Notable Variability in Opioid-prescribing Practices After Common Orthopaedic Procedures

Access to an Educational Video Preoperatively Has No Effect on Postoperative Opioid Use After Arthroscopic Partial Meniscectomy of the Knee: A Prospective Cohort Study

Purpose

To determine whether access to a website with an educational video would decrease postoperative opioid use in patients undergoing arthroscopic partial meniscectomy.

Methods

Enrolled patients who underwent arthroscopic partial meniscectomy at a single center were randomized to either the intervention or control group prior to surgery. The intervention group received a card with access to an online educational video regarding opioids with their postoperative instructions; the control group did not. The online video was just over 5 minutes long and contained general information about the dangers of opioid use, how to safely dispose of unused opioids, and local support contact information. Data were collected by telephone 10 to 14 days postoperatively and analyzed with GraphPad Prism version 9.5.0. Patient characteristics including age, sex, body mass index, allergies, smoking, depression, alcohol abuse, American Society of Anesthesiologists level, diagnosis of chronic obstructive pulmonary disease, hypertension, diabetes, substance abuse, employment status, workers' compensation, and sports participation were analyzed and correlated with postoperative opioid use.

Results

A total of 166 patients were included in this study, with 78 in the control group and 88 in the intervention group. Mean number of pills consumed was 3 in the control group and 2.2 in the intervention group. This difference did not reach statistical significance. Patients who were obese, smokers, or diagnosed with depression both consumed more opioids and were less likely to take no narcotics postoperatively. Patients who participated in sports consumed fewer total opioids on average than those who did not. Subgroup analysis of patients with higher risk factors did not show a difference between the control and intervention groups in the average amount of opioid used or the likelihood of using no narcotics. Among all patients, 82 (49%) used no narcotics postoperatively and 90% used 8 or fewer tablets.

Conclusions

Directing patients to an educational website and video is not an effective tool in decreasing opioid consumption. Patients undergoing arthroscopic meniscectomy who are obese, active smokers, and clinically depressed or do not participate in sports are likely to use more postoperative narcotics. Regardless of access to the online educational video, half of patients used no narcotics.

Opioid utilization after orthopaedic trauma hospitalization among Medicaid-insured adults

Opioids are vital to pain management and sedation after trauma-related hospitalization. However, there are many confounding clinical, social, and environmental factors that exacerbate pain, post-injury care needs, and receipt of opioid prescriptions following orthopaedic trauma. This retrospective study sought to characterize differences in opioid prescribing and dosing in a national Medicaid eligible sample from 2010-2018. The study population included adults, discharged after orthopaedic trauma hospitalization, and receiving an opioid prescription within 30 days of discharge. Patients were identified using the International Classification of Diseases (ICD-9; ICD-10) codes for inpatient diagnosis and procedure. Filled opioid prescriptions were identified from National Drug Codes and converted to morphine milligram equivalents (MME). Opioid receipt and dosage (e.g., morphine milligram equivalents [MME]) were examined as the main outcomes using regressions and analyzed by year, sex, race/ethnicity, residence rurality-urbanicity, and geographic region. The study population consisted of 86,091 injured Medicaid-enrolled adults; 35.3% received an opioid prescription within 30 days of discharge. Male patients (OR = 1.12, 95% CI: 1.07-1.18) and those between 31-50 years of age (OR = 1.15, 95% CI: 1.08-1.22) were found to have increased odds ratio of receiving an opioid within 30 days of discharge, compared to female and younger patients, respectively. Patients with disabilities (OR = 0.75, 95% CI: 0.71-0.80), prolonged hospitalizations, and both Black (OR = 0.87, 95% CI: 0.83-0.92) and Hispanic patients (OR = 0.72, 95% CI: 0.66-0.77), relative to white patients, had lower odds ratio of receiving an opioid prescription following trauma. Additionally, Black and Hispanic patients received lower prescription doses compared to white patients. Individuals hospitalized in the Southeastern United States and those between the ages of 51-65 age group were found to be prescribed lower average daily MME. There were significant variations in opioid prescribing practices by race, sex, and region. National guidelines for use of opioids and other pain management interventions in adults after trauma hospitalization may help limit practice variation and reduce implicit bias and potential harms in outpatient opioid usage.

Reductions in sustained prescription opioid use within the US between 2017 and 2021

Over the last decade, various efforts have been made to curtail the opioid crisis. The impact of these efforts, since the onset of the COVID-19 pandemic, has not been well characterized. We sought to develop national estimates of the prevalence of sustained prescription opioid use for a time period spanning the COVID-19 pandemic (2017-2021). We used TRICARE claims data (fiscal year 2017-2021) to identify patients who were prescription opioid non-users prior to receipt of a new opioid medication. We evaluated eligible patients for subsequent sustained prescription opioid use. The prevalence of sustained prescription opioid use during 2020-2021 was compared to 2017-2019. We performed multivariable logistic regression analyses to adjust for confounding. We performed secondary analyses that accounted for interactions between the time period and age, as well as a proxy for socioeconomic status. We determined there was a 68% reduction in the odds of sustained prescription opioid use (OR 0.32; 95% CI 0.27, 0.38; p < 0.001) in 2020-2021 as compared to 2017-2019. Significant reductions were identified across all US census divisions and all patient age groups. In both time periods, the plurality of encounters associated with initial receipt of an opioid that culminated in sustained prescription opioid use were associated with non-specific primary diagnoses. We found significant reductions in sustained prescription opioid use in 2020-2021 as compared to 2017-2019. The persistence of prescribing behaviors that result in issue of opioids for poorly characterized conditions remains an area of concern.

Detroit Interventional Pain Assessment Scale: A Pain Score and Method for Measuring and Evaluating Post-Operative Pain Management-A Prospective Study

Background and Objectives: Orthopedic surgeons commonly prescribe opioids, surpassing all medical specialties. Our objective was to develop a pain management scale that captures medication use, patient-reported pain scores, and helps orthopedic surgeons evaluate their post-operative prescribing practice. Materials and Methods: An IRB-approved prospective study followed 502 post-operative orthopedic surgery patients over a six-month period. All patients were surveyed in an orthopedic clinic at a Level 1 US Trauma Center, during a routine follow-up. Patient pain satisfaction was assessed using the validated Interventional Pain Assessment (IPA) scale, which uses three categories: 0 (no pain), 1 (tolerable pain), and 2 (intolerable pain). Daily narcotic use was translated to morphine milligram equivalents (MMEs) using the Michigan Automated Prescription System (MAPS) narcotics registry. When patient pain satisfaction and narcotic usage were combined, this scale was called the Detroit Interventional Pain Assessment (DIPA) scale. Results: The five classes based on common prescription and usage of narcotics in this cohort include the following: A (no pain medication), B (over-the-counter medication), C (occasional use of short-acting narcotics 1-30 MMEs), D (consistent/regular use of short-acting narcotics 31-79 MMEs), and E (long-duration or stronger short-acting narcotics 80+ MMEs). Patients were most satisfied with their pain management at six weeks (80.5%) and three months (75.65%), and least satisfied at two weeks (62.5%) and six months (60.9%). Additional information displayed on the DIPA graph revealed there was a significant decrease in the percentage of patients on narcotics at two weeks (65.2%) to six months (32.6%) at p < 0.001. Conclusions: The DIPA pain scale shows the relationship between patient pain perception and opioid prescription/usage, while also tracking prescriber tendencies. Providers were able to visualize their post-operative pain management progression at each designated clinic visit with corresponding alphabetical daily MME categories. In this study, results suggest that surgeons were not effective at managing the pain of patients at two weeks post-operative, which is attributed to an inadequate number of pain pills prescribed upon discharge. Overall, the DIPA graph signaled that better pain management interventions are necessitated in periods with lower efficiency scores.

Post-total joint arthroplasty opioid prescribing practices vary widely and are not associated with opioid refill: an observational cohort study

INTRODUCTION

Optimized health system approaches to improving guideline-congruent care require evaluation of multilevel factors associated with prescribing practices and outcomes after total knee and hip arthroplasty.

MATERIALS AND METHODS

Electronic health data from patients who underwent a total knee or hip arthroplasty between January 2016-January 2020 in the Military Health System Data were retrospectively analyzed. A generalized linear mixed-effects model (GLMM) examined the relationship between fixed covariates, random effects, and the primary outcome (30-day opioid prescription refill).

RESULTS

In the sample (N = 9151, 65% knee, 35% hip), the median discharge morphine equivalent dose was 660 mg [450, 892] and varied across hospitals and several factors (e.g., joint, race and ethnicity, mental and chronic pain conditions, etc.). Probability of an opioid refill was higher in patients who underwent total knee arthroplasty, were white, had a chronic pain or mental health condition, had a lower age, and received a presurgical opioid prescription (all p < 0.01). Sex assigned in the medical record, hospital duration, discharge non-opioid prescription receipt, discharge morphine equivalent dose, and receipt of an opioid-only discharge prescription were not significantly associated with opioid refill.

CONCLUSION

In the present study, several patient-, care-, and hospital-level factors were associated with an increased probability of an opioid prescription refill within 30 days after arthroplasty. Future work is needed to identify optimal approaches to reduce unwarranted and inequitable healthcare variation within a patient-centered framework.

A Review of Federal and Statewide Guidelines and Their Effects on Orthopedics

In the past three decades, the use of opioids has risen tremendously. Pain was named the "fifth patient vital sign" in the 1990s, and from that point, opioid usage has continued to grow throughout the 2010s leading to its recognition as a crisis. The United States is responsible for 80% of the global opioid usage while only accounting for less than 5% of the global population. Previously opioids were mostly used to treat acute pain, however, opioids have been most recently used to manage chronic pain as well. The opioid crisis has presented new challenges in treating pain while preventing the abuse of these medications in a system that lacks standardization of treatment guidelines across the United States. Therefore, the authors of this review examine the current national recommendations to help manage the ongoing opioid crisis and explore how they may impact orthopedic patient care.

Opioid Prescription Patterns 90 Days After Arthroscopic Rotator Cuff Repair: A 10-Year National Database Analysis

Background

Arthroscopic rotator cuff repair (ARCR) is a common procedure that typically requires opioid prescription for postoperative pain management.

Purpose

To investigate the current prescription patterns and factors influencing 90-day postoperative opioid prescription trends for opioid-naïve patients who underwent ARCR.

Study Design

Case series; Level of evidence, 4.

Methods

Opioid-naïve adult patients who underwent ARCR between January 2010 and September 2020 and had a record of opioid prescriptions during the 90-day postoperative period were identified in the PearlDiver Mariner91 national administrative database. Exclusions included patients with prior shoulder procedures, a history of chronic pain, and opioid prescription records dated earlier than 4 weeks before surgery. Covariates included age group, sex, Elixhauser Comorbidity Index, and prescriber specialty (orthopaedic or nonorthopaedic). The primary outcome-90-day postoperative morphine milligram equivalents (MMEs) prescribed per patient-was compared using univariate and multivariate regression analyses, and 90-day postoperative opioid prescription trends over the 10-year study period were analyzed with linear regression.

Results

In total, 55,345 ARCR cases were identified. The mean ± SD amount prescribed within the first 90 days was 742.4 ± 256.5 MMEs, and the median was 487.5 MMEs. Multivariate linear regression analysis predicted higher 90-day postoperative MMEs for female patients and younger patients (P < .01 for both). From 2010 to 2020, there was a 66% decrease in mean MME prescribed per patient (▵ = 660.4 MME; P < .01), with a mean reduction of 55.1 MME per patient per year. In 2020, the mean 90-day postoperative amount prescribed was 341.1 MME, which is equivalent to 51 tablets of 5-mg oxycodone (Percocet).

Conclusion

Female sex and younger age were predictors of more MME being prescribed after ARCR. While opioid prescriptions following ARCR have substantially decreased over the past decade, the amount prescribed warrants further attention.

Operative Versus Nonoperative Treatment of Acute Achilles Tendon Rupture: A Propensity Score-Matched Analysis of a Large National Dataset

Background

No consensus exists regarding the superiority of operative versus nonoperative management for Achilles tendon ruptures, as multiple randomized controlled trials conducted since the advent of early mobilization protocols have found outcomes for these 2 interventions to be more similar than were previously held.

Purpose

To use a large national database to (1) compare reoperation and complication rates between operative and nonoperative treatment of acute Achilles tendon ruptures and (2) evaluate trends in treatment and cost over time.

Study Design

Cohort study; Level of evidence, 3.

Methods

The MarketScan Commercial Claims and Encounters database was used to identify an unmatched cohort of 31,515 patients who sustained primary Achilles tendon ruptures between 2007 and 2015. Patients were stratified into operative and nonoperative treatment groups, and a propensity score-a matching algorithm-was used to establish a matched cohort of 17,996 patients (n = 8993 per treatment group). Reoperation rates, complications, and aggregate treatment costs were compared between groups with an alpha level of .05. A number needed to harm (NNH) was calculated from the absolute risk difference in complications between cohorts.

Results

The operative cohort experienced a significantly larger total number of complications within 30 days of injury (1026 vs 917; P = .0088). The absolute increase in cumulative risk was 1.2% with operative treatment, which resulted in an NNH of 83. Neither 1-year (1.1% [operative] vs 1.3% [nonoperative]; P = .1201) nor 2-year reoperation rates (1.9% [operative] vs 2% [nonoperative]; P = .2810) were significantly different. Operative care was more expensive than nonoperative care at 9 months and 2 years after injury; however, there was no difference in cost between treatments at 5 years. Before matching, the rate of surgical repair for Achilles tendon rupture remained stable, from 69.7% to 71.7% between 2007 and 2015, indicating little change in practice in the United States.

Conclusion

Results indicated no differences in reoperation rates between operative and nonoperative management of Achilles tendon ruptures. Operative management was associated with an increased risk of complications and higher initial costs, which dissipated over time. Between 2007 and 2015 the proportion of Achilles tendon ruptures managed operatively remained similar despite increasing evidence that nonoperative management of Achilles tendon rupture may provide equivalent outcomes.

A Safe Number of Perioperative Opioids to Reduce the Risk of New Persistent Usage Among Opioid-Naïve Patients Following Total Joint Arthroplasty

BACKGROUND

Higher initial opioid dosing increases the risk of prolonged opioid use following total joint arthroplasty (TJA), and the safe amounts to prescribe are unknown. We examined the relationship between perioperative opioid exposure and new persistent usage among opioid-naïve patients after total knee and hip arthroplasty.

METHODS

In this retrospective cohort study, 22,310 opioid-naïve patients undergoing primary TJA between 2018 and 2019 were identified within a commercial claims database. Perioperative opioid exposure was defined as total dose of opioid prescription in morphine milligram equivalents (MME) between 1 month prior to and 2 weeks after TJA. New persistent usage was defined as at least one opioid prescription between 90 and 180 days postoperatively. Multivariate regression analyses were performed to examine the relationship between the perioperative dosage group and the development of new persistent usage.

RESULTS

For the total patient cohort, 8.1% developed new persistent usage. Compared to patients who received <300 MME, patients who received 600-900 MME perioperatively had a 77% increased risk of developing new persistent usage (odds ratio 1.77, 95% CI, 1.44-2.17), and patients who received ≥1,200 MME perioperatively had a 285% increased risk (odds ratio 3.85, 95% CI, 3.13-4.74).

CONCLUSION

We found a dose-dependent association between perioperative MME and the risk of developing new persistent usage among opioid-naïve patients following TJA. We recommend prescribing <600 MME (equivalent to 80 pills of 5 mg oxycodone) during the perioperative period to reduce the risk of new persistent usage.

Prescription Patterns, Associated Factors, and Outcomes of Opioids for Operative Foot and Ankle Fractures: A Systematic Review

BACKGROUND

Pain management after foot and ankle surgery must surmount unique challenges that are not present in orthopaedic surgery performed on other parts of the body. However, disparate and inconsistent evidence makes it difficult to draw meaningful conclusions from individual studies.

QUESTIONS/PURPOSES

In this systematic review, we asked: what are (1) the patterns of opioid use or prescription (quantity, duration, incidence of persistent use), (2) factors associated with increased or decreased risk of persistent opioid use, and (3) the clinical outcomes (principally pain relief and adverse events) associated with opioid use in patients undergoing foot or ankle fracture surgery?

METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for our review. We searched PubMed, Embase, Scopus, Cochrane, and Web of Science on October 15, 2021. We included studies published from 2010 to 2021 that assessed patterns of opioid use, factors associated with increased or decreased opioid use, and other outcomes associated with opioid use after foot or ankle fracture surgery (principally pain relief and adverse events). We excluded studies on pediatric populations and studies focused on acute postoperative pain where short-term opioid use (< 1 week) was a secondary outcome only. A total of 1713 articles were assessed and 18 were included. The quality of the 16 included retrospective observational studies and two randomized trials was evaluated using the Methodological Index for Non-Randomized Studies criteria and the Jadad scale, respectively; study quality was determined to be low to moderate for observational studies and good for randomized trials. Mean patient age ranged from 42 to 53 years. Fractures studied included unimalleolar, bimalleolar, trimalleolar, and pilon fractures.

RESULTS

Proportions of postoperative persistent opioid use (defined as use beyond 3 or 6 months postoperatively) ranged from 2.6% (546 of 20,992) to 18.5% (32 of 173) and reached 39% (28 of 72) when including patients with prior opioid use. Among the numerous associations reported by observational studies, two or more preoperative opioid prescriptions had the strongest overall association with increased opioid use, but this was assessed by only one study (OR 11.92 [95% confidence interval (CI) 9.16 to 13.30]; p < 0.001). Meanwhile, spinal and regional anesthesia (-13.5 to -41.1 oral morphine equivalents (OME) difference; all p < 0.01) and postoperative ketorolac use (40 OME difference; p = 0.037) were associated with decreased opioid consumption in two observational studies and a randomized trial, respectively. Three observational studies found that opioid use preoperatively was associated with a higher proportion of emergency department visits and readmission (OR 1.41 to 17.4; all p < 0.001), and opioid use at 2 weeks postoperatively was associated with slightly higher pain scores compared with nonopioid regimens (β = 0.042; p < 0.001 and Likert scale 2.5 versus 1.6; p < 0.05) in one study.

CONCLUSION

Even after noting possible inflation of the harms of opioids in this review, our findings nonetheless highlight the need for opioid prescription guidelines specific for foot and ankle surgery. In this context, surgeons should utilize short (< 1 week) opioid prescriptions, regional anesthesia, and multimodal pain management techniques, especially in patients at increased risk of prolonged opioid use.

Fluctuation of visual analog scale pain scores and opioid consumption before and after total hip arthroplasty

BACKGROUND

Patients who undergo orthopedic procedures are often given excess opioid medication. Understanding the relationship between pain and opioid consumption following total hip arthroplasty (THA) is key to creating safe and effective opioid prescribing guidelines.

AIM

To evaluate the association between the quantity of opioid consumption in relation to pain scores both pre-and postoperatively in patients undergoing primary THA.

METHODS

We retrospectively reviewed patients who underwent primary THA from November 2018-May 2019 and answered both the visual analog scale (VAS) pain and opioid medication questionnaires pre-and postoperatively. Both surveys were delivered daily for 7-days before surgery through the first 30 postoperative days. Survey results were divided into preoperative, postoperative days 1-7, postoperative days 8-14, and postoperative days 15-30 for analysis. Mean opioid pill consumption and VAS pain scores in each time period were determined and compared to patients’ preoperative status using hierarchical Poisson and linear regressions, respectively.

RESULTS

There were 105 patients included. Mean VAS pain scores were the highest preoperatively 7.41 ± 1.72. However, VAS pain scores significantly declined in each successive postoperative category compared to preoperative scores: postoperative day 1-7 (5.07 ± 1.79; P < 0.001), postoperative day 8-14 (3.60 ± 1.64; P < 0.001), and postoperative day 15-30 (3.15 ± 1.63; P < 0.001). Mean opioid pill consumption preoperatively was 0.68 ± 1.29 pills. Compared to preoperative opioid consumption, opioid use was significantly greater between postoperative days 1-7 (1.51 ± 1.58; P = 0.001) and postoperative days 8-14 (1.00 ± 1.27; P = 0.043). Opioid consumption declined below preoperative levels between postoperative days 15-30 (0.35 ± 0.72; P = 0.160) which correlates with a VAS pain score of 3.15.

CONCLUSION

All patients experienced significant benefit and pain relief from having undergone THA. Average postoperative opioid consumption decreased below preoperative consumption between postoperative days 15-30, which was associated with a VAS pain score of 3.15. These results can be used to appropriately guide opioid prescribing practices and set patient expectations regarding pain management following THA.

Standardizing Opioid Prescribing in a Pediatric Hospital: A Quality Improvement Effort

BACKGROUND

Opioids are indicated for moderate-to-severe pain caused by trauma, ischemia, surgery, cancer and sickle cell disease, and vaso-occlusive episodes (SCD-VOC). There is only limited evidence regarding the appropriate number of doses to prescribe for specific indications. Therefore, we developed and implemented an opioid prescribing algorithm with dosing guidelines for specific procedures and conditions. We aimed to reach and sustain 90% compliance within 1 year of implementation.

METHODS

We conducted this quality improvement effort at a pediatric academic quaternary care institution. In 2018, a multidisciplinary team identified the need for a standard approach to opioid prescribing. The algorithm guides prescribers to evaluate the medical history, physical examination, red flags, pain type, and to initiate opioid-sparing interventions before prescribing opioids. Opioid prescriptions written between January 2015 and September 2020 were included. Examples from 2 hospital departments will be highlighted. Control charts for compliance with guidelines and variability in the doses prescribed are presented for selected procedures and conditions.

RESULTS

Over 5 years, 83 037 opioid prescriptions in 53 804 unique patients were entered electronically. The encounters with ≥1 opioid prescription decreased from 48% to 25% between 2015 and 2019. Compliance with the specific guidelines increased to ∼85% for periacetabular osteotomies and SCD-VOC and close to 100% for anterior-cruciate ligament surgery. In all 3 procedures and conditions, variability in the number of doses prescribed decreased significantly.

CONCLUSION

We developed an algorithm, guidelines, and a process for improvement. The number of opioid prescriptions and variability in opioid prescribing decreased. Future evaluation of specific initiatives within departments is needed.
