Radiology report errors occur for many reasons including the use of pre-filled report templates, wrong-word substitution, nonsensical phrases, and missing words. Reports may also contain clinical errors that are not specific to the speech recognition including wrong laterality and gender-specific discrepancies. Our goal was to create a custom algorithm to detect potential gender and laterality mismatch errors and to notify the interpreting radiologists for rapid correction. A JavaScript algorithm was devised to flag gender and laterality mismatch errors by searching the text of the report for keywords and comparing them to parameters within the study’s HL7 metadata (i.e., procedure type, patient sex). The error detection algorithm was retrospectively applied to 82,353 reports 4 months prior to its development and then prospectively to 309,304 reports 15 months after implementation. Flagged reports were reviewed individually by two radiologists for a true gender or laterality error and to determine if the errors were ultimately corrected. There was significant improvement in the number of flagged reports (pre, 198/82,353 [0.24 %]; post, 628/309,304 [0.20 %]; P = 0.04) and reports containing confirmed gender or laterality errors (pre, 116/82,353 [0.014 %]; post, 285/309,304 [0.09 %]; P < 0.0001) after implementing our error notification system. The number of flagged reports containing an error that were ultimately corrected improved dramatically after implementing the notification system (pre, 17/116 [15 %]; post, 239/285 [84 %]; P < 0.0001). We developed a successful automated tool for detecting and notifying radiologists of potential gender and laterality errors, allowing for rapid report correction and reducing the overall rate of report errors. 相似文献

Objective
To evaluate nurses’ triage quality and adequacy in Saragossa's Hospital Clínico and to compare the main characteristics of “urgent” and “non-urgent” visits to the Hospital Emergency Department (HED).Method
This exploratory-retrospective research study was carried out over the last 3 months of 2015 (paediatrics, gynaecological and ophthalmologic emergencies were excluded). Data were obtained from the “Puesto Clínico Hospitalario” programme used in the HED. The quality of the triage performed by nurses was assessed using the 4 indexes proposed by Gómez Jimenez and the adequacy of patient classification was established by relating the level of triage assigned with the place of care, length of stay in the HED and type of discharge. Differences between “non-urgent” (seen in outpatient consultations of the HED) and “urgent” visits were analysed,Results
22,047 individuals were included. Quality indices relating to waiting times were not fully met. Higher severity of triage was associated with being attended in the area of Vital and Medical Care, a longer stay in the HED and a higher proportion of hospital admissions (p < .001), so that triage performed by nursing is considered adequate. “Non-urgent” visits obtained less severity of triage, a shorter stay in HED and a greater proportion of hospital discharges (p < .001).Conclusions
Nursing triage needs to improve quality aspects related to waiting times but is appropriate enough as it discriminates between place of care and type of discharge for each level of triage within the desirable limits. 相似文献53.

Background
Emergency department (ED) crowding is associated with patient safety concerns, increased patients left without being seen (LWBS), low patient satisfaction, and lost ED revenue. The objective was to measure the impact of a revised triage process on ED throughput.Methods
This study took place at an urban, university-affiliated, adult ED with an annual census of 70,000 and admission rate of 34%. The revised triage approach included: identifying eligible patients at triage based on complaint, comorbidities, and illness acuity; and reallocating a nurse practitioner (NP) into our triage area. We trialed the intervention from 1100–2300 on weekdays from January 13–26, 2016. Adult patients who were not likely to require intensive evaluations were eligible. Primary outcomes were throughput measures including: time to provider, ED length of stay (LOS), and LWBS. Pre- and post-intervention metrics were compared using the Mann-Whitney U test, given the non-normal distribution of the metrics.Results
The NP evaluated 120 patients of which 101 (84%) were discharged, 3 (2.5%) admitted, and 16 (13%) required more intense evaluation. Time to provider decreased from a median (IQR) of 42 (16, 114) to 27 (12.4, 81.5) minutes (p < 0.01) and ED LOS from 290 (194.8, 405.6) to 257 (171.2, 363.4) minutes (p < 0.01) for all patients not admitted and not requiring a consult. LWBS decreased from a pre-trial 4.6% to 2.2% (p < 0.01).Conclusion
The revised triage intervention was associated with improvements in several ED throughput metrics and a reduction in LWBS. 相似文献57.
Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate (CAS Reg. No. 2082-79-3), currently marketed as Irganox 1076 (I-76), is a sterically hindered phenolic antioxidant used in a variety of organic substrates, including those used in the manufacture of food contact articles. In 2012, the US Food and Drug Administration (USFDA), Office of Food Additive Safety (OFAS), initiated a post-market re-evaluation of the food contact applications of I-76. This project aimed to ensure that current dietary exposures from the use of I-76 in food contact articles are accurately captured and the safety assessment considered all relevant and available toxicological information. To accomplish these aims, the USFDA reviewed the available toxicological studies and chemistry information on food contact applications of I-76. Based on this in-depth analysis, a NOAEL of 64 mg/kg-bw/d (female rats) from a chronic rat study and a cumulative estimated dietary intake (CEDI) of 4.5 mg/p/d, was used to calculate a margin of exposure (MOE) of ∼850. We concluded that the previous and current exposure levels provide an adequate margin of safety (MOS) and remain protective of human health for the regulated uses. 相似文献

BACKGROUND: Dysfunction of central serotonergic neurotransmission has been implicated in the pathogenesis and maintenance of alcoholism. Serotonergic dysfunction may be associated with three behavior patterns relevant for alcoholism: impulsive aggression, negative mood states, and a low response to alcohol intake. METHODS: We reviewed the literature on the psychopathological correlates of serotonergic dysfunction and focused on studies that assess the interaction between negative mood states and alcohol response. RESULTS: Prospective studies in nonhuman primates that underwent early separation stress found an association between a low serotonin turnover rate and the disposition to excessive alcohol intake and impulsive aggression. These findings seem to be relevant for a subgroup of alcoholics with a low serotonin turnover rate and antisocial personality traits. Cross-sectional data in humans also support a relationship between reduced serotonergic neurotransmission and aggressive behavior and indicate that the association of serotonergic dysfunction and aggression may be mediated by negative mood states. This hypothesis is in accordance with a large body of data linking anxiety and depression to serotonergic dysfunction. In human alcoholics, brain imaging has detected a reduction in serotonin transporter availability in association with depression. Serotonin transporter availability seems to be related to reduced GABA-ergic sedation and the acute response to alcohol intake, an important predictor of subsequent development of alcohol dependence. CONCLUSIONS: Several lines of evidence point to a relationship between serotonergic dysfunction, negative mood states, and excessive alcohol intake, which may be mediated in part by reduced alcohol-induced sedation. 相似文献
