Treatment costs may vary across subgroups of patients with different types of pain. The aim of our study was to compare healthcare costs (HC) and resource utilization in musculoskeletal (MP), neuropathic (NP), and cancer pain (CaP) patients treated with long-acting opioids (LAO), using real-world evidence.Patients and methods: We compared total HC and resource utilization in subgroups of chronic pain patients (MP, NP or CaP) treated with three LAO alternatives: morphine-sulfate extended-release (MsER), oxycodone ER (OxnER) and tapentadol ER (TapER). Retrospective claims data were analyzed in the IBM Truven Health MarketScan® Commercial Claims Database (October 2012 through March 2016). All patients were continuously health plan enrolled for at least 12 months before the index date (ï¬rst LAO prescription date) and during the LAO-treatment period. The cohorts were propensity-score matched.Results: A total of 2824 TapER-treated patients were matched to 16,716 OxnER-treated patients, while 2827 TapER patients were matched to 16,817 MsER patients. The average monthly total HC were lower in the TapER than in the OxnER cohort ($2510 vs. $3720, p<0.001), reï¬ecting significantly lower outpatient, inpatient and emergency department visit rates in the TapER cohort. Similarly, the TapER cohort exhibited a lower average monthly total HC ($2520 vs. $2900, p<0.05) than MsER cohort, with signiï¬cantly fewer inpatient and outpatient visits in the TapER cohort. TapER demonstrated signiï¬cantly lower total HC than OxnER in patients with NP and MP, and similar to OxnER in CaP patients. TapER costs were similar to MsER costs in all pain-type subpopulations.Conclusion: Based on real-world evidence, the TapER treatment for chronic pain was associated with signiï¬cantly lower HC compared with MsER or OxnER. When categorized by type of pain, TapER remained a less costly strategy in comparison with OxnER for MP and NP.Keywords: long-acting opioids, real-world evidence, administrative database, cost analysis, subgroup analysis

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
