Tsukamurella Bacteremia in a Surgical Patient: Case Report and Review of the Literature.

Background: Tsukamurella species were first isolated in 1941. Since then, 48 cases of Tsukamurella bacteremia have been reported, a majority of which were immunosuppressed patients with central venous catheters.A case is described and previous cases of Tsukamurella bacteremia are reviewed. Patients and Methods: A 70-year-old total parenteral nutrition (TPN)-dependent female with recurrent enterocutaneous fistula (ECF), developed leukocytosis one week after a challenging ECF takedown. After starting broad-spectrum antibiotic agents, undergoing percutaneous drainage of intra-abdominal abscess, and subsequent repositioning of the drain, her leukocytosis resolved. Blood and peripherally inserted central catheter (PICC) cultures grew Tsukamurella spp. The patient was discharged to home with 14 days of daily 2 g ceftriaxone, with resolution of bacteremia. Conclusions: Tsukamurella spp. are a rare opportunistic pathogen predominantly affecting immunocompromised patients, with central venous catheters present in most cases. However, there have been few reported cases in immunocompetent individuals with predisposing conditions such as end-stage renal disease and uncontrolled diabetes mellitus.

Comparing conventional and modified Seldinger techniques using a micro-insertion kit for PICC placement in neonates: a retrospective cohort study

ObjectiveThis study aims to assess the comparative effectiveness of a conventional splitting needle or a peelable cannula vs. the modified Seldinger technique (MST) by utilizing a dedicated micro-insertion kit across various clinically significant metrics, including insertion success, complications, and catheter-related infections.MethodsWe conducted a retrospective observational cohort study using an anonymized data set spanning 3 years (2017–2019) in a large tertiary-level neonatal intensive care unit in Qatar.ResultsA total of 1,445 peripherally inserted central catheter (PICC) insertion procedures were included in the analysis, of which 1,285 (89%) were successful. The primary indication for insertion was mainly determined by the planned therapy duration, with the saphenous vein being the most frequently selected blood vessel. The patients exposed to MST were generally younger (7 ± 15 days vs. 11 ± 26 days), but exhibited similar mean weights and gestational ages. Although not statistically significant, the MST demonstrated slightly higher overall and first-attempt insertion success rates compared to conventional methods (91 vs. 88%). However, patients undergoing conventional insertion techniques experienced a greater incidence of catheter-related complications (p < 0.001). There were 39 cases of catheter-related bloodstream infections (CLABSI) in the conventional group (3.45/1,000 catheter days) and eight cases in the MST group (1.06/1,000 catheter days), indicating a statistically significant difference (p < 0.001). Throughout the study period, there was a noticeable shift toward the utilization of the MST kit for PICC insertions.ConclusionThe study underscores the viability of MST facilitated by an all-in-one micro kit for neonatal PICC insertion. Utilized by adept and trained inserters, this approach is associated with improved first-attempt success rates, decreased catheter-related complications, and fewer incidences of CLABSI. However, while these findings are promising, it is imperative to recognize potential confounding factors. Therefore, additional prospective multicenter studies are recommended to substantiate these results and ascertain the comprehensive benefits of employing the all-in-one kit.

Adverse Events from Fluoroscopic versus Portable Placement of PICCs and CVCs in Pediatric Patients.

To evaluate the outcomes of fluoroscopic versus portable placement of peripherally inserted central catheters (PICCs) and central venous catheters (CVCs) in pediatric patients. This is a single-center, retrospective review of 346 upper-extremity PICCs (286 fluoroscopic, 60 portable), mean age = 9.83 ± 5.58 years, 49.1% female; and 138 tunneled femoral CVCs (56 fluoroscopic, 82 portable), mean age = .23 ± .36 years, 57.0% female. Portable placements used mobile plain-film radiography. All lines were placed by board-certified interventional radiologists. Fluoroscopic PICC versus portable PICC placements had a lower procedure time (43.9 vs. 57.9 minutes, P<.001); radiation dosage (342 vs. 590 mGy.cm2, P<.001); incidence of technical failure (0 vs. 3.3%, P=.029); incidence of catheter malfunction (1.7% vs. 12.1%, P<.001). Fluoroscopic CVC versus portable CVC placements had a lower procedure time (42.6 vs 54.8 minutes, P<.001); and radiation dosage (63.8 vs 405 mGy.cm2, P<.001). No technical failures were found in either CVC groups and the difference was non-significant for catheter malfunction (0 vs 7.3%, P=.081). Fluoroscopic placements of PICCs and CVCs had a lower incidence rate of central line-associated bloodstream infection (CLABSI) compared to portable placements (.71 vs 2.22 cases per 1000 line-day, P=.046). Overall, fluoroscopic placements of PICCs and CVCs had fewer adverse events compared to portable placements (3.2% vs 14.8%, P<.001). Portable procedure was the only significant factor associated with adverse events (OR, 33.77 (4.56-757.01)). Fluoroscopic placements of PICCs and CVCs are associated with lower procedure time, radiation dose, and risk of adverse events compared to portable placements in pediatric patients.

Complications after peripherally inserted central catheter versus central venous catheter implantation in intensive care unit: propensity score analysis using a nationwide database

ABSTRACT Background It remains unclear whether peripherally inserted central catheters (PICCs) are superior to central venous catheters (CVCs); therefore, we compared post-implantation complications between CVC and PICC groups. Research design and methods Patients who received CVCs or PICCs between April 2010 and March 2018 were identified from the Diagnosis Procedure Combination database, a national inpatient database in Japan. The outcomes of interest included catheter infection, pulmonary embolism, deep vein thrombosis, and phlebitis. Propensity score overlap weighting was used to balance patient backgrounds. Outcomes were compared using logistic regression analyses. Results We identified 164,185 eligible patients, including 161,605 (98.4%) and 2,580 (1.6%) in the CVC and PICC groups, respectively. The PICC group was more likely to have overall complications (odds ratio [OR], 1.70; 95% confidence interval [CI], 1.32–2.19), pulmonary embolism (OR, 2.32; 95% CI, 1.38–3.89), deep vein thrombosis (OR, 1.86; 95% CI, 1.16–2.99), and phlebitis (OR, 1.72; 95% CI, 1.27–2.32) than the CVC group. There was no significant intergroup difference in catheter infection (OR, 1.09; 95% CI, 0.39–3.04). Conclusions Patients with PICCs had a significantly greater incidence of complications than did those with CVCs. Further research is necessary to explore the factors contributing to these complications.

ChatGPT may free time needed by the interventional radiologist for administration / documentation

Motive: Documentation and administration, unpleasant necessities, take a substantial part of the working time in the subspecialty of interventional radiology. With increasing future demand for clinical radiology predicted, time savings from use of text drafting technologies could be a valuable contribution towards our field. Method: Three cases of peripherally inserted central catheter (PICC) line insertion were defined for the present study. The current version of ChatGPT was tasked with drafting reports, following the Radiological Society of North America (RSNA) template. Key results: Score card evaluation by human radiologists indicates that time savings in documentation / administration can be expected without loss of quality from using ChatGPT. Further, automatically generated texts were not assessed to be clearly identifiable as AI-produced. Conclusions: Patients, doctors, and hospital administrators would welcome a reduction of the time that interventional radiologists need for documentation and administration these days. If AI-tools as tested in the present study are brought into clinical application, questions about trust into those systems eg with regard to medical complications will have to be addressed.

Ultrasound vs. standard radiography to determine peripherally-inserted central catheter tip location

Background The use of a peripherally-inserted central catheter (PICC) has increased in preterm neonates to facilitate the administration of total parenteral nutrition. Standard radiography (thoracoabdominal X-ray) is the gold standard for determining the position of the PICC tip. However, radiography is not always accurate, influenced by the position of the extremities and anatomic variations, time-consuming procedural process, involves radiation, and is costly. Ultrasonography (USG) may serve as an easier, safer, less costly, and more real-time alternative in the neonatal intensive care unit (NICU) patients. Objective To assess the accuracy of USG use in determining PICC tip position compared to that of standard radiography. Methods This diagnostic study was conducted in the NICU at Dr. Cipto Mangunkusumo Hospital, Jakarta. The PICCs were placed using standard NICU procedure, then the tip position was evaluated using the USG immediately before standard radiography was performed. A 2x2 table was constructed to compare the diagnostic accuracy of the two modalities. Results A total of 29 neonates were included in our study. Subjects’ mean gestational age and weight were 31.7 weeks and 1,618.9 g respectively. Concordance of PICC tip positioning between standard radiography and USG occurred in 27 neonates (93.1%). USG had 88.89% sensitivity, 95% specificity, and 93.1% diagnostic accuracy. Conclusion USG has excellent diagnostic accuracy for confirmation of the PICC tip position.

The Impact of Provider Experience on Central 
Line Malposition

Background: Central lines are frequently used in the Neonatal Intensive Care Unit (NICU). Incorrectly positioned central lines are associated with increased complications. Central line malposition has been related to prematurity, catheter size, and small-for-gestation-age status. The impact of provider experience on proper central line positioning has not been established. Methods: In this retrospective cohort study, neonates had central lines placed within the first 10 days of life. Central lines included umbilical artery catheters (UAC), umbilical vein catheters (UVC), and peripherally inserted central catheters (PICC). Central line malposition was confirmed with thoracoabdominal radiography. Different providers with various months/years of experience were coded. Logistic regression models were fit to adjust for potential confounders of the association of years of experience with line malposition. Results: Between 2019 and 2021, 301 neonates had 616 central lines. 66% (405/616) of all central lines were malpositioned. The median years of providers’ experience who placed malpositioned and properly positioned lines were 1.93 (interquartile range [IQR]: 1.03–5.48) years and 2.17 (IQR: 1.38–4.85) years, respectively ( P = .78). The distribution of malposition lines was UVC 49% (199/405), UAC 20.5% (83/405), and PICC 30.5% (123/405). Only UVC was significantly associated with malposition ( P = .002). Conclusions: Malposition of central lines frequently occurred in the NICU and was associated with UVC placement, irrespective of the provider’s experience who accessed it. Anatomical variations in neonates with different gestational ages and birth weights may mean that current methods to estimate insertion depth can be misleading. Future interventions should involve novel techniques of confirming real-time positioning during insertion rather than focusing on placement calculations.

Case series of peripherally inserted central catheter insertion in young children: A new approach to the axillary vein.

We have developed a new approach for peripherally inserted central catheter (PICC) insertion that we think has several advantages, including ease of insertion, access to a larger vein and patient comfort. In this case series report, the first 19 cases were audited. All PICCs were inserted without complications; 17 on the first attempt. We conclude that the novel approach to the axillary vein for PICC insertion is feasible and appears to be safe when performed by an experienced operator.

Risk factors and prediction model construction for peripherally inserted central catheter-related infections

ObjectiveTo establish a predictive modeling for the risk of bloodstream infection associated with peripherally inserted central catheter (PICC). MethodsPatients receiving PICC treatment in Shenzhen People's Hospital from June 2020 to December 2020 were retrospectively enrolled and divided into the infection group and the non-infection group according to the presence and absence of PICC-related infections. Then, relevant clinical information of patients was collected and the predictors of PICC-related infection were screened by the least absolute shrinkage and selection operator regression (LASSO) model. Besides, multivariate logistic regression was used to analyze the influencing factors of PICC-related infection, A nomogram was constructed based on the results of the multivariate analysis. Ultimately, a receiver operating characteristic (ROC) curve was plotted to analyze the application value of influencing factors to predict PICC-related infections. ResultsA total of 505 patients were included, including 75 patients with PICC-related infections (14.85%). The main pathogen was gram-positive cocci. The predictors screened by LASSO included age >60 years, catheter movement, catheter maintenance cycle, insertion technique, immune function, complications, and body temperature ≥37.2 °C before PICC placement. Multivariate logistic regression analysis showed that independent risk factors of infections related to PICC included age >60 years [odds ratio (OR) = 1.722; 95% confidence interval (CI) = 1.312–3.579; P = 0.006], catheter movement (OR = 1.313; 95% CI = 1.119–3.240; P = 0.014), catheter maintenance cycle >7 days (OR = 2.199; 95% CI = 1.677–4.653; P = 0.000), direct insertion (OR = 1.036; 95% CI = 1.019–2.743; P = 0.000), poor immune function (OR = 2.322; 95% CI = 2.012–4.579; P = 0.000), complications (OR = 1.611; 95% CI = 1.133–3.454; P = 0.019), and body temperature ≥37.2 °C before PICC placement (OR = 1.713; 95% CI = 1.172–3.654; P = 0.012). Besides, the area under the ROC curve was 0.889. ConclusionPICC-related infections are associated with factors such as age >60 years, catheter movement, catheter maintenance cycle, insertion technique, immune function, complications, and body temperature ≥37.2 °C before PICC placement. Additionally, the LASSO model is moderately predictive for predicting the occurrence of PICC-related infections.

[Mid-term analysis of prospective cohort study of rivaroxaban in preventing CRT in breast cancer].

Objective: To explore the efficacy and safety of Rivaroxaban in preventing catheter related thrombosis (CRT) in patients with breast cancer who are undergoing central venous catheter chemotherapy, and provide basis for making standardized prevention and treatment strategies. Methods: In this research, a prospective cohort study was adopted, and breast cancer patients who received central venous catheter chemotherapy in Sanhuan Cancer Hospital during September 2020 to March 2022 were selected as a treatment group to take the rivaroxaban anticoagulation therapy with 10 mg.po.qd for one month. The control group got no preventive anticoagulation therapy. Vascular ultrasound examination was taken to confirm the occurrence of CRT, and a chi-square test was done for comparison the disparity between the groups. Logistic regression was applied to analyze the univariate and multivariate factors for the formation of CRT. Results: In the research, a total of 235 patients were selected, and there were a total of 19 035 days of catheterization with 81 days of catheterization on average. While in the control group, the incidence of CRT was 28.0% (33/118), the incidence of CRT in the treatment group was 20.5% (24/117), the difference was no significant (P=0.183). Subgroup analysis results showed that the peripherally inserted central catheter (PICC) was performed in 165 cases with the CRT incidence of 18.2% (30/165) and thrombosis was mostly seen around axillary vein, accounting for 63.3%. Subclavian vein catheterization was performed in 63 cases with the CRT incidence of 39.7% (25/63), and thrombosis was mostly seen around subclavian vein, accounting for 88.0% (22/25). Implantable venous access port was implanted in 7 cases around subclavian vein and internal jugular vein with the CRT incidence of 28.6% (2/7). The patients who developed CRT within 30 days after catheterization accounted for 54.4% (31/57), 22.8% (13/57) in a period during 30 days and 60 days) and 22.8% (13/57) in a period during 60 days and 180 days). The diagnosed CRT patients had been treated with rivaroxaban 15 mg.bid.po for 3 months. During the 3 months, 100.0% of the thrombosis waned, 71.9% (41/57) of the thrombosis waned within 30 days, 19.3% (11/57) in a period during 30 and 60days and 8.8% (5/57) in a period during 60 days and 90 days. Univariate and multivariate analysis indicated that the risk of CRT in subclavian vein catheterization was higher than that in PICC, respectively (OR=2.898, 95% CI:1.386-6.056 P=0.005), and the type of catheterization was an independent factor for the formation of thrombosis. Safety analysis result showed that in the prevention of CRT, rivaroxaban treatment did not induce drug-related bleeding, liver function damage, bone marrow suppression or any other side effects. While CRT diagnosed patients were treated with anticoagulation, they kept the central venous catheter, and the infusion was smooth. These patients all finished the anti-tumor treatment as planned, and no abnormalities like new thrombosis or pulmonary embolism were observed. Conclusions: In the mid-term analysis, the proportion of Rivaroxaban in preventing anticoagulant CRT decreases, but it don't reach statistical significance. The sample size should be further increased for observation. Rivaroxaban is proved effective and very safe in the treatment of CRT, and does not affect the concurrent chemotherapy. Medical personnel should carry out the policy of "early prevention, early detection and early treatment" for CRT so as to improve the patients' quality of life.

Analysis and risk factors of deep vein catheterization-related bloodstream infections in neonates.

To investigate the incidence, risk factors, and pathogenic characteristics of catheter-related bloodstream infection caused by peripherally inserted central venous catheter in neonates, and to provide references for reducing the infection rate of peripherally inserted central venous catheter. The clinical data of 680 neonates who underwent peripherally inserted central catheter (PICC) in the neonatal intensive care unit from June 2020 to June 2023 were retrospectively analyzed. The risk factors and independent risk factors of catheter-related bloodstream infection caused by PICC were determined by univariate and multivariate analysis, respectively. Catheter-related bloodstream infection occurred in 38 of 680 neonates who underwent PICC. The infection rate was 4.74%. The proportions of fungi, gram-positive bacteria, and gram-negative bacteria were 42.11%, 36.84%, and 21.05%, respectively. Candida parapsilosis was the main fungus (18.42%), coagulase negative Staphylococcus was the main gram-positive bacteria (23.68%), and Klebsiella pneumoniae and Escherichia coli were the main gram-negative bacteria (7.89%). Univariate analysis showed that gestational age ≤32 weeks, birth weight ≤1500 g, congenital diseases, nutritional support, catheterization time, 5-minute APGAR score ≤7, and neonatal respiratory distress syndrome were associated with catheter-related bloodstream infection caused by PICC. Multivariate analysis showed that premature delivery, low birth weight, parenteral nutrition, long catheterization time, and 5-minute APGAR score ≤7 were associated with catheter-related bloodstream infection caused by PICC. Among the pathogens detected, there were 6 cases of K pneumoniae, 5 cases of coagulase negative staphylococci, and 2 cases of fungi. Low birth weight, premature delivery, off-site nutrition, long catheterization time, and 5-minute APGAR score ≤7 are independent risk factors for catheter-related bloodstream infection in neonates with peripherally inserted central venous catheters. The pathogenic bacteria are fungi and multidrug-resistant bacteria.

Trends in the prevalence and risk factors for peripherally inserted central catheter-related complications in cancer patients from 2016 to 2022: a multicenter study.

To identify the trends in the prevalence of peripherally inserted central catheter (PICC) related complications in cancer patients and explore the risk factors for complications and occurrence speed. A total of 3573 cancer patients with PICC were recruited at 17 hospitals from 2016 to 2022. Logistic and COX regression were performed to identify influencing factors of PICC-related complications and incidence speed, respectively. The proportion of symptomatic PICC-related thrombosis, phlebitis, and infections reported had decreased from 59.1% (in 2017), 11.9% (in 2016), and 11.1% (in 2016) to 15.3% (in 2022), 2.9% (in 2022), and 7.4% (in 2022), and adhesive-related skin injuries and bleeding/oozing reported had increased from 4.8% (in 2016) and 0.0% (in 2016) to 45.5% (in 2022) and 3.4% (in 2022), respectively. Catheter occlusion showed a trend of first increasing and then decreasing from 2.4 (in 2016) to 12.0 (in 2020) to 5.8% (in 2022). Logistic regression showed that hospital level, nature, the patient's gender, age, diagnosis, history of deep vein catheterization, chemotherapy drug administration, and type of PICC were influencing factors of complications. COX regression showed that the patient's gender, age, diagnosis, history of deep vein thrombosis and thrombophlebitis, history of deep vein catheterization, chemotherapy drug administration, type of PICC, type of connector, and StatLock used for fixation were influencing factors of incidence speed. The composition ratios of PICC-related complications in cancer patients in China have changed in recent years. Chemotherapy drug administration was a significant risk factor accelerating the occurrence of complications. Maintenance factors had the maximum weight on the COX model, followed by patient factors. It is suggested that patients with high-risk factors be closely monitored and proper maintenance be performed to prevent and delay the occurrence of PICC-related complications.

Incidence of Catheter-Associated Bloodstream Infections in Stem Cell Recipients-Should We Be "PICCy"?

The management of patients undergoing HSCT requires a multipurpose central venous catheter. Peripheral catheters (PCs), such as peripherally inserted central catheters (PICCs) and MidLine catheters (MLCs), appear to be adequate vascular catheters to be used for stem cell infusion, although their utilization in this indication is not yet common. We analyzed the infectious complications such as blood stream infection (BSI), febrile neutropenia (FN) and central line-associated bloodstream infection (CLBSI) in patients undergoing stem cell infusion through PC and conventionally inserted central catchers (CICCs), and evaluated their impacts on transplantation outcomes. Our results reveal no statistically significant differences between different types of catheter in terms of FN, BSI and CLABSI. Moreover, transplantation outcomes were comparable between the groups. Interestingly, according to our data, there were no differences in terms of abovementioned infectious complications between individuals who received antibiotic prophylaxis and those who did not. Our study has shown that infection complications are independent of the intravenous device and antibiotic prophylaxis. Considering that PCs are not associated with life-threatening complications, they should be considered more frequently in the stem cell transplantation setting.

A Comparison of In Vitro Measurement and Ultrasound for Peripherally Inserted Central Catheter Placement in Premature Infants: A Before-and-After Self-Controlled Prospective Study.

Background This study aimed to investigate the effectiveness of ultrasonography (US) and in vitro measurement (IVM) methods in localizing peripherally inserted central catheters (PICCs) in premature infants and analyze the relevant factors affecting the accuracy of IVM. Methodology The study employs a prospective before-and-after self-controlled clinical trial design. A total of 210 premature infants who underwent PICC catheterization were compared. We assessed the rate of catheter tip placement, consistency, and stability and analyzed the relevant factors. Results The study enrolled a total of 202 premature infants after eight infants dropped out. The one-time positioning rates of the PICC catheter tip using US and IVM were 100% and 73.8%, respectively. Concerning IVM, 53 (26.2%) patients did not reach the optimal position, with 24 (11.8%) patients having a shallow position and 29 (14.3%) having a deep position. The consistency of the two methods was 0.782 (p < 0.05). The degree of dispersion of US was 0.2 (0.0-0.4) cm, which was significantly smaller than IVM at 1.5 (0.0-1.8) cm. Gestational age less than 32 weeks (odds ratio (OR) = 6.64, 95% confidence interval (CI) = 1.43-30.81), weight less than 1,500 g (OR = 5.85, 95% CI = 2.11-16.20), body length less than 40 cm (OR = 15.36, 95% CI = 4.47-52.72), mechanical ventilation (OR = 5.13, 95% CI = 1.77-14.83), abdominal distension (OR = 78.18, 95% CI = 10.62-575.22), and bloating (OR = 8.81, 95% CI = 1.42-47.00) were risk factors that affected the accuracy of IVM. Conclusions Gestational age, weight, length, mechanical ventilation, abdominal distension, and swelling can lead to deviations with IVM. US can directly view the tip of the catheter, which is more accurate. Additionally, it is recommended to reduce the length of the catheter by 1.3 cm when using IVM to achieve the best-estimated placement length.

Effect of intracavitary electrocardiographic localization on the success rate and complications of PICC in infants.

Peripherally inserted central catheter (PICC) is widely used in chemotherapy of children with malignant tumors because of its safe operation and long indwelling time. To investigate the effect of intracavitary electroencephalogram (CEEG) localization technique on the success rate and complications of PICC in infants. A total of 180 children with PICC catheterization and maintenance at Shijiazhuang People's Hospital First Hospital from January 2017 to January 2020 were selected and divided into control group (n= 90 cases) and observation group (n= 90 cases). The control group observed the tip position of the fixed catheter through X-ray film and adjusted the catheter until its tip was located in the superior vena cava. The observation group used intracavitary electrocardiogram positioning technology. Comparison of the effects of two groups on the success rate and complications of PICC puncture in infants and young children. The success rate of one puncture in the observation group was significantly higher than that in the control group (P< 0.05). Within one month of catheterization, 13 cases had complications, with an incidence rate of 16.00% lower than the control group's 34.00% (27/80) (P< 0.05). The screening test results showed that the specificity, sensitivity, Youden index, accuracy, kappa coefficient, positive and negative predictive value were 88.89%, 97.56%, 0.86, 96.00%, 0.86, 0.86, respectively. The measured values were 97.56% and 88.89% respectively, and the cost and time of localization were lower than those of X-ray. The technique of intracavitary electrogram can be more accurate for infants to place the tip of central venous catheter through peripheral vein, which can effectively improve the success rate of one puncture with low cost, and has high reliability, accuracy and practicability, which is safe and effective.

The burden of skin and soft tissue, bone and joint infections in an Australian cohort of people who inject drugs

IntroductionThere are currently limited data regarding the clinical and economic significance of skin and soft tissue infections (SSTI) and bone and joint infections in Australian people who inject drugs (PWID).MethodsRetrospective cohort study in adult PWID admitted to Monash Health, a large heath care network with six hospitals in Victoria, Australia. Inpatients were identified using administrative datasets and International Classification of Disease (ICD-10) coding for specific infection-related conditions. Cost analysis was based on mean ward, intensive care and hospital-in-the-home (HITH) lengths of stay. Spinal infections and endocarditis were excluded as part of previous studies.ResultsA total of 185 PWID (61 female, 124 male, median age 37) meeting the study criteria were admitted to Monash Health between January 2010 and January 2021. Admitting diagnoses included 78 skin abscesses, 80 cellulitis, 17 septic arthritis, 4 osteomyelitis, 3 thrombophlebitis and 1 each of necrotising fasciitis, vasculitis and myositis. Pain (87.5%) and swelling (75.1%) were the most common presenting complaints. Opioids (67.4%) and methamphetamine (37.5%) were the most common primary drugs injected. Almost half (46.5%) of patients had concurrent active hepatitis C (HCV) infection on admission. Hepatitis B (HBV) and Human Immunodeficiency Virus (HIV) were uncommon. The most significant causative organism was methicillin-susceptible Staphylococcus aureus (24.9%). In 40.0% (74/185) no organism was identified. Patients required a median acute hospital stay of 5 days (2–51 days). There were 15 patients admitted to the intensive care unit (ICU) with median duration 2 days. PICC line insertion for antibiotics was required in 16.8% of patients, while 51.4% required surgical intervention. Median duration of both oral and IV antibiotic therapy was 11 days. Almost half (48.6%) of patients were enrolled in an opioid maintenance program on discharge. Average estimated expenditure was AUD $16, 528 per admission.ConclusionSkin and soft tissue and joint infections are a major cause of morbidity for PWID. Admission to hospital provides opportunistic involvement of addiction specialty services.

The Outcomes of Peripherally Inserted Central Catheter (PICC) Insertion in Pediatric Patients at Siriraj Hospital

Objective: Peripherally Inserted Central Catheters (PICC) are widely used for intermediate to long term venous access. Venipunctures and catheterizations in pediatric patients can be challenging and traumatizing to children’s veins due to frequent and painful needle sticks. This study aims to demonstrate the outcomes of PICC insertion and management in pediatric patients by the Anesthesia Line Service Team (ALiST) at Siriraj Hospital. Materials and Methods: This is a retrospective, descriptive study collecting data from January 2018 to December 2021. The inclusion criteria were pediatric patients aged 15 years and under, body weight equal to or exceeding 5 kg with no history of previous complicated central venous accesses. The primary outcome is the success rate of insertion.  Results: 124 PICCs were inserted in pediatric patients. The median age of patients was 5.0 years, with a median height of 107.8 cm, and a median weight of 10.0 kg. The successful insertion rate was 96.92%, and all insertions were inserted using ultrasound-guided technique, with or without fluoroscopy. No acute complications were noted during insertion. Most patients received either intravenous sedation (39.5%) or general anesthesia (26.6%) during the procedure. The mean duration of catheter indwelling was 66.48 days. Reasons for removal of PICC included completion of therapy and patient demise (70.97%), catheter malformation (8.06%), accidental removal (4.03%), infection (8.06%), and patient non-adherence (1.61%). Conclusion: Our research demonstrates a notably high rate of successful PICC placement among pediatric patients, with data indicating a minimal occurrence of complications and an extended duration of catheter usage.

Virtual Reality for the Management of Pain and Anxiety for IR Procedures: A Prospective, Randomized, Pilot Study on Digital Sedation

PurposeTo assess the analgesic and anxiolytic effects of virtual reality (VR) augmentation in patients undergoing peripherally inserted central catheter (PICC) placement or fine-needle aspiration thyroid biopsy. Materials and MethodsThis is a prospective, single-center randomized controlled trial with 107 patients enrolled. Patients were randomly assigned to receive standard of care (SOC) or SOC+VR during PICC or thyroid biopsy procedures. Pain and anxiety were individually measured using the visual analog scale (VAS) before and after the procedure. Vital signs including heart rate and systolic and diastolic blood pressure were also recorded. One-way analysis of variance test and Games–Howell post hoc analysis were used to assess effect size and statistical significance between SOC and SOC+VR measures. ResultsThe PICC cohort consisted of 59 patients (33 in SOC+VR and 26 in SOC), with a median age of 53.1 years (interquartile range [IQR], 38.3–62.7 years). The thyroid biopsy cohort consisted of 48 patients (26 in SOC+VR and 22 in SOC), with a median age of 60.1 years (IQR, 49.0–67.2 years). One-way analysis of individuals undergoing thyroid biopsies with adjunctive VR revealed an effect size of −1.74 points (SE ± 0.71; P = .02) on VAS pain scale when compared with SOC. Analysis of individuals undergoing PICC placements revealed an effect size of −1.60 points (SE ± 0.81; P = .05) on VAS anxiety when compared with SOC. ConclusionsVR as a nonpharmacologic adjunct reduced some procedure-related pain and anxiety without increasing the procedural duration.

Incidence and clinical progression of asymptomatic peripherally inserted central catheter–related thrombosis in solid neoplasm patients: ultrasound insights from a prospective cohort study

BackgroundManaging central venous catheters in patients with neoplasms is challenging, and peripherally inserted central catheter (PICC)-port has emerged as a promising option for safety and efficacy. However, understanding the clinical progression of catheter-related thrombosis (CRT) in cancer patients with central venous catheters remains limited, especially in certain neoplasm types associated with a higher risk of venous thrombosis. MethodsIn this prospective cohort study of 120 patients with solid neoplasms receiving chemotherapy, we investigated the incidence of isolated upper-extremity superficial vein thrombosis, upper-extremity deep vein thrombosis, and fibrin sheath formation through ultrasound follow-up at 30 and 90 days after catheter insertion. We analyzed risk factors associated with CRT and compared incidence rates between PICC-PORT and traditional PICC. ResultsAmong the cohort, 69 patients (57.5%) had high-risk thromboembolic neoplasm, and 31 cases (25.8%) of CRT were observed, mostly within 30 days, with only 7 cases (22.6%) showing symptoms. Traditional PICC use (odds ratio, 5.86; 95% CI, 1.14-30) and high-risk thromboembolic neoplasm (odds ratio, 4.46; 95% CI, 1.26-15.81) were identified as independent risk factors for CRT. ConclusionThe majority of CRT present asymptomatically within the first 30 days of venous catheter insertion in patients with solid neoplasms. Ultrasound follow-up is valuable for detecting asymptomatic CRT. The risk of CRT was lower with PICC-PORT than with PICC. Additionally, the risk of CRT was found to be higher in patients with high-risk thromboembolic neoplasms. It is crucial for larger studies to confirm the utility of treating asymptomatic thromboses and isolated superficial thrombosis.

Nursing perceptions and practices in relation to adverse events related to peripherally inserted central catheters in neonates: A mixed methods study

ObjectivesThis study aims to characterize adverse events (AEs) related to the insertion and maintenance of peripherally inserted central catheters (PICCs) in the neonatal intensive care unit, as well as to analyze the nursing team's perception of these events. MethodsAn exploratory mixed methods research that analyzed 161 medical records of newborns admitted to the Neonatal Intensive Care Unit of a public hospital in Belo Horizonte, Brazil, from January to December 2019, and conducted interviews with 17 nursing professionals from the unit. ResultsThere was an incidence of 33.5% of AEs related to PICCs in the analyzed medical records, with obstruction (33.3%), infiltration (18.5%), and catheter rupture (14.8%) being the most common. ConclusionAlthough the nursing team demonstrates theoretical knowledge about AEs, the high incidence suggests a possible gap between theory and practice, indicating the need for further investigation. The importance of continuous training and protocol updates to prevent these events is emphasized.
