Short-term risk of performing concurrent procedures with hepatic artery infusion pump placement.
This study’s objective was to characterize the short-term outcomes of concurrent surgery with hepatic artery infusion pump (HAIP) placement using data from the 2005-2017 ACS NSQIP dataset. Findings showed that HAIP placement is not associated with additional morbidity when performed with hepatic and/or colorectal surgery. Decisions regarding HAIP placement should consider the risks of concurrent operations as well as patient- and disease-specific factors.

Sleep disturbances after pediatric traumatic brain injury: a systematic review of prevalence, risk factors, and association with recovery.
This is a systematic review to quantify sleep wake disturbances (SWD) after pediatric traumatic brain injury (TBI). These SWD can place children at risk for worse outcomes since sleep is needed for brain development and healing after injury. They also evaluated interventions for SWD and the association between SWD and other post-traumatic outcomes. Literature was searched from 1999-2019 evaluating sleep or fatigue in children hospitalized for TBI. Two independent reviewers assessed quality of the studies using the Newcastle-Ottowa Score for observational studies. Out of 966 identified articles, 126 full text articles were reviewed and 24 studies were included. Studies showed at least 20% of children with TBI had some degree of SWD including trouble falling or staying asleep, fatigue, daytime fatigue, and nightmares. SWD was negatively correlated with cognitive, behavioral, and quality of life outcomes. There was moderate-high risk of bias for all studies due to small sample size and lack of validated or objective SWD measures.

Risk of bleeding with exposure to warfarin and nonsteroidal anti-inflammatory drugs: a systematic review and meta-analysis.
Warfarin use can trigger the occurrence of bleeding independently or as a result of a drug-drug interaction when used in combination with nonsteroidal anti-inflammatory drugs (NSAIDs). This article examines the risk of bleeding in individuals exposed to concomitant warfarin and NSAID compared with those taking warfarin alone. The investigators concluded that risk of bleeding was significantly increased among persons taking warfarin and a NSAID or COX-2 inhibitor together as compared with taking warfarin alone.

Post-operative complications and readmissions associated with smoking following bariatric surgery.
The link between smoking and poor postoperative outcomes is well established. Despite this, current smokers are still offered bariatric surgery. In this study, the investigators describe the risk of postoperative 30-day complications and readmission following laparoscopic sleeve gastrectomy and laparoscopic Roux-En-Y gastric bypass in smokers. The investigators concluded that smokers undergoing bariatric surgery experienced significantly worse 30-day outcomes when compared with non-smokers.

Frailty as a predictor of death or new disability after surgery: a prospective cohort study.
The purpose of this study was to compare the accuracy of the modified Fried Index (mFI) and the Clinical Frailty Scale (CFS) to predict death or patient-reported new disability 90 days after major elective surgery. Results showed that older people with frailty are significantly more likely to die or experience a new patient-reported disability after surgery and that although accuracy was similar, the CFS, compared to the mFI, was easier to use and feasibility was higher.

Hospital experience predicts outcomes after high-risk geriatric surgery.
This study examined if there an association between a hospital’s annual volume of high-risk geriatric surgery and their risk of inpatient mortality, postoperative length of stay, and discharge to nursing facility. Using the 2014 National Inpatient Sample, older adults were identified who had undergone high-risk geriatric surgery. There were an estimated 514,950 hospital encounters at 3,115 hospitals undergoing surgery. A higher proportion of high-risk geriatric surgery patients was associated with decreased mortality and shorter postoperative length of stay. Higher volume hospitals were not associated with mortality but was associated with longer length of stay and decreased discharge to nursing facilities.

Centralization of high-risk cancer surgery within existing hospital systems.
Centralization is often proposed as a strategy to improve the quality of certain high-risk health care services. In this study, the investigators evaluated the extent to which existing hospital systems centralize high-risk cancer surgery and whether centralization is associated with short-term clinical outcomes. The investigators concluded that greater centralization of complex cancer surgery within existing hospital systems was associated with better outcomes.

Discharge disposition to skilled nursing facility after emergent general surgery predicts a poor prognosis.
Emergency general surgery can have a profound impact on the functional status of even previously independent patients. In this study, the investigators examined the role and influence of discharging a patient to a skilled nursing facility. They concluded that after accounting for patient severity and perioperative course, discharge to a skilled nursing facility was an independent risk factor for death, readmission, and postdischarge complications.

Cohort study of risk factors for 30-day readmission after abdominal aortic aneurysm repair.
This retrospective cohort study examined 30-day readmission rates for patients who had abdominal aortic aneurysm (AAA) repair comparing two different procedures,. The cohort was selected from inpatients (2009-2016) who had undergone elective AAA repair using the multicenter Cerner Health Facts(R) database and were identified ICD-9 procedure codes. The two procedures compared were 3,101 endovascular aneurysm repairs (EVAR) and 1,622 open procedures. Patients who had EVAR were less likely to be readmitted. Risk factors for readmission included surgical site infection, age, receipt of bronchodilators or steroids, serum potassium > 5.2 mEq/L, and higher Charlson co-morbidity scores. The most common infections causing readmission were pneumonia and urinary tract infection after EVAR.

Simplified risk prediction indices do not accurately predict 30-day death or readmission after discharge following colorectal surgery.
This study examined the performance of widely used risk prediction indices to predict 30-day death or readmission after discharge following colorectal surgery. The study used a retrospective split-sample cohort of patients discharged after colorectal surgery from inpatient databases of HCUP for the states of New York, California, and Florida from 2006-2014. The commonly used risk prediction model LACE (length of stay, acute admissions, Charlson comorbidity index score, and emergency department visits) was compared with the real outcomes of death or readmission within 30 days after discharge with the cohort. Results showed a poor model fit with LACE and the researchers recommended a better model be developed.

Retooling of paper-based outcome measures to electronic format: comparison of the NY State public risk model and EHR-derived risk models for CABG mortality.
This study assessed the feasibility of retooling the paper-based New York State coronary artery bypass graft (CABG) surgery statistical model for mortality and readmission into a model for electronic health records (EHRs). Researchers found that only 6 data elements could be extracted from the EHR, and outlier hospitals differed for readmission but was usable for mortality. They concluded that the EHR model was inferior to the NYS model, and that simplifying the EHR risk model couldn’t capture most of the risk factors in the NYS model.

Patient phenotypes, cardiovascular risk, and ezetimibe treatment in patients after acute coronary syndromes (from IMPROVE-IT).
The authors of this article performed a hierarchical cluster analysis to identify acute coronary syndrome (ACS) patients at high risk for adverse clinical events. Post-ACS patients were randomized to ezetimibe+simvastatin or placebo+simvastatin. Ezetimibe's impact on outcomes across clusters; the ability of the cluster analysis to discriminate for outcomes was compared with the Global Registry of Acute Coronary Events (GRACE) score. Outcomes included cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, hospitalization for unstable angina, or coronary revascularization at least 30 days after randomization. Compared with GRACE, cluster analysis did not provide superior outcome discrimination. Consistent ezetimibe treatment effect was identified across clusters. The authors conclude that cluster analysis identified significant difference in risk of outcomes across cluster groups.

Psychosocial risks are independently associated with cancer surgery outcomes in medically comorbid patients.
The purpose of this prospective observational study was to assess the association of preoperative psychosocial risk factors and 30-day complications following cancer surgery. The investigators demonstrated a more than threefold odds of a complication in medically comorbid patients with multiple psychosocial risks. They suggest that their findings support the use of psychosocial risks in preoperative assessment and consideration for inclusion in preoperative optimization efforts.

Gender disparities in trauma care: how sex determines treatment, behavior, and outcome.
This study used US and European trauma database statistics, including the National Trauma Databank, to examine sex disparities in trauma care. Their findings indicate that sex differences in risk-taking behaviors that lead to traumatic injury have been associated with males, with female menstrual cycle timing, and with cortisol levels. Differences in access to services at trauma centers, including triage or transfer and level of medical attention are associated with sex as well race, rural or urban location, and insurance status. Outcomes, such as in-hospital mortality, multiple organ failure, pneumonia, and sepsis are associated with sex disparities in the general trauma patient; outcomes after general trauma and specifically traumatic brain injury show mixed results.

Editor's choice - comparison of outcomes after open surgical and endovascular lower extremity revascularisation among end stage renal disease patients on dialysis.
This study compared outcomes of different revascularization surgeries among end stage renal disease (ESRD) patients with peripheral arterial disease (PAD). There is a high risk of complications for this surgery. Outcomes of endovascular revascularization (ER) and open surgical revascularisation (OSR) were compared. Outcomes measured included mortality and major amputation. There is a lower mortality risk for ER versus OSR. OSR has better 30-day limb salvage although there are similar long-term outcomes.
