Perioperative inhaled corticosteroids treatment is associated with decreased length-of-stay and direct medical costs in high-respiratory-risk surgeries

Abstract

Aims: To examine the impact of perioperative inhaled corticosteroids (ICS) on length-of-stay (LOS) and costs among patients receiving high-respiratory-risk surgeries.

Methods: Adult patients who underwent high-respiratory-risk surgeries in 2015 were identified in the Tianjin Urban Employee Basic Medical Insurance database. Patients were grouped into ICS or non-ICS cohorts according to whether they received ICS during the perioperative period of the index hospitalization. Propensity Score Matching was performed to create matched pairs between two cohorts. The impact of perioperative ICS on LOS and direct medical costs was estimated by negative binomial model and generalized liner model.

Results: Eight hundred and twenty-one hospital stays with high-respiratory-risk were selected in the ICS cohort and another 821 stays in the non-ICS cohort were matched. The mean LOS was 13.0 (±0.3) days in the ICS cohort, which was significantly lower than the matched non-ICS cohort. Patients with thorax and ear-nose-throat surgeries had a significant decrease in LOS in the ICS cohort compared to the non-ICS cohort, with a mean decrease of 5.5 and 1.1?days, respectively. In adjusted analyses, perioperative ICS treatment was associated with shorter LOS, lower total, and respiratory-related costs (reductions of 10.1%, 7%, and 5.3%, respectively) after controlling for demographic, clinical, and hospital characteristics.

Limitations: Some respiratory risk factors such as living behavior and environment were unable to be captured and respiratory-related costs might be underestimated, limited by claim data. Lastly, caution should be taken when generalizing the results to other populations, as only patients with moderate-to-severe surgeries on the thorax and above were selected in this study.

Conclusions: Perioperative ICS treatment was associated with decreased LOS and lower costs for patients undergoing high-respiratory-risk surgeries in China.     

企业全面预算管理问题及改进

双元联盟网络如何影响突破式创新——技术能力与网络惯例的调节作用

不同类型联盟网络涉及不同程度的知识共享和知识泄露风险,并有可能对突破式创新产生差异化影响。选取合肥、南京和苏州253个企业为样本,探究企业探索性联盟网络和开发性联盟网络分别对突破式创新的直接效应,以及技术能力和网络惯例等内外部情境变量对两种关系的调节效应。结果发现：探索性联盟网络对突破式创新具有倒U型效应;开发性联盟网络对突破式创新不具有曲线效应,仅是正向线性关系;内外部不同情境变量对探索性、开发性联盟网络具有不同调节效应。其中,技术能力仅对探索性联盟网络与突破式创新间关系具有显著正向调节作用;网络惯例对开发性联盟网络与突破式创新间关系具有显著正向调节作用。研究结论对组建企业联盟和推动企业技术创新发展具有一定指导意义。     

高技术企业多元化战略对创新持续性的影响——动态能力的调节作用

基于资源基础理论和持续创新内生机制,利用435家高技术企业2010—2018年面板数据,对多元化战略对高技术企业创新持续性的影响进行探究。结果表明,产品多元化与创新持续性呈正U型关系,技术多元化对创新持续性具有正向促进作用,产品多元化与技术多元化协同效应对创新持续性具有负向影响;动态能力强化了产品多元化与创新持续性之间的正U型关系,并正向调节技术多元化与创新持续性之间的关系。在动态能力调节作用下,高技术企业产品多元化与技术多元化协同效应对创新持续性具有正向影响。     

城市群高质量发展的理论逻辑与路径选择

现代化后发赶超要求以城市群作为主体空间形态,实现效率增进、功能跃升、均衡发展和开放合作.城市群正日益成为托起中国现代化的巨擘,目前我国19个城市群之间规模结构差异较大,以东部城市群发展质量最高.城市群发展失衡的原因在于,城市群城镇体系不合理、公共服务一体化存在障碍、区域一体化发展体制机制有待健全、城际间综合交通网络体系亟待完善.适应现代化发展要求,我国需要在城市群加快推动形成快速便捷的综合交通体系与一体化发展体制机制,以都市圈为载体优化城市群空间格局与推动城市群协同发展,加快构建包容共享的公共服务体系,提升城市群的开放发展水平,引领中国现代化发展.

Measuring agricultural knowledge and adoption

Understanding the tradeoffs in improving the precision of agricultural measures through survey design is crucial. Yet, standard indicators used to determine program effectiveness may be flawed, and at a differential rate for men and women. We use a household survey from Mozambique to estimate the measurement error from male and female self‐reports of their adoption and knowledge of three practices: intercropping, mulching, and strip tillage. Despite clear differences in human and physical capital, there are no obvious differences in the knowledge, adoption, and error in self‐reporting between men and women. Having received training unanimously lowers knowledge misreports and increases adoption misreports. Other determinants of reporting error differ by gender. Misreporting is positively associated with a greater number of plots for men. Recall decay on measures of knowledge appears prominent among men but not women. Findings from regression and cost‐effectiveness analyses always favor the collection of objective measures of knowledge. Given the lowest rate of accuracy for adoption was around 80%, costlier objective adoption measures are recommended for a subsample in regions with heterogeneous farm sizes.     

Local competition, entry, and agglomeration

This paper analyzes competition between two spatially differentiated multi-product retailers who encounter entry from a low-cost discounter. We assess how entry affects the pricing of the incumbent stores and the role played by the location of the entrant. Our primary objective is to identify how traditional retailers respond to new forms of low-cost retailing. Results show that post entry, the prices for some products are higher than the pre entry. However, which product prices increase depends on the incumbent’s location. Contrary to conventional wisdom, we find that the store closer to the entrant is better off compared to the incumbent located further away. We empirically demonstrate the main workings of our theory using sales data from several grocery stores that saw entry by discount stores in their trading areas.
