Medication impregnated dressings for central venous catheters reduce the number of bloodstream infections, but the quality of the research is low

This review found that securing central venous catheters with dressings impregnated with medication reduced the number of bloodstream infections compared to other dressings. The frequency of infection was particularly reduced with chlorhexidine antiseptic dressings. Based on the study population it is anticipated that rates might fall from about 2.8 infections per 100 people using usual ...

Rapid tests for diagnosing drug resistant tuberculosis are accurate and may be cost effective

This NIHR funded systematic review and economic evaluation found that three rapid tests for diagnosing drug resistant tuberculosis were highly accurate and likely to be cost effective in the UK. These tests produce results within one day of obtaining a sample. This is a significant reduction compared with the standard tests which can take about ...

New evidence available on corticosteroids added to antibiotics in severe pneumonia

For adults admitted to hospital with severe pneumonia, this review found that adding corticosteroids to the usual antibiotic treatment may be beneficial. The evidence was less supportive of using corticosteroids in people with less severe pneumonia. Results showed modest benefits in allowing patients to reach a clinically stable recovery and leave hospital an average of ...

Electrical stimulation alongside other treatments may slightly improve ankle spasticity after stroke, but the clinical importance is uncertain

This systematic review and meta-analysis found that electrical stimulation produced a small, but statistically significant improvement, in tight muscles (spasticity) for people recovering from stroke. The clinical importance of the improvement is uncertain. For example, electrical stimulation improved joint flexibility by an average of 2.87 degrees and spasticity improved by 0.3 on a 5 point ...

A new, simple postural manoeuvre can stop an abnormally fast heart rate

A simple postural change to the Valsalva manoeuvre (see Definitions) improves the effectiveness of this cheap, non-invasive means of treating supraventricular tachycardia - an abnormally fast heart rate over 100 beats per minute. The NIHR funded a pragmatic trial of the promising technique in ten hospital emergency departments in England. The trial found that laying ...

A behavioural intervention for obese pregnant women did not reduce risk of diabetes

This large NIHR-funded UK trial found that a behavioural intervention for obese pregnant women did not reduce their risk of developing diabetes during pregnancy, or having a baby born too large for the duration of pregnancy (large-for-dates). However, the intervention did reduce the mothers’ weight gain slightly and increased their physical activity. Women received advice ...

Listening to music reduces pain and anxiety for patients having surgery

This systematic review found that music can moderately reduce pain and anxiety when played before, during or after surgery. It also strongly increased patient satisfaction. Music was equally effective whether chosen by the patient or not. It was most effective when played before surgery and when the patient was conscious, though it was still effective ...

Inhaling a saline mist did not reduce the time in hospital for babies with bronchiolitis

In this NIHR-funded trial babies with a viral chest infection (acute bronchiolitis) were treated either with a strong saline mist (nebulised 3% hypertonic sodium chloride) with standard care or standard care alone. The stronger than usual, hypertonic saline mist had no effect on the time it took for babies to be ready for discharge, nor ...

A coping programme moderately reduces depression and anxiety in carers of people with dementia

This NIHR-funded trial found that a programme to support carers of people with dementia was moderately effective in reducing carers’ depression and anxiety scores for up to two years. It was also cost-effective. The programme consisted of eight sessions delivered by psychology graduates, covering topics such as managing difficult behaviour, accessing support and planning for ...

Education can restore awareness of low blood glucose in people with type 1 diabetes

This systematic review found that a range of educational and technological interventions could help adults with type 1 diabetes regain awareness of when they have low blood glucose (hypoglycaemia). Nearly one in every three adults with type 1 diabetes stops noticing low blood sugar levels. This means they cannot take action quickly to prevent a ...
