You are a senior auditor working on the Shady Oaks Centre engagement for 2023 and are currently in the risk assessment phase of the audit. In discussions with management, you discover that Shady Oaks has recently acquired two new full-body scanning machines. These machines use the latest technology and cost the company more than $10 million each. Although they are more than 50 percent more likely to detect abnormalities, new academic studies suggest there may be potential long-term side effects for patients scanned by these machines. However, because the machines are new, the evidence about long-term effects will not be known for many more years. Despite this, there has been some bad press for Shady Oaks, highlighting the potential risks to patients.
Shady Oaks charges a premium price for patients using the scanning machines, and there is extremely high demand. To manage the demand, Shady Oaks requires that all patients pay for their scans in full at the time of booking, and the payments are immediately recognized as revenue by the centre.
Shady Oaks has taken bookings for four months in advance—although it is only April 2023, the centre has bookings for July and August 2023.
The Canadian Medical Association is currently reviewing the use of the scanning machines and is considering banning their use within Canada until the issue is resolved. A decision is expected on August 1, 2023, and managers tell you that they believe there is an 80-percent chance the scanners will be approved.
