This work proposes an approach based on mining clinical data to support the exploration of health trajectories related to cardiovascular diseases. As the health data are highly confidential, we aimed to conduct our experiments using a large, synthetic, longitudinal dataset, constituted to represent the CVD risk factors distribution and temporal sequence of events related to heart failure hospitalization and readmission. This research work analyses and represents the temporal events or states of the patient's trajectory with the aim of understanding the patient's journey in the management of the chronic condition and its complications by using data mining techniques. This study focuses on developing an efficient algorithm to find cohesive clusters for handling the temporal events. Clustering health trajectories have been carried out by proposing an improved version of the Ant-based clustering algorithm. Insights from this study can potentially result in evidence that these approaches are useful in understanding and analyzing patient's health trajectories for better management of the chronic condition and its progression.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"02 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129009368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, BYOD also means that healthcare organisations are at great risk of leaking sensitive information assets like Personal Health Information (PHI) of patients, given that personal devices are outside the control of hospital IT management and may lack important security measures. Hence, the aim of this research is to develop a mitigation strategy which can cater to such security issues. A comprehensive literature review was conducted to identify BYOD security issues and mitigation solutions. This was followed by using two existing security frameworks, the BYOD security framework and People Policy Technology (PPT) model to shape a stepwise mitigation strategy. Technical, managerial and social issues were identified which include unsecure user behaviour by hospital employees, lack of security awareness, usability issues, legal requirements and lost devices. The mitigation strategy elucidates that while information and communication technologies allow better enforcement of security measures; policies and training provide the desired guidance to influence positive user behaviour among employees. The paper also discusses the need for a balance between usability and security in the success of BYOD in hospitals and hence provides systematic guidelines to curb BYOD security risks in hospitals.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130361236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst the overall well-being of employees in organisations has become the trend in wellness activities at work, existing literature has paid less attention to identifying proper data organisation and management in employer-sponsored personal health records (ESPHRs) for overall health and well-being management of employees. We conducted three focus group discussions with 26 participants comprised of employees and employers to identify information concerns in occupational health and well-being management. We found that health and well-being data can be organised into six main domains when considering the overall health and wellbeing of employees. Consequently, a survey was conducted among 360 respondents to identify employees' and employers' perception of the usefulness of having overall health and well-being information in ESPHRs. We found that both parties accept the importance of all health and well-being information domains in ESPHRs. However, employees believe there is more usefulness in having physical health and healthy behaviour information in ESPHRs, while employers see the importance of work environment, emotional health, basic access and life evaluation information as more useful to have in ESPHRs. Information concerns identified through a thematic analysis were then used to develop an overall health and well-being data model for ESPHRs. These findings suggest that a new data organisation in ESPHRs when profiling employee health and well-being data has a high chance of achieving effective ESPHR system use in organisations.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128961805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, this study proposes a cost-effective LoRa gateway to improve bandwidth utilisation to achieve optimal network throughput for LoRa networks from a hardware design perspective. Secondly, this study creates a design for adaptive and autonomous algorithm to allocate bandwidth while meeting dynamic throughput demands from a network management perspective. This study conducted actual experiments to evaluate the network throughput capacity of a LoRa gateway based on the SemTech™ SX1301 transceiver chipset (SX1301 gateway). This study also addresses the limitations of the SX1301 gateway by proposing a gateway to improve bandwidth utilisation to increase network throughput. Knowing different packet sizes have an impact on network throughput, this study also set up a series of actual experiments related to the network throughput of the proposed gateway with 40 test combinations based on four different packet sizes and ten configurable bandwidth options. These test results were gathered and analysed to establish the throughput threshold for four different packet size ranges, and then to design an adaptive and autonomous algorithm for dynamic bandwidth allocation without human intervention. Based on the theoretical throughput capacity, the proposed gateway has an average improvement of throughput capacity of 57.73%, compared to the SX1301 gateway. The significance of the proposed adaptive algorithm is its capability for monitoring of the network usage constantly and then allocating the bandwidth on demand in an autonomous, agile and scalable fashion.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126197014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The success of using such devices in the healthcare industry depends strongly on secured and reliable medical data transmission. Physicians diagnose that data and prescribe medicines and/or give guidelines/instructions/treatment plans for the patients. Therefore, a physician is always concerned about the medical data trustworthiness, because if it is not guaranteed, a savior can become an involuntary foe! This paper analyses two different scenarios to understand the real-life consequences in IoT-based healthcare (IoT-Health) application. Appropriate sequence diagrams for both scenarios show data movement as a basis for determining necessary security requirements in each layer of IoT-Health. We analyse the individual entities of the overall system and develop a system-wide view of trust in IoT-Health. The security analysis pinpoints the research gap in end-to-end trust and indicates the necessity to treat the whole IoT-Health system as an integrated entity. This study highlights the importance of integrated cross-layer security solutions that can deal with the heterogeneous security architectures of IoT healthcare system and finally identifies a possible solution for the open question raised in the security analysis with appropriate future research directions.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131318426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Routinely collected administrative health data can be a potential and inexpensive alternative to study large population to understand this polypharmacy phenomenon and associated risk. However, synthesizing medication intakes from pharmaceutical records of administrative data can be challenging. In this study, we proposed a graph or network-based approach to understand polypharmacy utilizing the 10% Pharmaceutical and Medicare Benefits Scheme sample data in Australian healthcare context. We proposed methods to identify drug regimens from discrete information of drug dispenses. A polymedication network is then generated from the regimens. We also explored potential relationship among patients' age, medical and pharmaceutical costs and several categories of polymedication regimens. The result showed complex relationships among various drugs and signified the multimorbidity nature of the targeted treatments. Especially the long-term polymedication regimens are found to be focused on treating chronic conditions like cardiovascular diseases, diabetes, asthma, COPD and acid reflux, consistent with the Australian population's disease burden. The methods and networked approach presented in this study can act as a basis for further pharmacovigilance and identifying adverse drug reactions.","PeriodicalId":297760,"journal":{"name":"Proceedings of the Australasian Computer Science Week Multiconference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123965753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
