Review Meta AnalysisAudit and feedback: effects on professional practice and healthcare outcomes.
Audit and feedback is widely used as a strategy to improve professional practice either on its own or as a component of multifaceted quality improvement interventions. This is based on the belief that healthcare professionals are prompted to modify their practice when given performance feedback showing that their clinical practice is inconsistent with a desirable target. Despite its prevalence as a quality improvement strategy, there remains uncertainty regarding both the effectiveness of audit and feedback in improving healthcare practice and the characteristics of audit and feedback that lead to greater impact. ⋯ Audit and feedback generally leads to small but potentially important improvements in professional practice. The effectiveness of audit and feedback seems to depend on baseline performance and how the feedback is provided. Future studies of audit and feedback should directly compare different ways of providing feedback.

Review Meta AnalysisSecond trimester serum tests for Down's Syndrome screening.
Down's syndrome occurs when a person has three copies of chromosome 21 - or the specific area of chromosome 21 implicated in causing Down's syndrome - rather than two. It is the commonest congenital cause of mental retardation. Noninvasive screening based on biochemical analysis of maternal serum or urine, or fetal ultrasound measurements, allows estimates of the risk of a pregnancy being affected and provides information to guide decisions about definitive testing. ⋯ Tests involving two or more markers in combination with maternal age are significantly more sensitive than those involving one marker. The value of combining four or more tests or including inhibin have not been proven to show statistically significant improvement. Further study is required to investigate reduced test performance in women aged over 35 and the impact of differential pregnancy loss on study findings.

ReviewSodium bicarbonate supplements for treating acute kidney injury.
Acute kidney injury (AKI) is a common, serious, but potentially treatable condition. Because AKI is often associated with acidosis, it has become common practice to recommend administration of sodium bicarbonate to correct acid imbalance. ⋯ We found no RCT evidence - supportive or otherwise - for the use of sodium bicarbonate for people with AKI. We concluded that there is an urgent need for well conducted RCTs in this area.
