OBJECTIVE Critically ill patients require high-intensity care and may be at especially high risk of iatrogenic injury because they are severely ill. We sought to study the incidence and nature of adverse events and serious errors in the critical care setting. DESIGN We conducted a prospective 1-year observational study. Incidents were collected with use(More)
BACKGROUND Although sleep deprivation has been shown to impair neurobehavioral performance, few studies have measured its effects on medical errors. METHODS We conducted a prospective, randomized study comparing the rates of serious medical errors made by interns while they were working according to a traditional schedule with extended (24 hours or more)(More)
PURPOSE We evaluated a patient cohort with renal tumors 4 cm. or less treated with partial or radical nephrectomy. We compared patient and tumor characteristics, and survival in these 2 groups. MATERIALS AND METHODS We retrospectively analyzed the records of 670 patients with a median age of 63 years treated surgically for renal cell carcinoma between(More)
PURPOSE Few published studies have combined prognostic factors to predict the likelihood of recurrence after surgery for renal cell carcinoma. We developed a nomogram for this purpose. MATERIALS AND METHODS With Cox proportional hazards regression analysis, we modeled pathological data and disease followup for 601 patients with renal cell carcinoma who(More)
BACKGROUND Knowledge of the physiological effects of extended (24 hours or more) work shifts in postgraduate medical training is limited. We aimed to quantify work hours, sleep, and attentional failures among first-year residents (postgraduate year 1) during a traditional rotation schedule that included extended work shifts and during an intervention(More)
This study was conducted to determine whether Pneumocystis carinii dyhydropteroate synthase (DHPS) gene mutations in AIDS patients with P. carinii pneumonia (PCP) are affected by duration of sulfa or sulfone prophylaxis and influence response to sulfa or sulfone therapy. The P. carinii DHPS genes from 97 AIDS patients with PCP between 1991 and 1999 from 4(More)
BACKGROUND Despite the importance of early detection in preventing mortality from melanoma, little is known regarding how patients with the disease come to diagnosis. METHODS The authors prospectively evaluated 471 newly diagnosed melanoma patients between 1995 and 1998. Patients completed a questionnaire that included 1) identification of the person who(More)
To characterize the clinical features of human immunodeficiency virus (HIV)-associated fever of unknown origin (FUO) in the United States, we performed a retrospective analysis of cases that fulfilled specific criteria (published by Durack and Street in 1991) at two medical centers in the United States between 1992 and 1997. Seventy cases met criteria for(More)
OBJECTIVES This study was performed to determine which histologic types of renal cell carcinoma have an association with a second primary malignancy. METHODS Seven hundred sixty-three patients underwent an operation for renal cell carcinoma between July 1989 and January 1999. The incidence of antecedent, synchronous, or subsequent second malignancies was(More)
Health disparities are increasingly common and many U.S. practitioners have informal experience working in resource-poor settings. There are, however, few graduate medical education programs that focus on health equity. A graduate medical education program in health equity was developed at Brigham and Women's Hospital based on a review of existing(More)
