Outcome of Open Reduction and Internal Fixation versus Hemiarthroplasty in Proximal Humerus Complex Fractures

Abstract Background: This study compares open reduction and internal fixation (ORIF) versus hemiarthroplasty (HA) in the management of complex proximal humerus fractures. Materials and Methods: Neer three- and four-part fracture-dislocations, surgical neck fracture-dislocations with severe articular impaction, and any head-split fracture treated surgically at our institution were studied retrospectively. Constant–Murley scores, Disability of the Arm, Shoulder, and Hand (DASH), American Shoulder and Elbow Surgeons (ASES) Shoulder, and 36-item Short-Form Health Survey (SF-36) scores were obtained and compared between ORIF versus HA treatment. Results: Thirty patients were included in the analysis: 15 treated with ORIF were compared to 15 treated with HA with an average follow-up of 60 months. The mean Constant score (72 ± 15 vs. 54 ± 19; P = 0.005), DASH score (13 ± 17 vs. 29 ± 18; P = 0.006), ASES score (87 ± 13 vs. 66 ± 22; P = 0.003), and SF-36 physical composite score (PCS) (50 ± 11 vs. 40 ± 11; P = 0.02) all favored the ORIF group. Because of the potential confounding variable posed by including younger patients, we performed a subgroup analysis of patients older than 50 years. In this group, the Constant, DASH, ASES, and PCS scores remained significantly better in the ORIF group. Conclusion: Results of this retrospective study show improved patient-reported outcomes and quality of life scores in patients undergoing ORIF for complex proximal humerus fractures as compared to patients undergoing HA, despite a higher revision rate in the ORIF cohort. When considering patients older than 50 years, outcomes after ORIF were better than HA.

Adherence to Clotting Factor Treatment and Association with Bleeding and Health-Related Quality of Life in Persons with Hemophilia

Introduction: Measuring patient adherence to prophylactic treatment with clotting factor in persons with hemophilia includes both subjective and objective measurements. There are limited studies conducted in adherence research using objective measures and a few studies revealed lack of correlation between subjective and objective adherence measurement. The study objectives are 1) to develop an objective adherent measurement; and 2) to assess it's association with bleeding and health-related quality of life (HRQoL) using the data collected from the Hemophilia Utilization Group Study Part VI (HUGS VI), which was an observational, non-interventional study investigating adherence to factor replacement therapy among persons with hemophilia A or B. Methods: HUGS VI enrolled participants from eight U.S. federally-supported hemophilia treatment centers in seven states (California, Colorado, Georgia, Indiana, Pennsylvania, Texas, and Washington) from 2015 to 2017. We enrolled eligible participants who either used standard half-life (SHL) products or used extended half-life (EHL) products for less than six weeks. We collected data on socio-demographics, bleeds, joint problems, and pain via surveys, as well as HRQoL, as measured by SF-12 at enrollment and at each three-month follow-up. We collected monthly factor prescription data from the clinical chart, and monthly factor dispensing records from the participants' pharmacy. We calculated factor treatment for the proportion of days covered (PDC) as the sum of the days of treatment available based on dispensing records, divided by the sum of the days of treatment prescribed based on prescription records for nine months post-enrollment. PDC ≥0.8 was considered an objective measure of adherence to factor treatment. The number of bleeds was summed from each of three quarterly follow-up surveys. We defined EHL users as participants who started an EHL product during the study period, either six weeks prior to enrollment or anytime during the nine months follow up. Association of PDC with nine months bleeds, ratings of chronic pain, and SF-12 scores in the nine-month follow-up were analyzed using Pearson correlation and Student T-Tests. Results: We analyzed a sample of 69 adults (age ≥18 years) with moderate or severe hemophilia using prophylactic treatment who completed at least baseline and nine-month follow-up surveys and had both prescription and dispensing records. Mean age was 28.9±10.3 (standard deviation) years, 91.3% were hemophilia A, and 65.2% were adherent to clotting factor treatment with PDC ≥0.8. EHL users were less likely to be adherent to the treatment than non-EHL users (adherence rate was 47.4% vs. 72.0%, p=0.06). PDC was significantly and negatively correlated with nine months of joint bleeds (correlation coefficient r=-0.30, p=0.01), and total bleeds (r=-0.33, p=0.026), but positively correlated with SF-12 physical composite score (r=0.32, p=0.009). PDC was not correlated with chronic pain (r=0.08, p=0.51) or SF-12 mental composite score (r=0.03, p=0.79). The participants who were adherent to factor treatment had fewer mean joint and total bleeds (2.6±4.1 vs. 1.3±2.1, p=0.08, and 4.9±5.6 vs. 2.9±3.8, p=0.07, respectively) than those non-adherent to treatment, although the differences did not reach statistical significance. Compared to participants who were adherent to treatment, non-adherent participants had a lower SF-12 physical composite score, with an approximately 5-point difference (43.4±10.6 vs. 48.0±9.1, p=0.07). Conclusions: As the data collection period occurred when EHL products became commercially available, treatment adherence may have led to treatment selection as participants switched from SHL to EHL products. Our data showed that participants who were non-adherent to treatment were more likely to be EHL users. Better adherence with higher PDC was moderately correlated with fewer bleeds, but higher HRQoL physical health composite score. The objective adherence measurement developed in this study should be further studied to investigate whether switching from SHL to EHL improves treatment adherence and its association with clinical outcomes.

The Veterans Rand-12 Physical Composite Score Prognosticates Postoperative Clinical Outcomes in Patients Undergoing Anterior Cervical Discectomy and Fusion

To determine prognostic value of preoperative Veterans RAND 12-Item Health Survey (VR-12) physical composite score (PCS) on outcomes in patients undergoing anterior cervical discectomy and fusion (ACDF). ACDF patients with preoperative VR-12 PCS formed 2 cohorts: VR-12 PCS <35 and VR-12 PCS ≥35. The following patient-reported outcome measures (PROMs) were gathered preoperatively and postoperatively up to 2 years: VR-12 mental composite score (MCS)/PCS, Neck Disability Index (NDI), Patient-Reported Outcomes Measurement Information System (PROMIS) PF, 9-Item Patient Health Questionnaire (PHQ-9), visual analog scale (VAS) neck/arm pain, and 12-Item Short Form Health Survey (SF-12) PCS/MCS. Comparing PROMs change with established thresholds determined achievement of minimum clinically important difference (MCID). Univariate analysis compared demographics, perioperative characteristics, and preoperative PROMs. Multivariable regression analysis compared postoperative PROMs and MCID achievement. Of 174 patients, 83 had VR-12 PCS <35. Preoperatively, patients with reduced PF displayed lower patient-reported outcome scores in NDI, PHQ-9, and SF-12 MCS (P ≤ 0.008), but not in VAS arm. At 6 weeks postoperatively, these patients continued to score lower in NDI (P ≤ 0.014) and SF-12 PCS (P ≤ 0.001), among others. By the final check, most scores remained lower (P ≤ 0.002) except for PHQ-9 and VAS arm (P > 0.05). Greater improvements at 6 weeks postoperatively were especially noted in patients with lower initial VR-12 PCS for NDI, PROMIS PF, and SF-12 PCS (P < 0.05). However, by final follow-up, only PROMIS PF showed noteworthy improvement (P= 0.19). Regarding MCID achievement, significant differences were largely absent except in NDI, where patients with reduced PF exhibited more MCID achievement (P= 0.016). ACDF patients with VR-12 PCS <35 experienced inferior PF, mental health, and disability postoperatively until final follow-up. There were no significant differences in postoperative improvement magnitude and MCID achievement. Results suggest that baseline VR-12 PCS in ACDF patients may indicate poorer PF, mental health, and disability postoperatively. However, VR-12 PCS does not limit extent of postoperative improvement.

Psychometric properties and general population reference values for PROMIS Global Health in Hungary

ObjectivesPatient-Reported Outcomes Measurement Information System–Global Health (PROMIS-GH) is a widely used generic measure of health status. This study aimed to (1) assess the psychometric properties of the Hungarian PROMIS-GH and to (2) develop general population reference values in Hungary.MethodsAn online cross-sectional survey was conducted among the Hungarian adult general population (n = 1700). Respondents completed the PROMIS-GH v1.2. Unidimensionality (confirmatory factor analysis and bifactor model), local independence, monotonicity (Mokken scaling), graded response model fit, item characteristic curves and measurement invariance were examined. Spearman’s correlations were used to analyse convergent validity of PROMIS-GH subscales with SF-36v1 composites and subscales. Age- and gender-weighted T-scores were computed for the Global Physical Health (GPH) and Global Mental Health (GMH) subscales using the US item calibrations.ResultsThe item response theory assumptions of unidimensionality, local independence and monotonicity were met for both subscales. The graded response model showed acceptable fit indices for both subscales. No differential item functioning was detected for any sociodemographic characteristics. GMH T-scores showed a strong correlation with SF-36 mental health composite score (rs = 0.71) and GPH T-scores with SF-36 physical health composite score (rs = 0.83). Mean GPH and GMH T-scores of females were lower (47.8 and 46.4) compared to males (50.5 and 49.3) (p < 0.001), and both mean GPH and GMH T-scores decreased with age, suggesting worse health status (p < 0.05).ConclusionThis study established the validity and developed general population reference values for the PROMIS-GH in Hungary. Population reference values facilitate the interpretation of patients’ scores and allow inter-country comparisons.

Injury-related emergency department visits and unplanned readmissions are associated with worse long-term mental and physical health

BackgroundThe risk factors for unplanned emergency department (ED) visits and readmission after injury and the impact of these unplanned visits on long-term outcomes are not well understood. We aim to: 1) describe the incidence of and risk factors for injury-related ED visits and unplanned readmissions following injury and, 2) explore the relationship between these unplanned visits and mental and physical health outcomes 6–12 months post-injury. MethodsTrauma patients with moderate-to-severe injury admitted to one of three Level-I trauma centers were asked to complete a phone survey to assess mental and physical health outcomes at 6–12 months. Patient reported data on injury-related ED visits and readmissions was collected. Multivariable regression analyses were performed controlling for sociodemographic and clinical variables to compare subgroups. ResultsOf 7,781 eligible patients, 4675 were contacted and 3,147 completed the survey and were included in the analysis. 194 (6.2%) reported an unplanned injury-related ED visit and 239 (7.6%) reported an injury-related readmission. Risk factors for injury-related ED visits included: younger age, Black race, a lower level of education, Medicaid insurance, baseline psychiatric or substance abuse disorder and penetrating mechanism. Risk factors for unplanned injury-related readmission included younger age, male sex, Medicaid insurance, substance abuse disorder, greater injury severity and penetrating mechanism of injury. Injury-related ED visits and readmissions were associated with significantly higher rates of PTSD, chronic pain and new injury-related functional limitations in addition to lower SF-12 mental and physical composite scores. ConclusionsInjury-related ED visits and unplanned readmissions are common after hospital discharge following treatment of moderate-severe injury and are associated with worse mental and physical health outcomes.

Does Baseline Severity of Arm Pain Influence Outcomes Following Single-Level Anterior Cervical Discectomy and Fusion?

Retrospective cohort. To assess preoperative arm pain severity influence on postoperative patient-reported outcomes measures (PROMs) and minimal clinically important difference (MCID) achievement following single-level anterior cervical discectomy and fusion (ACDF). There is evidence that preoperative symptom severity can affect postoperative outcomes. Few have evaluated this association between preoperative arm pain severity and postoperative PROMs and MCID achievement following ACDF. Individuals undergoing single-level ACDF were identified. Patients were grouped by preoperative Visual Analog Scale (VAS) arm ≤8 vs. >8. PROMs collected preoperatively and postoperatively included VAS-arm/VAS-neck/Neck Disability Index (NDI)/12-item Short Form (SF-12) Physical Composite Score (PCS)/SF-12 mental composite score (MCS)/Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF). Demographics, PROMs, and MCID rates were compared between cohorts. A total of 128 patients were included. The VAS arm ≤8 cohort significantly improved for all PROMs excepting VAS arm at 1-year/2-years, SF-12 MCS at 12-weeks/1-year/2-years, and SF-12 PCS/PROMIS-PF at 6-weeks, only (p ≤0.021, all). The VAS arm >8 cohort significantly improved for VAS neck at all timepoints, VAS arm from 6-weeks to 1-year, NDI from 6-weeks to 6-months, and SF-12 MCS/PROMIS-PF at 6-months (p ≤0.038, all). Postoperatively, the VAS arm >8 cohort had higher VAS-neck (6 weeks/6 months), VAS-arm (12 weeks/6 months), NDI (6 weeks/6 months), lower SF-12 MCS (6 weeks/6 months), SF-12 PCS (6 months), and PROMISPF (12 weeks/6 months) (p ≤0.038, all). MCID achievement rates were higher among the VAS arm >8 cohort for the VAS-arm at 6-weeks/12-weeks/1-year/overall and NDI at 2 years (p ≤0.038, all). Significance in PROM score differences between VAS arm ≤8 vs. >8 generally dissipated at the 1-year and 2-year timepoint, although higher preoperative arm pain patients suffered from worse pain, disability, and mental/physical function scores. Furthermore, clinically meaningful rates of improvement were similar throughout the vast majority of timepoints for all PROMs studied.

Sex Differences in Patient-Reported Outcomes and Range of Motion After Total Ankle Arthroplasty.

As the popularity of total ankle arthroplasty (TAA) increases, there is a growing need to examine the effects of sex on postoperative outcomes. This study compares patient-reported outcome measures and ankle range of motion (ROM) in the postoperative period, as stratified by sex. Patients who underwent TAA during 2013 to 2018 with a minimum follow-up of 2 years were included (N = 133). American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score, Visual Analog Scale (VAS), and 12-Item Short-Form Survey (SF-12) were administered preoperatively and at 6 months, 1 year, and 2 years postoperatively. ROM was recorded at these same time points. Preoperatively and at 6 months postoperatively, the cohorts did not differ in any of the measured outcomes. At 1 year postoperatively, females had lower SF-12 Physical Composite Scores (female = 44.1, male = 47.1, P = .019) and less plantarflexion (female = 20.5 degrees, male = 23.5 degrees, P = .029). By 2 years postoperative, females had lower AOFAS scores (female = 80.3, male = 85.4, P = .040). A greater complication rate amongst the female cohort approached significance at 18.6% versus 9% for males (P = .124). These results support TAA as a reliable means of treating ankle arthritis in both sexes, despite important differences. Understanding these outcome differences is critical for effectively managing expectations and treating both female and male populations. Level III: Retrospective cohort study.

Impact of Postoperative Length of Stay on Patient-Reported and Clinical Outcomes After Anterior Lumbar Interbody Fusion.

Existing literature has not yet evaluated the impact of postoperative length of stay (LOS) on patient-reported outcome measures (PROMs) and minimum clinically important difference (MCID) in patients undergoing anterior lumbar interbody fusion (ALIF). The authors investigates the influence of postoperative LOS following ALIF on PROMs and MCID achievement rates. A single-surgeon database was retrospectively reviewed for patients undergoing single-level ALIF. The following 2 cohorts were studied: patients with LOS <45 hours and patients with LOS ≥45 hours. The following PROMs were recorded at preoperative and 6-week, 12-week, 6-month, 1-year, and 2-year postoperative timepoints: visual analog scale (VAS) back and leg, Oswestry Disability Index (ODI), 12-item short form (SF-12) physical composite score (PCS), and patient-reported outcome measurement information system physical function. MCID achievement was compared by LOS grouping using χ 2 analysis. The rates of complications by LOS grouping and the relative risk among demographic and perioperative characteristics for a longer hospital stay of ≥45 hours were calculated. A total of 52 subjects were included in each cohort. LOS ≥45 hours demonstrated worse ODI at 6 weeks and SF-12 PCS preoperative and at 12 weeks (P ≤ 0.026, all). LOS <45 hours demonstrated greater MCID rates for all PROMs except VAS back (P ≤ 0.004, all). Postoperative urinary retention (POUR), fever, and total complications (P ≤ 0.003, all) were associated with increased LOS. Diabetes (P = 0.037), preoperative VAS neck ≥7 (P = 0.012), and American Society of Anesthesiologists classification ≥2 (P = 0.003) served as preoperative risk factors for postoperative stay ≥45 hours. Following single-level ALIF, patients with shorter LOS demonstrated significantly greater overall MCID achievement for most PROMs. POUR, fever, and total complications were associated with longer LOS and greater blood loss. Diabetes and higher preoperative leg pain were identified as risk factors for longer LOS. Patients undergoing ALIF with shorter LOS had greater MCID achievement for disability, physical function, and leg pain outcomes. Patients with greater preoperative leg pain and diabetes may be at risk for longer LOS.

Impact of Gender on Postsurgical Outcomes in Patients Undergoing Anterior Cervical Discectomy and Fusion.

Prior studies associate male gender with higher complication rates following anterior cervical discectomy and fusion (ACDF), but none has investigated gender influence on patient-reported outcome measures (PROMs) and minimal clinically important difference (MCID) following single-level ACDF. Patients undergoing primary, single-level ACDF were divided into female and male groups. Visual analog scale (VAS) neck/arm, Neck Disability Index (NDI), 12-item short form (SF-12) physical composite score (PCS), PROM information system physical function (PROMIS-PF), and veterans RAND 12-item (VR-12) health survey PCS were collected preoperatively and postoperatively. Simple linear regression analysis evaluated the predictive capability of gender on PROMs. Multiple regression analysis was performed to determine the effects of gender on mean PROMs while accounting for insurance type. Established MCID values determined achievement rates across PROMs. χ 2 analysis compared MCID achievement by gender. A total of 179 women and 134 men were included. Cohorts differed in insurance type, length of stay, and discharge day (P ≤ 0.017, all). Women improved in PROMs at all timepoints (P ≤ 0.049, all) except SF-12 PCS 6 weeks and PROMIS-PF 6 weeks. Men improved in PROMs at all timepoints (P ≤ 0.042) except VAS arm 2 years, SF-12 PCS 6 weeks and 2 years, PROMIS-PF 6 weeks, and VR-12 PCS 6 weeks. Women demonstrated higher SF-12 PCS (P = 0.043) and VR-12 PCS (P = 0.035) 2 years. Multiple regression determined that VAS neck and arm from 6 weeks to 6 months, NDI from preoperative to 6 months, SF-12 PCS and VR-12 PCS from preoperative to 12 weeks, and PROMIS-PF preoperative, 6 weeks, and 6 months were significantly affected by gender and insurance status (P ≤ 0.031, all). MCID achievement rate did not differ for any PROM between genders. Women reported significantly higher long-term physical function health (SF-12 PCS and VR-12 PCS) compared with men, while disability and pain did not differ. Nevertheless, no significant differences in MCID achievement were observed for any PROM studied. Gender does not appear to play a significant role in clinically meaningful recovery following single-level ACDF. Gender has little value in prognostication for determining clinically meaningful recovery after single-level ACDF.

P137. Preliminary analysis on the influence of workers’ compensation status on outcomes of anterior lumbar interbody fusion at L5-S1

<h3>BACKGROUND CONTEXT</h3> Few studies have focused on outcomes among Workers' Compensation (WC) claimants undergoing anterior lumbar interbody fusion (ALIF). <h3>PURPOSE</h3> To determine the influence of WC on perioperative outcomes, patient-reported outcome measures (PROMs) and attainment rates of minimal clinically important difference (MCID) among patients undergoing single-level ALIF at L5S1. <h3>STUDY DESIGN/SETTING</h3> Retrospective. <h3>PATIENT SAMPLE</h3> A retrospective surgical database of an attending spine surgeon was utilized to identify patients with WC insurance undergoing single-level ALIF at L5S1. One-hundred and nine patients were included, with 82 in the non-WC and 27 in the WC cohort. <h3>OUTCOME MEASURES</h3> PROM data for visual analog scale (VAS) back/leg, Oswestry Disability Index (ODI), 12-Item Short Form (SF-12) Physical Composite Score (PCS) and Patient Reported Outcome Measurement Information System physical function (PROMIS-PF) was obtained preoperatively and at 6-weeks, 12-weeks, 6-months, 1-year and 2-years following ALIF. <h3>METHODS</h3> Patients were divided into groups based on insurance status: WC vs non-WC (including patients with private insurance or Medicare/Medicaid). Demographic and perioperative information was evaluated between insurance groups using student's t-test for independent samples for continuous variables and chi-squared test for categorical variables. Mean PROMs were compared with student's t-test for independent samples. Comparisons of preoperative and postoperative PROM values were evaluated with paired sample t-tests. Patients who achieved an improvement in PROM score greater than or equal to established threshold values were marked as achieving MCID. WC and non-WC groups were compared in MCID attainment rates across PROMs with chi-squared analyses. <h3>RESULTS</h3> A greater proportion of the non-WC cohort were Caucasian, while a significantly greater proportion of the WC cohort were African American and Hispanic (p=0.001). Significantly more patients in the WC cohort were smokers (p<0.001). Non-WC patients improved significantly from preoperative to postoperative timepoints of 6-months through 2-years for PROMIS-PF and SF-12 PCS, 6 weeks through 1 year for VAS back, 6 months/1 year for VAS leg and 12 weeks through 1-year for ODI (p≤0.048, all). WC patients improved significantly at postoperative timepoints for PROMIS-PF at 6 weeks (p=0.029), SF-12 PCS at 12 weeks (p=0.018), VAS back from 6 weeks to 6 months, and VAS leg at 6 months, only (p≤0.029, all). Mean VAS back scores were significantly greater in the WC cohort at 6 months and 1 year (p≤0.013, both), mean VAS leg scores were significantly greater in the WC cohort at 1 year (p=0.029), and mean ODI scores were significantly higher in the WC cohort at preoperative through 1 year (p≤0.040, all). With the exception of higher MCID achievement for VAS back at 12 weeks (p=0.037), no other differences in attainment rates were observed for any PROM at any time point or for the overall postoperative period. <h3>CONCLUSIONS</h3> Among patients receiving ALIF, WC insurance was more prevalent among patients identifying as Hispanic and African American, along with smokers. While physical function scores were similar between groups, long-term pain and disability (throughout the entire postoperative period) were significantly higher among patients with WC. MCID achievement, however, was largely comparable for all PROMs between WC and non-WC study groups. <h3>FDA DEVICE/DRUG STATUS</h3> This abstract does not discuss or include any applicable devices or drugs.

Impact of Body Mass Index on Postsurgical Outcomes for Workers' Compensation Patients Undergoing Minimally Invasive Transforaminal Lumbar Interbody Fusion.

Increased morbidity associated with obesity imposes a greater financial burden on companies that provide insurance to their employees. Few studies have investigated the relationship between body mass index (BMI) and patient-reported outcome measures (PROMs) for minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) in the workers' compensation (WC) population. WC patients who underwent a primary, single-level MIS TLIF were included/grouped according to BMI: nonobese (<30 kg/m2); obese I (≥30, <35 kg/m2); severe + morbid (≥35). PROMs were collected pre- and postoperatively: visual analog scale (VAS), Oswestry Disability Index (ODI), 12-Item Short Form (SF-12) physical composite score (PCS), and Patient-Reported Outcome Measurement Information System physical function (PROMIS-PF). BMI predictive power grouping on PROMs was evaluated using simple linear regression. Established minimum clinically important difference values were used to compute achievement rates across PROMs using logistic regression. A total of 116 nonobese, 70 obese I, and 61 severe + morbid patients were included. Demographics among BMI grouping significantly differed in gender, hypertensive status, and American Society of Anesthesiologists score (P ≤ 0.037, all). Operative time was significantly different in perioperative values among BMI grouping (P ≤ 0.001). Increased BMI was significantly associated with greater VAS back at 12 weeks and 2 years (P ≤ 0.026, all), greater ODI preoperatively at 12 weeks and 6 months (P ≤ 0.015, all), and decreased PROMIS-PF at 12 weeks (P ≤ 0.011, all). Mean PROMs between obese I and severe + morbid cohorts differed in SF-12 PCS at 12 weeks, only (P = 0.050). ODI overall was the only parameter for which minimum clinically important difference was achieved among BMI cohorts (P ≤ 0.023). WC patients with increased BMI were more likely to develop significant back pain and disability at numerous postoperative timepoints compared with nonobese individuals. Our findings highlight the weight management importance within WC population to minimize back pain and disability following MIS TLIF, but provide a sense of reassurance with comparable clinical improvement regardless of BMI. When considering the effect of weight, surgeons may incorporate these findings in managing patient expectations in the WC population undergoing lumbar spine surgery.

Self-Reported Injury History and Health-Related Quality of Life in Competitive, Collegiate Baton Twirlers.

Injury epidemiology and health-related quality of life (HRQOL) have not been researched in baton twirlers. This cross-sectional study described time-loss injuries sustained by competitive collegiate baton twirlers, identified the relationship between training volume and injuries, and established injury impact on HRQOL. An online survey was used to collect activity volume, number and characteristics of time-loss injuries experienced within a 12-month window, and HRQOL via the Short Form-36. Current injury status was addressed to place participants into categories: no injury history (No Injury), history of injury but no symptoms (Injury Hx, No Sx), and currently injured (Current Injury). One hundred forty-two participants met the inclusion criteria. One hundred twenty-eight (90%) participants experienced a time-loss injury with 295 total reported injuries (2.1±1.4; range 1-9 injuries). Sixty-two percent of all reported injuries were still producing symptoms. There was a high average reported injury severity score (6.3±2.3). The most commonly affected area was the hip/thigh (30%), followed by the knee (15%) and ankle (14%). The Current Injury group had worse SF-36 bodily pain (p=0.003), vitality domains (p=0.001), and physical composite score (p=0.015) compared to the No Injury group. Both the No Injury and Injury Hx, No Sx groups performed better than the Current Injury group on physical function (p=0.007 and 0.02, respectively). Competitive collegiate baton twirlers experience the majority of injuries in the lower extremity which cause prolonged physical and non-physical symptoms.

Neck Disability at Presentation Influences Long-Term Clinical Improvement for Neck Pain, Arm Pain, Disability, and Physical Function in Patients Undergoing Anterior Cervical Discectomy and Fusion

To compare perioperative characteristics, patient-reported outcome measures (PROMs) and minimum clinically important difference (MCID) achievement after anterior cervical discectomy and fusion (ACDF) in patients stratified by preoperative neck disability. The Neck Disability Index (NDI) assesses a patient's self-perceived neck disability and is often used to assess the efficacy of cervical surgical intervention. Our study (a retrospective cohort study) evaluates how preoperative severity of patient neck disability influences postoperative clinical improvement after ACDF. Primary, single-level, or multilevel ACDF procedures were included. PROMs were administered at preoperative/6 week/12 week/6 month/1 year/2 year time points and included Patient-Reported Outcome Measurement Information System-Physical Function (PROMIS-PF), visual analog scale (VAS) for neck and arm pain, NDI, and 12-Item Short-Form (SF-12) Physical Composite Score (PCS). Patients were grouped according to preoperative NDI <50 (mild to moderate neck disability) or NDI ≥50 (severe neck disability). Demographics/perioperative characteristics/postoperative complications/mean PROMs/MCID achievement rates were compared using χ2 or Student t test. Postoperative improvement from preoperative baseline within each cohort was assessed with paired-samples t test. MCID achievement was determined by comparing ΔPROMs with established thresholds. A total of 225 patients were included, 150 NDI <50 and 75 NDI ≥50. The NDI ≥50 cohort was significantly younger (P= 0.002). Cohorts did not differ for spinal disease/operative duration/estimated blood loss/postoperative length of stay/postoperative narcotic consumption/adjacent segment disease rate/1-year arthrodesis rate/6-month pseudarthrosis rate. Postoperative VAS pain score on postoperative day 0 and 1 was significantly increased in the NDI ≥50 cohort (P<0.048, all). Postoperative complication rates did not differ. All mean PROMs differed at all time points (P<0.043, all). The NDI <50 patient cohort significantly improved from preoperative baseline for all PROMs and time points except SF-12 PCS/Patient-Reported Outcome Measurement Information System-Physical Function at 6 weeks. The NDI ≥50 cohort significantly improved for all PROMs and time points except SF-12 PCS at 6 weeks. The NDI ≥50 cohort showed a greater proportion achieving MCID for NDI at 6 weeks/2 years/overall (P<0.037, all). Both cohorts showed significant long-term clinical improvement for neck pain/arm pain/physical function/neck disability, although patients with severe preoperative neck disability reported inferior mean scores for these outcomes at all time points.

Depressive symptoms before and after abdominoplasty among post-bariatric patients – a cohort study

The majority of post-bariatric patients suffer from excess skin after weight loss, impairing physical, psychosocial and mental health. The abdomen is the most common location for excess skin, and abdominoplasty is the most commonly required reconstructive procedure. Abdominoplasty removes excess abdominal skin and attenuates related symptoms, but knowledge regarding mental health-related effects is scarce. Here, we aimed to evaluate the symptoms and severity of depression before and after abdominoplasty in post-bariatric patients and to analyse the relationships between depressive symptoms, quality of life (QoL) and experience of excess skin. We enrolled 110 former obese patients undergoing abdominoplasty. Three questionnaires evaluating the symptoms of depression (Beck Depression Inventory (BDI-II)), experience of excess skin (Sahlgrenska Excess Skin Questionnaire (SESQ)) and QoL (36-item Short-Form Health Survey (SF-36)) were completed preoperatively and 1 year postoperatively. After abdominoplasty, symptoms of depression (BDI sum score) significantly decreased (5.8 vs. 3.0, p = .037). Scores on three BDI questions improved (p < .05), and the SESQ score normalised (p < .001), while the SF-36 score was unaffected. The BDI sum score was moderately correlated with the SF-36 mental composite score (preoperatively, r s = −0.69; postoperatively, r s = −0.66) and fairly correlated with the SF-36 physical composite score (r s = 0.32, r s = 0.26). The correlation between the BDI sum and SESQ scores was poor preoperatively (r s = −0.106) and fair postoperatively (r s = 0.232). The results indicate that abdominoplasty may reduce symptoms of depression in post-bariatric patients. However, the procedure did not affect SF-36 scores. Further studies are required to validate these results.

The impact of the COVID-19 pandemic on functional and mental health outcomes after trauma

BackgroundThe COVID-19 pandemic has led to decreased access to care and social isolation, which have the potential for negative psychophysical effects. We examine the impact of the pandemic on physical and mental health outcomes after trauma. MethodsPatients in a prospective study were included. The cohort injured during the pandemic was compared to a cohort injured before the pandemic. We performed regression analyses to evaluate the association between the COVID-19 pandemic and physical and mental health outcomes. Results1,398 patients were included. In adjusted analysis, patients injured during the pandemic scored significantly worse on the SF-12 physical composite score (OR 2.21; [95% CI 0.69–3.72]; P = 0.004) and were more likely to screen positive for depression (OR 1.46; [1.02–2.09]; P = 0.03) and anxiety (OR 1.56; [1.08–2.26]; P = 0.02). There was no significant difference in functional outcomes. ConclusionsPatients injured during the COVID-19 pandemic had worse mental health outcomes but not physical health outcomes.

Sun Salutation yoga in patients with subacute low back pain: a feasibility study

IntroductionThe roles of yoga in improving symptoms in chronic low back pain (LBP) have been established. However, evidence of Sun Salutation yoga feasibility in subacute LBP is lacking. This feasibility study examined the adherence, safety, and potential effect size of Sun Salutation yoga in improving pain, functional disability, and quality of life among patients with subacute LBP.MethodsOverall, 20 patients with subacute LBP (65% females, age: 35 ± 10 years) were enrolled in a 6-week Sun Salutation program. The protocol adherence and safety were self-reported by participants during weekly monitoring. Pain was assessed with visual analogue scale (VAS) and numeric rating scale (NRS), functional disability with Oswestry Disability Index (ODI) and Roland-Morris Questionnaire (RMQ), while quality of life with the Short Form Health Survey (SF-12). Pre- and post-intervention data were analysed by using the paired t-test or Wilcoxon signed-rank test per data distribution. Effect size was evaluated.ResultsAll patients adhered to the study protocol and no adverse effects were reported. Pain, functional disability, and quality of life improved significantly after the intervention. Effect sizes were very large for pain (3.87 and 3.97 for VAS and NRS), functional disability (1.94 and 3.24 for ODI and RMQ), and quality of life (2.34 and 4.62 for SF-12 physical and mental composite score).ConclusionsThe adherence and safety of Sun Salutation yoga in subacute LBP patients were demonstrated, with large effect sizes for improving pain, functional disability, and quality of life. Randomized controlled trials are recommended to confirm the findings.

Influence of Preoperative 12-Item Short Form Mental Composite Score on Clinical Outcomes in an Isthmic Spondylolisthesis Population Undergoing Minimally Invasive Transforaminal Lumbar Interbody Fusion

To determine preoperative 12-Item Short Form Health Survey (SF-12) Mental Component Summary (MCS) influence on minimally important clinical difference (MCID) and patient-reported outcome measures in patients with isthmic spondylolisthesis receiving minimally invasive transforaminal lumbar interbody fusion. Patients with isthmic spondylolisthesis undergoing primary, single-level minimally invasive transforaminal lumbar interbody fusion at L5-S1 were retrospectively identified and divided into preoperative SF-12 MCS <50 and SF-12 MCS ≥50 groups. Visual analog scale (VAS) back/leg, Oswestry Disability Index (ODI), SF-12 Physical Composite Score (PCS), and Patient-Reported Outcome Measurement Information System physical function (PROMIS-PF) were assessed. Improvements from preoperative score were analyzed via paired samples t test. Patient-reported outcome measures and MCID attainment between groups were evaluated using linear regression and χ2, respectively. SF-12 MCS <50 and SF-12 MCS ≥50 groups included 35 and 26 patients, respectively. SF-12 MCS < 50 group had inferior scores for all VAS back time points except 6 weeks, all VAS leg time points except 6 weeks/1 year, all ODI time points, SF-12 PCS at 6 months/2 years, and PROMIS-PF at preoperative/6 months (all P ≤ 0.049). SF-12 MCS <50 group improved for VAS back/leg to 1 year, ODI and SF-12 PCS from 12 weeks to 1 year, and PROMIS-PF at 1 year only (all P ≤ 0.047). SF-12 MCS ≥50 group improved for VAS back from 12 weeks to 1 year, SF-12 PCS 6 months to 2 years, and VAS leg, ODI, and PROMIS-PF 12 weeks to 2 years (all P ≤ 0.018). MCID attainment differed for ODI at 6 weeks and PROMIS-PF at 12 weeks only (both P ≤ 0.035). Patients with SF-12 MCS <50 demonstrated fewer long-term improvements from preoperative to 2 years and inferior patient-reported outcome measures at most time points for pain and disability following minimally invasive transforaminal lumbar interbody fusion. MCID attainment largely did not differ by preoperative mental functioning.

Nutrition, Physical Activity Management Approaches Delivered by Nurse Practitioner-led Care Effect on the Outcomes of Care for Adult Subjects with Cardiovascular Disease: A Meta-analysis

Background: Cardiovascular disease is the very common disease characterized. It may cause unpleasant symptoms as well as increases the person's risk of disability. With an ageing population, increasing rates of cardiovascular disease and limited access to specialists, new methods of care, like nurse practitioners need to be assessed to meet patient specific needs and provide sustainable care. We performed a meta-analysis to evaluate the effect of nurse practitioner-led care on the outcomes of care for adult subjects with cardiovascular disease. Methods: A systematic literature search up to October 2021 (between 2000 and 2021) was done and 8 studies included 4019 subjects with cardiovascular disease at the start of the study; 2064 of them were provided with nurse practitioner-led care and 1955 were standard care. They were reporting relationships about the effect of nurse practitioner-led care on the outcomes of care for adult subjects with cardiovascular disease. We calculated the odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) to assess the effect of nurse practitioner-led care on the outcomes of care for adult subjects with cardiovascular disease using the dichotomous and continuous methods with a random or fixed-effect model. Results: Nurse practitioner-led care had significantly lower 30-day readmission for cardiovascular disease (OR, 0.63; 95% CI, 0.47-0.86, p=0.004) compared to standard care in subjects with cardiovascular disease. However, nurse practitioner-led care had no significant difference in length of stay after cardiac surgery (MD, -1.27; 95% CI, -3.72-1.19, p=0.31), health-related quality of life: SF-36 physical composite score (MD, 0.21; 95% CI, -0.75-1.17, p=0.67), and health-related quality of life: SF-36 mental composite score (MD, -0.79; 95% CI, -2.65 -1.08, p=0.41) compared to standard care in subjects with cardiovascular disease. Conclusions: Nurse practitioner-led care had significantly lower 30-day readmission for cardiovascular disease; however, nurse practitioner-led care had no significant difference in length of stay after cardiac surgery, and health-related quality of life: SF-36 physical composite score, and SF-36 mental composite score compared to standard care in subjects with cardiovascular disease. Further studies are required to validate these findings.

How Do Patient-Reported Outcomes Vary Between Lumbar Fusion Patients with Complete Versus Incomplete Follow-Up?

We sought to assess differences in patient-reported outcome measures (PROMs) between patients who do and do not follow up for 2 years after lumbar fusion. Primary, elective, single-level anterior lumbar interbody fusion, lateral lumbar interbody fusion, or transforaminal lumbar interbody fusion procedures were identified. Patients were grouped by 2-year PROM follow-up completion. Mean and delta PROM scores for visual analog scale (VAS) back and leg, Oswestry Disability Index (ODI), short-form (SF)-12 Physical Composite Score (PCS), and Mental Composite Score (MCS) were computed for both groups preoperatively and postoperatively. Minimum clinically important difference (MCID) achievement was determined for PROM scores using established threshold values. Linear and logistic regression assessed mean and ΔPROM scores as predictors of 2-year follow-up completion and compared MCID achievement between groups, respectively. We included 316 lumbar fusion patients. PROM scores were more favorable for complete follow-up patients for 6-month VAS back (P= 0.003), 6-month and 1-year ODI (P ≤ 0.027, both), and 6-week and 6-month SF-12 PCS (P ≤ 0.015, both). Six-month VAS back (P= 0.007); 6-month and 1-year ODI (P ≤ 0.028, both); 6-week, 6-month, and 1-year SF-12 PCS (P ≤ 0.041, all); and 6-week SF-12 MCS (P ≤ 0.028, both) significantly predicted 2-year follow-up. ΔPROMs significantly differed between groups at 1 year for ΔVAS leg (P= 0.029), ΔODI (P= 0.013), and ΔSF-12 MCS (P= 0.004). One-year ΔVAS leg (P= 0.035), ΔODI (P= 0.011), and ΔSF-12 MCS (P= 0.003) significantly predicted follow-up. MCID achievement for ΔPROMs significantly differed between groups for 6-week VAS leg (P= 0.035), overall ODI (P= 0.034), and SF-12 PCS from 12 weeks through 1 year (P ≤ 0.011, all) and overall (P < 0.001). Patients with full follow-up demonstrated significantly more favorable outcome scores and improvement in pain, disability, and physical function at several postoperative time points.
