The Society of Thoracic Surgeons Database Analysis: Comparing Sublobar Techniques in Stage IA Lung Cancer.

BACKGROUND: This study compares sublobar resections-wedge resection and segmentectomy-in clinical stage IA lung cancers. It tests the hypothesis that overall survival after wedge resection is similar to segmentectomy. METHODS: Adults undergoing wedge resection or segmentectomy for clinical stage IA lung cancer were identified from The Society of Thoracic Surgeons General Thoracic Surgery Database. Eligible patients were linked to the Centers for Medicare and Medicaid Services database using a matching algorithm. The primary outcome was long-term overall survival. Propensity scores overlap weighting (PSOW) adjustment of wedge resection using validated covariates was used for group difference mitigation. Kaplan-Meier and Cox regression models analyzed survival. All-cause first readmission, and morbidity and mortality were examined using PSOW regression models. RESULTS: Of 9756 patients, 6141 met inclusion criteria, comprising 2154 segmentectomies and 3987 wedge resections. PSOW reduced differences between the groups. Unadjusted perioperative mortality was comparable, but wedge resection showed lower major morbidity rates. Weighted regression analysis indicated reduced mortality and major morbidity risks in wedge resection. Kaplan-Meier analysis revealed no mortality difference between groups, which was confirmed by PSOW Cox regression models. The cumulative risk of readmission was also comparable for both groups, with Cox Fine-Gray models showing no difference in rehospitalization risks. CONCLUSIONS: In clinical stage IA lung cancer, relative to segmentectomy, wedge resection has comparable overall survival and lower perioperative morbidity, suggesting it is an equally effective option for the broader population of patients with clinical stage IA lung cancer, not only those at highest risk of complications.

Comparison of Transcatheter Edge-to-Edge Mitral Valve Repair for Primary Mitral Regurgitation Outcomes to Hospital Volumes of Surgical Mitral Valve Repair.

BACKGROUND: Transcatheter edge-to-edge mitral valve (MV) repair (TEER) is an effective treatment for patients with primary mitral regurgitation at prohibitive risk for surgical MV repair (MVr). High-volume MVr centers and high-volume TEER centers have better outcomes than low-volume centers, respectively. However, whether MVr volume predicts TEER outcomes remains unknown. We hypothesized that high-volume MV surgical centers would have superior risk-adjusted outcomes for TEER than low-volume centers. METHODS: We combined data from the American College of Cardiology/Society of Thoracic Surgeons Transcatheter Valve Therapy registry and the Society of Thoracic Surgeons adult cardiac surgery database. MVr was defined as leaflet resection or artificial chords with or without annuloplasty and was evaluated as a continuous variable and as predefined categories (<25, 25-49, and ≥50 MV repairs/year). A generalized linear mixed model was used to evaluate risk-adjusted in-hospital/30-day mortality, 30-day heart failure readmission, and TEER success (mitral regurgitation ≤2+ and gradient <5 mm Hg). RESULTS: The study comprised 41 834 patients from 500 sites of which 332 (66.4%) were low, 102 (20.4%) intermediate, and 66 (13.2%) high-volume surgical centers (P<0.001). TEER success was 54.6% and was not statistically significantly different across MV surgical site volumes (P=0.4271). TEER mortality at 30 days was 3.5% with no significant difference across MVr volume on unadjusted (P=0.141) or adjusted (P=0.071) analysis of volume as a continuous variable. One-year mortality was 15.0% and was lower for higher MVr volume centers when adjusted for clinical and demographic variables (P=0.027). Heart failure readmission at 1 year was 9.4% and was statistically significantly lower in high-volume centers on both unadjusted (P=0.017) or adjusted (P=0.015) analysis. CONCLUSIONS: TEER can be safely performed in centers with low volumes of MV repair. However, 1-year mortality and heart failure readmission are superior at centers with higher MVr volume.

National Variation in Hospital MTEER Outcomes and Correlation With TAVR Outcomes: STS/ACC TVT Registry Analysis.

BACKGROUND: A single, multitiered valve center designation has been proposed to publicly identify centers with expertise for all valve therapies. The correlation between transcatheter aortic valve replacement (TAVR) and mitral transcatheter edge-to-edge repair (MTEER) procedures is unknown. OBJECTIVES: The authors sought to examine the relationship between site-level volumes and outcomes for TAVR and MTEER. We further explored variability between sites for MTEER outcomes. METHODS: Using the STS/ACC TVT (Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy) national registry, TAVR and MTEER procedures at sites offering both therapies from 2013 to 2022 were examined. Sites were ranked into deciles of adjusted in-hospital and 30-day outcomes separately for TAVR and MTEER and compared. Stepwise, hierarchical multivariable models were constructed for MTEER outcomes, and the median OR was calculated. RESULTS: Between 2013 and 2022, 384,394 TAVRs and 53,274 MTEERs (median annualized volumes: 93.6 and 18.8, respectively) were performed across 453 U.S. sites. Annualized TAVR and MTEER volumes were moderately correlated (r = 0.48; P < 0.001). After adjustment, 14.3% of sites had the same decile rank for TAVR and MTEER 30-day composite outcome, 50.6% were within 2 decile ranks; 35% had more discordant outcomes for the 2 procedures (P = 0.0005). For MTEER procedures, the median OR for the 30-day composite outcome was 1.57 (95% CI: 1.51-1.64), indicating a 57% variability in outcome by site. CONCLUSIONS: There is modest correlation between hospital-level volumes for TAVR and MTEER but low interprocedural correlation of outcomes. For similar patients, site-level variability for mortality/morbidity following MTEER was high. Factors influencing outcomes and "centers of excellence" as a whole may differ for TAVR and MTEER.

Interventions to Improve Long-Term Adherence to Physical Rehabilitation: A Systematic Review.

OBJECTIVE: To evaluate the impact of physical rehabilitation interventions, supplemented with one or more adherence-enhancing components, on outcomes among adults with hip or knee osteoarthritis or chronic lower back pain. DESIGN: Primary literature search from inception of each database to July 27, 2021, guided by relevant search terms and keywords to search titles and abstracts. All articles meeting eligibility criteria were included for data abstraction. DATA SOURCES: MEDLINE, CINAHL Complete, and Embase. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomized and nonrandomized trials evaluating adherence-focused intervention components conducted in addition to an index usual care or usual care-like physical rehabilitation program among adults with hip or knee osteoarthritis or chronic low back pain. Eligible studies included a comparator group of the same index physical rehabilitation intervention without the adjunctive adherence components. Included studies measured outcomes at least 3 months after the rehabilitation course. RESULTS: Of the 10 studies meeting inclusion criteria, 6 interventions were delivered concurrent to an index rehabilitation program and 4 were delivered sequentially. Of the 3 studies that reported a positive effect on long-term adherence, only 1 was a low risk of bias study. There is very limited evidence of a beneficial treatment effect of adjunct adherence interventions on long-term physical function, self-efficacy, or adverse events. CONCLUSION: We found inadequate evidence evaluating adherence-enhancing interventions for the specific promotion of long-term adherence to home rehabilitation programs. Future studies should consider testing interventions specifically built to target behavioral maintenance of home rehabilitation programs.

Transcatheter Edge-to-Edge Repair in COAPT-Ineligible Patients With Functional Mitral Regurgitation.

BACKGROUND: Mitral valve transcatheter edge-to-edge repair (MTEER) was approved in the United States for treatment of functional mitral regurgitation (FMR) based on results from the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial. OBJECTIVES: The authors sought to analyze outcomes of MTEER in FMR patients who would have been excluded from COAPT. METHODS: MTEER procedures performed for FMR in the TVT (Transcatheter Valve Therapy) Registry between January 1, 2013, and April 30, 2020, were categorized as "trial-ineligible" if any of the following were present: cardiogenic shock, inotropic support, left ventricular ejection fraction <20%, left ventricular end-systolic dimension >7 cm, home oxygen use, or severe tricuspid regurgitation. Trial-ineligible and trial-eligible groups were compared through 1 year using multivariable models. The primary endpoint was 1-year death or heart failure hospitalization (HFH). RESULTS: Of 6,675 patients who underwent MTEER for FMR, 3,721 (55.7%) were trial-eligible and 2,954 (44.3%) were trial-ineligible. Trial-ineligible patients had lower rates of technical procedural success (86.9% vs 92.6%; P < 0.001) and more frequent in-hospital complications (11.8% vs 5.7%; P < 0.001) compared with trial-eligible patients. A clinically meaningful improvement in health status at 30 days was observed in 78.9% and 77.0% of patients in the trial-ineligible and trial-eligible groups, respectively. There was a higher risk of 1-year death or HFH (HR: 1.73; 95% CI: 1.57-1.91; P < 0.001) in trial-ineligible patients. CONCLUSIONS: Among patients who underwent MTEER for FMR in the TVT Registry, nearly one-half would have been ineligible for the COAPT trial. Health status improvement at 30 days was similar in COAPT-ineligible and COAPT-eligible patients, but trial-ineligible patients had higher 1-year rates of death or HFH.

Genomic classifiers and prognosis of localized prostate cancer: a systematic review.

BACKGROUND: Refinement of the risk classification for localized prostate cancer is warranted to aid in clinical decision making. A systematic analysis was undertaken to evaluate the prognostic ability of three genomic classifiers, Decipher, GPS, and Prolaris, for biochemical recurrence, development of metastases and prostate cancer-specific mortality in patients with localized prostate cancer. METHODS: Data sources: MEDLINE, Embase, and Web of Science were queried for reports published from January 2010 to April 2022. STUDY SELECTION: prospective or retrospective studies reporting prognosis for patients with localized prostate cancer. DATA EXTRACTION: relevant data were extracted into a customized database by one researcher with a second overreading. Risk of bias was assessed using a validated tool for prognostic studies, Quality in Prognosis Studies (QUIPS). Disagreements were resolved by consensus or by input from a third reviewer. We assessed the certainty of evidence by GRADE incorporating adaptation for prognostic studies. RESULTS: Data synthesis: a total of 39 studies (37 retrospective) involving over 10,000 patients were identified. Twenty-two assessed Decipher, 5 GPS, and 14 Prolaris. Thirty-four studies included patients who underwent prostatectomy. Based on very low to low certainty of evidence, each of the three genomic classifiers modestly improved upon the prognostic ability for biochemical recurrence, development of metastases, and prostate cancer-specific mortality compared to standard clinical risk-classification schemes. LIMITATIONS: downgrading of confidence in the evidence stemmed largely from bias due to the retrospective nature of the studies, heterogeneity in treatment received, and era in which patients were treated (i.e., prior to the 2000s). CONCLUSIONS: Genomic classifiers provide a small but consistent improvement upon the prognostic ability of clinical classification schemes, which may be helpful when treatment decisions are uncertain. However, evidence from current management-era data and of the predictive ability of these tests is needed.

Characterizing Acute Low Back Pain in a Community-Based Cohort.

Acute low back pain (LBP) is a common experience, however, the associated pain severity, pain frequency, and characteristics of individuals with acute LBP in community settings have yet to be well understood. In this manuscript, three acute LBP severity categorization definitions were used based on LBP frequency combined with either 1) pain impact frequency (impact-based) or 2) pain intensity (intensity-based), as well as LBP pain interference frequency (interference only-based) severity categories. The purpose of this manuscript is to describe and then compare these acute LBP severity groups in the following characteristics: 1) sociodemographic, 2) general and physical health, and 3) psychological. This cross-sectional study used baseline data from 131 community-based participants with acute LBP (<4 weeks duration before screening and ≥30 pain-free days before acute LBP onset). Descriptive associations were calculated as prevalence ratios for categorical variables and Hedges' g for continuous variables. Our analyses identified several large associations for impact-based and intensity-based categories with global mental health, global physical health, STarT Back Screening Tool risk category, and general health. Larger associations were found with social constructs (racially and ethnically minoritized, performance of social roles, and isolation) when using the intensity-based versus impact-based categorization. The interference-based category did not capture as much variability between acute LBP severity categories. This study adds to the literature by providing standard ways to characterize community-based individuals experiencing acute LBP. The robust differences observed between these categorization approaches suggest that how we define acute LBP severity is consequential; these different approaches may be used to improve the early identification of factors potentially contributing to the development of chronic LBP.

Seventeen-Year National Pain Prevalence Trends Among U.S. Military Veterans.

U.S. military veterans experience higher pain prevalence than nonveterans. However, it is unclear how the disparities in pain prevalence have changed over time because previous trend studies are limited to veterans using the Veterans Health Administration. This repeated cross-sectional study aimed to characterize pain prevalence trends in the overall population of U.S. veterans compared to nonveterans, using nationally representative data. We analyzed 17 years of data from the National Health Interview Survey (2002-2018), with a mean annual unweighted sample of 29,802 U.S. adults (total unweighted n = 506,639) and mean annual weighted population of 229.7 million noninstitutionalized adults. The weighted proportion of veterans ranged from 11.48% in 2002 (highest) to 8.41% in 2017 (lowest). We found that veterans experience a similar or higher prevalence of pain than nonveterans across the study period, except for severe headaches or migraine and facial pain. Pain prevalence among veterans increased over time, with a higher rate of increase compared to nonveterans for all pain variables. From 2002 to 2018, there was an absolute increase (95% confidence interval) in pain prevalence among veterans (severe headache or migraine: 2.0% [1.6-2.4%]; facial pain: 1.9% [1.4-2.4%]; neck pain: 4.7% [4.1-5.2%]; joint pain: 11.4% [10.8-11.9%]; low back pain: 10.3% [9.5-11.1%]; any pain: 10.0% [9.6-10.4%]; and multiple pains: 9.9% [9.2-10.6%]). The continued pain prevalence increase among veterans may have implications for health care utilization, highlighting the need for improved pain prevention and care programs for this population with a disproportionate pain burden. PERSPECTIVE: This article uses routinely-collected cross-sectional data that are nationally representative of U.S. adults to present changes in pain prevalence among military veterans compared to nonveterans. The findings underscore the need for improved prevention and pain care programs for veterans, who experienced a widening disproportionate pain burden from 2002 to 2018.

Association Between Polyvascular Disease and Transcatheter Aortic Valve Replacement Outcomes: Insights From the STS/ACC TVT Registry.

BACKGROUND: Atherosclerotic cardiovascular disease is highly prevalent in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). Polyvascular disease (PVD), defined as involvement of ≥2 vascular beds (VBs), that is, coronary, cerebrovascular, or peripheral, portends a poor prognosis in patients with atherosclerotic cardiovascular disease; however, data on the association of PVD with outcomes of patients undergoing TAVR are limited. METHODS: The Society of Thoracic Surgeons and the American College of Cardiology Transcatheter Valve Therapy Registry was analyzed to identify patients who underwent TAVR from November 2011 to March 2022. The exposure of interest was PVD. The primary outcome was all-cause mortality. Secondary outcomes included major vascular complications, major/life-threatening bleeding, myocardial infarction, transient ischemic attack/stroke, and valve- and non-valve-related readmissions. Outcomes were assessed at 30 days and 1 year. RESULTS: Of 443 790 patients who underwent TAVR, PVD was present in 150 823 (34.0%; 111 425 [25.1%] with 2VB-PVD and 39 398 [8.9%] with 3VB-PVD). On multivariable analysis, PVD was associated with increased all-cause mortality at 1 year (hazard ratio, 1.17 [95% CI, 1.14-1.20]). There was an incremental increase in 1-year mortality with an increasing number of VBs involved (no PVD [reference]; 2VB-PVD: hazard ratio, 1.12 [95% CI, 1.09-1.15]: and 3VB-PVD: hazard ratio, 1.31 [95% CI, 1.26-1.36]). Patients with versus without PVD had higher rates of major vascular complications, major/life-threatening bleeding, transient ischemic attack/stroke, and non-valve-related readmissions at 30 days and 1 year. CONCLUSIONS: PVD is associated with worse outcomes after TAVR, and the risk is highest in patients with 3VB-PVD.

Outcomes of Transcatheter Aortic Valve Replacement in Asymptomatic or Minimally Symptomatic Aortic Stenosis.

BACKGROUND: Little is known about the outcomes of transcatheter aortic valve replacement (TAVR) in minimally symptomatic patients. OBJECTIVES: The authors aimed to evaluate the outcomes of patients with minimally symptomatic severe aortic stenosis treated with TAVR in the STS/ACC TVT registry. METHODS: Minimally symptomatic status was defined as a baseline Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ-OS) ≥75. Clinical and health status outcomes of TAVR in patients with severe aortic stenosis and normal left ventricular ejection fraction were compared between minimally symptomatic patients and those with moderate or severe symptoms. RESULTS: Among 231,285 patients who underwent TAVR between 2015 and 2021 (median age 80.0 years [IQR: 74.0-86.0 years], 47.5% female), 20.0% were minimally symptomatic before TAVR. Survival at 1 year was higher in minimally symptomatic patients vs those with moderate or severe symptoms (adjusted HR for death: 0.70 [95% CI: 0.66-0.75]). Mean KCCQ-OS increased by 2.7 points (95% CI: 2.6-2.9 points) at 30 days and 3.8 points (95% CI: 3.6-4.0 points) at 1 year in minimally symptomatic patients compared with increases of 32.2 points (95% CI: 32.0-32.3 points) at 30 days and 34.9 points (95% CI: 34.7-35.0 points) at 1 year in more symptomatic patients. Minimally symptomatic patients had higher odds of being alive and well at 1 year (OR: 1.19 [95% CI: 1.16-1.23]). CONCLUSIONS: Although minimally symptomatic patients treated with TAVR experience only small improvements in health status, their overall outcomes are favorable with a higher likelihood of survival with good health status at 1 year compared with more symptomatic patients.

The effects of a 6-month weight loss intervention on physical function and serum biomarkers in older adults with and without osteoarthritis.

Objective: To examine the effects of a 6-month weight loss intervention on physical function, inflammatory biomarkers, and metabolic biomarkers in both those with and without osteoarthritis (OA). Design: 59 individuals ≥60 years old with obesity and a functional impairment were enrolled into this IRB approved clinical trial and randomized into one of two 6-month weight loss arms: a higher protein hypocaloric diet or a standard protein hypocaloric diet. All participants were prescribed individualized 500-kcal daily-deficit diets, with a goal of 10% weight loss. Additionally, participants participated in three, low-intensity, exercise sessions per week. Physical function, serum biomarkers and body composition data were assessed at the baseline and 6-month timepoints. Statistical analyses assessed the relationships between biomarkers, physical function, body composition, and OA status as a result of the intervention. Results: No group effects of dietary intervention were detected on any outcome measures (multiple p â€‹> â€‹0.05). During the 6-month trial, participants lost 6.2 â€‹± â€‹4.0% of their bodyweight (p â€‹< â€‹0.0001) and experienced improved physical function on the Short-Performance-Physical-Battery (p â€‹< â€‹0.0001), 8-foot-up-and-go (p â€‹< â€‹0.0001), and time to complete 10-chair-stands (p â€‹< â€‹0.0001). Adiponectin concentrations (p â€‹= â€‹0.0480) were elevated, and cartilage oligomeric matrix protein (COMP) concentrations (p â€‹< â€‹0.0001) were reduced; further analysis revealed that reductions in serum COMP concentrations were greater in OA-negative individuals. Conclusions: These results suggest that weight loss in older adults with and without OA may provide a protective effect to cartilage and OA. In particular, OA-negative individuals may be able to mitigate changes associated with OA through weight loss.

Heart failure medical therapy prior to mitral transcatheter edge-to-edge repair: the STS/ACC Transcatheter Valve Therapy Registry.

BACKGROUND AND AIMS: Guideline-directed medical therapy (GDMT) is recommended before mitral valve transcatheter edge-to-edge repair (MTEER) in patients with heart failure (HF) and severe functional mitral regurgitation (FMR). Whether MTEER is being performed on the background of optimal GDMT in clinical practice is unknown. METHODS: Patients with left ventricular ejection fraction (LVEF) < 50% who underwent MTEER for FMR from 23 July 2019 to 31 March 2022 in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry were identified. Pre-procedure GDMT utilization was assessed. Cox proportional hazards models were constructed to evaluate associations between pre-MTEER therapy (no/single, double, or triple therapy) and risk of 1-year mortality or HF hospitalization (HFH). RESULTS: Among 4199 patients across 449 sites, beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, mineralocorticoid receptor antagonists, and angiotensin receptor-neprilysin inhibitors were used in 85.1%, 44.4%, 28.6%, and 19.9% before MTEER, respectively. Triple therapy was prescribed for 19.2%, double therapy for 38.2%, single therapy for 36.0%, and 6.5% were on no GDMT. Significant centre-level variation in the proportion of patients on pre-intervention triple therapy was observed (0%-61%; adjusted median odds ratio 1.48 [95% confidence interval (CI) 1.25-3.88]; P < .001). In patients eligible for 1-year follow-up (n = 2014; 341 sites), the composite rate of 1-year mortality or HFH was lowest in patients prescribed triple therapy (23.0%) compared with double (24.8%), single (35.7%), and no (41.1%) therapy (P < .01 comparing across groups). Associations persisted after accounting for relevant clinical characteristics, with lower risk in patients prescribed triple therapy [adjusted hazard ratio (aHR) 0.73, 95% CI .55-.97] and double therapy (aHR 0.69, 95% CI .56-.86) before MTEER compared with no/single therapy. CONCLUSIONS: Under one-fifth of patients with LVEF <50% who underwent MTEER for FMR in this US nationwide registry were prescribed comprehensive GDMT, with substantial variation across sites. Compared with no/single therapy, triple and double therapy before MTEER were independently associated with reduced risk of mortality or HFH 1 year after intervention.

Using Randomized Controlled Trials to Estimate the Effect of Community Interventions for Childhood Asthma.

INTRODUCTION: The Centers for Disease Control and Prevention's Controlling Childhood Asthma and Reducing Emergencies initiative aims to prevent 500,000 emergency department (ED) visits and hospitalizations within 5 years among children with asthma through implementation of evidence-based interventions and policies. Methods are needed for calculating the anticipated effects of planned asthma programs and the estimated effects of existing asthma programs. We describe and illustrate a method of using results from randomized control trials (RCTs) to estimate changes in rates of adverse asthma events (AAEs) that result from expanding access to asthma interventions. METHODS: We use counterfactual arguments to justify a formula for the expected number of AAEs prevented by a given intervention. This formula employs a current rate of AAEs, a measure of the increase in access to the intervention, and the rate ratio estimated in an RCT. RESULTS: We justified a formula for estimating the effect of expanding access to asthma interventions. For example, if 20% of patients with asthma in a community with 20,540 annual asthma-related ED visits were offered asthma self-management education, ED visits would decrease by an estimated 1,643; and annual hospitalizations would decrease from 2,639 to 617. CONCLUSION: Our method draws on the best available evidence from RCTs to estimate effects on rates of AAEs in the community of interest that result from expanding access to asthma interventions.

Mediators of Improvement in TAVR Outcomes Over Time: Insights From the STS-ACC TVT Registry.

BACKGROUND: Over the past decade, there has been substantial improvement in outcomes after transcatheter aortic valve replacement. Many patient and procedural factors have also changed over that time, making it challenging to untangle the drivers of those improvements. METHODS: Among patients who underwent transcatheter aortic valve replacement from 2012 to 2018 within the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapies Registry, we examined the relative contribution of changes in patient factors, device modifications, improving experience/skill, and advances in periprocedural care to the observed improvement in outcomes after transcatheter aortic valve replacement. Mediator clusters included demographics, noncardiovascular comorbidities, cardiovascular comorbidities, device-related factors, and nondevice-related procedural factors. Using logistic regression, we serially adjusted for the mediator clusters to examine the contribution of each to the observed improvement in outcomes over time. RESULTS: Among 161 196 patients treated with transcatheter aortic valve replacement at 596 sites, outcomes improved steadily from 2012 to 2018, including 30-day mortality (6.7% to 2.4%), 30-day composite adverse events (25.3% to 10.5%), and 1-year mortality (19.9% to 10.1%; all P<0.001). In sequential models, the unadjusted odds ratio for 30-day mortality was 0.82 per year (95% CI, 0.80-0.84), which was progressively attenuated with addition of each covariate cluster. Most of the improvement was explained by device factors and nondevice procedural factors. Results were similar for 30-day composite adverse events, although the observed temporal improvement was not fully explained by measured factors, suggesting improved technical skill as an additional mediator. In contrast to 30-day outcomes, each cluster of patient and procedural factors contributed similarly to the temporal improvement in 1-year mortality, indicating a greater impact of patient factors on longer-term outcomes. CONCLUSIONS: While US patients undergoing transcatheter aortic valve replacement have become younger, healthier, and lower risk over time, the most important factors contributing to improvements in short-term outcomes relate to advances in device technology and procedural factors, whereas changing patient characteristics had a greater impact on improvement in 1-year outcomes.

Facilitating Shared Decision Making Among Black Patients at Risk for Sudden Cardiac Arrest : A Randomized Clinical Trial.

BACKGROUND: Racial disparities in implantable cardioverter-defibrillator (ICD) implantation are multifactorial and are partly explained by higher refusal rates. OBJECTIVE: To assess the effectiveness of a video decision support tool for Black patients eligible for an ICD. DESIGN: Multicenter, randomized clinical trial conducted between September 2016 and April 2020. (ClinicalTrials.gov: NCT02819973). SETTING: Fourteen academic and community-based electrophysiology clinics in the United States. PARTICIPANTS: Black adults with heart failure who were eligible for a primary prevention ICD. INTERVENTION: An encounter-based video decision support tool or usual care. MEASUREMENTS: The primary outcome was the decision regarding ICD implantation. Additional outcomes included patient knowledge, decisional conflict, ICD implantation within 90 days, the effect of racial concordance on outcomes, and the time patients spent with clinicians. RESULTS: Of the 330 randomly assigned patients, 311 contributed data for the primary outcome. Among those randomly assigned to the video group, assent to ICD implantation was 58.6% compared with 59.4% in the usual care group (difference, -0.8 percentage point [95% CI, -13.2 to 11.1 percentage points]). Compared with usual care, participants in the video group had a higher mean knowledge score (difference, 0.7 [CI, 0.2 to 1.1]) and a similar decisional conflict score (difference, -2.6 [CI, -5.7 to 0.4]). The ICD implantation rate within 90 days was 65.7%, with no differences by intervention. Participants randomly assigned to the video group spent less time with their clinician than those in the usual care group (mean, 22.1 vs. 27.0 minutes; difference, -4.9 minutes [CI, -9.4 to -0.3 minutes]). Racial concordance between video and study participants did not affect study outcomes. LIMITATION: The Centers for Medicare & Medicaid Services implemented a requirement for shared decision making for ICD implantation during the study. CONCLUSION: A video-based decision support tool increased patient knowledge but did not increase assent to ICD implantation. PRIMARY FUNDING SOURCE: Patient-Centered Outcomes Research Institute.

Seventeen-Year National Pain Prevalence Trends Among U.S. Military Veterans.

Importance: U.S. military veterans experience higher pain prevalence and severity than nonveterans. However, it is unclear how these differences have changed over time. Previous studies are limited to veterans receiving care from the Veterans Health Administration. Objective: To characterize pain prevalence trends in the overall population of U.S. veterans compared to nonveterans, using nationally-representative data. Design: Repeated cross-sectional study. Data: National Health Interview Survey, 2002-2018. Analysis: January 2023. Setting: Population-based survey of noninstitutionalized U.S. adults. Participants: Across the 17-year period, mean annual weighted population was 229.7 million adults (unweighted sample total: n=506,639; unweighted sample annual mean: n=29,802). Exposure: Veteran status. Main Outcomes: Crude and demographics-adjusted pain prevalence trend differences between veterans and nonveterans across five pain variables (severe headache or migraine, facial pain, neck pain, low back pain, and joint pain) and two composite variables (any pain [≥1 prevalent pain] and multiple pains [≥2 prevalent pains]). Results: Weighted proportion of veterans varied from 11.48% in 2002 (highest) to 8.41% in 2017 (lowest). Across the study period, crude prevalence was generally similar or higher among veterans than nonveterans for all pain variables except for severe headache or migraine and facial pain. When equalizing age, sex, race, and ethnicity, pain prevalence among veterans remained similar or higher than nonveterans for all pain variables. From 2002 to 2018 there was an absolute increase (95% CI) in pain prevalence among veterans (severe headache or migraine: 2.0% [1.6% to 2.4%]; facial pain: 1.9% [1.4% to 2.4%]; neck pain: 4.7% [4.1% to 5.2%]; joint pain: 11.4% [10.8% to 11.9%]; low back pain: 10.3% [9.5% to 11.1%]; any pain: 10.0% [9.6% to 10.4%]; and multiple pains: 9.9% [9.2% to 10.6%]. Crude and adjusted analyses indicated prevalence of all pain variables increased more among veterans than nonveterans from 2002 to 2018. Conclusion and Relevance: Veterans had similar or higher adjusted prevalence and higher rates of increase over time for all pain variables compared to nonveterans. Continued pain prevalence increase among veterans may impact healthcare utilization (within and outside of the VHA), underscoring the need for improved pain prevention and care programs for these individuals with disproportionate pain burden.

Modeling the Association of Volume vs Composite Outcome Thresholds With Outcomes and Access to Transcatheter Aortic Valve Implantation in the US.

Importance: Professional societies and the Centers for Medicare & Medicaid Services suggest volume thresholds to ensure quality in transcatheter aortic valve implantation (TAVI). Objective: To model the association of volume thresholds vs spoke-and-hub implementation of outcome thresholds with TAVI outcomes and geographic access. Design, Setting, and Participants: This cohort study included patients who enrolled in the US Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy registry. Site volume and outcomes were determined from a baseline cohort of adults undergoing TAVI between July 1, 2017, and June 30, 2020. Exposures: Within each hospital referral region, TAVI sites were categorized by volume (<50 or ≥50 TAVIs per year) and separately by risk-adjusted outcome on the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy 30-day TAVI composite during the baseline period (July 2017 to June 2020). Outcomes of patients undergoing TAVIs from July 1, 2020, to March 31, 2022, were then modeled as though the patients had been treated at (1) the nearest higher volume (≥50 TAVIs per year) or (2) the best outcome site within the hospital referral region. Main Outcomes and Measures: The primary outcome was the absolute difference in events between the adjusted observed and modeled 30-day composite of death, stroke, major bleeding, stage III acute kidney injury, and paravalvular leak. Data are presented as the number of events reduced under the above scenarios with 95% bayesian credible intervals (CrIs) and median (IQR) driving distance. Results: The overall cohort included 166 248 patients with a mean (SD) age of 79.5 (8.6) years; 74 699 (47.3%) were female and 6657 (4.2%) were Black; 158 025 (95%) were treated in higher-volume sites (≥50 TAVIs) and 75 088 (45%) were treated in best-outcome sites. Modeling a volume threshold, there was no significant reduction in estimated adverse events (-34; 95% CrI, -75 to 8), while the median (IQR) driving time from the existing site to the alternate site was 22 (15-66) minutes. Transitioning care to the best outcome site in a hospital referral region resulted in an estimated 1261 fewer adverse outcomes (95% CrI, 1013-1500), while the median (IQR) driving time from the original site to the best site was 23 (15-41) minutes. Directionally similar findings were observed for Black individuals, Hispanic individuals, and individuals from rural areas. Conclusions and Relevance: In this study, compared with the current system of care, a modeled outcome-based spoke-and-hub paradigm of TAVI care improved national outcomes to a greater extent than a simulated volume threshold, at the cost of increased driving time. To improve quality while maintaining geographic access, efforts should focus on reducing site variation in outcomes.

Complications of Intravenous Tenecteplase Versus Alteplase for the Treatment of Acute Ischemic Stroke: A Systematic Review and Meta-Analysis.

BACKGROUND: Prior systematic reviews have compared the efficacy of intravenous tenecteplase and alteplase in acute ischemic stroke, assigning their relative complications as a secondary objective. The objective of the present study is to determine whether the risk of treatment complications differs between patients treated with either agent. METHODS: We performed a systematic review including interventional studies and prospective and retrospective, observational studies enrolling adult patients treated with intravenous tenecteplase for ischemic stroke (both comparative and noncomparative with alteplase). We searched MEDLINE, Embase, the Cochrane Library, Web of Science, and the www. CLINICALTRIALS: gov registry from inception through June 3, 2022. The primary outcome was symptomatic intracranial hemorrhage, and secondary outcomes included any intracranial hemorrhage, angioedema, gastrointestinal hemorrhage, other extracranial hemorrhage, and mortality. We performed random effects meta-analyses where appropriate. Evidence was synthesized as relative risks, comparing risks in patients exposed to tenecteplase versus alteplase and absolute risks in patients treated with tenecteplase. RESULTS: Of 2226 records identified, 25 full-text articles (reporting 26 studies of 7913 patients) were included. Sixteen studies included alteplase as a comparator, and 10 were noncomparative. The relative risk of symptomatic intracranial hemorrhage in patients treated with tenecteplase compared with alteplase in the 16 comparative studies was 0.89 ([95% CI, 0.65-1.23]; I2=0%). Among patients treated with low dose (<0.2 mg/kg; 4 studies), medium dose (0.2-0.39 mg/kg; 13 studies), and high dose (≥0.4 mg/kg; 3 studies) tenecteplase, the RRs of symptomatic intracranial hemorrhage were 0.78 ([95% CI, 0.22-2.82]; I2=0%), 0.77 ([95% CI, 0.53-1.14]; I2=0%), and 2.31 ([95% CI, 0.69-7.75]; I2=40%), respectively. The pooled risk of symptomatic intracranial hemorrhage in tenecteplase-treated patients, including comparative and noncomparative studies, was 0.99% ([95% CI, 0%-3.49%]; I2=0%, 7 studies), 1.69% ([95% CI, 1.14%-2.32%]; I2=1%, 23 studies), and 4.19% ([95% CI, 1.92%-7.11%]; I2=52%, 5 studies) within the low-, medium-, and high-dose groups. The risks of any intracranial hemorrhage, mortality, and other studied outcomes were comparable between the 2 agents. CONCLUSIONS: Across medium- and low-dose tiers, the risks of complications were generally comparable between those treated with tenecteplase versus alteplase for acute ischemic stroke.

The Impact of Hearing Loss and Its Treatment on Health-Related Quality of Life Utility: a Systematic Review with Meta-analysis.

BACKGROUND: Hearing loss significantly impacts health-related quality of life (QoL), yet the effects of current treatments on QoL utility remain uncertain. Our objective was to describe the impact of untreated and treated hearing loss on QoL utility to inform hearing healthcare policy. METHODS: We searched databases for articles published through 02/01/2021. Two independent reviewers screened for articles that reported elicitation of general QoL utility values for untreated and treated hearing loss health states. We extracted data and quality indicators from 62 studies that met the inclusion criteria. RESULTS: Included studies predominately used observational pre/post designs (61%), evaluated unilateral cochlear implantation (65%), administered the Health Utilities Index 3 (HUI3; 71%), and were conducted in Europe and North America (84%). In general, treatment of hearing loss improved post-treatment QoL utility when measured by most methods except the Euro-QoL 5 dimension (EQ-5D). In meta-analysis, hearing aids for adult mild-to-moderate hearing loss compared to no treatment significantly improved HUI3-estimated QoL utility (3 studies; mean change=0.11; 95% confidence interval (CI): 0.07 to 0.14) but did not impact EQ-5D-estimated QoL (3 studies; mean change=0.0; 95% CI: -0.03 to 0.04). Cochlear implants improved adult QoL utility 1-year post-implantation when measured by the HUI3 (7 studies; mean change=0.17; 95% CI: 0.11 to 0.23); however, pediatric VAS-estimated QoL utility was non-significant (4 studies; mean change=0.12; 95% CI: -0.02 to 0.25). The quality of included studies was limited by failure to report missingness of data and low survey response rates. Our study was limited by heterogeneous study populations and designs. FINDINGS: Treatment of hearing loss significantly improves QoL utility, and the HUI3 and VAS were most sensitive to improvements in hearing. Improved access to hearing healthcare should be prioritized. SYSTEMATIC REVIEW REGISTRATION: PROSPERO: CRD42021253314.

Robotic Esophagectomy Trends and Early Surgical Outcomes: The US Experience.

BACKGROUND: Recent esophagectomy trends were evaluated to describe the shift in surgical approach and outcomes using The Society of Thoracic Surgeons General Thoracic Surgery Database. METHODS: All patients who underwent an esophagectomy with gastric conduit from 2015 to 2019 were identified and analyzed according to original intended approach. After performing volume trend analysis of patients, operative outcomes were evaluated. RESULTS: Among 10,607 patients, esophagectomy was open in 5763 (54.3%), minimally invasive (MIE) in 3524 (33.2%), and robotic (RAMIE) in 1320 (12.4%). Within 5 years, MIE and RAMIE combined rose to majority approach (open from 58% to 42% of annual volume). While MIE and RAMIE were associated with higher rates of anastomotic leak, loss of conduit, pulmonary embolus, and reoperation, R0 resection and harvested number of lymph nodes exceeded those in open approaches. Operative mortality did not differ by approach (3.21% open vs 2.72% MIE vs 2.50% RAMIE; P = .2329). On multivariable analysis, RAMIE was independently associated with higher rate of anastomotic leak compared to open (adjusted odds ratio 1.53, 95% CI 1.14-2.04), while both MIE and RAMIE had lower mean length of stay. Propensity matching of 1320 pairs found a higher risk of anastomotic leak requiring surgery for RAMIE compared with MIE (adjusted odds ratio 1.39, 95% CI 1.01-1.92). CONCLUSIONS: In less than a decade, the dominant surgical approach in The Society of Thoracic Surgeons General Thoracic Surgery Database has become minimally invasive (RAMIE and MIE). While anastomotic leak and reoperation, more common in RAMIE, require a technical solution, these complications have not raised operative mortality. Further studies are needed to address long-term results and oncologic outcome.
