Degree of precision of estimates of the incidence of avoidable significant harm
| Estimated incidence of avoidable significant harm (per 100 000 patients per year) | Precision (width of 95% CI) | 95% CIs based on a sample size of 100 000 patients |
|---|---|---|
| 20 | 9 | 11 to 29 |
| 40 | 12 | 28 to 52 |
| 80 | 18 | 62 to 98 |
| 100 | 20 | 82 to 120 |
| 200 | 28 | 172 to 228 |
Bold values are the lower bound of the likely incidence.
