An Improvised Cost-Effective Repair Technique for Management of Broken Luer Connections of Tunneled Dialysis Catheter and Salvage Existing Catheter.

Mechanical problems like break or crack in Luer connectors or hubs, clamps, and tubings are common non-infectious complications of tunneled dialysis catheters (TDC), which may lead to other TDC complications and the need to insert a new catheter. These can be tackled using TDC repair kits or spare parts, which are often not available, resulting in the insertion of a new TDC that increases morbidity, TDC-related procedures, and healthcare costs. We discuss two cases of broken Luer connections of TDC, which were managed by exchanging the broken Luer connector of TDC with the similar Luer connector of a temporary dialysis catheter. Both the repaired TDCs are thereafter functioning well. This improvised technique provides an easy, effective, long-lasting option that salvages the existing TDC and reduces the cost factor.

Central venous access devices for the delivery of systemic anticancer therapy (CAVA): a randomised controlled trial.

BACKGROUND: Hickman-type tunnelled catheters (Hickman), peripherally inserted central catheters (PICCs), and totally implanted ports (PORTs) are used to deliver systemic anticancer treatment (SACT) via a central vein. We aimed to compare complication rates and costs of the three devices to establish acceptability, clinical effectiveness, and cost-effectiveness of the devices for patients receiving SACT. METHODS: We did an open-label, multicentre, randomised controlled trial (Cancer and Venous Access [CAVA]) of three central venous access devices: PICCs versus Hickman (non-inferiority; 10% margin); PORTs versus Hickman (superiority; 15% margin); and PORTs versus PICCs (superiority; 15% margin). Adults (aged ≥18 years) receiving SACT (≥12 weeks) for solid or haematological malignancy from 18 oncology units in the UK were included. Four randomisation options were available: Hickman versus PICCs versus PORTs (2:2:1), PICCs versus Hickman (1:1), PORTs versus Hickman (1:1), and PORTs versus PICCs (1:1). Randomisation was done using a minimisation algorithm stratifying by centre, body-mass index, type of cancer, device history, and treatment mode. The primary outcome was complication rate (composite of infection, venous thrombosis, pulmonary embolus, inability to aspirate blood, mechanical failure, and other) assessed until device removal, withdrawal from study, or 1-year follow-up. This study is registered with ISRCTN, ISRCTN44504648. FINDINGS: Between Nov 8, 2013, and Feb 28, 2018, of 2714 individuals screened for eligibility, 1061 were enrolled and randomly assigned, contributing to the relevant comparison or comparisons (PICC vs Hickman n=424, 212 [50%] on PICC and 212 [50%] on Hickman; PORT vs Hickman n=556, 253 [46%] on PORT and 303 [54%] on Hickman; and PORT vs PICC n=346, 147 [42%] on PORT and 199 [58%] on PICC). Similar complication rates were observed for PICCs (110 [52%] of 212) and Hickman (103 [49%] of 212). Although the observed difference was less than 10%, non-inferiority of PICCs was not confirmed (odds ratio [OR] 1·15 [95% CI 0·78-1·71]) potentially due to inadequate power. PORTs were superior to Hickman with a complication rate of 29% (73 of 253) versus 43% (131 of 303; OR 0·54 [95% CI 0·37-0·77]). PORTs were superior to PICCs with a complication rate of 32% (47 of 147) versus 47% (93 of 199; OR 0·52 [0·33-0·83]). INTERPRETATION: For most patients receiving SACT, PORTs are more effective and safer than both Hickman and PICCs. Our findings suggest that most patients receiving SACT for solid tumours should receive a PORT within the UK National Health Service.

The Role of Health Insurance in Patient Reported Satisfaction with Bladder Management in Neurogenic Lower Urinary Tract Dysfunction Due to Spinal Cord Injury.

PURPOSE: Neurogenic lower urinary tract dysfunction is a significant source of morbidity for individuals with spinal cord injury and is managed with a range of treatment options that differ in efficacy, tolerability and cost. The effect of insurance coverage on bladder management, symptoms and quality of life is not known. We hypothesized that private insurance is associated with fewer bladder symptoms and better quality of life. MATERIALS AND METHODS: This is a cross-sectional, retrospective analysis of 1,226 surveys collected as part of the prospective Neurogenic Bladder Research Group SCI Registry. We included patients with complete insurance information, which was classified as private or public insurance. The relationship between insurance and bladder management, bladder symptoms and quality of life was modeled using multinomial logistic regression analysis. Spinal cord injury quality of life was measured by the Neurogenic Bladder Symptom Score. RESULTS: We identified 654 privately insured and 572 publicly insured individuals. The demographics of these groups differed by race, education, prevalence of chronic pain and bladder management. Publicly insured patients were more likely to be treated with indwelling catheters or spontaneous voiding and less likely to take bladder medication compared to those with private insurance. On multivariate analysis insurance type was not associated with differences in bladder symptoms (total Neurogenic Bladder Symptom Score) or in urinary quality of life. CONCLUSIONS: There is an association between insurance coverage and the type of bladder management used following spinal cord injury, as publicly insured patients are more likely to be treated with indwelling catheters. However, insurance status, controlling for bladder management, did not impact bladder symptoms or quality of life.

Cost analysis comparison between peripherally inserted central catheters and implanted chest ports in patients with cancer-A health economic evaluation of the PICCPORT trial.

BACKGROUND: A reliable central venous access device is a cornerstone in the treatment of cancer. Both peripherally inserted central catheters (PICC) and totally implanted chest ports (PORT) are commonly used for the delivery of chemotherapy. Both types of catheter can cause adverse events such as catheter-related deep venous thrombosis (CR-DVT), infection and mechanical complications. METHOD: We conducted a randomized controlled trial including 399 patients with cancer and performed a health economic evaluation investigating the cost related to PICCs and PORTs using several clinically relevant dimensions from a healthcare perspective. The cost was determined using process and cost estimate models. RESULT: PICCs are associated with a higher total cost when compared with PORTs. Combining the costs of all categories, the prize per inserted device was 824.58 EUR for PICC and 662.34 EUR for PORT. When adjusting for total catheter dwell time the price was 6.58 EUR/day for PICC and 3.01 EUR/day for PORT. The difference in CR-DVT was the main contributor to the difference in cost. The daily cost of PICC is approximately twice to that of PORT. CONCLUSION: We have demonstrated that the cost from a healthcare perspective is higher in cancer patients receiving a PICC than to those with a PORT. The difference is driven mainly by the cost related to the management of adverse events. Our findings are relevant to anaesthetists, oncologists and vascular access clinicians and should be considered when choosing vascular access device prior to chemotherapy.

Minimally invasive and inexpensive percutaneous abscess drainage using an indwelling needle cannula.

PURPOSE: Abscess is still a formidable disease and requires adequate drainage. Moreover, drainage in the head and neck area needs cosmetic care, especially in the pediatric population. In this report, we introduce our method of percutaneous abscess drainage using an indwelling needle cannula. PATIENTS AND METHODS: Ten pediatric and five adult patients with cervical and/or facial abscess treated with this drainage method were retrospectively reviewed. Using an indwelling needle cannula (18-14 G Surflow®, Terumo, Tokyo, Japan), abscesses were penetrated under ultrasonic examination. Once purulent retention was identified, the inner metal needle was removed and the outer elastic needle was left and fixed. The outer needle was connected to the tube for continuous suction drainage for large abscess. RESULTS: The primary diseases of these abscesses were cervical abscess of dental origin (5), purulent lymphadenitis (3), pyriform sinus fistula (2) and subperiosteal abscess due to mastoiditis (2), circumorbital cellulitis (1), infection of Warthin's tumor (1), and unknown origin (1). The median (range) duration of drainage was 4 days (3-9 days). Abscesses were successfully treated, and no patients required additional incision for abscess drainage. No apparent scars after drainage were observed. CONCLUSION: This technique resembles the usual venous placement of an indwelling needle cannula and is thought to be familiar to physicians. Although simple and inexpensive, this drainage is safe, effective, and minimally invasive for the treatment of abscess.

Intrathecal Baclofen Therapy in Patients With Multiple Sclerosis: Improved Outcomes and Reduced Costs Through Identification of Catheter Malfunction.

INTRODUCTION: Two patients previously implanted with intrathecal Baclofen (ITB) pumps for management of intractable spasticity due to multiple sclerosis (MS) were referred to our center for ongoing management of their spasticity. Initial evaluation of these patients revealed high levels of spasticity in the presence of ITB doses 10 times the average daily dose of our other MS patients. CLINICAL FACTS: High doses of ITB required frequent clinical visits and result in high drug and procedure costs. Both patients' daily doses were greater than 1000 mcg/day resulting in clinical visits every 1-2 months with drug and procedure costs ranging from 16 to 23 thousand dollars annually based on Medicare national average pricing for physician's office. Of the 59 MS patients receiving ITB therapy at our institution, the mean, median, and mode daily doses for ITB are 184, 115, and 159 mcg/day, respectively. The high ITB doses in these patients and poor spasticity control raised suspicion for pump/catheter malfunction and prompted immediate troubleshooting. FINDINGS: One patient's catheter was found to be disconnected from the pump and the other's catheter tip was outside the intrathecal space. In both cases, the patients were not receiving the therapy. After pump/catheter replacement, both patients received excellent clinical benefits from ITB at significantly lower daily doses. This reduction in dose resulted in decreased frequency of medication refills (twice annually) which resulted in decreased cost of care (12-19 thousand dollars savings annually per patient). DISCUSSION: These cases illustrate the need for early ITB pump troubleshooting to identify catheter problems, improve efficacy, and avoid unnecessary healthcare costs.

Taurolidine-based catheter lock regimen significantly reduces overall costs, infection, and dysfunction rates of tunneled hemodialysis catheters.

Catheter-related infections and dysfunction are the main catheter complications causing morbidity and mortality in hemodialysis patients. However, there are no consistent data for the choice of catheter lock solutions for tunneled hemodialysis lines. In this prospective, multicenter, randomized, controlled trial, two lock regimens using three commercial catheter lock solutions were compared in 106 hemodialysis patients with a newly inserted tunneled central catheter. In the taurolidine group, TauroLock™-Hep500 was used twice per week and TauroLock™-U25,000 once a week. In the citrate group, a four percent citrate solution was used after each dialysis. Both groups were compared regarding catheter-related infections, catheter dysfunction, and costs. Over a period of 15,690 catheter days, six catheter-related infections occurred in six of 52 patients in the taurolidine group, but 18 occurred in 13 of 54 patients in the citrate group, corresponding to 0.67 and 2.7 episodes of catheter-related infections per 1000 catheter days, respectively (Incidence Rate Ratio 0.25, 95% confidence interval, 0.09 to 0.63). Catheter dysfunction rates were significantly lower in the taurolidine group (18.7 vs. 44.3/1000 catheter days) and alteplase rescue significantly more frequent in the citrate group (9.8 vs. 3.8/1000 catheter days). These differences provided significant catheter-related cost savings of 43% in the taurolidine group vs. citrate group when overall expenses per patient and year were compared. Thus, use of taurolidine-based catheter lock solutions containing heparin and urokinase significantly reduced complications related to tunneled hemodialysis catheters when compared to four percent citrate solution and was overall more cost-efficient.

Pleural effusions in hematologic malignancies and their management with indwelling pleural catheters.

PURPOSE OF REVIEW: Pleural effusions in patients with hematologic malignancy may represent malignant pleural effusion (MPE) or occur secondary to infection, treatment effects, and other common causes. The impact of MPE on prognosis in this cohort remains unclear. Indwelling pleural catheters (IPCs) are routinely placed for palliation of recurrent symptomatic MPEs, but perceived concerns over infection and bleeding may limit their use in patients with hematologic malignancies. However, recent evidence suggests IPCs are both well tolerated and effective in this cohort. In this review, the evaluation of pleural effusions in hematologic malignancies and their management with an IPC are outlined. RECENT FINDINGS: Two retrospective studies have been published regarding the use of IPCs in hematologic malignancies. Lymphomatous effusions are the most common cause of MPE in this cohort. The rates of complications and pleurodesis with IPC in hematologic malignancies are similar to those with solid organ tumors. SUMMARY: Pleural effusions in patients with hematologic malignancies may be managed safely with an IPC. Sterile technique, barrier protection, standardized algorithms for placement and removal, and quality assurance initiatives are crucial to centers that place IPCs for all patients. The safety of IPC in hematologic malignancies warrants a paradigm shift in the management of pleural disease for this cohort.

A randomized controlled trial and cost-effectiveness analysis of early cannulation arteriovenous grafts versus tunneled central venous catheters in patients requiring urgent vascular access for hemodialysis.

OBJECTIVE: Early cannulation arteriovenous grafts (ecAVGs) are proposed as an alternative to tunneled central venous catheters (TCVCs) in patients requiring immediate vascular access for hemodialysis (HD). We compared bacteremia rates in patients treated with ecAVG and TCVC. METHODS: The study randomized 121 adult patients requiring urgent vascular access for HD in a 1:1 fashion to receive an ecAVG with or without (+/-) an arteriovenous fistula (AVF; n = 60) or TCVC+/-AVF (n = 61). Patients were excluded if they had active systemic sepsis, no anatomically suitable vessels, or an anticipated life expectancy <3 months. The primary end point was the culture-proven bacteremia rate at 6 months, with the trial powered to detect a reduction in bacteremia from 24% to 5% (α = .05, ß = .8). Secondary end points included thrombosis, reintervention, and mortality. A cost-effectiveness analysis was also performed. RESULTS: Culture-proven bacteremia developed in 10 patients (16.4%) in the TCVC arm ≤6 months compared with two (3.3%) in the ecAVG+/-AVF arm (risk ratio, 0.2; 95% confidence interval, 0.12-0.56; P = .02). Mortality was also higher in the TCVC+/-AVF cohort (16% [n = 10] vs 5% [n = 3]; risk ratio, 0.3; 95% CI, 0.08-0.45; P = .04). The difference in treatment cost between the two arms was not significant (£11,393 vs £9692; P = .24). CONCLUSIONS: Compared with TCVC+/-AVF, a strategy of ecAVG+/-AVF reduced the rate of culture-proven bacteremia and mortality in patients requiring urgent vascular access for HD. The strategy also proved to be cost-neutral.

Cost-effectiveness of indwelling pleural catheter compared with talc in malignant pleural effusion.

BACKGROUND AND OBJECTIVE: Malignant pleural effusion is associated with morbidity and mortality. A randomized controlled trial previously compared clinical outcomes and resource use with indwelling pleural catheter (IPC) and talc pleurodesis in this population. Using unpublished quality of life data, we estimate the cost-effectiveness of IPC compared with talc pleurodesis. METHODS: Healthcare utilization and costs were captured during the trial. Utility weights produced by the EuroQol Group five-dimensional three-level questionnaire and survival were used to determine quality-adjusted life-years (QALYs) gained. The incremental cost-effectiveness ratio (ICER) was calculated over the 1-year trial period. Sensitivity analysis used patient survival data and modelled additional nursing time required per week for catheter drainage. RESULTS: Utility scores, cost and QALYs gained did not differ significantly between groups. The ICER for IPC compared with talc was favorable at $US10 870 per QALY gained. IPC was less costly with a probability exceeding 95% of being cost-effective when survival was <14 weeks, and was more costly when 2-h nursing time per week was assumed for catheter drainage. CONCLUSION: IPC is cost-effective when compared with talc, although substantial uncertainty exists around this estimate. IPC appears most cost-effective in patients with limited survival. If significant nursing time is required for catheter drainage, IPC becomes less likely to be cost-effective. Either therapy may be considered as a first-line option in treating malignant pleural effusion in patients without history of prior pleurodesis, with consideration for patient survival, support and preferences.

The incidence and costs of bacteremia due to lack of gentamicin lock solutions for dialysis catheters.

The use of antibiotic lock solutions as prophylaxis for catheter-associated blood stream infection (CRBSI) has been shown to be effective in previous randomized controlled trials. However, the cost-effectiveness of this approach had not been studied. In 2012, the routine gentamicin-heparin lock solution used in Auckland City Hospital was withdrawn from the market, leading to a change to heparin-only lock. This was then replaced with gentamicin-citrate lock in 2014. This situation allowed review of the CRBSI rate and financial impact of different catheter lock solutions. A retrospective audit was performed from 1 January 2011 to 31 December 2015 to investigate the rate of culture-proven CRBSI in patients with tunneled cuffed dialysis catheters. There were 89 cases of CRBSI involving 64 patients in the 5-year period. In comparison with the heparin-only lock, both gentamicin-heparin and gentamicin-citrate locks had a significantly lower rate of bacteremia, with rate ratios of 0.46 (confidence interval 0.30-0.72) and 0.11 (confidence interval 0.05-0.22), respectively. The inpatient costs as a consequence of the CRBSI were NZ$27 792 per 1000 catheter days for heparin-only lock, NZ$10 608.56 per 1000 catheter days for gentamicin-heparin lock, and NZ$ 1898.45 per 1000 catheter days for gentamicin-citrate lock. The lack of antibiotic lock solutions led to an increase in bacteremia rates and higher financial cost for inpatient management of bacteremia. Our findings highlight the importance of consistent supply of pharmaceuticals.

A mixed-methods investigation of incident Hemodialysis access in a safety-net population.

BACKGROUND: Despite improved health outcomes associated with arteriovenous fistulas, 80% of Americans initiate hemodialysis using a catheter, influenced by low socioeconomic status among other factors. Risk factors for incident catheter use in safety-net populations are unknown. Our objective was to identify factors associated with incident catheter use among hemodialysis patients at one safety-net hospital, with a goal of informing fistula placement initiatives targeted at safety-net populations more generally. METHODS: We performed a retrospective review of all incident hemodialysis patients at a single urban safety-net hospital from January 1, 2010 - December 31, 2015 (n = 241), as well as semi-structured interviews with a multi-lingual convenience sample of patients (n = 10) from this cohort. The primary outcome was incident vascular access modality. Multivariable logistic regression was used to identify factors associated with incident catheter use. Interview transcripts were coded using a directed content analysis framework based on a model describing barriers to healthcare access. RESULTS: Subjects were 61.8% male, racially/ethnically diverse (19.5% white, 29.5% black, 28.6% Hispanic, 17.4% Asian), with a mean age of 52.4 years. Eighty-eight percent initiated hemodialysis using a catheter. In multivariable analysis, longer duration of nephrology care was associated with decreased catheter use (>12 months vs. 0-6 months: adjusted Odds Ratio [aOR] 0.07, 95% CI 0.02-0.23, p < 0.001), whereas uninsured status increased odds of catheter use (aOR 3.96, 1.23-12.76, p = 0.02). There was a decrease in catheter use after vascular surgery services became available in-hospital (OR 0.40, 95% CI 0.16-0.98, p = 0.04), however this association was not significant in multivariable analysis (aOR 0.48, 0.17-1.36, p = 0.17). During interviews, patients cited emotional responses to disease, lack of social and financial resources, and limited health knowledge as barriers to obtaining fistula surgery. CONCLUSIONS: The rate of catheter use in this urban safety-net population is above the national average. Access to health insurance, early referrals to nephrology, and provision of in-hospital vascular surgery should be prioritized in the safety-net. Additionally, services that support patients' emotional and learning needs may decrease delays in fistula placement.

Liposomal Bupivacaine Mixture Has Similar Pain Relief and Significantly Fewer Complications at Less Cost Compared to Indwelling Interscalene Catheter in Total Shoulder Arthroplasty.

BACKGROUND: The efficacy and costs of indwelling interscalene catheter (ISC) and liposomal bupivacaine (LBC), with and without adjunctive medications, in patients with primary shoulder arthroplasty are a source of current debate. METHODS: In 214 arthroplasties, 156 patients had ISC and 58 had LBC injections that were mixed with morphine, ketorolac, and 0.5% bupivacaine with epinephrine. Charts were reviewed for visual analog scale pain scores, oral morphine equivalent (OME) usage, major complications, and costs. RESULTS: Visual analog scale scores were not significantly different at 24 hours or at 2, 6, and 12 weeks. Average OME consumption at 24 hours was significantly more with LBC, but was not significantly different at 12 weeks. Relative risk of a major complication was nearly 4 times higher with ISC than with LBC. The average cost for the LBC mixture was $289.04, and for ISC, including equipment and anesthesia fees, was $1559.42. CONCLUSION: The intraoperative LBC mixture provided equivalent pain relief with significantly fewer major complications and at markedly lower cost than ISC. LBC required almost twice as much OME to attain the same level of pain relief at 24 hours, but there was no significant difference in the cumulative amount of outpatient narcotic use.

Cost analysis of the Hemodialysis Reliable Outflow (HeRO) Graft compared to the tunneled dialysis catheter.

BACKGROUND: In end-stage renal disease patients with central venous obstruction, who have limited vascular access options, the Hemodialysis Reliable Outflow (HeRO) Graft is a new alternative with a lower incidence of complications and longer effective device life compared to tunneled dialysis catheters (TDCs). We undertook an economic analysis of introducing the HeRO Graft in the UK. METHODS: A 1-year cost-consequence decision analytic model was developed comparing management with the HeRO Graft to TDCs from the perspective of the National Health Service in England. The model comprises four 3-month cycles during which the vascular access option either remains functional for hemodialysis or fails, patients can experience access-related infection and device thrombosis, and they can also accrue associated costs. Clinical input data were sourced from published studies and unit cost data from National Health Service 2014-15 Reference Costs. RESULTS: In the base case, a 100-patient cohort managed with the HeRO Graft experienced 6 fewer failed devices, 53 fewer access-related infections, and 67 fewer device thromboses compared to patients managed with TDCs. Although the initial device and placement costs for the HeRO Graft are greater than those for TDCs, savings from the lower incidence of device complications and longer effective device patency reduces these costs. Overall net annual costs are £2600 for each HeRO Graft-managed patient compared to TDC-managed patients. If the National Health Service were to reimburse hemodialysis at a uniform rate regardless of the type of vascular access, net 1-year savings of £1200 per patient are estimated for individuals managed with the HeRO Graft. CONCLUSIONS: The base case results showed a marginal net positive cost associated with vascular access with the HeRO Graft compared with TDCs for the incremental clinical benefit of reductions in patency failures, device-related thrombosis, and access-related infection events in a patient population with limited options for dialysis vascular access.

Repeat Large-Volume Paracentesis Versus Tunneled Peritoneal Catheter Placement for Malignant Ascites: A Cost-Minimization Study.

OBJECTIVE: The objective of this study was to determine the point in time at which tunneled peritoneal catheter placement becomes less costly than repeat large-volume paracentesis (LVP) for patients with malignant ascites. MATERIALS AND METHODS: Procedure costs were based on 2013 Medicare reimbursement rates. Rates for specific complications were obtained from the literature and were assigned costs. A decision tree-based Markov chain Monte Carlo model was designed with 11 cycles of 10 days, to simulate 4000 subjects per trial. Patients were grouped according to initial treatment decision (LVP vs catheter placement), and the total cost at the end of each 10-day cycle was calculated. The point at which catheter placement became less costly than LVP was determined. Additional simulations were used for bivariate analyses of all cost and probability variables and for trivariate analysis of cycle length and volume of fluid drained per cycle. RESULTS: Individual input probabilities were not significantly different from corresponding simulation outcomes (p value range, 0.068-0.95). When complications were included in the model, the cost curves crossed at a mean (± SD) of 82.8 ± 3.6 days (range, 75.8-89.6 days), corresponding to a time between the performance of the ninth and 10th LVP procedures. Intersection occurred earlier in simulations with a shorter cycle length and less fluid per cycle, but it was minimally affected by changing individual complication probabilities and costs. CONCLUSION: For patients with malignant ascites, LVP becomes more costly once the procedure is performed nine or 10 times or at approximately 83 days, if paracentesis is repeated every 10 days, with 5 L of fluid removed each time. Use of a tunneled peritoneal catheter improves the cost advantage for patients who receive LVP more frequently or patients who have less than 5 L of fluid drained per procedure.

Indwelling pleural catheters for malignant pleural effusion.

Pleural effusions are a common cause of symptoms in patients with malignancy and can adversely affect quality of life. However, not all effusions in the setting of malignancy are due to the cancer itself and therefore it is essential to perform an extensive assessment to diagnose the underlying aetiology. There are a number of treatment options available to manage a malignant effusion and reduce the associated symptomatology. The choice of intervention depends on a number of factors and, in particular, patient preference. In this paper, we will discuss the role of an indwelling pleural catheter in the outpatient management of individuals with malignant effusions.

Cost effectiveness of different central venous approaches for port placement and use in adult oncology patients: evidence from a randomized three-arm trial.

BACKGROUND: No randomized trials have so far investigated the cost effectiveness of different methods for implantation and use of central venous ports in oncology patients. PATIENTS AND METHODS: Overall, 403 patients eligible for receiving intravenous chemotherapy for solid tumours were randomly assigned to implantation of a single type of port, either through a percutaneous landmark access to the internal jugular vein, an ultrasound (US)-guided access to the subclavian vein, or a surgical cut-down access through the cephalic vein at the deltoid-pectoralis groove. Insertion and maintenance costs were estimated by obtaining the charges for an average implant and use, while the costs of the management of complications were analytically assessed. The total cost was defined as the purchase cost plus the insertion cost plus the maintenance cost plus the cost of treatment of the complications, if any. RESULTS: A total of 401 patients were evaluable-132 with the internal jugular vein, 136 with the subclavian vein and 133 with the cephalic vein access. No differences were found for the rate of early complications. The US-guided subclavian insertion site had significantly lower failures. Infections occurred in 1, 3, and 3 patients (internal jugular, subclavian, and cephalic access, respectively; p = 0.464), whereas venous thrombosis was observed in 15, 8, and 11 patients, respectively (p = 0.272). Mean cost for purchase, implantation, diagnosis and treatment of complications in each patient was 2,167.85 for subclavian US-guided, 2,335.87 for cephalic, and 2,384.10 for internal jugular access, respectively (p = 0.0001). CONCLUSION: US real-time guidance to the subclavian vein resulted in the most cost-effective method of central venous port placement and use.

Risk of infection due to medical interventions via central venous catheters or implantable venous access port systems at the middle port of a three-way cock: luer lock cap vs. luer access split septum system (Q-Syte).

BACKGROUND: Many cancer patients receive a central venous catheter or port system prior to therapy to assure correct drug administration. Even appropriate hygienic intervention maintenance carries the risk of contaminating the middle port (C-port) of a three-way cock (TWC), a risk that increases with the number of medical interventions. Because of the complexity of the cleaning procedure with disconnection and reconnection of the standard luer lock cap (referred as "intervention"), we compared luer lock caps with a "closed access system" consisting of a luer access split septum system with regard to process optimization (work simplification, process time), efficiency (costs) and hygiene (patient safety). METHODS: For determination of process optimization the workflow of an intervention according to the usual practice and risks was depicted in a process diagram. For determining the actual process costs, we analyzed use of material and time parameters per intervention and used the process parameters for programming the process into a simulation run (n = 1000) to determine the process costs as well as their differences (ACTUAL vs. NOMINAL) within the framework of a discrete event simulation.Additionally cultures were carried out at the TWC C-ports to evaluate possible contamination. RESULTS: With the closed access system, the mean working time of 5.5 minutes could be reduced to 2.97 minutes. The results for average process costs (labour and material costs per use) were 3.92 € for luer lock caps and 2.55 € for the closed access system. The hypothesis test (2-sample t-test, CI 0.95, p-value<0.05) confirmed the significance of the result.In 50 reviewed samples (TWC's), the contamination rate for the luer lock cap was 8% (4 out of 50 samples were positive), the contamination rate of the 50 samples with the closed access system was 0%.Possible hygienic risks (related to material, surroundings, staff handling) could be reduced by 65.38%. CONCLUSIONS: In the present research, the closed access system with a divided split septum was superior to conventional luer lock caps. The advantage of the closed access system lies in the simplified handling for staff, which results in a reduced risk of patient infection due to improved clinical hygiene.

Indwelling pleural catheters.

Indwelling pleural catheters (IPC) are now established as one of the major tools for the management of recurrent pleural effusions. Their traditional role, which saw them only as second line treatment for malignant effusions, has now expanded. Recent evidence has not only suggested that they may be effectively employed as first-line therapy in some malignant cases, but that there is a wider spectrum of diseases which may be managed by their use. The majority of patients are likely to experience symptomatic benefit and some may also go on to achieve pleurodesis. IPCs are relatively simple to insert and maintain, and theoretically allow patients to be managed entirely as an outpatient, meaning that they are likely to be cost-effective in the longer term. They can also dramatically improve the quality of life in patients who have typically needed lengthy hospital admissions or who have terminal malignant disease.

Resource Use and Costs of Indwelling Pleural Catheters versus Pleurodesis for Malignant Pleural Effusions: A Population-based Study.

Rationale: Malignant pleural effusions (MPEs) are associated with significant health service use and healthcare costs, but the current evidence is limited. Objectives: To compare 12-month post-procedure: 1) health service utilization; and 2) healthcare costs after indwelling pleural catheter (IPC) insertion with at-home drainage performed by home care nursing services, versus in-hospital chemical pleurodesis. Methods: We performed a retrospective population-based study on a cohort of adults with MPEs who underwent IPC insertion or chemical pleurodesis between January 1, 2015 and December 31, 2019 using provincial health administrative data (Ontario, Canada). Patients were followed from the procedure date until death or until 12 months after the procedure. Inverse probability of treatment weighting was performed to adjust for imbalances in baseline characteristics. Differences in length of stay, readmissions, emergency department visits, home care visits, and healthcare costs were estimated using weighted regression analysis. Results: Of 5,752 included individuals, 4,432 (77%) underwent IPC insertion and 1,320 (23%) had pleurodesis. In the weighted sample, individuals who received an IPC had fewer inpatient days (12.4 d vs. 16 d; standardized mean difference, 0.229) but a higher proportion of subsequent admissions for empyema (2.7% vs. 1.1%; P = 0.0002) than those undergoing pleurodesis. Individuals with IPCs received more hours of nursing home care (41 h vs. 21.1 h; standardized mean difference, 0.671) but overall had lower average healthcare costs ($40,179 vs. $46,640 per patient; standardized mean difference, 0.177) than those receiving pleurodesis. Conclusions: IPCs with home nursing drainage are associated with reduced health resource use compared with pleurodesis in adults with MPEs, even after controlling for important baseline and clinical characteristics. Given that both procedures have similar health outcomes, our findings support the ongoing promotion of IPCs to increase outpatient management of patients with MPEs.
