Differential response to neoadjuvant endocrine therapy for Black/African American and White women in NCDB.

PURPOSE: Compared to White women, there are higher mortality rates in Black/African American (BAA) women with hormone receptor-positive breast cancer (HR + BC) which may be partially due to differences in treatment resistance. We assessed factors associated with response to neoadjuvant endocrine therapy (NET). METHODS: The National Cancer Database (NCDB) was queried for women with clinical stage I-III HR + BC diagnosed 2006-2017 and treated with NET. Univariate and multivariate analyses described associations between the sample, duration of NET, and subsequent treatment response, defined by changes between clinical and pathological staging. RESULTS: The analytic sample included 9864 White and 1090 BAA women. Compared to White women, BAA women were younger, had more co-morbidities, were higher stage at presentation, and more likely to have > 24 weeks of NET. After excluding those with unknown pT/N/M, 3521 White and 365 BAA women were evaluated for NET response. On multivariate analyses, controlling for age, stage, histology, HR positivity, and duration of NET, BAA women were more likely to downstage to pT0/Tis (OR 3.0, CI 1.2-7.1) and upstage to Stage IV (OR 2.4, CI 1.002-5.6). None of the women downstaged to pT0/Tis presented with clinical stage III disease; only 2 of the women upstaged to Stage IV disease presented with clinical Stage I disease. CONCLUSION: Independent of NET duration and clinical stage at presentation, BAA women were more likely to experience both complete tumor response and progression to metastatic disease. These results suggest significant heterogeneity in tumor biology and warrant a more nuanced therapeutic approach to HR + BC.

An implementation science approach to the systematic study of access to gynecologic cancer care.

INTRODUCTION: Barriers to access to cancer care are profoundly threatening to patients with gynecologic malignancies. Implementation science focuses on empirical investigation of factors influencing delivery of clinical best practices, as well as interventions designed to improve delivery of evidence-based care. We outline one prominent framework for conducting implementation research and discuss its application to improving access to gynecologic cancer care. METHODS: Literature on the use of the Consolidated Framework for Implementation Research (CFIR) was reviewed. Delivery of cytoreductive surgery for advanced ovarian carcinoma was selected as an illustrative case of an evidence-based intervention (EBI) in gynecologic oncology. CFIR domains were applied to the context of cytoreductive surgical care, highlighting examples of empirically-assessable determinants of care delivery. RESULTS: CFIR domains include Innovation, Inner Setting, Outer Setting, Individuals, and Implementation Process. "Innovation" relates to characteristics of the surgical intervention itself; "Inner Setting" relates to the environment in which surgery is delivered. "Outer Setting" refers to the broader care environment influencing the Inner Setting. "Individuals" highlights attributes of persons directly involved in care delivery, and "Implementation Process" focuses on integration of the Innovation within the Inner Setting. CONCLUSIONS: Prioritization of implementation science methods in the study of access to gynecologic cancer care will help ensure that patients are able to utilize interventions with the greatest prospect of benefiting them.

The Impact of Surgical Boot Camp on Medical Student Confidence and Imposter Syndrome.

INTRODUCTION: Transitioning from medical student to surgical intern is accompanied by increased responsibility, stress, and clinical burden. This environment lends itself to imposter syndrome (IS), a psychological condition grounded in self-doubt causing fear of being discovered as fraud despite adequate abilities. We hypothesized a 2-week surgical boot camp for fourth year medical students would improve confidence in technical skills/knowledge and IS. METHODS: Thirty medical students matching into surgical specialties completed the boot-camp in February 2020. Presurveys/postsurveys assessed confidence levels using a 1-5 Likert scale regarding 32 technical skills and knowledge points. The Clance Impostor Phenomenon Scale (CIPS) assessed IS, where increasing scores correlate to greater IS. RESULTS: Median (interquartile range [IQR]) subject age was 27 y (26, 28), 20 (66.7%) were male, and 21 (70%) were Caucasian. Of the 30 students, 23 (76.7%) had a break in training with a median [IQR] of 2 [1, 3] y outside of medicine. Confidence scores were significantly improved in all five assessment categories (P < 0.05); however, there was no change in CIPS in median [IQR] presurveys versus postsurveys (65.5 [52, 75] versus 64 [52, 75], P = 0.70). Females had higher mean (standard deviation) pre-CIPS than males (68.4 [15.2] versus 61.6 [14.9], P = 0.02). There was no strong correlation between age and CIPS in the presurvey (Spearman Rank Correlation Coefficient [SRCC]: 0.29, P = 0.19) or postsurvey (SRCC: 0.31, P = 0.10). While subjects who worked outside of medicine had a stronger relationship with IS (SRCC: 0.37, P = 0.05), multivariable regression analysis did not reveal any significant differences. CONCLUSIONS: We advocate for surgical boot-camp training courses to improve trainee skill and confidence. As IS is not improved by boot camp, additional research is needed to identify opportunities to improve IS among surgical trainees.

The Impact of Commission on Cancer Accreditation Status, Hospital Rurality and Hospital Size on Quality Measure Performance Rates.

BACKGROUND: Rural cancer patients receive lower-quality care and experience worse outcomes than urban patients. Commission on Cancer (CoC) accreditation requires hospitals to monitor performance on evidence-based quality measuresPlease confirm the list of authors is correc, but the impact of accreditation is not clear due to lack of data from non-accredited facilities and confounding between patient rurality and hospital accreditation, rurality, and size. METHODS: This retrospective, observational study assessed associations between rurality, accreditation, size, and performance rates for four CoC quality measures (breast radiation, breast chemotherapy, colon chemotherapy, colon nodal yield). Iowa Cancer Registry data were queried to identify all eligible patients diagnosed between 2011 and 2017. Cases were assigned to the surgery hospital to calculate performance rates. Univariate and multivariate regression models were fitted to identify patient- and hospital-level predictors and assess trends. RESULTS: The study cohort included 10,381 patients; 46% were rural. Compared with urban patients, rural patients more often received treatment at small, rural, and non-accredited facilities (p < 0.001 for all). Rural hospitals had fewer beds and were far less likely to be CoC-accredited than urban hospitals (p < 0.001 for all). On multivariate analysis, CoC accreditation was the strongest, independent predictor of higher hospital performance for all quality measures evaluated (p < 0.05 in each model). Performance rates significantly improved over time only for the colon nodal yield quality measure, and only in urban hospitals. CONCLUSIONS: CoC accreditation requires monitoring and evaluating performance on quality measures, which likely contributes to better performance on these measures. Efforts to support rural hospital accreditation may improve existing disparities in rural cancer treatment and outcomes.

Hospital and Surgeon Selection for Medicare Beneficiaries With Stage II/III Rectal Cancer: The Role of Rurality, Distance to Care, and Colonoscopy Provider.

OBJECTIVE: To determine factors associated with rectal cancer surgery performed at high-volume hospitals (HVHs) and by high-volume surgeons (HVSs), including the roles of rurality and diagnostic colonoscopy provider characteristics. SUMMARY OF BACKGROUND DATA: Although higher-volume hospitals/surgeons often achieve superior surgical outcomes, many rectal cancer resections are performed by lower-volume hospitals/surgeons, especially among rural populations. METHODS: Patients age 66+ diagnosed from 2007 to 2011 with stage II/III primary rectal adenocarcinoma were selected from surveillance, epidemiology, and end results-medicare data. Patient ZIP codes were used to classify rural status. Hierarchical logistic regression was used to determine factors associated with surgery by HVH and HVS. RESULTS: Of 1601 patients, 22% were rural and 78% were urban. Fewer rural patients received surgery at a HVH compared to urban patients (44% vs 65%; P < 0.0001). Compared to urban patients, rural patients more often had colonoscopies performed by general surgeons (and less often from gastroenterologists or colorectal surgeons), and lived substantially further from HVHs; these factors were both associated with lower odds of surgery at a HVH or by a HVS. In addition, whereas over half of both rural and urban patients received their colonoscopy and surgery at the same hospital, rural patients who stayed at the same hospital were significantly less likely to receive surgery at a HVH or by a HVS compared to urban patients. CONCLUSIONS: Rural rectal cancer patients are less likely to receive surgery from a HVH/HVS. The role of the colonoscopy provider has important implications for referral patterns and initiatives seeking to increase centralization.

Prevention of Firearm Violence Through Specific Types of Community-based Programming: An Eastern Association for the Surgery of Trauma Evidence-based Review.

OBJECTIVE: The purpose of this review was to provide an evidence-based recommendation for community-based programs to mitigate gun violence, from the Eastern Association for the Surgery of Trauma (EAST). SUMMARY BACKGROUND DATA: Firearm Injury leads to >40,000 annual deaths and >115,000 injuries annually in the United States. Communities have adopted culturally relevant strategies to mitigate gun related injury and death. Two such strategies are gun buyback programs and community-based violence prevention programs. METHODS: The Injury Control and Violence Prevention Committee of EAST developed Population, Intervention, Comparator, Outcomes (PICO) questions and performed a comprehensive literature and gray web literature search. Using GRADE methodology, they reviewed and graded the literature and provided consensus recommendations informed by the literature. RESULTS: A total of 19 studies were included for analysis of gun buyback programs. Twenty-six studies were reviewed for analysis for community-based violence prevention programs. Gray literature was added to the discussion of PICO questions from selected websites. A conditional recommendation is made for the implementation of community-based gun buyback programs and a conditional recommendation for community-based violence prevention programs, with special emphasis on cultural appropriateness and community input. CONCLUSIONS: Gun violence may be mitigated by community-based efforts, such as gun buybacks or violence prevention programs. These programs come with caveats, notably community cultural relevance and proper support and funding from local leadership.Level of Evidence: Review, Decision, level III.

Surgical Decision-Making Surrounding Contralateral Prophylactic Mastectomy: Comparison of Treatment Goals, Preferences, and Psychosocial Outcomes from a Multicenter Survey of Breast Cancer Patients.

BACKGROUND: Differences in patient characteristics and decision-making preferences have been described between those who elect breast-conserving surgery (BCS), unilateral mastectomy (UM), or contralateral prophylactic mastectomy (CPM) for breast cancer. However, it is not known whether preferred and actual decision-making roles differ across these surgery types, or whether surgery choice reflects a woman's goals or achieves desired outcomes. METHODS: Women diagnosed with stage 0-III unilateral breast cancer across eight large medical centers responded to a mailed questionnaire regarding treatment decision-making goals, roles, and outcomes. These data were linked to electronic medical records. Differences were assessed using descriptive analyses and logistic regression. RESULTS: There were 750 study participants: 60.1% BCS, 17.9% UM, and 22.0% CPM. On multivariate analysis, reducing worry about recurrence was a more important goal for surgery in the CPM group than the others. Although women's preferred role in the treatment decision did not differ by surgery, the CPM group was more likely to report taking a more-active-than-preferred role than the BCS group. On multivariate analysis that included receipt of additional surgery, posttreatment worry about both ipsilateral and contralateral recurrence was higher in the BCS group than the CPM group (both p < 0.001). The UM group was more worried than the CPM group about contralateral recurrence only (p < 0.001). CONCLUSIONS: Women with CPM were more likely to report being able to reduce worry about recurrence as a very important goal for surgery. They were also the least worried about ipsilateral breast recurrence and contralateral breast cancer almost two years postdiagnosis.

Improving the Quality of Cancer Care in Community Hospitals.

BACKGROUND: Cancer patients treated in community hospitals receive less guideline-recommended care and experience poorer outcomes than those treated in academic medical centers or National Cancer Institute-Designated Cancer Centers. The Markey Cancer Center Affiliate Network (MCCAN) was designed to address this issue in Kentucky, the state with the highest cancer incidence and mortality rates in the U.S. METHODS: Using data obtained from the Kentucky Cancer Registry, the study evaluated the impact of patients treated in MCCAN hospitals on four evidence-based Commission on Cancer (CoC) quality measures using a before-and-after matched-cohort study design. Each group included 13 hospitals matched for bed size, cancer patient volume, community population, and region (Appalachian vs. non-Appalachian). Compliance with quality measures was assessed for the 3 years before the hospital joined MCCAN (T1) and the 3 years afterward (T2). RESULTS: In T1, the control hospitals demonstrated greater compliance with two quality measures than the MCCAN hospitals. In T2, the MCCAN hospitals achieved greater compliance in three measures than the control hospitals. From T1 to T2, the MCCAN hospitals significantly increased compliance on three measures (vs. 1 measure for the control hospitals). Although most of the hospitals were not accredited by the CoC in T1, 92% of the MCCAN hospitals had achieved accreditation by the end of T2 compared with 23% of the control hospitals. CONCLUSION: After the MCCAN hospitals joined the Network, their compliance with quality measures and achievement of CoC accreditation increased significantly compared with the control hospitals. The unique academic/community-collaboration model provided by MCCAN was able to make a significant impact on improvement of cancer care. Future research is needed to adapt and evaluate similar interventions in other states and regions.

Fever in the ICU: A Predictor of Mortality in Mechanically Ventilated COVID-19 Patients.

PURPOSE: While fever may be a presenting symptom of COVID-19, fever at hospital admission has not been identified as a predictor of mortality. However, hyperthermia during critical illness among ventilated COVID-19 patients in the ICU has not yet been studied. We sought to determine mortality predictors among ventilated COVID-19 ICU patients and we hypothesized that fever in the ICU is predictive of mortality. MATERIALS AND METHODS: We conducted a retrospective cohort study of 103 ventilated COVID-19 patients admitted to the ICU between March 14 and May 27, 2020. Final follow-up was June 5, 2020. Patients discharged from the ICU or who died were included. Patients still admitted to the ICU at final follow-up were excluded. RESULTS: 103 patients were included, 40 survived and 63(61.1%) died. Deceased patients were older {66 years[IQR18] vs 62.5[IQR10], (p = 0.0237)}, more often male {48(68%) vs 22(55%), (p = 0.0247)}, had lower initial oxygen saturation {86.0%[IQR18] vs 91.5%[IQR11.5], (p = 0.0060)}, and had lower pH nadir than survivors {7.10[IQR0.2] vs 7.30[IQR0.2] (p < 0.0001)}. Patients had higher peak temperatures during ICU stay as compared to hospital presentation {103.3°F[IQR1.7] vs 100.0°F[IQR3.5], (p < 0.0001)}. Deceased patients had higher peak ICU temperatures than survivors {103.6°F[IQR2.0] vs 102.9°F[IQR1.4], (p = 0.0008)}. Increasing peak temperatures were linearly associated with mortality. Febrile patients who underwent targeted temperature management to achieve normothermia did not have different outcomes than those not actively cooled. Multivariable analysis revealed 60% and 75% higher risk of mortality with peak temperature greater than 103°F and 104°F respectively; it also confirmed hyperthermia, age, male sex, and acidosis to be predictors of mortality. CONCLUSIONS: This is one of the first studies to identify ICU hyperthermia as predictive of mortality in ventilated COVID-19 patients. Additional predictors included male sex, age, and acidosis. With COVID-19 cases increasing, identification of ICU mortality predictors is crucial to improve risk stratification, resource management, and patient outcomes.

The association of socioeconomic status with receipt of neoadjuvant chemotherapy.

BACKGROUND: There are advantages to neoadjuvant chemotherapy in operable breast cancer, particularly for those with higher-risk cancers, but little is known about factors that are associated with the use of neoadjuvant chemotherapy outside of clinical trials. We examined whether use of neoadjuvant chemotherapy instead of adjuvant chemotherapy varies by nonclinical factors such as patient socioeconomic status or rural residence. METHODS: Women diagnosed with breast cancer in 2013-2014 at eight medical institutions were surveyed by mail regarding their experiences with breast cancer treatment, and this information was linked to hospital-based cancer registries. We examined the use of neoadjuvant chemotherapy among women with histologically confirmed invasive stage I-III breast cancer and used regression models to examine the association of socioeconomic status with chemotherapy timing. We also explored potential mechanisms for those differences. RESULTS: Over 29% of the chemotherapy sample overall received neoadjuvant chemotherapy. Neoadjuvant receipt was lower for those with income < $100,000 (AOR 0.56, 95% CI 0.2-0.9) even with adjustment for other demographics, stage, and biomarker status, and findings for education and a variable for both lowest education and income < $100,000 were similar. Rural/urban residence was not associated with neoadjuvant receipt. Differences by income in perceptions of the importance of neoadjuvant chemotherapy advantages and disadvantages did not appear to explain the differences in use by income. CONCLUSIONS: In a multicenter sample of breast cancer patients, lower income was strongly associated with less receipt of neoadjuvant chemotherapy. Since patients with lower socioeconomic status are more likely to present with later-stage disease, this pattern has the potential to contribute to breast cancer outcome disparities.

Early and Locally Advanced Metaplastic Breast Cancer: Presentation and Survival by Receptor Status in Surveillance, Epidemiology, and End Results (SEER) 2010-2014.

BACKGROUND: Metaplastic breast cancer (MBC) is a rare disease subtype characterized by an aggressive clinical course. MBC is commonly triple negative (TN), although hormone receptor (HR) positive and human epidermal growth receptor 2 (HER2) positive cases do occur. Previous studies have reported similar outcomes for MBC with regard to HR status. Less is known about outcomes for HER2 positive MBC. MATERIALS AND METHODS: Surveillance, Epidemiology, and End Results Program data were used to identify women diagnosed 2010-2014 with MBC or invasive ductal carcinoma (IDC). Kaplan-Meier curves estimated overall survival (OS) and multivariate Cox models were fitted. For survival analyses, only first cancers were included, and 2014 diagnoses were excluded to allow for sufficient follow-up. RESULTS: Our MBC sample included 1,516 women. Relative to women with IDC, women with MBC were more likely to be older (63 vs. 61 years), black (16.0% vs. 11.1%), and present with stage III disease (15.6% vs. 10.8%). HER2 positive and HER2 negative/HR positive MBC tumors represented 5.2% and 23.0% of cases. For MBC overall, 3-year OS was greatest for women with HER2 positive MBC (91.8%), relative to women with TN (75.4%) and HER2 negative/HR positive MBC (77.1%). This difference was more pronounced for stage III MBC, for which 3-year OS was 92.9%, 47.1%, and 42.2% for women with HER2 positive, TN, and HER2 negative/HR positive MBC, respectively. A multivariate Cox model of MBC demonstrated that HER2 positive tumors (relative to TN) were associated with improved survival (hazard ratio = 0.32, 95% confidence interval [CI] 0.13-0.79). In a second Cox model of exclusively HER2 positive tumors, OS did not differ between MBC and IDC disease subtypes (hazard ratio = 1.16, 95% CI 0.48-2.81). CONCLUSION: In this contemporary, population-based study of women with MBC, HER2 but not HR status was associated with improved survival. Survival was similar between HER2 positive MBC and HER2 positive IDC. This suggests HER2 positive MBC is responsive to HER2-directed therapy, a finding that may offer insights for additional therapeutic approaches to MBC. IMPLICATIONS FOR PRACTICE: This population-based study reports recent outcomes, by receptor status, for women with metaplastic breast cancer. Survival in metaplastic breast cancer is not impacted by hormone receptor status. To the authors' knowledge, this is the first report indicating that women with human epidermal growth receptor 2 (HER2) positive metaplastic breast cancer have survival superior to women with HER2 negative metaplastic breast cancer and survival similar to women with HER2 positive invasive ductal carcinoma. This information can be used for counseling patients diagnosed with metaplastic breast cancer. Further understanding of HER2 positive metaplastic breast cancer could offer insights for the development of therapeutic approaches to metaplastic breast cancer more broadly.

Nipple-Sparing Mastectomy is Not Associated with a Delay of Adjuvant Treatment.

BACKGROUND: High-volume single-institution studies support the oncologic safety of nipple sparing mastectomy (NSM). Concerns remain regarding the increased potential for complications, recurrence, and delays to subsequent adjuvant therapy. A national database was used to examine treatment and outcomes for NSM patients. METHODS: Women undergoing unilateral NSM or skin sparing mastectomy (SSM) for stage 0-4 breast cancer from 2004 to 2013 were identified from the National Cancer Database. Demographic and oncologic characteristics, short-term outcomes and time to local and systemic treatment were compared. RESULTS: NSM was performed on 8173 patients: 8.7% were node positive, and for stage 1-4 disease, 10.6% were triple negative (TN) and 15.3% were HER2-positive. NSM patients were less likely than SSM patients to receive chemotherapy [CT] (37.4 vs. 43.4%) or radiation [PMRT] (15.6 vs. 16.9%), and were also more likely to present with clinically early-stage disease. NSM patients with high-risk features were more likely to receive CT in the neoadjuvant [NCT] than adjuvant setting [AC] (OR 3.76, 1.81, and 1.99 for clinical N2/3, TN, and HER2-positive disease, all p < 0.001). On multivariate analysis, NSM patients had a higher rate of pathologic complete response [pCR] (OR 1.41, p < 0.001). Readmission rate, positive margin rate and time to CT, PMRT or hormonal therapy were not increased for NSM compared to SSM patients. CONCLUSIONS: Over one third of NSM patients received chemotherapy and/or radiation. NSM patients with high-risk features were more likely to receive NAC and obtain a pCR. NSM patients did not experience worse outcomes or delayed adjuvant therapy compared to SSM.

Impact of vitamin D on pathological complete response and survival following neoadjuvant chemotherapy for breast cancer: a retrospective study.

BACKGROUND: There has been interest in the potential benefit of vitamin D (VD) to improve breast cancer outcomes. Pre-clinical studies suggest VD enhances chemotherapy-induced cell death. Vitamin D deficiency was associated with not attaining a pathologic complete response (pCR) following neoadjuvant chemotherapy (NAC) for operable breast cancer. We report the impact of VD on pCR and survival in an expanded cohort. METHODS: Patients from Iowa and Montpellier registries who had serum VD level measured before or during NAC were included. Vitamin D deficiency was defined as < 20 ng/mL. Pathological complete response was defined as no residual invasive disease in the breast and lymph nodes. Survival was defined from the date of diagnosis to the date of relapse (PFS) or date of death (OS). RESULTS: The study included 327 women. Vitamin D deficiency was associated with the odds of not attaining pCR (p = 0.04). Fifty-four patients relapsed and 52 patients died. In multivariate analysis, stage III disease, triple-negative (TN) subtype and the inability to achieve pCR were independently associated with inferior survival. Vitamin D deficiency was not significantly associated with survival in the overall sample; however a trend was seen in the TN (5-years PFS 60.4% vs. 72.3%, p = 0.3), and in the hormone receptor positive /human epidermal growth factor receptor 2 negative (HER2-) subgroups (5-years PFS 89% vs 78%, p = 0.056). CONCLUSION: Vitamin D deficiency is associated with the inability to reach pCR in breast cancer patients undergoing NAC.

Male Breast Cancer as a Second Primary Cancer: Increased Risk Following Lymphoma.

BACKGROUND: Male breast cancer (MBC) as a second primary cancer (SPC) has a known association with prior MBC. However, its association with non-breast index malignancies, relative to population risk, has not been previously reported. MATERIALS AND METHODS: Using Surveillance, Epidemiology, and End Results program (9 catchment area) data, we identified MBCs diagnosed from 1973-2012 as their SPC. Information regarding the index malignancy was also obtained. Standardized incidence ratios (SIR) of MBC as SPC were estimated, along with incidence rates and trends. Kaplan-Meier curves were used to estimate survival. RESULTS: Over a 38-year period, 464 MBCs were identified as SPC. The most common index malignancies were breast (SIR 30.86, 95% confidence interval [CI] 21.50-42.92, p < .001), lymphoma (SIR 1.58, 95% CI 1.08-2.22, p = .014), melanoma (SIR 1.26, 95% CI 0.80-1.89), urinary (SIR 1.05, 95% CI 0.74-1.43), colorectal (SIR 0.94, 95% CI 0.69-1.24), and prostate (SIR 0.93 95% CI 0.81-1.07). Apart from the known association with prior breast cancer, the only significant association was with lymphoma as an index cancer, although not significant with a Bonferroni correction. From 1975-2012, incidence of breast cancer as a first cancer increased at an annual percentage change of 1.3% while breast cancer as a SPC increased at 4.7% (both p values < .001). CONCLUSION: Male breast cancer as a SPC has increased markedly over 4 decades. Men with a history of lymphoma may experience higher-than-expected rates of breast SPC. These observations warrant further research, and suggest possible etiologic connections with disease biology, prior therapy, or genetics. IMPLICATIONS FOR PRACTICE: This study reports that men are presenting more frequently to the clinic with breast cancer, both as an initial cancer and as a second cancer following an earlier malignancy. We also report the novel observation that men who survive lymphoma are at increased risk of developing a subsequent breast cancer. Further work is needed to better understand possible treatment or biologic causes of this association. More immediately, these findings suggest the need for heightened vigilance for male breast cancer overall and, in particular, for male lymphoma survivors.

Higher Fluid Balance Increases the Risk of Death From Sepsis: Results From a Large International Audit.

OBJECTIVES: Excessive fluid therapy in patients with sepsis may be associated with risks that outweigh any benefit. We investigated the possible influence of early fluid balance on outcome in a large international database of ICU patients with sepsis. DESIGN: Observational cohort study. SETTING: Seven hundred and thirty ICUs in 84 countries. PATIENTS: All adult patients admitted between May 8 and May 18, 2012, except admissions for routine postoperative surveillance. For this analysis, we included only the 1,808 patients with an admission diagnosis of sepsis. Patients were stratified according to quartiles of cumulative fluid balance 24 hours and 3 days after ICU admission. MEASUREMENTS AND MAIN RESULTS: ICU and hospital mortality rates were 27.6% and 37.3%, respectively. The cumulative fluid balance increased from 1,217 mL (-90 to 2,783 mL) in the first 24 hours after ICU admission to 1,794 mL (-951 to 5,108 mL) on day 3 and decreased thereafter. The cumulative fluid intake was similar in survivors and nonsurvivors, but fluid balance was less positive in survivors because of higher fluid output in these patients. Fluid balances became negative after the third ICU day in survivors but remained positive in nonsurvivors. After adjustment for possible confounders in multivariable analysis, the 24-hour cumulative fluid balance was not associated with an increased hazard of 28-day in-hospital death. However, there was a stepwise increase in the hazard of death with higher quartiles of 3-day cumulative fluid balance in the whole population and after stratification according to the presence of septic shock. CONCLUSIONS: In this large cohort of patients with sepsis, higher cumulative fluid balance at day 3 but not in the first 24 hours after ICU admission was independently associated with an increase in the hazard of death.

Trauma team size and task performance in adult trauma resuscitations.

BACKGROUND: The initial evaluation of a trauma patient involves multiple personnel from various disciplines. Whereas this approach can expedite care, an increasing number of personnel can also create chaos and hinder efficiency. We sought to determine the optimal number of persons associated with an expedient primary survey. METHODS: Audio and/or video recordings of all consecutive adult trauma evaluations at a level 1 trauma center were reviewed for a 1-month period. A 20-task checklist was developed based on Advanced Trauma Life Support principles. The number of practitioners present (TeamN) and tasks completed at 2 and 5 min (Task2, Task5) were recorded. The association between TeamN, demographics, presence of attending surgeon, and team leader engagement and Task2/Task5 was measured the using chi square test and Spearman correlation. A multivariate regression model was developed. RESULTS: A total of 170 cases were reviewed, 44 of which were top-tier activations. Average TeamN was 6 ± 2 persons. Task2 and Task5 were significantly positively correlated with TeamN (r = 0.34, P < 0.0001; r = 0.22, P = 0.004, respectively) and leader engagement (r = 0.27, P < 0.01; r = 0.16, P < 0.05, respectively). There was a significant positive correlation between TeamN and Task2 and Task5. Only TeamN had a significant, independent association with Task2 and Task5 (P = 0.005). We did not find a size that was negatively associated with task completion. Only assessment of breath sounds was negatively associated with increasing team size. CONCLUSIONS: TeamN is significantly associated with efficiency of trauma evaluation. Studies evaluating reasons for this and the effect of maximal team size are needed to determine optimal trauma team staffing.

Critical Care for the Patient With Multiple Trauma.

Trauma remains the leading cause of death worldwide and the leading cause of death in those less than 44 years old in the United States. Admission to a verified trauma center has been shown to decrease mortality following a major injury. This decrease in mortality has been a direct result of improvements in the initial evaluation and resuscitation from injury as well as continued advances in critical care. As such, it is vital that intensive care practitioners be familiar with various types of injuries and their associated treatment strategies as well as their potential complications in order to minimize the morbidity and mortality frequently seen in this patient population.

Variation in geographic access to chemotherapy by definitions of providers and service locations: a population-based observational study.

BACKGROUND: An aging population, with its associated rise in cancer incidence and strain on the oncology workforce, will continue to motivate patients, healthcare providers and policy makers to better understand the existing and growing challenges of access to chemotherapy. Administrative data, and SEER-Medicare data in particular, have been used to assess patterns of healthcare utilization because of its rich information regarding patients, their treatments, and their providers. To create measures of geographic access to chemotherapy, patients and oncologists must first be identified. Others have noted that identifying chemotherapy providers from Medicare claims is not always straightforward, as providers may report multiple or incorrect specialties and/or practice in multiple locations. Although previous studies have found that specialty codes alone fail to identify all oncologists, none have assessed whether various methods of identifying chemotherapy providers and their locations affect estimates of geographic access to care. METHODS: SEER-Medicare data was used to identify patients, physicians, and chemotherapy use in this population-based observational study. We compared two measures of geographic access to chemotherapy, local area density and distance to nearest provider, across two definitions of chemotherapy provider (identified by specialty codes or billing codes) and two definitions of chemotherapy service location (where chemotherapy services were proven to be or possibly available) using descriptive statistics. Access measures were mapped for three representative registries. RESULTS: In our sample, 57.2 % of physicians who submitted chemotherapy claims reported a specialty of hematology/oncology or medical oncology. These physicians were associated with 91.0 % of the chemotherapy claims. When providers were identified through billing codes instead of specialty codes, an additional 50.0 % of beneficiaries (from 23.8 % to 35.7 %) resided in the same ZIP code as a chemotherapy provider. Beneficiaries were also 1.3 times closer to a provider, in terms of driving time. Our access measures did not differ significantly across definitions of service location. CONCLUSIONS: Measures of geographic access to care were sensitive to definitions of chemotherapy providers; far more providers were identified through billing codes than specialty codes. They were not sensitive to definitions of service locations, as providers, regardless of how they are identified, generally provided chemotherapy at each of their practice locations.

Surgical Management of Breast Cancer in 2010-2011 SEER Registries by Hormone and HER2 Receptor Status.

BACKGROUND: Although locoregional recurrence is known to affect overall survival for operable breast cancer, the impact of receptor status on locoregional control is debated. Currently, hormone receptor (HR) and human epidermal growth factor receptor-2 (HER2) status are generally not considered relevant to surgical choice. This study examines recent population-level surgical trends with regard to receptor status. METHODS: We used the Surveillance, Epidemiology, and End Results (SEER) data to identify stage I-III female breast cancers diagnosed from 2010 to 2011. Patients were categorized by HR and HER2 receptor status. Univariate and multivariate logistic regressions were used to assess factors associated with undergoing mastectomy and the choice of contralateral prophylactic mastectomy (CPM). RESULTS: The overall mastectomy rate for the 87,504 women diagnosed in 2010-2011 was 43.4 %. On multivariate analysis, the odds of receiving mastectomy was greater for HER2-positive disease with either HR-negative or HR-positive status, than for women with HER2-negative/HR-positive disease (odds ratio 1.73 and 1. 31, respectively; all p values <0.001). Age, stage, marital status, race, and year of diagnosis also correlated with mastectomy. Triple-negative breast cancer (TNBC) was associated with CPM, while HER2 status was not. The mastectomy rate, which increased overall from 2006 to 2010, has continued to increase for stage III disease but has decreased for stage I disease. Mastectomy rates overall were lower in 2011 than 2010 (p = 0.012). CONCLUSIONS: HER2-positive disease and TNBC were independent predictors of more extensive surgery in this large, recent, population-based cohort. Although mastectomy rates have continued to increase for stage III disease, mastectomy rates overall were lower in 2011 than in previous years.
