Advocacy: a reflection on my 30 years of orthopedic practice

As orthopedic surgeons, we have the responsibility for advocating for our patients and our profession, on the local, state, and federal levels. The American Academy of Orthopaedic Surgeons (AAOS) created the American Association of Orthopaedic Surgeons to allow for political advocacy. The Association Political Action Committee, OrthoPAC, was created in 1999 and has become an effective tool in our advocacy committee. The American Shoulder and Elbow Surgeons (ASES), along with many orthopedic subspecialty societies, has established an advocacy effort and works with the AAOS through the OrthoPAC as a member of the Advisor’s Circle, which is designed to provide AAOS Members’ group practices and specialty societies with a leadership role within the Political Action Committee of the American Association of Orthopaedic Surgeons (Orthopaedic PAC). If we are to preserve individual patient access to specialized musculoskeletal care, we must support state and federal advocacy efforts. This can be in the form of financial support or personal involvement in relationship building. I encourage all members of ASES, especially the younger ones, to support your state orthopedic societies, the ASES, and the AAOS in their advocacy efforts. The well-being of our patients and the future of our profession depend on you.

Translation, Transcultural Adaptation, and Validation of the Brazilian Portuguese Version of the Body Image Disturbance Questionnaire for Scoliosis (BR-BIDQ-S).

Objective The Body Image Disturbance Questionnaire for Scoliosis (BIDQ-S) for scoliosis derives from the Body Image Disturbance Questionnaire (BIDQ) with specific adaptation for scoliosis patients. Despite its significance and applicability, this instrument has never been translated into Brazilian Portuguese. The current study aimed to translate, transculturally adapt, and validate the BIDQ-S into Brazilian Portuguese. Methods BIDQ-S was translated and culturally adapted into Brazilian Portuguese using the American Association of Orthopedic Surgeons (AAOS) criteria. The questionnaire validation relied on internal consistency and comparison with the Cobb angle, Pediatric Quality of Life Inventory (PedsQL), and Scoliosis Research Society (SRS-22). The Brazilian version (BR-)BIDQ-S validation occurred in a sample of 35 adolescents with scoliosis waiting for specialized treatment. Results Internal consistency of the BR-BIDQ-S was 0.899 according to the Cronbach's index (i.e., virtually perfect). Although BR-BIDQ-S did not correlate with the Cobb angle, it presented correlations with the Physical, Emotional, and Social domains from the PedsQL and the Function/Activity domain from the SRS-22. Conclusion BR-BIDQ-S was reliable in evaluating the body image of adolescents with scoliosis, presenting an internal consistency of 0,899 (virtually perfect). Moreover, similar to the original instrument, it correlated with PedsQL and SRS-22.

Psychometric evaluation of the Chinese version of the attitudes, subjective norms, perceived behavioural control and intention to pursue a career in mental health nursing scale

AimTo adapt culturally and assess the reliability and validity of the Attitudes, Subjective Norms, Perceived Behavioural Control and Intention to Pursue a Career in Mental Health Nursing (ASPIRE) scale among Chinese nursing students. BackgroundMental health nurses make up a substantial proportion of the mental health workforce and are pivotal for improving access to professional mental health care. However, a shortage of mental health nurses persists across various countries. Although new nursing graduates have the potential to alleviate the labor shortages, there is currently no standardized tool specifically designed to measure nursing students' intentions to pursue a career in mental health nursing in China. DesignA quantitative and cross-sectional design. MethodsFollowing email authorization from the author, the Chinese version of the ASPIRE scale was translated following the cross-cultural adaptation process guidelines established by the American Association of Orthopedic Surgeons (AAOS). A questionnaire survey was conducted among 540 nursing students from three universities in Hunan Province from April 2023 to October 2023. Nine experts were invited to evaluate the content equivalence of each item. Item analysis, exploratory factor analysis, confirmatory factor analysis, internal consistency reliability and test-retest reliability were used to test reliability and validity. ResultsThe Chinese version of the ASPIRE scale retained 14 items and it has high content validity. Pearson correlation analysis revealed a statistically significant difference in the correlation between the total scores of the items (P < 0.001). Exploratory factor analysis indicated that the one-factor solution explained 65.82% of the total variance and confirmatory factor analysis results indicated a good fit (CMIN/DF = 2.64, RMSEA = 0.079, GFI = 0.908, IFI = 0.964, SRMR = 0.0326). The Cronbach's alpha coefficient for the scale was 0.958 and the test-retest coefficient was 0.783. ConclusionThe Chinese version of the ASPIRE scale has great reliability and validity and can be used for assessing Chinese nursing students' intention to pursue a career in mental health nursing.

Adaption and psychometric evaluation of the Hindi version of Neck Disability Index in the rural population of Northern India: A cross cultural study

Background To ensure the validity and therapeutic utility of the Neck disability index (NDI) scale, translations, cultural adaptations and psychometric evidence is necessary. This study aimed to address the absence of a suitable and validated Hindi version of the NDI for the rural population. The specific objectives were to translate, adapt, and evaluate the psychometric properties of the newly developed Hindi version of the NDI. Methods Following guidelines provided by the American Association of Orthopedic Surgeons, the original English NDI scale was cross-culturally adapted into Hindi. The adaptation process included translations (forward and backward), expert committee review, pre-testing and cognitive debriefing with 30 individuals experiencing chronic non-specific neck pain. The outcome of this process was the creation of the Hindi version of the NDI, termed NDI-Hi. Subsequently, NDI-Hi was administered to 211 participants with neck pain from multiple centers for psychometric testing. The evaluation involved test-retest reliability over a 48-hour interval, factor analysis, assessment of internal reliability measures, and criterion-related validity by comparing it with the NPAD-Hindi version. Results The NDI-Hi version exhibited favorable psychometric properties, including good test-retest reliability with an intra-class correlation coefficient (ICC) of 0.87. Internal consistency of the scale was high, indicated by Cronbach’s alpha coefficient (α) of 0.96. The standard error of measurement (SEM) was determined to be 2.58, and the minimal detectable change (MDC) was calculated to be 7.15. Furthermore, the NDI-Hi showed significant correlation with the NPAD-Hindi version, with a correlation coefficient (rho) of 0.86, and a p-value of less than 0.001. Conclusions The NDI-Hi demonstrated validity and reliability as an outcome tool for assessing neck disability. It can be effectively utilized in clinical practice and research settings involving Hindi-speaking individuals with chronic non-specific neck pain. The adapted scale is particularly well-suited for the rural Northern Indian Hindi-speaking population.

Psychometric Properties of the Persian Version of the Dizziness Handicap Inventory for Patient Caregivers in Children

Background and Aim: Questionnaires are useful tools for clinicians. This study aimed to translate the Dizziness Handicap Inventory for Patient Caregivers (DHI-PC) into Persian (DHI-PC-P) and assess its psychometric properties for children aged 5–12 years. Methods: This is a descriptive-analytical psychometrics study. After obtaining permission from the developers of the DHI-PC, translation into Persian and cross-cultural adaptation were done according to the international guidelines for self-assessment tools recommended by the American Association of Orthopedic Surgeons. Participants were 21 parents (mean age: 38.05 years, SD=6.1 years, 18 female) and their children with dizziness (mean age 8.69 years, SD=2.41 years, 9 female) between the ages of 5–12 years old. Face validity, content validity, and test-retest reliability at an interval of 14–21 days were evaluated for the DHI-PC-P. Results: The face validity was confirmed qualitatively by the experts’ opinions and quantitatively by calculating the item impact score. Content validity was confirmed by calculating the content validity index and the content validity ratio (0.97 and 0.86, respectively). The internal consistency was good (Cronbach’s alpha=0.90). For the test- retest reliability, the intraclass correlation coefficient was obtained 0.94, indicating an excellent reliability. Conclusion: The DHI-PC-P can be used clinically as a valid and reliable tool for children with dizziness aged 5–12 years. Keywords: Questionnaire; dizziness handicap inventory; validity; reliability; vertigo; children

Reliability and validity of an adapted Arabic version of Scoliosis Japanese Questionnaire-27 in Saudi Arabia

BackgroundThe Scoliosis Research Society SRS-22 questionnaire is a standard tool to assess the Health-Related Quality of Life (HRQoL) in scoliosis patients but, because of cultural differences limited use among Arabic patients. The aim is to perform a cross-cultural adaptation and validation of Arabic version of Scoliosis Japanese Questionnaire-27 and test it on Saudi patients with adolescent idiopathic scoliosis (AIS). MethodsThis a cross sectional study run between July 2021 and December 2022 recruited 194 patients. The cross-cultural adaptation process was performed using the American Association of Orthopedic Surgeons (AAOS) Outcomes Committee method. All patients had completed the Arabic version of Scoliosis Japanese Questionnaire-27 and SF-12 preoperatively and 3-month postoperatively. The validity and internal consistency were tested using the Intraclass correlation coefficient (ICC), Cronbach alpha, Pearson correlation coefficient, and confidence interval (CI). ResultsWe analyzed the result of 194 female adolescent patients. The average age is 14 ± 2.4 years (range from 10 to 21 years). The majority of patients have a Lenke type 1 curve (54 %). The overall Cronbach alpha (CA) of all domains of Scoliosis Japanese Questionnaire-27 is 0.92. However, the Cronbach alpha for the mental health (Q17,18,20,21,23,24) and, self-image (Q12-14,22,25,26) are 0.93 and 0.84 respectively. ConclusionThe Arabic version of Scoliosis Japanese Questionnaire-27 is a reliable and valid instrument and can be applied to evaluate the quality of life in patients with AIS.

Reliability and validity of an adapted Saudi Arabic version of scoliosis research society outcomes questionnaire (SRS-30) in Saudi Arabia.

To perform a cross-cultural adaptation and validation of Saudi Arabic (SA) version of SRS-30 and test it on Saudi patients with adolescent idiopathic scoliosis (AIS). A retrospective analysis of prospective collected data of 322 patients with AIS. The cross-cultural adaptation process was performed using the American Association of Orthopedic Surgeons (AAOS) Outcomes Committee method. A pre-test analysis was conducted on 30 patients. All patients had completed the SRS-22r and SF-12 preoperatively and 198 patients had completed the SA version of SRS-30 and SF-12 postoperatively twice at six weeks interval. The validity and internal consistency were tested using the interclass correlation coefficient (ICC), Cronbach alpha, person correlation coefficient, and confidence interval (CI). There are 288 (89.4%) girls and 34 (10.6%) boys and the average age is 15 ± 2.3years (range from 10-21years). The majority of patients have a Lenke type 1 curve (41%) and only 14% have a Lenke type 5 and 6. The overall Cronbach alpha (CA) of all SRS-30 domains is 0.87. However, the Cronbach alpha for the satisfaction, and function domains slightly lower than the original English questionnaire. The Saudi Arabic version of SRS-30 is a reliable and valid instrument and can be applied to evaluate the quality of life in patients with AIS.

Major acetabular defects: outcomes of first revision total hip arthroplasty using Kerboull cross-plate with allograft and cemented dual mobility cup at a maximum follow-up of fourteen years.

The use of dual mobility cups (DMC) has been shown to reduce hip instability after revision surgery. For severe acetabular bone loss, reconstruction with a Kerboull cross-plate and bone allograft would contribute to restoring native hip position and bone stock. Only two papers reported on the combination of Kerboull cross-plate with bone allograft and cemented DMC in revision total hip arthroplasty (THA). This is a monocentric retrospective study (28 cases) of first-time revision THA using such a construct in American Association of Orthopaedic Surgeons (AAOS) grade III and IV acetabular bone defect. Detailed demographic, clinical and radiographic results were recorded and evaluated. With a mean follow-up of six ± 3.63years, no case of instability was reported. The modified Harris Hip Score (mHHS) was 88.4 ± 10.1. No hook fracture or mechanical failure was observed. Non-progressive radiolucent lines were recorded. Osteointegration of the allografts was observed in all cases with a mean Grodet score of 7.9 ± 0.97. In first revision THA, the use of a Kerboull cross-plate with allograft and a cemented DMC in AAOS grade III and IV acetabular bone defects demonstrated excellent clinical and radiological outcomes with no recorded cases of dislocation or mechanical failure.

Translation and psychometric properties of the Gujarati version post-COVID functional status scale

The ‘Post COVID Functional Status Scale’ (PCFS) is an ordinal scale concentrating on the functional limitations to view the variety of post-COVID 19 outcomes and to measure the consequence of the infection other than death The adapted version of the PCFS Scale will be useful in tracking the post COVID functional status in the individuals who can comprehend the scale better in the Gujarati language. This study was carried out in a post-COVID-19 patient population at a government tertiary care hospital. The study was carried out according to the guidelines given by the American Association of Orthopaedic Surgeons. The methodology consisted of 3 Phases. Forward and backward translation, expert committee review, and usability testing on the participants who were asked to fill out the Gujarati version of the PCFS scale twice in Phase 1, 2, and 3 respectively.30 participants, both males, and females participated in the study. Cronbach’s α was used to calculate the internal consistency of the scale. The ICC was 0.99, which interprets as a very high correlation and stability of the scale.The Cronbach’s alpha was calculated for a population of 30 participants. On test 1 the value for Cronbach’s Alpha (ɑ1) was 0.821 and on the second test, the value was (ɑ2) 0.866. A linguistically and practically identical Gujarati PCFS Scale was formulated after a careful and systematic process, which offers a viable and trustworthy method for assessing the functionality of post-COVID-19 patients.

Informed Written Consent for Orthopaedic Trauma in the Emergency Setting at a Tertiary Referral Centre: A Closed-Loop Audit.

IntroductionThe purpose of this investigation was to perform an audit of the standards of consent forms in which patients sign prior to operative intervention for orthopaedic trauma in an emergency setting in our institution, with comparison to the ‘Orthopaedic Surgical Consent’ standards, as set by the American Association of Orthopaedic Surgeons (AAOS). If required, the investigator aimed to close the loop in this audit by educating orthopaedic surgeons on the necessary standards of obtaining written consent for orthopaedic trauma.MethodsFollowing being granted approval by our institutional audit committee, a pre-intervention cycle was performed to assess the quality of consent obtained in written format using electronic patient records in consecutive patients over a four-week period. Following the analysis of this data, an education session was provided for all orthopaedic doctors responsible for obtaining informed written consent from patients who are planned to undergo operative management of a soft tissue or bony injury by the trauma and orthopaedic service in the emergency setting. Thereafter, a post-intervention cycle was performed with subsequent descriptive analysis using the GraphPad software.ResultsIn the pre-intervention audit cycle, all included (n = 107) consent forms (100%) correctly included the patient’s name, date of birth (DOB) and institutional board number (BN). However, only 79 consent forms (74.5%) were completed without using abbreviations or acronyms of any kind, whilst 81 consent forms (76.4%) were completed without correctly stating the side or site of the planned intervention. In the post-intervention cycle, all included (n = 40) consent forms (100%) correctly included the patient’s name, DOB and institutional BN. Additionally, a total of 37 consent forms (92.5%) were correctly completed without using abbreviations or acronyms of any kind (74.5% versus 92.5%, p = 0.02). Furthermore, a total of 39 consent forms (97.5%) were completed correctly stating the side or site of the planned intervention (76.4% versus 97.5%, p = 0.0015).ConclusionThis closed-loop audit found that the quality of informed consent obtained by orthopaedic surgeons in the emergency setting might potentially be significantly improved with at least one virtual education session. Such simple education sessions may potentially improve the documentation of the planned potential operative intervention by orthopaedic surgeons for cases of orthopaedic trauma to ensure patient safety is optimised. As the turnover of non-consultant hospital doctors is high in university teaching hospitals, regular education sessions on such topics may introduce a cultural shift in maintaining high standards when marking and consenting patients in the emergency setting.

Cross-cultural adaptation of Cantonese (Hong Kong) Oswestry Disability Index version 2.1b.

Oswestry Disability Index (ODI) was established by Fairbank in 1989 to assess functional disabilities in low back pain (LBP). It was last updated in 2019 as ODI version 2.1b (ODI AU_2.1b). ODI was first translated into Simplified Chinese Oswestry Disability Index (CODI) in 2008 by Lue. The construct validity, internal consistency, level of agreement and the floor and ceiling effects of CODI were found unclear by Yao in 2016. This study will verify how well the adapted Cantonese-Hong Kong Oswestry Disability Index version 2.1b (HKCODI) aligns with ODI AU_2.1b in the Southern Chinese population. The translation of ODI AU_2.1b was performed according to guidelines from MAPI Research Trust and American Association of Orthopaedic Surgeons. Psychometric properties of HKCODI were tested statistically by Pearson's correlation, Cronbach's Alpha and Intraclass Correlation Coefficient (ICC). A total of 200 subjects (109 males, 91 females) aged from 15 to 85 (mean age = 58.91) with LBP scored from 3/10 to 10/10 in the Visual Analogue Scale (VAS) were recruited in the Occupational Therapy Department of a tertiary referral center. HKCODI demonstrated strong construct validity in comparing with Hong Kong Roland-Morris Disability Questionnaire (HKRMDQ) (r = 0.666, p = 0.000), Short Form Health Survey (SF-36) Physical Composite Summary (- 0.700, p = 0.000) and VAS (0.487, p = 0.000). Excellent internal consistency and test-retest reliability were confirmed with Cronbach's Alpha of 0.997 and ICC of 0.993 at 95% confidence level. Cross-cultural adaptation of ODI AU_2.1b has been translated and validated as HKCODI and Item-8 (Sex Life) was suggested to skip for patient older than 60. HKCODI is a fully self-administered and highly reliable tool in assessing the functional disability of patients with LBP in the Southern Chinese population.

Health Care Lobbying, Political Action Committees, and Spine Surgery.

Retrospective review. The aim of this study was to analyze the political contributions and strategies of the Political Action Committee (PACs) lobbying for the political interests of spine surgeons. In 2016, a presidential election year, $514,224,628 was spent on health care lobbying. Only 16% ($85,061,148) was on behalf of health professionals providing care. Below we chronicle the overlapping contributions between the three different physician-based Political Action Committee (PAC) lobbying entities as it relates specifically to spine surgery. Data were abstracted for the PACs of the American Association of Neurological Surgeons (AANS), American Association of Orthopedic Surgeons (AAOS), and the North American Spine Society (NASS). These data were obtained using OpenSecrets (opensecrets.org), and the Federal Election Commission (fec.gov) website. All data points were collected biannually from 2006 to 2018 and statistically analyzed as appropriate. In 2016, the AAOS PAC contributed $2,648,218, the AANS PAC $348,091, and the NASS PAC $183,612. After accounting for respective group size, the AAOS spent >2.34 times that of the AANS. Orthopedists were 3.84 times (95% confidence interval 3.42-4.3) more likely to donate to their PAC than neurosurgeons (P < 0.001) during the 2016 election. The majority of contributions among the three different lobbyist organizations were to federal candidates, followed by fundraising committees, and finally to the national party. Eighty-eight percent of AANS donations went to Republican candidates, whereas AAOS and NASS were 63% and 67%, respectively. From 2008 to 2016, the AAOS PAC had a highest political contributions spend per active member of parent organization ($126.39) as compared to AANS ($80.52) and NASS ($17.81). The AAOS had five surgeons for every donor to the AAOS PAC, whereas the AANS had 14 surgeons and NASS 38 members per each donor. The AANS had a higher percentage of Republican donations with 78.9% of donations going to Republicans as compared to 61.8% of AAOS contributions and 67.9% of NASS contributions. Spine surgery is unique in that three different physician-based lobbyist organizations seek to influence legislative priorities with the AAOS having the most substantial fiscal impact and greatest participation. Choreography of donation strategies is essential to maximize physician voice at the policy level. 5.

Returning to orthopaedic business as usual after COVID-19: strategies and options.

PurposeThe aim of this manuscript is to review the available strategies in the international literature to efficiently and safely return to both normal orthopaedic surgical activities and to normal outpatient clinical activities in the aftermath of a large epidemic or pandemic. This information would be beneficial to adequately reorganize outpatient clinics and hospitals to provide the highest possible level of orthopaedic care to our patients in a safe and efficient manner.MethodsA literature search was performed for relevant research articles. In addition, the World Health Organisation (WHO), the US Centers for Disease Control (CDC), American Association of Orthopaedic Surgeons (AAOS), the EU CDC and other government health agency websites were searched for any relevant information. In particular, interest was paid to strategies and advise on managing the orthopaedic patient flow during outpatient clinics as well as surgical procedures including the necessary safety measures, while still providing a high-quality patient experience. The obtained information is provided as a narrative review.ResultsThere was not any specific literature concerning the organization of an outpatient clinic and surgical activities and the particular challenges in dealing with a high-volume practice, in the afterwave of a pandemic.ConclusionAs the COVID-19 crisis has abruptly halted most of the orthopaedic activities both in the outpatient clinic and the operating room, a progressive start-up scenario needs to be planned. The exact timing largely depends on factors outside of our control. After restrictions will be lifted, clinical and surgical volume will progressively increase. This paper offers key points and possible strategies to provide the highest level of safety to both the orthopaedic patient and the orthopaedic team including administrative staff and nurses, during the start-up phase.Level of evidenceReview, Level V.

The Orthopaedic Political Action Committee: Growth and Influence Over 20 Years.

The Political Action Committee (PAC) of the American Association of Orthopaedic Surgeons, also known as the OrthoPAC, is one of the most powerful and well-respected healthcare PACs in Washington, DC. Since its inception in 1999, the OrthoPAC has advocated at the federal level for orthopaedic patients and orthopaedic surgery as a profession. This manuscript will familiarize the reader with PACs, the history and structure of the OrthoPAC, important accomplishments of the OrthoPAC, current legislative positions, and leadership/organization. We also review the various ways that orthopaedic surgeons can engage in advocacy for musculoskeletal care.

Geriatric Femoral Neck Fractures: Hemiarthroplasty Implant Trends Across a Health System From 2006 to 2018.

Introduction:Hemiarthroplasty is increasingly used for the treatment of geriatric femoral neck fractures in an effort to optimize value-based care. The current American Association of Orthopaedic Surgeons (AAOS) guidelines released in 2014 for the treatment of geriatric hip fractures recommend the utilization of monopolar cemented constructs. The purpose of this study was to evaluate hip hemiarthroplasty implant cost variability and implant selection trends from 2006 to 2018.Materials and Methods:A retrospective review of 940 geriatric hip fractures treated with hemiarthroplasty was conducted across 3 institutions from 2006 to 2018. Variables examined were construct type, surgeon, operative time, patient mortality, and implant cost. Statistical analysis consisted of multigroup comparative tests and multiple linear regression analyses to evaluate correlative measures.Results:The study population was 85.0 ± 7.9 years of age with a body mass index of 24.0 ± 5.5. A total of 33 (3.5%) patients were deceased at the 90-day postoperative mark and 45 (4.8%) patients at the 1-year mark. There was no statistical difference in terms of mortality between the 4 implant cohorts at the 90-day mark (P = .56) and 1-year mark (P = .24). The bipolar press-fit construct was the most expensive, US$3900.61 ± US$2607.54, and the monopolar cemented construct was the least expensive, US$2618.68 ± US$1834.16. The mean operative time was 6 minutes greater for press-fit implants, 93.6 ± 32.0, than cemented implants, 87.1 ± 33.6 (P = .02). The use of monopolar cemented implants increased from 12.1% to 83.3%, while bipolar press-fit decreased from 57.6% to 4.6% from 2013 to 2018.Discussion:The use of a bipolar and/or press-fit implant significantly increases construct cost despite little evidence in the literature of improved outcomes. Contrary to previous research, cemented implants do not increase the operative time.Conclusions:Encouragingly, selection of the most cost-conscience implant, monopolar cemented, has been increasing since 2014, which may reflect the influence of current AAOS guidelines.Level of Evidence:Diagnostic Level III.

Cross-cultural adaptation and validation of the Igbo language version of the stroke-specific quality of life scale 2.0.

Introductionavailability of the Stroke-Specific Quality of Life scale 2.0 (SS-QoL(E)) in Yoruba and Hausa, two of the three major indigenous languages in Nigeria have the potential to promote its uptake among these population, however, its non-availability in the Igbo languages makes its use restrictive among the south-eastern Nigerians. This study was aimed at cross-culturally adapting and assessing validity and reliability of the Igbo version of the SS-QoL.Methodsthe SS-QoL(E) was cross-culturally adapted to Igbo following the American Association of Orthopaedic Surgeons’ guideline. This involved forward and back-translations, expert committee review, pretesting and cognitive debriefing interview to produce the final Igbo version, SS-QoL(I). The validity and reliability test involved 50 consenting Igbo stroke survivors. The construct validity was assessed by administering SS-QoL(E) and SS-QoL(I) on all 50 respondents, while SS-QoL(I) was re-administered at 7-day interval to assess test-retest reliability. Each scale was administered in random order. Data were analysed using Spearman’s correlation, Wilcoxon’s signed-rank test, Cronbach’s alpha, Intra-class Correlation Coefficient (ICC), independent t-test and one-way ANOVA at p<0.05.Resultsrespondents’ domains scores on SS-QoL(E) and SS-QoL(I) did not differ significantly except in mobility and work (r=0.58 to 0.87; p=0.001). Cronbach’s alpha was 0.69 to 0.87 for domains scores. The ICC ranged from 0.48 to 0.84, while no significant differences was found across different age groups or gender for the domains or overall scores of SS-QoL(I).Conclusionthe Igbo version of the SS-QoL has limited alterations from the original version and has moderate to excellent validity and reliability values.

Update on Mentorship in Orthopaedic Resident Education: A Report from the American Orthopaedic Association.

Mentorship has been identified as an important element of educational and professional development for surgeons. An assessment that was conducted and reported through the American Association of Orthopaedic Surgeons (AAOS) in 2008 showed variability among U.S. residencies regarding the structure and requirements for mentorship during orthopaedic training; the assessment also demonstrated variability in residents' satisfaction with mentorship opportunities during their surgical training. An updated survey was developed and distributed via e-mail to residents attending the Resident Leadership Forum at the 2015 American Orthopaedic Association Annual Meeting to determine their views regarding the importance of mentorship, as well as their assessments of formal mentorship programs within their residencies. The updated data were compared with the prior survey results from 2008. A total of 149 (87.6%) of 170 residents responded to the survey. Of these, 34.9% (51 of 146) reported the existence of a formal mentorship program within their residency, as compared with 26.0% of residencies as stated in the 2008 report. One hundred percent of residents indicated that having a mentor during orthopaedic residency was either critical (63.7%, 93 of 146) or advantageous (36.3%, 53 of 146) to professional development as a surgeon; 74.7% (109 of 146) of residents reported currently having mentors, which appears to represent an increase from the prior report (51%, 258 of 506). However, the percentage of residents who reported being "very" satisfied (17.9%, 25 of 140) or "somewhat" satisfied (43.6%, 61 of 140) with their mentorship opportunities was almost identical to the prior report (61.9% [86 of 139] versus 61.0%, respectively). Overall, residents from programs with formal mentorship programs in place reported significantly higher satisfaction with their mentoring program/environment compared with those from programs without formal mentorship programs in place (3.98 versus 3.54, p = 0.026). Orthopaedic residents continue to overwhelmingly indicate that mentorship is an important component of residency education: 34.9% of residencies have a formal mentorship program, compared with 26.0% in the prior survey. Additionally, 74.7% of current residents reported having a mentor compared with 51% of residents in the prior study. Despite this difference, a very similar percentage of residents indicated that they were either "very" or "somewhat" satisfied with their mentorship experience. Residents from programs with formal mentorship programs reported significantly higher satisfaction with their mentorship programs compared with those without formal programs. These results support continued efforts toward improving mentorship opportunities within U.S. orthopaedic residency programs.

Review of Guidelines for Dental Antibiotic Prophylaxis for Prevention of Endocarditis and Prosthetic Joint Infections and Need for Dental Stewardship.

Dentists prescribe 10% of all outpatient antibiotic prescriptions, writing more than 25.7 million prescriptions per year. Many are for prophylaxis in patients with prosthetic joint replacements; the American Dental Society states that "in general," prophylactic antibiotics are not recommended to prevent prosthetic joint infections. Orthopedic surgeons are concerned with the risk of implant infections following a dental procedure and, therefore, see high value and low risk in recommending prophylaxis. Patients are "stuck in the middle," with conflicting recommendations from orthopedic surgeons (OS) and dentists. Unnecessary prophylaxis and fear of lawsuits amongst private practice dentists and OS has not been addressed. We review The American Heart Association/American College of Cardiology, American Dental Association, and American Association of Orthopedic Surgeons' guidelines on dental antibiotic prophylaxis for the prevention of endocarditis and prosthetic joint infections. We provide experience on how to engage private-practice dentists and OS in dental stewardship using a community-based program.

2061. Private Practice Dentists and Orthopedic Surgeons (PPD&amp;OS) Engage in a Novel Stewardship Forum: Consensus to Use Less Antibiotics Achieved

BackgroundThe American Dental Association (ADA) favors no antibiotic prophylaxis for joint implant patients (JIP), while the American Association of Orthopedic Surgeons’ (AAOS) guidance favors up to lifetime prophylaxis for JIP. Private practice dentists (PPD) represent 80% of all US dentists and to date, no one has attempted dental stewardship with PPD&OS to address this issue. Our purpose is to engage PPD&OS in the same room to address dental stewardship.MethodsA town hall community evening forum led by an infectious diseases pharmacist and physician, including an oral surgeon, OS, hospital lawyers, and physicians from the CDC. One hour of didactics was presented to 28 PPD&OS followed by a breakout session with interdisciplinary groups to address 2 cases and 10 thought provoking questions to get at rationale for answers. Team leaders presented answers for discussion and “next-steps” to engage more PPD&OS. A pre- and post-survey was administered.ResultsPPD&OS’ “next-steps” were: online continuing education webinar, develop a process to inform PPD&OS if patients develop CDI or a “superbug,” more presentations by ASP experts at local/national meetings, and use local media to engage consumers. The opportunity to meet and work through cases together was highly valued.ConclusionAn interdisciplinary community forum effectively allowed for consensus among PPD&OS to use fewer antibiotics for JIP receiving dental treatment. Fear of lawsuits impacts antibiotic use; as guidelines are updated and dental stewardship with PPD expands definitive recommendations and improved communications are key.
