Opioid prescribing exceeds consumption following common surgical oncology procedures.

BACKGROUND AND OBJECTIVES: Surgical oncology patients are vulnerable to persistent opioid use. As such, we aim to compare opioid prescribing to opioid consumption for common surgical oncology procedures. METHODS: We prospectively identified patients undergoing common surgical oncology procedures at a single academic institution (August 2017-March 2018). Patients were contacted by telephone within 6 months of surgery and asked to report their opioid consumption and describe their discharge instructions and opioid handling practices. RESULTS: Of the 439 patients who were approached via telephone, 270 completed at least one survey portion. The median quantity of opioid prescribed was significantly larger than consumed following breast biopsy (5 vs. 2 tablets of 5 mg oxycodone, p < .001), lumpectomy (10 vs. 2 tablets of 5 mg oxycodone, p < .001), and mastectomy or wide local excision (20 tablets vs. 2 tablets of 5 mg oxycodone, p < .001). The majority of patients reported receiving education on taking opioids, but only 27% received instructions on proper disposal; 82% of prescriptions filled resulted in unused opioids, and only 11% of these patients safely disposed of them. CONCLUSIONS: This study demonstrates that opioid prescribing exceeds consumption following common surgical oncology procedures, indicating the potential for reductions in prescribing.

The Impact of Education and Prescribing Guidelines on Opioid Prescribing for Breast and Melanoma Procedures.

BACKGROUND: Excessive opioid prescribing is common in surgical oncology, with 72% of prescribed opioids going unused after curative-intent surgery. In this study, we sought to reduce opioid prescribing after breast and melanoma procedures by designing and implementing an intervention focused on education and prescribing guidelines, and then evaluating the impact of this intervention. METHODS: In this single-institution study, we designed and implemented an intervention targeting key factors identified in qualitative interviews. This included mandatory education for prescribers, evidence-based prescribing guidelines, and standardized patient instructions. After the intervention, interrupted time-series analysis was used to compare the mean quantity of opioid prescribed before and after the intervention (July 2016-September 2017). We also evaluated the frequency of opioid prescription refills. RESULTS: During the study, 847 patients underwent breast or melanoma procedures and received an opioid prescription. For mastectomy or wide local excision for melanoma, the mean quantity of opioid prescribed immediately decreased by 37% after the intervention (p = 0.03), equivalent to 13 tablets of oxycodone 5 mg. For lumpectomy or breast biopsy, the mean quantity of opioid prescribed decreased by 42%, or 12 tablets of oxycodone 5 mg (p = 0.07). Furthermore, opioid prescription refills did not significantly change for mastectomy/wide local excision (13% vs. 14%, p = 0.8), or lumpectomy/breast biopsy (4% vs. 5%, p = 0.7). CONCLUSION: Education and prescribing guidelines reduced opioid prescribing for breast and melanoma procedures without increasing the need for refills. This suggests further reductions in opioid prescribing may be possible, and provides rationale for implementing similar interventions for other procedures and practice settings.

Transitions of Care for Postoperative Opioid Prescribing in Previously Opioid-Naïve Patients in the USA: a Retrospective Review.

BACKGROUND: New persistent opioid use is a common postoperative complication, with 6% of previously opioid-naïve patients continuing to fill opioid prescriptions 3-6 months after surgery. Despite these risks, it is unknown which specialties prescribe opioids to these vulnerable patients. OBJECTIVE: To identify specialties prescribing opioids to surgical patients who develop new persistent opioid use. DESIGN, SETTING, AND PARTICIPANTS: Using a national dataset of insurance claims, we identified opioid-naïve patients aged 18-64 years undergoing surgical procedures (2008-2014) who continued filling opioid prescriptions 3 to 6 months after surgery. We then examined opioid prescriptions claims during the 12 months after surgery, and identified prescribing physician specialty using National Provider Identifier codes. MAIN MEASURES: Percentage of opioid prescriptions provided by each specialty evaluated at 90-day intervals during the 12 months after surgery. KEY RESULTS: We identified 5276 opioid-naïve patients who developed new persistent opioid use. During the first 3 months after surgery, surgeons accounted for 69% of opioid prescriptions, primary care physicians accounted for 13%, Emergency Medicine accounted for 2%, Physical Medicine & Rehabilitation (PM&R)/Pain Medicine accounted for 1%, and all other specialties accounted for 15%. In contrast, 9 to 12 months after surgery, surgeons accounted for only 11% of opioid prescriptions, primary care physicians accounted for 53%, Emergency Medicine accounted for 5%, PM&R/Pain Medicine accounted for 6%, and all other specialties provided 25%. CONCLUSIONS: Among surgical patients who developed new persistent opioid use, surgeons provide the majority of opioid prescriptions during the first 3 months after surgery. By 9 to 12 months after surgery, however, the majority of opioid prescriptions were provided by primary care physicians. Enhanced care coordination between surgeons and primary care physicians could allow earlier identification of patients at risk for new persistent opioid use to prevent misuse and dependence.

Association of Mechanical Axis With Osteochondritis Dissecans of the Femoral Condyle.

BACKGROUND: Osteochondritis dissecans (OCD) is a condition characterized by abnormal subchondral bone with disturbance of overlying articular cartilage. The role of weightbearing alignment in the pathophysiology of OCD lesion development is not fully understood. HYPOTHESIS: Lower extremity mechanical axis would be concordant with femoral condylar OCD lesion location. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Cases were identified from a single, large academic institutional database using International Classification of Diseases, Ninth Revision and Tenth Revision and Current Procedural Terminology codes associated with OCD. Patients were included if they had a magnetic resonance imaging scan demonstrating the OCD lesion and lower extremity alignment radiographs. OCD lesion location was identified using Cahill and Berg zones. The primary outcome was the association of OCD lesion location with weightbearing mechanical axis. Secondary outcomes included the association of mechanical axis with skeletal maturity, OCD lesion stability, and treatment. For unilateral OCD lesions, mechanical axis was compared between affected and unaffected lower extremities. RESULTS: A total of 86 patients (95 knees) with an OCD lesion of the femoral condyle were identified. The population was 74% male, and the mean age was 21 years. In total, 65% of knees had closed physes, 82% of lesions were unstable, and 85% underwent a surgical procedure. Mechanical axis was located in the same zone as the OCD lesion in 48% of cases and within the same compartment in 56% of cases. Spearman correlation coefficient demonstrated a moderate positive correlation (rs = 0.59). No significant differences were found in the association of mechanical axis and OCD lesion location in subgroup analysis of medial versus lateral femoral condylar OCD lesions, skeletal maturity, stability of the lesion, or treatment group. For patients with varus alignment and medial femoral condylar OCD lesions, the mean lateral distal femoral angle was 89.9°, and medial proximal tibial angle was 85.4°; for valgus alignment and lateral femoral condylar lesions, the lateral distal femoral angle was 84.8°, and medial proximal tibial angle was 88.8°. Patients with unilateral medial femoral condylar OCD lesions were more likely to have varus alignment of the affected extremity compared with the contralateral extremity (59% vs 36%; P = .01). CONCLUSION: This study demonstrated a relationship between lower extremity mechanical weightbearing axis and femoral condylar OCD location. Patients with unilateral medial femoral condylar OCD lesions frequently had asymmetric varus alignment in the affected extremity.

Return to Sports Rates in Pediatric Patients After Bilateral Versus Unilateral Medial Patellofemoral Ligament Reconstruction.

BACKGROUND: Patellofemoral instability commonly occurs during sports activities. The return to sports (RTS) rate for pediatric patients after bilateral medial patellofemoral ligament reconstruction (MPFLR) is unknown. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate RTS outcomes for pediatric patients undergoing bilateral MPFLR. It was hypothesized that (1) fewer pediatric patients would RTS after bilateral MPFLR compared with unilateral MPFLR and that (2) for those in the bilateral cohort who were able to RTS, fewer patients would attain the same level of play as or higher level than the preinjury level. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: We prospectively collected RTS data on retrospectively identified matched cohorts of patients aged ≤18 years who underwent unilateral and bilateral MPFLR. We matched each participant with bilateral MPFLR at a 1 to 2 ratio with a participant with unilateral MPFLR by concomitant procedure, age, and sex. Postoperative complications and preoperative imaging measurements were collected from medical records. Patient-reported outcomes were obtained using a current Single Assessment Numeric Evaluation score collected at the time of primary outcome data. RESULTS: We matched 16 participants (mean age, 14 years) who underwent bilateral MPFLR to 32 participants (mean age, 14.3 years) in a corresponding unilateral MPFLR cohort. We found a significant decrease in RTS rates for pediatric patients after bilateral MPFLR when compared with unilateral MPFLR (69% vs 94%; P = .03). Among those who returned to sports, there was no difference in the level of play achieved. For participants who did not RTS or returned at a lower level of play after bilateral MPFLR, 57% cited fear of reinjury as the primary reason. There were no differences in postoperative complications or current Single Assessment Numeric Evaluation scores between cohorts. The bilateral cohort had a significantly higher Caton-Deschamps index compared with the unilateral cohort, although the absolute difference was small (1.3 vs 1.2; P = .005). CONCLUSION: We found that pediatric patients have a lower RTS rate after bilateral MPFLR when compared with a matched unilateral MPFLR cohort. No differences in the level of play were achieved among those who returned to sports. Fear of reinjury was a commonly cited reason for not returning to sports.

The rate of disuse osteopenia in admitted, non-weight-bearing patients.

Disuse osteopenia is a well-recognized consequence of prolonged physical inactivity, but its rate after orthopaedic injuries necessitating non-weight-bearing is not well studied. The purpose of this study was to estimate the rate of disuse osteopenia at the lumbar spine and proximal femur in patients with lower extremity trauma admitted to the hospital. We performed a retrospective chart review of patients with lower extremity trauma with a period of strict non-weight-bearing between completion of two computed tomography (CT) scans. The radiodensity of the proximal femur or lumbar vertebrae was measured from the earliest and latest available CT scans within the non-weight-bearing timeframe. The change in estimated bone mineral density (eBMD) was calculated as a proxy for disuse osteopenia. A total of 189,111 patients were screened, with 17 patients in the proximal femur group and 15 patients in the lumbar spine group meeting inclusion and exclusion criteria. The average rate of change in eBMD of the proximal femur was a decrease of 7.54 HU/day, 95% confidence interval (CI) [3.65, 11.43]. The average rate of change in eBMD of the lumbar spine was an increase of 1.45 HU/day, 95% CI [-3.15, 6.06]. In admitted, non-weight-bearing orthopaedic trauma patients, our novel study suggests that the proximal femur experiences disuse osteopenia during periods of non-weight-bearing, although this finding was not observed at the lumbar spine. The clinical significance of this data underscores the important consideration of disuse osteopenia by all physicians when caring for patients that may require non-weight-bearing restrictions.

Postoperative opioid prescribing is not my job: A qualitative analysis of care transitions.

BACKGROUND: Persistent opioid use is common after surgical procedures, and postoperative opioid prescribing often transitions from surgeons to primary care physicians in the months after surgery. It is unknown how surgeons currently transition these patients or the preferred approach to successful coordination of care. This qualitative study aimed to describe transitions of care for postoperative opioid prescribing and identify barriers and facilitators of ideal transitions for potential intervention targets. METHODS: We conducted a qualitative study of surgeons and primary care physicians at a large academic healthcare system using a semi-structured interview guide. Transcripts were independently coded using the Theoretical Domains Framework to identify underlying determinants of physician behaviors. We mapped dominant themes to the Behavior Change Wheel to propose potential interventions targeting these behaiors. RESULTS: Physicians were interviewed between July 2017 and December 2017 beyond thematic saturation (n = 20). Surgeons report passive transitions to primary care physicians after ruling out surgical complications, and these patients often bounce back to the surgeon when primary care physicians are uncertain of the cause of ongoing pain. Ideal practices were identified as setting preoperative expectations and engaging in active transition for postoperative opioid prescribing. We identified 3 behavioral targets for multidisciplinary intervention: knowledge (guidelines for coordination of care), barriers (utilizing support staff for active transition), and professional role (incentive for multidisciplinary collaboration). CONCLUSION: This qualitative study identifies potential interventions aimed at changing physician behaviors regarding transitions of care for postoperative opioid prescribing. Implementation of these interventions could improve coordination of care for patients with persistent postoperative opioid use.
