Incidence of persistent opioid use following traumatic injury

Opioid Administration in the Trauma Bay for Minor Injuries Does Not Improve Disposition

OBJECTIVES

Opioid usage in the trauma bay is a common practice for pain management. We evaluated the administration of opioids to patients with minimal injury to determine disposition and factors for opioid administration.

METHODS

A retrospective study at a single institution was conducted utilizing records of trauma activations with an ISS of 3 or less between 1/1/2022 and 10/29/2022. Patients who are incarcerated, pregnant, or received an opioid prior to arrival were excluded. Categorical variables were analyzed using chi-square tests, and continuous variables were analyzed using t-tests.

RESULTS

557 patients met inclusion criteria. One in five patients were administered an opioid (22%). The majority of patients who received opioids were between the ages of 25 and 44 (OR 1.218 [.693, 2.141]), black (OR 3.077 [2.066, 4.584]), and had Medicaid insurance (OR 1.390 [.883, 2.187]). Patients who received an opioid reported a higher pain level (8 [6, 9] v 5 [2, 8], P = .0001), despite no difference in ISS. No significant difference was found in patient dispositions (P = .1759). When fentanyl was administered, doses greater than 50 mcg were administered to highest activation level trauma patients (40% v 10% P = .0001).

CONCLUSION

Opioid administration for patients with minor injuries does not improve patient disposition. The majority of patients with minor injuries being treated with opioids are young, black, and Medicaid patients. This research suggests consideration for establishing a non-opioid analgesic medication as first-line pain management for patients without evidence of significant injury on initial evaluation.

Education of trauma patients on opioids and pain management: A quality improvement project

BACKGROUND

Our acute care surgery team sustainably launched a pain management quality improvement project to reduce opioid prescriptions without affecting pain control in our elective surgery patients that was adopted on the inpatient acute care surgery service. Consequently, we implemented patient education on opioids and pain management aiming at decreasing opioid use without compromising pain management for acutely injured patients on the trauma service.

METHODS

Trauma patients admitted from August 1, 2021, to July 31, 2022, and discharged to home were included. Pain management education started on February 2022. Demographics, injury severity scores (ISSs), preadmission opioid and adjunct use, and type/dose of opioids and nonopioid adjuncts prescribed 24 hours predischarge and at discharge were collected. Opioids were converted to oral morphine milligram equivalents (MME). Phone calls for pain and opioid prescription refills were collected. The pre- and posteducation groups were compared using univariate analysis. Multivariate analyses were conducted to identify factors associated with phone calls for pain and opioid refills.

RESULTS

Three hundred sixty-eight patients were included, 200 pre- and 168 posteducation. MME prescribed at discharge was positively associated with 24-hour predischarge MME (B = 0.010 [0.007-0.012], P < .001) and negatively associated with preinjury opioid use (B = -0.405 [-0.80 to -0.008], P = .045). Patient education led to an increased number of adjuncts prescribed (P < .008), decreased phone calls for pain (OR = 0.356 [0.165-0.770], P = .009), and decreased opioid refills (OR = 0.297 [0.131-0.675], P = .004), but no change in opioid prescriptions.

CONCLUSION

Patient education on opioids and pain management led to decreased phone calls for inadequate pain management and decreased number of opioid refills.

Ketamine for acute pain after trauma: A pragmatic, randomized clinical trial

BACKGROUND

Non-narcotic intravenous medications may be a beneficial adjunct to oral multimodal pain regimens (MMPRs) which reduce but do not eliminate opioid exposure and prescribing after trauma. We hypothesized that the addition of a subdissociative ketamine infusion (KI) to a standardized oral MMPR reduces inpatient opioid exposure.

METHODS

Eligible adult trauma patients admitted to the intermediate or intensive care unit were randomized upon admission to our institutional MMPR per usual care (UC) or UC plus subdissociative KI for 24 hours to 72 hours after arrival. The primary outcome was morphine milligram equivalents per day (MME/d) and secondary outcomes included total MME, discharge with an opioid prescription (OP%), and rates of ketamine side effects. Bayesian posterior probabilities (pp) were calculated using neutral priors.

RESULTS

A total of 300 patients were included in the final analysis with 144 randomized to KI and 156 to UC. Baseline characteristics were similar between groups. The Injury Severity Scores for KI were 19 [14, 29] versus UC 22 [14, 29]. The KI group had a lower rate of long-bone fracture (37% vs. 49%) and laparotomy (16% vs. 24%). Patients receiving KI had an absolute reduction of 7 MME/day, 96 total MME, and 5% in OP%. In addition, KI had a relative risk (RR) reduction of 19% in MME/day (RR, 0.81 [0.69-0.95], pp = 99%), 20% in total MME (RR, 0.80 [0.64-0.99], pp = 98%), and 8% in OP% (RR, 0.92 [0.76-1.11], pp = 81%). The KI group had a higher rate of delirium (11% vs. 6%); however, rates of other side effects such as arrythmias and unplanned intubations were similar between groups.

CONCLUSION

Addition of a subdissociative ketamine infusion to an oral MMPR resulted in a decrease in opioid exposure in severely injured patients. Subdissociative ketamine infusions can be used as a safe adjunct to decrease opioid exposure in monitored settings.

Peripheral Nerve Stimulation for Treating Acute Pain Following Traumatic Fracture: A Case Report of Rapid-Onset Analgesia Without Motor Blockade

Analgesia following acute traumatic fracture remains a clinical challenge. Pain relief via peripheral nerve stimulation (PNS) is a promising treatment modality due to its opioid-sparing effects and rapid, reversible sensory blockade without motor blockade. We present the case of a patient who suffered a traumatic tibial plateau fracture. A popliteal sciatic PNS device was placed on postoperative day 1 following inadequate pain control. The patient reported marked pain relief, a significant reduction in morphine milligram equivalent (MME) utilization, and improved early functional recovery. The PNS lead was removed at the patient's 2-month follow-up visit without any adverse events.

Latest Advances in Regional Anaesthesia

Training and expertise in regional anaesthesia have increased significantly in tandem with increased interest over the past two decades. This review outlines the most recent advances in regional anaesthesia and focuses on novel areas of interest including fascial plane blocks. Pharmacological advances in the form of the prolongation of drug duration with liposomal bupivacaine are considered. Neuromodulation in the context of regional anaesthesia is outlined as a potential future direction. The growing use of regional anaesthesia outside of the theatre environment and current thinking on managing the rebound plane after regional block regression are also discussed. Recent relevant evidence is summarised, unanswered questions are outlined, and priorities for ongoing investigation are suggested.

Perioperative Opioid-Related Harms: Opportunities to Minimize Risk

Although substantial attention has been given to opioid prescribing in the United States, opioid-related mortality continues to climb due to the rising incidence and prevalence of opioid use disorder. Perioperative care has an important role in the consideration of opioid prescribing and the care of individuals at risk for poor postoperative pain- and opioid-related outcomes. Opioids are effective for acute pain management and commonly prescribed for postoperative pain. However, failure to align prescribing with patient need can result in overprescribing and exacerbate the flow of unused opioids into communities. Conversely, underprescribing can result in the undertreatment of pain, complicating recovery and impairing well-being after surgery. Optimizing pain management can be particularly challenging for individuals who are previously exposed to opioids or have critical risk factors, including opioid use disorder. In this review, we will explore the role of perioperative care in the broader context of the opioid epidemic in the United States, and provide considerations for a multidisciplinary, comprehensive approach to perioperative pain management and optimal opioid stewardship.

The Impact of Non-opioid Analgesic Usage on Total Opioid Load During Traumatic Brain Injury Rehabilitation: A Retrospective Study

Background Patients staying in acute rehabilitation often use large amounts of opioids during their stay. There are a number of reasons for this increased opioid exposure, including but not limited to daily exercises with physical and occupational therapists, increased demand on a healing body, and use of previously atrophying musculature. Some physiatrists have noticed that patients who concurrently are prescribed medications such as Robaxin seem to require fewer opioids during their stay in acute rehabilitation. This study aimed to determine the association between non-opioid analgesic use and total opioid load, as measured using morphine milligram equivalents (MMEs), during inpatient rehabilitation for traumatic brain injury. Methodology A retrospective study of individuals with a diagnosis of traumatic brain injury admitted to an acute inpatient rehabilitation program was performed. Non-opioid medications that were reviewed in the study included acetaminophen, amitriptyline, baclofen, diclofenac, gabapentin, ibuprofen, lidocaine, methocarbamol, nortriptyline, and pregabalin. Five of the most-used non-opioid medications (acetaminophen, diclofenac, gabapentin, lidocaine, and methocarbamol) were statistically analyzed using regression and analysis of variance to evaluate for any significant variables. Results Results showed that the average daily dose of acetaminophen has a significant effect on the average daily MME and that the average daily dose of gabapentin and methocarbamol each have a significant effect on the change of daily MME usage from admission to discharge from acute rehab (ΔMME). Results also showed that the mere presence of methocarbamol (regardless of daily or total dosage) had a significant effect on the ΔMME. Conclusions Based on these findings, physicians may want to consider prescribing acetaminophen, gabapentin, or methocarbamol for patients admitted for inpatient rehabilitation following traumatic brain injury who require high amounts of opioids.
