The study of patients in Intensive Care Units (ICUs) is a crucial task in critical care research which has significant implications both in identifying clinical risk factors and defining institutional guidances. The mortality study of ICU patients is of particular interest because it provides useful indications to healthcare institutions for improving patients experience, internal policies, and procedures...
Background: Due to the rapid development in industrialization and urbanization, air pollution has aggravated in the past few years, chronic obstructive pulmonary disease (COPD) has become the world's fourth leading cause of death. Through the study of factors affecting medical cost, we find that there is a strong correlation between medical cost and length of stay (LOS). Therefore, it is necessary...
Very often, public policies can only be evaluated after they have been implemented and deployed. The prior simulation of these policies can ensure several benefits: the design can be more accurately adjusted to the objectives of the policy makers; the policies can better reflect the motivations of the individuals involved in several roles (in the case of health services: users, doctors, nurses, civil...
This paper investigates the impact of agents' communication on social simulations using the PAX framework. Previous works investigated the impact of structuring elements (e.g. houses, hospitals, roads, etc) on agents' behaviors. This work extends that, by investigating the combined results of different communication schemes and structural costs. To assess the plausibility of application of these ideas...
Agent-based social simulations have been widely used to help social scientists on the understanding of several social phenomena. Traditional approaches to agents most often tackle well the behavioral and the temporal aspects of the carried out simulations. However, a frequent limitation in social simulations is the lack of simultaneous support for spatial specifications of social structures. That...
High hospital bed occupancy levels have resulted into a shortage of beds to meet increasing demand. This paper describes a bed prediction model in aiding hospital planners to anticipate bed demand so as to manage resources efficiently. Through the regression models, it was found that the number of weekly mean occupied beds is related to both the rainfall and the data on Dengue cases as provided by...
In recent years urban health care has gained more and more concerns. The urban Health Care System (HCS) includes Community Health System (CHS) and Medical Delivery System (MDS). The cooperation between these two systems could make the service more convenient and cost-effective, since cooperation improves effective utilization of recourses. The urban HCS is a complex system and extensively involves...
The research presented in this paper aims at developing and validating a predictive tool of individual exposure to solar Ultra-Violet (UV). UV exposure depends on ambient irradiation level and individual factors related to activity (position to the sun, clothing, duration of exposure, and other forms of sun protection). We predict exposure levels of body parts on basis of ambient irradiation levels...
The paper presents the results of a signal processing approach to detect and isolate systolic murmurs. The identification of the first and second heart sounds and separating systole and diastole from a complete cardiac cycle were successfully carried out through wavelet analysis using an orthogonal Daubechies (db6) wavelet as the mother wavelet. At the fifth level of decomposition, S1 and S2 were...
