Impact of malpractice caps on use and outcomes of radical cystectomy for bladder cancer: data from the surveillance, epidemiology, and end results program

PURPOSE: The impact of malpractice awards on insurance premiums and health care delivery generates much concern. To our knowledge no data exist regarding the impact of caps, or upper limits, on awards for noneconomic damages (also termed pain and suffering) on health care delivery patterns or outcomes. We investigated the effect of caps on the use of and outcomes following aggressive surgical treatment (radical cystectomy) in patients with bladder cancer. MATERIALS AND METHODS: We performed a retrospective cohort study of patients with bladder cancer who underwent radical cystectomy, identified from the Surveillance, Epidemiology, and End Results (SEER) Program database. Cystectomy rates and post-cystectomy disease specific survival were compared between SEER regions with and without a cap, while controlling for other variables. RESULTS: A significantly greater proportion of patients with stages III and IV bladder cancer underwent cystectomy in SEER regions with a cap. Cap status was a significant predictor of survival from bladder cancer. CONCLUSIONS: Radical cystectomy for bladder cancer is performed more often even for advanced bladder cancer in geographic regions with a cap with a positive impact on survival. The institution of caps may have beneficial effects on patterns of health care beyond that of merely decreasing insurance premium costs.     

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.     

Comparison of clinical productivity of senior dental students in a dental school teaching clinic versus community externship rotations

The aim of this study was to report on the clinical and monetary productivity of fourth-year dental students at community-based clinical sites and school-based clinics at the Harvard School of Dental Medicine (HSDM). This study included forty-seven students from the graduating classes of 2006, 2007, and 2008. These fourth-year students were required to spend twelve weeks at one of several participating community health centers throughout Massachusetts and New Hampshire. Students also treated their patient pool in the teaching practice at HSDM in the fourth year. The most common sixty American Dental Association procedure codes were compared, and variables were created by grouping them by specialty or type of service. HSDM dental students completed 8,365 procedures at an externship site during their community experience. An average of 178 procedures was completed per student, and mean revenue of $17,486 was produced. In comparison, the same students completed 3,640 procedures during an equal amount of time spent (normalized for this study) at the school teaching practice clinic, where each student completed an average of seventy-seven procedures and generated $16,802 in revenue. The results of this study show that fourth-year dental students at the community health centers, working under the supervision of adjunct faculty, completed more than double the number of procedures they did in the HSDM teaching practice clinic. However, the revenue generated was very similar at the two sites. In addition, the types of procedures performed by students at externship sites were simpler than the complex and specialized procedures performed at the HSDM clinic, which include fixed and removable prosthetics, periodontal surgery, and implantology.     

Influence of post-cystectomy complications on cost and subsequent outcome

PURPOSE: Of commonly performed urological cancer procedures radical cystectomy is associated with the highest morbidity and mortality. The impact of each individual type of complication or a combination of them on various outcome measures, such as mortality, charges and length of stay, is unclear. We quantified the impact of specific post-cystectomy complications and combinations thereof in terms of mortality, charges and length of stay. MATERIALS AND METHODS: All 6,577 patients undergoing radical cystectomy for bladder cancer were identified from the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project (1998 to 2002). The prevalence of different International Classification of Diseases, 9th Revision, Clinical Modification coded complications following cystectomy were determined. Outcome variables of interest were in-hospital mortality, total charges and length of stay. The association between types of complications and measured outcomes were examined using univariate and multivariate regression models. The cumulative impact of multiple complications and various combinations of complications on outcomes was also examined. RESULTS: The overall complication rate was 28.4% in 1,869 cases and the mortality rate was 2.6%. Median total charges was 41,905 dollars and median length of stay was 9 days. Overall 20.7% of patients had 1, 6.1% had 2, 1.2% had 3 and 0.42% had greater than 3 complications. At least 1 complication almost doubled the odds of mortality and increased median total charges and length of stay by 15,000 dollars and 4 days, respectively. We defined expected levels of increase in the various outcome measures with increasing numbers of complications. The combination of postoperative infection and respiratory complication had the greatest impact on mortality, while the combination of wound and urinary tract infection had the greatest impact on length of stay and total charges. CONCLUSIONS: Although most patients undergoing cystectomy are older and have multiple comorbidities, the postoperative complications with the most significant impact were those directly related to surgery (primary complications). Secondary complications (cardiac, respiratory, vascular, etc) appear to have less of an impact on most common outcome measures. Hence, the greatest gains can be achieved by limiting primary complications. These data could be used to develop benchmarks of expected levels of primary and secondary complications after cystectomy.     

Analysis of complications following partial and total nephrectomy for renal cancer in a population based sample

PURPOSE: We determined the frequency and predictors of complications of partial and total nephrectomy in a population based sample. MATERIALS AND METHODS: There were 3,019 partial and 18,575 total nephrectomies identified from the Nationwide Inpatient Sample data set of the Healthcare Cost and Utilization Project (2000 to 2003). The prevalence of International Classification of Diseases, 9th Revision coded complications following nephrectomy was determined. Hospital and patient related factors associated with the occurrence of a complication were determined by logistic regression analysis. We evaluated the impact of complications on in-hospital mortality, length of stay and hospital charges. RESULTS: Respiratory, digestive and bleeding complications were the most common, with similar patterns for partial nephrectomy and total nephrectomy. Significant predictors of complications after total nephrectomy included age, male sex, comorbidity severity index and hospital location (rural vs urban), while comorbidity was the only significant predictor for partial nephrectomy complications. Any complication had a significant impact on in-hospital mortality, total charges and length of stay. Digestive and urinary complications, hemorrhage, and postoperative infections had a significant impact on in-hospital mortality after partial nephrectomy, while these same complications, in addition to respiratory and cardiac complications, had a significant impact on total charges and length of stay. All except digestive complications had a significant impact on mortality, hospital charges and length of stay for patients undergoing total nephrectomy. CONCLUSIONS: In a population based cohort partial nephrectomy and total nephrectomy are associated with low morbidity and mortality profiles, and all complications affect mortality, length of hospital stay and charges.     

Factors affecting outcomes after radical cystectomy in African Americans

BACKGROUND: Previous studies indicate that African Americans with bladder cancer have a worse outcome than Caucasians. Delay in seeking care and higher stage at presentation have been cited as possible reasons for the observed differences. The authors hypothesized that differences in hospital volume where patients undergo radical cystectomy may be responsible for race-based differences in outcomes after the procedure. METHODS: The authors analyzed data from the Health Care Cost and Utilization Project and identified 4862 patients who had undergone radical cystectomy between 1998 and 2002. In-hospital mortality, complications, and length of stay (LOS) in hospital were compared between patients grouped by race. Hospitals were categorized into tertiles by the average number of radical cystectomies performed per year (1-4 radical cystectomies, 5-10 radical cystectomies, and >10 radical cystectomies). Univariate and multivariate analyses were performed to determine predictors of mortality, complications, LOS, and the likelihood that patients would undergo cystectomy at a high/medium-volume hospital. RESULTS: African Americans had the highest in-patient mortality, complications, and LOS after radical cystectomy. They also were the least likely to undergo radical cystectomy at a high/medium-volume hospital. When the analyses were controlled for potential confounding factors, there was no difference in in-hospital mortality by race, but differences persisted in the other 3 outcome variables. African Americans had higher odds of complications (odds ratio [OR], 1.57; P = .001), longer LOS (25%; P = .001), and lower odds of undergoing cystectomy at a high/medium-volume hospital (OR, 0.74; P = .03) compared with Caucasians. CONCLUSIONS: Race was an important factor in determining outcomes after radical cystectomy for bladder cancer. African Americans were less likely to undergo cystectomy at a high-volume hospital, thereby placing them at a higher risk of postoperative complications which ultimately may affect their survival.
