Optimizing Patient Positioning to Reduce Variation in the Measurement of Breast Cancer-Related Lymphedema.

Prospective lymphedema screening is recommended for breast cancer patients. We observed interoperator variation in perometer-acquired arm volume measurements (P-AVMs) due to patient instability during measurements. We hypothesized that improved positioning during perometry would reduce P-AVM variability.

Prevalence, predictors and economic consequences of no-shows.

Background: Patients not attending to clinic appointments (no-show) significantly affects delivery, cost of care and resource planning. We aimed to evaluate the prevalence, predictors and economic consequences of patient no-shows.

Method: This is a retrospective cohort study using administrative databases for fiscal years 1997-2008.
