Medicaid Insurance Predicts Increased Postoperative Care Encounters Among Patients on Long-Term Opioid Therapy

OBJECTIVE

This study examined the association between insurance type and postoperative unplanned care encounters among patients on long-term opioid therapy prior to surgery.

SUMMARY BACKGROUND DATA

Preoperative long-term opioid therapy is associated with unique risks and poorer outcomes following surgery. To date, the extent to which insurance coverage influences postoperative outcomes in this population remains unclear.

METHODS

Among individuals receiving a supply of greater than 120 total days or at least 10 opioid prescriptions in the year prior to surgery, we examined patients with Medicaid or private insurance who underwent abdominopelvic surgery from 2017 to 2021 across 70 hospitals in the state of Michigan. The primary outcome was unplanned care encounters, defined as an emergency department visit or unplanned readmission within 30 days of discharge from surgery. Multivariable logistic regression was used to assess the likelihood of acute care events with insurance type as the primary covariate of interest.

RESULTS

Among 1212 patients on long-term opioid therapy prior to surgery, 45.6% (n = 553) had Medicaid insurance. Overall, one in eight (n=151) patients met criteria for a postoperative unplanned care encounter within 30 days. The probability of an unplanned encounter was 4.5 percentage points higher among patients with Medicaid insurance compared to private insurance (95% CI: 0.5%, 8.4%).

CONCLUSIONS

Among patients on preoperative long-term opioid therapy, unplanned care encounters were higher among patients with Medicaid when compared to private insurance. While this is likely multifactorial, differences by insurance status may point to disparities in underlying social determinants of health and suggest the need for postoperative care pathways that address these gaps.

The Association of Preoperative Opioid Use with Post-Discharge Outcomes: A Cohort Study of the Michigan Surgical Quality Collaborative

OBJECTIVE

To examine the association of prescription opioid fills over the year prior to surgery with postoperative outcomes.

BACKGROUND

Nearly one third of patients report opioid use in the year preceding surgery, yet an understanding of how opioid exposure influences patient-reported outcomes after surgery remains incomplete. Therefore, this study was designed to test the hypothesis that preoperative opioid exposure may impede recovery in the postoperative period.

METHODS

This retrospective cohort study used a statewide clinical registry from 70 hospitals linked to opioid fulfillment data from the state's prescription drug monitoring program to categorize patients' preoperative opioid exposure as none (naïve), minimal, intermittent, or chronic. Outcomes were patient-reported pain intensity (primary), as well as 30-day clinical and patient-reported outcomes (secondary).

RESULTS

Compared to opioid-naïve patients, opioid exposure was associated with higher reported pain scores at 30 days after surgery. Predicted probabilities was higher among the opioid exposed versus naive group for reporting moderate pain (43.5% [95% CI 42.6 - 44.4%] vs 39.3% [95% CI 38.5 - 40.1%]) and severe pain (13.% [95% CI 12.5 - 14.0%] vs 10.0% [95% CI 9.5 - 10.5%]), and increasing probability was associated increased opioid exposure for both outcomes. Clinical outcomes (incidence of ED visits, readmissions, and reoperation within 30-days) and patient-reported outcomes (reported satisfaction, regret, and quality of life) were also worse with increasing preoperative opioid exposure for most outcomes.

CONCLUSIONS

This study is the first to examine the effect of presurgical opioid exposure on both clinical and non-clinical outcomes in a broad cohort of patients, and shows that exposure is associated with worse postsurgical outcomes. A key question to be addressed is whether and to what extent opioid tapering before surgery mitigates these risks after surgery.

Peer Comparison or Guideline-Based Feedback and Postsurgery Opioid Prescriptions: A Randomized Clinical Trial

Importance

Excess opioid prescribing after surgery can result in prolonged use and diversion. Email feedback based on social norms may reduce the number of pills prescribed.

Objective

To assess the effectiveness of 2 social norm-based interventions on reducing guideline-discordant opioid prescribing after surgery.

Design, Setting, and Participants

This cluster randomized clinical trial conducted at a large health care delivery system in northern California between October 2021 and October 2022 included general, obstetric/gynecologic, and orthopedic surgeons with patients aged 18 years or older discharged to home with an oral opioid prescription.

Interventions

In 19 hospitals, 3 surgical specialties (general, orthopedic, and obstetric/gynecologic) were randomly assigned to a control group or 1 of 2 interventions. The guidelines intervention provided email feedback to surgeons on opioid prescribing relative to institutionally endorsed guidelines; the peer comparison intervention provided email feedback on opioid prescribing relative to that of peer surgeons. Emails were sent to surgeons with at least 2 guideline-discordant prescriptions in the previous month. The control group had no intervention.

Main Outcome and Measures

The probability that a discharged patient was prescribed a quantity of opioids above the guideline for the respective procedure during the 12 intervention months.

Results

There were 38 235 patients discharged from 640 surgeons during the 12-month intervention period. Control-group surgeons prescribed above guidelines 36.8% of the time during the intervention period compared with 27.5% and 25.4% among surgeons in the peer comparison and guidelines arms, respectively. In adjusted models, the peer comparison intervention reduced guideline-discordant prescribing by 5.8 percentage points (95% CI, -10.5 to -1.1; P = .03) and the guidelines intervention reduced it by 4.7 percentage points (95% CI, -9.4 to -0.1; P = .05). Effects were driven by surgeons who performed more surgeries and had more guideline-discordant prescribing at baseline. There was no significant difference between interventions.

Conclusions and Relevance

In this cluster randomized clinical trial, email feedback based on either guidelines or peer comparison reduced opioid prescribing after surgery. Guideline-based feedback was as effective as peer comparison-based feedback. These interventions are simple, low-cost, and scalable, and may reduce downstream opioid misuse.

Drivers of variation in postpartum opioid prescribing across hospitals participating in a statewide maternity care quality collaborative

BACKGROUND

We describe variation in postpartum opioid prescribing across a statewide quality collaborative and assess the proportion due to practitioner and hospital characteristics.

METHODS

We assessed postpartum prescribing data from nulliparous, term, singleton, vertex births between January 2020 and June 2021 included in the clinical registry of a statewide obstetric quality collaborative funded by Blue Cross Blue Shield of Michigan. Data were summarized using descriptive statistics. Mixed effect logistic regression and linear models adjusted for patient characteristics and assessed practitioner- and hospital-level predictors of receiving a postpartum opioid prescription and prescription size. Relative contributions of practitioner and hospital characteristics were assessed using the intraclass correlation coefficient.

RESULTS

Of 40,589 patients birthing at 68 hospitals, 3.0% (872/29,412) received an opioid prescription after vaginal birth and 87.8% (9812/11,177) received one after cesarean birth, with high variation across hospitals. In adjusted models, the strongest patient-level predictors of receiving a prescription were cesarean birth (aOR 899.1, 95% CI 752.8-1066.7) and third-/fourth-degree perineal laceration (aOR 25.7, 95% CI 17.4-37.9). Receiving care from a certified nurse-midwife (aOR 0.63, 95% CI 0.48-0.82) or family medicine physician (aOR 0.60, 95%CI 0.39-0.91) was associated with lower prescribing rates. Hospital-level predictors included receiving care at hospitals with <500 annual births (aOR 4.07, 95% CI 1.61-15.0). A positive safety culture was associated with lower prescribing rates (aOR 0.37, 95% CI 0.15-0.88). Much of the variation in postpartum prescribing was attributable to practitioners and hospitals (prescription receipt: practitioners 25.1%, hospitals 12.1%; prescription size: practitioners 5.4%, hospitals: 52.2%).

DISCUSSION

Variation in postpartum opioid prescribing after birth is high and driven largely by practitioner- and hospital-level factors. Opioid stewardship efforts targeted at both the practitioner and hospital level may be effective for reducing opioid prescribing harms.

High-risk Prescribing Following Surgery Among Payer Types for Patients on Chronic Opioids

OBJECTIVE

Among those on chronic opioids, to determine whether patients with Medicaid coverage have higher rates of high-risk opioid prescribing following surgery compared with patients on private insurance.

BACKGROUND

Following surgery, patients on chronic opioids experience gaps in transitions of care back to their usual opioid prescriber, but differences by payer type are not well understood. This study aimed to analyze how new high-risk opioid prescribing following surgery compares between Medicaid and private insurance.

METHODS

In this retrospective cohort study through the Michigan Surgical Quality Collaborative, perioperative data from 70 hospitals across Michigan were linked to prescription drug monitoring program data. Patients with either Medicaid or private insurance were compared. The outcome of interest was new high-risk prescribing, defined as a new occurrence of: overlapping opioids or benzodiazepines, multiple prescribers, high daily doses, or long-acting opioids. Data were analyzed using multivariable regressions and a Cox regression model for return to usual prescriber.

RESULTS

Among 1435 patients, 23.6% (95% CI: 20.3%-26.8%) with Medicaid and 22.7% (95% CI: 19.8%-25.6%) with private insurance experienced new, postoperative high-risk prescribing. New multiple prescribers was the greatest contributing factor for both payer types. Medicaid insurance was not associated with higher odds of high-risk prescribing (odds ratio: 1.067, 95% CI: 0.813-1.402).

CONCLUSIONS

Among patients on chronic opioids, new high-risk prescribing following surgery was high across payer types. This highlights the need for future policies to curb high-risk prescribing patterns, particularly in vulnerable populations that are at risk of greater morbidity and mortality.

Association Between Payer Type and Risk of Persistent Opioid Use After Surgery

OBJECTIVE

To assess whether the risk of persistent opioid use after surgery varies by payer type.

BACKGROUND

Persistent opioid use is associated with increased health care utilization and risk of opioid use disorder, opioid overdose, and mortality. Most research assessing the risk of persistent opioid use has focused on privately insured patients. Whether this risk varies by payer type is poorly understood.

METHODS

This cross-sectional analysis of the Michigan Surgical Quality Collaborative database examined adults aged 18 to 64 years undergoing surgical procedures across 70 hospitals between January 1, 2017 and October 31, 2019. The primary outcome was persistent opioid use, defined a priori as 1+ opioid prescription fulfillment at (1) an additional opioid prescription fulfillment after an initial postoperative fulfillment in the perioperative period or at least 1 fulfillment in the 4 to 90 days after discharge and (2) at least 1 opioid prescription fulfillment in the 91 to 180 days after discharge. The association between this outcome and payer type was evaluated using logistic regression, adjusting for patient and procedure characteristics.

RESULTS

Among 40,071 patients included, the mean age was 45.3 years (SD 12.3), 24,853 (62%) were female, 9430 (23.5%) were Medicaid-insured, 26,760 (66.8%) were privately insured, and 3889 (9.7%) were covered by other payer types. The rate of POU was 11.5% and 5.6% for Medicaid-insured and privately insured patients, respectively (average marginal effect for Medicaid: 2.9% (95% CI 2.3%-3.6%)).

CONCLUSIONS

Persistent opioid use remains common among individuals undergoing surgery and higher among patients with Medicaid insurance. Strategies to optimize postoperative recovery should focus on adequate pain management for all patients and consider tailored pathways for those at risk.

Predicting chronic postsurgical pain: current evidence and a novel program to develop predictive biomarker signatures

ABSTRACT

Chronic pain affects more than 50 million Americans. Treatments remain inadequate, in large part, because the pathophysiological mechanisms underlying the development of chronic pain remain poorly understood. Pain biomarkers could potentially identify and measure biological pathways and phenotypical expressions that are altered by pain, provide insight into biological treatment targets, and help identify at-risk patients who might benefit from early intervention. Biomarkers are used to diagnose, track, and treat other diseases, but no validated clinical biomarkers exist yet for chronic pain. To address this problem, the National Institutes of Health Common Fund launched the Acute to Chronic Pain Signatures (A2CPS) program to evaluate candidate biomarkers, develop them into biosignatures, and discover novel biomarkers for chronification of pain after surgery. This article discusses candidate biomarkers identified by A2CPS for evaluation, including genomic, proteomic, metabolomic, lipidomic, neuroimaging, psychophysical, psychological, and behavioral measures. Acute to Chronic Pain Signatures will provide the most comprehensive investigation of biomarkers for the transition to chronic postsurgical pain undertaken to date. Data and analytic resources generatedby A2CPS will be shared with the scientific community in hopes that other investigators will extract valuable insights beyond A2CPS's initial findings. This article will review the identified biomarkers and rationale for including them, the current state of the science on biomarkers of the transition from acute to chronic pain, gaps in the literature, and how A2CPS will address these gaps.

The Association of Cognitive Status and Post-Operative Opioid Prescribing in Older Adults

Objective

To examine the differences in opioid prescribing by cognitive status following common elective surgical procedures among Medicare beneficiaries.

Background

Older individuals commonly experience changes in cognition with age. Although opioid prescribing is common after surgery, differences in opioid prescribing after surgery by cognitive status are poorly understood.

Methods

We conducted a retrospective analysis of patients ≥65 years participating in the Health and Retirement Study (HRS) linked with Medicare claims data who underwent surgeries between January 2007 and November 2016 and had cognitive assessments before the index operation. Cognitive status was defined as normal cognition, mild cognitive impairment (MCI), or dementia. Outcomes assessed were initial perioperative opioid fill rates, refill rates, and high-risk prescriptions fill rates. The total amount of opioids filled during the 30-day postdischarge period was also assessed. Adjusted rates were estimated for patient factors using the Cochran-Armitage test for trend.

Results

Among the 1874 patients included in the analysis, 68% had normal cognition, 21.3% had MCI, and 10.7% had dementia. Patients with normal cognition (58.1%) and MCI (54.5%) had higher initial preoperative fill rates than patients with dementia (33.5%) (P < 0.001). Overall, patients with dementia had similar opioid refill rates (21%) to patients with normal cognition (24.1%) and MCI (26.5%) (P = 0.322). Although prior opioid exposure did not differ by cognitive status (P = 0.171), among patients with high chronic preoperative use, those with dementia had lower adjusted prescription sizes filled within 30 days following discharge (281 OME) than patients with normal cognition (2147 OME) and MCI (774 OME) (P < 0.001; P = 0.009 respectively). Among opioid-naive patients, patients with dementia also filled smaller prescription sizes (97 OME) compared to patients with normal cognition (205 OME) and patients with MCI (173 OME) (P < 0.001 and P = 0.019, respectively).

Conclusions

Patients with dementia are less likely to receive postoperative prescriptions, less likely to refill prescriptions, and receive prescriptions of smaller sizes compared to patients with normal cognition or MCI. A cognitive assessment is an additional tool surgeons can use to determine a patient's individualized postoperative pain control plan.

Evidence-Based Opioid Prescribing Guidelines and New Persistent Opioid Use After Surgery

OBJECTIVE

Evaluate the association of evidence-based opioid prescribing guidelines with new persistent opioid use after surgery.

SUMMARY BACKGROUND DATA

Patients exposed to opioids after surgery are at risk of new persistent opioid use, which is associated with opioid use disorder and overdose. It is unknown whether evidence-based opioid prescribing guidelines mitigate this risk.

METHODS

Using Medicare claims, we performed a difference-in-differences study of opioid-naive patients who underwent 1 of 6 common surgical procedures for which evidence-based postoperative opioid prescribing guidelines were released and disseminated through a statewide quality collaborative in Michigan in October 2017. The primary outcome was the incidence of new persistent opioid use, and the secondary outcome was total postoperative opioid prescription quantity in oral morphine equivalents (OME).

RESULTS

We identified 24,908 patients who underwent surgery in Michigan and 118,665 patients who underwent surgery outside of Michigan. Following the release of prescribing guidelines in Michigan, the adjusted incidence of new persistent opioid use decreased from 3.29% (95% CI 3.15-3.43%) to 2.51% (95% CI 2.35-2.67%) in Michigan, which was an additional 0.53 (95% CI 0.36-0.69) percentage point decrease compared with patients outside of Michigan. Simultaneously, adjusted opioid prescription quantity decreased from 199.5 (95% CI 198.3-200.6) mg OME to 88.6 (95% CI 78.7-98.5) mg OME in Michigan, which was an additional 55.7 (95% CI 46.5-65.4) mg OME decrease compared with patients outside of Michigan.

CONCLUSIONS

Evidence-based opioid prescribing guidelines were associated with a significant reduction in the incidence of new persistent opioid use and the quantity of opioids prescribed after surgery.

Racial and Ethnic Differences in Elective Versus Emergency Surgery for Colorectal Cancer

OBJECTIVE

To evaluate differences in presentation and outcomes of surgery for colorectal cancer.

BACKGROUND

Although racial and socioeconomic disparities in colorectal cancer outcomes are well documented, disparities in access affecting disease presentation are less clear.

METHODS

We conducted a statewide retrospective study of patients who underwent resection for colorectal cancer between January 1, 2015, and April 30, 2021. The primary outcome was undergoing emergency surgery. Secondary outcomes included preoperative evaluation and postoperative outcomes. Covariates of interest included race/ethnicity, social deprivation index, and insurance type.

RESULTS

A total of 4869 patients underwent surgery for colorectal cancer, of whom 1122 (23.0%) underwent emergency surgery. Overall, 28.1% of Black non-Hispanic patients and 22.5% of White non-Hispanic patients underwent emergency surgery. On multivariable logistic regression, Black non-Hispanic race was independently associated with a 5.8 (95% CI, 0.3-11.3) percentage point increased risk of emergency surgery compared with White non-Hispanic race. Patients who underwent emergency surgery were significantly less likely to have preoperative carcinoembryonic antigen measurement, staging for rectal cancer, and wound/ostomy consultation. Patients who underwent emergency surgery had a higher incidence of 30-day mortality (5.5% vs 1.0%, P <0.001), positive surgical margins (11.1% vs 4.9%, P <0.001), complications (29.2% vs 16.0%, P <0.001), readmissions (12.5% vs 9.6%, P =0.005), and reoperations (12.2% vs 8.2%, P <0.001).

CONCLUSIONS

Among patients with colorectal cancer, Black non-Hispanic patients were more likely to undergo emergency surgery than White non-Hispanic patients, suggesting they may face barriers to timely screening and evaluation. Undergoing emergency surgery was associated with incomplete oncologic evaluation, increased incidence of postoperative complications including mortality, and increased surgical margin positivity. These results suggest that racial and ethnic differences in the diagnosis and treatment of colorectal cancer impact near-term and long-term outcomes.

Use of Opioid-Sparing Protocols and Perceived Postpartum Pain in Patients with Opioid Use Disorder and Chronic Prenatal Opioid Exposure

INTRODUCTION

Opioid-sparing protocols reduce postpartum opioid prescribing in opioid-naïve patients; however, patients with opioid use disorder (OUD) and complex pain needs who may benefit from these protocols are typically excluded from them. We assessed postpartum pain experiences of patients with OUD and chronic prenatal opioid exposure after implementation of an opioid-sparing protocol.

METHODS

A phone survey assessed postpartum pain experiences for people with chronic prenatal opioid exposure who delivered between January 2020 and August 2021 at an academic hospital. Analyses included descriptive statistics, qualitative content analysis, and a joint display comparing themes.

RESULTS

Of 25 patients, 18 (72%) participated; most were non-Hispanic White (100%, 18/18), publicly insured (78%, 14/18), multiparous (78%, 14/18), with OUD (100%, 18/18). No patients with a vaginal birth received an opioid prescription; half (4/8) with a cesarean birth received one at discharge. Over one-third (7/18, 39%) reported poor pain control (≥ 5/10) in the hospital and one week post-discharge; scores were higher for cesarean versus vaginal birth. Qualitative sub-analyses of open-ended responses revealed patient perceptions of postpartum pain and treatment. The most effective strategies, stratified by birth type and pain level, ranged from non-opioid medications for vaginal births and minor pain to prescription opioids for cesarean births and moderate-to-intense pain.

DISCUSSION

Postpartum opioid prescribing for patients with chronic prenatal opioid use was low for vaginal and cesarean birth following implementation of an opioid-sparing protocol. Patients with OUD reported good pain management with opioid-sparing pain regimens; however, many reported poorly controlled pain immediately postpartum. Future work should assess approaches to postpartum pain management that minimize the risks of opioid medication-particularly in at-risk groups.

Postoperative Opioid Prescribing and New Persistent Opioid Use: The Risk of Excessive Prescribing

OBJECTIVE

Evaluate the association between postoperative opioid prescribing and new persistent opioid use.

SUMMARY BACKGROUND DATA

Opioid-nave patients who develop new persistent opioid use after surgery are at increased risk of opioid-related morbidity and mortality. However, the extent to which postoperative opioid prescribing is associated with persistent postoperative opioid use is unclear.

METHODS

Retrospective study of opioid-naïve adults undergoing surgery in Michigan from 1/1/2017 to 10/31/2019. Postoperative opioid prescriptions were identified using a statewide clinical registry and prescription fills were identified using Michigan's prescription drug monitoring program. The primary outcome was new persistent opioid use, defined as filling at least 1 opioid prescription between post-discharge days 4 to 90 and filling at least 1 opioid prescription between post-discharge days 91 to 180.

RESULTS

A total of 37,654 patients underwent surgery with a mean age of 52.2 (16.7) years and 20,923 (55.6%) female patients. A total of 31,920 (84.8%) patients were prescribed opioids at discharge. Six hundred twenty-two (1.7%) patients developed new persistent opioid use after surgery. Being prescribed an opioid at discharge was not associated with new persistent opioid use [adjusted odds ratio (aOR) 0.88 (95% confidence interval (CI) 0.71-1.09)]. However, among patients prescribed an opioid, patients prescribed the second largest [12 (interquartile range (IQR) 3) pills] and largest [20 (IQR 7) pills] quartiles of prescription size had higher odds of new persistent opioid use compared to patients prescribed the smallest quartile [7 (IQR 1) pills] of prescription size [aOR 1.39 (95% CI 1.04-1.86) andaOR 1.97 (95% CI 1.442.70), respectively].

CONCLUSIONS

In a cohort of opioid-naïve patients undergoing common surgical procedures, the risk of new persistent opioid use increased with the size of the prescription. This suggests that while opioid prescriptions in and of themselves may not place patients at risk of long-term opioid use, excessive prescribing does. Consequently, these findings support ongoing efforts to mitigate excessive opioid prescribing after surgery to reduce opioid-related harms.

"I Prefer to Stay Away": A Qualitative Study of Patients in an Opioid-Sparing Pain Management Protocol

OBJECTIVE

The aim of this study was to explore beliefs and behaviors of opioid pain medications among patients undergoing elective surgery.

BACKGROUND

Opioid dependence after surgery is a major contributor to the ongoing opioid epidemic. Recent efforts by surgeons and health systems have sought to improve the education patients receive regarding safe opioid use after surgery; however, little is known about patients' pre-existing beliefs surrounding opioids.

METHODS

Semistructured interviews were conducted with patients who underwent 1 of 4 common elective surgical procedures at 1 institution. Patients were specifically asked about their knowledge and beliefs about opioids before surgery and their opinions of opioid-sparing recovery after surgery. Coding was conducted through iterative steps, beginning with an initial cycle of rapid analysis, followed by focused coding, and thematic analysis.

RESULTS

Twenty-one patients were interviewed. Three major themes emerged regarding patient opinions about using opioids after surgery. First, there was widespread awareness among patients about opioid medications, and preoperatively, patients had specific intentions about using opioids, often informed by this awareness. Second, patients described a spectrum of opioid related behavior which both aligned and conflicted with preoperative intentions. Third, there was tension among patients about opioid-free postoperative recovery, with patients expressing support, opposition, and emphasis on tailoring recovery to patient needs.

CONCLUSIONS

Patients undergoing common surgical procedures often arrive at their surgical encounter with strong, pre-formed opinions about opioids. Eliciting these preexisting opinions may help surgeons better counsel patients about safe opioid use after surgery.

The Influence of Cognitive Impairment on Postoperative Outcomes

OBJECTIVE

To examine differences in rates of elective surgery, postoperative mortality, and readmission by pre-existing cognitive status among Medicare beneficiaries undergoing surgery.

BACKGROUND

MCI is common among older adults, but the impact of MCI on surgical outcomes is understudied.

METHODS

We conducted a retrospective cohort study of individuals ≥65 who underwent surgery between 2001 and 2015 using data from the nationally-representative Health and Retirement Study linked with Medicare claims. Cognitive status was assessed by the modified telephone interview for cognitive status score and categorized as normal cognition (score: 12-27), MCI (7-11), and dementia (<7). Outcomes were 30- and 90-day postoperative mortality and readmissions. We used Cox proportional hazard models to estimate the risk of each outcome by cognition, adjusting for patient characteristics.

RESULTS

In 6,590 patients, 69.9% had normal cognition, 20.1% had MCI, and 9.9% had dementia. Patients with MCI (79.9%) and dementia (73.6%) were less likely to undergo elective surgery than patients with normal cognition (85.9%). Patients with MCI had similar postoperative mortality and readmissions rates as patients with normal cognition. However, patients with dementia had significantly higher postoperative 90-day mortality (5.2% vs 8.4%, P = 0.002) and readmission rates (13.9% vs 17.3%, P = 0.038).

CONCLUSION

Patients with self-reported MCI are less likely to undergo elective surgery but have similar postoperative outcomes compared with patients with normal cognition. Despite the variability of defining MCI, our findings suggest that MCI may not confer additional risk for older individuals undergoing surgery, and should not be a barrier for surgical care.

Factors that influence discharge opioid prescribing among bariatric surgeons across Michigan

BACKGROUND

Opioid prescribing following bariatric surgery has been a focus due to its association with new persistent opioid use (NPOU) and worse outcomes. Guidelines have led to a reduction in opioids prescribed, but there remains variation in prescribing practices.

METHODS

We conducted interviews with 20 bariatric surgeons across Michigan. Transcripts were analyzed using descriptive content analysis.

RESULTS

At the patient level, surgeons described the role of surgical history and pain tolerance. At the provider level, surgeons discussed patient dissatisfaction, reputation, and workload. At the institution level, surgeons discussed colleagues, resources, and administration. At a collaborative level, surgeons described the role of evidence and performance measures. There was lack of consensus on whether NPOU is a problem facing patients undergoing bariatric surgery.

CONCLUSION

Despite efforts aimed at addressing opioid prescribing, variability exists in prescribing practices. Understanding determinants that impact stakeholder alignment is critical to increasing adherence to guideline-concordant care.

The Association of Postoperative Opioid Prescriptions with Patient Outcomes

OBJECTIVE

To compare outcomes after surgery between patients who were not prescribed opioids and patients who were prescribed opioids.

SUMMARY OF BACKGROUND DATA

Postoperative opioid prescriptions carry significant risks. Understanding outcomes among patients who receive no opioids after surgery may inform efforts to reduce these risks.

METHODS

We performed a retrospective study of adult patients who underwent surgery between January 1, 2019 and October 31, 2019. The primary outcome was the composite incidence of an emergency department visit, readmission, or reoperation within 30 days of surgery. Secondary outcomes were postoperative pain, satisfaction, quality of life, and regret collected via postoperative survey. A multilevel, mixed-effects logistic regression was performed to evaluate differences between groups.

RESULTS

In a cohort of 22,345 patients, mean age (standard deviation) was 52.1 (16.5) years and 13,269 (59.4%) patients were female. About 3175 (14.2%) patients were not prescribed opioids, of whom 422 (13.3%) met the composite adverse event endpoint compared to 2255 (11.8%) of patients not prescribed opioids ( P = 0.015). Patients not prescribed opioids had a similar probability of adverse events {11.7% [95% confidence interval (CI) 10.2%-13.2%] vs 11.9% (95% CI 10.6%-13.3%]}. Among 12,872 survey respondents, patients who were not prescribed an opioid had a similar rate of high satisfaction [81.7% (95% CI 77.3%-86.1%) vs 81.7% (95% CI 77.7%- 85.7%)] and no regret [(93.0% (95% CI 90.8%-95.2%) vs 92.6% (95% CI 90.4%-94.7%)].

CONCLUSIONS

Patients who were not prescribed opioids after surgery had similar clinical and patient-reported outcomes as patients who were prescribed opioids. This suggests that minimizing opioids as part of routine postoperative care is unlikely to adversely affect patients.

New Persistent Opioid Use After Inguinal Hernia Repair

OBJECTIVE

To describe the incidence of new persistent opioid use after inguinal hernia repair as well as its associated risk factors.

SUMMARY OF BACKGROUND DATA

The development of new persistent opioid use after surgery is a common complication; however, its incidence following inguinal hernia repair has not been described. Given that roughly 800,000 inguinal hernia repairs are performed annually in the USA, any incidence could have profound implications for patients.

METHODS

A retrospective cross-sectional study of the incidence of new persistent opioid use after inguinal hernia repair using a national database of de-identified administrative health claims of opioid-naïve patients undergoing surgery from 2008 to 2016.

RESULTS

During the study period, 59,795 opioid-naïve patients underwent inguinal hernia repair and met inclusion criteria. Mean (SD) age was 57.8 (16.1) years and 55,014 (92%) patients were male. Nine hundred twenty-two (1.5%) patients continued filling opioids prescriptions for at least 3 months after surgery. The most significant risk factor for developing new persistent opioid use after surgery was filling an opioid prescription in the 30 days before surgery (odds ratio 4.34, 95% confidence interval 3.75-5.01). These prescriptions were provided by surgeons in 52% of cases and primary care physicians in 16% of cases. Other risk factors for new persistent opioid use included receiving a larger opioid prescription, having more comorbidities, having a major postoperative complication, and certain mental health disorders and pain disorders.

CONCLUSIONS

After undergoing inguinal hernia repair, 1.5% of patients developed new persistent opioid use. Filling an opioid prescription in the 30 days before surgery had the strongest association with this complication.

Multi-Site Observational Study to Assess Biomarkers for Susceptibility or Resilience to Chronic Pain: The Acute to Chronic Pain Signatures (A2CPS) Study Protocol

Chronic pain has become a global health problem contributing to years lived with disability and reduced quality of life. Advances in the clinical management of chronic pain have been limited due to incomplete understanding of the multiple risk factors and molecular mechanisms that contribute to the development of chronic pain. The Acute to Chronic Pain Signatures (A2CPS) Program aims to characterize the predictive nature of biomarkers (brain imaging, high-throughput molecular screening techniques, or "omics," quantitative sensory testing, patient-reported outcome assessments and functional assessments) to identify individuals who will develop chronic pain following surgical intervention. The A2CPS is a multisite observational study investigating biomarkers and collective biosignatures (a combination of several individual biomarkers) that predict susceptibility or resilience to the development of chronic pain following knee arthroplasty and thoracic surgery. This manuscript provides an overview of data collection methods and procedures designed to standardize data collection across multiple clinical sites and institutions. Pain-related biomarkers are evaluated before surgery and up to 3 months after surgery for use as predictors of patient reported outcomes 6 months after surgery. The dataset from this prospective observational study will be available for researchers internal and external to the A2CPS Consortium to advance understanding of the transition from acute to chronic postsurgical pain.

Opioid Prescribing Habits and Pain Management Among Aesthetic Plastic Surgeons

BACKGROUND

The opioid epidemic continues to worsen in the USA. Post-operative opioid prescriptions contribute to development of opioid use disorders, with studies showing 6% of plastic surgery patients developing new persistent use. Prescribing by surgeons is often excessive, and plastic surgery patients only consume about half of their opioid prescriptions. To date, most studies that investigate post-operative opioid prescribing rely on examining patterns of opioid fills after surgery using administrative claims data, which exclude the overwhelming majority of aesthetic surgeries. The purpose of this study is to investigate opioid prescribing habits amongst aesthetic plastic surgeons.

METHODS

A 20-items survey were sent out to the Aesthetic Society. The survey focussed on general pain management techniques, as well as specific opioid prescribing patterns for several common aesthetic surgeries.

RESULTS

A total of 291 completed surveys were returned. Respondents were asked about opioid prescribing patterns for several common aesthetic surgeries. Surgeons were most likely to prescribe opioids for post-operative pain control for abdominoplasty (91%). Opioids were least likely to be prescribed for blepharoplasty (58%). For studied surgeries, the number of pills prescribed ranged from 2 to 120 pills per procedure. 45% of respondents reported being concerned that the opioid prescriptions they provide contribute to the development of an opioid use disorder.

CONCLUSIONS

Aesthetic plastic surgeons vary widely in their opioid prescribing. Additionally, a significant number are concerned that prescriptions they provide contribute to development of opioid use disorders. This study demonstrates the need to work towards optimizing and standardizing pain management techniques in aesthetic patients.

This cross-sectional study examines the prevalence of preoperative opioid prescribing and the specialties of clinicians who prescribe these medications.

Association of Limiting Opioid Prescriptions With Use of Opioids After Corneal Surgery

Importance

Opioids, which carry a high risk for addiction and overdose, are commonly prescribed after corneal surgery. Data are lacking describing opioid prescribing practices and opioid needs by patients after ophthalmic surgery.

Objectives

To quantify opioid use and to assess the association of decreasing the number of opioid tablets prescribed after corneal surgery with postsurgical use.

Design, Setting, and Participants

This prospective cohort study investigated opioid use after corneal surgery using direct interviews of 2 adult patient cohorts separated by an updated opioid prescribing guideline. The first cohort survey assessed the quantity of opioid tablets used after surgery. The cornea division of a tertiary care academic medical center reviewed the use needs and decreased the number of tablets prescribed after routine cases. Simultaneously, a statewide opioid monitoring program began that provided patients with opioid information. A second unique cohort received a more detailed survey to assess use, opioid disposal, and pain control. Data for the first cohort were collected from December 1, 2017, through January 19, 2018; for the second cohort, from June 1 to September 15, 2018. Data were analyzed from October 24, 2018, through September 24, 2019.

Exposure

Corneal surgery.

Main Outcomes and Measures

Differences in use of opioid tablets used by both patient cohorts, assessed using the 2-sample t test.

Results

Of 112 eligible, contacted patients, 82 consented to participate (42 men [51%]; mean [SD] age, 42.5 [17.8] years) and were included in the analysis; 38 of 42 participated in the first cohort and 44 of 70 participated in the second cohort. Of those receiving opioid prescriptions, the first cohort was prescribed significantly more tablets than the second cohort (mean [SD], 18.8 [4.2] vs 6.6 [3.1]; difference, 12.2 [95% CI, 10.4-14.0]; P < .001). The first cohort used significantly more tablets than the second cohort (mean [SD], 8.3 [7.0] vs 4.0 [3.2]; difference, 4.3 [95% CI, 1.4-7.2]; P = .005) and had significantly more leftover tablets (mean [SD], 10.3 [6.9] vs 2.9 [2.7]; difference, 7.5 [95% CI, 4.7-10.2]; P < .001). In the detailed survey for the second cohort, 19 of 27 patients reported pain control as adequate (70% [95% CI, 50%-86%]); 6 of 27, as more than needed (22% [95% CI, 9%-42%]). Twenty of 28 participants (71% [95% CI, 55%-88%]) had leftover tablets; 17 of these (85% [95% CI, 62%-97%]) did not dispose of leftovers, and 3 (15% [95% CI, 3%-38%]) threw away or flushed leftovers.

Conclusions and Relevance

After an assessment of opioid needs, physicians prescribed fewer opioid pills. However, patients who underwent cornea surgery and received fewer tablets continued to have adequate pain control and used even fewer tablets compared with the initial cohort. Patients with unused opioid tablets did not dispose of them properly.

The Impact of Complications and Pain on Patient Satisfaction

OBJECTIVE

To measure the association between patient-reported satisfaction and regret and clinical outcomes.

SUMMARY OF BACKGROUND DATA

Patient-reported outcomes are becoming an increasingly important marker of the quality of patient care. It is unclear however, how well patient-reported outcomes adequately reflect care quality and clinical outcomes in surgical patients.

METHODS

Retrospective, population-based analysis of adults ages 18 and older undergoing surgery across 38 hospitals in Michigan between January 1, 2017 and May 31, 2018.

RESULTS

In this study, 9953 patients (mean age 56 years; 5634 women (57%)) underwent 1 of 16 procedures. 9550 (96%) patients experienced no complication, whereas 240 (2%) and 163 (2%) patients experienced Grade 1 and Grade 2-3 complications, respectively. Postoperative pain scores were: none (908 (9%) patients), mild (3863 (40%) patients), moderate (3893 (40%) patients), and severe (1075 (11%) patients). Overall, 7881 (79%) patients were highly satisfied and 8911 (91%) had absolutely no regret after surgery. Patients were less likely to be highly satisfied if they experienced a Grade 1 complication [odds ratio (OR) 0.50, 95% confidence interval (CI) 0.37-0.66], Grade 2-3 complication (OR 0.44, 95% CI 0.31-0.62), minimal pain (OR 0.80, 95% CI 0.64-0.99, moderate pain (OR 0.39, 95% CI 0.32-0.49), or severe pain (OR 0.23, 95% CI 0.18-0.29). Patients were less likely to have no regret if they experienced a Grade 1 complication (OR 0.48, 95% CI 0.33-0.70), Grade 2-3 complication (OR 0.39, 95% CI 0.25-0.60), moderate pain (OR 0.55, 95% CI 0.40-0.76), or severe pain (OR 0.22, 95% CI 0.16-0.31). The predicted probability of being highly satisfied was 79% for patients who had no complications and 88% for patients who had no pain.

CONCLUSIONS

Patients who experienced postoperative complications and pain were less likely to be highly satisfied or have no regret. Notably, postoperative pain had a more significant effect on satisfaction and regret after surgery, suggesting focused postsurgical pain management is an opportunity to substantially improve patient experiences. More research and patient education are needed for managing expectations of postoperative pain, and use of adjuncts and regional anesthesia.

Relationship between initial opioid prescription size and likelihood of refill after spine surgery

BACKGROUND CONTEXT

Best practices in opioid prescribing after elective surgery have been developed for most surgical subspecialties, including spine. However, some percentage of patients will become chronic users.

PURPOSE

This study aimed to determine the relationship between the size of initial opioid prescription after surgery for degenerative spinal disease and the likelihood of refills.

STUDY DESIGN/SETTING

Retrospective case-control study.

PATIENT SAMPLE

Opioid-naïve patients aged 18 to 64 undergoing elective spinal procedures (anterior cervical discectomy and fusion, posterior cervical fusion, lumbar decompression, and lumbar fusion) from 2010 to 2015 filling an initial perioperative prescription using insurance claims from Truven Health MarketScan (n=25,329).

OUTCOME MEASURES

Functional measure: health-care utilization. Primary outcome was occurrence of an opioid refill within 30 postoperative days.

METHODS

We used logistic regression to examine the probability of an additional refill by initial opioid prescription strength, adjusting for patient factors.

RESULTS

About 26.3% of opioid-naïve patients obtained refills of their opioid prescriptions within 30 days of surgery. The likelihood of obtaining a refill was unchanged with the size of the initial perioperative prescription across procedure categories. Patient factors associated with increased likelihood of refills included age 30 to 39 years (odds ratio [OR] 1.137, p=.007, 95% confidence interval [CI] 1.072-1.249), female gender (OR 1.137, p<.001, 95% CI 1.072-1.207), anxiety disorder (OR 1.141, p=.017, 95% CI 1.024-1.272), mood disorder (OR 1.109 p=.049, 95% CI 1.000-1.229), and history of alcohol/substance abuse (OR 1.445 p=.006, 95% CI 1.110-1.880).

CONCLUSIONS

For opioid-naïve patients, surgeons can prescribe lower amounts of opioids after elective surgery for degenerative spinal disease without concern of increased need for refills.

Bariatric surgery and the risk of alcohol-related cirrhosis and alcohol misuse

BACKGROUND & AIMS

Bariatric surgery is common, but alcohol misuse has been reported following these procedures. We aimed to determine if bariatric surgery is associated with increased risk of alcohol-related cirrhosis (AC) and alcohol misuse.

METHODS

Retrospective observational analysis of obese adults with employer-sponsored insurance administrative claims from 2008 to 2016. Subjects with diagnosis codes for bariatric surgery were included. Primary outcome was risk of AC. Secondary outcome was risk of alcohol misuse. Bariatric surgery was divided into before 2008 and after 2008 to account for patients who had a procedure during the study period. Cox proportional hazard regression models using age as the time variable were used with interaction analyses for bariatric surgery and gender.

RESULTS

A total of 194 130 had surgery from 2008 to 2016 while 209 090 patients had bariatric surgery prior to 2008. Age was 44.1 years, 61% women and enrolment was 3.7 years. A total of 4774 (0.07%) had AC. Overall risk of AC was lower for those who received sleeve gastrectomy and laparoscopic banding during the study period (HR 0.4, P <.001; HR 0.43, P =.02) and alcohol misuse increased for Roux-en-Y and sleeve gastrectomy recipients (HR 1.86 and 1.35, P <.001, respectively). In those who had surgery before 2008, women had increased risk of AC and alcohol misuse compared to women without bariatric surgery (HR 2.1 [95% CI: 1.79-2.41] for AC; HR 1.98 [95% CI 1.93-2.04]).

CONCLUSIONS

Bariatric surgery is associated with a short-term decreased risk of AC but potential long-term increased risk of AC in women. Post-operative alcohol surveillance is necessary to reduce this risk.

Patient and provider perspectives of a new prenatal care model introduced in response to the coronavirus disease 2019 pandemic

BACKGROUND

Randomized controlled trials document the safety and efficacy of reduced frequency prenatal visit schedules and virtual visits, but real-world data are lacking. Our institution created a prenatal care delivery model incorporating these alternative approaches to continue safely providing prenatal care during the coronavirus disease 2019 pandemic.

OBJECTIVE

To evaluate institutional-level adoption and patient and provider experiences with the coronavirus disease 2019 prenatal care model.

STUDY DESIGN

We conducted a single-site evaluation of a coronavirus disease 2019 prenatal care model incorporating a reduced frequency visit schedule and virtual visits deployed at a suburban academic institution on March 20, 2020. We used electronic health record data to evaluate institution-level model adoption, defined as changes in overall visit frequency and proportion of virtual visits in the 3 months before and after implementation. To evaluate the patient and provider experience with the coronavirus disease 2019 model, we conducted an online survey of all pregnant patients (>20 weeks' gestation) and providers in May 2020. Of note, 3 domains of care experience were evaluated: (1) access, (2) quality and safety, and (3) satisfaction. Quantitative data were analyzed with basic descriptive statistics. Free-text responses coded by the 3 survey domains elucidated drivers of positive and negative care experiences.

RESULTS

After the coronavirus disease 2019 model adoption, average weekly prenatal visit volume fell by 16.1%, from 898 to 761 weekly visits; the average weekly proportion of prenatal visits conducted virtually increased from 10.8% (97 of 898) to 43.3% (330 of 761); and the average visit no-show rate remained stable (preimplementation, 4.3%; postimplementation, 4.2%). Of those eligible, 74.8% of providers (77 of 103) and 15.0% of patients (253 of 1690) participated in the surveys. Patient respondents were largely white (180 of 253; 71.1%) and privately insured (199 of 253; 78.7%), reflecting the study site population. The rates of chronic conditions and pregnancy complications also differed from national prevalence. Provider respondents were predominantly white (44 of 66; 66.7%) and female (50 of 66; 75.8%). Most patients and almost all providers reported that virtual visits improved access to care (patients, 174 of 253 [68.8%]; providers, 74 of 77 [96.1%]). More than half of respondents (patients, 124 of 253 [53.3%]; providers, 41 of 77 [62.1%]) believed that virtual visits were safe. Nearly all believed that home blood pressure cuffs were important for virtual visits (patients, 213 of 231 [92.2%]; providers, 63 of 66 [95.5%]). Most reported satisfaction with the coronavirus disease 2019 model (patients, 196 of 253 [77.5%]; providers, 64 of 77 [83.1%]). In free-text responses, drivers of positive care experiences were similar for patients and providers and included perceived improved access to care through decreased barriers (eg, transportation, childcare), perceived high quality of virtual visits for low-risk patients and increased safety during the pandemic, and improved satisfaction through better patient counseling. Perceived drivers of negative care experience were also similar for patients and providers, but less common. These included concerns that unequal access to virtual visits could deepen existing maternity care inequities, concerns that the lack of home devices (eg, blood pressure cuffs) would affect care quality and safety, and dissatisfaction with poor patient-provider continuity and inadequate expectation setting for the virtual visit experience.

CONCLUSION

Reduced visit schedules and virtual visits were rapidly integrated into real-world care, with positive experiences for many patients and providers. Future research is needed to understand the health outcomes and care experience associated with alternative approaches to prenatal care delivery across more diverse patient populations outside of the coronavirus disease 2019 pandemic to inform broader health policy decisions.

The Relationship Between Surgeon Gender and Stress During the Covid-19 Pandemic

OBJECTIVE

To investigate the relationship between surgeon gender and stress during the Covid-19 pandemic.

BACKGROUND

Although female surgeons face difficulties integrating work and home in the best of times, the Covid-19 pandemic has presented new challenges. The implications for the female surgical workforce are unknown.

METHODS

This cross-sectional, multi-center telephone survey study of surgeons was conducted across 5 academic institutions (May 15-June 5, 2020). The primary outcome was maximum stress level, measured using the validated Stress Numerical Rating Scale-11. Mixed-effects generalized linear models were used to estimate the relationship between surgeon stress level and gender.

RESULTS

Of 529 surgeons contacted, 337 surgeons responded and 335 surveys were complete (response rate 63.7%). The majority of female respondents were housestaff (58.1%), and the majority of male respondents were faculty (56.8%) (P = 0.008). A greater proportion of male surgeons (50.3%) than female surgeons (36.8%) had children ≤18 years (P = 0.015). The mean maximum stress level for female surgeons was 7.51 (SD 1.49) and for male surgeons was 6.71 (SD 2.15) (P < 0.001). After adjusting for the presence of children and training status, female gender was associated with a significantly higher maximum stress level (P < 0.001).

CONCLUSIONS

Our findings that women experienced more stress than men during the Covid-19 pandemic, regardless of parental status, suggest that there is more to the gendered differences in the stress experience of the pandemic than the added demands of childcare. Deliberate interventions are needed to promote and support the female surgical workforce during the pandemic.

Predicting postoperative opioid use with machine learning and insurance claims in opioid-naïve patients

BACKGROUND

The clinical impact of postoperative opioid use requires accurate prediction strategies to identify at-risk patients. We utilize preoperative claims data to predict postoperative opioid refill and new persistent use in opioid-naïve patients.

METHODS

A retrospective study was conducted on 112,898 opioid-naïve adult postoperative patients from Optum's de-identified Clinformatics® Data Mart database. Potential predictors included sociodemographic data, comorbidities, and prescriptions within one year prior to surgery.

RESULTS

Compared to linear models, non-linear models led to modest improvements in predicting refills - area under the receiver operating characteristics curve (AUROC) 0.68 vs. 0.67 (p < 0.05) - and performed identically in predicting new persistent use - AUROC = 0.66. Undergoing major surgery, opioid prescriptions within 30 days prior to surgery, and abdominal pain were useful in predicting refills; back/joint/head pain were the most important features in predicting new persistent use.

CONCLUSIONS

Preoperative patient attributes from insurance claims could potentially be useful in guiding prescription practices for opioid-naïve patients.

Nurses' Experiences with Implementation of a Postcesarean Birth Opioid-Sparing Protocol

PURPOSE

Opioid-sparing protocols have significantly reduced opioid use postcesarean birth through maximizing nonpharmacologic and nonopioid pain management tools. This study explored nurses' experiences with an opioid-sparing protocol at a single institution, where inpatient opioid prescribing was reduced by over half.

METHOD

Focus groups were used to identify key facilitators and barriers to implementation of the opioid-sparing protocol. The Consolidated Framework for Implementation Research (CFIR) guided data collection and analysis. Focus groups were recorded, transcribed, thematically coded, and analyzed for barriers and facilitators using predetermined CFIR domains.

RESULTS

Three focus groups of nurses who care for women during postpartum were conducted in March and April 2019. Fourteen nurses participated. They were all women, with an average of 9.3 years (SD = 5.4) of maternity nursing experience. Facilitators of implementation were: 1) high satisfaction with the intervention's efficacy; 2) awareness of opioid harms promoting readiness for opioid-sparing efforts; 3) adequate staffing and the culture of evidence-based practice; and 4) bedside skills in pain management to identify patients' needs. The most significant barrier was a lack of nurse engagement with protocol development and implementation.

CLINICAL IMPLICATIONS

An increased partnership among the interprofessional team members through all stages of implementation is necessary for the success and sustainability of best patient care practices.

Exploring the Experience of the Surgical Workforce During the Covid-19 Pandemic

OBJECTIVE

To explore the impact of the Covid-19 pandemic on the stress levels and experience of academic surgeons by training status (eg, housestaff or faculty).

BACKGROUND

Covid-19 has uniquely challenged and changed the United States healthcare system. A better understanding of the surgeon experience is necessary to inform proactive workforce management and support.

METHODS

A multi-institutional, cross-sectional telephone survey of surgeons was conducted across 5 academic medical centers from May 15 to June 5, 2020. The exposure of interest was training status. The primary outcome was maximum stress level, measured using the validated Stress Numerical Rating Scale-11 (range 0-10).

RESULTS

A total of 335 surveys were completed (49.3% housestaff, 50.7% faculty; response rate 63.7%). The mean maximum stress level of faculty was 7.21 (SD 1.81) and of housestaff was 6.86 (SD 2.06) (P = 0.102). Mean stress levels at the time of the survey trended lower amongst housestaff (4.17, SD 1.89) than faculty (4.56, SD 2.15) (P = 0.076). More housestaff (63.6%) than faculty (40.0%) reported exposure to individuals with Covid-19 (P < 0.001). Subjects reported inadequate personal protective equipment in approximately a third of professional exposures, with no difference by training status (P = 0.557).

CONCLUSIONS

During the early months of the Covid-19 pandemic, the personal and professional experiences of housestaff and faculty differed, in part due to a difference in exposure as well as non-work-related stressors. Workforce safety, including adequate personal protective equipment, expanded benefits (eg, emergency childcare), and deliberate staffing models may help to alleviate the stress associated with disease resurgence or future disasters.

Assessment of a quality improvement intervention to decrease opioid prescribing in a regional health system

BACKGROUND

Opioids are prescribed in excess after surgery. We leveraged our continuous quality improvement infrastructure to implement opioid prescribing guidelines and subsequently evaluate changes in postoperative opioid prescribing, consumption and patient satisfaction/pain in a statewide regional health system.

METHODS

We collected data regarding postoperative prescription size, opioid consumption and patient-reported outcomes from February 2017 to May 2019, from a 70-hospital surgical collaborative. Three iterations of prescribing guidelines were released. An interrupted time series analysis before and after each guideline release was performed. Linear regression was used to identify trends in consumption and patient-reported outcomes over time.

RESULTS

We included 36 022 patients from 69 hospitals who underwent one of nine procedures in the guidelines, of which 15 174 (37.3%) had complete patient-reported outcomes data following surgery. Before the intervention, prescription size was decreasing over time (slope: -0.7 tablets of 5 mg oxycodone/month, 95% CI -1.0 to -0.5 tablets, p<0.001). After the first guideline release, prescription size declined by -1.4 tablets/month (95% CI -1.8 to -1.0 tablets, p<0.001). The difference between these slopes was significant (p=0.006). The second guideline release resulted in a relative increase in slope (-0.3 tablets/month, 95% CI -0.1 to -0.6, p<0.001). The third guideline release resulted in no change (p=0.563 for the intervention). Overall, mean (SD) prescription size decreased from 25 (17) tablets of 5 mg oxycodone to 12 (8) tablets. Opioid consumption also decreased from 11 (16) to 5 (7) tablets (p<0.001), while satisfaction and postoperative pain remained unchanged.

CONCLUSIONS

The use of procedure-specific prescribing guidelines reduced statewide postoperative opioid prescribing by 50% while providing satisfactory pain care. These results demonstrate meaningful impact on opioid prescribing using evidence-based best practices and serve as an example of successful utilisation of a regional health collaborative for quality improvement.

High-Risk Prescribing Increases Rates of New Persistent Opioid Use in Total Hip Arthroplasty Patients

BACKGROUND

The association between surgeon prescribing practices and new persistent postoperative opioid use is not well understood. We examined the association between surgeon prescribing and new persistent use among total hip arthroplasty (THA) patients.

METHODS

A retrospective analysis of Medicare claims in Michigan was performed. The study cohort consisted of orthopedic surgeons performing THAs from 2013 to 2016 and their opioid-naïve patients, aged >65 years. High-risk prescribing included high daily doses, overlapping benzodiazepine prescriptions, concurrent opioid prescriptions, prescriptions from multiple providers, or long-acting opioid prescriptions. The occurrence of a preoperative prescription, initial prescription size, and 30-day prescription dosage were examined as individual exposures. Surgeons were categorized into quartiles by prescribing practices, and multilevel hierarchical logistic regression was used to examine associations with postoperative new persistent opioid use.

RESULTS

Surgeons exhibited high-risk prescribing for 66% of encounters. Patients of surgeons with the highest rates of high-risk prescribing were more likely to develop persistent use compared with patients of surgeons with the lowest rates (adjusted rates: 9.7% vs 4.6%, P = .011). Patients of surgeons with initial prescription sizes in the "high" (third) quartile (adjusted odds ratio, 2.91; 95% confidence interval, 1.53-5.51), and of surgeons in the "highest" (fourth) quartile of 30-day prescription dosage (adjusted odds ratio, 1.93; 95% confidence interval, 1.03-3.61), were more likely to develop persistent opioid use compared with patients of surgeons with low initial and 30-day prescription sizes, respectively.

CONCLUSION

The development of persistent opioid use after surgery is multifactorial, and surgeon prescribing patterns play an important role. Reducing prescribing and encouraging opioid alternatives could minimize postoperative persistent opioid use.

Care Coordination for Patients on Chronic Opioid Therapy Following Surgery: A Cohort Study

OBJECTIVE

To describe if patients with chronic opioid use with a consistent usual prescriber (UP) prior to surgery and if early return to that UP (<30 d) would be associated with fewer high risk prescribing events in the postoperative period.

SUMMARY BACKGROUND DATA

Over 10 million people each year are prescribed opioids for chronic pain. There is little evidence regarding coordination of opioid management and best practices for patients on long-term opioid therapy patients following surgery.

METHODS

The study design is a retrospective cohort study. We identified 5749 commercially insured patients aged 18 to 64 with chronic opioid use who underwent elective surgery between January 2008 and March 2015. The predictors were presence of a UP and early return (<30 d from surgery) to a UP. The primary outcome was new high-risk opioid prescribing in the 90-day postoperative period (multiple prescribers, overlapping opioid and/or benzodiazepine prescriptions, new long acting opioid prescriptions, or new dose escalations to > 100 mg OME).

RESULTS

In this cohort, 73.8% of patients were exposed to high risk prescribing postoperatively. Overall, 10% of patients did not have a UP preoperatively, and were more likely to have prescriptions from multiple prescribers (OR 2.23 95% CI 1.75-2.83) and new long acting opioid prescriptions (OR 1.69, 95% CI 1.05-2.71). Among patients with a UP, earlier return was associated with decreased odds of receiving prescriptions from multiple prescribers (OR 0.80, 95% CI 0.68-0.95).

CONCLUSION

Patients without a UP prior to surgery are more likely to be exposed to high-risk opioid prescribing following surgery. Among patients who have a UP, early return visits may enhance care coordination with fewer prescribers.

Variation in the Utilization of Postoperative Computed Tomography for Patients With Nonsyndromic Craniosynostosis: A National Claims Analysis

OBJECTIVE

Routine postoperative computed tomography (CT) imaging in nonsyndromic craniosynostosis remains controversial due to the hazards of radiation exposure. The extent to which postoperative head CTs are performed remains unknown. Therefore, we sought to measure the use of postoperative CTs in this population.

DESIGN

The authors reviewed insurance claims from OptumInsight, using Current Procedural Terminology codes to identify procedures and postoperative imaging. Multilevel logistic regression was used to describe the odds of undergoing postoperative CTs, adjusting for patient and provider covariates.

PARTICIPANTS

Craniosynostosis patients who underwent reconstruction between 2001 and 2017 were reviewed. Patients older than 5 years at surgery, postoperative lengths of stay >15 days, syndromic diagnoses, operative complications within 30 days of surgery, and cranial bone grafting merited exclusion.

MAIN OUTCOME MEASURE

Odds of postoperative head CTs after cranial vault reconstruction.

RESULTS

In this cohort (n = 1150), 326 (28.4%) patients underwent postoperative head CTs. The number of CTs ranged from 0 to 14. Older age at surgery (odds ratio [OR]: 1.32, P = .002), increasing years of follow-up (OR: 1.12, P < .001), and increasing comorbidities (OR: 1.21, P = .017) were associated with postoperative CTs. After adjusting for patient factors, provider factors accounted for 31.3% of variation in imaging.

CONCLUSIONS

Over a quarter of patients underwent head CTs following reconstruction, and provider factors accounted for a large percentage of the variation. Given the risks of radiation, neurosurgeons and craniofacial surgeons face a critical need to establish postoperative imaging protocols to reduce unnecessary imaging in these vulnerable patients.

Prevalence of Preoperative Opioid Use and Characteristics Associated With Opioid Use Among Patients Presenting for Surgery

Importance

Patterns of preoperative opioid use are not well characterized across different surgical services, and studies in this patient population have lacked important self-reported data of pain and affect.

Objectives

To assess the prevalence of preoperative opioid use and the characteristics of these patients in a broadly representative surgical cohort.

Design, Setting, and Participants

Cross-sectional, observational study of patients undergoing surgery at a tertiary care academic medical center. Data were collected as a part of large prospective institutional research registries from March 1, 2010, through April 30, 2016.

Exposures

Preoperative patient and procedural characteristics, including prospectively assessed self-reported pain and functional measures.

Main Outcomes and Measures

Patient-reported opioid use before surgery.

Results

Of the total 34 186 patients recruited (54.2% women; mean [SD] age, 53.1 [16.1] years), preoperative opioid use was reported in 7894 (23.1%). The most common opioids used were hydrocodone bitartrate (4685 [59.4%]), tramadol hydrochloride (1677 [21.2%]), and oxycodone hydrochloride (1442 [18.3%]). Age of 31 to 40 years (adjusted odds ratio [aOR], 1.26; 95% CI, 1.10-1.45), tobacco use (former use aOR, 1.32 [95% CI, 1.22-1.42]; current use aOR, 1.62 [95% CI, 1.48-1.78]), illicit drug use (aOR, 1.74; 95% CI, 1.16-2.60), higher pain severity (aOR, 1.33; 95% CI, 1.31-1.35), depression (aOR, 1.22; 95% CI, 1.12-1.33), higher Fibromyalgia Survey scores (aOR, 1.06, 95% CI, 1.05-1.07), lower life satisfaction (aOR, 0.95, 95% CI, 0.93-0.96), and more medical comorbidities (American Society of Anesthesiology score aOR, 1.47 [95% CI, 1.37-1.58]; Charlson Comorbidity Index aOR, 1.29 [95% CI, 1.18-1.41]) were all independently associated with preoperative opioid use. Preoperative opioid use was most commonly reported by patients undergoing orthopedic (226 [65.1%]) and neurosurgical spinal (596 [55.1%]) procedures and least common among patients undergoing thoracic procedures (244 [15.7%]). After adjusting for patient characteristics, the patients undergoing lower extremity procedures were most likely to report preoperative opioid use (aOR, 3.61; 95% CI, 2.81-4.64), as well as those undergoing pelvic (excluding hip) (aOR, 3.09; 95% CI, 1.88-5.08), upper extremity (aOR, 3.07; 95% CI, 2.12-4.45), and spinal or spinal cord (aOR, 2.68; 95% CI, 2.15-3.32) procedures, with the group undergoing intrathoracic surgery as the reference group.

Conclusions and Relevance

In this large study of preoperative opioid use that includes patient-reported outcome measures, more than 1 in 4 patients presenting for surgery reported opioid use. These data provide important insights into this complicated patient population that would appear to help guide future preoperative optimization and perioperative opioid-weaning interventions.

Association of Hydrocodone Schedule Change With Opioid Prescriptions Following Surgery

Importance

In 2014, the US Drug Enforcement Administration moved hydrocodone-containing analgesics from schedule III to the more restrictive schedule II to limit prescribing and decrease nonmedical opioid use. The association of this policy change with postoperative prescribing is not well understood.

Objective

To examine the hypothesis that the amount of opioids prescribed following surgery is associated with the rescheduling of hydrocodone.

Design, Setting, and Participants

An interrupted time series analysis of outpatient opioid prescriptions was conducted to examine the trends in the amount of postoperative opioids filled before and after the schedule change. Opioid prescriptions filled between January 2012 and October 2015 were analyzed using insurance claims data from the Michigan Value Collaborative, which includes data from 75 hospitals across Michigan. A total of 21 955 adult inpatients 18 to 64 years of age who underwent 1 of 19 common elective surgical procedures and filled an opioid prescription within 14 days of discharge to home were eligible for inclusion.

Main Outcomes and Measures

The primary outcome was the trends in the mean amount of opioids filled in oral morphine equivalents (OMEs) for the initial postoperative prescriptions before and after the schedule change date of October 6, 2014, compared using interrupted time series and multivariable regression analyses. Secondary outcomes included the total amount of opioids filled and the refill rate for the 30-day postoperative period. Subgroup analyses were performed by hydrocodone prescriptions, nonhydrocodone prescriptions, surgical procedure, and prior opioid use.

Results

Data from 21 955 patients undergoing surgical procedures across 75 hospitals and 5120 prescribers were analyzed. Cohorts before and after the schedule change were equivalent with respect to sex (10 197 of 15 791 [64.6%] vs 3966 of 6169 [64.3%] female; P = .69) and mean (SE) age (47.9 [11.2] vs 47.7 [11.3] years; P = .19). After the schedule change, the mean OMEs filled in the initial opioid prescription increased by approximately 35 OMEs (β = 35.1 [13.2]; P < .01), equivalent to 7 tablets of hydrocodone (5 mg). There were no significant differences in the total OMEs filled during the 30-day postoperative period before and after the schedule change (β = 18.3 [30.5]; P = .55), but there was a significant decrease in the refill rate (β = -5.2% [1.3%]; P < .001).

Conclusions and Relevance

Changing hydrocodone from schedule III to schedule II was associated with an increase in the amount of opioids filled in the initial prescription following surgery. Opioid-related policies require close follow-up to identify and address early unintended effects given the multitude of competing factors that influence health care professional prescribing behaviors.

Effects of Shared Decision Making on Opioid Prescribing After Hysterectomy

OBJECTIVE

To evaluate the effects of shared decision making using a simple decision aid for opioid prescribing after hysterectomy.

METHODS

We conducted a prospective quality initiative study including all patients undergoing hysterectomy for benign, nonobstetric indications between March 1, 2018, and July 31, 2018, at our academic institution. Using a visual decision aid, patients received uniform education regarding postoperative pain management. They were then educated on the department's guidelines regarding the maximum number of tablets recommended per prescription and the mean number of opioid tablets used by a similar cohort of patients in a previously published study at our institution. Patients were then asked to choose their desired number of tablets to receive on discharge. Structured telephone interviews were conducted 14 days after surgery. The primary outcome was total opioids prescribed before compared with after implementation of the decision aid. Secondary outcomes included opioid consumption, patient satisfaction, and refill requests after intervention implementation.

RESULTS

Of 170 eligible patients, 159 (93.5%) used the decision aid (one patient who used the decision aid was subsequently excluded from the analysis owing to significant perioperative complications), including 110 (69.6%) laparoscopic, 40 (25.3%) vaginal, and eight (5.3%) abdominal hysterectomies. Telephone surveys were completed for 89.2% (n=141) of participants. Student's t-test showed that patients who participated in the decision aid (post-decision aid cohort) were discharged with significantly fewer oral morphine equivalents than patients who underwent hysterectomy before implementation of the decision aid (pre-decision aid cohort) (92±35 vs 160±81, P<.01), with no significant change in the number of requested refills (9.5% [n=15] vs 5.7% [n=14], P=.15). In the post-decision aid cohort, 76.6% of patients (n=121) chose fewer tablets than the guideline-allotted maximum. Approximately 76% of patients (n=102) reported having leftover tablets.

CONCLUSION

This quality improvement initiative illustrates that a simple decision aid can result in a significant decrease in opioid prescribing without compromising patient satisfaction or postoperative pain management.

Optimizing Postoperative Opioid Prescribing Through Quality-Based Reimbursement

This quality improvement study examines the use of a novel reimbursement incentive for surgeons to counsel patients on an opioid-sparing pathway for postoperative pain management.
