Disparities in advance care planning rates persist among emergency general surgery patients: current state and recommendations for improvement.
A sudden shift in health condition and the intensification of chronic conditions often necessitate the consideration of emergency general surgery (EGS). While goal-oriented care discussions can enhance goal-concordant care and mitigate feelings of depression and anxiety in patients and caregivers, such conversations, along with standardized documentation, are seldom conducted for EGS patients. The researchers conducted a retrospective cohort study employing data from electronic health records of patients admitted to the EGS service in a high-level academic center to ascertain the frequency of significant advance care planning (ACP) documentation (discussions and legal ACP forms) during EGS hospitalization. Multivariable regression was used to identify patient, clinician, and procedural elements contributing to the absence of ACP. The study found that out of the 681 patients admitted to the EGS service in 2019, only 20.1% had ACP documentation in the electronic health record at any stage during their hospital stay. Two-thirds (65.8%) of the entire cohort underwent surgery during their admission, but none of them had an ACP conversation documented with the surgical team before the operation. Patients with ACP documentation were likely to be insured by Medicare and had a higher incidence of comorbid conditions.

Perioperative risks of sleeve gastrectomy versus roux-en-Y gastric bypass among patients with chronic kidney disease: a review of the MBSAQIP database.
The purpose of this study was to determine whether patients with chronic kidney disease experienced higher rates of perioperative complications after roux-en-Y gastric bypass (RYGB) compared to sleeve gastrectomy. The investigators concluded that among well-matched cohorts of RYGB and sleeve gastrectomy patients, incidence of primary outcomes were similar. Among secondary outcomes, only acute kidney injury was statistically-significantly higher among RYGB patients; however, the E-value for this difference was small and relatively weak confounder(s) could abrogate the statistical difference.

Effect of concomitant deep venous reflux on truncal endovenous ablation outcomes in the Vascular Quality Initiative.
This study looked at outcomes for patients with varicose veins (C2 disease) undergoing truncal endovenous ablation with and without deep venous reflux. Data from the Vascular Quality Initiative was analyzed from 2015 to 2019. A total of 4881 patients were included, with 46.2% having combined deep and superficial reflux. Follow-up around a year later (median 336.5 days) was conducted after. Patients with deep reflux were less likely to be female, more likely to be Caucasian, and had no difference in BMI. Additionally, there were no differences in rates of prior varicose vein treatments, number of pregnancies, or history of deep venous thrombosis. However, patients without deep reflux were more likely to use anticoagulants at the time of the procedure. Patients without deep reflux had slightly higher median preprocedural Venous Clinician Severity Score (VCSS) scores as well as postprocedural VCSS scores. Total symptom score was higher for patients without deep reflux before and after the procedure, but there was no change in symptom score after the procedure. Patients with deep reflux had substantially higher rates of complications with a particular increase in proximal thrombus extension.

Outcomes after truncal ablation with or without concomitant phlebectomy for isolated symptomatic varicose veins (C2 disease).
This study looked outcomes of patients with varicose veins (C2 disease) who were treated with venous ablation alone or ablation plus phlebectomy using the Vascular Quality Initiative Varicose Vein Registry. Data between January 2015 and March 2015 was used to investigate postoperative as well as long-term clinical and patient-reported outcomes among patients with documented symptomatic C2 disease undergoing truncal endovenous ablations alone and combined ablation and phlebectomy. Out of 3375 patients, 40.1% underwent isolated truncal ablation and the rest had the combined procedure of ablation and phlebectomy. Complications were low for both procedures (8.4% and 8.7%). Overall, improvement in symptoms was experienced by 94.4% of patients with more increases in patients undergoing ablation and phlebectomy than ablation alone. Both procedures are recommended by the authors to be covered by insurance.

Hospital resource use after hip reconstruction surgery in children with neurological complex chronic conditions.
This study assessed how co-occurring conditions influence recovery after hip reconstruction surgery in children with neurological complex chronic conditions (CCCs). This retrospective analysis of 4058 children age 4 years or older was conducted from 2015 to 2018 in 49 children’s hospitals. The presence of CCCs was assessed using the AHRQ Chronic Condition Indicator system. Outcomes looked for included postoperative hospital length of stay (LOS), 30 -day readmission rates, and median hospital costs. The most common co-occurring conditions were digestive (60.1%) and respiratory (37.9%). Median LOS increased 67% as co-existing conditions increased from one to four or more. Median hospital costs increased 41% and readmission rates increased 250%. Malnutrition was associated with the greatest increase in postoperative hospital use.

Comparison of unilateral vs bilateral and staged bilateral vs concurrent bilateral truncal endovenous ablation in the Vascular Quality Initiative.
This study compares outcomes in patients who have undergone unilateral vs bilateral venous ablation procedures or between staged and concurrent bilateral procedures. Data from the Vascular Quality Initiative from 2015 to 2019 was used to investigate immediate postoperative as well as long-term clinical and patient-reported outcomes. A total of 5029 patients were included, of whom 75.2% underwent unilateral procedures. Follow-up was conducted with a median of 227 days after. Unilateral patients were less likely to be female and white and had lower BMI compared with patients undergoing bilateral procedures. In addition, unilateral patients had fewer prior varicose vein treatments and had higher Venous Clinical Severity Scores (VCSS). There were no differences in complications in patients undergoing unilateral vs bilateral procedures. Systemic complications were rare in both groups.

Impact of diabetes on 90-day episodes of care after elective total joint arthroplasty among Medicare beneficiaries.
This study examined the impact of diabetes on 90-day episodes of care after elective total knee arthroplasty (TKA) and total hip arthroplasty (THA) in the United States. Complication (n = 521,230) and readmission (n = 515,691) data was extracted on Medicare beneficiaries using files from 2013 and 2014. Diabetes status was identified with ICD-9 codes. The odds ratio (OR) of TKA complications was significantly higher for patients with uncontrolled diabetes than those with no diabetes. The OR of THA complications was also significantly higher for controlled-complicated diabetes. OR of readmission was significantly higher for all diabetes groups.

Trends, perioperative adverse events, and survival of patients with left ventricular assist devices undergoing noncardiac surgery.
This longitudinal cohort study examined outcomes of noncardiac surgery (NCS) in patients with left ventricular assist devices (LVADs). This study examined patients enrolled in Medicare who had undergone durable LVAD implantation from January 2012 to November 2017 with follow-up through December 2017. Primary outcome after NCS was major adverse cardiovascular events (MACEs), defined as in-hospital or 30-day all-cause mortality, ischemic stroke, or intracerebral hemorrhage. Of the 8118 patients with LVAD, 1326 underwent NCS with 75.4% emergent or urgent, and 24.6% elective. Both elective and urgent or emergent NCS was associated with higher mortality early and late compared with patients with LVAD who did not undergo NCS.

Neutrophil-lymphocyte ratio predicts disease severity and outcome after lower extremity procedures.
This study examined the association of neutrophil-lymphocyte ratio (NLR) and complications for patients undergoing interventions for peripheral artery disease (PAD) and other lower extremity conditions. NLR has been associated with higher mortality and other adverse outcomes for those with PAD. The study used inpatients undergoing lower extremity procedures (2008-2016) that were selected from the Cerner Health Facts database (Cerner Corporation, North Kansas City, Mo) using ICD-9 procedure codes. A total of 3687 patients were evaluated, with 2183 undergoing endovascular procedures and 1504 undergoing open procedures. White patients were likely to experience claudication but have less tissue loss. Open procedures had higher NLR rates than endovascular procedures. Preoperative high NLR was strongly associated with in-hospital deaths, cardiac complications, amputation, renal failure, respiratory complications, and prolonged length of stay. Postoperative high NLR values were also associated with more severe PAD.

Pre- and peri-operative factors associated with chronic critical illness in liver transplant recipients.
This study examined whether patients with end-stage liver failure undergoing liver transplant would be at high risk for developing chronic critical illness (CCI). They looked at pre- and perioperative factors associated with CCI. This retrospective cohort study was performed at a large academic transplant center and included all adult liver transplant patients from 2011 to 2017. CCI was defined as the need for mechanical ventilation for seven days or more post-transplant. Recipients who had re-transplantation, acute rejection, or who died during transplant surgery were excluded. They identified 382 transplant recipients, and out of that cohort 45 (11.8%) developed CCI. Eight independent factors were associated with CCI including previous liver transplant, acute renal failure, frailty, lower albumin level, higher international normalized ratio, need for mechanical ventilation and higher systolic pulmonary artery pressure. A higher pre-transplant Model for End-Stage Liver Disease (MELD) score was associated with protection against CCI.

Using cluster analysis to identify patient factors linked to differential functional gains after total knee arthroplasty.
This study used cluster analysis to identify patient factors linked to different outcomes following total knee arthroplasty (TKA). The study analyzed Short Form 36 Physical Component Score (PCS) trajectories of 656 patients at 3 time points over a 1-year period. The MultiExperiment View (MeV) built-in bootstrapping method was used to assess statistical significance of the clusters. They found two distinct clusters: Cluster 1 included 550 patients (84%) who demonstrated persistent improvement at 6 and 12 months. The remainder of patients consisted of Cluster 2 who demonstrated decline in PCS at 6 months but improved by 12 months. Cluster 1 was found to have higher baseline mental health scores, lower baseline PCS, and a significantly higher proportion of non-Hispanic Whites compared to Cluster 2.

Frequency and risk factors for prolonged opioid prescriptions after surgery for brachial plexus injury.
This study examined risk of prolonged opioid prescription use after surgery for brachial plexus injury (BPI). A cohort of BPI surgery patients was compared to a control group of non-BPI patients, matching for age, sex, and year. Pharmacy claims for prescriptions filled for opioids and neuropathic pain methods were examined 1 year before surgery to 180 days after surgery. The primary outcome studied was prolonged opioid prescription, which is defined as receiving a prescription 90 to 180 days after the surgery or randomly selected date of service for controls. Among BPI patients, a subgroup analysis was also performed on opioid-naïve patients between 30 days to 1 year before surgery. Among BPI surgery patients, 27.7% had prolonged opioid prescriptions, but only 10.8% of opioid-naïve patients had prolonged opioid prescriptions. The rate for controls was 0.11%. The rates of prolonged opioid prescriptions for BPI patients was higher than previous estimates among other surgical patients.

The association of preoperative cardiac stress testing with 30-day death and myocardial infarction among patients undergoing kidney transplantation.
This study examined whether the use of preoperative cardiac stress testing of patients undergoing kidney transplantation reduced 30-day- death and myocardial infarction post-transplantation. ESRD patients 40 years or older with primary Medicare insurance between 2006 and 2013 were identified using the United States Renal Data System. In a matched cohort of 17,304 patients, there was little difference in 30-day post-transplantation mortality and myocardial infarction between those receiving a stress test and those who did not.

Practice style variation in Medicaid and non-Medicaid children with complex chronic conditions undergoing surgery.
With differential payment between Medicaid and Non-Medicaid services, researchers asked whether style-of-practice differs between similar Medicaid and Non-Medicaid children with complex chronic conditions (CCCs) undergoing surgery. They found that treatment style differences between Medicaid and Non-Medicaid children were small, suggesting little disparity with in-hospital surgical care for patients with CCCs operated on within Children's Hospitals.

How often is sinus surgery performed for chronic rhinosinusitis with versus without nasal polyps?
The purpose of this study was to compare the rate of surgical interventions for chronic rhinosinusitis with nasal polyposis (CRSwNP) and chronic rhinosinusitis without nasal polyposis (CRSsNP). The investigators found that almost 30% of endoscopic sinus surgeries were performed for CRSwNP, and these cases were, on average, more extensive, used more OR time, and more often used image guidance than surgeries for CRSsNP.
