Postoperative Opioid Consumption After Discharge: An Update From the Michigan Surgical Quality Collaborative Registry

Objective: To evaluate opioid consumption for 21 procedures over 4 years from the Michigan Surgical Quality Collaborative (MSQC) registry and update post-discharge prescribing guidelines. Background: Opioids remain a common treatment for postoperative pain of moderate-to-severe intensity not adequately addressed by nonopioid analgesics, but excessive prescribing correlates with increased usage. This analysis provides updates and compares patient-reported consumption in response to new guidelines. Methods: We examined data from the MSQC registry for opioid-naive adult patients undergoing surgery between January 1, 2018, and October 31, 2021. The primary outcome was patient-reported opioid consumption in oxycodone 5 mg equivalents. Guidelines were anchored to the 75th percentile of consumption, updating previous guidelines from January 2020 based on data from January 1, 2018, to May 31, 2019. Results: 39,493 opioid-naive surgical patients (average age 53.8 years [SD 16.4], 56.3% female, 19.1% non-White, 43.9% with public insurance) were included. Guidelines did not change for 7 of the 16 procedures including the most common procedures: minor hernia, laparoscopic cholecystectomy, laparoscopic appendectomy, and laparoscopic hysterectomy. Recommended prescribing ranges were lower for 9 procedures, with most (8) procedures having a reduction of 5 pills. Prescribing guidelines were developed for 5 new procedures. All procedures had upper-limit guidelines of 10 pills or less. Conclusions: For most procedures, patient-reported opioid consumption decreased between 2018 and 2021 when compared to the period between 2018 and 2019. New guidelines were established for a dozen procedures to balance maximizing pain control with reducing harms from inappropriate prescribing.

Frailty Status, Not Just Age, is Associated With Postoperative Opioid Consumption: A Retrospective, Population-based Analysis

Objective: To assess the relationship between postoperative opioid consumption and frailty status. Background: Physiologic reserve can be assessed through both chronologic age as well as measures of frailty. Although prior studies suggest that older individuals may require less opioid following surgery, chronologic age, and frailty do not always align, and little is known regarding postoperative opioid consumption patterns by frailty. Methods: We conducted a retrospective analysis of opioid-naïve adult patients undergoing common general, vascular, and gynecologic procedures across a statewide quality improvement program from November 6, 2017 to February 28, 2021. Our primary outcome was postoperative patient-reported opioid consumption within 30 days of surgery in oral morphine equivalents (OME). Our primary exposure was frailty status defined by the modified frailty index (mFi-5) criteria. Other covariates included patient demographic and clinical attributes, procedural factors, discharge opioid prescription size, and postoperative complications. Linear regression was performed to assess the association of frailty status and opioid consumption, stratified by age. Results: In this cohort of 34,854 patients, 10,596 had an mFi-5 score of ≤1 and 3,635 had a score of >1. A score of >1 was associated with increased patient-reported opioid consumption (OMEs 3.3 greater; 95% CI = 1.5–5.1). This held true for individuals over 65 (OMEs 2.7 greater; 95% CI = 0.2–5.1). Frailty status, regardless of score, was negatively associated with an opioid prescription at discharge. Conclusions: Frailty status is associated with increased opioid consumption after common operations. Future prescribing guidelines and outcomes analyses should consider this marker when reviewing opioid consumption data and related adverse outcomes.

Prescribed Opioid Dosages, Payer Type, and Self-Reported Outcomes After Surgical Procedures in Michigan, 2018-2020

Collaborative quality improvement (CQI) models, often supported by private payers, create hospital networks to improve health care delivery. Recently, these systems have focused on opioid stewardship; however, it is unclear whether reduction in postoperative opioid prescribing occurs uniformly across health insurance payer types. To evaluate the association between insurance payer type, postoperative opioid prescription size, and patient-reported outcomes in a large statewide CQI model. This retrospective cohort study used data from 70 hospitals within the Michigan Surgical Quality Collaborative clinical registry for adult patients (age ≥18 years) undergoing general, colorectal, vascular, or gynecologic surgical procedures between January 1, 2018, and December 31, 2020. Insurance type, classified as private, Medicare, or Medicaid. The primary outcome was postoperative opioid prescription size in milligrams of oral morphine equivalents (OME). Secondary outcomes were patient-reported opioid consumption, refill rate, satisfaction, pain, quality of life, and regret about undergoing surgery. A total of 40 149 patients (22 921 [57.1%] female; mean [SD] age, 53 [17] years) underwent surgery during the study period. Within this cohort, 23 097 patients (57.5%) had private insurance, 10 667 (26.6%) had Medicare, and 6385 (15.9%) had Medicaid. Unadjusted opioid prescription size decreased for all 3 groups during the study period from 115 to 61 OME for private insurance patients, from 96 to 53 OME for Medicare patients, and from 132 to 65 OME for Medicaid patients. A total of 22 665 patients received a postoperative opioid prescription and had follow-up data for opioid consumption and refill. The rate of opioid consumption was highest among Medicaid patients throughout the study period (16.82 OME [95% CI, 12.57-21.07 OME] greater than among patients with private insurance) but increased the least over time. The odds of refill significantly decreased over time for patients with Medicaid compared with patients with private insurance (odds ratio, 0.93; 95% CI, 0.89-0.98). Adjusted refill rates for private insurance remained between 3.0% and 3.1% over the study period; adjusted refill rates among Medicare and Medicaid patients decreased from 4.7% to 3.1% and 6.5% to 3.4%, respectively, by the end of the study period. In this retrospective cohort study of surgical patients in Michigan from 2018 to 2020, postoperative opioid prescription size decreased across all payer types, and differences between groups narrowed over time. Although funded by private payers, the CQI model appeared to have benefitted patients with Medicare and Medicaid as well.

What evidence is needed to inform postoperative opioid consumption guidelines? A cohort study of the Michigan Surgical Quality Collaborative

Machine learning nonresponse adjustment of patient-reported opioid consumption data to enable consumption-informed postoperative opioid prescribing guidelines.

Post-discharge opioid consumption is a crucial patient-reported outcome informing opioid prescribing guidelines, but its collection is resource-intensive and vulnerable to inaccuracy due to nonresponse bias. We developed a post-discharge text message-to-web survey system for efficient collection of patient-reported pain outcomes. We prospectively recruited surgical patients at Beth Israel Deaconess Medical Center in Boston, Massachusetts from March 2019 through October 2020, sending an SMS link to a secure web survey to quantify opioids consumed after discharge from hospitalization. Patient factors extracted from the electronic health record were tested for nonresponse bias and observable confounding. Following targeted learning-based nonresponse adjustment, procedure-specific opioid consumption quantiles (medians and 75th percentiles) were estimated and compared to a previous telephone-based reference survey. 6553 patients were included. Opioid consumption was measured in 44% of patients (2868), including 21% (1342) through survey response. Characteristics associated with inability to measure opioid consumption included age, tobacco use, and prescribed opioid dose. Among the 10 most common procedures, median consumption was only 36% of the median prescription size; 64% of prescribed opioids were not consumed. Among those procedures, nonresponse adjustment corrected the median opioid consumption by an average of 37% (IQR: 7, 65%) compared to unadjusted estimates, and corrected the 75th percentile by an average of 5% (IQR: 0, 12%). This brought median estimates for 5/10 procedures closer to telephone survey-based consumption estimates, and 75th percentile estimates for 2/10 procedures closer to telephone survey-based estimates. SMS-recruited online surveying can generate reliable opioid consumption estimates after nonresponse adjustment using patient factors recorded in the electronic health record, protecting patients from the risk of inaccurate prescription guidelines.

Predictors of low and high opioid tablet consumption after inguinal hernia repair: an ACHQC opioid reduction task force analysis.

Prescribing and consumption of opioids remain highly variable. Using a national hernia registry, we aimed to identify patient and surgery specific factors associated with low and high opioid tablet consumption after inguinal hernia repair. This was a retrospective cross-sectional study evaluating patients undergoing elective inguinal hernia repair with 30-day follow-up and patient-reported opioid consumption from March 2019 to March 2021 using the Abdominal Core Health Quality Collaborative. Clinically significant patient demographics, comorbidities, operative details, quality-of-life measurements, and surgeon prescribing data were entered into a multivariable logistic regression model to identify statistically significant predictors of patients who took no opioid tablets or >10 tablets. A total of 1937 patients were analyzed. Operations included 59% laparoscopic or robotic, 35% open mesh, and 6% open non-mesh repairs. Of these patients, 50% reported taking zero, 42% took 1-10, and 8% took ≥10 opioid tablets at 30-day follow-up. Patients who were older (OR 1.55, 95% CI 1.34-1.79, p-value <0.001), ASA ≤ 2 (OR 1.56, 95% CI 1.2-2.01, p-value <0.001), had no preoperative opioid use at baseline (OR 2.29, 95% CI 1.31-4.03, p-value = 0.004), had local anesthetic with general anesthesia (OR 1.39, 95% CI 1.0.5-1.85, p-value = 0.022), or prescribed <7 opioid tablets (OR 2.27, 95% CI 1.96-2.62, p-value <0.001) were more likely to take no opioid tablets. Older, healthier, opioid naïve patients with local anesthetic administered during elective inguinal hernia repair are most likely to not require opioids. Surgeon prescribing-arguably the most modifiable factor-independently correlates with both low and high opioid consumption.

Impact of Timing of Targeted Muscle Reinnervation on Pain and Opioid Intake Following Major Limb Amputation.

Targeted muscle reinnervation (TMR) has been shown to play an important role in managing neuromas. However, the impact of the timing of TMR on pain visual analogue scale (VAS) scores or patient opioid use has not been thoroughly explored. We hypothesized that TMR performed acutely would lead to lower VAS scores and decreased opioid intake. Prospectively collected data from an amputation registry at a single institution were utilized to identify patients who underwent TMR. Acute TMR was defined as TMR performed within 1 month of the major limb amputation. Primary outcomes included VAS pain scores and patient-reported opioid consumption. In all, 25 patients (26 limbs) were identified in the acute group, and 18 patients (18 limbs) were identified in the delayed group. At intermediate follow-up (between 4 and 8 months postoperatively) and at final follow-up, the average pain VAS score in the delayed TMR group was significantly higher than that in the acute group (5.2 vs. 1.9 at intermediate P = .01 and 6.2 vs. 1.9 at final P = .002). In all, 84% of the amputees overall were not consuming opioid medications at the time of final follow-up (79% acute, 88% delayed, P = .72). There were no statistically significant differences in opioid consumption between the acute and delayed group at intermediate follow-up (P = .35) or at final follow-up (P = .68). TMR is an effective procedure to reduce pain following major limb amputation. Patients with TMR performed acutely had significantly lower VAS pain scores at both intermediate and final follow-up than patients with TMR performed in a delayed setting. Therapeutic II.

Association Between Default Number of Opioid Doses in Electronic Health Record Systems and Opioid Prescribing to Adolescents and Young Adults Undergoing Tonsillectomy

In prior studies, decreasing the default number of doses in opioid prescriptions written in electronic health record systems reduced opioid prescribing. However, these studies did not rigorously assess patient-reported outcomes, and few included pediatric patients. To evaluate the association between decreasing the default number of doses in opioid prescriptions written in electronic health record systems and opioid prescribing and patient-reported outcomes among adolescents and young adults undergoing tonsillectomy. This nonrandomized clinical trial included adolescents and young adults aged 12 to 50 years undergoing tonsillectomy from October 1, 2019, through July 31, 2021, at a tertiary medical center. The treatment group comprised patients from a pediatric otolaryngology service (mostly aged 12-21 years) and the control group comprised patients from a general otolaryngology service (mostly aged 18-25 years). Data on patient-reported opioid consumption and outcomes were collected via a survey on postoperative day 14. Based on opioid consumption among pediatric otolaryngology patients before the intervention, the default number of opioid doses was decreased from 30 to 12 in a tonsillectomy order set. This change occurred only for pediatric otolaryngology patients. Proportion of patients with 12 doses in the discharge opioid prescription, number of doses in this prescription, and refills and pain-related visits within 2 weeks of surgery. In a secondary analysis of patients completing the postoperative survey, patient-reported opioid consumption, pain control, sleep disturbance, anxiety, and depression were assessed. Linear or log-linear difference-in-differences models were fitted, adjusting for patients' demographic characteristics and presence of a mental health or substance use disorder. The study included 237 patients (147 female patients [62.0%]; mean [SD] age, 17.3 [3.6] years). Among 131 pediatric otolaryngology patients, 1 of 70 (1.4%) in the preintervention period and 27 of 61 (44.3%) in the postintervention period had 12 doses in the discharge opioid prescription (differential change, 45.5 percentage points; 95% CI, 32.2-58.8 percentage points). Among pediatric otolaryngology patients, the mean (SD) number of doses prescribed in the preintervention period was 22.3 (7.4) and in the postintervention period was 16.1 (6.5) (differential percentage change, -29.2%; 95% CI, -43.2% to -11.7%). The intervention was not associated with changes in refills or pain-related visits. The secondary analysis included 150 patients. The intervention was not associated with changes in patient-reported outcomes except for a 3.5-point (95% CI, 1.5-5.5 points) differential increase in a sleep disturbance score that ranged from 4 to 20, with higher scores indicating poorer sleep quality. This nonrandomized clinical trial suggests that evidence-based default dosing settings may decrease perioperative opioid prescribing among adolescents and young adults undergoing tonsillectomy, without compromising analgesia.

Understanding the Natural History of Postoperative Pain and Patient-Reported Opioid Consumption After Elective Spine and Nerve Surgeries With an Automated Text Messaging System.

There is a gap in understanding how to ensure opioid stewardship while managing postoperative neurosurgical pain. To describe self-reported opioid consumption and pain intensity after common neurosurgery procedures gathered using an automated text messaging system. A prospective, observational study was performed at a large, urban academic health system in Pennsylvania. Adult patients (≥ 18 years), who underwent surgeries between October 2019 and May 2020, were consented. Data on postoperative pain intensity and patient-reported opioid consumption were collected prospectively for 3 months. We analyzed the association between the quantity of opioids prescribed and consumed. A total of 517 patients were enrolled. The median pain intensity at discharge was 5 out of a maximum of pain score of 10 and was highest after thoracolumbar fusion (median: 6, interquartile range [IQR]: 4-7). During the follow-up period, patients were prescribed a median of 40 tablets of 5-mg oxycodone equivalent pills (IQR: 28-40) and reported taking a median of 28 tablet equivalents (IQR: 17-40). Responders who were opioid-naive vs opioid-tolerant took a similar median number of opioid pills postoperatively (28 [IQR: 17-40] vs 27.5 [17.5-40], respectively). There was a statistically significant positive correlation between the quantity of opioids prescribed and used during the 3-month follow-up (Pearson R = 0.85, 95% CI [0.80-0.89], P < .001). The correlation was stronger among patients who were discharged to a higher level of care. Using real-time, patient-centered pain assessment and opioid consumption data will allow for the development of evidence-based opioid prescribing guidelines after spinal and nerve surgery.

Patient-Reported Opioid Consumption and Pain Intensity After Common Orthopedic and Urologic Surgical Procedures With Use of an Automated Text Messaging System

Surgeons must balance management of acute postoperative pain with opioid stewardship. Patient-centered methods that immediately evaluate pain and opioid consumption can be used to guide prescribing and shared decision-making. To assess the difference between the number of opioid tablets prescribed and the self-reported number of tablets taken as well as self-reported pain intensity and ability to manage pain after orthopedic and urologic procedures with use of an automated text messaging system. This quality improvement study was conducted at a large, urban academic health care system in Pennsylvania. Adult patients (aged ≥18 years) who underwent orthopedic and urologic procedures and received postoperative prescriptions for opioids were included. Data were collected prospectively using automated text messaging until postoperative day 28, from May 1 to December 31, 2019. The primary outcome was the difference between the number of opioid tablets prescribed and the patient-reported number of tablets taken (in oxycodone 5-mg tablet equivalents). Secondary outcomes were self-reported pain intensity (on a scale of 0-10, with 10 being the highest level of pain) and ability to manage pain (on a scale of 0-10, with 10 representing very able to control pain) after orthopedic and urologic procedures. Of the 919 study participants, 742 (80.7%) underwent orthopedic procedures and 177 (19.2%) underwent urologic procedures. Among those who underwent orthopedic procedures, 384 (51.8%) were women, 491 (66.7%) were White, and the median age was 48 years (interquartile range [IQR], 32-61 years); 514 (69.8%) had an outpatient procedure. Among those who underwent urologic procedures, 145 (84.8%) were men, 138 (80.7%) were White, and the median age was 56 years (IQR, 40-67 years); 106 (62%) had an outpatient procedure. The mean (SD) pain score on day 4 after orthopedic procedures was 4.72 (2.54), with a mean (SD) change by day 21 of -0.40 (1.91). The mean (SD) ability to manage pain score on day 4 was 7.32 (2.59), with a mean (SD) change of -0.80 (2.72) by day 21. The mean (SD) pain score on day 4 after urologic procedures was 3.48 (2.43), with a mean (SD) change by day 21 of -1.50 (2.12). The mean (SD) ability to manage pain score on day 4 was 7.34 (2.81), with a mean (SD) change of 0.80 (1.75) by day 14. The median quantity of opioids prescribed for patients who underwent orthopedic procedures was high compared with self-reported consumption (20 tablets [IQR, 15-30 tablets] vs 6 tablets used [IQR, 0-14 tablets]), similar to findings for patients who underwent urologic procedures (7 tablets [IQR, 5-10 tablets] vs 1 tablet used [IQR, 0-4 tablets]). Over the study period, 9452 of 15 581 total tablets prescribed (60.7%) were unused. A total of 589 patients (64.1%) used less than half of the amount prescribed, and 256 patients (27.8%) did not use any opioids (179 [24.1%] who underwent orthopedic procedures and 77 [43.5%] who underwent urologic procedures). In this quality improvement study of adult patients reporting use of opioids after common orthopedic and urologic surgical procedures through a text messaging system, the quantities of opioids prescribed and the quantity consumed differed. Patient-reported data collected through text messaging may support clinicians in tailoring prescriptions and guide shared decision-making to limit excess quantities of prescribed opioids.

Postdischarge Opioid Use after Lower Extremity Bypass Surgery

Opioid overprescription for acute postoperative pain is an inadvertent contributor to the opioid epidemic via pill diversion and misuse. In response, the surgical community advocates for evidence-based postoperative opioid prescribing guidelines. The objective of this study is to evaluate patient-reported opioid consumption after lower extremity bypass surgery. We conducted a retrospective review of a prospectively maintained database of infrainguinal bypass operations from 2016 to 2019. For patients receiving an opioid prescription at discharge, a telephone survey was administered questioning the percentage of pills used. Exclusion criteria included chronic opioid use and reoperations or amputations within 30days. The primary outcome was the difference in opioids prescribed versus opioids consumed. Forty-nine patients met inclusion criteria. Forty-one (84%) were prescribed opioids at discharge, and 27 (65.9%) completed the survey. The average age was 65.8±7.7years; 29.6% were women. Oxycodone immediate-release was most commonly prescribed (78%). On average, patients received 318±156 morphine milligram equivalent. A total of 940 opioid pills were prescribed (36.0±11.3 per patient), but only 37% were consumed. This difference resulted in 568 unused pills. This is the first study to specifically evaluate opioid use in a strictly lower extremity bypass population. Over 60% of pills were unused, which poses significant societal risk for misuse. Our findings contribute to knowledge of operation-specific opioid use, which may shape practice recommendations and reduce opioid overprescription after vascular surgery.

Opioid Consumption After Gender-Affirming Mastectomy and Two Other Breast Surgeries

BackgroundThere are few studies that evaluate patient-reported opioid consumption after discharge from surgery. In addition, there has been a call for “special care in prescribing opioids” for lesbian, gay, bisexual, transgender, questioning patients. Here, we evaluate if patients undergoing gender-affirming mastectomy (GAM) require different amounts of opioids for pain management after discharge compared alongside two surgeries with similar surgical exposure. Materials and methodsFrom October 2017 to July 2018, patients undergoing oncologic mastectomy without reconstruction, mammoplasty reduction, or gender-affirming mastectomy at a single institution were enrolled in a phone survey study to quantify opioids consumed after discharge from surgery. Patient information was captured from the medical record. A total of 170 patients were called between 14 and 30 d after discharge and were asked to count unused pills from their opioid prescription. ResultsA total of 99 patients participated and provided pill counts. There were differences between prescribed and consumed opioids within each surgery. Patients who underwent oncologic mastectomy were prescribed and consumed the lowest amounts of opioids. There were significantly more opioids prescribed to patients with GAM than mammoplasty reduction, but consumption was not statistically different. Patients with oncologic mastectomy, mammoplasty reduction, and GAM consumed a median of 0, 10, and 15 five mg oxycodone equivalent tablets, respectively. ConclusionsDespite similar approaches, surgeries had different opioid prescribing and use profiles. Generally, all patients were overprescribed opioids. Overprescribing may be especially problematic in patients with known higher risk of misuse and substance abuse. Granular data on patient consumption, demographics, and preoperative risk factors for opioid misuse may improve prescribing practices.

A retrospective cohort review of opioid prescribing and patient-reported consumption patterns following upper extremity surgery

Background: Across upper extremity procedures, patients are being prescribed approximately three times the opioid medication needed. The aim of this study was to evaluate opioid prescribing and consumption trends for patients undergoing various upper extremity surgeries at a regional medical center to further refine prescribing guidelines. Methods: A retrospective review of 152 patients undergoing shoulder, wrist, and forearm or hand surgery who completed a patient-reported opioid consumption tracking form between June 2017 and May 2018 was conducted. Opioid prescription and consumption data were converted into morphine milligram equivalents (MMEs). Results: Average total MME prescribed for the population was 147.5±130.1 MME and was significantly different across procedures (P&lt;0.001). Average MME taken across the cohort was 55.5±61.5 with significant differences across procedure types (P&lt;0.001). Controlling for gender and patient age, when compared with shoulder patients, patients undergoing wrist and forearm or hand procedures were significantly less likely to be overprescribed (OR=0.309, P=0.014; OR=0.225, P=0.001) and were overprescribed less MME on average (wrist and forearm β=−120.1, P&lt;0.001; hand β=−144.4, P&lt;0.001). There was no significant difference in the percentage of patients requiring second opioid fills, with an average refill rate of 14.5% across the cohort (P=0.116). Conclusions: Significant differences in the need for opioid analgesia exist across upper extremity procedures, with shoulder surgery patients being overprescribed most frequently and by the highest MMEs. Due to the variability in narcotic utilization, patient-specific factors must be considered by providers when determining optimal opioid prescribing levels. Level of Evidence: Level IV.

Opioid Prescribing and Use in Ambulatory Otolaryngology.

The objective of this study was to evaluate surgeon-prescribing patterns and opioid use for patients undergoing common otolaryngology surgeries. We hypothesized that there was little consistency across surgeons in prescribing patterns and that surgeons prescribed significantly more opioids than consumed by patients. E-mail-based surveys were sent to all postoperative patients across a 23-hospital system. The survey assessed quantity of opioids consumed postoperatively, patient-reported pain control, and methods of opioid disposal. We compared patient-reported opioid consumption to opioids prescribed based on data in the electronic data warehouse. There was wide variation in prescribing between providers both in the quantity and type of opioids prescribed. Patients used significantly less opioids than they were prescribed (10 vs. 30 tablets, P < 0.001) for both opioid-exposed and opioid-naïve patients. More than 75% of patients had excess opioids remaining. Opioids are consistently overprescribed following ambulatory head and neck surgery. Otolaryngologists have an important role in the setting of the national opioid epidemic and should be involved in efforts to reduce excess opioids in their community. 4 Laryngoscope, 130: 1913-1921, 2020.

A Novel Mobile Phone Text Messaging Platform Improves Collection of Patient-Reported Post-operative Pain and Opioid Use Following Orthopedic Surgery.

Prospective collection of patient-reported opioid consumption and pain levels post-surgically may hold value in highlighting solutions related to the opioid crisis. Traditional methods for collecting patient-reported outcomes after surgery, such as paper surveys, often have poor response rates, and electronic messaging may offer more convenience and therefore yield more robust data. The purpose of this study was to evaluate whether a novel mobile phone short message service (SMS) platform would lead to better patient response rates to surveys on pain and opioid use than data-collection tools. An SMS text messaging platform was created and implemented between September 2017 and May 2018 at an orthopedic specialty hospital. The purpose was to collect reports on opioid consumption and pain levels twice a day for 6weeks post-surgery from patients who had undergone total hip or knee arthroplasty or a single-level lumbar microdiscectomy or decompression spine surgery. Patients who responded to fewer than 50% of the text messages were excluded. Our mobile phone text messaging platform was used by 183 patients, demonstrating a significantly higher response rate (96.1%) than our institution's post-operative email registry capture, as well as the majority of published response rates for post-operative outcomes captured through electronic and traditional data-collection systems. Response rate remained consistently high among the various surgeons and across patients, regardless of age. This application of a widely available technology can improve the measurement of post-operative patient-reported outcomes. Such data can in turn be used in the development of strategies to reduce post-operative opioid use. The adoption of novel technologies at a patient level will play a key role in combating the opioid epidemic.

Association of Opioid Prescribing With Opioid Consumption After Surgery in Michigan

There is growing evidence that opioids are overprescribed following surgery. Improving prescribing requires understanding factors associated with opioid consumption. To describe opioid prescribing and consumption for a variety of surgical procedures and determine factors associated with opioid consumption after surgery. A retrospective, population-based analysis of the quantity of opioids prescribed and patient-reported opioid consumption across 33 health systems in Michigan, using a sample of adults 18 years and older undergoing surgery. Patients were included if they were prescribed an opioid after surgery. Surgical procedures took place between January 1, 2017, and September 30, 2017, and were included if they were performed in at least 25 patients. Opioid prescription size in the initial postoperative prescription. Patient-reported opioid consumption in oral morphine equivalents. Linear regression analysis was used to calculate risk-adjusted opioid consumption with robust standard errors. In this study, 2392 patients (mean age, 55 years; 1353 women [57%]) underwent 1 of 12 surgical procedures. Overall, the quantity of opioid prescribed was significantly higher than patient-reported opioid consumption (median, 30 pills; IQR, 27-45 pills of hydrocodone/acetaminophen, 5/325 mg, vs 9 pills; IQR, 1-25 pills; P < .001). The quantity of opioid prescribed had the strongest association with patient-reported opioid consumption, with patients using 0.53 more pills (95% CI, 0.40-0.65; P < .001) for every additional pill prescribed. Patient-reported pain in the week after surgery was also significantly associated with consumption but not as strongly as prescription size. Compared with patients reporting no pain, patients used a mean (SD) 9 (1) more pills if they reported moderate pain and 16 (2) more pills if they reported severe pain (P < .001). Other significant risk factors included history of tobacco use, American Society of Anesthesiologists class, age, procedure type, and inpatient surgery status. After adjusting for these risk factors, patients in the lowest quintile of opioid prescribing had significantly lower mean (SD) opioid consumption compared with those in the highest quintile (5 [2] pills vs 37 [3] pills; P < .001). The quantity of opioid prescribed is associated with higher patient-reported opioid consumption. Using patient-reported opioid consumption to develop better prescribing practices is an important step in combating the opioid epidemic.
