“…It is also observed that minimal solutions have been proposed for network resiliency and offer data routing in a non-optimal manner in terms of longer constancy and heavy sensor traffic. Therefore, the research community is still focused on presenting a resilient approach to coping with data management integrated cloud systems to overcome vulnerabilities in the healthcare system and help patients and medical professionals [37][38][39][40].…”

Nowadays, the Internet of Things (IoT) performs robust services for real-time applications in monitoring communication systems and generating meaningful information. The ZigBee devices offer low latency and manageable costs for wireless communication and support the process of physical data collection. Some biosensing systems comprise IoT-based ZigBee devices to monitor patient healthcare attributes and alert healthcare professionals for needed action. However, most of them still face unstable and frequent data interruption issues due to transmission service intrusions. Moreover, the medical data is publicly available using cloud services, and communicated through the smart devices to specialists for evaluation and disease diagnosis. Therefore, the applicable security analysis is another key factor for any medical system. This work proposed an approach for reliable network supervision with the internet of secured medical things using ZigBee networks for a smart healthcare system (RNM-SC). It aims to improve data systems with manageable congestion through load-balanced devices. Moreover, it also increases security performance in the presence of anomalies and offers data routing using the bidirectional heuristics technique. In addition, it deals with more realistic algorithm to associate only authorized devices and avoid the chances of compromising data. In the end, the communication between cloud and network applications is also protected from hostile actions, and only certified end-users can access the data. The proposed approach was tested and analyzed in Network Simulator (NS-3), and, compared to existing solutions, demonstrated significant and reliable performance improvements in terms of network throughput by 12%, energy consumption by 17%, packet drop ratio by 37%, end-to-end delay by 18%, routing complexity by 37%, and tampered packets by 37%.

“…20 Motevali and Torabi improve hospital operating performance from the perspective of mixed sustainability and resilience. 21 The current domestic and international researches on the performance evaluation of pension services have achieved certain results, but there are still deficiencies. Most of the evaluation research on elderly care services focuses on home-based elderly care services, governmentpurchased elderly care services, and institutional elderly care services.…”

The aim of this paper was to build a performance evaluation index system for the combination of medical and old-age care services in pension institutions of China. Methods: A two-stage data envelopment analysis (DEA) is used to evaluate the performance of 30 pension institutions in China. Results:The results show that the two-stage DEA accounted for a relatively high affiance of medical and nursing care services, but resource allocation still needs to be further optimized. Institutions with ineffective DEA need to reduce the five factors of operations, management, fixed assets, technology and services in the input dimension. Conclusion:In the output dimension, the service evaluation effect and safety management effect need to be improved. The performance of combined old-age care and medical care in old-age institutions can be improved in terms of investment in fixed assets, methods of capital subsidies, supervision and management, as well as standardized operations.

“…Resilience refers to a system's ability to recover from and continue operations after unexpected events (Erol et al, 2010). A resilient information system can adapt positively to recover faster from the service disruptions brought by events such as data loss (Motevali Haghighi and Torabi, 2018). However, there is a tradeoff between the extent of system recovery and time to recovery (TTR) because operational recovery progresses in multiple phases (Bartock et al, 2016).…”

PurposeDelay in the clinical information system (CIS) restoration overseeing critical health-care operations after an unexpected data loss can be fatal for patients under care. Investment in information technology (IT) capabilities and synergy between various computerized systems has been argued as the resilient information system's enablers. The purpose of this study is to empirically quantify the influence of IT investment, integration and interoperability in recovering the CIS from a data disaster.Design/methodology/approachAn archival dataset sourced from a European Commission-sponsored survey of 773 hospitals across 30 countries in Europe is utilized to study the relationships. The study adopts a quasi-experimental research design approach where sample observations are weighted based on their propensity to be selected in treatment groups. The artificial weighing allows attaining a pseudo-random sample to counter the effects of selection bias.FindingsThe study finds that hospitals with more than 5% of the budget dedicated to IT have 100% higher odds of recovering immediately from a critical data loss in comparison to those that have less than 1% investment in IT. The greater extent of IT integration significantly reduces the time to recover the CIS, while interoperability problems at the organizational level lessen the odds of immediate recovery by 19%. Interoperability problems at the technical and semantic levels do not significantly impact recovery times of the CIS.Originality/valueThe study proposes several empirically quantified and scientifically tested recommendations for health-care providers for faster restoration of critical CIS operations post data loss. The differential impact of the interoperability problems at the technical, semantic and organizational levels has also been highlighted.
