Objective: Although there are several variations of laparoscopic living-donor nephrectomies, there is no consensus as to the best technique. Our objective was to describe our technique and assess the outcomes of our approach to hand-assisted laparoscopic retroperitoneal donor nephrectomies.

Methods: From July 2001 to October 2015, 507 consecutive hand-assisted laparoscopic retroperitoneal donor nephrectomies were performed.

Introduction: Patients experiencing acute myocardial infarction (AMI) are likely to visit the nearest hospital providing appropriate services since timely care is a critical determinant in the treatment and progression of AMI. We comparatively examined AMI rates in border and nonborder census tracts. The New York State (NYS) Environmental Public Health Tracking (EPHT) program, in conjunction with the Statewide Planning and Research Cooperative System, will work on developing memoranda of understanding with neighboring states to be able to more comprehensively access NYS residents' out-of-state health records.

Vascular progenitor cells show promise for the treatment of microvasculature endothelial injury. We investigated the function of renal artery progenitor cells derived from radical nephrectomy patients, in animal models of acute ischemic and hyperperfusion injuries. Present in human adventitia, CD34positive/CD105negative cells were clonal and expressed transcription factors Sox2/Oct4 as well as surface markers CXCR4 (CD184)/KDR(CD309) consistent with endothelial progenitor cells.

Reproductive effects of long-term, low-dose exposure to disinfectant by-products have not been consistently documented in large populations despite the known toxicity of high exposures and the wide-spread occurrence of low concentrations in public drinking water. We investigated the effect of low-dose exposure to total trihalomethanes (TTHM) on birth weight and gestational term in New York State. All singleton live births from 1998 through 2003 in 62 counties in New York State were linked with public water supply (PWS) system boundaries based on mother's residential address on birth certificate.

Geocoding is increasingly being used for public health surveillance and spatial epidemiology studies. Public health departments in the United States of America (USA) often use this approach to investigate disease outbreaks and clusters or assign health records to appropriate geographic units. We evaluated two commonly used geocoding software packages, ArcGIS and MapMarker, for automated geocoding of a large number of residential addresses from health administrative data in New York State, USA to better understand their features, performance and limitations.

Laboratory testing is essential for diagnosis, evaluation, and management. The objective was to describe the type of laboratory events reported in hospitals using a voluntary electronic error reporting system (e-ERS) via a cross-sectional analysis of reported laboratory events from 30 health organizations throughout the United States (January 1, 2000, to December 31, 2005). A total of 37,532 laboratory-related events were reported, accounting for 14.

As the nation witnesses the unfolding of healthcare reform, value as an expression of reduced cost and improved quality will become the watchword for the healthcare industry. New, relatively inexpensive technologies have become more widely available that can help healthcare provider organizations more easily evaluate their performance around quality and safety, thereby contributing to improved value. Senior finance leaders should play a leading role in guiding their organizations toward measuring clinical quality and monitoring performance in monetary terms, which will be increasingly important with the growing focus on value.

Success of renal transplantation, as a viable alternative to dialysis, has been tempered by long-standing racial disparities. Ethnic minorities have less access to transplantation, are less likely to be listed for transplantation, and experience a higher rate of graft failure. Reasons for the existing racial disparities at various stages of the transplantation process are complex and multi-factorial.

Healthcare providers and governmental agencies routinely collect and report data on health outcomes. In addition, governmental agencies and industry collect and report information on environmental hazards and exposures that may impact health. Use of these data for environmental public health tracking has been a challenge because these data are managed by different data stewards, may contain confidential information that must be protected, and have not been collected in a manner to facilitate linkages.

Background: Some hospitals have instituted voluntary electronic error reporting systems (e-ERSs) to gather data on medical errors, adverse events, near misses, or environmental issues in a peer review-protected environment. An e-ERS allows for real-time review, oversight, and intervention and provides insight into hospital processes in need of modification to reduce the likelihood of adverse hospital events. In a descriptive study of a standardized, Web-based reporting system, the reporting practices of physicians and nurses were compared.

Objective: To describe characteristics of inpatient medical errors involving hypoglycemic medications and their impact on patient care.

Methods: We conducted a cross-sectional analysis of medical errors and associated adverse events voluntarily reported by hospital employees and staff in 21 nonprofit, nonfederal health-care organizations in the United States that implemented a Web-based electronic error-reporting system (e-ERS) between August 1, 2000, and December 31, 2005. Persons reporting the errors determined the level of impact on patient care.

Background: Since the mid-1990s, the development of new oral antidiabetic agents (OAs) and treatment guidelines have created an opportunity to improve glycemic control in patients with type 2 diabetes.

Objectives: This study aimed to assess the prevalence of good and inadequate glycemic control across a 5-year period among patients with diabetes in the United Kingdom. It also investigated the factors associated with achieving glycemic targets.

Objective: To describe the rate and types of events reported in acute care hospitals using an electronic error reporting system (e-ERS).

Design: Descriptive study of reported events using the same e-ERS between January 1, 2001 and September 30, 2003.

Setting: Twenty-six acute care nonfederal hospitals throughout the U.

Methods And Materials: A retrospective study was conducted to (1) determine the relationship between baseline prostate-specific antigen (PSA) levels and initial treatment decisions for prostate cancer (surgery, hormone therapy, radiation, or watchful waiting) and (2) estimate the impact of PSA progression (doubling or three consecutive rises) on subsequent treatment decisions. Patient records (n=1116) from three community urology practices and a large academic health system were reviewed. Multivariate models were fitted to assess the relationship between initial treatment and baseline PSA, Gleason score, race, number of comorbid conditions and age and between PSA progression and time to subsequent therapy (adjusted for other factors).

Background: This study was designed to estimate the rates of late genitourinary (GU) and rectal toxicity after magnetic resonance image (MRI)-guided prostate brachytherapy exclusively or in conjunction with external beam radiation therapy (EBRT).

Methods: Between November 1997 and April 2002, 201 patients with category T1C prostate carcinoma (according to the 2002 American Joint Committee on Cancer staging criteria), prostate specific antigen levels < 10 ng/mL, and biopsy Gleason score 3 + 4 disease were treated with MRI-guided brachytherapy exclusively or in conjunction with EBRT. The MRI-guided technique was designed to spare the urethra based on delivery of the prescription dose to the peripheral zone exclusively.

Purpose: To identify events that precipitated a prostate-specific antigen (PSA) bounce and characterize the magnitude, duration, and time to PSA bounce after MRI-guided prostate brachytherapy.

Methods And Materials: Between 1997 and 2001, 186 patients with low-risk prostate cancer underwent MRI-guided permanent 125I source implantation, with or without external beam radiotherapy. A PSA bounce was defined as a >or=15% elevation in PSA compared with the most recent value, followed by a decline to a level at or less than the prebounce value.
