Trajectories of pain and opioid use up to one year after surgery: analysis of a European registry.

BACKGROUND: Long-term opioid use after surgery is a crucial healthcare problem in North America. Data from European hospitals are scarce and differentiation of chronic pain has rarely been considered. METHODS: In a mixed surgical cohort of the PAIN OUT registry, opioid use and chronic pain were evaluated before surgery, and 6 and 12 months after surgery (M6/M12). Subgroups with or without opioid medication and pre-existing chronic pain were analysed. M12-chronic pain was categorised as chronic postsurgical pain (CPSP) meeting the ICD-11 definition, chronic pain related to surgery not meeting the ICD-11 definition, and chronic pain unrelated to surgery. Primary endpoint was the rate of M12 opioid users. Variables associated with M12 opioid use and patient-reported outcomes were evaluated. RESULTS: Of 2326 patients, 5.5% were preoperative opioid users; 4.4% and 3.5% took opioids at M6 and M12 (P<0.001). Chronic pain before operation and at M6/M12 was reported by 41.2%, 41.8%, and 34.7% of patients, respectively (P<0.001). The rate of M12 opioid users was highest in group unrelated (22.3%; related 8.3%, CPSP 1.5%; P<0.001). New opioid users were 1.1% (unrelated 7.1%, related 2.3%, CPSP 0.7%; P<0.001). M12 opioid users reported more pain, pain-related physical and affective interference, and needed more opioids than non-users. The predominant variable associated with M12 opioids was preoperative opioid use (estimated odds ratio [95% confidence interval]: 28.3 [14.1-56.7], P<0.001). CONCLUSIONS: Opioid use was low in patients with CPSP, and more problematic in patients with chronic pain unrelated to surgery. A detailed assessment of chronic pain unrelated or related to surgery or CPSP is necessary. CLINICAL TRIAL REGISTRATION: NCT02083835.

Association of Prehabilitation With Postoperative Opioid Use in Colorectal Surgery: An Observational Cohort Study.

INTRODUCTION: Preoperative optimization programs have demonstrated positive effects on perioperative physical function and surgical outcomes. In nonsurgical populations, physical activity and healthy diet may reduce pain and pain medication requirement, but this has not been studied in surgical patients. Our aim was to determine whether a preoperative diet and exercise intervention affects postoperative pain and pain medication use. METHODS: Patients undergoing abdominal colorectal surgery were invited to participate in a web-based patient engagement program. Those enrolling in the first and third time periods received information on the standard perioperative pathway (enhanced recovery after surgery [ERAS]). Those enrolling in the second time period also received reminders on nutrition and exercise (PREHAB + ERAS). The primary outcome was postoperative inpatient opioid use. The secondary outcomes were inpatient postoperative pain scores and nonopioid pain medication use. RESULTS: The ERAS and PREHAB + ERAS groups were similar in demographic and operative characteristics. Subgroup analysis of patients who activated their accounts demonstrated that the two groups had similar average maximum daily pain scores, but the PREHAB + ERAS group (n = 158) used 15.9 fewer oral morphine equivalents per postoperative inpatient day than the ERAS group (n = 92), representing a 30% decrease (53 mg versus 37.1 mg, P = 0.04). The two groups used comparable amounts of acetaminophen, gabapentin, and ketorolac. Generalized linear models demonstrated that PREHAB + ERAS, minimally invasive surgery, and older age were associated with lower inpatient opioid use. CONCLUSIONS: Access to a web-based preoperative diet and exercise program may reduce inpatient opioid use after major elective colorectal surgery. Further studies are necessary to determine whether the degree of adherence to nutrition and physical activity recommendations has a dose-dependent effect on opioid use.

Factors associated with persistent opioid use 6-12 months after primary total knee arthroplasty.

Persistent pain following knee arthroplasty occurs in up to 20% of patients and may require ongoing analgesia, including extended opioid administration. A comprehensive secondary analysis was performed from results of a study that considered persistent postoperative pain in 242 patients who underwent unilateral knee arthroplasty using a standardised enhanced recovery programme. Opioid prescribing for 12 months before and 12 months after surgery was evaluated and converted to oral morphine equivalents. Demographic, functional, psychological and pain questionnaires were completed along with quantitative sensory testing and genetic analysis. Forty-nine percent of patients had at least one opioid prescription in the 12 months before surgery. Opioid prescriptions were filled in 93% of patients from discharge to 3 months and in 27% of patients ≥6 months after surgery. Persistent opioid use ≥6 months after surgery was strongly associated with pre-operative opioid use (RR 3.2, p < 0.001 (95%CI 1.9-5.4)). The median (IQR [range]) oral morphine equivalent daily dose was 3.6 (0.9-10.5 [0-100.0]) mg pre-operatively, 35.0 (22.5-52.5 [4.6-180.0]) mg in hospital, 12.8 (5.1-24.8 [0-57.9]) mg from discharge to 3 months and 5.9 (4.5-12.0 [0-44.5]) mg at ≥6 months following surgery. Predictors of increased daily oral morphine equivalent ≥6 months after surgery included increased average daily oral morphine equivalent dose compared with previous values (lag), increased body mass index and three or more comorbid pain sites. Persistent opioid use was not associated with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain (RR 1.003, p = 0.655, 95%CI 0.65-1.002) or WOMAC function (RR 1.001, p = 0.99, 95%CI 0.99-1.03) outcomes 6 months after surgery. There was no association between persistent opioid use and pre-operative quantitative sensory testing results or psychological distress. Pre-operatively, patients with a higher body mass index, more comorbid pain sites and those who had filled an opioid prescription in the last 12 months, were at increased risk of persistent opioid use and a higher oral morphine equivalent daily dose ≥ 6 months after surgery. Strategies need to be developed to limit dose and duration of persistent opioid use in patients following knee arthroplasty surgery.

Machine-learning model successfully predicts patients at risk for prolonged postoperative opioid use following elective knee arthroscopy.

PURPOSE: Recovery following elective knee arthroscopy can be compromised by prolonged postoperative opioid utilization, yet an effective and validated risk calculator for this outcome remains elusive. The purpose of this study is to develop and validate a machine-learning algorithm that can reliably and effectively predict prolonged opioid consumption in patients following elective knee arthroscopy. METHODS: A retrospective review of an institutional outcome database was performed at a tertiary academic medical centre to identify adult patients who underwent knee arthroscopy between 2016 and 2018. Extended postoperative opioid consumption was defined as opioid consumption at least 150 days following surgery. Five machine-learning algorithms were assessed for the ability to predict this outcome. Performances of the algorithms were assessed through discrimination, calibration, and decision curve analysis. RESULTS: Overall, of the 381 patients included, 60 (20.3%) demonstrated sustained postoperative opioid consumption. The factors determined for prediction of prolonged postoperative opioid prescriptions were reduced preoperative scores on the following patient-reported outcomes: the IKDC, KOOS ADL, VR12 MCS, KOOS pain, and KOOS Sport and Activities. The ensemble model achieved the best performance based on discrimination (AUC = 0.74), calibration, and decision curve analysis. This model was integrated into a web-based open-access application able to provide both predictions and explanations. CONCLUSION: Following appropriate external validation, the algorithm developed presently could augment timely identification of patients who are at risk of extended opioid use. Reduced scores on preoperative patient-reported outcomes, symptom duration and perioperative oral morphine equivalents were identified as novel predictors of prolonged postoperative opioid use. The predictive model can be easily deployed in the clinical setting to identify at risk patients thus allowing providers to optimize modifiable risk factors and appropriately counsel patients preoperatively.

Optimization of postoperative opioid prescriptions in gynecologic oncology: Striking a balance between opioid reduction and pain control.

OBJECTIVE: To implement a quality-improvement initiative to assess the impact various patient and procedural factors have on postoperative opioid use. To develop a tailored opioid prescribing algorithm for gynecologic oncology patients. METHODS: A retrospective cohort study was performed of patients who underwent a laparoscopy or laparotomy procedure for a suspected or known gynecologic malignancy between 3/2019-9/2020. Patients were assessed preoperatively for the presence of suspected risk factors for opioid misuse (depression, anxiety, chronic pain, current opioid use, or substance abuse). Patients completed a 30-day postoperative questionnaire assessing for total opioid pill use and refills requests. Multivariate models were developed to estimate the independent effect of sociodemographic characteristics, risk factors for opioid misuse and procedural factors on patient reported postoperative opioid use. RESULTS: A total of 390 patients were analyzed. Thirty-nine percent (N = 151/390) of patients reported not using opioids after discharge and 5% (N = 20/390) received an opioid refill. For both minimally invasive procedures and laparotomy procedures, body mass index, comorbidities, intraoperative or postoperative complications and final diagnosis of malignancy were not associated with the amount of opioid consumption. However, younger age and history of risk factors for opioid misuse significantly impacted postoperative opioid use. In multivariate analysis, age (p = 0.038) and risk factors (p < 0.001) remained significant after controlling for other factors. CONCLUSIONS: Two out of every five patients did not use opioids after surgery. Younger patients and those with risk factors for opioid misuse need a tailored approach to prescribing opioids to balance the need for adequate pain control with the risk of misuse.

Effect of preoperative intravenous vs oral acetaminophen on postoperative opioid consumption in an enhanced recovery after surgery (ERAS) program in patients undergoing open gynecologic oncology surgery.

OBJECTIVE: Both intravenous (IV) and oral acetaminophen provide effective opioid-sparing analgesia after surgery when used as part of a multimodal preemptive pain management strategy. The purpose of this study was to compare postoperative opioid consumption in patients undergoing open gynecologic oncology surgery who received preoperative IV vs oral acetaminophen within an enhanced recovery after surgery (ERAS) program. METHODS: Retrospective data were collected on consecutive patients undergoing open gynecologic oncology surgery from May 1, 2016 to February 28, 2018 in patients receiving either 1 g IV or oral acetaminophen preoperatively. Patients were given a preoperative multimodal analgesia regimen including acetaminophen, celecoxib, pregabalin and tramadol. The primary outcomes were morphine equivalent daily doses (MEDD) on postoperative days (POD) 0 and 1. Secondary outcomes included highest patient-reported pain score in the post-anesthesia care unit (PACU) and intraoperative MEDD. Regression models adjusted by matched pairs were fit to estimate the average treatment effect of IV vs oral acetaminophen on MEDD. RESULTS: Of 353 patients, 178 (50.4%) received IV acetaminophen and 175 (49.6%) received oral acetaminophen. When balancing across the matched samples, there was no difference in postoperative MEDD for POD 0 between the IV and oral acetaminophen groups (Beta = -1.11; 95% CI: -4.83 to 2.60; p = 0.56). On POD 1, there was no difference between the IV and oral groups (Beta = 2.24; 95% CI: -2.76 to 7.25; p = 0.38). CONCLUSIONS: There was no difference in postoperative opioid consumption between patients receiving preoperative IV or oral acetaminophen within an ERAS program for patients undergoing open gynecologic oncology surgery.

Opioid Prescription Usage after Benign Gynecologic Surgery: A Prospective Cohort Study.

STUDY OBJECTIVE: To compare the amount of opioids (tablets and morphine milligram equivalents [MMEs]) prescribed by physicians and used by patients after benign gynecologic surgery. DESIGN: Prospective cohort study. SETTING: Tertiary center: main hospital operating room and outpatient surgery center. PATIENTS: Women undergoing benign gynecologic surgery. INTERVENTIONS: Major and minor gynecologic surgeries. MEASUREMENTS AND MAIN RESULTS: The surgery groups were minor laparoscopy (Minor), major minimally invasive (Major), and laparotomy (Laparotomy). Demographic, medical, and surgical data were abstracted from electronic medical records. On postoperative day (POD) 7, women completed a telephone survey describing pain levels, prescription use, and satisfaction with pain control. Patients who continued to use opioids for pain relief were surveyed on POD 14. If use continued, patients were surveyed again on POD 28. The primary outcome was amount of opioid prescribed compared with opioid used. Of 193 screened participants 172 were enrolled (89%), and data were analyzed for 154 (90%): 59 (38%) Major, 71 (56%) Minor, and 24 (16%) Laparotomy. The median number of tablets and MMEs prescribed was lowest for the Minor group (Minor, 24 tablets; Major, 30 tablets; Laparotomy, 30 tablets [p <.01]; Minor, 150 MMEs; Major, 225 MMEs; Laparotomy, 225 MMEs [p = .01]). We found no difference in the number of tablets (Minor, 8; Major, 8; Laparotomy, 9; p = .77) or MMEs used (Minor, 45 MMEs; Major, 45 MMEs; Laparotomy, 55 MME; p = .81) between the groups. On POD 7 there was no difference in median numerical rating scale pain scores (Minor, 3; Major, 2; Laparotomy, 2; p = .07) or satisfaction with analgesia on POD 7 (p = .44), 14 (p = .87), and 28 (p = .18). Patients with prior chronic pain used more total amounts of opioids (68 MME vs 30 MME, p <.01) and were more likely to require opioid refill (odds ratio, 10.4; 95% confidence interval, 1.3-83.6) compared with those without a similar history. CONCLUSION: In this cohort, gynecologic surgeons prescribed nearly 3 times more opioid tablets and MMEs than was used by patients despite patients reporting similar levels of pain after minor and major surgeries.

Disordered Sleep in Adolescents Recovering From Surgery.

BACKGROUND AND OBJECTIVES: Sleep is essential for postoperative recovery. Prescription opioid can be associated with disordered sleep. There is little research on sleep patterns among adolescents using opioids for postoperative pain. Our objective was to identify factors associated with disordered sleep among adolescents undergoing surgery. METHODS: Prospective single-center survey-based cohort study of adolescents (13-20y) undergoing eight surgeries commonly associated with an opioid prescription. Participants completed a preoperative survey measuring clinical, mental health, and sociodemographic factors, and postoperative surveys at 30- and 90-days. All surveys administered the Sleep Problems Questionnaire. Repeated measures logistic regression evaluated the impact of surgery on worsening postoperative sleep scores. Linear change model evaluated sleep score trajectories; Poisson regression identified the impact of preoperative disordered sleep on opioid use. RESULTS: Overall, 167 adolescents (median 15y, 64% female) were included. Twenty-seven (16.2%) reported disordered sleep preoperatively and 41 (24.6%) postoperatively. Prescription opioid use was not associated with development of disordered sleep postoperatively (OR:1.33; 95% CI:0.38-4.68). Adolescents were 2.20 (95% CI:1.42-3.40) times more likely to report disordered sleep postoperatively. Preoperative disordered sleep, time after surgery, and mental health comorbidities were associated with worsening postoperative sleep score trajectories (p < 0.01). Adolescents with preoperative disordered sleep were not more likely to use opioids (OR:2.56, 95% CI:0.76-8.63, p = 0.13) nor did they use more pills (IRR:0.84, 95% CI:0.62-1.15, p = 0.27). CONCLUSIONS: Adolescents were more likely to report disordered sleep postoperatively. Preoperative disordered sleep and mental health comorbidities, but not prescription opioid use, were associated with worsening sleep after surgery. Future efforts to improve adolescent postoperative sleep should address baseline disordered sleep and mental health comorbidities. LEVEL OF EVIDENCE: Level II. TYPE OF STUDY: Prospective cohort study.

Standardization of Antibiotic Management and Reduction of Opioid Prescribing in Pediatric Complicated Appendicitis: A Quality Improvement Initiative.

BACKGROUND: Appendicitis is one of the most common pediatric surgical procedures in the United States. However, wide variation remains in antibiotic prescribing and pain management across and within institutions. We aimed to minimize variation in antibiotic usage and decrease opioid prescribing at discharge for children with complicated appendicitis by implementation of a quality improvement (QI) initiative. METHODS: On December 1st, 2021, a QI initiative standardizing postoperative care for complicated appendicitis was implemented across a tertiary pediatric healthcare system with two main surgical centers. QI initiative focused on antibiotic and pain management. An extensive literature search was performed and a total of 20 articles matching our patient population were critically appraised to determine the best evidence-based interventions to implement. Antibiotic regimen included: IV or PO ceftriaxone/metronidazole immediately post-operatively and transition to PO amoxicillin-clavulanic acid for completion of 7-day total course at discharge. Discharge pain control regimen included acetaminophen, ibuprofen, as needed gabapentin, and no opioid prescription. Guideline compliance were closely monitored for the first six months following implementation. RESULTS: In the first 6-months post-implementation, compliance with use of ceftriaxone/metronidazole as initial post-operative antibiotics was 75.6 %. Transition to PO amoxicillin-clavulanic acid prior to discharge increased from 13.7 % pre-implementation to 73.7 % 6-months post-implementation (p < 0.001). Compliance with a 7-day course of antibiotics within the first 6-months post-implementation was 60 % across both sites. After QI intervention, overall opioid prescribing remained at 0 % at one surgical site and decreased from 17.6 % to 0 % at the second surgical site over the study timeframe (p < 0.001). CONCLUSION: Antibiotic use can be standardized and opioid prescribing minimized in children with complicated appendicitis using QI principles. Continued monitoring of the complicated appendicitis guideline is needed to assess for further progress in the standardization of post-operative care. STUDY TYPE: Quality improvement. LEVEL OF EVIDENCE: Level III.

Higher Pain Catastrophizing and Preoperative Pain is Associated with Increased Risk for Prolonged Postoperative Opioid Use.

BACKGROUND: Prolonged postoperative opioid use (PPOU) is considered an unfavorable post-surgical outcome. Demographic, clinical, and psychosocial factors have been associated with PPOU, but methods to prospectively identify patients at increased risk are lacking. OBJECTIVES: Our objective was to determine whether an individual or a combination of several psychological factors could identify a subset of patients at increased risk for PPOU. STUDY DESIGN: Observational cohort study with prospective baseline data collection and passive outcomes data collection. SETTING: A single VA medical center in the United States. METHODS: Patients were recruited from a preoperative anesthesia clinic where they were undergoing evaluation prior to elective surgery, and they completed a survey before surgery. The primary outcome was PPOU, defined as outpatient receipt of a prescribed opioid 31 to 90 days after surgery as determined from pharmacy records. Primary covariates of interest were pain catastrophizing, self-efficacy, and optimism. Additional covariates included social and demographic factors, pain severity, medication use, depression, anxiety, and surgical fear. RESULTS: Of 123 patients included in the final analyses, 30 (24.4%) had PPOU. In bivariate analyses, preoperative opioid use and preoperative nonsteroidal anti-inflammatory drug use were significantly associated with PPOU. The combination of high pain catastrophizing and high preoperative pain (OR 3.32, 95% CI 1.41 - 7.79) was associated with higher odds of PPOU than either alone, and the association remained significant after adjusting for preoperative opioid use (OR 2.56, 95% CI 1.04 - 6.29). LIMITATIONS: Patients were recruited from a single site, and the sample was not large enough to include potentially important variables such as procedure type. CONCLUSIONS: A combination of high pain catastrophizing and high preoperative pain has the potential to be a clinically useful means of identifying patients at elevated risk of PPOU.

Patient-specific factors, but neither regional anesthesia nor hip-specific cryotherapy, predict postoperative opioid requirements after hip arthroscopy for femoroacetabular impingement (FAI) syndrome.

Background: We sought to determine whether regional nerve block, cryotherapy variant, or patient-specific factors predict postoperative opioid requirements and pain control following hip arthroscopy. Methods: 104 patients underwent hip arthroscopy with (n = 31) or without (n = 73) regional block and received cryotherapy with a universal pad [joint non-specific; no compression (n = 60)] or circumferential hip/groin wrap with intermittent compression (n = 44). Outcomes included total opioid prescription amounts, requests for refills, and unplanned clinical encounters for postoperative pain within 45 days of surgery. Multivariate modeling was used to determine the effect of perioperative regional nerve block and type of cryotherapy device on outcomes after adjusting for patient demographics, previous opioid use, mental health disorder history, and surgery length. Results: The average amount of 5 mg oxycodone pill equivalents prescribed within 45 days of surgery was 40.5 (SD 14.8); 36% requested refills, 20% presented to another physician, and 21% called the surgeon's office due to pain. Neither the hip-specific cryotherapy pad nor regional block was predictive of opioid amounts prescribed, refill requests, or unplanned clinical encounters due to pain. Refill requests within 45 days were more common with baseline opioid use (p < 0.001), increased age (p = 0.007), and mental health disorder history (p = 0.008). Total opioid amounts prescribed within 45 days were higher with workers compensation (p = 0.03), a larger initial opioid prescription (p < 0.001), baseline opioid use (p < 0.001), history of mental health disorder (p = 0.02), and increased age (p = 0.02). Together, these variables explained 61% of the variance in opioid amounts prescribed. Conclusion: Patient factors are strong predictors of postoperative opioid requirements after hip arthroscopy. Postoperative opioid prescription amounts, opioid refill requests, and pain-related calls or office visits were not affected by use of a perioperative regional nerve block or type of cryotherapy delivery system. Level of evidence: III, retrospective cohort study.

Predictors of patient post-discharge opioid use after cesarean delivery: a prospective study.

BACKGROUND: The opioid crisis is a public health emergency in the United States of America. It is important to understand factors associated with outpatient opioid use. Our primary aim was to assess post-cesarean outpatient opioid use. The secondary aim was to identify characteristics associated with use. METHODS: We conducted a prospective cohort analysis of women who underwent cesarean delivery at an urban academic center. Phone surveys were done on post-discharge days three, seven, and 14. The primary outcome was post-discharge opioid use. RESULTS: Of 205 eligible patients contacted, 190 (91%) agreed to participate and 173 (84%) participated in all three surveys. Median amount of opioid prescribed was 75 mg morphine equivalents (MME) (interquartile range 60-113) and participants used a median of 15 MME (0-53) by discharge day 14. Most patients (139/190) filled their opioid prescription but 42% (80/190) did not consume the opioids prescribed. Outpatient opioid use was associated with increased in-hospital opioid consumption (P=0.0003), gravidity (P=0.003), parity (P=0.004) and number of previous cesarean deliveries (P=0.02). Higher amounts of in-hospital opioid use (P=0.0004), higher gravidity (P=0.02), higher outpatient pain scores (>3/10, P=0.01), and poor pain control (P=0.04) were associated with consuming all prescribed opioids. Patients used opioids for a median of two days post-discharge. Use of non-opioid pain medication was not associated with opioid use. CONCLUSION: Opioids were prescribed in excess of consumption and many patients did not use any opioids. Next steps include developing a prescribing algorithm to incorporate factors we found predictive of opioid use.

Postoperative Prescriptions and Corresponding Opioid Consumption After Septoplasty or Rhinoplasty.

The objective of our study was to assess the relationship between postoperative opioid prescribing patterns and opioid consumption among patients who underwent septoplasty or rhinoplasty. A chart review of patients who underwent either septoplasty or rhinoplasty by 3 surgeons between July 2016 and June 2017 was performed, and pertinent clinical data were collected including the amount of narcotic pain medications prescribed. A telephone interview was then conducted to assess opioid usage and pain control regimen postoperatively. The number of opioid tablets prescribed and the number consumed were converted to total morphine milligram equivalent (MME) for uniform comparison. A total of 75 patients met the inclusion criteria, and 64 completed the telephone survey. Among these 64 patients, the mean (standard deviation [SD]) prescribed MME was 289.7 (101.3), and the mean (SD) consumed MME was 100.6 (109). Similarly, the mean (SD) number of opioid tablets prescribed was 42.4 (9.7), and the mean number of tablets consumed was 14.7 (16.3). Gender, procedure performed (septoplasty or rhinoplasty), use of Doyle splints, and surgeon were not associated with the amount of opioids prescribed or used. Subjective pain control was the only factor associated with an increase in opioid use (P = .0288). There was an overabundance of opioid pain medications prescribed compared to the amount consumed for pain control after septoplasty or rhinoplasty. Abuse of prescription opioids represents an important component of the nation's opioid crisis. Surgeons must be cognizant of the problem and adjust prescribing practices accordingly.

Risk factors for postoperative voiding dysfunction following surgery for pelvic organ prolapse.

OBJECTIVE: Short-term postoperative voiding dysfunction (POVD) is common in women undergoing surgery for pelvic organ prolapse. It results in increased catheter burden for patients and health services, and catheter-associated urinary tract infections (CAUTIs), thereby escalating the overall cost of treatment. Our aim was to determine the risk factors for voiding dysfunction following surgery for POP in our unit. STUDY DESIGN: A retrospective case-control study conducted in a tertiary center in the U.K. The study cohort included all women who underwent surgery for pelvic organ prolapse between March 2017 and March 2019 and had a failed trial without catheter (TWOC). The control group comprised consecutive women on the surgical database who passed TWOC. Relevant data, including demographic details, past medical history, intraoperative and postoperative factors, were collected. We used the Chi-square test to calculate the statistical significance and multiple logistic regression analysis using SPSS software to identify the risk factors. RESULTS: 286 surgeries were performed. After exclusion, 43 patients were included in each group. Baseline demographics were similar in both groups. The incidence of POVD was 15%, and none of our patients had long-term voiding problems. Logistic regression analysis identified five risk factors - advanced pelvic organ prolapse (OR = 2.654, p = 0.029), comorbidities (OR = 4.583, p = 0.019), preoperative anticholinergics and/or antidepressants (OR = 4.440, p = 0.004), sacrospinous hysteropexy/colpopexy (OR = 2.613, p = 0.041) and postoperative opioid use (OR = 3.529, p = 0.004). CONCLUSION: We identified five risk factors to recognize the women who would benefit from advanced counseling and management plan following surgery for pelvic organ prolapse.

Recovery after enhanced versus conventional care laparoscopic hysterectomy performed in the afternoon: A randomized controlled trial.

OBJECTIVE: To compare enhanced recovery after surgery (ERAS) and conventional care (CC) protocols on outcomes of laparoscopic hysterectomy (LH) performed in the afternoon. METHODS: A single-center randomized controlled trial was conducted on 120 women undergoing LH who were randomly divided into the intervention group (IG; n=60) and control group (CG; n=60). Women in the IG were treated according to the ERAS protocol and those in the CG according to the CC protocol. The primary outcome was the length of hospitalization. Secondary outcomes were postoperative opioid use, postoperative pain and emesis, complications, operative bleeding, and time. RESULTS: More women discharged during 24 hours in the IG than in the CG (88% vs 55%, P<0.001). The time to actual discharge (19 vs 22 hours, P<0.001) and ready-to-discharge time (15 vs 21 hours, P<0.001) were shorter and the use of oxycodone was lower (0 mg [0-0 vs 2.5 mg [0-10], P<0.001) in the IG than in the CG, respectively. Otherwise, no other significant differences between the groups were observed. The follow-up time was one month. CONCLUSION: The ERAS protocol reduces hospital stay and decreases the use of opioids with no impairment in surgical outcome of LH. ClinicalTrials.gov: NCT03828981.

The role of intravenous acetaminophen in post-operative pain control in head and neck cancer patients.

OBJECTIVE: This study investigated the role of intravenous acetaminophen for alleviation of postoperative pain after surgical resection of head and neck cancers. METHODS: A single-center study was conducted, which investigated a prospective group of 48 participants who underwent surgery between April 2016 and May 2017 and postoperatively received scheduled IV acetaminophen (1 g every 6 hours for 4 doses) plus the standard opioid PCA and breakthrough narcotics. These were compared to a similar retrospective cohort of 51 patients who had surgery between January 2014 to March 2015 and only received an opioid patient controlled analgesia (PCA) pump and breakthrough narcotics. Outcome measures included averaged pain scores, total amount of narcotics received (in morphine equivalents), and number of PCA attempts measured in 8-hour intervals over the first 24 hours, as well as duration of PCA and length of stay. Statistical measures included descriptive analysis and gamma regression analysis. RESULTS: The acetaminophen group achieved equally low pain scores (0.8 ± 1.2 vs. 1.0 ± 1.3, P = .408) with significantly less total narcotics in the first 8 hours after surgery (13.5 ± 13.3 vs. 22.5 ± 21.5 MEs, P = .014). This group had a significantly decreased length of stay (7.8 ± 4.6 vs. 10.6 ± 7.6 days, P = .03). CONCLUSION: This study demonstrates that intravenous acetaminophen may play a role in reducing the total narcotic requirement in the first 8 hours after surgery and contribute to a decreased length of stay and potentially decrease cost to the patient and hospital overall. Future research should be aimed at comparing these groups in a randomized control study/setting. LEVEL OF EVIDENCE: 3.

Perioperative opioid administration in children with and without developmental delay undergoing outpatient dental surgery.

STUDY OBJECTIVE: Prior research has indicated that children with developmental delay (DD) experience qualitative and quantitative differences in health care (Boulet et al., 2009). In the perioperative setting, there is concern that children with DD may be more likely to experience postoperative complications including agitation and nausea/vomiting than typically developing patients (TDP). Differences in the administration and dosage of perioperative opioids may contribute to this, however, empirical investigations are lacking. The purpose of this research was to compare the experience of postoperative nausea/vomiting and agitation, as well as to examine perioperative opioid administration, among children with DD as compared to TDP. DESIGN: Retrospective original research. SETTING: Operating room, postanesthesia care unit. PATIENTS: 1145 patients (1-20.9years, ASA I-III, 23.9% with a history of DD) who had undergone outpatient dental surgery involving extraction/restorations under general anesthesia. MEASUREMENTS: Data was obtained and analyzed from the medical records of both DD and TDP across a five-year period. Data included the experience of agitation, nausea/vomiting, as well as perioperative medication administration. MAIN RESULTS: Postoperative agitation and nausea/vomiting did not differ significantly between the DD and TDP groups. Children with DD were significantly less likely to receive opioids during both the intra and postoperative period (χ2=10.02, p=0.001 and χ2=8.08, p=0.003, respectively). Further, higher dosage of intraoperative opioids was predictive of reduced administration of postoperative opioids among TDP; however, no significant association was observed between the dosage of intraoperative opioids and administration of postoperative opioids in the DD group. CONCLUSIONS: Children with DD experience similar rates of postoperative complications including nausea/vomiting and agitation as TDP. DD children were less likely to receive both intra and postoperative opioids than TDP. Importantly, while the dosage of intraoperative opioids was predictive of administration of postoperative opioids in the TDP group, this was not the case for the DD group. Clinical implications are discussed.
