Cost analysis of COVID-19 test result notification using an automated messaging system compared to a staff caller...

In Alberta, polymerase chain reaction (PCR) COVID-19 tests were an important step in detecting and isolating contagious individuals throughout the pandemic. Initially, a staff member provided results to all PCR COVID-19 test clients by phone. As the number of tests increased, new approaches were essential for timely result notification.

An innovative automated IT system was introduced during the pandemic to reduce workloads and support timely result notification. At the time of the COVID-19 test booking and again following swabbing, clients had an option to consent to receive their test results via an automated text or voice message. Prior to implementation, a privacy impact assessment was approved, a pilot was undertaken, and changes to lab information systems were made.

Health administration data were used in a cost analysis to compare the unique costs associated with the novel automated IT practice (e.g., administration, integration, messages, staffing costs) and a hypothetical staff caller practice (e.g., administration, staffing costs) for negative test results. The costs of sharing 2,161,605 negative test results in 2021 were assessed. The automated IT practice demonstrated a cost savings of $6,272,495 over the staff caller practice. A follow-up analysis determined the cost savings threshold of 46,463 negative tests to break even.

Using an automated IT practice for consenting clients can be a cost-effective approach to reach clients in a timely manner during a pandemic or other instances warranting direct notification. This approach is being explored for test result notification of other communicable diseases in other contexts.
