Arashinris Model-Based Development of Embedded Systems Quality assurance processes included data element range and consistency checks in the web-based data entry forms, dual data entry, chart re-review for a randomly selected sample of records, and annual site visits by members of the ROC Data Coordinating Center to review randomly selected study records, data capture processes, and local data quality efforts. We evaluated 18 clinical, operational, procedural, and outcome variables obtained using each data processing strategy. These analyses were carried out by the investigators; neither the Clinical Trials Center nor the Publications Committee of the Resuscitation Outcomes Consortium takes responsibility for the analyses and interpretation of results. Operational variables included four time intervals response, on-scene, transport, and total out-of-hospital time.

The research staff involved in manual data processing included: This is the first study we are aware of that directly compares a maximized all-electronic approach to more traditional case identification and data abstraction routines for outcomes-based out-of-hospital research. There were notable differences in case ascertainment and acuity between patients identified with the two approaches. The smaller sample size generated through manual processing is primarily explained by a more restrictive approach for case identification.

Greenland S, Finkle WD. We want to acknowledge and thank the many contributing EMS agencies, EMS providers, and study staff for their willingness to participate in and support this project, for their continued dedication to improving the quality and efficiency of out-of-hospital data collection, and for supporting data-driven approaches to improving the care and outcomes for patients served by EMS. Descriptive statistics are based on observed values e.
A single outlier value with difference of days was removed from the figure for clarity. There were two methods of case identification and data collection performed separately, but in parallel, on the same group of out-of-hospital trauma patients. Author manuscript; available in PMC Feb 1. For manual methods, the time required per-record is fixed after maximizing the experience and speed of a given data abstractor and chart identification processes.
Overall, there were very similar characteristics generated from both data processing approaches. During the month period, patients underwent both data processing methods and formed the primary cohort. We compared values obtained from manual versus electronic data processing using nonparametric descriptive statistics median, interquartile range [IQR], and proportion.
During the month period, injured patients with physiologic compromise were identified, enrolled, cataloguw processed using manual data processing. In general, cases identified by manual methodology tended to selectornic greater physiologic compromise e.
For linking EMS records to patient discharge data, we used six variables date of service, date of birth, home zip code, age, sex, and hospital. These linkage variables included: RESULTS During the month period, injured patients with physiologic compromise were identified, enrolled, and processed using manual data processing. Electronic transformers — Tridonic — Data sheets Mortality rates are based on observed values.
Probabilistic linkage has been used previously to match EMS and police records to ED and hospital data sources, 89 and has been validated in our system using EMS and trauma databases.

We evaluated these strategies using three aspects of data collection and processing: These results will need caatalogue be replicated in a clinical trial setting to validate our results in an interventional research environment, including the timeliness of hospital outcomes and safety information. Co-Design of Systems and Applications for Exascale: In this study, we compare and contrast several eelectronic of data collection and processing among a cohort of out-of-hospital trauma patients using two separate strategies: Variables We evaluated 18 clinical, operational, procedural, and outcome variables obtained using each data processing strategy.
Conclusions In this sample of out-of-hospital trauma patients, an all-electronic data processing strategy identified more patients and generated values with good agreement and validity compared to traditional data collection xelectronic processing methods. Third, electronic data processing was based on aggregate data exports and processing routines that can handle large volumes of records with relatively small additional increases in processing time.
