Incidence and economics of transvenous ICD lead complications: Implications for tricuspid valve function and interventions.

BACKGROUND: Implantable cardioverter-defibrillators are used globally and are reliable, but complications related to transvenous leads remain a concern. Evidence related to the incidence and costs of those complications is heterogeneous with respect to scope and healthcare system. This analysis aims to create estimates of the incidence and costs of tricuspid valve (TV) complications, lead failures, and lead extractions from a single large real-world data set. METHODS AND RESULTS: This retrospective longitudinal cohort study used the deidentified Medicare Fee for Service administrative claims database. A total of 116 036 patients with de novo transvenous ICD implant were analyzed. Mean hospital costs were $26 903 for tricuspid valve complications, $20 851 for lead failures, and $22 278 for lead extractions. CONCLUSIONS: Transvenous ICD lead complications incur significant costs to patients, hospitals, and payers when they occur. Advancements in lead technology that reduce these complications could bring significant clinical and economic value.

Trends, Outcomes, and Economic Implications of Peritoneal Dialysis-Associated Peritonitis Hospitalizations: A National Cohort Study.

INTRODUCTION: Peritoneal dialysis-associated peritonitis (PDAP) is a serious complication of peritoneal dialysis, associated with significant morbidity, modality transition, and mortality. Here, we provide an update on the national burden of this significant complication, highlighting trends in demographics, treatment practices, and in-hospital outcomes of PDAP from 2016 to 2020. METHODS: Utilizing a national all-payer dataset of hospitalizations in the USA, we conducted a retrospective cohort study of adult hospitalizations with a primary diagnosis of PDAP from 2016 to 2020. We analyzed demographic, clinical, and hospital-level data, focusing on in-hospital mortality, PD catheter removal, length of stay, and healthcare expenses. Multivariable logistic regression adjusted for demographic and clinical covariates was employed to identify risk factors associated with adverse outcomes. RESULTS: There was a stable burden of annual PDAP admissions from 2016 to 2020. Healthcare expenditures associated with PDAP were high, totaling over USD 75,000 per admission. Additionally, our data suggest geographic inconsistencies in treatment patterns, with treatment at western and teaching hospitals associated with increased rates of catheter removal relative to northeastern and non-teaching centers and a mean cost of nearly USD 55,000 more in Western states compared to Midwest states. 23.2% of episodes resulted in the removal of the PD catheter. Risk factors associated with adverse outcomes included older age, higher Charlson comorbidity index scores, peripheral vascular disease, and the need for vasopressors. CONCLUSION: PDAP is a major cause of mortality among PD patients, and there is a vital need for future studies to examine the impact of hospital location and teaching status on PDAP outcomes, which can inform treatment practices and resource allocation.

Disposable grasper-integrated flexible cystoscope for ureteral stent removal in transplanted patients; focus on feasibility, safety, and patient experience. Results and micro-cost analysis from a tertiary referral center.

INTRODUCTION & OBJECTIVES: To evaluate ureteral stent removal (SR) using a grasper-integrated disposable flexible cystoscope (giFC-Isiris ®, Coloplast ®) after kidney transplantation (KT), with a focus on feasibility, safety, patient experience, and costs. MATERIAL AND METHODS: All consecutive KT undergoing SR through giFC were prospectively enrolled from January 2020 to June 2023. Patient characteristics, KT and SR details, urine culture results, antimicrobial prescriptions, and the incidence of urinary tract infections (UTI) within 1 month were recorded. A micro-cost analysis was conducted, making a comparison with the costs of SR with a reusable FC and grasper. RESULTS: A total of 136 KT patients were enrolled, including both single and double KT, with 148 stents removed in total. The median indwelling time was 34 days [26, 47]. SR was successfully performed in all cases. The median preparation and procedure times were 4 min [3,5]. and 45 s[30, 60], respectively. The median Visual Analog Scale (VAS) score was 3 [1, 5], and 98.2% of patients expressed willingness to undergo the procedure again. Only one episode of UTI involving the graft (0.7%) was recorded. Overall, the estimated cost per SR procedure with Isiris ® and the reusable FC was 289.2€ and 151,4€, respectively. CONCLUSIONS: This prospective series evaluated the use of Isiris ® for SR in a cohort of KT patients, demonstrating feasibility and high tolerance. The UTI incidence was 0.7% within 1 month. Based on the micro-cost analysis, estimated cost per procedure favored the reusable FC.

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.

Effect of infusion set replacement intervals on catheter-related bloodstream infections (RSVP): a randomised, controlled, equivalence (central venous access device)-non-inferiority (peripheral arterial catheter) trial.

BACKGROUND: The optimal duration of infusion set use to prevent life-threatening catheter-related bloodstream infection (CRBSI) is unclear. We aimed to compare the effectiveness and costs of 7-day (intervention) versus 4-day (control) infusion set replacement to prevent CRBSI in patients with central venous access devices (tunnelled cuffed, non-tunnelled, peripherally inserted, and totally implanted) and peripheral arterial catheters. METHODS: We did a randomised, controlled, assessor-masked trial at ten Australian hospitals. Our hypothesis was CRBSI equivalence for central venous access devices and non-inferiority for peripheral arterial catheters (both 2% margin). Adults and children with expected greater than 24 h central venous access device-peripheral arterial catheter use were randomly assigned (1:1; stratified by hospital, catheter type, and intensive care unit or ward) by a centralised, web-based service (concealed before allocation) to infusion set replacement every 7 days, or 4 days. This included crystalloids, non-lipid parenteral nutrition, and medication infusions. Patients and clinicians were not masked, but the primary outcome (CRBSI) was adjudicated by masked infectious diseases physicians. The analysis was modified intention to treat (mITT). This study is registered with the Australian New Zealand Clinical Trials Registry ACTRN12610000505000 and is complete. FINDINGS: Between May 30, 2011, and Dec, 9, 2016, from 6007 patients assessed, we assigned 2944 patients to 7-day (n=1463) or 4-day (n=1481) infusion set replacement, with 2941 in the mITT analysis. For central venous access devices, 20 (1·78%) of 1124 patients (7-day group) and 16 (1·46%) of 1097 patients (4-day group) had CRBSI (absolute risk difference [ARD] 0·32%, 95% CI -0·73 to 1·37). For peripheral arterial catheters, one (0·28%) of 357 patients in the 7-day group and none of 363 patients in the 4-day group had CRBSI (ARD 0·28%, -0·27% to 0·83%). There were no treatment-related adverse events. INTERPRETATION: Infusion set use can be safely extended to 7 days with resultant cost and workload reductions.

Outcomes and Cost Evaluation Related to a Single-Use, Disposable Ureteric Stent Removal System: a Systematic Review of the Literature.

PURPOSE OF REVIEW: To present the latest evidence related to the outcomes and cost of single-use, disposable ureteric stent removal system (Isiris). RECENT FINDINGS: Our review suggests that compared to a reusable flexible cystoscope (re-FC), a disposable flexible cystoscope (d-FC) with built-in grasper (Isiris) significantly reduced procedural time and provided a cost benefit when the latter was used in a ward or outpatient clinic-based setting. The use of d-FC also allowed endoscopy slots to be used for other urgent diagnostic procedures. Disposable FCs are effective and safe for ureteric stent removal. They offer greater flexibility and, in most cases, have been demonstrated to be cost-effective compared to re-FCs. They are at their most useful in remote, low-volume centres, in less well-developed countries and in centres where large demand is placed on endoscopy resources.

Wound infection following implant removal of foot, ankle, lower leg or patella; a protocol for a multicenter randomized controlled trial investigating the (cost-)effectiveness of 2 g of prophylactic cefazolin compared to placebo (WIFI-2 trial).

BACKGROUND: Elective implant removal (IR) after fracture fixation is one of the most common procedures within (orthopedic) trauma surgery. The rate of surgical site infections (SSIs) in this procedure is quite high, especially below the level of the knee. Antibiotic prophylaxis is not routinely prescribed, even though it has proved to lower SSI rates in other (orthopedic) trauma surgical procedures. The primary objective is to study the effectiveness of a single intravenous dose of 2 g of cefazolin on SSIs after IR following fixation of foot, ankle and/or lower leg fractures. METHODS: This is a multicenter, double-blind placebo controlled trial with a superiority design, including adult patients undergoing elective implant removal after fixation of a fracture of foot, ankle, lower leg or patella. Exclusion criteria are: an active infection, current antibiotic treatment, or a medical condition contraindicating prophylaxis with cefazolin including allergy. Patients are randomized to receive a single preoperative intravenous dose of either 2 g of cefazolin or a placebo (NaCl). The primary analysis will be an intention-to-treat comparison of the proportion of patients with a SSI at 90 days after IR in both groups. DISCUSSION: If 2 g of prophylactic cefazolin proves to be both effective and cost-effective in preventing SSI, this would have implications for current guidelines. Combined with the high infection rate of IR which previous studies have shown, it would be sufficiently substantiated for guidelines to suggest protocolled use of prophylactic antibiotics in IR of foot, ankle, lower leg or patella.

Costs and complications associated with transvenous lead reoperation in cardiac implantable electronic devices.

BACKGROUND: Cardiac implantable electronic device transvenous (TV) lead reoperations are projected to increase, and robust economic data are needed to assess the resulting financial impact and the cost-effectiveness of prevention and treatment strategies. This study estimates Medicare costs, and describes patterns of complications, in patients who underwent TV lead reoperation. METHODS AND RESULTS: Medicare data (2010-2014) were used to identify patients who underwent TV lead reoperation. Cumulative costs to Medicare, and rates of infection and mechanical complications were calculated from 180 days before, to 180 days after, lead reoperation. Multivariate analysis was used to estimate adjusted costs, and to examine the impact of complications on medical resource use and costs. There were 1691 patients, 63.2% of whom underwent inpatient lead reoperation. Overall, the mean age was 78.2 years, 39.6% were female, and 92.3% were white. The mean cumulative cost was $36 199 (95% confidence interval [CI], $31 864-$40 535) for TV lead repositioning, $27 701 (95% CI, $19 869-$35 534) for repair, and $54 442 (95% CI, $51 651-$57 233) for removal. Underlying infection was associated with increased odds of inpatient reoperation and of lead removal, as well as longer length of stay and higher costs. CONCLUSIONS: The economic consequences of TV lead reoperation are substantial. Strategies aimed at reducing reoperation, particularly lead removal, are likely to result in considerable cost offsets.

Cost and Outcomes of Implantable Cardiac Electronic Device Infections in Victoria, Australia.

BACKGROUND: Implantable cardiac electronic device (ICED) infections are associated with significant morbidity, mortality and cost. The aim of this study was to perform the first analysis for the cost of ICED infection in Australia. Secondary aims were to provide an update on the incidence, burden and outcomes of ICED infections and an analysis of the hospital ICD-10 codes used for ICED infection admissions. METHODS: We performed a retrospective study of ICED implantations and infections in the Barwon Health region (BH) and the state of Victoria (Vic) from January 2010 to December 2015 inclusive. RESULTS: Sensitivity of ICD-10 code T82.7 was 63.4% (95% CI 46.9-77.8) and specificity was 14.5% (95% CI 9.9-21.1). Infection rates were 1.4 admissions/100,000 persons/year (SD 0.7) in BH and estimated to be 7.9 admissions/100,000 persons/year (95% CI 6.8-9.0) in Vic. Average cost of infection was $670,334/year in BH and estimated to be $14,879,979/year in Vic. CONCLUSION: Rates of ICED infection are decreasing in Victoria. Infections are associated with significant morbidity and cost.

Reduced incidence and economic cost of hardware removal after ankle fracture surgery: a 20-year nationwide registry study.

Background and purpose - Open reduction and internal fixation (ORIF) is a treatment method for unstable ankle fractures. During recent years, scientific evidence has shed light on surgical indications as well as on hardware removal. We assessed the incidence and trends of hardware removal procedures following ORIF of ankle fractures.Patients and methods - The study covered all patients 18 years of age and older who had an ankle fracture treated with ORIF in Finland between the years 1997 and 2016. Patient data were obtained from the Finnish National Hospital Discharge Register.Results - 68,865 patients had an ankle fracture treated with ORIF in Finland during the 20-year study period between 1997 and 2016. A hardware removal procedure was performed on 27% of patients (n = 18,648). The incidence of hardware removal procedures after ankle fracture decreased from 31 (95% CI 29-32) per 100,000 person-years in the highest year 2001 (n = 1,247) to 13 (CI 12-14) per 100,000 person-years in 2016 (n = 593). Moreover, the proportion and number of removal operations performed within the first 3 months also decreased. The costs of removal procedures decreased from approximately €994,000 in 2001 to €472,600 in 2016.Interpretation - Removal of hardware after ankle surgery (ORIF) is a common operation with substantial costs. However, the incidence and cost of removals decreased during the study period, with a particular decrease in hardware removal operations within 3 months.

Potential cost-effectiveness of wearable cardioverter-defibrillator for patients with implantable cardioverter-defibrillator explant in a high-income city of China.

INTRODUCTION: Wearable cardioverter-defibrillator (WCD) is recommended for patients with implantable cardioverter-defibrillator (ICD) removal. This study aimed to investigate the potential cost-effectiveness of WCD for patients with ICD explant in a high-income city of China. METHODS AND RESULTS: A 5-year decision-analytic model was developed to simulate outcomes of three strategies during the period between ICD explant and reimplantation: discharge-to-home without WCD (home group), discharge-to-home with WCD (WCD group), and stay-in-hospital (hospital group). Outcome measures were mortality rates (during the period between ICD explant and reimplantation), direct medical costs, quality-adjusted life years (QALYs), and incremental cost per QALY saved (ICER). Model inputs were derived from literature and public data. Base-case analysis was performed at four cost levels of WCD. Robustness of model results was examined by sensitivity analyses. In base-case analysis, the 8-week mortality rates of WCD, hospital, and home groups were 7.3%, 8.1%, and 9.4%, respectively. WCD group gained the highest QALYs (3.0990 QALYs), followed by hospital group (3.0553 QALYs) and home group (3.0132 QALYs). The WCD group was the cost-effective option with ICERs less than willingness-to-pay (WTP) threshold (57 315 USD/QALY) at WCD daily cost ≤USD48. In probabilistic sensitivity analysis, the WCD group at daily cost of USD24, USD48, USD72, and USD96 were cost-effective in 100%, 94.16%, 22.08%, and 0.16% of 10 000 Monte Carlo simulations, respectively. CONCLUSIONS: Use of WCD during the period between ICD explant and reimplantation is likely to save life and gain higher QALYs. Cost-effectiveness of WCD is highly subject to the daily cost of WCD in China.

Real-world costs of transvenous lead extraction: the challenge for reimbursement.

AIMS: Transvenous lead extraction is challenging, often requiring specialist equipment and prolonged hospital admission. A single tariff or itemized costs may be available for reimbursement. Due to limited data relating to the costs of transvenous extraction, it is unclear whether either form of reimbursement is adequate. We aim to describe accurately the total real-world costs of managing patients undergoing transvenous extraction at a single, large centre. We further aim to consider the additional costs of device reimplantation. METHODS AND RESULTS: At a single UK extraction centre, a retrospective, patient level service line analysis was undertaken, during a complete financial year. Seventy-four patients required transvenous extraction (47 infected and 27 non-infected; 156 leads). Sixty-nine procedures (93%) were performed under general anaesthesia, with a median time in theatre of 95 min [interquartile range (IQR) 71-120]. Specialist extraction tools were required for 130 leads (83%). The median hospitalization duration was 3 days (IQR 1-8). The mean cost of extraction was £9228 (±4099); infected £10 727 (±4178) and non-infected £6619 (±2269). With the additional costs of device reimplantation, the overall mean cost rose to £17 574 (±12 882); infected £22 615 (±13 343) and non-infected £8801 (±5007). At the time of this study, the UK NHS tariff was £2530 for elective and £4764 for non-elective extraction, covering barely half of the real costs. CONCLUSION: We demonstrated a substantial difference between the real-world cost of extraction and the UK NHS tariff. Extracting centres should scrutinize their practice, including the timing of reimplantation.

Effect of cost on early removal of contraceptive implants: a prospective cohort study.

OBJECTIVES: To evaluate the effect of the cost of subdermal etonogestrel implant (SEI) on the continuation rate one year after insertion, and to assess the reasons given by users to remove the implant before the expiration date. METHODS: Prospective cohort study conducted among 265 women who chose the SEI as a contraceptive method in a sexual and reproductive health center in the eastern region of Spain, between October/2012 and October/2017. The sample was divided into two cohorts depending on the cost of the implant for the user (free-of-charge or requiring partial payment). Kaplan-Meier survival curves were used to compare the cumulative removal rates of free implants with partially paid implants within the first year of insertion. Cox proportional hazards models were used to control for confounders. RESULTS: After adjusting for confounders, no significant associations were found between the cost of the implant and its removal within a year of insertion. No significant associations were found in the reasons given for implant removal and for the duration of implant use. CONCLUSIONS: Cost was not associated with SEI continuation rates within the first year of use. No other significant variables were found to explain implant removal within one year of use.

[Economic Analysis of the Costs of Hospital Stay of Patients with Infection as a Complication of Total Replacements - Part 2: Total Hip Arthroplasty]. / Ekonomická analýza nákladu na hospitalizaci pacientu s infekcní komplikací totální náhrady - 2. cást: totální náhrada kycelního kloubu.

PURPOSE OF THE STUDY The study aims to quantify the costs of a hospital stay of patients with periprosthetic joint infection after total hip arthroplasty throughout the period of treatment. MATERIAL AND METHODS The group included patients who have been treated at our department for infection as a complication of total hip replacement since 1 January 2011, who have been provided with treatment (including complications) exclusively at the departments of Nemocnice Ceské Budejovice, a.s. and whose treatment can be considered completed in 2019. The patients were included in the study regardless of the type of infection and method of treatment. The group consisted of 36 patients (16 men and 20 women). There were 3 cases of early postoperative infection, 14 cases of late postoperative infection and 19 cases of hematogenous infection. The group includes 8 patients treated by a one-stage reimplantation, 19 patients managed by a two-stage reimplantation, 6 patients treated by a revision surgery with implant retention, and 3 patients in whom only the implant removal was possible. In selected patients, all the reported points for all the hospital stays and costs incurred on a separately charged material were ascertained and the final sum was compared with the reimbursement obtained by the hospital in the DRG system valid for the respective year of treatment. The total costs were analysed and also an analysis by type of infection and method of treatment was carried out. RESULTS The average costs of managing infection as a complication of total hip arthroplasty at our department amounted to CZK 320 065 (CZK 56 995 - CZK 953 614), the reimbursement in respect of the monitored cases in the DRG system equalled CZK 220 503 (CZK 89 149 - CZK 589 974). The aforementioned suggests that the average loss per treated patient is CZK 99 562 (CZK + 63 372 - CZK -428 499). DISCUSION Care associated with infections as a complication of total hip arthroplasty is very costly and these costs are not fully covered by the reimbursement from the health insurance companies. In the Czech Republic, these costs have not been quantified as yet, therefore it is only possible to compare the costs with international publications arriving at similar conclusions and with own monitoring of the costs of periprosthetic joint infections after total hip arthroplasty. The most economically efficient is the one-stage replacement which, however, is not suitable for all the patients, and the two-stage reimplantation continues to be the gold standard. In our study, the most expensive was found to be the treatment of periprosthetic joint infection after total hip arthroplasty, in which also the highest financial loss is reported. CONCLUSIONS Due to the very high costs of treatment for periprosthetic joint infections after total hip arthroplasty, it is necessary to exert maximum efforts to prevent periprosthetic joint infections and to consider a change in the method of financing, particularly in centres to which patients are referred from other centres in order to make this treatment economically viable. Key words:total hip arthroplasty, PJI - periprosthetic joint infection, economic analysis.

The burden of hardware removal in ankle fractures: How common is it, why do we do it and what is the cost? A ten-year review.

BACKGROUND: Ankle fractures account for 9% of all fractures and 40% require surgical management. The ankle is the most common site of hardware removal. The purpose of our study was to investigate the incidence, indication and economic cost associated with removal of hardware from the ankle. METHODS: We conducted a ten-year retrospective review of 1482 patients treated by open reduction internal fixation for an unstable ankle fracture. Skeletally immature patients were excluded. Data collected was cross referenced from patient medical records, the radiological and electronic patient database. The casemix and hospital inpatient enquiry system (HIPE) were used to calculate costs. RESULTS: The mean age was 39.9 years with 53.6% male. 185 patients (12.5%) underwent hardware removal with unplanned removal performed in 6% of cases. The average cost of removal was €1113. CONCLUSION: Removal of hardware continues to be a common operation with significant costs to all involved. More than one in 10 patients underwent future removal of hardware. LEVEL OF EVIDENCE: Level 3.

Outcomes and Direct Costs of Inferior Vena Cava Filter Placement and Retrieval within the IR and Surgical Settings.

PURPOSE: To compare the outcomes and costs of inferior vena cava (IVC) filter placement and retrieval in the interventional radiology (IR) and surgical departments at a tertiary-care center. MATERIALS AND METHODS: Retrospective review was performed of 142 sequential outpatient IVC filter placements and 244 retrievals performed in the IR suite and operating room (OR) from 2013 to 2016. Patient demographic data, procedural characteristics, outcomes, and direct costs were compared between cohorts. RESULTS: Technical success rates of 100% were achieved for both IR and OR filter placements, and 98% of filters were successfully retrieved by IR means, compared with 83% in the OR (P < .01). Fluoroscopy time was similar for IR and OR filter insertions, but IR retrievals required half the fluoroscopy time, with an average of 9 minutes vs 18 minutes in the OR (P = .02). There was no significant difference between cohorts in the incidences of complications for filter retrievals, but more postprocedural complications were observed for OR placements (8%) vs IR placements (1%; P = .05). The most severe complication occurred during an OR filter retrieval, resulting in entanglement of the snare device and conversion to an emergent open filter removal by vascular surgery. Direct costs were approximately 20% higher for OR vs IR IVC filter placements ($2,246 vs $2,671; P = .01). CONCLUSIONS: Filter placements are equally successfully performed in IR and OR settings, but OR patients experienced significantly higher postprocedural complication rates and incurred higher costs. In contrast, higher technical success rates and shorter fluoroscopy times were observed for IR filter retrievals compared with those performed in the OR.

Infections and associated costs following cardiovascular implantable electronic device implantations: a nationwide cohort study.

Aims: This study assessed the contemporary occurrence of cardiac device infections (CDIs) following implantation in French hospitals and estimated associated costs. Methods and Results: A retrospective analysis was conducted on the French National Hospital Database (PMSI). Patients with a record of de novo cardiac implantable electronic device (CIED) implantation or replacement interventions in France in 2012 were identified and followed until the end of 2015. Cardiac device infections (CDIs) were identified based on coding using the French classification for procedures [Classification Commune des Actes Médicaux (CCAM)] and International Classification of Diseases (ICD-10). Associated costs were estimated based on direct costs from the perspective of the French social security system. In total 78 267 CIED patients (72% de novo implants) were identified (15% defibrillators; 84% pacemakers). The 36-month infection rate associated with de novo defibrillator-only implants, as well as for cardiac resynchronisation therapy - defibrillators (CRT-Ds) was 1.6%. The CDI risk was 2.9% and 3.9% for replacement ICDs and CRT-Ds. Infection rates were lower for de novo single-chamber pacemaker (SCP)/dual-chamber pacemaker (DCP) (0.5%) and cardiac resynchronisation therapy - pacemaker (CRT-P) implants (1.0%), while for replacement procedures the risk increased to 1.4% (SCP/DCP) and 1.3% (CRT-P). Mean infection-related costs over 24 months were €20 623 and €23 234 for CDIs associated with replacement and de novo procedures, and overall costs were not significantly different between pacemaker and defibrillator patients. Conclusion: Cardiac device infections in France are associated with substantial costs, when considering inpatient hospitalizations. Strategies to minimize the rate of CIED infection should be a priority for health care providers and payers.

Analysis of cost of component replacement versus entire device replacement during artificial urinary sphincter revision surgery.

AIM: To identify the costs of replacing an entire malfunctioning AUS device versus an individual component at the time of device malfunction. METHODS: Decision analysis was performed by analyzing the costs associated with revising a malfunctioning artificial urinary sphincter using one of two techniques: either individual or entire device replacement. Costs were determined by including actual institutional costs. Model assumptions were based on a summary of published literature and were created based on a time horizon of 0-5 years since the original, primary AUS was placed, and models were created for malfunction of each individual component. Sensitivity analysis was done adjusting for costs of the device and failure rates. RESULTS: Total costs to replace an individual component were $8330 for the pump, $7611 for the cuff, and $5599 for the balloon, while entire device replacement cost $15 069. Over a 5-year time horizon the cost per patient for replacement of a balloon, pump, or cuff were $14 407, $17 491, and $15 212, respectively, versus $18 001 if the entire device was replaced. To be less costly to replace the entire device, balloon, pump, and cuff failure rates would need to be >55%, >25%, or >37.5% during the first 2 years after placement. CONCLUSION: In the event of failure of the artificial urinary sphincter, cost analysis demonstrates that removal and replacement of the entire device is more expensive than replacement of a malfunctioning component at any point up to 5 years after initial AUS placement.

Implantable cardioverter-defibrillator therapy in Australia, 2002-2015.

OBJECTIVES: To quantify the number of implantable cardioverter-defibrillator (ICD) procedures in Australia by year, patient age and sex, and to estimate age group-specific population rates and the associated costs. Design, setting: Retrospective observational study; analysis of Australian National Hospital Morbidity Database hospital procedures data. PARTICIPANTS: Patients with an ICD insertion, replacement, adjustment, or removal procedure code, July 2002 - June 2015. MAIN OUTCOME MEASURES: Number of ICD procedures by procedure year, patient age (0-34, 35-69, 70 years or more) and sex; age group-specific population procedure rates; number of procedures associated with complications. RESULTS: The number of ICD procedures increased from 1844 in 2002-03 to 6504 in 2014-15; more than 75% of procedures were in men. In 2014-15, the ICD insertion rate for people aged 70 years or more was 78.1 per 100 000 population, 22 per 100 000 for those aged 35-69 years, and 1.40 per 100 000 people under 35. The reported complication rate decreased from 45% in 2002-03 to 19% in 2014-15, partly because of a change in the coding of complications. The number of removals corresponded to at least 4% of the number of insertions each year. The aggregate cost of hospitalisations with an ICD procedure during 2011-14 was $445 644 566. CONCLUSION: ICD procedures are becoming more frequent in Australia, particularly in people aged 70 or more. Patterns of care associated with ICD therapy, particularly patient- and hospital-related factors associated with adverse events, should be investigated to better understand and improve patient outcomes.

Factors Associated With Removal of Urinary Catheters After Surgery.

Publicly available data from the Centers for Medicaid & Medicare Services were used to analyze factors associated with removal of the urinary catheter within 48 hours after surgery in 59 Massachusetts hospitals. Three factors explained 36% of the variance in postoperative urinary catheter removal: fewer falls per 1000 discharges, better nurse-patient communication, and higher percentage of Medicare patients. Timely urinary catheter removal was significantly greater in hospitals with more licensed nursing hours per patient day.
