Contemporary Trends in Nephrectomy for Renal Cell Carcinoma in the United States: Results From a Population Based Cohort
ABSTRACT Despite benefits in functional renal outcome and the similar oncological efficacy of partial nephrectomy for renal cell carcinoma, previous studies show marked underuse of partial nephrectomy. We describe national trends in partial and radical nephrectomy using a contemporary, population based cohort.
Using the 2003 to 2008 Nationwide Inpatient Sample we identified 188,702 patients treated with partial or radical nephrectomy for renal cell carcinoma at a total of 1,755 hospitals. Multivariate logistic regression was used to assess the independent associations of patient and hospital characteristics with partial nephrectomy. Post-estimations from multivariate logistic regression were done to ascertain the annual predicted probability of partial nephrectomy by hospital feature.
Overall 149,636 (79.3%) and 39,066 patients (20.7%) underwent radical and partial nephrectomy for renal cell carcinoma, respectively. Partial nephrectomy use increased each year from 16.8% in 2003 to 25.1% in 2008 (p for trend <0.001). On multivariate analysis patients were more likely to undergo partial nephrectomy at teaching (OR 1.31, p <0.001) and urban (OR 1.13, p = 0.05) hospitals compared to nonteaching and rural hospitals, respectively. Each quartile of higher nephrectomy annual volume was associated with higher odds of partial nephrectomy compared to the lowest quartile (OR 1.21, p <0.001). Although annual predicted partial nephrectomy use increased across all hospitals, differences in annual partial nephrectomy use by teaching status, site (urban vs rural) and case volume persisted with time.
Although the use of partial nephrectomy for renal cell carcinoma is increasing nationally across all hospitals, academic and urban hospitals as well as those with higher nephrectomy volume continue to show higher partial nephrectomy use for renal cell carcinoma.

ABSTRACT: IntroductionThe rapid diffusion of the surgical robot has been controversial because of the technology's high costs and its disputed marginal benefit. Some, however, have suggested that adoption of the robot may have improved care for patients with renal malignancy by facilitating partial nephrectomy, an underutilized, technically challenging procedure believed to be less morbid than radical nephrectomy. We sought to determine whether institutional acquisition of the robot was associated with increased utilization of partial nephrectomy.Methods:We used all payer data from 7 states to identify 21,569 nephrectomies. These patient-level records were aggregated to the hospital-level then merged with the American Hospital Association Annual Survey and publicly available data on timing of robot acquisition. We used a multivariable difference-in-difference model to assess at the hospital-level whether robot acquisition was associated with an increase in the proportion of partial nephrectomy, adjusting for hospital nephrectomy volume, year of surgery, and several additional hospital-level factors.Results:In the multivariable-adjusted differences-in-differences model, hospitals acquiring a robot between 2001 and 2004 performed a greater proportion of partial nephrectomy in both 2005 (29.9% increase) and 2008 (34.9% increase). Hospitals acquiring a robot between 2005 and 2008 also demonstrated a greater proportion of partial nephrectomy in 2008 (15.5% increase). In addition, hospital nephrectomy volume and urban location were also significantly associated with increased proportion of partial nephrectomy.Conclusions:Hospital acquisition of the surgical robot is associated with greater proportion of partial nephrectomy, an underutilized, guideline-encouraged procedure. This is one of the few studies to suggest robot acquisition is associated with improvement in quality of patient care.The 35th Annual Meeting of the Society for Medical Decision Making; 10/2013

ABSTRACT: There is a growing body of experience and research suggesting that telemedicine (video conferencing, smart phones and online patient portals) could be the solution to addressing gaps in the provision of specialised healthcare in rural areas. The proposed role of telemedicine in providing needed services in hard to reach areas is not new. The United States Telecommunication Act of 1996 provided the initial traction for telemedicine by removing important economic and legal obstacles regarding the use of technology in healthcare delivery. This initial ruling has been supplemented by the availability of federal funding to support efforts aimed at developing telemedicine in underserved areas. In this paper, we explore one aspect of disease disparity pertinent to rural Illinois (kidney cancer incidence and mortality) and describe how we are planning to use an existing telemedicine program at Southern Illinois University School of Medicine (SIUSOM) to improve kidney cancer (Kca) care in rural Illinois. This represents an example of the possible role of telemedicine in addressing healthcare disparities in rural areas/communities and provides a description of general challenges and barriers to the implementation and maintenance of such systems.European Journal of Cancer Care 11/2014; 23(6).
