Alarm strategy | Description |
---|---|
N > 95th percentile | Number of ED respiratory visits is too high |
N > 95th percentile, by season | Number of visits is too high, separate values by season |
M > 95th percentile | M statistic is too high |
M > 95th percentile, by season | M statistic is too high, separate values for each season |
MN > 95th percentile | Calculate M × N, value is too high |
N and MN rules | N is too high (top 0.5% distribution) Or M × N is too high (top 0.5% distribution) Or both N is high (>80%) and M × N is high (>80%) |
