BACKGROUND The relationship between change in cognitive and physical performance has yet to be fully understood. Because aging decreases the ability to learn new information while preserving more established knowledge, this article examines whether the association between change in cognitive and physical performance depends on the nature of the physical(More)
BACKGROUND Genetic testing has the potential to identify persons at high risk for disease. Given the history of racial disparities in screening, early detection and accessing treatment, understanding racial differences in beliefs about genetics is essential to preventing disparities in some conditions. METHODS In 2004, a sample of older adult patients(More)
BACKGROUND The US experienced a shortage of varicella vaccine in 2002, leading to the concerns about its impact. METHODS 204 Minnesota and Pennsylvania physicians, most (164) of whom were interviewed in 1999 on the topic of varicella vaccine, responded to a 2003 survey. RESULTS Although 67% were aware of the 2002 varicella vaccine shortage, 24%(More)
BACKGROUND Pneumococcal polysaccharide vaccination rates among adults 65 years and older or less than 65 years with high risk medical conditions are still below Healthy People 2010 recommended levels of 90%. This study was designed to: 1) assess self-reported pneumococcal vaccination rates following health center level interventions to increase adult(More)
Although colorectal cancer (CRC) is the second leading cause of cancer death in the U.S., screening rates are low. Understanding the predictors of CRC screening is needed. In 2003, a random sample of patients aged 50 and over from three inner-city health centers was surveyed by computer-assisted telephone interview concerning CRC screening. The(More)
OBJECTIVES We designed and evaluated interventions to increase adult immunizations within inner-city health centers. METHODS Interventions included reminders, standing orders, and walk-in "flu shot clinics." Patients were surveyed and records evaluated. RESULTS Records from 1 center showed that immunization rates increased from 24% to 30% (P <.001) for(More)
This pilot study examined the covariation of patients' self-reports of instrumental and affective aspects of communication during physician-patient visits with 2 other sources of data: medical chart records and audio/videotapes. Participants were 17 community-based (nonuniversity) primary-care physicians and 77 of their patients, ages 50 to 80. Patients(More)
We determined the barriers to and facilitators of colorectal cancer (CRC) screening among two faith-based, inner city neighborhood health centers in Southwestern Pennsylvania. Data from a random sample of patients 50 years and older (n = 375) were used to estimate logistic regression equations to compare and contrast the predictors of four different CRC(More)
BACKGROUND Despite the availability of pneumococcal polysaccharide vaccine (PPV), vaccination rates are modest, and racial disparity in these rates is known to occur. OBJECTIVE The purpose of this study was to identify determinants of patient-reported receipt of PPV among patients from 3 inner-city health centers that serve large numbers of minority and(More)
PURPOSE Vaccination rates for pneumococcal polysaccharide vaccine (PPV) and influenza vaccine are relatively low in disadvantaged urban populations. This study was designed to assess which physician and practice characteristics might explain differences in rates across physicians. METHODS PPV and influenza vaccination rates were determined for 2,021(More)
