Palliative Care Phase: inter-rater reliability and acceptability in a national study.

Area of Science:

• Palliative Care Medicine
• Healthcare Quality Improvement
• Clinical Assessment Tools

Background:

• The Palliative Care Phase model, developed in Australia, categorizes patient status into five phases: stable, unstable, deteriorating, terminal, and bereavement.
• This model is routinely utilized for clinical communication, care planning, quality enhancement, and funding allocation.

Purpose of the Study:

• To evaluate the reliability and acceptability of revised definitions for the Palliative Care Phase.
• To ensure the Palliative Care Phase tool is a robust measure for clinical application.

Main Methods:

• A multi-center, cross-sectional study was conducted across 10 Australian palliative care services.
• Pairs of clinicians independently assessed 410 patients using revised Palliative Care Phase definitions.
• Assessments were performed by 102 nursing and medical clinicians, with 90.7% of ratings completed within 2 hours.

Main Results:

• Substantial overall agreement was found between clinicians' ratings of Palliative Care Phase (kappa = 0.67).
• Moderate inter-rater reliability was observed across all participating sites.
• The Palliative Care Phase was deemed acceptable, with few difficulties in assigning patients to phases, though the 'deteriorating' phase presented the most challenge.

Conclusions:

• The Palliative Care Phase is a reliable and acceptable measure for policy makers, funders, and clinicians.
• This validated tool supports effective care planning, quality improvement initiatives, and funding processes in palliative care settings.
