Karla Köpke, Kerstin Prahm, Silke Buda, Walter Haas
BACKGROUND: Every year epidemic waves of influenza and other acute respiratory infections (ARIs) cause a highly variable burden of disease in the population. Thus, assessment of the situation and adaptation of prevention strategies have to rely on real time syndromic surveillance. OBJECTIVE: We have established an ICD-10-based electronic system allowing rapid capture and transmission of information on ARI (SEED(ARI)), in Germany. Here we report the evaluation of this new system based on results of the syndromic and virologic surveillance carried out by the working group on influenza in Germany (AGI)...

BACKGROUND: Frailty is a measure of physiologic reserve associated with increased vulnerability to adverse outcomes following surgery in older adults. The 'accumulating deficits' model of frailty has been applied to the NSQIP database, and an 11-item modified frailty index (mFI) has been validated. We developed a condensed 5-item frailty index and used this to assess the relationship between frailty and outcomes in patients undergoing paraesophageal hernia (PEH) repair. METHODS: The NSQIP database was queried for ICD-9 and CPT codes associated with PEH repair...

OBJECTIVES: Rapid response teams (RRT) respond to signs of deterioration in order to avoid morbidity and mortality. Early RRT activation (eRRT) in patients admitted from the emergency department (ED) is associated with significantly increased mortality. Predicting these events may represent an opportunity to identify patients who would benefit from further resuscitation, aid disposition decision making, or improve communication between ED and inpatient providers. We aimed to create a clinical prediction instrument to quantify the risk of eRRT...

OBJECTIVE: This article describes how maps were developed from the clinical modifications of the 9th and 10th revisions of the International Classification of Diseases (ICD) to the Abbreviated Injury Scale 2005 Update 2008 (AIS08). The development of the mapping methodology is described, with discussion of the major assumptions used in the process to map ICD codes to AIS severities. There were many intricacies to developing the maps, because the 2 coding systems, ICD and AIS, were developed for different purposes and contain unique classification structures to meet these purposes...
