Multicenter Study
Review of patient safety incidents reported from critical care units in North-West England in 2009 and 2010.
We categorised and established the rates of patient safety incidents reported during 2009 and 2010 from critical care units in 12 hospital trusts in North-West England. We identified a total of 4219 incidents reported during 127, 467 calendar days of critical care with a median (IQR [range]) of 31 (26-45 [20-57]) incidents per 1000 days per trust. A median (IQR [range]) of 10 (7-13 [3.5-27]) incidents per 1000 days were associated with harm. ⋯ Five incidents described the use of inappropriate arterial flush solutions. It is possible to compare rates of incident reporting in different trusts over time to determine if different methods of care are associated with different reporting rates. The wide range of reported pressure sore rates suggests that their incidence could be reduced.

Randomized Controlled Trial
Does targeted pre-load optimisation by stroke volume variation attenuate a reduction in cardiac output in the prone position.
The prone position can reduce cardiac output by up to 25% due to reduced preload. We hypothesised that preload optimisation targeted to stroke volume variation before turning prone might alleviate this. ⋯ In 45 patients, cardiac output declined only in the group whose supine stroke volume variation was high (mean (SD) 5.1 (2.0) to 3.9 (1.9) l.min(-1) ; p < 0.001), but not in patients in whom it was low, or in those in whom stroke volume variation was high, but who received volume preload (p = 0.525 and 0.941, respectively). We conclude that targeted preload optimisation using a supine stroke volume variation value < 14% is effective in preventing falls in cardiac output induced by the prone position.
