Elective Surgery Waiting List data collection (ESWL)

The Elective Surgery Waiting List (ESWL) is also known as the Elective Surgery Booking List (BLIS).

The ESWL is a data collection that includes essential details about people who have been assessed as needing elective surgery by a medical clinician but for whom admission can be delayed for at least 24 hours. These patients are managed via a public hospital waiting list system. Patients are clinically assessed using a national classification system based on the level of need. The three categories are:

Category 1: Procedures that are clinically indicated within 30 days

Category 2: Procedures that are clinically indicated within 90 days

Category 3: Procedures that are clinically indicated within 365 days

ESWL information allows SA Health to assess the effectiveness of waiting times for elective surgery, support elective surgery strategies, inform the community and service providers about waiting times for elective surgery, assist in the management of patient waiting lists and meet national reporting obligations.
