Opioid analgesic use after ambulatory surgery: a descriptive prospective cohort study of factors associated with quantities prescribed and consumed.
Ontology highlight
ABSTRACT: Objectives
To prospectively characterise: (1) postoperative opioid analgesic prescribing practices; (2) experience of patients undergoing elective ambulatory surgeries and (3) impact of patient risk for medication misuse on postoperative pain management.Design
Longitudinal survey of patients 7 days before and 7-14 days after surgery.Setting
Academic urban safety-net hospital.Participants
181 participants recruited, 18 surgeons, follow-up data from 149 participants (82% retention); 54% women; mean age: 49 years.Interventions
None.Primary and secondary outcome measures
Total morphine equivalent dose (MED) prescribed and consumed, percentage of unused opioids.Results
Surgeons postoperatively prescribed a mean of 242 total MED per patient, equivalent to 32 oxycodone (5 mg) pills. Participants used a mean of 116 MEDs (48%), equivalent to 18 oxycodone (5 mg) pills (~145 mg of oxycodone remaining per patient). A 10-year increase in patient age was associated with 12 (95% CI (-2.05 to -0.35)) total MED fewer prescribed opioids. Each one-point increase in the preoperative Graded Chronic Pain Scale was associated with an 18 (6.84 to 29.60) total MED increase in opioid consumption, and 5% (-0.09% to -0.005%) fewer unused opioids. Prior opioid prescription was associated with a 55 (5.38 to -104.82) total MED increase in opioid consumption, and 19% (-0.35% to -0.02%) fewer unused opioids. High-risk drug use was associated with 9% (-0.19% to 0.002%) fewer unused opioids. Pain severity in previous 3 months, high-risk alcohol, use and prior opioid prescription were not associated with postoperative prescribing practices.Conclusions
Participants with a preoperative history of chronic pain, prior opioid prescription, and high-risk drug use were more likely to consume higher amounts of opioid medications postoperatively. Additionally, surgeons did not incorporate key patient-level factors (eg, substance use, preoperative pain) into opioid prescribing practices. Opportunities to improve postoperative opioid prescribing include system changes among surgical specialties, and patient education and monitoring.

Project description:This study aims to evaluate the safety and patient satisfaction of a fast-track procedure for cataract surgery under topical anaesthesia without perioperative anaesthesia care. This is a prospective single-centre study including all cataract procedures in the Centre Ambulatoire de la Chirurgie de la Cataracte at the Hospital of Bourges between May and August 2018. Procedures were performed under topical anaesthesia without the presence of a nurse anaesthesiologist or anaesthesiologist, the patient had not fasted, and no peripheral venous line was placed. Only heart rate and oxygen saturation were monitored intraoperatively with pulse oximetry. Incidence and nature of intraoperative adverse events and surgical complications were recorded. Patient satisfaction was assessed using the Iowa Satisfaction with Anaesthesia Scale (ISAS). In total, 651 cataract surgeries were performed among which 614 (94.3%) were uneventful. Thirty (4.6%) intraoperative adverse events and 8 (1.2%) surgical complications were recorded. All surgeries were successfully completed. No medical emergency team intervention or hospital admittance was encountered. The mean ISAS score was 5.7/6, indicating high patient satisfaction. Cataract surgery in an ambulatory cataract surgery centre without perioperative anaesthesia care is a safe procedure with high patient satisfaction for screened patients. Anaesthesia ressources are scarce and may be more beneficial to more complex ophthalmic or non-ophthalmic surgeries.

Project description:BackgroundPublished research on prescribed opioid analgesic (POA) use during pregnancy and birth outcomes is limited in scope and has not adequately adjusted for potential confounding factors. To help address these gaps, we estimated associations between maternal POAs during pregnancy and two adverse birth outcomes using a large population-based dataset, multiple definitions of POA exposure, and several methods to evaluate the influence of both measured and unmeasured confounding factors.Methods and findingsWe obtained data by linking information from several Swedish registers and conducted a retrospective cohort study on a population-based sample of 620,458 Swedish births occurring between 2007 and 2013 (48.6% female; 44.4% firstborn). We evaluated associations between prenatal POA exposure and risk for preterm birth (PTB; <37 gestational weeks) and small for gestational age (SGA; birth weight 2 standard deviations below the expected weight for gestational age or lower). We evaluated the influence of confounding by adjusting for a wide range of measured covariates while comparing exposed and unexposed infants. Additionally, we adjusted for unmeasured confounding factors by using several advanced epidemiological designs. Infants exposed to POAs anytime during pregnancy were at increased risk for PTB compared with unexposed infants (6.4% exposed versus 4.4% unexposed; adjusted odds ratio [OR] = 1.38, 95% confidence interval [CI] 1.31-1.45, p < 0.001). This association was attenuated when we compared POA-exposed infants with acetaminophen-exposed infants (OR = 1.18, 95% CI 1.07-1.30, p < 0.001), infants born to women who used POAs before pregnancy only (OR = 1.05, 95% CI 0.96-1.14, p = 0.27), and unexposed siblings (OR = 0.99, 95% CI 0.85-1.14, p = 0.92). We also evaluated associations with short-term versus persistent POA use during pregnancy and observed a similar pattern of results, although the magnitudes of associations with persistent exposure were larger than associations with any use or short-term use. Although short-term use was not associated with SGA (adjusted ORsingle-trimester = 0.95, 95% CI 0.87-1.04, p = 0.29), persistent use was associated with increased risk for SGA (adjusted ORmultiple-trimester = 1.40, 95% CI 1.17-1.67, p < 0.001) compared with unexposed infants. The association with persistent exposure was attenuated when we used alternative comparison groups (e.g., sibling comparison OR = 1.22, 95% CI 0.60-2.48, p = 0.58). Of note, our study had limitations, including potential bias from exposure misclassification, an inability to adjust for all sources of confounding, and uncertainty regarding generalizability to countries outside of Sweden.ConclusionsOur results suggested that observed associations between POA use during pregnancy and risk of PTB and SGA were largely due to unmeasured confounding factors, although we could not rule out small independent associations, particularly for persistent POA use during pregnancy.

Project description:Limited evidence suggests bariatric surgery may not reduce opioid analgesic use, despite improvements in pain.To determine if use of prescribed opioid analgesics changes in the short and long term after bariatric surgery and to identify factors associated with continued and postsurgery initiated use.Ten U.S. hospitals.The Longitudinal Assessment of Bariatric Surgery-2 is an observational cohort study. Assessments were conducted presurgery, 6 months postsurgery, and annually postsurgery for up to 7 years until January 2015. Opioid use was defined as self-reported daily, weekly, or "as needed" use of a prescribed medication classified as an opioid analgesic.Of 2258 participants with baseline data, 2218 completed follow-up assessment(s) (78.7% were female, median body mass index: 46; 70.6% underwent Roux-en-Y gastric bypass). Prevalence of opioid use decreased after surgery from 14.7% (95% CI: 13.3-16.2) at baseline to 12.9% (95% CI: 11.5-14.4) at month 6 but then increased to 20.3%, above baseline levels, as time progressed (95% CI: 18.2-22.5) at year 7. Among participants without baseline opioid use (n = 1892), opioid use prevalence increased from 5.8% (95% CI: 4.7-6.9) at month 6 to 14.2% (95% CI: 12.2-16.3) at year 7. Public versus private health insurance, more pain presurgery, undergoing subsequent surgeries, worsening or less improvement in pain, and starting or continuing nonopioid analgesics postsurgery were significantly associated with higher risk of postsurgery initiated opioid use.After bariatric surgery, prevalence of prescribed opioid analgesic use initially decreased but then increased to surpass baseline prevalence, suggesting the need for alternative methods of pain management in this population.

Project description:BackgroundOverprescribing of opioids after surgery contributes to long-term abuse. Evaluating opioid prescription patterns and patient-reported opioid use offers an evidence-based method to identify potential overprescription. This quality improvement initiative aimed to reduce and standardize opioid prescriptions upon discharge from an ambulatory oncologic surgery center and evaluate the effect of this change on patients' subsequent opioid use and reported pain.MethodsBetween March 2018 and January 2019, consecutive opioid-naïve patients aged ≥ 18 years who underwent robotic or laparoscopic hysterectomy, radical prostatectomy, or partial nephrectomy, or total mastectomy with or without immediate reconstruction were surveyed 7-10 days postoperatively. Data collected in the pre- (n = 551) and post-standardization (n = 480) cohorts included perception of pain relief, opioids prescribed (verified by electronic medical record review) and consumed, and refills received.ResultsPre-standardization, the median opioid prescription at discharge was 20 pills (interquartile range [IQR] 20-28) or 140 oral morphine milligram equivalents (MME) (IQR 100-150). Median opioid consumption was 2 pills (IQR 0-7) or 10 MME (IQR 0-40) among all services. Opioid prescriptions were later standardized to 7, 8, and 10 pills (35, 40, and 75 MME), in the gynecology, urology, and breast services, respectively. The change was not associated with an increase in reported pain. Refill requests increased postintervention across all surgeries from 4.4% to 7.7%, with the largest increase among patients who underwent breast surgery.ConclusionThe number of opioid pills given at discharge to patients undergoing ambulatory or short-stay cancer surgery can safely be reduced.

Project description:ObjectiveTo describe the contributions of prescribed and non-prescribed opioids to opioid related deaths.DesignPopulation based cohort study.SettingOntario, Canada, from 1 January 2013 to 31 December 2016.ParticipantsAll Ontarians who died of an opioid related cause.ExposureActive opioid prescriptions, defined as those with a duration overlapping the date of death, and recent opioid prescriptions, defined as those dispensed in the 30 and 180 days preceding death. Postmortem toxicology results from the Drug and Drug/Alcohol Related Death database were used to characterise deaths on the basis of presence of prescribed and non-prescribed (that is, diverted or illicit) opioids, overall and stratified by year and age.Results2833 opioid related deaths occurred. An active opioid prescription on the date of death was relatively common but declined slightly throughout the study period (38.2% (241/631) in 2013 and 32.5% (278/855) in 2016; P for trend=0.03). Older people and women were relatively more likely to have an active opioid prescription at time of death. In 2016, 46% (169/364) of people aged 45-64 had an active opioid prescription compared with only 12% (8/69) among those aged 24 or younger (P for trend<0.001). Similarly, 46% (124/272) of women had an active opioid prescription at time of death compared with 26.4% (154/583) of men (P<0.001). Among people with active opioid prescriptions at time of death, 37.8% (375/993) also had evidence of a non-prescribed opioid on postmortem toxicology. By 2016, the non-prescribed opioid most commonly identified after death was fentanyl (41%; 47 of 115 cases). Among people without an active opioid prescription at time of death, fentanyl was detected in 20% (78/390) of deaths in 2013, increasing to 47.5% (274/577) by 2016 (P<0.001).ConclusionsPrescribed, diverted, and illicit opioids all play an important role in opioid related deaths. Although more than half of all opioid related deaths still involved prescription drugs (either dispensed or diverted) in 2016, the increased rate of deaths involving fentanyl between 2015 and 2016 is concerning and suggests the need for a multifactorial approach to this problem that considers both the prescribed and illicit opioid environments.

Project description:Opioids play a critical role in acute postoperative pain management. Our objective was to develop machine learning models to predict postoperative opioid requirements in patients undergoing ambulatory surgery. To develop the models, we used a perioperative dataset of 13,700 patients (≥ 18 years) undergoing ambulatory surgery between the years 2016-2018. The data, comprising of patient, procedure and provider factors that could influence postoperative pain and opioid requirements, was randomly split into training (80%) and validation (20%) datasets. Machine learning models of different classes were developed to predict categorized levels of postoperative opioid requirements using the training dataset and then evaluated on the validation dataset. Prediction accuracy was used to differentiate model performances. The five types of models that were developed returned the following accuracies at two different stages of surgery: 1) Prior to surgery-Multinomial Logistic Regression: 71%, Naïve Bayes: 67%, Neural Network: 30%, Random Forest: 72%, Extreme Gradient Boost: 71% and 2) End of surgery-Multinomial Logistic Regression: 71%, Naïve Bayes: 63%, Neural Network: 32%, Random Forest: 72%, Extreme Gradient Boost: 70%. Analyzing the sensitivities of the best performing Random Forest model showed that the lower opioid requirements are predicted with better accuracy (89%) as compared with higher opioid requirements (43%). Feature importance (% relative importance) of model predictions showed that the type of procedure (15.4%), medical history (12.9%) and procedure duration (12.0%) were the top three features contributing to model predictions. Overall, the contribution of patient and procedure features towards model predictions were 65% and 35% respectively. Machine learning models could be used to predict postoperative opioid requirements in ambulatory surgery patients and could potentially assist in better management of their postoperative acute pain.

Project description:ImportanceInterventions to improve judicious prescribing of opioid analgesics for acute pain are needed owing to the risks of diversion, misuse, and overdose.ObjectiveTo assess the effect of modifying opioid analgesic prescribing defaults in the electronic health record (EHR) on prescribing and health service use.Design, setting, and participantsA cluster randomized clinical trial with 2 parallel arms was conducted between June 13, 2016, and June 13, 2018, in a large urban health care system comprising 32 primary care and 4 emergency department (ED) sites in the Bronx, New York. Data were analyzed using a difference-in-differences method from 6 months before implementation through 18 months after implementation. Data were analyzed from January 2019 to February 2020.InterventionsA default dispense quantity for new opioid analgesic prescriptions of 10 tablets (intervention) vs no change (control) in the EHR.Main outcomes and measuresThe primary outcome was the quantity of opioid analgesics prescribed with the new default prescription. Secondary outcomes were opioid analgesic reorders and health service use within 30 days after the new prescription. Intention-to-treat analysis was conducted.ResultsOverall, 21 331 patients received a new opioid analgesic prescription from 490 prescribers. Comparing the intervention and control arms, site, prescriber, and patient characteristics were similar. For the new prescription, compared with the control arm, patients in the intervention arm had significantly more prescriptions for 10 tablets or fewer (7.6 percentage points; 95% CI, 6.1-9.2 percentage points), a lower number of tablets prescribed (-2.1 tablets; 95% CI, -3.3 to -0.9 tablets), and lower morphine milligram equivalents (MME) prescribed (-14.6 MME; 95% CI, -22.6 to -6.6 MME). Within 30 days after the new prescription, significant differences remained in the number of tablets prescribed (-2.7 tablets; 95% CI, -4.8 to -0.6 tablets), but not MME (-15.8 MME; 95% CI, -33.8 to 2.2 MME). Within this 30-day period, there were no significant differences between the arms in health service use.Conclusions and relevanceIn this study, implementation of a uniform reduced default dispense quantity of 10 tablets for opioid analgesic prescriptions led to a modest reduction in the quantity prescribed initially, without significantly increasing health service use. However, during 30 days after implementation, the influence on prescribing was mixed. Reducing EHR default dispense quantities for opioid analgesics is a feasible strategy that can be widely disseminated and may modestly reduce prescribing.Trial registrationClinicalTrials.gov Identifier: NCT03003832.

Project description:OBJECTIVE:Opioid analgesics may be prescribed to ankylosing spondylitis (AS) patients with pain that is unresponsive to antirheumatic treatment. Our study assessed factors associated with opioid usage in AS. METHODS:A prospective cohort of 706 patients with AS meeting modified New York criteria followed at least 2 years underwent comprehensive clinical evaluation of disease activity and functional impairment. These were assessed by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI). Radiographic severity was assessed by the Bath Ankylosing Spondylitis Radiology Index and modified Stokes Ankylosing Spondylitis Scoring System. Medications taken concurrently with opioids, as well as C-reactive protein (CRP) levels and erythrocyte sedimentation rate (ESR), were determined at each study visit, performed every 6 months. Analyses were carried out at baseline, and longitudinal multivariable models were developed to identify factors independently associated with chronic and intermittent opioid usage over time. RESULTS:Factors significantly associated with opioid usage, especially chronic opioid use, included longer disease duration, smoking, lack of exercise, higher disease activity (BASDAI) and functional impairment (BASFI), depression, radiographic severity, and cardiovascular disease. Patients taking opioids were more likely to be using anxiolytic, hypnotic, antidepressant, and muscle relaxant medications. Multivariable analysis underscored the association with smoking, older age, antitumor necrosis factor agent use, and psychoactive drugs, as well as with subjective but not objective determinants of disease activity. CONCLUSION:Opioid usage was more likely to be associated with subjective measures (depression, BASDAI, BASFI) than objective measures (CRP, ESR), suggesting that pain in AS may derive from sources other than spinal inflammation alone.

Project description:BackgroundRecent studies show a rapid growth among pregnant women using high potency opioids for common pain management during their pregnancy. No study has examined the duration of treatment among strong opioid users and weak opioid users during pregnancy. We aimed to investigate the prevalence of prescribed opioid use during pregnancy, in Quebec; and to compare the duration of opioid treatment between strong opioid users and weak opioid users.MethodsUsing the Quebec Pregnancy Cohort (1998-2015), we included all pregnancies covered by the Quebec Public Prescription Drug Insurance Program. Opioid exposure was defined as filled at least one prescription for any opioid during pregnancy or before pregnancy but with a duration that overlapped the beginning of pregnancy. Prevalence of opioids use was calculated for all pregnancies, according to pregnancy outcome, trimester of exposure, and individual opioids. The duration of opioid use during pregnancy was analyzed according to 8 categories based on cumulative duration (< 90 days vs. ≥90 days), duration of action (short-acting vs. long-acting) and strength of the opioid (weak vs. strong).ResultsOf 442,079 eligible pregnancies, 20,921 (4.7%) were exposed to opioids. Among pregnancies ending with deliveries (n = 249,234), 5.4% were exposed to opioids; the prevalence increased by 40.3% from 3.9% in 1998 to 5.5% in 2015, more specifically a significant increase in the second and third trimesters of pregnancy. Weak opioid, codeine was the most commonly dispensed opioid (70% of all dispensed opioids), followed by strong opioid, hydromorphone (11%), morphine (10%), and oxycodone (5%). The prevalence of codeine use decreased by 47% from 4.3% in 2005 to 2.3% in 2015, accompanied by an increased use of strong opioid, morphine (0.029 to 1.41%), hydromorphone (0.115 to 1.08%) and oxycodone (0.022 to 0.44%), from 1998 to 2015. The average durations of opioid exposure were significantly longer among pregnancies exposed to strong opioid as compared to weak opioid regardless of the cumulative duration or duration of action (P < 0.05).ConclusionsGiven the differences in the safety profile between strong opioids and the major weak opioid codeine, the increased use of strong opioids during pregnancy with longer treatment duration raises public health concerns.

Project description:ImportanceThe opioid epidemic has generated interest in optimizing opioid prescribing after common surgeries. Recent studies have shown a broad range of analgesic prescription patterns following endoscopic sinus surgery (ESS).ObjectiveTo compare the efficacy of different analgesic regimens after ESS.Design, setting, and participantsThis multi-institutional, nonblinded randomized clinical trial was conducted at 6 tertiary centers across the US and Canada and included participants who underwent ESS for acute or chronic rhinosinusitis. The study was conducted from March 2019 to March 2020, and the data were analyzed in November to December 2020.InterventionsAll participants received acetaminophen, 650 mg, as the first-line analgesic. From there, patients were randomized to either oxycodone rescue (oxycodone, 5 mg, as second-line therapy) or ibuprofen rescue (ibuprofen, 600 mg, as second-line therapy, with oxycodone, 5 mg, reserved for breakthrough pain).Main outcomes and measuresBaseline characteristics and disease severity were collected at enrollment. Medication logs, pain scores, and epistaxis measures were collected until postoperative day 7. The primary outcome was the postoperative visual analog scale score for pain. Brief Pain Inventory Pain Severity and Pain Interference Scores were also collected.ResultsA total of 118 patients were randomized (62 [52.5%] oxycodone rescue, 56 [47.5%] ibuprofen rescue; mean [SD] age, 46.7 [16.3] years; 44 women [44.0%]; 83 White [83.0%], 7 Black [7.0%], and 7 Asian individuals [7.0%]). After exclusions for loss to follow-up and noncompliance, 51 remained in the oxycodone rescue group and 49 in the ibuprofen rescue group. The groups had similar demographic characteristics and disease severity. Thirty-two (63%) in the oxycodone rescue group had adequate pain management with acetaminophen only, while 19 (37%) consumed at least 1 oxycodone dose. In the ibuprofen rescue group, 18 (16%) required only acetaminophen, 28 (57%) used only acetaminophen and ibuprofen, and the remaining 13 (26%) consumed 1 or more oxycodone doses. The groups had similar average acetaminophen (9.69 vs 7.96 doses; difference, 1.73; 95% CI, -1.37 to 4.83) and oxycodone (1.89 vs 0.77 doses; difference, 1.13; 95% CI, -0.11 to 2.36) use. Both groups had similar postoperative visual analog scale scores. A subanalysis that compared opioids users with nonusers showed clinically significant lower pain scores in nonusers at multiple postoperative points.Conclusions and relevanceIn this randomized clinical trial, most patients who underwent ESS could be treated postoperatively using a nonopioid regimen of either acetaminophen alone or acetaminophen and ibuprofen. Ibuprofen as a second-line therapy did not reduce overall narcotic consumption, but the overall narcotic use was low in both groups.Trial registrationClinicalTrials.gov Identifier: NCT03783702.
