Context: Telemedicine is a promising but largely unproven technology for providing case management services to patients with chronic conditions and lower access to care.
Objectives: To examine the effectiveness of a telemedicine intervention to achieve clinical management goals in older, ethnically diverse, medically underserved patients with diabetes.
Design, Setting, and Patients: A randomized controlled trial was conducted, comparing telemedicine case management to usual care, with blinded outcome evaluation, in 1,665 Medicare recipients with diabetes, aged ≥ 55 years, residing in federally designated medically underserved areas of New York State.
Interventions: Home telemedicine unit with nurse case management versus usual care.
Main Outcome Measures: The primary endpoints assessed over 5 years of follow-up were hemoglobin A1c (HgbA1c), low density lipoprotein (LDL) cholesterol, and blood pressure levels.
Results: Intention-to-treat mixed models showed that telemedicine achieved net overall reductions over five years of follow-up in the primary endpoints (HgbA1c, p = 0.001; LDL, p < 0.001; systolic and diastolic blood pressure, p = 0.024; p < 0.001). Estimated differences (95% CI) in year 5 were 0.29 (0.12, 0.46)% for HgbA1c, 3.84 (−0.08, 7.77) mg/dL for LDL cholesterol, and 4.32 (1.93, 6.72) mm Hg for systolic and 2.64 (1.53, 3.74) mm Hg for diastolic blood pressure. There were 176 deaths in the intervention group and 169 in the usual care group (hazard ratio 1.01 [0.82, 1.24]).
Conclusions: Telemedicine case management resulted in net improvements in HgbA1c, LDL-cholesterol and blood pressure levels over 5 years in medically underserved Medicare beneficiaries. Mortality was not different between the groups, although power was limited.

    • "Over half of the research participants represented in the meta-analysis came from a single trial (the IDEATel trial), which recruited 1,665 participants from medically underserved areas of New York State. In this trial, the improvements in HbA1c associated with telehealth were sustained over five years, and amounted to 0.29% at the end of that period (3.2 mmol/mol) [11-13]. IDEATel, however, began recruiting participants in 2002 when telehealth was relatively new. "

    ABSTRACT: The Whole Systems Demonstrator was a large, pragmatic, cluster randomised trial that compared telehealth with usual care among 3,230 patients with long-term conditions in three areas of England. Telehealth involved the regular transmission of physiological information such as blood glucose to health professionals working remotely. We examined whether telehealth led to changes in glycosylated haemoglobin (HbA1c) among the subset of patients with type 2 diabetes. The general practice electronic medical record was used as the source of information on HbA1c. Effects on HbA1c were assessed using a repeated measures model that included all HbA1c readings recorded during the 12-month trial period, and adjusted for differences in HbA1c readings recorded before recruitment. Secondary analysis averaged multiple HbA1c readings recorded for each individual during the trial period. 513 of the 3,230 participants were identified as having type 2 diabetes and thus were included in the study. Telehealth was associated with lower HbA1c than usual care during the trial period (difference 0.21% or 2.3 mmol/mol, 95% CI, 0.04% to 0.38%, p = 0.013). Among the 457 patients in the secondary analysis, mean HbA1c showed little change for controls following recruitment, but fell for intervention patients from 8.38% to 8.15% (68 to 66 mmol/mol). A higher proportion of intervention patients than controls had HbA1c below the 7.5% (58 mmol/mol) threshold that was targeted by general practices (30.4% vs. 38.0%). This difference, however, did not quite reach statistical significance (adjusted odds ratio 1.63, 95% CI, 0.99 to 2.68, p = 0.053). Telehealth modestly improved glycaemic control in patients with type 2 diabetes over 12 months. The scale of the improvements is consistent with previous meta-analyses, but was relatively modest and seems unlikely to produce significant patient benefit.

    • "In the Informatics for Diabetes Education and Telemedicine (IDEATel) study,32 1,665 middle-aged Medicare recipients with diabetes were randomized to usual care or an intervention with a home telemedicine unit used for web access, videoconferencing with a health care professional and monitoring of glucose and BP. After 12 months, SBP and DBP were respectively lower in the intervention group (3.4 mmHg [P = 0.001] and 1.9 mmHg [P < 0.001]). "

    ABSTRACT: Hypertension is a major modifiable risk factor for cardiovascular, retinal, and kidney disease. In the past decade, attainment rates of treatment targets for blood pressure control in the UK and US have increased; however, <11% of adult men and women have achieved adequate blood pressure control. Technological advances in blood pressure measurement and data transmission may improve the capture of information but also alter the relationship between the patient and the provider of care. Telemonitoring systems can be used to manage patients with hypertension, and have the ability to enable best-practice decisions more consistently. The improvement in choice for patients as to where and who manages their hypertension, as well as better adherence to treatment, are potential benefits. An evidence base is growing that shows that telemonitoring can be more effective than usual care in improving attainment rates of goal blood pressure in the short-to-medium term. In addition, studies are in progress to assess whether this technology could be a part of the solution to address the health care needs of an aging population and improve access for those suffering health inequalities. The variation in methods and systems used in these studies make generalizability to the general hypertension population difficult. Concerns over the reliability of technology, impact on patient quality of life, longer-term utility and cost-benefit analyses all need to be investigated further if wider adoption is to occur.

    • "Controlling BP is felt to be one of the most cost-effective interventions for improving the health of persons with diabetes and hypertension , yet control of hypertension in persons with diabetes remains inadequate [5] [6] [7] [8]. While others have approached control of hypertension using home self-monitoring and manual reporting, telephonic uploading, custom home equipment including a computer and video link along with a dedicated case manager [9], custom web portals [10], or clinical pharmacists [11] [12], the CONDUIT intervention uses existing nurses (RNs) and medical assistants (MAs), staff already employed in virtually all practice settings, a low-cost BP monitor, and a free online application. The study will evaluate, via a randomized controlled trial (RCT) of 400 patients, whether this low-cost CHI intervention improves clinical outcomes for this patient population. "

    ABSTRACT: The CONDUIT-HID intervention integrates patients’ electronic blood pressure measurements directly into the clinical EHR using Microsoft HealthVault as an intermediary data store. The goal of this paper is to describe generalizable categories of patient and technical challenges encountered in the development and implementation of this inexpensive, commercial off-the-shelf consumer health informatics intervention, examples of challenges within each category, and how the example challenges were resolved prior to conducting an RCT of the intervention.
