Peripheral Nerve Block Delays Mobility and Increases Length of Stay in Patients With Geriatric Hip Fracture.

INTRODUCTION: Peripheral nerve blocks (PNB) has been increasingly used in the care of patients with geriatric hip fracture to reduce perioperative opiate use and the need for general anesthesia. However, the associated motor palsy may impair patients' ability to mobilize effectively after surgery and subsequently may increase latency to key mobility milestones postoperatively, as well as increase inpatient length of stay (LOS). The aim of this study was to investigate time-to-mobility milestones and length of hospital stay between peripheral, epidural, and general anesthesia. METHODS: A retrospective review identified 1,351 patients aged 65 years or older who underwent surgery for hip fracture between 2012 and 2018 at a single academic health system. Patients were excluded if baseline nonambulatory, restricted weight-bearing postoperatively, or sustained concomitant injuries precluding mobilization, with a final cohort of 1,013 patients. Time-to-event analyses for discharge and mobility milestones were assessed using univariate Kaplan-Meier and multivariate Cox proportional hazard regression analyses. RESULTS: PNB was associated with delayed postoperative time to ambulation ( P < 0.001) and time to out-of-bed ( P = 0.029), along with increased LOS ( P < 0.001). Epidural anesthesia was associated with less delay to first out-of-bed ( P = 0.002), less delay to ambulation ( P = 0.001), and overall reduced length of stay ( P < 0.001). DISCUSSION: PNB was associated with slower mobilization and longer hospitalization while epidural anesthesia was associated with quicker mobilization and shorter hospital stays. Epidural anesthesia may be a preferable anesthesia choice in patients with geriatric hip fracture when possible. LEVEL OF EVIDENCE: Level III.

Beware the rebound effect: regional anesthesia increases opioid utilization after humerus fracture surgery.

Introduction: Regional anesthesia (RA) is used reduce pain in proximal humerus and humeral shaft fracture surgery. The study hypothesis was that RA would decrease opioid demand in patients undergoing fracture surgery. Materials and methods: Opioid demand was recorded in all patients ages 18 and older undergoing proximal humerus or humeral shaft fracture surgery at a single, Level I trauma center from 7/2013 - 7/2018 (n = 380 patients). Inpatient opioid consumption from 0-24, 24-48, and 48-72 h and outpatient opioid demand from 1-month pre-operative to 90-days post-operative were converted to oxycodone 5-mg equivalents (OE's). Unadjusted and adjusted models were constructed to evaluate the impact of RA and other factors on opioid utilization. Results: Adjusted models demonstrated increases in inpatient opioid consumption in patients with RA (6.8 estimated OE's without RA vs 8.8 estimated OE's with RA from 0-24 h post-op; 10 vs 13.7 from 24-48 h post-op; and 8.7 vs 11.6 from 48-72 h post-op; all p < 0.05). Estimated cumulative outpatient opioid demand was significantly higher in patients with RA at all timepoints. Discussion: In proximal humerus and humeral shaft fracture surgery, RA was associated with increased inpatient and outpatient opioid demand after adjusting for baseline patient and treatment characteristics.

Psychological resilience as a predictor of opioid consumption after orthopaedic trauma.

INTRODUCTION: Psychological distress after orthopaedic trauma negatively affects patient outcomes. Resilience may mediate distress and therefore be associated with post-operative outcomes, including opioid use. The purpose of this study is to evaluate the relationship between resilience and post-operative opioid demand with the hypothesis that low levels of resilience are associated with increased opioid consumption. MATERIALS AND METHODS: Patients age 18 - 65 at a single, tertiary care level 1 trauma center who underwent operative treatment of pelvic and/ or extremity fractures between 3/2017 - 6/2018 were contacted by phone to complete the OSPRO-YF, a ten-item screening tool that assesses psychological distress. Participants were screened for scores in the worst quartile (i.e., yellow flag) for resilience. Baseline patient and injury characteristics and opioid demand were compared between patients with and without positive yellow flags for resilience using Wilcoxon rank-sum for continuous variables and Fisher exact test for categorical variables. RESULTS: A total of 117 patients were surveyed. Patients with positive yellow flag screening scores for resilience had significantly higher opioid demand, number of opioid prescriptions filled, and were more likely to refill prescriptions long-term (3-months post-discharge to one-year post-discharge). Patients with a positive yellow flag for resilience had a significantly higher number of opioid prescriptions filled in the cumulative (one-month pre-op to one-year post-discharge) time period. DISCUSSION/ CONCLUSION: Lower long-term resilience scores were associated with higher postoperative opioid consumption, fill and refill rates. These results suggest low resilience may be a risk factor for increased long-term opioid consumption following surgical treatment for orthopaedic trauma.

Regional anesthesia does not decrease opioid demand in pelvis and acetabulum fracture surgery.

INTRODUCTION: Patients with pelvic and acetabular fractures often have considerable pain in the perioperative period. Regional anesthesia (RA) including peripheral nerve blocks and spinal analgesia may reduce pain. However, the real-world impact of these modalities on inpatient opioid consumption and outpatient opioid demand is largely unknown. The purpose of this study was to evaluate the impact of perioperative RA on inpatient opioid consumption and outpatient opioid demand. METHODS: This is a retrospective, observational review of inpatient opioid consumption and outpatient opioid demand in all patients ages 18 and older undergoing operative fixation of pelvic and acetabular fractures at a single Level, I trauma center from 7/1/2013-7/1/2018 (n = 205). Unadjusted and adjusted analyses were constructed to evaluate the impact of RA on inpatient opioid consumption and outpatient opioid demand while controlling for age, sex, race, body mass index (BMI), smoking, chronic opioid use, ASA score, injury mechanism, additional injuries, open injury, and additional inpatient surgery. RESULTS: Adjusted models demonstrated increases in inpatient opioid consumption in patients with RA (12.6 estimated OE's without RA vs 16.1 OE's with RA from 48 to 72 h post-op, p < 0.05) but no significant differences at other timepoints (17.5 estimated OE's without RA vs 16.8 OE's with RA from 0 to 24 h post-op, 15.3 vs 17.1 from 24 to 48 h post-op, p > 0.05). Estimated cumulative outpatient opioid demand was significantly higher in patients with RA at discharge to 90 days post-op (and 156.8 vs 207.9 OE's to 90 days, p < 0.05) but did not differ significantly before that time (121.5 OE's without RA vs 123.9 with RA from discharge to two weeks, 145.2 vs 177.2 OE's to 6 weeks, p > 0.05). DISCUSSION: In pelvis and acetabulum fracture surgery, RA was associated with increased inpatient and outpatient opioid demand after adjusting for baseline patient and treatment characteristics. Regional anesthesia may not be beneficial for these patients.

Regional anesthesia reduces inpatient and outpatient perioperative opioid demand in periarticular elbow surgery.

HYPOTHESIS: Regional anesthesia (RA) can be used to manage perioperative pain in the treatment of periarticular elbow fracture fixation. However, the opioid-sparing benefit is not well-characterized. The hypothesis of this study was that RA had reduced inpatient opioid consumption and outpatient opioid demand in patients who had undergone periarticular elbow fracture surgery. METHODS: This study retrospectively reviews inpatient opioid consumption and outpatient opioid demand in all patients aged ≥18 years at a single Level I trauma center undergoing fixation of periarticular elbow (distal humerus and proximal forearm) fracture surgery (n=418 patients). In addition to RA vs. no RA, additional patient and operative characteristics were recorded. Unadjusted and adjusted models were constructed to evaluate the impact of RA and other factors on inpatient opioid consumption and outpatient opioid demand. RESULTS: Adjusted models demonstrated decreases in inpatient opioid consumption postoperation in patients with RA (13.7 estimated oxycodone 5-mg equivalents or OEs without RA vs. 10.4 OEs with RA from 0 to 24 hours postoperation, P = .003; 12.3 vs. 9.2 OEs from 24 to 48 hours postoperation, P = .045). Estimated cumulative outpatient opioid demand differed significantly in patients with RA (166.1 vs. 132.1 OEs to 6 weeks, P = .002; and 181 vs. 138.6 OEs to 90 days, P < .001). DISCUSSION: In proximal forearm and distal humerus fracture surgery, RA was associated with decreased inpatient and outpatient opioid demand after adjusting for baseline patient and treatment characteristics. These results encourage utilization of perioperative RA to reduce opioid use.

Regional anesthesia does not decrease inpatient or outpatient opioid demand in distal femur fracture surgery.

INTRODUCTION: Regional anesthesia (RA) is sometimes used to decrease pain and opioid consumption in distal femur fractures. However, the real-world impact of RA on inpatient opioid consumption and outpatient opioid demand is not well known. The hypothesis of this study is that RA would be associated with decreased inpatient opioid consumption and outpatient opioid demand. METHODS: This study evaluated inpatient post-operative opioid consumption (0-24 h, 24-48 h, 48-72 h) and outpatient opioid demand (discharge to 2 weeks, 6 weeks, and 90 days) in all patients ages 18 and older undergoing operative treatment of distal femur fractures at a single institution from 7/2013 to 7/2018 (n = 230). Unadjusted and adjusted multivariable models were used to evaluate the impact of RA and other baseline patient and operative characteristics on inpatient opioid consumption and outpatient opioid demand. RESULTS: Adjusted models demonstrated a small, significant increase in inpatient opioid consumption in patients with RA compared to no RA (4.7 estimated OE's without RA vs 6.2 OE's with RA from 24- to 48-h post-op, p < 0.05) but otherwise no significant differences at other timepoints (6.7 estimated OE's without RA vs 6.9 OE's with RA from 0- to 24-h post-op and 4.5 vs 4.4 from 48- to 72-h post-op, p > 0.05). Estimated cumulative outpatient opioid demand was significantly higher in patients with RA from discharge to 6 weeks and to 90 days (55.8 OE's without RA vs 63.9 with RA from discharge to 2 weeks, p > 0.05; 74.9 vs 95.1 OE's to 6 weeks, and 85 vs 113.1 OE's to 90 days, p < 0.05). DISCUSSION: In distal femur fracture surgery, RA was associated with increased inpatient and outpatient opioid demand after adjusting for baseline patient and treatment characteristics. These results call into question the routine use of RA in distal femur fractures. LEVEL OF EVIDENCE: Level III, retrospective, therapeutic cohort study.

Regional anesthesia does not decrease inpatient or outpatient opioid demand in femoral shaft fracture surgery.

INTRODUCTION: Regional anesthesia (RA) may be used in femoral shaft fracture surgery to decrease pain and opioid consumption. However, the impact of RA on inpatient and outpatient opioid demand in patients undergoing femoral shaft fracture surgery is largely unknown. The aim of this study was to evaluate the impact of RA on inpatient opioid consumption and outpatient opioid demand in patients undergoing femoral shaft fracture surgery. METHODS: Inpatient opioid consumption and outpatient opioid demand in all patients undergoing femoral shaft fracture surgery was recorded at a single, Level I trauma center from 7/2013 - 7/2018 (n=436). In addition to RA, baseline and treatment factors including age, sex, race, body mass index (BMI), smoking, chronic opioid use, American Society of Anesthesiologists (ASA) score, injury mechanism, additional injuries, open injury, and additional inpatient surgery were recorded. Unadjusted and adjusted multivariable models were used to evaluate the impact of RA on inpatient opioid consumption and outpatient opioid demand. RESULTS: Adjusted models demonstrated increases in inpatient opioid consumption in patients with RA (6.9 estimated OE's without RA vs 8.8 OE's with RA from 48-72 hours post-op, p<0.05) but no significant differences at other timepoints (10.3 estimated OE's without RA vs 9.2 OE's with RA from 0-24 hours post-op, 8.2 vs 8.8 from 24-48 hours post-op, p>0.05). Estimated cumulative outpatient opioid demand did not differ significantly in patients with RA (82.3 OE's without RA vs 94.8 with RA from discharge to two-weeks, 105.4 vs 116.3 OE's to 6-weeks, and 124.5 vs 137.9 OE's to 90-days, all p>0.05). Late opioid refills were significantly more common in patients with RA (1.57 odds at 2-weeks to 6-weeks, 1.69 odds at 6-weeks to 90-days, p<0.05) DISCUSSION: In femoral shaft fracture surgery, RA was not associated with decreased opioid demand after adjusting for baseline patient and treatment characteristics. These results provide a real-world estimate of the impact of RA on opioid demand in femoral shaft fracture surgery and encourage providers to seek alternative analgesic modalities. LEVEL OF EVIDENCE: Level III, retrospective, therapeutic cohort study.

Fracture location impacts opioid demand in upper extremity fracture surgery.

INTRODUCTION: Opioid sparing protocols should be formulated with appropriate demand. Specific fracture location has been hypothesized as an important predictor of post-operative pain. The purpose of this study is to evaluate the impact of fracture location on perioperative opioid demand after surgery with the hypothesis that this factor would be significantly associated with perioperative opioid demand in upper extremity fracture surgery. METHODS: A national database was used to identify1-month pre-operative to 1-year postdischarge opioid demand in oxycodone 5-mg equivalents in 336,493 patients undergoing fracture fixation of the clavicle through distal radius between 2010 and 2020. Three timeframes were evaluated: 1-month pre-op to 90-days post-discharge, 3 months post-discharge to 1-year post-discharge, and 1-month pre-op to 1-year postdischarge. Multivariable main effects linear and logistic regression models were constructed to evaluate the changes in opioids filled, opioid prescriptions, and odds of two or more opioid prescriptions in these timeframes based on fracture location with adjustment for age, sex, obesity, pre-operative opioid usage, and polytrauma. RESULTS: Compared to distal radius fracture fixation, fixation of elbow, distal humerus, humeral shaft, and proximal humerus fractures were associated with large, significant increases in 1-month pre-op to 1-year post-discharge opioid filling (33.5 - 63.4 additional oxycodone 5-mg equivalents, all p<0.05) and number of filled prescriptions (0.33 - 0.92 additional prescriptions, all p<0.05) compared to patients with other operatively treated upper extremity injuries. DISCUSSION: Fracture location was a significant predictor of perioperative opioid demand. Elbow, distal humerus, humeral shaft, and proximal humerus fracture fixation was associated with the largest increases in opioid demand after upper extremity fracture fixation. Patients with these injuries may be at highest risk of extensive opioid consumption. LEVEL OF EVIDENCE: Level III, retrospective, observational cohort study.

Mental health and substance use affect perioperative opioid demand in upper extremity trauma surgery.

BACKGROUND: Patients undergoing upper extremity fracture surgery often have postoperative pain that can be mitigated with opioid pain medications. Opioid misuse and abuse are growing concerns regarding the liberal use of opioids in the perioperative setting. The impact of mental health disorders and substance abuse on perioperative opioid demand is largely unknown. The purpose of this study is to describe perioperative opioid filling and risk factors for increased filling after upper extremity fractures. The study hypothesis is that poor mental health and substance abuse will be associated with increased opioid demand. METHODS: This is a retrospective, cohort study of 26,283 patients undergoing operative fixation of upper extremity fractures involving the proximal humerus through distal radius using a commercially available insurance database. Opioid prescription filling in oxycodone 5-mg equivalents and refills were tabulated from 1 month preoperation to 1 year postoperation. Multivariable linear and logistic regression models were constructed in R (Statistical Analysis Software) to evaluate associations between mental health and substance use disorders and opioid-related outcomes with adjustment for baseline patient and treatment factors such as age, sex, comorbidities, and fracture location. RESULTS: Of the 26,283 patients in the cohort, 79.9%, 32.6%, and 83.1% filled at least 1 opioid prescription in the 1-month preoperative to 90-day postoperative, 3-month postoperative to 1-year postoperative, and 1-month preoperative to 1-year postoperative time frames, respectively. Mean opioid volume prescribed during those time frames was 103.7, 53.5, and 156.9 oxycodone 5-mg equivalents, respectively. Drug abuse, psychoses, and preoperative opioid filling were significant mental health-related drivers of increased postoperative opioid demand. DISCUSSION: This study reports the rate and volume of opioid prescription filling in patients undergoing upper extremity fracture surgery. Mental health and substance use disorders were significant drivers of perioperative opioid demand. These study findings can guide surgeons to anticipate expected perioperative opioid demand and identify patients who may benefit from collaboration with pain management specialists during the perioperative period.

Impact of Substance Use and Abuse on Opioid Demand in Lower Extremity Fracture Surgery.

OBJECTIVES: To describe the perioperative opioid demand in a large population of patients undergoing lower extremity fracture fixation and to evaluate mental disorders such as substance abuse as risk factors for increased use. DESIGN: Retrospective, observational. SETTING: National insurance claims database. PATIENTS/PARTICIPANTS: Twenty-three four hundred forty-one patients grouped by mental disorders such as depression, psychoses, alcohol abuse, tobacco abuse, drug abuse, and preoperative opioid filling undergoing operative treatment of lower extremity fractures (femoral shaft through ankle) between 2007 and 2017. INTERVENTION: Operative treatment of lower extremity fractures. MAIN OUTCOME MEASURES: The primary outcome was filled opioid prescription volume converted to oxycodone 5-mg pill equivalents. Secondary outcomes included the number of filled prescriptions and the risk of obtaining 2 or more opioid prescriptions. RESULTS: Of 23,441 patients, 16,618 (70.9%), 8862 (37.8%), and 18,084 (77.1%) filled opioid prescriptions within 1-month preop to 90-day postop, 3-month postop to 1-year postop, and 1-month preop to 1-year postop, respectively. On average, patients filled 104, 69, and 173 oxycodone 5-mg pills at those time intervals. Alcohol, tobacco, drug abuse, and preoperative opioid filling were associated with increased perioperative opioid demand. Psychoses had a small effect on opioid demand, and depression had no significant impact. CONCLUSIONS: This study reports the rate and volume of opioid prescription filling in patients undergoing lower extremity fracture surgery. Substance use and abuse were the main risk factors for increased perioperative opioid prescription filling. Providers should recognize these risk factors for increased use and be judicious when prescribing opioids. Enhanced patient education, increased nonopioid pain management strategies, and referral for substance use and abuse treatment may be helpful for these patients. LEVEL OF EVIDENCE: Level III.

The Impact of Mental Health and Substance Use on Opioid Demand After Hip Fracture Surgery.

INTRODUCTION: Mental health and substance use and abuse disorders have been associated with poor patient-reported outcomes. Despite the prevalence of hip fractures in the United States, the relationship between opioid demand and these factors in hip fracture surgery is not well understood. The purpose of this study is to describe opioid filling volume and rates after hip fracture surgery and to identify mental health risk factors for increased demand. The study hypothesis is that psychiatric comorbidities such as depression and psychoses as well as substance use and abuse indicators such as pre-op opioid dependence, drug, alcohol, and tobacco abuse would be associated with increased perioperative opioid demand. METHODS: This is a retrospective cohort study of 40,514 patients undergoing surgical fixation of hip fractures using a commercially available insurance database. The primary patient-level outcome was filled opioid prescription volume in oral morphine milliequivalents converted to oxycodone 5-mg equivalents up to 1-year post-op. Adjusted measures of overall quantities filled and refill rates were assessed with multivariable main effects linear and logistic regression models. RESULTS: Twenty four thousand four hundred forty-one of 40,514 patients (60.3%) filled opioid prescriptions within 7 days pre-op to 1-year post-op. Patients filling prescriptions filled a mean of 187.7 oxycodone 5-mg equivalents. Sixteen thousand five hundred seventy-seven patients (41.1%) filled two or more opioid prescriptions within 7 days pre-op to 1-year post-op. Fifteen thousand two hundred seventy-nine patients (37.7%) filled an opioid prescription between 3 months post-op and 1-year post-op, and 8,502 patients (21%) filled an opioid prescription between 9 months post-op and 1-year post-op. In multivariable models, age, pre-op opioid filling, depression, tobacco abuse, and drug abuse were risk factors significantly associated with increased perioperative opioid filling. Psychoses had a mixed effect on outcomes with decreased early perioperative filling and increased late perioperative filling. Pre-op opioid filling had the largest impact on perioperative opioid demand. DISCUSSION: Pre-op opioid filling and drug abuse were the main mental health-related drivers of increased perioperative opioid prescription filling. Depression, psychoses, alcohol abuse, and tobacco abuse had small effects on prescription filling. These results can help identify patients at risk for increased opioid demand who may benefit from additional counseling, maximizing alternative pain management strategies, and possible referral to pain management specialists. LEVEL OF EVIDENCE: Level III, retrospective, prognostic cohort study.
