RESUMO
Sepsis causes 270,000 deaths and costs $38 billion annually in the United States. Most cases of sepsis present in the emergency department (ED), where rapid diagnosis remains challenging. The IntelliSep Index (ISI) is a novel diagnostic test that analyzes characteristics of WBC structure and provides a reliable early signal for sepsis. This study performs a cost-consequence analysis of the ISI relative to procalcitonin for early sepsis diagnosis in the ED. PERSPECTIVE: U.S. healthcare system. SETTING: Community hospital ED. METHODS: A decision tree analysis was performed comparing ISI with procalcitonin. Model parameters included prevalence of sepsis, sensitivity and specificity of diagnostic tests (both ISI and procalcitonin), costs of hospitalization, and mortality rate stratified by diagnostic test result. Mortality and prevalence of sepsis were estimated from best available literature. Costs were estimated based on an analysis of a large, national discharge dataset, and adjusted to 2018 U.S. dollars. Outcomes included expected costs and survival. RESULTS: Assuming a confirmed sepsis prevalence of 16.9% (adjudicated to Sepsis-3), the ISI strategy had an expected cost per patient of $3,849 and expected survival rate of 95.08%, whereas the procalcitonin strategy had an expected cost of $4,656 per patient and an expected survival of 94.98%. ISI was both less costly and more effective than procalcitonin, primarily because of fewer false-negative results. These results were robust in sensitivity analyses. CONCLUSIONS: ISI was both less costly and more effective in preventing mortality than procalcitonin, primarily because of fewer false-negative results. The ISI may provide health systems with a higher-value diagnostic test in ED sepsis evaluation. Additional work is needed to validate these results in clinical practice.
RESUMO
Do-not-resuscitate (DNR) orders should preclude the use of cardiopulmonary resuscitation and may be associated with patient outcomes for patients hospitalized with heart failure (HF). This study examined the association between DNR and costs, mortality, and length of stay. The study cohort was a national sample of 700 922 hospital admissions of patients aged >65 with a primary diagnosis of HF. Elderly HF patients who died with a DNR had cost-savings of $5640 ( P < 0.001). Patients with a DNR order were 8.9% points more likely to die before discharge than patients without ( P < 0.001), and patients who died with a DNR had a significantly shorter hospital stay by 1.51 days ( P < 0.001). DNR orders among elderly patients with HF are associated with cost-savings, as well as a higher mortality and shorter length of stay. In addition to primary benefits, advance care planning may aid in containing costs of care at end of life for HF.

BACKGROUND: The risk of instability, dislocation, and revision following total hip arthroplasty (THA) is increased in patients with abnormal spinopelvic mobility. Seated and standing lateral lumbar spine imaging can identify patients with stiff/hypermobile spine (SHS) to guide interventions such as changes in acetabular cup placement or use of a dual-mobility hip construct aimed at reducing dislocation risk. METHODS: A Markov decision model was created to compare routine preoperative spinal imaging (PSI) to no screening in patients with and without SHS. Screened patients with SHS were assumed to receive dual-mobility hardware while those without SHS and nonscreened patients were assumed to receive conventional THA. Cost-effectiveness was determined by estimating the incremental cost-effectiveness ratio. Effectiveness measured as quality-adjusted life years (QALYs), with $100,000 per additional QALY as the threshold for cost-effectiveness. Sensitivity analyses were performed to determine the robustness of the base-case result. RESULTS: The screening strategy with PSI had a lifetime cost of $12,515 and QALY gains of 16.91 compared with no-screening ($13,331 and 16.77). The PSI strategy reached cost-effectiveness at 5 years and was dominant (ie, less costly and more effective) at 11 years following THA. In sensitivity analyses, PSI remained the dominant strategy if prevalence of SHS was >1.9%, the cost of PSI was <$925, and the cost of dual-mobility hardware exceeded the cost of conventional hardware by <$2850. CONCLUSION: Screening patients for SHS prior to THA with PSI is both less costly and more effective and should be considered as part of standard presurgical workup.

PURPOSE: With the introduction of the Oncology Care Model and plans for the transition to Oncology Care First, alternative payment models (APMs) are an increasingly important piece of the oncology care landscape. Evidence is mixed on the Oncology Care Model's impact on utilization and costs, but as policymakers consider expansion of similar models, it is critical to understand the characteristics of hospitals that may be differentially affected. METHODS: We used 2007-2016 SEER-Medicare data to identify patients with breast and prostate cancer receiving chemotherapy, endocrine therapy (breast), or androgen deprivation therapy (prostate). For each hospital, we calculated 6-month expected mortality, emergency department (ED) visits, inpatient admissions, and costs, all commonly collected APM outcomes. After calculating observed-to-expected rates for each outcome by hospital, we estimated the association between observed-to-expected rates and characteristics of each hospital to understand hospital characteristics that might be associated with higher- or lower-than-expected rates of each outcome. RESULTS: Hospitals with > 15% rural patients had significantly higher-than-expected mortality (0.31 points higher, P < .001) and ED visit rates (0.10 points higher, P = .029) as well as significantly lower costs (0.06 points lower, P = .004). Hospitals unaffiliated with a medical school also experienced significantly higher-than-expected mortality and ED visits. Hospitals eligible for disproportionate share hospital payment experienced significantly higher ED visits but lower costs. For-profit hospitals experienced higher-than-expected mortality. CONCLUSION: Rural hospitals and those unaffiliated with a medical school may require special consideration as APMs expand in oncology care. Designated cancer centers and larger hospitals may be advantaged.

Renal dysfunction is associated with poor long-term outcomes after liver transplantation. We examined the renal sparing effect of everolimus (EVR) compared to standard calcineurin inhibitor (CNI) immunosuppression with direct measurements of renal function over 24 months. METHODS: This was a prospective, randomized, open-label trial comparing EVR and mycophenolic acid (MPA) with CNI and MPA immunosuppression. An Investigational New Drug Application (IND # 113882) was obtained with the Food and Drug Administration as EVR is only approved for use with low-dose tacrolimus. Serum creatinine, 24-hour urine creatinine clearance, iothalamate clearance, Cockcroft-Gault creatinine clearance (CrCl), and Modification of Diet in Renal Disease estimated glomerular filtration rate were prospectively measured at 4 study visits. Nonparametric statistical tests were used for analyses, including the Mann-Whitney U test for continuous outcomes and Pearson's chi-square test for binary outcomes. Effect size was measured using Cohen's d. Patients also completed quality of life surveys using the FACT-Hep instrument at each study visit. Comparison between the 2 groups was performed using the Student t test. RESULTS: Each arm had 12 subjects; 4 patients dropped out in the EVR arm and 1 in the CNI arm by 24 months. Serum creatinine (P = 0.015), Modification of Diet in Renal Disease estimated glomerular filtration rate (P = 0.013), and 24-hour urine CrCL (P = 0.032) were significantly better at 24 months with EVR. Iothalamate clearance showed significant improvement at 12 months (P = 0.049) and a trend toward better renal function (P = 0.099) at 24 months. There was no statistical significance with Cockcroft-Gault CrCl. Adverse events were not significantly different between the 2 arms. The EVR group also showed significantly better physical, functional, and overall self-reported quality of life (P = 0.01) at 24 months. CONCLUSIONS: EVR with MPA resulted in significant long-term improvement in renal function and quality of life at 24 months after liver transplantation compared with standard CNI with MPA immunosuppression.
RESUMO
OBJECTIVE: Little is known about the relationship between case volume and patient outcomes of those treated for ruptured abdominal aortic aneurysm (rAAA) after either endovascular aneurysm repair (EVAR) or open aneurysm repair (OAR). This study evaluated the impact of hospital case volume on outcomes after rAAA. METHODS: Patients with rAAA were identified in the Society for Vascular Surgery Vascular Quality Initiative database from 2003 to 2017, excluding patients from years in which a limited number of hospitals were included (2003-2009, 2017). Patients were stratified according to type of aneurysm repair and further stratified according to aortic surgical volume of the treating facility. Univariate and multivariable analyses were performed. RESULTS: Between 2010 and 2016, of 2895 patients who presented emergently with rAAA, 1246 underwent ruptured OAR (rOAR) and 1649 underwent ruptured EVAR (rEVAR). Before adjustment for demographics, comorbidities, and clinical characteristics, there were no differences in 1-year patient survival based on hospital OAR or EVAR volumes among patients undergoing rOAR or rEVAR. After adjustment for confounding variables, patients treated with rOAR at the highest volume OAR hospitals had a 33% lower hazard of mortality at 1 year relative to patients treated with rOAR at the lowest volume OAR hospitals. Preoperative interfacility transfer was associated with a 27% lower hazard of mortality after rOAR. There was no significant difference in hazard of mortality among patients undergoing rEVAR when they were stratified according to hospital EVAR volumes after adjustment for all other covariates. CONCLUSIONS: Outcomes after rAAA repair are associated with hospital volume among patients undergoing rOAR but not among patients undergoing rEVAR. Thus, centralization of care may have an important impact on outcomes when OAR is indicated, suggesting a benefit for preoperative interfacility transfer of care when it is feasible.

BACKGROUND: In an era of rapidly evolving surgical training, intraoperative teaching remains paramount to the education of surgical trainees. The impact of surgical trainees' level of expertise on outcomes after infrainguinal bypass surgery, a technically demanding operation, remains unknown. The purpose of this study was to explore the effects of surgical residents' experience on outcomes after infrainguinal bypass surgery. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database, we identified patients who underwent infrainguinal bypass from 2005 to 2012. Patients were stratified according to the training level of the most senior operating trainee. Univariate and multivariate analyses, as well as propensity score matched analysis, were performed to compare patient cohorts on operative time, length of hospital stay (LOS), bleeding, early graft failure, unplanned readmission, and 30-day mortality. RESULTS: A total of 19,579 patients were identified, of which 35.6% were female and 64.4% were male; mean age was 67.6 years. A PGY1 (postgraduate year) was the highest level trainee operating on 2.5%, a PGY2-4 for 26.2%, and a PGY5+ (postgraduate year 5 or greater) for 37.1%. Attending surgeons operated without trainees on 34.2%. PGY5+s were more likely to operate on patients who were younger, non-White, male, and on dialysis. In multivariable analysis, involvement of any surgical trainee was associated with procedures that took a greater length of time, had a greater odds of blood transfusion, and necessitated a longer hospital LOS relative to procedures performed by an attending surgeon alone. Only bypasses wherein PGY5+s were involved were associated with greater odds of early graft failure, unplanned readmission, and 30-day mortality when compared with procedures done without trainee involvement. After excluding lower extremity bypasses in which an attending surgeon operated without a trainee, propensity score matching analysis showed that patients operated on by PGY5+s had longer operative time (4.11 vs. 3.96 hr, P < 0.0001) and greater rates of postoperative bleeding (9.77% vs. 8.15%, P = 0.004) relative to patients operated on by attendings assisted by PGY1-4s, but no statistically significant difference in LOS, early graft failure, unplanned readmission, and perioperative mortality. CONCLUSIONS: Operative involvement of senior trainees was associated with worse outcomes during infrainguinal bypass, potentially reflecting a lesser extent of attending surgeon involvement, but no difference in patient outcomes after bypass procedure.

OBJECTIVE: The objective of our study was to determine the impact of embedding a pretest probability rule that is required during the computerized physician order-entry (CPOE) process on the appropriateness of CT angiography (CTA) of the pulmonary arteries for the diagnosis of pulmonary embolism (PE) in the emergency department (ED). MATERIALS AND METHODS: Data were obtained from the electronic medical records of all adults who visited the ED from October 17, 2010, through October 17, 2012 (n = 96,507). The primary outcome was the appropriateness of pulmonary CTA. Logistic regression was used to test whether rates of appropriate use, overuse, and underuse of pulmonary CTA improved significantly after the implementation of the decision support tool when controlling for other patient characteristics. RESULTS: Pulmonary CTA was appropriately used in 67.2% of patients with a modified Wells score of ≥ 4, a positive d-dimer test result, or both. CTA was overused in 19.3% of patients and underused in 13.5% of patients. Each additional month after the start of the intervention was associated with a 4-percentage point increase in the odds that the modified Wells score would indicate CTA had been used appropriately (odds ratio [OR] = 1.04; 95% CI, 1.01-1.07) and significantly lowered the odds of overuse of CTA (OR = 0.93; 95% CI, 0.90-0.96) based on the modified Wells score. These changes were not associated with any significant alteration in the level of CTA utilization or the positivity rate. CONCLUSION: The addition of a mandatory field in the CPOE record was associated with a significant improvement in the appropriate ordering of pulmonary CTA but did not change the PE positive rate or CTA utilization. It seems likely that physicians gradually inflated the modified Wells scores in spite of the fact that a threshold modified Wells score was not required to perform pulmonary CTA.

OBJECTIVE: To evaluate the cost-effectiveness of routine intraoperative ultrasonography (IOUS), cholangiography (IOC), or expectant management without imaging (EM) for investigation of clinically silent common bile duct (CBD) stones during laparoscopic cholecystectomy. BACKGROUND: The optimal algorithm for the evaluation of clinically silent CBD stones during routine cholecystectomy is unclear. METHODS: A decision tree model of CBD exploration was developed to determine the optimal diagnostic approach based on preoperative probability of choledocholithiasis. The model was parameterized with meta-analyses of previously published studies. The primary outcome was incremental cost per quality-adjusted life year (QALY) gained from each diagnostic strategy. A secondary outcome was the percentage of missed stones. Costs were from the perspective of the third party payer and sensitivity analyses were performed on all model parameters. RESULTS: In the base case analysis with a prevalence of stones of 9%, IOUS was the optimal strategy, yielding more QALYs (0.9858 vs 0.9825) at a lower expected cost ($311 vs $574) than EM. IOC yielded more QALYs than EM in the base case (0.9854) but at a much higher cost ($1122). IOUS remained dominant as long as the preoperative probability of stones was above 3%; EM was the optimal strategy if the probability was less than 3%. The percentage of missed stones was 1.5% for IOUS, 1.8% for IOC and 9% for EM. CONCLUSIONS: In the detection and resultant management of CBD stones for the majority of patients undergoing laparoscopic cholecystectomy, IOUS is cost-effective relative to IOC and EM.

BACKGROUND: Standard of care for patients with advanced gastric cancer includes administration of neoadjuvant chemotherapy (NAC) before resection. This study assesses the pattern of use and impact of NAC on perioperative outcomes in US medical centers. METHODS: Using the American College of Surgeons National Cancer Database, 16,128 patients underwent gastrectomy for cancer from 2003 to 2012. Treatment groups were categorized as NAC or no NAC (ie, adjuvant chemotherapy and surgery only). Univariate and multivariate analyses were performed to estimate trends in utilization and impact of treatment on perioperative outcomes. RESULTS: Of patients undergoing gastrectomy, 36.6% received NAC and 63.4% did not receive chemotherapy in the neoadjuvant setting. Patients who received NAC were more frequently younger, male, white, privately insured, with fewer comorbidities, and treated at an academic center (all P < .0001). After controlling for demographics, comorbidities, and tumor-related factors, patients who received NAC had a postoperative duration of stay 0.43 days shorter than patients who did not receive chemotherapy (5.79 vs 6.22 days; P = .050). They had a 36% lower odds of 30-day mortality (odds ratio, 0.64, P < .0001) but nonsignificant lower odds of 90-day mortality. Use of NAC increased annually, with the greatest increases seen in academic facilities and in the Northeast and North Central United States. CONCLUSION: With concerns regarding the toxicity of NAC, these findings suggest that NAC is not associated with worse postoperative outcomes. In light of evidence touting the benefits of NAC, its adoption as a component in the multimodality care of gastric cancer is slowly increasing, although use of NAC remains poor overall.

Sepsis mortality may be improved by early recognition and appropriate treatment based on evidence-based guidelines. An intervention was developed that focused on earlier identification of sepsis, early antimicrobial administration, and an educational program that was disseminated throughout all hospital units and services. There were 1331 patients with sepsis during the intervention period and 1401 patients with sepsis during the control period. After controlling for expected mortality, patients in the intervention period had 30% lower odds of dying (odds ratio = 0.70, 95% confidence interval [CI] = 0.57 to 0.84). They also had 1.07 fewer days on average in the intensive care unit (95% CI = -1.98 to -0.16), 2.15 fewer hospital days (95% CI = -3.45 to -0.86), and incurred on average $1949 less in hospital costs, although the effect on costs was not statistically significant. Continued incremental improvement and sustainment is anticipated through organizational oversight, continued education, and initiation of an automated electronic sepsis alert function.

OBJECTIVE: The aim of this study is to evaluate portal hypertension as an independent risk factor in general surgical procedures. BACKGROUND: Data on the impact of portal hypertension in general surgical outcomes has been limited. Published literature has focused mainly on its effect in liver surgery. The Child Pugh score and Model for End Stage Liver Disease are utilized for surgical risk assessment in liver disease but they do not accurately reflect degree of portal hypertension. METHODS: From 2005 to 2012, patients with esophageal varices (EV) in the National Surgical Quality Improvement Program (NSQIP) formed the portal hypertension cohort, and were case matched to patients without esophageal varices (NEV) based on sex, age, surgery type, and year of operation. Thirty day mortality and morbidity were analyzed using generalized estimating equations for binary outcomes. EV patients were also dichotomized by Model for End Stage Liver Disease (MELD) score (≤15 vs >15) and compared with NEV patients. RESULTS: One thousand five hundred and seventy-four EV patients were matched to 3148 NEV patients. In multivariable analysis, EV patients had a 3.01 higher odds of 30 day mortality (P < 0.001) and 1.28 higher odds of complications (P < 0.001) compared with NEV patients. EV patients with MELD >15 had 4.64 higher odds of death within 30 days (P < 0.001) and had 1.75 higher odds of complications within 30 days (P < 0.001) compared with NEV patients; EV patients with MELD 15 or less had 1.95 higher odds of 30 day mortality (P < 0.001) compared with NEV patients. CONCLUSIONS: Portal hypertension is associated with a significant mortality and morbidity risk in general surgery, and should not be underestimated even in patients with MELD 15 or less where the early mortality risk remained significant.

The normal physiologic stress mechanism, mediated by the sympathetic nervous system, causes a release of the neurotransmitters epinephrine and norepinephrine. Preclinical data have demonstrated an effect on tumor progression and metastasis via the sympathetic nervous system mediated primarily through the ß-adrenergic receptor (ß-AR) pathway. In vitro data have shown an increase in tumor growth, migration, tumor angiogenesis, and metastatic spread in breast cancer through activation of the ß-AR. Retrospective cohort studies on the clinical outcomes of ß-blockers in breast cancer outcomes showed no clear consensus. The purpose of this study was to perform a systematic review and meta-analysis of the effect of ß-blockers on breast cancer outcomes. A systematic review was performed using the Cochrane library and PubMed. Publications between the dates of January 2010 and December 2013 were identified. Available hazard ratios (HRs) were extracted for breast cancer recurrence, breast cancer death, and all-cause mortality and pooled using a random effects meta-analysis. A total of 7 studies contained results for at least 1 of the outcomes of breast cancer recurrence, breast cancer death, or all-cause mortality in breast cancer patients receiving ß-blockers. In the 5 studies that contained results for breast cancer recurrence, there was no statistically significant risk reduction (HR, 0.67; 95% confidence interval [CI], 0.39-1.13). Breast cancer death results were contained in 4 studies, which also suggested a significant reduction in risk (HR, 0.50; 95% CI, 0.32-0.80). Among the 4 studies that reported all-cause mortality, there was no significant effect of ß-blockers on risk (HR, 1.02; 95% CI, 0.75-1.37). Results of this systematic review and meta-analysis suggest that the use of ß-blockers significantly reduced risk of breast cancer death among women with breast cancer.

BACKGROUND: In the United States, ischemic stroke is a major cause of morbidity and mortality, precipitated by carotid artery stenosis in 1 of every 5 individuals who suffer a stroke. Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are 2 proven means of intervening on this disease process, with similar patient outcomes. Little is known about the burden of readmission after each of these procedures. We hypothesized that no difference in readmission rates within 30 days would exist for these 2 procedures, in spite of baseline differences that might exist between the 2 patient populations. METHODS: Using the Pennsylvania Health Care Cost Containment Council database, we identified 4,319 people who underwent CEA (n = 3,640) or CAS (n = 679) in Pennsylvania in 2011. Univariate analyses were performed to compare patient characteristics and outcomes, including reasons for readmission, between patients who underwent CEA and those who underwent CAS. Logistic regression was used to estimate the effect of intervention on 30-day readmission, after controlling for potential confounders. Time to readmission was analyzed using the Kaplan-Meier method. RESULTS: Patients who underwent CEA and CAS differed in a few notable ways, including age, race, admission type, and comorbid conditions such as congestive heart failure, hemiplegia and paraplegia, and renal disease. The unadjusted rate of 30-day readmission was 9.37% for CEA and 10.75% for CAS (P = 0.26). After controlling for patient and procedure characteristics, differences between 30-day readmission rates were still not statistically significant (odds ratio = 1.13; P = 0.39). Finally, time to readmission was similar for those who underwent CEA and those who underwent CAS (P = 0.19). Complications associated with surgery comprised less than 10% of primary readmission diagnoses for both groups. CONCLUSIONS: Readmission rates after CEA and CAS for carotid artery stenosis are approximately 10%. In spite of differences between patients with carotid stenosis who are selected for endarterectomy and stenting, the choice of procedure does not appear to be associated with different readmission rates or time to readmission, even after controlling for patient characteristics.

BACKGROUND: The benefit of Ladd's procedure for malrotation at a Children's Hospital (CH) has not previously been established. Our aim was to characterize the potential variations in management and outcomes between CH and Non-Children's Hospitals (NCH) in the treatment of malrotation with Ladd's procedure. METHODS: There were 2827 children identified with malrotation and complete information from the Kids' Inpatient Database (2003, 2006, 2009). Outcomes were compared between CH and NCH and evaluated with logistic and linear regressions. Additional propensity score matching was used to balance covariates between CH and NCH. RESULTS: There were 2261 (80.0%) children with malrotation undergoing Ladd's procedures treated at CH; 566 (20.0%) were treated at NCH. In multivariate analysis, CH was associated with a 39% lower odds of resection (p=0.004), with no differences observed for mortality, morbidity and LOS. Comparison of a propensity score matched cohort confirmed these findings, as well as demonstrated no significant differences in associated costs. CONCLUSIONS: The majority of pediatric intestinal malrotation is managed at CH. While measured outcomes of mortality, morbidity, LOS, and costs were not different at NCH, CH was less likely to perform intestinal resection during Ladd's procedure.

BACKGROUND: Readmission after colectomy has become an important metric for measuring quality of care. Our aim was to investigate the impact of patient and hospital characteristics on 30-d readmission rates among patients undergoing colectomies in Pennsylvania. METHODS: Data were obtained from the Pennsylvania Health Care Cost Containment Council, which included all patients undergoing colectomy during 2011 (n = 10,155). Characteristics of non-readmitted and readmitted patients were compared with univariate tests. The primary outcome was 30-d readmission, which was modeled using multivariable logistic regression. RESULTS: Of the 10,155 patients who underwent colectomy, 1492 (14.7%) were readmitted within 30 d of discharge. Readmission was influenced by the underlying diagnosis (P < 0.001). Additionally, readmission was more likely with a Charlson comorbidity index ≥ 2 (odds ratio [OR] = 1.57, P < 0.001), emergent admission (OR = 1.26, P = 0.001), an in-hospital complication (OR = 1.46, P < 0.001), lowest quartile for surgeon volume (OR = 1.24, P = 0.01), and construction of an ileostomy (OR = 2.31, P < 0.001). Factors associated with decreased likelihood of readmission included laparoscopic surgery (OR = 0.73, P < 0.001). No association with hospital volume was found. CONCLUSIONS: A 30-d readmission after colectomy is influenced by numerous patient- and surgeon-related factors. Reducing in-hospital complications, and improving patient education after ileostomy construction, provide substantial targets for intervention. Our data also suggest that there may be a critical range of colectomies performed annually by surgeons, greater than which no additional benefit is conferred in reducing readmissions, but below which there is an increased risk of readmission. Further research is needed to determine the influence of laparoscopic surgery in reducing readmission in equally matched patient populations.

Although previous studies have suggested that higher volumes of colectomies performed by surgeons and hospitals are associated with lower mortality, less is known about the relationship between volume and resource utilization. The research team tested the association between volume, costs, complications, length of stay, and mortality using data from the National Inpatient Sample. Results suggest higher volumes for both surgeons and hospitals were associated with lower costs, fewer complications, shorter length of stay, and lower mortality. Propensity score matching showed no significant difference in mortality by surgeon volume (7.38% vs 7.46%, P=.0.842), but significantly fewer complications (45.06% vs 49.10%, P=.008), shorter length of stay (11.8 vs 13.1 days, P<.0001), and lower costs ($33,142 vs $29,578, P<.0001) for high-volume surgeons. Although the major driver of complications and mortality is burden of disease and comorbid conditions, individual surgeon volume is an important determinant of length of stay and costs.

OBJECTIVES: To determine the rates of venous thromboembolism (VTE) during admission and within 30 days of hospital discharge in inflammatory bowel (IBD) patients undergoing colonic resection using the ACS National Surgical Quality Improvement Project (NSQIP) database and to compare these rates to VTE rates in cohorts of patients undergoing colonic resection for several other colonic pathologies. BACKGROUND: High rates of VTE have been demonstrated in hospitalized IBD patients. However, rates of postdischarge VTE in IBD patients are understudied. METHODS: Demographic, operative, and outcomes data for 96,999 patients undergoing colonic resection for diverticulitis, colorectal cancer (CRC), benign neoplasms, ulcerative colitis (UC), and Crohn's disease (CD) between 2005 and 2011 was obtained. Student t and χ tests were used for univariate analysis. A logistic multivariate analysis was performed with all significant variables. Propensity score matching was utilized to compare the VTE incidences between the groups. RESULTS: Highest VTE risk was seen in obese patients [odds ratio (OR) = 1.41], those older than 73 years (OR = 1.58) and with bleeding disorders (OR = 1.44), American Society of Anesthesiology class III/IV (OR = 1.52/1.86), preoperative systemic inflammatory response syndrome (OR = 1.55), sepsis (OR = 1.48) or steroid use (OR = 1.63), and primary diagnosis of UC (OR = 2.10). The UC group had the highest incidence of VTE (2.74%), followed by CRC patients (1.74%). A 1.2% incidence was seen in the CD population, and 41.5% of the UC-VTEs were diagnosed after discharge. CONCLUSIONS: This study affirms that inpatient UC patients undergoing colonic resection are at high risk for VTE and suggests that this risk persists into the postdischarge period. Thus, these patients should be given appropriate prophylaxis.

BACKGROUND: Although several studies have estimated the attributable cost and length of stay (LOS) of central line-associated bloodstream infections (CLABSIs) in the pediatric intensive care unit setting, little is known about the attributable costs and LOS of CLABSIs in the vulnerable pediatric hematology/oncology population. METHODS: We studied a total of 1562 inpatient admissions for 291 pediatric hematology/oncology patients at a single tertiary care children's hospital in the mid-Atlantic region between January 2008 and May 2011. Costs were normalized to year 2011 dollars. Propensity score matching was used to estimate the effect of CLABSIs on total cost and LOS while controlling for other covariates. RESULTS: Sixty CLABSIs occurred during the 1562 admissions. Compared with the patients without a CLABSI, those who developed a CLABSI tended to be older (9.0 years vs 7.5 years; P = .026) and to have a tunneled catheter (46.7% vs 27.0%) and a peripherally inserted central catheter (20.0% vs 11.2%) as opposed to other types of catheters (P < .0001). Propensity score matching yielded matched groups without significant differences in patient characteristics. In the propensity score analysis, the attributable LOS of a CLABSI was 21.2 days (P < .0001), and the attributable cost of a CLABSI was $69,332 (P < .0001). CONCLUSIONS: Among pediatric hematology/oncology patients, CLABSI was associated with an additional LOS of 21 days and increased costs of nearly $70,000. These findings may inform decisions regarding the value of investing in efforts to prevent CLABSIs in this vulnerable population.
