National Trends in Opioid Prescriptions Following Outpatient Otologic Surgery, 2005-2017

Disparities in Postoperative Pain Management: A Scoping Review of Prescription Practices and Social Determinants of Health

Background: Opioid analgesic therapy has been traditionally used for pain management; however, the variability in patient characteristics, complexity in evaluating pain, availability of treatment within facilities, and U.S. physicians overprescribing opioids have contributed to the current opioid epidemic. Despite large research efforts investigating the patterns of postsurgical pain management and influencing factors, it remains unclear how these overall trends vary across the varying sizes and available resources of academic hospitals, community hospitals, and outpatient surgery centers. The primary aim of this scoping review was to examine the patterns of contemporary postoperative pain management across healthcare settings, including academic medical centers, community hospitals, and outpatient surgery centers. Specifically, this study investigates how prescription practices for opioids, NSAIDs, and acetaminophen are influenced by patient demographics, including sex, race, gender, insurance status, and other social determinants of health (SDoH), to inform equitable and patient-centered pain management strategies. Methods: This study utilized The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) and was used as a reference checklist. The Arksey and O'Malley methodological framework was used to guide the review process. To ensure comprehensive coverage, searches were conducted across three major databases: PubMed, Embase, and Cochrane Library. Results: A total of 43 eligible studies were retained for analysis. The highest reported Healthy People 2030 category was Social and community context (n = 39), while the highest reported category of SDoH was age (n = 36). A total of 34 articles listed sex and age as SDoH. Additional SDoH examined were race/ethnicity (n = 17), insurance (n = 7), employment (n = 1), education (n = 4), and income (n = 1). This review suggests that there are significant gaps in the implementation of institution-specific, patient-centered, and equitable pain management strategies, particularly in academic hospitals, which our findings show have the highest rates of opioid and NSAID prescriptions (n = 26) compared to outpatient surgical centers (n = 8). Findings from our review of the literature demonstrated that while academic hospitals often adopt enhanced recovery protocols aimed at reducing opioid dependence, these protocols can fail to address the diverse needs of at-risk populations, such as those with chronic substance use, low socioeconomic status, or racial and ethnic minorities. Conclusions: Findings from this review are expected to have implications for informing both organizational-specific and nationwide policy recommendations, potentially leading to more personalized and equitable pain management strategies across different healthcare settings. These include guidelines for clinicians on addressing various aspects of postoperative pain management, including preoperative education, perioperative pain management planning, use of different pharmacological and nonpharmacological modalities, organizational policies, and transition to outpatient care.

Opioid Prescribing Patterns Following Lateral Skull Base Spontaneous Cerebrospinal Fluid Leak Repair

OBJECTIVE

To characterize the opioid prescribing patterns for and requirements of patients undergoing repair of spontaneous cerebrospinal fluid (sCSF) leaks of the lateral skull base.

STUDY DESIGN

Retrospective chart review.

SETTING

Tertiary referral center.

PATIENTS

Adults with lateral skull base sCSF leaks who underwent repairs between September 1, 2014, and December 31, 2020.

MAIN OUTCOME MEASURE

Mean morphine milligram equivalents (MMEs) of opioids dispensed to inpatients and prescribed at discharge, additional pain control medications dispensed, and outpatient additional opioid requests were compared between groups.

RESULTS

Of 78 patients included, 46 (59%) underwent repair via a transmastoid (TM), 6 (7.7%) via a middle cranial fossa (MCF), and 26 (33.3%) via a combined TM-MCF approach. Inpatients received a mean of 21.3, 31.4, and 37.6 MMEs per day during admission for the TM, MCF, and combined TM-MCF approaches, respectively ( p = 0.019, ηp 2 = 0.101). Upon discharge, nearly all patients (n = 74, 94.9%) received opioids; 27.3, 32.5, and 37.6 MMEs per day were prescribed after the TM, MCF, and TM-MCF approaches, respectively ( p = 0.015, ηp 2 = 0.093). Five (6.4%) patients requested additional outpatient pain medication, after which three were prescribed 36.7 MMEs per day. Patients with idiopathic intracranial hypertension required significantly more inpatient MMEs than those without (41.5 versus 25.2, p = 0.02, d = 0.689), as did patients with a history of headaches (39.6 versus 23.6, p = 0.042, d = 0.684).

CONCLUSIONS

Patients undergoing sCSF leak repair via the MCF or TM-MCF approaches are prescribed more opioids postoperatively than patients undergoing the TM approach. Patients with a history of headaches or idiopathic intracranial hypertension might require more opioids postoperatively.

Opioid stewardship and perioperative management of pediatric tympanoplasty

OBJECTIVE

To provide insight into the intraoperative management, admission course, pain management, and graft success of microscope- and endoscope-assisted tympanoplasty.

STUDY DESIGN

Retrospective Chart Review.

METHODS

This study included children 18 years and younger who underwent ambulatory tympanoplasty at a tertiary pediatric hospital between January 2018 and December 2020. Medical records were reviewed and information about intraoperative factors, surgical approach, laterality, complications, and post-operative perforation closure success rates was collected. Multivariate analysis was performed to compare and contrast the two surgical approaches.

RESULTS

The review included 321 pediatric patients who underwent a tympanoplasty. Endoscopic tympanoplasty accounted for 17.4%, while microscopic tympanoplasty accounted for 82.6%. In both approaches, the rate of intraoperative complications, postoperative complications, audiological improvements, and perforation closure success rates were statistically similar. However, patients who underwent endoscopic tympanoplasty were 3.96 times less likely to require opioids in the post-anesthesia care unit (PACU) and had a shorter post-operative admission length. This pattern emerged regardless of the type of graft used. Obtaining an autograft was not associated with a higher opioid requirement in the PACU.

CONCLUSION

While both approaches are viable, our findings demonstrate the reduced need for opioids with similar success rates following an endoscopic tympanoplasty. Ultimately, the trade-off for the minimally invasive endoscopic approach appears to be a less painful experience for the child while promoting clinically appropriate opioid stewardship in the perioperative setting.

Multimodal Analgesia and Patient Education Reduce Postoperative Opioid Consumption in Otology

OBJECTIVE

This study sought to validate alternative pain management strategies that can reduce reliance on opioids for postoperative pain management in otology.

STUDY DESIGN

Prospective cohort study.

SETTING

Single tertiary-care facility.

METHODS

Adult patients who underwent outpatient otologic surgery from September 2021 to July 2022 were randomized into treatment cohorts. The opioid monotherapy cohort received a standard opioid prescription. The multimodal analgesia cohort received the same opioid prescription, prescriptions for acetaminophen and naproxen, and additional pain management education with a flyer on discharge. All patients completed a questionnaire 1 week after surgery to evaluate opioid usage and pain scores.

RESULTS

Eighty-six patients completed the study. The opioid monotherapy cohort (n = 42) and multimodal analgesia cohort (n = 44) were prescribed an average of 42.1 ± 20.4 morphine milligram equivalents (MME) and 38.4 ± 5.7 MME, respectively (p = 0.373). Four patients (9.52%) in the opioid monotherapy cohort required opioid refills compared to 1 patient (2.27%) in the multimodal analgesia cohort (p = 0.156). Multivariate analysis demonstrated that the multimodal analgesia cohort consumed significantly fewer opioids on average than the opioid monotherapy cohort (11.9 ± 15.9 MME vs 22.8 ± 28.0 MME, respectively). There were no significant differences in postoperative rehospitalizations (p = 0.317) or Emergency Department visits (p = 0.150). Pain scores on the day of surgery, postoperative day (POD) 1, POD3, and POD7 were not significantly different between cohorts (p = 0.395, 0.896, 0.844, 0.765, respectively).

CONCLUSION

The addition of patient education, acetaminophen, and naproxen to postoperative opioid prescriptions significantly reduced opioid consumption without affecting pain scores, refill rates, or complication rates after otologic surgery.

Opioid Prescribing Patterns After Skull Base Surgery for Vestibular Schwannoma

OBJECTIVE

Excessive opioid prescription is a source of prescription diversion and could contribute to chronic opioid abuse. This study describes the opioid prescribing patterns and risk factors for additional opioid prescription after surgical resection of vestibular schwannoma (VS).

STUDY DESIGN

Retrospective chart review.

SETTING

Single tertiary referral center.

PATIENTS

Adult VS patients undergoing surgical resection between May 2019 and March 2020.

INTERVENTIONS

Opioid use postoperatively and up to 60 days following surgery were characterized from medical records and by querying the state-wide Controlled Substance Utilization Review and Evaluation System.

MAIN OUTCOME MEASURES

The presence of additional opioid prescriptions within 60 days of surgery.

RESULTS

A total of 109 patients (mean age 50 yrs, 65.5% female) were prescribed an average of 138.2 ± 117.8 mg of morphine equivalents (MME). Twenty-two (20.9%) required additional prescriptions of 163.2 ± 103.2 MME. Age, gender, tumor size, or surgical approach (translabyrinthine, retrosigmoid, versus middle fossa) were not associated with additional prescriptions. Patients with additional prescriptions had higher body mass index (BMI 28.8 vs. 25.8 kg/m2, p = 0.015) and required more opioid medications during hospitalization (51.8 vs. 29.1 MME, p = 0.002). On multivariate logistic regression, higher BMI (odds ratio [OR] 1.32; p = 0.001), history of headaches (OR 11.9, p = 0.011), and history of opioid use (OR 29.3, p = 0.008) were associated with additional prescription.

CONCLUSIONS

Additional opioid prescriptions may be necessary in a portion of VS patients undergoing surgery. The choice of surgical approach is not associated with excess opioid requirements. Patients with higher BMI, history of headaches, or preoperative opioid use may require additional prescriptions.

Opioid Prescriptions Following Otologic Surgery: A Population-Based Study

OBJECTIVE

To examine postoperative opioid-prescribing patterns following otologic surgery.

STUDY DESIGN

Retrospective population-based descriptive study.

SETTING

All hospitals in the Canadian province of Ontario.

METHODS

Of all patients with advanced ear surgery between July 1, 2012, and March 31, 2019, 7 cohorts were constructed: tympanoplasty with or without ossiculoplasty (n = 7812), atticotomy/limited mastoidectomy (n = 1371), mastoidectomy (n = 3717), semicircular canal occlusion (SCO; n = 179), stapedectomy (n = 2735), bone-implanted hearing aid insertion (n = 280), and cochlear implant (n = 2169). Prescriptions filled for narcotics postoperatively were calculated per morphine milligram equivalent (MME) opioid dose. Multivariable regression was used to determine predictors of higher opioid doses.

RESULTS

The mean ± SD MMEs prescribed were as follows: tympanoplasty with or without ossiculoplasty, 246.77 ± 1380.78; atticotomy/limited mastoidectomy, 283.32 ± 956.10; mastoidectomy, 280.56 ± 1018.50; SCO, 328.61 ± 1090.86; stapedectomy, 164.64 ± 657.18; bone-implanted hearing aid insertion, 326.11 ± 1054.66; and cochlear implant, 200.87 ± 639.93. SCO (odds ratio [OR], 1.69 [95% CI, 1.16-2.48]) and mastoidectomy (OR, 1.50 [95% CI, 1.36-1.66]) were associated with higher opioid doses than tympanoplasty-ossiculoplasty. Asthma (OR, 1.24 [95% CI, 1.12-1.38]), chronic obstructive pulmonary disease (OR, 1.29 [95% CI, 1.12-1.47]), myocardial infarction (OR, 1.33 [95% CI, 1.05-1.68]), diabetes (OR, 1.22 [95% CI, 1.08-1.39]), and substance-related and addictive disorders (OR, 2.59 [95% CI, 1.67-4.00]) were associated with higher opioid doses prescribed. Overall MME prescribed by year demonstrates a sharp drop from 2017-2018 to 2018-2019.

CONCLUSION

This large comprehensive population study provides insight into the prescribing patterns following otologic surgery. The large amounts prescribed and substantial variation require further study to determine barriers that limit good opioid-prescribing stewardship in the postoperative period.
