Utilizing time-driven activity-based costing to determine open radical cystectomy and ileal conduit surgical episode cost drivers.

OBJECTIVES: Patients undergoing radical cystectomy represent a particularly resource-intensive patient population. Time-driven activity based costing (TDABC) assigns time to events and then costs are based on the people involved in providing care for specific events. To determine the major cost drivers of radical cystectomy care we used a TDABC analysis for the cystectomy care pathway. SUBJECTS AND METHODS: We retrospectively reviewed a random sample of 100 patients out of 717 eligible patients undergoing open radical cystectomy and ileal conduit for bladder cancer at our institution between 2012 and 2015. We defined the cycle of care as beginning at the preoperative clinic visit and ending with the 90-day postoperative clinic visit. TDABC was carried out with construction of detailed process maps. Capacity cost rates were calculated and the care cycle was divided into 3 phases: surgical, inpatient, and readmissions. Costs were normalized to the lowest cost driver within the cohort. RESULTS: The mean length of stay was 6.9 days. Total inpatient care was the main driver of cost for radical cystectomy making up 32% of the total costs. Inpatient costs were mainly driven by inpatient staff care (76%). Readmissions were responsible for 29% of costs. Surgery was 31% of the costs, with the majority derived from operating room staff costs (65%). CONCLUSION: The major driver of cost in a radical cystectomy pathway is the inpatient stay, closely followed by operating room costs. Surgical costs, inpatient care and readmissions all remain significant sources of expense for cystectomy and efforts to reduce cystectomy costs should be focused in these areas.

Hospitalisation and readmission costs after radical cystectomy in a nationally representative sample: does urinary reconstruction matter?

OBJECTIVE: To investigate the impact of continent urinary diversion on readmissions and hospital costs in a nationally representative sample of radical cystectomies (RCs) performed in the USA. PATIENTS AND METHODS: The 2010-2014 Nationwide Readmissions Database was queried for patients with a diagnosis of bladder cancer who underwent RC. We identified patients undergoing continent (neobladder or continent cutaneous reservoir) or incontinent (ileal conduit) diversions. Multivariable logistic regression models were used to identify predictors of 90-day readmission, prolonged length of stay, and total hospital costs. RESULTS: Amongst 21 126 patients identified, 19 437 (92.0%) underwent incontinent diversion and 1 689 (8.0%) had a continent diversion created. Continent diversion patients were younger, healthier, and treated at high-volume metropolitan centres. Continent diversions resulted in fewer in-hospital complications (37.3% vs 42.5%, P = 0.02) but led to more 90-day readmissions (46.5% vs 39.6%, P = 0.004). In addition, continent diversion patients were more often readmitted for infectious complications (38.7% vs 29.4%, P = 0.004) and genitourinary complications (18.5% vs 13.0%, P = 0.01). On multivariable logistic regression, patients with a continent diversion were more likely to be readmitted within 90 days (odds ratio [OR] 1.55, 95% confidence interval [CI]: 1.28, 1.88) and have increased hospital costs during initial hospitalisation (OR 1.99, 95% CI: 1.52, 2.61). Continent diversion led to a $4 617 (American dollars) increase in initial hospital costs ($36 640 vs $32 023, P < 0.001), which was maintained at 30 days ($48 621 vs $44 231, P < 0.001) and at 90 days ($56 380 vs $52 820, P < 0.001). CONCLUSION: In a nationally representative sample of RCs performed in the USA, continent urinary diversion led to more frequent readmissions and increased hospital costs. Interventions designed to address specific outpatient issues with continent diversions can potentially lead to a significant decrease in readmissions and associated hospital costs.

Management of Ureteroenteric Stricture: Predictive Modeling to Compare Cost.

BACKGROUND: Ureteroenteric stricture occurs in as many as 15% of patients after cystectomy with urinary diversion. First-line management is typically percutaneous nephrostomy (PCN) drainage. We sought to compare costs of a urologic approach of retrograde stenting through flexible endoscopy and an interventional radiology (IR) approach of PCN and antegrade stenting using predictive modeling. The purpose of this study is to inform best practice for initial stricture management based on existing literature regardless of the benign stricture rate following radical cystectomy. Our hypothesis is that initial management by a urologist may be superior to IR management. MATERIALS AND METHODS: The primary outcome measure was cost based on 2015 Medicare reimbursement rates by Current Procedural Technology codes with a secondary endpoint of number of procedures a patient undergoes. We developed a simulation model to replicate the experience of stricture patients. The model describes three arms: urologic management with retrograde stent placement, sequential management by IR, and single-stage IR management. We simulated 10,000 patients through the model with the percentage of patients pursuing each treatment arm and success rates chosen based on a review of relevant literature and clinic experience. RESULTS: The average cost of urologic management is $703.23 compared with the average cost of $838.09 for patients using radiologic management. Within radiologic management, the average cost is $862.98 for sequential IR management and $639.44 for single-stage IR management. Patients would undergo an average of 2.53 procedures for those patients initially sent to urology and 2.91 procedures for those sent to radiology. For sequential IR, the average is 3.02 procedures, and for single-stage IR, it is 2.03 procedures. From a cost perspective, the success rate at which retrograde stent placement becomes worth attempting is 35%. If radiologic management is attempted initially, sequential IR management represents a cost-conscious option that limits the total number of procedures. CONCLUSION: The disparity in cost between IR and urologic management of ureteral stricture provides a rationale for rural practices that may not have immediate access to IR to manage the patient.

Totally intracorporeal robot-assisted radical cystectomy: optimizing total outcomes.

We performed a systematic literature review to assess the current status of a totally intracorporeal robot-assisted radical cystectomy (RARC) approach. The current 'gold standard' for radical cystectomy remains open radical cystectomy. RARC has lagged behind robot-assisted prostatectomy in terms of adoption and perceived patient benefit, but there are indications that this is now changing. There have been several recently published large series of RARC, both with extracorporeal and with intracorporeal urinary diversions. The present review focuses on the totally intracorporeal approach. Radical cystectomy is complex surgery with several important outcome measures, including oncological and functional outcomes, complication rates, patient recovery and cost implications. We aim to answer the question of whether there are advantages to a totally intracorporeal robotic approach or whether we are simply making an already complex procedure more challenging with an associated increase in complication rates. We review the current status of both oncological and functional outcomes of totally intracorporeal RARC compared with standard RARC with extraperitoneal urinary diversion and with open radical cystectomy, and assess the associated short- and long-term complication rates. We also review aspects in training and research that have affected the uptake of RARC. Additionally we evaluate how current technology is contributing to the future development of this surgical technique.

What about conventional laparoscopic radical cystectomy? Cost-analysis of open versus laparoscopic radical cystectomy.

PURPOSE: To assess direct healthcare costs for open radical cystectomy (ORC) vs laparoscopic radical cystectomy (LRC) with ileal conduit. PATIENTS AND METHODS: A series of 44 and 42 patients undergoing ORC and LRC with ileal conduit were retrospectively analyzed at a single institution from January 2005 to January 2012. The ORC and LRC procedures were performed by two independent surgical teams; there was no selection in patients. Data on patient demographics, perioperative outcome parameters, complications, and readmissions were gathered retrospectively in the ORC series and prospectively in the LRC series. Direct healthcare costs were evaluated for operating room occupation, disposable surgical equipment, blood transfusions, hospital stay according to intensity of care, and readmission days. RESULTS: Mean and median evaluated total direct healthcare costs per patient did not differ significantly and were 17,534€ and 16,511€ in the LRC group and 22,284€ and 15,909€ in the ORC group. Excess costs for disposable surgical equipment and operating room occupation within the LRC group were compensated for as a result of shorter hospital stay, lower number of blood transfusions, and intensive-care admissions. Minor and major complication rates were comparable between groups. CONCLUSION: Within our series, LRC is a cost neutral minimally invasive alternative to ORC without comprising quality of care and with beneficial perioperative outcomes.

Decision analysis for economic evaluation of the management of chronic obstructive uropathy.

OBJECTIVES: To test which is the best treatment for chronic obstructive uropathy: urinary diversion using a conventional double-J ureteral stent or the metal thermo-expandable MemokathTM 051 prosthesis. METHODS: We collected cost data of the insertion of a double-J stent taking into account preoperative and postoperative visits and surgery. Structural, medical, consumables and the prosthesis costs were considered. The estimated survival of the patient, number of spare stents and cost of each therapeutic measure were computed. Then, a simulation of the cost of inserting a MemokathTM 051 prosthesis was conducted, based on data of ureteral catheterization. We performed a decision tree and Cost Effectiveness economic analysis to measure the effectiveness of both health interventions. RESULTS: Cost data of each procedure were: 1275.44 € for the double J catheter in a program of day case surgery (DCS), 4865.16 € for the metal thermo-expandable prosthesis as DCS, and 1424.52€for the double J stent with 1 day admission and 5014.24 € for the prosthesis with 1 day admission. The cost difference between ureteral stent and metal thermo-expandable prosthesis is 3589.72 € per treatment for the ureteral stent as DCS. CONCLUSIONS: Despite its high initial cost, the metal thermo-expandable prosthesis potentially offers economic advantages over the conventional double-J ureteral stent in the treatment of long evolution ureteral obstruction. After the third change of double-J stent, and if the patient survival is long enough, the metal prosthesis as DCS should be the most cost effective option.

Cost-analysis comparison of robot-assisted laparoscopic radical cystectomy (RC) vs open RC.

OBJECTIVE: • To systematically review and compare the economic burden of open radical cystectomy (ORC) vs robot-assisted laparoscopic radical cystectomy (RALRC) with pelvic lymph node dissection and urinary diversion. PATIENTS AND METHODS: • A Medline search was conducted to identify English language articles regarding RC with urinary diversion. The resulting articles were then further restricted by the terms 'laparoscopic', 'robotic', or 'robotic-assisted'.In all, three articles were identified. • Data from each of these articles were then collected on cost performance in addition to relevant clinical variables, such as length of stay (LOS), operative duration, and complication rates. • When possible, data were subdivided by ileal conduit (IC), continent cutaneous diversion (CCD), and orthotopic neobladder (ON) subgroups. • Direct costs resulting from ORC or RALRC with accompanying hospitalization were identified. The indirect costs of complications were considered. RESULTS: • Despite an increased materials cost, RALRC was less expensive than ORC when the cost of complications was considered. • RALRC was less expensive than ORC for IC and CCD, but the cost advantage deteriorated for ON. • The largest cost drivers cited in the published data were LOS, operative durations, and daily hospitalizations costs. • RALRC demonstrated shorter LOS compared with ORC, although this effect was insufficient to offset the increased cost of robotic surgery. • Complications materially affected cost performance. CONCLUSIONS: • Despite an increased materials cost, RALRC can be more cost efficient than ORC as a treatment for bladder cancer when the impact of complications are considered. • This effect is most pronounced for patients undergoing IC.

Cost-effectiveness of open versus laparoscopic versus robotic-assisted laparoscopic cystectomy and urinary diversion.

PURPOSE OF REVIEW: To provide insight into the recently published cost comparisons in the context of open, laparoscopic, and robotic-assisted laparoscopic radical cystectomy and to demonstrate the complexity of such economic analyses. RECENT FINDINGS: Most economic evaluations are from a hospital perspective and summarize short-term perioperative therapeutic costs. However, the contributing factors (e.g. study design, included variables, robotic amortization plan, supply contract, surgical volume, surgeons' experience, etc.) vary substantially between the institutions. In addition, a real cost-effective analysis considering cost per quality-adjusted life-year gained is not feasible because of the lack of long-term oncologic and functional outcome data with the robotic procedure. On the basis of a modeled cost analysis using results from published series, robotic-assisted cystectomy was - with few exceptions - found to be more expensive when compared with the open approach. Immediate costs are affected most by operative time, followed by length of hospital stay, robotic supply, case volume, robotic cost, and transfusion rate. Any complication substantially impacts overall costs. SUMMARY: Economic cost evaluations are complex analyses influenced by numerous factors that hardly allow an interinstitutional comparison. Robotic-assisted cystectomy is constantly refined with many institutions being somewhere on their learning curve. Transparent reports of oncologic and functional outcome data from centers of expertise applying standardized methods will help to properly analyze the real long-term benefits of robotic surgery and successor technologies and prevent us from becoming slaves of successful marketing strategies.

The economics of robotic cystectomy: cost comparison of open versus robotic cystectomy.

OBJECTIVE: • To assess and compare the economic burden of open radical cystectomy (OC) vs robotic-assisted laparoscopic radical cystectomy (RC) with pelvic lymph node dissection and urinary diversion. PATIENTS AND METHODS: • A series of 103 and 83 consecutive patients undergoing OC and RC, respectively, were prospectively studied at a tertiary care institution from April 2002 to February 2009. • Data were collected on patient demographics, perioperative parameters and length of stay (LOS) in hospital. Cohorts were subdivided into ileal conduit (IC), continent cutaneous diversion (CCD) and orthotopic neobladder (ON) subgroups. • A linear cost model was created to simulate treatment with OC vs RC. Procedural costs were derived from the Medicare Resource Based Relative Value Scale. Materials costs were obtained from the respective suppliers. The indirect costs of complications were considered. • Sensitivity analyses were performed. RESULTS: • Despite a higher cost of materials, RC was less expensive than OC for IC and CCD, although the cost advantage deteriorated for ON. • The per-case costs of RC with IC, CCD and ON were $20,659, $22,102 and $22,685, respectively, compared to $25,505, $22,697 and $20,719 for their OC counterparts. • The largest cost driver in the study was LOS in hospital. • RC showed a shorter LOS compared to OC, although this effect was insufficient to offset the higher cost of robotic surgery. • Complications materially affected cost performance. CONCLUSIONS: • Despite a higher cost of materials, RC can be more cost efficient than OC as a treatment for bladder cancer at a high-volume, tertiary care referral centre, particularly with IC. • Complications significantly impact cost performance.

[Representation of cystectomy and urinary diversion in the G-DRG system 2010: an example for the complexity of the reimbursement system]. / Kodierung der Zystektomie im DRG-System 2010 : Ein Beispiel für die Komplexität des Abrechnungssystems.

Cystectomy and urinary diversion is an excellent example for the growing complexity of the G-DRG (German diagnosis-related groups) system. Based on different diagnoses (malignant tumor of the urinary tract, benign disease of the urinary tract, malignant tumor of the female genital tract, or malignant tumor of the male genital tract), identical cases may lead to very different codes, resulting in even more differences in reimbursement.

Accessories or necessities? Exploring consensus on usage of stoma accessories.

Usage and opinion of accessory products in stoma care vary enormously. The aim of this study was to identify what constitutes an accessory product and to find out whether there is any standardization regarding their recommendation. Views of both patients and stoma nurses were examined. Patients identify accessory products as being necessary both physically and psychologically in improving their quality of life. While stoma nurses identify that the psychological effects of having a stoma should never be underestimated, there is still concern regarding the cost of recommending these products and their clinical necessity. It would appear that clinical necessity is based on nurses' opinions and is not always evidence or research based. Since accessory products have been shown to be essential to many patients with a stoma, should stoma nurses be more empathetic when considering their recommendation?

Stoma care nursing management: cost implications in community care.

Successfully rehabilitating the stoma patient in the community means continuing the care provided by the hospital and preparing the patient for this new phase of life. It is well documented that this transition from hospital to home can often be a difficult time for the stoma patient and that home visits and ongoing support from the district nursing team are needed for many patients in the long term. This article aims to help community nurses understand the needs of the stoma patient in their homes and looks at the current situation, including costs, of supplying stoma appliances in the community.

[Adult ostomy patients in the city of São Paulo: a study of specialized equipment costs]. / Estomizado adulto no município de São Paulo: um estudo sobre o custo de equipamentos especializados.

This study was aimed at analyzing the monthly cost of the use of specialized equipment by ostomy patients. It is a retrospective study carried out at two Outpatient Health Centers in São Paulo. The data were collected in 635 records of adult ostomy patients assisted in June of 2005. For the costs, the data were obtained in electronic databases and official publications from the State of São Paulo Health Secretary, and the results were submitted to the Kolmogorov-Smirnov, Mann-Whitney, Kruskal-Wallis, Bonferroni and Spearman tests. Most of the individuals were female (51%), aged > or = 60 years, with temporary colostomy (64.5%). The average monthly cost was US$ 51.0 per patient, higher for cancer urostomy patients with permanent stomas, with neoplasia in the urinary tract and assisted by the service with a therapist nurse. Statistically significant correlation between the monthly cost and the time with stoma was found. This study has contributed for the assessment of the cost of ostomy patients in the State of São Paulo.

A cost comparison of laparoscopic versus open radical cystoprostatectomy and orthotopic ileal neobladder at a single institution.

AIM OF THE STUDY: To evaluate the specific cost components in two similar groups of patients who underwent laparoscopic or open radical cystoprostatectomy with orthotopic ileal neobladder at our Institution. METHODS: Between November 2000 and July 2004, 20 men with transitional cell carcinoma of the bladder underwent laparoscopic (group 1) or open (group 2) radical cystoprostatectomy with orthotopic ileal neobladder. We evaluated the costs of hospital stay, surgical consumables and operating room occupation. At our Institution one day of hospital stay costs Euro 625 while one hour of operating room costs Euro 520 (professional fees included). RESULTS: Hospital stay and operating room occupation in group 1 and 2 were statistically different (respectively 395.5 versus 275 min and 10.5 versus 18.9 days). Surgical consumables cost Euro 637 for patients in group 1 versus Euro 270 for patients in group 2. With the considered issues, at our Institution laparoscopic radical cystoprostatectomy costs Euro 10,626 whereas open radical cystoprostatectomy costs Euro 14,465. CONCLUSIONS: Laparoscopic radical cystoprostatectomy seems associated with a shorter hospital stay and with a reduction of costs if compared to the open approach.

Two-surgeon versus single-surgeon radical cystectomy and urinary diversion: impact on patient outcomes and costs.

OBJECTIVES: To examine the difference in charges and outcomes between patients who underwent radical cystectomy and urinary diversion by a team of two surgeons versus a single surgeon. METHODS: A total of 63 patients with bladder cancer who underwent the procedures were retrospectively analyzed. Two surgeons sequentially performed the cystectomy and ileal conduit (IC, n = 17) or neobladder (NBL, n = 18) or a single surgeon performed both the cystectomy and IC (n = 21) or NBL (n = 7). Procedure-related charges, hospital charges, operating room time, length of stay, and complications were compared between the two groups. RESULTS: For the IC patients, the two-surgeon team had 60% greater mean surgeon charges (P <0.0001), 23% lower mean anesthesia charges (P <0.0001), 121 minutes shorter operating room time (P = 0.001), and 30% lower operating room charges (P = 0.001). For the NBL patients, the two-surgeon team had 32% greater surgeon charges (P <0.0001), 22% lower anesthesia charges (P = 0.003), 149 minutes shorter operating room time (P <0.0001), and 41% less operating room charges (P <0.0001). No differences were found in total hospital charges. The NBL patients who underwent surgery by two surgeons had a longer length of stay (P = 0.008). No differences were found in complications between the groups. CONCLUSIONS: For IC patients, our data showed no differences in the average overall charges, whether a two-surgeon team or a single surgeon performed the procedure. Additional reductions in hospital charges could offset the greater physician charges in the NBL patients and allow full realization of the benefit from the shorter operative time with the two-surgeon team.

Costs of radical cystectomy.

OBJECTIVE: The total costs of radical cystectomy comprise a significant part of the total costs of bladder cancer treatment. The aims of this study were to determine the costs of cystectomy, with and without complications, and to investigate related prognostic factors. MATERIAL AND METHODS: The clinical records and relevant economic files of 70 consecutive patients operated on between 1994 and 1998 were studied. Uni- and multivariate analyses were performed on 22 variables of possible prognostic significance to high total costs. RESULTS: The total (median) costs for 53 uncomplicated and 17 complicated cystectomies were 181,096 and 290,625 SEK, respectively. The preoperative variables (patient characteristics) had no or minimal prognostic significance for high total costs. High peri-operative blood loss was the most important factor associated with high total hospital costs for radical cystectomy. CONCLUSIONS: Total costs may be very high for a cystectomy with complications. Peri-operative blood loss was the most important factor associated with high total hospital costs for radical cystectomy due to bladder cancer. If the amount of bleeding can be influenced then substantial reductions in the total costs of cystectomy would seem possible.
