Screening for Palliative Care Need in Oncology: Validation of Patient-Reported Outcome Measures

Leading oncology societies recommend monitoring symptoms and support needs through patient-reported outcome measures (PROMs), but their use for assessing specialist palliative care (SPC) need has not yet been explored. Research on SPC integration has focused on staff-assessed screening tools, which are time-consuming.

This study aimed to assess the diagnostic validity of the Integrated Palliative Outcome Scale (IPOS) and NCCN Distress Thermometer (NCCN DT) in identifying need for SPC in patients with incurable cancer.

In a cross-sectional study, patients with incurable cancer (prognosis <2 years) completed PROMs. In an independent process, the palliative care consultation service (PCCS) assessed the need for SPC in each patient through multiprofessional case review, and this was used as the reference standard. ROC analyses were employed to determine diagnostic validity.

Of the 208 participants, 71 (34.1 %) were classified as having SPC need by the PCCS. Aiming for a minimum sensitivity of 80%, a cut-off of ≥2 items with high/very high burden in the IPOS resulted in a 90.2% sensitivity (specificity = 50; AUC = 0.791; CI 95%= 0.724-0.858). A cut-off of ≥5 resulted in a sensitivity of 80 % for NCCN DT (specificity = 49.5 %; AUC = 0.687; CI 95% = 0.596-0.777).

PROMs are useful for identifying SPC need in cancer patients. Their implementation might facilitate timely integration of SPC. Future research should focus on an integrated assessment approach with PROMs that combines the requirements of the different specialties to save patient and staff resources.
