Determinants of hospital costs associated with traumatic brain injury in England and Wales.
Using data from the Trauma Audit Research Network, we investigated the costs of acute care in patients > or = 18 years of age hospitalised for traumatic brain injury between January 2000 and December 2005 in England and Wales. Traumatic brain injury patients were defined and stratified using the Abbreviated Injury Scale. A total of 6484 traumatic brain injury patients were identified; 22.3% had an Abbreviated Injury Scale score of three, 38.0% of four and 39.7% of five. ⋯ In total 23.7% of the patients died before discharge. Hospitalisation costs averaged 15,462 pounds sterling (SD 16,844 pounds sterling). Costs varied significantly by age, Glasgow Coma Score, Injury Severity Score, coexisting injuries of the thorax, spine and lower limb, hospital mortality, availability of neurosurgical services, and specialty of attendants seen in the Accident and Emergency department.

Multicenter Study
A prospective observational study of ICU patient position and frequency of turning.
Positioning and turning critically ill patients may be beneficial but there are little data on current practice. We prospectively recorded patient position every hour over two separate days in 40 British intensive care units and analysed 393 sets of observation. Five patients were prone at any time and 3.8% (day 1) and 5% (day 2) were on rotating beds. ⋯ The average time (SD) between turns was 4.85 (3.3) h. There was no significant association between the average time between turns and age, weight, height, gender, respiratory diagnosis, intubated and ventilated, sedation score, day of week or nurse:patient ratio. There was a significant difference between hospitals in the frequency with which patients were turned.

We have investigated the suitability of the HemoCue photometer to measure the concentration of haemoglobin in suction fluid obtained at elective caesarean section in 30 women. Laboratory analysis was used as a gold standard against which values generated by the HemoCue were compared. ⋯ Mean (SD) total blood loss calculated using these data, combined with the weight of the swabs, was consistently greater than clinical estimation: 768 (496) ml versus 506 (249) ml respectively (p < 0.001). We have found that the HemoCue near patient testing device may be used to estimate blood loss accurately in the suction fluid obtained at elective Caesarean section.
