Value Added Impact of Both Point-of-Care and Laboratory Lactic Acid Analysis When Emergently Evaluating Cancer Patients.

INTRODUCTION: Cancer patients are immunosuppressed and may present to an emergency department with atypical symptoms. In the emergency setting, it is important ascertain rapidly if lactic acid levels are high, either due to sepsis or tumor lysis syndrome, to effectively manage symptoms. Therefore, it is critical to determine the blood lactic acid level to timely identify who is at risk of sepsis and provide early intervention. We have compared blood lactic acid concentrations (BLAC) in cancer patients obtained by point-of-care testing (POCT) and those measured by laboratory analysis in blood samples drawn within a short time of each other. METHODS: This was a retrospective study in cancer patients whose BLAC had been determined by POCT and laboratory analysis. Only those patients who had blood withdrawn for both testing methods within a 2-h timeframe were included in the study. Regressions were performed together with an analysis categorizing the BLAC from both testing methods. RESULTS: A total of 274 patients met the criteria for the study. The BLAC from POCT correlated well with the values from laboratory testing (R = 0.925). Categorization of BLAC showed that 88.32% of the patients had BLAC that directly matched between the two tests; 28 (10.22%) patients had a normal BLAC according to laboratory analysis but a high BLAC on POCT; and four (1.46%) patients had a high BLAC according laboratory analysis but normal BLAC on POCT. CONCLUSIONS: There was a high correlation between POCT and laboratory analysis values of BLAC in cancer patients, with the results from both testing methods agreeing 96% of the time. This finding suggests that POCT would suffice in most cases. Importantly, in 2% of the cancer patients who presented emergently, BLAC determined by POCT and laboratory analysis did not agree. Therefore, in subsequent decision-making, we recommend that if sepsis is suspected and BLAC determined by POCT is normal, nucleic acids, proteins, circulating cells, and interleukin-3 levels should also be obtained by POCT to confirm sepsis and/or rule out tumor lysis syndrome in patients with cancer.

Evaluation of Cancer Patients With Suspected Pulmonary Embolism: Performance of the American College of Physicians Guideline.

BACKGROUND: Accurate risk stratification of pulmonary embolism (PE) can reduce unnecessary imaging. We investigated the extent to which the American College of Physicians (ACP) guideline for evaluation of patients with suspected PE could be applied to cancer patients in the emergency department of a comprehensive cancer center. MATERIALS AND METHODS: Data from cancer patients who underwent CT pulmonary angiography (CTPA) between August 1, 2015, and October 31, 2015, were collected. We assessed each patient's diagnostic workup for its adherence to the ACP guideline in terms of clinical risk stratification and age-adjusted d-dimer level and the degree to which these factors were associated with PE. RESULTS: Of the 380 patients identified, 213 (56%) underwent CTPA indicated per the ACP guideline, and 78 (21%) underwent CTPA not indicated per the guideline. Only one of the patients who underwent nonindicated CTPA had a PE. Fifty-seven patients underwent unnecessary d-dimer evaluation, and 71 patients with negative d-dimer test results underwent nonindicated CTPA. PEs were found in 6 of 108 (6%) low-risk patients, 22 of 219 (10%) intermediate-risk patients, and 13 of 53 (25%) high-risk patients. The ACP guideline had negative predictive value of 99% (95% confidence interval: 93%-100%) and sensitivity of 97% (95% confidence interval: 86%-100%) in predicting PE. CONCLUSION: The ACP guideline has good sensitivity for detecting PE in cancer patients and thus can be applied in this population. Compliance with the ACP guideline when evaluating cancer patients with suspected PE could reduce the use of unnecessary imaging and laboratory studies.

Depression and survival outcomes after emergency department cancer pain visits.

OBJECTIVES: Pain and depression frequently co-occur in patients with cancer. Although pain is a common reason for emergency department (ED) presentation by these patients, depression frequently goes unrecognised during an ED visit. In this study, we assessed the risk for depression in patients with cancer presenting to the ED for uncontrolled pain and assessed the extent to which the risk for depression was associated with survival in this population. METHODS: Participants were consecutive patients with cancer taking Schedule II opioids (n=209) who presented to the ED of a tertiary cancer centre for uncontrolled pain. Risk for depression was assessed using the Center for Epidemiologic Studies Depression Scale (CES-D), excluding the somatic symptoms. Survival was calculated from date of ED visit to date of death/last follow-up. RESULTS: The CES-D was completed by 197 of 209 participants (94.3%); of these, 81 of 197 (41.1%) had high risk for depression (CES-D ≥10). The mean survival time for the entire sample was 318 days (SD=33), with 84 deaths. Cox proportional hazards regression modeling showed that risk for depression and disease stage (CES-D ≥10: HR=1.75, 95% CI 1.11 to 2.78, p=0.016; disease stage: HR=2.52, 95% CI 1.20 to 5.30, p<0.001) were significant factors for survival. CONCLUSIONS: Risk for depression was prevalent and associated with survival outcomes in patients with cancer presenting to the ED with uncontrolled pain. Screening for risk for depression in the ED may identify patients who need referral for clinical assessment of depression. Diagnosis and adequate treatment could improve health outcomes and survival rates for these patients.

Handoff Tool Enabling Standardized Transitions Between the Emergency Department and the Hospitalist Inpatient Service at a Major Cancer Center.

Communication failures during patient handoff can lead to serious errors. A quality improvement team created a standardized handoff tool/process (DE-PASS: Decisive problem requiring admission, Evaluation time, Patient summary, Acute issues/action list, Situation unfinished/awareness, Signed out to) for admitting patients from the emergency department (ED) to the hospitalist inpatient service of a tertiary cancer center. DE-PASS mirrors the institution's ED workflow, stratifies patients as stable/urgent/emergent, and establishes requirements for verbal and email communications between providers. Comparison of preintervention and postintervention results from the 1-month pilot revealed that within a 24-hour period, DE-PASS reduced the number of intensive care unit transfers by 58% ( P = .393), the number of rapid-response team calls by 39% ( P = .637), and time to inpatient order by 31% ( P = .004). ED physicians' and hospitalists' satisfaction with DE-PASS increased. Reduction in intensive care unit transfers was sustained after the pilot ( P = .029). DE-PASS feasibility was evidenced by 100% uptake. By stratifying patients by risk level, DE-PASS reduced admission-to-evaluation times for unstable patients, potentially improving patient safety.

Presenting Symptoms in the Emergency Department as Predictors of Intensive Care Unit Admissions and Hospital Mortality in a Comprehensive Cancer Center.

PURPOSE: The identification of patients at high risk for poor outcomes may allow for earlier palliative care and prevent futile interventions. We examined the association of presenting symptoms on risk of intensive care unit (ICU) admission and hospital death among patients with cancer admitted through an emergency department (ED). METHODS: We queried MD Anderson Cancer Center databases for all patients who visited the ED in 2010. Presenting symptoms, ICU admissions, and hospital deaths were reviewed; patient data analyzed; and risk factors for ICU admission and hospital mortality identified. RESULTS: The main presenting symptoms were pain, fever, and respiratory distress. Of the patients with cancer who visited the ED, 5,362 (58%) were admitted to the hospital at least once (range, 1 to 13 admissions), 697 (13%) were admitted to the ICU at least once, and 587 (11%) died during hospitalization (31% of 233 patients with hematologic malignancies and 27% of 354 patients with solid tumors died in the ICU; P < .001). In multivariable logistic regression, presenting symptoms of respiratory distress or altered mental status; lung cancer, leukemia, or lymphoma; and nonwhite race were independent predictors of hospital death. Patients who died had a longer median length of hospital stay than patients discharged alive (14 v 6 days for hematologic malignancies and 7 v 5 days for solid tumors; P < .001). CONCLUSION: Patients with cancer admitted through an ED experience high ICU admission and hospital mortality rates. Patients with advanced cancer and respiratory distress or altered mental status may benefit from palliative care that avoids unnecessary interventions.

Prevalence of Hypothyroidism and Its Association with Diabetes Mellitus in Patients of an Ambulatory Clinic.

Hypothyroidism is the most common thyroid disorder in the adult population. Studies have found a higher prevalence of overt hypothyroidism in type 2 diabetic population than in the general population, but the relationship between subclinical hypothyroidism and diabetes mellitus 2 is still controversial. The aim of this study is to estimate the prevalence rate of hypothyroidism in the adult population receiving services in an ambulatory clinic and to determine if there is an association between hypothyroidism and diabetes mellitus. From the database of all adult patients who attended the outpatient clinic at Family Medicine Center Policlínica Bella Vista in Mayagüez, P.R. during 2014, a random sample of 200 subjects was obtained and the medical records were reviewed. The prevalence rate of diabetes mellitus in this group was 22% and the prevalence rate of hypothyroidism was 17%. The prevalence rate of hypothyroidism in diabetic patients was 10/44 (22.7%). The prevalence rate of hypothyroidism in non-diabetic patients was 24/156 (15.4%). The prevalence ratio was 1.48 (95% CI: 0.77, 2.85; X2 = 1.31, p = 0.25). The results of this cross-sectional study showed a non-statistically significant tendency for a higher prevalence of hypothyroidism in diabetic patients, which suggest that screening for hypothyroidism among patients with diabetes should be considered. More studies with more patients are necessary to investigate the association between thyroid dysfunction and diabetic patients.

Effect of blockade of the EGF system on wound healing in patients vaccinated with CIMAvax® EGF.

BACKGROUND: The epidermal growth factor receptor (EGFR) signaling system is frequently unbalanced in human malignancies due to increased ligand production, receptor overexpression, receptor mutations, and/or cross-talk with other receptor systems. For this reason, the EGFR is an attractive target for anticancer therapy. The epidermal growth factor also plays an important role in regulating multiple facets of cutaneous wound healing, including inflammation, wound contraction, proliferation, migration, and angiogenesis. In the Center of Molecular Immunology, a cancer vaccine is produced (CIMAvax® EGF) that blocks the binding of EGF to its receptor. This blockade causes a significant inverse association between the anti-EGF antibody titers and EGF concentration. Around 1,500 patients with non-small cell lung cancer have been treated, showing that this vaccine is safe, immunogenic, increases survival and improves quality of life. Taking into account the therapeutic benefits of CIMAvax® EGF vaccination and the role of EGF-EGFR system in the wound healing process, we decided to conduct a retrospective research with the aim of determining the effect to the CIMAvax® EGF vaccine on the wound healing process in patients undergoing surgical treatment. METHODS: Medical records of 452 vaccinated patients were reviewed and only six patients receiving surgical treatment were identified. Further information about these six patients was obtained from source documents, including medical records and operative reports using an observational list that included different variables. Post-surgical wound healing complications were identified using the National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI-CTC) version 3.0. RESULTS: None of the six patients operated on presented adverse events related to the wound healing, that is to say, no wound dehiscence, wound infection, delayed wound healing, fistula formation, abscess formation or hemorrhage/bleeding associated with surgery during treatment with CIMAvax® EGF occurred. CONCLUSIONS: These results suggest that the use of CIMAvax® EGF does not produce a deleterious effect in the wound healing process.

Conocimiento de los médicos y la población cubana sobre los ensayos clínicos / Knowledge of the Cuban doctors and population about the clinical assays

Se elaboraron y validaron 2 encuestas con el objetivo de determinar la percepción y el conocimiento de los médicos y el público sobre los ensayos clínicos. Los médicos fueron encuestados en instituciones hospitalarias hasta un total de 267 especialistas. Se encuestó una muestra de 405 personas tomadas al azar de la población en general. Algunos médicos y el público en general tienen dificultades para explicar que es un ensayo clínico. En Cuba se han incrementado los conocimientos sobre los ensayos clínicos, sin embargo, aún no existe una cultura general sobre este tipo de investigación. Deben aprovecharse todas las posibilidades de los medios de comunicación para la divulgación de temas relacionados con los ensayos clínicos
