Introduction: The determination of visit frequency in home-based palliative care (HBPC) is usually based on discretionary and nonstandardised criteria. To reduce variability, the Palliative Care Parametrisation Tool (PCPT) was developed, integrating three clinical parameters: the nursing score (NS), the ESAS -based distress score and the ECOG scale. Following prior validation of the NS, this study corresponds to the second phase of the process: validation of the functioning of the three parameters as a whole.

Methods: A two-round Delphi study was conducted with an expanded panel of experts. About 29 professionals participated in the first round and 28 in the second round. Surveys were distributed via email using Google Forms, with weekly reminders and a 1-month collection period for each round. A 1–10 Likert scale was used, and consensus was defined as ≥80% of scores ≥7.

Results: In the second round, all items reached consensus (83%–97%). Median scores remained high (9–10), with a reduction in interquartile dispersion, indicating consolidation of agreement. The panel confirmed the logic of the PCPT: the NS is the dominant parameter for nursing visits and a modifier for medical visits; the distress score is the dominant parameter for medical visits and a modifier for nursing visits. The ECOG scale acts as a modifier in both cases.

Conclusion: The three PCPT parameters and their operational logic achieved validation by expert consensus. This represents a key step towards the standardisation of the allocation of medical and nursing visits in HBPC and towards the formal implementation of the tool.
