Comparison of management of minor head injuries in 2001 and 2002: admission/discharge
| 2001 (7 months) | 2002 (9 months) | Increase (95% CI) | |
|---|---|---|---|
| Numbers refer to MHI patients during the two study periods: in 2001, the RCS guidelines were in operation, and in 2002 the “Cambridge” protocol (a modification of the Canadian CT Rule). The Canadian CT rules were applied to each group to determine how many patients fulfilled the criteria for CT. *p<0.05. Data in parentheses are percentages unless otherwise stated. | |||
| Total number of patients admitted for observation | 111/330 (34) | 119/267 (45) | 10.9 (3.1 to 18.8)* |
| Total number fulfilling criteria admitted | 56/330 (17) | 68/267 (25) | 8.5 (1.9 to 15.1)* |
| Patients fulfilling criteria, scanned+admitted | 27/330 (8.2) | 31/267 (12) | 3.4 (−8.2 to 14.2) |
| Patients fulfilling criteria, not scanned+admitted | 29/330 (9) | 37/267 (14) | 5.1 (0.1 to10.2)* |
| Patients fulfilling criteria, scanned and discharged | 10/330 (3) | 9/267 (3) | 0 (−2.5 to 3.2) |
| Patients not fulfilling criteria but admitted | 63/330 (19) | 51/267 (19) | 0 (−6.3 to 6.4) |
