The Palliative Performance Scale (PPS) is a functional assessment tool that informs the level/type of support services required by people with palliative/end-of-life (EOL) needs. Forest Heights Long Term Care Centre (FHLTCC) studied the initial PPS implementation at FHLTCC through mixed-methods analysis, hypothesizing that using the PPS would be a quick/reliable determination of residents’ decline, providing timely/accurate data that translates into appropriate support interventions at EOL; and asking “what are the interdisciplinary teams’ perceptions of the PPS implementation?” Comparative statistical analysis of PPS, PSI, and CHESS scores of residents who died over six months showed that 90% of residents with completed PPS were assessed closer to their death compared to PSI and CHESS, of which 75% showed that PPS at EOL indicated they were closer to death. Themes from exploratory focus groups conducted with 57 interdisciplinary staff showed the growing pains of a care community working through coalescing evidenced-based practice implementation.
