Preoperative Opioid Use as a Predictor of Adverse Postoperative Self-Reported Outcomes in Patients Undergoing Spine Surgery

BACKGROUND Opioids are commonly used for preoperative pain management in patients undergoing spine surgery. The objective of this investigation was to assess whether preoperative opioid use predicts worse self-reported outcomes in patients undergoing spine surgery. METHODS Five hundred and eighty-three patients undergoing lumbar, thoracolumbar, or cervical spine surgery to treat a structural lesion were included in this prospective cohort study. Self-reported preoperative opioid consumption data were obtained at the preoperative visit and were converted to the corresponding daily morphine equivalent amount. Patient-reported outcome measures were assessed at three and twelve months postoperatively via the 12-Item Short-Form Health Survey and the EuroQol-5D questionnaire, as well as, when appropriate, the Oswestry Disability Index and the Neck Disability Index. Separate multivariable linear regression analyses were then performed. RESULTS At the preoperative evaluation, of the 583 patients, 56% (326 patients) reported some degree of opioid use. Multivariable analyses controlling for age, sex, diabetes, smoking, surgery invasiveness, revision surgery, preoperative Modified Somatic Perception Questionnaire score, preoperative Zung Depression Scale score, and baseline outcome score found that increased preoperative opioid use was a significant predictor (p < 0.05) of decreased 12-Item Short-Form Health Survey and EuroQol-5D scores, as well as of increased Oswestry Disability Index and Neck Disability Index scores at three and twelve months postoperatively. Every 10-mg increase in daily morphine equivalent amount taken preoperatively was associated with a 0.03 decrease in the 12-Item Short-Form Health Survey physical component summary and mental component summary scores, a 0.01 decrease in the EuroQol-5D score, and a 0.5 increase in the Oswestry Disability Index and Neck Disability Index score at twelve months postoperatively. Higher preoperative Modified Somatic Perception Questionnaire and Zung Depression Scale scores were also significant negative predictors (p < 0.05). CONCLUSIONS Increased preoperative opioid consumption, Modified Somatic Perception Questionnaire score, and Zung Depression Scale score prior to undergoing spine surgery predicted worse patient-reported outcomes. This suggests the potential benefit of psychological and opioid screening with a multidisciplinary approach that includes weaning of opioid use in the preoperative period and close opioid monitoring postoperatively.

Preoperative opioid use and its association with perioperative opioid demand and postoperative opioid independence in patients undergoing spine surgery.

Study Design. Prospective cohort. Objective. To assess whether preoperative opioid use is associated with increased perioperative opioid demand and postoperative opioid independence in patients undergoing spine surgery. Summary of Background Data. Previous work has demonstrated increased opioid requirements during the intraoperative and immediate postoperative period in patients with high levels of preoperative opioid use. Despite this, they remain a common agent class used for the management of pain in patients prior to spine surgery. Methods. A total of 583 patients were included. Self-reported daily opioid consumption was obtained preoperatively and converted into morphine equivalent amounts and opioid use was recorded at the 12-month postoperative time. Intraoperative and immediate postoperative opioid demand was calculated. Linear regression analyses for intraoperative and immediate postoperative opioid demand while logistic regression analyses for opioid independence at 12 months including relevant covariates such as depression and anxiety were performed. Results. The median preoperative morphine equivalent amount for the cohort was 8.75 mg, with 55% of patients reporting some degree of opioid use. Younger age, more invasive surgery, anxiety, and primary surgery were significantly associated with increased intraoperative opioid demand (P < 0.05). Younger age, anxiety, and greater preoperative opioid use were significantly associated with increased immediate postoperative opioid demand (P < 0.05). More invasive surgery, anxiety, revision surgery, and greater preoperative opioid use were significantly associated with a decreased incidence of opioid independence at 12 months postoperatively (P < 0.01). Conclusion. Greater preoperative opioid use prior to undergoing spine surgery predicts increased immediate postoperative opioid demand and decreased incidence of postoperative opioid independence. Psychiatric diagnoses in those using preoperative opioids were predictors of continued opioid use at 12 months. Patients may benefit from preoperative counseling that emphasizes minimizing opioid use prior to undergoing spine surgery. Level of Evidence: 2

Quadriceps and patellar tendon ruptures.

The diagnosis of quadriceps and patellar tendon ruptures requires a high index of suspicion and thorough history-taking to assess for medical comorbidities that may predispose patients to tendon degeneration. Radiographic assessment with plain films supplemented by ultrasound and magnetic resonance imaging when the work-up is equivocal further aids diagnosis; however, advanced imaging is often unnecessary in patients with functional extensor mechanism deficits. Acute repair is preferred, and transpatellar bone tunnels serve as the primary form of fixation when the tendon rupture occurs at the patellar insertion, with or without augmentation depending on surgeon preference. Chronic tears and disruptions following total knee arthroplasty are special cases requiring reconstructions with allograft, synthetic mesh, or autograft. Rehabilitation protocols generally allow immediate weight-bearing with the knee locked in extension and crutch support. Limited arc motion is started early with active flexion and passive extension and then advanced progressively, followed by full active range of motion and strengthening. Complications are few but include quadriceps atrophy, knee stiffness, and rerupture. Outcomes are excellent if repair is done acutely, with poorer outcomes associated with delayed repair.

Preoperative narcotic use and its relation to depression and anxiety in patients undergoing spine surgery.

Study Design. Prospective review of registry data at a single institution from October 2010 to June 2012. Objective. To assess whether the amount of preoperative narcotic use is associated with preoperative depression and anxiety in patients undergoing spine surgery for a structural lesion. Summary of Background Data. Previous work suggests that narcotic use and psychiatric comorbidities are significantly related. Among other psychological considerations, depression and anxiety may be associated with the amount of preoperative narcotic use in patients undergoing spine surgery. Methods. Five hundred eighty-three patients undergoing lumbar (60%), thoracolumbar (11%), or cervical spine (29%) were included. Self-reported preoperative narcotic consumption was obtained at the initial preoperative visit and converted to daily morphine equivalent amounts. Preoperative Zung Depression Scale (ZDS) and Modified Somatic Perception Questionnaire (MSPQ) scores were also obtained at the initial preoperative visit and recorded as measures of depression and anxiety, respectively. Resistant and robust bootstrapped multivariable linear regression analysis was performed to determine the association between ZDS and MSPQ scores and preoperative narcotics, controlling for clinically important covariates. Mann-Whitney U tests examined preoperative narcotic use in patients who were categorized as depressed (ZDS ≥ 33) or anxious (MSPQ ≥ 12). Results. Multivariable analysis controlling for age, sex, smoking status, preoperative employment status, and prior spinal surgery demonstrated that preoperative ZDS (P = 0.006), prior spine surgery (P = 0.007), and preoperative pain (0.014) were independent risk factors for preoperative narcotic use. Preoperative MSPQ (P = 0.083) was nearly a statistically significant risk factor. Patients who were categorized as depressed or anxious on the basis of ZDS and MSPQ scores also showed higher preoperative narcotic use than those who were not (P < 0.0001). Conclusion. Depression and anxiety as assessed by ZDS and MSPQ scores were significantly associated with increased preoperative narcotic use, underscoring the importance of thorough psychological and substance use evaluation in patients being evaluated for spine surgery.

Approach to pain management in chronic opioid users undergoing orthopaedic surgery.

Opioids are commonly used for the management of pain in patients with musculoskeletal disorders; however, national attention has highlighted the potential adverse effects of the use of opioid analgesia in this and other nonmalignant pain settings. Chronic opioid users undergoing orthopaedic surgery represent a particularly challenging patient population in regard to their perioperative pain control and outcomes. Preoperative evaluation provides an opportunity to estimate a patient’s preoperative opioid intake, discuss pain-related fears, and identify potential psychiatric comorbidities. Patients using high levels of opioids may also require referral to an addiction specialist. Various regional blockade and pharmaceutical options are available to help control perioperative pain, and a multimodal pain management approach may be of particular benefit in chronic opioid users undergoing orthopaedic surgery.

Increased Preoperative Narcotic Use and Its Association With Postoperative Complications and Length of Hospital Stay in Patients Undergoing Spine Surgery.

Study Design:Prospective cohort analysis. Objective:To assess the effect of preoperative narcotic use on the incidence of 30- and 90-day postoperative complications, as well as length of hospital stay (LOS) in patients undergoing spine surgery. Summary of Background Data:Previous work has associated an increased incidence of complications and length of stay following surgery in patients with increased preoperative narcotic use. Despite this and recent national attention highlighting the negative effects of narcotics, they remain commonly used for the management of pain in patients undergoing spine surgery. Materials And Methods:A total of 583 patients undergoing spine surgery for a structural lesion were evaluated. Self-reported preoperative narcotic consumption was obtained and converted to morphine equivalents at the initial preoperative visit. LOS was recorded upon discharge and presence/type of a postoperative complication within 30/90 days was obtained. A multivariable logistic and linear regression analysis was performed for the incidence of complications and length of stay controlling for clinically important covariates. Results:Narcotic use was not associated with 30- or 90-day complications; however, smoking status was significantly associated with 30-day complications. Increased preoperative narcotic use was significantly associated with increased LOS, as was age, type of surgery, and depression. Conclusions:Increased preoperative narcotic use and depression are associated with increased LOS in patients undergoing spine surgery. We calculated that for every 100 morphine equivalents a patient is taking preoperatively; their stay is extended 1.1 days. Narcotic use was not associated with 30- or 90-day postoperative complications. As reimbursement is bundled before surgery, providing interventions for patients with treatable causes for increased length of stay can save cost overall.
