A Shadow of Doubt: Is There Implicit Bias Among Orthopaedic Surgery Faculty and Residents Regarding Race and Gender?

BACKGROUND: Orthopaedic surgery continues to be one of the least diverse medical specialties. Recently, increasing emphasis has been placed on improving diversity in the medical field, which includes the need to better understand existing biases. Despite this, only about 6% of orthopaedic surgeons are women and 0.3% are Black. Addressing diversity, in part, requires a better understanding of existing biases. Most universities and residency programs have statements and policies against discrimination that seek to eliminate explicit biases. However, unconscious biases might negatively impact the selection, training, and career advancement of women and minorities who are underrepresented in orthopaedic surgery. Although this is difficult to measure, the Implicit Association Test (IAT) by Project Implicit might be useful to identify and measure levels of unconscious bias among orthopaedic surgeons, providing opportunities for additional interventions to improve diversity in this field. QUESTIONS/PURPOSES: (1) Do orthopaedic surgeons demonstrate implicit biases related to race and gender roles? (2) Are certain demographic characteristics (age, gender, race or ethnicity, or geographic location) or program characteristics (geographic location or size of program) associated with the presence of implicit biases? (3) Do the implicit biases of orthopaedic surgeons differ from those of other healthcare providers or the general population? METHODS: A cross-sectional study of implicit bias among orthopaedic surgeons was performed using the IAT from Project Implicit. The IAT is a computerized test that measures the time required to associate words or pictures with attributes, with faster or slower response times suggesting the ease or difficulty of associating the items. Although concerns have been raised recently about the validity and utility of the IAT, we believed it was the right study instrument to help identify the slight hesitation that can imply differences between inclusion and exclusion of a person. We used two IATs, one for Black and White race and one for gender, career, and family roles. We invited a consortium of researchers from United States and Canadian orthopaedic residency programs. Researchers at 34 programs agreed to distribute the invitation via email to their faculty, residents, and fellows for a total of 1484 invitees. Twenty-eight percent (419) of orthopaedic surgeons and trainees completed the survey. The respondents were 45% (186) residents, 55% (228) faculty, and one fellow. To evaluate response biases, the respondent population was compared with that of the American Academy of Orthopaedic Surgeons census. Responses were reported as D-scores based on response times for associations. D-scores were categorized as showing strong (≥ 0.65), moderate (≥ 0.35 to < 0.65), or slight (≥ 0.15 to < 0.35) associations. For a frame of reference, orthopaedic surgeons' mean IAT scores were compared with historical scores of other self-identified healthcare providers and that of the general population. Mean D-scores were analyzed with the Kruskal-Wallis test to determine whether demographic characteristics were associated with differences in D-scores. Bonferroni correction was applied, and p values less than 0.0056 were considered statistically significant. RESULTS: Overall, the mean IAT D-scores of orthopaedic surgeons indicated a slight preference for White people (0.29 ± 0.4) and a slight association of men with career (0.24 ± 0.3), with a normal distribution. Hence, most respondents' scores indicated slight preferences, but strong preferences for White race were noted in 27% (112 of 419) of respondents. There was a strong association of women with family and home and an association of men with work or career in 14% (60 of 419). These preferences generally did not correlate with the demographic, geographic, and program variables that were analyzed, except for a stronger association of women with family and home among women respondents. There were no differences in race IAT D-scores between orthopaedic surgeons and other healthcare providers and the general population. Gender-career IAT D-scores associating women with family and home were slightly lower among orthopaedic surgeons (0.24 ± 0.3) than among the general population (0.32 ± 0.4; p < 0.001) and other healthcare professionals (0.34 ± 0.4; p < 0.001). All of these values are in the slight preference range. CONCLUSION: Orthopaedic surgeons demonstrated slight preferences for White people, and there was a tendency to associate women with career and family on IATs, regardless of demographic and program characteristics, similar to others in healthcare and the general population. Given the similarity of scores with those in other, more diverse areas of medicine, unconscious biases alone do not explain the relative lack of diversity in orthopaedic surgery. CLINICAL RELEVANCE: Implicit biases only explain a small portion of the lack of progress in improving diversity, equity, inclusion, and belonging in our workforce and resolving healthcare disparities. Other causes including explicit biases, an unwelcoming culture, and perceptions of our specialty should be examined. Remedies including engagement of students and mentorship throughout training and early career should be sought.

Eccentric Hamstring Strength Imbalance among Football and Soccer Athletes.

OBJECTIVES: Hamstring strain injuries (HSI) are common among football and soccer athletes. Eccentric strength imbalance is considered a contributing factor for HSI. There is, however, a paucity of data on hamstring imbalances of soccer and American football athletes as they age and advance in skill level. High school athletes will display greater interlimb discrepancies compared with collegiate and professional athletes. In addition, soccer athletes will exhibit greater hamstring asymmetry than American football athletes. METHODS: Hamstring testing was performed on soccer and American football athletes using the NordBord Hamstring Testing System (Vald Performance, Albion, Australia). Age, sex, weight, sport specialization, and sport level were recorded. Maximum hamstring forces (N), torque (N · m), and work (N · s) were measured. Hamstring imbalance (%) was calculated by dividing the absolute value of the difference in leg forces divided by their sum. One-way analysis of variance and independent sample t tests compared measurements between athlete groups. RESULTS: A total of 631 athletes completed measurements, including 88 high school male soccer, 25 college male soccer, 23 professional male soccer, 83 high school female soccer, 28 college female soccer, 288 high school football, and 96 college football athletes. High school soccer players displayed significantly greater imbalances for torque (P = 0.03) and work (P < 0.01) than football athletes. Imbalances for maximum force (P = 0.035), torque (P = 0.018), and work (P = 0.033) were significantly higher for male soccer athletes in high school compared with college- and professional-level athletes. Female high school soccer players had significantly higher imbalance in torque (P = 0.045) and work (P = 0.001) compared with female collegiate soccer players. Football athletes did not experience significant changes in force imbalances between skill levels. CONCLUSIONS: High school soccer athletes exhibit greater hamstring imbalances than football athletes. Higher levels of play in soccer, for both male and female athletes, correlate with less hamstring asymmetry.

Biofilm Growth on Orthopaedic Cerclage Materials: Nonmetallic Polymers Are Less Resistant to Methicillin-Resistant Staphylococcus Aureus Bacterial Adhesion.

BACKGROUND: Data on bacterial adhesion to cerclage cables are sparse. We aimed to compare 5 cerclage products for methicillin-resistant Staphylococcus aureus (MRSA) adhesion to determine the claim: Are nonmetallic polymer cables more resistant to bacterial adhesion than common metallic wires and cables? METHODS: The following 5 cerclage products were compared: (1) monofilament stainless steel (SS) wires; (2) multifilament SS cables; (3) multifilament cobalt chrome cables; (4) multifilament Vitallium alloy (cobalt-chrome-molybdenum [Co-Cr-Mo]) cables; and (5) multifilament nonmetallic polymer cables. Each was cut into 2 cm lengths and placed into 12-well plates. Of the wells, 5 were wire or cables in trypticase soy broth with MRSA, with the remaining wells being appropriate controls incubated for 24 hours at 37° C and 5% CO2 with shaking. Wires and cables were prepared and randomly imaged via scanning electron microscopy, with bacterial counts performed on 3 images of 3 different wires or cables per study group. The scanning electron microscopy technician and counting investigator were blinded. Additionally, SS wire and polymer cables were analyzed by microcalorimetry for metabolic activity and bacterial load. RESULTS: Bacterial attachment differed significantly between study groups in the middle section (P = .0003). Post hoc comparison showed no difference between groups individually (all P > .05) apart from polymer cables (median 551 bacteria) having significantly increased attached bacteria compared to the Vitallium alloy cable (157, P = .0004), SS cable (101, P = .0004), and SS wire (211, P = .0004). There was no difference between polymer and cobalt chrome cables (133, P = .056). Microcalorimetry supported these results, as polymer cables had a shorter time to max heat flow (6.2 versus 7.5 hours, P = .006), increased max heat flow (117 versus 64 uW, P = .045), and increased colony-forming units, indicating an increased bacterial load compared to SS wires. CONCLUSIONS: This in vitro study demonstrated that polymer cables have increased MRSA adhesion compared to common metallic wires and cables. Future studies are necessary to confirm the translation of increased bacterial adherence on polymer cables to increased rates of orthopaedic infections.

Impact of the Percentage of Overlapping Surgery on Patient Outcomes: A Retrospective Cohort Study of 87,000 Surgical Cases.

OBJECTIVES: The primary objective of this study was to analyze the relationship of percentage of surgical overlap with patient outcomes to determine if a detrimental level of overlap exists. BACKGROUND: Overlapping surgery is defined as 1 attending physician supervising 2 or more operative cases simultaneously, without the critical portions of the cases occurring concurrently. To date, no study has examined the relationship of percent overlap, or the percentage of 1 case that is spent overlapping with another, to outcomes, efficiency, safety, and complications. METHODS: This study is a retrospective cohort study conducted at a large tertiary referral center. The primary outcomes of interest included operative duration, in-hospital mortality, 30-day readmission, and patient safety indicators (PSIs). The Cochran-Armitage test for trend was used to evaluate the outcomes of interest. P values of ≤0.05 were considered statistically significant. RESULTS: A total of 87,426 cases were included in this study. There were 62,332 cases without overlap (Group 0), 10,514 cases with 1% to 25% overlap (Group 1), 5303 cases with 26% to 50% overlap (Group 2), 4296 cases with 51% to 75% overlap (Group 3), and 4981 cases with >75% overlap (Group 4). In-hospital mortality decreased as overlap increased ( Ptrend <0.0001). Operative time increased with increasing overlap ( Ptrend <0.0001) while readmission rates showed no statistical significance between groups ( Ptrend =0.5078). Rates of PSIs were lower for Groups 1, 2, and 3 (1.69%, 2.01%, and 2.08%) when compared to Group 0 (2.24%). Group 4 had the highest rate of PSIs at 2.35% ( P =0.0086). CONCLUSION: Overlapping surgery was shown to have reduced in-hospital mortality and similar PSI and readmission rates when compared to nonoverlapping cases. Operative time was shown to increase in overlapping surgeries when compared to nonoverlapping surgeries. The results from this study indicate that the percentage of surgical overlap does not detrimentally affect most patient outcomes, especially with overlap of <75%.

Elective Hand Surgery Is Delayed among Private Insurance Holders.

OBJECTIVES: Patients with private healthcare plans often defer nonemergent or elective procedures toward the end of the year once they have met their deductible. No previous studies have evaluated how insurance status and hospital setting may affect surgical timing for upper extremity procedures. Our study aimed to evaluate the influence of insurance and hospital setting on end-of-the-year surgical cases for elective carpometacarpal (CMC) arthroplasty, carpal tunnel, cubital tunnel, and trigger finger release, and nonelective distal radius fixation. METHODS: Insurance provider and surgical dates were gathered from two institutions' electronic medical records (one university, one physician-owned hospital) for those undergoing CMC arthroplasty, carpal tunnel release, cubital tunnel release, trigger finger release, and distal radius fixation from January 2010 to December 2019. Dates were converted into corresponding fiscal quarters (Q1-Q4). Using the Poisson exact test, comparisons were made between the case volume rate of Q1-Q3 and Q4 for private insurance and then for public insurance. RESULTS: Overall, case counts were greater in Q4 than the rest of the year at both institutions. There was a significantly greater proportion of privately insured patients undergoing hand and upper extremity surgery at the physician-owned hospital than the university center (physician owned: 69.7%, university: 50.3%; P < 0.001). Privately insured patients underwent CMC arthroplasty and carpal tunnel release at a significantly greater rate in Q4 compared with Q1-Q3 for both institutions. Publicly insured patients did not experience an increase in carpal tunnel releases during the same period at both institutions. CONCLUSIONS: Privately insured patients underwent elective CMC arthroplasty and carpal tunnel release procedures in Q4 at a significantly greater rate than publicly insured patients. This finding suggests private insurance status, and potentially deductibles, influence surgical decision making and timing. Further work is needed to evaluate the impact of deductibles on surgical planning and the financial and medical impact of delaying elective surgeries.

COVID-19 Impact on Orthopedic Surgeons: Elective Procedures, Telehealth, and Income.

OBJECTIVES: The purpose of this study was to investigate the response in orthopedic surgery to the coronavirus disease 2019 (COVID-19) pandemic across the United States by surveying surgeons about their care setting, timing of restrictions on elective surgery, use of telehealth, and estimated economic impact. METHODS: A survey was distributed via REDCap through state orthopedic organizations between April and July 2020. The 22-question digital survey collected information regarding restrictions on elective procedures, location of care, utilization of telehealth, and estimated reductions in annual income. RESULTS: In this study, 192 participants responded to the survey (average age 49.9 ± 11.0 years, 92.7% male). Responses primarily originated from Alabama (30.2%), Georgia (30.2%), and Missouri (16.1%). The remainder of the responses were grouped into the category "other." Respondents did not vary significantly by state in operative setting or income type (salary, work relative value units, or collections). Most of the participants documented elective procedure restrictions in hospital and ambulatory settings. The highest frequency of closures occurred between March 18 and 20 (47% in hospital, 51% in ambulatory). Of the participants, financial loss estimates varied across states (P = 0.005), with 50% of physicians claiming >50% losses of income in Alabama (24% Georgia, 10% Missouri, 31% other). Regarding telehealth, practices set up for these services before 2020 varied across states. None of the orthopedic practices in Alabama had telehealth before the COVID-19 pandemic (Missouri 25%, Georgia 9%, other 8%, P = 0.06); however, respondents generally were split when considering the anticipation of implementing telehealth into routine practice. CONCLUSIONS: Most practices did implement restrictions for elective clinic visits and procedures early during the pandemic. COVID-19 ultimately will result in a large revenue loss for elective orthopedic practices. Services such as telehealth may help offset these losses and help deliver orthopedic care to patients remotely.

Is outpatient shoulder arthroplasty safe? A systematic review and meta-analysis.

BACKGROUND: Amid rising health care costs and recent advances in surgical and anesthetic protocols, the rate of outpatient joint arthroplasty has risen steadily in recent years. Although the safety of outpatient total knee arthroplasty and total hip arthroplasty has been well established, outpatient shoulder arthroplasty is still in its infancy. The purpose of this study was to synthesize the current literature and provide further data regarding the outcomes and safety of outpatient shoulder arthroplasty. METHODS: A systematic review was conducted following the standard PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included were studies that evaluated the outcomes of patients undergoing outpatient total shoulder arthroplasty (TSA) or reverse TSA. Meta-analysis was conducted using Mantel-Haenszel statistics to generate odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) comparing outpatient and inpatient shoulder arthroplasty. RESULTS: Twelve studies were included, with a total of 194,513 patients, of whom 7162 were outpatients. Of the studies, 8 were level III and 4 were level IV. The average age of the outpatients was 66.6 years, and the average age of the inpatients was 70.1 years. The overall OR for complications was significantly lower in outpatients (OR, 0.40; 95% CI, 0.35-0.45) than in inpatients. There was no significant difference in rates of 90-day readmission (OR, 0.88; 95% CI, 0.75-1.03), revision (OR, 0.96; 95% CI, 0.65-1.41), and infection (OR, 0.93; 95% CI, 0.64-1.35) when comparing outpatients with inpatients. CONCLUSION: Outpatient TSA, in an appropriately selected patient population, is safe and results in comparable patient outcomes to those of inpatient shoulder arthroplasty. Given the expected increase in the number of patients requiring TSA, surgeons, hospital administrators, and insurance carriers should strongly consider the merits of a cost- and care-efficient approach to total shoulder replacement.

Quality Improvement Tools in Total Joint Arthroplasty: A Systematic Review.

Systems review and quality improvement (QI) is a significant need within orthopaedic surgery. The focus of this paper is to systematically review QI principles utilized in total joint arthroplasty to determine most successful QI tools. A systematic search on MEDLINE/Pubmed, Embase, Cochrane Library and other sources was conducted from September 1991 through October 2018. The three primary improved outcomes from each article were recorded along with the date, author and subspecialty. Thirty-four eligible studies related to joint arthroplasty were identified for inclusion in the systematic review. The most common outcomes that were improved in these publications were: length of stay (LOS), cost, medication management, and patient education. Lean, clinical care pathways (CCP), plan-do-check-act (PDCA), and shared decision-making improved those metrics. Four metrics were found that were consistently improved by certain quality improvement tools: LOS, cost, medication management, and patient education. Further research is warranted to continue to build a framework for quality improvement in orthopaedic surgery. (Journal of Surgical Orthopaedic Advances 30(3):125-130, 2021).

What Is the Prevalence of Burnout, Depression, and Substance Use Among Orthopaedic Surgery Residents and What Are the Risk Factors? A Collaborative Orthopaedic Educational Research Group Survey Study.

BACKGROUND: Burnout and depression among healthcare professionals and trainees remain alarmingly common. In 2009, 56% of orthopaedic surgery residents reported burnout. Alcohol and illicit drug use are potential exacerbating factors of burnout and depression; however, these have been scarcely studied in residency populations. QUESTIONS/PURPOSES: (1) What proportion of orthopaedic residents report symptoms of burnout and depression? (2) What factors are independently associated with an orthopaedic resident reporting emotional exhaustion, depersonalization, low personal accomplishment, and depression? (3) What proportion of orthopaedic residents report hazardous alcohol or drug use? (4) What factors are independently associated with an orthopaedic resident reporting hazardous alcohol or drug use? METHODS: We asked 164 orthopaedic surgery programs to have their residents participate in a 34-question internet-based, anonymous survey, 28% of which (46 of 164) agreed. The survey was distributed to all 1147 residents from these programs, and 58% (661 of 1147) of these completed the survey. The respondents were evenly distributed among training years. Eighty-three percent (551 of 661) were men, 15% (101 of 661) were women, and 1% (nine of 661) preferred not to provide their gender. The survey asked about demographics, educational debt, sleep and work habits, perceived peer or program support, and substance use, and validated instruments were used to assess burnout (abbreviated Maslach Burnout Inventory), depression (Patient Health Questionnaire-2), and hazardous alcohol use (Alcohol Use Disorder Identification Test-Consumption). The main outcome measures included overall burnout, emotional exhaustion, depersonalization, low personal accomplishment, depression, and hazardous alcohol and drug use. Using the variables gathered in the survey, we performed an exploratory analysis to identify significant associations for each of the outcomes, followed by a multivariable analysis. RESULTS: Burnout was reported by 52% (342 of 661) of residents. Thirteen percent of residents (83 of 656) had positive screening results for depression. Factors independently associated with high emotional exhaustion scores included early training year (odds ratio 1.15; 95% confidence interval, 1.01-1.32; p = 0.03) unmanageable work volume (OR 3.13; 95% CI, 1.45-6.67; p < 0.01), inability to attend health maintenance appointments (OR 3.23; 95% CI, 1.69-6.25; p < 0.01), lack of exercise (OR 1.69; 95% CI, 1.08-2.70; p = 0.02), and lack of program support (OR 3.33; 95% CI, 2.00-5.56; p < 0.01). Factors independently associated with depersonalization included early training year (OR 1.27; 95% CI, 1.12-1.41; p < 0.01), inability to attend health maintenance appointments (OR 2.70; 95% CI, 1.67-4.35; p < 0.01), and lack of co-resident support (OR 2.52; 95% CI, 1.52-4.18; p < 0.01). Low personal accomplishment was associated with a lack of co-resident support (OR 2.85; 95% CI, 1.54-5.28; p < 0.01) and lack of program support (OR 2.33; 95% CI, 1.32-4.00; p < 0.01). Factors associated with depression included exceeding duty hour restrictions (OR 2.50; 95% CI, 1.43-4.35; p < 0.01) and lack of program support (OR 3.85; 95% CI, 2.08-7.14; p < 0.01). Sixty-one percent of residents (403 of 656) met the criteria for hazardous alcohol use. Seven percent of residents (48 of 656) reported using recreational drugs in the previous year. Factors independently associated with hazardous alcohol use included being a man (OR 100; 95% CI, 35-289; p < 0.01), being Asian (OR 0.31; 95% CI, 0.17-0.56; p < 0.01), single or divorced marital status (OR 2.33; 95% CI, 1.47-3.68; p < 0.01), and more sleep per night (OR 1.92; 95% CI, 1.21-3.06; p < 0.01). Finally, single or divorced marital status was associated with drug use in the past year (OR 2.30; 95% CI, 1.26-4.18; p < 0.01). CONCLUSIONS: The lack of wellness among orthopaedic surgery residents is troubling, especially because most of the associated risk factors are potentially modifiable. Programs should capitalize on the modifiable elements to combat burnout and improve overall wellbeing. Programs should also educate residents on burnout, focus on work volume, protect access to health maintenance, nurture those in the early years of training, and remain acutely aware of the risk of substance abuse. Orthopaedic surgery trainees should strive to encourage peer support, cultivate personal responsibility, and advocate for themselves or peers when faced with challenges. At a minimum, programs and educational leaders should foster an environment in which admitting symptoms of burnout is not seen as a weakness or failure. LEVEL OF EVIDENCE: Level II, prognostic study.

Corticosteroid Injections May Increase Retear and Revision Rates of Rotator Cuff Repair: A Systematic Review.

PURPOSE: To synthesize the clinical outcome data of preoperative and postoperative corticosteroid injections (CIs) and their effect on rotator cuff repairs (RCRs). METHODS: A systematic review was performed to identify studies that reported the results or clinical outcomes of RCRs in patients receiving either preoperative or postoperative CIs. The searches were performed using MEDLINE, Google Scholar, and Embase, and studies were chosen following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. RESULTS: A total of 11 studies were included with data for 176,352 shoulders: 6 studies involving 175,256 shoulders with data regarding preoperative CIs, 4 studies involving 1,096 shoulders with data regarding postoperative CIs, and 1 study with 212 shoulders containing preoperative and postoperative data. Preoperative CIs were found in 3 studies to increase the risk of revision surgery when administered within 6 months (odds ratio [OR], 1.38-1.82) and up to 1 year (OR, 1.12-1.52) prior to RCR, with revision rates in 2 studies being highest when patients received 2 or more injections (OR, 2.12-3.26) in the prior year. Postoperative CIs reduced pain and improved functional outcomes in 5 studies without increasing the retear rates (5.7%-19% for CI and 14%-18.4% for control) in most studies. CONCLUSIONS: CIs provide benefit by relieving pain and improving functional outcome scores. However, repeated preoperative CIs may increase retear rates and the likelihood of revision surgery. A lower frequency of CI and longer preoperative waiting period after CI should be considered to decrease such risks. Postoperative CIs several weeks after RCR do not appear to increase retear rates. LEVEL OF EVIDENCE: Level IV, systematic review of Level I through IV studies.

Patient Perception of Orthopedic Surgeon Reimbursement.

Significant attention has been directed at evaluating reimbursement rates to orthopedic surgeons for various surgical procedures. To evaluate patients' understanding of the surgeon reimbursement process, studies using patient surveys have been conducted to determine patients' perceptions of orthopedic surgeon compensation. To date, there has been no systematic review to consolidate the data of these studies. This study aimed to synthesize the findings of these individual studies across multiple subspecialties of orthopedic surgery to evaluate the potential discrepancy between how much patients believe orthopedic surgeons are reimbursed and the actual reimbursement rate. We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies that report findings of patient perceptions of orthopedic surgeon reimbursement for various procedures. Searches were conducted using MEDLINE through PubMed, Embase, and Scopus. Summary estimates of reimbursement discrepancies across subspecialties and overall were reported as unweighted averages of the individual study results within each group. Twelve studies were identified that met inclusion criteria, constituting 4309 surveys. These survey studies measured patients' perceptions of how much orthopedic surgeons are reimbursed for common procedures, including anterior cruciate ligament reconstruction, arthroscopic meniscectomy, carpal tunnel release, rotator cuff repair, multiple spine procedures and total shoulder, hip, and knee arthroplasty. It was found that patients reported reasonable surgeon's fees to be 11.2 times more than actual Medicare reimbursement. Among individual studies, the largest discrepancies were seen in total hip arthroplasty (26 times), whereas the smallest difference was in anterior cruciate ligament reconstruction (1.6 times). On average, patients estimated Medicare reimbursement rates to be 5.9 times higher than the actual surgeon reimbursement. Patients consistently overestimate how much orthopedic surgeons are reimbursed for common orthopedic procedures. The results of this systematic review suggest that patients may value these procedures more than what Medicare reimburses. Such information may help educate the public, direct policy, and increase transparency between orthopedic surgeons and patients.

Check-in Kiosks in the Outpatient Clinical Setting: Fad or the Future?

OBJECTIVES: Check-in kiosks are increasingly used in health care. This project aims to assess the effects of kiosk use upon check-in duration, point of service (POS) financial returns, and patient satisfaction. METHODS: Six kiosks were implemented in a large academic orthopedic clinic, and check-in duration for 8.5 months following implementation and POS returns for 10.5 months before and after implementation were analyzed. Consumer Assessment of Healthcare Providers and Systems Clinician and Group survey and self-devised surveys recorded patient satisfaction. RESULTS: Cumulatively, 28,636 kiosk-based patient encounters were analyzed. Compared with historical norms, check-in duration decreased 2 minutes, 47 seconds (P < 0.001). Daily gross and individual POS returns increased $532.13 and $1.89, respectively (P < 0.001). Satisfaction surveys were completed by 719 of 1376 consecutive patients (52% response rate), revealing 12% improvement (P < 0.001), but Consumer Assessment of Healthcare Providers and Systems Clinician and Group survey responses demonstrated no change (P = 0.146, 0.928, and 0.336). CONCLUSIONS: Kiosks offer to reduce check-in duration and increase POS revenue without negatively affecting patient satisfaction.

Os acromiale: systematic review of surgical outcomes.

BACKGROUND: The literature is unclear as to the optimal surgical management of a symptomatic os acromiale that has failed nonoperative treatment. Surgical options include excision, acromioplasty, and open reduction and internal fixation. The purpose of this study is to summarize the described methods and compare their reported outcomes with the goal to provide direction on how to surgically manage os acromiale. METHODS: We performed a systematic review of the current medical literature. Fifteen studies met all the inclusion criteria. Two hundred eleven total subjects (220 shoulders) underwent surgical treatment for a symptomatic os acromiale. There were 140 men and 71 women with a mean age of 49.6 ± 9.1 years. The mean follow-up duration was 40 ± 11.6 months. Surgical techniques used in the included studies were excision, acromioplasty, and open reduction with internal fixation. Concurrent surgical procedures performed were also included. RESULTS: Meso-os acromiale was the most common type (167 cases, 94.4%). The most common surgical technique was internal fixation (135 cases, 60.8%), with screw fixation being the majority (76 cases, 56.3%). Excision (65 cases, 29.3%) was the second most used technique. The most common concurrent surgical procedure performed was rotator cuff repair (125 cases, 56.3%), followed by distal clavicle excision (31 cases, 14%). CONCLUSIONS: All surgical techniques employed resulted in improvement in postsurgical clinical outcomes without any technique demonstrating superior results. Operative management of a symptomatic os acromiale that has failed initial nonoperative treatment leads to decreased symptoms and improvement in clinical outcomes.

Clinical outcomes following conservative and surgical management of floating shoulder injuries: a systematic review.

BACKGROUND: Floating shoulder is an uncommon injury characterized by fractures of the clavicle and ipsilateral scapular neck. No consensus exists on management. The purpose of this study was to analyze the existing literature on treatment and clinical outcomes of floating shoulder injuries to provide a baseline understanding of current treatment strategies of this injury. METHODS: A systematic review was performed to identity published literature on outcomes and management of floating shoulder injuries. Searches were performed using PubMed, Embase, and SCOPUS. RESULTS: Seventeen studies were identified that included data for 371 shoulders. The mean reported age was 39.4 years (range, 16-82) and the mean follow-up was 49.4 months (range, 6-312). The major mechanism of injury was motor vehicle accident (51%) followed by fall from height (16%). Of the 371 shoulders, 215 (58%) were treated surgically, whereas 156 shoulders (42%) were managed nonoperatively. The most commonly reported outcome score was the Constant-Murley score (9 studies), followed by the Herscovici Floating Shoulder Injury score (5 studies). The mean Constant-Murley score was 80% of ideal maximum for both shoulders treated surgically and those treated nonoperatively. CONCLUSION: Satisfactory outcomes can be expected following both surgical fixation and nonoperative management of floating shoulder injuries when appropriately individualized to the patient, as evidenced by clinical outcome scores. Floating shoulder injuries with significant displacement of the scapular neck may benefit from surgical fixation of both the clavicle and scapula fractures. In those with minimal or nondisplaced scapular neck fractures, good outcomes may be achieved when treated nonoperatively or with surgical fixation of the clavicle alone.

Attitudes and awareness of suture anchor cost: a survey of shoulder surgeons performing rotator cuff repairs.

BACKGROUND: The cost of health care in the United States accounts for 18% of the nation's gross domestic product and is expected to reach 20% by 2020. Physicians are responsible for 60%-80% of decisions resulting in health care expenditures. Rotator cuff repairs account for $1.2-$1.6 billion in US health care expenditures annually. The purpose of this study is to assess surgeons' cost awareness in the setting of rotator cuff repairs. The hypothesis is that practice environment and training affect cost consciousness and incentivization will lead to more cost-effective choices. METHODS: In this cross-sectional study, a 21-item survey was distributed via the email list services of the American Shoulder and Elbow Surgeons and Arthroscopy Association of North America. Data collected included demographics, variables regarding rotator cuff repair (technique, number of companies used, procedures per month), and knowledge of costs. RESULTS: Responses from 345 surgeons in 23 countries were obtained with the majority (89%) being from the United States. Most surgeons were "cost-conscious" (275, 70.7%). Of these surgeons, 62.9% are willing to switch suture anchors brands to reduce overall costs if incentivized. Cost-conscious surgeons were more likely to be fellowship trained in shoulder and elbow (51.81% vs. 38.57%, P = .048), be paid based on productivity (73.53% vs. 61.43%, P = .047), and receive shared profits (85.4% vs. 75%, P = .02). CONCLUSION: The majority of orthopedic surgeons are both cost-conscious and willing to change their practice to reduce costs if incentivized to do so. A better understanding of implant costs combined with incentives may help reduce health care expenditure.

Subscapularis sparing total shoulder arthroplasty through a superolateral approach: a radiographic study.

BACKGROUND: Most anatomic total shoulder arthroplasty (ATSA) techniques release and reattach the subscapularis tendon. The risk of failed healing is a widely recognized complication. The purpose of this study was to radiographically compare a traditional deltopectoral (DP) approach and a superolateral subscapularis sparing (SSS) technique through the rotator interval. METHODS: A single, independent, blinded, reviewer analyzed preoperative and postoperative radiographs of patients undergoing ATSA performed by a single surgeon. The reviewer assessed humeral head height, humeral head medial offset, humeral head diameter, head-neck angle, humeral head centering, and coracohumeral offset, and used the anatomic reconstruction index (ARI) to evaluate overall reconstruction quality. RESULTS: There were 70 SSS and 20 DP patients included. When comparing preoperative with postoperative differences, we found that there was no difference between groups in humeral head height (P = .19), humeral head medial offset (P = .38), and coracohumeral offset (P = .07). The DP group had a mean humeral head diameter oversizing of 1.4 mm, whereas the superolateral group had an undersizing of 2.8 mm (P < .001). The head-neck angle difference of the SSS approach was 2° greater than that found with the DP group (P < .001). The humeral head centering in the DP group was 7% displaced vs. 12% with the SSS group (P = .001) relative to the glenoid size. The ARI was 7.35 for the DP group and 6.93 for the SSS group (P = .50). DISCUSSION AND CONCLUSIONS: Radiographic comparison of these 2 ATSA techniques identified no statistical significant difference in 4 of 7 radiographic measurements and ARI. The SSS ATSA is a reasonable approach that yields similar radiographic measurements as a traditional DP total shoulder arthroplasty approach.

Outcome measures reported for the management of proximal humeral fractures: a systematic review.

BACKGROUND: The American Shoulder and Elbow Surgeons multicenter taskforce studying proximal humerus fractures reached no consensus on which outcome measures to include in future studies, and currently no gold standard exists. Knowledge of commonly used outcome measures will allow standardization, enabling more consistent proximal humerus fracture treatment comparison. This study identifies the most commonly reported outcome measures for proximal humerus fracture management in recent literature. METHODS: A systematic review identified all English-language articles assessing proximal humerus fractures from 2008 to 2018 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Review articles, meta-analyses, revision surgery, chronic injuries, studies with <15 patients, studies with <12 month follow-up, anatomic/biomechanical studies, and technique articles were excluded. Included studies were assessed for patient demographics and outcome scores, patient satisfaction, complications, range of motion, and strength. RESULTS: Of 655 articles, 74 met inclusion criteria. The number of proximal humerus fractures averaged 74.2 per study (mean patient age, 65.6 years). Mean follow-up was 30.7 months. Neer type 1, 2, 3, and 4 fractures were included in 8%, 51%, 81%, and 88% of studies, respectively. Twenty-two patient-reported outcome instruments were used including the Constant-Murley score (65%), Disabilities of the Arm, Shoulder, and Hand score (31%), visual analog scale pain (27%), and American Shoulder and Elbow Surgeons score (18%). An average of 2.2 measures per study were reported. CONCLUSION: Considerable variability exists in the use of outcome measures across the proximal humerus fracture literature, making treatment comparison challenging. We recommend that future literature on proximal humerus fractures use at least 3 outcomes measures and 1 general health score until the optimal scores are determined.

Outcomes With Overlapping Surgery at a Large Academic Medical Center.

OBJECTIVE: The aim of the study was to evaluate the efficiency and safety of overlapping surgery (OS) at a training institution by comparing it with nonoverlapping surgery (NO) with respect to operative time, mortality, readmissions, and complications. BACKGROUND: OS is the practice of an attending physician providing supervision to 2 surgeries that are scheduled at overlapping times. Recent media and government attention have raised concerns about this practice and the need for informed patient consent. METHODS: A population-based, retrospective, cohort study was conducted using data on operative procedures from January 1, 2014 to December 31, 2015 at a large tertiary academic center. Patients who had undergone surgery by attending surgeons who performed ≥10% of their cases overlapping were selected. Thirty-day mortality, readmission within 30 days, and 7 patient safety indicators (PSIs) were recorded. RESULTS: A total of 26,260 cases met our criteria for analysis for surgical time and 15,106 cases for outcomes. OS patients had an average case length of 2.18 hours compared with 1.64 hours among NO patients (P < 0.0001), a decreased risk of mortality [relative risk (RR) 0.42, 95% confidence interval (CI), 0.34-0.52, P < 0.0001), a decreased risk of readmission (RR 0.92, 95% CI, 0.86-0.98, P = 0.0148), and a decreased risk of experiencing any PSI (RR 0.67, 95% CI, 0.55-0.83, P = 0.0002). CONCLUSIONS: The present study confirms prior reports and addresses gaps in the literature regarding OS, such as the effect of resident involvement and the individual effect of OS in 13 different surgical specialties. The findings highlight the need for additional investigation and suggest that the practice of OS does not expose patients to increased risk of negative outcomes.

Subacromial Spacer Implantation for the Treatment of Massive Irreparable Rotator Cuff Tears: A Systematic Review.

PURPOSE: To synthesize and report the early clinical and radiographic outcomes associated with subacromial spacer use in patients with massive irreparable rotator cuff tears. METHODS: A systematic search on MEDLINE, Embase, and Cochrane Library databases was performed during February 2018. Included studies were evaluated regarding the level of evidence and quality using the methodological index for nonrandomized studies. Patient demographics, intraoperative findings, clinical and radiographic outcomes, and complications were recorded for each of the included studies. RESULTS: Seven eligible studies including 204 shoulders from 200 patients with subacromial spacer implantation were identified (6 Level IV studies and 1 Level III study). The mean methodological index for nonrandomized studies score for noncomparative studies was 11, whereas that of comparative studies was 15. The mean age of patients was 67.6 years, and the mean reported follow-up time was 19.4 months. All patients had Goutallier stage 3 and 4 fatty infiltration on magnetic resonance imaging. All studies reported consistent improvement in the total Constant score or American Shoulder and Elbow Surgeons score over the duration of follow-up. A total of 6 (3%) complications were reported in the included studies. Two studies detailed radiographic outcomes, with discrepant changes in the acromiohumeral interval. CONCLUSIONS: Patients undergoing subacromial spacer implantation for the treatment of massive irreparable rotator cuff tears have satisfactory outcomes at the 2- to 3-year follow-up with a low rate of complications. LEVEL OF EVIDENCE: Level IV, systematic review of 1 Level III and 6 Level IV studies.

Marijuana use and mortality following orthopedic surgical procedures.

Background: The association between marijuana use and surgical procedures is a matter of increasing societal relevance that has not been well studied in the literature. The primary aim of this study is to evaluate the relationship between marijuana use and in-hospital mortality, as well as to assess associated comorbidities in patients undergoing commonly billed orthopedic surgeries. Methods: The National Inpatient Sample (NIS) database from 2010 to 2014 was used to determine the odds ratios for the associations between marijuana use and in-hospital mortality, heart failure (HF), stroke, and cardiac disease (CD) in patients undergoing 5 common orthopedic procedures: total hip (THA), total knee (TKA), and total shoulder (TSA) arthroplasties, spinal fusion, and traumatic femur fracture fixation. Results: Of 9,561,963 patients who underwent one of the 5 selected procedures in the 4-year period, 26,416 (0.28%) were identified with a diagnosis of marijuana use disorder. In hip and knee arthroplasty patients, marijuana use was associated with decreased odds of mortality compared with no marijuana use (P < .0001) and increased odds of HF (P = .018), stroke (P = .0068), and CD (P = .0123). Traumatic femur fixation patients had the highest prevalence of marijuana use (0.70%), which was associated with decreased odds of mortality (P = .0483), HF (P = .0076), and CD (P = .0003). For spinal fusions, marijuana use was associated with increased odds of stroke (P < .0001) and CD (P < .0001). Marijuana use in patients undergoing total shoulder arthroplasty was associated with decreased odds of mortality (P < .001) and stroke (P < .001). Conclusions: In this study, marijuana use was associated with decreased mortality in patients undergoing THA, TKA, TSA, and traumatic femur fixation, although the significance of these findings remains unclear. More research is needed to provide insight into these associations in a growing surgical population.
