Abstract
OBJECTIVES To determine whether hospital and surgeon volume are associated with outcomes after operative fixation of tibial shaft fractures. METHODS Adults (≥18 year old) who underwent operative fixation of diaphyseal tibial fractures were identified in the New York Statewide Planning and Research Cooperative System data set from 2001 to 2015. Reoperation, nonunion, and other adverse event rates were compared across surgeon and hospital volume using multivariable Cox proportional hazards regression, adjusting for clinical and demographic factors. Low-volume providers (lowest 20%) were compared with high-volume providers (highest 20%). Low volume constituted <5 cases/year for hospitals and 1 case/year for surgeons. High volume constituted ≥40 cases/year for hospitals and ≥8 cases/year for surgeons. RESULTS Nine thousand one hundred forty-seven patients were included. Relative to high-volume surgeons, low-volume surgeons experienced slightly higher rates of pneumonia [2% vs. 1%, hazard ratio (HR) 2.50, 95% confidence interval (CI) 1.38-4.53, P = 0.003], and respiratory failure (5% vs. 3%, HR 1.88, 95% CI 1.30-2.71, P = 0.001). Compared with high-volume hospitals, low-volume hospitals experienced slightly lower rates of compartment syndrome (1% vs. 3%, HR 0.45, 95% CI 0.24-0.85, P = 0.01) and fasciotomies (3% vs. 7%, HR 0.57, 95% CI 0.38-0.85, P = 0.005). The rates of all other reoperations and adverse events compared among hospitals and surgeons were not significantly different. CONCLUSIONS We did not detect a clinically meaningful volume-outcome relationship for either surgeons or hospitals despite the use of a robust database with rigorous statistical methodology. Of note, these findings should not be applied to rare complex injuries such as those with extensive bone loss or articular extension, which are not well represented by this study population. Therefore, we conclude that typical tibial shaft fracture, including open or closed injuries, can be safely managed in the vast majority of orthopaedic settings and that this care does not necessarily require transfer to a specialty centers. Future research into orthopaedic volume-outcome relationships could be strengthened by the use of functional outcomes (which would likely require well-organized multicenter prospective registries). LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Objectives:
Cardiac amyloidosis is an underdiagnosed cause of heart failure (HF). We investigated the prevalence and impact of amyloidosis in HF.
Methods:
All hospitalizations for primary diagnosis of HF between January 1, 2010, and August 31, 2015 were identified in the National Readmission Database (NRD). Of these, hospitalizations with amyloidosis were matched in a 3:1 fashion to hospitalizations without amyloidosis using the year of admission, discharge quarter, age, sex, and Charlson comorbidity index. Primary outcomes of interest were inpatient mortality and 30-day readmission. Multivariable logistic regression models were used to estimate the association of HF with amyloidosis with adverse clinical outcomes.
Results:
Overall, 2,846 (0.2%) hospitalizations had HF with amyloidosis. Hospitalizations for HF with amyloidosis had a higher prevalence of renal disease (56% vs. 45%), atrial fibrillation (48% vs 42%) and malignancy (20% vs 4%) as compared with HF without amyloidosis. In adjusted analyses, HF with amyloidosis had higher odds of in-hospital mortality (6% vs. 3%; OR 1.60, 95% CI 1.28, 2.00), 30-day readmission (OR 1.18, 95% CI 1.06, 1.32), and longer length of stay (CIE 1.73, 95% CI 1.44, 2.03). Among the HF with amyloidosis group, there were similar incidences of CV and non-CV-related readmissions (48% and 52%, respectively), but HF was the most common primary readmission diagnosis, constituting 35% of all readmissions. The incidence of inpatient mortality and 30-day readmission did not change significantly over time during the study period for either HF hospitalizations with or without amyloidosis.
Conclusion:
In decompensated HF, presence of amyloidosis was associated with higher risk of inpatient mortality and 30-day readmission.

[PMID: 31918987 DOI: 10.1016/j.arth.2019.11.044] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 11/23/2019] [Accepted: 11/30/2019] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND This study evaluates whether very high-volume hip arthroplasty providers have lower complication rates than other relatively high-volume providers. METHODS Hemiarthroplasty patients ≥60 years old were identified in the New York Statewide Planning and Research Cooperative System 2001-2015 dataset. Low-volume hospitals (<50 hip arthroplasty cases/y) and surgeons (<10 cases/y) were excluded. The upper and lower quintiles were compared for the remaining "high-volume" hospitals (50-70 vs >245) and surgeons (10-15 vs ≥60) using multivariable Cox proportional hazards regression. Multiple sensitivity analyses were performed treating volume as a continuous variable. RESULTS In total, 48,809 patients were included. Very high-volume hospitals demonstrated slightly less pneumonia (6% vs 7%, hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.68-0.88, P < .0001). Very high-volume surgeons experienced slightly higher rates of inpatient morality (3% vs 2%, HR 1.30, 95% CI 1.06-1.60, P = .01), revision surgery (3% vs 3%, HR 1.24, 95% CI 1.02-1.52, P = .03), and implant failure (1% vs <1%, HR 1.80, 95% CI 1.10-2.96, P = .02). Sensitivity analyses did not significantly alter these findings but suggested that inpatient mortality may decline as surgeon volume approaches 30 cases/y before gradually increasing at higher volumes. CONCLUSION A clinically meaningful volume-outcome relationship was not identified among very high-volume hemiarthroplasty surgeons or hospitals. Although prior evidence indicates that outcomes can be improved by avoiding very low-volume providers, these results suggest that complications would not be further reduced by directing all hemiarthroplasty patients to very high-volume surgeons or facilities. Future research investigating whether inpatient mortality changes with surgeon volume (particularly around 30 cases/y) in a different dataset would be valuable. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
INTRODUCTION In the past two decades, three prospective randomized trials demonstrated that elderly women with early stage hormone positive breast cancer had equivalent disease-specific mortality regardless of axillary surgery. In 2016, the Choosing Wisely campaign encouraged patients and providers to reconsider the role of axillary surgery in this population. We sought to identify factors that contribute to adopting non-operative management of the axilla in these patients. MATERIALS AND METHODS We performed a retrospective analysis of women ≥ 70 years old with cT1/T2, hormone positive invasive ductal carcinoma who underwent partial or total mastectomy, with/without axillary surgery, and did not receive adjuvant chemotherapy from the National Cancer Database from 2004 to 2015. We used multivariable log-binomial regression to model the risk of undergoing axillary surgery across region, care setting, and Charlson-Deyo scores, and analyzed temporal trends using Poisson regression. From 2004 to 2015, 87,342 of 99,940 women who met inclusion criteria (83%) had axillary surgery. Over time, axillary surgery increased from 78% to 88% (p < 0.001). This rise was consistent across region (p = 0.81) and care setting (p = 0.09), but flattened as age increased (p < 0.001). Omitting axillary surgery was more likely in patients treated in New England (RR 0.88, 95% CI 0.86, 0.89) and patients ≥ 85 (RR 0.66, 95% CI 0.65, 0.67). CONCLUSIONS Axillary surgery continues to be the preferred option of axillary management in elderly women with early stage, clinically node negative, hormone-positive, invasive breast cancer despite no survival benefit. Identifying factors to improve patient selection and dissemination of current recommendations can improve adoption of current evidence on axillary surgery in the elderly.

Abstract
Background Atrial fibrillation (AF) is common in patients undergoing transcatheter aortic valve replacement (TAVR) but there is conflicting evidence on whether AF impacts outcomes after TAVR. Methods Hospitalizations of adults ≥50 years old who had undergone elective TAVR from 2012 to 2015 were included. Poisson regression was used to assess changes in in-hospital complications, average length of stay (LOS) after TAVR, and discharge disposition over time. Multivariable logistic, linear, and generalized logistic regression models, adjusting for patient and hospital characteristics, were used to estimate the effect of AF on inpatient outcomes. Results A total of 7,266 TAVR hospitalizations were included; AF was present in 44% of patients. Between 2012 and 2015, there was a significant decrease in the incidence of acute kidney injury, blood transfusion, average LOS, and inpatient mortality both for AF and non-AF patients. However, the incidences of vascular complications and major bleeding decreased only among non-AF patients. After adjustment, AF was associated with increased incidences of TIA/stroke (OR 1.36, 95% CI: 1.01, 1.85), acute kidney injury (OR 1.54, 95% CI: 1.33, 1.78), blood transfusion (OR 1.14, 95% CI: 1.00, 1.30), transfer to a skilled nursing facility (OR 1.38, 95% CI: 1.23, 1.55), and longer average LOS (CIE 1.30, 95% CI: 1.06, 1.54). AF was not associated with inpatient mortality (OR 1.09, 95% CI: 0.81, 1.48). Conclusions AF is prevalent among patients undergoing TAVR, and is associated with higher incidences of inpatient complications, discharge to a skilled nursing facility, and longer average LOS. While the incidence of many complications has declined in the past few years, continued efforts to further reduce complications in patients with AF is urgently required for expansion of TAVR to broader populations.

Abstract
OBJECTIVE Understanding modifiable risk factors to improve surgical outcomes is increasingly important in value-based health care. There is an established association between peripheral artery disease (PAD), diabetes, and limb loss, but less is known about expected outcomes after revascularization relative to the degree of glycemic control. The purpose of this study was to determine the association between hemoglobin A1c (HbA1c) management in diabetics and surgical outcomes after open infrainguinal bypass. METHODS The Vascular Quality Initiative infrainguinal bypass module was used to identify adult patients (≥18 years) with a history of diabetes who underwent bypass for PAD between 2011 and 2018. Exclusion criteria included missing or illogical HbA1c values and if the indication for the limb treated was not PAD. Patients were categorized by preoperative HbA1c levels as low severity/controlled (<7.0%), high severity (7.0%-10.0%), and very high severity (>10.0%). Primary outcomes were 30-day incidence of major adverse cardiac events (MACEs), major adverse limb events (MALEs), ipsilateral amputation, and 1-year all-cause mortality. Thirty-day outcomes were calculated using multivariable regression to compute odds ratios; hazard ratios were calculated for all-cause mortality. All analyses were adjusted for demographics, comorbidities, and clinical characteristics. RESULTS The final sample included 30,813 operations (27,988 unique patients): 17,517 (57%) nondiabetic patients, 5194 patients with low-severity/controlled diabetes, and 8102 (26%) patients with poorly controlled diabetes, including 5531 (70%) treated with insulin. There were 6439 (21%) patients with high-severity HbA1c values and 1663 (5%) patients with very-high-severity HbA1c values. Those with a very high HbA1c level were more likely to be nonwhite, insulin dependent, and active smokers. Compared with nondiabetics, patients with very-high-severity HbA1c had an 81% increase in MACEs and 31% increase in MALEs, whereas patients with high-severity HbA1c only had a 49% increase in MACEs and a 12% increase in MALEs. Each one-step increase in severity category (eg, low to high to very high) was associated with an average 29% increase in the odds of MACEs and an 8% increase in the odds of MALEs. CONCLUSIONS Uncontrolled diabetes with an HbA1c value >10.0% was associated with significantly worse 30-day surgical outcomes. Patients with incrementally better glycemic control (HbA1c level of 7.0%-10.0%) did not suffer the same rate of complications, suggesting that preoperative attempts at improving diabetes management even slightly could lead to improved surgical outcomes in open infrainguinal bypass patients.

Abstract
BACKGROUND The purpose of this study was to (1) determine the incidence of postoperative urinary retention (POUR) in patients undergoing lung resection at our institution, (2) identify differences in potential risk factors between patients with and without POUR, and (3) describe patient outcomes across POUR status. METHODS The medical records of 225 patients between 2016 and 2017 were reviewed, and 191 met criteria for inclusion. The institution's catheterization removal protocol was followed in all patients. Recatheterization was defined as requiring in-and-out catheterization or Foley catheter placement. Fisher exact and Wilcoxon tests were used for analysis. RESULTS POUR developed in 35 patients (18%). Patients with POUR were older (P = .01), had increased baseline creatinine (P = .04), and a higher prevalence of benign prostatic hyperplasia (P = .007). POUR patients were also less likely to get a Foley catheter intraoperatively (P = .0002). Other intraoperative factors, such as surgical approach and extent of resection, were not significantly different between patients with and without POUR. Postoperative factors (epidural use or days with chest tube) were similar. Although patients with POUR were more likely to be discharged with a Foley catheter (13% vs 0%, P = .002), no difference in length of stay, incidences of urinary tract infections, or 30-day readmission were observed. CONCLUSIONS POUR develops in approximately 1 in 5 patients undergoing lung resection. Patients with POUR were more likely to not have a Foley catheter placed intraoperatively. However, patients who had POUR did not have worsened patient outcomes (urinary tract infections, length of stay, or 30-day readmission).

Abstract
Single hepatocellular carcinoma (HCC) tumors can be successfully eradicated with thermal ablation (TA). We assessed the validity of the Liver Imaging Reporting and Data System Treatment Response (LR-TR) criteria with a retrospective analysis of a single-center database of patients with small HCC tumors (<3 cm in diameter) who underwent both laparoscopic TA and liver transplantation (LT) from 2004 to 2018. Postablation MRIs were assigned LR-TR categories (nonviable, equivocal, and viable) for ablated lesions and Liver Imaging Reporting and Data System (LI-RADS) categories (probable or definite HCC) for untreated lesions. Interpretations were compared with the histopathology of the post-LT explanted liver. There were 45 patients with 81 tumors (59 ablated and 22 untreated; mean size, 2.2 cm), and 23 (39%) of the ablated tumors had viable HCC on histopathology. The sensitivity/specificity of LR-TR categories (nonviable/equivocal versus viable) of ablated tumors was 30%/99%, with a positive predictive value (PPV)/negative predictive value (NPV) of 93%/69%. The sensitivity varied with residual tumor size. The sensitivity/specificity of LI-RADS 4 and 5 diagnostic criteria at detecting new HCC was 65%/94%, respectively, with a PPV/NPV of 85%/84%. The interrater reliability (IRR) was high for LR-TR categories (90% agreement, Cohen's ĸ = 0.75) and for LI-RADS LR-4 and LR-5 diagnostic categories (91% agreement, Cohen's ĸ = 0.80). In patients with HCC <3 cm in diameter, LR-TR criteria after TA had high IRR but low sensitivity, suggesting that the LR-TR categories are precise but inaccurate. The low sensitivity may be secondary to TA's disruption in the local blood flow of the tissue, which could affect the arterial enhancement phase on MRI. Additional investigation and new technologies may be necessary to improve imaging after ablation.

Abstract
Background: Inguinal hernia repair is one of the more common procedures performed in the United States. The optimal surgical approach, however, remains controversial. We aimed to compare the postoperative outcomes and costs between laparoscopic and open inpatient inguinal hernia repairs in a national cohort. Materials and Methods: We performed a retrospective analysis of the National Inpatient Sample during the period 2009-2015. Adult patients (≥18 years old) undergoing laparoscopic and open inguinal hernia repair were included. Multivariable logistic, generalized logistic, and linear regression were used to assess the effect of the laparoscopic approach on postoperative complications, mortality, length of stay, and hospital charges. Results: A total of 41,937 patients undergoing open inguinal hernia repair (N = 36,575) and laparoscopic inguinal hernia repair (N = 5282) were included. Patients undergoing laparoscopic inguinal hernia repair were less likely to have postoperative wound complications (odds ratio [OR]: 0.64, 95% confidence interval [CI]: 0.41-0.98), infection (OR: 0.34, 95% CI: 0.27-0.42), bleeding (OR: 0.72, 95% CI: 0.63-0.82), cardiac failure (OR: 0.72, 95% CI: 0.64-0.82), renal failure (OR: 0.54, 95% CI: 0.47-0.62), respiratory failure (OR: 0.70, 95% CI: 0.58-0.85), and inpatient mortality (OR: 0.27, 95% CI: 0.17-0.40). On average, the laparoscopic approach reduced length of stay by 1.28 days (95% CI: -1.58 to -1.18), and decreased hospital costs by $2400 (95% CI: -$4700 to -$700). Conclusion: Laparoscopic hernia repair is associated with significantly lower rates of postoperative morbidity and mortality, shorter length of hospital stays, and lower hospital costs for inpatient repairs. The laparoscopic approach should be encouraged for the management of appropriate patients with inpatient inguinal hernias.

Abstract
BACKGROUND We aimed to identify differences in disparities among patients with a cancer in which screening is widely recommended (colorectal cancer [CRC]) and one in which it is not (esophageal cancer). METHODS A retrospective analysis was performed using 2004-2015 data from the National Cancer Database. Multivariable generalized logistic regression was used to identify potential differences in the effect of disparities in stage at diagnosis. RESULTS A total of 96,524 esophageal cancer patients and 361,187 CRC patients were included. Black patients, longer travel distances, and lower educational attainment were only associated with increased odds of stage IV CRC. While both Medicaid and uninsured patients were more likely to be diagnosed with stage IV esophageal and CRC, the effect was larger among CRC patients. From 2004 to 2015, the rates of stage IV esophageal cancer decreased from 42.0% to 38.2%, while the rates of stage IV CRC increased from 36.9% to 40.8% (p < 0.0001). CONCLUSIONS Disparities are more pronounced in CRC, compared to esophageal cancer. Equity in access to screening and cancer care should be prioritized.

Abstract
Background Octogenarians have low physiologic reserve and may benefit more from transcatheter aortic valve replacement (TAVR) than surgical aortic valve replacement (SAVR). Methods and Results This retrospective cohort study based on the National Inpatient Sample included octogenarians who underwent TAVR or SAVR from 2012 to 2015. Crude and standardized‐morbidity‐ratio‐weighted regression models were used to compare in‐hospital outcomes. Among 19 145 TAVR and 9815 SAVR hospitalizations, TAVR patients had higher Charlson Comorbidity Index (CCI) scores (2.0 versus 0.8, P<0.0001) than SAVR patients. Before weighting, TAVR was associated with significantly shorter length of stay, more home discharges, and lower incidences of acute kidney injury, bleeding, and cardiogenic shock. Associations were consistent across Charlson Comorbidity Index, except for TAVR being associated with greater length of stay reductions among patients with Charlson Comorbidity Index ≥2, compared with Charlson Comorbidity Index <2 (change in estimate −3.56 versus −2.61 days, P=0.004). After weighting, TAVR patients had significantly shorter length of stay (change in estimate −3.29 days, 95% CI −3.82, −2.75) and lower odds of transfer to skilled nursing facility (odds ratio 0.34, 95% CI 0.29, 0.41), acute kidney injury (odds ratio 0.55, 95% CI 0.45, 0.68), bleeding (odds ratio 0.44, 95% CI 0.37, 0.53), and cardiogenic shock (odds ratio 0.55, 95% CI 0.33, 0.92), compared with SAVR patients. Odds of permanent pacemaker implantation, transient ischemic attack/stroke, vascular complications, and in‐hospital mortality were not significantly different. Conclusions TAVR may be preferred over SAVR in high‐risk octogenarians because of shorter length of stay, better discharge disposition, and less acute kidney injury, and bleeding. All octogenarians may benefit more from TAVR, irrespective of comorbidity burden, but additional research is needed to confirm our findings. See Editorial by Himbert et al

Abstract
BACKGROUND Despite data demonstrating the safety of omitting axillary surgery in older women with early-stage breast cancer, the incidence of axillary surgery remains high. It was hypothesized that the prevalence of nodal positivity would decrease with advancing age. METHODS The National Cancer Data Base was used to construct a cohort of adult women with early-stage, clinically node-negative, estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative breast cancer treated between 2013 and 2015. Multivariable logistic regression was used to assess the relationship between age and nodal positivity, and this was stratified by the axillary surgery category. Modified Poisson regression was used to estimate the proportion of women receiving adjuvant therapy according to age and nodal status. RESULTS The incidence of axillary surgery among women aged 70 and older (n = 51,917) remained high nationwide (86%). There was a significant decrease in nodal positivity with advancing age in women with early-stage, ER+, clinically node-negative breast cancer from the youngest cohort up to patients aged 70 to 89 years, and this was independent of histologic subtype (ductal vs lobular), race, comorbidities, and socioeconomic factors. Overall, less than 10% of women aged 70 or older who underwent surgery had node-positive disease, regardless of axillary surgery type, and almost 95% of node-positive patients aged 70 or older were at pathological stage N1mi or N1. CONCLUSIONS Axillary surgery may be safely omitted for many older women with ER+, clinically node-negative, early-stage breast cancer. Nodal positivity declines with advancing age, and this suggests varied biology in older patients versus younger patients.

Abstract
PURPOSE Herniorrhaphy is a source of substantial cost and morbidity. Although women are a substantial proportion of patients seeking repair, gender-specific data, including the influence of childbirth on hernia recurrence, are lacking. Our objective was to estimate the rate and identify risk factors for repeat herniorrhaphy in reproductive-aged women. METHODS Retrospective cohort study of women who underwent herniorrhaphy during June 2000-December 2014 in the United States. Women aged 18-50 who underwent umbilical, incisional/ventral, or inguinal/femoral herniorrhaphy in the Truven Health Analytics MarketScan® Commercial Claims and Encounters database were included. Women without a hernia diagnosis or multiple/concurrent index herniorrhaphy types were excluded. Primary outcome of interest was second herniorrhaphy. RESULTS Of 123,674 women, 13% had a second herniorrhaphy within 10 years; increasing age, comorbidities, childbirth, smoking, obesity, and inpatient procedure were independently associated with increased risk. Cesarean delivery before umbilical herniorrhaphy (HR 1.61, 95% CI 1.34, 1.92) and both vaginal (HR 2.57, 95% CI 1.98, 3.34) and cesarean delivery (HR 2.95, 95% CI 2.25, 3.87) after umbilical herniorrhaphy were associated with increased risk of second herniorrhaphy. Both vaginal (HR 1.66, 95% CI 1.13, 2.43) and cesarean delivery (HR 2.72, 95% CI 2.09, 3.53) after incisional/ventral herniorrhaphy and vaginal delivery after inguinal/femoral herniorrhaphy (HR 1.75, 95% CI 1.22, 2.51) were associated with increased risk of second herniorrhaphy. CONCLUSIONS Among reproductive-aged women, childbirth, increasing age, comorbidities, smoking, and obesity increase risk of subsequent herniorrhaphy. Risk of second herniorrhaphy is higher with cesarean delivery compared to vaginal delivery, and higher for delivery occurring after initial hernia repair compared to before.

Abstract
Background Transcatheter aortic valve replacement (TAVR) has solidified the importance of a heart team and revolutionized patient selection for surgical aortic valve replacement (SAVR). It is unknown if hospital ability to offer TAVR impacts SAVR outcomes. We investigated outcomes after SAVR between TAVR and non-TAVR centers. Methods and Results Hospitalizations of patients aged ≥50 years, undergoing elective SAVR between January 2012 and September 2015, in the National Readmission Database (NRD) were included. Multivariable logistic, linear, and generalized logistic regression models were used to adjust for patient and hospital characteristics and estimate association between undergoing SAVR at a TAVR center, compared with a non-TAVR center. The association between TAVR volumes and these outcomes were also assessed. SAVR hospitalizations (n = 32 198) were identified; 22 066 (69%) at TAVR and 10 132 (31%) at non-TAVR centers. SAVRs at TAVR centers had lower odds of inpatient mortality (odds ratio 0.67, 95% CI 0.55-0.82) and discharge to skilled nursing facility (odds ratio 0.92, 95% CI 0.85-0.99), compared with non-TAVR centers. There was no difference in LOS (change in estimate -0.09, 95% CI -0.26 to 0.08) or 30-day re-admission (odds ratio 0.95, 95% CI 0.88-1.03). SAVRs performed at the highest TAVR volume centers had the lowest inpatient mortality, compared with non-TAVR centers (odds ratio 0.43 95% CI 0.29-0.63). Conclusions Patients undergoing SAVR at TAVR centers are more likely to survive and have better discharge disposition than patients undergoing SAVR at non-TAVR centers. Whether this represents benefits of a heart-team approach to care or differences in patient selection for SAVR when TAVR is unavailable requires further study.
