Malnutrition is associated with six-month mortality in older patients admitted to the emergency department with hip fracture.

Background: Hip fractures in older people are a common health problem often associated with malnutrition that might affect outcomes. Screening for malnutrition is not a routine examination in emergency departments (ED). This analysis of the EMAAge study, a prospective, multicenter cohort study, aimed to evaluate the nutritional status of older patients (≥ 50 years) with hip fracture, factors associated with malnutrition risk, and the association between malnutrition and the six-months mortality. Methods: Risk of malnutrition was evaluated using the Short Nutritional Assessment Questionnaire. Clinical data as well as data on depression and physical activity were determined. Mortality was captured for the first six months after the event. To assess factors associated with malnutrition risk we used a binary logistic regression. A Cox proportional hazards model was used to assess the association of malnutrition risk with six-month survival adjusted for other relevant risk factors. Results: The sample consisted of N = 318 hip fracture patients aged 50 to 98 (68% women). The prevalence of malnutrition risk was 25.3% (n = 76) at the time of injury. There were no differences in triage categories or routine parameters measured in the ED that could point to malnutrition. 89% of the patients (n = 267) survived for six months. The mean survival time was longer in those without malnutrition risk (171.9 (167.1-176.9) days vs. 153.1 (140.0-166.2) days). The Kaplan Meier curves and the unadjusted Cox regression (Hazard Ratio (HR) 3.08 (1.61-5.91)) showed differences between patients with and patients without malnutrition risk. In the adjusted Cox regression model, risk of death was associated with malnutrition risk (HR 2.61, 1.34-5.06), older age (70-76 years: HR 2.5 (0.52-11.99); 77-82 years: HR 4.25 (1.15-15.62); 83-99 years: HR 3.82 (1.05-13.88)) and a high burden of comorbidities (Charlson Comorbidity Index ≥3: HR 5.4 (1.53-19.12)). Conclusion: Risk of malnutrition was associated with higher mortality after hip fracture. ED parameters did not differentiate between patients with nutritional deficiencies and those without. Therefore, it is particularly important to pay attention to malnutrition in EDs to detect patients at risk of adverse outcomes and to initiate early interventions.

Primary and secondary data in emergency medicine health services research - a comparative analysis in a regional research network on multimorbid patients.

BACKGROUND: This analysis addresses the characteristics of two emergency department (ED) patient populations defined by three model diseases (hip fractures, respiratory, and cardiac symptoms) making use of survey (primary) and routine (secondary) data from hospital information systems (HIS). Our aims were to identify potential systematic inconsistencies between both data samples and implications of their use for future ED-based health services research. METHODS: The research network EMANET prospectively collected primary data (n=1442) from 2017-2019 and routine data from 2016 (n=9329) of eight EDs in a major German city. Patient populations were characterized using socio-structural (age, gender) and health- and care-related variables (triage, transport to ED, case and discharge type, multi-morbidity). Statistical comparisons between descriptive results of primary and secondary data samples for each variable were conducted using binomial test, chi-square goodness-of-fit test, or one-sample t-test according to scale level. RESULTS: Differences in distributions of patient characteristics were found in nearly all variables in all three disease populations, especially with regard to transport to ED, discharge type and prevalence of multi-morbidity. Recruitment conditions (e.g., patient non-response), project-specific inclusion criteria (e.g., age and case type restrictions) as well as documentation routines and practices of data production (e.g., coding of diagnoses) affected the composition of primary patient samples. Time restrictions of recruitment procedures did not generate meaningful differences regarding the distribution of characteristics in primary and secondary data samples. CONCLUSIONS: Primary and secondary data types maintain their advantages and shortcomings in the context of emergency medicine health services research. However, differences in the distribution of selected variables are rather small. The identification and classification of these effects for data interpretation as well as the establishment of monitoring systems in the data collection process are pivotal.

Self-reported health and life satisfaction in older emergency department patients: sociodemographic, disease-related and care-specific associated factors.

BACKGROUND: Self-reported health (SRH) and life satisfaction (LS) are patient-reported outcomes (PROs) that independently predict mortality and morbidity in older adults. Emergency department (ED) visits due to serious health problems or accidents might pose critical life events for patients. This study aimed (a) to characterize older patients' SRH and LS during the distinct event of an ED stay, and (b) to analyze concomitant associations of PROs with ED patients' sociodemographic, disease-specific and care-related variables. METHODS: Study personnel recruited mostly older ED patients from three disease groups during a two-year period (2017-2019) in eight EDs in central Berlin, Germany, in the context of the health services research network EMANet. Cross-sectional data from the baseline patient survey and associated secondary data from hospital information systems were analyzed. Multilevel linear regression models with random intercept were applied to assess concomitant associations with SRH (scale: 0 (worst) to 100 (best)) and LS (scale: 0 (not at all satisfied) to 10 (completely satisfied)) as outcomes, including sensitivity analyses. RESULTS: The final sample comprised N = 1435 participants. Mean age was 65.18 (SD: 16.72) and 50.9% were male. Mean ratings of SRH were 50.10 (SD: 23.62) while mean LS scores amounted to 7.15 (SD: 2.50). Better SRH and higher LS were found in patients with cardiac symptoms (SRH: ß = 4.35, p = .036; LS: ß = 0.53, p = .006). Worse SRH and lower LS were associated with being in need of nursing care (SRH: ß = - 7.52, p < .001; LS: ß = - 0.59, p = .003) and being unemployed (SRH: ß = - 8.54, p = .002; LS: ß = - 1.27, p < .001). Sex, age, number of close social contacts, and hospital stays in the previous 6 months were additionally related to the outcomes. Sensitivity analyses largely supported results of the main sample. CONCLUSIONS: SRH and LS were associated with different sociodemographic and disease-related variables in older ED patients. Nursing care dependency and unemployment emerged as significant factors relating to both outcomes. Being able to identify especially vulnerable patients in the ED setting might facilitate patient-centered care and prevent negative health outcomes. However, further longitudinal research needs to analyze trajectories in both outcomes and suitable intervention possibilities in the ED setting.

Point-of-care testing for influenza in a university emergency department: A prospective study.

BACKGROUND: Seasonal influenza is a burden for emergency departments (ED). The aim of this study was to investigate whether point-of-care (POC) PCR testing can be used to reduce staff sick days and improve diagnostic and therapeutic procedures. OBJECTIVES: The aim of this study was to investigate whether point-of-care (POC) PCR testing can be used to reduce staff sick days and improve diagnostic and therapeutic procedures. METHODS: Using a cross-over design, the cobas® Liat® Influenza A/B POC PCR test (Liat) was compared with standard clinical practice during the 2019/2020 influenza season. All adult patients (aged ≥ 18 years) with fever (≥38°C) and respiratory symptoms were included. Primary end points were the prevalence of influenza infections in the ED and staff sick days. Secondary end points were frequency of antiviral and antibacterial therapy, time between admission and test result or treatment initiation, patient disposition, ED length of stay (LOS), and for inpatients mortality and LOS. Nurses were interviewed about handling and integration of POC testing. The occurrence of SARS-CoV-2 infections coincided with the second half of the study. RESULTS: A total of 828 patients were enrolled in the study. All 375 patients of the intervention group were tested with Liat, and 103 patients of them (27.6%) tested positive. During the intervention period, staff sick days were reduced by 34.4% (P = .023). Significantly, more patients in the intervention group received antiviral therapy with neuraminidase inhibitors (7.2% vs 3.8%, P = .028) and tested patients received antibiotics more frequently (40.0% vs 31.6%, P = .033). Patients with POC test were transferred to external hospitals significantly more often (5.6% vs 1.3%, P = .01). CONCLUSION: We conclude that POC testing for influenza is useful in the ED, especially if it is heavily frequented by patients with respiratory symptoms.

High-sensitivity cardiac troponin T for diagnosis of NSTEMI in the elderly emergency department patient: a clinical cohort study.

PURPOSE: The aim of this study is to evaluate the impact of age on the diagnostic performance of high-sensitivity troponin T (hsTnT) under routine conditions. MATERIALS AND METHODS: Data of 4118 consecutive emergency department (ED) patients who underwent a routine TnT measurement between 11 October 2012 and 30 November 2013 were analysed. Diagnostic accuracy of hsTnT was compared in four age categories (<50, 50-64, 65-74, ≥75 years of age) for different cut-off values. Primary endpoint was a main hospital diagnosis of NSTEMI. RESULTS: The median age of the study population (n = 4118) was 61 years (IQR: 45-75 years). NSTEMI was diagnosed in 3.3% (n = 136) of all patients. There were significant differences in hsTnT concentrations between age-groups (p < 0.001) in all patients, but not in NSTEMI patients (p = 0.297). 72.2% of all patients ≥75 years of age (583/808) without NSTEMI had hsTnT concentrations above the 99th percentile of a healthy reference population. Specificity at 14 ng/L was 93.6% (95% CI: 92.12-94.87) in patients below 50 years of age and 27.9% (95% CI: 24.78-31.08) in patients 75 years of age and older. CONCLUSIONS: Patients' age needs to be considered at least one influencing factor on hsTnT concentrations at admission and should be included in the clinical interpretation of hsTnT concentrations for further clinical workup beneath other influencing factors like comorbidities and symptom onset time. The implementation of age-specific cut-off values could be considered for single troponin testing at admission but is associated with an increased risk of underdiagnosis of NSTEMI.

Scald burns in children aged 14 and younger in Australia and New Zealand­an analysis based on the Burn Registry of Australia and New Zealand (BRANZ).

INTRODUCTION: Scalds are a common injury in children and a frequent reason for hospitalisation despite being a preventable injury. METHODS: This retrospective two year study reports data from 730 children aged 14 years or younger who sustained a scald between 2009 and 2010 and were admitted to a burns centre in Australia or New Zealand. Data were extracted from the Burn Registry of Australia and New Zealand (BRANZ), which included data from 13 burns centres in Australia and New Zealand. RESULTS: Scald injury contributed 56% (95% CI 53-59%) of all pediatric burns. There were two high risk groups; male toddlers age one to two, contributing 34% (95% CI 31-38%) of all scalds, and indigenous children who were over 3 times more likely to experience a scald requiring admission to a burns unit than their non-indigenous peers. First aid cooling by non-professionals was initiated in 89% (95% CI 86-91%) of cases but only 20% (95% CI 16-23%) performed it as recommended. CONCLUSION: This study highlights that effective burn first aid reduces hospital stay and reinforces the need to encourage, carers and bystanders to deliver effective first aid and the importance of targeted prevention campaigns that reduce the burden of pediatric scald burns in Australia and New Zealand.

Hedgehog pathway as a potential treatment target in human cholangiocarcinoma.

BACKGROUND: Innovative treatment concepts targeting essential signaling pathways may offer new chances for patients suffering from cholangiocarcinoma (CCC). For that, we performed a systematic molecular genetic analysis concerning the Hedgehog activity in human CCC samples and analyzed the effect of Hh inhibition on CCC cells in vitro and in vivo. METHODS: Activation of the Hh pathway was analyzed in 50 human CCC samples using quantitative polymerase chain reaction (qPCR). The efficacy of Hh inhibition using cyclopamine and BMS-833923 was evaluated in vitro. In addition, the effect of BMS-833923, alone or in combination with gemcitabine, was analyzed in vivo in a murine subcutaneous xenograft model. RESULTS: Expression analysis revealed a significant activation of the Hh-signaling pathway in nearly 50% of CCCs. Hh inhibition resulted in a significant decrease in cell proliferation of CCC cells. Moreover, a distinct inhibition of tumor growth could be seen as a result of a combined therapy with BMS-833923 and gemcitabine in CCC xenografts. CONCLUSION: The results of our study suggest that the Hh pathway plays a relevant role at least in a subset of human CCC. Inhibition of this pathway may represent a possible treatment option for CCC patients in which the Hh pathway is activated.
