NHSCFA assesses how financially vulnerable the current thirteen lead thematic areas are to fraud. In order to achieve this the NHSCFA adopts a different approach depending on the nuances of the area. However broadly speaking the two main ways are;
- Loss measurement exercise - These take the form of an in-depth analysis and measurement of a particular area to provide a statistically robust percentage of how much of the funding / reimbursement is vulnerable to fraud. Out of the two methods the NHSCFA has the highest confidence in this method.
- Comparative loss assessment – Where the NHSCFA has not directly measured an area, we are reliant on vulnerability percentages derived from partners or stakeholders to use. These may not be 100% comparable so therefore the NHSCFA has the least confidence in them.
Within the strategic intelligence assessment a consistent language has been used across thematic areas when assessing the probability and uncertainty. The ‘probability yardstick’ defines the language applied to the range
In using the probability spectrum the NHSCFA has taken into account, the source, the age and reliability of the material used and any extenuating factors to form the assessment. No particular weighting is attached to specific factors but rather a holistic approach is taken when assigning the probability and uncertainty.NHSCFA probability spectrum
The probability yardstick assigns a quantitative confidence level for qualitative descriptors used within an intelligence assessment.
| Percentage range | Likelihood of occurence | |
|---|---|---|
| 0% - 5% | Remote chance | |
| 10% - 20% | Highly unlikely | |
| 25% - 35% | Unlikley | |
| 40% - 50% | Realistic possibility | |
| 55% - 75% | Likely/ probable | |
| 80% - 90% | Highly likely | |
| 95% - 100% | Almost certain |
