92.7%), doctors (89.25%), and paramedics (81.7%). Incorrect segregation practices of BMW and incidents of occupational exposure to blood and body fluids are reduced with interventions in the study. Robust supply chain management with regular training of staff is vital to ensure compliance in BMW management.

Ultrasound-Guided Subclavian Vein Catheterization: Contrasting Supraclavicular and Infraclavicular Approaches for Enhanced Procedural Precision.

Background Ultrasound-guided subclavian vein catheterization is crucial for central venous access, but the choice between the supraclavicular and infraclavicular approaches lacks comprehensive comparison. This study addresses this gap by conducting a prospective observational analysis of both techniques. The supraclavicular method accesses the vein from above the clavicle while the infraclavicular targets it below. Our model-driven approach aims to elucidate the procedural nuances, success rates, and complications associated with each method. The findings intend to equip clinicians with evidence-based insights, facilitating informed decision-making for improved procedural outcomes in ultrasound-guided subclavian vein catheterization. Aim and objective This study aims to comprehensively compare the supraclavicular and infraclavicular approaches in ultrasound-guided subclavian vein catheterization, evaluating the procedural minutiae, potential advantages, and challenges associated with each technique. Employing a prospective observational methodology, our objective is to provide evidence-based insights for approaches in ultrasound-guided subclavian vein catheterization, evaluating procedural nuances, success rates, and complications during the procedure. Methods In this prospective investigation, 276 patients aged between 20 and 55 years were randomly assigned to two groups: 143 patients in the supraclavicular group and 133 patients in the infraclavicular group. Specifically, patients admitted for elective surgery necessitating postoperative ICU care were considered. The study assessed various variables, including success rate, time required for venous visualization, venous puncture, catheterization, total procedure duration, and incidence of mechanical complications, to facilitate group comparisons. Results The mean procedural time was shorter in the supraclavicular group compared to the infraclavicular group, with durations of 2 minutes and 2 seconds versus 3 minutes and 40 seconds, respectively (95% CI). This difference was statistically significant. Similarly, the mean durations for venous visualization, venous puncture, and venous catheterization were also shorter in the supraclavicular group, and these differences were statistically significant. Both groups achieved a 100% success rate, with the first attempt success rate being higher in the supraclavicular subclavian vein group. Conclusion The findings of this study demonstrate a statistically significant advantage in favor of the supraclavicular approach for ultrasound-guided subclavian vein catheterization. The shorter mean procedural time, as well as durations for venous visualization, puncture, and catheterization, emphasize the efficiency of the supraclavicular technique. The consistently achieved 100% success rate, coupled with a higher first-attempt success rate, further underscores the proficiency of the supraclavicular subclavian vein group. These results collectively suggest that the supraclavicular approach is not only time-efficient but also superior in terms of successful central line placement, making it a promising choice for both emergency and critical care settings.

The multicenter ablate-by-LAW study: personalized paroxysmal atrial fibrillation ablation according to the local left atrial wall thickness

Abstract Background Personalized radiofrequency (RF) catheter ablation for paroxysmal atrial fibrillation (PAF), tailoring the ablation index (AI) to the local left atrial wall thickness (LAWT), has proven to be an efficient procedure with high arrhythmia-free survival rates. However, to date, only monocentric experiences have been reported in the literature. Purpose The present study sought to report a multicenter experience in order to assess the safety, efficacy, and efficiency, of a LAWT-guided personalized pulmonary vein isolation (PVI) approach for PAF ablation (ClinicalTrials.gov, NCT04218604). Methods We conducted an international multicenter prospective study at five tertiary hospitals (two in Spain, one in Italy, one in Germany, and one in the United States). Consecutive patients referred for first-time RF catheter ablation of PAF were prospectively enrolled from November 2020 to September 2022. In all patients a three-dimensional map of LAWT were obtained from preprocedural multidetector computed tomography (MDCT)-derived data postprocessing. LAWT was categorized into 1 mm layers and AI was titrated according to the LAWT. All procedures were performed under general anesthesia, utilizing high-rate low-tidal volume (HR-LTV) ventilation (Figure 1). All antiarrhythmic drugs were discontinued following the 3-month blanking period. The primary endpoint was freedom from any documented sustained atrial arrhythmia at 12-month follow-up, regardless of symptoms. Results One hundred and nine patients (60.1±9.4 years, 64.2% male) were prospectively enrolled. The mean LA diameter was 38.7±5.8 mm and the mean left ventricular ejection fraction was 60.7±4.7%. The median procedure time was 61.7 minutes (IQR 48.4–83.8), and the median RF application time was 13.9 minutes (IQR 12.3–16.8). The mean number of VisiTags was 63.2 ± 18. First-pass PVI was achieved in the 83.5% of patients. The median fluoroscopy time was 61.5 seconds (IQR 22.5–197.5). In 94 (86.2%) patients, ablation was performed with a single femoral venous puncture. At 12-month follow-up, the rate of freedom from any documented atrial arrhythmia was 93.4% (Figure 1). Two (1.8%) patients died during follow-up, one from unknown cause three months after the procedure, and another from complications following multiple trauma after falling from a ladder. One patient (0.9%) developed femoral artery pseudoaneurysm, with no other serious procedure-related complications. Conclusion The Ablate-by-LAW multicenter study proved that a personalized PAF ablation protocol, tailoring the AI to the local LAWT is highly efficient and achieved a high acute first-pass PVI rates. The study reported a high 12-month survival-free from any documented sustained atrial arrhythmias, exceeding 90%, and an exceptionally low incidence of serious procedure-related complications.
