BACKGROUND The number of total shoulder arthroplasties performed in the United States increased slightly between 1990 and 2000. However, the incidence of shoulder arthroplasty in recent years has not been well described. The purpose of the present study was to examine recent trends in shoulder hemiarthroplasty and total shoulder arthroplasty along with the(More)
BACKGROUND This study was proposed to investigate the changes in the utilization of knee arthroscopy in an ambulatory setting over the past decade in the United States as well as its implications. METHODS The National Survey of Ambulatory Surgery, last carried out in 1996, was conducted again in 2006 by the Centers for Disease Control and Prevention. We(More)
BACKGROUND It is unclear whether simultaneous-bilateral total knee arthroplasty is as safe as staged-bilateral arthroplasty is. We are aware of no randomized trials comparing the safety of these surgical strategies. The purpose of this study was to retrospectively compare these two strategies, with use of an intention-to-treat approach for the(More)
OBJECTIVE A major component of the economic burden associated with the treatment of arthritis relates to surgical joint replacements of the hips/knees.

BACKGROUND Patient-reported measures can be used to examine whether drug differences other than clinical efficacy have an impact on outcomes that may be important to patients. Although exenatide and insulin glargine appear to have similar efficacy for treatment of type 2 diabetes, there are several differences between the two treatments that could influence(More)
In 2000, a representative sample of the elderly population (60 years or older) was selected from seven urban cities in Latin America and the Caribbean: Buenos Aires (Argentina), Mexico City (Mexico), Santiago (Chile), Havana (Cuba), Montevideo (Uruguay), Bridgetown (Barbados), and Sao Paulo (Brazil). A face-to-face interview was uniformly administered in(More)
BACKGROUND This study characterized human immunodeficiency virus (HIV) testing and high-risk behavior among 18 to 22 year-old college students and nonstudents. METHODS Data from 18 to 22 year-olds (n = 2007) in Cycle 6 of the National Survey of Family Growth, a nationally representative survey conducted between March 2002 and February 2003, were analyzed(More)
This study describes the burden of potentially preventable hospitalizations primarily due to uncontrolled diabetes. Uncontrolled diabetes, if not managed properly, often leads to biochemical imbalances that can cause acute life-threatening events and hospitalizations. Since diabetes management relies heavily on ambulatory care, hospitalizations with(More)
Two objectives of this study were (i) to estimate the number of primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) performed on morbidly obese people in the United States, and (ii) to estimate the economic impact of morbid obesity on hospital resource use. In 2006, approximately 2.9% (6713 cases) of primary THA and 4.2% (20,964 cases) of(More)
