Using the complication rates for each diagnostic group we predicted the complication rate expected in each location and for each physician group
| A Observed and expected complication rates for each location | |||
|---|---|---|---|
| ICU | ED | Wards | |
| Expected number of complications | 40 | 9 | 21 |
| Expected rate of complication % | 50.6 | 11.7 | 40.4 |
| Observed rate of complication % | 54.4 | 16.0 | 50.0 |
| χ2 gives a p = 01.3 | |||
| B Observed and expected complication rates for each physician group | |||
|---|---|---|---|
| Group A | Group NA | Group M | |
| χ2 gives a p = 0.23. | |||
| Expected number of complications | 18 | 27 | 28 |
| Expected rate of complication % | 35.3 | 32.9 | 37.3 |
| Observed rate of complication % | 33.3 | 34.1 | 49 |
