The Unseen Strain: Investigating the Awareness of Rhinoplasty Surgeons Regarding Their Spine Health.

Musculoskeletal pain is a common occupational health problem among surgeons that can affect work productivity and quality of life. The aim of the study was to investigate the prevalence and causes of back pain among rhinoplasty surgeons, evaluate their routine practice, and identify unique risk factors. A further goal was to measure functional disabilities with the Total Disability Index (TDI) questionnaire. A structured online questionnaire was distributed to plastic surgeons performing rhinoplasty internationally. The questionnaire comprised sections on biodata, routine practice posture, length of practice, surgical duration, and the history of surgery or hospitalization related to these issues. In the second part of the survey, participants were asked to complete the TDI questionnaire. The prevalence of back pain was reported by 93.6% of surgeons, with low back pain being the most common (76.7%). The average pain intensity for low back pain was 44.8 ± 26.8. The mean TDI score was calculated as 31 ± 12.1, with 58.2% of surgeons experiencing mild to moderate disability. Significant associations were found between musculoskeletal pain severity and disability index and factors such as BMI, exercise, years of rhinoplasty practice, number of surgeries performed per week, and average procedure length. Interestingly, only 16.4% of rhinoplasty surgeons had previous ergonomic training or education. Musculoskeletal issues related to the spine are prevalent among rhinoplasty surgeons. It is imperative to educate surgeons about this underestimated health problem, provide proper physical rehabilitation targeting ergonomic concerns, and make changes to current practices to address this issue effectively.

Validation of the Total Disability Index (TDI) in French Version

IntroductionThe Total Disability Index (TDI) questionnaire has been developed to provide a more complete assessment of low back and neck pain, as they frequently co-occur. This study aimed at validating the TDI questionnaire in French, to determine if it could be used in France. HypothesisThe TDI French version is valid, reproducible and comparable to the English version. MethodsThis multicentric study prospectively included French-speaking volunteers, both patients admitted for spine surgery in two specialized spine centers and healthy individuals. Healthy subjects were recruited among students of an engineering school and medical staff. A booklet was given to the participants containing a Lumbar and Cervical Visual Analog Scale (respectively LVAS and CVAS), and the French versions of Oswestry Disability Index (ODI), Neck Disability Index (NDI) and TDI questionnaires. Statistical analysis included Cronbach's α calculation for internal consistency assessment, correlation analysis with ODI and NDI items for convergent validity, principal component analyses and factor analysis. Discriminant validity was assessed by comparing healthy subjects and patients using Student's t tests, and floor and ceiling effects search. Results71 participants were included, with 34 (48%) healthy volunteers and 37 (52%) patients. Mean age was 45.2±19.6 years and 57% of the cohort were males. Internal consistency was good: Cronbach's α was calculated at 0.96 (95%CI: [0.95–0.98]). For each TDI item, a high correlation was found with ODI corresponding items, between 0.81 and 0.97 (p<0.001), and good correlation with NDI items, ranging from 0.65 to 0.96 (p<0.001). TDI correlated also with LVAS and CVAS (respectively 0.70 and 0.65, p<0.001). Principal component analyses indicated good correlation between the TDI items and between each item and TDI total score. Factor analysis indicated two main factors explaining 77% of TDI variance, constituted by all TDI items. Regarding discriminative validity, healthy subjects and patients presented significantly different TDI scores (p-values ≤0.01 for each item). Barplot representations of each TDI item revealed no major floor nor ceiling effects. ConclusionThis study confirms the reliability, feasibility and validity of the Total Disability Index questionnaire in its French version. Its validation allows its use in France. Level of evidenceII.

Digital Survey Assessment of Factors Associated with Musculoskeletal Complaints Among US Ophthalmologists.

PurposeTo quantify features of musculoskeletal (MSK) complaints among US ophthalmologists and analyze factors related to symptom severity.MethodsCornea, glaucoma, retina, and comprehensive practitioners were invited to complete a web-based survey via email. Data on demographics, practice and procedural volumes, wellness activities, job stress, MSK health, the Total Disability Index (TDI), and ergonomics were collected. Significance testing was performed to evaluate factors related to TDI score.ResultsOf the 245 ophthalmologists contacted, 58.8% (n = 144) responded at least in part to the survey. Pain episodes were reported in 81.4% (n = 83) of 102 respondents, with 48.1% (n = 49) experiencing daily or weekly attacks. The neck, low back, and shoulders were commonly affected, yet only 57.1% (n=20) of those with shoulder pain reported a corresponding diagnosis. The mean TDI score was 6.2 ± 7.3%, indicating minimal disability related to the spine. Demographics, volume metrics, and wellness hours were each not significantly associated with TDI score (p > 0.05). Higher job stress ratings were reported by those who experienced more frequent pain attacks (p = 0.02) and those with higher TDI scores (p = 0.001). Greater difficulty with clinic, laser, and surgery job tasks was observed in respondents with higher TDI scores (p < 0.001, p = 0.005, and p < 0.001) and more bodily pain locations (p = 0.002, p = 0.002, and p = 0.001). Respondents who pursued practice modifications (p = 0.03) and treatments (p = 0.01) to reduce or prevent pain had higher mean TDI scores, and 94.2% of respondents (n = 97) were interested in learning more about ergonomics.ConclusionMild MSK complaints were highly prevalent among the surveyed ophthalmologists, and a similar trend could be expected for other US ophthalmologists. Greater frequency and severity of pain may contribute to physician burnout. There may be underdiagnosis of MSK pathology yet also high demand for ergonomic strategies and MSK treatments, suggesting a need for practical solutions.

Does psychological resilience mediate the relation between daily functioning and prefrailty status?

Understanding of prefrailty's relationship with limitations in activities of daily living (ADLs) moderated by psychological resilience is needed, as resilience might support ADLs' maintenance and thus protect against frailty. Therefore, this study aims to analyze the influence of psychological resilience (using the Connor-Davidson Resilience Scale; CD-RISC) on the relation between ADLs and frailty status of older individuals (i.e. prefrail versus robust). Cross-sectional design. UZ Brussels, Belgium. Robust (Fried 0/4;n = 214; Age = 82.3 ± 2.1yrs) and prefrail (Fried 1-2/4; n = 191; Age = 83.8 ±3.2yrs) community-dwelling older individuals were included. Frailty scores were obtained from weight loss, exhaustion, gait speed, and grip strength. A total Disability Index (DI) expressed dependency for basic (b-), instrumental (i-), and advanced (a-)ADLs. Mediation was investigated by estimating direct and indirect effects of all levels of ADLs and CD-RISC total score on prefrailty/robustness using a stepwise multiple regression approach. Prefrailty/robustness significantly correlated with a-ADL-DI (point-biserial correlation (rpb) = 0.098; p<0.05). Adjusted for age and gender, the a-ADL-DI (p<0.05) had a significant protective direct effect against prefrailty. No effects were found with the CD-RISC total score. Less limitation in a-ADLs is a directly correlated factor of prefrailty and might represent a higher likelihood of robustness.

Prefrailty: The Relationship Between Daily Activities and Social Participation in Older Persons.

To analyze prefrailty's relationship with limitations in activities of daily living (ADLs) and restrictions in social participation. Robust (Fried 0/4; n = 214; Mage = 82.3 years [SD ±2.1]) and prefrail (Fried 1-2/4; n = 191; Mage = 83.8 years [SD ±3.2]) community-dwelling older individuals were included. Frailty scores were obtained from weight loss, exhaustion, gait speed, and grip strength. A total disability index (DI) expressed dependency for basic (b-), instrumental (i-), and advanced (a-)ADLs. Total participation score, being a member, total number of memberships, being a board member, level of participation, membership over time, volunteering, and formal participation represented social participation. Logistic regression retained age (OR = 1.224; 95% CI = [1.122, 1.335]), sex (OR = 3.818; 95% CI = [2.437, 5.982]), and a-ADL-DI (OR = 1.230; 95% CI = [1.018, 1.486]) as variables significantly related to prefrailty (68.3%; χ2 = 68.25; df = 3; p < .001). Subtle limitations in a-ADLs, higher age, and being a man were associated with prefrailty, revealing the possible role of personal and culturally related a-ADLs as red flags for (pre)frailty.

Validation of the recently developed Total Disability Index: a single measure of disability in neck and back pain patients.

Neck and back pain are highly prevalent conditions that account for major disability. The Neck Disability Index (NDI) and Oswestry Disability Index (ODI) are the two most common functional status measures for neck and back pain. However, no single instrument exists to evaluate patients with concurrent neck and back pain. The recently developed Total Disability Index (TDI) combines overlapping elements from the ODI and NDI with the unique items from each. This study aimed to prospectively validate the TDI in patients with spinal deformity, back pain, and/or neck pain. This study is a retrospective review of prospectively collected data from a single center. The 14-item TDI, derived from ODI and NDI domains, was administered to consecutive patients presenting to a spine practice. Patients were assessed using the ODI, NDI, and EQ-5D. Validation of internal consistency, test-retest reproducibility, and validity of reconstructed NDI and ODI scores derived from TDI were assessed. A total of 252 patients (mean age 55 years, 56% female) completed initial assessments (back pain, n = 115; neck pain, n = 52; back and neck pain, n = 55; spinal deformity, n = 55; and no pain/deformity, n = 29). Of these patients, 155 completed retests within 14 days. Patients represented a wide range of disability (mean ODI score: 36.3 ± 21.6; NDI score: 30.8 ± 21.8; and TDI score: 34.1 ± 20.0). TDI demonstrated excellent internal consistency (Cronbach's alpha = 0.922) and test-retest reliability (intraclass correlation coefficient = 0.96). Differences between actual and reconstructed scores were not clinically significant. Subanalyses demonstrated TDI's ability to quantify the degree of disability due to back or neck pain in patients complaining of pain in both regions. The TDI is a valid and reliable disability measure in patients with back and/or neck pain and can capture each spine region's contribution to total disability. The TDI could be a valuable method for total spine assessment in a clinical setting, and its completion is less time consuming than that for both the ODI and NDI.

201 - Total Disability Index (TDI): A Single Functional Status Measure in Patients with Neck and/or Back Pain

Developing the Total Disability Index Based on an Analysis of the Interrelationships and Limitations of Oswestry and Neck Disability Index.

Retrospective. This study assessed the feasibility of combining Oswestry and Neck Disability Index (ODI and NDI) into 1 shorter "Total Disability Index" (TDI) from which reconstructed scores could be computed. ODI and NDI are not pure assessments of disability related to back and neck, respectively. Because of similarities/redundancies of questions, ODI scores may be elevated in neck-pain patients and the converse is true for NDI in back-pain patients. Spine patients completed ODI and NDI, and complaints were recorded as back pain (BP), neck pain (NP), or both (BNP). Questionnaire scores were compared across cohorts via descriptives and Spearman (ρ) correlations. In exploring the feasibility of merging ODI/NDI, TDI was constructed from 9 ODI and 5 NDI items. Extracting questions from TDI, reconstructed 9-item rODI and 10-item rNDI indices were formed and compared with true ODI/NDI. There were a total of 1207 patients: 741 BP, 134 NP, and 268 BNP. Mean ODI was 37 ± 21 and mean NDI was 32 ± 21. Patients with concurrent BP and NP had significantly more disability. Seventy-eight patients of 134 (58%) patients with NP only had at least "moderate disability" by ODI and 297 of 741 (40%) patients with back pain only, had at least "moderate disability" by NDI. ODI versus NDI correlation was ρ = 0.755; ODI versus reconstructed rODI correlated at ρ = 0.985, and NDI versus reconstructed rNDI correlated at ρ = 0.967 (P < 0.01). Elevated ODI/NDI scores in patients with isolated complaints show that disability in 1 region affects scores on both surveys. This study constructed a 14-item TDI that represents every domain of ODI/NDI with exception of ODI "Sex Life." From this TDI, reconstructed scores correlated near perfectly with true scores. TDI provides a more global assessment of spinal disability and is a questionnaire that reduces the time burden to patients. The TDI allows for simultaneous assessment of back, neck, and global spinal disability.

The advanced activities of daily living: a tool allowing the evaluation of subtle functional decline in mild cognitive impairment.

Assessment of advanced activities of daily living (a-ADL) can be of interest in establishing the diagnosis of Alzheimer's disease (AD) in an earlier stage, since these activities demand high cognitive functioning and are more responsive to subtle changes. In this study we tested a new a-ADL tool, developed according to the International Classification of Functioning, Disability and Health (ICF). The a-ADL tool is based on the total number of activities performed (TNA) by a person and takes each subject as his own reference. It distinguishes a total disability index (a-ADL-DI), a cognitive disability index (a-ADL-CDI), and a physical disability index (a-ADL-PDI), with lower score representing more independency. We explored whether these indices allow distinction between cognitively healthy persons, patients with Mild Cognitive Impairment (MCI) and patients with mild AD. Participants were on average 80 years old (SD 4.6; 66-90), were community dwelling, and were diagnosed as (1) cognitively healthy subjects (n=26); (2) patients with MCI (n = 17), or (3) mild AD (n = 25), based upon extensive clinical evaluation and a set of global, cognitive, mood and functional assessments. The a-ADL-tool was not part of the clinical evaluation. The a-ADL-CDI was significantly different between the three groups (p<.01). The a-ADL-DI was significantly different between MCI and AD (p<.001). The tool had good psychometrical properties (inter-rater reliability; agreement between patient and proxy; correlations with cognitive tests). Although the sample size was relatively small, ROC curves were computed for the a-ADL-DI and a-ADL-CDI with satisfactory and promising results. The a-ADL-CDI and a-ADL-DI might offer a useful contribution to the identification and follow up of patients with mild cognitive disorders in an older population.

A booklet was given to the participants containing a Lumbar and Cervical Visual Analog Scale (respectively LVAS and CVAS), and the French versions of Oswestry Disability Index (ODI), Neck Disability Index (NDI) and TDI questionnaires. Statistical analysis included Cronbach's α calculation for internal consistency assessment, correlation analysis with ODI and NDI items for convergent validity, principal component analyses and factor analysis. Discriminant validity was assessed by comparing healthy subjects and patients using Student's t tests, and floor and ceiling effects search.71 participants were included, with 34 (48%) healthy volunteers and 37 (52%) patients. Mean age was 45.2 ± 19.6 years and 57% of the cohort were males. Internal consistency was good: Cronbach's α was calculated at 0.96 (95%CI: [0.95–0.98]). For each TDI item, a high correlation was found with ODI corresponding items, between 0.81 and 0.97 (p < 0.001), and good correlation with NDI items, ranging from 0.65 to 0.96 (p < 0.001). TDI correlated also with LVAS and CVAS (respectively 0.70 and 0.65, p < 0.001). Principal component analyses indicated good correlation between the TDI items and between each item and TDI total score. Factor analysis indicated two main factors explaining 77% of TDI variance, constituted by all TDI items. Regarding discriminative validity, healthy subjects and patients presented significantly different TDI scores (p-values ≤ 0.01 for each item). Barplot representations of each TDI item revealed no major floor nor ceiling effects.This study confirms the reliability, feasibility and validity of the Total Disability Index questionnaire in its French version. Its validation allows its use in France.II.
