Several hearing aid prescription procedures specify frequency gain functions in terms of the desired levels of amplified speech. The most direct method for verifying hearing aid fittings based on these procedures requires a measurement of amplified speech in the ear canal. This paper describes the evaluation of a probe microphone measurement procedure designed to measure amplified speech to ver...

BACKGROUND Relatively little is known about the incidence of prescribing errors and there has been no work on this in a single specialty ophthalmic hospital. Knowing where and when errors are most likely to occur is generally felt to be the first step in trying to prevent these errors. This study is an attempt in, the setting of an eye hospital, to try to identify and attribute these medication...

OBJECTIVES We investigated incidence rates to understand the nature of medication errors potentially introduced by utilizing a computerized physician order entry (CPOE) system in the three clinical phases of the medication process: prescription, administration, and documentation. METHODS Overt observations and chart reviews were employed at two surgical intensive care units of a 950-bed terti...

OBJECTIVES Prescription of excessive doses is the most common prescription error, provoking dose-dependent adverse drug reactions. Clinical decision support systems (CDSS) can prevent prescription errors especially when mainly clinically relevant warnings are issued. We have built and evaluated a CDSS providing upper dose limits personalised to individual patient characteristics thus guaranteei...

Legal ignorance typically refers to a situation where one is ignorant of the existence certain legal prescript or precise understanding its consequences. In Belgian law, there no general provision dealing with effects. principle, cannot escape application law based on mere fact that does not know However, in specific situations and case deviate from this basic provided strict conditions are ful...

purpose: to evaluate the incidence of medication error in patients who underwent intraocular surgery based on different methods of drug instruction (hand-written versus orally explained) at labbafinejad medical center. methods: during a 6-month period, we evaluated 204 postoperative patients who underwent cataract or glaucoma surgery. patients were randomly assigned to two groups; in group i, p...

The National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP) defines a "medication error" as "any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of the health care professional, patient, or consumer. At many occasions a medication error can be caught or is rectified before its administ...

BACKGROUND Inappropriate antibiotic (ATB) prescriptions are a threat to patients, leading to adverse drug reactions, bacterial resistance, and subsequently, elevated hospital costs. Our aim was to evaluate ATB prescriptions in an emergency department of a tertiary care facility. METHODS A cross-sectional study was conducted by reviewing charts of patients complaining of infections. Patient ch...

Quantum operations provide a general description of the state changes allowed by quantum mechanics. The reversal of quantum operations is important for quantum error-correcting codes, teleportation, and reversing quantum measurements. We derive information-theoretic conditions and equivalent algebraic conditions that are necessary and sufficient for a general quantum operation to be reversible....

OBJECTIVE assess the safety of medication dispensing processes through the dispensing error rate. METHOD Cross-sectional study carried out at a pharmaceutical service of a pediatric hospital in Espírito Santo, Brazil. Data collection was performed between August and September 2006, totaling 2620 prescribed medication doses. Any deviation from the medical prescription in dispensing medication ...
