E-Cart Design for Controlling Cart Abandonment in E-Commerce: A Conjoint Experiment

This study attempted to understand the most important attributes and their preferred levels of an e-shopping cart for maximum utility perceptions by e-commerce customers. The research has significance in the backdrop of observations that online customers have multiple sorts of hesitation on purchase completions, and their cart abandonment tendencies are causing serious challenges to e-commerce firms across the world. Assuming that better e-cart design can minimize cart abandonment intentions, an eight attribute conjoint experiment with a total of nineteen levels was conducted to decide on an optimum cart design. The experiment concluded that online customers prefer an order summary page with product images, add to cart option without login, live chat feature in cart; add to cart button on both sidebar and top of the page; online payment options, security logo and social proof in e-cart, purchase history review option in the cart page, and delivery progress tracking bar in the cart page itself.

997. Practical partnering of Antibiotic Stewardship and Allergy to address referrals to Penicillin allergy debunking clinic at a VA Medical Center

Background The majority of Penicillin (PCN) allergies can be “debunked.” During acute medical care, opportunities to refer for formal evaluation are often overlooked, hampered by medication-interactions and lack of time and resources for bedside testing. Frequently, inpatients are not referred for PCN debunking evaluations (PCN-DE). Antimicrobial Stewardship Teams (ASTs) who partner with Allergy Clinical Teams (ACTs) can work collaboratively to target those who would benefit from de-labeling and are unlikely to otherwise be referred for formal evaluation. Methods The DCVAMC is an urban 240 bed 1a complexity acute and LTC teaching hospital with both on-site AST and well-established ACT. β-lactam allergy was tracked by the AST in inpatient, outpatient and long-term care setting utilizing a clinical surveillance system (TheraDoc, DSS Inc.) and allergy education was incorporated into prospective auditing rounds. PCN-DE involved face-face visit with an Allergist and careful history, chart/medication review. Option for skin testing (Pre-Pen, ALK Abello) with/without oral challenge performed at the discretion of ACT. EMR was altered to reflect results. Results We collaborated to develop a PCN-DE outpatient Allergy Clinic on the hospital campus. 2,564 designed β-lactam allergy alerts were identified as part of routine AST workflow prior to the initiation of the clinic in October 2017. Referrals resulted from AST prospective audits, consults to ACT and by surveillance of historical allergy history among acute and LTC admissions. Providers, including trainees, were engaged through education and encouraged to place outpatient referrals at the time of discharge or upon follow-up. ACT evaluated patients in groups of 2–3/session, roughly one clinic/month. Mean age of patients tested 56.3y (24–80y) with 35% >65yo; to date, (19/26) 73% have been successfully de-labeled Conclusion The success in de-labeling after formal evaluation is well established. Developing working relationships with allergists and encouraging providers to recognize often overlooked opportunities to refer to existing or newly established clinics is easily adopted by ASTs. In conjunction with screening, targeted education and referral to PCN-DE as a part of routine stewardship workflow has practical and immediate benefits.

Investigating Confidence Judgments using Reviews in Human and Monkeys

Confidence judgments are self-assessments of the quality of one’s own performance, and are a crucial aspect of metacognitive abilities. The underlying neurobiological mechanisms are poorly understood. One approach to understanding these mechanisms would be to take advantage of putative metacognitive abilities in non-human models. However, many discrepancies exist between human and non-human studies on metacognition due to the mode of reporting judgements. We here present an attempt to directly compare human and non-human primates’ metacognitive abilities using a protocol assessing confidence judgments. After performing a categorization test, subjects could either validate their choice or review the test. We could assess whether subjects detected their errors and how they corrected them according to their confidence, and importantly did so in both human and non-human primates. 14 humans and 2 macaque monkeys were tested. Humans showed a well-adapted use of the review option by reviewing more after incorrect choices or difficult stimuli. Non-human primates did not demonstrate a convincing use of the review or validate opportunity. In both species, reviewing did not improve performance. This study shows that decisions to review under uncertainty are not naturally beneficial to performance and is rather perturbed by biases and alternative low-cognitive cost strategies.
