Long-Term Opioid Prescriptions After Spine Surgery: A Meta-Analysis of Prevalence and Risk Factors

Preoperative Narcotic Education in Spine Surgery: A Retrospective Study

Background/Objectives: The objective of this study was to determine whether preoperative opioid education reduces opioid consumption after spine surgery and which educational methods are the most effective. Orthopedists are the most likely to prescribe opioids among all specialists. To alleviate the prescription opioid crisis, studies have identified ways to taper narcotic dosage and use following surgery. The role of preoperative education and its varying modalities on opioid consumption following spine surgery has yet to be reported in the literature. Methods: The study group received formal education describing the use of opioids, side effects, and alternatives to pain management. Patients were to choose their preferred modality of a 2 min narrated video and two handouts to be watched and read in their individual time, attending a small class led by a physician assistant where they watched the 2 min narrated video along with reading the two handouts or receiving a one-on-one session with the treating spine surgeon. Meanwhile, the control group received standard preoperative education. Refill prescriptions were collected from patients' electronic medical record charts at the 2-week, 1-month, 3-month, and 6-month postoperative follow-ups. The primary outcome measure was morphine equivalents (MME) of prescription opioids at six months following spine surgery. Results: At 2 weeks postoperatively, there were no statistically significant differences between patients who received any formal narcotic education and those who did not. At 1 and 3 months postoperatively, the video education group (p-value < 0.001), class education group (p-value < 0.001), and the one-on-one education group (p-value < 0.05) all had significant reductions in opioid consumption. At 6 months postoperatively, only the video education group (p-value < 0.001) and the class education group (p-value < 0.01) had significant reductions in opioid consumption. Conclusions: A two-fold approach with a video and handouts significantly decreases the prescription dosage at six months postoperatively and allows for early opioid cessation after undergoing spine surgery.

The impact of mental health on shoulder arthroplasty and rotator cuff repair: a meta-analysis

BACKGROUND

The aim of this study was to evaluate the impact of mental health attributes, such as the presence of psychiatric comorbidities or psychological comorbidities (low resilience), on outcomes after rotator cuff repair (RCR) and total shoulder arthroplasty (TSA).

METHODS

PubMed, Cochrane, and Google Scholar (results pages 1-20) were searched up to November 2023. Mental health problems of interest included the presence of psychiatric comorbidities (depression, anxiety) or indicators of poor psychological functioning, such as low resilience or the presence of distress. Patients were assigned to poor or good mental health groups in this study based on their grouping in the original study.

RESULTS

Fourteen studies were included in the meta-analysis. Patients with good mental health had greater improvements in postoperative American Shoulder and Elbow Surgeons and Simple Shoulder Test scores in the TSA cohort (P=0.003 and P=0.01), RCR cohort (P<0.001), and the combined TSA and RCR cohort (P<0.001). No difference was found in visual analog scale score, satisfaction, external rotation, or flexion between the two mental health groups. Patients with poor mental health undergoing RCR experienced higher rates of adverse events and transfusions (P<0.001). Patients with poor mental health also had greater rates of revision and emergency department visits in the TSA cohort (P<0.001), RCR cohort (P=0.05 and P=0.03), and combined cohort (P<0.001). Patients with poor mental health undergoing TSA had a higher rate of re-admission (P<0.001).

CONCLUSIONS

Patients with poor preoperative mental health showed inferior patient-reported outcome scores and increased rates of adverse events, revisions, and re-admissions. Level of evidence: III.

Navigating Opioid Alternatives in Spine Surgery: A Comprehensive Review

The opioid crisis has significantly impacted pain management practices in spine surgery, prompting a critical reassessment of traditional approaches. While opioids have historically been effective for post-operative pain relief, their widespread use has led to substantial public health challenges, including addiction and overdose. This review explores alternative strategies to opioids in spine surgery, emphasizing non-opioid pharmacological options [e.g., nonsteroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, local anesthetics] and non-pharmacological interventions (e.g., physical therapy, cognitive-behavioral therapy). These alternatives aim to mitigate opioid-related risks while optimizing patient outcomes. Key findings highlight these approaches' efficacy, safety considerations, and practical implications. Recommendations include personalized pain management plans and multidisciplinary collaboration to enhance care delivery. Future directions suggest advancing research in innovative pain management technologies and promoting evidence-based practices to mitigate opioid dependence. Ultimately, integrating these strategies into clinical practice is essential for addressing the opioid crisis and ensuring quality care in spine surgery.

Opioid Use Prior to Adult Spine Deformity Correction Surgery is Associated With Worse Pre- and Postoperative Back Pain and Prolonged Opioid Demands

STUDY DESIGN

Prospective multicenter database post-hoc analysis.

OBJECTIVES

Opioids are frequently prescribed for painful spinal conditions to provide pain relief and to allow for functional improvement, both before and after spine surgery. Amidst a current opioid epidemic, it is important for providers to understand the impact of opioid use and its relationship with patient-reported outcomes. The purpose of this study was to evaluate pre-/postoperative opioid consumption surrounding ASD and assess patient-reported pain outcomes in older patients undergoing surgery for spinal deformity.

METHODS

Patients ≥60 years of age from 12 international centers undergoing spinal fusion of at least 5 levels and a minimum 2-year follow-up were included. Patient-reported outcome scores were collected using the Numeric Rating Scale for back and leg pain (NRS-B; NRS-L) at baseline and at 2 years following surgery. Opioid use, defined based on a specific question on case report forms and question 11 from the SRS-22r questionnaire, was assessed at baseline and at 2-year follow-up.

RESULT

Of the 219 patients who met inclusion criteria, 179 (81.7%) had 2-year data on opioid use. The percentages of patients reporting opioid use at baseline (n = 75, 34.2%) and 2 years after surgery (n = 55, 30.7%) were similar (P = .23). However, at last follow-up 39% of baseline opioid users (Opi) were no longer taking opioids, while 14% of initial non-users (No-Opi) reported opioid use. Regional pre- and postoperative opioid use was 5.8% and 7.7% in the Asian population, 58.3% and 53.1% in the European, and 50.5% and 40.2% in North American patients, respectively. Baseline opioid users reported more preoperative back pain than the No-Opi group (7.0 vs 5.7, P = .001), while NRS-Leg pain scores were comparable (4.8 vs 4, P = .159). Similarly, at last follow-up, patients in the Opi group had greater NRS-B scores than Non-Opi patients (3.2 vs 2.3, P = .012), but no differences in NRS-Leg pain scores (2.2 vs 2.4, P = .632) were observed.

CONCLUSIONS

In this study, almost one-third of surgical ASD patients were consuming opioids both pre- and postoperatively world-wide. There were marked international variations, with patients from Asia having a much lower usage rate, suggesting a cultural influence. Despite both opioid users and nonusers benefitting from surgery, preoperative opioid use was strongly associated with significantly more back pain at baseline that persisted at 2-year follow up, as well as persistent postoperative opioid needs.

Nationwide Analysis of Risk Factors Related to Opioid Weaning Following Lumbar Decompression Surgery - A Retrospective Database Study

BACKGROUND

Opioids are often prescribed for patients who eventually undergo lumbar decompression. Given the potential for opioid-related morbidity and mortality, postoperative weaning is often a goal of surgery. The purpose of this study was to examine the relationship between preoperative opioid use and postoperative complete opioid weaning among lumbar decompression patients.

METHODS

We surveyed the IBM Marketscan Databases for patients who underwent lumbar decompression during 2008-2017, had >30 days of opioid use in the year preceding surgery, and consumed a daily average of >0 morphine milligram equivalents in the 3 months preceding surgery. We used multivariable logistic regression and marginal standardization to examine the association between preoperative opioid use duration, average daily dose, and their interactions with complete opioid weaning in the 10-12 months after surgery.

RESULTS

Of the 11,114 patients who met inclusion criteria, most (54.7%, n = 6083) had a preoperative average daily dose of 1-20 morphine milligram equivalents. Postoperatively, 6144 patients (55.3%) remained on opioids. For patients with >180 days of preoperative use, the adjusted probability of weaning increased as the preoperative dose decreased. Obesity increased the likelihood of weaning, whereas older age, several comorbidities, female sex, and Medicaid decreased the odds of weaning.

CONCLUSIONS

Patients who used opioids for longer preoperatively were less likely to completely wean following surgery. Among patients with >180 days of preoperative use, those with lower preoperative doses were more likely to wean. Weaning was also associated with several clinical and demographic factors. These findings may help shape expectations regarding opioid use following lumbar decompression.

Recovery Kinetics After Cervical Spine Surgery

STUDY DESIGN

Retrospective review of a prospectively maintained multisurgeon registry.

OBJECTIVE

To study recovery kinetics and associated factors after cervical spine surgery.

SUMMARY OF BACKGROUND DATA

Few studies have described return to activities cervical spine surgery. This is a big gap in the literature, as preoperative counseling and expectations before surgery are important.

MATERIALS AND METHODS

Patients who underwent either anterior cervical discectomy and fusion (ACDF) or cervical disk replacement (CDR) were included. Data collected included preoperative patient-reported outcome measures, return to driving, return to working, and discontinuation of opioids data. A multivariable regression was conducted to identify the factors associated with return to driving by 15 days, return to working by 15 days, and discontinuing opioids by 30 days.

RESULTS

Seventy ACDF patients and 70 CDR patients were included. Overall, 98.2% of ACDF patients and 98% of CDR patients returned to driving in 16 and 12 days, respectively; 85.7% of ACDF patients and 90.9% of CDR patients returned to work in 16 and 14 days; and 98.3% of ACDF patients and 98.3% of CDR patients discontinued opioids in a median of seven and six days. Though not significant, minimal (odds ratio (OR)=1.65) and moderate (OR=1.79) disability was associated with greater odds of returning to driving by 15 days. Sedentary work (OR=0.8) and preoperative narcotics (OR=0.86) were associated with decreased odds of returning to driving by 15 days. Medium (OR=0.81) and heavy (OR=0.78) intensity occupations were associated with decreased odds of returning to work by 15 days. High school education (OR=0.75), sedentary work (OR=0.79), and retired/not working (OR=0.69) were all associated with decreased odds of discontinuing opioids by 30 days.

CONCLUSIONS

Recovery kinetics for ACDF and CDR are comparable. Most patients return to all activities after ACDF and CDR within 16 days. These findings serve as an important compass for preoperative counseling.

Efficacy and Safety of Direct Oral Anticoagulants (DOACs) Versus Warfarin in Atrial Fibrillation Patients with Prior Stroke: a Systematic Review and Meta-analysis

BACKGROUND

The purpose of this meta-analysis was to compare efficacy and safety of direct oral anticoagulants (DOACs) to warfarin for secondary stroke prevention among adult patients with atrial fibrillation and prior stroke.

METHODS

Major repositories were screened for randomized controlled trials (RCTs), RCT subgroups, and observational studies (OBSs, divided in claims and non-claims). Occurrences of ischemic stroke or transient ischemic attack, systemic embolism, all-cause mortality, intracranial hemorrhage (ICH), and major bleeding were outcomes of interest. Hazard ratios (HRs) and their confidence intervals (95%CIs) were pooled using random-effects models for each study design. Claims studies were analyzed separately from non-claims, while RCT subgroups were grouped with OBSs (non-claims) as the randomization was broken.

RESULTS

Of 8647 articles, 20 were included (one RCT, six RCT subgroups, nine claims, and four non-claims). Comparing DOACs to warfarin, pooled HRs (95%CI) were consistently in favor of DOACs although some did not reach statistical significance: for ischemic stroke, 0.84 (0.66-1.07) in claims; 0.90 (0.77-1.06) in non-claims and RCT subgroups; for systemic embolism, 0.77 (0.62-0.96) in claims; 0.86 (0.77-0.96) in non-claims and RCT subgroups; for all-cause mortality, 0.57 (0.33-0.99) in claims; 0.87 (0.79-0.96) in non-claims and RCT subgroups; for ICH, 0.72 (0.39-1.33) in claims; 0.51 (0.38-0.67) in non-claims and RCT subgroups; and for major bleeding, 0.86 (0.71-1.03) in claims; 0.90 (0.76-1.08) for non-claims and RCT subgroups.

CONCLUSION

DOACs were associated with better efficacy and safety profiles than warfarin in atrial fibrillation patients with prior stroke, more specifically a lower risk of systemic embolism, all-cause mortality, and ICH.

Continued Opioid Use and Adverse Events Following Provision of Opioids for Musculoskeletal Pain in the Emergency Department: A Systematic Review and Meta-Analysis

BACKGROUND

The prevalence of continued opioid use or serious adverse events (SAEs) following opioid therapy in the emergency department (ED) for musculoskeletal pain is unclear. The aim of this review was to examine the prevalence of continued opioid use and serious adverse events (SAEs) following the provision of opioids for musculoskeletal pain in the emergency department (ED) or at discharge.

METHODS

Records were searched from MEDLINE, EMBASE and CINAHL from inception to 7 October 2022. We included randomised controlled trials and observational studies enrolling adult patients with musculoskeletal pain who were administered and/or prescribed opioids in the ED. Continued opioid use and opioid misuse data after day 4 since ED discharge were extracted. Adverse events were coded using the Common Terminology Criteria for Adverse Events (CTCAE), and those rated as grades 3-4 (severe or life-threatening) and grade 5 (death) were considered SAEs. Risk of bias was assessed using the Quality in Prognosis Studies (QUIPS) tool.

RESULTS

Seventy-two studies were included. Among opioid-naïve patients who received an opioid prescription, 6.8-7.0% reported recent opioid use at 3-12 months after discharge, 4.4% filled ≥ 5 opioid prescriptions and 3.1% filled > 90-day supply of opioids within 6 months. The prevalence of SAEs was 0.02% [95% confidence interval (CI) 0, 0.2%] in the ED and 0.1% (95% CI 0, 1.5%) within 2 days. One study observed 42.9% of patients misused opioids within 30 days after discharge.

CONCLUSIONS

Around 7% of opioid-naïve patients with musculoskeletal pain receiving opioid therapy continue opioid use at 3-12 months after ED discharge. SAEs following ED administration of an opioid were uncommon; however, studies only monitored patients for 2 days.

Surgical prescription opioid trajectories among state Medicaid enrollees

OBJECTIVE

The objective of this study was to evaluate opioid use trajectories among a sample of 10,138 Medicaid patients receiving one of six index surgeries: lumbar spine, total knee arthroplasty, cholecystectomy, appendectomy, colon resection, and tonsillectomy.

DESIGN

Retrospective cohort.

SETTING

Administrative claims data.

PATIENTS AND PARTICIPANTS

Patients, aged 13 years and older, with 15-month continuous Medicaid eligibility surrounding index surgery, were selected from single-state Medicaid medical and pharmacy claims data for surgeries performed between 2014 and 2017.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Baseline comorbidities and presurgery opioid use were assessed in the 6 months prior to admission, and patients' opioid use was followed for 9 months post-discharge. Generalized linear model with log link and Poisson distribution was used to determine risk of chronic opioid use for all risk factors. Group-based trajectory models identified groups of patients with similar opioid use trajectories over the 15-month study period.

RESULTS

More than one in three (37.7 percent) patients were post-surgery chronic opioid users, defined as the dichotomous outcome of filling an opioid prescription 90 or more days after surgery. Key variables associated with chronic post-surgery opioid use include presurgery opioid use, 30-day post-surgery opioid use, and comorbidities. Latent trajectory modeling grouped patients into six distinct opioid use trajectories. Associates of trajectory group membership are reported.

CONCLUSIONS

Findings support the importance of surgeons setting realistic patient expectations for post-surgical opioid use, as well as the importance of coordination of post-surgical care among patients failing to fully taper off opioids within 1-3 months of surgery.

The Effectiveness of a Mindfulness-Based Intervention Integrated with Physical Therapy (MIND-PT) for Postsurgical Rehabilitation After Lumbar Surgery: A Protocol for a Randomized Controlled Trial as Part of the Back Pain Consortium (BACPAC) Research Program

BACKGROUND

Improving pain management for persons with chronic low back pain (LBP) undergoing surgery is an important consideration in improving patient-centered outcomes and reducing the risk of persistent opioid use after surgery. Nonpharmacological treatments, including physical therapy and mindfulness, are beneficial for nonsurgical LBP through complementary biopsychosocial mechanisms, but their integration and application for persons undergoing surgery for LBP have not been examined. This study (MIND-PT) is a multisite randomized trial that compares an enriched pain management (EPM) pathway that integrates physical therapy and mindfulness vs usual-care pain management (UC) for persons undergoing surgery for LBP.

DESIGN

Participants from military treatment facilities will be enrolled before surgery and individually randomized to the EPM or UC pain management pathways. Participants assigned to EPM will receive presurgical biopsychosocial education and mindfulness instruction. After surgery, the EPM group will receive 10 sessions of physical therapy with integrated mindfulness techniques. Participants assigned to the UC group will receive usual pain management care after surgery. The primary outcome will be the pain impact, assessed with the Pain, Enjoyment, and General Activity (PEG) scale. Time to opioid discontinuation is the main secondary outcome.

SUMMARY

This trial is part of the National Institutes of Health Helping to End Addiction Long-term (HEAL) initiative, which is focused on providing scientific solutions to the opioid crisis. The MIND-PT study will examine an innovative program combining nonpharmacological treatments designed to improve outcomes and reduce opioid overreliance in persons undergoing lumbar surgery.

Perioperative Factors Associated With Chronic Opioid Use After Spine Surgery

STUDY DESIGN

Retrospective case control.

OBJECTIVES

The purpose of the current study is to determine risk factors associated with chronic opioid use after spine surgery.

METHODS

In our single institution retrospective study, 1,299 patients undergoing elective spine surgery at a tertiary academic medical center between January 2010 and August 2017 were enrolled into a prospectively collected registry. Patients were dichotomized based on renewal of, or active opioid prescription at 3-mo and 12-mo postoperatively. The primary outcome measures were risk factors for opioid renewal 3-months and 12-months postoperatively. These primarily included demographic characteristics, operative variables, and in-hospital opioid consumption via morphine milligram equivalence (MME). At the 3-month and 12-month periods, we analyzed the aforementioned covariates with multivariate followed by bivariate regression analyses.

RESULTS

Multivariate and bivariate analyses revealed that script renewal at 3 months was associated with black race (P = 0.001), preoperative narcotic (P < 0.001) or anxiety/depression medication use (P = 0.002), and intraoperative long lumbar (P < 0.001) or thoracic spine surgery (P < 0.001). Lower patient income was also a risk factor for script renewal (P = 0.01). Script renewal at 12 months was associated with younger age (P = 0.006), preoperative narcotics use (P = 0.001), and ≥4 levels of lumbar fusion (P < 0.001). Renewals at 3-mo and 12-mo had no association with MME given during the hospital stay or with the usage of PCA (P > 0.05).

CONCLUSION

The current study describes multiple patient-level factors associated with chronic opioid use. Notably, no metric of perioperative opioid utilization was directly associated with chronic opioid use after multivariate analysis.

Postoperative Opioid Use Among Opioid-Naive Cannabis Users Following Single-Level Lumbar Fusions

BACKGROUND

As the literature grows on opioid use, the impact of simultaneous cannabis use has hitherto been mostly unexplored. In this study, we assessed the effects of cannabis use on postoperative opioid utilization in opioid-naive patients undergoing single level fusions of the lumbar spine.

METHODS

Using an all-payer claims database, the medical records of 91 million patients were analyzed to identify patients who had undergone single level lumbar fusions between January 2010 and October 2020. Rates of opioid utilization at 6 months following index procedure (morphine milligram equivalents/day), the development of opioid use disorder (OUD), and the rates of opioid overuse were assessed.

RESULTS

Following examination of 87,958 patient records, 454 patients were matched and distributed equally into cannabis user and noncannabis user cohorts. At 6 months following index procedure, cannabis users were equal to nonusers in their rates of prescribed opioid utilization (49.78%, P > 0.99). Cannabis users used smaller daily dosages compared to nonusers (51.1 ± 35.05 vs. 59.72 ± 41, P = 0.003). On the other hand, the proportion of patients diagnosed with OUD was found to be significantly higher among patients using cannabis (18.94% vs. 3.96%, P < 0.0001).

CONCLUSIONS

Compared to noncannabis users, opioid-naive patients who are cannabis users undergoing lumbar spinal fusions are at a higher risk of developing opioid dependence following surgery, despite having decreased daily dosages of opioids overall. Further studies should explore the factors associated with the development of OUD and the details of concurrent marijuana use to effectively treat pain while limiting the potential for abuse.

Opioid Use Patterns in a Statewide Adult Medicaid Population Undergoing Elective Lumbar Spine Surgery

STUDY DESIGN

Retrospective administrative database review.

OBJECTIVE

Analyze patterns of opioid use in patients undergoing lumbar surgery and determine associated risk factors in a Medicaid population.

SUMMARY OF BACKGROUND DATA

Opioid use in patients undergoing surgery for degenerative lumbar spine conditions is prevalent and impacts outcomes. There is limited information defining the scope of this problem in Medicaid patients.

MATERIALS AND METHODS

Longitudinal cohort study of adult South Carolina (SC) Medicaid patients undergoing lumbar surgery from 2014 to 2017. All patients had continuous SC Medicaid coverage for 15 consecutive months, including six months before and nine months following surgery. The primary outcome was a longitudinal assessment of postoperative opioid use to determine trajectories and group-based membership using latent modeling. Univariate and multivariable modeling was conducted to assess risk factors for group-based trajectory modeling and chronic opioid use (COU).

RESULTS

A total of 1455 surgeries met inclusion criteria. Group-based trajectory model demonstrated patients fit into five groups; very low use (23.4%), rapid wean following surgery (18.8%), increasing use following surgery (12.9%), slow wean following surgery (12.6%) and sustained high use (32.2%). Variables predicting membership in high opioid use included preoperative opioid use, younger age, longer length of stay, concomitant medications, and readmissions. More than three quarter of patients were deemed COUs (76.4%). On bivariate analysis, patients with degenerative disk disease were more likely to be COUs (24.8% vs. 18.6%; P =0.0168), more likely to take opioids before surgery (88.5% vs. 61.9%; P <0.001) and received higher amounts of opioids during the 30 days following surgery (mean morphine milligram equivalents 59.6 vs. 25.1; P <0.001).

CONCLUSIONS

Most SC Medicaid patients undergoing lumbar elective lumbar spine surgery were using opioids preoperatively and continued long-term use postoperatively at a higher rate than previously reported databases. Preoperative and perioperative intake, degenerative disk disease, multiple prescribers, depression, and concomitant medications were significant risk factors.

Impact of Affective Disorders on Inpatient Opioid Consumption and Hospital Outcomes Following Open Posterior Spinal Fusion for Adult Spine Deformity

OBJECTIVE

Affective disorders (ADs) are common and have a profound impact on surgical recovery, though few have studied the impact of ADs on inpatient narcotic consumption. The aim of this study was to assess the impact of ADs on inpatient narcotic consumption and healthcare resource utilization in patients undergoing spinal fusion for adult spinal deformity.

METHODS

A retrospective cohort study was performed using the 2016-2017 Premier Healthcare Database. Adults who underwent adult spinal deformity surgery were identified using International Classification of Disease, Tenth Revision, codes. Patients were grouped based on comorbid diagnosis of an AD. Demographics, comorbidities, intraoperative variables, complications, length of stay, admission costs, and nonroutine discharge rates were assessed. Increased inpatient opioid use was categorized by morphine milligram equivalents consumption greater than the 75th percentile. Multivariate regression analysis was used to identify predictors of increased healthcare recourse utilization.

RESULTS

Of the 1831 study patients, 674 (36.8%) had an AD. A smaller proportion of patients in the AD cohort were 65+ years of age (P = 0.001), while a greater proportion of patients in the AD cohort identified as non-Hispanic White (P < 0.001). A greater proportion of patients in the AD cohort had increased morphine milligram equivalents consumption (P < 0.001). The AD cohort also had a longer mean length of stay (P < 0.001). A greater proportion of patients in the AD cohort had nonroutine discharges (P = 0.039) and unplanned 30-day readmission (P = 0.041). On multivariate analysis, AD was significantly associated with increased cost (odds ratio: 1.61, P < 0.001) and nonroutine discharge (odds ratio: 1.36, P = 0.035).

CONCLUSIONS

ADs may be associated with increased inpatient opioid consumption and healthcare resource utilization.

Long-term opioid medication profile of European adult spinal deformity patients: minimum five years follow-up study

BACKGROUND CONTEXT

There remains significant variability in the use of postoperative opioids. On one end, it is proven that appropriate pain control is a critical aspect of patient management; on the other end, past few decades have been associated with major increases in opioid-related overdoses and addiction treatment. We hypothesized that several pre- and postoperative risk factors affecting long-term opioid use could be identified.

PURPOSE

Evaluation of factors associated with minimum 5-year postoperative opioid use following adult spinal deformity surgery.

STUDY DESIGN/SETTING

Prospectively followed study group database.

PATIENT SAMPLE

Adult spinal deformity patients who underwent elective spine surgery between 2009 and 2016 were included.

OUTCOME MEASURES

Opioid usage or otherwise at minimum 5 years follow-up. Use of nonopioid analgesics, weak and strong opioids METHODS: Retrospective analysis of patients undergoing elective spinal deformity surgery. A total of 37 factors comprising patient characteristics, radiographic measurements, operative details, preoperative and early postoperative opioid use, and mechanical complications and revisions were analyzed. Details on identified factors were provided.

RESULTS

A total of 265 patients (215F, 50M) from five sites were included. The mean follow-up duration was 68.4±11.7 (60-102) months. On average, 10.6±3.5 levels were fused. Preoperatively, 64 (24.2%) patients were using opioids. The rate of opioid users increased to 33.6% at 6 weeks and decreased to 21.5% at 6 months. During follow-up, there were patients who discontinued opioids, while others have started and/or restarted using opioids. As a result, 59 (22.3%) patients were still on opioids at the latest follow-up. Multivariate analyses showed that factors independently affecting opioid use at an average of 68 months postoperatively, in order of significance, were opioid use at sixth weeks, preoperative opioid use and opioid use at sixth months with the odds ratios of 2.88, 2.51, and 2.38 respectively. At these time points, factors such as age, number of comorbidities, tobacco use, the time of the last prior spine surgery and postoperative sagittal plane alignment affected opioid usage rates.

CONCLUSIONS

Opioid usage at 6 weeks was found to be more predictive of long-term opioid use compared to preoperative use. Patients should be well informed to have realistic expectations regarding opioid use when considering adult spinal deformity surgery.

Preoperative Patient-Reported Data Indicate the Risk of Prolonged Opioid Use After Hand and Upper Extremity Surgeries

PURPOSE

Opioids play an important role in pain management after surgery but also increase the risk of prolonged opioid use in patients. The identification of patients who are more likely to use opioids after intended short-term treatment is critical for employing alternative management approaches or targeted interventions for the prevention of opioid-related problems. We used patient-reported data (PRD) and electronic health record information to identify factors predictive of prolonged opioid use after surgery.

METHODS

We used our institutional registry containing data on all patients who underwent elective upper extremity surgeries. We evaluated factors associated with prolonged opioid use in the cohort from the year 2018 to 2019. We then validated our results using the 2020 cohort. The predictive variables included preoperative PRD and electronic health record data. Opioid use was determined based on patient reports and/or filled opioid prescriptions 3 months after surgery. We conducted bivariate regression, followed by multivariable regression analyses, and model validation using area under the receiver operating curve.

RESULTS

We included 2,114 patients. In our final model on the 2018-2019 electronic health records and PRD data (n = 1,589), including numerous patient-reported outcome questionnaire scores, patients who were underweight and had undergone trauma-related surgery had higher odds of being on opioids at 3 months. Additionally, each 5-unit decrease in the preoperative Patient-Reported Outcomes Measurement Information System Global Physical Health score was associated with a 30% increased odds of being on opioids at 3 months. The area under the receiver operating curve of our model was 70.4%. On validation using data from the 2020 cohort, the area under the receiver operating curve was 60.3%. The Hosmer-Lemeshow test indicated a good fit.

CONCLUSIONS

We found that preoperative questionnaire scores were associated with prolonged postoperative opioid use, independent of other variables. Furthermore, PRD may provide unique patient-level insights, alongside other factors, to improve our understanding of postsurgical pain management.

Postoperative Pain Management Following Orthopedic Spine Procedures and Consequent Acute Opioid Poisoning: An Analysis of New York State From 2009 to 2018

OBJECTIVE

Considering the high rates of opioid usage following orthopedic surgeries, it is important to explore this in the setting of the current opioid epidemic. This study examined acute opioid poisonings in postoperative spine surgery patients in New York and the rates of poisonings among these patients in the context of New York's 2016 State legislation limiting opioid prescriptions.

METHODS

Claims for adult patients who received specific orthopedic spine procedures in the outpatient setting were identified from 2009 to 2018 in the New York Statewide Planning and Research Cooperative System (SPARCS) database. Patients were followed to determine if they presented to the emergency department for acute opioid poisoning postoperatively. Multivariable logistic regression was performed to evaluate the effect of patient demographic factors on the likelihood of poisoning. The impact of the 2016 New York State Public Health Law Section 3331, 5. (b), (c) limiting opioid analgesic prescriptions was also evaluated by comparing rates of poisoning prelegislation and postlegislation enactment.

RESULTS

A total of 107,456 spine patients were identified and 321 (0.3%) presented postoperatively to the emergency department with acute opioid poisoning. Increased age [odds ratio (OR)=0.954, P <0.0001] had a decreased likelihood of poisoning. Other race (OR=1.322, P =0.0167), Medicaid (OR=2.079, P <0.0001), Medicare (OR=2.9, P <0.0001), comorbidities (OR=3.271, P <0.0001), and undergoing multiple spine procedures during a single operative setting (OR=1.993, P <0.0001) had an increased likelihood of poisoning. There was also a significant reduction in rates of postoperative acute opioid poisoning in patients receiving procedures postlegislation with reduced overall likelihood (OR=0.28, P <0.0001).

CONCLUSION

There is a higher than national average rate of acute opioid poisonings following spine procedures and increased risk among those with certain socioeconomic factors. Rates of poisonings decreased following a 2016 legislation limiting opioid prescriptions. It is important to define factors that may increase the risk of postoperative opioid poisoning to promote appropriate management of postsurgical pain.

Engaging Education About Risks of Opioid Use With Patients Before Elective Surgery of the Lower Extremity Did Not Reduce Postoperative Opioid Utilization: A Randomized Controlled Trial

INTRODUCTION

After elective orthopaedic surgery, many individuals go on to become long-term opioid users. Mitigating this risk has become a priority for surgeons, other members of the medical care team, and healthcare systems. The purpose of this study was to compare opioid utilization after lower extremity orthopaedic surgery between patients who received an interactive video education session highlighting the risks of opioid use and those who did not.

METHODS

Patients undergoing elective surgery of the lower extremity in the orthopaedic clinic at the Brooke Army Medical Center between July 2015 and February 2017 were recruited at their preoperative appointment and randomized in a 1:1 ratio to receive a one-time interactive opioid education session or usual care education. Unique days' supply of opioids and unique prescriptions were compared using a generalized linear model. Individuals were also grouped by whether they had become long-term opioid users after surgery, and frequencies within each intervention group were compared.

RESULTS

There were 120 patients, 60 randomized to each group and followed for 1 year. There were no significant differences between opioid days' supply (mean diff = 8.33, 95% confidence interval -4.21 to 20.87) and unique prescriptions after surgery (mean diff = 0.45, 95% confidence interval -0.25 to 1.15). Most participants did not have any opioids past the initial 30 days after surgery, regardless of intervention (n = 77), and only three became long-term opioid users (one in usual care and two in interactive education). Sixteen in usual education and 18 in enhanced education filled at least one prescription in 6 months or later after the surgical procedure.

CONCLUSION

Opioid use beyond 30 days of surgery was no different for participants who received enhanced education compared with usual education. Few became long-term opioid users after surgery (2.5%), although 28.3% were still filling opioid prescriptions 6 months after surgery.

Dramatic Reduction in Opioid Prescribing for Common Outpatient Orthopaedic Lower Extremity Surgical Procedures at a Louisiana University-Based Safety-Net Hospital After Enactment of Opioid-Limiting State Legislation

INTRODUCTION

The opioid epidemic in the United States has been fueled by overprescribing opioids, which is particularly apparent in orthopaedics. Stakeholders, including state legislatures, have attempted to curb opioid overprescribing to reduce related abuse/dependence, overdose deaths, and diversion.

OBJECTIVE

To examine trends in opioid prescribing for common outpatient lower extremity orthopaedic surgeries in a population vulnerable to prolonged opioid use before and after the enactment of a 2017 Louisiana state law limiting opioid prescribing for acute pain.

METHODS

Eligible patients were adults who underwent one of the five most common outpatient lower extremity orthopaedic surgeries done during 2013 to 2018 at an urban tertiary care academic medical center. Excluded were prisoners and patients who required inpatient hospitalization, had no documented discharge opioid prescription, or filled an opioid prescription unrelated to their orthopaedic procedure within 30 days before surgery.

RESULTS

During 2013 to 2018, 655 surgical procedures were done in 655 eligible patients, of whom 49% were Black and 54% were insured by Medicaid. The mean morphine milligram equivalent per discharge prescription decreased by almost 70% from 2014 to 2018. A statistically significant decrease in the mean morphine milligram equivalent per discharge prescription was observed in 2018 versus all previous years (P < 0.0001 for all) and in 2017 versus all previous years (P < 0.0001 for all). Patients receiving at least one new opioid prescription after their discharge prescription declined over time from a high of 50% in 2013 to a low of 19.3% in 2018 with a statistically significant effect over time (P < 0.0001).

DISCUSSION

Opioid prescribing for patients undergoing common outpatient lower extremity orthopaedic surgeries who were at high risk for prolonged opioid use markedly declined after the enactment of a state law limiting first-time opioid prescriptions to 7 days, requiring physicians to check the state's Prescription Monitoring Program database and mandating continuing education for opioid prescribers.

Does Engaging Patients with Relevant Education About Long-Term Opioid Use Before Spine Surgery Affect Long-term Opioid Use? A Randomized Controlled Trial

STUDY DESIGN

Parallel-arm randomized controlled trial.

OBJECTIVE

To assess the effectiveness of an enhanced video education session highlighting risks of opioid utilization on longterm opioid utilization after spine surgery.

SUMMARY OF BACKGROUND DATA

Long-term opioid use occurs in more than half of patients undergoing spine surgery and strategies to reduce this use are needed.

METHODS

Patients undergoing spine surgery at Brooke Army Medical Center between July 2015 and February 2017 were recruited at their preoperative appointment, receiving the singlesession interactive video education or control at that same appointment. Opioid utilization was tracked for the full year after surgery from the Pharmacy Data Transaction Service of the Military Health System Data Repository. Self-reported pain also collected weekly for 1 and at 6months.

RESULTS

A total of 120 participants (40 women, 33.3%) with a mean age of 45.9 ± 10.6 years were randomized 1:1 to the enhanced education and usual care control (60 per group). In the year following surgery the cohort had a mean 5.1 (standard deviation [SD] 5.9) unique prescription fills, mean total days' supply was 88.3 (SD 134.9), and mean cumulative morphine milligrams equivalents per participant was 4193.0 (SD 12,187.9) within the year after surgery, with no significant differences in any opioid use measures between groups. Twelve individuals in the standard care group and 13 in the enhanced education group were classified with having long-term opioid utilization.

CONCLUSION

The video education session did not influence opioid use after spine surgery compared to the usual care control. There was no significant difference in individuals classified as long-term opioid users after surgery based on the intervention group. Prior opioid use was a strong predictor of future opioid use in this cohort. Strategies to improve education engagement, understanding, and decision- making continue to be of high importance for mitigating risk of long-term opioid use after spine surgery.Level of Evidence: 1.

More Than 1 in 3 Patients With Chronic Low Back Pain Continue to Use Opioids Long-term After Spinal Fusion: A Systematic Review

OBJECTIVE

A common expectation for patients after elective spine surgery is that the procedure will result in pain reduction and minimize the need for pain medication. Most studies report changes in pain and function after spine surgery, but few report the extent of opioid use after surgery. This systematic review aims to identify the rates of opioid use after lumbar spine fusion.

MATERIALS AND METHODS

PubMed, CINAHL, Cochrane Central Register of Controlled Trials, and Ovid Medline were searched to identify studies published between January 1, 2005 and June 30, 2020 that assessed the effectiveness of lumbar fusion for the management of low back pain.

RESULTS

Of 6872 abstracts initially identified, 329 studies met the final inclusion criteria, and only 32 (9.7%) reported any postoperative opioid use. Long-term opioid use after surgery persists for more than 1 in 3 patients with usage ranging from 6 to 85.9% and a pooled mean of 35.0% based on data from 21 studies (6.4% of all lumbar fusion studies).

DISCUSSION

Overall, opioid use is not reported in the majority of lumbar fusion trials. Patients may expect a reduced need for opioid-based pain management after surgery, but the limited data available suggests long-term use is common. Lack of consistent reporting of these outcomes limits definitive conclusions regarding the efficacy of spinal fusion for reducing long-term opioid. Patient decisions about undergoing surgery may be altered if they had realistic expectations about rates of postsurgical opioid use. Spine surgery trials should track opioid utilization out to a minimum of 6 months after surgery as a core outcome.

An Update on Postoperative Opioid Use and Alternative Pain Control Following Spine Surgery

Opioids are commonly prescribed postoperatively for pain control, especially in spine surgery. Not only does this pose concerns for potential abuse, but it also has been shown to worsen certain outcomes. Risk factors for increased use include preoperative opioid use, female sex, psychiatric diagnoses, and drug and alcohol use. Over the past few decades, there have been increasing efforts mostly spearheaded by governmental agencies to decrease postoperative opioid use via opioid prescription limitation laws regulating the number of days and amounts of analgesics prescribed and promotion of the use of enhanced recovery after surgery (ERAS) protocols, multimodal pain regimens, epidural catheters, and ultrasound-guided peripheral nerve blocks. These strategies collectively have been efficacious in decreasing overall opioid use and better controlling patients' postoperative pain while simultaneously improving other outcomes such as postoperative nausea, vomiting, and length of stay. With an aging population undergoing an increasing number of spinal surgeries each year, it is now more important than ever to continue these efforts to improve the quality and safety of pain control methods after spinal surgery and limit the transition of acute management to the development of opioid dependence and addiction long-term.
