Risk factors of sudden unexpected death in patients with advanced cancer near the end of life

Background The definition of sudden unexpected death (SUD) in patients with advanced cancer near the end of life (EOL) was unclear. Methods This study was conducted as a single-center retrospective analysis. We analyzed 1,282 patients who died of advanced cancer from August 2011 to August 2019 retrospectively. We divided into patients who died within 24 h after the acute change of general condition or others and analyzed risk factors by a multiple logistics method. The reason for SUD was found, the reason is detected by using an electronic medical record retrospectively. The risk factors in SUD were analyzed using age, sex, EOL symptom and treatment, the primary site of cancer, metastatic site of cancer, comorbidly, chemotherapy, and Eastern Cooperative Oncology Group Performance Status. The primary endpoint was to identify the frequency and risk factors of SUD in patients with advanced cancer near the EOL. Results As a background, the median age is 73 years old, 690 males, 592 females, 227 gastroesophageal cancers, 250 biliary pancreatic cancers, 54 hepatocellular carcinomas, 189 colorectal cancer, 251 lung cancers, 71 breast cancers, 58 urological malignancies, 60 gynecological malignancies, 47 head and neck cancer, 31 hematological malignancies, and 22 sarcomas. The number of patients who died suddenly was 93 (7.2%) at EOL. In a multivariate analysis, Age (ORs 0.619), sex (ORs 1.700), patients with EOL delirium (ORs 0.483), nausea and vomiting (ORs 2.263), 1L or more infusion (ORs 3.479), EOL opioids (ORs 0.465), EOL sedations (ORs 0.339), and with cardiac comorbidity (ORs 0.345) were independent risk factors. Conclusions The frequency of patients who died suddenly was 7.2% (n = 93) at EOL. Age, sex, EOL symptom, EOL treatment, and cardiac comorbidity were independent risk factors in patients with advanced cancer near the EOL. Information on these risk factors is useful to explaining their EOL in advance.

New possibilities of screening for mental disorders in cardiology practice

Aim of the study: validation of novel algorithm for screening of mental comorbidity in general medical practice. Based on retrospectively formed registry of patients, we assessed an effectiveness of the previously proposed Psycho-cardiac comorbidity Index. An external validation was provided, with subgroup analysis on cohort of patients who presented with suspected “Non-ST-elevation acute coronary syndrome” (N = 577), with assessment of psychopharmacotherapy prescription rate and prevalence of anxiety and depression. Another validation was carried out via comparison with patients with verified mental disorders (N = 235). A positive association was found between magnitude of Psycho-cardiac comorbidity index and Hospital anxiety and depression subscales (r = 0.26, p < 0.001 for anxiety subscale, r = 0.17, p = 0.026 for depression subscale), over-diagnosis of acute coronary syndrome at pre-hospital stage (r = –0.27, p < 0.0001), as well as with neurotic, affective and somatoform mental disorders (average Index 8.59 vs. 7.52 points, U = 6040.5, p = 0.041). The found pattern may be useful for clinicians for screening for patients who require a multidisciplinary approach to diagnosis and treatment.

1668. Clinical Risk Score Model for Predicting Extended Spectrum Beta Lactamase (ESBL)-Positive Urinary Tract Infection among Hospitalized Filipino Patients: a Retrospective Single-Center Study

Background Infections caused by Extended-Spectrum B-lactamases (ESBL) organisms are an emerging health concern worldwide. In the background of progressive rise of antibiotic resistant organisms, efforts should be started to minimize antibiotic resistance. The development of clinical risk score models to predict the possibility of infection with these drug resistant organisms will bridge the gap between treating too late and treating too early and too much. Methods This is a single-center cross-sectional study of ESBL positive urinary tract infection (UTI) among patients admitted at St Luke’s Medical Center - Global City from January 2018 to December 2018. A total of 93 patients positive for ESBL-positive UTI and 186 patients with ESBL-negative UTI were included in the study. Clinical characteristics, medical and medication histories were obtained from the computerized medical database. To develop the risk score, clinical risk indicators measured at the time of recruitment were built by logistic regression. Regression coefficients were transformed into item scores and added up to a total score. A risk-scoring scheme was developed from clinical predictors. Results The following factors were observed to be predictive of ESBL UTI: hospital-acquired or healthcare-associated infection, prior ESBL infection, cardiac comorbidity and history of carbapenem intake. Scoring for the predictive model is as follows: having age at least 50 years old=1.5, hospital-acquired or healthcare-associated infection=1, having prior ESBL infection=2, having cardiac comorbidity (NYHA I-II)=1, having cardiac comorbidity (NYHA III-IV)=2.5, and history of carbapenem intake=3. ROC analysis showed that the optimum cut point in the model predictive of ESBL is 3.5/10. The risk prediction model for ESBL had high sensitivity of 87%, medium specificity of 68%, and good predictive accuracy of 0.78. Conclusion A simple and non-invasive scoring scheme of three predictors provides good prediction indices for presence of ESBL organisms in patients diagnosed with UTI. However, a large sample study is needed to improve the power of the study. Validation studies are also needed. Disclosures All Authors: No reported disclosures

Are patients with stage III non-small cell lung cancer treated with chemoradiotherapy at risk for cardiac events? Results from a retrospective cohort study

ObjectivesDyspnoea is one of the symptoms frequently encountered after treatment with chemoradiotherapy (CRT) in stage III non-small cell lung cancer (NSCLC). Long-term data on mild to moderately severe cardiac events as underlying cause of dyspnoea in patients with stage III NSCLC are lacking. Therefore, the incidence of new cardiac events, with a common terminology criteria for adverse events (CTCAE) score of ≥2 within 5 years after diagnosis, were analysed.DesignRetrospective multicentre cohort study of patients with stage III NSCLC treated with CRT from 2006 to 2013. The medical files of the treated patients were reviewed.Outcome measuresThe primary endpoint of the study was the incidence of new cardiac events with a CTCAE score of ≥2 within 5 years after diagnosis. Secondary endpoint was to identify risk factors associated with the development of a cardiac event.ResultsFour hundred and sixty patients were included in the study. Of all patients, 150 (32.6%) developed a new cardiac event. In patients with a known cardiac history (n=138), 44.2% developed an event. The most common cardiac events were arrhythmia (14.6%), heart failure (7.6%) and symptomatic coronary artery disease (6.8%). Pre-existent cardiac comorbidity (HR 1.96; p<0.01) and WHO-performance score ≥2 (HR 2.71; p<0.01) were significantly associated with developing a cardiac event. The majority of patients did not have pre-existent cardiac comorbidity (n=322). Elevated WHO/International Society of Hypertension score was not identified as a significant predictor for cardiac events.ConclusionOne-third of patients with stage III NSCLC treated in daily clinical practice develop a new cardiac event within 5 years after CRT. All physicians confronted with patients with NSCLC should take cardiac comorbidity as a serious possible explanation for dyspnoea after treatment with CRT.
