Identifying computerized provider order entry (CPOE) medication errors.
Computerized provider order entry (CPOE) can help reduce the occurrence of medication errors. In Saudi Arabia, CPOE has been implemented for years, with a small number of studies evaluating the impacts of CPOE on medication errors. ⋯ Data was reviewed and evaluated to identify and analyze all drug prescribing errors and subsequently exploring factors that have contributed to the identification of the drug prescribing errors by the dispensing pharmacists. Recommendations on developing policies and procedures, working in a safe environment, healthcare provider awareness, and improved technology to reduce medication errors in Saudi Arabia are discussed.

A domain-based approach for retrieving trustworthy health videos from YouTube.
Health information retrieval and YouTube can be used as powerful tools to improve user's health knowledge. However, YouTube videos must be carefully analysed in order to avoid misleading, inaccurate, obsolete and incorrect health content. ⋯ Video and channel metadata are used to automatically determine if a video is provided by a trusted source. The approach is tested and results show that the amount of relevant and reliable videos ranked within top-10 increase when using Domain-based ranking, compared with the original YouTube ranking.

Engineering natural language processing solutions for structured information from clinical text: extracting sentinel events from palliative care consult letters.
Despite a trend to formalize and codify medical information, natural language communications still play a prominent role in health care workflows, in particular when it comes to hand-overs between providers. Natural language processing (NLP) attempts to bridge the gap between informal, natural language information and coded, machine-interpretable data. This paper reports on a study that applies an advanced NLP method for the extraction of sentinel events in palliative care consult letters. ⋯ A random selection of 215 anonymized consult letters was used for the study. The results of the NLP extraction were evaluated by comparison with coded sentinel event data captured independently by clinicians. The average accuracy of the automated extraction was 73.6%.

Handheld technology finds slowly its place in the healthcare world. Some clinicians already use intensively dedicated mobile applications to consult clinical references. However, handheld technology hasn't still broadly embraced to the core of the healthcare business, the hospitals. ⋯ To answer these questions, we have set up a field study to compare users' performances on three different user interfaces while recording vital signs. Some user interfaces were familiar to users, and others were totally innovative. Results showed that users' familiarity with smartphone influences their performances and that users improve their performances by repeating a task.

Utilizing electronic health record data to determine the health of the medication process after the relocation of a children's hospital.
Hospital relocation is a highly complex undertaking, which has the potential to interrupt operations and poses risks for patients, staff, and providers. Little is known how hospital relocation impacts on workflow and communication. ⋯ Overall performance of the medication process has declined slightly. We identified regional (unit) differences with the pediatric intensive care unit, which had the most significant changes to its workflow, experiencing a more than doubling of the time from ordering to medication administration. Overall, there was no significant difference in time-sensitive medication administration times. Evaluating the medication ordering-dispensing-administration process through readily available EHR data demonstrated that the impact of a hospital' s relocation on workflow and communication can be successfully monitored.
