Calculating Variance in Healthcare

1. The invasive radiology department has just purchased a piece of equipment, which enables them to be able to perform many of their procedures faster. One of the results of this improve-ment is that they are able to schedule 20% more cases on an average weekday. During the preplanning of this improvement, the director of short stay was not included and was told her staffing needs might increase by 10%. After the first month of the use of the new equipment, the short stay unit had variances as seen below.

Which of the variances below are positive and which ones are negative?

What does the director need to report to senior leadership as to what has happened and why, and what she is doing to make appropriate adjustments?
Volume (patients) 1,000 1,200 200 Overtime hrs (staffing) 50 75 25 Supplies 5,000 5,100 100
