Background and Objectives: Patients express their long wait time as an ineffective patient flow pattern and subsequently patient dissatisfaction. We embarked on this study to ensure an efficient clinic. We used findings from a pilot time-flow study at an academic family practice to identify operational problems that led to excessive patients’ wait time and repeated the study after the practice ...

BACKGROUND Protracted, multi-year wait times exist for bariatric care in Canada. Our objective was to examine wait-listed patients' health status and perceptions regarding the consequences of prolonged wait times using a cross-sectional study design nested within a prospective cohort. METHODS 150 consecutive consenting subjects wait-listed for multi-disciplinary bariatric assessment in a popu...

OBJECTIVE Three experiments examined the effects of various feedback displays on user preference, apparent waiting durations, waiting time reasonableness, and other user experience measures. BACKGROUND User interface guidelines advocate keeping users informed about system status; however, the duration estimation literature shows that focusing on temporal information makes the wait seem longer...

OBJECTIVE To investigate the long term impact of the two week wait rule for breast cancer on referral patterns, cancer diagnoses, and waiting times. DESIGN Prospective cohort study. SETTING A specialist breast clinic in a teaching hospital in Bristol. PARTICIPANTS All patients referred to breast clinic from primary care between 1999 and 2005. MAIN OUTCOME MEASURES Number, route, and out...

Most space-sharing parallel computers presently operated by production high-performance computing centers use batch-queuing systems to manage processor allocation. In many cases, users wishing to use these batch-queued resources may choose among different queues (charging different amounts) potentially on a number of machines to which they have access. In such a situation, the amount of time a ...

This paper uses duration analysis to estimate emergency room wait times. To account for multi-phrasal hazard, analysis time is fitted in a piecewise model that allows hazard to change power and direction whenever it reaches a periodic length. Such model provides a marginal improvement from other competing models where hazard is assumed to be non-monotone or one-time increasing. Results, from ap...

This thesis is a major part of the results within a project called ”Applications of wait/lock-free protocols to real-time systems”. This project is funded by the national Swedish Real-Time Systems research initiative ARTES (www.artes.uu.se) supported by the Swedish Foundation for Strategic Research. The project started in March 1999 and has been running in major with one active Ph.D. student. T...

To have high performance scheduling mechanisms in grid computing, we need accurate methods for estimating parameters like jobs' wait time and run time. In this paper, we consider wait time prediction problem. Different regression techniques are examined on AuverGrid data set to predict wait time. To improve the quality of prediction, some extra features are proposed. Simulation results show tha...

AIMS/METHODS A national data collection exercise was carried out in more than 100 hospital eye service units within the UK to provide clinical and administrative information on patients undergoing cataract surgery. This included patient clinical data such as visual acuity at the time of wait listing and at the time of admission for surgery, presence of other eye disorders, other serious medical...
