Economic Burden of Hospitalizations Associated with Opioid Dependence Among Patients Undergoing Spinal Fusion

Optimization of Postoperative Opioids Use Following Spine Surgery

PURPOSE OF REVIEW

The present investigation evaluated the use of opioids for postoperative pain relief in spinal surgery patients.

RECENT FINDINGS

Pain management is a crucial component of postoperative care that greatly impacts patient outcomes. Postoperative pain management has been shown to allow for earlier mobility, discharge, and return to normal life. Opioids are the standard treatment for postoperative pharmacologic pain relief, but they are associated with the same adverse effects that pain management strives to mitigate. Opioids are associated with a large side effect profile, including a higher risk of various postoperative complications. Opioids are potentially highly addictive and postoperative use is associated with dependence, tolerance, and the current opioid epidemic. Some studies indicate that there are similar surgical outcomes amongst patients independent of whether opioids were prescribed opioids for pain relief.

CONCLUSION

Opioids should only be recommended for postoperative pain management under strict guidance and supervision from physicians. All 50 states have acute pain guidelines in place limiting opioid prescribing. One of the strategies of reducing postoperative opioid consumption is the emphasis on opioid alternatives that should be actively considered and explored prior to resorting to opioids. There are pharmacological and non-pharmacological options available for pain relief that can provide similar levels of analgesia as prescription opioid without unwanted effects such as tolerance and dependency. Proper assessment of patient history and risk factors can aid physicians in tailoring a pain management regimen that is appropriate for each individual patient. More research into efficacy and safety of alternative treatments to opioids is warranted.

The impact of perioperative opioid use on postoperative outcomes following spinal surgery: a meta-analysis of 60 cohort studies with 13 million participants

BACKGROUND CONTEXT

An important factor for the prognosis of spinal surgery is the perioperative use of opioids. However, the relationship is not clear.

PURPOSE

The purpose of this study was to evaluate the effect of perioperative opioid use on the prognosis of patients following spinal surgery.

STUDY DESIGN/SETTING

Systematic review and meta-analysis.

OUTCOME MEASURES

A meta-analysis was conducted using the random-effects method to calculate pooled odds ratios (ORs) with 95% confidence intervals (CIs).

METHODS

The PubMed, Embase, and Cochrane Library databases were systematically searched to find relevant articles that were published until September 2, 2022. The primary outcome was prolonged postoperative opioid use, and secondary outcomes included the length of stay (LOS), reoperation, the time to return to work (RTW), postoperative complications, gastrointestinal complications, new permanent disability, central nervous system events and infection. In addition, subgroup analysis of the primary outcome was conducted to explore the main sources of heterogeneity, and sensitivity analysis of all outcomes was performed to evaluate the stability of the results.

RESULTS

A total of 60 cohort studies involving 13,219,228 individuals met the inclusion criteria. Meta-analysis showed that perioperative opioid use was specifically related to prolonged postoperative opioid use (OR 6.91, 95% CI 6.09 to 7.84, p<.01). Furthermore, the results also showed that perioperative opioid use was significantly associated with prolonged LOS (OR 1.74, 95% CI 1.39 to 2.18, p<.01), postoperative complications (OR 1.72, 95% CI 1.26 to 2.36, p<.01), reoperation (OR 2.38, 95% CI 1.85 to 3.07, p<.01), the time to RTW (OR 0.45, 95% CI 0.39 to 0.52, p<.01), gastrointestinal complications (OR 1.39, 95% CI 1.30 to 1.48, p<.01), central nervous system events (OR 1.99, 95% CI 1.21 to 3.27, p=.07) and infection (OR 1.22, 95% CI 1.09 to 1.36, p=.01). These results were corroborated by the trim-and-fill procedure and leave-one-out sensitivity analyses.

CONCLUSIONS

Based on the current evidence, patients with perioperative opioid use, in comparison to controls, appear to have prolonged postoperative opioid use, which may increase the risk of poor outcomes including prolonged LOS, complications, reoperation, RTW and so on. However, these results must be carefully interpreted as the number of studies included was small and the studies were statistically heterogeneous. These findings may help clinicians to realize the harmfulness of perioperative use of opioids, reduce the use of prescription opioids, necessarily withdraw before operation or significantly wean to the lowest tolerable preoperative amount, and provide some inspiration for standardizing the use of opioids in the future.

Impact of Social Determinants of Health in Spine Surgery

PURPOSE OF REVIEW

Social determinants of health (SDH) are factors that affect patient health outcomes outside the hospital. SDH are "conditions in the environments where people are born, live, learn, work, play, worship, and age that affect a wide range of health, functioning, and quality-of-life outcomes and risks." Current literature has shown SDH affecting patient reported outcomes in various specialties; however, there is a dearth in research relating spine surgery with SDH. The aim of this review article is to identify connections between SDH and post-operative outcomes in spine surgery. These are important, yet understudied predictors that can impact health outcomes and affect health equity.

RECENT FINDINGS

Few studies have shown associations between SDH pillars (environment, race, healthcare, economic, and education) and spine surgery outcomes. The most notable relationships demonstrate increased disability, return to work time, and pain with lower income, education, environmental locations, healthcare status and/or provider. Despite these findings, there remains a significant lack of understanding between SDH and spine surgery. Our manuscript reviews the available literature comparing SDH with various spine conditions and surgeries. We organized our findings into the following narrative themes: 1) education, 2) geography, 3) race, 4) healthcare access, and 5) economics.

Substance Use Disorders Are Independently Associated with Hospital Readmission Among Patients with Brain Tumors

BACKGROUND

Research on the effects of substance use disorders (SUDs) on postoperative outcomes within neurosurgical oncology has been limited. Therefore, the present study sought to quantify the effect of having a SUD on hospital length of stay, postoperative complication incidence, discharge disposition, hospital charges, 90-day readmission rates, and 90-day mortality rates following brain tumor surgery.

METHODS

The present study used data from patients who received surgical resection for brain tumor at a single institution between January 1, 2017, and December 31, 2019. The Mann-Whitney U test was used for bivariate analysis of continuous variables and Fisher exact test was used for bivariate analysis of categorical variables. Multivariate analysis was conducted using logistic regression models.

RESULTS

Our study cohort included a total of 2519 patients, 124 (4.9%) of whom had at least 1 SUD. More specifically, 90 (3.6%) patients had an alcohol use disorder, 27 (1.1%) had a cannabis use disorder, and 12 (0.5%) had an opioid use disorder. On bivariate analysis, 90-day hospital readmission was the only postoperative outcome significantly associated with a SUD (odds ratio 2.21, P = 0.0011). When controlling for patient age, sex, race, marital status, insurance, brain tumor diagnosis, 5-factor modified frailty index score, American Society of Anesthesiologists score, and surgery number, SUDs remained significantly and independently associated with 90-day readmission (odds ratio 1.82, P = 0.013).

CONCLUSIONS

In patients with brain tumor, SUDs significantly and independently predict 90-day hospital readmission after surgery. Targeted management of patients with SUDs before and after surgery can optimize patient outcomes and improve the provision of high-value neurosurgical care.

Management of Postoperative Pain in Patients Following Spine Surgery: A Narrative Review

Perioperative pain management is a unique challenge in patients undergoing spine surgery due to the increased incidence of both pre-existing chronic pain conditions and chronic postsurgical pain. Peri-operative planning and counseling in spine surgery should involve an interdisciplinary approach that includes consideration of patient-level risk factors, as well as pharmacologic and non-pharmacologic pain management techniques. Consideration of psychological factors and patient focused education as an adjunct to these measures is paramount in developing a personalized perioperative pain management plan. Understanding the currently available body of knowledge surrounding perioperative opioid management, management of opioid use disorder, regional/neuraxial anesthetic techniques, ketamine/lidocaine infusions, non-opioid oral analgesics, and behavioral interventions can be useful in developing a comprehensive, multi-modal treatment plan among patients undergoing spine surgery. Although many of these techniques have proved efficacious in the immediate postoperative period, long-term follow-up is needed to define the impact of such approaches on persistent pain and opioid use. Future techniques involving the use of precision medicine may help identify phenotypic and physiologic characteristics that can identify patients that are most at risk of developing persistent postoperative pain after spine surgery.
