Beach nourishment has been widely used for beach protection around the world. However, there is limited information about beach nourishment in China. This study offers an overview of beach nourishment practices, status and technological advances in China, based on the literature, reports, and personal communications. The results demonstrate that beach nourishment has been recognized as an effective and environmentally friendly measure to combat coastal erosion and has been increasingly adopted in China, especially in the past decade. The unique characteristics of coastal China resulted in a difference in beach nourishment between China and Western developed countries in terms of the types, objectives, and shapes of beach nourishment. For the types of nourishments in China, there were approximately the same number of restored beaches and newly constructed beaches. For fill sediment, homogeneous fill and heterogeneous fill comprised 51.1% and 48.9% of projects, respectively. The objective of beach nourishment was mainly to promote coastal tourism, and the shape of nourished beaches was dominated by headland bays. This study also indicated that China has achieved a number of technological advances in beach nourishment, including methods of beach nourishment on severely eroded coasts and muddy coasts, an optimized design of drain pipes involved in urban beaches, and ecological design considerations. From the past decade of practices, four aspects were proposed as considerations for future nourishment: sand sources, technique advances, ecological effects, and management of beach nourishments.

Successful Reduction

Background: Inappropriate ordering of urine cultures and the resulting unnecessary use of antibiotics can lead to complications of antimicrobial therapy including resistance, adverse effects (eg, disruption of microbiome and C. difficile infection), and increased healthcare costs, as well as the erroneous determination of CAUTI in patients with Foley catheters. A retrospective analysis of patients with CAUTI revealed frequent ordering of urine cultures for conditions and symptoms not supported by current IDSA guidelines. As a result, we created an action plan to reverse the trend of inappropriate urine culture ordering. Methods: Our urine culture reduction campaign was developed with input from the infectious disease service, antibiotic stewardship team (AST), infection prevention, pharmacy, and the microbiology service. The following educational efforts were included: (1) distribution of outpatient pocket cards with communication to providers about appropriate ordering of urine cultures; (2) creation of an evidence-based order set for urinalysis and urine cultures distributed electronically as emails and screensavers on computer stations and in person via didactic sessions with physicians and nursing staff; (3) a practice pointer for staff nurses that included recommended changes to urine culture ordering and encouraged open dialogue with physicians regarding the appropriateness of urine cultures; (4) didactic and personal communications to counter long-standing myths, such as “Urine cultures always for change in mental status”; (5) a peer-review process to evaluate and justify deviations from the testing algorithm.Results: The first and second months after the introduction of the campaign, the microbiology laboratory reported 23% and 37% reductions in urine cultures ordered, respectively. During the same period, a 48% reduction in CAUTIs was reported for the entire health system. Conclusions: Reducing the number of inappropriate urine cultures is achievable with intense communication utilizing a multifaceted approach. With continued educational activities, we expect to sustain and even improve our successful reduction of inappropriate urine culture orders, ultimately improving patient outcomes.Funding: NoneDisclosures: None
