Study of variations in inpatient opioid consumption after total shoulder arthroplasty: influence of patient- and surgeon-related factors

Kolade, Oluwadamilola O; Ghosh, Niloy; Fernandez, Laviel; Friedlander, Scott; Zuckerman, Joseph D; Bosco, Joseph A; Virk, Mandeep S
BACKGROUND:The aims of this study were to examine variances in inpatient opioid consumption after total shoulder arthroplasty (TSA) and to determine factors influencing inpatient opioid utilization. METHODS:The sample included patients undergoing elective TSA at a tertiary-level institution between January 2016 and April 2018. Opioid consumption during the inpatient stay was converted into morphine milligram equivalents (MMEs), accounting for dosage and route of administration. The MMEs were calculated per patient encounter and used to calculate mean opioid consumption. Bivariate linear regression analysis was performed to assess the impact of patient-related factors and surgery-related factors on inpatient opioid consumption. RESULTS:Altogether 20 surgeons performed 622 TSAs. The average opioid dose per encounter was 47.4 ± 65.7 MME/d. MMEs prescribed varied significantly among surgeon providers (P < .01). Pre-existing psychiatric disorders (P = .00012), preoperative opioid use (P = .0013), highest quartile of median household income (P = .048), current-smoker status (P < .001), age < 60 years (P < .01), and general anesthesia (vs. regional anesthesia, P = .005) were associated with significant inpatient opioid consumption after TSA. Sex, race, American Society of Anesthesiologists status, replacement type (anatomic TSA vs. reverse TSA), and prior shoulder surgery did not show any significant differences. CONCLUSION/CONCLUSIONS:There is considerable variation in inpatient opioid consumption after TSA at the same institution. Knowledge of modifiable and nonmodifiable risk factors that increase inpatient opioid consumption will help to optimize multimodal analgesia protocols for TSA.

Access to Elective Orthopaedic Surgery After the Affordable Care Act Medicaid Expansion: The New York State Experience

Williamson, Tyler R; Paoli, Albit R; Hutzler, Lorraine; Zuckerman, Joseph; Bosco, Joseph
BACKGROUND:As part of the Patient Protection and Affordable Care Act, states were given the option of expanding Medicaid coverage to include adults younger than age 65 years with income at or below 138% of the federal poverty level. Although this expansion was intended to provide health care coverage to an estimated 20 million Americans, several studies have shown increased coverage does not equate to increased access to care by specialty providers. METHODS:We queried the New York Statewide Planning and Research Cooperative System database and identified all patients who underwent the 10 most common elective orthopaedic surgeries from January 1, 2012, through March 31, 2016. Medicaid monthly enrollment for the 4-year study period was obtained from NY Department of Health Medicaid Managed Care Enrollment Reports. RESULTS:Our query identified 700,159 patients who underwent the investigated orthopaedic surgeries. Of these, 60,786 were Medicaid recipients. During the 4-year study period, Medicaid enrollment and the number of procedures reimbursed by Medicaid increased significantly (P < 0.001 for both). CONCLUSIONS:Affordable Care Act-supported Medicaid expansion was associated with an increase in Medicaid enrollment and a concomitant increase in the utilization of orthopaedic surgery by Medicaid beneficiaries in New York State.

Does femoral morphology and stem alignment influence outcomes of cementless total hip arthroplasty with proximally coated double-tapered titanium stems?

Narayanan, Rajkishen; Elbuluk, Ameer M; Chen, Kevin K; Eftekhary, Nima; Zuckerman, Joseph D; Deshmukh, Ajit J
INTRODUCTION/UNASSIGNED:Stem subsidence and thigh pain can cause significant patient dissatisfaction after cementless THA. The purpose of this study was to examine the effect of proximal-femoral morphology and stem alignment on clinical outcomes using a double-tapered, cementless titanium femoral component. METHODS/UNASSIGNED:We retrospectively reviewed 281 consecutive, primary THAs from 2012 to 2014 with a mean follow-up of 4 years. Preoperative radiographs were used to assess femoral neck shaft angle (FNS), canal flare index (CFI), Dorr classification, and greater trochanter (GT) overhang. Postoperative radiographs were used to determine stem alignment and 6-week follow-up radiographs were used to determine subsidence. Clinical outcomes included thigh pain, leg-length discrepancy (LLD), patient-reported outcome measures (PROMs) and revision surgeries. RESULTS/UNASSIGNED: 0.03) and FNS was inversely associated with postoperative HOOS scores. CONCLUSIONS/UNASSIGNED:Subsidence and proximal-femoral morphology are potential sources of postoperative morbidity in certain cementless THA patients. In accordance with prior studies, CFI was identified as a potential risk factor for intraoperative calcar fractures. More research into preoperative femoral morphologies, such as GT overhang and FNS, is warranted as these may contribute to unsatisfactory results related to cementless THA.

Assessment of intraoperative joint loads and mobility in reverse total shoulder arthroplasty through a humeral trial sensor

Verstraete, Matthias A.; Conditt, Michael A.; Parsons, Ira M.; Greene, Alexander T.; Roche, Christopher P.; Decerce, Joseph; Jones, Richard B.; Youderian, Ari R.; Wright, Thomas W.; Zuckerman, Joseph D.
Hypothesis: The use of intraoperative glenohumeral load sensors has the potential to facilitate an objective, quantitative assessment of the soft tissue tension during reverse total shoulder arthroplasty. Material and Methods: A reverse total shoulder arthroplasty was performed on eight fresh frozen cadaveric shoulders, creating three different tightness conditions for each shoulder by using various shim thicknesses attached to an instrumented, load-sensing humeral trial component. The glenohumeral loads were recorded during four dynamic maneuvers, consisting of maximum internal/external rotation at 0-, 45- and 90-degree abduction and forward elevation. The joint kinematics were synchronously recorded using an optical tracking system. Results: For normal tightness conditions, 98.3% of the observed loads were below 40 lbf. These loads varied through the range of motion with an increase in glenohumeral loads generally observed towards the limits of the range of motion. With increasing shoulder tightness, the range of motion of the joint was not significantly affected, though the average and maximum glenohumeral load significantly increased (p < 0.01 for all). Conclusion: In a cadaveric setting, higher glenohumeral loads were observed at higher tightness conditions, demonstrating the potential of a load-sensing humeral trial component to quantify intraoperative joint load with reverse total shoulder arthroplasty. The glenohumeral loads are increasing towards the limits of the range of motion, indicating the importance of performing dynamic assessment of stability at the extents of the range of motion during implant trialing.

Acute versus delayed reverse total shoulder arthroplasty for proximal humerus fractures in the elderly: Mid-term outcomes

Kuhlmann, Noah A.; Taylor, Kevin A.; Roche, Christopher P.; Franovic, Sreten; Chen, Chaoyang; Carofino, Bradley C.; Flurin, Pierre Henri; Wright, Thomas W.; Schoch, Bradley S.; Zuckerman, Joseph D.; Muh, Stephanie J.
Background: Treatment of proximal humerus fractures (PHFs) via reverse total shoulder arthroplasty (RTSA) has shown early promise when compared to historical treatment modalities. Ideal surgical timing remains unclear. The purpose of this study was to compare the outcomes of early versus delayed RTSA for PHF. We hypothesized that acute RTSA would display superior outcomes compared to those receiving delayed surgical intervention. Methods: This multicenter study retrospectively analyzed 142 patients who underwent RTSA for fracture. Patients treated within 4 weeks of injury were placed in the acute group (n = 102), and patients treated longer than 4 weeks after injury were placed in the chronic group (n = 38). A comprehensive panel of patient reported outcome measures, VAS pain scores, range of motion, and patient satisfaction were evaluated. Results: The acute group had significantly better final follow-up SPADI scores (20.8 ± 23.9 vs. 30.7 ± 31.7) (p<0.05). No further differences were detected in other postoperative range of motion measurements, subjective outcomes, or VAS scores. Conclusions: Our results suggest that patients treated acutely display similar mid-term outcomes to those who receive delayed treatment. With this in mind, surgeons may first give consideration to a period of nonoperative treatment. Level of evidence: Level II.

Personality Predictors of Communication Skills Among Orthopedic Surgery Residents

Holmes, Kathryn S; Zuckerman, Joseph D; Maculatis, Martine C; Friedman, Alan M; Lawrence, Eleanor; Phillips, Donna P
INTRODUCTION/BACKGROUND:This study examined the relationship between personality traits and interpersonal communication skills among first-year orthopedic surgery residents. METHOD/METHODS:This study performed a retrospective analysis on the data collected in the 2 phases among the 6 cohorts of first-year orthopedic surgery residents (n = 73) during a 6-year period at an urban academic medical hospital. Resident personality was assessed through self-report prior to entry into the program and included a total of 7 personality traits. These traits were broken down into 2 categories, day to day, or usual, tendencies, which measured personality traits when no stress was present and stress tendencies, which measured personality traits when stressed or fatigued. The "day to day" tendencies measured were Emotional Stability, Agreeableness, Conscientiousness and Openness) and "stress" tendencies measured were Excitable, Skeptical and Imaginative. Communication skills were measured across 4 specific dimensions of patient communication (Engage, Empathy, Educate, Enlist) in an Objective Structured Clinical Examination (OSCE). RESULTS:Multiple regression analyses showed that the personality traits identified as "stress" tendencies predicted performance on 2 of the 4 communication skills dimensions measured by the OSCE and accounted for up to 34.8% of the total variance in the ratings of empathic communication and up to 67.2% of the total variance in education-related communication. CONCLUSIONS:Our research identifies specific personality traits that affect resident communication skills related to patient education and empathy in simulated encounters. Three stress-related personality traits (Excitable, Skeptical, Imaginative) had a strong negative influence on communication skills, while day to day personality traits (Emotional Stability, Agreeableness, Conscientiousness) positively influenced communication skills.

Managing Glenoid Deformity in Shoulder Arthroplasty: Role of New Technology (Computer-Assisted Navigation and Patient-Specific Instrumentation)

Virk, Mandeep S; Steinmann, Scott P; Romeo, Anthony A; Zuckerman, Joseph D
The glenoid is considered a weak link in total shoulder arthroplasty because failure on the glenoid side is one of the most common reasons for revision of total shoulder arthroplasty. Glenoid wear is commonly seen in glenohumeral arthritis and compromises glenoid bone stock and also alters the native version and inclination of the glenoid. It is critical to recognize glenoid wear and correct it intraoperatively to avoid component malposition, which can negatively affect the survivorship of the glenoid implant. The end point of correction for the glenoid wear in shoulder arthroplasty is controversial, but anatomic glenoid component positioning is likely to improve long-term survivorship of the total shoulder arthroplasty. Preoperative three-dimensional (3-D) computer planning software, based on CT, is commercially available. It allows the surgeon to plan implant type (anatomic versus reverse), size, and position on the glenoid, and also allows for templating deformity correction using bone graft and/or augments. Guidance technology in the form of computer-assisted surgery (CAS) and patient-specific instrumentation (PSI) allows the surgeon to execute the preoperative plan during surgery with a greater degree of accuracy and precision and has shown superiority to standard instrumentation. However, the proposed benefits of this technology including improved glenoid survivorship, reduced revision arthroplasty rate and cost-effectiveness have not yet been demonstrated clinically. In this review, we present the current evidence regarding PSI and CAS in managing glenoid deformity in total shoulder arthroplasty.
