Does Postoperative Gabapentin Administration Reduce Opioid Consumption after Foot and Ankle Surgery?

Category: Ankle; Hindfoot; Midfoot/Forefoot Introduction/Purpose: Prescription opioids are commonly used to control postoperative pain in foot and ankle surgery, but present potentially detrimental side effects including sedation, respiratory depression, and addiction. In foot and ankle surgery, pain is a common cause of delayed hospital discharge and decreased willingness to move, thereby slowing recovery. Gabapentin acts by decreasing lesion-induced hyperexcitability of posterior horn neurons and central sensitization, and has been explored as a potential addition to patients’ pain regimen. Although studies have previously assessed the effect of gabapentin on pain relief, to our knowledge none have evaluated whether gabapentin is effective in opioid consumption reduction beyond the immediate postoperative period. The purpose of this study is to assess whether gabapentin acts synergistically to improve postoperative pain among patients undergoing foot and ankle surgery. Methods: Patients from a single institution who underwent elective foot and ankle surgery were identified using CPT codes 27700, 27702, 27870, 28705, 28715, 28725, 28730, and 28740. All patients prescribed opioids postoperatively were included. A retrospective chart review was conducted for each patient to identify prescription dose, number of pills, date in which prescription was filled, and dates of refills for oxycodone, hydrocodone, oxycodone-acetaminophen, hydrocodone-acetaminophen, tramadol, and gabapentin. Medication information was collected only for prescriptions by the operating surgeon, nurse practitioner, physician assistant, resident, or fellow which were pertinent to the foot/ankle surgery performed; prescriptions from other services or providers were not included in order to ensure that the medications prescribed were specific to postoperative pain. Opioid quantities were converted to morphine equivalents and compared at various time intervals between patients who were prescribed only opioids, and patients who were prescribed opioids and gabapentin. Results: Among patients not taking opioids or gabapentin preoperatively, total morphine equivalents prescribed was significantly less among patients prescribed postoperative gabapentin (177.3 OME) in comparison to those prescribed only opioids (442.2 OME) (p=0.0018) in the 3-6 week postoperative interval. When all patients were analyzed, including those taking preoperative opioids or gabapentin, patients who received postoperative gabapentin were also prescribed significantly fewer OME at weeks 1-2 (p= 0.0270), weeks 3-6 (p = 0.0006), and weeks 7 - 12 (p = 0.0149). Conclusion: Gabapentin may be effective in reducing postoperative opioid consumption beyond the immediate postoperative period among elective foot and ankle surgery patients. Prospective clinical trials are warranted to further validate these results. [Table: see text][Table: see text][Table: see text]

Opioid quantities were converted to morphine equivalents and compared at various time intervals between patients who were prescribed only opioids, and patients who were prescribed opioids and gabapentin. Results: Among patients prescribed gabapentin plus opioids, total opioids prescribed (in morphine equivalents, OME) was 68.33, 221.25, 87.50, and 400.83 at weeks 1-2, 3-6, 7-12, and greater than 12, respectively. Although not statistically significantly different, patients prescribed only opioids had greater average amounts of opioids prescribed at all time intervals, equaling 98.34 OME, 553.52 OME, 540.53 OME, and 766.25 OME at weeks 1-2, 3-6, 7-12, and greater than 12, respectively. When excluding patients taking opioids preoperatively, total morphine equivalents prescribed was significantly less among patients prescribed gabapentin (196.94 OME) in comparison to those prescribed only opioids (457.41 OME) (p=0.0255). Conclusion: The findings of this study suggest that gabapentin may be effective in reducing postoperative opioid consumption beyond the immediate postoperative period among elective foot and ankle surgery patients. Gabapentin may be particularly beneficial within the three to six week postoperative period. Prospective clinical trials are warranted to further validate these results.

Category: Ankle; Other Introduction/Purpose: The purpose of this study was to perform a systematic review of the current literature assessing the management of pain with various block techniques in the perioperative period during elective foot and ankle surgery. Methods: A review of the literature was performed according to the PRISMA guidelines. Medline, Embase, and Cochrane databases were searched on October 1, 2019. Studies were identified by using synonyms for ‘foot’, ‘ankle’, ‘pain management’, ‘opioid’ and ‘nerve block’. Inclusion criteria were studies that 1) reported and compared the outcomes following various types of peripheral nerve blocks in in foot and ankle surgery, 2) were published in the English language, and 3) were published within the last 10 years. Results: Twenty-four articles evaluating 4,640 patients were included. Sixty-seven percent were randomized controlled trials, 17% were prospective comparison studies, and 17% were retrospective comparison studies. Nerve block techniques included: femoral, adductor canal, sciatic, popliteal, saphenous, and ankle. Ropivacaine and bupivacaine were most commonly utilized. Postoperative opioid consumption and postoperative pain levels were reduced with use of PNB when compared with systemic/local anesthesia, in patients receiving combined popliteal/femoral block, and in patients receiving continuous infusion popliteal block [Table 1, Table 2]. Studies demonstrated higher satisfaction with PNB, continuous infusion, and dual injections [Table 3]. One study reported 7% neurologic related complication risk and demonstrated a higher complication rate when with popliteal versus ankle block. All other studies were equivocal or failed to mention complications. Conclusion: Optimal pain management for elective foot and ankle surgery remains controversial and an ideal protocol from a risk-benefit perspective regarding use of PNB has yet to be established. Our study demonstrates improvements in postoperative pain levels, opioid consumption, and length of stay in patients receiving a PNB when compared with systemic anesthesia. Combined PNB and dual catheter administration may improve outcomes. Unfortunately, little data has been published on risks and tradeoffs in order to help guide patients and surgeons with a well informed shared decision making model. Future studies are needed to better clarify any respective tradeoffs to these options. [Table: see text]

Category: Opioid consumption rate and risk factors investigation after foot and ankle surgery Introduction/Purpose: The rapid increase in the consumption of prescription opioids has become one of the leading medical, economical, and sociological burdens in North America. In the United States, orthopedic surgery is the fourth leading specialty in the number of opioids prescribed, and the largest among surgical specialties. There is insufficient evidence to guide surgeons about appropriate opioid prescription amounts after orthopaedic foot and ankle (F&A) procedures. The aim of this study was to determine the opioid consumption rate after foot and ankle procedures, and to identify patient risk factors associated with higher use. Methods: A total of 535 patients who underwent a F&A surgery performed by one orthopedic surgeon from August 2016 to March 2018 were investigated. The study was approved by our IRB. Each patient received a preoperative discussion about postoperative pain and expectations alongside a standardized handout. At the two-week postoperative visit, the patient-reported amount of consumed opioids was recorded. Prescription details, the amount of opioids taken, refill requests, pain-issue related telephone calls, and additional MD/ED visits were also documented. Patient demographics and co-morbidities, use of regional anesthesia, postoperative inpatient hospitalization, surgery type and severity, and pre-operative opioid use were collected retrospectively. Total amounts of morphine equivalents were calculated and converted into oxycodone 5 mg pills for standardization. P-values of <0.05 were considered significant. Results: Two hundred forty-four patients with a mean age of 50 years (±16.3) and a BMI of 29 (±6.1) were included. Sixty-six (27%) patients underwent a soft tissue procedure alone and 178 (73%) underwent a bony procedure. 225 (92.2%) patients received regional block. Patients reported that they consumed only 51.2% of prescribed pills after a bony procedure and 42.4% after a soft tissue procedure, respectively, which resulted in a total of 4,496.2 left over pills that derived from this study amongst only 244 patients enrolled. There were 11 refill requests (4.5%), two (0.8%) additional MD/ED visits, and 19 (7.8%) telephone calls related to pain. BMI, procedure type, and number of opioids prescribed were positively correlated with the consumption rate (P =.002, P<.001, P<0.001, respectively). Conclusion: BMI, surgery type (bony vs. soft tissue), and a higher number of pills dispensed were correlated with higher use in the postoperative period. After an educative discussion on postoperative pain, patients took 42.4% of the prescribed opioid after soft tissue procedures and 51.2% after bony procedures, resulting in a significant number of unused pills now available to the community. Future guidelines are necessary to improve our postoperative pain management, but this study suggests that current amounts of dispensed pills after orthopaedic F&A procedures are approximately twice as high as necessary.

Background: The rapid increase in the consumption of prescription opioids has become one of the leading medical, economic, and sociological burdens in North America. In the United States, orthopedic surgery is the fourth leading specialty in the number of opioids prescribed, and the largest among all operative specialties. There is insufficient evidence to guide surgeons about appropriate opioid prescription amounts after orthopedic foot and ankle (F&A) procedures. The aim of this study was to determine the opioid consumption rate after foot and ankle procedures and identify risk factors associated with higher use. Methods: A total of 535 patients who underwent foot and/or ankle surgery between August 2016 and March 2018 were included in the study. Each patient received a preoperative discussion about postoperative pain and expectations alongside a standardized handout. At the 2-week postoperative visit, the patients self-reported the amount of consumed opioids. Prescription details, number of opioid pills consumed, refill requests, pain-issue-related telephone calls, and additional physician/emergency department visits were documented. Patient demographics, comorbidities, use of regional anesthesia, hospitalization, surgery type/severity, and preoperative opioid use were collected. A total of 244 patients had a sufficiently complete data set for inclusion in the final cohort. Subjects had a mean age of 50 years (±16.3) and a body mass index (BMI) of 29 (±6.1). Sixty-six (27%) patients underwent a soft tissue procedure alone and 178 (73%) underwent a bony procedure. Results: On average, patients consumed 46.6% of the prescribed pills following a bony procedure and 42.4% after a soft tissue procedure, which resulted in a total of 4496 leftover pills. BMI, procedure type (bony vs soft tissue)/severity, and number of opioids prescribed were positively correlated with elevated consumption rates ( P = .008, P < .001, P < .001, P < .001, respectively). Conclusion: BMI, procedure type, and higher initial pill dispensation correlated with a larger number of consumed pills during the postoperative period. On average, patients took 42.4% of the prescribed opioid after soft tissue procedures and 46.6% after bony procedures, resulting in a significant number of unused pills. Future guidelines are necessary to improve postoperative pain management to prevent narcotic overprescription and minimize the downstream potential for unprescribed community opioid access. Level of Evidence: Level III, retrospective case series, analytic.

Background: Orthopaedic surgeons must consider their postoperative pain management strategies to minimize harm from prescription opioid use. Patients often reference their pain threshold to predict how they will tolerate surgical pain and the need for postoperative analgesia, but the direct relationship between these factors has not yet been studied. The purpose of this study was to determine the relationship between patients’ self-reported pain tolerance and prescription opioid usage after foot and ankle surgery. Methods: This is a retrospective follow-up of a prospective cohort study of adult patients who underwent outpatient foot and ankle surgeries. Patient and procedural demographics, opioid pills dispensed, and opioid pills consumed by the first postoperative visit were obtained. Patients were contacted at a mean of 13.1 ± 4.0 months postoperatively and asked to respond to the qualitative statement “Pain doesn’t bother me as much as it does most people.” Patients were also asked their quantitative pain threshold (0-100), with 0 being “very pain intolerant” and 100 being a “very high pain tolerance,” as well other questions regarding past surgical and narcotic consumption history. Results: Of the 700 survey respondents, the average age was 50.9 years and 34.7% were male. Bivariate analysis determined that predictors of lower postoperative opioid consumption included higher quantitative ( P = .047) and qualitative ( P = .005) pain tolerance scores. Multivariate analysis for the entire cohort demonstrated that higher qualitative pain threshold was associated with lower postoperative opioid consumption ( P = .005) but this did not meet statistical significance as an independent predictor of the top quartile of pill consumers. Conclusion: Assessment of both qualitative and quantitative score of patients’ pain threshold prior to surgery may assist the surgeon in tailoring postoperative pain control. Additionally, asking this question can create an opportunity for educating patients regarding responsible utilization of narcotic medication. Levels of Evidence: Level III

Abstract Introduction Prolonged opioid usage remains a concern in pain management in procedural care. Recent evidence also suggests that a considerable number of patients who were prescribed opioids struggle with transitioning to non-opioid pain medications. As a continuous effort to reduce opioid consumption following burn surgical procedures, our institution recently evaluated methadone administration for burn procedural care in patients with 20–30% total burn surface area (TBSA) requiring excision and grafting. Methods After IRB approval, we performed a retrospective chart review of patients who underwent excision and grafting procedure for 20–30% TBSA burn injuries between January 1, 2019 and June 30, 2020. The following data was evaluated: postoperative opioid consumption, postoperative pain intensity (rated as “No Pain” [NRS=0], “Minor Pain” [NRS 1 to 3], “Moderate Pain” [NRS 4 to 6], “Severe Pain” [NRS 7 to 10]), time to physical therapy and time to hospital discharge. Data was analyzed using chi square/Fisher exact test for categorical variables and t-test/Wilcoxon rank sum test for continuous variables. Results Our preliminary data included 12 patients who met inclusion criteria, of which two patients received methadone administration. Our patient sample consisted of average age of 43 years, 75% male, and 24% TBSA (92% were flame burns). Patients in both methadone and non-methadone groups had no significant differences in medical histories and TBSA (23% TBSA in methadone, 25% TBSA in non-methadone). There was no significant difference in reported preoperative pain intensity between the two groups, rating moderate to severe. Postoperative pain intensity remained the same, rating moderate to severe and controlled with fentanyl, oxycodone, morphine and non-opioid analgesics. While there was no difference in postoperative fentanyl, opioid and non-opioid analgesic consumptions between the two groups, morphine consumption was significantly lower in the methadone group compared to non-methadone group (2±2 mg vs 51±54 mg, respectively, p=0.02). There was no significant difference between average time from surgery to first physical therapy session and time to hospital discharge (about 21 days after surgery) between the two groups. Conclusions This evaluation shows a potential trend in reduction of inpatient postoperative opioid consumption with the conjunctive administration of methadone, although a bigger sample size is needed for further assessment.

Study Results

BackgroundEvidence suggests that over half of patients undergoing surgical procedures suffer from poorly controlled postoperative pain. In the context of an opioid epidemic, novel strategies for ameliorating postoperative pain and reducing opioid consumption are essential. Psychological interventions defined as strategies targeted towards reducing stress, anxiety, negative emotions and depression via education, therapy, behavioral modification and relaxation techniques are an emerging approach towards these endpoints.ObjectiveThis review explores the efficacy of psychological interventions for reducing postoperative pain and opioid use in the acute postoperative period.Evidence reviewAn extensive literature search was conducted in MEDLINE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Medline In-Process/ePubs, Embase, Ovid Emcare Nursing, and PsycINFO, Web of Science (Clarivate), PubMed-NOT-Medline (NLM), CINAHL and ERIC, and two trials registries, ClinicalTrials.Gov (NIH) and WHO ICTRP. Included studies were limited to those investigating adult human subjects, and those published in English.FindingsThree distinct forms of psychological interventions were identified: relaxation, psychoeducation and behavioral modification therapy. Study results showed a reduction in both postoperative opioid use and pain scores (n=5), reduction in postoperative opioid use (n=3), reduction in postoperative pain (n=5), no significant reduction in pain or opioid use (n=7), increase in postoperative opioid use (n=1) and an increase in postoperative pain (n=1).ConclusionSome preoperative psychological interventions can reduce pain scores and opioid consumption in the acute postoperative period; however, there is a clear need to strengthen the evidence for these interventions. The optimal technique, strategies, timing and interface requires further investigation.

Category: Other Introduction/Purpose: The tourniquet is commonly used in orthopedic surgeries on the upper and lower extremities to reduce blood loss, improve visualization, and expedite the surgical procedure. However, tourniquets have been associated with multiple local and systemic complications, including postoperative pain. Guidelines vary regarding ideal tourniquet pressure and duration, while the practice of fixed, high tourniquet pressures remains common. The relationship between tourniquet pressure, duration, and postoperative pain has been studied in various orthopaedic procedures, but these relationships remain unknown in foot and ankle surgery. The purpose of this study was to assess for correlation between excessive tourniquet pressure and duration and the increased incidence of tourniquet pain in foot and ankle surgery patients. Methods: Retrospective chart review was performed for 132 adult patients who underwent foot and ankle surgery with concomitant use of intraoperative tourniquet at a single institution between August and December of 2015. Patients with history of daily opioid use of 30 or more morphine oral equivalents for greater than 30 days, patients who underwent foot and ankle surgery without regional nerve block, patients deemed to have failed regional nerve block, and patients who underwent foot and ankle surgery without tourniquet use were excluded. Patient’s baseline systolic blood pressure, tourniquet pressure and duration, tourniquet deflation time, tourniquet reinflation pressure and duration, intraoperative blood pressure and heart rate changes, intra-operative opioid consumption, PACU pain scores, PACU opioid consumption, and PACU length of stay were collected. Statistical correlation between tourniquet pressure and duration and postoperative pain scores, pain location, narcotic use, and length of stay in PACU was assessed using linear regression in SPSS. Results: Average age of patients was 47.6 years (Range: 16 - 79). Tourniquet pressure was 280 mmHg in 90.6% of patients (Range: 250-300 mmHg). Only 3.8% percent of patients had tourniquet pressures 100-150 mmHg above systolic blood pressure. Mean tourniquet time was 106.2 ± 40.1 min. Tourniquet time showed significant positive correlation with morphine equivalents used in the perioperative period (N = 121; r = 0.406; p < 0.001). Long tourniquet times (= 90 minutes) were associated with greater intraoperative opioid use than short tourniquet times (= 90 minutes) (19 mg ± 22 mg vs. 5 mg ± 11.6 mg; p <0.001). Tourniquet duration and PACU length of stay had a positive association (R2 = 0.4). Conclusion: The majority of cases of foot and ankle surgery at our institution did not adhere to current tourniquet use guidelines, which recommend tourniquet pressure between 100 and 150 mmHg above patient’s systolic blood pressure. Prolonged tourniquet times at high pressures not based on limb occlusion pressure, as observed in our study, lead to increased pain and opioid use and prolonged time in PACU. Basing tourniquet pressures on limb occlusion pressures could likely improve the safety margin of tourniquets, however randomized studies need to be completed to confirm this.

Subsequent Injury

Category: Ankle Introduction/Purpose: Workers’ compensation (WC) has been associated with poor outcomes following a variety of injuries and surgeries. Previous studies have investigated surgical outcomes via satisfaction surveys, but rates of subsequent injury following surgery have not been specifically studied. The purpose of this study was to investigate the rates, locations and risk factors for subsequent injuries in WC patients and non-WC patients who underwent the same surgeries. Methods: With IRB approval, we identified the records of patients with a foot or ankle surgery performed by a single surgeon from 2009-2015. We included only surgeries with one of the most common current procedural terminology (CPT) codes from the WC population. A retrospective chart review was performed on all WC and non-WC patients with at least one of these CPT codes. A subsequent injury was defined as a new injury at a different anatomical location that occurred from 2 months to 2 years after the index surgery. Chi-square and two-tailed t-tests were used to compare WC and non-WC patient populations, and to determine factors associated with subsequent injuries. Results: Overall, the WC population had higher rates of subsequent injury than the non-WC population 23.21% versus 7.27%, p=.0011. Within the WC patient population, patients with subsequent injuries were older than patients without subsequent injuries 48.78±7.30 versus 41.58±12.40, p=.0137. In a blinded review of the charts and Iowa Courts Online, legal representation was found to be more common in WC patients with subsequent injuries than WC patients without subsequent injuries (76.92% versus 37.21%, p=.0240). In the non-WC population, there were more males in the group without subsequent injuries than in the group with subsequent injuries 42.48% versus 8.33%, p=.0287. There were no significant differences in locations of subsequent injury. Hip, knee and contralateral foot and ankle were common areas of subsequent injury in both groups. Conclusion: Overall, WC patients had higher rates of subsequent injury than non-WC patients. Within the WC group, legal representation further raised the risk of subsequent injury. Gender may mediate variable reporting of subsequent injuries in non-WC populations. While the reason for this increased risk of subsequent injury is not known, the differences are enough that they should be considered when counseling WC patients considering these surgeries. Additionally, if further study supported these findings, knowledge of the areas at risk for subsequent injury might lead to preventative strategies that could decrease the risk of subsequent injury.
