Patterns of integrating palliative care into standard oncology in an early ESMO designated center: a 10-year experience

Abstract

Background: Integration of specialist palliative care (PC) into standard oncology care is recommended. This study investigated how integration at the Cantonal Hospital St. Gallen (KSSG) was manifested 10 years after initial accreditation as a European Society for Medical Oncology (ESMO) Designated Center (ESMO-DC) of Integrated Oncology and Palliative Care.

Methods: A chart review covering the years 2006-2009 and 2016 was carried out in patients with an incurable malignancy receiving PC. Visual graphic analysis was utilized to identify patterns of integration of PC into oncology based on the number and nature of medical consultations recorded for both specialties. A follow-up cohort collected 10 years later was analyzed and changes in patterns of integrating specialist PC into oncology were compared.

Results: Three hundred and forty-five patients from 2006 to 2009 and 64 patients from 2016 were included into analyses. Four distinct patterns were identified using visual graphic analysis. The 'specialist PC-led pattern' (44.9%) and the 'oncology-led pattern' (20.3%) represent disciplines that took primary responsibility for managing patients, with occasional and limited involvement from other disciplines. Patients in the 'concurrent integrated care pattern' (18.3%) had medical consultations that frequently bounced between specialist PC and oncology. In the 'segmented integrated care pattern' (16.5%), patients had sequences of continuous consultations provided by one discipline before alternating to a stretch of consultations provided by the other specialty. In the 2016 follow-up, while the 'oncology-led pattern' occurred significantly less frequently relative to the 'specialist PC-led pattern' and the 'segmented integrated care pattern', the 'concurrent integrated care pattern' emerged more frequently when compared with the 2006-2009 follow-up.

Conclusion: The 'specialist PC-led pattern' was the most prominent pattern in this data. The 2016 follow-up showed that a growing number of patients received a collaborative pattern of care, indicating that integration of specialist PC into standard oncology can manifest as either segmented or concurrent care pathways. Our data suggest a closer, more dynamic and flexible collaboration between oncology and specialist PC early in the disease course of patients with advanced cancer and concurrent with active treatment.
