Rate of emergency lower extremity amputations in the United States among Medicare beneficiaries.
This study’s objective was to determine the rate of emergency versus elective lower extremity amputations in the US. The study evaluated Medicare beneficiaries who underwent lower extremity amputation between 2015 and 2020. The authors determined the rate for each zip code and placed into rank order from lowest to highest rate. They merged each beneficiary's place of residence and location of care with the American Hospital Association Annual Survey using Google Maps Application Programming Interface to determine the travel distance for patients to undergo their procedure. Of 233,084 patients, 66.3% were men, 69.8% were White. The average age at amputation was 74 years. There was wide variation in rates of emergency lower extremity amputation, with the quintile of zip codes demonstrating an emergency amputation rate of 3.7%, whereas the highest quintile demonstrating 90%. The median travel distance in the lowest emergency surgery rate quintile was 34.6 miles compared with 10.5 miles in the highest quintile of emergency surgery, suggesting variable access to essential vascular care.

Case sampling for evaluating hospital postoperative morbidity in US surgical quality improvement programs.
This study examined whether US surgical quality improvement (QI) programs using case sampling is robust enough for identifying hospitals with higher than expected complications. Eligible patients were 18 years and older who underwent a noncardiac operation at US Department of Veterans Affairs (VA) hospitals with a record in the VA Surgical Quality Improvement Program (systematic sample) and the VA Corporate Data Warehouse surgical domain (100% of surgical cases). Most patients in both samples were men (90.2% vs 91.2%) and White (74.7% vs 74.5%). Overall, 30-day complication rates were 7.6% and 5.3% for the sample and universal review cohorts, respectively. Using over 2145 hospital quarters of data, hospitals were identified as an outlier in 15.0% of quarters using the sample and 18.2% with universal review. Average hospital quarterly complication rates were 4.7% for outliers identified using the sample only, 7.2% for universal only, and 7.4% for concurrent identification in both sources. For nonsampled cases, average hospital quarterly complication rates were 7.0% at outliers and 4.4% at nonoutliers. Among outlier hospital quarters in the sample, 54.2% were concurrently identified with universal review, and for those identified with universal review, 44.6% were concurrently identified using the sample.

Emergency department utilization for pediatric gastrostomy tubes across the United States.
This study investigated the number and nature of emergency department (ED) visits to community hospitals for pediatric gastrostomy tube complication. The authors used the 2019 Nationwide Emergency Department Sample to perform a retrospective cross-sectional analysis of pediatric patients (<18 y) with a primary diagnosis of gastrostomy tube complication. Their primary outcome was a potentially preventable ED visit, defined as an encounter that did not result in any imaging, procedures, or an inpatient admission. They observed 32,036 ED visits at 535 hospitals and 15,165 (47.3%) were potentially preventable. Median age was 2 years, and 17,707 (55%) were male. Compared to White patients, patients with higher odds of potentially preventable visits were Black and Hispanic. Patients with residential zip codes in the first, second, and third median household income quartiles had higher odds of potentially preventable visits compared to the highest.

Association of bundled payments with spending, utilization, and quality for surgical conditions: a scoping review.
This scoping review assessed the body of literature examining episode-based bundled payment models effect on health care spending, utilization, and quality of care for surgical conditions. Bundled payment models let hospitals receive financial incentives to reduce spending on care provided to patients during a predefined clinical episode. The review queried four databases from inception through September 27, 2021. A total of 879 unique articles were found, of which 28 met final inclusion criteria. Of these studies, 23 out of 28 evaluated the impact of voluntary bundled payments in orthopedic surgery and found that bundled payments are associated with reduced spending on total care episodes, attributed primarily to decreases in post-acute care spending. This reduced spending did not worsen clinical outcomes (e.g., readmissions, complications, and mortality). Evidence for non-orthopedic surgery bundled payments remains limited.

Electronic health record-supported implementation of an evidence-based pathway for perioperative surgical care.
This study examines the role of electronic health records (EHRs) in implementing enhanced recovery pathways (ERPs) for perioperative surgical care. Interviews with informaticians and clinicians from eight US hospitals revealed three thematic clusters: "EHR difficulties," "EHR enablers," and "EHR barriers." Researchers concluded that high performers and improvers successfully integrated ERPs into EHRs with dedicated multidisciplinary teams, while others faced challenges. Early involvement of informatics expertise benefited ERP implementation and sustainability.

Medicare Advantage is associated with lower utilization of total joint arthroplasty.
To discover whether Medicare Advantage enrollees have a lower utilization of elective surgical procedures such as inpatient hip and knee total joint arthroplasty (TJA), which have usually been covered by traditional Medicare without restrictions, researchers conducted a cross-sectional study comparing traditional Medicare claims and Medicare Advantage encounter records for enrollees aged 65-85. Their results showed a lower incidence of TJA in Medicare Advantage enrollees. The interval from initial diagnosis to contact with an orthopedic surgeon and to the surgical procedure were shorter among traditional enrollees.

Fluoroscopic image-based behavior analysis can objectively explain subjective expert assessment of wire navigation skill.
This study evaluated best methods to assess surgical wire navigation skill, which can be objectively evaluated by analysis of intraoperative fluoroscopic image sequences. Prior work suggests that such image-based behavior analysis of operating room (OR) performance can predict performer experience level and agree with expert opinion (the current standard) on the quality of a final implant construct. Objective image-based evaluations were compared to expert assessments for entire technical OR performances. The relationship of three key variables were studied: (1) objective image-based criteria, (2) expert opinions, and (3) performing surgeon experience level. The authors used a paired-comparison survey of seven experts, based upon eight OR fluoroscopic wire navigation image sequences, which showed that the experts' preferences are best explained by objective metrics that reflect psychomotor and decision-making behaviors which are counter-productive to successful implant placement, like image count and behavior tally. One such behavior, adjustments away from goal, uniquely correlated well with all three key variables: a fluoroscopic image-based analysis composite score, expert consensus, and performer experience. The results confirmed that experts view less efficient technical behavior as indicative of lesser technical proficiency.

Variability in surgical approaches to hernias in patients with ascites.
This study investigated variability in surgical approaches to hernias in patients with ascites. The authors used data from the Michigan Surgical Quality Collaborative and its corresponding Core Optimization Hernia Registry (MSQC-COHR), which captures specific patient, hernia, and operative characteristics at a population level within the state. This retrospective cohort reviewed patients with ascites who had ventral or inguinal hernia repair surgery between January 2020 and May 3, 2022. The primary outcome observed was incidence and surgical approach for both ventral and inguinal hernia cohorts, and secondary outcomes included 30-day adverse clinical outcomes as listed here: (ED visits, readmission, reoperation, and complications) and surgical priority (urgent/emergent vs elective). In the cohort of 176 patients with ascites, only 1.4% of ventral hernia patients underwent hernia repair surgery, and only 0.2% of inguinal hernia patients. The post-operative 30-day adverse clinical outcomes in both hernia surgery cohorts were greatly increased compared to those without ascites (ventral: 32%; inguinal: 30%). Readmission was the most common complication, with a rate of 15.9% in the inguinal cohort, and 19.3% in the ventral hernia cohort. Open repair was the most common surgical approach (ventral: 86%, open: 77%). Ventral hernias were most commonly considered as urgent or emergency surgery (60%), while inguinal was mostly presented as elective surgery (72%).

Low-volume elective surgery and outcomes in Medicare beneficiaries treated at hospital networks.
This cross-sectional study’s objective was to quantify low-volume surgery and associated outcomes within hospital networks. This study used Medicare Provider Analysis and Review data to examine fee-for-service beneficiaries aged 66 to 99 years who underwent 1 of 10 elective surgical procedures (abdominal aortic aneurysm repair, carotid endarterectomy, mitral valve repair, hip or knee replacement, bariatric surgery, or resection for lung, esophageal, pancreatic, or rectal cancers) in a network hospital from 2016 to 2018. Hospital volume for each procedure (calculated with the use of National Inpatient Sample data) was compared with yearly hospital volume standards for that procedure recommended by The Leapfrog Group. The authors analyzed primary outcomes which were postoperative complications, 30-day readmission, and 30-day mortality, stratified by the volume status of the hospital and network type. Secondary outcome was the availability of a different high-volume hospital within the same network or outside the network and its proximity to the patient (based on hospital referral region and zip code). In all, data were analyzed for 950,079 Medicare fee-for-service beneficiaries (average age 74.4 years; 621,138 females and 427,931 males) who underwent 1,049,069 procedures at 2469 hospitals within 382 networks. Of these networks, almost 100% [380 (99.5%)] had at least 1 low-volume hospital performing the elective procedure of interest. In 79.8% of procedures that were performed at low-volume hospitals, there was a hospital that met volume standards within the same network and hospital referral region located a median (IQR) distance of 29 (12-60) miles from the patient's home. In adjusted analyses, postoperative outcomes were inferior at low-volume hospitals compared with hospitals meeting volume standards, with a 30-day mortality of 8.1% at low-volume hospitals vs 5.5% at hospitals that met volume standards.

Validation of measures for perioperative urinary catheter use, urinary retention, and urinary catheter-related trauma in surgical patients.
This article described a retrospective cohort study to analyze the effects of non-infectious urinary catheter-related complications, such as measurements of indwelling urinary catheter overuse, catheter-related trauma, and urinary retention. Participants were 200 patients who were undergoing general surgery operations; 65% had an indwelling urinary catheter placed at the time of surgery, 16% had urinary retention, and 6% had urinary trauma. The authors concluded that this study suggests a persistent high rate of catheter use, significant rates of urinary retention and trauma, and variation in the management of retention.

Contemporary trends in extent of surgery for differentiated thyroid cancer with extrathyroidal extension.
The study aimed to investigate trends in surgical approaches for differentiated thyroid cancer (DTC) with gross extrathyroidal extension (ETE). Using the National Cancer Database, patients with +ETE DTC from 2010 to 2020 were analyzed. Among 5,851 patients, 92% underwent total thyroidectomy (TT), but later years showed increased lobectomy rates. The results of the study suggest a potential shift towards preferring lobectomy in low-risk DTC cases, while raising concerns about undertreating high-risk patients.

Social risk and patient-reported outcomes after total knee replacement: implications for Medicare policy.
The objective of this study was to determine if county- or patient-level social risk factors are associated with patient-reported outcomes after total knee replacement when added to the comprehensive joint replacement risk-adjustment model. Patient and outcomes data from the Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement cohort were merged with the CDC Social Vulnerability Index. The findings indicated that patient-reported race, education, and income were associated with patient-reported pain or functional scores; pain improvement was negatively associated with Black race and positively associated with higher annual incomes. The authors concluded that these findings suggested that patient-level social factors warrant further investigation to promote health equity in patient-reported outcomes after total knee replacement.

Morphomics-informed population pharmacokinetic and physiologically-based pharmacokinetic modeling to optimize cefazolin surgical prophylaxis.
This study’s objective was to use algorithms that repurpose radiologic data into body composition (morphomics) to aid in informing dosing decisions for the antibiotic cefazolin for patients undergoing colorectal surgery who have obesity. This prospective study measured cefazolin plasma, fat, and colon tissue concentrations in these patients to develop a morphomics-informed population pharmacokinetic (PopPK) model to guide dose adjustments. A physiologically-based pharmacokinetic (PBPK) model was also constructed to inform tissue partitioning in 21 morbidly obese patients (body mass index ≥35 kg/m2 with one or more co-morbid conditions). Morphomics and pharmacokinetic data were available in 58 patients with a median weight of 95.9 kg and and 55 years, respectively. The plasma-to-subcutaneous fat partition coefficient was predicted to be 0.072 for the PopPK model and 0.060 for the PBPK model. Covariates of cefazolin exposure were identified as the estimated creatinine clearance (eCL(cr) ) and body depth at the third lumbar vertebra (body depth_L3). The authors concluded that kidney function and morphomics were more informative than body weight as covariates of cefazolin target site exposure. They advised that data from more diverse populations, consensus on target cefazolin exposure, and comparative studies are needed before a change in practice can be implemented.

Surgical approach and reoperation risk in intermittent exotropia in the IRIS Registry.
This cohort study compared the 5-year reoperation rates for children with intermittent exotropia (IXT). Reoperation rates for children with IXT treated with horizontal muscle strabismus surgery using bilateral lateral rectus recession (BLR) vs unilateral lateral rectus recession with medial rectus resection (RR) were compared. The authors examined data obtained from the Intelligent Research in Sight (IRIS) Registry on 7482 children (age, <18 years) with IXT who underwent horizontal eye muscle strabismus surgery, excluding children undergoing initial surgeries involving 3 or more horizontal muscles, vertical muscles, or reoperations. Primary outcome was the adjusted cumulative incidence of repeat horizontal muscle surgery within 5 years after the initial surgery. BLR was performed more frequently than RR (85.3% vs 14.7%), especially in younger children. After data adjustment, the 5-year cumulative incidence of reoperation was 21.3%. The adjusted 5-year cumulative incidence of reoperation was higher for BLR than for RR. Unilateral lateral rectus recession with medial rectus resection was associated with a lower 5-year reoperation risk compared with BLR. Younger age at time of initial surgery was associated with a higher reoperation risk.

Characterizing surgical site infection signals in clinical notes.
Building off of previous work for automated and semi-automated surgical site infections (SSIs) detection using expert-derived "strong features" from clinical notes, researchers hypothesized that additional SSI phrases may be contained in clinical notes. They systematically characterized phrases and expressions associated with SSIs. While 83 percent of expert-derived original terms overlapped with new terms and modifiers, an additional 362 modifiers associated with both positive and negative SSI signals were identified.

Perioperative timing of infliximab and the risk of serious infection after elective hip and knee arthroplasty.
The purpose of this retrospective cohort study was to evaluate the association between infliximab timing and serious infection after elective hip or knee arthroplasty. The investigators concluded that administering infliximab within 4 weeks of elective knee or hip arthroplasty was not associated with a higher risk of short- or long-term serious infection compared to withholding infliximab for longer time periods. They also concluded that glucocorticoid use, especially >10 mg/day, was associated with an increased infection risk.

The independent effect of cancer on outcomes: a potential limitation of surgical risk prediction.
This study aims to compare the use of common risk models for benign versus malignant gastrointestinal disease. It found that the National Surgical Quality Improvement Program (NSQIP) prediction models less effectively evaluate the risk of death in cancer patients as compared to patients with benign disease. A diagnosis of cancer is independently associated with an increased risk of surgical complications.

The IVC filter placement rate per 100 000 hospitalizations increased from 322.1 (n = 99 779) in 2005 to 412.0 (n = 129 026) in 2010, decreased to 374.1 (n = 117 731) in 2011, and continued declining to 321.8 (n = 95 735) in 2014. The percentage of prophylactic IVC filter placement decreased from 28.9 percent in 2005 to 22.6 percent in 2014.

Mechanical or biologic prostheses for aortic-valve and mitral-valve replacement.
This study compared long-term mortality and rates of reoperation, stroke, and bleeding between cohorts of patients who underwent primary aortic-valve replacement or mitral-valve replacement with a mechanical or biologic prosthesis. The long-term mortality benefit associated with a mechanical prosthesis, as compared with a biologic prosthesis, persisted until 70 years of age among patients undergoing mitral-valve replacement and until 55 years of age among those undergoing aortic-valve replacement.

Randomised controlled trial to assess the effect of a Just-in-Time training on procedural performance: a proof-of-concept study to address procedural skill decay.
The purpose of this study was to evaluate the impact of a novel Just-in-Time (JIT) intervention on transvenous pacemaker (TVP) placement during a simulated patient event. The authors concluded that a JIT intervention improved procedure performance, suggesting a role for JIT interventions in rarely performed procedures.
