Controversy continues as to whether traumatic brain injury is a risk factor for Alzheimer's disease. The authors examined a related hypothesis that among persons with traumatic brain injury who develop Alzheimer's disease, time to onset of the disease is reduced. They used data on all documented episodes of traumatic brain injury that occurred from 1935 to(More)
BACKGROUND Population growth, an aging population and the increasing prevalence of chronic disease are projected to increase demand for primary care services in the United States. OBJECTIVE Using systems engineering methods, to re-design physician patient panels targeting optimal access and continuity of care. DESIGN We use computer simulation methods(More)
BACKGROUND Older adults with multiple chronic illnesses are at risk for worsening functional and medical status and hospitalization. Home telemonitoring may help slow this decline. This protocol of a randomized controlled trial was designed to help determine the impact of home telemonitoring on hospitalization. The specific aim of the study reads as(More)
Patient-reported outcomes (PROs) capture how patients perceive their health and their health care; their use in clinical research is longstanding. Today, however, PROs increasingly are being used to inform the care of individual patients, and document the performance of health care entities. We recently wrote and internally distributed an institutional(More)
PURPOSE Patients leaving the hospital are at increased risk of functional decline and hospital readmission. The Employee and Community Health service at Mayo Clinic in Rochester developed a care transition program (CTP) to provide home-based care services for medically complex patients. The study objective was to determine the relationship between CTP use,(More)
BACKGROUND Using telemedicine for older adults with multiple comorbid conditions is a potential area for growth in health care. Given this older, ailing population, providers should discuss end-of-life care with patients. OBJECTIVE To determine the relationship between telemonitoring and hospice enrollment compared to usual care among older adults with(More)
A wealth of research using the Health Belief Model provides empirical evidence of the model's utility in predicting health, illness, and sick role behaviors. Until recently, however, little attention has been paid to the important issues of the validity and reliability of measures used to assess various health belief dimensions. Using factor analysis, our(More)
A matched case-control design is a common approach used to assess disease-exposure relationships, and is often a more efficient method than an unmatched design. However, for the valid analysis of such an approach, a modeling technique that incorporates the matched nature of the data is needed. This prohibits the use of a standard unconditional logistic(More)
