Improving Opioid Prescribing Post-Discharge for Trauma Patients With Rib Fractures: Factors in Prevention of Prolonged Use and Dependency

Background Rib fracture (RF) pain management provides analgesia while reducing opioids. We postulated: (1) Prescriber factors affect opiate duration, and (2) lidocaine infusion curtails dependency. Materials and Methods Retrospective study of RF patients undergoing multimodal analgesia at ACS-verified Level 1 Trauma Center April 2018-February 2020. Exclusions: age<18 y/o, GCS < 14, hospital length of stay (LOS) <3 d, <3 RF, ventilator support, injury-related mortality, disclosed/discoverable, acute/chronic opiate Rx within 90 days preadmission, substance abuse, patient inaccessible via Controlled Substance Monitoring Database (CSMD), and/or not using opioids in-/post-hospitalization. CSMD queried regarding opioid prescriptions filled by cohort. Cohort variable analysis performed on SPSS Version 27sf (Armonk, NY: IBM Corp). Results 153 patients included - 113 (74%) stopped opiates by 30 days post-discharge (NORx30), 40 (26%) continued beyond 30 days (Rx+). No significant differences in age, gender, ISS, number of RF, bilaterality, flail chest, and discharge disposition. Significant differences included hospital LOS (7.62 NORx30 vs. 10.22 Rx+, p = .02), number of prescribers (1.73 NORx30 vs. 2.98 Rx+, p < .01), average MME/day during initial 30 days post-discharge (36.7 +/- 17 NORx30 vs. 45.4 +/- 30.2 Rx+, p = .03), and number of pills (49 +/- 38 NORx30 vs. 120 +/- 85 Rx+, p < .01). Patients who received lidocaine infusion (LIDO+) had lower MME/day prescribed (32.24 +/- 19.9, p = .03), were younger (61.2 vs. 65.6, p < .01), had more RFs (7.1 vs. 6.05, p = .03), and shorter LOS (7.71 vs 10.2, p = .01). Discussion Prescriber attention to MME/day and number of pills dispensed affects opioid dependency. We recommend 35-40 MME/day with 50 pill/month limit prescribed by a single provider monitoring patient and CSMD. Early LI offers post-discharge opioid cessation advantage.
