  • The ToCPP is sponsored by the Chief Allied Health Officer, Clinical Excellence Queensland.

    A project oversight committee, consisting of key stakeholder representatives, provides guidance and endorsement relating to the development and implementation of the project model of care.

    A ToCPP project officer was appointed to facilitate project scoping, design, implementation and evaluation.

  • The project model of care has been endorsed by the ToCPP oversight committee following consultation with stakeholders.

  • The ToCPP model of care is dependent on the patient’s risk of readmission. Risk will be determined using the LACE index for readmission.[1]

    THE LACE index predicts patient risk of readmission or death within 30 days of discharge from medical and surgical wards. The tool has been validated in several studies.[2],[3]

    Risk of readmission is calculated as a score from 1– 19 based on the following criteria:

    • Length of stay
    • Acuity of admission (acute or elective)
    • Charlson Co-morbidity index
    • Number of Emergency presentations within the previous 6 months (not including the current admission)

    Risk is attributed as follows:

    • High risk: ≥ 10 points
    • Moderate risk: 5-9 points
    • Low risk: 1-4 points

    Online calculators are available for clinicians to calculate the LACE score [4]:

    Note: patients who are LACE classified as having a low or moderate risk of readmission can be managed under the high risk pathway in the following circumstances:

    • Treating team referral for post-discharge follow-up
    • Identified risk of medicine misadventure

    • A service evaluation will be undertaken with service providers and users to determine perceptions, service benefits, sustainability, and the facilitators and barriers to implementation.
    • An economic evaluation will be undertaken to determine the economic impact of the service.
