The association between body mass index and physical function in adult burn survivors: A Burn Model System National Database study

IntroductionAn area of rehabilitation research in burns is the impact of co-morbidities on disease trajectory. Obesity is a comorbidity of increasing public health concern, but its role remains controversial regarding burn injury and physical recovery. Our aim was to evaluate the association between body mass index (BMI) categories as a measure of obesity at discharge and self-reported physical function (PF) during recovery of adult burn survivors. MethodsThis is a retrospective study on data collected by four major US burn centers, which contribute to the Burn Model System National Database. The data included BMI obtained at hospital discharge and self-reported PF-mobility, using the PROMIS measures assessed at 6, 12, and 24 months after burn. Subjects were classified into weight status categories based on BMI: underweight (BMI <18.5), normal weight (18.5 ≤ BMI <25), overweight (25 ≤ BMI <30), obesity class 1 (30 ≤ BMI <35), obesity class 2 (35 ≤ BMI <40), and obesity class 3 (BMI ≥40). Mixed-effects linear regression models were used to assess the association between BMI categories and PF scores over time, adjusted for patient and injury characteristics. ResultsA total of 496 adult burn patients aged 47 ± 16 years were included, with mean total body surface area (TBSA) burned of 18 ± 19 % and mean BMI at discharge of 28 ± 7 kg/m2. PROMIS PF scores significantly improved over time in the recovery phase after burn (time effect, p < 0.001). Compared to overweight burn patients, normal-underweights exhibited lower PF score by an average of 4.06 units (p = 0.001) but scores increased linearly by an estimated 0.17 units per month (p = 0.01) over the 24 months after discharge. Similarly, compared to overweight burn patients, class 1 obese reported lower PF score by a mean 2.67 units (p = 0.07) but PF increased linearly by 0.15 units per month (p = 0.07) over the 24 months after discharge. These findings were independent of the effects of age at discharge, sex, TBSA burned, and hand and leg burn. ConclusionBeing overweight was associated with improved and faster recovery of PF scores compared to normal, underweight, and obese burn patients during long-term recovery. Hence, our data suggests that long-term recovery and restoration of PF in adult burn survivors is not compromised by a small excess in body weight.

Disparities in stereotactic radiosurgery practice patterns for treatment of brain metastases: A large national cancer database study.

11094 Background: Brain metastases (BM) portend high mortality rates. While whole brain radiation therapy (WBRT) is a commonly used treatment strategy for BM, stereotactic radiosurgery (SRS) has less neurocognitive toxicity with comparable survival. The objective of this study was to compare treatment practice patterns for SRS vs WBRT using a large national hospital database. Methods: The National Cancer Database (NCDB) was queried for patients ≥18 years treated with radiotherapy (RT) for a BM diagnosis between 2004-2017 and with known follow-up. 12 cancers were included based on highest prevalence including: breast, colorectal, kidney/bladder, liver, lung, lymphoma, melanoma, oral cavity, pancreas, prostate, and thyroid. Patients were grouped by first course RT modality (SRS vs WBRT) confirmed by fraction number (SRS: 1-5; WBRT: 5-15). Multivariable logistic regression assessed predictors of SRS as adjusted odds ratios (aOR) with 95% confidence intervals (95%CI). Analyses were adjusted for patient and cancer characteristics. Results: Of 88,539 patients with BM, 17,734 (18%) received SRS. Median age was 64 years. Most patients were White (84%), diagnosed in 2011-2017 (58%), with a higher income (55%), more education (55%), and Medicare/Medicaid (58%). The most common cancer treated with RT for BM was lung (86%). Patients were less likely to be treated with SRS if they were Hispanic (aOR=0.85; 95%CI=0.76-0.96), lower income (aOR=0.90; 95%CI=0.86-0.95), lower education (aOR=0.87; 95%CI=0.83-0.91), with Medicare/Medicaid (aOR=0.83; 95%CI=0.79-0.87) or no insurance (aOR=0.46; 95%CI=0.41-0.51), at a Midwest hospital (aOR=0.74; 95%CI=0.71-0.78; vs Northeast), and at a community (aOR=0.28; 95%CI=0.25-0.30; vs academic) or comprehensive community cancer program (aOR=0.50; 95%CI=0.47-0.52). Patients were more likely to be treated with SRS if they were older (aOR=1.01; 95%CI=1.01-1.01), diagnosed in 2011-2017 (aOR=2.39; 95%CI=2.30-2.49; vs 2004-2010), lived farther from the hospital (aOR=1.09; 95%CI=1.07-1.11), and received chemotherapy (aOR=1.41; 95%CI=1.35-1.47). SRS was most often used to treat BM from primary colorectal cancer (aOR=1.99; 95%CI=1.65-2.40), endometrial cancer (aOR=1.52; 95%CI=1.08-2.10), kidney/bladder cancer (aOR=3.09; 95%CI=2.68-3.55), and melanoma (aOR=2.74; 95%CI=2.39-3.14), while less often used to treat BM from lymphoma (aOR=0.18; 95%CI=0.11-0.30), vs breast primary cancers. Conclusions: In one of the largest BM studies with nearly 90,000 US patients, disparities in SRS treatment patterns were identified. On adjusted analysis, SRS was less likely to be used for patients who were of Hispanic ethnicity, lower income, lower educational attainment, without private insurance, and treated at community centers. The data highlight populations with cancer and BM who may benefit from increased access to SRS.

Factors influencing the mortality risk of heart failure in patients receiving antineoplastic immunotherapy: A national inpatient database study 2016-2020.

e24011 Background: Immunotherapy is increasingly being used for management of solid and lymphoproliferative tumors due to their more desirable side effect profile as compared to traditional cancer therapies. However, these medications are associated with cardiac complications and little is known about the factors influencing the prognosis in these patients. Methods: This is a retrospective analysis of the National Inpatient Database from 2016 to 2020 using the International Classification of Diseases (ICD) 10 codes performed with STATA BE 18.0. Chi square test was used for crude analysis and multivariate logistic regression was performed to assess the risk of inpatient death among cancer patients with heart failure receiving immunotherapy. Results were adjusted for potential confounders like age, gender, race, hypertension, diabetes, coronary artery disease, smoking, and alcohol consumption. Multicollinearity of the model was assessed using Variance Inflation Factor (VIF) post-estimation test. Results: Out of 5166 cancer patients receiving immunotherapy with a mean age of 43.63 土 26.33 years and 41% females, 45 patients had heart failure. Logistic regression showed that heart failure was significantly associated with mortality (LR 𝜒² 38.74, p value &lt; 0.001) on adjusting for potential confounders. Although the effect size was small, increased age (OR 1.025, CI 1.01-1.04) had a significantly higher risk of mortality. Patients belonging to the female gender and white, hispanic, and asian races had a lower risk of mortality while those belonging to the african american race and those with coronary artery disease had a higher mortality risk, although not statistically significant. Diabetes and alcohol consumption had a fourfold and sixfold increased risk of mortality respectively. Hypertension and smoking that are known to increase mortality risk in heart failure patients showed a paradoxically protective effect in this cohort. Conclusions: This study highlights the importance of risk stratification and prognostication among patients with heart failure receiving antineoplastic immunotherapy. Increased age, african american race, diabetes, alcohol consumption, and coronary artery disease have shown an increased mortality risk in these patients. [Table: see text]

Incidence and risk factors of postoperative delirium following hepatic resection: a retrospective national inpatient sample database study

BackgroundPostoperative delirium (POD) is a common complication after major surgery and can cause a variety of adverse effects. However, no large-scale national database was used to assess the occurrence and factors associated with postoperative delirium (POD) following hepatic resection.MethodsPatients who underwent hepatic resection from 2015 to 2019 were screened using the International Classification of Diseases (ICD) 10th edition clinical modification code from the National Inpatient Sample (NIS) Database. Peri-operative factors associated with delirium were screened and underwent statistical analysis to identify independent predictors for delirium following hepatic resection.ResultsA total of 80,070 patients underwent hepatic resection over a five-year period from 2015 to 2019. The overall occurrence of POD after hepatic resection was 1.46% (1039 cases), with a slight upward trend every year. The incidence of elective admission was 6.66% lower (88.60% vs. 81.94%) than that of patients without POD after hepatic resection and 2.34% (45.53% vs. 43.19%) higher than that of patients without POD in teaching hospitals (P < 0.001). In addition, POD patients were 6 years older (67 vs. 61 years) and comprised 9.27% (56.69% vs. 47.42%) more male patients (P < 0.001) compared to the unaffected population. In addition, the occurrence of POD was associated with longer hospitalization duration (13 vs. 5 days; P < 0.001), higher total cost ($1,481,89 vs. $683,90; P < 0.001), and higher in-hospital mortality (12.61% vs. 4.11%; P < 0.001). Multivariate logistic regression identified hepatic resection-independent risk factors for POD, including non-elective hospital admission, teaching hospital, older age, male sex, depression, fluid and electrolyte disorders, coagulopathy, other neurological disorders, psychoses, and weight loss. In addition, the POD after hepatic resection has been associated with sepsis, dementia, urinary retention, gastrointestinal complications, acute renal failure, pneumonia, continuous invasive mechanical ventilation, blood transfusion, respiratory failure, and wound dehiscence / non-healing.ConclusionAlthough the occurrence of POD after hepatic resection is relatively low, it is beneficial to investigate factors predisposing to POD to allow optimal care management and improve the outcomes of this patient population.

Incidence and survival outcomes of patients with high-grade appendicular bone sarcoma and isolated regional lymph node metastasis: A national cohort database study

BackgroundWhile distant metastases in primary bone sarcomas have been extensively studied, the impact of isolated regional lymph node (LN) metastasis on survival remains unknown. In patients with primary bone sarcomas, we sought to assess the prevalence of isolated regional LN metastasis and the survival of this population. MethodsA total of 6651 patients with histologically-confirmed high-grade osteosarcoma, Ewing sarcoma, or chondrosarcoma were retrieved from the SEER database. We defined four subgroups for our analysis: localized disease (N0 M0), isolated regional LN metastasis (N1 M0), isolated distant metastasis (N0 M1), and combined regional LN and distant metastasis (N1 M1). Disease-specific survival (DSS) was assessed using the Kaplan-Meier method. ResultsPrevalence of isolated regional LN metastasis (N1 M0) was highest in Ewing sarcoma (27/1097; 3.3 %), followed by chondrosarcoma (18/1702; 1.4 %) and osteosarcoma (26/3740; 0.9 %). In all three histologies, patients with isolated regional LN metastasis had a worse 2-year, 5-year, and 10-year DSS than those with localized disease. Chondrosarcoma patients with isolated regional LN (N1 M0) metastasis had a significantly higher DSS in comparison to those with only distant metastasis (N0 M1) at the 5- and 10-year marks; for osteosarcoma and Ewing sarcoma, only a pattern towards higher survival was seen. Risk factors for presenting isolated regional LN metastasis included tumor location in lower-limb (OR = 2.01) or pelvis (OR = 2.49), diagnosis of Ewing sarcoma (OR = 2.98), and tumor >10 cm (OR = 1.96). ConclusionsIsolated regional LN metastases in primary bone sarcomas is an infrequent presentation associated with worse survival than localized disease. Level of evidenceIII.

Safety of redo sleeve gastrectomy as a primary revisional procedure

BackgroundInsufficient weight loss after primary laparoscopic sleeve gastrectomy (LSG) occasionally requires revisional surgery. A few single-institution studies have examined the safety of redo LSG (RSG) and have shown mixed results. ObjectivesThe aim of this study was to evaluate the safety of RSG compared with LSG over a period of 30 days. SettingUniversity of Southern California, United States; Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. MethodsThe 2020–2021 MBSAQIP registry was used to evaluate patients who underwent RSG. Thirty-day outcomes were evaluated using univariable analysis and multivariable logistic and linear regression. ResultsA total of 226,029 patients were reviewed, of whom 1454 (.7%) underwent RSG and 224,575 (99.3%) underwent initial LSG. Patients who underwent RSG were older (45 versus 42 yr), predominantly female (86.2% versus 81.3%), had a lower body mass index (40.0 versus 43.4), fewer co-morbidities, and greater rates of gastroesophageal reflux (38.7% versus 25.1%). They demonstrated increased overall complications (3.6% versus 2.1%, P < .001) and a longer operative time (81 versus 62 min, P < .001), but there was no difference in mortality. On multivariable analysis, patients who underwent RSG were independently associated with an increased risk of overall postoperative complications (odds ratio [OR]: 1.493, P = .018), organ space infection (OR: 6.231, P < .001), staple line leak (OR: 12.838, P < .001), pneumonia (OR: 3.85, P = .013), ventilator requirement over 48 hours (OR: 6.404, P = .035), sepsis (OR: 4.397, P = .010), septic shock (OR: 8.669, P < .001), reoperation (OR: 1.808, P = .013), readmission (OR: 2.104, P < .001), reintervention (OR: 4.435, P < .001), and longer operative times (β = 12.790, P < .001). ConclusionsIn this national database study, RSG was associated with increased rates of postoperative complications and a longer operative time. Although these results are concerning, further studies are required to examine long-term outcomes.

The burden and predictors of 30-day unplanned readmission in patients with acute liver failure: a national representative database study

BackgroundLiver diseases were significant source of early readmission burden. This study aimed to evaluate the 30-day unplanned readmission rates, causes of readmissions, readmission costs, and predictors of readmission in patients with acute liver failure (ALF).MethodsPatients admitted for ALF from 2019 National Readmission Database were enrolled. Weighted multivariable logistic regression models were applied and based on Directed Acyclic Graphs. Incidence, causes, cost, and predictors of 30-day unplanned readmissions were identified.ResultsA total of 3,281 patients with ALF were enrolled, of whom 600 (18.3%) were readmitted within 30 days. The mean time from discharge to early readmission was 12.6 days. The average hospital cost and charge of readmission were $19,629 and $86,228, respectively. The readmissions were mainly due to liver-related events (26.6%), followed by infection (20.9%). The predictive factors independently associated with readmissions were age, male sex (OR 1.227, 95% CI 1.023–1.472; P = 0.028), renal failure (OR 1.401, 95% CI 1.139–1.723; P = 0.001), diabetes with chronic complications (OR 1.327, 95% CI 1.053–1.672; P = 0.017), complicated hypertension (OR 1.436, 95% CI 1.111–1.857; P = 0.006), peritoneal drainage (OR 1.600, 95% CI 1.092–2.345; P = 0.016), etc.ConclusionsPatients with ALF are at relatively high risk of early readmission, which imposes a heavy medical and economic burden on society. We need to increase the emphasis placed on early readmission of patients with ALF and establish clinical strategies for their management.

Factors Associated with Self-Reported Voice Change in the Hospitalized Burn Population: A Burn Model System National Database Study.

Voice plays a prominent role in verbal communication and social interactions. Acute burn care often includes intubation, mechanical ventilation, and tracheostomy, which could potentially impact voice quality. However, the issue of long-term dysphonia remains underexplored. This study investigates long-term self-reported voice changes in individuals with burn injuries, focusing on the impact of acute burn care interventions. Analyzing data from a multicenter longitudinal database (2015-2023), self-reported vocal changes were examined at discharge and 6, 12, 24, and 60 months after injury. Out of 582 participants, 65 reported voice changes at 12 months. Changes were prevalent at discharge (16.4%) and persisted over 60 months (11.6-12.7%). Factors associated with voice changes included flame burn, inhalation injury, tracheostomy, outpatient speech-language pathology, head/neck burn, larger burn size, mechanical ventilation, and more ventilator days (p < 0.001). For those on a ventilator more than 21 days, 48.7% experience voice changes at 12 months and 83.3% had received a tracheostomy. The regression analysis demonstrates that individuals that were placed on a ventilator and received a tracheostomy were more likely to report a voice change at 12 months. This study emphasizes the need to understand the long-term voice effects of intubation and tracheostomy in burn care.

Biceps tenotomy vs. tenodesis: an ACS-NSQIP analysis of postoperative outcomes and utilization trends

BackgroundWhile studies have assessed comparative rates of restoration of shoulder function and alleviation of symptoms, comparative systemic postoperative complication rates between biceps tenotomy and tenodesis have yet to be assessed. The purpose of the present study was to use a national administrative database to perform a comprehensive investigation into 30-day complication rates after biceps tenotomy versus tenodesis, thus providing valuable insights for informed decision-making by clinicians and patients regarding the optimal surgical approach for pathologies of the long head of the biceps tendon. MethodsThe National Surgical Quality Improvement Program (NSQIP) database was queried to analyze postoperative complication rates and metrics associated with biceps tenotomy and tenodesis. Patient data spanning from 2012-2021 were extracted with relevant variables assessed to identify and compare these two surgical approaches. Adjusted and unadjusted analyses were utilized to analyze patient demographics, comorbidities, operative times, lengths of stay, readmissions, adverse events, and yearly surgical volume, along with trends in usage, across cohorts. ResultsOf 11,527 total patients, 264 (2.29%), 6,826 (59.22%), and 4,437 (38.49%) underwent tenotomy, tenodesis with open repair, and tenodesis with arthroscopic repair, respectively. Tenotomy operative times ([mean ± SD]: 66.25 ± 44.76 minutes) were shorter than those for open tenodesis (78.83 ± 41.82) and arthroscopic tenodesis (75.98 ± 40.16). Conversely, tenotomy patients had longer hospital (0.88 ± 4.86 days) relative to open tenodesis (.08 ± 1.55) and arthroscopic tenodesis (.12 ± 2.70). Multivariable logistic regression controlling for demographics and comorbidities demonstrated that patients undergoing tenodesis were less likely to be readmitted (adjusted odds ratio [AOR]: 0.42, 95% confidence interval [CI]: 0.17-0.98, P =0.050) or sustain serious adverse events (AOR: 0.27, 95% CI: 0.13-0.57, P <.001), but equally likely to sustain minor adverse events (AOR: 0.87, CI: 0.21-3.68, P =.850), compared with patients undergoing tenotomy. Lastly, comparing utilization rates from 2012 to 2021 revealed a significant decrease in the proportion of tenotomy (from 6.2% to 1.0%) compared to open tenodesis (from 41.0% to 57.3%) and arthroscopic tenodesis (52.8% to 41.64%; Ptrend = .001). ConclusionTo our knowledge, this is the first large national database study investigating postoperative complication rates between the various surgical treatments for pathologies of the long head of the biceps tendon. Our results suggest that tenodesis yields fewer serious adverse events and lower readmission rates than tenotomy. We also found a shorter operative time for tenotomy. These findings support the increased utilization of tenodesis relative to tenotomy in recent years.

Genomic Landscape and Clinical Features of Advanced Thyroid Carcinoma: A National Database Study in Japan.

The relationship between the genomic profile and prognosis of advanced thyroid carcinoma requiring drug therapy has not been reported. To evaluate the treatment period and overall survival time for each genetic alteration in advanced thyroid carcinoma that requires drug therapy. We conducted a retrospective observational study using a national database in Japan, which included 552 cases of thyroid carcinoma out of 53 543 patients in the database. The database included anaplastic thyroid carcinoma (23.6%), poorly differentiated thyroid carcinoma (10.0%), and differentiated thyroid carcinoma (66.4%). The most common genetic abnormalities were TERT promoter (66.3%), BRAF (56.7%), and TP53 (32.2%). The typical driver genes were BRAF V600E (55.0%), RAS (18.5%), RET fusion (4.7%), NTRK fusion (1.6%), and ALK fusion (0.4%). The most common regimen was lenvatinib, and the time to treatment failure was not different despite the presence of BRAF or RAS mutations. In differentiated thyroid carcinoma and poorly differentiated thyroid carcinoma, TP53 alterations independently predicted worse overall survival (hazard ratio = 2.205, 95% confidence interval: 1.135-4.283). In anaplastic thyroid carcinoma, no genetic alterations were associated with overall survival. Genetic abnormalities with treatment options were found in 62.7% of advanced thyroid carcinomas. TP53 abnormality was an independent poor prognostic factor for overall survival in differentiated thyroid carcinoma. The time to treatment failure for lenvatinib was not different based on genetic profile.

565 Pediatric Patients with Post-Burn Amputations Report Worse Long-Term Physical Function but Not Self Appearance

Abstract Introduction Amputation after burn injury may improve survival rates; however, the physical changes and functional impairments resulting from amputation can have long-term consequences. A prior Burn Model System (BMS) national database study found that post-burn amputation among adults was negatively correlated with mental health scores but positively correlated with physical function scores at 6-months post-burn. However, no study has examined long-term outcomes associated with post-burn amputation in the pediatric population. This study investigates longitudinal functional and psychosocial outcomes among pediatric burn patients with amputations. Methods Pediatric participants (8 – 17 years old) enrolled in the BMS database between 2015 – 2023 with post-burn amputations were included. Participants with amputations were matched using nearest-neighbor matching to those without, based on burn location, age and % total burn surface area. Primary outcomes were the PROMIS-25 v2.0 Physical Function and the Child Burn Outcomes Questionnaire: appearance sub-score, measured at 6-, 12- and 24-months post-burn. In addition to cross-sectional pairwise analyses at each time-point, linear mixed effects models were used to assess differences in outcomes between those with and those without amputations after adjusting for time while accounting for repeated measures. Additional linear mixed effects models, including an interaction between amputation status and time, were conducted to assess whether the change in outcome scores across time differed between those with and without amputations. A two-sided significance level of 0.05 was used to determine statistical significance. Results In this study, 17 participants had amputations and 17 did not. A total of 7 participants had upper amputation only, 1 had lower amputation only, 2 had upper and lower amputation and 7 were unknown. Amputation was significantly associated with lower physical function scores (9.3 points lower, p=0.006) after adjusting for follow-up time-points. However, there was no evidence that the difference in physical function scores worsened or improved over time. Pairwise analyses at each time-point found those with amputations reported significantly lower physical function scores at 24-months post-burn (54.9 ±11.6 vs. 66 ±5, p=0.013). No significant differences were found in appearance scores or in the change in appearance scores. Conclusions Amputation was significantly associated with worse physical function scores. Participants with amputation fared as well in appearance scores as those without amputation. Pediatric burn patients with amputations might benefit from tailored amputee-specific rehabilitation services, amputee peer support, and school reentry programs. Applicability of Research to Practice This study can be used to guide recommendations for physical/occupational therapy and other rehabilitative services available to pediatric burn patients with amputations.

Association Between Burn Location and Psychological Distress: A Burn Model System National Database Study.

Burn injuries often lead to psychological distress, from depression and anxiety to adjustment concerns and posttraumatic stress. There is some evidence that the anatomical location of burn injuries (eg, head/neck, feet) has a specific negative effect on psychological functioning. The purpose of this study was to examine the associations between burn injury location and emotional distress. First, we administered self-report questionnaires to burn survivors with ≤ 5% TBSA at a single adult outpatient burn clinic. Second, we used a cross-sectional analysis of the Burn Model System National Database. The mean values of each measure of psychological distress (ie, quality of life, self-esteem, depression, posttraumatic stress, anxiety, and, for contrast, posttraumatic growth) were examined for each anatomical location for those participants with a burn in those anatomical areas against those with burn in other areas. Using Kruskal-Wallis tests to compare psychological distress, we found no significant differences in outcome measures in either sample analyzed in our study. These findings contrast with prior literature indicating the negative psychological effect of burn injuries on certain locations in the body. Further research should explore whether larger burns (ie, < 5% TBSA) affecting critical areas of the body may be associated with psychological distress.

Associations of urban versus rural patient residence on outcomes after burn: A national inpatient sample database study

IntroductionBurn patients in rural areas may encounter poorer outcomes associated with barriers to care; however, residence has not been studied in a large sample. The association between rural-versus-urban residence and outcomes after burn was examined using the National Inpatient Sample (NIS) database. MethodsUsing the 2019 NIS database, patients over 18 years with a primary diagnosis of burn or corrosive injury were included. Level of urbanization was categorized into six groups. Outcomes after burn such as in-hospital mortality, multifactorial shock, prolonged mechanical ventilation, length of stay, and total costs were analyzed after adjusting for demographic factors and hospital characteristics. ResultsWe included 4671 records, which represented a weighted population of 23,085 patients. Rural residence was associated with higher percentage of prior transfer but not in-hospital mortality. Compared to the most urbanized counties, encounters from the most rural counties were associated with higher odds of shock (aOR:2.62, 99% CI: 1.04–6.56, p = 0.007). ConclusionBurn encounters from less urbanized counties did not experience differences in mortality, rates of skin grafting, prolonged mechanical ventilation, length of stay, or overall costs. However, odds of shock were higher among the least urbanized counties. Despite improved triage and transportation systems across the US, disparities and challenges exist for burn patients from rural residence.

Mental health in persons with von Willebrand disease in the United States – a large national database study

BackgroundThere are very few large population-based studies studying mental health in persons with von Willebrand disease (PwVWD). ObjectivesWe aim to assess prevalence of depression and anxiety in PwVWD over a period of 20 years and identify bleeding symptoms that may be more likely associated with depression and anxiety in PwVWD. MethodsThis is a retrospective cohort study using a deidentified national dataset from 1118 hospitals with 176 million patients. Cases were defined as patients aged 0-110 years, both male and female, with von Willebrand disease (VWD), without hemophilia. Controls were defined as patients aged 0-110 years, both male and female, without VWD or hemophilia. We compared rates of depression and anxiety in cases and controls and by type of bleeding symptoms. ResultsWe identified 66 367 PwVWD and 183 890 766 controls. The prevalence of depression (23.12% vs 8.62%; p ≤ .00093; relative risk = 2.68) and anxiety (32.90% vs 12.29%; p ≤ .00093; relative risk = 2.68) was higher in PwVWD. Most of the bleeding symptoms were associated with higher rates of depression and anxiety in PwVWD with the highest rates with abnormal uterine bleeding, hematemesis, hemoptysis, hematuria, and melena. ConclusionOur study shows that mental health disorders in PwVWD are a significant health burden, and that burden is increased with documented bleeding symptoms. It is important that primary care physicians and hematologists caring for this population recognize this increased risk and appropriately screen and refer to mental health professionals.

Risk Factors for Unexpected Admission Following Lumbar Spine Laminectomy: A National Database Study.

Introduction Laminectomy is one of the most common orthopedic spine surgeries performed in the United States. Compared to other spine operations such as fusions, laminectomies in isolation are of lower morbidity. However, complications may arise that result in readmission to an inpatient healthcare facility.The purpose of this study is to identify the demographics and risk factors associated with unplanned 30-day readmission following a laminectomy. Methods The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for patients who underwent a laminectomy procedure from 2015 to 2019 using CPT code 63030. This query yielded 61,708 cases. Demographic, lifestyle, comorbidity, and peri-operative factors were recorded. Independent samples Student's t-tests, chi-squared, and, where appropriate, Fisher's exact tests were used in univariate analyses to identify demographic, lifestyle, and peri-operative variables related to 30-day readmission following a laminectomy procedure. Multivariate logistic regression modeling was subsequently performed. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated and reported. Results Of the 61,708 patients included in our sample, 2,359 were readmitted within 30 days of surgery, corresponding to a readmission rate of 3.82%. Results of the univariate analysis revealed statistically significant relationships between readmission status and the following patient variables: patient age, sex, BMI, ASA classification, race, bleeding disorder, chronic obstructive pulmonary disease (COPD), diabetes, hypertension, congestive heart failure (CHF), chronic steroid use, total operative time, and tobacco use (p < 0.05). Multivariate logistic regression modeling confirmed that the following patient variables were associated with statistically significantly increased odds of readmission: age greater than 65 (p < 0.05), female sex (p = 0.013), bleeding disorder (p = 0.011), diabetes (p = 0.006), current smoker (p = 0.010), COPD (p < 0.001), steroid use (p = 0.006), ASA Class II or above (p < 0.05), and total operative time (p < 0.001). Conclusion Unplanned 30-day readmission after laminectomy is infrequent. However, increasing age, female sex, steroid use, current smokers, bleeding disorders, diabetes, COPD, CHF, a higher ASA classification, and longer operative times are independent risk factors for readmission following laminectomy.

Chronic Use of Prescription Pain Medication and Outcomes in Patients With Burn Injury: A Burn Model System National Database Study.

This study attempts to examine long-term pain medication usage after burn injury and its association with functional and psychosocial outcomes. This is a multicenter retrospective cohort study utilizing the Burn Model System National Longitudinal Database. Participants injured from 2015 to 2021 were divided into two groups, those taking and not taking prescription pain medication at 12 mos after injury. Regression analyses examined associations between pain medication use and outcomes at 12 mos, adjusting for demographics, burn size, length of hospital stay, and preinjury pain medication use and employment status. Outcomes included VR-12 Physical and Mental Component Summary scores Patient-Reported Outcomes Measurement Information System Anxiety and Depression scores, Satisfaction with Life Scale, and employment status. Of 358 participants analyzed, prescription pain medication use was associated with worse outcomes at 12 mos: Physical Component Summary (β = -7.11, P < 0.001), Mental Component Summary (β = -6.01, P < 0.001), and Patient-Reported Outcomes Measurement Information System Depression (β = 4.88, P < 0.001) and Anxiety (β = 6.16, P < 0.001). Satisfaction with Life Scale was not significantly associated with pain medication use ( P = 0.069) and those taking pain medication were 52% less likely to be employed at 12 mos ( P = 0.035). There is a significant association between prescription pain medication use and worse physical, mental, and employment outcomes at 12 mos after burn injury.

Short term safety of magnetic sphincter augmentation vs minimally invasive fundoplication: an ACS-NSQIP analysis

PurposeMagnetic Sphincter Augmentation (MSA) is an FDA-approved anti-reflux procedure with comparable outcomes to fundoplication. However, most data regarding its use are limited to single or small multicenter studies which may limit the generalizability of its efficacy. The purpose of this study is to evaluate the outcomes of patients undergoing MSA vs fundoplication in a national database.Materials and MethodsThe 2017–2020 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Registry was utilized to evaluate patients undergoing MSA or fundoplication. Patients requiring Collis gastroplasty, paraesophageal hernia repair, and emergency cases, were excluded. Patient outcomes included overall complication rates, readmissions, reoperations, and mortality.ResultsA total of 7,882 patients underwent MSA (n = 597) or fundoplication (n = 7285). MSA patients were younger (51 vs 57, p < 0.001), and more often male (49.6 vs 34.3%, p < 0.001). While patients undergoing MSA experienced similar rates of reoperation (1.0 vs 2.0%, p = 0.095), they experienced fewer readmissions (2.2 vs 4.7%, p = 0.005), complications (0.6 vs 4.0%, p < 0.001), shorter mean (SD) hospital length of stay(days) (0.4 ± 4.3 vs 1.8 ± 4.6, p < 0.001) and operative time(min) (80.8 ± 36.1 vs 118.7 ± 63.7, p < 0.001). Mortality was similar between groups (0 vs 0.3%, p = 0.175). On multivariable analysis, MSA was independently associated with reduced postoperative complications (OR 0.23, CI 0.08 to 0.61, p = 0.002), readmissions (OR 0.53, CI 0.30 to 0.94, p = 0.02), operative time (RC − 36.56, CI − 41.62 to − 31.49. p < 0.001) and length of stay (RC − 1.22, CI − 1.61 to − 0.84 p < 0.001).ConclusionIn this national database study, compared to fundoplication MSA was associated with reduced postoperative complications, fewer readmissions, and shorter operative time and hospital length of stay. While randomized trials are lacking between MSA and fundoplication, both institutional and national database studies continue to support the use of MSA as a safe anti-reflux operation.

Quality of life and neurological symptoms in patients with neurofibromatosis type 2: a national database study in Japan.

This study examined the association between neurological symptoms and quality of life (QoL) in patients with neurofibromatosis type 2 (NF2) using a national database of all patients who newly claimed for medical expense subsidies in Japan from 2015 to 2019. The Japanese Ministry of Health, Labour and Welfare provided access to the "National Database of Designated Intractable Diseases of Japan" containing the "Medical Certificates of Designated Intractable Diseases" of all patients with NF2. The database included information on five items of QoL: "mobility," "self-care," "usual activities," "pain/discomfort," and "anxiety/depression." To examine the association between the presence/absence of neurological symptoms and QoL, multivariable logistic regression analyses were performed, adjusted for potential confounders. Data from 187 patients (97 females and 90 males; mean (standard deviation) age, 43.1 (17.9) years) were analyzed. Overall, 31% to 55% of patients were recorded as having moderate/severe impairment of QoL. Spinal dysfunction was significantly associated with deterioration of all components of QoL, whereas speech dysfunction and hemiparesis were specifically associated with physical health-related components of QoL. Spinal dysfunction, facial nerve palsy, and age 25-64 years were significantly associated with "anxiety/depression." In the present epidemiological study using a national database of NF2 in Japan, spinal dysfunction was significantly associated with deterioration of all components of QoL, including subjective and mental health-related components of QoL, whereas speech dysfunction and hemiparesis were specifically associated with physical health-related components of QoL.

Adverse Events After Isolated Posterior Cruciate Ligament Reconstruction: A National Database Study.

Optimal management after posterior cruciate ligament (PCL) injury remains an active area of research, as reconstruction is technically challenging and poses unique risks in the posterior knee. Studies have reported variable rates of complications. To describe the rates of readmission, emergency department (ED) visits, and postoperative complications within 90 days of isolated PCL reconstruction (PCLR) in a large, national cohort to better understand the perioperative variables that influence a practitioner's decision of whether to pursue operative versus nonoperative management. Descriptive epidemiology study. PCLRs from January 1, 2010, through August 31, 2020, were identified in PearlDiver, a national administrative database. Patients with concomitant ligament surgery and those with fewer than 90 days of postoperative database activity were excluded. Deep vein thromboses, pulmonary embolisms, surgical site infections, compartment syndrome, and vascular events within 90 days of surgery were identified, as were 90-day readmissions and ED visits. Logistic regression models were built in PearlDiver to calculate odds ratios (ORs) for ED utilization. The final cohort consisted of 1154 patients with isolated PCLR (mean age, 34 ± 16 years; 62% male). Most patients were located in the Southern United States (n = 417; 36.1%), and most had commercial insurance (n = 992; 86%). The 90-day rates of adverse events were as follows: deep vein thrombosis (13; 1.1%), pulmonary embolism (19; 1.6%), surgical site infection (<11; <1%), compartment syndrome (<11; <1%), vascular event (<11; <1%), readmission (13, 1.1%), and ED utilization (99; 8.6%). The majority of emergency department visits (52%) occurred in the first 2 weeks postoperatively. Predictive factors for ED utilization included Elixhauser Comorbidity Index score (OR = 1.31 per 2-point increase) and Medicaid insurance (OR = 2.03 relative to commercial insurance). The current study reported rates of adverse events after isolated PCLR in a large, national cohort. The results provide important context for decisions about optimal management of PCL injury.
