Background Policies assigning low-priority patients treatment delays for care, in order to make room for patients of higher priority arriving later, are common in secondary healthcare services today. Alternatively, each new patient could be granted the first available appointment. We aimed to investigate whether prioritisation can be part of the reason why waiting times for care are often...

conclusions according to the results, there was a direct correlation between access to physical space in ed and waiting time. in addition, improving the physical access did not necessarily result in shorter waiting time. therefore, to improve triage process, improvement of waiting time indices, and modifying forms of work process in ed are recommended. results the correlation between the waitin...

the purpose of this study is estimate waiting time of frost occurrence over iran. the daily data from 663 synoptic and climatology over iran during 1/1/1340 to 11/10/1383 have been used. data interpolated by kriging method on 15ã—15 km pixels. the data base with dimension 15992ã—7187 obtained that on the rows were days and on the column were pixels. by t student test the interval mean of waitin...

Suppose that you are going to school and arrive at a bus stop. How long do have wait before the next arrives? Surprisingly, it is longer—possibly much longer—than what might guess from looking schedule. This phenomenon, which called waiting-time paradox, has purely mathematical origin. In this article, we explore explain why occurs, discuss some of its implications (beyond possibility being lat...

the waiting time between children births are called tempo. this phenomenon plays a crucial role in the child and mother health. the purpose of the present study is determination of factors which influence this variable of interest. a significance level of 5% and power of 80% considered to calculate the required sample size for this cross sectional study. the sample size of 124 women determined ...

In this paper, we have proposed a new variant of Round Robin scheduling algorithm by executing the processes according to the new calculated Fit Factor ‘f’ and using the concept of dynamic time quantum. We have compared the performance of our proposed Fittest Job First Dynamic Round Robin(FJFDRR) algorithm with the Priority Based Static Round Robin(PBSRR) algorithm. Experimental results show th...

BACKGROUND It is globally agreed that a well-designed health system deliver timely and convenient access to health services for all patients. Many interventions aiming to reduce waiting times have been implemented in Chinese public tertiary hospitals to improve patients' satisfaction. However, few were well-documented, and the effects were rarely measured with robust methods. METHODS We condu...

Improving productivity in emergency services and managing limited resources of emergency room(ER) are key challenges for health managers of oil industry. One critical and costly resource is ER personnel  and its lack can lead to long queue of patients. Thus appropriate scheduling for nurses and physicians can help ER managers to  get maximum benefit of their current human resource and reduce th...

Minimizing waiting time for tasks waiting in the queue for execution is one of the important scheduling criteria which took a wide area in scheduling preemptive tasks. In this paper we present Changeable Time Quantum (CTQ) approach combined with the round-robin algorithm, we try to adjust the time quantum according to the burst times of the tasks in the ready queue. There are two important bene...
