ABSTRACTCataract surgery is the highest-volume surgical procedure in Canada, with over 200,000 performed annually, mostly (85%) on persons aged 65 or older. Concerns have been raised about wait times to access this procedure. This study explores the relationship between waiting times for cataract surgery in Manitoba and a variety of characteristics, including age, sex, socio-economic status, region of residence, health status, surgeon, and surgeon's caseload. The study included 6,114 individuals who had first-eye cataract surgery between November 1, 1998, and March 31, 2000, in Winnipeg, MB. Significant predictors of variation in wait times were age, sex, having a hospitalization while waiting, and surgeon. The model explained 32.5 per cent of the variance in wait times; specific surgeon independently explained 29.5 per cent of the variance. Median waiting times varied widely by surgeon, ranging from 61 to 399 days. Differences in surgeons' expected wait times should be available to patients and referring clinicians.

A recurrent problem in designing interactive computer systems is the inability of system designers, users, and implementors to observe the system's external behavior until implementation has occurred. This, in turn, often results in failure to detect design deficiencies until a point when corrections are costly or impractical. A simulation tool is described which allows a systems designer to interactively specify, implement, demonstrate, evaluate, and iteratively modify an operational simulation of the proposed system's user-computer interface. The tool is intended for hands-on usage by an applications-oriented systems designer with little or no formal training in computer software programming. The capabilities and characteristics of the tool are described along with an economical and efficient approach to its design and implementation.

Purpose To provide an overview of communication characteristics exhibited by individuals with Angelman Syndrome (AS) and special considerations associated with the design and implementation of augmentative and alternative communication (AAC) programs. Method Results of recent studies exploring individuals' uses of AAC are reviewed, with particular emphasis on factors related to individuals' acceptance and successful uses of AAC systems. Results Not applicable Conclusion Despite their inconsistent access to practices previously found to foster individuals' acceptance of AAC systems, individuals with AS demonstrate the ability to use AAC systems, including high-tech AAC devices, successfully.
