Level 4 equivalent of 2014
Level 4 equivalent, abbreviated L4E, is a workload measurement system endorsed by the Canadian Association of pathologists.[1]
The development is described in a paper by Maung published in 2010.[2] The system was revised in 2014 and is comprehensive with regard to academic practice and community practice.[3]
This article covers the 2014 revision of L4E. The original system is covered in the article Level 4 equivalent of 2010.
Revised L4E of 2014
Most surgical pathology
As per L4E definition (2014) adapted from CAP-ACP:[4]
| Code | L4E units | Description | Details |
|---|---|---|---|
| L1 | 0.15 | gross only specimens | itemized in the "specimen list and codes" |
| L2 | 0.333 | confirmation of normal | must include histology |
| L3 | 0.5 | small/simple biopsies | includes most skin, cysts, GI tract specimens, small benign specimens |
| L4 | 1 | biopsies - most internal organs | detailed in rules 1, 2 and 3 |
| L5 | 5 | complex biopsies - includes medical and transplant biopsies, explant organs | |
| L6 | 10 | radical resections for malignancy | detailed in rule 9 |
All other surgical pathology cases
As per L4E definition (2014) adapted from CAP-ACP:[4]
| L4E units | Description | Details |
|---|---|---|
| L2/block | non-radical and benign resections, non-biopsy/non-L6 cases | detailed by rule 4, e.g. 10 blocks = 10 x L2; 10 x L2 = 3.33 L4Es |
Cytopathology
As per L4E definition (2014) adapted from CAP-ACP:[4]
| Code | L4E units | Description | Details |
|---|---|---|---|
| C1 | 1 | simple (exfoliative) cytology | pap test, urine, sputum, fluids (peritoneal, pleural) |
| C2 | 2 | complex cytology | FNAs, brushes, washes |
Total workload
Recommended workload per pathologist:[4]
| Mean annual L4E units | Lower bound ‡ | Upper bound ‡ |
|---|---|---|
| 7560 | 7115 | 8089 |
‡ Defined by mean +/- 2 standard deviations.
