An Evidence-Based Approach to the Prescription Opioid Epidemic in Orthopedic Surgery

Ballistic trauma patients have decreased early narcotic demand relative to blunt trauma patients: Blunt ballistic injury opioid use

OBJECTIVES

Blunt and ballistic injuries are two common injury mechanisms encountered by orthopaedic traumatologists. However the intrinsic nature of these injures may necessitate differences in operative and post-operative care. Given the evolving opioid crisis in the medical community, considerable attention has been given to appropriate management of pain; particularly in orthopaedic patients. We sought to evaluate relative postoperative narcotic use in blunt injuries and ballistic injuries.

DESIGN

Retrospective Cohort Study.

SETTING

Academic Level-1 Trauma Center.

PATIENTS

96 Patients with blunt or ballistic fractures.

INTERVENTION

Inpatient narcotic pain management after orthopaedic fracture management.

MAIN OUTCOME MEASUREMENTS

Morphine equivalent units (MEU).

RESULTS

Patients with blunt injuries had a higher MEU compared to ballistic injuries in the first 24 hours postoperatively (35.0 vs 29.5 MEU, p=0.02). There were no differences in opiate consumption 24-48 hours (34.8 vs 28.0 MEU), 48 hours - 7 days post op (28.4 vs 30.4 MEU) or the 24 hours before discharge (30.0 vs 28.6 MEU). On multivariate analysis, during the 24-48 hours and 24 hours before discharge timepoints total EBL was associated with increased opioid usage. During days 3-7 (p<0.001) and in the final 24 hours prior to discharge (p=0.012), the number of orthopaedic procedures was a predictor of opioid consumption.

CONCLUSION

Blunt injuries required an increased postoperative narcotic consumption during the first 24 hours of inpatient stay following orthopedic fracture fixation. However, there was no difference at other time points. Immediate post-operative pain regimens may be decreased for patients with ballistic injuries.

Enhanced recovery pathway in adult patients undergoing thoracolumbar deformity surgery

BACKGROUND CONTEXT

Enhanced recovery (ERAS) pathways can help hospitals maximize the incentives of bundled payment models while maintaining high-quality patient care. A key component of an enhanced recovery pathway is the ability to predictably reduce inpatient length of stay, as this is a critical component of the cost equation.

PURPOSE

To determine the efficacy of an enhanced recovery pathway on reducing length of stay after thoracolumbar adult deformity surgery.

STUDY DESIGN

Single surgeon retrospective review of prospectively-collected data.

PATIENT SAMPLE

Forty adult deformity patients who underwent ≥5 levels of fusion to the pelvis (two to L5) with a single surgeon before and after implementation of an ERAS pathway.

METHODS

The pathway involved participation by anesthesiology, hospital medicine, and physical therapy, and was designed to achieve goals previously associated with decreased LOS (eg, EBL<1200 mL, procedure time <4.5 hours, avoidance of ICU postoperatively, and mobilization POD0-1). Patients were propensity-score matched 1:1 to a historical cohort (enhanced recovery [ER] and historical [H] cohorts), based on demographics, medical comorbidities, radiographic alignment parameters, and surgical factors. Outcomes were compared to determine the effect of the enhanced recovery pathway. Primary outcomes included LOS and 90-day complications and readmissions.

RESULTS

After matching, gender, BMI, ASA class, preoperative opioid dependence, day of surgery, sagittal alignment parameters, rate of revision surgery, three-column osteotomies, and interbody fusions were comparable between the cohorts (p>.05). In the ER cohort, there was reduced EBL (920±640 vs. 1437±555, p=.004) and no ER patient went to the ICU immediately following surgery, compared with 30% of H patients (p=.022). The ER cohort also had a greater number of patients ambulating by POD1 compared to the H cohort (100% vs. 55%, p=.010). ER patients had a shorter LOS (4.5±1.3 vs. 7.3±4.4 days, p=.010). A 90-day readmission and complications were comparable between the cohorts (p>.05).

CONCLUSIONS

The creation of an ERAS pathway for patients undergoing thoracolumbar adult deformity surgery reduced length of stay without negatively affecting short-term morbidity and complications. Given the specificity of this pathway to a single surgeon and hospital, the resources and staffing changes that were instrumental in creating the pathway may not be generalizable to other centers.

An international multidisciplinary consensus statement on the prevention of opioid-related harm in adult surgical patients

This international multidisciplinary consensus statement was developed to provide balanced guidance on the safe peri-operative use of opioids in adults. An international panel of healthcare professionals evaluated the literature relating to postoperative opioid-related harm, including persistent postoperative opioid use; opioid-induced ventilatory impairment; non-medical opioid use; opioid diversion and dependence; and driving under the influence of prescription opioids. Recommended strategies to reduce harm include pre-operative assessment of the risk of persistent postoperative opioid use; use of an assessment of patient function rather than unidimensional pain scores alone to guide adequacy of analgesia; avoidance of long-acting (modified-release and transdermal patches) opioid formulations and combination analgesics; limiting the number of tablets prescribed at discharge; providing deprescribing advice; avoidance of automatic prescription refills; safe disposal of unused medicines; reducing the risk of opioid diversion; and better education of healthcare professionals, patients and carers. This consensus statement provides a framework for better prescribing practices that could help reduce the risk of postoperative opioid-related harm in adults.

Notable Variability in Opioid-prescribing Practices After Common Orthopaedic Procedures

INTRODUCTION

The purpose of this study was to evaluate nationwide trends and regional variability in opioid prescriptions after common orthopaedic procedures.

METHODS

A retrospective analysis of privately insured subjects from the MarketScan database between 2015 and 2016 was conducted. Median oral morphine equivalents and interquartile ranges were analyzed by region for the initial post-op prescriptions and 90-day total prescriptions for opioid-naive patients undergoing the following: carpal tunnel release; anterior cruciate ligament reconstruction; arthroscopic meniscectomy; bimalleolar ankle fracture open reduction and internal fixation; distal radius fracture open reduction and internal fixation; arthroscopic rotator cuff repair; single-level anterior cervical discectomy and fusion; and total shoulder, hip, and knee arthroplasties. We hypothesized that notable regional variability exists with postoperative narcotic prescribing habits.

RESULTS

Seventy three thousand nine hundred twenty-one opioid-naive patients were identified. A notable regional variability was observed across the United States in the prescriptions given for all procedures, except total joint arthroplasty. Furthermore, although patients undergoing soft-tissue-only procedures required the fewest refills, patients undergoing total joint arthroplasty required the most.

DISCUSSION

Notable regional variability exisits in opioid prescribing patterns for many common orthopaedic procedures. Furthermore, prescriptions were smallest in the region most affected by the opioid epidemic. This information can be used to re-evaluate recommendations, serve as a benchmark for surgeons, and develop institutional and quality improvement guidelines to reduce excess postoperative opioid prescriptions.

Retrospective chart review of perioperative pain management of patients having surgery for closed ankle fractures using peripheral nerve blocks at a level one trauma center

Chronic opioid use is unfortunately perceived among these postoperative patients, specifically within orthopedic surgery. Patients having orthopedic surgeries are at risk for becoming addicted to opioids, and one benefit of peripheral nerves blocks could be to provide an alternative mode of pain control. This study takes a retrospective look at the use of peripheral nerve blocks for pain control following surgery for isolated traumatic ankle injuries. We hypothesize that when peripheral nerve blocks are administered preoperatively to patients with closed ankle fractures, they will have overall better control of postoperative pain compared to patients who did not receive a peripheral nerve block.

OBJECTIVES

The objective of this investigation was to evaluate the effect of preoperative peripheral nerve blockade on pain outcomes after ankle fracture surgery.

METHODS

After approval from our institutional review board, a Current Procedural Terminology code search was performed of all patients within our institution over a 3-year data collection period (August 2016-June 2019). This resulted in 177 subjects who underwent isolated closed ankle fracture open reduction internal fixation (ORIF), of which 71 subjects met inclusion criteria.

RESULTS

Results of the primary outcome measures found no difference in the mean postoperative care unit (PACU) pain scores between the groups (2.39 ± 2.91 vs 3.52 ± 3.09; P = 0.1724) nor the frequency of those who reported only mild pain (63.0% vs 47.10%; P = 0.2704). Subjects who received a peripheral nerve block spent more time in the PACU before discharge (2.06 ± 1.05 vs 0.94 ± 1.21 hours; P = 0.0004). Subjects receiving a peripheral nerve block were more likely to be given no analgesics in the PACU (38.9% vs 11.8%; P = 0.042) and less likely to receive a narcotic analgesic in the PACU (53.7% vs 82.4%; P = 0.047).

CONCLUSION

Although the results of this investigation demonstrate no significant difference in the mean PACU pain scores, they do demonstrate a significant difference in the amount of pain medication given in the PACU setting. This information will be used for future investigations of this discrepancy between pain perception and need for immediate postoperative pain medications as it relates to multimodal pain control in the setting of ankle fracture surgery.

"Pill Pushers and CBD Oil"-A Thematic Analysis of Social Media Interactions About Pain After Traumatic Brachial Plexus Injury

Purpose

Brachial plexus injury (BPI) patients use on-line groups for peer support, often seeking information from Facebook groups devoted to BPI. We hypothesized that a qualitative thematic analysis of posts from BPI Facebook groups would demonstrate the areas in which patients were seeking information regarding treatment of BPI and reveal potential sources of misinformation that patients may encounter.

Methods

We identified the 2 most popular public Facebook groups for BPI by searching key words “traumatic brachial plexus injury.” We selected posts containing comments regarding BPI from November 1, 2018 through October 31, 2019. We excluded posts regarding brachial plexus birth injury. We used iterative inductive and deductive thematic analysis for the qualitative data to identify recurring topics, knowledge gaps, potential roles of patient educational interventions, and patient interaction dynamics. Two investigators independently coded all posts and resolved discrepancies by discussion.

Results

A total of 7,694 posts from 2 leading Facebook support groups were analyzed. Three themes emerged: (1) When discussing pain management, there was recurring anti-opioid sentiment. Posters who currently used opioids or supported those who did discussed perceived effects of the opioid epidemic on their treatment, on their relationships with care providers, and on availability of the medication. (2) Posters advocated for alternatives to traditional approaches to pain management, referring to prescribers as pill pushers and touting cannabinoids as a safer and more effective replacement. (3) There was strong anti-gabapentinoid sentiment owing to reported adverse effects and a perceived lack of efficacy, despite its role as a first-line treatment for neuropathic pain.

Conclusions

Examination of posts from Facebook support groups for BPI revealed recurring themes, questions, misinformation, and opinions from posters with regard to treatment of neuropathic pain. These findings can help clinicians who care for BPI patients identify areas to focus on during patient encounters to address neuropathic pain that commonly occurs with BPI.

Clinical relevance

Brachial plexus injury surgeons should be aware of information, misinformation, and opinions on social media, because these may influence patient–surgeon interactions.

Outcomes of Preoperative Opioid Usage in Hip Arthroscopy: A Comparison With Opioid-Naïve Patients

PURPOSE

To compare postoperative outcomes between opioid-naïve patients and patients with a history of preoperative opioid usage undergoing hip arthroscopy. The secondary purpose is to determine whether preoperative opioid users consumed more oral morphine milligram equivalents than opioid-naïve patients following surgery.

METHODS

This is a single-center, retrospective analysis comparing outcomes and postoperative opioid usage between patients with and without a history of preoperative opioid use. Inclusion criteria included patients ≥18 years, Tönnis grade 0 or 1, imaging consistent with FAI or labral pathology, and a diagnosis of symptomatic FAI requiring hip arthroscopy. Patient outcomes were compared throughout a 2-year follow-up using the modified Harris Hip Score, Nonarthritic Hip Score, and visual analog scale (VAS).

RESULTS

In total, 17 patients were evaluated in each cohort. The mean age of the study cohort and control cohort were 52.0 ± 9.4 years and 51.2 ± 12.2 years, respectively. Female patients were 58.8% (n = 10) of both cohorts. Non-naïve patients had a lower preoperative Nonarthritic Hip Score (P = .05) and a greater VAS at their 6-month and 1-year (P < .001) postoperative visits. Naïve patients reported greater modified Harris Hip Scores 2 years postoperatively (P < .001). The study cohort was prescribed greater levels of oral morphine equivalents at the postoperative 1-year visit (P = .05). Opioid-naïve patients were more likely to reach minimally clinically important difference and patient acceptable symptom state of VAS at a faster rate. At the 2-year follow-up, 11.8% of opioid-naïve patients continued to take opioids compared with 58.8% from the non-naïve group for persistent hip pain (P < .001).

CONCLUSIONS

We determined that preoperative opioid usage in patients undergoing hip arthroscopy is associated with inferior outcomes compared with opioid-naïve patients. In addition, preoperative opioid users are likely to continue the use of opioid medications postoperatively and at greater doses than opioid-naïve patients.

Perioperative Opioid Use Predicts Postoperative Opioid Use and Inferior Outcomes After Shoulder Arthroscopy

PURPOSE

The purpose of this study is to define the impact of preoperative opioid use on postoperative opioid use, patient-reported outcomes, and revision rates in a cohort of patients receiving arthroscopic shoulder surgery.

METHODS

Patients who underwent shoulder arthroscopy were identified from an institutional database. Inclusion criteria were completion of preoperative and postoperative patient-reported outcome measures (PROMs) at 1-year follow-up and completion of a questionnaire on use of opioids and number of pills per day. Outcomes assessed included postoperative PROM scores, postoperative opioid use, persistent pain, and achievement of the patient acceptable symptomatic state. A matched cohort analysis was performed to evaluate the impact of opioid use on achievement of postoperative outcomes, whereas a multivariate regression was performed to determine additional risk factors. Receiver operating characteristic curves were used to establish threshold values in oral morphine equivalents (OMEs) that predicted each outcome.

RESULTS

A total of 184 (16.3%) patients were included in the opioid use (OU) group and 1,058 in the no opioid use (NOU) group. The OU and NOU groups showed statistically significant differences in both preoperative and postoperative scores across all PROMs (P < .001). Multivariate logistic regression identified preoperative opioid use as a significant predictor of reduced achievement of the patient acceptable symptomatic state (odds ratio [OR], 0.69, 95% confidence interval [CI], 0.29-0.83, P = .008), increased likelihood of endorsing persistent pain (OR, 1.73, 95% CI, 1.17-2.56, P = .006), and increased opioid use at 1 year (OR, 21.3, 95% CI, 12.2-37.2, P < .001). Consuming a high dosage during the perioperative period increased risk of revision surgery (OR, 8.59, 95% CI, 2.12-34.78, P < .003). Results were confirmed by matched cohort analysis. Receiver operating characteristic analysis found that total OME >1430 mg/d in the perioperative period (area under the curve, 0.76) and perioperative daily OME >32.5 predicted postoperative opioid consumption (area under the curve, 0.79).

CONCLUSIONS

Patients with a history of preoperative opioid use can achieve significant improvements in patient-reported outcomes after arthroscopic shoulder surgery. However, preoperative opioid use negatively impacts patients' level of satisfaction and is a significant predictor of pain and continued opioid usage.

The Impact of Arthroplasty Fellowship Training on Total Joint Arthroplasty: Comparison of Peri-Operative Metrics between Fellowship-Trained Surgeons and Non-Fellowship-Trained Surgeons

BACKGROUND

We sought to identify differences between total joint arthroplasties (TJAs) performed by adult reconstruction fellowship-trained surgeons (FT) than non-fellowship-trained surgeons (NFT).

METHODS

A single-institution database was utilized to identify patients who underwent elective TJA between 2016 and 2019.

RESULTS

In total, 16,882 TJAs were identified: 9111 total hip arthroplasties (THAs) and 7771 total knee arthroplasties (TKAs). Patients undergoing THA by FT surgeons were older (63.11 vs 61.84 years, P < .001), more likely to be white, insured by Medicare, and less likely to be active smokers (P < .0001). Both surgical time (90.03 vs 113.1 minutes, P < .0001) and mean length of stay (LOS) (1.85 vs 2.72 days, P < .0001) were significantly shorter for THAs performed by FT surgeons than NFT surgeons. A significantly greater percentage of patients were discharged home after THA by FT surgeons than NFT surgeons (88.7% vs 85.2%, P = .002). FT patients were quicker to mobilize with therapy and required 25% less opioids. TKAs performed by FT surgeons were associated with shorter surgical times (87.4 vs 94.92 minutes, P < .0001), LOS (2.62 vs 2.84 days, P < .0001), and nearly 19% less opioid requirement in the peri-operative period. In addition to higher Activity Measure for Post-Acute Care scores associated with FT surgeons after TKA, a significantly greater percentage of patients were discharged home after TKA by FT surgeons than NFT surgeons (83.97% vs 80.16%, P < .001).

CONCLUSION

For both THA and TKA, patients had significantly shorter surgical times, LOS, and required less opioids when their procedure was performed by FT surgeons compared to NTF surgeons. Patients who had their TJA performed by a FT surgeon achieved higher Activity Measure for Post-Acute Care scores and were discharged home more often than NFT surgeons. In an era of value-based care, more attention should be paid to the patient outcomes and financial implications associated with arthroplasty fellowship training.

Risk Factors for Increased Postoperative Pain and Recommended Orderset for Postoperative Analgesic Usage

An interdisciplinary pain team was established at our institution to explore options for improving pain control in patients undergoing orthopedic surgery by identifying traits that put a patient at increased risk for inadequate pain control postoperatively.

Differences in Pain, Opioid Use, and Function Following Unicompartmental Knee Arthroplasty compared to Total Knee Arthroplasty

BACKGROUND

We sought to determine if immediate postsurgical pain, opioid use, and clinical function differed between unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA).

METHODS

A single-institution database was utilized to identify patients who underwent elective total joint arthroplasty between 2016 and 2019.

RESULTS

In total, 6616 patients were identified: 98.20% TKA (6497) and 1.80% (119) UKA. UKA patients were younger, had lower body mass index, and more often male than the TKA cohort. Aggregate opioid consumption (75.94 morphine milligram equivalents vs 136.5 morphine milligram equivalents; P < .001) along with the first 24-hour and 48-hour usage was significantly less for UKA as compared to TKA. Similarly, pain scores (1.98 vs 2.58; P < .001) were lower for UKA while Activity Measure for Post-Acute Care mobilization scores were higher (21.02 vs 18.76; P < .001). UKA patients were able to be discharged home on the day of surgery 37% of the time as compared to 2.45% of TKA patients (P < .0001). Notably, when comparing UKA and TKA patients who were discharged home on the day of surgery, no differences regarding pain scores, opioid utilization, or mobilization were observed.

CONCLUSION

UKA patients are younger, have lower body mass index and American Society of Anesthesiologists scores, and more often male than TKA patients. UKA patients had significantly shorter length of stay than TKA patients and were discharged home more often than TKA patients, on both the day of surgery and following hospital admission. Most notably, UKA patients reported lower pain scores and were found to require 45% lower opioid medication in the immediate postsurgical period than TKA patients. Surprisingly, UKA and TKA patients discharged on the day of surgery did not differ in terms of pain scores, opioid utilization, or mobilization, suggesting that our rapid rehabilitation UKA protocols can be successfully translated to outpatient TKAs with similar outcomes.

High-Risk Prescribing Increases Rates of New Persistent Opioid Use in Total Hip Arthroplasty Patients

BACKGROUND

The association between surgeon prescribing practices and new persistent postoperative opioid use is not well understood. We examined the association between surgeon prescribing and new persistent use among total hip arthroplasty (THA) patients.

METHODS

A retrospective analysis of Medicare claims in Michigan was performed. The study cohort consisted of orthopedic surgeons performing THAs from 2013 to 2016 and their opioid-naïve patients, aged >65 years. High-risk prescribing included high daily doses, overlapping benzodiazepine prescriptions, concurrent opioid prescriptions, prescriptions from multiple providers, or long-acting opioid prescriptions. The occurrence of a preoperative prescription, initial prescription size, and 30-day prescription dosage were examined as individual exposures. Surgeons were categorized into quartiles by prescribing practices, and multilevel hierarchical logistic regression was used to examine associations with postoperative new persistent opioid use.

RESULTS

Surgeons exhibited high-risk prescribing for 66% of encounters. Patients of surgeons with the highest rates of high-risk prescribing were more likely to develop persistent use compared with patients of surgeons with the lowest rates (adjusted rates: 9.7% vs 4.6%, P = .011). Patients of surgeons with initial prescription sizes in the "high" (third) quartile (adjusted odds ratio, 2.91; 95% confidence interval, 1.53-5.51), and of surgeons in the "highest" (fourth) quartile of 30-day prescription dosage (adjusted odds ratio, 1.93; 95% confidence interval, 1.03-3.61), were more likely to develop persistent opioid use compared with patients of surgeons with low initial and 30-day prescription sizes, respectively.

CONCLUSION

The development of persistent opioid use after surgery is multifactorial, and surgeon prescribing patterns play an important role. Reducing prescribing and encouraging opioid alternatives could minimize postoperative persistent opioid use.

Postoperative Pain Management of Non-"Opioid-Naive" Patients Undergoing Hand and Upper-Extremity Surgery

Background: Patients with prior opioid use are often difficult to manage postoperatively. We examined potential strategies for managing these patients: (1) prescribing a different opioid; and (2) encouraging the use of nonopioid analgesics over opioids. Methods: A pain control program was implemented at an outpatient hand and upper-extremity center. Patients were recruited before (n = 305) and after (n = 225) implementation. Seventy of them were taking opioids prior to surgery. Information about pain control satisfaction and opioid use was collected. The Fisher exact test was used to compare categorical variables with small expected frequencies. Wilcoxon rank sum test was used to compare nonnormally distributed continuous variables. Results: Opioid users used 28.8 ± 25.6 opioid pills; nonopioid users used 14.5 ± 21.5 pills. Furthermore, 41.4% of opioid users sought more pills after surgery compared with 14.0% among nonopioid users. The pain control program was more effective in reducing opioid consumption and waste and increasing nonopioid consumption for nonopioid users than for opioid users. Prior opioid users who were prescribed a different opioid after surgery used 24.6 ± 22.0 opioid pills. Patients prescribed the same opioid used 37.9 ± 30.8 pills. Conclusions: Patients taking opioids prior to hand and upper-extremity surgery use more opioid pills, seek more pills after surgery, and are less satisfied with their pain control than their nonopioid user counterparts. Furthermore, the comprehensive pain plan was less effective in this patient population. Prescribing a different opioid reduced medication requirements for these patients, but additional strategies are needed to address postoperative pain management.

Does Surgical Intensity Correlate With Opioid Prescribing?: Classifying Common Surgical Procedures

OBJECTIVE

To examine the relationship between aspects of surgical intensity and postoperative opioid prescribing.

SUMMARY OF BACKGROUND DATA

Despite the emergence of postoperative prescribing guidelines, recommendations are lacking for many procedures. Identifying a framework based on surgical intensity to guide prescribing for those procedures in which guidelines may not exist could inform postoperative prescribing.

METHODS

We used clustering analysis with 4 factors of surgical intensity (intrinsic cardiac risk, pain score, median operative time, and work relative value units) to devise a classification system for common surgical procedures. We used IBM MarketScan Research Database (2010-2017) to examine the correlation between this framework with initial opioid prescribing and rates of refill for each cluster of procedures.

RESULTS

We examined 2,407,210 patients who underwent 128 commonly performed surgeries. Cluster analysis revealed 5 ordinal clusters by intensity: low, mid-low, mid, mid-high, and high. We found that as the cluster-order increased, the median amount of opioid prescribed increased: 150 oral morphine equivalents (OME) for low-intensity, 225 OME for mid-intensity, and 300 OME for high-intensity surgeries. Rates of refill increased as surgical intensity also increased, from 17.4% for low, 26.4% for mid, and 48.9% for high-intensity procedures. The odds of refill also increased as cluster-order increased; relative to low-intensity procedures, high-intensity procedures were associated with 4.37 times greater odds of refill.

CONCLUSION

Surgical intensity is correlated with initial opioid prescribing and rates of refill. Aspects of surgical intensity could serve as a guide for procedures in which guidelines based on patient-reported outcomes are not available.

Pain and Opioid Use After Thoracic Surgery: Where We Are and Where We Need To Go

As many as one third of patients undergoing minimally invasive thoracic surgery and one half undergoing thoracotomy will have chronic pain, defined as pain lasting 2 to 3 months. There is limited information regarding predictors of chronic pain and even less is known about its impact on health-related quality of life, known as pain interference. Currently, there is a focus on decreased opioid prescribing after surgery. Interestingly, thoracic surgical patients are the least likely to be receiving opioids before surgery and have the highest rate of new persistent opioid use after surgery compared with other surgical cohorts. These studies of opioid use have identified important predictors of new persistent opioid use, but their findings are limited by failing to correlate opioid use with pain. The objectives of this invited review are to present the findings of pertinent studies of chronic pain and opioid use after thoracic surgery, "where we are," and to discuss gaps in our knowledge of these topics and opportunities for research to fill those gaps, "where we need to go."

Classifying Preoperative Opioid Use for Surgical Care

OBJECTIVE

We characterized patterns of preoperative opioid use in patients undergoing elective surgery to identify the relationship between preoperative use and subsequent opioid fill after surgery.

BACKGROUND

Preoperative opioid use is common, and varies by dose, recency, duration, and continuity of fills. To date, there is little evidence to guide postoperative prescribing need based on prior opioid use.

METHODS

We analyzed claims data from Clinformatics DataMart Database for patients aged 18 to 64 years undergoing major and minor surgery between 2008 and 2015. Preoperative use was defined as any opioid prescription filled in the year before surgery. We used cluster analysis to group patients by the dose, recency, duration, and continuity of use. Our primary outcome was second postoperative fill within 30 postoperative days. Our primary explanatory variable was opioid use group. We used logistic regression to examine likelihood of second fill by opioid use group.

RESULTS

Out of 267,252 patients, 102,748 (38%) filled an opioid prescription in the 12 months before surgery. Cluster analysis yielded 6 groups of preoperative opioid use, ranging from minimal (27.6%) to intermittent (7.7%) to chronic use (2.7%). Preoperative opioid use was the most influential predictor of second fill, with larger effect sizes than other factors even for patients with minimal or intermittent opioid use. Increasing preoperative use was associated with risk-adjusted likelihood of requiring a second opioid fill compared with naive patients [minimal use: odds ratio (OR) 1.49, 95% confidence interval (95% CI) 1.45-1.53; recent intermittent use: OR 6.51, 95% CI 6.16-6.88; high chronic use: OR 60.79, 95% CI 27.81-132.92, all P values <0.001).

CONCLUSION

Preoperative opioid use is common among patients who undergo elective surgery. Although the majority of patients infrequently fill opioids before surgery, even minimal use increases the probability of needing additional postoperative prescriptions in the 30 days after surgery when compared with opioid-naive patients. Going forward, identifying preoperative opioid use can inform surgeon prescribing and care coordination for pain management after surgery.

Opioid Use After Common Sports Medicine Procedures: A Systematic Review

CONTEXT

The prescription of opioids after elective surgical procedures has been a contributing factor to the current opioid epidemic in North America.

OBJECTIVE

To examine the opioid prescribing practices and rates of opioid consumption among patients undergoing common sports medicine procedures.

DATA SOURCES

A systematic review of the electronic databases EMBASE, MEDLINE, and PubMed was performed from database inception to December 2018.

STUDY SELECTION

Two investigators independently identified all studies reporting on postoperative opioid prescribing practices and consumption after arthroscopic shoulder, knee, or hip surgery. A total of 119 studies were reviewed, with 8 meeting eligibility criteria.

STUDY DESIGN

Systematic review.

LEVEL OF EVIDENCE

Level 4.

DATA EXTRACTION

The quantity of opioids prescribed and used were converted to milligram morphine equivalents (MMEs) for standardized reporting. The quality of each eligible study was evaluated using the Methodological Index for Non-Randomized Studies.

RESULTS

A total of 8 studies including 816 patients with a mean age of 43.8 years were eligible for inclusion. A mean of 610, 197, and 613 MMEs were prescribed to patients after arthroscopic procedures of the shoulder, knee, and hip, respectively. At final follow-up, 31%, 34%, and 64% of the prescribed opioids provided after shoulder, knee, and hip arthroscopy, respectively, still remained. The majority of patients (64%) were unaware of the appropriate disposal methods for surplus medication. Patients undergoing arthroscopic rotator cuff repair had the highest opioid consumption (471 MMEs), with 1 in 4 patients receiving a refill.

CONCLUSION

Opioids are being overprescribed for arthroscopic procedures of the shoulder, knee, and hip, with more than one-third of prescribed opioids remaining postoperatively. The majority of patients are unaware of the appropriate disposal techniques for surplus opioids. Appropriate risk stratification tools and evidence-based recommendations regarding pain management strategies after arthroscopic procedures are needed to help curb the growing opioid crisis.

Opioid Consumption After Arthroscopic Meniscal Procedures and Anterior Cruciate Ligament Reconstruction

Background:

Procedure-specific opioid-prescribing guidelines have the potential to decrease the number of unused pills in the home without compromising patient satisfaction. However, there is a paucity of data on the minimum necessary quantity to prescribe for outpatient orthopaedic surgeries.

Purpose:

To prospectively record daily opioid use and pain levels after arthroscopic meniscal procedures and anterior cruciate ligament reconstruction (ACLR) at a single institution.

Study Design:

Case series; Level of evidence, 4.

Methods:

A total of 95 adult patients who underwent primary arthroscopic knee surgery (meniscectomy, repair, or ACLR) were enrolled. Patients with a history of opioid dependence were ineligible. Daily opioid consumption and Numeric Rating Scale pain scores were collected through an automated text-messaging platform starting on postoperative day 1 (POD1). At 6 weeks or at patient-reported cessation of opioid use, final survey questions were asked. Patients who failed to complete data collection were excluded. Opioid use was converted into “pills” (oxycodone 5-mg equivalents) to facilitate comparisons and clinical applications. Factors associated with high and low opioid use were compared.

Results:

Of the 95 patients enrolled, 71 (74.7%) were included in the final analysis. Of these, 40 (56.3%) underwent meniscal surgery and 31 (43.7%) underwent ACLR. After outpatient arthroscopic meniscectomy or repair, the total median postdischarge opioid use was 0.3 pills (oxycodone 5-mg equivalents), with 75% of patients consuming 3.3 or fewer pills (range, 0-19 pills). For ACLR, the median postdischarge consumption was 7 pills (75th percentile, 23.3 pills; range, 0-41 pills). Almost one-third of patients (32.3%) took no opioids after surgery (3 ACLR, 20 meniscus). All meniscus patients and 71% of ACLR patients ceased opioid consumption by postoperative day 7.

Conclusion:

Opioids may not be necessary in all patients, particularly after meniscal surgery and in comparison with ACLR. For patients requesting opioids for pain relief, reasonable prescription quantities are 5 oxycodone 5-mg pills after arthroscopic meniscal procedures and 20 5-mg pills after ACLR. Slowing the current opioid epidemic and preventing future crises is dependent on refining prescribing habits. Clinicians should strongly consider patient education regarding expected pain as well as pain management strategies.

Proper Disposal of Prescription Opioids in Southwest Virginia: Assessment of Patient, Physician, and Medical Student Beliefs and Practices

CONTEXT

Southwestern Virginia demonstrates the highest regional mortality rate from prescription opioid overdoses. Nationally, 65% of patients misusing opioid medications received them from friends and family, underscoring the need for effective disposal of unused narcotics.

OBJECTIVES

(1) To understand patient, provider, and medical student beliefs and misconceptions regarding proper methods of opioid disposal; (2) to characterize discrepancies that exist between patient self-reported habits and medical student/provider perceptions of opioid usage, disposal, and diversion.

DESIGN

Descriptive, cross-sectional, observational study.

SETTING

Large, nonprofit health care organization and allopathic medical school in Southwestern Virginia.

PARTICIPANTS

All ambulatory patients 18 years or older presenting for elective consultation at health system orthopedics department; all institutionally employed physicians with active system e-mail addresses; and all current students at the associated medical school.

MAIN OUTCOMES/MEASURES

Patients: The number who had received information regarding proper methods of opioid disposal, intended disposal method, methods of disposal considered appropriate, comfort level with opioid disposal, and demographic data. Physicians and Medical Students: The number who had received instruction regarding proper methods of opioid disposal, acceptable means of opioid disposal, most appropriate disposal method, disposal method most likely to be employed by patients, practice profile/prescribing data, and medical school year.

RESULTS

In total, 64% of patients (n = 255/750) had never received instruction from a physician regarding opioid disposal; 56% of physicians (n = 212/732) and 78% (n = 80/171) of medical students indicated that they never received formal instruction regarding methods of disposal. The majority of physicians believed that their patients are most likely to use in-home methods of disposal or store prescription medications for future use; 61% of patients indicated a preference for accessible disposal facilities.

CONCLUSIONS

The discrepancy between patient and physician responses highlights a lack of communication regarding disposal of unused opioid medications and is a target for future intervention.

Standardized, Patient-specific, Postoperative Opioid Prescribing After Inpatient Orthopaedic Surgery

BACKGROUND

Opioid-related mortality has increased over the past 2 decades, leading to the recognition of a nationwide opioid epidemic and prompting physicians to reexamine their opioid prescribing practices. At our institutions, we had no protocol for prescribing opioids upon discharge after inpatient orthopaedic surgery, resulting in inconsistent and potentially excessive prescribing. Here, we report the results of the implementation of a patient-specific protocol using an opioid taper calculator to standardize opioid prescribing at discharge after inpatient orthopaedic surgery.

METHODS

The opioid taper calculator is a tool that creates a patient-specific opioid taper based on each patient's 24-hour predischarge opioid utilization. We implemented this taper for patients discharged after inpatient orthopaedic surgery at our two institutions (Boston Medical Center and Lahey Hospital and Medical Center-Burlington Campus). We compared discharge opioid quantities between orthopaedic patients postimplementation and quantities prescribed preimplementation. We also compared discharge opioid quantities between orthopaedic and nonorthopaedic surgical services over the same time period.

RESULTS

Nine-months postimplementation, a patient-specific taper was used in 74% of eligible discharges, resulting in a 24% reduction in opioids prescribed at discharge, along with a 35% reduction in variance. Over the same time frame, a smaller reduction (9%) was seen in the opioids prescribed at discharge by nonorthopaedic services. The most notable reductions were seen after total joint arthroplasty and spinal fusions. Despite this reduction, most patients (65%) reported receiving sufficient opioids, and no substantial change was observed in 30-day postdischarge opioid prescription refills after versus before protocol implementation (1.58 versus 1.71 fills per discharge).

DISCUSSION

Using the opioid taper calculator, a patient-specific taper can be successfully used to standardize opioid prescribing at discharge after inpatient orthopaedic surgery without a substantial risk of underprescription.

The Effect of the Strengthen Opioid Misuse Prevention Act on Opiate Prescription Practices Within the Orthopaedic Surgery Department of an Academic Medical Center

In 2017, the Department of Health and Human Service declared a public health emergency known as the opioid crisis. In North Carolina, the “Strengthen Opioid Misuse Prevention Act of 2017” (STOP Act) went into effect on January 1, 2018, seeking to strengthen oversight over opioid prescriptions. Among other mandates, this legislation limited the duration of the initial prescription to 5 or 7 days. The purpose of this study was to compare narcotic prescription practices within the Department of Orthopaedic Surgery at an academic medical center before and after the enactment of the STOP Act. We hypothesized that there would be a statistically significant decrease in the amount of postoperative opioids prescribed after the STOP Act and that this decrease would be consistent across all types of providers in the Orthopaedic Surgery Department.

Preoperative Patient Education May Decrease Postoperative Opioid Use After Meniscectomy

Purpose

To identify the current opioid prescribing and use practices after arthroscopic meniscectomy and to evaluate the role of preoperative patient education in decreasing postoperative opioid consumption.

Methods

Patients undergoing arthroscopic meniscectomy were prospectively identified for inclusion. They were placed into 1 of 2 groups: Group 1 received no education regarding opioid use after surgery, whereas group 2 received a standardized overview on postoperative opioid use. Patients were assigned to the groups consecutively: Patients treated at the beginning of the study were assigned to group 1, and patients treated at the end of the study were assigned to group 2. Data from group 1 were used to identify "normal" opioid prescribing and use practices and to guide patients in group 2 regarding normal postoperative opioid use. Patients were surveyed weekly for 4 weeks after surgery to determine the number of opioids taken. Postoperative opioid consumption was analyzed and compared between the 2 groups.

Results

A total of 62 patients completed the study (32 in group 1 and 30 in group 2). Patients in group 1 were prescribed an average of 42.0 opioid pills (95% confidence interval [CI], 34.0-51.0 pills) and used an average of 15.84 pills (95% CI, 9.26-22.4 pills) after surgery, whereas patients in group 2 used an average of 4.00 pills (95% CI, 2.12-5.88 pills) after surgery. Patients in group 2 used 11.84 fewer opioid pills (P = .001), a 296% decrease in postoperative opioid consumption. The number of patients who continued to take opioid pills 4 weeks after surgery was 7 patients (21.9%) in group 1 and 1 patient (3.3%) in group 2.

Conclusions

Preoperative patient education regarding opioids may decrease postoperative opioid consumption and the duration for which patients take opioid pills after arthroscopic meniscectomy.

Opioid Consumption Patterns After Lumbar Microdiscectomy or Decompression

STUDY DESIGN

Prospective observational study OBJECTIVE.: The aim of this study was to record daily opioid use and pain levels after 1-level lumbar decompression or microdiscectomy.

SUMMARY OF BACKGROUND DATA

The standardization of opioid-prescribing practices through guidelines can decrease the risk of misuse and lower the number of pills available for diversion in this high-risk patient population. However, there is a paucity of quantitative data on the "minimum necessary amount" of opioid appropriate for post-discharge prescriptions.

METHODS

At two institutions between September 2017 and 2018, we prospectively enrolled 85 consecutive adult patients who underwent one-level lumbar decompression or microdiscectomy. Patients with a history of opioid dependence were excluded. Daily opioid consumption and pain scores were collected using an automated text-messaging-based platform for 6 weeks or until consumption ceased. Refills during the study period were monitored. Patients were asked for the number of pills left over and the method of disposal. Opioid use was converted to oral morphine equivalents (OMEs). Results are also reported in terms of "pills" (oxycodone 5 mg equivalents) to facilitate clinical applications. Risk factors were compared between patients in the top and bottom half of opioid consumption.

RESULTS

Total opioid consumption ranged from 0 to 118 pills, with a median consumption of 32 pills (236.3 OME). Seventy-five percent of patients consumed ≤57 pills (431.3 OME). Mean Numeric Rating Scale pain scores declined steadily over the first 2 weeks. By postoperative day 7 half of the study population had ceased taking opioids altogether. Only 22.4% of patients finished their initial prescription, and only 9.4% of patients obtained a refill.

CONCLUSION

These data may be used to formulate evidence-based opioid prescription guidelines, establish benchmarks, and identify patients at the higher end of the opioid use spectrum.

A Multidisciplinary Patient-Specific Opioid Prescribing and Tapering Protocol Is Associated with a Decrease in Total Opioid Dose Prescribed for Six Weeks After Total Hip Arthroplasty

Objective

This retrospective cohort study tested the hypothesis that implementing a multidisciplinary patient-specific discharge protocol for prescribing and tapering opioids after total hip arthroplasty (THA) will decrease the morphine milligram equivalent (MME) dose of opioids prescribed.

Methods

With institutional review board approval, we analyzed a Perioperative Surgical Home database and prescription data for all primary THA patients three months before (PRE) and three months after (POST) implementation of this new discharge opioid protocol based on patients’ prior 24-hour inpatient opioid consumption. The primary outcome was total opioid dosage in MME prescribed and opioid refills for six weeks after surgery. Secondary outcomes included the number of tablets and MME prescribed at discharge, in-hospital opioid consumption, length of stay, and postoperative complications.

Results

Forty-nine cases (25 PRE and 24 POST) were included. Total median (10th–90th percentiles) MME for six weeks postoperatively was 900 (57–2082) MME PRE vs 295 (69–741) MME POST (mean difference = 721, 95% confidence interval [CI] = 127–1316, P = 0.007, Mann-Whitney U test). Refill rates did not differ. The median (10th–90th percentiles) initial discharge prescription in MME was 675 (57–1035) PRE vs 180 (18–534) POST (mean difference = 387, 95% CI = 156–618, P = 0.003, Mann-Whitney U test) MME. There were no differences in other outcomes.

Conclusions

Implementation of a patient-specific prescribing and tapering protocol decreases the mean six-week dosage of opioid prescribed by 63% after THA without increasing the refill rate.

Postoperative Opioid Consumption in Opioid-Naïve Patients Undergoing Hallux Valgus Correction

BACKGROUND

Postoperative pain management following orthopedic surgeries can be challenging, and the opioid epidemic has made it essential to better individualize opioid prescriptions by patient and procedure. The purpose of this subgroup analysis of a prospective study was to investigate immediate postoperative opioid pill consumption and prolonged use in patients undergoing operative correction of hallux valgus (HV).

METHODS

Patients undergoing outpatient HV correction procedures with 5 fellowship-trained foot and ankle surgeons over a 1-year period were included. Patients were excluded if they were being prescribed chronic opioid analgesics for an underlying condition prior to the date of initial injury or if they underwent concomitant nonforefoot procedures. At the patient's first postoperative visit, opioid pills were counted, and these were standardized to the equivalent number of 5-mg oxycodone pills. Linear regression analysis was performed to determine if any of the procedure categories or patient factors were independently associated with postoperative opioid consumption. Prolonged use of opioids 90 to 180 days after the procedure was also examined using our state's online Prescription Drug Monitoring Program (PDMP). One-hundred thirty-seven patients (86% female) were included. Thirty-six patients (26%) underwent primary chevron osteotomies, 78 (57%) underwent primary proximal osteotomies (Ludloff, scarf), 10 (7%) underwent soft tissue-only procedures with or without a first proximal phalanx osteotomy (modified McBride, Akin), and 13 (9%) underwent first metatarsophalangeal arthrodeses.

RESULTS

Overall, patients consumed a median of 27 pills. There was no significant difference in postoperative opioid intake between the 4 procedures, including when subdivided into those with and without lesser toe procedures. Higher preoperative visual analog scale pain levels (P = .028) and younger patient age (P = .042) were associated with higher opioid pill consumption. A total of 1.5% of patients demonstrated prolonged opioid use.

CONCLUSION

Our study demonstrated a lack of difference between HV procedures in terms of postoperative opioid consumption and an overall low rate of prolonged use in opioid-naïve patients.

Determinants of Pain and Predictors of Pain Relief after Ulnar Shortening Osteotomy for Ulnar Impaction Syndrome

Background  The purpose of this study is to characterize patient- and surgery-specific factors associated with perioperative pain level in patients undergoing ulnar shortening osteotomy (USO) for ulnar impaction syndrome (UIS). We hypothesize that preoperative opiate consumption, tobacco utilization, and severity of ulnar variance will be associated with less postoperative pain relief. Methods  All cases of USO between January 2010 and December 2016 for management of UIS were retrospectively reviewed. Patient demographics, smoking status, type of labor, and opioid utilization before surgery were recorded. Radiographic measurements for ulnar variance, radial tilt and inclination, as well as triangular fibrocartilage complex and distal radial-ulnar joint (DRUJ) morphology were assessed. Pre- and postoperative pain score were recorded. Regression analysis was performed to determine predictors of pain scores. Results  A total of 69 patients were included for the final analysis with a mean age of 44 years (range 17-73 years). Seventeen patients reported use of daily opioid medications at the time of surgery (25%). Patients who used opioid analgesics daily, active laborers, smokers, and patients involved in worker compensation claims had significantly less pain relief after surgery. Patients with osteotomy performed at the metaphysis had significantly more pain relief than patients that had diaphyseal osteotomy. Regression analysis identified tobacco utilization and anatomic site of osteotomy as independent predictors of postoperative pain. Conclusion  The results from this study identified smoking and location of osteotomy as independent predictors of postoperative pain relief. While smoking cessation is paramount to prevent delayed/nonunion it may also help improve pain relief following USO. The potential to achieve greater shortening with a metaphyseal osteotomy suggests that in addition to the mechanical unloading the carpus, pain relief after USO may also stem from tensioning the ulnar collateral ligaments of the wrist, the ECU subsheath, and the radioulnar ligaments. Level of Evidence  This is a Level III, therapeutic study.

Effect of the Strengthening Opioid Misuse Prevention (STOP) Act on Opioid Prescription Practices After Ankle Fracture Fixation

Background:

In North Carolina, the Strengthen Opioid Misuse Prevention Act of 2017 (STOP Act) went into effect on January 1, 2018, intending to increase oversight over opioid prescriptions. This study compares postoperative narcotic prescription practices following operative fixation of ankle fractures before and after the STOP Act.

Methods:

This study was a retrospective review of patients 18 years and older who underwent operative fixation of ankle fractures between January 1 and June 30, 2017 (before STOP Act), and between January 1 and June 30, 2018 (after STOP Act). Variables of interest included demographics, amount of opioids prescribed postoperatively, number of prescription refills, and number of pain-related calls or visits to the emergency department (ED) or clinic after surgery. This study assessed 71 patients in the Pre group and 47 patients in the Post group.

Results:

There was a statistically significant decrease in the average number of postoperative narcotic pills prescribed after the STOP Act (52.7 vs 76.2, P < .001). There was also a statistically significant decrease in the average number of prescription refills (0.6 vs 1.0, P = .037). There were no significant changes in pain-related clinic calls (35.2% Pre vs 34.0% Post, P = .896), pain-related clinic visits ahead of schedule (4.2% Pre vs 6.4% Post, P = .681), or pain-related ED visits (2.8% Pre vs 10.6% Post, P = .113).

Conclusion:

In the postoperative period after operative fixation of ankle fractures, the volume of narcotic prescriptions decreased after the new legislation, without an associated strain on medical resources.

Effects of Baseline Opioid Medication Use on Patient-Reported Functional and Psychological Impairment Among Hand Clinic Patients

PURPOSE

To test the null hypothesis that baseline opioid use is not associated with functional or psychological impairment among new hand surgery clinic patients, as measured by Patient-Reported Outcomes Measurement Information System (PROMIS) instruments.

METHODS

New adult (≥ 18 years) patient visits to a tertiary academic orthopedic nonshoulder hand and upper extremity clinic between February 2014 and April 2018 were eligible. Collected outcomes include the question, "Are you currently taking narcotic pain medications?", the PROMIS Upper Extremity (UE) computerized adaptive testing (CAT), abbreviated version of the Disorders of the Arm, Shoulder, and Hand (QuickDASH), PROMIS Physical Function (PF) CAT, PROMIS Pain Interference (PI) CAT, PROMIS Depression CAT, and PROMIS Anxiety CAT. Patients responding to the opioid question, plus the UE CAT or QuickDASH, were included. Bivariate and multivariable logistic regression modelling were used to assess factors associated with baseline scores.

RESULTS

Of 5997 included patients, 1,046 (17.4%) reported baseline opioid use. Patients in the opioid group demonstrated significantly worse scores on all patient-reported outcomes, and a significantly greater proportion of patients with PROMIS Depression CAT scores exceeding 60 (associated with a clinical diagnosis of depression; 29.5% vs 15.5%). Lower functional scores were observed in the opioid group after controlling for age, sex, other activity-limiting comorbidities, and either depression (UE CAT -7.0; QuickDASH +18.1; and PF CAT -6.6 points), anxiety (UE CAT -6.3; QuickDASH +16.4; PF CAT -6.3), or PI (UE CAT -3.7; QuickDASH +9.5; and PF CAT -4.2 points). Pain interference was greater among opiate users when controlling for age, sex, other activity-limiting comorbidities, and baseline function or psychological status: PI was 2.5, 5.0, or 4.3 points greater when controlling for the PROMIS UE CAT, Depression CAT, or Anxiety CAT.

CONCLUSIONS

New patients presenting to a hand surgery clinic who endorse use of opioid medications at baseline report significantly decreased physical function, increased psychological burden, and greater levels of pain interference than nonusers.

Optimizing opioid prescribing and pain treatment for surgery: Review and conceptual framework

Purpose

Millions of Americans who undergo surgical procedures receive opioid prescriptions as they return home. While some derive great benefit from these medicines, others experience adverse events, convert to chronic opioid use, or have unused medicines that serve as a reservoir for potential nonmedical use. Our aim was to investigate concepts and methods relevant to optimal opioid prescribing and pain treatment in the perioperative period.

Methods

We reviewed existing literature for trials on factors that influence opioid prescribing and optimization of pain treatment for surgical procedures and generated a conceptual framework to guide future quality, safety, and research efforts.

Results

Opioid prescribing and pain treatment after discharge from surgery broadly consist of 3 key interacting perspectives, including those of the patient, the perioperative team, and, serving in an essential role for all patients, the pharmacist. Systems-based factors, ranging from the organizational environment’s ability to provide multimodal analgesia and participation in enhanced recovery after surgery programs to other healthcare system and macro-level trends, shape these interactions and influence opioid-related safety outcomes.

Conclusions

The severity and persistence of the opioid crisis underscore the urgent need for interventions to improve postoperative prescription opioid use in the United States. Such interventions are likely to be most effective, with the fewest unintended consequences, if based on sound evidence and built on multidisciplinary efforts that include pharmacists, nurses, surgeons, anesthesiologists, and the patient. Future studies have the potential to identify the optimal amount to prescribe, improve patient-focused safety and quality outcomes, and help curb the oversupply of opioids that contributes to the most pressing public health crisis of our time.

Perioperative pain management and chronic postsurgical pain after elective foot and ankle surgery: a scoping review

PURPOSE

Chronic postsurgical pain (CPSP) can occur after elective mid/hindfoot and ankle surgery. Effective treatment approaches to prevent the development of CPSP in this population have not been extensively investigated. The impact of multimodal strategies to prevent CPSP following elective mid/hindfoot surgery is unknown because of both the heterogeneity of acute pain management and the lack of a recognized definition particular to this surgery. This review aimed to identify and evaluate current pain management strategies after elective mid/hindfoot and ankle surgery.

SOURCES

Manual and electronic searches (MEDLINE, Embase, and Cochrane Library) were conducted of literature published between 1990 and July 2017. Comparative studies of adults undergoing elective mid/hindfoot and ankle surgery were included. Two reviewers independently reviewed studies and assessed their methodological quality.

PRINCIPAL FINDINGS

We found seven randomized-controlled trials meeting our inclusion criteria. Interventions focused on regional anesthesia techniques such as continuous popliteal sciatic and femoral nerve blockade. Participants were typically followed up to 48 hr postoperatively. Only one study assessed pain six months following elective mid/hindfoot and ankle surgery.

CONCLUSION

There is an overwhelming lack of evidence regarding CPSP and its management for patients undergoing elective mid/hindfoot and ankle surgery. The lack of a recognized and standard definition of CPSP after this group of surgeries precludes accurate and consistent evaluation.

Frequency and Risk Factors for Prolonged Opioid Prescriptions After Surgery for Brachial Plexus Injury

PURPOSE

We hypothesized that patients with preoperative opioid prescriptions and diagnoses of depression and anxiety would be at increased risk for prolonged opioid prescriptions after surgery for brachial plexus injury (BPI).

METHODS

Using an administrative database of privately insured patients, we assembled a cohort of BPI surgery patients and a control group of non-BPI patients, matching for age, sex, and year. Pharmacy claims for prescriptions filled for opioids and neuropathic pain medications were examined 12 months before surgery to 180 days after surgery. The primary outcome was prolonged opioid prescription, defined as receiving a prescription 90 to 180 days after the index (BPI surgery or randomly selected date of service for controls). Multivariable regression was used to examine risk factors for postoperative opioid use, including diagnoses of depression, anxiety, drug abuse, tobacco use, and preoperative use of opioids and neuropathic pain medications. A subgroup analysis was performed for opioid-naive BPI patients between 30 days to 1 year before surgery.

RESULTS

Among BPI surgery patients (n = 1,936), 27.7% had prolonged opioid prescriptions. Among opioid-naive BPI patients (n = 911), 10.8% had prolonged opioid prescriptions. In controls (n = 19,360), frequency of prolonged opioid prescriptions was 0.11%. Among all BPI patients, after adjustment for age and sex, predictors of prolonged postoperative opioid prescriptions in BPI patients were preoperative opioids, preoperative neuropathic pain medication use, histories of drug abuse, tobacco use, and anxiety.

CONCLUSIONS

Prolonged postoperative opioids prescriptions after BPI reconstruction are higher than previous estimates among other surgical patients. In addition to establishing normative data among this population, our findings serve to increase awareness of risk factors for prolonged opioids after BPI reconstruction and encourage coordinated multidisciplinary care.

The prescription opioid crisis: role of the anaesthesiologist in reducing opioid use and misuse

Reports of strategies to prevent and treat the opioid epidemic are growing. Significant attention has been paid to the benefits of opioid addiction research, clinical prescribing, and public policy initiatives in curbing the epidemic. However, the role of the anaesthesiologist in minimising opioid use and misuse remains underexplored. For many patients with an opioid use disorder, the perioperative period represents the source of initial exposure. As perioperative physicians, anaesthesiologists are in the unique position to manage pain effectively while simultaneously decreasing opioid consumption. Multiple opportunities exist for anaesthesiologists to minimise opioid exposure and prevent subsequent persistent opioid use. We present a global strategy for decreasing perioperative opioid use and misuse among surgical patients. A historical perspective of the opioid epidemic is presented, together with an analysis of opioid supply and demand forces. We then present specific temporal strategies for opioid use reduction in the perioperative period. We emphasise the importance of preoperative identification of patients at risk for long-term opioid use and misuse, review the evidence supporting the opioid sparing capacity of individual multimodal analgesic agents, and discuss the benefits of regional anaesthesia for minimising opioid consumption. We describe postoperative and post-discharge tools, including effective multimodal analgesia and the role of a transitional pain service. Finally, we offer general institutional strategies that can be led by anaesthesiologists, identify gaps in knowledge, and offer directions for future research.

Design and Implementation of an Enhanced Recovery After Surgery (ERAS) Program for Minimally Invasive Lumbar Decompression Spine Surgery: Initial Experience

STUDY DESIGN

A retrospective cohort study of prospectively collected data.

OBJECTIVE

The aim of this study was to describe the development of and early experience with an evidence-based enhanced recovery after surgery (ERAS) pathway for lumbar decompression.

SUMMARY OF BACKGROUND DATA

ERAS protocols have been consistently associated with improved patient experience and outcomes, and reduced cost and length of hospital stay (LoS). Despite successes in other orthopedic subspecialties, ERAS has yet to be established in spine surgery. Here, we report the development of and initial experience with the first comprehensive ERAS pathway for MIS lumbar spine surgery.

METHODS

An evidence-based review of the literature was performed to select components of the ERAS pathway. The pathway was applied to 61 consecutive patients presenting for microdiscectomy or lumbar laminotomy/laminectomy between dates. Data collection was performed by review of the electronic medical record. We evaluated compliance with individual ERAS process measures, and adherence to the overall pathway. The primary outcome was LoS. Demographics, comorbidities, perioperative course, prevalence of opioid tolerance, and factors affecting LoS were also documented.

RESULTS

The protocol included 15 standard ERAS elements. Overall pathway compliance was 85.03%. Median LoS was 279 minutes [interquartile range (IQR) 195-398 minutes] overall, 298 minutes (IQR 192-811) for lumbar decompression and 285 minutes (IQR 200-372) for microdiscectomy. There was no correlation between surgical subtype or duration and LoS. Overall, 37% of the cohort was opioid-tolerant at the time of surgery. There was no significant effect of baseline opioid use on LoS, or on the total amount of intraoperative or PACU opioid administration. There were four complications (6.5%) resulting in extended LoS (>23 hours).

CONCLUSION

This report comprises the first description of a comprehensive, evidence-based ERAS for spine pathway, tailored for lumbar decompression/microdiscectomy resulting in short LoS, minimal complications, and no readmissions within 90 days of surgery.

Multimodal Pain Management for Major Joint Replacement Surgery

Effective pain management for orthopaedic major joint replacement is key to achieving earlier recovery, better functioning, and high rates of patient satisfaction. In an effort to decrease opioid dependency, practitioners are turning to multimodal pain management, which involves the use of multiple analgesic agents and techniques. To utilize this technique, a patient's history of and preoperative consumption of medications to treat pain impacts the success of this regimen. Multimodal pain management involves the use of nonsteroidal anti-inflammatory drugs, acetaminophen, N-methyl-D-aspartate antagonists, gabapentin, serotonin inhibitors, regional techniques, and opioids as needed. It is necessary for the nurse to understand the mechanism of pain and how the multimodal adjuncts target the pain response to benefit the patient's perioperative course as well as his or her postoperative and discharge management.

Opioid-free anesthesia within an enhanced recovery after surgery pathway for minimally invasive lumbar spine surgery: a retrospective matched cohort study

OBJECTIVE

Enhanced recovery after surgery (ERAS) and multimodal analgesia are established care models that minimize perioperative opioid consumption and promote positive outcomes after spine surgery. Opioid-free anesthesia (OFA) is an emerging technique that may achieve similar goals. The purpose of this study was to evaluate an OFA regimen within an ERAS pathway for lumbar decompressive surgery and to compare perioperative opioid requirements in a matched cohort of patients managed with traditional opioid-containing anesthesia (OCA).

METHODS

The authors performed a retrospective analysis of prospectively collected data. They included 36 patients who underwent lumbar decompression under their ERAS pathway for spinal decompression between February and August 2018. Eighteen patients who received OFA were matched in a 1:1 ratio to a cohort managed with a traditional OCA regimen. The primary outcome was total perioperative opioid consumption. Postoperative pain scores (measured using the numerical rating scale [NRS]), opioid consumption (total morphine equivalents), and length of stay (time to readiness for discharge) were compared in the postanesthesia care unit (PACU). The authors also assessed compliance with ERAS process measures and compared compliance during 3 phases of care: pre-, intra-, and postoperative.

RESULTS

There was a significant reduction in total perioperative opioid consumption in patients who received OFA (2.43 ± 0.86 oral morphine equivalents [OMEs]; mean ± SEM), compared to patients who received OCA (38.125 ± 6.11 OMEs). There were no significant differences in worst postoperative pain scores (NRS scores 2.55 ± 0.70 vs 2.58 ± 0.73) or opioid consumption (5.28 ± 1.7 vs 4.86 ± 1.5 OMEs) in the PACU between OFA and OCA groups, respectively. There was a clinically significant decrease in time to readiness for discharge from the PACU associated with OFA (37 minutes), although this was not statistically significantly different. The authors found high overall compliance with ERAS process measures (91.4%) but variation in compliance according to phase of care. The highest compliance occurred during the preoperative phase (94.71% ± 2.88%), and the lowest compliance occurred during the postoperative phase of care (85.4% ± 5.7%).

CONCLUSIONS

OFA within an ERAS pathway for lumbar spinal decompression represents an opportunity to minimize perioperative opioid exposure without adversely affecting pain control or recovery. This study reveals opportunities for patient and provider education to reinforce ERAS and highlights the postoperative phase of care as a time when resources should be focused to increase ERAS adherence.

Regional and Multimodal Analgesia to Reduce Opioid Use After Total Joint Arthroplasty: A Narrative Review

BACKGROUND

Elective total joint arthroplasty may be a gateway to long-term opioid use.

QUESTIONS/PURPOSE

We sought to review the literature on multimodal and regional analgesia as a strategy to minimize perioperative opioid use and control pain in patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA).

METHODS

We conducted a narrative review to assess the state of the evidence informing opioid-sparing analgesics for THA and TKA. A PubMed search was conducted for English-language articles published before April 2018. We preferentially included well-designed randomized controlled trials, systematic reviews, and meta-analyses. Where the highest levels of evidence were not yet apparent, we evaluated retrospective and/or observational studies.

RESULTS

Multimodal analgesia emphasizing nonsteroidal anti-inflammatory agents and acetaminophen is associated with decreases in perioperative opioid use for THA and TKA. Regional analgesia, including peripheral nerve blocks and local infiltration analgesia, is also associated with decreased perioperative opioid use for THA and TKA. Emerging topics in post-arthroplasty analgesia include (1) the value of nonsteroidal anti-inflammatory drugs, (2) the use of peripheral nerve catheters and extended-release local anesthetics to prolong the duration of opioid-free analgesia, and (3) novel peripheral nerve blocks, exemplified by the IPACK (interspace between the popliteal artery and posterior capsule of the knee) block for TKA.

CONCLUSIONS

The use of multimodal analgesia with regional techniques may decrease perioperative opioid use for patients undergoing THA and TKA. These techniques should be part of a comprehensive perioperative plan to promote adequate analgesia while minimizing overall opioid exposure.

Interdisciplinary Mitigation of Opioid Misuse in Musculoskeletal Patients

BACKGROUND

The opioid prescribing patterns of orthopedic surgeons have been shown to play a role in exacerbating rates of opioid misuse among post-surgical patients. Demonstrable success has been appreciated by combining policy-level approaches and clinical education-based strategies to inform patients of alternative modalities of post-operative analgesia.

QUESTIONS/PURPOSES

The purpose of this review was to address two questions: What are the most substantiated measures orthopedic surgeons can take to limit opioid misuse or addiction among their patients? What advantages are gained in orthopedic surgeons' collaborating with other healthcare professionals with influence over patients' post-operative opioid exposure?

METHODS

We searched two databases for articles on multidisciplinary policy-based solutions to mitigating the opioid overdose crisis among musculoskeletal patients. Articles produced from the search were searched for further evidence supporting the use of standardized clinical and administrative protocols in mitigating opioid misuse within this patient population. Successful approaches to mitigating misuse of opioids in this demographic were synthesized from recurring themes in the studies.

RESULTS

Multiple articles support orthopedic surgeons being aware of the risk factors for chronic opioid use among their patients, as well as multidisciplinary strategies involving orthopedic surgeons and other healthcare/governmental professionals to address the burden of the opioid crisis on surgical patients.

CONCLUSIONS

Addressing the misuse of opioids among orthopedic patients requires appropriate prescribing practices and long-term support of patients. Collaboration between surgeons and policymaking entities is recognized as an effective population-wide approach to preventing opioid dependence, misuse, and addiction.

Fighting Back: Institutional Strategies to Combat the Opioid Epidemic: A Systematic Review

BACKGROUND

Current research on opioid use within orthopedic surgery has focused on efforts to identify patients at risk for chronic opioid use. Studies addressing prevention of opioid misuse related to orthopedic care are lacking. Evidence-based interventions to reduce the reliance on opioids for post-operative pain relief will be a key component of any comprehensive institutional opioid policy.

QUESTIONS/PURPOSES

The purpose of this systematic review was to evaluate institutional strategies that reduce opioid administration or consumption after orthopedic surgery.

METHODS

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, a search was conducted of the PubMed database for English-language articles that analyzed interventions by physicians, nurses, pharmacists, physical therapists, or other hospital staff to reduce post-operative opioid use or narcotic prescription amounts after surgery. Studies that contained objective outcome measures (i.e., no expert opinion articles) were selected. Investigations on the effect of pharmacologic adjuvants, cryotherapy, or regional nerve blockades on opioid use were excluded.

RESULTS

The initial search yielded 6598 titles, of which 13 full-text articles were ultimately selected for inclusion in this systematic review. The review identified two major categories of interventions-patient-focused and provider-focused (e.g., physicians, nurses, physical therapists, pharmacists). Formal patient education programs were most effective in reducing opioid use. On the provider side, prescribing guidelines appear to decrease the overall number of pills prescribed, often without changes in patient satisfaction or requests for refills.

CONCLUSIONS

Researchers are just beginning to establish the most effective ways for institutions to reduce opioid use and promote responsible post-operative prescribing. Institutional prescribing guidelines, standardized bedside pain-management programs, and formal patient education curriculums are all evidence-based interventions that can achieve these goals. The available research also supports an interprofessional approach in any institutional opioid-reduction strategy.
