The relationship between provider volume and complication and transfusion rates in patients undergoing minimally invasive prostatectomy (MIRP) for prostate cancer has not been assessed. Temporal trends in MIRP annual surgical caseload (AC), impact of MIRP surgical experience (SE), and in-hospital complication and transfusion rates were evaluated. Between 2002 and 2008, 2,666 patients in Florida underwent MIRP. Surgical experience was defined as the number of procedures performed from the beginning of the study until each individual MIRP. Multivariable logistic regression models using generalized estimating equations assessed the relationship between SE and in-hospital complication and transfusion rates. Overall AC and SE ranged from 1-171 and 1-500, respectively. Between 2002 and 2005, 94-100% of surgeons were considered as low AC tertile (a parts per thousand currency sign15 MIRP) vs. 76-82% between 2006 and 2008. For the same time periods, low AC tertile surgeons performed 46-100 and 27-32% of all MIRPs respectively. Multivariable logistic regression models revealed 51 and 68% lower complication rates in patients operated on by surgeons of intermediate (17-76 MIRPs) and high SE (a parts per thousand yen77 MIRPs) relative to surgeons of low SE (a parts per thousand currency sign16 MIRPs). Similarly, transfusion rates were 80 and 83% lower for the same groups. Our study is the first to indicate that high SE reduces MIRP complication and transfusion rates. Despite this observation, even in the most contemporary study year, most MIRP surgeons (82%) were in the low AC tertile and contributed to as many as 32% of all MIRPs. These findings should be considered at informed consent.

The adherence rate to National Cancer Institute (NCI) recommendations regarding inguinal lymph nodes dissection (ILND) in high grade T1 (G3T1) and T2-4 squamous cell carcinoma of the penis (SCCP) is not known. We assessed ILND rates in a North American cohort. The 17 registries of the Surveillance, Epidemiology, and End Results (SEER) database included 868 patients with SCCP, diagnosed between 1988 and 2006. Analyses consisted of univariable and multivariable logistic regression models. Overall, 27.6% of patients underwent an ILND. ILND rates were directly proportional with T stage: 19.0%, 30.5%, 30.6%, and 32.6% for, respectively, G3T1, T2, T3, and T4 SCCP (chi-square trend, P = 0.01). ILND rates also increased over time and were 19.3, 27.3, 30.7, and 30.8% for respectively, 1988–1995, 1996–2000, 2001–2003, and 2004–2006 periods (chi-square trend, P = 0.03). Finally, ILND rates decreased with patient age and were 42.6, 33.2, 24.7, and 7.3% for, respectively, patients aged ≤57, 58–68, 69–78 and ≥79 years of age (chi-square trend, P

Purpose: We tested the relationship between caseload and total hospital charges after stratifying by minimally invasive and open radical prostatectomy. Materials and Methods: We evaluated 1,188 vs 3,354 men treated with minimally invasive vs open radical prostatectomy in the Florida Hospital Inpatients data file in 2008. Caseload was defined as the count of procedures performed by each surgeon between the study start on January 1, 2008 and the date of each procedure. Patients were divided into tertiles based on their procedure specific caseload. Univariate and multivariate analysis was done to address the relation between caseload and total hospital charges for the minimally invasive and open procedures. Covariates were patient age, race, comorbidity, and length of stay. Results: Median total hospital charges for minimally invasive and open radical prostatectomy were $33,234 and $33,674, respectively (p = 0.03). Median total hospital charges in the low, intermediate and high minimally invasive vs open procedure caseload tertiles were $41,765, $34,799 and $28,780 vs $35,642, $34,726 and $32,726, respectively. On multivariate analysis with the high minimally invasive caseload tertile as the reference category the increments of the probability of charges in excess of the 2008 median of $33,588 were 3.9 and 8.1-fold for the intermediate and low caseload minimally invasive procedures, and 2.5, 3.6 and 2.8-fold for the high, intermediate and low caseload open procedures, respectively (each p < 0.001). Conclusions: Overall median total hospital charges are virtually the same for minimally invasive and open radical prostatectomy. However, total hospital charges for the minimally invasive procedure have a more sensitive caseload effect, as evidenced by the wider distribution of the median of minimally invasive caseload specific total hospital charges vs that of open radical prostatectomy. The high caseload minimally invasive procedure resulted in the lowest total hospital charges relative to all other minimally invasive and open radical prostatectomy categories.

OBJECTIVE To evaluate the relationship between surgical volume (SV) and total hospital charges in patients undergoing minimally invasive radical prostatectomy (MIRP) for treatment of localized prostate cancer. PATIENTS AND METHODS Within the Florida Hospital Inpatient Datafile, 2666 men who were treated with MIRP for prostate cancer between 20022008 were identified. The SV was defined in two ways: annual caseload (AC) and each surgeons experience (SE) defined as the total number of procedures performed since entering the study until the time of each MIRP. RESULTS The mean and median charges were respectively 38 852 and 31 511 US Dollars. AC ranged from 1-171 and SE varied from 1-500. Overall, 75.7 to 94% of surgeons were in the lowest AC tertile and 27 to 66% of patients were operated by low AC tertile surgeons. After stratification according to AC tertiles, median charges were 41 564; 33 395 and 26 608 US Dollar for respectively low intermediate and high AC tertile categories. Multivariable logistic regression models with generalized estimating equations revealed that the probability of charges above the median was reduced by respectively 38 and 68% in patients operated by intermediate SE (17-76 MIRPs) or high SE tertile (>= 77 MIRPs) surgeons vs. low SE tertile (

Background On average, patients remain hospitalized no more than 2 days after MIRP. The aim of our study was to examine the temporal trends in length of stay ≥3 days and to test the relationship between annual surgical volume (ASV) and annual hospital volume (AHV) and length of stay ≥3 days in patients undergoing MIRP. Material and methods Within the Florida Hospital Inpatient Datafile, 2439 men who were treated with MIRP for prostate cancer between 2005 and 2008 were identified. Temporal trends were assessed and uni and multi-variable logistic regression models tested the relationship between ASV, AHV and length of stay ≥3 days. Results The average length of stay decreased from 2.4 in 2005 to 1.7 days in 2008. Length of stay ≥3 days was recorded in 13.6% of patients and the proportion of patients staying more than ≥3 days decreased over time (25.5–12.2%; Chi Square trend p

Purpose: Radical prostatectomy is the standard of care for localized prostate cancer. Numerous previous reports show the relationship between surgical experience and various outcomes. We examined the effect of surgical experience on complications and transfusion rates, and determined individual surgeon annual caseload trends in a contemporary radical prostatectomy cohort. Materials and Methods: We analyzed annual caseload temporal trends in 34,803 patients who underwent surgery between 1999 and 2008 in Florida. Logistic regression models controlled for clustering among surgeons addressed the relationship of surgical experience, defined as the number of radical prostatectomies done since January 1, 1999 until each radical prostatectomy, with complications and transfusions. Results: During the study period the proportion of surgeons in the high annual caseload tertile (24 radical prostatectomies or greater yearly) and the proportion of patients treated by those surgeons increased from 5% to 10% and from 20% to 55%, respectively. Conversely complication and transfusion rates decreased from 14.3% to 9.2% and 12.6% to 6.9%, respectively. Radical prostatectomies done by surgeons in the high surgical experience tertile (86 or greater radical prostatectomies) decreased the risk of any complication by 33% and of any transfusion by 30% vs those in patients operated on by surgeons in the low surgical experience tertile (27 or fewer radical prostatectomies). Conclusions: The proportion of surgeons in the high annual caseload tertile and the proportion of patients treated by these surgeons steadily increased during the last decade. Complication and transfusion rates decreased with time. The implications of these encouraging findings may result in improved outcomes in patients with surgically managed prostate cancer.
