This NIHR-funded study estimated the long-term cost effectiveness of using two recommended blood tests – glycated haemoglobin or fasting blood glucose - to detect type 2 diabetes during NHS health checks. Several screening strategies were tested. In most cases the glycated haemoglobin test was more likely to be cost effective than a fasting blood glucose. ...

Self-monitoring of warfarin is safe and cost-effective

This NIHR-funded systematic review investigated the clinical and cost-effectiveness of self-monitoring by people receiving long-term anticoagulation using vitamin K antagonists, most commonly, warfarin. People receiving warfarin require regular blood tests to see how their blood is clotting and to adjust their dose to avoid bleeding from too high a dose or thrombosis (clots) if the ...

This systematic review of trials found that resveratrol supplements do not improve the results of tests that indicate risk of heart disease, including levels of blood pressure, blood glucose, cholesterol or C-reactive protein. Resveratrol is found naturally in red grapes, other fruits, and nuts. Some researchers think resveratrol in red wine may lower the risk ...

About a quarter of stroke survivors in the UK cannot return ...

Same day treatment of uterine polyps in outpatients is no worse than inpatient treatment and better value for money

This NIHR-funded trial compared treatment of uterine polyps under local anaesthetic at the time of diagnosis in a hospital outpatient clinic with inpatient treatment under general anaesthetic on another day. Treatment success, as determined by women’s assessment of bleeding, was no worse in the clinic treated group, using a pre-determined threshold for an important difference. ...

Continuous positive airway pressure led to less daytime sleepiness in older adults with sleep apnoea

This NIHR trial found that continuous positive airway pressure for obstructive sleep apnoea in people aged 65 and over led to less daytime sleepiness and was reasonable value for money. Obstructive sleep apnoea causes the airway to close intermittently overnight leading to daytime sleepiness. It is most common in older people, but previous studies have ...
