| Percentage time in range |
Shows the proportion of the total time during which each patient has had an INR result falling within the target range (defined as ±0.5 of the actual target). The report groups the patients into bands and these are a measure of the quality of anticoagulation control. |
| Percentage tests in range |
Shows the percentage of INR tests falling within, above and below the target INR range (Range ±0.5 INR). |
| Out-of-range |
The number of out of range results over the period of time selected. |
| Adverse Event |
The number of adverse events occurring during the selected time period. |
| Variance |
The percentage of all INR results falling within ±0.5 and ±0.75 units of the target INR. |
| Point prevalence |
The percentage of patients whose last INR result falls within 0.5 of their target INR. PP gives a clearer picture than time in range of how well your whole service is doing and the British Society of Haematology target for dosing efficiency is 60% of INR tests within 0.5 units of the target INR. |
