Reasons for Preoperative Opioid Use Are Associated with Persistent Use following Surgery Among Patients Undergoing Total Knee and Hip Arthroplasty.

OBJECTIVE: Most studies on preoperative opioid use only describe whether or not patients use opioids without characterizing reasons for use. Knowing why patients use opioids can help inform perioperative opioid management. The objective of this study was to explore pain specific reasons for preoperative opioid use prior to total hip and knee arthroplasty (THA and TKA) and their association with persistent use. METHODS: This is a prospective study of 197 patients undergoing THA (n = 99) or TKA (n = 98) enrolled in the Analgesic Outcomes Study between December 2015 and November 2018. All participants reported preoperative opioid use. RESULTS: Reasons for preoperative opioid use were categorized as surgical site pain only (81 [41.1%]); pain in other body areas only (22 [11.2%]); and combined pain (94 [47.7%]). Compared to patients taking opioids for surgical site pain, those with combined reasons for use had 1.24 (P = .40) and 2.28 (P = .16) greater odds of persistent use at 3 and 6 months postoperatively, adjusting for relevant covariates. CONCLUSIONS: This study provides novel insights into the heterogeneity of reasons for presurgical opioid use in patients undergoing a THA or TKA. One key take away is that not all preoperative opioid use is the same and many patients are taking opioids preoperatively for more than just pain at the surgical site. Combined reasons for use was associated with long-term use, suggesting nonsurgical pain, in part, drives persistent opioid use after surgery. Future directions in perioperative care should focus on pain and non-pain reasons for presurgical opioid use to create tailored postoperative opioid weaning plans.

Impact of Prescribing on New Persistent Opioid Use After Cardiothoracic Surgery.

BACKGROUND: New persistent opioid use occurs in 3% to 14% of patients after elective surgery, but is poorly described after cardiothoracic surgery. We examined the association of prescription size with new persistent opioid use after cardiothoracic surgery. METHODS: Opioid-naive Medicare patients undergoing cardiothoracic surgery between 2009 and 2015 were identified. Patients who filled an opioid prescription between 30 days before surgery and 14 days after discharge and with continuous Medicare enrollment 12 months before and 6 months after surgery were selected (n = 24,549). New persistent use was defined as continued prescription fills 91 to 180 days after surgery. Prescription size was reported in oral morphine equivalents. Multivariable regression was performed for risk adjustment, and new persistent use rate was estimated. RESULTS: Patient age was 71 ± 8 years, 9222 (38%) were female, and 20,898 (85%) were white. Overall new persistent use was 12.8% (3153 of 24,549), and declined yearly from 17% in 2009 to 7.1% in 2015 (P < .001). Prescription size, preoperative prescription fills, black race, gastrointestinal complications, disability status, open lung resection, dual eligibility (Medicare and Medicaid), drug and substance abuse, female sex, tobacco use, high comorbidity, pain disorders, longer hospital stay, and younger age were associated with new persistent use. Adjusted new persistent use was 19.6% (95% confidence interval, 18.7% to 20.4%) among patients prescribed more than 450 oral morphine equivalents, compared with 10.4% (95% confidence interval, 9.9% to 10.8%) among those prescribed 200 oral morphine equivalents or less (P < .001). CONCLUSIONS: Size and timing of perioperative opioid prescriptions were the strongest predictors of new persistent opioid use after cardiothoracic surgery. Modifiable risk factors such as prescription size should be targeted to reduce new persistent use.

Postoperative opioid prescribing is not my job: A qualitative analysis of care transitions.

BACKGROUND: Persistent opioid use is common after surgical procedures, and postoperative opioid prescribing often transitions from surgeons to primary care physicians in the months after surgery. It is unknown how surgeons currently transition these patients or the preferred approach to successful coordination of care. This qualitative study aimed to describe transitions of care for postoperative opioid prescribing and identify barriers and facilitators of ideal transitions for potential intervention targets. METHODS: We conducted a qualitative study of surgeons and primary care physicians at a large academic healthcare system using a semi-structured interview guide. Transcripts were independently coded using the Theoretical Domains Framework to identify underlying determinants of physician behaviors. We mapped dominant themes to the Behavior Change Wheel to propose potential interventions targeting these behaiors. RESULTS: Physicians were interviewed between July 2017 and December 2017 beyond thematic saturation (n = 20). Surgeons report passive transitions to primary care physicians after ruling out surgical complications, and these patients often bounce back to the surgeon when primary care physicians are uncertain of the cause of ongoing pain. Ideal practices were identified as setting preoperative expectations and engaging in active transition for postoperative opioid prescribing. We identified 3 behavioral targets for multidisciplinary intervention: knowledge (guidelines for coordination of care), barriers (utilizing support staff for active transition), and professional role (incentive for multidisciplinary collaboration). CONCLUSION: This qualitative study identifies potential interventions aimed at changing physician behaviors regarding transitions of care for postoperative opioid prescribing. Implementation of these interventions could improve coordination of care for patients with persistent postoperative opioid use.

Factors Associated With New Persistent Opioid Usage After Lung Resection.

BACKGROUND: Opioid dependence, misuse, and abuse in the United States continue to rise. Prior studies indicate an important risk factor for persistent opioid use includes elective surgical procedures, though the probability following thoracic procedures remains unknown. We analyzed the incidence and factors associated with new persistent opioid use after lung resection. METHODS: We evaluated data from opioid-naïve cancer patients undergoing lung resection between 2010 and 2014 using insurance claims from the Truven Health MarketScan Databases. New persistent opioid usage was defined as continued opioid prescription fills between 90 and 180 days following surgery. Variables with a p value less than 0.10 by univariate analysis were included in a multivariable logistic regression performed for risk adjustment. Multivariable results were each reported with odds ratio (OR) and confidence interval (CI). RESULTS: A total of 3,026 patients (44.8% men, 55.2% women) were identified as opioid-naïve undergoing lung resection. Mean age was 64 ± 11 years and mean postoperative length of stay was 5.2 ± 3.3 days. A total of 6.5% underwent neoadjuvant therapy, while 21.7% underwent adjuvant therapy. Among opioid-naïve patients, 14% continued to fill opioid prescriptions following lung resection. Multivariable analysis showed that age less than or equal to 64 years (OR, 1.28; 95% CI, 1.03 to 1.59; p = 0.028), male sex (OR, 1.40; 95% CI, 1.13 to 1.73; p = 0.002), postoperative length of stay (OR, 1.32; 95% CI, 1.05 to 1.65; p = 0.016), thoracotomy (OR, 1.58; 95% CI, 1.24 to 2.02; p < 0.001), and adjuvant therapy (OR, 2.19; 95% CI, 1.75 to 2.75; p < 0.001) were independent risk factors for persistent opioid usage. CONCLUSIONS: The greatest risk factors for persistent opioid use (14%) following lung resection were adjuvant therapy and thoracotomy. Future studies should focus on reducing excess prescribing, perioperative patient education, and safe opioid disposal.

Transitions of Care for Postoperative Opioid Prescribing in Previously Opioid-Naïve Patients in the USA: a Retrospective Review.

BACKGROUND: New persistent opioid use is a common postoperative complication, with 6% of previously opioid-naïve patients continuing to fill opioid prescriptions 3-6 months after surgery. Despite these risks, it is unknown which specialties prescribe opioids to these vulnerable patients. OBJECTIVE: To identify specialties prescribing opioids to surgical patients who develop new persistent opioid use. DESIGN, SETTING, AND PARTICIPANTS: Using a national dataset of insurance claims, we identified opioid-naïve patients aged 18-64 years undergoing surgical procedures (2008-2014) who continued filling opioid prescriptions 3 to 6 months after surgery. We then examined opioid prescriptions claims during the 12 months after surgery, and identified prescribing physician specialty using National Provider Identifier codes. MAIN MEASURES: Percentage of opioid prescriptions provided by each specialty evaluated at 90-day intervals during the 12 months after surgery. KEY RESULTS: We identified 5276 opioid-naïve patients who developed new persistent opioid use. During the first 3 months after surgery, surgeons accounted for 69% of opioid prescriptions, primary care physicians accounted for 13%, Emergency Medicine accounted for 2%, Physical Medicine & Rehabilitation (PM&R)/Pain Medicine accounted for 1%, and all other specialties accounted for 15%. In contrast, 9 to 12 months after surgery, surgeons accounted for only 11% of opioid prescriptions, primary care physicians accounted for 53%, Emergency Medicine accounted for 5%, PM&R/Pain Medicine accounted for 6%, and all other specialties provided 25%. CONCLUSIONS: Among surgical patients who developed new persistent opioid use, surgeons provide the majority of opioid prescriptions during the first 3 months after surgery. By 9 to 12 months after surgery, however, the majority of opioid prescriptions were provided by primary care physicians. Enhanced care coordination between surgeons and primary care physicians could allow earlier identification of patients at risk for new persistent opioid use to prevent misuse and dependence.
