“…In most developed settings, syndromic data is automatically retrieved from electronic systems, encrypted, archived, and processed at a secure facility, combing free text and structured electronic medical record entries [12], [27], [28],[29],[30]. Although computer and Internet use are rapidly increasing in rural China, medical records of patients’ main symptoms or chief complaints, are paper-based in most health facilities [22].…”

Backgroundsyndromic surveillance system has great advantages in promoting the early detection of epidemics and reducing the necessities of disease confirmation, and it is especially effective for surveillance in resource poor settings. However, most current syndromic surveillance systems are established in developed countries, and there are very few reports on the development of an electronic syndromic surveillance system in resource-constrained settings.Objectivethis study describes the design and pilot implementation of an electronic surveillance system (ISS) for the early detection of infectious disease epidemics in rural China, complementing the conventional case report surveillance system.MethodsISS was developed based on an existing platform ‘Crisis Information Sharing Platform’ (CRISP), combining with modern communication and GIS technology. ISS has four interconnected functions: 1) work group and communication group; 2) data source and collection; 3) data visualization; and 4) outbreak detection and alerting.ResultsAs of Jan. 31st 2012, ISS has been installed and pilot tested for six months in four counties in rural China. 95 health facilities, 14 pharmacies and 24 primary schools participated in the pilot study, entering respectively 74256, 79701, and 2330 daily records into the central database. More than 90% of surveillance units at the study sites are able to send daily information into the system. In the paper, we also presented the pilot data from health facilities in the two counties, which showed the ISS system had the potential to identify the change of disease patterns at the community level.ConclusionsThe ISS platform may facilitate the early detection of infectious disease epidemic as it provides near real-time syndromic data collection, interactive visualization, and automated aberration detection. However, several constraints and challenges were encountered during the pilot implementation of ISS in rural China.

“…There are additional layers of complexity introduced with chief complaint classification in multilingual settings, as the expression of chief complaint may vary between languages and cultures or where lack of familiarity with the health care encounter can limit a patient's ability to articulate the problem to a provider. There is a need for harmonization of chief complaint concepts across cultural divides to conduct regional and global emergency care research.…”

Making Recording and Analysis of Chief Complaint a Priority for Global Emergency Care Research in Low‐income Countries

The chief complaint is a patient's self-reported primary reason for presenting for medical care. The clinical utility and analytical importance of recording chief complaints have been widely accepted in highly developed emergency care systems, but this practice is far from universal in global emergency care, especially in limited-resource areas. It is precisely in these settings, however, that the use of chief complaints may have particular benefit. Chief complaints may be used to quantify, analyze, and plan for emergency care and provide valuable information on acute care needs where there are crucial data gaps. Globally, much work has been done to establish local practices around chief complaint collection and use, but no standards have been established and little work has been done to identify minimum effective sets of chief complaints that may be used in limited-resource settings. As part of the Academic Emergency Medicine consensus conference, "Global Health and Emergency Care: A Research Agenda," the breakout group on data management identified the lack of research on emergency chief complaints globally-especially in low-income countries where the highest proportion of the world's population resides-as a major gap in global emergency care research. This article reviews global research on emergency chief complaints in high-income countries with developed emergency care systems and sets forth an agenda for future research on chief complaints in limited-resource settings.ACADEMIC EMERGENCY MEDICINE 2013; 20:1241-1245 by the Society for Academic Emergency Medicine A ny analysis of emergency care must take account of a fundamental aspect of the presentation itself: the chief complaint. Despite the fact that the chief complaint is "the patient's reason for seeking care or attention, expressed in terms as close as possible to those used by [the] patient or responsible

“…In addition to medical information needs, other proposals aim to analyze administrative data and reports to assess complaints [25], emergency room use [26] or quality measures [27]. While these systems also apply NLP techniques, they do not match this analysis to medical knowledge bases or corpora because they are centered on administrative data.…”

Objective: Electronic medical records (EMR) typically contain both structured attributes as well as narrative text. The usefulness of EMR for research and administration is hampered by the difficulty in automatically analyzing their narrative portions. Accordingly, this paper proposes SPIRE, a strategy for prioritizing EMR, using natural language processing in combination with analysis of structured data, in order to identify and rank EMR that match specific queries from clinical researchers and health administrators. Materials and Methods: The resulting software tool was evaluated technically and validated with three cases (heart failure, pulmonary hypertension and diabetes mellitus) compared against expert obtained results. Results and Discussion: Our preliminary results show high sensitivity (70%, 82% and 87% respectively) and specificity (85%, 73.7% and 87.5%) in the resulting set of records. The AUC was between 0.84 and 0.9. Conclusions: SPIRE was successfully implemented and used in the context of a university hospital information system, enabling clinical researchers to obtain prioritized EMR to solve their information needs through collaborative search templates with faster and more accurate results than other existing methods.
