Randomized Controlled Trial Multicenter Study
A randomized controlled trial on Stroke telerehabilitation: The effects on falls self-efficacy and satisfaction with care.
We determined the effect of a multifaceted stroke telerehabilitation (STeleR) intervention on falls-related self-efficacy and satisfaction with care. We conducted a prospective, randomized, multisite, single-blinded trial in 52 veterans from three Veterans Affairs Medical Centers. Participants who experienced a stroke in the past 24 months were randomized to the STeleR intervention or usual care. ⋯ Core concepts identified were: (a) beneficial impact of the trained assistant; (b) exercises helpful; (c) home use of technology. The STeleR intervention improved satisfaction with care, especially as it relates to care following their experience from the hospital. With the limited resources available for in-home rehabilitation for stroke survivors, STeleR (and especially its exercise components) can be a useful complement to traditional post-stroke rehabilitation.

Randomized Controlled Trial
A randomised clinical trial of the effectiveness of home-based health care with telemonitoring in patients with COPD.
We studied the effect of telemonitoring in addition to usual care compared to usual care alone in patients with chronic obstructive pulmonary disease (COPD). A total of 110 patients with moderate to severe COPD were recruited from a specialist respiratory service in Northern Ireland. Patients had at least two of: emergency department admissions, hospital admissions or emergency general practitioner (GP) contacts in the 12 months before the study. ⋯ There were no significant between group differences in EQ-5D scores, HADS depression scores, GP activity, emergency department visits, hospital admissions or exacerbations. The total cost to the health service of the intervention over the 6-month study period was £2039, giving an estimated ICER of £203,900. In selected patients with COPD, telemonitoring was effective in improving health-related quality of life and anxiety, but was not a cost-effective intervention.

Randomized Controlled Trial
The accuracy of mobile teleradiology in the evaluation of chest X-rays.
We assessed the diagnostic accuracy of digital photographs of plain film chest X-rays (CXRs) obtained using a mobile phone. The study was a randomized, non-inferiority trial, in which physical plain film CXRs viewed on a light box were compared with digital photographs of plain film CXRs. CXRs were selected from a database of radiology studies to show common pathologies found in Botswana associated with pneumonia, lung carcinoma, tuberculosis, pneumothorax and interstitial disease, as well as normal findings. ⋯ The difference in diagnostic accuracy was -5.7% (95% CI: -10.8% to -0.5%), which confirmed non-inferiority (P<0.001) for the primary outcome of diagnostic accuracy. A subgroup analysis demonstrated non-inferiority for lung carcinoma and pneumonia images, although non-inferiority was not achieved for pneumothorax, tuberculosis, interstitial disease or normal images. The study demonstrates that digital photographs of CXRs obtained via a mobile phone equipped with a digital camera are non-inferior to plain film CXRs.

Randomized Controlled Trial Comparative Study
A pilot study of the Tele-Airway Management System in a hospital emergency department.
We developed a telemedicine system for remote guidance of emergency airway management called the Tele-Airway Management System (TAMS). In a pilot study we examined the usefulness of the TAMS for intubations of actual patients in a hospital emergency department. Twenty-five patients were allocated randomly either to a TAMS group or to an on-scene directed (OSD) group. ⋯ There were no mechanical or technical errors such as disconnection during use of the TAMS. The pilot study demonstrated the feasibility of the TAMS as an alternative to OSD. However, a larger study will be required to determine non-superiority or equivalence.

Randomized Controlled Trial
Video calls for dispatcher-assisted cardiopulmonary resuscitation can improve the confidence of lay rescuers--surveys after simulated cardiac arrest.
Many mobile phones allow two-way video communication, which permits callers to hear and see each other. If used during medical emergencies, bystanders can receive supervision and guidance from medical staff based on visual information. We investigated whether video calls from mobile phones could improve the confidence of lay rescuers. ⋯ Rescuers who had not used video phones had a greater tendency to comment on immature video call technology, while some who had used video phones complained about poor sound quality during video calls. The majority of rescuers in both groups believed that video calls were superior to audio calls during medical emergencies, and this proportion was significantly higher in the video group (P = 0.0002). We found that visual contact and supervision through video calls improved rescuers' confidence in stressful emergencies.
