Spine (Phila Pa 1976) 2024; 49:58-63. [PMID: 37612894 DOI: 10.1097/brs.0000000000004806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Accepted: 08/15/2023] [Indexed: 08/25/2023]
Abstract
STUDY DESIGN Propensity-matched cohort. OBJECTIVE The aim of this study was to determine if opioid-sparing anesthesia (OSA) reduces in-hospital and 1-year postoperative opioid consumption. SUMMARY OF BACKGROUND DATA The recent opioid crisis highlights the need to reduce opioid exposure. We developed an OSA protocol for lumbar spinal fusion surgery to mitigate opioid exposure. MATERIALS AND METHODS Patients undergoing lumbar fusion for degenerative conditions over one to four levels were identified. Patients taking opioids preoperatively were excluded. OSA patients were propensity-matched to non-OSA patients based on age, sex, smoking status, body mass index, American Society of Anesthesiologists grade, and revision versus primary procedure. Standard demographic and surgical data, daily in-hospital opioid consumption, and opioid prescriptions 1 year after surgery were compared. RESULTS Of 296 OSA patients meeting inclusion criteria, 172 were propensity-matched to non-OSA patients. Demographics were similar between cohorts (OSA: 77 males, mean age=57.69 yr; non-OSA: 67 males, mean age=58.94 yr). OSA patients had lower blood loss (326 mL vs. 399 mL, P =0.014), surgical time (201 vs. 233 min, P <0.001) emergence to extubation time (9.1 vs. 14.2 min, P< 0.001), and recovery room time (119 vs. 140 min, P =0.0.012) compared with non-OSA patients. Fewer OSA patients required nonhome discharge (18 vs. 41, P =0.001) compared with the non-OSA cohort, but no difference in length of stay (90.3 vs. 98.5 h, P =0.204). Daily opioid consumption was lower in the OSA versus the non-OSA cohort from postoperative day 2 (223 vs. 185 morphine milligram equivalents, P =0.017) and maintained each day with lower total consumption (293 vs. 225 morphine milligram equivalents, P =0.003) throughout postoperative day 4. The number of patients with active opioid prescriptions at 1, 3, 6, and 12 months postoperative was statistically fewer in the OSA compared with the non-OSA patients. CONCLUSIONS OSA for lumbar spinal fusion surgery decreases in-hospital and 1-year postoperative opioid consumption. The minimal use of opioids may also lead to shorter emergence to extubation times, shorter recovery room stays, and fewer discharges to nonhome facilities.

Abstract
BACKGROUND Persistent opioid use following surgery is common especially in patients with preoperative opioid use. This study aims to determine the long-term effect of an individualised opioid tapering plan versus standard of care in patients with a preoperative opioid use undergoing spine surgery at Aarhus University Hospital, Denmark. METHODS This is the 1-year follow-up of a prospective, single-centre, randomised trial of 110 patients who underwent elective spine surgery for degenerative disease. The intervention was an individualised tapering plan at discharge and telephone counselling 1 week after discharge, compared to standard of care. Postoperative outcomes after 1 year include opioid use, reasons for opioid use and pain intensity. RESULTS The overall response rate to the 1-year follow-up questionnaire was 94% (intervention group 52/55 patients and control group 51/55 patients). Forty-two patients (proportion = 0.81, 95% CI 0.67-0.89) in the intervention group compared to 31 (0.61, 95% CI 0.47-0.73; p = .026) patients in the control group succeeded in tapering to zero 1 year after discharge (p = .026). One patient (0.02, 95% CI 0.01-0.13) in the intervention group compared to seven patients (0.14, 95% CI 0.07-0.26) in the control group were unable to taper to their preoperative dose 1 year after discharge (p = .025). Back/neck and radicular pain intensity was similar between study groups. CONCLUSION These results suggest that an individualised tapering plan at discharge combined with telephone counselling 1 week after discharge can reduce opioid use 1 year after spine surgery.

Abstract
The purpose of this study was to evaluate the impact of opioid-limiting legislation on perioperative opioid prescriptions in total knee arthroplasty. The hypothesis was that opioid legislation has reduced opioid prescription filling above levels anticipated by national trends. This study retrospectively evaluated opioid prescription filling for all patients undergoing total knee arthroplasty in a commercially available insurance database between 2010 and 2018 (n=1,068,764). Initial discharge and 90-day cumulative oxycodone 5-mg equivalents filled were tabulated. Opioid prescription filling was evaluated over time and between states with and without opioid-limiting legislation using analysis of variance and multivariable linear and logistic regression. States with and without opioid legislation had significant reductions in initial and cumulative opioid prescription filling volume (all P<.001). However, the magnitude of this reduction was larger in states with opioid legislation. Legislation targeting duration and volume had the largest impact on initial post-act opioid prescription filling volume compared with states without legislation in an estimated "pre-act" time frame. Legislation targeting duration and volume and no specific target had the largest impact on cumulative post-act opioid prescription filling volume. States without legislation still had large, significant reductions in filling volume, but the magnitude was not as great as in states with opioid legislation. States with and without opioid legislation had significant decreases in initial and cumulative opioid prescription filling volume. However, the magnitude of reduction was larger in states that enacted legislation. Younger age, pre-operative opioid use, and higher comorbidity burden were associated with greater opioid use postoperatively. [Orthopedics. 202x;4x(x):xx-xx.].

Preoperative opioids before adult spinal deformity surgery associated with increased reoperations and high rates of chronic postoperative opioid use at 3-year follow-up. Spine Deform 2022; 10:615-623. [PMID: 35066794 PMCID: PMC9063716 DOI: 10.1007/s43390-021-00450-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Accepted: 11/20/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE To determine the association of preoperative opioid prescriptions with reoperations and postoperative opioid prescriptions after adult spina deformity (ASD) surgery. With the current opioid crisis, patients undergoing surgery for ASD are at particular risk for opioid-related complications due to significant preoperative disability and surgical morbidity. No previous studies consider preoperative opioids in this population. METHODS A retrospective cohort study of patients undergoing posterior spinal fusion (7 or more levels) for ASD was performed. All patients had at least 3 years of postoperative follow-up 3 years postoperatively. Prescriptions for 4 different opioid medications (hydromorphone, oxycodone, hydrocodone, and tramadol) were identified within 3 months preoperatively and up to 3 years postoperatively. Multivariate regression was utilized to determine the association of preoperative use with reoperations and with postoperative opioid use, controlling for both patient and surgery-related confounding factors. RESULTS A total of 743 patients were identified and 59.6% (443) had opioid prescriptions within 3 months preoperatively. Postoperative opioid prescriptions were identified in 66.9% of patients at 12 months postoperatively, and in 54.8% at 36 months postoperatively. The 3-year reoperation rate was 11.0% in patients without preoperative prescriptions, 16.0% in patients with preoperative any opioid prescriptions (P = 0.07), and 34.8% in patients with preoperative hydromorphone prescriptions (P < 0.01). In multivariate analysis, preoperative opioid prescriptions were associated with increased reoperations (odds ratio [OR]: 1.62, P = 0.04), and chronic postoperative opioid use (OR: 4.40, P < 0.01). Preoperative hydromorphone prescriptions had the strongest association with both reoperations (OR: 4.96; P < 0.01) and chronic use (OR: 5.19: P = 0.03). CONCLUSION In the ASD population, preoperative opioids are associated with both reoperations and chronic opioid use, with hydromorphone having the strongest association. Further investigation of the benefits of preoperative weaning programs is warranted.

The Impact of Perioperative Multimodal Pain Management on Postoperative Outcomes in Patients (Aged 75 and Older) Undergoing Short-Segment Lumbar Fusion Surgery. Pain Res Manag 2022; 2022:9052246. [PMID: 35265235 PMCID: PMC8898790 DOI: 10.1155/2022/9052246] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 01/26/2022] [Accepted: 01/31/2022] [Indexed: 11/18/2022]
Abstract
Background Due to the presence of multimorbidity and polypharmacy, patients aged 75 and older are at a higher risk for postoperative adverse events after lumbar fusion surgery. More effective enhanced recovery pathway is needed for these patients. Pain control is a crucial part of perioperative management. The objective of this study is to determine the impact of multimodal pain management on pain control, opioid consumption, and other outcomes. Methods This is a retrospective review of a prospective collected database. Consecutive patients who underwent elective posterior lumbar fusion surgery (PLF) from October 2017 to April 2021 in our hospital were reviewed. Perioperative multimodal pain management (PMPM) group (from January 2019 to April 2021) in which patients received multimodal analgesia was case-matched to the control group (from October 2017 to December 2018) in which patients were treated under the conventional patient-controlled analgesia (PCA) method. Postoperative visual analogue scale (VAS), opioid consumption, complications within 3 months, and other outcomes were collected and compared between groups. Results A total of 122 consecutive patients (aged 75 and older) were included in the PMPM group and compared with previous 122 patients. The PMPM group had a lower maximal VAS score (3.0 ± 1.7 vs. 3.7 ± 2.0, p < 0.001) and frequency of additional opioid consumption (6.6% vs. 19.7%, p=0.001) on POD3 than the control group. The rates of postoperative complications were lower in the PMPM group compared with the control group (25% vs. 49%, p=0.006) during a 3-month follow-up period. Conclusions This study demonstrates that the PMPM protocol is effective in pain control and reducing additional opioid consumption when compared with conventional analgesia, even for patients aged 75 and older. Moreover, these improvements occur with a lower incidence of postoperative complications within three months after PLF surgery.

Abstract
OBJECTIVE To conduct a comprehensive systematic review and meta-analysis of current retrospective cohort studies to identify significant preoperative risk factors for prolonged postoperative opioid use following spine surgery. METHODS Studies were identified according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) through a search of the PubMed, Google Scholar, Scopus, Cochrane databases. Unique articles were screened by two independent reviewers. Primary research articles reporting odds ratios (OR) of risk factors for prolonged opioid use as following spine surgery were included. Prolonged opioid use was defined as continued use ≥ 3 months following surgery, and study quality was evaluated using the Newcastle-Ottawa Scale (NOS). Random effects meta-analysis was performed to calculate pooled OR and confidence intervals. RESULTS 648 studies were returned upon initial search. Following duplicate removal, 492 titles and abstracts were screened. After full-text review of 68 studies, 19 final studies including 168,961 patients were eligible for meta-analysis. NOS scores ranged from 6-9. Seventeen risk factors for long-term opioid use were assessed by meta-analysis. Preoperative opioid use, depression, depression and/or anxiety, drug abuse or dependency, female gender, fibromyalgia, lower back pain, tobacco use, and chronic pulmonary disease were found to be statistically significant risk factors for prolonged opioid use. CONCLUSION These results suggest that several patient-level factors may play a role in the tendency to persistently utilize opioids following spine surgery. By preoperatively identifying these characteristics, clinicians may be better able to identify patients that are at-risk and employ methods to mitigate potential long-term opioid use.

Abstract
STUDY DESIGN Single-center, investigator-initiated, prospective cohort study. OBJECTIVE This study aimed to determine patient-reported reasons for persistent opioid use following elective spine surgery, assess the frequency of withdrawal symptoms, and characterize pain-related care sought after discharge. SUMMARY OF BACKGROUND DATA Patients are often prescribed opioids at discharge from hospital following surgery. Several studies have shown that a large number of patients fail to discontinue opioid treatment and use opioids even months to years after surgery. Spine surgery has proven to be a high-risk procedure in regard to persistent opioid use. There is, however, limited evidence on why patients continue to take opioids. METHODS Three hundred patients, scheduled to undergo spine surgery at Aarhus University Hospital, Denmark, were included. Baseline characteristics and discharge data on opioid consumption were collected. Data on opioid consumption, patient-reported reasons for opioid use, withdrawal symptoms, and pain-related care sought were collected at 3- and 6-month follow-up via a REDCap survey. RESULTS Before surgery, opioid use was reported in 53% of patients. Three months after surgery, opioid use was reported in 60% of preoperative opioid-users and in 9% of preoperative opioid non-users. Patients reported the following reasons for postoperative opioid use: treatment of surgery-related pain (53%), treatment of surgery-related pain combined with other reasons (37%), and reasons not related to spine surgery (10%). Withdrawal symptoms were experienced by 33% of patients during the first 3 months after surgery and were associated with failure to discontinue opioid treatment (P < 0.001). Half of patients (52%) contacted health care after discharge with pain-related topics the first 3 months. CONCLUSION Patients use opioids after spine surgery for reasons other than surgery-related pain. Withdrawal symptoms are frequent even though patients are given tapering plans at discharge. Further studies should address how to facilitate successful and safe opioid tapering in patients undergoing spine surgery.Level of Evidence: 3.

Shared decision-making approach to taper postoperative opioids in spine surgery patients with preoperative opioid use: a randomized controlled trial. Pain 2021; 163:e634-e641. [PMID: 34433772 DOI: 10.1097/j.pain.0000000000002456] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 08/10/2021] [Indexed: 11/26/2022]
Abstract
ABSTRACT Persistent opioid use is common after surgery, and patients with preoperative opioid use represent a major challenge in this regard. The aim of this randomized controlled trial was to determine the effect of a personalized opioid tapering plan vs standard of care in patients with a preoperative opioid use undergoing spine surgery at Aarhus University Hospital, Denmark. Postoperative outcomes included opioid use, pain, contacts with the healthcare system, patient satisfaction, and withdrawal symptoms. Overall, 110 patients were randomized; 55 into the intervention and control groups each. Five patients (proportion = 0.09, 95% confidence interval [CI] [0.04-0.21]) in the intervention group compared with 13 patients (0.25, 95% CI [0.15-0.39]) in the control group were unable to taper opioids to their preoperative consumption 1 month after discharge (P = 0.03) (primary outcome). Likewise, more patients in the intervention group succeeded in tapering opioids to zero 3 months after discharge (37 patients; 0.71, 95% CI [0.57-0.82] vs 23 patients; 0.43, 95% CI [0.30-0.56], P = 0.003). Fewer patients in the intervention group had pain-related contacts to health care the first 2 weeks after discharge (21 patients; 0.40, 95% CI [0.28-0.54] vs 31 patients; 0.60, 95% CI [0.46-0.73], P = 0.04). There was no difference in satisfaction with pain treatment over the first 2 weeks or the incidence of withdrawal symptoms during the first month after discharge. Pain intensity was similar between both groups at all time points. These results suggest that a personalized tapering plan at discharge combined with telephone counselling 1 week after discharge assists patients in postoperative opioid tapering.

Abstract
PURPOSE No reference material exists on the scope of long-term problems in novel spinal pain opioid users. In this study, we evaluate the prevalence and long-term use of prescribed opioids in patients of the Spinal Pain Opioid Cohort. METHODS The setting was an outpatient healthcare entity (Spine Center). Prospective variables include demographics, clinical data collected in SpineData, and The Danish National Prescription Registry. Patients with a new spinal pain episode lasting for more than two months, aged between 18 and 65 years, who had their first outpatient visit. Based on the prescription of opioids from 4 years before the first spine center visit to 5 years after, six or more opioid prescriptions in a single 1-year interval fulfilled the main outcome criteria Long-Term Opioid Therapy (LTOT). RESULTS Overall, of 8356 patients included in the cohort, 4409 (53%) had one or more opioid prescriptions in the registered nine years period. Of opioid users, 2261 (27%) were NaiveStarters receiving their first opioid prescription after a new acute pain episode; 2148(26%) PreStarters had previously received opioids. The prevalence of LTOT in PreStarters/NaiveStarters was 17.2%/11.2% in their first outpatient year. Similar differences between groups were seen in all follow-up intervals. In the last follow-up year, LTOT prevalence in Prestarters/NaiveStarters was 12.5%/7.0%. CONCLUSIONS Previous opioid treatment-i.e., before a new acute spinal pain episode and referral to a Spine Center-doubled the risk of LTOT 5 years later. The results underscore clinicians' obligation to carefully and individually weigh the benefits against the risks of prescribing opioid therapy. LEVEL OF EVIDENCE I Diagnostic: individual cross-sectional studies with consistently applied reference standard and blinding.
