Perry, Allison; Wheeler-Martin, Katherine; Terlizzi, Kelly; Krawczyk, Noa; Jent, Victoria; Hasin, Deborah S; Neighbors, Charles; Mannes, Zachary L; Doan, Lisa V; Pamplin, John R; Townsend, Tarlise N; Crystal, Stephen; Martins, Silvia S; Cerdá, Magdalena
OBJECTIVE:To assess whether chronic pain increases the risk of COVID-19 complications, and if opioid use disorder (OUD) differentiates this risk, among New York State (NYS) Medicaid beneficiaries. DESIGN/SETTING/SUBJECTS/METHODS:This was a retrospective cohort study in New York State Medicaid claims data. We evaluated Medicaid claims from March 2019-December 2020 to determine whether chronic pain increased the risk of COVID-19 emergency department (ED) visits, hospitalizations and complications, and whether this relationship differed by OUD status. We included beneficiaries aged 18-64 years with 10 months of prior enrollment. Patients with chronic pain were propensity score matched to those without chronic pain on demographics, utilization, and comorbidities to control for confounders, and stratified by OUD. Complementary log-log regressions estimated hazard ratios (HR) of COVID-19 ED visits and hospitalizations; logistic regressions estimated odds ratios (OR) of hospital complications and readmissions within 0-30, 31-60, and 61-90 days. RESULTS:Among 773,880 adults, chronic pain was associated with greater hazards of COVID-related ED visits (HR, 1.22 [95% CI, 1.16-1.29]) and hospitalizations (HR, 1.19 [95% CI 1.12-1.27]). Patients with chronic pain and OUD had even greater hazards of hospitalization (HR, 1.25 [95% CI, 1.07-1.47]) and increased odds of hepatic- and cardiac-related events (OR 1.74 [95% CI 1.10, 2.74]). CONCLUSIONS:Chronic pain increased the risk of COVID-19 ED visits and hospitalizations. Presence of OUD further increased the risk of COVID-19 hospitalizations and odds of hepatic- and cardiac-related events. Results highlight intersecting risks among a vulnerable population and can inform tailored COVID-19 management.

Dickerson, David M; Mariano, Edward R; Szokol, Joseph W; Harned, Michael; Clark, Randall M; Mueller, Jeffrey T; Shilling, Ashley M; Udoji, Mercy A; Mukkamala, S Bobby; Doan, Lisa; Wyatt, Karla E K; Schwalb, Jason M; Elkassabany, Nabil M; Eloy, Jean D; Beck, Stacy L; Wiechmann, Lisa; Chiao, Franklin; Halle, Steven G; Krishnan, Deepak G; Cramer, John D; Ali Sakr Esa, Wael; Muse, Iyabo O; Baratta, Jaime; Rosenquist, Richard; Gulur, Padma; Shah, Shalini; Kohan, Lynn; Robles, Jennifer; Schwenk, Eric S; Allen, Brian F S; Yang, Stephen; Hadeed, Josef G; Schwartz, Gary; Englesbe, Michael J; Sprintz, Michael; Urish, Kenneth L; Walton, Ashley; Keith, Lauren; Buvanendran, Asokumar
Significant knowledge gaps exist in the perioperative pain management of patients with a history of chronic pain, substance use disorder, and/or opioid tolerance as highlighted in the US Health and Human Services Pain Management Best Practices Inter-Agency Task Force 2019 report. The report emphasized the challenges of caring for these populations and the need for multidisciplinary care and a comprehensive approach. Such care requires stakeholder alignment across multiple specialties and care settings. With the intention of codifying this alignment into a reliable and efficient processes, a consortium of 15 professional healthcare societies was convened in a year-long modified Delphi consensus process and summit. This process produced seven guiding principles for the perioperative care of patients with chronic pain, substance use disorder, and/or preoperative opioid tolerance. These principles provide a framework and direction for future improvement in the optimization and care of 'complex' patients as they undergo surgical procedures.

Single-Dose of Postoperative Ketamine for Postoperative Pain After Mastectomy: A Pilot Randomized Controlled Trial

Doan, Lisa V.; Li, Anna; Brake, Lee; Ok, Deborah; Jee, Hyun Jung; Park, Hyung; Cuevas, Randy; Calvino, Steven; Guth, Amber; Schnabel, Freya; Hiotis, Karen; Axelrod, Deborah; Wang, Jing
Background and Objectives: Perioperative ketamine has been shown to reduce opioid consumption and pain after surgery. Ketamine is most often given as an infusion, but an alternative is single-dose ketamine. Single-dose ketamine at up to 1 mg/kg has been shown to reduce symptoms of depression, and a wide range of dosages has been used for pain in the emergency department. However, limited data exists on the tolerability and efficacy of a single-dose of ketamine at 0.6 mg/kg for pain when administered immediately after surgery. We conducted a pilot study of single-dose ketamine in patients undergoing mastectomy with reconstruction, hypothesizing that a single-dose of ketamine is well tolerated and can relieve postoperative pain and improve mood and recovery. Methods: This is a randomized, single-blind, placebo-controlled, two-arm parallel, single-center study. Thirty adult women undergoing mastectomy with reconstruction for oncologic indication received a single-dose of ketamine (0.6mg/kg) or placebo after surgery in the post-anesthesia care unit (PACU). Patients were followed through postoperative day (POD) 7. The primary outcome was postoperative pain measured by the Brief Pain Inventory (BPI) pain subscale on POD 1 and 2. Secondary outcomes include effects on opioid use, PROMIS fatigue and sleep, mood, Quality of Recovery-15, and the Breast Cancer Pain Questionnaire. Results: Side effects were minor and not significantly different in frequency between groups. The ketamine group reported lower scores on the BPI pain severity subscale, especially at POD 7; however, the difference was not statistically significant. There were no statistically significant differences between ketamine and placebo groups for the secondary outcomes. Conclusion: A single-dose of ketamine at 0.6mg/kg administered postoperatively in the PACU is well tolerated in women undergoing mastectomy and may confer better pain control up to one week after surgery. Future studies with larger sample sizes are necessary to adequately characterize the effect of postoperative single-dose ketamine on pain control in this population.

Implementing Telemedicine During the COVID-19 Pandemic: Disparities in Utilization in an Urban Pain Medicine Practice

Rockholt, Mika M.; Addae, Gifty; Chee, Alexander; Chin, Wanda; Cuff, Germaine; Wang, Jing; Umeh, Uchenna O.; Doan, Lisa V.
Purpose: The COVID-19 pandemic led to a drastic expansion in utilizing telemedicine, circumventing some of the geographical barriers to accessing pain care. However, uncertainties around the impact of telemedicine across various sociodemographic groups still exist, prompting further exploration. Therefore, this study aimed to evaluate the impact of sociodemographic factors in telemedicine utilization during and after the COVID-19 pandemic. Patients and methods: All outpatient non-procedural visits at the pain medicine division of a large academic institution in the epicenter of the pandemic (New York, USA), between March 2019 and October 2021, were retrospectively included. Sociodemographic data including gender, age, ethnicity/race, postal code, and type of health insurance, across three time periods associated with the COVID-19 pandemic-pre-lockdown (in-office visits only), lockdown (telemedicine visits only) and post-lockdown (offering both in-office and telemedicine visits) "“ were analyzed and compared. Results: In total, 12,615 unique patients-The majority being women (58%)-were seen during the whole study period. In the post-lockdown period, telemedicine was utilized by 42% of all patients. Follow-up visits, younger patients, white patients, patients residing further away from the hospital, and privately insured patients were more likely to utilize telemedicine post-lockdown (p <0.05). Older patients, minorities, Manhattan residents, and Medicare/Medicaid recipients, were more likely to use in-office visits post-lockdown (p <0.05). Conclusion: We identified disparities in the utilization of telemedicine in Pain Medicine, which may be due to socioeconomic factors such as lack of access to reliable internet access, cost of devices, and technological know-how. This emphasizes the need for further studies to better understand the reasons for and barriers to telemedicine use. This could help inform policymaking to safeguard equitable access to telemedicine use for pain care.

In search of a composite biomarker for chronic pain by way of EEG and machine learning: where do we currently stand?

Rockholt, Mika M; Kenefati, George; Doan, Lisa V; Chen, Zhe Sage; Wang, Jing
Machine learning is becoming an increasingly common component of routine data analyses in clinical research. The past decade in pain research has witnessed great advances in human neuroimaging and machine learning. With each finding, the pain research community takes one step closer to uncovering fundamental mechanisms underlying chronic pain and at the same time proposing neurophysiological biomarkers. However, it remains challenging to fully understand chronic pain due to its multidimensional representations within the brain. By utilizing cost-effective and non-invasive imaging techniques such as electroencephalography (EEG) and analyzing the resulting data with advanced analytic methods, we have the opportunity to better understand and identify specific neural mechanisms associated with the processing and perception of chronic pain. This narrative literature review summarizes studies from the last decade describing the utility of EEG as a potential biomarker for chronic pain by synergizing clinical and computational perspectives.

Variations in Epidural Steroid Injection Practice Patterns by Pain Medicine Physicians in the United States

Bingham, Nishan; Dhall, Raymon; Montuori, Michael; Padjen, Kristoffer; Gharibo, Christopher; Doan, Lisa
BACKGROUND:Epidural steroid injections (ESI) are one of the most commonly performed pain procedures; however, there has been variation in techniques and approaches amongst pain physicians in the United States. The formation of a multidisciplinary working group was made with considerations to help guide ESI practice. OBJECTIVE:Pain medicine physicians in the United States were surveyed in order to provide an update on current practices for both transforaminal and interlaminar ESI. STUDY DESIGN AND SETTING/METHODS:This was a cross-sectional survey of pain medicine physicians in the United States. METHODS:This study was approved by the institutional review board of our institution. Based on the American Society of Interventional Pain Physicians membership database, an email list was generated, and a web-based survey was sent to interventional pain physicians at academic centers, private practices, government hospitals, and community settings across the United States. Cervical, lumbar, and caudal ESI sections were divided into questions regarding preferences for fluoroscopic views, injectates, and techniques. RESULTS:A total of 261 responses were analyzed. All but one used fluoroscopy for lumbar ESI. There were variations in methods to detect intravascular uptake, choice of injectate, and the use of particulate steroids for lumbar transforaminal epidural steroid injection (TFESI). LIMITATIONS/CONCLUSIONS:The response rate is a limitation, and thus the results may not be representative of all pain medicine physicians in the United States. CONCLUSIONS:Since the 2015 multidisciplinary pain workgroup recommendations were made for ESI, there appears to be a trend towards following these guidelines compared to prior surveys looking at ESI practices. However, our survey shows there continues to be variations in ESI practice that deviates from these guidelines.

Mariano, Edward R; Dickerson, David M; Szokol, Joseph W; Harned, Michael; Mueller, Jeffrey T; Philip, Beverly K; Baratta, Jaime L; Gulur, Padma; Robles, Jennifer; Schroeder, Kristopher M; Wyatt, Karla E K; Schwalb, Jason M; Schwenk, Eric S; Wardhan, Richa; Kim, Todd S; Higdon, Kent K; Krishnan, Deepak G; Shilling, Ashley M; Schwartz, Gary; Wiechmann, Lisa; Doan, Lisa V; Elkassabany, Nabil M; Yang, Stephen C; Muse, Iyabo O; Eloy, Jean D; Mehta, Vikas; Shah, Shalini; Johnson, Rebecca L; Englesbe, Michael J; Kallen, Amanda; Mukkamala, S Bobby; Walton, Ashley; Buvanendran, Asokumar
The US Health and Human Services Pain Management Best Practices Inter-Agency Task Force initiated a public-private partnership which led to the publication of its report in 2019. The report emphasized the need for individualized, multimodal, and multidisciplinary approaches to pain management that decrease the over-reliance on opioids, increase access to care, and promote widespread education on pain and substance use disorders. The Task Force specifically called on specialty organizations to work together to develop evidence-based guidelines. In response to this report's recommendations, a consortium of 14 professional healthcare societies committed to a 2-year project to advance pain management for the surgical patient and improve opioid safety. The modified Delphi process included two rounds of electronic voting and culminated in a live virtual event in February 2021, during which seven common guiding principles were established for acute perioperative pain management. These principles should help to inform local action and future development of clinical practice recommendations.

Doan, Lisa V; Padjen, Kristoffer; Ok, Deborah; Gover, Adam; Rashid, Jawad; Osmani, Bijan; Avraham, Shirley; Wang, Jing; Kendale, Samir
To examine the association of preoperative opioids and/or benzodiazepines on postoperative outcomes in total knee and hip arthroplasty, we retrospectively compared postoperative outcomes in those prescribed preoperative opioids and/or benzodiazepines versus those who were not who underwent elective total knee and hip arthroplasty at a single urban academic institution. Multivariable logistic regression was performed for readmission rate, respiratory failure, infection, and adverse cardiac events. Multivariable zero-truncated negative binomial regression was used for length of stay. After exclusions, there were 4307 adult patients in the study population, 2009 of whom underwent total knee arthroplasty and 2298 of whom underwent total hip arthroplasty. After adjusting for potential confounders, preoperative benzodiazepine use was associated with increased odds of readmission (p < 0.01). Preoperative benzodiazepines were not associated with increased odds of respiratory failure nor increased length of stay. Preoperative opioids were not associated with increased odds of the examined outcomes. There were insufficient numbers of infection and cardiac events for analysis. In this study population, preoperative benzodiazepines were associated with increased odds of readmission. Preoperative opioids were not associated with increased odds of the examined outcomes. Studies are needed to further examine risks associated with preoperative benzodiazepine use.

Detecting acute pain signals from human EEG

Sun, Guanghao; Wen, Zhenfu; Ok, Deborah; Doan, Lisa; Wang, Jing; Chen, Zhe Sage
BACKGROUND:Advances in human neuroimaging has enabled us to study functional connections among various brain regions in pain states. Despite a wealth of studies at high anatomic resolution, the exact neural signals for the timing of pain remain little known. Identifying the onset of pain signals from distributed cortical circuits may reveal the temporal dynamics of pain responses and subsequently provide important feedback for closed-loop neuromodulation for pain. NEW METHOD/UNASSIGNED:Here we developed an unsupervised learning method for sequential detection of acute pain signals based on multichannel human EEG recordings. Following EEG source localization, we used a state-space model (SSM) to detect the onset of acute pain signals based on the localized regions of interest (ROIs). RESULTS:We validated the SSM-based detection strategy using two human EEG datasets, including one public EEG recordings of 50 subjects. We found that the detection accuracy varied across tested subjects and detection methods. We also demonstrated the feasibility for cross-subject and cross-modality prediction of detecting the acute pain signals. COMPARISON WITH EXISTING METHODS/UNASSIGNED:In contrast to the batch supervised learning analysis based on a support vector machine (SVM) classifier, the unsupervised learning method requires fewer number of training trials in the online experiment, and shows comparable or improved performance than the supervised method. CONCLUSIONS:Our unsupervised SSM-based method combined with EEG source localization showed robust performance in detecting the onset of acute pain signals.
