accurate prediction of the surgical outcome is important in treating dentofacial deformities. visualized treatment objectives usually involve manual surgical simulation based on tracing of cephalometric radiographs. recent technical advancements have led to the use of computer assisted imaging systems in treatment planning for orthognathic surgical cases. the purpose of this study was to examin...

introduction: medication errors are among the most serious health errors threatening patient safety in all countries, with major impacts on public health. midwives as members of healthcare systems are prone to such errors. therefore, in this study, we aimed to determine medication errors and the contributing factors among midwives working in maternity units of mashhad university of medical scie...

When a clinical trial of an analgesic produces a negative finding, it is important to consider the influence (if any) of experimental error on the validity of that result. Although efforts to identify and minimize experimental error in chronic pain investigations have begun in earnest, less work has been performed on the optimization of acute pain methodology. Of the acute surgical pain methodo...

OBJECTIVE To evaluate the reliability and accuracy of computer-designed surgical guides in osseointegrated oral implant rehabilitation. MATERIALS AND METHODS Six implant rehabilitations, with a total of 17 implants, were completed with computer-designed surgical guides, performed with the master model developed by muco-compressive and muco-static impressions. In the first case, the surgical g...

BACKGROUND Communication errors are the primary factor contributing to all types of sentinel events including those involving surgical patients. One type of communication error is mislabeled specimens. The extent to which these errors occur is poorly quantified. We designed a study to measure the incidence and type of specimen identification errors in the surgical patient population. METHODS ...

BACKGROUND Several authors have suggested that the traditional surgical morbidity and mortality meeting be developed as a tool to identify surgical errors and turn them into learning opportunities for staff. We report our experience with these meetings. METHODS A structured template was developed for each morbidity and mortality meeting. We used a grid to analyse mortality and classify the de...

BACKGROUND Legislative measures have been identified as one effective way of changing attitude or behaviour towards health care. The aim of this study was to describe trends in patients' complaints for medical issues; to evaluate the contribution of a law regarding patients' rights, and to identify factors associated to patients' perception of a medical error. METHODS Patients with a complain...

A method is presented for incorporating error correction using a minimum distance measure into LR parsers. The method is suitable for use by an automatic parser-generator. State information in the LR parser stack at the point of detection of error is used to generate a set of strings which are potential repairs to the input. A string with least minimum distance from the actual input is chosen a...

Abstract Introduction Microsoft HoloLens® is an augmented-reality headset which increasingly used for surgical guidance. This allows the overlay of patient-specific virtual models obtained from medical images onto patient’s body surface using automatic marker-based alignment. can guide surgeons during certain tasks, e.g. determining biopsy needle entry points. study aims to measure human error ...
