Abstract
BACKGROUND AND OBJECTIVES METHODS: A structured search strategy encompassing databases including MEDLINE, Embase, CINAHL Plus, PsycINFO and Cochrane Library was implemented from inception to October 2023. Included studies focused on interventions targeting opioid reduction in adults following major surgeries. The risk of bias was evaluated using Cochrane risk-of-bias tool V.2 (RoB 2) and non-randomised studies of interventions (ROBINS-I) tools, and Cohen's d effect sizes were calculated. BCTs were identified using a validated taxonomy. RESULTS 22 studies, comprising 7 clinical trials and 15 cohort studies, were included, with varying risks of bias. Educational (n=12), guideline-focused (n=3), multifaceted (n=5) and pharmacist-led (n=2) interventions demonstrated diverse effect sizes (small-medium n=10, large n=12). A total of 23 unique BCTs were identified across studies, occurring 140 times. No significant association was observed between the number of BCTs and effect size, and interventions with large effect sizes predominantly targeted healthcare professionals. Key BCTs in interventions with the largest effect sizes included behaviour instructions, behaviour substitution, goal setting (outcome), social support (practical), social support (unspecified), pharmacological support, prompts/cues, feedback on behaviour, environmental modification, graded tasks, outcome goal review, health consequences information, action planning, social comparison, credible source, outcome feedback and social reward. CONCLUSIONS Understanding the dominant BCTs in highly effective interventions provides valuable insights for future opioid tapering strategy implementations. Further research and validation are necessary to establish associations between BCTs and effectiveness, considering additional influencing factors. PROSPERO REGISTRATION NUMBER CRD42022290060.

Effectiveness of de-implementation of low-value healthcare practices: an overview of systematic reviews. Implement Sci 2024; 19:56. [PMID: 39103927 DOI: 10.1186/s13012-024-01384-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 07/12/2024] [Indexed: 08/07/2024] Open
Abstract
BACKGROUND Reducing low-value care (LVC) is crucial to improve the quality of patient care while increasing the efficient use of scarce healthcare resources. Recently, strategies to de-implement LVC have been mapped against the Expert Recommendation for Implementing Change (ERIC) compilation of strategies. However, such strategies' effectiveness across different healthcare practices has not been addressed. This overview of systematic reviews aimed to investigate the effectiveness of de-implementation initiatives and specific ERIC strategy clusters. METHODS We searched MEDLINE (Ovid), Epistemonikos.org and Scopus (Elsevier) from 1 January 2010 to 17 April 2023 and used additional search strategies to identify relevant systematic reviews (SRs). Two reviewers independently screened abstracts and full texts against a priori-defined criteria, assessed the SR quality and extracted pre-specified data. We created harvest plots to display the results. RESULTS Of 46 included SRs, 27 focused on drug treatments, such as antibiotics or opioids, twelve on laboratory tests or diagnostic imaging and seven on other healthcare practices. In categorising de-implementation strategies, SR authors applied different techniques: creating self-developed strategies (n = 12), focussing on specific de-implementation strategies (n = 14) and using published taxonomies (n = 12). Overall, 15 SRs provided evidence for the effectiveness of de-implementation interventions to reduce antibiotic and opioid utilisation. Reduced utilisation, albeit inconsistently significant, was documented in the use of antipsychotics and benzodiazepines, as well as in laboratory tests and diagnostic imaging. Strategies within the adapt and tailor to context, develop stakeholder interrelationships, and change infrastructure and workflow ERIC clusters led to a consistent reduction in LVC practices. CONCLUSION De-implementation initiatives were effective in reducing medication usage, and inconsistent significant reductions were observed for LVC laboratory tests and imaging. Notably, de-implementation clusters such as change infrastructure and workflow and develop stakeholder interrelationships emerged as the most encouraging avenues. Additionally, we provided suggestions to enhance SR quality, emphasising adherence to guidelines for synthesising complex interventions, prioritising appropriateness of care outcomes, documenting the development process of de-implementation initiatives and ensuring consistent reporting of applied de-implementation strategies.

Learning from the implementation of a surgical opioid reduction initiative in an integrated health system: a qualitative study among providers and patients. Implement Sci Commun 2024; 5:22. [PMID: 38468284 PMCID: PMC10926556 DOI: 10.1186/s43058-024-00561-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 02/23/2024] [Indexed: 03/13/2024] Open
Abstract
BACKGROUND Surgical opioid overprescribing can result in long-term use or misuse. Between July 2018 and March 2019, the multicomponent intervention, Minimizing Opioid Prescribing in Surgery (MOPiS) was implemented in the general surgery clinics of five hospitals and successfully reduced opioid prescribing. To date, various studies have shown a positive outcome of similar reduction initiatives. However, in addition to evaluating the impact on clinical outcomes, it is important to understand the implementation process of an intervention to extend sustainability of interventions and allow for dissemination of the intervention into other contexts. This study aims to evaluate the contextual factors impacting intervention implementation. METHODS We conducted a qualitative study with semi-structured interviews held with providers and patients of the general surgery clinics of five hospitals of a single health system between March and November of 2019. Interview questions focused on how contextual factors affected implementation of the intervention. We coded interview transcripts deductively, using the Consolidated Framework for Implementation Research (CFIR) to identify the relevant contextual factors. Content analyses were conducted using a constant comparative approach to identify overarching themes. RESULTS We interviewed 15 clinicians (e.g., surgeons, nurses), 1 quality representative, 1 scheduler, and 28 adult patients and identified 3 key themes. First, we found high variability in the responses of clinicians and patients to the intervention. There was a strong need for intervention components to be locally adaptable, particularly for the format and content of the patient and clinician education materials. Second, surgical pain management should be recognized as a team effort. We identified specific gaps in the engagement of team members, including nurses. We also found that the hierarchical relationships between surgical residents and attendings impacted implementation. Finally, we found that established patient and clinician views on opioid prescribing were an important facilitator to effective implementation. CONCLUSION Successful implementation of a complex set of opioid reduction interventions in surgery requires locally adaptable elements of the intervention, a team-centric approach, and an understanding of patient and clinician views regarding changes being proposed.

Abstract
Importance Excess opioid prescribing after surgery can result in prolonged use and diversion. Email feedback based on social norms may reduce the number of pills prescribed. Objective To assess the effectiveness of 2 social norm-based interventions on reducing guideline-discordant opioid prescribing after surgery. Design, Setting, and Participants This cluster randomized clinical trial conducted at a large health care delivery system in northern California between October 2021 and October 2022 included general, obstetric/gynecologic, and orthopedic surgeons with patients aged 18 years or older discharged to home with an oral opioid prescription. Interventions In 19 hospitals, 3 surgical specialties (general, orthopedic, and obstetric/gynecologic) were randomly assigned to a control group or 1 of 2 interventions. The guidelines intervention provided email feedback to surgeons on opioid prescribing relative to institutionally endorsed guidelines; the peer comparison intervention provided email feedback on opioid prescribing relative to that of peer surgeons. Emails were sent to surgeons with at least 2 guideline-discordant prescriptions in the previous month. The control group had no intervention. Main Outcome and Measures The probability that a discharged patient was prescribed a quantity of opioids above the guideline for the respective procedure during the 12 intervention months. Results There were 38 235 patients discharged from 640 surgeons during the 12-month intervention period. Control-group surgeons prescribed above guidelines 36.8% of the time during the intervention period compared with 27.5% and 25.4% among surgeons in the peer comparison and guidelines arms, respectively. In adjusted models, the peer comparison intervention reduced guideline-discordant prescribing by 5.8 percentage points (95% CI, -10.5 to -1.1; P = .03) and the guidelines intervention reduced it by 4.7 percentage points (95% CI, -9.4 to -0.1; P = .05). Effects were driven by surgeons who performed more surgeries and had more guideline-discordant prescribing at baseline. There was no significant difference between interventions. Conclusions and Relevance In this cluster randomized clinical trial, email feedback based on either guidelines or peer comparison reduced opioid prescribing after surgery. Guideline-based feedback was as effective as peer comparison-based feedback. These interventions are simple, low-cost, and scalable, and may reduce downstream opioid misuse.

Abstract
Background and Objectives Opioid overprescribing in patients undergoing breast surgery is a concern, as evidence suggests that minimal or no opioid is needed to manage pain. We sought to describe characteristics of opioid prescribers and determine associations between prescriber's characteristics and high opioid prescribing within 7 days of same-day breast surgery. Methods Patients ≥18 years of age who underwent same-day breast surgery in Ontario, Canada from 2012 to 2020 were identified and linked to prescriber data. The primary outcome was current high opioid prescribing defined as >75th percentile of the mean oral morphine equivalents (OME; milligrams). Prescriber characteristics including age, sex, specialty, years in practice, practice setting, and history of high (>75th percentile) opioid prescribing in the previous year were captured. Associations between prescriber characteristics and the primary outcome were estimated in modified Poisson regression models. Results The final cohort contained 56,434 patients, 3469 unique prescribers, and 58,656 prescriptions. Over half (1971/3469; 57%) of prescribers wrote ≥1 prescription that was >75th percentile of mean OME of 180 mg, of which 50% were family practice physicians. Adjusted mean OMEs prescribed varied by specialty with family practice specialties prescribing the highest mean OME (614 ± 38 mg) compared to surgical specialties (general surgery [165 ± 9 mg], plastic surgery [198 ± 10 mg], surgical oncology [154 ± 14 mg]). Whereas 73% of first and 31% of second prescriptions were provided by general surgery physicians, family practice physicians provided 2% of first and 51% of second prescriptions. Prescriber characteristics associated with a higher likelihood of high current opioid prescribing were family practice (risk ratio [RR], 1.56; 95% confidence interval [CI], 1.35-1.79 compared to general surgery), larger community practice setting (RR, 1.34; 95% CI, 1.05-1.71 compared to urban), and a previous high opioid prescribing behavior (RR, 2.28; 95% CI, 2.06-2.52). Conclusions While most studies examine surgeon opioid prescribing, our data suggest that other specialties contribute to opioid overprescribing in surgical patients and identify characteristics of physicians likely to overprescribe.

Abstract
BACKGROUND Postoperative pain management practices in breast surgery are variable, with recent evidence that approaches for minimizing or sparing opioids can be successfully implemented. We describe opioid filling and predictors of higher doses in patients undergoing same-day breast surgery in Ontario, Canada. METHODS In this retrospective population-based cohort study, we used linked administrative health data to identify patients aged 18 years or older who underwent same-day breast surgery from 2012 to 2020. We categorized procedure types by increasing invasiveness of surgery: partial, with or without axillary intervention (P ± axilla); total, with or without axillary intervention (T ± axilla); radical, with or without axillary intervention (R ± axilla); and bilateral. The primary outcome was filling an opioid prescription within 7 or fewer days after surgery. Secondary outcomes were total oral morphine equivalents (OMEs) filled (mg, median and interquartile range [IQR]) and filling more than 1 prescription within 7 or fewer days after surgery. We estimated associations (adjusted risk ratios [RRs] and 95% confidence intervals [CIs]) between study variables and outcomes in multivariable models. We used a random intercept for each unique prescriber to account for provider-level clustering. RESULTS Of the 84 369 patients who underwent same-day breast surgery, 72% (n = 60 620) filled an opioid prescription. Median OMEs filled increased with invasiveness (P ± axilla = 135 [IQR 90-180] mg; T ± axilla = 135 [IQR 100-200] mg; R ± axilla = 150 [IQR 113-225] mg, bilateral surgery = 150 [IQR 113-225] mg; p < 0.0001). Factors associated with filling more than 1 opioid prescription were age 30-59 years (v. age 18-29 yr), increased invasiveness (RR 1.98, 95% CI 1.70-2.30 bilateral v. P ± axilla), Charlson Comorbidity Index ≥ 2 versus 0-1 (RR 1.50, 95% CI 1.34-1.69) and malignancy (RR 1.39, 95% CI 1.26-1.53). INTERPRETATION Most patients undergoing same-day breast surgery fill an opioid prescription within 7 days. Efforts are needed to identify patient groups where opioids may be successfully minimized or eliminated.

Abstract
INTRODUCTION As deaths related to opioids continue to rise, reducing opioid use for postpartum pain management is an important priority. Thus, we conducted a systematic review of postpartum interventions aimed at reducing opioid use following birth. METHODS From database inception through September 1, 2021, we conducted a systematic search in Embase, MEDLINE, Cochrane Library, and Scopus including the following Medical Subject Heading (MeSH) terms: postpartum, pain management, opioid prescribing. Studies published in English, restricted to the United States, and evaluating interventions initiated following birth with outcomes including an assessment of change in opioid prescribing or use during the postpartum period (<8 weeks postpartum) were included. Authors independently screened abstracts and full articles for inclusion, extracted data, and assessed study quality using the Grading of Recommendations, Assessment, Development, and Evaluation tool and risk of bias using the Institutes of Health Quality Assessment Tools. RESULTS A total of 24 studies met inclusion criteria. Sixteen studies evaluated interventions aimed at reducing postpartum opioid use during the inpatient hospitalization, and 10 studies evaluated interventions aimed at reducing opioid prescribing at postpartum discharge. Inpatient interventions included changes to standard order sets and protocols for the management of pain after cesarean birth. Such interventions resulted in significant decreases in inpatient postpartum opioid use in all but one study. Additional inpatient interventions, including use of lidocaine patches, postoperative abdominal binder, valdecoxib, and acupuncture were not found to be effective in reducing postpartum opioid use during inpatient hospitalization. Interventions targeting the postpartum period included individualized prescribing and state legislative changes limiting the duration of opioid prescribing for acute pain both resulted in decreased opioid prescribing or opioid use. DISCUSSION A variety of interventions aimed at reducing opioid use following birth have shown efficacy. Although it is not known if any single intervention is most effective, these data suggest that implementation of any number of interventions may be advantageous in reducing postpartum opioid use.

Abstract
BACKGROUND The objective was to assess changes over time in prescriptions filled for nonopioid analgesics for older postoperative patients in the immediate postdischarge period. The authors hypothesized that the number of patients who filled a nonopioid analgesic prescription increased during the study period. METHODS The authors performed a population-based cohort study using linked health administrative data of 278,366 admissions aged 66 yr or older undergoing surgery between fiscal year 2013 and 2019 in Ontario, Canada. The primary outcome was the percentage of patients with new filled prescriptions for nonopioid analgesics within 7 days of discharge, and the secondary outcome was the analgesic class. The authors assessed whether patients filled prescriptions for a nonopioid only, an opioid only, both opioid and nonopioid prescriptions, or a combination opioid/nonopioid. RESULTS Overall, 22% (n = 60,181) of patients filled no opioid prescription, 2% (n = 5,534) filled a nonopioid only, 21% (n = 59,608) filled an opioid only, and 55% (n = 153,043) filled some combination of opioid and nonopioid. The percentage of patients who filled a nonopioid prescription within 7 days postoperatively increased from 9% (n = 2,119) in 2013 to 28% (n = 13,090) in 2019, with the greatest increase for acetaminophen: 3% (n = 701) to 20% (n = 9,559). The percentage of patients who filled a combination analgesic prescription decreased from 53% (n = 12,939) in 2013 to 28% (n = 13,453) in 2019. However, the percentage who filled both an opioid and nonopioid prescription increased: 4% (n = 938) to 21% (n = 9,880) so that the overall percentage of patients who received both an opioid and a nonopioid remained constant over time 76% (n = 18,642) in 2013 to 75% (n = 35,391) in 2019. CONCLUSIONS The proportion of postoperative patients who fill prescriptions for nonopioid analgesics has increased. However, rather than a move to use of nonopioids alone for analgesia, this represents a shift away from combination medications toward separate prescriptions for opioids and nonopioids.

Abstract
INTRODUCTION Surgical patients are commonly prescribed more opioids at discharge than needed to manage their postoperative pain. These excess opioids increase the risks of new persistent opioid use, opioid-induced ventilatory impairment and opioid diversion. This study tests the effectiveness of two behavioural nudges, one based on peer behaviour and one based on best practice guidelines, in reducing excessive postoperative opioid prescriptions. METHODS AND ANALYSIS The study will be conducted at 19 hospitals within a large healthcare delivery system in northern California, USA. Three surgical specialties (general surgery, orthopaedic surgery and obstetric/gynaecological surgery) at each hospital will be randomised either to a control group or to one of two active intervention arms. One intervention is grounded in the theory of injunctive norms, and provides feedback to surgeons on their postoperative opioid prescribing relative to prescribing guidelines endorsed by their institution. The other intervention draws from the theory of descriptive norms, and provides feedback similar to the first intervention but using peers' behaviour rather than guidelines as the benchmark for the surgeon's prescribing behaviour. The interventions will be delivered by a monthly email. Both interventions will be active for twelve months. The effects of each intervention relative to the control group and to each other will be tested using a four-level hierarchical model adjusted for multiple hypothesis testing. ETHICS AND DISSEMINATION Using behavioural nudges rather than rigid policy changes allows us to target excessive prescribing without preventing clinicians from using their clinical judgement to address patient pain. All study activities have been approved by the RAND Human Subjects Protection Committee (ID 2018-0988). Findings will be disseminated through conference presentations, peer-reviewed publications and social media accounts. TRIAL REGISTRATION NUMBER NCT05070338.

Abstract
Importance Limiting opioid overprescribing in the emergency department (ED) may be associated with decreases in diversion and misuse. Objective To review and analyze interventions designed to reduce the rate of opioid prescriptions or the quantity prescribed for pain in adults discharged from the ED. Data Sources MEDLINE, Embase, CINAHL, PsycINFO, and Cochrane Controlled Register of Trials databases and the gray literature were searched from inception to May 15, 2020, with an updated search performed March 6, 2021. Study Selection Intervention studies aimed at reducing opioid prescribing at ED discharge were first screened using titles and abstracts. The full text of the remaining citations was then evaluated against inclusion and exclusion criteria by 2 independent reviewers. Data Extraction and Synthesis Data were extracted independently by 2 reviewers who also assessed the risk of bias. Authors were contacted for missing data. The main meta-analysis was accompanied by intervention category subgroup analyses. All meta-analyses used random-effects models, and heterogeneity was quantified using I2 values. Main Outcomes and Measures The primary outcome was the variation in opioid prescription rate and/or prescribed quantity associated with the interventions. Effect sizes were computed separately for interrupted time series (ITS) studies. Results Sixty-three unique studies were included in the review, and 45 studies had sufficient data to be included in the meta-analysis. A statistically significant reduction in the opioid prescription rate was observed for both ITS (6-month step change, -22.61%; 95% CI, -30.70% to -14.52%) and other (odds ratio, 0.56; 95% CI, 0.45-0.70) study designs. No statistically significant reduction in prescribed opioid quantities was observed for ITS studies (6-month step change, -8.64%; 95% CI, -17.48% to 0.20%), but a small, statistically significant reduction was observed for other study designs (standardized mean difference, -0.30; 95% CI, -0.51 to -0.09). For ITS studies, education, policies, and guideline interventions (6-month step change, -33.31%; 95% CI, -39.67% to -26.94%) were better at reducing the opioid prescription rate compared with prescription drug monitoring programs and laws (6-month step change, -11.18%; 95% CI, -22.34% to -0.03%). Most intervention categories did not reduce prescribed opioid quantities. Insufficient data were available on patient-centered outcomes such as pain relief or patients' satisfaction. Conclusions and Relevance This systematic review and meta-analysis found that most interventions reduced the opioid prescription rate but not the prescribed opioid quantity for ED-discharged patients. More studies on patient-centered outcomes and using novel approaches to reduce the opioid quantity per prescription are needed. Trial Registration PROSPERO Identifier: CRD42020187251.

Abstract
While U.S. opioid prescribing has decreased 38% in the past decade, opioid deaths have increased 300%. This opioid paradox is poorly recognized. Current approaches to opioid management are not working, and new approaches are needed. This article reviews the outcomes and shortcomings of recent U.S. opioid policies and strategies that focus primarily or exclusively on reducing or eliminating opioid prescribing. It introduces concepts of a prescription opioid ecosystem and opioid pool, and it discusses how the pool can be influenced by supply-side, demand-side, and opioid returns factors. It illuminates pressing policy needs for an opioid ecosystem that enables proper opioid stewardship, identifies associated responsibilities, and emphasizes the necessity of making opioid returns as easy and common as opioid prescribing, in order to minimize the size of the opioid pool available for potential diversion, misuse, overdose, and death. Approaches are applicable to opioid prescribing in general, and to opioid prescribing after surgery.

Institutional Opioid Prescription Guidelines are Effective in Reducing Post-Operative Prescriptions Following Urologic Surgery: Results From the American Urologic Association 2018 Census. Urology 2021; 158:5-10.

Abstract
OBJECTIVE To assess provider and practice characteristics that drive opioid prescription behavior using the American Urological Association census data. METHODS Stratified weighted analysis using 1,157 census samples was performed to represent 12,660 urologists who practiced in the United States in 2018. We compared urologists according to their opioid prescription patterns to evaluate factors and motivations behind opioid use in the post-operative setting. RESULTS Overall, 11,205 (88.5%) urologists prescribe opioids in the post-operative setting. The presence of procedure-specific institutional prescribing guidelines was associated with a greater tendency to prescribe ≤10 pills, and lesser tendency to prescribe 11 to 49 and ≥50 tablets following open abdominal (P = .003), laparoscopic (P < .001), scrotal (P < .001), and endoscopic surgeries (P < .001). The presence of institutional prescribing guidelines was associated with decreasing opioid prescriptions over a three-year period whereas not having guidelines was associated with an unchanged prescription practice over time. Basing current prescriptions on what was given to prior patients was reported by 85% and was more likely to result in an unchanged amount of prescriptions over time (29.2% vs 13.3%, P = .007). Motivations to avoid patient phone calls were reported by 23.8% and were more likely to increase the opioids provided within the next 3 years (3.2% vs 0.1%, P < .001). CONCLUSION Practitioners who endorsed using institutional guidelines prescribed fewer opioids following all types of surgery and were more likely to decrease their prescription behavior over time. This data supports continued efforts to provide urologists with more evidence-based guidance on best practice opioid prescribing in the future.

Abstract
PURPOSE Canadian seniors who undergo hip and knee arthroplasty often experience significant postoperative pain, which could result in persistent opioid use. We aimed to document the impact of preoperative opioid use and other characteristics on postoperative opioid prescriptions in elderly patients following hip and knee replacement before widespread dissemination of opioid reduction strategies. METHODS We conducted a historical cohort study to evaluate postoperative opioid use in patients over 65 yr undergoing primary total hip and knee replacement over a ten-year period from 1 April 2006 to 31 March 2016, using linked de-identified Ontario administrative data. We determined the use of preoperative opioids and the duration of postoperative opioid prescriptions (short-term [1-90 days], prolonged [91-180 days], chronic [181-365 days], or undocumented). RESULTS The study included 49,638 hip and 85,558 knee replacement patients. Eighteen percent of hip and 21% of knee replacement patients received an opioid prescription within 90 days before surgery. Postoperatively, 51% of patients filled opioid prescriptions for 1-90 days, while 24% of hip and 29% of knee replacement patients filled prescriptions between 6 and 12 months, with no impact of preoperative opioid use. Residence in long-term care was a significant predictor of chronic opioid use (hip: odds ratio [OR], 2.64; 95% confidence interval [CI], 1.93 to 3.59; knee: OR, 2.46; 95% CI, 1.75 to 3.45); other risk factors included female sex and increased comorbidities. CONCLUSION Despite a main goal of joint arthroplasty being relief of pain, seniors commonly remained on postoperative opioids, even if not receiving opioids before surgery. Opioid reduction strategies need to be implemented at the surgical, primary physician, long-term care, and patient levels. These findings form a basis for future investigations following implementation of opioid reduction approaches.

Abstract
Prescription opioid use has risen steeply for over two decades, driven primarily by advocacy for better management of chronic non-cancer pain, but also by poor opioid stewardship in the management of acute pain. Inappropriate prescribing, among other things, contributed to the opioid 'epidemic' and striking increases in patient harm. It has also seen a greater proportion of opioid-tolerant patients presenting to acute care hospitals. Effective and safe management of acute pain in opioid-tolerant patients can be challenging, with higher risks of opioid-induced ventilatory impairment and persistent post-discharge opioid use compared with opioid-naive patients. There are also increased risks of some less well known adverse postoperative outcomes including infection, earlier revision rates after major joint arthroplasty and spinal fusion, longer hospital stays, higher re-admission rates and increased healthcare costs. Increasingly, opioid-free/opioid-sparing techniques have been advocated as ways to reduce patient harm. However, good evidence for these remains lacking and opioids will continue to play an important role in the management of acute pain in many patients.Better opioid stewardship with consideration of preoperative opioid weaning in some patients, assessment of patient function rather than relying on pain scores alone to assess adequacy of analgesia, prescription of immediate release opioids only and evidence-based use of analgesic adjuvants are important. Post-discharge opioid prescribing should be contingent on an assessment of patient risk, with short-term only use of opioids. In partnership with pharmacists, nursing staff, other medical specialists, general practitioners and patients, anaesthetists remain ideally positioned to be involved in opioid stewardship in the acute care setting.

Abstract
BACKGROUND The purpose of this comprehensive review was to investigate risk factors associated with prolonged opioid use after orthopaedic procedures. A comprehensive review of the opioid literature may help to better guide preoperative management of expectations as well as opioid-prescribing practices. METHODS A systematic review of all studies pertaining to opioid use in relation to orthopaedic procedures was conducted using the MEDLINE, Embase, and CINAHL databases. Data from studies reporting on postoperative opioid use at various time points were collected. Opioid use and risk of prolonged opioid use were subcategorized by subspecialty, and aggregate data for each category were calculated. RESULTS There were a total of 1,445 eligible studies, of which 45 met inclusion criteria. Subspecialties included joint arthroplasty, spine, trauma, sports, and hand surgery. A total of 458,993 patients were included, including 353,330 (77%) prolonged postoperative opioid users and 105,663 (23%) non-opioid users. Factors associated with prolonged postoperative opioid use among all evaluated studies included body mass index (BMI) of ≥40 kg/m (relative risk [RR], 1.06 to 2.32), prior substance abuse (RR, 1.08 to 3.59), prior use of other medications (RR, 1.01 to 1.46), psychiatric comorbidities (RR, 1.08 to 1.54), and chronic pain conditions including chronic back pain (RR, 1.01 to 10.90), fibromyalgia (RR, 1.01 to 2.30), and migraines (RR, 1.01 to 5.11). Age cohorts associated with a decreased risk of prolonged postoperative opioid use were those ≥31 years of age for hand procedures (RR, 0.47 to 0.94), ≥50 years of age for total hip arthroplasty (RR, 0.70 to 0.80), and ≥70 years of age for total knee arthroplasty (RR, 0.40 to 0.80). Age cohorts associated with an increased risk of prolonged postoperative opioid use were those ≥50 years of age for sports procedures (RR, 1.11 to 2.57) or total shoulder arthroplasty (RR, 1.26 to 1.40) and those ≥70 years of age for spine procedures (RR, 1.61). Identified risk factors for postoperative use were similar across subspecialties. CONCLUSIONS We provide a comprehensive review of the various preoperative and postoperative risk factors associated with prolonged opioid use after elective and nonelective orthopaedic procedures. Increased BMI, prior substance abuse, psychiatric comorbidities, and chronic pain conditions were most commonly associated with prolonged postoperative opioid use. Careful consideration of elective surgical intervention for painful conditions and perioperative identification of risk factors within each patient's biopsychosocial context will be essential for future modulation of physician opioid-prescribing patterns.

Abstract
BACKGROUND Opioids are the most commonly prescribed analgesics in the United States. Current guidelines have proposed education initiatives to reduce the risk of chronic opioid consumption, yet there is lack of efficacy data on such interventions. Our study evaluates the impact of perioperative opioid education on postoperative opioid consumption patterns including opioid cessation, number of pills consumed, and opioid prescription refills. METHODS The MEDLINE/PubMed, Embase, Cochrane Library, Scopus, and Google Scholar databases were systematically searched for randomized controlled trials (RCTs) assessing the impact of perioperative educational interventions (using either paper- or video-based instruments regarding pain management and drug-induced side effects) on postoperative opioid patterns compared to standard preoperative care among patients undergoing elective surgery. Our end points were opioid consumption (number of pills used), appropriate disposal of unused opioids, opioid cessation (defined as no use of opioids), and opioid refills within 15 days, 6 weeks, and 3 months. RESULTS In total, 11 RCTs fulfilled the inclusion criteria, totaling 1604 patients (804 received opioid education, while 800 received standard care). Six trials followed patients for 15 days after surgery, and 5 trials followed patients up to 3 months. After 15 days, the opioid education group consumed a lower number of opioid pills than those in the control group (weighted mean difference [WMD], -3.39 pills; 95% confidence interval [CI], -6.40 to -0.37; P =.03; I2 = 69%) with no significant difference in overall opioid cessation (odds ratio [OR], 0.25; 95% CI, 0.04-1.56; P = .14; I2 = 83%). Likewise, perioperative opioid education did not have significant effects on opioid cessation at 6 weeks (OR, 0.69; 95% CI, 0.45-1.05; P = .10; I2 = 0%) and 3 months (OR, 0.59; 95% CI,0.17-2.01; P = .10; I2 = 0%) after surgery, neither reduced the need for opioid refills at 15 days (OR, 0.57; 95% CI, 0.28-1.15; P = .12; I2 = 20%) and 6 weeks (OR, 1.08; 95% CI, 0.59-1.98; P = .80; I2 = 37%). There was no statistically significant difference in the rate of appropriate disposal of unused opioids between both groups (OR, 1.99; 95% CI, 0.66-6.00; P = .22; I2 = 71%). Subgroup analysis by type of educational intervention showed a statistical reduction of opioid consumption at 15 days when implementing multimedia/audiovisual strategies (4 trials: WMD, -4.05 pills; 95% CI, -6.59 to -1.50; P = .002; I2 = 45%), but there was no apparent decrease when using only paper-based strategies (2 trials: WMD, -2.31 pills; 95% CI, -12.21 to 7.59; P = .65; I2 = 80%). CONCLUSIONS Perioperative educational interventions reduced the number of opioid pills consumed at 15 days but did not demonstrate a significant effect on opioid cessation or opioid refills at 15 days, 6 weeks, and 3 months. Further randomized trials should focus on evidence-based educational interventions with strict homogeneity of material to draw a more definitive recommendation.

An Interactive Pain Application (MServ) Improves Postoperative Pain Management. Pain Res Manag 2021; 2021:8898170. [PMID: 33868524 PMCID: PMC8035036 DOI: 10.1155/2021/8898170] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 01/25/2021] [Accepted: 03/01/2021] [Indexed: 11/21/2022]
Abstract
Background Most patients have moderate or severe pain after surgery. Opioids are the cornerstone of treating severe pain after surgery but cause problems when continued long after discharge. We investigated the efficacy of multifunction pain management software (MServ) in improving postoperative pain control and reducing opioid prescription at discharge. Methods We recruited 234 patients to a prospective cohort study into sequential groups in a nonrandomised manner, one day after major thoracic or urological surgery. Group 1 received standard care (SC, n = 102), group 2 were given a multifunctional device that fed back to the nursing staff alone (DN, n = 66), and group 3 were given the same device that fed back to both the nursing staff and the acute pain team (DNPT, n = 66). Patient-reported pain scores at 24 and 48 hours and patient-reported time in severe pain, medications, and satisfaction were recorded on trial discharge. Findings. Odds of having poor pain control (>1 on 0–4 pain scale) were calculated between standard care (SC) and device groups (DN and DNPT). Patients with a device were significantly less likely to have poor pain control at 24 hours (OR 0.45, 95% CI 0.25, 0.81) and to report time in severe pain at 48 hours (OR 0.62, 95% CI 0.47–0.80). Patients with a device were three times less likely to be prescribed strong opioids on discharge (OR 0.35, 95% CI 0.13 to 0.95). Interpretation. Using an mHealth device designed for pain management, rather than standard care, reduced the incidence of poor pain control in the postoperative period and reduced opioid prescription on discharge from hospital.

Abstract
PURPOSE OF REVIEW This review aims to summarize interventions used in the perioperative period to reduce the development of new persistent postoperative opioid use in opioid-naïve patients. RECENT FINDINGS The development of new persistent opioid use after surgery has recently been identified as a common postoperative complication. The existing literature suggests that interventions across the continuum of care have been shown to decrease the incidence of new persistent postoperative opioid use. Specific preoperative, intraoperative, and postoperative interventions will be reviewed, as well as the use of clinical pathways and protocols that span throughout the perioperative period. Common to many of these interventions include the use of multimodal analgesia throughout the perioperative period and an emphasis on a patient-centered, evidence-based approach to the perioperative pain management plan. While the incidence of new persistent postoperative opioid use appears to be high, the literature suggests that there are both small- and large-scale interventions that can be used to reduce this. Technological advances including prescription monitoring systems and mobile applications have enabled studies to monitor opioid consumption after discharge. Interventions that occur preoperatively, such as patient education and expectation setting regarding postoperative pain management, and interventions that occur postoperatively, such as the implementation of procedure-specific, evidence-based prescribing guidelines and protocols, have been shown to reduce post-discharge opioid consumption. The use of multimodal analgesia and opioid-sparing adjuncts throughout the perioperative period is central to many of these interventions and has essentially become standard of care for management of perioperative pain.

BMJ Qual Saf 2020; 30:251-259. [PMID: 32938775 DOI: 10.1136/bmjqs-2020-011295] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 08/15/2020] [Accepted: 08/24/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Opioids are prescribed in excess after surgery. We leveraged our continuous quality improvement infrastructure to implement opioid prescribing guidelines and subsequently evaluate changes in postoperative opioid prescribing, consumption and patient satisfaction/pain in a statewide regional health system. METHODS We collected data regarding postoperative prescription size, opioid consumption and patient-reported outcomes from February 2017 to May 2019, from a 70-hospital surgical collaborative. Three iterations of prescribing guidelines were released. An interrupted time series analysis before and after each guideline release was performed. Linear regression was used to identify trends in consumption and patient-reported outcomes over time. RESULTS We included 36 022 patients from 69 hospitals who underwent one of nine procedures in the guidelines, of which 15 174 (37.3%) had complete patient-reported outcomes data following surgery. Before the intervention, prescription size was decreasing over time (slope: -0.7 tablets of 5 mg oxycodone/month, 95% CI -1.0 to -0.5 tablets, p<0.001). After the first guideline release, prescription size declined by -1.4 tablets/month (95% CI -1.8 to -1.0 tablets, p<0.001). The difference between these slopes was significant (p=0.006). The second guideline release resulted in a relative increase in slope (-0.3 tablets/month, 95% CI -0.1 to -0.6, p<0.001). The third guideline release resulted in no change (p=0.563 for the intervention). Overall, mean (SD) prescription size decreased from 25 (17) tablets of 5 mg oxycodone to 12 (8) tablets. Opioid consumption also decreased from 11 (16) to 5 (7) tablets (p<0.001), while satisfaction and postoperative pain remained unchanged. CONCLUSIONS The use of procedure-specific prescribing guidelines reduced statewide postoperative opioid prescribing by 50% while providing satisfactory pain care. These results demonstrate meaningful impact on opioid prescribing using evidence-based best practices and serve as an example of successful utilisation of a regional health collaborative for quality improvement.

Consensus Statement for the Prescription of Pain Medication at Discharge after Elective Adult Surgery. Can J Pain 2020; 4:67-85. [PMID: 33987487 PMCID: PMC7951150 DOI: 10.1080/24740527.2020.1724775] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 01/30/2020] [Accepted: 01/30/2020] [Indexed: 12/12/2022]
Abstract
This Consensus Statement provides recommendations on the prescription of pain medication at discharge from hospital for opioid-naïve adult patients who undergo elective surgery. It encourages health care providers (surgeons, anesthesiologists, nurses/nurse practitioners, pain teams, pharmacists, allied health professionals, and trainees) to (1) use nonopioid therapies and reduce the prescription of opioids so that fewer opioid pills are available for diversion and (2) educate patients and their families/caregivers about pain management options after surgery to optimize quality of care for postoperative pain. These recommendations apply to opioid-naïve adult patients who undergo elective surgery. This consensus statement is intended for use by health care providers involved in the management and care of surgical patients. A modified Delphi process was used to reach consensus on the recommendations. First, the authors conducted a scoping review of the literature to determine current best practices and existing guidelines. From the available literature and expertise of the authors, a draft list of recommendations was created. Second, the authors asked key stakeholders to review and provide feedback on several drafts of the document and attend an in-person consensus meeting. The modified Delphi stakeholder group included surgeons, anesthesiologists, residents, fellows, nurses, pharmacists, and patients. After multiple iterations, the document was deemed complete. The recommendations are not graded because they are mostly based on consensus rather than evidence.
