Outpatient video consultations are feasible but challenging for the NHS

Video consultations may be a useful substitute for face-to-face consultations for some hospital outpatient appointments. This NIHR funded study provided insights into the conditions which made them better. When these practical and clinical conditions are met, video consultations can be safe and effective and are liked by staff and patients. But there are challenges in ...

A reminder that too much oxygen increases mortality in acutely ill adults

In acutely ill adults, liberal use of oxygen supplementation is found to increase the risk of death compared with more conservative oxygen strategies. More liberal oxygen therapy increases patient mortality in hospital by about 11 deaths amongst every 1,000 people exposed. Deaths also increase after 30 days follow-up, without improving other important health outcomes, such ...

School-based self-regulation interventions can improve child academic, health and behavioural outcomes

Different types of interventions improve self-regulation in children and young people, which helps children to manage their behaviour and emotions. School curriculum-based interventions show the most consistently positive results. Interventions also improve longer-term academic, health and social outcomes. Self-regulation encompasses a range of skills, including controlling your own emotions, interacting positively with others, avoiding inappropriate ...

Ultrasound shows potential for confirming the diagnosis of pneumonia in children

Ultrasound scans of the lungs can be more accurate than chest X-rays for diagnosing pneumonia in children in some circumstances. A review of the published evidence found that lung ultrasound was more sensitive (missed fewer cases) and about as specific (gave about the same number of false alarms) as chest X-ray, when used to confirm ...

Enhanced recovery programmes after stomach cancer surgery reduce hospital stay without increasing complications

Enhanced recovery programmes reduce length of hospital stay and associated healthcare costs after stomach cancer surgery, with no impact on short-term mortality or post-operative complications. They also improve post-operative quality of life. The enhanced recovery approach includes a range of components designed to help people to recover more quickly and have better outcomes after surgery. These ...

Varicose vein injections help new venous leg ulcers heal

For patients with leg ulcers caused by varicose veins, early intervention to treat the veins results in faster healing of ulcers than standard compression therapy alone. Researchers studied 450 people with open venous leg ulcers of 6 weeks to 6 months duration and varicose veins. Those assigned to have their veins treated within two weeks ...

Structured training improves skills of wheelchair users

Structured wheelchair skills training increases wheelchair users’ skills when compared with no training, standard care or education controls. The training, as developed in Canada, is more effective for new wheelchair users than experienced users. It includes difficult everyday challenges from wheeling through gravel to negotiating high curbs. Links have been found previously between wheelchair skills ...

Gallbladder surgery through a single-incision is more risky than a multiple incision technique

Single-incision keyhole gallbladder removal surgery carries increased risk of adverse events, such as puncturing the gallbladder, compared with the more standard multiple-incision procedures. However, in experienced hands, there may be benefits such as reduced pain and less scarring after the operation. Current guidance recognises that using a single incision for laparoscopic cholecystectomy is more complex ...

Increasing inhaled steroids for short periods reduces asthma exacerbations

Taking four times the usual dose of inhaled corticosteroids for up to two weeks can modestly reduce the chance of asthma worsening. This NIHR-funded trial assessed increasing the inhaled corticosteroid dose compared with staying on the usual dose, as part of a self-management plan. Participants were adults and adolescents with uncontrolled asthma and had at ...

Testing oxygen levels of newborn babies helps find serious heart defects

Measuring oxygen levels in newborn babies as part of routine care can identify cases of critical congenital heart defects sooner than waiting until symptoms appear. If 10,000 babies were screened, pulse oximetry could correctly identify about 5 of the 6 expected asymptomatic cases and might miss one. This international research suggests there would be about ...
