The impact of preoperative tramadol-only use on outcomes following total knee arthroplasty - Is tramadol different than traditional opioids?

Tramadol use before total shoulder arthroplasty: patients have lower risk of complications and resource utilization than those using traditional opioids

BACKGROUND

Evidence continues to mount for the deleterious effects of preoperative opioid use in the setting of total shoulder arthroplasty (TSA). Tramadol, a synthetic opioid with concomitant neurotransmitter effects, has become a popular alternative to traditional opioids, but it has not been well studied in the preoperative setting of TSA. The purpose of this study is to evaluate postsurgical outcomes in TSA for patients with preoperative tramadol use compared with patients using traditional opioids and those who were opioid naïve.

METHODS

Using the IBM Watson Health MarketScan databases, a retrospective cohort study was performed for patients who underwent TSA from 2009 to 2018. Filled pain prescriptions were collected, and prescribing trends were analyzed. Outcomes were compared between 4 patient cohorts defined by preoperative analgesia use-opioid naïve, tramadol, traditional opioids, and combination (opioids and tramadol). Multivariate analysis was used to account for small variations in cohort demographics and comorbidities. Analysis focused on resource utilization and complications. Revision rates at 1 and 3 years postoperatively were also compared.

RESULTS

A total of 29,454 TSA patients were studied, with 8959 available for 3-year postoperative follow-up. Of these, 10,462 (35.5%) were prescribed traditional opioids and 2214 (7.5%) tramadol only. From 2009 to 2018, prescribing trends in the United States demonstrated a significant decrease in the number of patients prescribed preoperative narcotics, whereas the number of patients prescribed preoperative tramadol and those who were opioid naïve significantly increased. Compared with opioid-naïve patients, the traditional opioid cohort had significantly increased odds of resource utilization and complications, whereas the tramadol cohort did not. Specifically, the traditional opioid cohort had an increased risk of prosthetic joint infection compared with both opioid-naïve and tramadol cohorts. The traditional opioid cohort had higher revision rates than opioid-naïve patients at 1 and 3 years, whereas the tramadol cohort did not.

CONCLUSION

Despite a decrease in opioid prescriptions over the study period, many patients in the United States remain on opioids. Although tramadol is not without its own risks, our results suggest that patients taking preoperative tramadol as an alternative to traditional opioids for glenohumeral arthritic pain had a lesser postoperative risk profile, comparable with opioid-naïve patients.

Impact of Chronic Opioid Use on Postoperative Mobility Recovery and Patient-Reported Outcomes: A Propensity-Matched Study

BACKGROUND

Opioid use prior to total joint arthroplasty may be associated with poorer postoperative outcomes. However, few studies have reported the impact on postoperative recovery of mobility. We hypothesized that chronic opioid users would demonstrate impaired objective and subjective mobility recovery compared to nonusers.

METHODS

A secondary data analysis of a multicenter, prospective observational cohort study in which patients used a smartphone-based care management platform with a smartwatch for self-directed rehabilitation following hip or knee arthroplasty was performed. Patients were matched 2:1 based on age, body mass index, sex, procedure, Charnley class, ambulatory status, orthopedic procedure history, and anxiety. Postoperative mobility outcomes were measured by patient-reported ability to walk unassisted at 90 days, step counts, and responses to the 5-level EuroQol-5 dimension 5-level, compared by Chi-square and student's t-tests. Unmatched cohorts were also compared to investigate the impact of matching.

RESULTS

A total of 153 preoperative chronic opioid users were matched to 306 opioid-naïve patients. Age (61.9 ± 10.5 versus 62.1 ± 10.3, P = .90) and sex (53.6 versus 53.3% women, P = .95) were similar between groups. The proportion of people who reported walking unassisted for 90 days did not vary in the matched cohort (87.8 versus 90.7%, P = .26). Step counts were similar preoperatively and 1-month postoperatively but were lower in opioid users at 3 and 6 months postoperatively (4,823 versus 5,848, P = .03). More opioid users reported moderate to extreme problems with ambulation preoperatively on the 5-level EuroQol-5 dimension 5-level (80.6 versus 69.0%, P = .02), and at 6 months (19.2 versus 9.3%, P = .01).

CONCLUSIONS

Subjective and objective measures of postoperative mobility were significantly reduced in patients who chronically used opioid medications preoperatively. Even after considering baseline factors that may affect ambulation, objective mobility metrics following arthroplasty were negatively impacted by preoperative chronic opioid use.

The Effect of Preoperative Tramadol Use on Postoperative Opioid Prescriptions After Primary Total Hip and Knee Arthroplasty: An Institutional Experience of 11,000 Patients

BACKGROUND

Preoperative opioid use increases opioid consumption postoperatively, but the effect of tramadol is poorly understood.

METHODS

We retrospectively reviewed 11,667 patients undergoing primary unilateral THA and TKA at a single institution. Preoperatively, there were 8,201 opioid-naïve patients (70.3%), 1,315 on tramadol (11.3%), 1,408 on narcotics (12.1%) and 743 on narcotics and tramadol (6.3%). We compared morphine milligram equivalents (MMEs) used during hospitalization, prescribed at discharge, and refilled during the first 90 days. We used multivariate analysis to assess whether preoperative tramadol use was associated with increased number of refills and total refilled MMEs.

RESULTS

Total in-hospital MMEs and daily MMEs was lowest for the opioid naïve patients and significantly increased for the remaining three groups (total in-hospital use: 119, 152, 211, and 196 MMEs, respectively-P < .001) (daily in-hospital use: 66, 74, 100, and 86 MMEs, respectively-P < .001). Opioid refill rate was significantly higher for all patients who were not opioid naïve (32%, 42%, 41%, and 52%, respectively-P < .001). Total MMEs prescribed after discharge was lowest for opioid naïve patients (477, 528, 590 and 658, respectively-P < .001). Logistic and linear regression controlling for age, sex, history of anxiety/depression revealed that THA patients taking tramadol preoperatively were 2.5 times more likely to require post-discharge refills and refilled 80 additional MMEs than opioid naïve patients (P < .001).

CONCLUSION

Tramadol is not recommended for pain beforeTKA or THA, and surgeons and patients should be aware that it is associated with a substantial increase in postoperative opioid use.

A Repeat Dose of Perioperative Dexamethasone Can Effectively Reduce Pain, Opioid Requirement, Time to Ambulation, and In-Hospital Stay After Total Hip Arthroplasty: A Prospective Randomized Controlled Trial

BACKGROUND

The ideal dose of intravenous glucocorticoids to control pain in total hip arthroplasty (THA) remains unclear. This randomized controlled trial compared postoperative pain and tramadol requirement in patients undergoing unilateral primary THA who received one versus two perioperative doses of dexamethasone.

METHODS

Patients consented to undergo blinded, simple randomization to either one (at anesthetic induction [1D-group]: 54 patients) or two (with an additional dose 8 hours after surgery [2D-group]: 61 patients) perioperative doses of 8-mg intravenous dexamethasone. Pain was evaluated with visual analog scale at 8, 16, and 24 hours postoperatively and with tramadol requirement. The secondary outcomes included postoperative nausea and vomiting, time to ambulation, and length of stay.

RESULTS

Age (mean, 66 ± 13 years), body mass index (mean, 29 ± 5), gender (60% female), and history of diabetes were similar between groups (P >.05). Pain was higher at 16 (4 [interquartile range {IQR} 3-5] vs 2 [IQR 1-3]; P <.001) and 24 (2.5 [IQR 2-3] vs 1 [IQR 0-1] P <.001) hours postoperatively in the 1D-group patients. 1D-group patients had significantly more tramadol consumption (50 [IQR 50-100] vs 0 [IQR 0-50]; P = .01), as well as postoperative nausea and vomiting (18 [33.3%] vs 5 [8.2%]; P = .001). Fifty-five (90%) patients in the 2D-group and 32 (59%) in the 1D-group ambulated on postoperative day 0 (P = .0002). Fifty-eight (95%) patients in the 2D-group and 37 (68%) in the 1D-group were discharged on postoperative day 1 (P = .0002).

CONCLUSION

An additional dose of dexamethasone at 8 hours postoperatively significantly reduced pain, tramadol consumption, time to ambulation, and length of stay after primary THA.

Drug Utilization for Pain Management during Perioperative Period of Total Knee Arthroplasty in China: A Retrospective Research Using Real-World Data

Background and Objective: Total knee arthroplasty (TKA) is one of the most painful procedures and perioperative pain usually requires the use of many analgesics to relieve it. The appropriate use of analgesics to relieve patient pain is an important issue of TKA. To characterize the drug utilization for pain management during perioperative period of TKA in China using real-world data of electronic medical records. Materials and Methods: This research used the data of all inpatients who received TKA at 145 hospitals covered 31 provinces in China from 1 January 2016 to 31 December 2018. The exclusion criteria included pregnancy and cancer diagnosis. In the analysis of drug utilization mode (DUM), medicines were classified into 5 groups: non-steroidal anti-inflammatory drugs (NSAIDs), opioids, non-opioid central analgesics, acetaminophen and others. Results: Among the 2017 patients included in this study, there were 1537 (76.20%) female and 480 (23.80%) male, aged 65.77 ± 7.73 years. Regarding the surgery characteristics, 1658 (82.20%) were unilateral; 1220 (60.49%) was graded Level 4; 1312 (65.05%) used local anesthesia as the main anesthesia method, and 1450 (71.89%) lasted for more than 2 h. The most common DUM was “NSAIDs + opioids” (55.92%), followed by “NSAIDs only” (17.85%), and “NSAIDs + Opioids + Non-opioid central analgesics” (17.15%). The results of the Chi-square test showed that differences in DUM were associated with surgery types, surgery levels, surgery duration, and types of anesthesia used. Up to 81.14% of the total drug expenses for pain management was spent on NSAIDs. Due to the limitation of database, this study could not subdivide operation stages, anesthesia methods, dosage forms of drugs. Conclusion: In China, the use of analgesics in perioperative period of TKA was diversified and influenced by a number of surgery characteristics. The rational use of analgesics should be considered in combination with surgery type, surgery level, surgery duration and anesthesia method.
