Association of county-level food deserts and food swamps on postoperative outcomes among patients undergoing colorectal surgery.

BACKGROUND: Although malnutrition has been linked to worse healthcare outcomes, the broader context of food environments has not been examined relative to surgical outcomes. We sought to define the impact of food environment on postoperative outcomes of patients undergoing resection for colorectal cancer (CRC). METHODS: Patients who underwent surgery for CRC between 2014 and 2020 were identified from the Medicare database. Patient-level data were linked to the United States Department of Agriculture data on food environment. Multivariable regression was used to examine the association between food environment and the likelihood of achieving a textbook outcome (TO). TO was defined as the absence of an extended length of stay (≥75th percentile), postoperative complications, readmission, and mortality within 90 days. RESULTS: A total of 260,813 patients from 3017 counties were included in the study. Patients from unhealthy food environments were more likely to be Black, have a higher Charlson Comorbidity Index, and reside in areas with higher social vulnerability (all P < .01). Patients residing in unhealthy food environments were less likely to achieve a TO than that of patients residing in the healthiest food environments (food swamp: 48.8% vs 52.4%; food desert: 47.9% vs 53.7%; P < .05). On multivariable analysis, individuals residing in the unhealthy food environments had lower odds of achieving a TO than those of patients living in the healthiest food environments (food swamp: OR, 0.86; 95% CI, 0.83-0.90; food desert: OR, 0.79; 95% CI, 0.76-0.82); P < .05). CONCLUSION: The surrounding food environment of patients may serve as a modifiable sociodemographic risk factor that contributes to disparities in postoperative CRC outcomes.

Inflammatory bowel disease-associated colorectal cancer negatively affects surgery outcomes and health care costs.

BACKGROUND: Inflammatory bowel disease may affect the pathogenesis and clinicopathologic course of colorectal cancer. We sought to characterize the impact of inflammatory bowel disease on outcomes after colectomy and/or proctectomy for a malignant indication. METHODS: Patients diagnosed with colorectal cancer as well as a pre-existing comorbid diagnosis of Crohn's disease or ulcerative colitis between 2018 and 2021 were identified from Medicare claims data. The postoperative textbook outcome was defined as the absence of complications, as well as no extended hospital stay, 90-day readmission, or mortality. Postdischarge disposition and expenditures were also examined. RESULTS: Among 191,684 patients with colorectal cancer, 4,770 (2.5%) had a pre-existing diagnosis of inflammatory bowel disease. Patients with inflammatory bowel disease-associated colorectal cancer were less likely to undergo surgical resection (no inflammatory bowel disease: 47.6% vs inflammatory bowel disease: 42.1%; P < .001). Among patients who did undergo colorectal surgery, individuals with inflammatory bowel disease were less likely to achieve a textbook outcome (odds ratio 0.64 [95% confidence interval 0.58-0.70]). In particular, patients with inflammatory bowel disease had higher odds of postoperative complications (odds ratio 1.24 [1.12-1.38]), extended hospital stay (odds ratio 1.41 [1.27-1.58]), and readmission within 90 days (odds ratio 1.56 [1.42-1.72]) (all P < .05). Patients with inflammatory bowel disease-associated colorectal cancer were less likely to be discharged to their home under independent care (odds ratio 0.77 [0.68-0.87]) and had 12.2% higher expenditures, which correlated with whether the patient had a postoperative textbook outcome. CONCLUSION: One in 40 patients with colorectal cancer had concomitant inflammatory bowel disease. Inflammatory bowel disease was associated with a lower probability of achieving ideal postoperative outcomes, higher postdischarge expenditure, as well as worse long-term survival after colorectal cancer resection.

Gender bias in colorectal surgery fellowship letters of recommendation.

BACKGROUND: As leaders strive to create equitable surgical pipelines, one process under scrutiny is letters of recommendation (LORs). We sought to review the Colon and Rectal Surgery (CRS) Resident Candidate Assessment questionnaire and LORs for gendered differences. METHODS: This retrospective observational study of letters of recommendation to CRS fellowship during the 2018-2019 application cycle utilized linguistic Inquiry and Word Count (LIWC2015) software to assess letter length and themes comparing differences by applicant and referee gender. RESULTS: 103 applicants (35 â€‹% women) with 363 LORs (16 â€‹% written by women) were included. Short answer responses were longer for women applicants, while LORs were longer for men applicants (368 vs 325 words p â€‹= â€‹0.03). Men applicants' strengths had more technical skill descriptors, while women applicants' strengths had more emotional language and cognitive and perceptual words. CONCLUSIONS: This study found significant differences between LORs written for CRS fellowship applicants based on gender.

UNOS Decisions Impact Data Integrity of the OPTN Data Registry.

BACKGROUND: The Organ Procurement Transplant Network (OPTN)/United Network for Organ Sharing (UNOS) registry is an important national registry in the field of solid organ transplantation. Data collected are mission critical, given its role in organ allocation prioritization, program performance monitoring by both the OPTN and the Centers for Medicare & Medicaid Services, and countless observational analyses that helped to move the field forward. Despite the multifaceted importance of the OPTN/UNOS database, there are clear indications that investments in the database to ensure the quality and reliability of the data have been lacking. METHODS: This analysis outlines 2 examples: (1) primary diagnosis for patients who are receiving a second transplant and (2) reporting peripheral vascular disease in kidney transplantation to illustrate the extensive challenges facing the veracity and integrity of the OPTN/UNOS database today. RESULTS: Despite guidance that repeat kidney transplant patients should be coded as "retransplant/graft failure" rather than their native kidney disease, only 59% of new incident patients are coded in this manner. Peripheral vascular disease prevalence more than doubled in a 20-y span when the variable became associated with risk adjustment. CONCLUSIONS: This article summarizes critical gaps in the OPTN/UNOS database, and we bring forward ideas and proposals for consideration as a path toward improvement.

Assessment of performance of stratum-specific likelihood ratios of the aldosteronoma resolution score for predicting hypertension cure after adrenalectomy for primary aldosteronism: a systematic review and meta-analysis.

The Aldosteronoma Resolution Score (ARS) is the most studied scoring system for predicting the high likelihood of hypertension cure after adrenalectomy for unilateral primary aldosteronism (PA). However, the ARS's accuracy in PA patients worldwide is uncertain. We aimed to perform a meta-analysis of the accuracy, discrimination, and calibration of the ARS using stratum-specific likelihood ratios (SSLR) by organizing available data from cohort studies. We searched PubMed, Embase (Ovid), the Cochrane CENTRAL, Web of Science to November 2021 according to PRISMA statement. The quality assessment used adapted TRIPOD and PROBAST criteria. Thirteen studies comprising 2158 PA patients from North America (43%), Europe (32%), Asia (22%), and other continents, were included. The pooled estimate of the area under the receiver operating characteristic curve for all studies was 0.77 (95% CI: 0.73-0.81), and the ratio of the observed to expected complete resolution of hypertension (CRH) for all studies was 0.9 (95% CI: 0.8-1.0). The summary estimates of the SSLR for all studies were 0.31, 0.89, and 3.1, for the low (ARS 0-1), medium (ARS 2-3), and high-likelihood group (ARS 4-5) of CRH, respectively. However, substantial heterogeneity existed among studies. Follow-up period, and adrenalectomy AVS (adrenal vein sampling)-guided served as potential sources of heterogeneity for quantitative studies, which were measurement and reference standard for qualitative studies selection. In conclusion, in patients with unilateral PA, the ARS is currently an accurate prediction tool, the easiest and cheapest, for identifying long-term high likelihood of CRH after adrenalectomy, particularly when the adrenalectomy is AVS-guided.

Phytocompounds targeting epigenetic modulations: an assessment in cancer.

For centuries, plants have been serving as sources of potential therapeutic agents. In recent years, there has been a growing interest in investigating the effects of plant-derived compounds on epigenetic processes, a novel and captivating Frontier in the field of epigenetics research. Epigenetic changes encompass modifications to DNA, histones, and microRNAs that can influence gene expression. Aberrant epigenetic changes can perturb key cellular processes, including cell cycle control, intercellular communication, DNA repair, inflammation, stress response, and apoptosis. Such disruptions can contribute to cancer development by altering the expression of genes involved in tumorigenesis. However, these modifications are reversible, offering a unique avenue for therapeutic intervention. Plant secondary compounds, including terpenes, phenolics, terpenoids, and sulfur-containing compounds are widely found in grains, vegetables, spices, fruits, and medicinal plants. Numerous plant-derived compounds have demonstrated the potential to target these abnormal epigenetic modifications, including apigenin (histone acetylation), berberine (DNA methylation), curcumin (histone acetylation and epi-miRs), genistein (histone acetylation and DNA methylation), lycopene (epi-miRs), quercetin (DNA methylation and epi-miRs), etc. This comprehensive review highlights these abnormal epigenetic alterations and discusses the promising efficacy of plant-derived compounds in mitigating these deleterious epigenetic signatures in human cancer. Furthermore, it addresses ongoing clinical investigations to evaluate the therapeutic potential of these phytocompounds in cancer treatment, along with their limitations and challenges.

The difference between cystatin C- and creatinine-based assessment of kidney function in acute heart failure.

AIMS: Acute heart failure (HF) is associated with muscle mass loss, potentially leading to overestimation of kidney function using serum creatinine-based estimated glomerular filtration rate (eGFRsCr ). Cystatin C-based eGFR (eGFRCysC ) is less muscle mass dependent. Changes in the difference between eGFRCysC and eGFRsCr may reflect muscle mass loss. We investigated the difference between eGFRCysC and eGFRsCr and its association with clinical outcomes in acute HF patients. METHODS AND RESULTS: A post hoc analysis was performed in 841 patients enrolled in three trials: Diuretic Optimization Strategy Evaluation (DOSE), Renal Optimization Strategies Evaluation (ROSE), and Cardiorenal Rescue Study in Acute Decompensated Heart Failure (CARRESS-HF). Intra-individual differences between eGFRs (eGFRdiff ) were calculated as eGFRCysC -eGFRsCr at serial time points during HF admission. We investigated associations of (i) change in eGFRdiff between baseline and day 3 or 4 with readmission-free survival up to day 60; (ii) index hospitalization length of stay (LOS) and readmission with eGFRdiff at day 60. eGFRCysC reclassified 40% of samples to more advanced kidney dysfunction. Median eGFRdiff was -4 [-11 to 1.5] mL/min/1.73 m2 at baseline, became more negative during admission and remained significantly different at day 60. The change in eGFRdiff between baseline and day 3 or 4 was associated with readmission-free survival (adjusted hazard ratio per standard deviation decrease in eGFRdiff : 1.14, P = 0.035). Longer index hospitalization LOS and readmission were associated with more negative eGFRdiff at day 60 (both P ≤ 0.026 in adjusted models). CONCLUSIONS: In acute HF, a marked difference between eGFRCysC and eGFRsCr is present at baseline, becomes more pronounced during hospitalization, and is sustained at 60 day follow-up. The change in eGFRdiff during HF admission and eGFRdiff at day 60 are associated with clinical outcomes.

Clinical Assessment of Continuous Hemodialysis with the Medium Cutoff EMiC®2 Membrane in Patients with Septic Shock.

INTRODUCTION: At the time of renal replacement therapy, approximately 20% of critically ill patients have septic shock. In this study, medium cutoff (MCO) continuous venovenous hemodialysis (CVVHD) was compared to high-flux membrane continuous venovenous hemodiafiltration (CVVHDF) in terms of hemodynamic improvement, efficiency, middle molecule removal, and inflammatory system activation. METHODS: This is a monocenter crossover randomized study. Between December 31, 2017, and December 31, 2019, 20 patients with septic shock and stage 3 acute kidney injury (AKI) admitted to 2 Italian ICUs were enrolled. All patients underwent CVVHD with Ultraflux® EMiC®2 and CVVHDF with AV1000S® without washout. Each treatment lasted 24 h. RESULTS: Compared to AV1000S®-CVVHDF, EMIC®2-CVVHD normalized cardiac index (ß = -0.64; p = 0.02) and heart rate (ß = 5.72; p = 0.01). Interleukin-8 and myeloperoxidase removal were greater with AV1000S®-CVVHDF than with EMiC®2-CVVHD (ß = 0.35; p < 0.001; ß = 0.43; p = 0.03, respectively). Leukocytosis improved over 24 h in EMiC®2-CVVHD-treated patients (ß = 4.13; p = 0.03), whereas procalcitonin levels decreased regardless of the modality (ß = 0.89; p = 0.01) over a 48-h treatment period. Reduction rates, instantaneous plasmatic clearance of urea, creatinine, and ß2-microglobulin were similar across modalities. ß2-Microglobulin removal efficacy was greater in the EMiC®2 group (ß = 0-2.88; p = 0.002), while albumin levels did not differ. Albumin was undetectable in the effluent in both treatments. DISCUSSION: In patients with septic shock and severe AKI, the efficacy of uremic toxin removal was comparable between MCO-CVVHD and CVVHDF. Further, MCO-CVVHD was associated with improved hemodynamics. Fraction of filtration and transmembrane pressure reduction and the maintenance of equal efficacy might be the key features of CVVHD with MCO membranes in critically ill patients.

Risk Assessment of Ambient Air Pollutants and Health Impact around Fuel Stations in Urban Cities of KSA.

BACKGROUND: In Saudi Arabia, fuel dispensing facilities commonly present around the residential places, educational institutions, and various health care facilities. Fuel pollutants such as benzene, toluene, and xylenes (BTX) and its alkyl derivatives are harmful to human health because of their toxic, mutagenic, or carcinogenic properties. The aim of this study was to determine the BTX concentration levels of common pollutants in and around fuel stations and their harmful health effects in the urban cites of KSA. METHODS: Forty fuel dispensing facilities were randomly selected on the basis of three different areas: residential, traffic intersection, and petrol pump locations (refueling stations). Portable ambient analyzer was used for measuring BTX concentration. t-test was applied to determine the difference between these different areas. RESULTS: All mean concentration values of pollutants such as BTX around residential, traffic intersection, and fuel stations are exceeding the limits of air quality standards values (P < 0.01). The mean levels of benzene are 10.3 and 11.07 ppm in Dammam and Khobar, respectively, and they exceed the reference level of 0.5 ppm. Hazard quotient was more than >1, which shows that carcinogenic probability has increased those who were living and working near fuel stations. CONCLUSIONS: The results found that the high concentration of pollutants (BTX) is in the environment around fuel stations. The environmental contamination associated with BTX in petrol fuel stations impulses the necessity of preventive programs to reduce the further air quality deterioration and reduce the harmful health effects.

Phytocompounds Targeting Metabolic Reprogramming in Cancer: An Assessment of Role, Mechanisms, Pathways, and Therapeutic Relevance.

The metabolism of cancer is remarkably different from that of normal cells and confers a variety of benefits, including the promotion of other cancer hallmarks. As the rewired metabolism is a near-universal property of cancer cells, efforts are underway to exploit metabolic vulnerabilities for therapeutic benefits. In the continued search for safer and effective ways of cancer treatment, structurally diverse plant-based compounds have gained substantial attention. Here, we present an extensive assessment of the role of phytocompounds in modulating cancer metabolism and attempt to make a case for the use of plant-based compounds in targeting metabolic vulnerabilities of cancer. We discuss the pharmacological interactions of phytocompounds with major metabolic pathways and evaluate the role of phytocompounds in the regulation of growth signaling and transcriptional programs involved in the metabolic transformation of cancer. Lastly, we examine the potential of these compounds in the clinical management of cancer along with limitations and challenges.

Patients with High Priority for Kidney Transplant Who Are Not Given Expedited Placement on the Transplant Waiting List Represent Lost Opportunities.

BACKGROUND: Kidney transplantation is associated with the best outcomes for most patients with ESKD. The national Kidney Allocation System prioritizes patients with Estimated Post-Transplant Survival (EPTS) scores in the top 20% for expedited access to optimal deceased donor kidneys. METHODS: We studied adults aged ≥18 years in the United States Renal Data System with top 20% EPTS scores who had been preemptively waitlisted or initiated dialysis in 2015-2017. We evaluated time to waitlist placement, transplantation, and mortality with unadjusted and multivariable survival models. RESULTS: Of 42,445 patients with top 20% EPTS scores (mean age, 38.0 years; 57% male; 59% White patients, and 31% Black patients), 7922 were preemptively waitlisted. Among 34,523 patients initiating dialysis, the 3-year cumulative waitlist placement incidence was 37%. Numerous factors independently associated with waitlisting included race, income, and having noncommercial insurance. For example, waitlisting was less likely for Black versus White patients, and for patients in the lowest-income neighborhoods versus those in the highest-income neighborhoods. Among patients initiating dialysis, 61% lost their top 20% EPTS status within 30 months versus 18% of patients who were preemptively listed. The 3-year incidence of deceased and living donor transplantation was 5% and 6%, respectively, for patients who initiated dialysis and 26% and 44%, respectively, for patients who were preemptively listed. CONCLUSIONS: Many patients with ESKDqualifying with top 20% EPTS status are not placed on the transplant waiting list in a timely manner, with significant variation on the basis of demographic and social factors. Patients who are preemptively listed are more likely to receive benefits of top 20% EPTS status. Efforts to expedite care for qualifying candidates are needed, and automated transplant referral for patients with the best prognoses should be considered.

Assessment of Cancer Center Variation in Textbook Oncologic Outcomes Following Colectomy for Adenocarcinoma.

BACKGROUND: Traditional metrics may inadequately represent rates of attaining optimal oncologic care. We evaluated a composite "textbook oncologic outcome" (TOO) to assess the incidence of achieving an "optimal" clinical result after colon adenocarcinoma (CA) resection. METHODS: The National Cancer Database (NCDB) was queried to identify patients undergoing colectomy for non-metastatic CA between 2010 and 2015. TOO was defined as a margin negative resection with an AJCC compliant lymph node evaluation, no prolonged length of stay (LOS) or 30-day readmission/mortality, as well as receipt of stage appropriate adjuvant chemotherapy. RESULTS: Among 170,120 patients who underwent colectomy at 1315 hospitals, 93,204 (54.8%) achieved TOO with large variations observed among facilities. While certain factors were achieved nearly universally (R0 margin, 95.6%; no 30-day mortality, 97.2%), avoidance of prolonged LOS (77.3%) and appropriate adjuvant chemotherapy (83.0%) were achieved less consistently. On multivariable analysis, Black race/ethnicity (OR 0.82, 95% CI 0.80-0.85), Medicaid insurance (OR 0.64, 0.61-0.68), and low-volume facility (< 50/year) (OR 0.83, 0.77-0.89) were associated with decreased likelihood of TOO. Achievement of TOO was associated with improved long-term survival (HR 0.45; 95% CI 0.44-0.46). CONCLUSIONS: Roughly one-half of patients undergoing resection of CA achieved an optimal clinical outcome. TOO may be a more useful quality metric to assess patient-centric composite outcomes following surgical procedures.

Cystatin C- Versus Creatinine-Based Assessment of Renal Function and Prediction of Early Outcomes Among Patients With a Left Ventricular Assist Device.

BACKGROUND: Estimated glomerular filtration rate (eGFR) based on serum creatinine (sCr) improves early after left ventricular assist device (LVAD) implantation but subsequently declines. Although sCr is a commonly accepted clinical standard, cystatin C (CysC) has shown superiority in assessment of renal function in disease states characterized by muscle wasting. Among patients with an LVAD, we aimed to (1) longitudinally compare CysC-eGFR and sCr-eGFR, (2) assess their predictive value for early postoperative outcomes, and (3) investigate mechanisms which might explain potential discrepancies. METHODS: A prospective cohort (n=116) with CysC and sCr concurrently measured at serial time points, and a retrospective cohort (n=91) with chest computed tomography performed within 40 days post-LVAD were studied. In the prospective cohort, the primary end point was a composite of in-hospital mortality, renal replacement therapy, or severe right ventricular failure. In the retrospective cohort, muscle mass was estimated using pectoralis muscle area indexed to body surface area (pectoralis muscle index). RESULTS: In the prospective cohort, sCr-eGFR significantly improved early post-LVAD and subsequently declined, whereas CysC-eGFR remained stable. CysC-eGFR but not sCr-eGFR predicted the primary end point: odds ratio per 5 mL/(min·1.73 m2) decrease 1.16 (1.02-1.31) versus 0.99 (0.94-1.05). In retrospective cohort, for every 5 days post-LVAD, a 6% decrease in pectoralis muscle index was observed (95% CI, 2%-9%, P=0.003). After adjusting for time on LVAD, for every 1 cm2/m2 decrease in pectoralis muscle index, there was a 4% decrease in 30-day post-LVAD sCr (95% CI, 1%-6%, P=0.004). CONCLUSIONS: Initial improvement in sCr-eGFR is likely due to muscle wasting following LVAD surgery. CysC may improve assessment of renal function and prediction of early postoperative outcomes in patients with an LVAD.

A Donor Utilization Index to Assess the Utilization and Discard of Deceased Donor Kidneys Perceived as High Risk.

BACKGROUND AND OBJECTIVES: An increasing number of patients on the waitlist for a kidney transplant indicates a need to effectively utilize as many deceased donor kidneys as possible while ensuring acceptable outcomes. Assessing regional and center-level organ utilization with regards to discard can reveal regional variation in suboptimal deceased donor kidney acceptance patterns stemming from perceptions of risk. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We created a weighted donor utilization index from a logistic regression model using high-risk donor characteristics and discard rates from 113,640 deceased donor kidneys procured for transplant from 2010 to 2016, and used it to examine deceased donor kidney utilization in 182 adult transplant centers with >15 annual deceased donor kidney transplants. Linear regression and correlation were used to analyze differences in donor utilization indexes. RESULTS: The donor utilization index was found to significantly vary by Organ Procurement and Transplantation Network region (P<0.001), revealing geographic trends in kidney utilization. When investigating reasons for this disparity, there was no significant correlation between center volume and donor utilization index, but the percentage of deceased donor kidneys imported from other regions was significantly associated with donor utilization for all centers (rho=0.39; P<0.001). This correlation was found to be particularly strong for region 4 (rho=0.83; P=0.001) and region 9 (rho=0.82; P=0.001). Additionally, 25th percentile time to transplant was weakly associated with the donor utilization index (R2=0.15; P=0.03). CONCLUSIONS: There is marked center-level variation in the use of deceased donor kidneys with less desirable characteristics both within and between regions. Broader utilization was significantly associated with shorter time to transplantation.

Defining payments associated with the treatment of colorectal cancer.

BACKGROUND: While bundled payments aim to reduce variations in health care spending across the continuum of care, data reporting on variations in payments for privately insured patients undergoing treatment for colon cancer (CC) are lacking. The current study sought to characterize variations in payments received for the treatment of CC using a cohort of commercially insured patients. METHODS: Patients who underwent a colectomy for CC were identified using the MarketScan Database for 2010-2014. Multivariable regression analysis was used to calculate and compare risk-adjusted payments between patients. RESULTS: A total of 18,337 patients were identified who met inclusion criteria. The median risk-adjusted payment for surgery was $26,408 (IQR: $19,193-$38,037) ranging from $19,762 (IQR: $15,595-$25,636) among patients in the lowest quartile of payments to $33,809 (IQR: $24,783-$48,254) for patients in the highest (+△71.1%). The median risk-adjusted payment for chemotherapy was $70,090 (IQR: $57,813-$83,216); compared with patients in the lowest quartile of payments, payments associated with chemotherapy were 40.4% higher among patients in the highest quartile of payments (Q1 versus Q4: $56,827 [IQR: 49,173-65,353] versus $79,801 [IQR: 67,270-90,999]). When stratified by treatment type, patients in the highest two quartiles of risk-adjusted payments accounted for a total of 58.5% of all payments, whereas patients in the lower two quartiles of risk-adjusted payments accounted for only 41.5% of all payments. A younger patient age, increasing patient comorbidity and undergoing an open operation were associated with higher overall payments. CONCLUSIONS: Wide variations in payments exist for the treatment for colon cancer. Episode-based bundle payments for surgery and chemotherapy may differentially impact reimbursement for CC.

Thromboelastography--does it impact blood component transfusion in pediatric heart surgery?

BACKGROUND: The administration of blood products during pediatric cardiac surgery is common. We sought to determine if thromboelastography (TEG) is a cost-effective tool to reduce blood product transfusion in open pediatric cardiac surgery. MATERIALS AND METHODS: A retrospective case-control study was undertaken for 150 pediatric cardiac patients requiring cardiopulmonary bypass from January 2010-May 2012, in a University-affiliated pediatric hospital. Fifty sequential patients operated on when TEG was used were compared with 100 control patients before TEG availability. Groups were matched 2:1 for age and risk adjustment for congenital heart surgery score. Blood product utilization was compared between groups, as were outcomes metrics such as postoperative complications, length of stay, and hospital costs of transfusions. RESULTS: Demographic variables, risk adjustment for congenital heart surgery score classifications, and cardiopulmonary bypass times were similar between groups. Red cell and plasma transfusion were comparable between groups. TEG patients saw a substantial reduction in the administration of platelet (1 versus 2.2 U; P < 0.0001) and cryoprecipitate (0.7 versus 1.7 U; P < 0.0001) transfusions. A greater than 50% reductions in hospital costs of platelet ($595 versus $1309) and cryoprecipitate ($39 versus $94) transfusions were observed in the TEG group. Mortality, length of stay, ventilator requirements, postoperative bleeding, and thrombotic events were equivalent. CONCLUSIONS: Intraoperative TEG use reduced platelet and cryoprecipitate transfusions without an increase in postoperative complications. TEG is a cost-effective method to direct blood product replacement.
