CONTEXT Common bile duct (CBD) injury during cholecystectomy is a significant source of patient morbidity, but its impact on survival is unclear. OBJECTIVE To demonstrate the relation between CBD injury and survival and to identify the factors associated with improved survival among Medicare beneficiaries. DESIGN, SETTING, AND PATIENTS Retrospective(More)
The aim of this review paper is to summarize recent developments in the field of wearable sensors and systems that are relevant to the field of rehabilitation. The growing body of work focused on the application of wearable technology to monitor older adults and subjects with chronic conditions in the home and community settings justifies the emphasis of(More)
The general objective of the Rehabilitation Medicine Summit: Building Research Capacity was to advance and promote research in medical rehabilitation by making recommendations to expand research capacity. The 5 elements of research capacity that guided the discussions were: (1) researchers, (2) research environment, infrastructure, and culture, (3) funding,(More)
CONTEXT Patients in rural areas may use less medical care than those living in urban areas. This could be due to differences in travel distance and time and a utilization of a different mix of generalists and specialists for their care. PURPOSE To compare the travel times, distances, and physician specialty mix of all Medicare patients living in Alaska,(More)
The purpose of this study was to examine the feasibility of an intervention that included heart rate variability (HRV) biofeedback and walking with pulse oximetry feedback to improve functioning and quality of life for patients with chronic obstructive pulmonary disease (COPD). Twenty patients with COPD participated in 5 weekly sessions of HRV biofeedback(More)
Respiratory sinus arrhythmia (RSA) may be associated with improved efficiency of pulmonary gas exchange by matching ventilation to perfusion within each respiratory cycle. Respiration rate, tidal volume, minute ventilation (.VE), exhaled carbon dioxide (.VCO(2)), oxygen consumption (.VO(2)), and heart rate were measured in 10 healthy human volunteers during(More)
Loss of physical mobility makes maximal participation in desired activities more difficult and in the worst case fully prevents participation. This paper surveys recent work in assistive technology to improve mobility for persons with a disability, drawing on examples observed during a tour of academic and industrial research sites in Europe. The underlying(More)
BACKGROUND A previous randomised controlled trial reported greater efficacy of surgery than of splinting for patients with carpal tunnel syndrome. Our aim was to compare surgical versus multi-modality, non-surgical treatment for patients with carpal tunnel syndrome without denervation. We hypothesised that surgery would result in improved functional and(More)
Mobility technologies, including wheelchairs, prostheses, joint replacements, assistive devices, and therapeutic exercise equipment help millions of people participate in desired life activities. Yet, these technologies are not yet fully transformative because many desired activities cannot be pursued or are difficult to pursue for the millions of(More)
CONTEXT Medicare's Incentive Payment (MIP) program provides a 10% bonus payment to providers who treat Medicare patients in rural and urban areas where there is a shortage of generalist physicians. PURPOSE To examine the experience of Alaska, Idaho, North Carolina, South Carolina, and Washington with the MIP program. We determined the program's(More)
