SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study
Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in su…
Determinants of customer retention in virtual environments. The role of perceived risk in a tourism services context
Abstract The aim of this paper is to determine whether perceived risk moderates the antecedents of customer retention in online travel purchasing or, whether, on the contrary, those antecedents explain predisposition to repeat purchase from a website, whatever the level of risk. The impact of perceived risk as a moderator of the influence of website reputation, consumer trust in the site and user satisfaction with the shopping experience on repurchase intention was tested through structural equation modelling techniques and multigroup analysis on a sample of 455 Internet purchasers of tourist accommodation. Data analysis confirms the role of satisfaction and website reputation as builders o…
