The amount of cancer-related information available in the media and other sources continues to increase each year. We wondered how people make use of such content in making specific health decisions. We studied both the information they actively seek ("seeking") and that which they encounter in a less purposive way ("scanning") through a nationally(More)
PURPOSE We assessed the associations between the 21-gene recurrence score assay (RS) receipt, subsequent chemotherapy use, and medical expenditures among patients with early-stage breast cancer. PATIENTS AND METHODS Data from the Pennsylvania Cancer Registry were used to assemble a retrospective cohort of women with early-stage breast cancer from 2007 to(More)
This study explores the utility of using the Integrative Model of Behavioral Prediction as a framework for predicting cancer patients' intentions to seek information about their cancer from sources other than a physician, and to examine the relation between patients' baseline intentions to seek information and their actual seeking behavior at follow-up.(More)
This study reports an application of the integrative model to the prediction of intentions to engage in three cancer screening behaviours (mammogram, colonoscopy and PSA test) and three healthy lifestyle behaviours (exercising, eating fruits and vegetables, and controlling ones diet to lose weight). We examined the roles of attitudes, perceived behavioural(More)
Reducing cancer-related mortality rates can be achieved by increasing cancer screening rates and by increasing the number of people who engage in healthy lifestyle behaviors. This study uses the Integrative Model of Behavioral Prediction (IM; Fishbein, 2000) to examine differences between Blacks and Whites in the US in the degree to which attitudes,(More)
We present a new approach to population health, in which data-driven predictive models are learned for outcomes such as type 2 diabetes. Our approach enables risk assessment from readily available electronic claims data on large populations, without additional screening cost. Proposed model uncovers early and late-stage risk factors. Using administrative(More)
Importance Adherence to medications prescribed after acute myocardial infarction (AMI) is low. Wireless technology and behavioral economic approaches have shown promise in improving health behaviors. Objective To determine whether a system of medication reminders using financial incentives and social support delays subsequent vascular events in patients(More)
The patient-centered medical home (PCMH) is a model for restructuring primary care with a focus on improved access to care and clinical excellence. However, to date, the evidence on its effect on healthcare utilization and expenditures has been quite mixed. One possible reason for this may lie in the flexibility with which a practice can meet the thresholds(More)
281 Background: Patient experiences are an important component of quality, but information on how well oncology providers meet the specific needs of patients with cancer is limited. This study reports on the patient experiences among patients undergoing drug therapy treatment for cancer in diverse outpatient settings. METHODS We assessed patient(More)
BACKGROUND Targeted therapy for patients with lung and colon cancer based on tumor molecular profiles is an important cancer treatment strategy, but the impact of gene mutation tests on cancer treatment and outcomes in large populations is not clear. In this study, we assessed the accuracy of an algorithm to identify tumor mutation testing in administrative(More)
