Asthma and mental disorders in primary care.

This study examines relationships between asthma and likelihood of current mental disorders and suicidal ideation in an urban primary care population. A systematic waiting room sample of 998 adult patients was screened for mental disorders using the PRIME-MD PHQ. Asthma diagnoses were provided by primary care physicians. Multivariate logistic regression analyses were used to determine the odds of current major depression, panic attacks, generalized anxiety disorder, alcohol and drug use disorder, and suicidal ideation among patients with a diagnosis of asthma, as compared to those without asthma. After controlling for differences in sociodemographic characteristics and comorbid mental disorders, asthma was associated with increased likelihood of panic attack (OR=1.7 (1.1, 2.6)) and suicidal ideation (OR=1.9 (1.03, 3.4)). There was no statistically significant association between asthma and major depression, generalized anxiety disorder, alcohol, or drug use disorders after adjustment. Results suggest that physician-diagnosed asthma is associated with self-reported panic attacks and suicidal ideation in a systematic sample of primary care patients. Physicians who treat patients with asthma should remain vigilant for the presence of comorbid psychiatric problems and carefully evaluate whether there is a clinical need to treat each condition.

Usability in the real world: assessing medical information technologies in patients' homes.

OBJECTIVE: This paper presents an approach to usability evaluation of computer-based health care systems designed for patient use in their homes. Although such devices are becoming more prevalent, there is very little known about their usability. DESIGN: The theoretical foundations for the methods are discussed. The approach incorporates a cognitive walkthrough usability evaluation and new methods for usability testing that can be conducted in patient's homes. The method was applied to the IDEATel intervention, a multi-institution randomized controlled trial of the feasibility, acceptability, and clinical utility of a home-based telemedicine system for diabetic Medicare population. The usability study was designed to assess barriers to optimal use of the system. The focus was both on dimensions of the interface and on dimensions of patient skills and competency. The usability field research involved testing 25 patients in their homes using the system. The analysis included a range of video-analytic methods of varying levels of granularity. RESULTS: The usability evaluation revealed aspects of the interface that were sub-optimal and impeded the performance of certain tasks. It also found a range of patient-related factors such as numeracy and psychomotor skills that constituted barriers to productive use. CONCLUSIONS: A multifaceted usability approach provided important insight regarding use of technology by an elderly chronic-care patient population and more generally, for understanding how home health initiatives can more effectively use such technology.

The role of nurses in installing telehealth technology in the home.

Home telehealth involves the use of video conferencing or remote monitoring equipment in patients' homes. The installation of hardware and training of patients has historically been performed by nurses, typically RNs. This article examines the experience of RNs as telehealth installers in the Informatics for Diabetes Education and Telemedicine (IDEATel) project, where RNs were responsible for the installation of the Home Telemedicine Units (HTUs) and for training patients in the use of the HTUs, blood pressure cuffs, and fingerstick glucose meters. Average installation and training time was 166 minutes (SD 51 min). Structured interviews with RN installers revealed that patient education and training accounted for roughly two thirds of the in-home time. Technology-related problems, especially those related to telecommunications, were the primary cause of installation difficulties. Thematic analysis of installer interviews identified eight major themes and confirmed the importance of both clinical and technical knowledge during the telehealth installation process.

Columbia University's Informatics for Diabetes Education and Telemedicine (IDEATel) project: technical implementation.

The Columbia University Informatics for Diabetes Education and Telemedicine IDEATel) project is a four-year demonstration project funded by the Centers for Medicare and Medicaid Services with the overall goal of evaluating the feasibility, acceptability, effectiveness, and cost-effectiveness of telemedicine. The focal point of the intervention is the home telemedicine unit (HTU), which provides four functions: synchronous videoconferencing over standard telephone lines, electronic transmission for fingerstick glucose and blood pressure readings, secure Web-based messaging and clinical data review, and access to Web-based educational materials. The HTU must be usable by elderly patients with no prior computer experience. Providing these functions through the HTU requires tight integration of six components: the HTU itself, case management software, a clinical information system, Web-based educational material, data security, and networking and telecommunications. These six components were integrated through a variety of interfaces, providing a system that works well for patients and providers. With more than 400 HTUs installed, IDEATel has demonstrated the feasibility of large-scale home telemedicine.

Columbia University's Informatics for Diabetes Education and Telemedicine (IDEATel) Project: rationale and design.

The Columbia University Informatics for Diabetes Education and Telemedicine (IDEATel) Project is a four-year demonstration project funded by the Centers for Medicare and Medicaid Services with the overall goals of evaluating the feasibility, acceptability, effectiveness, and cost-effectiveness of telemedicine in the management of older patients with diabetes. The study is designed as a randomized controlled trial and is being conducted by a state-wide consortium in New York. Eligibility requires that participants have diabetes, are Medicare beneficiaries, and reside in federally designated medically underserved areas. A total of 1,500 participants will be randomized, half in New York City and half in other areas of the state. Intervention participants receive a home telemedicine unit that provides synchronous videoconferencing with a project-based nurse, electronic transmission of home fingerstick glucose and blood pressure data, and Web access to a project Web site. End points include glycosylated hemoglobin, blood pressure, and lipid levels; patient satisfaction; health care service utilization; and costs. The project is intended to provide data to help inform regulatory and reimbursement policies for electronically delivered health care services.
