In this study, 24 NHS hospitals in the Northwest of England were randomly allocated to participate either in Stroke 90:10, a quality improvement collaborative (QIC) based on the IHI Breakthrough Series (BTS) model, or in a control group giving normal care. Some aspects of stroke care modestly improved during the collaborative. The extent to which a BTS QIC can improve quality of stroke care remains uncertain, as some aspects of care may respond better to collaboratives than others.
