Mesane kanserinde radikal sistektomi üriner diversiyon operasyonu yapılan hastalarda perioperatif parametrelerin değerlendirilmesi

Purpose: The aim of this study was to evaluate the effect of red blood cell transfusion and/or inotropic/vasopressor agent infusion during intraoperative and postoperative first 24-hour period on 30-day and one-year survival. Materials and Methods: In the final analysis, 133 patients who underwent radical cystectomy and urinary diversion surgery between November 2011 and January 2019 were included in this study. Perioperative anesthesia management early postoperative intensive care patient follow-ups were based on. Results: A statistically significant relationship was found between intraoperative red blood cell transfusion and one-year mortality rates. A statistically significant relationship was found between red blood cell transfusion in the intensive care unit and postoperative 30-day mortality rates. The relationship between vasopressor/inotrope agent infusion in intensive care unit and postoperative 30-day mortality was statistically significant. Conclusion: In radical cystectomy and urinary diversion, intraoperative red blood cell and/or inotrope/vasopressor drug administration, and red blood cell transfusion within first 24 postoperative hours in intensive care unit are associated with lower survival rates in both early and late periods. Future studies should focus on developing and implementing different strategies for perioperative blood management and maintenance of patient hemodynamics that may affect early and late outcomes.

Blood loss associated with radical cystectomy: a prospective, randomized study comparing Impact LigaSure vs. stapling device

OBJECTIVES

Radical cystectomy (RC) is associated with significant blood loss and transfusion requirement. We performed a prospective, randomized trial to compare blood loss, operative time, and cost using 2 different and commonly employed approaches to tissue ligation and division during RC: mechanical (stapler device) and electrosurgical (heat-sealing device).

METHODS AND MATERIALS

Eighty patients undergoing RC for urothelial bladder carcinoma were randomized to use of either an Endo GIA Stapler or Impact LigaSure device for tissue ligation and division. Primary outcomes were blood loss, operative time, and device costs. Data were analyzed with Wilcoxon rank sum test and Welch 2-sample t test.

RESULTS

There were no significant demographic or preoperative differences between the cohorts. Mean estimated blood loss was similar between the electrosurgical (687 ml) and stapler (708 ml) arms (P = 0.850). There were no significant differences between cohorts when comparing operative times or transfusion requirement. There was a significant increase in the mean number of adjunctive suture ligatures used in the stapling device arm (3.0 vs. 1.5, P = 0.047). Total device costs were significantly lower with the LigaSure compared with the GIA Stapler ($625.00 vs. $1490.10, P<0.001). There were no complications attributable to either device.

CONCLUSIONS

This prospective, randomized study demonstrates no significant difference in blood loss, transfusion requirement, or safety between mechanical vs. electrosurgical control of the vascular pedicles. The LigaSure device, however, is significantly less costly than the GIA Stapler and required fewer additional measures for hemostasis.

Early and late treatment‐related morbidity following radical cystectomy

OBJECTIVE

To evaluate treatment-related morbidity following cystectomy in a cohort of consecutive bladder cancer patients. The impact of age, comorbid condition, previous pelvic radiotherapy and type of urinary diversion was analysed.

MATERIAL AND METHODS

Between 1992 and 1998 the treatment-related early (<30 days after cystectomy) and late morbidity was recorded in 268 consecutive bladder cancer patients (median age 65 years) undergoing cystectomy and the following types of urinary diversion: ileal conduit, n = 195; orthotopic neobladder, n = 36; continent reservoir, n = 33; and ureterocutaneous diversion, n = 4. Twenty-four patients had received previous pelvic radiotherapy and 79 had pre-existing morbidity. The median follow-up period was 5.4 years.

RESULTS

The postoperative mortality rate was 2%. Age >70 years and pre-existing morbidity (especially cardiovascular disease) significantly increased the mortality rate. No relationship was found between early complication (57%) and re-exploration rates (17%) and either age, previous radiotherapy, pre-existing morbidity or type of urinary diversion. Patients undergoing orthotopic neobladder or continent reservoir had a significantly increased risk of calculus formation as well as cystectomy-related surgical procedures compared to patients undergoing ileal conduit. Age had a significant impact on vitamin B12 deficiency and renal deterioration, whereas previous pelvic irradiation significantly increased the probability of ureteroenteric stricture and lost renal function. Age and urinary diversion had no impact on hernia, ureteroenteric stricture or pyelonephritis.

CONCLUSION

The risk of treatment-related morbidity was high and careful patient selection before cystectomy seems important. The lack of standard criteria regarding how to report morbidity makes comparison with other studies difficult.

The Effects of Adjusting for Case Mix on Mortality and Length of Stay Following Radical Cystectomy

PURPOSE

Prior studies evaluating quality of care following radical cystectomy have been constrained by the use of retrospective reviews of single institutional series and limited ability to examine risk factors in a comprehensive manner. Characterization of these factors could enhance preoperative patient counseling and facilitate perioperative management, thereby improving the quality of patient care.

MATERIALS AND METHODS

The National Surgical Quality Improvement Project is a prospective quality management initiative at 123 Veterans Affairs Medical Centers nationwide. The project collects preoperative clinical and intraoperative data, and outcomes on a wide variety of surgical procedures from multiple surgical disciplines. Since 1991, 2,538 radical cystectomies have been captured by the National Surgical Quality Improvement Project. Modeling using logistic regression was performed to identify preoperative risk factors associated with mortality and prolonged length of stay (greater than 90th percentile) after radical cystectomy.

RESULTS

The 30 and 90-day mortality rates following cystectomy were 2.9% and 6.8%, respectively, and median hospital stay was 11 days (90th percentile 30). Robust preoperative factors associated with mortality and prolonged length of stay that uniformly increased risk were older patient age (OR 1.2 to 1.4), American Society of Anesthesiologists class 3 or greater (OR 1.5 to 3.3), dependent functional status (OR 1.7 to 2.0) and low serum albumin (OR 2.1 to 12.0).

CONCLUSIONS

A defined set of preoperative risk factors is independently associated with greater mortality and hospital stay following radical cystectomy. The breadth of these factors suggests that complex case mix adjustment is mandatory when comparing outcomes. Implementation of novel processes directed toward minimizing patient risk has the potential to improve outcomes following cystectomy.

A Critical Analysis of Perioperative Mortality From Radical Cystectomy

PURPOSE

Operative mortality from radical cystectomy has decreased as a result of improvements in surgical and anesthetic care. We reviewed the perioperative deaths from a large group of patients treated with radical cystectomy for primary bladder cancer.

MATERIALS AND METHODS

All perioperative mortalities from radical cystectomy were identified from a single high volume institution. The medical records were reviewed to assess the cause of death as well as possible contributing factors.

RESULTS

From August 1971 to December 2001, 1,359 patients with primary bladder cancer were treated with radical cystectomy and pelvic iliac lymphadenectomy at our institution. Of these patients, 27 (2%) died within 30 days of surgery or before discharge from hospital. Median patient age at surgery was 67 years (range 47 to 78) and males accounted for 81% of the patients. The median time to death was 28 days from cystectomy (range 0 to 80). Most deaths were cardiovascular related (including acute myocardial infarction, cerebrovascular accident, arterial thrombosis) or due to septic complications with resulting multi-organ system failure, followed by pulmonary embolism, hepatic failure and hemorrhage. Septic related mortality was most often associated with postoperative urine or bowel leak. While most deaths occurred before hospital discharge, 2 patients died at home due to a late pulmonary embolus. No association was seen between pathological stage or type of urinary diversion and mortality.

CONCLUSIONS

Perioperative mortality from radical cystectomy is low in this group of patients. Most deaths are due to cardiovascular or septic complications. Careful patient selection and meticulous surgical technique may help decrease the incidence of perioperative mortality.

Identifying risk factors for potentially avoidable complications following radical cystectomy

PURPOSE

Morbidity after radical cystectomy is common and associated with increased health care resource use. Accurate characterization of complications after cystectomy, associated patient specific risk factors, and perioperative processes of care are essential to directing changes in perioperative management that will reduce morbidity and improve the quality of patient care.

MATERIALS AND METHODS

The National Surgical Quality Improvement Program (NSQIP) is a prospective quality management initiative of 123 Veterans Affairs Medical Centers nationwide. The NSQIP collects clinical information, intraoperative data and outcomes on a wide variety of surgical procedures from multiple surgical disciplines. Since 1991, 2,538 radical cystectomy procedures have been captured by the NSQIP. Modeling using logistic regression was performed to identify patient specific risk factors and perioperative process measures associated with postoperative morbidity.

RESULTS

Of the 2,538 subjects at least 1 postoperative complication developed in 774 (30.5%). The most frequent complication was ileus (10%). Several factors were associated with the development of a complication, including age, dependent functional status, preoperative dyspnea, preoperative acute renal failure, chronic steroid use, preoperative alcohol consumption, American Society of Anesthesiology score, use of general anesthetic, operative time, intraoperative blood requirement and surgeon level of training.

CONCLUSIONS

Morbidity remains high after cystectomy with 30.5% of subjects experiencing at least 1 complication. Measurable patient specific risk factors and perioperative processes associated with postoperative morbidity following cystectomy are now delineated which allows for improved risk stratification, patient counseling, and the development of novel processes that may incrementally reduce risk and improve outcomes.

A CLINICAL PATHWAY FOR LAPAROSCOPIC PYELOPLASTY DECREASES LENGTH OF STAY

PURPOSE

Benefits of minimally invasive procedures include decreased hospitalization and recovery times. Decreased length of stay (LOS) improves hospital efficiency and decreases costs. However, decreasing the LOS at the expense of patient care and satisfaction is not acceptable. A clinical pathway (CP) with structured order sets and imaging was developed for patients undergoing laparoscopic pyeloplasty. This pathway includes a cascade of activities managed closely by the health care team. This study assesses the safety and patient satisfaction with this clinical pathway.

MATERIALS AND METHODS

We reviewed all adult pyeloplasties (39) completed laparoscopically since November 2001. All patients were managed according to the CP developed for the laparoscopic pyeloplasty procedure. The length of stay was measured in days. Patient satisfaction was assessed with a standardized questionnaire. Any readmissions or emergency room visits were documented.

RESULTS

The mean length of stay was 1.10 days. Of 39 patients 37 (94%) were discharged home on postoperative day 1. One patient with severe postoperative pain required intravenous analgesia. She had undergone complex upper tract reconstruction and stayed a total of 4 days. One patient, who had a previous failed endopyelotomy, remained 2 days for persistent nausea. No patients sought emergency room consultation and there were no readmissions. Of 39 patients 34 (87%) completed the questionnaire and satisfaction was high.

CONCLUSIONS

The implementation of a CP at our institution has standardized patient care in this population and decreased LOS in comparison to the literature. This improves bed use and hospital efficiency while maintaining a high degree of patient satisfaction. We conclude that with intensive patient care and education most patients undergoing laparoscopic pyeloplasty may be discharged home safely on postoperative day 1.

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.

ASSOCIATION BETWEEN VOLUME AND CHARGES FOR MOST FREQUENTLY PERFORMED AMBULATORY AND NONAMBULATORY SURGERY FOR BLADDER CANCER. IS MORE CHEAPER?

PURPOSE

We investigated the relationship between provider volume and charges for transurethral bladder tumor resection (TURBT) and radical cystectomy in patients with bladder cancer.

MATERIALS AND METHODS

The National Inpatient Sample (1988 to 1999) of the Health Care Utilization Project, and State Ambulatory Surgery Databases for Wisconsin and Florida (2000 data set) were used for analysis. All patients with bladder cancer who had undergone radical cystectomy or TURBT as the principal procedure were identified. Hospitals and surgeons were categorized into terciles of volume based on the average number performed per year. The average hospital charge per discharge/procedure corrected to 2000 levels was calculated. One-way ANOVA with the Bonferroni correction was used to compare charges between different volume levels.

RESULTS

A total of 13,498 patients who underwent radical cystectomy and 5,954 who underwent TURBT were included in the analysis. Charges for radical cystectomy were 5,648 USD lower at high volume hospitals than at low volume hospitals (p <0.001). High volume surgeons were 2,976 USD less expensive than low volume surgeons (p =0.054). For TURBT total hospital charges at high volume hospitals were 1,013 USD more than at low volume hospitals (p <0.0001), while average total hospital charges for procedures performed by high volume surgeons were 919 USD less compared to low volume surgeons (p <0.0001).

CONCLUSIONS

High risk inpatient procedures for bladder cancer such as cystectomy, which are more influenced by systems of care, are less expensive to perform at high volume centers. Lower risk ambulatory procedures for bladder cancer, such as TURBT, which are not influenced by systems of care, may be more cost efficiently performed by high volume surgeons at low volume centers.

Increased body mass index predicts increased blood loss during radical cystectomy

PURPOSE

Historically obesity has been thought to impact negatively patients undergoing surgery. We evaluated the impact of body mass index (BMI), an objective measure of obesity, on operative and perioperative outcomes in patients undergoing radical cystectomy.

MATERIAL AND METHODS

We reviewed the records of 304 consecutive patients who underwent radical cystectomy and urinary diversion between October 1995 and July 2000. Factors analyzed included BMI, clinical demographic characteristics, comorbidities, operative variables (eg estimated blood loss [EBL], transfusion requirement and operative time), length of stay and postoperative complications. Results were analyzed using the nonpaired heteroscedastic Student t test assuming unequal variances to determine statistical significance.

RESULTS

Of the patients 61% were overweight or obese (BMI 25 or greater). BMI did not correlate with type of urinary diversion, gender or race. On univariate analysis the preoperative variables age, American Society of Anesthesiologists score and BMI correlated with EBL. However, on multivariate analysis BMI was the only preoperative or operative variable that significantly correlated with EBL (p = 0.01). Mean EBL in patients with a normal BMI (less than 25) was 595 ml compared to the mean EBL for overweight and obese patients (25 or greater of 811 ml (p <0.001). However, BMI did not correlate with the complication rate or hospital stay.

CONCLUSIONS

On multivariate analysis considering preoperative and operative variables BMI was the only preoperative variable that predicted increased blood loss. Despite this finding overweight or obese patients in this series did not have a higher complication rate or longer hospital stay.

Decreasing blood loss in patients treated with radical cystectomy: a prospective randomizes trial using a new stapling device

PURPOSE

Radical cystectomy has been associated with significant blood loss and the need for heterologous transfusion. We investigated the potential decrease in blood loss and/or in transfusion requirement using a new stapling device compared with the traditional suture ligation technique.

MATERIALS AND METHODS

We prospectively examined 70 patients with urothelial carcinoma who were scheduled for radical cystectomy. Each patient was randomized to traditional suture ligation or the Compact Flex Articulating Linear Cutter (Ethicon Endo-Surgery, Cincinnati, Ohio) stapling device. The 2 groups were prospectively compared with respect to estimated blood loss, transfusion requirement, operative time and complications.

RESULTS

The groups were equivalent in terms of demographic and clinical variables, indicating that randomization produced 2 comparable groups. The stapler group had significantly lower estimated blood loss during cystectomy (p = 0.007) and during the whole procedure (p = 0.02). This group also required fewer transfusions (p = 0.006) and fewer mean units transfused (p = 0.003). The overall transfusion rate was 20% (14 of 70 cases). All patients in the stapler group had lower estimated blood loss and transfusion requirements. There was no statistical difference in time needed for bladder removal (p = 0.91) or total operative time (p = 0.17). No complications were attributable to the stapler device.

CONCLUSIONS

In this prospective randomized study the stapling device significantly decreased blood loss and the transfusion requirement during radical cystectomy. These significant advantages combined with its relative safety make it an attractive surgical option and argue in favor of continued strategic attempts to decrease blood loss during radical cystectomy.

Complications of radical cystectomy for nonmuscle invasive disease: comparison with muscle invasive disease

PURPOSE

Radical cystectomy is gold standard treatment for muscle invasive bladder cancer and is an option for many patients with nonmuscle invasive disease at high risk for disease progression. We assessed the early complications of radical cystectomy among patients with nonmuscle invasive compared to those with muscle invasive disease.

MATERIALS AND METHODS

We reviewed the records of 304 consecutive patients who underwent radical cystectomy from December 1995 to July 2000. We evaluated complications that occurred within 30 days of the procedure. Cases were stratified into nonmuscle invasive (PO, Pa, P1 and PIS, N0) or muscle invasive (P2-4, N0-3) tumors based on final specimen pathology. The 2 groups were then compared with respect to age, gender, race, American Society of Anesthesiologists score, type of urinary diversion, estimated blood loss, operative time and length of stay, and major and minor complications.

RESULTS

Of the 293 available patients 105 (36.8%) had nonmuscle invasive specimen pathology. Overall major and minor complications occurred in 4.9% and 30.4% of cases, respectively. Independent t test revealed no significant difference between groups in terms of age (p = 0.85), gender (p = 0.77), race (p = 1.0), American Society of Anesthesiologists (p = 0.32), type of urinary diversion (p = 0.33), estimated blood loss (p = 0.31), operative time (p = 0.41), length of stay (p = 0.75), or presence of major (p = 0.78) or minor (p = 0.79) complications.

CONCLUSIONS

The early morbidity associated with radical cystectomy for nonmuscle invasive disease is similar to but not less than that associated with muscle invasive tumors. These acceptable risks as well as the potential benefits should be discussed with patients with nonmuscle invasive bladder cancer at high risk for disease progression.

Personalized health care and business success: can informatics bring us to the promised land?

Perrow's models of organizational technologies provide a framework for analyzing clinical work processes and identifying the management structures and informatics tools to support each model. From this perspective, health care is a mixed model in which knowledge workers require flexible management and a variety of informatics tools. A Venn diagram representing the content of clinical decisions shows that uncertainties in the components of clinical decisions largely determine which type of clinical work process is in play at a given moment. By reducing uncertainties in clinical decisions, informatics tools can support the appropriate implementation of knowledge and free clinicians to use their creativity where patients require new or unique interventions. Outside health care, information technologies have made possible breakthrough strategies for business success that would otherwise have been impossible. Can health informatics work similar magic and help health care agencies fulfill their social mission while establishing sound business practices? One way to do this would be through personalized health care. Extensive data collected from patients could be aggregated and analyzed to support better decisions for the care of individual patients as well as provide projections of the need for health services for strategic and tactical planning. By making excellent care for each patient possible, reducing the "inventory" of little-needed services, and targeting resources to population needs, informatics can offer a route to the "promised land" of adequate resources and high-quality care.

Care pathway reduces hospitalizations and cost for hemodialysis vascular access surgery

Hemodialysis vascular access-related hospitalizations account for more than 20% of United States end-stage renal disease (ESRD) hospitalizations, with an annual cost approximating $675 million. Limiting access-related costs while delivering similar degrees of quality care thus would enhance alternative utilization of ESRD funding. We implemented a vascular access care pathway emphasizing coordinated patient evaluation and outpatient surgery to determine whether such an intervention affected outcomes associated with vascular access surgery. Data examining hospitalization and vascular access surgery charges, complications, and patient satisfaction (determined by questionnaire) were analyzed, comparing patients who underwent vascular access surgery in 1994 and 1995 as inpatients (non-care pathway patients) and patients who underwent vascular access surgery via the care pathway in 1995. Inpatient days declined in 1995 (1994: 582 days; 1995: 85 days; P < 0.03) and the average charges per patient for the care pathway cohort were significantly less than charges per patient in 1994 and charges for non-care pathway patients in 1995 (1994 patients: $10,524 +/- $5,209; 1995 non-care pathway patients: $11,196 +/- $5,806; 1995 care pathway patients: $4,686 +/- $2,912/patient; P < 0.02). Incidence rates for major (life-threatening) complications were not significantly different between 1994 patients and care pathway patients in 1995. However, the 1995 non-care pathway patients had a higher incidence of major complications (15.4%). Forty-seven repeat access procedures were performed in 29 patients in 1994 versus 35 repeat access procedures in 22 care pathway patients in 1995, and 12 repeat access procedures were performed in eight non-care pathway patients in 1995. Finally, a majority of the patients entered into the care pathway who responded to a survey stated that they were satisfied with access surgery via the care pathway. These data suggest that a vascular access care pathway can reduce hospital days and costs while achieving acceptable outcomes for access surgery.

The institution of care pathways in nephrology patient care: a response to the changing health care climate

The development of managed health care in the United States has provided an impetus for new strategies that promote efficiency, streamline healthcare delivery, and maintain quality care. The increasing number of end-stage renal disease patients, their complexity of care, and a looming manpower shortage in nephrology strain the present system trying to meet these demands. One mode of healthcare delivery that may address specific needs in the nephrology population is case management. This approach to medical care uses a care pathway that serves as a multidisciplinary blueprint for patient care. Such pathways eliminate duplicated services and maximize efficiency by keeping the healthcare team focused. In response to market forces in our community, we implemented care pathways for percutaneous renal biopsy and vascular access surgery. Costs per procedure and hospital length of stay were reduced. Patient outcomes and procedure success rates were unchanged from pre-pathway years. Moreover, patients preferred the care pathway care for their problems. Case management and care pathways are tools that are effective in their scope for helping deliver better care for nephrology patients. While they should not be considered a panacea for the problems facing renal care providers, these tools should be considered as part of nephrology healthcare delivery in the future.
