Centralization of emergency hospital care is not associated with increased in-hospital mortality; a population-based cohort study.

BACKGROUND: We describe changes in the distance travelled, the utilization of emergency services, and the inhospital mortality before and after the centralization of hospital emergency services in Denmark. METHODS: All unplanned non-psychiatric hospital contacts from adults (aged ≥18 years) in 2008 and 2016 are included. Analyses are age-standardized and conducted at a municipality level. The municipalities are divided into groups according to the presence of emergency hospital services. RESULTS: Municipalities where hospitals with emergency services have been closed differed by having the most significant increase in distance travelled from 2008 to 2016. All groups experienced a reduction in overall in-hospital mortality. The reduction in mortality was not present for acute myocardial infarct contacts from municipalities where hospitals with emergency services have been closed. CONCLUSION: Our data do not suggest that hospital closures, and thereby increased travel distance, have contributed significantly as a barrier to emergency-care access and changes to in-hospital mortality.

Can High-Sensitivity Troponins Predict Future Hypertension? A Systematic Literature Review.

Hypertension (HT) is associated with cardiovascular events and increased mortality, and identification of persons at risk in due time is therefore important. Finding a biomarker to identify those at risk will enable early preventive treatment, and high-sensitivity cardiac troponin (hs-cTn) seems to be a highly relevant candidate. To gather the existing knowledge on the association between hs-cTn and future HT, a systematic literature review was conducted following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) reporting guidelines and using the PICOS system. Medline was searched until August 2018. Of 45 extracted papers, eleven papers were eligible for the study. None were randomized controlled trials. Three studies assessed hs-cTnI, eight studies assessed hs-cTnT. All studies found statistically significant associations between hs-cTn concentrations and future HT, but the studies included different types of blood pressure (diastolic, systolic, diurnal). Due to differences in troponin assay construction and test capability, a direct comparison of test performance in terms of specificity, sensitivity and predictive values was not possible, and a specific hs-cTn cutoff value for HT prediction could therefore not be defined. Furthermore, a number of conditions known to affect troponin concentrations (e.g. gender, renal function, and co-morbidities) were not sufficiently studied. All retrieved studies found significant associations between hs-cTn concentrations and future HT; although the findings are promising, the studies were too heterogeneous, and many conditions affecting troponin concentrations needs investigation at these low concentrations before hs-cTn can be considered a useful HT predictor.
