OBJECTIVE To expand an emerging classification for problems with health information technology (HIT) using reports submitted to the US Food and Drug Administration Manufacturer and User Facility Device Experience (MAUDE) database. DESIGN HIT events submitted to MAUDE were retrieved using a standardized search strategy. Using an emerging classification(More)
OBJECTIVE To analyze patient safety incidents associated with computer use to develop the basis for a classification of problems reported by health professionals. DESIGN Incidents submitted to a voluntary incident reporting database across one Australian state were retrieved and a subset (25%) was analyzed to identify 'natural categories' for(More)
IMPORTANCE Epilepsy is a debilitating condition, often with neither a known etiology nor an effective treatment. Autoimmune mechanisms have been increasingly identified. OBJECTIVE To conduct a population-level study investigating the relationship between epilepsy and several common autoimmune diseases. DESIGN, SETTING, AND PARTICIPANTS A retrospective(More)
BACKGROUND Handoffs serve a critical function in ensuring patient care continuity during transitions of care. Studies to date have predominantly focused on intershift handoffs, with relatively little attention given to intrahospital transfers. A systematic literature review was conducted to characterize the nature of handoff failures during intrahospital(More)
Populationwide mammography screening has been associated with a substantial rise in false-positive mammography findings and breast cancer overdiagnosis. However, there is a lack of current data on the associated costs in the United States. We present costs due to false-positive mammograms and breast cancer overdiagnoses among women ages 40-59, based on(More)
OBJECTIVE To explore the applicability of a syndromic surveillance method to the early detection of health information technology (HIT) system failures. METHODS A syndromic surveillance system was developed to monitor a laboratory information system at a tertiary hospital. Four indices were monitored: (1) total laboratory records being created; (2) total(More)
The manner in which people preferentially interact with others like themselves suggests that information about social connections may be useful in the surveillance of opinions for public health purposes. We examined if social connection information from tweets about human papillomavirus (HPV) vaccines could be used to train classifiers that identify(More)
OBJECTIVE To model how individual violations in routine clinical processes cumulatively contribute to the risk of adverse events in hospital using an agent-based simulation framework. DESIGN An agent-based simulation was designed to model the cascade of common violations that contribute to the risk of adverse events in routine clinical processes.(More)
The objective of this paper is to analyze healthcare information technology (HIT) events associated with patient harm submitted to the US Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database. We examined the problems in 46 relevant events submitted to MAUDE from January 2008 to July 2010 to identify natural(More)
BACKGROUND The prevalence of asthma has increased alarmingly in the past 2 to 3 decades. Increased antibiotic use in infancy has been suggested to limit exposure to gastrointestinal microbes and to predispose to asthma in later life. OBJECTIVE To evaluate the association between antibiotic exposure during the first year of life and the development of(More)
