Veterans walk to beat back pain: study rationale, design and protocol of a randomized trial of a pedometer-based Internet mediated intervention for patients with chronic low back pain

<p>Abstract</p> <p>Background</p> <p>Chronic back pain is a significant problem worldwide and may be especially prevalent among patients receiving care in the U.S. Department of Veterans Affairs healthcare system. Back pain affects adults at all ages and is associated with disability, lost workplace productivity, functional limitations and social isolation. Exercise is one of the most effective strategies for managing chronic back pain. Yet, there are few clinical programs that use low cost approaches to help patients with chronic back pain initiate and maintain an exercise program.</p> <p>Methods/Design</p> <p>We describe the design and rationale of a randomized controlled trial to assess the efficacy of a pedometer-based Internet mediated intervention for patients with chronic back pain. The intervention uses an enhanced pedometer, website and e-community to assist these patients with initiating and maintaining a regular walking program with the primary aim of reducing pain-related disability and functional interference. The study specific aims are: 1) To determine whether a pedometer-based Internet-mediated intervention reduces pain-related functional interference among patients with chronic back pain in the short term and over a 12-month timeframe. 2) To assess the effect of the intervention on walking (measured by step counts), quality of life, pain intensity, pain related fear and self-efficacy for exercise. 3) To identify factors associated with a sustained increase in walking over a 12-month timeframe among patients randomized to the intervention.</p> <p>Discussion</p> <p>Exercise is an integral part of managing chronic back pain but to be effective requires that patients actively participate in the management process. This intervention is designed to increase activity levels, improve functional status and make exercise programs more accessible for a broad range of patients with chronic back pain.</p> <p>Trial Registration Number</p> <p>NCT00694018</p

Health Care Resource Utilization Associated with a Diabetes Center and a General Medicine Clinic

OBJECTIVE: Studies have proposed that the features of diabetes clinics may decrease hospital utilization and costs by reducing complications and providing more efficient outpatient care. We compared the health care utilization associated with a diabetes center (DC) and a general medicine clinic (GMC). DESIGN: Retrospective cohort study. SETTING: An urban academic medical center. PATIENTS/PARTICIPANTS: Type 2 diabetes patients (N = 601) under care in a DC and GMC before March 1996. MEASUREMENTS AND MAIN RESULTS: We compared baseline patient characteristics and outpatient care for the period of March 1996 to August 1997. Using administrative data from March 1996 to October 2000, we compared the probability of a hospitalization, length of stay, costs of hospitalizations, the probability of an emergency room visit, and costs of emergency room visits. Diabetes center patients had a longer mean duration of diabetes (12 years vs 6 years, P < .01), more baseline microvascular disease (65% vs 44%, P < .01), and higher baseline glucose levels (hemoglobin A(1c) 8.6% vs 7.9%, P < .01) than GMC patients. Diabetes center patients received more intensive outpatient care directed toward glucose monitoring and control. In all crude and adjusted analyses of hospitalizations and emergency room visits, we found no statistically significant differences for inpatient utilization or cost outcomes comparing clinic populations. CONCLUSIONS: Diabetes center attendance did not have a definitive positive or negative impact on inpatient resource utilization over a 4-year period. However, DC patients had more severe diabetes but no greater hospital utilization compared with GMC patients. Clear demonstration of the clinical and financial benefits of features of diabetes centers will require long-term controlled trials of interventions that promote comprehensive diabetes care, including cardiovascular prevention
