A sample size of 54 is sufficient to yield a one-sided 95% confidence interval estimate around our primary outcome measure (proportion of successful transmissions) with a lower bound exceeding the cutpoint for feasibility of 90%, assuming a proportion of 95% successful transmission. Recruitment will be at the orthopedic clinics, using the approved OHRI "Consent for Personal Health Information Review for Research Purposes" obtained through a member of the circle of care. Informed consent will be obtained at the General Pre-Admission Unit (PAU) by the research assistant after eligibility has been determined. A screening process for unicompartment knee arthroplasty and care path for same day discharge is currently in place. For this study, care paths for same day / early discharge for total hip and knee arthroplasty will be confirmed. Theses care paths will include home visits by nursing and physio through the Community Care Access Centre (CCAC).
