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.

Time considerations and outcomes in pediatric tracheostomy decannulation.

OBJECTIVE: The study objective is to identify factors that impact the time to decannulation in pediatric patients ages 0 through 18 years who are tracheostomy-dependent. METHODS: This retrospective chart review from January 1, 2005 through December 31, 2020 identified pediatric tracheostomy patients at a single pediatric institution. Data extracted included demographic, socioeconomic factors, and clinical characteristics. Multivariate regression and survival analysis were used to identify factors associated with successful decannulation and decreased time with tracheostomy. RESULTS: Of the 479 tracheostomy-dependent patients identified, 162 (33.8%) were decannulated. Time to decannulation ranged from 0.5 months to 189.2 months with median of 24 months (IQR 12.91-45.71). In the multivariate analysis, patients with bronchopulmonary dysplasia (p = 0.021) and those with Passy-Muir® Valve at discharge (p = 0.015) were significantly associated with decannulation. In contrast, neurologic comorbidities (p = 0.06), presence of gastrostomy tube (p < 0.001), or discharged on a home ventilator (p < 0.001) were associated with indefinite tracheostomy. When adjusting for age, sex, race, ethnicity, and insurance status, for every one month delay in establishment of outpatient otolaryngology care, time to decannulation was delayed by 0.5 months (p = 0.010). For each additional outpatient otolaryngology follow-up visit, time to decannulation increased by 3.36 months (p < 0.001). CONCLUSIONS: Decannulation in pediatric tracheostomy patients is multifactorial. While timely establishment of outpatient care did correlate with quicker decannulation, factors related to medical complexity may have a greater impact on time to decannulation. Our results can help guide institutional decannulation protocols, as well as provide guidance when counseling families regarding tracheostomy expectations.

Comparison of success and cost after retrieval of two inferior vena cava filters.

OBJECTIVE: The objective of this study was to help guide inferior vena cava (IVC) filter choices by better understanding the retrieval characteristics, complications, and total costs between two commonly used IVC filters. METHODS: All patients who underwent retrieval or attempted retrieval of Denali (Bard Peripheral Vascular) or Option (Argon Medical Devices) IVC filters were identified between March 2016 and October 2021 at a single tertiary care center. Those with imaging studies that permitted evaluation of filter placement, presence or degree of tilt, and/or hooking of the filter into the IVC wall were included in the present study. Filter retrieval success, number of attempts, use of advanced techniques, and fluoroscopy and procedural times were recorded and compared between the two filters. RESULTS: A total of 87 patients presented for retrieval of 52 Denali and 35 Option Elite filters during the study period. Denali filters were more likely to be successfully retrieved at the first attempt (94% vs 77%; P = .019). The procedural and fluoroscopy times were shorter for Denali filters (29 minutes vs 63 minutes [P < .001] and 7 minutes vs 25 minutes [P < .001], respectively). Denali filters were less likely to be significantly tilted (≥15○) at retrieval (12% vs 29%; P < .001) or to have the filter hook embedded in the IVC wall (6% vs 40%; P < .001). Tilting of the filter of ≥15○ had no significant effects on the retrieval success rate (no tilt or tilt <15○ vs tilt of ≥15○: 98% vs 100%; P = .58). In contrast, filter hook penetration into the IVC wall significantly reduced successful recovery (41% vs 99%; P < .001). CONCLUSIONS: The findings from this study suggest that although the filter designs are similar, a benefit exists in the ease of retrievability of the Denali over the Option filter. We found that tilting and hooking of the filter in the IVC wall occurred significantly more with the Option filter. These factors likely made retrieval more difficult and contributed to the longer procedure and fluoroscopy times.

Supply Costs in Complex and Routine Inferior Vena Cava Filter Retrieval: 10 Years' Data from a Single Center.

PURPOSE: To characterize the medical supply costs associated with inferior vena cava filter retrieval (IVCFR) using endobronchial forceps (EFs), a snare, or Recovery Cone (RC). MATERIALS AND METHODS: In total, 594 of 845 IVCFRs attempted at a tertiary referral hospital between October 1, 2012, and June 20, 2022 were categorized by intended retrieval strategy informed by, rotational cavography as follows: (a) EF (n = 312) for tilted or tip-embedded/strut-embedded filters and for long-dwelling closed-cell filters and (b) a snare (n = 255) or (c) RC (n = 27) for other well-positioned filters with or mostly without hooks, respectively. List prices of relevant supplies at time of retrieval were obtained or, rarely, estimated using a standard procedure. Contrast use, fluoroscopic time, filter type, dwell time, and patient age and sex were recorded. Mean between-group cost differences were estimated by linear regression, adjusting for date. Additional models evaluated filter type, dwell time, and patient-level effects. RESULTS: Of the 594 IVCFRs, 591 were successful, whereas 2 EF and 1 snare retrievals failed. Moreover, 4 EF retrievals were successful with a snare and 2 with smaller EF, 12 snare retrievals were successful with EF, 1 RC retrieval was successful with a snare and 2 with EF. Principal model indicated a significantly lower mean cost of EF ($564.70, SE ± 9.75) than that of snare ($811.29, SE ± 10.83; P < .0001) and RC ($1,465.48, SE ± 47.12; P < .0001) retrievals. Adjusted models yielded consistent results. Had all retrievals been attempted with EF, estimated undiscounted full-period supplies savings would be $87,201.51. CONCLUSIONS: EFs are affordable for complex IVCFR, and extending their use to routine IVCFR could lead to considerable cost savings.

Cost-per-Response Analysis of Pure Hypochlorous Acid Among Patients with Chronic Venous Leg Ulcers: A Health Economic Analysis.

OBJECTIVE: To estimate the total cost-per-wound healing response (CPR) and the per-day CPR of patients with chronic leg ulcers treated with pure hypochlorous acid (pHA) as part of their overall would healing regimen. METHODS: The authors developed a deterministic decision-tree model to estimate the incremental CPR for pHA. The analysis was performed using clinical data from a published single-arm prospective study. The outcome of interest was re-epithelialization at 90 days. Economic data for pHA were based on public prices of pHA per dressing change from the wound care center perspective. The following time points were assessed: 90, 60, and 30 days. Dressing changes occurred every 2.5 days. Sensitivity analysis was performed to gauge the robustness of the results. RESULTS: A total of 31 patients (68% women) with 31 lesions (average age of wound, 29 months; range, 1-240 months) were included in the clinical study. Re-epithelialization occurred in 23 lesions (74%) at 90 days, 17 (55%) at 60 days, and 3 (10%) at 30 days. The total CPRs were $75.69, $68.27, and $193.44, and the per-day CPRs were $0.84, $1.13, and $6.45 at 90, 60, and 30 days, respectively. The sensitivity analysis revealed that CPRs ranged from $0.63 to $1.12 per day at 90 days. CONCLUSIONS: Incorporating pHA into standard wound healing protocols is a minimal added expense and may yield a substantial economic savings of $2,695 at 90 days.

The impact of single-use digital flexible cystoscope for double J removal on hospital costs and work organization: A multicentric evaluation.

BACKGROUND: Isiris-α® is a single-use digital flexible cystoscope with an integrated grasper designed for double J (DJ) stent removal. Aim of this study was to conduct a multicentric evaluation of the costs and criticalities of stent removals performed with Isiris®-α in different hospitals and health systems, as compared to other DJ removal procedures. METHODS: After gathering 10 institutions worldwide with experience on Isiris-α®, we performed an analysis of the reported costs of DJ removal with Isiris-α®, as compared to the traditional reusable equipment used in each institution. The cost evaluation included instrument purchase, Endoscopic Room (EnR)/ Operatory Room (OR) occupancy, medical staff, instrument disposal, maintenance, repairs, decontamination or sterilization of reusable devices. RESULTS: The main factor affecting the costs of the procedure was OR/EnR occupancy. Decontamination and sterilization accounted for a less important part of total costs. Isiris-α® was more profitable in institutions where DJ removal is usually performed in the EnR/OR, allowing to transfer the procedure to outpatient clinic, with a significant cost saving and EnR/OR time saving to be allocated to other activities. In the only institution where DJ removal was already performed in outpatient clinics, there is a slight cost difference in favor of reusable instruments in high-volume institutions, given a sufficient number to guarantee the turnover. CONCLUSION: Isiris-α® leads to significant cost benefit in the institutions where DJ removal is routinely performed in EnR/OR, and brings significant improvement in organization, cost impact and turnover.

Device profile of the Orchid safety release valve for the prevention of accidental catheter dislodgement.

INTRODUCTION: More than 4 out of 5 patients in acute care require intravenous catheters. Complications of catheter dislodgement and failure are commonly reported at rates of 15-69% causing interrupted treatment and greater resource consumption when catheter replacement is required. AREAS COVERED: This manuscript outlines unmet needs in the prevention of catheter dislodgement and how a novel safety release device (Orchid SRV™, Linear Health Sciences) might address these gaps based on available evidence. EXPERT OPINION: Healthcare initiatives focus on reducing complications and associated costs with the delivery of intravenous treatments. Tension-activated safety release valve devices, attached to intravenous tubing, are a new feature that adds a level of safety to intravenous catheters to reduce mechanical catheter dislodgement when a pull force of greater than 3 pounds is applied. Incorporating a tension-activated accessory into and between existing intravenous tubing and the catheter and extension set protects the catheter from dislodgement. Flow continues until excessive pull force separates and closes the flow pathway in both directions, while the SRV provides a quick replacement to reestablish flow. The safety release valve is used to prevent accidental catheter dislodgement, limit tubing contamination, and avoid more serious complications while maintaining a functional catheter.

It is common for intravenous treatment to be disrupted due to accidental dislodgement of the catheter. Once this happens, the catheter must be replaced. This dislodgement may cause patient discomfort, loss of intravenous access to treatment, increase the chance of catheter failure due to blockage, and increase the risk of life-threatening infection. A new tension release device, the Orchid SRV, is designed to increase patient safety with a release valve, activated with any pulling force on the connected tubing, to prevent dislodgement and complications associated with catheter failure.

Prevalence, management, and prediction of venous access site occlusion in patients undergoing lead revision surgery.

BACKGROUND: Implantable electronic cardiac devices (CIED) have emerged as an essential component in the treatment of cardiac arrhythmias and heart failure. Due to increased life expectancy, expanding indications and limited technical survival, an increasing number of revision procedures can be anticipated. Venous access site occlusion (VASO) is the main obstacle during revision surgery. In this retrospective study we evaluated the prevalence, predictive parameters and operative management of venous access site occlusion. METHODS AND RESULTS: Between 01/2016 and 12/2020 304 patients underwent lead revision surgery of transvenous CIED in our department. Prevalence of VASO was 25.7% (n = 78), one patient was symptomatic. Independent predicting clinical parameters were male sex (2.86 (1.39-5.87), p < 0.01) and lead age (1.11 (1.05-1.18), p < 0.01)). Revision surgery despite VASO was successful in 97.4% (n = 76) without prolongation of the total surgery time or higher complication rates. Yet, lead extraction was possible in 92% of patients with VASO vs. 98.2% of patients without VASO (p 0.01). CONCLUSION: VASO is a frequent condition in patients undergoing lead revision surgery, but successful revision is feasible in most cases without preceding lead extraction. However, the lower success rates of lead extractions may be prognostically relevant, especially for younger patients.

Cost-effectiveness of on-demand removal of syndesmotic screws.

PURPOSE: Syndesmotic screw removal following acute syndesmotic injury is a commonly performed procedure. However, recent studies suggest that the removal does not result in improved patient reported outcome, while the procedure has proved not to be without complications. The aim of this study was to present a health-economic evaluation of on-demand removal (ODR) compared to routine removal (RR) of the syndesmotic screw. METHODS: Data were collected from the RODEO trial, a randomized controlled non-inferiority trial comparing functional outcome of ODR with RR. Economic evaluation resulted in total costs, costs (in Euro) per quality adjusted life year (QALY) and costs per point improvement on the Olerud Molander Ankle Score (OMAS). This included both direct and indirect costs. RESULTS: Total costs for ODR were significantly lower with a mean difference of 3160 euro compared to RR (p < 0.001). The difference in QALY was not significant. The difference in OMAS at 12 months was 1.79 with an incremental cost-effectiveness ratio (ICER) of €-1763 (p = 0.512). The ICER was well below the willingness to pay. Although unit costs might vary between hospitals and countries, these results provide relevant data of cost-effectiveness. CONCLUSION: The clinical effectiveness of both ODR and RR can be considered equal. The costs are lower for patients treated with ODR, which leads to the conclusion that ODR is cost-effective.

Cost Burden and Cost Influencers of Inferior Vena Cava Filter Placement and Retrieval among Medicare Beneficiaries with Acute Venous Thromboembolism.

PURPOSE: To examine the frequency, costs, and cost influencers of inferior vena cava filters (IVCFs) placements and retrievals among a national sample of patients using Medicare data. MATERIALS AND METHODS: This retrospective cohort study used the U.S. Medicare 100% database, a nationally representative sample of all U.S. patients aged ≥65 years, from 2014 through 2020. Procedures and clinical characteristics were identified from the diagnosis and procedure codes on Medicare claims. Beneficiaries aged ≥65 years with newly diagnosed venous thromboembolism (VTE) were identified and followed to obtain data on IVCF placements and retrievals. Data on the costs of the index IVCF procedures and any subsequent IVCF placements and retrievals were obtained. Multivariate models were used to estimate the impact of patient and clinical characteristics on costs. RESULTS: Among 501,216 patients with newly diagnosed VTE, 4,995 (1%) received an IVCF placement; of these, 1,215 (24.3%) had a retrieval procedure. Beneficiaries with IVCF placements and retrievals differed from a demographic and clinical perspective than from those without. Costs varied by the site of service, VTE acuity, and VTE type. Cost influencers included age, race, census region, service location, and VTE type. CONCLUSIONS: IVCF placement costs were driven by baseline patient characteristics (age, race, geographic residence, acute VTE diagnosis, and inpatient site of service), whereas retrieval costs were driven by age and deep vein thrombosis diagnosis. Strategies to mitigate the retrieval costs or the need to retrieve IVCFs may reduce the overall cost burden of IVCFs.

Assessment of the impact of organisational model of transvenous lead extraction on the effectiveness and safety of procedure: an observational study.

OBJECTIVES: To estimate the impact of the organisational model of transvenous lead extraction (TLE) on effectiveness and safety of procedures. DESIGN: Post hoc analysis of patient data entered prospectively into a computer database. SETTING: Data of all patients undergoing TLE in three centres in Poland between 2006 and 2021 were analysed. PARTICIPANTS: 3462 patients including: 985 patients undergoing TLE in a hybrid room (HR), with cardiac surgeon (CS) as co-operator, under general anaesthesia (GA), with arterial line (AL) and with transoesophageal echocardiography (TEE) monitoring (group 1), 68 patients-TLE in HR with CS, under GA, without TEE (group 2), 406 patients-TLE in operating theatre (OT) using 'arm-C' X-ray machine with CS under GA and with TEE (group 3), 154 patients-TLE in OT with CS under GA, without TEE (group 4), 113 patients-TLE in OT with anaesthesia team, using the 'arm-C' X-ray machine, without CS (group 5), 122 patients-TLE in electrophysiology lab (EPL), with CS under intravenous analgesia without TEE and AL (group 6), 1614 patients-TLE in EPL, without CS, under intravenous analgesia without TEE and AL (group 7). KEY OUTCOME MEASURE: Effectiveness and safety of TLE depending on organisational model. RESULTS: The rate of major complications (MC) was higher in OT/HR than in EPL (2.66% vs 1.38%), but all MCs were treated successfully and there was no MC-related death. The use of TEE during TLE increased probability of complete procedural succemss achieving about 1.5 times (OR=1.482; p<0.034) and were connected with reduction of minor complications occurrence (OR=0.751; p=0.046). CONCLUSIONS: The most important condition to avoid death due to MC is close co-operation with cardiac surgery team, which permits for urgent rescue cardiac surgery. Continuous TEE monitoring plays predominant role in immediate decision on rescue sternotomy and improves the effectiveness of procedure.

Nurses' Involvement in the Development and Usability Assessment of an Innovative Peripheral Intravenous Catheterisation Pack: A Mix-Method Study.

Guaranteeing peripheral venous access is one of the cornerstones of modern healthcare. Recent evidence shows that the lack of adequate clinical devices can result in the provision of substandard care to patients who require peripheral intravenous catheterization (PIVC). To address this challenge, we aimed to develop a PIVC pack for adult patients and assess the usability of this new device. METHODS: Following a mix-method design, the PIVC pack development and usability assessment were performed in two phases with the involvement of its potential end-users (nurses). In phase one (concept and semi-functional prototype assessment), focus group rounds were conducted, and a usability assessment questionnaire was applied at each stage. In phase two (pre-clinical usability assessment), a two-arm crossover randomised controlled trial (PIVC pack versus traditional material) was conducted with nurses in a simulated setting. Final interviews were conducted to further explore the PIVC pack applicability in a real-life clinical setting. RESULTS: High average usability scores were identified in each study phase. During the pre-clinical usability assessment, the PIVC pack significantly reduced procedural time (Z = -2.482, p = 0.013) and avoided omissions while preparing the required material (Z = -1.977, p = 0.048). The participating nurses emphasised the pack's potential to standardise practices among professionals, improve adherence to infection control recommendations, and enhance stock management. CONCLUSIONS: The developed pack appears to be a promising device that can assist healthcare professionals in providing efficient and safe care to patients requiring a PIVC. Future studies in real clinical settings are warranted to test its cost-effectiveness.

Complications in Device Therapy: Spectrum, Prevalence, and Management.

PURPOSE OF REVIEW: Cardiac implantable electronic device implant numbers are continually increasing due to the expanding indications and ageing population. This review explores the complications associated with device therapy and discusses ways to minimise and manage such complications. RECENT FINDINGS: Complications related to device therapy contribute to mortality and morbidity. Recent publications have detailed clear guidelines for appropriate cardiac device selection, as well as consensus documents discussing care quality and optimal implantation techniques. There have also been advances in device technologies that may offer alternative options to patients at high risk of/or already having encountered a complication. Adherence to guidelines, appropriate training, and selection of device, in addition to good surgical technique are key in reducing the burden of complications and improving acceptability of device therapy.

The cost of CIED infectious complications treatment in Poland from the perspective of Polish hospitals.

INTRODUCTION: Cardiac implantable electronic devices (CIED) are a recognized form of therapy in cardiology. Apart from the benefits, the use of CIEDs is also associated with the risk of complications, and the most important ones influencing treatment results and prognosis are infectious complications. AIM: This study aimed to calculate the cost of treatment of CIED-related infections, including transvenous lead extraction and device reimplantation, from the perspective of a Polish hospital. METHODS: A retrospective analysis of hospitalization costs of patients referred to transvenous lead extraction (TLE) for CIED infection was performed. The study covers cases from three Polish reference centers specializing in the comprehensive treatment of cardiac electrotherapy complications. RESULTS: It was shown that the average cost of treating a CIED infection is 34 000 PLN (8010 EUR) and is the highest in the cardiac resynchronization therapy with defibrillator function (CRT-D) group, where it amounts to almost 50 000 PLN (11 440 EUR). Thus, treatment of CIED infections is associated with an average loss of 3000 PLN for the healthcare provider and the length of hospitalization has a major influence on final outcomes. CONCLUSIONS: The hospital cost of treatment of CIED-related infections was high and related mainly to the type of device and length of hospitalization. Despite the low utilization of costly extraction tools, the hospitalization was still likely to be unprofitable.

Population-Based Disparities in Inferior Vena Cava Filter Procedures Among Medicare Enrollees With Acute Venous Thromboembolism.

PURPOSE: Venous thromboembolism (VTE) imposes a significant clinical and financial burden on patients and society. Inferior vena cava filters (IVCFs) are considered for patients with absolute contraindications or failures of anticoagulation. However, studies examining the population-based disparities of IVCF placement and retrieval are limited. The association between patient and clinical characteristics in the likelihood of and time to IVCF placement and retrievals in a nationally representative cohort was examined. METHODS: Medicare patients aged ≥65 years with index VTE claims between 2015 and 2018 were followed through 2019 to identify IVCF placements and retrievals. Rates were compared using survival analysis methods. RESULTS: Of the 516,978 patients with VTE diagnoses, 5,864 (1.1%) had IVCFs placed, and 1,884 (32.1%) of those underwent retrieval procedures. Placement and retrieval rates varied significantly by demographics, comorbidity burden, and geographic region. From Cox regression, older age (hazard ratio [HR], 1.26; P < .0001), higher baseline comorbidity (Elixhauser) score (HR, 1.07; P < .0001), and outpatient (vs inpatient) site of VTE service (HR, 2.11; P < .0001) were associated with increased frequency of IVCF placement. The rate of retrieval was significantly lower for men (HR, 0.83; P = .0393), patients with higher comorbidity scores (HR, 0.95; P = .0037), and those with outpatient (vs inpatient) VTE sites of service (HR, 0.77; P = .0173). Neither facility- nor county-level characteristics were significantly associated with placements or retrievals. CONCLUSIONS: This large cohort of Medicare beneficiaries with newly diagnosed VTE demonstrated inequities in IVCF placement and retrieval.

A review of the incidence, outcome, and management of venous stent migration.

BACKGROUND: Percutaneous endovenous stenting has emerged during the past decade as the primary method of treating symptomatic venous outflow obstruction. A recognized complication of venous stenting is stent migration. The aim of the present systematic review was to identify the number of cases of stent migration in reported studies to recognize the risk factors that might be associated with this complication and the outcomes following migration. METHODS: A review was conducted in accordance with the MOOSE (meta-analyses of observational studies in epidemiology) and PRIMSA (preferred reporting items for systematic review and meta-analysis) guidelines and registered in the PROSPERO. MEDLINE, EMBASE, and PubMed databases. Key references were searched using specified keywords. All relevant data for the primary procedure and subsequent presentation with stent migration were retrieved. The data were assessed as too low in quality to allow for statistical analysis. RESULTS: Between 1994 and 2020, 31 studies were identified, including 29 case reports and 2 case series, providing data for 54 events of venous stent migration with some data provided regarding the stent used for 47 of the events. The mean age of the 52 patients with stent migration was 50 years (range, 19-88 years) and 30 were men (57.6%). The stents for most of the reported cases were ≤60 mm in length (38 of 46; 82.6%). Only three of the reports were of stents >14 mm in diameter (3 of 47; 3.6%). None of the studies had reported migration of stents >100 mm long. In 85% of the migrated stent events, retrieval was attempted, with 65.2% via an endovascular approach. The immediate outcome was satisfactory for 100% of the reported attempts, whether by an endovascular or open surgical approach. CONCLUSIONS: The findings from our literature review suggest that the risk of migration is rare but might be underreported. Most of reported cases had occurred with shorter and smaller diameter stents. The paucity of reported data and the short-term follow-up provided suggest that more formal data collection would provide a truer reflection of the incidence. However, clear strategies to avoid migration should be followed to prevent this complication from occurring.

Outpatient ureteric stent removal following kidney transplantation.

During a kidney transplant, a plastic tube (stent) is placed in the ureter, connecting the new kidney to the bladder, in order to keep the new join open during the initial phase of transplantation. The stent is then removed after a few weeks via a camera procedure (cystoscopy), as it is no longer needed. The present study compared performing this in the operating theatre or in clinic for transplanted patients using a new single-use type of camera with an integrated grasper system. The results have shown that it is safe and cost-effective to do this in clinic, despite patients being susceptible to infection after transplantation.

Assessment of Silicone Particle Migration Among Women Undergoing Removal or Revision of Silicone Breast Implants in the Netherlands.

Importance: Silicone breast implants have been on the market for breast augmentation or breast reconstruction for approximately 60 years but may lead to medical complications, also called breast implant illness. Objective: To evaluate the existence of silicone gel bleed and migration over a long time period, including the period in which the newer cohesive silicone gel breast implants were used. Design, Setting, and Participants: In this single-center case series, capsule tissue and lymph node samples were collected from women who underwent removal or revision of silicone breast implants from January 1, 1986, to August 18, 2020, and data were extracted from the pathological reports and revision of the histology if data were missing. All tissues were examined using standard light microscopy, some extended with modified oil red O staining and energy-dispersive radiographic spectroscopy. A total of 365 women had capsular tissue removed, including 15 patients who also had lymph nodes removed, and 24 women had only lymph nodes removed. Data were analyzed from January to May 2021. Exposures: Silicone breast implants. Main Outcomes and Measures: The main outcome was presence or absence of silicones inside or outside the capsule. One-way analysis of variance was used to determine significance between groups. Results: Among a total of 389 women with silicone breast implants (mean [SD] age, 50.5 [11.2] years), 384 women (98.8%) had silicone particles present in the tissues, indicating silicone gel bleed. In 337 women (86.6%), silicone particles were observed outside the capsule (ie, in tissues surrounding the capsule and/or lymph nodes), indicating silicone migration. In 47 women (12.1%), silicone particles were only present within the capsule. In 5 women (1.2%), no silicone particles were detected in the tissues. Patients were divided into 2 groups, with 46 women who received cohesive silicone gel breast implants and 343 women who received either an older or a newer type of breast implant. There were no differences in silicone gel bleed or migration between groups (silicone detected outside or inside capsule: 44 women [95.7%] vs 340 women [99.1%]; P = .19). Conclusions and Relevance: In this case series including women with noncohesive or cohesive silicone gel breast implants, silicone leakage occurred in 98.8% of women, indicating silicone gel bleed, and in 86.6% of women, migration of silicone particles outside the capsule was detected.

Analysis of Costs and Payments for Inferior Vena Cava Filter Retrieval in the Medicare Population.

Over the past decade, inferior vena cava (IVC) filter retrieval has been increasing, in part due to Food and Drug Administration recommendations and legal pressure. The costs and margin of IVC filter removal are poorly understood. Medicare claims data from 2016 for the 103 highest volume centers for IVC filter retrieval were examined. Pooled mean charges, costs, payments, and margin were calculated by institution. Mean ± SD charges, costs, and payments were $14,138.00 ± $8,400.48, $3,693.28 ± $2,294.27, and $1,949.82 ± $702.91, respectively. Average (range) margin was -$1,706.18 (-$7,509.93 to $362.77). The margin was negative in 99 of the 103 (96%) institutions evaluated. The most significant contributors to the total procedure cost were operating room, supplies, and recovery (44.5%, 23.5%, and 10.4%, respectively). While IVC filter retrieval is often medically indicated, it is typically associated with a financial loss under current reimbursement structure.

Determining Variable Costs in the Acute Urolithiasis Cycle of Care Through Time-Driven Activity-Based Costing.

OBJECTIVE: To characterize full cycle of care costs for managing an acute ureteral stone using time-driven activity-based costing. METHODS: We defined all phases of care for patients presenting with an acute ureteral stone and built an overarching process map. Maps for sub-processes were constructed through interviews with providers and direct observation of clinical spaces. This facilitated calculation of cost per minute for all aspects of care delivery, which were multiplied by associated process times. These were added to consumable costs to determine cost for each specific step and later aggregated to determine total cost for each sub-process. We compared costs of eight common clinical pathways for acute stone management, defining total cycle of care cost as the sum of all sub-processes that comprised each pathway. RESULTS: Cost per sub-process included $920 for emergency department (ED) care, $1665 for operative stent placement, $2368 for percutaneous nephrostomy tube placement, $106 for urology clinic consultation, $238 for preoperative center visit, $4057 for ureteroscopy with laser lithotripsy (URS), $2923 for extracorporeal shock wave lithotripsy, $169 for clinic stent removal, $197 for abdominal x-ray, and $166 for ultrasound. The lowest cost pathway ($1388) was for medical expulsive therapy, whereas the most expensive pathway ($8002) entailed a repeat ED visit prompting temporizing stent placement and interval URS. CONCLUSION: We found a high degree of cost variation between care pathways common to management of acute ureteral stone episodes. Reliable cost accounting data and an understanding of variability in clinical pathway costs can inform value-based care redesign as payors move away from pure fee-for-service reimbursement.
