Improving the rate of pathogen examination before antibiotic treatment is of great significance for clarifying pathogen diagnosis and curbing bacterial resistance, and is also one of the important goals for improving national medical quality and safety. In response to the current problem of low pathogen examination rates, Chengdu Women’s and Children’s Central Hospital adopts a FOCUS-PDCA model, has explored measures such as current situation investigation, root cause analysis, intervention plan formulation, countermeasure implementation, and effect evaluation to improve the rate of pathogen examination before antibiotic treatment in inpatients. This article mainly elaborates on the above model, which has practical significance for ensuring the rational use of antibiotics in inpatients.
ObjectiveTo use failure mode and effect analysis (FMEA) to check and improve the risk of severe acute respiratory syndrome coronavirus 2 nucleic acid detection, and explore the application effect of FMEA in the emergency inspection items.MethodsFMEA was used to sort out the whole process of severe acute respiratory syndrome coronavirus 2 nucleic acid detection from January 30 to February 21, 2020. By establishing the theme, setting up a team, analyzing the failure mode and potential influencing factors. Then calculate the risk priority number (RPN), formulate preventive measures and implement continuous improvement according to the analysis results.ResultsA total of 2 138 cases were included. After improvement, the number of potential failure modes has been reduced by 2 (17 vs.19); the value of total RPN decreased (3 527.49 vs. 1 858.28). There was significant difference in average RPN before and after improvement [(185.66±74.34) vs. (97.80±37.97); t=6.128, P<0.001].ConclusionsIn the early stage of emergency inspection items, using FMEA can systematically check the risk factors in the process, develop improvement measures. It also can effectively reduce the risk of severe acute respiratory syndrome coronavirus 2 nucleic acid detection in hospital.
Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is a peripheral retinal disease characterized by subretinal hemorrhage and/or subretinal pigment epithelial hemorrhage or exudation. It is often misdiagnosed as age-related macular degeneration, polypoidal chorioretinopathy or choroidal melanoma. With the development of multimodal imaging, PEHCR has different features under different examinations, such as B-scan ultrasound, fluorescein fundus angiography, optical coherence tomography and so on, which contributes to differention from other diseases. Clinical treatments for the disease include intravitreal injection of retinal photocoagulation therapy, anti-vascular endothelial growth factor, pars plana vitrectomyand so on, but there is still no universal consensus. In order to gain a deeper understanding of the clinical features, treatment options and prognosis of PEHCR, minimize missed diagnoses and misdiagnoses, and improve treatment efficiency, further research is required.

Objective To observe the clinical and multimodel image features in patients of acute macular neuroretinopathy (AMN) associated with COVID-19. MethodsClinical data and multimodal imaging results in 12 patients (24 eyes) of AMN associated with COVID-19 which were diagnosed in our Department of Ophthalmology, The Second Hospital of The Army Medical University ranging from December 2022 to January 2023 were included. All patients were examined by best-corrected visual acuity (BCVA), color fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), visual field tests, high-resolution computed tomography of the lungs and inflammation-related laboratory tests. After diagnosis, patients were reveived methylcobalamin and Ginaton therapy, 6 patients receiced intravenous dripping of dexamethasone. The follow-up time of this study was 4 weeks. ResultsThere were 1 male (2 eyes) and 11 females (22 eyes), with the mean age of (29.00±5.17) years. For all cases, decreased vision presented 1 to 2 days after patients being suffered from several flu-like symptoms of COVID-19. Ten eyes in 5 patients were at the acute phrase of AMN, which the vision decrease occurred 1-5 days after they were diagnosed with COVID-19; 14 eyes in 7 patients were at the progressive stage of AMN, which they were diagnosed with COVID-19 for more than 5 days. The BCVA of patients were 0.02-0.9, in company with one or more central/pericentral scotoma. Fundus ophthalmoscopy revealed reddish-brown lesion around macula, IR imaging demonstrated localized areas of hypo-shape lesions in the macula. For 16 eyes, their OCTA revealed a decreased density of blood flow in the deep layer of retinal capillary plexus, and OCT revealed that high reflex bands existed in the outer nuclear layer (ONL) and outer plexiform layer of the retina at the acute phrase of AMN, in accompany with hypo-reflection in ellipsoid zone (EZ) and interdigitation zone (IZ); for retina at the progressive stage of AMN, ONL became thinner in some cases and the continuation interruption occurred in EZ and IZ. For en-face OCT, high reflex bands with clear edges existed in the ONL and EZ layer of the retina at the acute phrase of AMN, but no high reflex bands existed in the ONL and EZ layers of the retina at the progressive stage of AMN. Instead, hypo-reflection with similar shape occurred in the EZ and IZ layers at the progressive stage of AMN. During treatment, 5 patients at the acute phrase reported a shrinking central scotomas and raised BCVA, otherwise the BCVA of 7 patients at the progressive stage changed slightly. For 10 eyes at the acute phrase of AMN, OCT revealed that the high reflex bands of ONL and OPL missed within 1 week. En-face OCT revealed the hyper-reflection in the ONL and EZ layers of retina in the acute phrase of AMN receded within 1 week, but hypo-reflection of ONL and EZ still presented. ConclusionsFor AMN associated with COVID-19, IR imaging demonstrated localized areas of hypo-shape lesions in the macula. OCT revealed high reflex bands in ONL and OPL of the retina at the acute phrase of AMN, but hypo-reflection of ONL and EZ still presented. The continuation interruption occurred in EZ and IZ at the progressive phrase. En-face OCT revealed hyper-reflection in ONL and EZ of the retina at the acute phrase which receded within 1 week, and hypo-reflection in EZ and IZ of the retina presented at all phrases during AMN progression.

With high morbidity, branch retinal vein occlusion (BRVO) is a common retinal vascular disease in the clinic. Although the classic characteristics of BRVO have been recognized for a long time, the traditional understanding of BRVO has been challenged along with development and application of new imaging technologies, including the reasonable classification and staging of the disease, and the vascular characteristics at the occlusive site via multimodal imaging, etc. Thus, re-summarizing and refining these features as well as further improving and optimizing traditional imaging evaluation, can not only deepen the correct acknowledge of the entity, but also find biomarkers of prognosis of visual function, which is helpful to establish better diagnosis and treatment strategy. In the meanwhile, it is necessary that clinical characteristics of BRVO on imaging and the reliability of these imaging techniques are worth correct understanding and objective assessment.
