Randomized Controlled Trial
Implementation of virtual reality technology to decrease patients' pain and nervousness during colonoscopies: a prospective randomised controlled single-blinded trial.
Improved patient satisfaction in endoscopy is worthy of study as it is an invasive and potentially uncomfortable procedure. There is growing literature on patient satisfaction assessment in endoscopy as part of improving quality assurance. This study aimed to determine whether virtual reality (VR) technology can decrease patients' pain and nervousness during colonoscopies. ⋯ VR technology helped to reduce patients' pain and nervousness and to improve patients' satisfaction during colonoscopies.

Randomized Controlled Trial
The unspoken benefit of participation in a clinical trial.
Publicly funded trials do not usually offer financial incentives to volunteers. An intensive level of medical care could act as an additional motivator for participation. Our aim was to establish whether patients may draw any clinical benefit from volunteering in a clinical trial. ⋯ Compared with routine care, patients screened for a clinical trial may come under an increased level of scrutiny that may affect their clinical management. This may act as additional motivator to attract patients to future studies.

Randomized Controlled Trial
The effect of ivabradine on functional capacity in patients with chronic obstructive pulmonary disease.
Increased sympathetic tone and use of bronchodilators increase heart rate and this may worsen functional capacity in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to look at the short-term effect of the heart rate lowering drug ivabradine on clinical status in COPD patients. We randomised 80 COPD patients with sinus heart rate ≥90 bpm into either taking ivabradine 7.5 mg twice per day or placebo for two weeks. ⋯ The ivabradine group showed significant improvement in 6-minute walk distance (from 192.6±108.8 m at baseline to 285.1±88.9 m at the end of the study) compared with the control group (230.6±68.4 at baseline and 250.4±65.8 m at the end of study) (p<0.001). This improvement in the drug group was associated with significant improvement of dyspnea on modified Borg scale (p=0.007). Lowering heart rate with ivabradine can improve exercise capacity and functional class in COPD patients with resting heart rate >90 bpm.

Randomized Controlled Trial
Randomised controlled trial of GP-led in-hospital management of homeless people ('Pathway').
Homeless people have complex problems. GP enhanced care (Pathway) has shown benefits. We performed a randomised, -parallel arm trial at two large inner city hospitals. ⋯ The proportion of people sleeping on the streets after discharge was 14.6% in the standard care arm and 3.8% in the enhanced care arm (p=0.034). The quality-of-life cost per quality-adjusted life-year was £26,000. The Pathway approach doesn't alter length of stay but improves quality of life and reduces street -homelessness.
