On the preference for linear regression models in children: Results of a field study in elementary school children.

We aimed at showing that children are able to identify and draw a line of best fit through a cloud of points according to the concept of linear regression. A sample of 72 children in third and fourth primary school grades were given two different tasks. In a first task, 10 different sheets with three illustrations of the same scatterplot with different lines of regression to choose from were presented.

Markov Model of the Outpatient Classification System Morbidity Related Groups (MRG).

Background: Benchmarking and guidance of outpatient physicians in Germany are almost always based on one year data. This also holds true for morbidity related groups, a classification system applied in northern Germany since 2017. A study of the markov properties of prescription based grouping algorithms is reported here.

Analysis of Age and Gender Structures for ICD-10 Diagnoses in Outpatient Treatment Using Shannon's Entropy.

Introduction: Diagnostic diversity has been in the focus of several studies of health services research. As the fraction of people with statutory health insurance changes with age and gender it is assumed that diagnostic diversity may be influenced by these parameters.

Methods: We analyze fractions of patients in Schleswig-Holstein with respect to the chapters of the ICD-10 code in outpatient treatment for quarter 2/2016 with respect to age and gender/sex of the patient.

Routine Data Analyses to Compare Outpatient Depression Treatment Regimens.

Background: Routine data analyses are becoming increasingly important for health policy decision making. However such databases often vary in data quality, completeness and accessibility. The aim of this study is to describe the quality of a large outpatient healthcare database, the process of data extraction and to give a brief overview of data-structure with focusing on provider-type and disease severity in an example of the treatment of depressive disorders.

Morbidity Related Groups (MRG) for Epidemiological Analysis in Outpatient Treatment.

Each patient in outpatient treatment is assigned per quarter and corresponding physician to a case group that is strongly related to the morbidity (Morbidity Related Group, MRG). MRG is defined by the drug group on a four character level in the international anatomic-therapeutic-chemical (ATC) classification with the largest costs as an indicator for the severity of the drug treatment. Using severity levels we get a risk adjustment with respect to age and polypharmacy as an indicator for multimorbidity and treatment intensity.

Admission of out-of-hospital cardiac arrest victims to a high volume cardiac arrest center is linked to improved outcome.

Aim: Cardiac arrest centers have been associated with improved outcome for patients after cardiac arrest. Aim of this study was to investigate the effect on outcome depending on admission to high-, medium- or low volume centers.

Methods: Analysis from a prospective, multicenter registry for out of hospital cardiac arrest patients treated by the emergency medical service of Vienna, Austria.

Life-threatening pacemaker dysfunction associated with therapeutic radiation: a case report.

Reports about pacemaker (PM) dysfunction during irradiation (IR) are very rare, which is because of the extensive protective mechanisms that exist in these devices against electromagnetic interference (EMI). We report a case in which one of the most clinically relevant type of PM malfunctions, a runaway PM, occurred during radiation in a 76-year-old woman who was treated for inoperable esophageal cancer with a course of photon IR. The estimated IR dose of 0.
