- CDC Clinical Practice Guideline (2022) – MME table: hydrocodone (1), hydromorphone (5), oxycodone (1.5), oxymorphone (3), general MME methodology; fentanyl patch ≈2.4 µg/h per 1 mg OME.
- ANZCA FPM PS01 Appendix (2021): parenteral factors: fentanyl (0.2 µg), sufentanil (2 µg), codeine (0.25 mg), pethidine (0.4 mg), morphine (3 mg), oxycodone (3 mg), hydromorphone (15 mg).
- Community Care of North Carolina / Utah Medicaid: tapentadol 0.40; tramadol 0.1–0.2 across programs.
- Scottish Palliative Care: fentanyl patches: 25 µg/h ≈ 60–90 mg oral morphine/24 h (supports ~2.4 factor).
- Buprenorphine (sublingual) shown in µg with factor 0.08 (equivalent to 80 per mg) for internal consistency; many official MME tables exclude SL bupe from equianalgesic conversion — interpret cautiously.
